In other words, by turning a knob at the base of the cartridge, the toothpaste stored in the cartridge is discharged from the end of the cartridge and travels to the brushing head of the toothbrush (and expelled into the bristles). Within the cartridge, a pusher plate travels in the direction of the brushing head to propel the toothpaste to the brushing head, in response to turning of the knob, as discussed below with respect to the drawings. When the toothpaste has been consumed and depleted within the cartridge, the tube or cartridge can be replaced, or refilled with toothpaste.
  • For the user, the product ultimately combines a toothbrush and toothpaste in a single combined unit. The improved oral care product may be of particular appeal to users who desire the convenience of a single assembly for brushing teeth, such as travelers, patrons of clubs, and members of the labor force including members of the military, for example, or anyone in the general public. The toothbrush and cartridge may be a wide array of sizes and colors, and appropriate for adults and children. Further, the toothpaste in the cartridge may be a variety of types and flavors. Moreover, the bristles at the head of the toothbrush may be of various hardness, angles, and configurations. Further, the brushing head may be angled to facilitate better access to the back teeth, for instance. In addition, the handle of the toothbrush may be contoured and/or have raised portions to facilitate grasping the toothbrush. As for materials, the toothbrush may be constructed of plastic such as polyvinyl chloride, or rubber, or other materials. The bristles may be various plastics or fibers, such an extruded nylon.
  • In all, the product provides for not having to employ a toothbrush and tube of toothpaste separately. It may simplify the tooth-brushing activity while in the home or away from home. Advantageous features may include convenience, self-contained design, portability, compact size, and the like. In embodiments, the product may provide for not having to carry a full-sized toothbrush and tube of toothpaste separately. Moreover, the product may address certain untidy features of using a separate tube of toothpaste. The product may also reduce chances of forgetting to pack oral hygiene products, and may also take less space in a suitcase or overnight bag, for example.
  • As explained more below, the toothbrush and paste cartridge are configured such that the disposable cartridge fits inside a cavity or compartment in the handle of the toothbrush, and is removable from the reusable toothbrush. The compartment has a door (e.g., hinged) in the sidewall of the toothbrush handle. In certain embodiments, the door clicks in place in the closed position and secures the received paste cartridge such that the cartridge body does not rotate when the dispensing knob of the cartridge is turned. Of course, as indicated below, other features may be incorporated to secure the cartridge and preclude undesired rotation of the cartridge.
  • As depicted in the drawings, the cartridge has a piston, a pusher or paste plate secured to the piston, and a knob to turn the piston to drive the paste plate forward (and thus push the toothpaste into the bristles of the toothbrush). The knob may generally be located at the base of the toothpaste cartridge. Moreover, the compartment door on the handle of the toothbrush may have an opening to receive the knob, such that the knob is accessible to a user without opening the door on the toothbrush.
  • Further, it should be noted that turning or rotation of the knob may be manual (by hand) or automatic (mechanized via a motor). Furthermore, a cavity at the bottom end or portion of the toothbrush handle may house the motor and associated battery. The battery may be a cylindrical battery, flat cell battery, and so forth. In alternate embodiments, the motor may also provide for vibration of the head/bristles of the toothbrush
  • Moreover, a gripping portion of the toothbrush including ridges, or bumps, or the like, may facilitate holding the handle of the toothbrush. Optionally, curved portions of the handle may be included to facilitate handling of the toothbrush and/or insertion of the head and bristles of the toothbrush into the mouth to brush the teeth.
  • Referring now to the drawings, FIG. 1 depicts a toothbrush assembly 10 including a toothbrush 12 having an installed toothpaste cartridge 14. For clarity, the toothpaste cartridge 14 is depicted separately. Moreover, it should be emphasized that the depicted shape and form of the toothbrush 12 and cartridge 14 are only exemplary, and the toothbrush 12 and cartridge may be of other shapes, forms, and geometries.
  • In the illustrated embodiment, the toothbrush 12 has a handle 16 and a head 18 having bristles 20. The cartridge 14 has a cylindrical housing or body 22 (having a wall 23), a knob 24 at the base 26, and a piston 28 extending through an end plate 30 to secure the piston 28 at an end face 35 of the cartridge 14. Discharge holes 32 are included in the end plate 30 for the toothpaste (residing in the cartridge 14) to exit the cartridge 14.
  • When the cartridge 14 is installed in the toothbrush 12, the knob 24 of the cartridge 14 extends through an aperture or opening 34 (e.g., gap, notch, etc.) in the handle 16 the toothbrush 12 so that the user has ready access to the knob 24. The opening 34 may be recessed to adequately expose the knob 24 to the user.
  • Further, a cavity (not shown) inside the base 36 of the handle 16 may be configured for housing a motor (not shown), for example, used to turn the knob 24. Of course, in the illustrated embodiment, the knob may be manually turned by hand. Moreover, raised portions 37 may be disposed on the handle 16 to facilitate gripping of the toothbrush 12. The raised portions 37 may be raised surfaces, bumps, ridges, and so on.
  • Additionally, a brand name 38 or other text or graphics, may be provided on the handle 16 or head 18 of the toothbrush 12. Lastly, as discussed below, the handle 16 of the toothbrush 12 includes a door 42 that opens so the toothbrush 12 can receive the toothpaste cartridge 24.
  • FIG. 2 depicts the end face 35 of the substantially cylindrical cartridge 14 of FIG. 1, and showing the substantially circular end plate 30. The tip or end of the piston 28 extends through an opening 39 of the end plate 30. As mentioned, the discharge holes 32 provide an exit for the toothpaste stored in the cartridge 14. While the discharge holes 32 are depicted as square or rectangular, the discharge holes 32 may be other shapes or geometries, such as other straight geometries, curved, circular, and so on.
  • FIG. 2A and FIG. 2B depict alternate shapes for the overall cartridge 14 in showing an end face 35A as oval in FIG. 2A, and an end face 35B as square in FIG. 2B. Such oval or square shapes depicted in FIG. 2A and FIG. 2B, respectively, of the end plate 30 and cylinder 14, instead of a cylindrical shape of the cylinder depicted in FIG. 1 and FIG. 2, may be beneficial. For example, in certain embodiments, the oval or square/rectangular shapes may better facilitate securing the cylinder 14 to preclude undesirable rotation of the overall cylinder 14 (installed in the handle 16 of the toothbrush 12) when the knob 24 is turned to dispense the toothpaste. Of course, the internals of the toothbrush 12 may be configured to accommodate such alternate oval and square geometries.
  • Internals (not depicted) of the toothbrush 12 and may also have extensions or other elements to facilitate securing of the cartridge 14. Likewise, internals of the toothbrush 12 or on the cartridge 14 may include seals, baffles, gaskets, and so on, to prevent or reduce backflow of discharged toothpaste, for example, into the handle of the toothbrush 12 away from the head 18.
  • FIG. 3 depicts the toothbrush 12 with the door 42 in the open position, and the toothbrush 12 in the empty position without the cartridge 14 but ready to receive the cartridge 14. In operation, the door 42 of the handle 16 may be opened to receive the cartridge 14 into cavity or compartment 44 of the handle 16. Internals (not depicted) may be disposed at the base 43 of compartment 44 to support the received cartridge 14. FIG. 4 also depicts the toothbrush 12 with the door 42 in the open position but with the cartridge 14 inserted into the toothbrush 12. The toothpaste cartridge 14 may optionally have a support extension 45 below the knob 24, or other configurations.
  • The door 42 may be hinged via hinges 46 at one or more places with the handle 16. When closed, the door 42 may be “clicked” closed with a male coupling 48 on the door 36 and a female coupling 50 on the handle 16 (or vice versa), for example. Thus, the door 42 may be coupled with the handle 16 and clicked in the closed position with the handle 16. The door 42 in the closed position facilitates securing of the installed cartridge 14 in place inside the handle 16 of the toothbrush 12.
  • In alternate embodiments, the handle 42 may be positioned elsewhere on the handle 16 of the toothbrush 12. In one example, a base 36 portion is removable (e.g., screwed, clamped, clicked, etc.) and the cartridge 14 to be inserted through that end of the handle 16 into the cavity or compartment 44.
  • FIG. 5 is a diagrammatical representation of the cartridge 14 showing the inside of the toothpaste cartridge 14. Similarly, FIG. 6 is a diagrammatical representation of the toothbrush 12 showing the internal toothpaste flow path. In FIG. 6, the toothpaste cartridge 14 is disposed in the toothbrush 12. As depicted in both FIG. 5 and FIG. 6, the toothpaste cartridge 14 has an internal push plate 52 that supports the toothpaste 54 residing in the interior 51 of the cartridge 14. The push plate 52 may be labeled a paste plate, support plate, and so on, and may be threaded at the mating surface to the piston 28.
  • In operation, the knob 24 may be turned (manually or via a motor) to rotate the threaded (or grooved) piston 28 (or rod, bolt, etc.) to move the paste plate 52 forward to transfer and push the toothpaste 54 through the holes 32 of the end plate 32 into the internal conduit 56 of the toothbrush 12. The toothpaste 54 flows through the conduit 56 and exits a hole or opening 58 into the bristles 20. In other words, in the illustrated embodiment the conduit 56 terminates at the head 18 and bristles 20, and the conduit 56 discharge is the hole or opening 58 in the head 18 at the bristles 20. Moreover, the conduit 56 may include a reducer such as a reducing fork 60 that receives the toothpaste 54 from the holes 32 of the end plate 30 of the toothpaste cartridge 14. Additionally, it should be apparent that in alternate embodiments, the conduit 56 may branch into multiple conduits 56 and exit through multiple openings 58 to increase distribution of the paste 54 into the bristles 20. Lastly, residual toothpaste may remain in the conduit 56 when a new full toothpaste cartridge 14 is installed to replace an old depleted toothpaste cartridge 14. On the hand, the conduit 56 may be cleaned and any residual toothpaste removed.
  • FIG. 7 depicts a method 100 of using a toothbrush assembly, the method including opening (block 102) a hinged door on a side of a handle of a reusable toothbrush to reveal a compartment in the handle of the toothbrush. The method includes inserting (block 104) a disposable toothpaste cartridge into the compartment, wherein the toothpaste cartridge comprises a body and a cavity to store toothpaste. Additionally, the method includes closing (block 106) the hinged door to snap the door shut with the side of the handle to secure the disposable toothpaste cartridge in place in the compartment of the toothbrush. Furthermore, the method includes turning (block 108) a knob at the base of the cartridge to rotate a piston in the cartridge to move a paste plate of the cartridge forward to dispense toothpaste from the cartridge into a conduit of the reusable toothbrush to bristles of a head of the reusable toothbrush, wherein the knob extends through an opening of the door to outside of the handle of the toothbrush for access to a user. Also, the method includes gripping (block 110) the handle of the toothbrush via a raised portion on the handle, and brushing (block 112) teeth with the toothbrush and toothpaste. The raised portion may include ridges or bumps, or a combination thereof.
  • In sum, the present techniques in a first example may include a toothbrush assembly including a toothbrush having: a handle for holding the toothbrush and having a compartment to receive a toothpaste cartridge; a head having bristles to brush teeth; a door covering an opening of the compartment, wherein the door in an open position receives the toothpaste cartridge into the compartment, and the door in a closed position secures the toothpaste cartridge received in the compartment; and a conduit running from the compartment to the head, the conduit to facilitate delivery of the toothpaste from the cartridge in the compartment to the head and the bristles.
