R. N. HOULIHAN COSMETIC HOLDER Filed Feb. 15; 1940 INVE TOR ATTORNEYS Patented Sept. -23, 1941 UNlTED STATES PAT 2,256,644 cosnm'rro none Rudolph N. Houlihan, Bridgeport, Conn, assigns:- to The Bridgeport Metal Goods Msnniaotnrl s Company, Bridgeport, Conm, a corporation oi Connecticut 7 Claims.
This invention relates to cosmetic holders, particularly oi the type for holding sticks of cosmetic such as lipstlcks, shaving soap, and the like, and which employ a molded plastic material for the cap or cover member enclosing the bodvof the container.
It has been found that in containers of this type employing a cover or cap member of molded plastic material there is a good deal of expansion and contraction of the molded cover or cap. These are generally molded 01 this material in a solid condition and then drilled or bored out to the proper internal diameter to fit over the body or shell of the container. It has been found that such covers may fit all right when applied and then sometime later may be found to be too tight or too loose due to gradual contraction or expansion. It is therefore an object of the present invention to provide a construction for the body or shell of the container in which the contact surface between the shell and the inner wall or the cap is greatly reduced over what it would be with a plain cylindrical outer wall for the shell, and therefore the Irictional resistance between the two members as the cap is slid on or oil of the shell is greatly reduced insuring comparatively easy sliding movement of the cap should this cap have shrunk somewhat, and also to so form the walls of the body or shell that they may yield slightly in case the cap has shrunk so that it may be readily slid oil or slid onto the shell even after changes in the cover.
With the foregoing and other objects in view I have devised the construction illustrated in the accompanying drawing forming a part of this specification. It will of course be understood that various changes and modifications may be employed within the scope of the invention.
In this drawing:
Fig. l is a side elevation of a holder involving this invention with a portion or the cover or cap broken away;
Fig. 2 is a transverse section substantially on line 2-4 0! Fig.1;
Fig. 3 is a similar view showing a slight modiflcation and with the internal operating elements omitted;
Fig. 4 is a perspective view 0! the cap and body members in separated relation;
Fig. 5 is a plan view of the upper end of the holder used for lipsticlss comprising a metal shell or body member it and a cap or cover l l of molded plastic material, a great typeset which plastic material are now available on the market under various trade names and may be produced 'in different colors for difierent artistic efiects. These caps are usually molded as a solid cylinder and then drilled or bored out to the proper internal diameter to slide over the metal body member or shell containing the lipstick to close the open end ii of this shell and also enclose the shell itself as shown in Fig. 1. it has been found that due to the properties of these synthetic molded materials of gradually expanding and contracting after they are made that after a while they may be too large or too small to properly fit the metal shell even though it may have fitted when first made or applied. Thus if it shrinks and the container has stood for some time it may be so tight m to be dimcult to remove, or it may have increased in size so as to become too loose.
I have found that if instead oi making the inner body or shell it cylindrical I make the outer wall of spaced longitudinal extending portions the contact surface between the er shell and outer cap may be greatly reduced over what it would he with a cylindrical shell thus greatly reducing the friction between them should the cap shrink sufliciently to permit removal of the cap, and the outer wall or the shell may also be constructed so that it may yield inwardly slightly under contraction of the cap maintaining an even frictional engagement between the two so that they will not bind. Thus the shell in may be drawn from sheet metal with a series of spaced relatively wide portions 13 extending longitudi' nally for the length thereof withthe connecting walls l4 between them or considerably less diameter, the outer portions i3 being on the are of a circle of substantially the inner diameter of the cap II as shown in Fig. 2, or they may be transversely curved on arcs i5 of somewhat smaller radius than the radius of the internal walls I6 0! the cap as shown in Fig. 3, thus still further reducing the contact surface engaging the inner wall or suriace or the cap and thus still further reducing the friction between them. The curved walls i3 and M 0! Fig. 2 or M and Ii of Fig. 3 are connected by continuous short walls I1, and because of thisarrangementthe outer walls l3 and 15 may yield inwardly slightly un- 'der pressure on their outer walls, the connecting walls l1 bending laterally slightly, which would not be possible were the outer wall a continuous cylindrical wall, and this slight yielding is even more readily secured in the construction shown in Fig. 3 where the radius oi the wall portions 15 is somewhat less than the radius or the inner wall of the cap. Thesame internal operating mechanism for shifting the cosmetic carrier may be usedin the form of'Fig. 3 as in Fig. 2, these elements merely being omitted in Fig. 3 to simplify the drawin In order'to hold the cap "against accidental removal from the shell the shell may be lanced adiacent the inner end of the shell and spring ears bent outwardly as shown at It to yieldingly engage the inner wall of the cap to irictionally hold it in position.
This construction of shell may be used with diilerent types of holders employing different types of mechanism within the shell for holding and carrying the cosmetic stick. present construction I have shown it applied to what is known as the swivel type of holder in which an operating hand piece or head I9 is rotated to advance the lipstick from the open 2.

This resilient or spring sleeve 25 is located at the inner her to hold the cosmetic and open at one end, a
hollow 'cylindrical cover of molded plastic material embracing said body, and said body comprising spaced relatively wide longitudinal side wall portions with the outer suriaces'thereoi forming arcs ofa circle of substantially the same diameter as the inner diameter of the cover, said side wall portions being separated by relatively wide longitudinal channels.
3. A cosmetic holder comprising a body of resilient sheet metal to hold the cosmetic and open at one end, a hollow'cylindrical cover of molded plastic material embracing said body, and said body being provided in its side walls with spaced, longitudinally extending transversely curved raised portions which are relatively wide and I '01 substantially the same curvature as the inner walls of the cover so that the outer curved walls may yield inwardly slightly on pressure from the cover and there is a bearing of material width on the cover.

' outer shell and the inner shell 20. As the shell 25 due to its resilient action tends to expand it frictionally engages the inner surfaces of the curved walls ll of shell ill and is held stationary, these walls ll giving suflicient bearing and friction for this eflect. Therefore as the inner shell 20 is rotated the pin 231s carried along the spiral slot 24 to advance and retract the carrier 2i carrying the lipstick or other cosmetic stick 26. To give a smoother action the sleeve 25 is slotted to provide spring lugs at which are bent inwardly somewhat to irictionally engage the outer surface of the sleeve 2@. Also, the sleeve 20 may have another longitudinal slot 28 spaced from the slot 22 to provide a relatively narrow strip of wall '29 which is forced outwardly somewhat so as to yieldingly engage the inner suriaceof the sleeve 25 to give a frictional bearing and smooth even operation of the inner shell.
This shell may have an outwardly extending bead 30 at its upper end under which the upper end of the sleeve 25 engages to hold them in assembled relation. As above indicated, however, it is to be understood that this inner mechanism for advancing or retracting the lipstick is merely shown by way of example and to illustrate a complete article, but that other types of operating mechanism may be used with this improved outer shell construction. Also, the same internal mechanism for shifting the cosmetic carrier may be used in the two forms of Figs." 2 and 3.
Having thus set forth the nature of my invention, what I claim is:
1. A cosmetic holder comprising a body mem- 4. A cosmetic holder comprising a hollow "sheet metal body and a hollow cylindrical cover embracing said body, the side walls of said body Y comprising relatively wide longitudinally extending alternate depressed and raised portions of substantially equal width and with the outer surfaces of the raised portions transversely curved of substantially the same curvature as the inner wall 'of the cover to engage the inner wall of the cover and provide a bearing of material width on the cover but with much less contact surface with this wall than would a continuous cylindrical surface of the same di N -ameter. l
portions each comprising spaced relatively wide arcs of a cylinder with one of a greater diameter than the other, and each arc of one portion being between two arcs of the other portion and connected at its edges to the arcs of the other portion by connecting walls, and the arcs of the outer portion being in a cylinder of substantially the diameter of the inner wall of the cover.
