13 Claims. (Cl. 20656) My invention relates to a cosmetic-container construction and is particularly concerned with such constructions in which the closure cap is frictionally retained when placed over the container body.

-It is an object of the invention to provide an improved construction of the character indicated.

-It is another object to provide an improved cosmeticcontainer construction, characterized by relatively easy action in the placement and removal of a closure cap.

It is a further object to meet the above objects with a construction featuring reduced axial play and improved smoothness of action in the propulsion of a cosmetic.

It is still another object to meet the above objects with a construction in which the placement of the closure cap inherently tends to more tightly frictionally engage relatively rotatable parts, whereby inadvertent propulsion of the lipstick is avoided while the closure cap is in place.

It is another object to meet the above objects with improved means for frictionally engaging a closure cap to a container.

Other objects and various further features of novelty and invention will become apparent or will occur to those skilled in the art from a reading of the following specification in conjunction with the accompanying drawing-s. In said drawings, which show, for illustrative purposes only, preferred forms of the invention:

Figs. 9 and 10 are similar vertical sectional viewsto illustrate still further modifications.

Briefly stated, my invention ina preferred form contemplates improved means for frictionally retaining a closure cap when'placed over the body of a cosmetic container. My friction member is characterized particularly by a generally conically developedoutwardly flaring skirt, retained by the container body and flaring freely outwardly, to an extent permitting resilient interception of the bore of the closurecap as the latter is placed over the container. The small end of the skirt is retained on the container'body, as against a'circumferential head, or by forming said small end with a radially flange is axially'deflected, thus increasing theaxial load inwardly extending portion located vin a groove or bea 25,840,229 Patented June 24, 1958 ice inwardly extending. portion is so formedas to serve certain further functions, particularly useful in swivel-type or self-propelling'lipsticks involving inner and outer rela tively rotatable tubular body elements. The nature of this inwardly extendingportion is such as lightly axially to load the relatively rotatable parts and thus eliminate rattle or axial play therebetween. The nature of my constructionis further such that,- upon placement of the closure cap, the skirt is inwardly deflected and the radial on the .relativelyrotata'ble parts and providing increased friction, for resistance of inadvertent rotation of the parts when the container 'is closed.

-Referring'to Figs. 1 and 2 of the drawings, my invention is'shown in application 'to a swivel-type or selfpropelling rotary lipstick container, comprising inner and outer sleevefmembers -1011 having cam slots 12-13 formed therein for engagement with the follower 14 of a carrier cup 15, for, a'lipstick -or-the like 16. In the form shown,'a jcircumferentialtbead 17 constitutes a radially outwardyflange or limiting means for axially locating one end of'the outer tubular member 1-1, and a radial flange or shoulder 18 limits or axially locates the other end of the outer tubular member 11. The inner tubular member is completed by a cylindrical land 19 connecting the shoulder 18 to an enlarged base or actuating-knob portion '20, constituting the closed end of the inner tubular member 10. For appearance sake, I have provided a casing 21 to retain the outer tubular member or sleeve 11, and I show a snap lug 22 formed out of thecasing 21 and projecting inwardly tO-engage a corresponding hole 23 in the sleeve -11, for' holding thepa'rts together.

In accordance with the invention, I provide a resilient skirt or circum-ferentially extending member 24 carried by the'container body in such manner as to position a free outwardly extending lip '25 thereof in intercepting relation with the bore o'fthe'closure cap 26 to be placed over the open end 27 of the container. The maximum "unstressed outer diameter of the skirt portion 25 preferably exceeds the bore diameter-of the closure cap 26, so that placementof the cl'osure cap will be accompanied by radially inward deformation of the skirt 25, with resultant light, easy-acting frictidnalengagement of the parts and retention of the closure. cap. The parts are-shown in 'Fig. 2 in their relationship when the closure cap 26 has been placed into .fully assembled relation with the base 20 and in abutment with the shoulder 28 thereof.

The resilient' rnember 24 may be of gently yieldable material, such as polyethylene oran equivalent plastic, and preferably includes, in'addition to the skirt 25, means formed integrally with the small end thereof and extending genera-l ly radially inwardly, for axial location by the retention means formed 'on the body of the container. In the "form 's'hown,.-the radially inwardly extending part is {a 'ra'di'al flange -29, so formed as to seat on theshoulder 18 and to substantially close off the axial clearance between shoulder 18 and the sleeve and casing 1"121. "Theradially extending flange 29 is preferably somewhat =frusto=coriically formed, -eve n' in the =unstresse'd 2c0ndition shownfinFig. 3, and may be viewed as a dished resilient washer, lightly' loading" the parts 1-1 2 1 to eliminate axial pla'y. "Fig. 4 shows that when hood of cosmetic damage due to inadvertent propulsion against the. inside of the closure cap is rendered remote.

The modification shown'in Figs. 5 and 6 difiers from the described form of Figs. 3 and 4 only in that the radial-flange portion .29 is, in effect, a peripheral succession of similar radially inwardly directed .lugs .-31, defined by radial serrations or slits 3 2. I It will .be' appreciated that provision of slits 32 may, 1 for certain materials and material thicknesses,,promote greateraxial distention of the. radial flange 29. and, therefore, added frictional loading of the relatively rotatable parts, when the skirt 25 is radially compressed by a closure cap, as shown in Fig. 6. a I

In Fig. 7 I illustrate a circumferentially extending member 24 which may, in all respects, resemble the member 24 of Figs. 3 and 4, except that I provide a reinforcement or stiffening member 33 carried by or molded within the body of the, member 24'. Stifiening member 33 may be one of an angularly spaced plurality, but I have shown only one such member. Member 33 extends forsubstantially the full axial length of the skirt 25 and for substantially the full radially inward extent of the flange 29. It will be appreciated that, upon placement of the closure cap over the skirt 25, with accompanying radially inward. deformation of skirt 25, the reinforcement member. 33 will serve as a bellcrank, undergoing partial clockwise rotation inthe sense of Fig.

.7, and more positively driving a local portion of the radial flange 29 into frictional engagement with the adjacent axial end of the sleeve or casing 1121.

For situations in which the peripheral friction-engagement function is not important, the member 24' may be viewed merely as a means for flexibly supporting the bellcrank 33. The axially extending arm of bellcrank 33 projects outwardly for interception by the closure cap, and.

the radially extending arm thereof is driven axiallyinto frictional engagement with parts 11=21'when the closure cap is placed over the container. 3 r

In Fig. 8, I show application of my invention to another construction in which peripherally continuous friction engagement may not be. an important requirement,

deformation, and that the. radial flange 29 shall be conically dished, and thereforelightly axially loaded against parts 1 121, as explainedabove in connection withotherfigures. 1y

, In the container of Fig. 9, the lipstick tor the like is held in a carrier 40 havinga finger-actuating piece 41,

accessible externally through a guide slot 42, in the single I 1 tubular body member43 Forassembly purposes, the upper end 44 of the slot 42 is open; the lower end of the body 43,.is preferably closed by anenlarged base 45., My resilient skirt is shown to be formed integrally with a radially inwardly extending portion 47 for axial 'locationbetween the walls or flanges 4849,'

.of Fig. L9,,andgaretherefore given the samereference numbers, ;but ;with primed 1 notationflThe' unstressed minimum radial dimension of member .56; is1 preferably slightly lessthanthe outer'diameter of the, land .50,

so that even though axially retained by head 55, member 56 will tend to resiliently hug the land 50'. Frictional engagement with and reterition of the closure cap 51 are otherwise as described for Fig. 9.

It will be seen that I have described a relatively simple container construction having features of smooth frictional engagement of the closure cap, without develop ment of undue stickiness in the placement or removal of the closure cap. My mechanism is such that axial play may be avoided between the relatively rotatable parts, and yet rotation is easy and smooth when dispensing or retracting the lipstick, Nevertheless, upon placement of the closure cap, not only is the aforementioned friction engagement developed, but the parts are inherently frictionally loaded or lightly jammed against inadvertent rciativerotation displacement, so that contact of the lipstick with the inside of the closure cap may be avoided.

'While I have described the invention in detail for the preferred forms shown, it will be understood that modifications may be made within the scope of the invention as defined in the claims which follow.
