Abstract
A toothbrush having a water reservoir in the handle and squeezable to force water therefrom through a plurality of spaced apart orifices located at the base of bristles that project from the head of the brush.
Description
- This invention relates generally to dental hygiene and more particularly to a toothbrush having a reservoir for water, or other liquid cleanser, in which the reservoir communicates via fluid flow passages with the brush end of the toothbrush and operable for dispensing the cleansing fluid therefrom.
- A supply of water, or other cleansing fluid, is essential for properly cleaning ones teeth. It is common practice to turn on the water faucet and let the water run while brushing to rinse off the brush and also to convey water, via the brush, to the mouth for cleaning. Children, and others that spend a lot of time brushing their teeth, can leave the faucet running for a long time for each brushing. This wastes water and is of considerable concern particularly in places where there are water shortages or a lack of a sufficient supply of potable water. There is not always a safe and clean supply of water available for example when traveling in countries where the tap water in unsafe for human use. Also when camping or hiking, water conservation and/or the absence of water and/or whether or not the water is safe to use can be of concern and thus it would be comforting to know that one has their own water supply, or other suitable cleansing fluid, available and safe to use.
- In addition to the forgoing often difficulties are encountered by an elderly or disabled person, particularly when bedridden, when trying to clean their own teeth or when such task is undertaken by a care giver. Today it is common for the elderly, because of good dental hygiene practice throughout their lives, to have their own natural set of teeth and therefor cleaning in situ is required.
- Furthermore, service man assigned to armed service units in the jungle or desert areas often find potable water scarce.
- A principal object of the present invention is to provide a toothbrush having means for dispensing a cleansing fluid from the head end of the brush.
- A further principal object of the present invention is to provide a toothbrush with its own supply of a cleansing fluid that can be dispensed when needed and with ease from the head of the brush.
- A further principal object of the present invention is to provide a toothbrush incorporating therein a reservoir for a cleansing fluid and means whereby the cleansing fluid can be readily dispensed from the head of the toothbrush by applying hand pressure to the toothbrush handle.
- A further object of the present invention is to provide a toothbrush with a water reservoir so that there is no need to turn on the water faucet until the reservoir needs refilling.
- A further object of the present invention is to provide a toothbrush with a carry along supply of cleansing fluid that one knows is safe to use while traveling, hiking or camping.
- It is another object of the present invention to provide a valve in the handle to regulate the flow of water to the bristles of the brush.
- It is another object of the present invention to provide an adapter for attaching the handle of the brush to a supply of water such as a bottle or cartridge.
- These and other objects are accomplished by a toothbrush provided in accordance with the present invention in which the toothbrush handle has a fluid confining chamber therein defined at least in part by a flexible wall for varying the volume of the chamber by applying hand pressure to the handle and a fluid flow passageway from the chamber to outlet orifices in the head of the brush adjacent the base end of the bristles that project from the head.
- A preferred embodiment provides a toothbrush including a handle having a fluid confining chamber providing a reservoir defined at least in part by a flexible wall for use in varying the volume of the reservoir by applying hand pressure to the handle. A head connected to the handle and having a plurality of bristles projecting therefrom is provided with a plurality of spaced apart orifices in the head disposed at a position adjacent a base end of the bristles. Passageway means connects the reservoir in fluid flow relation with the orifices. Optionally a screw or friction fit connection may be used as an adapter to connect the distal end of the handle to a portable water source such as a bottle of water or cartridge containing same. It is anticipated that a plastic bag containing water could be inserted into the cartridge. A means for piercing the bag or cartridge of water such as a removable hollow lance may be incorporated with the removable water source adapter.
- Other objects, features, and advantages of the invention will be apparent with the following detailed description taken in conjunction with the accompanying drawings showing a preferred embodiment of the invention.

toothbrush 10 having ahandle 20 and abrush head 30 interconnected by astem 40 interposed there between. The stem is preferably curved as seen in FIG. 1 but if desired it maybe straight. The handle in general is of an ergonomic design to fit comfortably in the palm of ones hand and has areservoir 21 therein for holding a supply of water or other tooth cleansing fluid. - The
brush head 30 has acluster 31 of bristles surrounding each of a plurality of spaced apartorifices 32 arranged by way of example geometrically in 5 rows in the longitudinal direction of the handle and in 13 rows transverse thereto. The number of rows are purely by way of example and maybe varied to suit ones desires for performance of the toothbrush. The array of orifices maybe geometrically arranged or they maybe randomly arranged on the surface of the brush head. The outer terminal end of each cluster of bristles is preferably contoured for example suitably rounded as indicated at 33 to provide good tooth contact and adjacently disposed clusters preferably differ in height from one another again for the purpose of providing good tooth contact. The head has acavity 34 therein that serves as a manifold and each orifice is in fluid flow communication with such manifold. - The
water reservoir 21 is in fluid flow communication with the orifices via apassageway 41 through theneck 40 and themanifold 34 in the brush head. A one wayflow control valve 42 is located between the reservoir and the orifices and maybe located in thepassage way 41 or at the juncture of the reservoir and the passage way as illustrated in FIG. 3. The valve maybe retained in position by being in a press friction fit relation in an enlargement at the commencement of the passage way and inserted there into through anopening 22 into the reservoir.

The flexible portion allows the user to vary the volume of the reservoir decreasing such volume by squeezing on the handle and thereby forcing liquid from the reservoir through the passageway into the manifold and out through the orifices. The oneway valve 42 prevents contaminants from returning to the reservoir from the brush head and thereby ensures one having a clean supply of cleansing fluid at all times. Theflexible portion 26 maybe a plastics material or rubber and preferably is self sustaining in shape whether the reservoir is filled or not but soft enough that a gently squeeze will expel water from the reservoir through the orifices in the head when the reservoir is filled. - The handle
rigid portion 25 is cup shaped with the bottom of such cup providing a support base for the reservoir. The reservoir maybe provided by a covering overlying the rigid portion of the handle or alternatively it maybe a bladder type unit separately provided and fitted into the cup portion and secured in any convenient manner e.g. by hook and loop cooperating fasteners. In either instance it is preferably of a material that exhibits a soft to touch feel. In the case of a bladder it would obviously provided with a spigot attachable by a leak proof connection in fluid flow relationship with thepassage 41. - In the embodiment illustrated in FIG. 4, the
cap 23 previously described is replaced by a cap designated 23A which has ameans 50 for connecting thereto one end of aflexible conduit 51 the other end of which connects via acoupling 52 to abottle 60 containing water or other suitable cleansing fluid for ones teeth as best shown in FIG. 5 as a threaded coupling. In this embodiment, the reservoir may be smaller in volume than in the embodiment of FIGS. 1 to 3 and if desired it could even be eliminated if the bottle was made of a flexible or the like material so that it could be squeezed and thus become the sole source of supply of cleansing fluid. Moreover, the bottle could be used to refill the toothbrush handle, removed before use, and resealed or recapped and any remaining liquid saved for use at a later time. - As shown in FIG. 6, the toothbrush includes a
water cartridge housing 70 having a threadednozzle 72 for threadably engaging the internal threads in the adapter in the distal end of the toothbrush handle. The assembly includes a means for sealing and piercing such as a washer ordisc 74 having ahollow lance 76 extending therefrom for piecing anend wall 78 of the cartridge housing which may be comprised of a thin plastic film or a membrane (such as composed of aluminum foil, plastic film, etc.) which releases the water/liquid from thecartridge housing 70 upon threadably receiving same puncturing theend wall 78 with thelance 76. As shown thewater cartridge housing 70 is cylindrical; however, it is contemplated that the housing could be of any ergonomical shape or fanciful design. - As illustrated in FIG. 7, the toothbrush includes a
cartridge housing 70 having a threadednozzle 72 for threadably engaging the internal threads in the adapter in the distal end of the toothbrush handle. The assembly includes a plastic disposable cartridge 80 having a pierceable end wall and means for sealing the periphery of the cartridge against the adapter of the handle and means for piercing the cartridge 80. The means for sealing and piercing anend wall 81 of the cartridge 80 may be a washer ordisc 74 having ahollow lance 76 extending therefrom for piecing the end wall of the cartridge 80. Theend wall 81 of the cartridge 80 may also be formed or composed of aluminum foil, plastic film, etc.) so that piercing same releases the water from the cartridge 80 upon threadably engaging thecartridge housing 70 to the handle adapter. - FIG. 8 shows the toothbrush which includes a
cartridge housing 70 having a threadednozzle 72 for threadably engaging the internal threads in the adapter in the distal end of the toothbrush handle. The assembly includes a plasticdisposable water bag 82 for insertion into thecartridge housing 70. Thewater bag 82 has a pierceable end wall and means for sealing the periphery of thewater bag 82 against the adapter of the handle and means for piercing thewater bag 82. The means for sealing and piercing thewater bag 82 may be a washer ordisc 74 having ahollow lance 76 extending therefrom for piecing the end wall of thewater bag 82. An end wall 84 or fill port of thewater bag 82 may also be formed of or composed of a ring or washer formed of aluminum foil, plastic film, etc.), which upon piercing releases the water from thewater bag 82 upon the handle adapter threadably receiving thecartridge housing 70. - The
cartridge housing 70 and/or any of the reservoir supply devices attachable to the handle of the toothbrush can be used connected to the toothbrush; however, it is anticipated that the reservoir supply devices such as the cartridge or bag within the cartridge housing or the cartridge housing itself would normally be disconnected from the toothbrush handle prior to using the toothbrush. - Alternatively, the tooth brush reservoir could be used to draw water from the bottle in which case the bottle connection could be vented and the tube51 (or extension thereof) project into the water in the bottle as illustrated in FIG. 4. In such an embodiment it maybe necessary to have a back flow preventing valve in the
