ELI ZIMMERMAN BY A TTDRNEY5 TOOTHBRUSH MOUTHWASI-I RINSER KIT This invention relates to a combined toothbrush, mouthwash rinser and tumbler kit.
It is a principal object of the present invention to provide a toothbrush and rinser kit so that liquid for effecting rinsing of the mouth is provided in effect in the toothbrush, since the same can be used as a handle while brushing the teeth, thereby making unnecessary the use of spigot water as when traveling for the purpose of brushing ones teeth, thereby providing a toothbrush that can be used anywhere independently of the liquid source.
It is another object of the invention to provide a combined toothbrush and rinser kit that has an adapter or assembly with a squeeze bulb and on to which a tumbler can be releaseably secured and made available for supplying liquid and at the same time when attached to the adapter provides for a sanitary covering over the toothbrush to protect the brush against dust, bacteria, insects, and other harmful exposure.
Another object of the invention is to provide a combined toothbrush and rinser kit wherein the bottle in which the rinser liquid is supplied can be used as the bottle for dispensing the liquid through the adapter and through the toothbrush, the adapter being merely placed upon the neck of the squeeze bottle once the regular cap has been removed therefrom.
It is a further object to provide in a toothbrush and rinser kit an adapter which has a valve connection op erable by the threading down of toothbrush stem on to a valve projection carried by the adapter part so that the liquid can be closed off as with an ordinary cap so that there will be little loss from evaporation.
It is a further object of the invention to provide a toothbrush and rinser kit which will be compact for traveling as well as be good for home bathroom use and which will eliminate the scattering of brushes, drinking glass and rinsing solutions, toothpaste, toothache pain killer and yet adapted to easily fit into a hand for effecting the brushing operation.
Other objects of the invention are to provide a toothbrush and rinsing kit, having the above objects in mind, which is of simple construction,light in weight, easy to assemble, has a minimum number of parts, inexpensive to manufacture, of pleasing appearance, efficient and effective in use. 7

Referring now particularly to FIGS. 1 to 4, 20 represents generally the entire assembled bulb rinser, toothbrush, and glass tumbler joined together in kit form. The rinse bulb, as indicated at 21 can be formed of plastic material, which may be transparent, rubber, or the like and is provided with a neck opening 22 into which a bulbous portion 23 of a detachable nozzle 24 is fixed. It is conceiveable that the rinse bulb 21 may be constructed to be one piece. This nozzle 24 has a central hole 25 through which rinse liquid is forced by the squeezing of the bulb 21 to direct flow of the rinse liquid from its upper end 26 into the mouth upon completion of the brushing of the teeth or when the rinse liquid is desired only for gargling purposes. The bulb 21 is supported in a plastic vessel formed of separable bottom and upper parts 27 and 28. These parts are threaded together at 29 and upon them being released a bulb can be removed. The bottom part 27 is opposed to openings 31, 32 through which the fingers can be extended for effecting the squeezing of the inner bulb 21 to force the rinse liquid through the nozzle opening 25. The bottom of the part 27 is enlarged at 33 to provide a bottom support so that the kit will be supported on a shelf surface.
The upper part 28, like the bottom part 27 is flared at its bottom and provided with external threads to make the connection of this upper part 28 with the bottom part 27 at 29, although the bottom part 27 may be provided with internal threads to make the connection 29. The part 28 extends upwardly from its flaring to fully enclose bulb nozzle 24 and tapers upwardly to the upper end 26 of the nozzle. A brush sleeve element 34 has a hole extending axially therethrough, is tight fitted over the upper end of the upwardly tapered vessel part 28. This brush element has bristles 36 extending outwardly from the flat face 37 on the front of the element. Vessel part 28 is substantially rigid and can serve as a handle along with the bottom part for effecting the brushing of the teeth with the brush bristles 36. In order to keep the brush element 34 from turning on the upper end of the tapered part 28, a projection 38 extends inwardly into the opening 35 for engagement with a recess 39 in the upper end of the upper vessel part 28.
In order to close the opening extending through the nozzle 24 for the bulb 21, a cap 41, FIG. 6 is connected thereto by extending its depending pin shank 42 into the upper end of the hole 25 and the interior of the cap 41 fitted over a rounded upper end 26 although the end 26 and cap 41 could be a screw fit, of the nozzle 24. A stop ring 43 or retaining ring can provide for effective gripping of the cap 41 upon the nozzle end 26.
In order to complete the kit, a plastic or glass tumbler 44 extended over the toothbrush and nozzle top part 28 and can be releaseably threaded by internal threads provided on the tumbler with external threads on the outer periphery of the lower part 27 in order to releaseably secure the tumbler to the part 27 as best shown in 45 in FIG. 2.
In FIG. 5, there is shown a modified form of brush which is made in two parts, 46 and 47. The base part 46 is secured to the upper end of the bulb vessel container part 28 in the same manner that has been described in the brush element 34 in its connection with the part 28. This part 46 has a hole 47 for accommodating the upper end of the tapered nozzle end of the part 28 and this part would be shouldered therewith at 28 as would be the element 34.
In order to keep the part 46 from rotating there is provided a projection 48 in the hole 47 that will engage with a recess 39 in the upper end of the tapered part 28 as above described.
This end part 46 has a T-shaped slot 49 provided on its front face with inturned flanges 51 and 52 that has spaced locking recesses 53 for accommodating outwardly curved projections 54 when brush part 46 is slid into the slot 49 and the side projections 54 registered with the recesses or indentations 53, with the bot tom edge of brush part 46 being seated on stop 49 recessed in upper vessel part 28. The brush part 46 bears bristles 56 extending therefrom and these bristles can be of any hardness desired. By removing the brush part 46 from the slot 49 it can be replaced with a further part having less or more hard bristles 56 extra brush parts 46' can be stored within the tumbler 44 when the tumbler is fitted upon the flared lower end of the bulb container part 27 as at 45.
Referring now to FIGS. 7 to 10, there is shown a combined assembly of rinser bulb, toothbrush and tumbler which is formed of less parts than with the just described form of the invention. This kit is indicated generally at 60. The bulb 61 has its open neck end 62 tight fitted on to the lower end of a rigid toothbrush handle or stem 63 to which bristles 64 are directly attached at its upper end. This brush or stem has a depending reduced diameter portion 63' that extends to the lower end of the bulb 61. As the bulb 61 is squeezed liquid is forced upwardly through the hole 65 that runs full length of the brush stem or handle 63 and will be forced outwardly at 66 in the direction of the bristles 64. The bulb 61 has a flat bottom 67 on which the kit 60 can be rested.
The lower end of the stem 63 has an air intake opening 68 that will be closed as rinse liquid is forced upwardly through the hole 65 by a flap 69 when the bulb is released flap 69 will be opened to the dotted line position to allow air to pass into the bulb 61 to replace the liquid which has been dispensed.
The lower end of the stem 63 is provided with an annular flange 71 to have good gripping engagement with the interior of the neck 62 of the bulb 61. This neck 62 is further gripped by an external bulb housing 72 with depending inwardly curved gripping extensions 73 and 74 serving to contain the bulb 61 within the housing member 72. This housing member 72 has inwardly extending peripheral ridge 75 lying below the ridge 71 to grip the exterior of the neck 62 of the bulb 61.
A tumbler 76 held by its open end over the toothbrush stem 63 and the top of the housing 72 by an inwardly extending ridge 77 engaging tightly the exterior surface of the casing 72. In use the tumbler 76 is removed from the casing 72 to expose the brush bristles 64 and render the assembly ready for brushing of the teeth. The bulb 61 may contain tooth cleaning fluid or merely a rinse liquid as the bulb 61 is squeezed. Thereafter the tumbler 76 can be fixed to the casing 72 and the brush kept in a sanitary manner within the tumbler 76. The tumbler can be used free of the bulb 61 when one may desire a glass of water from the spigot for the further purpose of rinsing the mouth or for the taking of a pill. The bulb 61 can be refilled from water or liquid placed in the tumbler 76 by squeezing the bulb so that liquid will be extracted in the brush end 66 of the opening 65 that decends into the bulb 61.
Referring now to FIGS. 11 to 19, 80 represents generally a kit in which rinse liquid can be supplied by a squeeze bottle 81 from the Drug Store and which will be closed by a threaded cap 82 extended over an externally threaded neck portion 83 of the bottle 81. This bottle is made of resilient plastic material that has a memory and after being squeezed would return to its original shape. The cap 82 can be thrown away and replaced with an adapter valved cap 84 that is internally threaded and that can be screwed down tight on to the neck portion 83 of the bottle. This cap has an upwardly extending grooved diameter threaded portion 85 on to which can be threaded stem 86 having a hole 87 therein through which liquid can be forced and at its upper end having bristles 88 for toothbrushing purposes. At the lower end of the central opening 87 is a valve seat 89 which can be brought downwardly on to a round headed valve projection 91 to close off the opening in the manner as shown in FIGS. 12 and 16. Within the reduced diameter threaded portion 85 is a central hole into which the liquid is extended from the bottle neck portion 83 this liquid may pass upwardly through radi ally extending recesses 92 in a flanged head 93 upwardly from which the valve extension 91 extends. The flange 93 serves as a stop to limit the upward movement of the brush stem 86 as best seen in FIG. 17 wherein the flange engages with the shoulder 94 that extends annularly about the inner opening of the lower end of the brush stem 86.
Bottle 81 is provided with detent openings 96 near its top into which detent projections 97 on the inner face of a plastic tumbler 98 may extend to hold the tumbler in an inverted position over the toothbrush stem 86 and the adapter 84. It should be understood that toothpaste containers and other articles can be carried and concealed within the tumbler of the different forms of the invention.
When the toothbrush stem 86 is threaded downwardly the valve stem 91 will engage upon the seat 89 to seal off the flow of liquid from the squeeze bottle 81, and with a similar position shown in FIG. 16. When it is desired to make use of the toothbrush and of the rinse liquid, the toothbrush stem 86 is unthreaded to raise the valve seat 89 above the valve pin 91 to a position as shown best in FIG. 17.
It should now be apparent that there has been provided a multi-purpose kit comprising a squeeze bulb or bottle on which is mounted a plastic brush rinser shell and to the lip of this plastic shell a plastic glass detachably threaded or attached to enclose the toothbrush and to protect it against dust, bacteria, insects and other harmful exposure. This plastic glass provides storage space for small weekend size toothpaste tubes and extra brushes of different quality bristle strength. Where a brush element is removed from the rinser, the rinser can be used separately from the brush and still covered by the plastic glass. The plastic glass or tumbler can be used for medication or for drinking beverages when separated fromthe rinser shell. No other glass would be needed in the bathroom or for camping purposes.
While the brush is of various bristle strengths, from soft to hard, placing of the brush element on the rinser is a simple a procedure as sliding a cap upon a fountain pen. The brush element tightly fits or locks upon the rinser nozzle and are keyed against rotation thereabout. The rinser shell contains a soft plastic or rubber squeeze bottle or syringe that conforms generally to the shape of the shell. The shell has openings through which the fingers and thumb of the hand can be extended to effect a squeezing action upon the rubber syringe. According to the last form of the invention a valve is provided in a special cap that replaces an ordinary cap on the bottle in which the liquid is purchased and upon this special cap the toothbrush stem or handle portion can be threaded to open or close the valve surfaces extending between the toothbrush stem and the rounded upper end of the valve stem of the adapter.
It will be apparent that there has been provided a complete kit for mouth hygiene that can be used anywhere independently of a liquid source. The liquid in effect is carried in the brush handle and this liquid rather than being a rinser can be a toothbrush cleaning liquid. It can be readily seen that: once the toothbrush has been used that there is available for rinsing other than water a mouthwash solution. While various changes may be made in the detailed construction of the several forms of the kit, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
