Pateied Dee. 23, 1947 ROTARY LIPSTICK HOLDER Alexander S. Mackey, Ottawa, Ontario, Canada, assigner to Scovill Manufacturing Company, Waterbury, Conn., a' corporation of Connecticut Application March 12, 1946, Serial No. 653,860

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 vformed 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 in drawing 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 suilicient 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. Thel 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:

7 Claims. s (Cl. 20G- 56) The structure shown and described in this application constitutes a continuation-impart of the structure shown and described in my prior application Ser. No. 569,664, filed December 22, 1944. The present application includes a slight modification of the structure shown, more particularly in Fig. 11.

In Figs. 1 to 4 inclusiveI I have shown at I2, the

Vouter casing or jacket oi a, holder which includes cap or cover I5 is adapted to rest. yThe cover I5 ill is shown in extended position in Fig. 1, preparatory for attachment tothe holder when the lipstick IB is withdrawn into the casing or shell I2.

The lipstick I6 is arranged in aholder or cartridge Il 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 includes a raised conical member 2| extending into the recess I9 and apertured centrally, as seen at 22, so that in pressure feeding the lipstick I5 into the recess I9, the lower end of the lipstick will 'be spread over the conical 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 oi air as the snugly fitting lipstick is forced downwardly-in the recess I9.

On the periphery of the cartridge il is formed a spiral, thread or helix 23, the outer surface of which is knurled or otherwise roughened. This thread or helix terminates at one end to form a circumferential shoulder 2li which is adapted to abut in an inturned rim or flange portion 25 bordering the opening 2B at the discharge end of the casing I2. The opening 26 is suiiciently 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. vIn 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 inwardly .to retain the cartridge I1 against displacement. The outside diameter of the thread or helix portion of the cartridge is made to t snugly but yet freely in the bore of the casing I2 to be free to rotate therein and move longitudinal--` ly thereof.

'I 'he casing I2 has a substantially elliptical aperture 21 formed in onev wall thereof vsubstantlally centrally with respect to the ends of the casing, and is sufciently 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 f orm of lugs. and these lugs are normally within the contour of the cylindrical walls o f 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 orretracted 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 aper- This type of construction permits renewal of the cartridge. However, it must be apparent that ture 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 fullyretracted, 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 I5 is made suiciently 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 diiers from the casing I2 in several respects. First this casing has an open slightly enlarged end 32 having spaced circumferentia1 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. 'Ihis 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 3I further differs 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 of the cartridges shown in Figs. 7 to 10 inclusive. y

` The casing 3| includes an inturned flange or rim 39, 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.

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 thus 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 heatingthe end of the casing to facilitate the inward flanging thereof.

In Figs. 7 and 8 of the drawing is shown a slight modification of the structure shown in Figs. 1 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 ange 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 48 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 substan? y 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 of 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 0f the members 48 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 inl both directions. This is also true of the construction shown in the other figures, thus longitudinal play of the cartridge is minimized in all forms of construction shown.

In Fig. 11, I have shown a slight modification which incorporates the spacing features of some using elongated nubbins or lugs Vof the typeV disclosed in Figs. 9 and 10. In Fig. l1, 54 represents the outer casing of the device, which maybe generally similar to the casings I2, 3|, 40 and 53.

The casing'5l has a large rectangular opening 55 at the lower portion thereof, and the walls of the casing have three longitudinally and circumferentially spaced and slightly elongated yinwardly pressed lugs or nubs, as at l56, 51 and 58, these nubs being arranged at an inclined plane and in a spiral relationship onewith respect to the other to match a spiral groove 59 in a holder or cartridge 60, similar to the cartridge 5| or the carv` tridge 36 and 48, the only difference being that the spiral groove 59 is narrower and disposed in an opposite direction so as to require rotation in a right to left direction by the thumb of a hand in feeding a lipstick outwardly rather than in the left to right direction, as disclosed in fthe other figures. The cartridge 60 has between the spiral groove 59 the roughened or` grip surfaces 6I,

which facilitates rotation of the cartridge, andl similar to theroughened or grip surfaces shown in Figs. 5, 8 and 9.

Considering Fig. 11 of the drawing', it will appear that the uppermost nub 56 is disposed above the aperture 55, the nub 51 is disposed at one side of the aperture 55, whereas the nub 58 is disposed` below the aperture 55 and the three nub's are spaced circumferentially and positioned in the spiral path defined by the spiral groove 59 so as The structure of Fig. 1`1 is only shown in party -to illustrate the modification employed, but the casing of Fig. 11 as well as the holder, aside from the modied structures disclosed, will be the same as that shown in the other figures. Here particular reference is had to the means checking movement of the cartridge or helix in its movement in both directions in the casing, as Well as the means for supporting the lipstick in the cartridge, as more specifically disclosed in Fig. 3 of the drawing.

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 cartridge is adapted for 'threaded engagiement therewith for insertion into the casing regardless of which end. of the casing is employed for insertion of the cartridge. From the foregoing, it will be apparent that a ploying the Venlarged head or the equivalent thereof, a stop shoulder is formed similar to the shoulder I4 to limit lmovementof the cap, a cap being employed on all holders, and when applied,y

the resulting, unit will represent a cylinder having a common diameter through Athe length there- 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 Yrotary movement 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 to the cartridge, which would operate to jam the lipstick material in 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.
