l Massapequa, N.Y. Filed Sept. 11, 1962, Ser. No. 222,892 Claims. (Cl'. 132-84) This invention relates to brushes, and more particularly to brushes having a self-contained supply of material `capable of being dispensed toI the brush;

One object of the invention is to provide a toothbrush having self-containedv means4 for dispensing a dentitrice. t

Another object of the invention is` to provide a` container means of the dispensing type for storing a quantity of a paste-like dentifrice in a manner convenient for use While traveling, as well as in the home.

Still another object of the invention is to provide storage container means for a toothbrushl and supply of toothpaste. l

A still further object of the invention is to provide a combined traveling case for toothpaste and a toothbrush with means to dispense the paste to the bri'stleswhen needed.

Another object of the invention is to provide a prefilled tube, or capsule, of toothpaste capable of attachment to a dispensing-type of toothbrush and which mayI be discarded when empty.

Other objects and advantages will be apparent to those skilled in the art after reading the following specification `in connection with the annexed drawings, in which:

FIG. l is a perspective View of a preferred form of combined dentifrice-dispensing container and toothbrush in accordance with this invention;

FIG. 2 is a longitudinal cross-section taken o'n line 2-2 Aof FIG. l;

FIG. 3 is a cross-section in the same plane as that of FIG. 2, but with the protective cover removed and with the brush portion in position for dispensing the dentifrice;

FIG. 4 is a longitudinal cross-section taken in the plane disposed at right angles to the plane of FIGS. 2 and 3, and With the brush portion in operative position;

FIG. 5 is a transverse cross-section, on an enlarged scale, taken on the line 5-5 of FIG. 4;

FIG. 6 is a transverse cross-section taken on the line 6 6 of FIG. 4; and Y FIG. 7 is a transverse cross-section taken on the line 7-7 of FIG. 3.

Referring ynow to the drawings in detail, the invention is shown as broadly including a dispensing portion, indicated generally by the numeral 10, `and a brushing portion, indicated generally by the numeral 11. Practically all of the components of the device are preferably molded of a suitable plastic material, although metal or other materials could be used.

The dispensing portion 11 preferably comprises a cylindrical barrel 12, enclosed at one en d by the end Wall 13. Slidingly tted within the barrel is a generally discshaped plunger 14 having a centrally located longitudinally extending bore 15. Extending across the rear opening of the bore in a valve means, for a purpose which will later be apparent, which may be comprised of a membrane 16 formed of flexible material and provided with a pair of diagonally slit openings 17, as shown in FIG. 5, defining a series of circumferentially arranged flaps 18. If the plunger is formed of some pliable material, such as polyethylene or the like, the membrane 16 can be integrally formed with the plungerto provide suiiicient flexibility for the flaps 18 to be capable of yielding movement.


3,227,165 Patented Jan. 4,- 1966 ice brush, preferably in' paste form, is contained Within the` barrel between the endl wall= 13" and the sliding plunger' 14, as indicated by the numeral 19.

The' brush portion 10 comprises an elongated tubular shank 20, preferably formed of some plastic material, having a set of bristlesZl` embedded along the side at one end. Appropriately disposed within the midst of the bristles is' a radially outwardly extending feeder tube 22, composed of some soft` pliable material such as plastic orf rubber, preferably plastic,y which is in communication with the hollowr interior 23 of the shank. The other end of the shank is receivedwithin the barrel 12 andV is pro-A videdwith a radially projecting annular boss' 24V slidably received therein. In order to permit free -sliding movement of the shank, the boss is provided with one or more longitudinally extending air passages 25, as may best beV seenin FIG. 6.

The other end of the shank is also provided with an axially projecting cylindrical coupling portion 26- which may be-sl'id'ably received inl close tting engagement withinl the bore 15` of the plunger. The outer end of the cou'- plingz is closed by a flexible membrane 27 provided with one or more diagonally extending slits 28 to provide a valve means for retaining paste contained within the hollow interior of the shank. As in the case of the membrane I6, the membrane 27 may be formedintegrally with the shank portion or it may be formed separately and secured to the shank by suitable adhesive or other means.

The shank- 20 isv contained within the barrel 12 by means of a removable cap 29', provided with an inwardly projecting annular flange 30, against which the' outer shoulder 31 of the boss 24 will abut when the shank is fully projected. In addition', the ila'nge may be provided with one or more recessed dimples 32 (see FIG. 7) within which the projections 33, provided on the exterior of the shank, Will be received to prevent relative rotation of the shank with respect to the barrel when the brush is in use.V t

The cap 29 is preferably formed of slightly flexible plastic in order to permit the projections 33 to pass from one side to the other of the flange 30 when it is desired to retract the shank. The cap may be secured to the barrel by threaded engagement, but as shown in the drawings, an annular recess may be provided for snap-on engagement with the annular bead 34. To protect the brush portion for packing and traveling, and to prevent the toothpaste from becoming hard or caked due to exposure, a clear plastic cover 35 may bepr'ovided, the open end of which may be provided with an inwardly extending flange for snap-on engagement with an annular bead 36 provided on the cap 29.

In use, the interior of the barrel 12 is iirst lilled with an appropriate material such as a dentifrice, preferably in paste form, by removing the cap 29 and the plunger 14. Or, since the barrel may be made of inexpensive plastic material, it may be prepacked with toothpaste by the manufacturer With the plunger 14 already in position, so that When the paste has been used, the barrel and plunger may be discarded entirely. The plunger is then replaced with the membrane 16 in contact with the paste. The shank 20 is replaced by inserting the coupling portion 26 within the bore of the plunger, so that the boss 24 may be received Within the outer end of the barrel. The cap 29 is then attached so that the relative positions of the elements will be as shown in FIG. 2.

When it is desired to dispense some of the paste material on the bristles, the shank 20 may be moved towards the right with respect to the valve, as shown in FIG. 3; the force required being sufficient to push the projections 33 past the flange 30 by temporarily distorting the cap. This movement of the shank will cause the boss 24 yto come into abutting engagement with the plunger 14, thus causing it to move towards the right and forcing paste contained within the space 19 to dei-lect the flaps 18 ofthe membrane 16 and the similar flaps of the membrane 27 to permit the material to pass to the left into the interior passage 23 of the shank to the feeder tube 22, and finally upward to be distributed adjacent the upper ends of the bristles 21.

When a sufficient amount of paste has been dispensed in this manner, the shank 20 is disengaged from the plunger and returned to its projected position as shown in FIG. 4; the projections 33 being seated within the dimples 32. It will be noted that the plunger 14 will remain in position adjacent the supply of paste and that the presence of the valve means formed by the respective membranes 16 and 27 will effectively prevent leakage of the paste from the chamber 19 and the hollow passage 23. However, Whenever an additional amount of material is desired on the bristles, it is only necessary to move the shank again towards the right so that with the coupling 26 received within the bore of the plunger, further movement of the plunger towards the right will cause additional amounts of paste to be forced into the interior of the shank and up to the area of the bristles.

While the present invention has been described and shown as having particular utility in the form of a toothbrush, it should be understood that it may be modified for use in other applications where it is desired to dispense a viscous or paste-like material to a surface to which a brushing action is to be applied.

Having disclosed a preferred form in which the invention is to be practiced, it should be understood that such other modifications and improvements may be made by those skilled in the art which would come within the scope of the annexed claims.
