-16 Claims.

This invention relates to 'cxpellant containers for holding, projecting, retracting and applying bodies or sticks-of medicinal, hygienic, cosmetic, marking or other dispensible substances, all of which for convenience hereinare exemplified "by lipstick.

.Animportant object of the invention is to .reduce the thickness of .the complete wall structure, which houses and surrounds a lipstick with its carrier, to preferably a single-ply wall forming a simple shell entirely rid of any extra inner sleeve or sleeves surrounding the retracted lipstick and its carrier. Such extra sleeves heretoforehave been considered .a necessary part of mechanism capable of projecting and retracting the lipstick. Elimination of such extra sleeve enables ta :lipstick of optimum diameter to be housed within and .mechanically projected 'outward :from .a container of minimum overall diameter. Viewed conversely, a smaller overall size of housing is enabled to contain and pro-- .iect a lipstick of larger diameter than has heretofore been possible.

Another object is toconfine all'ef the mechanical core :parts, whichserve to motivate the lipstick carrier, to a location intermediate one end of the outer casing and the nearest end-of the carrier. 1

A further object is to make use of telescoping parts to transmit movement from a hand operated ferrule that is externally exposed for manipulation to a carrier for the lipstick that is slidable lengthwise inside of th casing.

:A further object is to shape such telescoping parts tot-have interen-gaged flat sides so that they may transmit turning movement to one another while sliding telescopically and without resorting to splines, keys, or the like so that said parts may consist of simple, smooth-walled, tubular members.

A further object is to construct an assembly of sucht'elescopic'pa-rt in a manner'to limit the extent of operative separation of the parts by means of 'interengaging "flanges at the terminal edges .oi'. mutua1ly overlapping tubular members.

A still iurtherobject :is to assemble interlockingly an outside iferrule, exposed for imanipu'lation, with acne end of the outer casing so that theserpartswshal-lbe :iree for relative rotary movement.

The above described and other feature of the invention will become clear'in greaterdetail from the following description of representative-embodiments, in which description reference is had to the accompanying drawings, wherein:

Fig. 1 :shows a holder :and container for hpstick incorporating the present [improvements heldin a single hand of .theuser in a :manner .to operate it for projecting, retracting-and applying lipstick without assistance from the userl's other hand.

Fig. 2 is a view drawn on a much enlarged scale showin-gthe assembled holderand container in vertical central section with the lipstick projectin'guready .for use.

Fig. 3 shows vtheparts of Fig. 2 on a reduced scale and collapsed to a position wherein :thelipstick is :housed within its holder and covered by ausual form-of removable cap.

Fig. .4 is an-exploded view of the Working parts of'the stick holder and -container before assembly.

Fig. 5 is a view'taken in cross section on the plane '55 in Fig. 3 looking in the direction of the arrows.

:Fig. 6 is "-a view similar to Fig. 3 showing a modified construction-0f certain telescoping parts.

The parts shown in the drawings maybe 'composed of any of the many available plastic ma terials in molded or extruded form, or some or all of such parts may be made of other materials such .as metal, or workable paper stock shaped by drawingstamping or bend-ingsheets thereoi, or :by casting or otherwise shaping the material to be used.

The outer casing l-El, beioreassembly is a cylind-rical shell-open at both ends. .Its bottom'end is provided with an external annular bead -or circumferen-tialfiange H while its top end is chamvfered at E2 to receive the slip-on cover cap 43-. A helical grooveor thread I9 is sunk in the .internal face of casing Ill which groove is deadended at 29 near (the top of the casing but opens freely out through the bottom end-of the casing so that ferrule l6 and casing ID are thereby held together longitudinally and yet free to swivel relatively to each other. The opposite or bottom end of ferrule I6 is closed by an end wall l1 facing the central well i'i. Upstanding fixedly from end wall or cross wall I! centrally of well l1 there is a driving post Hi. In the form here shown, post I8 is square in cross section and hollow to save material, but may be of any preferably polyhedral shape. Ferrule I6 is larger in diameter than casing shell Ill so as to be grasped independently of such shell as shown in Fig. 1. v

It is believed to be new in these improvements that the plunger or cup-like carrier 25 for the stick 30 of cosmetic or other applicative substance lies directly next to and slidingly fits the helically grooved inner cylindrical surface of the wall of casing ill and is guided by direct contact therewith throughout the extent of its reciprocative travel lengthwise of the container. Fixed on this carrier is the usual projecting lug 26 which slidingly rides in and is guided by helical groove IS without passing through any sleeve intermediate the carrier and outer casing. v Grove l9 and lug 26 are illustrated as one of many varieties of screw thread and follower that might be employed constituting interengaging instrumentalities carried partly by the plunger 25 and partly by the shell Ill.

The mechanical parts which act to project and retract the lipstick carrier 2-5 are herein newly confined to a location between the bottom end of casing Ill and the nearest end of carrier 25. This eliminates what was formerly considered the necessity of interposing a rotatable driving sleeve for lug 26 between the carrier and the adjacent side wall of casing Hi and thus permits substan tial reduction in the overall girth or outside diameter of a casing that is capable of holding a lipstick of any given girth or diameter.

In the construction of the carrier actuating parts herein shown, rotation of ferrule I is transmitted to carrier 25 in both rotary directions through a telescoping mechanism which may or need not include the longitudinally slidable tele scopic tubular coupling 2! which is open at both ends and square in cross section. As shown in Figs. 2, 3 and 5, this coupling slidingly overlaps driving post [8 and is in turn slidingly overlapped by a hollow shank 23 which depends fixedly from the cylindrical body 29 of carrier 25 and which is square in cross section. The hollow in shank 28 may or need not open at its top end into the cup-like space in cylindrical carrier body 29 in which the lower end of lipstick 30 is seated on the annular internal carrier shoulder 3|. However, where lipstick 39 is thus exposed to the hollow in shank 28, the coupling tube 21 if made longer than herein shown may serve to push upwardly on the bottom end of the lipstick and thus act to eject or dislodge a short butt of unconsurned lipstick from its seat in carrier 25 when the parts assume their fully collapsed relationship indicated in Fig. 3.

The extent to which carrier 25 may be moved axially away from driving post i8 is limited jointly by the slide stopping engagement of outward turned lips 35 at the top end of post l8 with inward turned lips 36 at the bottom end of coupling tube 21, and by the slide stopping engagement of outward turned lips 3! at the top end of tubular coupling 2! withthe inward turned lips 38 at the bottom end of carrier shank 28. In view of the similarity of the carrier movement to that of a plunger, the carrier is sometimes so referred to herein.

More than one tubular coupling such as 21 having stop lip as 36, 31 may be interposed telescopically between driving post 18 and carrier shank 28, while Fig, 6 shows a modified construction wherein all tubular couplings such as 21 may be omitted and the lengthened shank 23' of the modified carrier 25' made directly to overlap telescopically the lengthened driving post 18 of the modified ferrule It. It will be understood that in Fig. 6 the modified carrier 25' is provided with the usual lug 26' riding in the helical groove IQ of the casing Ill. The casing can be made proper in length to accommodate the relationship of lengths of post l8 and shank 28 and as dictated by the length of lipstick it is desired to house within the container. Also Fig. fi illustrates that the driving post and carrier shank may be cylindrical instead of polyhedral, either the post or the shank being provided with a longitudinally extending slot or groove 33 slidingly engaged by a tongue-like extension 40. Such groove and tongue may be carried either by the post or by the shank respectively. A corresponding slot and tongue construction may be employed to prevent tubular coupling 21, if made cylindrical, from turning relative to either or both the post or shank.

In further possible modifications not shown in the drawings the stepped order of sizes of the telescopically related elements may be reversed, the ferrule post it or it having the largest cross sectional size and each telescopic part above it having a sufficiently smaller cross sectional size to collapse into positions inside of the post l8 and be overlapped thereby.

The above described parts may conveniently be assembled by preforming the lips 31 and 38 which will leave the lips 35 and 36 to be turned over after assemblage.

In operation my improved lipstick holder may be held in the hand of the user somewhat as shown in Fig. l with the bottom ferrule clutched between the palm of the hand and the second or third finger, while the thumb and index finger of the same hand is left free to swivel the casing shell it about its own axis relatively to ferrule l6. Thus the lipstick can be caused to move back and forth between its projected position in Fig. 2 and its retracted position in Fig. 3. Also with the container so manually held, the extent of projection of the lipstick beyond the open mouth of the casing shell can be maintained or varied while the lipstick is being applied. Other features of the operation will be clear from the foregoing description.

It will be evident to those skilled in the art that parts difiering in shape, size and arrangement from those herein shown can be arranged to operate on similar principles and yield the advantages arising from the particular construction herein illustrated to explain the invention and that the appended claims accordingly will be understood to comprehend and to be directed to all fair'equivalents for such construction as would be suggested by the disclosure hereof.

The reduction of the complete casing wall structure of a 1ipstick holder to a single integral thickness i particularly important in holders for lipstick molded from plastic materials because of the somewhat greater thickness of a tubular wall that is necessary where such mate'- rial is involved.
