3 Claims. (Cl. 20G- 56) This invention relates to a new type holder for lipsticks and like cosmetic material which are projected from and retracted into the holder lengthwise as desired. j

The operation of conventional lipstick holders require the usually independent functioning of screw, spring and slidable projection type mechanisms for the advancement and retraction of the lipstick. Such types are of relatively complex and costly manufacture, and'often difficult to operate satisfactorily.

Broadly, the instant invention involves the provision of a cosmetic container having a minimum number of simply designed, easily formed and inexpensively assembled parts and entirely operable by uid pressure. Actuated by a pressure differential, the lipstick or similar cosmetic material may be ejected axially from the holder to a regulated height by the user simultaneously with and in synchronous relation with the removal of an outer slidable cap.

The invention comprises generally in its more specific aspects a slidable outer cap or cover in frictional contact with a lipstick casing having a perforation in the base thereof, said perforation being capable of closure by the positioning and pressure of a finger of the user against the opening. Within and in frictional contact with the casing proper is an elevator unit comprising an inner container holding the lipstick, which unit is slidably mounted in the casing and designed to slidably project lipstick from one end thereof.

For a fuller understanding of the invention, reference is made to the following detailed description taken in conjunction with the accompanying drawing, in which: l

Fig. 1 is a view in vertical elevation of adipstick holder with the closure cap in place, partly Y in section illustrating the variousparts and a lipare used to designate corresponding parts of all the views.

`Referring to the drawing and particularly Figs. 1 and 3 thereof, numeral I0 represents the slidable hollow outer cover or cap preferably completely or partially made of transparent material and Whose open end telescopically lits over the lipstick casing II. The outer closure cap IIJ is preferably cylindrical in shape although it may assume any desired form such as of polygonal (e. g. square or hexagonal) or elliptical design in a transverse cross-section. Its design is such as to provide for the creation of a partial vacuum in the enclosed air space during the course of its removal from the casing II. A friction lit with the complementary engaging surfaces of casing II is therefore desirable when slidable cap I0 is positioned thereon.

The casing or body member II is expanded to form a base I4 preferably having an outwardly projecting flange-like head or rim. suitably disposed or formed in the base I4 is an aperture I5 communicating with the interior of holder I I, which will allow the inrush of air and formation of an air cushion or layer I6 when the elevator unit, comprising the lipstick I2 positioned in the carrier I3, is raised simultaneously and in synchronous relation with the removal of cap I0.

slidably positioned and adapted to move axially by means of fluid pressure within the casing II is such elevator unit consisting at least of a cup or similar container I3 and a lipstick I2 positioned therein. The outer diameter of container I3 is such as to be in contact with the adjacent inner surface of casing II only to the degree required for its axial movement by air pressure differentials, such as a frictional fit.

The entire lipstick unit is operable by num pressure only and as illustrated in Fig. 3 is dependent upon the provision of pressure differentials. As the outer cap is removed, a partial vacuum is created in the enclosed air space in the cap which causes the elevation of the lipstick I2 and inner container I3 simultaneously with and infsynchronous relationship with the cap removal. The movement of the cap I0 and the corresponding movement of the lipstick carrier I3 upwardly will thus ultimately project the body of the lipstick or other suitable cosmetic material beyond the outer end of holder II. Concurrently, air enters the hole I5 in the base I4 of holder II and forms the air pocket cushion I6 inside the holder Il and below the inner container I3. The lipstickl2 and inner container I3 are then fixed in the elevated position by placing a linger over the hole I5 thereby sealing the aperture. When the lipstick is applied to the userthe elevated inner container I3 holding the lipstick proper is cushioned upon the resultant air pocket or cushion I6.

After usage, the finger may be removed from the hole I in the base I4 and the outer cap I6 is replaced upon holder II, which operation depresses the lipstick I2 and inner container or carrier I3 due to the partial pressure inside the downwardly moving outer cap I0. At the same time with the return of the inner container I3 to a resting position upon the interior of holderA II, the air represented by the air Vcushion IB- is ejected through the hole I5 in the base I4.

The simple design, arrangement and functioning of the various partsreadily and advantageously render possible certain optionaloperating modifications. Apart from the lipstick proper, the materials may be of metalfor plasticconfaces is continuously engaged so as to always maintain a frictional factor. This construction may be incurred for example where the walls of the outer cap taper outwardly toward its closed end and the walls of the casing are parallel, whereby a frictional t may be obtained between the vlower-open end portion of the outer cap and the corresponding engaging surfaces of the casing while the outer cap is positioned on the casing and during its removal therefrom.

In addition, thecircumference or periphery of `the casing II at or near its open end may be turned in to act as a stop. so that the elevator or inner container I3 cannot be removed during the elevating operation.

Thus by means of the arrangement and func- .tioning vof the various parts on a iluid pressure struction, or any working combination of suchY as determined by observation during the course of removal of the at least partially transparent outer. cap, the lipstick may be iixed in such desired elevated position by the closure of the aperture in the base of the casing.

Similarly, the casing I I may be constructed of metal, or plastic material,.transparent or other- Wise as. desired. The use of resilient or springy plastic or metal, as for example brass, provides for an alternative means of fixing. the lipstick and inner container in its elevated position during application ofthe lipstick. After the lipstick and inner container are elevated to the desired height for usage, the sides of the casing I I, constructed of a resilient or springy material, may be slightly distorted by applied iingerl pressure, thereby providing an alternative to the use of nger pressure on the air aperture.

This air aperture I5 may be located at any working point on the base I4 of the casing. It may be situated on the inner portion of the flange, or preferably on the periphery of the flange as shown in Figs. 1 and 3. An alternative modincation is the insertion of the aperture I5 on any portion of the outer base as illustrated in Fig. 4. The positioning of the air opening is determined by an integration of the various factors of convenience of use, ease of manufacture, attractiveness, etc. Its position in the base should preferably be identified by an appropriate design, as for example by the use of a bead or a linger depression.

As previously disclosed, the contacts between the outer cap IG and the outer surfaces of casing II, and between the inner surfaces of casing I I and the adjacent sides of the elevator or inner container I3 are such as to have a frictional ralation and create the necessary pressure differentials during operation. If desired a lubricant may be used appropriately on one or both of these iits. The sides of the outer cap III, casing I I and'elevator I3 may be parallel or substantially so preferably. However, if desired these sides may be permitted to taper provided the necessary lits between the complementary engaging surfaces are maintained. It is not necessary that the frictional effect be maintained along the entire adjacent surfaces, particularly with reference to the iit between the outer cap and the casing. It is sufcient if a portion of each ofthe adjacentsurprinciple, no necessity exists for use of operating means of complex and relatively costly manufacture involving the conventional screw, spring and slidable projection type mechanisms. The very simplicity of design of the minimum number of parts of myv container, their easy forma.- tion and assembly consequently render capable facile and inexpensive manufacture.

The physical operations of the user are sim plilied since'the outer cap may be removed .and theflipstick ejected, or the parts restored afterwards to their normalposition, simultaneously without the necessity of maintaining a particular relationship of certain parts manually by the user. For example, with certain projection type lipstick containers, the user must replace the cap in a predetermined manner in order to cause engagement of a particular notch with a projection. With other containers, after the outer cap removal screws, springs, levers, slides, etc. must be operated in a separate and usually independentstep in order to elevate the. lipstick for use. The present device `obviates the need for such distinct procedures, and of course the possible difficulties ande annoyances inherent in the functioning ofrsuch structures.

The invention may be carried out in other specific ways thanthose herein set forth without departing from the spirit and essential characteristics-'of thek invention, and the present embodiments are to be considered in all respects as illustrative rather than limitative, and all coming within the meaning and equivalency range Vof the appended claimsV are intended to b'eembraced therein.
