  • mating surface 18 of each bottle half forms a generally flat plane with a helical twist or, alternatively described, the helical mating surface has a planar cross section.
  • the flat shape is preferred because it allows both bottle halves to be manufactured as the same part.
  • the mating surface may be shapes other than flat, such as concave and convex and may have male and female joining features, but any such features or shapes that are not symmetrical require that the bottle halves are formed as two separate parts from different molds.
  • the mating surfaces sit adjacently together along the flat twisted plane that is formed at the angle of helical rotation.
  • This helical shaping particularly if 180° of twist or greater, allows the contents of the two cavities of the combined bottle to be viewed from any aspect thereby enhancing the marketability of the products contained in the bottle by clearly demonstrating the presence to two distinct commodities in the single bottle.
  • first bottle half 12 and second bottle half 14 each have two ends, a bottom end 20 and a top end 22 .
  • the bottom end is closed and is typically flat or concave, providing a base for standing the bottle upright.

  • the housing incorporates a circumferential protrusion which mates with indentation 38 to eliminate the requirement for a separate securing ring.
  • the housing is adhesively bonded or ultrasonically welded to the disk in alternative embodiments.
  • FIG. 5 a A side sectional view of an alternative embodiment of the present invention is shown in FIG. 5 a wherein the cap mechanism incorporates two elements as with the embodiment previously described.

  • One example of such a bottle that is formed from a single part having a vertical septum separating two equal cavities is manufactured by Owens Illinois and is presently commercially available containing such commodities as drain clog removing chemicals and carpet cleaning solutions.
  • the Owens Illinois single-part bottle is manufactured by the extrusion blowmolding technique from a plastic resin such as high density polyethylene (HDPE), and the septum is formed by a molding technique known to those skilled in the art of blowmolding containers as a “pinch off”.

These channels align the lower element with the corresponding “D” shaped neck openings in the bottle.
  • the “D” shaped protrusions enter the neck of the bottle.
  • the snap engages and the bottle neck and septum collectively crush the soft underside sealing surface in the D-shaped channels of the lower element to create a tight seal against the top of the neck surface of the bottle and the top of the septum.
  • An upper element 58 is received within the cylindrical body of the lower element.
  • the upper element has a substantially circular face 65 which sealingly engages the upper surface of wall 54 in the lower element.

Rotation of the upper element to an intermediate position places the channel adjacent a blank portion of the wall while the circular face of the upper element seals the two orifices.
  • Lower element 52 again incorporates a substantially cylindrical body 62 which receives neck 36 a of outer bottle 42 .
  • a second cylindrical boss 64 depends from the wall 54 and receives neck 36 b of inner bottle 44 .

  • the upper element employs two channels 66 a and 66 b in communication with the outlet.
  • a first orifice in the wall communicates with the outer bottle while a second orifice in the wall communicates with the inner bottle.
  • Angular arrangement of the channels for alignment with the associated orifice upon rotation of the upper element to a predetermined position allows selection of a connection between the outlet and the contents of the inner bottle or the outer bottle. Again, rotation to a non-aligning position with both channels and orifices, provides for sealing of the orifices by the circular face of the upper element.
  • FIGS. 7 a - 7 d show upper element 58 in more detail.
  • two parallel flat sides 76 may be formed into the generally conically-shaped upper element for the embodiment shown.

  • Flat sides or protruding tabs are also useful to help the consumer overcome the sealing resistance of the upper cap as it statically compresses the seals surrounding the ports.
  • the amount of static seal compression may be adjusted to accommodate and prevent leakage of commodities of varying carbonation levels or to provide a “hard off” as will be described in greater detail subsequently.
  • Outlet 66 provides the selected contents to the user being provided by channel 66 a from the inner bottle when appropriately aligned for communication with the inner bottle and through channel 66 b from the outer bottle when properly aligned.

  • the orifices are positioned for access to the inner and outer bottles as previously discussed with respect to FIG. 6 with orifice 72 accessing contents of the inner bottle and orifice 74 accessing the contents of the outer bottle.
  • Inner passageway 66 a and outer passageway 66 b of upper element 58 align with orifaces 72 and 74 respectively when the upper element is rotated to the respective alignment position. When neither orifice is aligned, the cap seals both the inner and outer bottle.
  • the rotatable engagement between the upper and lower elements of the cap is accomplished by ridge 77 on the inner diameter of the lower element engaging groove 78 in the circumference of the upper element.

  • BACKGROUND
  • 1. Field of the Invention
  • This invention generally relates to liquids containers, and more specifically to a cap for selective communication with multiple chambers in a common container for different commodities.
  • 2. Description of the Related Art
  • Liquid storage containers have been provided in numerous sizes and shapes for various liquid commodities. The most ubiquitous containers are presently plastic and provide multiple sizes and shapes with mass production capability and recyclable materials.
  • In many endeavors, individuals use multiple commodities in combination. Sports enthusiasts are typically becoming aware of the benefits of combining the use of electrolyte replacing sports drinks with water for ultimate performance enhancement and refreshment. Children often desire to purchase more than a single flavor of soft drink or juices or combine a soft drink or juice with other liquid refreshment such as water or milk.
  • Beverage companies frequently launch new product flavors and have the need to inform customers that the new flavors are associated with their existing well-known brand and comprise part of their product portfolio. Currently, these companies are limited to arranging single-cavity bottles containing the new flavors in close proximity to other single-cavity bottles containing the well-known brand at the point of purchase.
  • Having multiple beverages or other commodities contained within a single bottle requires means for selective access to one or more of the commodities and a sealing arrangement for closure of the bottle. In the current state of the art, multiple chamber bottles are generally only dual-chambered and are limited to either having a single closure covering both openings with no ability to select between the openings, or two separate closures covering both openings with no common output or variable selection means.
  • It is therefore desirable to provide a cap and selection system for integrated containers having multiple cavities or chambers for storage of different commodities. It is further desirable that such a cap be easily manufactured and applicable to various multiple chamber bottle configurations.
  • SUMMARY OF THE INVENTION
  • A source selecting cap and closure for multiple cavity bottles incorporates a first element sealingly engaging a first opening in a first cavity of a bottle and a second opening in a second cavity of the bottle. A second element is movably engaged by the first element and provides an outlet and means connected to the outlet for selectively communicating with the first cavity of the bottle in a first position and communicating with the second cavity of the bottle in a second position.
  • In one embodiment, the first element includes a wall covering the first and second opening, the wall including a first orifice in communication with the first cavity and a second orifice in communication with the second cavity. The second element incorporates a sealing face adjacently opposed to the wall and at least one channel in the second element extending from the outlet to an aperture in the sealing face, said aperture in alignment with the first orifice in said first position and in alignment with the second orifice in a second position for selectively communicating with the cavities.
  • In an alternative embodiment, the first element incorporates a bore with a first channel communicating with the first opening and terminating at a first orifice in the bore and a second channel communicating with the second opening and terminating at a second orifice in the bore. The second element incorporates a hollow cylindrical stem, a portion of which is closely received within the bore with the outlet located adjacent a first end of the stem. An aperture in a side wall of the stem distal the outlet and aligned with the first orifice in a first angular orientation of the stem and with the second orifice in a second angular orientation of the stem provides the selective communication with the cavities and rotating the stem establishes the first and second angular orientation.

  • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the drawings, FIG. 1 is an isometric view of a bottle 10 incorporating the multiple chambers with which the present invention is employed. For the embodiment shown, elements or moieties of a combination forming the invention are a first bottle half 12, and second bottle half 14 that are engaged to form the completed bottle having two separate cavities for storage and dispensing of two separate liquids.
  • An exploded isometric view of the bottle for the embodiment described is shown in FIG. 2. Each half has an outer surface 16 and mating surface 18. The outer surface of the first bottle half, and second bottle half may be of any shape, but the example shown have a generally cylindrical outer surface. The mating surfaces of each bottle half are formed as complimentary shapes, allowing the bottle halves to adjacently seat together in a side-by-side relationship.
  • In the embodiment shown, mating surface 18 of each bottle half forms a generally flat plane with a helical twist or, alternatively described, the helical mating surface has a planar cross section. The flat shape is preferred because it allows both bottle halves to be manufactured as the same part. Alternately, the mating surface may be shapes other than flat, such as concave and convex and may have male and female joining features, but any such features or shapes that are not symmetrical require that the bottle halves are formed as two separate parts from different molds. When the bottle halves are seated together, their mating surfaces sit adjacently together along the flat twisted plane that is formed at the angle of helical rotation. This helical shaping, particularly if 180° of twist or greater, allows the contents of the two cavities of the combined bottle to be viewed from any aspect thereby enhancing the marketability of the products contained in the bottle by clearly demonstrating the presence to two distinct commodities in the single bottle.
  • As shown in the drawings, first bottle half 12 and second bottle half 14 each have two ends, a bottom end 20 and a top end 22. The bottom end is closed and is typically flat or concave, providing a base for standing the bottle upright. The top end of each bottle half has an opening 24 a and 24 b for individually dispensing the contents of each bottle half. While the opening can be any shape, the opening shown is “D” shaped. Top portion 22 may also have a threaded or unthreaded surface for receiving a cap mechanism for sealing the opening, as will be described in greater detail subsequently.
  • The combined bottle can incorporate more than two bottle cavities, but the embodiments shown for this embodiment provide two cavities. The separate cavities of the combined bottle can be used to contain any substance that a person practicing the invention desires. One anticipated embodiment is as a beverage container holding, for example, an electrolyte replacing sports drink in one cavity and water in the second cavity.
  • Since both first bottle half 12 and second bottle half 14 are separate containers, each capable of holding a liquid and keeping the liquid sealed and separate from the contents of the other bottle half, there is a separate opening, 24 a and 24 b, in each cavity. In the embodiment shown, the opening of each cavity is generally “D” shaped and when first bottle half 12 and second bottle half 14 are intertwined together, the combination of opening 24 a from first bottle half 12 and opening 24 b from second bottle half 14 creates a generally cylindrical threaded or unthreaded neck.
  • FIGS. 3 a through 3 d demonstrate alternative connection and cavity configurations for various embodiments of bottles with which the present invention is employed. FIGS. 3 a and 3 b show a combined bottle incorporating two individually sealable bottle halves 26 and 28 with a mating surface 30. The two cavities need not be constructed as equally proportioned halves, they may be constructed in unequal halves as shown by large left half 26′ and small right half 28′ demonstrated in FIG. 3 c. The threads or snap feature of the cap hold both halves together and seal their contents. For additional strength beyond that which is provided by the application of a threaded or snap-on closure to secure the bottle halves together, the embodiment of FIG. 3 a may incorporate an optional flange 32 over which a collar 34 (shown in section) is forced to circumferentially engage the neck 36. An alternative embodiment of an upper engagement is shown in FIG. 4 wherein an optional indentation 38 is provided in the circumference of the neck in which a ring 40 (shown in section) is engaged. FIG. 3 d shows a coaxial bottle within a bottle arrangement wherein an outer bottle 42 receives and surrounds an inner bottle 44.
  • FIG. 4 shows a cap mechanism 50 according to the present invention. A substantially cylindrical lower element 52 is received over the protruding neck 36 of the bottle halves. A wall 54 seals the lower element with orifices 56 a and 56 b positioned over the openings in the respective bottle halves. A rotatable upper element 58 is received in the cylindrical body of the lower element and incorporates a channel 60 which is positionable over orifice 56 a for communication with the cavity of the first bottle half or over orifice 56 b for communication with the cavity of the second bottle half or intermediate the two apertures to re-seal the bottle. In alternative embodiments, the housing incorporates a circumferential protrusion which mates with indentation 38 to eliminate the requirement for a separate securing ring. The housing is adhesively bonded or ultrasonically welded to the disk in alternative embodiments.
  • A side sectional view of an alternative embodiment of the present invention is shown in FIG. 5 a wherein the cap mechanism incorporates two elements as with the embodiment previously described. An upper element 52 is rotatably supported in a lower element 58. The lower element incorporates a substantially cylindrical body 62 with a sealing wall 54 and is secured to the dual cavity bottle, in the embodiment shown by an engagement protrusion snap 39 in the inner circumference of the body snapped into position over a mating female engagement indentation 38 in the circumference of the neck 36 of the bottle. One example of such a bottle that is formed from a single part having a vertical septum separating two equal cavities is manufactured by Owens Illinois and is presently commercially available containing such commodities as drain clog removing chemicals and carpet cleaning solutions. The Owens Illinois single-part bottle is manufactured by the extrusion blowmolding technique from a plastic resin such as high density polyethylene (HDPE), and the septum is formed by a molding technique known to those skilled in the art of blowmolding containers as a “pinch off”. An example of this single-part bottle with a vertical septum is shown in partial cross section in FIG. 5 a. The embodiment of the single-part bottle with a septum or common wall 30 provides sealing engagement between the wall and opposed D-shaped channels create protrusions 63 (best seen in the perspective view of FIG. 5 b) extending diametrically across the bottom of the lower element. These channels align the lower element with the corresponding “D” shaped neck openings in the bottle. During assembly the “D” shaped protrusions enter the neck of the bottle. After lowering the lower element down into the neck slightly, the snap engages and the bottle neck and septum collectively crush the soft underside sealing surface in the D-shaped channels of the lower element to create a tight seal against the top of the neck surface of the bottle and the top of the septum.
  • An upper element 58 is received within the cylindrical body of the lower element. The upper element has a substantially circular face 65 which sealingly engages the upper surface of wall 54 in the lower element. The wall in the lower element incorporates a first orifice 56 a communicating with opening 24 a of the first cavity of the bottle and a second orifice 56 b communicating with opening 24 b of the second cavity of the bottle. A channel 60 extending through the upper element to a dispensing opening 66 is positionable over a selected one of the orifices by rotation of the upper element. Rotation of the upper element to an intermediate position places the channel adjacent a blank portion of the wall while the circular face of the upper element seals the two orifices.
  • For bottles with a configuration similar to the coaxial bottle in bottle of FIG. 3 d, the cap mechanism shown in FIG. 6 is employed. Lower element 52 again incorporates a substantially cylindrical body 62 which receives neck 36 a of outer bottle 42. A second cylindrical boss 64 depends from the wall 54 and receives neck 36 b of inner bottle 44. For the embodiment shown, the coaxial arrangement of the inner and outer bottles allows threaded engagement between mating moieties in the necks and the cylindrical body and boss. As in the embodiment described previously, a snap engagement is employed in alternative embodiments of the coaxial bottle arrangement.
  • The upper element employs two channels 66 a and 66 b in communication with the outlet. As will be described with respect to FIGS. 8 a and 8 b, a first orifice in the wall communicates with the outer bottle while a second orifice in the wall communicates with the inner bottle. Angular arrangement of the channels for alignment with the associated orifice upon rotation of the upper element to a predetermined position allows selection of a connection between the outlet and the contents of the inner bottle or the outer bottle. Again, rotation to a non-aligning position with both channels and orifices, provides for sealing of the orifices by the circular face of the upper element.
  • FIGS. 7 a-7 d show upper element 58 in more detail. To facilitate the rotation of the upper element, two parallel flat sides 76 may be formed into the generally conically-shaped upper element for the embodiment shown. The flat sides of the upper element are grasped using the fingers in order to more easily rotate the cap between the three (or more) desired positions for example off position, drinking the beverage in the outer bottle, drinking the beverage in the inner bottle and mixing the contents of both. Flat sides or protruding tabs are also useful to help the consumer overcome the sealing resistance of the upper cap as it statically compresses the seals surrounding the ports. The amount of static seal compression may be adjusted to accommodate and prevent leakage of commodities of varying carbonation levels or to provide a “hard off” as will be described in greater detail subsequently. Outlet 66 provides the selected contents to the user being provided by channel 66 a from the inner bottle when appropriately aligned for communication with the inner bottle and through channel 66 b from the outer bottle when properly aligned.
  • FIGS. 8 a and 8 b are top view and side section view taken through plane 8 b-8 b that show lower element 52 in more detail. It is apparent from the top view that the embodiment shown features two cylindrically-shaped orifices, inner orifice 72 and outer orifice 74. The orifices may be any shape desired for practicing the invention as will be described in greater detail subsequently. The orifices are positioned for access to the inner and outer bottles as previously discussed with respect to FIG. 6 with orifice 72 accessing contents of the inner bottle and orifice 74 accessing the contents of the outer bottle. Inner passageway 66 a and outer passageway 66 b of upper element 58 align with orifaces 72 and 74 respectively when the upper element is rotated to the respective alignment position. When neither orifice is aligned, the cap seals both the inner and outer bottle.
  • For the embodiment shown in FIGS. 7 a-7 d and 8 a and 8 b, the rotatable engagement between the upper and lower elements of the cap is accomplished by ridge 77 on the inner diameter of the lower element engaging groove 78 in the circumference of the upper element. The lower element is secured to the neck of the inner bottle by threads 80 and secured to the outer bottle with threads 82. In alternative embodiments, a snap fit or alternative engagement mechanism is employed as previously described. Referring to FIGS. 7 a and 8 a, an arrow 73(d) or other position indicating mark can be used on intermediate cap 16 to align with a corresponding mark 73(a), 73(b) or 73(c) on upper cap 18 to indicate to the user which position the cap is in. In the example shown in the drawings, a high energy drink is contained in the inner bottle with the appropriate arrow 73(b) labeled “ENERGY”. The outer bottle contains water and label 73(a) provides the appropriate reference. The “off” position is identified by label 73(c) (not marked as off in the drawing). In an alternate embodiment, a detent feature is used to allow upper cap 18 to “click” into place as it is rotated relative to intermediate cap 16 into positions such as 1) off, 2) inner bottle contents, and 3) outer bottle contents.
  • The embodiment of the invention disclosed in FIGS. 7 a-7 d and 8 a and 8 b is easily optimized for molding using standard injection molding techniques. For example, groove 78 in FIGS. 7 b-7 d represents an “undercut” in an injection mold, however, it is a common practice to those skilled in the art of injection molding plastics to forcefully eject upper element 58 from an injection mold cavity with an ejector boss or elector sleeve relying on the elasticity and resilience of the molded plastic to flex off the mold without damaging or destroying the geometry of groove 78. Similarly, threads 80 and 82 of lower element 52 represent undercuts in an injection mold, however it is a common practice to those skilled in the art of injection molding bottle closures to form such threads as “strippable threads” and forcefully strip them off of the mold core with an ejector boss or ejector sleeve relying on the elasticity and resilience of the molded plastic to flex off the mold core without damaging or destroying the geometry of threads 80 and 82. The techniques described above allow for the construction of less expensive and simpler molds than molds containing unscrewing features, or collapsible cores.
  • FIGS. 9 a-9 c provide one such optimized embodiment. As shown in FIG. 9 a in side section the channels for communication with the outlet are created by a dumbbell shaped key slot 90 in communication with a bore 92 extending downward from the outlet 66. As shown in FIG. 9 b the key slot is incorporated in a web 94 extending diametrically across the upper element creating open volume between the web and the cylindrical body. These “core outs” eliminate much of the sealing surface of the upper element disclosed in prior embodiments. The cylindrical openings of the key slot and the outlet bore are created within the web. This configuration provides a substantially constant wall thickness for the entire molded part. To maintain separation of the inlet ports for selective communication with the two orifices in the lower element a sealing disk 96, best seen in FIG. 9 c, provides an inner aperture 98 and an outer aperture 100 for alignment with the inner and outer orifices in the lower element upon proper rotation of the upper element with respect to the lower element. As shown in FIGS. 9 a and 9 b, the disk seals against the facing surface 102 of the molded walls of the upper element with the apertures (72, 74) aligned with the inner and outer circular portions (104 and 106) of the key slot. Forming the key slot directly into the flat disk potentially creates edges at the transition of the key way into the two round orifices that may hang up on the soft seals or o-rings surrounding the ports. The use of two unconnected round holes or kidney-bean shaped ports in the flat disk as shown in the embodiments and described below avoids this issue. For the embodiment shown, the sealing disk is mechanically attached to the upper element using resilient tabs 108 received in mating slots 110. Alternatively, the disk is adhesively bonded or ultrasonically welded to the upper element. Coupling of the upper and lower element is accomplished using a rib and groove arrangement as previously described or a central barb 97 extending from the mating wall of the lower element through apertures in the disk and web as shown in FIG. 9 a.
  • The disk has sufficient thickness and flatness to maintain a rigid planar sealing surface 112 which interfaces with the wall of the lower element. The wall can incorporate multiple orifices for creating selective communication with either one or both of the containers created by the bottle as shown in FIG. 9 d. The orifices in the wall are shown in phantom with the apertures in the disk shown in full line form. In a first position 120 with the upper element rotated to place the apertures in the right semicircle of the wall, nominally on the horizontal axis at 0 degrees, the apertures are adjacent blank portions of the wall and the bottle is sealed as indicated by two X marks. In a second position 122 with the upper element rotated to place the apertures in a 90 degree position, the inner orifice 72 is aligned with the inner aperture providing communication with the contents of the inner bottle. In a third position 124 with the upper element rotated to place the apertures in a 180 degree position, the outer orifice 74 is aligned with the outer aperture providing communication with the contents of the outer bottle. Finally, with the upper element rotated to a forth position 126 at 270 degrees, two orifices 72 a and 74 a are aligned with the inner and outer apertures to allow access to the contents of both containers simultaneously. The outer orifice 74 a shown in the figure may be smaller in diameter than the outer orifice 74 providing less flow volume for the contents of the outer bottle in the mixed position than in the single flow condition at position 124. Additional pairs of orifices with varying diameters are oriented at different rotation angles in alternative embodiments to provide various mixtures of the contents of the inner and outer bottle. Alternatively, slots of varying width are placed under the arc of the inner and outer orifice for flow variation. Additionally, while circular orifices and apertures are shown in the drawings, oval, crescent or other alternative shaped openings for increased flow capacity are employed in alternative embodiments.
  • The features of the described embodiment are seen in perspective views of the various elements and assemblies in FIGS. 9 e-9 j. The lower perspective view of FIG. 9 e shows the hog outs and wall thicknesses of the upper element with keyway 90 and inner and outer circular portions 104 and 106 forming the flow passages. Outlet bore 92 and web 94 are also displayed as well as engagement slot 110 for the locking tabs on the disk. The upper exploded perspective of FIG. 9 f shows molded case of upper element 58 in relation to disk 96. Engagement tabs 108 protrude from the disk for engagement in slots 110 as previously described. Apertures 98 and 100 are surrounded by an elevated lip 107 which is sealingly received in the female circular and joining portions of the keyway.
  • Similarly, the bottom perspective of lower element 52 as seen in FIG. 9 g, shows ports 72 and 74 and the associated body 62 and boss 64 receiving the outer and inner bottles respectively while the upper perspective of FIG. 9 h shows the ports in relation to the flat receiving wall engaging the disk in the upper element. Detents 109 which receive dimple 111 on the upper element (best seen in FIG. 9 f) provide positive engagement at the rotated positions for selection of the inner and outer bottle contents and the “off” position.
  • FIG. 9 i shows a lower perspective exploded view of the upper element with the disk in place prior to insertion into the lower element while FIG. 9 j shows an upper perspective of the fully assembled cap. A plurality of vertical raised ribs are used on the outer diameter of the lower element 52, as shown in the drawings, and are engaged by a capping chuck having a corresponding set of vertical female ribs for use in screwing the assembled cap shown in FIG. 9 j onto an inner bottle during a first step, and later onto an outer bottle during a second step of the filling process for a coaxial dual cavity bottle as shown in FIG. 6.
  • Additional features for sealing of the disk and orifices in the wall are employed in alternative embodiments as shown in FIGS. 10 a-10 c. An o-ring 130 inserted in a relief 132 surrounding the orifice 72 or 74 provides a reliable mechanical seal as shown in FIG. 10 a. A first alternative is shown in FIG. 10 b where a molded circular lip 134 surrounds the orifice. The lip may be formed facing towards the port and with such geometry that the application of increased pressure from the inside of the bottle will cause a tighter seal and prevent leakage. In certain embodiments, a one step molding process is employed for the lip seal while in alternative embodiments, a two step co-injection molding process is employed to provide a softer durometer material in the lip seal than in the remainder of the wall. FIG. 10 c shows a molded circular ridge seal 136 employing multiple teeth of varying height. As for the lip seal, a two step process can be employed to provide a different durometer in the seal element than in the remainder of the wall.
  • As shown in FIGS. 10 d and 10 e, a “hard shutoff” is incorporated in certain embodiments of the present invention for shipment of the filled bottle to assure no leakage. As shown in FIG. 10 d, disk 96 incorporates depending plateaus 133 which hyper-compresses o-ring 130 to assure sealing over the associated orifice 72 or 74. When the cap is initially rotated from the “hard off” position by the user to open the container for flow from one bottle as shown in FIG. 10 e, the plateau is rotated off the o-ring which assumes its normal sealing shape engaging the bottom of the disk. The hard off position for the exemplary embodiments previously described with respect to FIGS. 7 a-7 d and 8 a and 8 b above could be placed opposite the “off” indicator with no marking.
  • While the rotating closure mechanism provides closure for the separate cavities of the bottle, an alternative embodiment providing a positive closure on the outlet of the cap mechanism is shown in FIG. 11. The outlet incorporates an extended neck 140 which is threaded to receive a mating threaded cap 142. This allows the cap mechanism to remain aligned with one of the content orifices but be sealed at the outlet. In other alternative embodiments, the threaded cap is replaced by a standard “sports top” sliding closure.
  • FIG. 12 shows an alternative embodiment of the present invention employing a vertical hollow rotatable cylindrical stem 150 received in a cylindrical bore 152 in a body 154 of the cap mechanism. An input port 156 oriented on a side wall of the stem is selectively positionable at a first channel 158 in the body communicating with a first cavity, in the embodiment shown an inner bottle 44, or at a second channel 160 communicating with a second cavity, the outer bottle 42 for the embodiment shown. A first angled o-ring 162 mounted on a receiving groove 164 on the stem engages the wall of the bore to seal the input port while a horizontal o-ring 166 mounted in a second groove seals the stem to the bore. Paddle tabs 168 attached to the shaft facilitate rotation of the shaft for alignment of the input port. The stem is terminated at an end opposite the input port with one or more outlet ports 170 to communicate the selected commodity to the user. A closure mechanism, such as a sports top 172 as shown in the figure, or a threaded sealing cap in alternative embodiments, is provided to seal the outlet port. In alternative embodiments, the stem is axially movable to align the port with axially displaced channels for selection of the desired bottle contents.
  • FIGS. 13 a-13 c demonstrate a refined design for the embodiment of the invention disclosed in FIG. 12 in which body 154 is molded to include threaded cylindrical receiver 62 for the outer bottle and threaded boss 64 for the inner bottle with channels 158 and 160 for flow communication with the contents of the bottles. The angled o-ring of the embodiment of FIG.12 is replaced with triangular profile round seals 174 and 176 which encompass the outlets of channels 158 and 160 respectively. Stem 150 is received within bore 152 in the body. Seals 174 and 176 sealingly engage the stem preventing flow from either bottle unless port 156 is aligned with one of the channels.
  • Stem 150 is integrated into a shell 177 having sides received in an upwardly oriented mating boss 178 surrounding body 158. As describe in previous embodiments, a groove 76 in the mating boss receives a rib 78 on the shell for rotatable engagement, restraining the shell and stem in the body. Detents 109 in the mating boss receive and engage a dimple 111 in the shell for positive positioning of the shell and stem with the port aligned with one of the channels or an intermediate “off” position as shown in FIG. 13 b.
  • In alternative embodiments two apertures on the stem at different elevations are alignable at predetermined rotational angles with the channels which are also arranged to terminate at different elevations and at different angles of rotation not horizontally opposed as shown in the drawings. In this configuration, plateaus added to the stem are also employed as previously described with respect to FIGS. 10 d and 10 e to provide a “hard off” position for the stem.
  • Additional features to facilitate rotation of the cap mechanism such as the tabs employed in the embodiment described with respect to FIG. 12 are also applicable in certain embodiments of the invention such as that shown in FIG. 14. Upper element 58 of the cap mechanism employs an extended tab 180 to provide additional leverage in rotating the upper element within the lower element for alignment of the respective orifice and aperture to select the desired commodity.
  • Alternative container arrangements for separate cavities or commodity chambers are also accommodated by the present invention. As shown in FIGS. 15 a and 15 b, a cap mechanism having a rotatable upper element 58 and a lower element 52 secures a double bottle having two separate necks, 36 c, and 36 d. The lower element is elliptical and employs engagement elements 182 in the inner circumference of receptacles 184 a and 184 b snapped into position over mating engagement elements 186 in the circumference of the necks 36 c and 36 d of the bottle. Channels 57 a and 57 b in the lower element communicate with orifices 56 a and 56 b for alignment with one or channels 60 in the upper element which communicate with an outlet 66. Multiple orifices and/or channels are employed in alternative embodiments for alternate selection and mixing of the commodities in the bottle chambers as previously described with respect to FIG. 9 d.
  • Having now described the invention in detail as required by the patent statutes, those skilled in the art will recognize modifications and substitutions to the specific embodiments disclosed herein. Such modifications are within the scope and intent of the present invention as defined in the following claims.
