J. N. EIDT APPLICATOR Filed Aug. 20, 1941 Patented Aug. 29, 1944 UNITED STATES PATENT OFFICE APPLICATOR John N. Eidt, Elyria, Ohio Application August 20,- 1941, Serial No. 407,675

4 Claims.

This invention relates to improvements in applicators of that type adapted for ready attachment to the threaded nipple of a collapsible paste tube the latter functioning as a handle and a convenient means for supplying a. paste, such as v shaving cream, to discharge ports on the applicator, Heretofore, in applicators of this general type, the shaving cream is extruded through openings and spread over theface by bodily movement of the applicator. The quantity of cream supplied is greatly in excess of that required to effectively soften the beard due to the fact that the cream is discharged in direct proportion to the pressure exerted .upon the collapsi-ble tube and this results in waste as well as the counteracting resistance afforded by the face.

Another object of the present invention is to arrange the relatively movable parts in telescopic relation whereby the size of the applicator is maintained at a minimum without decreasing the efl'ioiency.

Another object of the present invention is to provide the applicator with a cream receiving chamber capable of being submerged in hot water to heat the cream if desired before application to the face.

Another object of the present invention is to so shape the spreader plate of the applicator that the cream will not pile up or slop over the plate when passing over the face.

Another object of the present invention is to provide an applicator of light weight, compact, simplified construction embodying sound engineering principles of operation, eflicient and inexpensive to manufacture and assemble.

With the objects above indicated, and other objects hereinafter explained in view, my inven tion consists in the construction and combination of elements hereinafter described and claimed. Referring'to the drawing: Figure 1 is a side elevational view of the applicator embodying the invention mounted upon a collapsible tube and. substantially full size.

Figure 2 is aside elevational' view of the applicator with portionsin section to more clearly illustratethe invention and shown on an enlarged scale. Figure 3 is an end elevational view of the applicator shown in Figure 2, looking at thedischarge end, and having portions broken away to more clearly illustrate details of the construction. Figure 4 is a fragmentary transverse sectional view ,taken substantially along line 44 in Figure 2 and showing details of spreader plate.

Figure 5 is a transverse sectional view of a modified form of applicator taken substantially along the dot and dash line 5-5 in Figure 2.

'Figure 6 is atransverse sectional view of'a further modified form of applicatortaken substantially along the dot and dash line 6'--6' in Figure2. Y v Figure"? is a fragmentary longitudinal vertical sectional view showing a modification 'of the sealing means, Y

- Figure 8 is a fragmentary longitudinal 'vertical sectional view of the spreader plate showing av further modification.

In the drawing I have illustrated one embodiment of the invention but it should be under stood that other adaptations'may' be made,' as will be obvious to those skilled in the art, and

the invention is, therefore, in no manner so reare attained when telescopically disposed. The

applicator has been made of metal and satisfactorily operated but it may be desirable to employ plastic material and the design and con-' struction illustrated affords such use without necessitating material changes.

The outer member II is of tubular form substantially square in cross section, as more clearly shown in Figure 3, and of suitable length. The inner end of the'tubular member II has an in wardly extending'marginal flange l3 while the outer end, in side elevation, terminates in an an: gular plane surrounded by an outwardly extending flared portion [4, as more clearly shown in Figure 2. A spreader plate l5 extends across the, open end of the tubular member II and has its marginal edge secured to the adjacent face of the flared portion I 4 after the member I2 is inserted in a manner to, befllater described. The outer face of the spreader plate I5 is bulged outwardly on a suitable curvature so as to pass freely over a person's face and prevent piling up of the dispensed cream. Any suitable opening may be provided in the spreader plate I5 to afford discharge of the cream therethrough but experiments have shown that a pair of relatively large openings I6 of substantially equal area and spaced relatively close together affords best results. A cover memher I! fits over the spreader plate l5 when not in use and is detachably connected to the adjacent free edges of the flared portion I4.

in the applicator. The cover member I! is next removed thus exposing the discharge openings I 6 in the spreader plate I5 and the latter is then run over the bearded face. A slight pressure is exerted between the spreader plate and face tending to force the tubular member II inwardly The inner member I2 is likewise, of tubular form substantiallysquare in cross section, as

more clearly shown in Figure 3, and slidably dis posed within the opening formed by the marginalflange I3 on the outer tubular member I I. Adjacent the outer end of the tubular member I2 is an outwardly extending peripheral flange I8 thev outer face of which is slidably engageable with the inner peripheral wall of the tubular member II thereby providing; with the flange I 3, suitably spaced. bearings to insure free. sliding movement of one within the other. To prevent any of the cream from working its way onto the outer exposed surface of the tubular member I2 a packing 'rin-g: I9 is suitably secured upon the free end of the latter in abutment with the adjacent face of the flange; I8: and sealingly but slidably engageable with the. inner peripheral surface of the tubular member I-I the: rin beingof' any suitable material; The inner end of the tubular'member I2 projects; a suitable distance beyond the inner end of the tubular member II and is closed by a cup-shaped; cap 20: the annular wall of which encircles and? is secured; to the: outer adjacent face of the tubular-member I2: wise, secured after the tubular member I2 has been disposed within the tubular member II to afford assembly. The end wall of the cap. 20 is provided with: an axially disposed interiorly screwthreaded opening 21 of" such size as'to permit its removable mounting. upon. a nipple of Modifications: of: the; cross; sectional shape: of

the tubular members: I I and; I 2 are shown inFigvures 5 and 6, the former being rectangular and the; latter round, the: numerals designating. corresponding: elements prefixed byone or two hundrediasthe. case may be thus necessitating no additional description. In: Figure; 8' a modification' of the; spreader: plate I5- is. shown wherein theouter. surface is covered by a layer of cloth such as feltor. the like. to assist in spreading the creamover thef'ace.

In. adapting-the: applicator for: use the; cap 20: is threadably mounted upon. the; discharge nipple, of a collapsible tube of shaving: cream and. is preferably so retained L1ntil;the cream has? been completely used. With the cover member I! in place upon the spreader plate I5 the tube is squeezed by the handin the-usual manner causing cream underpressure to-be discharged from the nipple-and flow into'the inside of th tubular members, l-2rand. I Is respectively until thespaceis completely filled. The flow. of cream is resisted by. the. presenceofrthe cover plate I! and by reason ofthecream being introduced .under pressure the tubular member II is moved outwardly until,

the flange. I3 engages .the flange I8. at which time. the desired quantity of cream has been supplied This cap 20:" is,. like-' which again exerts a pressur causing the cream in the applicator to pass through the openings I6 and onto the face in an even and smooth manner. When the outer tubular member II has moved inwardly until th flange I3 abuts the end of the annular wall on the cap 20 a predetermined quantity of cream has been applied to the face in an efficient and simple manner and the beard may then be removed by shaving in the usual manner. The operation is repeated for each new application and in the event that some may desire the cream to be warmed before being applied, th applicator can be submerged in warm water to raise the temperature of the cream. The applicator is so constructed that the usual messi ness accompanying the application by hand is entirely eliminated.

While I have described the preferred embodiment of the invention it is to be understood that I am not to be limited thereto inasmuch as changes and modifications may be resorted to without departing from the spirit of the invention as defined in the appended claims.
