s uru'llso- STATES PATENT OFFICE vf 4 Claims.

This invention relates to new and useful 'imv provements in applicators which may be used for dispensing shaving cream, tooth paste or the like.

It is the object of the present invention to provide an applicator which is inexpensive to make and which may be readily attached to a tube of shaving cream or a container of other substance to be dispensed, discharge a snall quantity upon pressure applied thereto, and guard the' contentsof the tube from wastage or contamination when not in use. The applicator consists of a soft rubber o r other pliable housing having a central cavity into which shaving cream or the like may be forced from the container. The cavity is connected with the outside through a discharge slot formed in the housing wall. Means in the fonn of an outside closing strap, or a spring embedded in the housing wall, or both, maintain the applicator under tensionso as normally to close the slot. The tension may be relieved by loosening the strap and by applying pressure on the outside of the housing, whereupon the slot is opened and the contents of the-cavity discharged through the slot.

This and other objects of the invention will more fully appear from the following detailed description of two` exemplifications of the in' ventlon and the appended claims.

, In the drawing, Figs. 1 and 2 are a longitudinal cross section and a top plan view,A respectively, of one embodiment, and Fig. 3 is a longitudinal cross section of a invention.

The shaving cream container- 1 is provided' with the usual screw-threaded nipple 2 on which the applicator housing 3 of soft rubber or other roughened knob 8 on top of the applicator 3.

The point where the two parts of the closing strap 6 meet is depressed into a lower plane, as clearly shown in Fig. 1, and presses against the shoulder 8 formed in the applicator, the length of the part 6 of the strap being such as to rotate the head of the applicator so as to close theslot 13 in the lower part thereof.

When it is desired to dispense the contents of second embodiment of thecontainer 1 the latter isrolled up at its end in the usual manner, its contents discharging within the cavity in the center of the applicator 3. The applicator `is nowplaced against the face or other surface or object to be coated with the roughenedportion 12 touching the .face, thev closing strap having been swung back on its hinge by grasping the circular end portion 7' thereof. The user presses down on a roughened portion lnear the center of the upper surface of the applicator. Tension on the front part of the applicator having been removed by throwing .back the closing strap, pressure applied atpoint 10 will tend to straighten out aspring 14 embedded in the body of the applicator and fastened into thebushing 4. Normally, this spring tends to rotate the front portion of the applicator downward thus closing theslot 13, but when vas above stated, pressure is applied at 10, the slot is opened and owing to continued vpressure at 10, -the contents are forced out from the cavity inthe applicator through-the'slot 13. Bending of the applicator is limited by ametal reenforclng member 15 below the cavity, one end of said member being fastened to the `bushing 4.

The shaving cream or the like Vmay be spread by the roughenedportion 12 and also by thenose 11 of the applicator. When the applicator is used for dispensing materials such as depila-v tories, creams or lotions, thenose 11 is prefer- -ably of metal or has a blade of metal embedded therein so as to permit its use not only to spread vthe cream,` but also to, remove from the skin hair or thelike.

In certain cases it may be found that the applicator when pressure is applied atpoint 10, will tend to discharge its 'contents not only through the slot but also back into thecontainer 1. In such vcases the construction shown in Fig. 3 is preferred wherein the central cavity of the applicator 3 connects with the inlet opening through a restricted` passageway which is closed when pressure is applied at 10. It will be noted also that in this construction the end 21 of the spring is bent up instead of downward as shown in Fig. 1 and projects through the nose 1l of the'applicator for the purpose of removing' hair and the like in the manner previously de. scribed.

Theslot 13 should preferably be pierced so as to form a .clean-cut opening. If thespring 14 is made stiff enough to keep the-slot 13 normally closed, the closing strap 6-7 may be dispensed with.

'I'he metal bushing 4 with the reeni'orcing cavity, means for attaching the applicatonto.N a container of the substance to be dispensed,`

and a spring embedded in the housing tensioning the latter to close saidslot 2. In an applicator, a. pliable rubber .hcknnisingl having a central cavity anda `slot opening into said cavity, means for attaching the@ housing to a. container oi the substance tobe dispensed,

vaY spring' a 'relatively rigidbar embedded in the housing on' two` opposite '-sides of the cavity, Iand a tensioningfstrapl attached to the'outside of the housing fi Y f 3; In an applicator, ajrubber housing open at one end; having ascentral cavityland a slot connecting said cavity with the outside through the wall of the casing, a hollow bushing in the housing at its open end for attaching the applicator to a' container, a restricted passageway in the housing connecting thecavity with the container through said bushing, a metal spring embedded in said housing above the cavity and having one end mounted in said bushing and the other end projecting through said housing, a reinforcing bar embedded in the housing below the cavity and mounted. on saidbushing,

`and a closing strap hingedly "connected to said bushing and engaging the outside of the housing at a point substantially opposite to the opening of said slot.

4. In an applicator, a pliable resilient housing having a central cavity and a slot near the tip of said applicator opening into said cavity, means for attaching said applicator at its base to a container of the substance to be dispensed, a plate rigid as compared with the housing and contacting therewith over a relatively small area near its base, said base terminating at a point between said slot and the base of the applicator whereby the resiliency of said housing will maintain said slot closed unless it is forced open by placing said housing under pressure.
