UnitedStates Patent COSMETIC CONTAINER William James Landen. Cheshire, Conn., assignor to Eyelet Specialty Division, The International Silver Company, Waterbury, Conn., a corporation of Connecticut Filed Mar. 31, 1958, Ser. No. 725,423

4 Claims. (Cl. 20656) This invent on relates to an improved cosmeticcontainer construction. and is particularly concerned w th configurations in which a decorative external case (with removable closure cap) is adapted to remov blv receive a selected one of a number of various cartridge assemblies.

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

It is another object to provide an improved c rtridge construction for contaners of the character indicated whereby, once inserted in the decorative case, the cartridge may be locked positively against axial separation from the case.

It is also an obiect to provide a cartridge meeting the above objects and having manually actuable means for readIly separating, that is, for unlocking the engagement between, the cartridge and the case.

Other objects and various further features of novelty and invention will be pointed out or will occur to those skilled in the art from a reading of the following specification, in conjunction with the accompanying drawings.

In said drawings, whch show, for illustrative purposes only, a preferred form of the invention:

Fig. 1 is a longitudinal sectional view of a cosmetic container embodying features of the invention, with certain parts broken away to reveal internal details;

Figs. 2, 3 and 4 are enlarged sectional views taken in the planes 2-2, 3-3, and 4-4, respectively of Fig. 1;

Fig. 5 is a fragmentary view in side elevation of the lower part of the cartridge of Fig. l; and

Fig. 6 is a view in perspective of the lower part of the decorative case shown in Fig. 1.

Briefly stated, the invention contemplates an improved cosmetic-container construction in which a complete cosmetic-cartridge assembly is removably insertable in the body of an outer decorative case. The cartridge is of the rotary-propulsion variety and includes relatively rotatable base and sleeve parts. The body of the decorative case also includes relatively rotatable base and sleeve parts. Both sleeve parts are of non-circular cross-section, the cartridge sleeve being receivable in the case sleeve, so that the sleeve parts are non-rotatable with respect to each other. The base of the cartridge and the base of the case include interengaging means whereby rotation of the base of the case transmits rotary motion to the base of the cartridge in order to effect propulsion or retraction of a lipstick or the like, as desired. It is a feature of the invention that the two sleeve parts include snap-acting detent means to hold the parts in assembled relation.

Referring to the drawings, the invention is shown in application to a cartridge assembly 10 insertably receivable within the lower part (Fig. 6) of an outer decorative case which is closed by a removable closure cap 11. As best shown in Fig. 6, the lower part of the decorative case comprises an elongated tubular body 12 having a non-circular upper open end, which in the form shown happens to be generally oval in cross-section. The other end of the tubular member 12 is closed by an actuating "ice member 13 journalled for rotation therein. In the form shown, the lower end of the body or sleeve member 12 is of circular cross-section and overlaps a reduced cylindrical part 14 of the base or actuating member 13. A circumferential groove 15 in the cylindrical portion 14 receives lugs or other retaining means 16, struck radially inwardly from the material of body 12, in order to axially retain the parts 12-13 and at the same time to permit free relative rotation thereof.

While the closure cap 11 may engage any convenient part of the case assembly shown in Fig. 6, I prefer that cap engagement be made frictionally to the base or the actuating member 13, as by riding upon one or more friction ridges 17 integrally formed thereon. A radial shoulder 18 on the base member 13 provides a convenient stop to assure complete closure upon placement of the closure cap 11, as will be understood.

As indicated generally above, the cartridge 10 is of the rotary-propulsion variety. Its externally accessible parts compnse an elongated sleeve 20 and the base or actuating member 21 journalled for rotation in the lower end.

.The base or actuating member 21 is shown to be polygonal (see Fig. 4) and to conform with a polygonal socket 22 in the base or actuating member 13, forming part of the decorative case. The cartridge sleeve 20 preferably has a free-sliding fit within the bore of the body 12 and also preferably conforms to its contour, i.e. oval, in the form show-n.

The cartridge 10 includes mechanism cooperating upon relative rotation of the base and sleeve parts 21-20 to propel and retract a lipstick or the Lke 23, which may also be of oval cross-section and supported in an oval carrier cup 24 slidably received in the bore of the sleeve 20. In the form shown, both the carrier cup 24 and the base button 21 are of molded plastic and are integrally formed with interfitting threaded propulsion parts, the cup 24 being formed with a threaded stud 25, and the button 21 being formed with an internally threaded tubular part 26 in constant engagement with the threaded stud 25. A circumferential groove 27 receives the inwardly turned lower lip of the sleeve 20 in order to permanently retain the parts 20-21 in assembled relation.

In accordance with a feature of the invention, the sleeves 12-20 include cooperating elements for releasably holding an inserted cartridge in the lower part of the decorative case, namely, the assembly shown in Fig. 6. Various forms of detent mechanism may be employed for this purpose, but I indicate my preference for a releasable lock of the variety disclosed in copending Isele application, Serial- No. 674,460, filed July 26, 1957, now Patent No. 2,838,170. This type of lock involves a lug 29 struck outwardly from a resiliently deflectable member or part 30 of the cartridge sleeve 20, and in the form shown the deflectable part 30 is defined between two parallel elongated slits or lancings 31-32 in the sleeve 20, so as to permit integral connection of both ends of member 30 to the body of sleeve 20'. As best shown in Figs. 1 and 5, the locking lug 29 is receivable in one or the other of two diametrically opposed locking apertures or windows 33-34 cut in the case sleeve 12, near the open end thereof. For an oval-shaped cartridge-andcase engagement as shown, I prefer that the slits 31-32 and locking lug 29 (as well as openings 33-34) be formed on the flat sides of the oval, as shown in the drawings.

When the cartridge 10 is fully received in the lower part of the case (Fig. 6), it will be noted that a portion of the deflectable member 30 extends beyond the upper end of the case sleeve 12. This relationship is suggested by phantom line 36 in Fig. 5, representing the upper limit of the sleeve 12 (when the parts are assembled, and when the locking lug 29 engages one or the other of the locking apertures 3334). The exposed part of member 30 thus provides a means for finger-access to permit radially inward resilient depression of the member 30 to dislodge the locking engagement at 29-33. In order to facilitate unlocking, I show formation of an outwardly deformed or bulbous projection or thumb piece 37.

When the loaded container is closed, the only externally accessible parts are the decorative closure cap 11 and the enlarged circular bottom 40 of the actuating member 13. These parts may be of any desired shape, depending upon the non-functional design requirements of the customer. When the closure cap 11 is removed, the lipstick may be propelled and repelled, as needed, merely by grasping the sleeve parts 1220 alone or together in one hand, and by rotating the actuating member 13 with the'other hand; A simple thumb depression of the bulbous projection or thumb piece 37 disengages the lock at 2933, so that the cartridge may be removed and replaced with another as desired, eg for changing lipstick shades.

It will be seen that an improved cosmetic container hasbeen described in which replaceable cartridges are readilyinsertable in a decorative case, and yet in which there-may be positive assurance against inadvertent or other separation of the cartridge, particularly in the presence or rough handling or Vibration, as during shipment of loaded containers. The deliberate act of first squeezing the exposed thumb piece 37 is necessary before the cartridge can be removed.

While the invention has been described in detail for.

the preferred forms illustrated, it will be understood that modifications may be made within the scope of the invention as defined in the claims which follow.
