Definitions
- the present invention is related to the field of personal hygiene, to the field of oral hygiene, and more specifically, to a toothbrush which stores and/or dispenses toothpaste.
- Proper oral hygiene is considered paramount in the development and maintenance of a strong and healthy mouth.
- Professional dental care, regular cleanings, and proper and effective teeth cleaning removes the sticky, colorless bacteria-produced biofilm known as plaque. Removal of plaque through proper cleaning prevents formation of cavities and periodontal diseases. Failure to remove plaque on a regular basis results in the build-up and thickening of the biofilm and increased risk of developing dental diseases such as gingivitis. Left untreated, gingivitis can result in the more advanced disease of periodontitis. Progression of periodontitis ultimately results in tooth loss.
- Brushing one's teeth is a fundamental technique considered as an effective daily treatment to maintain healthy teeth and gums. While numerous commercially available toothpastes/gels exist, all such products are fundamentally designed to aid in maintaining healthy teeth and gums. Most toothpastes/gels contain antibacterial ingredients and abrasives for removing dental bacterial plaque. In addition, special ingredients may also be included which help clean and polish the teeth, and remove stains over time. Finally, toothpastes/gels may further enhance oral hygiene as they help to freshen the user's breath, leaving his/her mouth with a clean feeling.
- toothbrushes contain the basic parts of a handle and brush head portions. Toothpaste is added to the brush head region and the brush is then articulated in an acceptable and useful manner.
- Traditional means of dispensing toothpaste to a toothbrush includes aligning the toothbrush head and bristles with a toothpaste bottle or tube. Once aligned, the user simply squeezes the bottle, forcing the toothpaste out and onto the toothbrush head.
- Electronic toothpaste dispensing devices are known in the art. These devices are independent units designed to dispense toothpaste onto an individual's toothbrush. Separate dispensing units, however, have the disadvantage of taking up space in the bathroom, and require the steps of aligning the toothbrush head with the dispensing portion.
- the present invention provides an improved device for maintaining oral hygiene by providing for a quick, easy, and convenient mechanism for brushing teeth.
- the present invention is directed to a toothbrush, and more particularly to a toothbrush that can store toothpaste within the body of the handle.
- the toothbrush in accordance with the present invention is also designed to dispense the stored toothpaste directly onto the brushing head, thereby eliminating the need to have a separate toothpaste tube as part of an individual's oral hygiene routine.
- the toothbrush comprises a handle and brushing head.
- the handle contains a toothpaste storage area fluidly coupled to one or more toothpaste dispensing members located within the brushing head.
- the toothbrush having internal storage and dispensing capability comprises a handle portion having a first end, a second end and a main body separating the first and the second end.
- the main body has a plurality of surfaces interconnected to form a handle interior region.
- the handle interior region is sized and shaped to receive and store a material therein.
- the toothbrush also comprises a brush head portion fluidly connected to the handle portion.
- the brush head portion has a first brush head end, a second brush head end, and a brush head body separating the first brush head end and the second brush head end.
- the brush head body has a plurality of surfaces arranged about a space thereby forming a brush head interior region, at least one fluid dispensing component, and at least one tooth cleaning member.

Alternatively, thehandle 12 and the brushinghead 14 may be formed separately and secured together independently. The brushinghead 14 contains a plurality of cleaning or scrubbing members, illustrated herein as rows of toothbrush bristles 28. Thebrush head 14 is fluidly connected to thehandle 12 so that a fluid material, such as a liquid or gel, can be transported from a portion of thehandle 12 to thebrush head 14. As used herein, the term fluid may be defined as a nearly incompressible fluid that conforms to the shape of its container but retains a constant or nearly constant volume independent of pressure. In addition, liquid may be defined as a fluid or a substance, like a paste or gel, which behaves like a solid until a substantially large force or stress is applied, at which point it flows like a fluid. - Referring to
FIG. 2A , a cross sectional view of an illustrative embodiment of thehandle 12 is shown. Thehandle 12 is designed to receive, hold and/or transfer a material, such as toothpaste, to the brushing head 14 (shown in dotted lines). Accordingly, thehandle 12 contains at least one toothpaste storage area or chamber, illustrated herein as atoothpaste holding lumen 30. Thetoothpaste holding lumen 30 may be the same size as or smaller than the interior 11. Thetoothpaste holding lumen 30 begins at thefirst end 16 of thehandle 12 and runs the length of the body, terminating at a distal end 33 at or near the second opposingend 18. One or more handle bodytoothpaste dispensing channels 32 extend from the distal end 33 towards the brushing head 14 (brushing head shown in dotted lines). Thetoothpaste dispensing toothbrush 10 contains anopening 34 sized and shaped to allow for the placement of toothpaste into thetoothpaste holding lumen 30. Theopening 34 may be covered by cap 35 (seeFIG. 1A ). The cap may be designed to snap fit onto thehandle 12. In another embodiment, thecap 35 may contain male/female threading, which can be screwed into corresponding female/male threading positioned insidehandle 12. In yet another embodiment, thecap 35 may be hingedly connected. Alternatively, theopening 34 may be covered by a plug. -
FIG. 2B illustrates an alternative embodiment of thehandle 12 shown inFIG. 2A . Instead of thetoothpaste holding lumen 30 terminating at the distal end 33,toothpaste holding lumen 30 extends to the brushinghead 14. In this embodiment, the toothpaste stored within thetoothpaste holding lumen 30 can be directed toward and pushed directly into the brushinghead 14 without the use of the handle bodytoothpaste dispensing channels 32. - To aid in dispensing the toothpaste through the
toothpaste holding lumen 30 and into the brushinghead 14, theelongated handle body 20 may be made of a flexible material so that the user can squeeze the toothpaste the length of theelongated handle body 20.FIG. 2C illustrates anelongated handle body 20 which is made of a rigid or partiallyrigid portion 37, such as a rigid or partially rigid plastic, and aflexible portion 39. Theflexible portion 39 can be made of a flexible, bendable, or squeezable plastic to allow the user to manually push the toothpaste stored inside theelongated handle body 20 up to the brushinghead 14. The flexible, bendable, or squeezable plastic may be soft plastic laminate or a soft polyethylene, with or without aluminum. The rigid or partially rigid plastic material provides structural support and stability. Alternatively, thetoothpaste dispensing toothbrush 10 contains a mechanical assembly to accomplish the same. - Referring to
FIG. 3A , theelongated handle body 20 is shown with aroller device 36 adapted to roll along the outer surface of thetoothpaste holding lumen 30. As theroller member 36 moves toward the brushinghead 14, toothpaste stored within thetoothpaste holding lumen 30 is squeezed in a direction towards the distal end 33, and ultimately into the handle bodytoothpaste dispensing channels 32. - The
roller member 36 is movably attached toshafts cylindrical pin 65 andbracket 67, thereby providing a mechanism in which theroller member 36 moves forward/backward about thetoothpaste holding lumen 30. Preferably, theroller member 36 moves about theshafts motor 42 and gears 44 stored within theelongated handle body 20, see schematic,FIG. 4A . The motor and gears are driven bybattery 46. Pressingbutton 48 located on the outside of theelongated handle body 20 drives the entire process of moving theroller member 36. -
FIG. 3B illustrates an alternative mechanical actuating mechanism for moving toothpaste stored within thehandle 12 to thetoothbrush head 14. As illustrated inFIG. 3B and 3C , theelongated handle body 20 houses a material transport assembly, illustrated herein as amovable platform assembly 41. Themovable platform assembly 41 comprises anadjustment knob 43 coupled to a threadedrod 45 for selectively rotating the threadedrod 45. Aplatform 47 is coupled to the threadedrod 45 through abase portion 49 having a threadedaperture 51.
