14 Claims.

This invention relates to holders for'such articles as lipsticks. More particularly, the invention deals with devices of this kind constructed of-a minimum number of parts wherein the holder proper or cartridge is arranged in its entirety within a casing and includes a threaded or helix portion, by means of which indentures or projections formed from the material of the casing will operate in the helix in providing rotary and longitudinal movement of the cartridge of the device with respect to the casing in projecting the lipstick and inlydrawing the lipstick into the casing. Still more particularly, the invention deals with devices of this kind wherein the casing includes a relatively wide opening in its side wall sufficient to expose a roughened surface of the helix thereto to be accessible by a digit of a hand while grasping the device at one end portion thereof. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and in which the separate parts are designated by suitable reference characters in each of the views and in which:

The structure shown and' described in this ap.. plication constitutes an improvement over my Patent No. 2,412,999; granted December 24, 1946,

and distinguishes from said patent primarily in providing on the surface of the cartridge of the holder a thread, spiral or helix having a knurled or other roughened surface to provide a frictional or gripper surface thereon to facilitate the manual operation in effecting rotary movement of the cartridge and further. in providing thread, spiral or helix engaging means on the casing of the holder and formed integral therewith to feed the cartridge longitudinally of the casing of the holder in the rotation of the cartridge by a digit of a hand.

In Figs. 1 to 4 inclusive, I have shown at I2, the outer casing or jacket of a holder which includes an enlarged head or closure I3 at one end, providing on the periphery of the casing a4 shoulder Ill against which the lower end of a thimble shaped cap or cover I5 is adapted to rest. The cover I5 is shown in extended position in Fig. 1, preparatory for attachment to the holder when the lipstick I6 is withdrawn into the casing or shell I2.

The lipstick I6 is arranged in a holder or cartridge I'l comprising an elongated body divided by a central partition wall I8 into recesses I9 and 20 forming tubular end portions of said cartridge. The partition I8 includesa raised conical mem- -ber 2| extending into the recess I9 and apertured centrally, as seen at 22, so that in pressure feeding the lipstick I5 into the Arecess I9, the lower end of the lipstick will be spread over the conlcal member and forced into rm engagement with the walls of the recess I9 to securely retain the lipstick against displacement therefrom. The aperture 22 provides a vent for the discharge of air as the snugly fitting lipstick is forced downwardly in the recess I9.

On the periphery of the cartridge I'I is formed a spiral, thread or helix 23the outer surface of which is knurled or otherwise roughened. This thread or helix terminates at one end to form a circumferential shoulder 24 which is adapted to abut in an inturned rim or flange portion 25 bordering the opening 26 at the discharge end of the casing I2. The opening 26 is sufliciently larger than the diameter of the lipstick I6, so as to provide a free passage of the lipstick therethrough without danger of scraping the surfaces thereof. In assemblage, the cartridge with the lipstick therein is inserted into the casing before the flange 25 is turned inwardly. After the assemblage has been made, this flange is then turned inwardlyto retain the cartridge I'I against displacement. The outside diameter of the thread or helix p ortion of the cartridge is made to fit snugly but yet freely in the bore of the casing l2 to be free to rotate therein and move longitudinally thereof.

f The casing I2 has a substantially elliptical aperture 21 formed in one wall thereof substantially centrally with respect t the ends of the casing, and is suiiiciently wide to expose the helix 23 therethrough to be engaged by a digit of a hand, as will clearly appear from a consideration of Fig. 3 of the drawing, and as will also be apparent from a consideration of Figs. 1 and 4. At the sides of the opening 21 are arranged thread or helix engaging members 28 which are in the form of lugs, and these lugs are normally within the contour of the cylindrical Walls of the casing I2. Prior to assemblage the lugs 28 are turned inwardly, as clearly seen in Fig. 4. In placing the cartridge I1 in the casing, the lugs 28 engage in the recesses between the thread or helix 23, and it will thus. be seen that upon rotation of the cartridge, the latter will be elevated or retracted relatively to the casing. The lugs 28 are turned inwardly, as clearly seen in Fig. 4 to engage in the recesses between the thread or helix 23. In this connection, it will be apparent that the aperture 21 is disposed in an angular relationship so that 'the members or lugs 28 will be so spaced one with respect to the other as to correspond to the pitch of the thread or helix 23. When the cartridge is fully retracted, as seen in Fig. 2 of the drawing, the lipstick will be substantially retained within the upper end of the casing I2. A new lipstick may protrude slightly therefrom, as seen in Fig. 2, in which event, the cover I is made sufliciently longer and with a domed top 29 to clear the protruding rounded end 30.

In Figs. 5 and 6 of the drawing is shown another adaptation of the invention wherein a casing 3| is employed which differs from the casing I2 in several respects. First this casing has an open slightly enlarged end 32 having spaced circumferential beads 32a. A cap 33 is adapted to be inserted into the end 32 and the sleeve portion of this cap includes opposed nibs 34 which are adapted to be snapped into the lowermost bead 32a of the enlarged end 32. This type of construction is adaptable to devices of the kind shown in Figs. 1 to 4 inclusive, and at the same time, the closed end as at I3, is also adaptable to the structure of Figs. 5 and 6 as well as the other figures.

The casing 3l further diiers from the casing I2 in providing an opening 35 which can be narrower than the opening 21 and is preferably longer than the opening 21, and instead of having the lugs 28 therein, a cartridge 36 or the helix 31 thereof has a threaded engagement with three series of vertically spaced nubs or elongated indentations 38. The series in the construction shown comprising three nubs arranged in longitudinal alinement on the casing 3l and three series of these are spaced circumferentially to register with the pitch of the helix 31 in the cartridge. This construction provides substantially the equivalent of a continuous thread in the casing 3|, but at the same time, minimizes the frictional engagement by reducing the surface contact between the casing and the helix of the cartridge. Aside from the arrangement of the helix on the cartridge 36, this cartridge otherwise will be of the same general structure internally as the cartridge I1. In this connection, the same will be true 0f the cartridges shown in Figs. 7 to 10 inclusive.

The casing 3l includes an inturned flange or rim39, similar to the rim 25. However, by employing a detachable cap 33, the rim 39 may be preformed and the cartridge inserted into the casing 3| through the lower open end thereof. This type of construction permits renewal of the cartridge. However, it must be apparent that with the several devices shown, new lipstick inserts may be inserted into any of the cartridges, in that it will be relatively simple to clean out the recess in the cartridge for the reception of the new lipstick. At this time, it is also well to bear in mind that the cartridge may be constructed of plastic material and th'us economically produced as a casting. This may be fitted in a metallic casing, but on the other hand, in some instances, the casing itself and cap I5 may all be composed of plastic materials. The turned in flange 25 may be formed by heating the end of the casing to facilitate the inward flanging thereof.

In Figs. '1 and 8 of the drawing is shown a slight modification of the structure shown in Figs. l to 4, and 5 and 6, combining certain general features of both forms of constructions shown in these figures. In other words, in Fig. 8, the casing 40 of the general contour of the casing 3l is employed including the lower enlarged beaded portion 4I .and detachable cap 42 and an upper inturned flange 43 at the discharge open end of the casing. The wall of the casing 40 instead of having an elongated aperture, like the aperture 35, is provided with an angularly arranged and substantially elliptical aperture 44, bordered at upper and lower edges in

inturned lips

45 and 46, which are adapted to enter the recess above and below the spiral, thread or helix 41 of a holder or cartridge 48. These lips will serve to engage the helix in the manner clearly illustrated in Fig. 8 to feed the helix longitudinally of the casing 40 as the helix is rotated by the digit of a hand engaging the knurled or roughened surfaces provided on the helix as in the other forms of construction shown. In the several forms of construction which I employ, the apertures or openings are all arranged substantially centrally of the casing of the holder, so as to provide a grip of the casing below the opening with the casing arranged in the hand, in such manner that the thumb of the hand can be moved across the opening engaging knurled portion of the helix vin rotating the cartridge to positively feed the same upwardly and downwardly in the casing, thereby providing a one hand operation and use of the lipstick, in contrast to most devices of this kind which require the use of two hands in the adjustment or feed of the lipstick in the holder.

In Figs. 9 and 10 of the drawing is shown a slight modification of the structure illustrated in Figs. 5 and 6, the sole difference being in substituting for the three circumferentially spaced series of three longitudinally alined nubs, three elongated nubs or indentations 49 arranged longitudinally at an angle common to the pitch of the helix 50 on the cartridge 5I, these elongated nubs or indentations being in the form of a portion o-f a thread of the character of a buttress thread. It will appear from a consideration of Fig. 9 of the drawing that the upper walls 52 of the members 49 are relatively sharp to produce sharp angular engagements with the lower edges of the coils of the helix. This construction will provide a positive feed of the cartridge longitudinally of the casing 53 in both directions. This is also true of the construction shown in the other figures, thus longitudinal play of the i cartridge is minimized in all forms of construction shown.

By virtue of the arrangement of the various lugs, nubs or other projecting thread or helix engaging members, the same may be preformed on the casing in that the cartridgeis adapted for threaded engagement therewith for `insertion into the casing regardless of which end of the casing is employed for insertion of-v the cartridge.

From the foregoing, it will be apparent that a minimum number of parts are employed in the construction of the holder, and furthermore the parts can be simply and economically formed of metal or plastic materials,A or a combination of such materials. Further ore, it will be apparent that the over-al1 size of the resulting holder is minimized, and in this respect, it must be kept in mind that sizes of parts in theiaccompanying drawing are exaggerated slightly for clarity of illustration, and do not necessarily represent the actual sizes employed in the finished product. It will also be apparent that with the forms of construction shown in Figs.` 5 to 10 inclusive, employing the enlarged head or the equivalent thereof, a stop shoulder is formed similar to the shoulder i 4 to limit movement of the cap, a cap being employed on all holders, and when applied, the resulting unit will represent a cylinder having a common diameter throughout the length thereuf.

By providing a lipstick supporting cartridge which in its entirety is disposed within the bore of the casing, it will be apparent that when the usual cap, such as the cap I5 of Fig, 1 is supported on the casing, any relative rotary move ment between the casing and cap will not transmit movement .to the cartridge. This has been an objection to many devices of this kind where the cap has operatively engaged the cartridge or its equivalent and relative rotary movement as mentioned above would contribute longitudinal movement tothe cartridge, which would operate to jam the lipstick materialiin the closed end of the cover. With the present constructions disclosed,

, it is essential to remove the cap to expose the opening in the casing in order to operate the cartridge in either direction in the casing.
