Sept- 2, 1952 c. H. BRAsl-:L-TON CARTRIDGE-TYPE LIPSTICK Filed Sept. l5, 1948 4 ill Patented Sept. 2, 1952 UNITED STATES PATENT oFFlcE Chester H. Braselton, New York, N. Y. Application September 15, 1918,` Serial No. 49,327

Thisinvention relates to lipsticks and other pomade or solid perfume applicators, and more particularly to those of the detachable type, such as shown in my co-pending application, Serial No. 699,026, led September 24, 1946, now Patent No. 2,565,346, dated August 21, 1951, and relates more particularly to a design and construction for reducing the cost of manufacture of the types of cartridge applicators shown in my co-pending application above referred to.

This invention relates more particularly to improved means for establishing a driving relationship between the feeding mechanism of the cartridge and the casing or base adapted to receive the detachable cartridge when said cartridge is in place vin the casing or base. It relates, generally, to means for establishing a frictional driving relationship for the feeding mechanism of the cartridge when the same is in place for use in the casing or base such that rotation of the wall of the cartridge with respect to the base when the cartridge is in place, will cause feeding of the pomade or lipstick material towards the applying end of thejcartridge. By establishing this frictional driving connection as shown herein, it is not necessary to have the cartridge in any certain radial relationship when it is forcedinto position in the base, the establishment of the driving relationship Abeing accomplished whenever the cartridge is pushed into position into the hollow casing of the base.

Another feature of this invention is the construction wherein the wall of the cartridge, preferably made ,of metal of tubular formation, is forced inwardly by swaging or rolling to form an 5 claims. (c1. zoe-'56) integrally projecting spline in the wall of the tube from which the cartridge is made. This'spline or longitudinal indentation does not extend the Whole length to the extreme ends of the cartridge tube. but leaves a portion at one end circular at the inside diameter. wherein may be mounted for rotative, but non-longitudinal movement with respect thereto, a closure for closing that end of the cartridge and serving to rigidly support a feeding screw axially in the cartridge. The fastening of the circular end of the cartridge with the closure mounted, partially therein is accom-V plished by having a peripheral groove located in v the periphery of a smaller diameter of the' closure which is adapted to fit within'the circular end of the cartridge. 'The' cartridgel is placed "over Y I 2 Y tudinal screw and has a groove or'notch in its periphery adapted to engage the inwardly pro- Jecting spline of the cartridge to establish nonrotative connection between the plunger and the spline of the cartridge. The closure for the end of the cartridge has another diameter greater than the inside diameter 0f the cartridge, below where the cartridge engages the closure, and this enlarged diameter of the closure is sufliciently large to fit loosely in the inside diameter of a hollow casing which forms, or is connected, with the base of the casing. The enlarged diameter of the closure has a peripheral groove adapted to receive a frictional driving means, the tension of which holds it in place in the groove but which extends slightly beyond the periphery of the larger diameter of the closure so as to establish a irictional driving connection with the inside Wall of the .hollow casing when the .cartridge is assembled.

Y

In the drawings, I represents a shouldered enlargement of the hollow casing adapted to detachably receive a lipstick or pomade-containing cartridge 2.` 3 represents the cap or closure adapted to cover .the cartridge in the upper end of the hollow casing when in place thereon, and serveas a protective cover. The shouldered portion' I of the hollowcasing 4 serves as an abutment for the cap and also as a grip for holding the hollow casing. This casing 4 has an external abutment 5 to limit the downward movement of the capi when placedthereon, said cap being held onthe casing by frctional engagement with the periphery of the hollow casing. The casing 4 is further reduced in diameter at 1 to relieve this area against scratching when the cap is put on or taken off. Casing 4 is hollow on the inside, having an inside diameter -8 slightly bevelled at 9 at its open end on the inside. The hollow casing is closed by a closure I at its bottom end, either integral with or attached thereto.

The cartridge 2 of my invention is constructed from a tube of circular inside diameter with the exception that at one portion of the periphery, preferably on the longer side, the walls of the tube is forced in by rolling or swaging so as to form an inwardly projecting, relatively unnoticeable spline II, this extending from point I2, near one end, to the point l other end, but not extending throughout the whole length 0f the cartridge tube. The purpose of this spline is to establish non-rotative connection between the cartridge 2 and plunger I4, which has a notch I5 adapted toiitover spline so that the plunger I4 may move longitudinally with respect to the cartridge 2, but not be rotated with respect thereto.

One end of the cartridge 2 is closed by closure I6, having a portion II of a diameter such as to fit the inside circular wall of that end of the cartridge tube. The closure I6 has another portion I8 of larger diameter adapted to movably fit the inside diameter of the hollow casing. This portion of larger diameter and the portion of small diameter adapted to t inside of the cartridge tube, are separated by a peripheral groove |60, in the closure, the' smallest diameter of which is less than the outside diameter I7, and provides spaced into which the lower end of the cartridge 2 may be spun into to form a rotative, but nonlongitudinally movable relationship between the cartridge 2 and the closure I6. The closure IS has a screw I9 rigidly fastened thereto, either by peaning, force-fitting, soldering, or otherwise, which closure supports this screw axially of the cartridge 2.l The plunger I4, above referred to, has a centralopening threaded to fit the screw I9 so that .these two elements are threadedly connected. Rotation of the closure I6, with respect to the cartridge 2, will cause the plunger I4 to move only longitudinally of the cartridge 2, being prevented from rotation with respect thereto by the spline II working in notchIS. In this way the lipstick or other pomade material which fills the space between the plunger I4 and the applying end of the cartridge is fed towards the applying lend when the closure I6 is rotated in one direction with respect to the cartridge 2. In this way lipstick or other pomade material may be kept supplied to the applying end of the cartridge by rotating the closure I6 with respect to the cartridge 2.

In order to establish a relationship whereby the cartridge is held in place in the hollow casing 4, and whereby the closure I6 may be caused to be rotated with respect to the cartridge 2 when the hollow casing 4 is rotated with respect tothe cartridge 2, I provide on the portion I8 of the closure IS of a diameter larger than the diameter ,'I'I, aV peripheral groove 20 therein, in which is mounted a spring 2l of suchtension and diameter v.to be held in the Agroove 20 by its tension,`yet portions thereof allowed to -yield inward-lywhen the closure and cartridge are pushed intothe Vopencnd of the hollow casing 4. The springfZI doesfnot project sulciently beyond the large-diameter I8 of the closure, but that the projectingfportions thereof will always be-wedged I3 near the` inwardly by the open end of the hollow casing when the cartridge is forced into place. To make sure of this inward wedging of the spring, I, in some cases, provide a slightly internal bevel 9 in the open end of the hollow casing which further tends to wedge the spring inwardly at the beginning of the insertion of the cartridge in place. The diameter of the spring 2I, when in its peripheral groove '20, and the depth of the groove therein, is such that less than half of the diameter of portions of the spring is all that projects beyond the internal diameter of the hollow casing 4, the spring stock being of sufficient diameter and strength as to yield inwardly as the spring is wedged inwardly due to insertion of the cartridge vin the hollow casing. I prefer vthat the spring, when in place and acting freely, does not project at any point more than half of the cross sectional diameter of the stock from which it is formed, beyond the extreme periphery I8 of the closure, and better operation is found whenthe vclearances are such that 'the' spring does not project even this much beyond the large diameter I8 of the closure. The spring preferably yields just enough to allow the insertion of the cartridge readily, it being of sufficient strength as to establish a firm, yielding, driving relationship between the closure I8 and the inside of the hollow casing, the spring serving, by this frictional connection, to not only retard or prevent rotation of the closure'with respect to the hollow casing, but also to hold the cartridge in place longitudinally during the use of the device, yet still permitting ready removal of the cartridge by pulling the same longitudinally whenever it is desired to disconnect the same from the hollow casing. Thespring ring 2I need not be, and 4invdeed preferably is not, made with great care to obtainexact circularity or flatness, as it is its departure from true circularity or atness that insures its obtaining a driving grip on the closureIG for the cartridge sleeve 2, as well as the wall 4 Aof, the base I, when the cartridge is entered into the base in any position of relative rotation of the two, as shown in Fig. 2.

In Fig. 6 rl2 have shown, by enlarged view, the action of the wedging surface 9 on the hollow casing aiding to wedge portions of the, circular spring ZI inwardly at the moment of beginning of insertion of the cartridge in the hollow casing. While this is not always necessary it is useful in helping to prevent Vany jamming of the spring between the large diameter portion I8. of the closure lI Eand the inside ofthe hollow casing 4 in casetoo 'loose a t should otherwise exist between .this closure and the hollow' casing. When these parts are Vmade with Athe proper tolerances and dimensions, however, the internal bevel of `the open end of the hollow casing may be eliminated, if desired.. although in certain rela-A tionships vof the cross-sections this bevelling of the interior ofthe hollow casing 'may be an advantage.

I have shown an irregular shaped open end of the applicator 2, such as shown in my allowed application, Serial No. 699,025, filed September 24, V1946. as I find this a very beneficial shape for the endoftheV applicator for lipsticks, and highly desirable, vto valways provide a ridge of free lipstick zvnaterialacross the diameter of the-cartridgef- This, of course, is not necessary for other forms of pomade or solid perfumes, in which case I generally have the applicator end of the cartridge shaped straight'across. For someother forms of; applicators forthe cartridges, the cartridges, however, may have to be shaped for the particular uses desired.
