TOOTHBRUSH ADAPTER FOR AEROSOL CONTAINER
United States Patent 3825354
A toothbrush has a hollow head into which head the user can inject toothpaste from an aerosol can. The aerosol can includes a valve in its upper portion which is spring loaded closed and adapted to be opened in response to pressure on a cylindrical plug extending upwardly through the top of the can. An adapter mounted on the aerosol can is adapted to receive the toothbrush so that it can be guided into a position which permits the user to push on the handle of the toothbrush to actuate the valve, and an injector tube also provided in the top of the aerosol can is received in an end opening associated with the hollow head of the toothbrush so that the user can grasp the aerosol can in one hand on the toothbrush in the other and thereby load his toothbrush in an efficient manner.

I claim
1. The combination comprising an aerosol type container having an upper end which defines a annular rib, a valve assembly in the container and operable in response to downward pressure on a generally cylindrical valve actuating member disposed centrally of said annular rib, a small diameter tube extending upwardly through said valve actuating member, and an adapter having a base fixed to said annular rib, said adapter having a central opening for slidably receiving said cylindrical valve actuating member, a toothbrush having a head portion with bristles or the like, and said toothbrush having a handle portion of conventional configuration, said toothbrush head portion having an internal chamber and having an end opening for receiving said tube, said adapter further including an upstanding portion with a recess for receiving the head portion of said toothbrush generally axially with respect to the adapter so that axial pressure on said cylindrical actuating member can be exerted by the user as a result of pushing on the handle portion of the toothbrush.

Description:
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to toothbrushes of the type having an internal chamber for storing a limited quantity of toothpaste, and deals more particularly with the combination of such a toothbrush, and adapter means for loading the toothbrush with toothpaste from an aerosol can.
In U.S. Pat. No. 3,022,789 a proposed solution to this problem is shown, which requires that the user depress a button to open the valve associated with the aerosol container, and simultaneously hold the toothbrush in position with respect to an injector in order to load the toothbrush.
The present invention permits the user to open the aerosol valve as he inserts his toothbrush in a unique adapter carried by the otherwise conventional aerosol container.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an overall view of the aerosol can together with the adapter and a portion of the toothbrush which is adapted to be received in the adapter.
FIG. 2 is an alternative construction wherein the toothbrush is adapted to be received at 90° to the orientation of the central axis of the aerosol can.
FIG. 3 is a detailed view of the upper portion of the aerosol can, portions thereof being broken away to better reveal the construction of the adapter, said adapter being shown at least partly in section. The head portion of the toothbrush of FIG. 1 is also shown in this view.
FIG. 4 is a sectional view taken on the line 4--4 of FIG. 3.
FIG. 5 is a sectional view of the head portion of the toothbrush together with the valve actuating portion of the aerosol can, the adapter being removed for clarity.
FIG. 6 is a detailed view of the head portion of the adapter, and
FIG. 7 is a sectional view taken on the line 7--7 of FIG. 5.
DETAILED DESCRIPTION
Turning now to the drawings in greater detail, a conventional aerosol can is indicated generally at 10 in FIG. 1, said can having a top or upper portion 12 which includes a central opening 14 defined by an annular central insert member 16, which member 16 is spun into mating relationship with the top 12 of the aerosol can in a conventional manner and so as to define an annular rib 18. A conventional valve 13 is provided inside the aerosol can 10 being spring loaded closed variety and adapted to being opened in response to downward pressure on a generally cylindrically shaped actuating member, or plug 20. As shown in FIG. 3 when this plug 20 is depressed the valve 13 is opened allowing the contents of the aerosol container to pass upwardly through the bore 22 defined for this purpose in the member 20. An injector tube 24 is preferably mounted in the bore 22 of the actuating member or plug 20. Thus, both the tube 24 and the plug 20 are depressed for opening the valve 13. The plug 20 is spring returned for closing the valve.
An adapter 30, preferably fabricated from a thermoplastic material by an inexpensive process such as by plastic injection molding is provided in mating relationship with the upper end of the aerosol can 10. More particularly, the adapter 30 is snugly received on the annular rib 18 by means of an annular flange 32 provided for this purpose on the base portion of the adapter 30. The adapter 30 further includes a central opening 34 for slidably receiving the actuating member 20, associated with the valve 13, in the aerosol can. As best shown in FIG. 4, the adapter 30 also includes an upwardly extending cavity for receiving the head portion of a toothbrush.
The toothbrush itself is of conventional construction being similar to that shown in the above mentioned U.S. Pat. No. 3,022,789 issued to Theodore Rallis et al. Feb. 27, 1972. More particularly, the toothbrush shown in FIGS. 5, 6 and 7 preferably corresponds to that disclosed in this prior art patent, and also includes a conventional handle portion. The head portion defines an internal chamber having a slot 42 on one side, that is in the side which carries the bristles, in order to permit the toothpaste to flow into the middle of the grouping of tufts or bristles. The end of the toothbrush associated with the head is also provided with a smaller cylindrical end opening 44 for receiving toothpaste from the tubular injector 24 and this end opening 44 communicates with the internal chamber 40 for this purpose. As so constructed and arranged toothpaste may be injected into the chamber and hence pass outwardly through the slot onto the bristles very expeditiously.
The principle advantage of the present invention relates to the novel means for injecting toothpaste into this chamber 40. The chamber 40 as best shown in FIG. 5 communicates with the slot 42 and with the end opening 44 to define a passageway for the toothpaste. The bristles may be integrally molded with the toothbrush handle portion, or may be more conventionally mounted in the head portion when the plastic toothbrush is formed. FIG. 5 also shows one end of the plug member 20 which comprises a part of the aerosol valve in the container 10, as well as the tubular injector 24 associated with this plug 20.
Returning once again to a more complete description of the adapter 30, its upper end is opened or slotted as best shown at 38 in FIG. 4 to receive the head portion of the toothbrush described above. This adapter 30 is provided with a cut away portion or opening 36 which permits the adapter to be conveniently raised out periodically by the user. Although it will be apparent that this adapter might be solid in this area it is preferably cut away as shown to provide a convenient way of cleaning the adapter periodically to remove any residue of toothpaste or the like.
Still with reference to the adapter 30, and more particularly with reference to the toothbrush handle receiving slot 38, FIG. 4 also shows lips 39, 39 which serve to retain the toothbrush in the slot 38 while the user exerts downward pressure on the handle portion, thereby assuring that the necessary downward force is exerted on member 20 as he inserts the toothbrush in the adapter. The injector tube 24 will also be so guided as to penetrate the small end opening 44 as best shown in FIG. 5 when the toothbrush is pushed downwardly in the slot or recess 38, as best shown in FIG. 3.
This invention relates to toothbrushes of the type having an internal chamber for storing a limited quantity of toothpaste, and deals more particularly with the combination of such a toothbrush, and adapter means for loading the toothbrush with toothpaste from an aerosol can.
In U.S. Pat. No. 3,022,789 a proposed solution to this problem is shown, which requires that the user depress a button to open the valve associated with the aerosol container, and simultaneously hold the toothbrush in position with respect to an injector in order to load the toothbrush.
