Definitions
- Shaving cream brushes are used to apply shaving cream to a person's skin prior to wet shaving.
- Shaving cream brushes typically include a handle and bristles attached to one end of the handle. Usually the bristles are dipped into a cup containing shaving cream and then the shaving cream that is retained on the bristles is applied to one's skin, e.g. the face for a man and the underarms and legs for a woman.
- the bristles are boar's hair that are tightly packed into a cylindrical configuration having a smaller circular diameter at a proximal end where the bristles attach to the handle.
- the bristles flare out to a larger diameter flared end at distal ends of the bristles.
- the flared end which is typically circular, is useful to quickly apply shaving cream over large areas.
- Most shaving brushes do not include an integrated shaving cream supply.
- Those brushes that do include an integrated shaving cream supply typically do not include a mechanism to provide a metered dollop or dose of shaving cream.
- the shaving brushes that do include an integrated shaving cream supply are typically not configured to retain the dollop of cream on the brush as the cream is being applied to one's skin. Cream that falls off of the brush can fall onto the floor or into a sink basin resulting in a mess. This cream is also oftentimes wasted.
- FIG. 1 is a perspective view of a shaving cream dispenser.
- FIG. 2 is a cross-sectional view of the shaving cream dispenser shown in FIG. 1 .
- FIG. 3 is an exploded view of the dispenser showing a lower side of the components of the dispenser.
- FIG. 4 is an exploded view of the dispenser showing an upper side of the components of the dispenser.
- FIG. 5 is a top plan view of a rotating hub and spring found in the dispenser of FIG. 1 .
- a shaving lotion dispenser that overcomes the aforementioned shortcomings includes a container and a brush head connected to the container.
- the container defines a longitudinal axis and includes an outlet opening.
- the brush head as mentioned above, is connected to the container and includes a plurality of bristles extending away from the container generally parallel to the longitudinal axis.
- the brush head includes an opening for providing communication between an internal compartment of the container and ambient. Distal ends of the bristles define a contact surface for contacting an associated person's skin. The contact surface is bounded by a non-circular periphery.
- a dispenser that overcomes the aforementioned shortcomings includes a container and a silicone or elastomer brush head connected to the container.
- the container defines a longitudinal axis and includes an outlet opening.
- the brush head includes a base and a plurality of bristles.
- the bristles are integrally formed with the base.
- the base is connected to the container and covers the outlet opening of the container.
- the base includes an opening in communication with the outlet opening of the container.
- the bristles extend away from the base substantially parallel to the longitudinal axis. Distal ends of the bristles define a contact surface for contacting an associated person's skin.
- a dispenser 10 that is useful for dispensing shaving cream.
- the dispenser stores a “propellantless” shaving cream or shaving lotion (hereinafter referred to as “product” for the sake of brevity).
- product a “propellantless” shaving cream or shaving lotion
- the dispenser 10 depicted in the figures is designed to be non-refillable and discarded after the product has been dispensed from the dispenser.
- the product is “propellantless” in that it is not charged with a gas and stored under pressure to propel the product out of the dispenser.
- the product could be charged with a gas propellant and the dispenser would include a mechanism to open a valve to discharge the product.
- the dispenser 10 in the depicted embodiment includes a cap 12 , a brush head 14 , a bezel 16 , a container 18 , a plunger 22 , an insert 24 , a lead screw 26 , a spring 28 , and a hub 32 .
- the cap 12 fits onto the container 18 to protect the brush head 14 .
- the cap is a cup-shaped piece of plastic.
- the cap 12 has a generally triangular configuration normal to a longitudinal axis 34 ( FIG. 2 ) of the dispenser 10 .
- the cap 12 includes a flared lower end 36 that flares outwardly with respect to the longitudinal axis 34 to contact the bezel 16 to limit the downward movement of the cap 12 when the cap is placed over the brush head 14 .
- the brush head 14 connects to the container 18 .
- the brush head 14 includes a plurality of bristles 40 extending away from the container 18 generally parallel to the longitudinal axis 34 .
- the bristles 40 have a slight taper so that a lower (proximal) end of each bristle has a slightly larger diameter than the distal (upper) end.
- Distal ends 42 of the bristles 40 define a contact surface for contacting a person's skin. The contact surface slopes downwardly away from the longitudinal axis 34 .
- the distal ends 42 of the bristles 40 are positioned vertically below the lower surface of the uppermost portion of the cap 12 so as not to be deformed when the cap is placed over the brush head 14 .
- each bristle 40 extends parallel to the longitudinal axis, e.g. the distal ends do not flare out, the sides of the cap do not contact the bristles.
- the central axes of the bristles are generally parallel to each other, i.e., the distal ends of the bristles do not flare outwardly.
- the lower end of each bristle 40 is spaced from the lower end of adjacent bristles. In other words, a space is provided between a lower side surface of each bristle and a respective lower side surfaces of adjacent bristles.
- each bristle 40 is approximately 11 ⁇ 2 inches from the base 50 .
- the bristles 40 can be shorter as compared to known shaving brushes while still providing an airy lather without the need for propellant because the bristles 40 , as well as the entire brush head 14 , is made from a very flexible material and the flexibility of the bristles assist in lathering. The softness of the bristles also provides a desirable feel on the skin of the individual using the dispenser.
- the contact surface is bounded by a non-circular periphery 44 .
- the non-circular periphery 44 is generally triangular in shape normal to the longitudinal axis 34 ( FIG. 2 ).
- the contact surface can take other alternative configurations; however, tighter radii sections 46 at the corners of the contact surface facilitate the application of shaving cream in narrow areas, for example, the sideburn area of a man's face.
- Larger radius sections 48 that extend between the tighter radii 46 provide a similar advantage as the large flared end of known shaving brushes, e.g., easy application of the shaving cream to areas of the skin that are not near areas where it is undesirable to apply shaving cream, such as on the nose or upper lip of a man.
- the brush head includes a base 50 that generally defines an opening 52 ( FIG. 2 ) in communication with an internal compartment 54 of the container 18 and ambient.
- the base 50 and the bristles 40 are an integrally formed piece (a one-piece member) made from silicone or an elastomer.
- the brush head 14 also includes an integrally formed apron 56 that contacts the container 18 to operate as a gasket to contain the product within the container 18 .
- the base 50 is generally triangular in configuration normal to the longitudinal axis 34 .
- the apron 56 is generally cylindrical in configuration, i.e., circular in a cross section taken normal to the longitudinal axis 34 .
- the brush head 14 also includes an integrally formed tube 58 that extends upwardly from the base 50 generally surrounding the opening 42 ( FIG. 2 ).
- the tube is generally cylindrical in configuration and defines a passage 62 that is in communication with the opening 42 , and thus the internal compartment 44 of the container 18 , as well as ambient.
- the tube 58 is coaxial with the longitudinal axis 34 .
- the tube includes slits 64 that operate as a valve, which will be described in more detail below, that when opened provides communication to ambient.
- the slits 64 can be replaced by a duckbill valve.
- the brush head 14 which includes the apron 56 , the base 50 , the tube 58 , and the bristles 40 is an integrally formed, i.e., one-piece, member made from a flexible e.g., rubber-like material such as silicone or thermoplastic elastomer (TPE).
- TPE thermoplastic elastomer
- the material from which the brush head 14 is made has a low durometer which allows the bristles 40 to be very flexible and also allows the slits 64 in the tube 58 to operate as a valve that is integrated into the brush head 14 . This aids in manufacturing by reducing the number of components of the dispenser.
- the bezel 16 connects to an upper substantially triangular (normal to the longitudinal axis) edge of the container 18 .
- the bezel 16 in the depicted embodiment is made of plastic and closes a portion of the container 18 and acts to retain the brush head 14 to the container.
- the periphery of the bezel 16 is generally triangular normal to the longitudinal axis 34 .
- the bezel 16 includes a generally triangular recess 70 that is shaped to receive the base 50 of the brush head 14 .
- the bezel 16 includes a central generally circular opening 72 that is concentric with the longitudinal axis 34 . As is more clearly seen in FIG.
- a downwardly depending cylindrical boss 74 surrounds the opening 72 .
- Radial tabs 76 extend inwardly from an upper circular edge of the downwardly depending cylindrical boss 74 towards the center of the central opening 72 .
- the radial tabs 76 engage the brush head 14 between the base 50 and the apron 56 to retain the brush head and fix it with respect to the bezel 16 .
- curved slots 78 are formed in each radial tab 76 and are spaced radially inwardly from the cylindrical boss 74 .
- a generally triangular apron 82 depends downwardly in the same direction as the cylindrical boss 74 and is radially spaced outward from the cylindrical boss 74 .
- the bezel 16 fits onto the container 18 .
- the container 18 stores the product and includes the internal compartment 54 that was described above.
- the container 18 includes a side wall 90 that is generally triangular in cross-section normal to the longitudinal axis 34 ( FIG. 2 ) having flattened corner areas 92 . Accordingly, in the depicted embodiment the container is generally six sided. Longitudinal grooves 94 are formed along sidewall in the flattened corner areas 92 .
- the container 18 includes a top wall 96 .
- a flared upper section 98 which is generally triangular normal to the longitudinal axis 34 , extends upwardly from the top wall 96 to engage the bezel 16 .
- Outer struts 102 which are angularly spaced 120 degrees from one another with respect to the longitudinal axis 34 , extend inwardly from the flared upper section 98 and upwardly from the top wall 96 .
- the outer struts 102 terminate radially at an outer cylindrical boss 104 that is normal to the top wall 96 .
- the outer cylindrical boss 104 is coaxial with the longitudinal axis 34 ( FIG. 2 ).
- the cylindrical apron 56 of the brush head 14 contacts an inner surface of the outer cylindrical boss 104 to operate as a gasket to maintain the product within the internal compartment 44 of the container 18 .
- Flexible tabs 106 are formed with the outer cylindrical boss 104 and are shaped to be received inside the curved slots 76 formed in the bezel 16 to connect the bezel to the container.
- the downwardly depending cylindrical boss 74 of the bezel 16 surrounds the outer cylindrical boss 104 of the container 18 (see FIG. 2 ).
- Inner radial struts 110 extend inwardly from the outer cylindrical boss 104 to connect with an inner cylindrical boss 112 .
- the inner radial struts 110 are spaced below an upper edge of the outer cylindrical boss 104 .
- the inner radial struts 110 are angularly spaced 120 degrees from one another with respect to the longitudinal axis 34 ( FIG. 2 ).
- the inner cylindrical boss 112 is stepped and coaxial with the longitudinal axis 34 (see FIG. 2 ).
- the outer circular boss 104 generally defines the outlet opening 114 of the container 18 . Accordingly, product exits the container 18 via the outlet opening 114 , either around the struts 110 in the space between the outer boss 104 and the inner boss 112 or through the inner cylindrical boss 112 .
- the container 18 also includes a lower opening 116 .
- Inwardly protruding lower tabs 118 extend inwardly into the internal compartment 54 from the sidewall 90 . These tabs 118 engage the insert 24 to connect the container 18 to the insert 24 in a manner that will be described in more detail below.
- the plunger 22 pushes product out of the internal compartment 54 of the container 18 towards the brush head 14 .
- the plunger 22 has a complementary shape to the inside of the container 18 so that a peripheral edge of the plunger 22 contacts an inner surface of the container 18 to press the product out of the internal compartment 54 through the outlet opening 114 of the container.
- the plunger 22 is generally triangular normal to the longitudinal axis 34 ( FIG. 2 ) having the same six-sided configuration as the sidewall 90 of the container 18 .
- the plunger 22 includes an upper edge 122 that contacts an internal surface of the sidewall 90 of the container 18 .
- An additional lower peripheral contact edge 124 also contacts the internal surface of the container 90 .
- the plunger also includes a centrally located boss 126 having a threaded opening 128 .
- the lead screw 26 threads into the threaded opening 128 and cooperates with the plunger 22 in a manner that will be described in more detail below.
- the insert 24 is received in the rotating hub 32 and the container 18 .
- the insert 24 includes a generally triangular upper section 132 and a generally cylindrical lower section 134 . More particularly, the upper section 132 of the insert 124 is the same generally six-sided configuration as the plunger 22 and the sidewall 90 of the container 18 .
- Tabs 136 extend outwardly away from a peripheral edge surface of the upper section 132 and engage the tabs 118 ( FIG. 3 ) located at a lower end on an internal surface of the container 18 to fix the container 18 to the insert 24 .
- the insert 24 also includes flexible tabs 138 that extend downwardly from the triangular section 132 and terminate near a lower edge of the lower circular cylindrical lower section 134 of the insert 24 .
- the flexible tabs 138 engage the rotating hub 32 in a manner that will be described in more detail below.
- the insert 24 also includes a central opening 142 that receives the lead screw 26 .
- the central opening 142 is unthreaded and larger than the portion of lead screw received in the central opening so that the lead screw freely rotates within the central opening 142 .
- the central opening 142 is coaxial with the longitudinal axis 34 ( FIG. 2 ).
- a pawl 144 extends downwardly from a lower base surface of the insert 24 and is offset inwardly from the periphery of the cylindrical lower section 134 of the retainer 24 .
- the pawl 144 cooperates with the lead screw 26 in a manner that will be described in more detail below.
- Posts 146 which are angularly displaced from the pawl 144 with respect to the longitudinal axis 34 also depend downwardly from a lower base surface and are offset inwardly from the periphery of the cylindrical lower section 134 of the insert 24 .
- the posts 146 cooperate with the spring 28 in a manner that will be described in more detail below.
- the lead screw 26 includes a threaded rod 150 that extends upwardly from and is connected to a ratchet wheel base 152 .
- the threaded rod 150 is cylindrical in configuration and coaxial with the longitudinal axis 34 ( FIG. 2 ).
- the threaded rod 150 is inserted into the central opening 142 of the insert 24 and is threaded into the threaded opening 128 in the plunger 22 .
- the threaded rod 150 extends into the inner boss 112 at the top of the container 18 .
- Rotation of the ratchet wheel 152 results in rotation of the threaded rod 150 .
- Rotation of the threaded rod 150 results in the plunger 22 moving linearly upwardly with respect to the longitudinal axis 34 ( FIG. 2 ) because of the engagement between the plunger 22 and the container 18 .
- the ratchet wheel base 152 is trapped between the insert 24 and the rotating hub 32 .
- the spring 28 is disposed below the ratchet wheel base 152 of the lead screw 26 and attaches to the rotating hub 32 .
- the spring 28 is an integrally formed piece, which can be made from plastic or metal, that includes a generally annular outer section 160 having a radial extension 162 that extends radially outwardly from the annular section 160 .
- the radial extension 162 is trapped between the posts 146 ( FIG. 3 ) of the insert 24 , the reason for which will be described in more detail below.
- the spring 28 also includes a coiled member 164 that is integrally formed with the annular outer member 160 .
- the coiled member 164 defines a central keyed opening 166 .
- the hub 32 has a generally triangular outer periphery normal to the longitudinal axis 34 to generally follow the configuration of the lower edge of the container 18 .
- the hub 32 includes a cylindrical recess 170 that is complementary in shape to the cylindrical lower section 134 of the insert 24 to receive the lower section.
- a keyed extension 172 extends upwardly coaxial with the longitudinal axis 34 to be received inside the keyed opening 166 in the spring 28 . Since the radial extension 162 is trapped between the posts 146 ( FIG. 3 ) of the insert 24 , rotation of the hub 132 results in the coiled portion 164 of the spring 28 to constrict about the longitudinal axis 34 to provide a resistance against rotation of the hub 32 .
- the hub 32 includes slots 174 that are radially offset from the cylindrical recess 170 formed in the hub 32 which receive the flexible tabs 138 that depend downwardly from the insert 24 to connect the insert to the hub 32 .
- Rotation of the insert 24 along with the hub 32 is precluded due to the configuration of the generally triangular upper section 132 of the insert 24 engaging the sidewall 90 of the container 18 , which is non-circular in a cross section taken normal to the longitudinal axis 34 .
- a pawl 176 is also formed in the recess 170 of the hub 32 and cooperates with the ratchet wheel 152 .
- an inwardly protrubing catch 178 extends from a peripheral edge of the recess 170 to cooperate with the spring in a manner to be described in more detail below.
- the hub also includes grooves 180 that align with the grooves 94 formed in the container 18 to provide a visual indication of dosing.
- an operator rotates the hub 32 in a clockwise direction (per the orientation of FIG. 4 ).
- the pawl 176 engages the ratchet wheel 152 which results in the threaded rod 150 rotating.
- Rotation of the threaded rod results in the plunger 22 translating upwardly on the threaded rod 150 forcing product through the outlet opening 114 of the container and into the passage 62 formed in the brush head 14 .
- the pressure 62 upstream from the slits 64 results in the slits opening to allow product to be dispensed from the tube 58 and to be maintained in a well 182 defined on its sides by the adjacent bristles 40 and at its lower end by the upper edge of the tube 58 .
- the spring 28 resists further rotational movement in the clockwise direction as the coiled member 164 constricts around the keyed extension 172 and the longitudinal axis 34 .
- the constriction of the coiled member occurs because the spring 28 rotates with the hub 32 due to the keyed connection between the two, but the radial extension 162 prevents rotation because the radial extension is trapped between the posts 146 extending downwardly from retainer 24 , which does not rotate.
- the pawl 176 pushes the ratchet wheel 152 the pawl 144 ( FIG.
- the hub also includes grooves 180 that align with the grooves 94 formed in the container 18 to provide a visual indication of dosing.
- the catch 178 can eventually contact the rear edge of the pawl 144 to limit further rotation of the hub 32 .
- the hub 32 can then be rotated counterclockwise.
- the pawl 144 on the insert 24 inhibits the ratchet wheel 152 from rotating counterclockwise and the pawl 176 on the hub 32 rides over the ratchet wheel base 152 so that the grooves 180 on the hub 32 can align with the grooves 94 on the container 18 .
- the distance of translational movement of the plunger 22 in the container 18 that results from rotation of the hub 32 from its original position (see FIG. 1 where grooves 180 and grooves 94 align) to where the catch 178 ( FIG. 5 ) contacts the pawl 144 is designed to deliver an appropriate volume, i.e. dollop, for shaving.
- a dispensing mechanism which employs a plunger, for dispensing metered dollops of shaving cream from the internal chamber 54 of the container 18 has been particularly described.
- the product can also be dispensed in other known manners, for example, using other known actuators or by simply squeezing sides of the container 18 , if the container were made from a flexible material that would allow the sides to be squeezed.
- Another example of a dispensing mechanism includes placing the product into a flexible container (similar to a plastic bag) and inserting the “bag” of product into a more rigid container.
- a second flexible container which will be referred to as a bladder, can fill with air or another gas and also be disposed inside the more rigid container.
- the bladder expands, via air (typically from ambient) being introduced in the bladder, the bladder presses against the flexible container filled with product expelling the product from the flexible container and the rigid container.
- the product can then be delivered to a brush similar to the brush head depicted in the described embodiment.
- a shaving cream dispenser has been described with reference to a particular embodiment and alternatives thereof. Modifications and alterations will occur to those upon reading and understanding the detailed description. The invention is not limited to only the embodiment described above. Instead, the invention is broadly defined by the appended claims and the equivalents thereof.
Abstract
Description
- This application claims the benefit of provisional patent application Ser. No. 60/945,210, filed Jun. 20, 2007, which is incorporated by reference in its entirety herein.
- Shaving cream brushes are used to apply shaving cream to a person's skin prior to wet shaving. Shaving cream brushes typically include a handle and bristles attached to one end of the handle. Usually the bristles are dipped into a cup containing shaving cream and then the shaving cream that is retained on the bristles is applied to one's skin, e.g. the face for a man and the underarms and legs for a woman.
- For most shaving cream brushes, the bristles are boar's hair that are tightly packed into a cylindrical configuration having a smaller circular diameter at a proximal end where the bristles attach to the handle. The bristles flare out to a larger diameter flared end at distal ends of the bristles. The flared end, which is typically circular, is useful to quickly apply shaving cream over large areas. These boar's hair shaving brushes having the large circular configuration at their distal end; however, make it difficult to neatly apply shaving cream in certain areas of the face, for example, between a man's nose and his upper lip as well as the sideburn areas.
- In addition to being difficult to neatly fit into certain locations, the tight pack of the bristles makes known shaving brushes difficult to clean. Water cannot easily penetrate between the lower portions of the bristles that are tightly packed together.
- Most shaving brushes do not include an integrated shaving cream supply. Those brushes that do include an integrated shaving cream supply typically do not include a mechanism to provide a metered dollop or dose of shaving cream. Moreover, the shaving brushes that do include an integrated shaving cream supply are typically not configured to retain the dollop of cream on the brush as the cream is being applied to one's skin. Cream that falls off of the brush can fall onto the floor or into a sink basin resulting in a mess. This cream is also oftentimes wasted.

- With reference to
FIG. 1 , adispenser 10 that is useful for dispensing shaving cream is disclosed. The dispenser stores a “propellantless” shaving cream or shaving lotion (hereinafter referred to as “product” for the sake of brevity). Thedispenser 10 depicted in the figures is designed to be non-refillable and discarded after the product has been dispensed from the dispenser. The product is “propellantless” in that it is not charged with a gas and stored under pressure to propel the product out of the dispenser. Alternatively, the product could be charged with a gas propellant and the dispenser would include a mechanism to open a valve to discharge the product. - With reference to
FIGS. 2-4 , thedispenser 10 in the depicted embodiment includes acap 12, abrush head 14, abezel 16, acontainer 18, aplunger 22, aninsert 24, alead screw 26, aspring 28, and ahub 32. A dispenser that falls within the scope of the invention, however, is not required to include all of these components. - The
cap 12 fits onto thecontainer 18 to protect thebrush head 14. In the depicted embodiment, the cap is a cup-shaped piece of plastic. Thecap 12 has a generally triangular configuration normal to a longitudinal axis 34 (FIG. 2 ) of thedispenser 10. Thecap 12 includes a flaredlower end 36 that flares outwardly with respect to thelongitudinal axis 34 to contact thebezel 16 to limit the downward movement of thecap 12 when the cap is placed over thebrush head 14. - The
brush head 14 connects to thecontainer 18. Thebrush head 14 includes a plurality ofbristles 40 extending away from thecontainer 18 generally parallel to thelongitudinal axis 34. Thebristles 40 have a slight taper so that a lower (proximal) end of each bristle has a slightly larger diameter than the distal (upper) end.Distal ends 42 of thebristles 40 define a contact surface for contacting a person's skin. The contact surface slopes downwardly away from thelongitudinal axis 34. Thedistal ends 42 of thebristles 40 are positioned vertically below the lower surface of the uppermost portion of thecap 12 so as not to be deformed when the cap is placed over thebrush head 14. Additionally, since thebristles 40 extend parallel to the longitudinal axis, e.g. the distal ends do not flare out, the sides of the cap do not contact the bristles. The central axes of the bristles are generally parallel to each other, i.e., the distal ends of the bristles do not flare outwardly. Unlike known boar's head brushes, where the bristles are tightly packed together, the lower end of eachbristle 40 is spaced from the lower end of adjacent bristles. In other words, a space is provided between a lower side surface of each bristle and a respective lower side surfaces of adjacent bristles. This facilitates cleaning of thebrush head 14 because water can easily flow between the individual bristles cleaning out any unused product or other debris that may collect making for a very sanitary shaving brush and shaving product dispenser. In the depicted embodiment, thedistal end 44 of eachbristle 40 is approximately 1½ inches from thebase 50. Thebristles 40 can be shorter as compared to known shaving brushes while still providing an airy lather without the need for propellant because thebristles 40, as well as theentire brush head 14, is made from a very flexible material and the flexibility of the bristles assist in lathering. The softness of the bristles also provides a desirable feel on the skin of the individual using the dispenser. - With reference to
FIG. 4 , the contact surface is bounded by anon-circular periphery 44. In the depicted embodiment, thenon-circular periphery 44 is generally triangular in shape normal to the longitudinal axis 34 (FIG. 2 ). The contact surface can take other alternative configurations; however,tighter radii sections 46 at the corners of the contact surface facilitate the application of shaving cream in narrow areas, for example, the sideburn area of a man's face.Larger radius sections 48 that extend between thetighter radii 46 provide a similar advantage as the large flared end of known shaving brushes, e.g., easy application of the shaving cream to areas of the skin that are not near areas where it is undesirable to apply shaving cream, such as on the nose or upper lip of a man. - The brush head includes a base 50 that generally defines an opening 52 (
FIG. 2 ) in communication with aninternal compartment 54 of thecontainer 18 and ambient. In the depicted embodiment, thebase 50 and thebristles 40 are an integrally formed piece (a one-piece member) made from silicone or an elastomer. Thebrush head 14 also includes an integrally formedapron 56 that contacts thecontainer 18 to operate as a gasket to contain the product within thecontainer 18. Thebase 50 is generally triangular in configuration normal to thelongitudinal axis 34. Theapron 56 is generally cylindrical in configuration, i.e., circular in a cross section taken normal to thelongitudinal axis 34. - The
brush head 14 also includes an integrally formedtube 58 that extends upwardly from the base 50 generally surrounding the opening 42 (FIG. 2 ). The tube is generally cylindrical in configuration and defines apassage 62 that is in communication with theopening 42, and thus theinternal compartment 44 of thecontainer 18, as well as ambient. Thetube 58 is coaxial with thelongitudinal axis 34. The tube includesslits 64 that operate as a valve, which will be described in more detail below, that when opened provides communication to ambient. Theslits 64 can be replaced by a duckbill valve. - In the depicted embodiment, the
brush head 14, which includes theapron 56, thebase 50, thetube 58, and thebristles 40 is an integrally formed, i.e., one-piece, member made from a flexible e.g., rubber-like material such as silicone or thermoplastic elastomer (TPE). The material from which thebrush head 14 is made has a low durometer which allows thebristles 40 to be very flexible and also allows theslits 64 in thetube 58 to operate as a valve that is integrated into thebrush head 14. This aids in manufacturing by reducing the number of components of the dispenser. - With reference back to
FIG. 2 , thebezel 16 connects to an upper substantially triangular (normal to the longitudinal axis) edge of thecontainer 18. Thebezel 16 in the depicted embodiment is made of plastic and closes a portion of thecontainer 18 and acts to retain thebrush head 14 to the container. As is more clearly seen inFIGS. 3 and 4 , the periphery of thebezel 16 is generally triangular normal to thelongitudinal axis 34. With reference toFIG. 4 , thebezel 16 includes a generallytriangular recess 70 that is shaped to receive thebase 50 of thebrush head 14. Thebezel 16 includes a central generallycircular opening 72 that is concentric with thelongitudinal axis 34. As is more clearly seen inFIG. 3 , a downwardly dependingcylindrical boss 74 surrounds theopening 72.Radial tabs 76 extend inwardly from an upper circular edge of the downwardly dependingcylindrical boss 74 towards the center of thecentral opening 72. Theradial tabs 76 engage thebrush head 14 between the base 50 and theapron 56 to retain the brush head and fix it with respect to thebezel 16. With reference back toFIG. 4 ,curved slots 78 are formed in eachradial tab 76 and are spaced radially inwardly from thecylindrical boss 74. With reference toFIG. 3 , a generallytriangular apron 82 depends downwardly in the same direction as thecylindrical boss 74 and is radially spaced outward from thecylindrical boss 74. As discussed above, thebezel 16 fits onto thecontainer 18. - The
container 18 stores the product and includes theinternal compartment 54 that was described above. Thecontainer 18 includes aside wall 90 that is generally triangular in cross-section normal to the longitudinal axis 34 (FIG. 2 ) having flattenedcorner areas 92. Accordingly, in the depicted embodiment the container is generally six sided.Longitudinal grooves 94 are formed along sidewall in the flattenedcorner areas 92. With reference toFIG. 4 , thecontainer 18 includes atop wall 96. A flaredupper section 98, which is generally triangular normal to thelongitudinal axis 34, extends upwardly from thetop wall 96 to engage thebezel 16. Outer struts 102, which are angularly spaced 120 degrees from one another with respect to thelongitudinal axis 34, extend inwardly from the flaredupper section 98 and upwardly from thetop wall 96. The outer struts 102 terminate radially at an outercylindrical boss 104 that is normal to thetop wall 96. The outercylindrical boss 104 is coaxial with the longitudinal axis 34 (FIG. 2 ). Thecylindrical apron 56 of thebrush head 14 contacts an inner surface of the outercylindrical boss 104 to operate as a gasket to maintain the product within theinternal compartment 44 of thecontainer 18.Flexible tabs 106 are formed with the outercylindrical boss 104 and are shaped to be received inside thecurved slots 76 formed in thebezel 16 to connect the bezel to the container. The downwardly dependingcylindrical boss 74 of thebezel 16 surrounds the outercylindrical boss 104 of the container 18 (seeFIG. 2 ). - Inner radial struts 110 extend inwardly from the outer
cylindrical boss 104 to connect with an innercylindrical boss 112. The inner radial struts 110 are spaced below an upper edge of the outercylindrical boss 104. The inner radial struts 110 are angularly spaced 120 degrees from one another with respect to the longitudinal axis 34 (FIG. 2 ). The innercylindrical boss 112 is stepped and coaxial with the longitudinal axis 34 (seeFIG. 2 ). The outercircular boss 104 generally defines the outlet opening 114 of thecontainer 18. Accordingly, product exits thecontainer 18 via theoutlet opening 114, either around thestruts 110 in the space between theouter boss 104 and theinner boss 112 or through the innercylindrical boss 112. - With reference to
FIG. 3 , thecontainer 18 also includes alower opening 116. Inwardly protrudinglower tabs 118 extend inwardly into theinternal compartment 54 from thesidewall 90. Thesetabs 118 engage theinsert 24 to connect thecontainer 18 to theinsert 24 in a manner that will be described in more detail below. - The
plunger 22 pushes product out of theinternal compartment 54 of thecontainer 18 towards thebrush head 14. Theplunger 22 has a complementary shape to the inside of thecontainer 18 so that a peripheral edge of theplunger 22 contacts an inner surface of thecontainer 18 to press the product out of theinternal compartment 54 through the outlet opening 114 of the container. In the depicted embodiment, theplunger 22 is generally triangular normal to the longitudinal axis 34 (FIG. 2 ) having the same six-sided configuration as thesidewall 90 of thecontainer 18. Theplunger 22 includes anupper edge 122 that contacts an internal surface of thesidewall 90 of thecontainer 18. An additional lowerperipheral contact edge 124 also contacts the internal surface of thecontainer 90. The plunger also includes a centrally locatedboss 126 having a threadedopening 128. Thelead screw 26 threads into the threadedopening 128 and cooperates with theplunger 22 in a manner that will be described in more detail below. - The
insert 24 is received in the rotatinghub 32 and thecontainer 18. Theinsert 24 includes a generally triangularupper section 132 and a generally cylindricallower section 134. More particularly, theupper section 132 of theinsert 124 is the same generally six-sided configuration as theplunger 22 and thesidewall 90 of thecontainer 18.Tabs 136 extend outwardly away from a peripheral edge surface of theupper section 132 and engage the tabs 118 (FIG. 3 ) located at a lower end on an internal surface of thecontainer 18 to fix thecontainer 18 to theinsert 24. - The
insert 24 also includesflexible tabs 138 that extend downwardly from thetriangular section 132 and terminate near a lower edge of the lower circular cylindricallower section 134 of theinsert 24. Theflexible tabs 138 engage the rotatinghub 32 in a manner that will be described in more detail below. Theinsert 24 also includes acentral opening 142 that receives thelead screw 26. Thecentral opening 142 is unthreaded and larger than the portion of lead screw received in the central opening so that the lead screw freely rotates within thecentral opening 142. Thecentral opening 142 is coaxial with the longitudinal axis 34 (FIG. 2 ). - With reference to
FIG. 3 , apawl 144 extends downwardly from a lower base surface of theinsert 24 and is offset inwardly from the periphery of the cylindricallower section 134 of theretainer 24. Thepawl 144 cooperates with thelead screw 26 in a manner that will be described in more detail below.Posts 146, which are angularly displaced from thepawl 144 with respect to thelongitudinal axis 34 also depend downwardly from a lower base surface and are offset inwardly from the periphery of the cylindricallower section 134 of theinsert 24. Theposts 146 cooperate with thespring 28 in a manner that will be described in more detail below. - The
lead screw 26 includes a threadedrod 150 that extends upwardly from and is connected to aratchet wheel base 152. The threadedrod 150 is cylindrical in configuration and coaxial with the longitudinal axis 34 (FIG. 2 ). The threadedrod 150 is inserted into thecentral opening 142 of theinsert 24 and is threaded into the threadedopening 128 in theplunger 22. The threadedrod 150 extends into theinner boss 112 at the top of thecontainer 18. Rotation of theratchet wheel 152 results in rotation of the threadedrod 150. Rotation of the threadedrod 150 results in theplunger 22 moving linearly upwardly with respect to the longitudinal axis 34 (FIG. 2 ) because of the engagement between theplunger 22 and thecontainer 18. Theratchet wheel base 152 is trapped between theinsert 24 and the rotatinghub 32. - The
spring 28 is disposed below theratchet wheel base 152 of thelead screw 26 and attaches to the rotatinghub 32. Thespring 28 is an integrally formed piece, which can be made from plastic or metal, that includes a generally annularouter section 160 having aradial extension 162 that extends radially outwardly from theannular section 160. Theradial extension 162 is trapped between the posts 146 (FIG. 3 ) of theinsert 24, the reason for which will be described in more detail below. Thespring 28 also includes acoiled member 164 that is integrally formed with the annularouter member 160. Thecoiled member 164 defines a central keyedopening 166. - The
hub 32 has a generally triangular outer periphery normal to thelongitudinal axis 34 to generally follow the configuration of the lower edge of thecontainer 18. Thehub 32 includes acylindrical recess 170 that is complementary in shape to the cylindricallower section 134 of theinsert 24 to receive the lower section. Concentric within therecess 170, akeyed extension 172 extends upwardly coaxial with thelongitudinal axis 34 to be received inside thekeyed opening 166 in thespring 28. Since theradial extension 162 is trapped between the posts 146 (FIG. 3 ) of theinsert 24, rotation of thehub 132 results in the coiledportion 164 of thespring 28 to constrict about thelongitudinal axis 34 to provide a resistance against rotation of thehub 32. - As seen in
FIG. 4 , thehub 32 includesslots 174 that are radially offset from thecylindrical recess 170 formed in thehub 32 which receive theflexible tabs 138 that depend downwardly from theinsert 24 to connect the insert to thehub 32. Rotation of theinsert 24 along with thehub 32 is precluded due to the configuration of the generally triangularupper section 132 of theinsert 24 engaging thesidewall 90 of thecontainer 18, which is non-circular in a cross section taken normal to thelongitudinal axis 34. Apawl 176 is also formed in therecess 170 of thehub 32 and cooperates with theratchet wheel 152. With reference toFIG. 5 , an inwardlyprotrubing catch 178 extends from a peripheral edge of therecess 170 to cooperate with the spring in a manner to be described in more detail below. The hub also includesgrooves 180 that align with thegrooves 94 formed in thecontainer 18 to provide a visual indication of dosing. - To dispense product, an operator rotates the
hub 32 in a clockwise direction (per the orientation ofFIG. 4 ). Thepawl 176 engages theratchet wheel 152 which results in the threadedrod 150 rotating. Rotation of the threaded rod results in theplunger 22 translating upwardly on the threadedrod 150 forcing product through the outlet opening 114 of the container and into thepassage 62 formed in thebrush head 14. Thepressure 62 upstream from theslits 64 results in the slits opening to allow product to be dispensed from thetube 58 and to be maintained in a well 182 defined on its sides by theadjacent bristles 40 and at its lower end by the upper edge of thetube 58. - As the
hub 32 is rotated thespring 28 resists further rotational movement in the clockwise direction as thecoiled member 164 constricts around thekeyed extension 172 and thelongitudinal axis 34. The constriction of the coiled member occurs because thespring 28 rotates with thehub 32 due to the keyed connection between the two, but theradial extension 162 prevents rotation because the radial extension is trapped between theposts 146 extending downwardly fromretainer 24, which does not rotate. As thepawl 176 pushes theratchet wheel 152 the pawl 144 (FIG. 3 ) rides along theratchet wheel base 152 of thelead screw 26 to provide an audible indication of dosing in that thepawl 144 clicks as it rides along the ratchet wheel. The vibration of the click can also be felt by the user to provide another sensory indication of dosing. The hub also includesgrooves 180 that align with thegrooves 94 formed in thecontainer 18 to provide a visual indication of dosing. - The
catch 178 can eventually contact the rear edge of thepawl 144 to limit further rotation of thehub 32. Thehub 32 can then be rotated counterclockwise. Thepawl 144 on theinsert 24 inhibits theratchet wheel 152 from rotating counterclockwise and thepawl 176 on thehub 32 rides over theratchet wheel base 152 so that thegrooves 180 on thehub 32 can align with thegrooves 94 on thecontainer 18. The distance of translational movement of theplunger 22 in thecontainer 18 that results from rotation of thehub 32 from its original position (seeFIG. 1 wheregrooves 180 andgrooves 94 align) to where the catch 178 (FIG. 5 ) contacts thepawl 144 is designed to deliver an appropriate volume, i.e. dollop, for shaving. - A dispensing mechanism, which employs a plunger, for dispensing metered dollops of shaving cream from the
internal chamber 54 of thecontainer 18 has been particularly described. The product can also be dispensed in other known manners, for example, using other known actuators or by simply squeezing sides of thecontainer 18, if the container were made from a flexible material that would allow the sides to be squeezed. Another example of a dispensing mechanism includes placing the product into a flexible container (similar to a plastic bag) and inserting the “bag” of product into a more rigid container. A second flexible container, which will be referred to as a bladder, can fill with air or another gas and also be disposed inside the more rigid container. As the bladder expands, via air (typically from ambient) being introduced in the bladder, the bladder presses against the flexible container filled with product expelling the product from the flexible container and the rigid container. The product can then be delivered to a brush similar to the brush head depicted in the described embodiment. - A shaving cream dispenser has been described with reference to a particular embodiment and alternatives thereof. Modifications and alterations will occur to those upon reading and understanding the detailed description. The invention is not limited to only the embodiment described above. Instead, the invention is broadly defined by the appended claims and the equivalents thereof.
