1952 c. H. BRASELTON NONRETRAC'IABLE LIPSTICK Filed Sept. 15, 1948 Qnoentor Patented Oct. 7, 1952 UNITED STATES PATENT OFFICE NONRETRACTABLE LIPSTICK Chester H. Braselton, New York, N. Y.

Application September 15, 1948, Serial No. 49,328

1 Claim. 1

This invention relates to lipstick, pomade, solid perfume, and other applicators therefor, and is an improvement on the construction shown in my co-pending and allowed application, Serial No. 699,025, filed September 24, 1946, now Patent No. 2,457,342, and has to do with the designs and constructions for reducing the cost of manufacture of such articles by simplification of construction and design, and reducing and simplifying the mechanical parts used in the manufacture of same, thereby improving the durability, service and life of such devices.

In the device shown in said application the lipstick material is adapted to be fed to the applying end of the lipstick container by means of feeding mechanism inside the container which includes a plunger kept from rotation with respect to the container by means of a spline or some cross-sectional relationship other than circular, between the plunger and container. In that design the screw which feeds the plunger is immovably connected to and supported by an end piece, closing one end of the container, and rotatively connected thereto in a counterbored portion of that end of the container. In my present device I have improved upon the relationship between the feeding plunger and the inside of the container wall, and eliminated the counterboring of the closed end of the container while still having the end piece which carries the feeding screw permanently close that end of the container. I further have this closure, in addition to projecting inside the closed end of the container, provide an enlargement outside the end of the container of a diameter greater than the diameter of the container proper to provide a shoulder to receive and support a removable cap or cover for the lipstick or other pomade casing, the projecting closure serving as a base for the container.

The construction is simplified and its cost reduced by having the closure for the container in one piece with the base. This closure has a. groove on its smaller diameter into which the to-be-closed end of the container is adapted to be spun for permanent rotative connection, but non-longitudinally movable relationship between these two parts.

For a more detailed description of my invention, reference is hereby made to the drawings which accompany and form a part of this application, and in which:

Fig. 1 is a perspective view of my lipstick with the cap therefor assembled thereon.

Fig. 2 is an enlarged longitudinal section taken on the line 2-2 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a perspective view of my lipstick with the cap or cover removed, filled with lipstick rouge, and

Fig. 4 is a cross-sectional view of Fig. 2, taken on line 4-4, looking in the direction of the arrows.

In the drawings, I is the shouldered base of the container, and 2 the removable cover in place thereon in Fig. 1, but removed in the showing of Fig. 3. The cover'2 is of conventional form, being open at one end and closed at the other, and being adapted to be squeezed a little out of shape at the open end so as to make satisfactory frictional contact with and be supported on shouldered portion 3 of the base, slightly less in diameter than the largest diameter of the base. The cap 2, when in place on the base I, is adapted to frictionally engage the periphery of the shoulder 3, and be frictionally held in place with its open end abutting the surface joining the largest diameter of the base I and its next smallest diameter 3. The base I has, also, a shoulder 4 and a peripheral groove 5 between it and the portion of diameter 6, larger than the smaller diameter of the groove 5, the periphery of the diameter Ii itself adapted to snugly but rotatively fit the inside diameter of the container 1 so that when one end of the container I is placed over the shoulder 6 on the base I and pushed thereover until it abuts the shoulder 4, the container 1 may be then spun inwardly at 8, to make a permanent rotative but non-longitudinally movable connection between the base I and casing I. The inside diameter of the casing 'I is circular and is preferably made of standard tubing.

The base I has a hole 9 adapted to receive a screw III, of small diameter, and threads of a large number to the inch. This screw, when assembled in the base I, is either by a forced fit, soldering. peaning, or otherwise, held permanently in immovable relationship with respect thereto, the base holding the screw axially in the casing when properly assembled in the casing I. The plunger II has a central hole screw-threaded to lit the threads of screw I0 and has a periphery I2 generally fitting the inside diameter of the casing I. This plunger is provided with a peripheral groove I3, adapted to receive a spring I4 extending peripherally more than half the circumference of the inside of the groove I3 with such tension that when once forced in place in the groove it will stay therein, but have sufficient tension to frictionally engage the inside wall of the casing "I and groove l3 so that when base i is rotated with respect to the casing 1 the screw ill will feed the plunger II upwardly when rotated in the right direction, the plunger being held from free rotation by the friction between the plunger II and the casing 1, caused by spring I4. By having this spring of suflicient tension I am able to eliminate the spline connections shown in my allowed application above referred to, thereby enabling me to use standard or other tubing for the casing I and still have satisfactory non-rotative connection between casing i and plunger II to keep the latter from rotating to any substantial extent when lipstick material I5, which fills the space in the casing '1 above the plunger II, is being fed toward the applying end of the applicator as needed. It is particularly desirable that the friction caused by the spring be ample so that no rotation will take place between the plunger and casing I in the form which I have shown herein in which the applying end of the lipstick applicator or container is composed of two or more surfaces, such as IB and I1, formed by the shape of the end of the casing serving to provide a ridge I8 of free lipstick material across the body of lipstick material for better application to the lips, such ridge being shown in both Figs. 2 and 3, but this feature being shown and claimed in my allowed application, Serial No. 699,025, Patent No. 2,457,342, mentioned above.

In the use of my invention, the base and container having been assembled as described above, the plunger H is fed downwardly to approach the base I, and when in that position the inside of the container 1 is filled with lipstick, pomade, perfume or other solid or semisolid material. Excess material at the surfaces I6 and H and ridge 48 are then scraped oil so that the lipstick or other material is left flush with this irregular shaped end of the casing, in which condition the device is adapted to be used. As the material at this exposed surface is reduced the casing I may be held by one hand and the base I by the other, whereupon, by slight rotation of these two in the right direction, turning the right hand to the right, as shown in Fig. 2, lipstick or other pomade material will be fed very slowly to the applying end of the casing to replenish what has been used up. In this way sufficient material may be kept flush, or substantially flush, with the applying end of the casing 1 for use. The spring I4 preferably has ample friction with the inside of the container 1 and groove l3 to not rotate therein, and prevents sufficient tendency to rotate the body of lipstick or other po- 6 made material with respect to the casing so as to disalign the ridge [8 from the line connect- 4 ing the corresponding portions of the walls of the casing 'l, which are the determining factors in keeping the ridge of free material across a large portion of the diameter of the pomade material.

It is, of course, not necessary that my invention be limited to applicators in which the applying end of the containers are of irregular shape, as the applying end of the container applicator may be straight across, and generally is made in this way when it is to be filled or used with some forms of pomade or with solid perfume. Even in these cases, however, I prefer to have a sufficiently strong frictional contact between the plunger II and the inside of the casing I so that the plunger II is readily fed to feed material towards the open end of the casing when the base I and screw i0 is rotated with respect to the casing 1.

Having described my invention, what I claim is:

A non-retractable cosmetic applicator comprising a cylindrical tube, a base plug fitting the bottom end of the tube, said plug having a cylindrical portion fitting within the tube and provided with a peripheral groove, the bottom portion of said tube being displaced into said groove and establishing a rotatable connection between said base and tube, a plunger within said tube, screw means carried by said base and threaded through said plunger operable by rotation of said base relative to said plunger for advancing said plungor toward the upper end of the tube, and in which said plunger has a peripheral groove, and in which a split metal ring is located in said groove and frictionally engages said plunger and the inside wall or said tube with sufiicient grip to prevent relative rotation therebetween during operation of said plunger advancing means.
