LIPSTICK CONTAINER Filed July 19, 1949 ZSHEETS-SHEET 2 Patented Mar. 3, 1953 UNITED STATES 9T5 OFFICE 4 Claims.

This invention relates to improvements in lipstick containers, and refers particularly to a lipstick container or case of the swivel type, that is, wherein the lipstick is fed outwardly for use by relative rotation of portions of the casing, the present invention being characterized in that the casing is readily refillable by the user.

The cost of the usual lipstick casing is proportionately high compared to the cost of the complete item and, hence, it would be most desirable to so construct the casing as to have it function as a permanent lipstick receptacle and to furnish cartridges of lipstick. material which could be inserted by the user in the receptacle as a refill as occasion demands.

However, lipstick material, by the nature of its use, necessitates that it be relatively soft and can be easily abraded by rubbing on the lips of the user. This characteristic of the material makes handling of the lipstick material a delicate and often a messy task. If care is not exercised in the handling of the material the soft, brightly colored material may smear the hands or clothing of the operator or be otherwise objeotionable.

Consequently, a refillable lipstick receptacle must be so constructed that the operations involving handling of the refill will be reduced to a minimum in removing the used cartridge and inserting the refill.

Accordingly, one of the important objects of my invention resides in a refillable, swivel lipstick container or receptacle so constructed that the lipstick material refill. or cartridge can be con veniently inserted in the receptacle and the used cartridge removed or ejected therefrom as a simple operation involving a minimum of handling of the cartridge by the user.

Other objects and advantages of my invention will be apparent from the accompanying drawings and following detailed description.

Referring in detail to the drawings, and with specific reference to Figs. 1 to 5 inclusive, 6 indicates a lipstick container or casing comprising essentially an inner tubular receptacle 2, a cover 3, a base i and lower cap 5. The inner receptacle is adapted to contain a lipstick 6 carried in a follower cup 7.

The base i is preferably tubular in shape and formed integral therewith and offset inwardly therefrom is a collar extension 8. Shoulder 9 provided by the ofiset juncture of the base and collar functions as a stop for the lower edge of cover 3 which telescopically engages collar 3. The cover 3 is closed at its top and functions as a closure for the receptacle 2 which carries the lipstick 6.

Receptacle 2 comprises an outer sleeve it, an inner sleeve ll and an intermediate sleeve 12. The outer sleeve 1 t is provided with a circumferential bead l3 adjacent one end thereof and in assembling the device said bead rests upon the upper edge of collar 3, the end of sleeve IE! being telescopically positioned within said collar. The upper edge of the outer sleeve It is flanged inwardly, as shown best at it in Fig. l, to present a finished appearance to receptacle 2 and prevent scratching or injury to the users lips.

The inner sleeve ii is rigidly secured to the inner portion of base 3, being offset inwardly at It (Fig. 1) to form a seat for the edge of in termediate sleeve 22. That portion of inner sleeve H embraced by base t is of double thickness and the sleeve proper as well as the inner Wall 16 of the embraced portion of the sleeve is provided with a longitudinal slot ll disposed parallel to the axis of the receptacle.

Disposed between the outer sleeve It and inner sleeve H is the intermediate sleeve l2 which is constructed of relatively thin resilient metal. As has been hereinbefore described the intermediate sleeve seats upon the offset portion of the inner sleeve, said latter being provided with a circumferential bead i8 adjacent its upper end against which the upper edge of the intermediate sleeve abuts when the parts are assembled. In order to permit the telescopic positioning of the inter mediate sleeve over the bead I8, said sleeve I2 is provided with a longitudinal slot l9 whereby in mounting said sleeve may be sprung sufiiciently to permit clearance over the bead l8. In this manner intermediate sleeve I2 is retained in axial immovable position between the inner and outer sleeves. The outer sleeve I8 is provided with an inwardly struck finger H) which when the parts are assembled engages in slot |9 and renders the outer sleeve l3 and intermediate sleeve |2 rotatably immovable with respect to each other. Sleeve 2 is also provided with a spiral slot 20 which opens at its lower end through the lower edge of the sleeve, the upper end of said slot being closed.

As has been hereinbefore described lipstick 6 is carried by follower cup 1 which is adapted to move axially within receptacle 2. To accomplish this axial movement, follower cup 1 carries a pin 2| which is adapted to register with slots H and 20 in sleeves and I2 respectively. It will be noted that when pin 2| rests in slots IT and 23, relative rotary motion of sleeve II with respect to sleeve 52 will cause the pin to move upwardly through both slots. The arrangement is such that outer sleeve i interengaged with intermediate sleeve is rotatable with respect to inner sleeve I and base 4. In use, base 4 and the upper portion of outer sleeve |D are grasped by the user and the parts are rotated relative to each other to bring about the axial movement of the lipstick.

As a feature of my invention, the lower end of intermediate sleeve 22 is cut away, as shown best at 22 in Fig. 5 providing defining edges 23,

24 and 25. A struckup lug 26 is formed upon one edge defining slot ll in inner sleeve When the parts are assembled the lug 26 is disposed in the cut-away portion 22 of sleeve l2 and during rotation edge 25 rides upon the upper portion of the lug 25. In view of the fact that sleeve i2 and sleeve i are relatively rotatable, such relative rotation is limited in either direction by lug 26 engaging edge 23 or 24. When lug 26 engages edge 24 the open ends of slots I! and 29 will be in register which greatly facilitates the insertion of the lipstick and follower cup in operative position within the receptacle 2.

As has been hereinbefore described, the concept of a refillable lipstick case is most desirable, but in view of the non-mechanical inclinations of the normal users of lipsticks and the fact that a lipstick, at best, is more or less messy to handle, it is necessary that the operation of inserting the refill be most simple and convenient. By the provision of the indexing stop provided by the lug 25 and edge 24 automatically aligning the ends of slots i? and 2D, the operation of inserting a refill in my casing merely involves inserting the lipstick 3 and follower cup in the lower end of the device, having pin 2| register with slot I! in the lower end of sleeve II and with stop 26 in contact with edge 24, the pin is automatically insertable in slot 29. Cap 5 may then be positinned over base 4, said cap being non-rotatable with respect to said base whereby the cap and base turn together. Base 5 may carry coil spring 21 whereby cup 7 will be urged upwardly to maintain pin 2| in its proper position within both grooves I! and 23 when it is initially inserted.

To remove the used lipstick the cup I is retracted in receptacle 2 until pin 2| is at the open ends of slots H and 20 at the time when lug 26 contacts edge 24. The end of cup I may then be easily secured by engaging the fingernails in the groove 28 and cup 1 may be removed, pin 2| passing through the lower end of slot Referring particularly to Figs. 6 to 10 inclusive casing 29 indicates a modification of my invention. The casing 29 comprises essentially a tubular receptacle 3!], a cover 3| and base 32. A lipstick 33 carried by a follower cup 34 is adapted to be positioned in a tubular receptacle 3!! and is movable axially therein.

The base 32 intermediate its height is offset inwardly to provide a shoulder 35 and an upwardly extending tubular member 36 is formed integral with the base 32 and join the base 32 at the offset shoulder 35. The offset shoulder 35 functions as a stop for the lower edge of the cover 3|, said cover telescopically engaging the outer portion of the tubular extension 36.

The receptacle 30 comprises an outer sleeve 31, an inner sleeve 38 and an intermediate sleeve 39. The outer sleeve 31 carries a circumferential bead 48 adjacent one end thereof and that portion of the outer sleeve 31 beneath the bead 49 telescopically engages the interior surface of the tubular extension 3'6, bead 40 resting upon the upper edge of said tubular extension.

The inner sleeve 38 terminates in an enlarged portion 4| at its lower end and is closed at its bottom as indicated best at 42 in Fig. 6. A shoulder 4! is formed between the sleeve 38 proper and the enlarged portion 4|. The base 32 and the enlarged portion 4| are relatively immovable, that is when the base portion 32 is rotated sleeve 33 also rotates. Sleeve 38 is provided with an axial slot 48 which extends from its upper edge to shoulder 47.

Intermediate the outer sleeve 37 and the inner sleeve 38 the sleeve 39 is positioned. Sleeve 39 is provided for a portion of its length with a relatively straight axial slot 49. At the upper portion of the axial slot 49 said slot enters a spiral slot 50 which latter traverses a portion of the circumference of the intermediate sleeve 39. At the upper end of the slot 50, said slot connects with slot 5| which is also a portion of a helix the angle of which is reversed with respect to the angle of the helical slot 59. The slot 5| terminates closely adjacent the upper edge of the sleeve 39.

To insert the lipstick 33 and follower cup 34 into receptacle 30 the outer sleeve 37 is removed from its telescopically engaged position with respect to the tubular extension 36. The outer sleeve 31 and intermediate sleeve 39 are relatively immovable and consequently with the removal of the outer sleeve 32' the intermediate sleeve 39 is also removed. The follower cup 34 is then inserted in the upper end of the sleeve 38. A pin 52 is carried upon the outer surface of the follower cup and this pin is brought into registration with the open upper end of slot 48. The follower cup and lipstick is then moved downwardly into the inner sleeve 38, pin 52 riding in slot 48. A coil spring 53 is positioned upon the bottom 42 of the inner sleeve 38 and the bottom of cup 34 rests upon the upper portion of said spring when the lipstick 33 is inserted in the receptacle 30. The outer sleeve 31 carrying the intermediate sleeve 33 is then positioned over the inner sleeve 38 and the outer sleeve is then rotated. This rotation also rotates the intermediate sleeve 39 and when the lower end of slot 49 engages the pin 52 spring 53 moves cup 34 upwardly so that pin 52 will be positioned in slot 49 in addition to its being positioned in slot 58. This relation of the parts is shown best in Fig. 7.

The device in this position is ready for use and it can readily be seen that by relatively rotating the outer and intermediate sleeves with respect to the inner sleeve 38 cup 36 is moved upwardly through the receptacle 35. When pin 52 carried by cup B l reaches the juncture of slots 55 and 5! in the intermediate sleeve 35, the lipstick 33 will have pins substantially completely used. It can readily be seen that by continued relative rotation of the inner sleeve with respect to the outer and intermediate sleeves no further upward movement of the cup will take place until the relative rotation of the respective parts is reversed at which time pin 52 will travel upwardly through the reverse helical slot 5! until it approaches the upper edge of the sleeve 39. In view of the fact that pin 52 is carried adjacent bottom of cup 3 when said pin moves to the upper extremity of the reverse slot 5! said pin will simultaneously be moved to the upper end of slot at. The upper edge of the inner sleeve 38 is relieved adjacent one side of slot 48 as shown best at 55 in Fig. 10 and consequently continued reverse relative movement of the sleeves will cause the pin 52 to ride upon the upper edge 5 of sleeve 38 and the cup 34 will be canted thereby disengaging pin 52 from the upper end of slot 51. In this manner the cup 34 carrying the used lipstick will be ejected from the receptacle 30.

I am aware that many modifications may be made in my invention and hence I do not wish to be limited except as necessitated by the prior art.
