APPLICATOR FOR WAX AND WAXLIKE SUBSTANCES Filed Sept. 20, 1951 2 SHEETS-SHEET 2 INVENTOR- MILTON J. COHEN 7 BY W MM ATTORNEY Patented Oct. 28, 1952 APPLICA'I OR FOR WAX AND- WAXLIKE SUBSTANCES v Milton J. Cohen, Washington, D. C. Application September 20, 1951, Serial No. 247 .523

4 Claims.

My invention relates to an applicator for wax and wax-like substances such as require to be softened by heat prior to use. Such substances are used in dentistry for relief of post-extractive pain and also to aid in combatting infection such as may appear in the socket from which a tooth has been extracted. Various measures have been proposed for application of pain relieving substances and antibiotics and the like, as by use of a powder or a paste or a gummy substance. It is difficult, however, to apply anything to a tooth socket because of reasons well known to dentists, such as the presence of blood and saliva and the difliculty of gaining access to the socket.

It is an object of my invention to provide means for softening a wax or a waxy substance and for applying the same effectively at the bottom of a tooth socket in such a manner that the substance will build upward from the bottom of the socket and will fill the cavity, while at the same time being hardened and cooled to body temperature by contact with saliva and by general internal oral warmth, this temperature being sufficient to hold the Wax in place long enough to perform its function.

Another object of the invention is to provide convenient and practical means whereby medicaments for preventing or combatting infection may be applied to a tooth socket simultaneously with wax or wax-like substance, and in a manner that is not harmful to the medicaments. Antibiotics such as penicillin, streptomycin, aureomycin, sulfa drugs, and other like therapeutic agents may be so employed, they being preferably combined or mixed with the wax.

Another object of the invention is to provide positive means for ejecting the softened materials froma container forming part of a package that is cheap and of simple construction.

Another object is to provide a package comprising an internal wax container, preferably a thin-walled cylinder of plastic material, having a downwardly bent nozzle, and an outer container of flexible plastic-material, said outer container being preferably cylindrical and concentric with the first container and the space between the containers being filled with material adapted to .evolve heat when wet, and one or more frangible capsules containing water or other fluid in said space, the fluid being such as to coact with the thermogenic material so as to give off heat and to soften the medicated wax.

Referring to the annexed drawings, which are made a part of this application and in which similar reference characters indicate similar parts:

. r Fig. 1 is a central longitudinal section of the preferred form of my invention,

Fig. 2, a cross section on line 2-2 of Fig. 1,

Fig. 3, a cross section on line 33 of Fig. 1,

Fig. 4, a view similar to Fig. 1, but showing the parts in a different position, 7

Fig. 5, a longitudinal section of a modified form,

Fig. 6, a section on line 6-6 of Fig. 5,

Fig. 7, a section on line 'l! of Fig. 5, and

Fig. 8, a view similar to Fig. 4, illustrating the operation of said modified form.

In the drawings, reference character l0 indicates an inner container of 'flexibleplastic material for holding medicated waxor like substance that .must be softened by heat for application in desired manner. This container is shown as cylindrical, and as having a laterally extending nozzle 'H to facilitate application of a dressing to the bottom of a tooth cavity or to the bottom of other wounds and the like. The container 10 is surrounded by another container I2 which is closed at its rear end by a head 13 against which the end of the container 10 bears. At its forward end the container l2 fits closely about container It or may be fixed thereto in any convenient or desirable manner.

The space between the concentric tubes is filled with a thermogenic compound M which may be such as that described in Patent No. 1,901,313 and in other U. S. patents, and any suflicient number of water-filled capsules I5 are distributed in the compound, the capsules being in such numher and siz as to provide the necessary amount of water to coact with the compound to generate the desired amount of heat for the purpose described and being suitably located to distribute the Water properly.

A plunger I6 is mounted for reciprocation in the inner tube II), in which it fits closely, said plunger being guided by a hole in head l3 and also by the tube I0. At its rear end the plunger has secured thereto a mantle l l of flexible plastic material, which serves to hold the plunger in line, to limit the outward movement of the plunger, and to protect the plunger from any dirt or other foreign materials. The head may have outstanding ears I8 projecting outward beyond the mantle.

All the working parts of the device are or'may be made of plastic material, it being evident that the parts I0, H, l3 and [8 may be rigid or semirigid, while part 12 should be sufliciently flexible to permit-the outer tube to be crushed so as to break the capsules l 5 and permit the liquid contents to escape. The plunger IE will ordinarily be rigid, and the mantle l 1 will be very flexible.

In use, the container l2 will be compressed sufficiently to break the capsules and release the water or other liquid, as indicated in Fig. 2. After so much delay as is needed to permit the chemicals M to coact with the liquid and soften the wax, the user will take the device in hand, as with the thumb pressing on the plunger to force it endwise through tube [0, and with two fingers engaging underv the projections l8, it to hold the body of theapplicator in place and in line with the plunger, and the nozzle being positioned to deposit the contents of the applicator at the desired point. The flexible mantle l8 may bulge, as shown in Fig. 4, or it may collapse into folds and creases. It is intended that the applicator will ordinarily be discarded after one use in View of its simple and inexpensive construction.

In the form shown in Figs. 5 to 8, the construction is generally similar to that of the form first described, the position of capsules I5 being slightly altered. Here I have shown an additional capsule It at the rear end of container l0 and have shown a head 13' fixed to the end of the outer tube H2. The operation of this form, as shown in Figs. 6 to 8, consists merely in compressing the flexible container I2 to break the frangible capsules, then after suitable delay to permit the thermogenic materials to react, the tubes [2' and Hi may be compressed longitudinally and endwise, with or without twisting, to eject the softened medicated .Wax or other contents, part It being flexible, as part (0 in Fig. 1.

It will be obvious to those skilled in the art that the device disclosed may be used for other but only as indicated in the appended. claims.

Having. thus fully disclosed my invention, what I claim is: I

I I. A device for dispensing heated fluent material comprising an inner container and a flexible outer container providing a space between them which is closed at its ends, frangible fluid-filled capsules in said space, material in said space for evolving heat on contact with said fluid, meltable material in said inner container, and a nozzle projecting from said inner container.

2. A device as in claim 1, said nozzle being bent laterally at its front ,end for injecting melted material into a tooth socket.

; 3. A dispensing device for medicated wax comprising inner and outer concentric tubes of flexible plastic material, providing a space between them that is closed at both ends, frangible waterfilled capsules in said space, material in said space for generating heat in the presence of water, medicated wax in said inner tube, and a nozzle on the inner tube, said nozzle being bent laterally at its free end for injecting melted wax into a tooth socket or'the like.

4. A device as in claim 1, wherein the closure at the rear end of said space is rigid, a plunger movable endwise of said inner tube, and a collapsible mantle connecting said closure to the plunger at a point remote from the closure.
