Fig. 5 is a bottom view of the embodiment shown in Fig. '4, as seen from the line 5-5 of Fig. 4;

Fig. 6 is 'a view similar to Fig. 4 and illustrates a further modified embodiment of the present invention,-

Fig. 8 is a view similar to that of Fig. 3 showing the embodiment of Fig. 7 in a different position and with cover for the casing removed.

Referring now to Figs. 1-3 in detail, there is shown a housing 10 for a lipstick refill cartridge 12 provided with a lipstick -14, pursuant to the present invention. The housing 10 comprises a casing 16, in which therefill cartridge 12..is contained, .and a cover 18 for closing the casing. The cover. 18 is constitutedby a cylindrical member, preferably formed of a suitable metal orother useful material,- which has a closed end 20 and an open end defined by a marginal end rim 22.

, The casing 16 is constituted by the telescopically related cylindrical sleeves 24' and 26 each formed preferably of a suitable metal, plasticor other-material; the inner sleeve 24 being disposed within theouter sleeve 26. The inner sleeve is open at both ends thereof, its outer. endbeing defined by an inturned peripheral flange 28 and its inner end being defined by a marginal end rim 30. Upwardly from its inner end30, the inner sleeve is provided, on its :outer surface, with an integral circum; ferential collar 32. Downwardly from its'outer end 28, and upWai-dlyfromthe snarsz, the inner sleeveis provided on its inner surface with an integral inwardly directed circumferential bulge 34, the function of which is hereinafterdescribed.

The outer sleeve 26 is open at both its ends. its

lower or outer end is defined by" a marginal end rim 36 provided at the free end of the sleeve portion 38 of enlarged diameter. The upper or inner end'of the outer mined structure so 'asto transform the same into an ejector-type lipstick case pursuant to this. invention.

The "above" andother objects ofthe invention will bei' come furthersappaljent' from theqfollowing detailed de-.

'scription, reference being made to the accompanying V drawings, showing preferred embodiments of the invensleeve is defined by a'n integral outwardly directed circumferential bulge 40 provided adjacentthe free end of the reduced diameter sleeve portion 42. The

sleeve portrons

The lipstick refill cartridge 12 is ofconventionalconstructiori'and is well knownin the art so that detailed descriptionthereof'is deemed; to be unnecessary. As here shown,therefill cartfidge comprises a cylindrical cup -50 in' which the lipstickl l'is mounted. The cup is mounted forrelative movement in an inner sleeve 52, having an open outer end-'54 and provided at its closed inner "end'with the footpiece 56.; A compression spring 58,

Outer end 5.4' normally comes to abut against inner flange 2s. I L 'Theinner. sleeve 52 is mounted for relative movement within.anouter sleeve etl' which has a lower marginal end-62 which abuts thefootpiece 56 and an-upperopening, defined by an upper marginal end 64. It "will be understood thattheinner sleeve 52 is coupled in conventional fashion,yas shown at 66, to the outer sleeve -60,

and the cup 50 is coupled inconventional fashion to the inner. sleeve .52, whereby relative rotation' tof the inner and outer sleeves and 60 will result inmovement of the'cup SOfldn'gitudinalIy ofthe inner sleeve for-projecting the lipstick 14' through the opening defined by the circular flange 28 inthe casing 24 or for retracting the position the latter within the casing. The bulge 34 of the inner casing sleeve 24 is in frictional engagement with the outer sleeve of the cartridge and the friction ring 46 in the outer casing sleeve 26 is in frictional engagement with the footpiece 56 provided on the inner sleeve 52 of the refill cartridge.

Consequently, if the operator holds the inner casing sleeve 24 and rotates the outer casing sleeve 26 relative thereto, the inner cartridge sleeve, which is frictionally coupled to the outer casing sleeve will rotate relative to the outer cartridge sleeve which is frictionally coupled to the inner casing sleeve, whereby to effect the described movemcnt'of the lipstick 14 for projection from, or retraction into the casing. The spring 58 tends to facilitate the projection of the lipstick. The spring 48 tends 'to retain the casing sleeves in the operative disposition thereof illustrated in Figs. 1 and 2 by urging the collar 32 into abutment with the shoulder or detent 44. The outer bulge 40 on the outer cartridge sleeve serves to frictionally engage the casing cover 18 to retain the latter in releasable frictional engagement on the casing.

Pursuant to an important aspect of the present invention, the lipstick cartridge can be ejected positively from the casing without the necessity of first releasing therefill from the casing and then pulling it out by hand from the casing. It will be apparent from Fig.2 that the lipstick cartridge is retained linearly within the casing due to the engagement of bulge 34 with the outer cartridge sleeve and the engagement of the friction sleeve 46 with the footpiece 56 of the inner cartridge sleeve.

Upon telescoping the inner and outer sleeves of the casing, as shown in Fig. 3, the footpiece 56 of the refill cartridge is positively projected from the casing due to the force exerted by the inner end 30 of the inner casing sleeve against the footpiece to project and expose the later, as indicated by the arrows 68. 'Thereupon, the car- ,tridge may be removed from the casing, as will be readily apparent, and as shown by broken line in Fig. 3. When the cartridge is removed, the casing parts remain in the relative positions thereof shown in Fig. 3, since the compressed spring 48 cannot overcome the, friction between the casing parts. However, when a new cartridge is inserted into the casing, through the lower end 36a thereof, the casing sleeves are restored to the operative condition thereof,'shown in Figs. 1 and 2, the compressed spring 48 expanding to facilitate the restoration of the sleeve positions which are properly disposed by the engagement of the collar 32 with the shoulder 44. The flange 28 serves as a positioning detent to properly locate the cartridge within the casing, as will be apparent from Fig. 2,. due to the engagement of the outer end'of the outer cartridge sleeve with the flange.

Referring now to Figs. 4 and 5 in detail, there is shown another embodiment of the invention. It will be understood that in the present embodiment, the refill cartridge is the same as that previously described. The casing 16A is constituted by the telescopically related inner sleeve 70 and outer sleeve 72. The inner sleeve has an outer open end defined by an inwardly directed flange 74 and an inner open ,end' defined by the circumferential collar 76. The outer sleeve 72 has a lower sleeve portion 78 of enlarged diameterand an upper sleeve portion 80 of reduced diameter.- The lower open end 82 of the outer sleeve is provided with an inner friction ring or sleeve 84 suitably secured to the inner surface thereof. An inwardly directed shoulder 86 is defined between the upper and lower portions of the outer sleeve ofthe casing. A cover 18 can be mounted on the casing 16A by frictional engagement with the outer surface of the upper sleeve pgrtion 80, the upper'surface of the shoulder 86-serving 4 as a detent for the cover in the same manner as the shoulder 44 in Fig. l.

With the refill cartridge in position within the casing 16A, the outer sleeve 60a of the cartridge is frictionally engaged with the inner surface of the inner casing sleeve 70 and the footpiece 56 provided on the inner cartridge sleeve is frictionally engaged with the friction ring 84.

Consequently, it will be readily apparent that relative rotation of the casing sleeves will result in relative rotation of the cartridge sleeves for projecting the lipstick from the casing or for withdrawing the latter into the casing.

In order to eject the cartridge from the casing in a positive manner, it is necessary only to telescope the sleeves of the casing. When this is done, the inner sleeve collar '76 will be moved into engagement with the opposing surface 56b of the footpiece 56a so as to eject the cartridge from the casing, in the same manner aspreviously de scribed in connection with Fig. 3, whereupon the cartridge can be readily removed from the casing without soiling the fingers or clothing of the user. The casing parts remain in telescoped position in which the collar 76 abuts the friction ring 84, and when a new cartridge is inserted into the casing, the sleeves thereof are restored to the condition thereof illustrated in Fig. 4 with the collar 76 abutting the shoulder 86 and the cartridge abutting flange 74 to properly position the casing parts and the cartridge within the casing, as shown in Fig. 4.

Sleeves

82, 84 and footpiece 56a of refill cartridge are of quad rangular shape as seen in Fig. 5.

Referring now to Fig. 6 in detail, there is shown an additional embodiment of the present invention. It will be noted that the present embodiment combines features of the embodiments shown in Figs. 1 and 4. The casing 16B of the present embodiment is provided with the telescopically related inner and

outer casing sleeves

88 and 90, respectively. The inner casing sleeve 88 is similar in all respects to the inner casing sleeve 70 of Fig. 4 except that it is provided with an inner surface friction bulge 34, as in Fig. 1, for frictional engagement with the outer cartridge sleeve 60, as shown in Fig. 2. The outer casing sleeve 90 is similar in all respects to the outer casing sleeve of Fig. 1, being provided with an upper end friction bulge 40 for frictional engagement with the cover 18, and an inner surface friction ring 46 for engagement with the cartridge footpiece 56. Consequently, it will be apparent that relative rotation of the casing sleeves will effect the movement of the lipstick 14 as previously described.

In order to etfect the positive ejection of the cartridge from the casing, the casing sleeves are telescoped, whereupon the inner sleeve collar 76 will engage the opposing surface rim 560 of the footpiece 56, as previously described in connection with Fig. 4 to project the footpiece 56 from the casing for removal of the cartridge therefrom. The casing sleeves are restored to their operative position, as shown in Fig. 6, upon reinsertion of a new cartridge in the casing, as described in connection with Fig. 4.

Referring now to Figs. 7 and 8, there is shown a further embodiment of the present invention. Pursuant to the present embodiment, provision is made for a casing comprising the telescopically related inner and

outer sleeves

92 and 94, respectively. Sleeve'92 terminates in an outer, open end defined by the inwardly directed flange 28 and an inner open end defined by the outwardly directed flange 96. The outer sleeve 94 has a lower sleeve portion 98 of enlarged diameter which terminates in an open end defined by the inwardly directed flange 100 and an upper sleeve portion 102 of reduced diameter which terminates in an upper end opening defined by the inwardly directed flange 104. A compression spring 106 is mounted on the inner sleeve 92, being seated between the flange 96 thereof and the flange 104 upon insertion of the'cartridg e, "by the engagement of of the outer sleeve. "-The compression spring-{1 06, due to its inherent iorce, biases the inner sleeve -92 down wardlyrelative to the outersleeve 9'4. Thetwo sleeves are held in their spread apart position, as shown in Fig. 8, u'pon the "insertionof the refill cartridge 12 which only; frictiona'lly' engages the outer sleeve 94 by the engagement of a rim110 of footpiece 56 of 'tliecartridge with thejinwa'rdly directed -flange or. rim 100 of the outer slewi 3 Casing 16C having inner

Sleeve'92' is properly disposed relative to sleeve 94 flange 96 with the. shoulder 108 defined inthe outer sleeve between the two portions thereof. It will be under- 94 is rotated relative to the inner casing sleeve 92, the

cartridge footpiece 56, which is integral with the inner cartridge sleeve, as previously described, will be rotated relative to the outer cartridge sleeve, which is frictionally engaged with the inner casing sleeve, to project or withdraw the lipstick 14, as previously described.

In order to effect the ejection of the cartridge from the casing, the casing sleeves are telescoped by the opera- ;tor or user from the positions thereofv shown in Figs.

7 and 8. V

Such movement of the sleeves is limitedby the engageinvention and it is intended that such obvious changes and "modifications 'be embraced by the annexed claims.-

'Ha'ving thus described the invention, what is claimedas new and desired to be secured by Letters Patent, is:

-1. A casing for a refill housing of the typehaving an outer housing sleeve within which there is rotatably disposed an inner housing sleeve for projecting an article from and for withdrawing said article intosaid outer housing sleeve by relative'rotation of said sleeves, said casing comprising a pair of telescopically related tubular members, means to'limit the telescopic movement of said members in a first direction of increased telescopic relation, means to limit the telescopic movement of'said members in a second direction of decreased telescopic relation, the inner tubular member having means't'o' frictionally engage the outer housing sleeve and the outer tubular member having means to frictionally engage the innerhousing sleeve, whereby relative rotation of said tubular members effects relative rotation of the'housin'g means provided on the outer tubular member and a com- I means being the friction engaging means of said outer ment of the inner sleeve flange 96 with the outer sleeve rim 100,as shown in broken line in 'Fig. 8, and is facilitated by the expansion of the stressed spring .106. Such telescopic movement releases the frictional engagement of the footpiece rim 110 with the outer sleeve rim 100 so that the cartridge is no longer frictionally engaged with the outer sleeve 94. With the release of such fric-, tional engagement, the force of the stressed spring 106' is sufficient to move .theinner casing sleeve downwardly, as shown by the arrow 112, such movement being limited by the engagement of the innersleeve flange 96 with the rim 100 of the outer sleeve. Such downward movement of the inner sleeve results in the complete ejection or expulsion of the cartridge from the casing, as shown by arrow-.114. It will be noted from Fig. 7, that the inner sleeve flange 96 bears against an upper rim 116 provided on the footpiece 56 so thatrelease of the frictional engage- V ment 100110 applies the force of spring 106 through plementary portion of said inner tubular member movable between said spaced detent means, said friction engaging means comprising an inner surface friction portion on each of said tubular members, and one of said detent tubular member.
