'IClaimL (01.2.6-5.)

The present invention relates to containers for lip sticks and the like and in which the lip stick is adapted to be moved into and out of the container.

Containers of this character usually include y when the outer casing has been formed fromr casein or the like, in order to effect this above mentioned arrangement, it has been necessary to provide a sleeve which is xed to the inner surface of the outer casing and in which the spiral thread is formed. 'I'he provision of the spirally threaded sleeve has been necessary because it has not been possible to mold the spiral thread in the outer casing when it is made of casein or similar moldable material.

It is an object of the present invention to mold a pair of spiral tracks or guideways directly in the inner surface of a casing of casein or other similar moldable material and thereby eliminate the outer sleeve.

It is another object of the present invention to provide an improved container of this character which is shorter than containers made heretofore and, at the same time, will accommodate the standard size lip stick or other cosmetic. This produces a more compact container which may be more easily handled and which takes up less space in a pocketbook or the like.

Still another object of the present invention is to provide an improved device of this kind in which no rivets or like fastening means are required for holding the several parts in assembled relation and, hence, the parts of my improved container may be easily and quickly assembled.

A still further object of the present invention is to provide an improved device of this character in which the lip stick carrier has mounted thereon, for free laxial movement, a pin, the opposite sides of which engage in the respective tracks or guideways of the casing. 'I'his mounting of the pin in a free manner allows it to centralize itself and to accommodate itself to the guideways.

The present invention also aims to provide an improved device of this kind which is simple in construction and is economical to manufacture.

Other objects will be in part obvious, and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanving drawing, wherein is shown, for illustrative purposes, one of the embodiments which the present invention may take,

Fig. l is a longitudinal central sectional view of my improved container and showing the position of the several parts when the lip stick and carrier therefor are in fully retracted position;

Fig. 2 is a sectional view on the lline 2-2 of Fig- 1; and

Fig. 3 is a fragmentary longitudinal central sectional view of my improved container and showing the position of the several parts when the carrier is in partly projected position.

Referring more particularly to the drawing, Il designates a casing which may be of any desired shape and which is made of casein or some similar moldable material having substantially the same characteristics as casein. In the present illustrated disclosure, the casing I0 is shown as being of generally cylindrical form and open at each of its ends. The upper end of the casing is of reduced diameter and is provided with an external thread which is adapted to cooperate with a complementary thread provided on a cover I I. The inner surface of the casing I0 tapers upwardly and is provided with a pair of spirally arranged tracks or guideways l2 which extend through the lower edge of the casing l0 at diametrically opposite points. 'I'he guideways I2 extend in the same direction and terminate at points which are substantially in the same horizontal plane as the lower surface of the annular shoulder I3 formed on the interior of the casing and which overhangs the upper open ends of the guideways i2. Each guideway i2 comprises a pair of spirally arranged spaced apart parallel ribs I4 which may be molded integral with the casing at the same time at which the latter is molded and which project from the inner surface thereof. The formation of these spiral spaced apart ribs provides a spiral space or groove therebetween the bottom of which is formed by the inner surface of the casing l0. It will be noted that the spiral formation of the ribs I4 is a sharp one so that there is a considerable distance between the successive helices of the guideways I2.

Disposed within the casing III is a shell or tube I8 which may be of metal or `any other suitable material. The shell I6 is preferably cylindrical so as to conform to the shape of the casing l0 and may be drawn to the desired shape. II'he upper end of the shell is open and the edge thereof abuts the shoulder I3 to prevent upward movement of the shell within the casing. 'I'he lower end of the shell is closed by a bottom I1 provided with a polygonal shaped opening I8 which, in the present instance, is illustrated as being rectangular for a purpose later to be described. The shell is provided with a pair of diametrically disposed longitudinally extending slots I! which may be open through the upper end of the side wall of the shell, while the lower ends of the slots terminate in the lower edge of the side wall of the shell.

A generally cylindrical cup-shaped carrier 20 is provided for the lip stick 2|, and the carrier 20 has a slidingv t within the shell I6. The side wall of the carrier 20 is provided with a pair of diametrically opposed openings which receive a pin 22 in a freely slidable manner. The opposite end portions of the pin 22 extend through the respective openings in the carrier and the respective slots in the shell I6 and are slidably received by the respective guideways I2. The bottom of the carrier is provided with a circular opening 23.

The lower end of the casing I0 is of reduced diameter and is closed by means of a cap 2l rotatably mounted on the casing. The lower reduced portion of the casing is provided with an annular groove 25, and the cap has an annular groove 2B. These grooves are in registry when the cap is in place on the casing. A split resilient ring 26' is accommodated by the registeringgrooves and straddles the joint between the casing and cap' adjacent said grooves. The cap 24 is provided with a substantially centrally disposed boss 21 which is received by, and is of substantially the same size and shape as, the opening III in the bottom of the shell I6 so that the boss is snugly received by the opening whereby, when the cap 24 is rotated, the shell I6 will also be rotated. The circular opening 23 in the carrier accommodates the upper end of the boss 21 when the carrier is in the retracted position shown in Fig. l.

To assemble my improved container, assuming that. the lip stick is mounted upon the carrier and the pin is properly received by the openings in the carrier, the carrier may be positioned within the shell I6 by sliding the carrier into the open end of the shell and with the opposite ends of the pin engaged in the respective slots of the shell. 'I'he shell I6 and carrier 20 may then be introduced into the'casing I0 through the lower open e'nd thereof until the upper edge of the wall of the shell engages the shoulder I3 of the casing. As the shell is being moved upwardly into the casing, the opposite ends of the pin 22 may be engaged in the respective guideways I2. The ring 26 may now be inserted in the groove 25 which has a depth substantially equal to the thickness of the ring. The cap .24 may now be slid into proper position over the lower end of the casing, at which time the grooves 25 and 26 will register and the' ring 26 will spring into the groove 26. Since this groove 26 has a depth less than the width of the ring, the latter will assume a position in which it is in line with the joint between the casing and cap, thereby permanently locking the cap and casing together, but

permitting rotation of the cap on the casing. The polygonal shaped boss 21 and opening Il in the shell I6 eect a driving-connection between the cap and shell so that rotation of the cap also rotates the shell which, in turn, rotates the pin 22 and thereby causing the pin and carrier to travel upwardly in the casing by virtue of the spiral guideways I2. Since the shoulder I3 abuts the upper edge of the shell I6 and overhangs the guideways I2, it will engage the opposite ends of the pin 22 to limit the upward movement of the pin and carrier to prevent the pin from escaping from the guideways. The pin 22, due to its loose mounting, may centralize itself and accommodate itself to the taper of the casing and any irregularities in the guideways. It is also noted that the shell is held in the casing by having contact at only two points, namely, the shoulder I3 and cap 24, being free of connection with the casing between these points.

It is also apparent that, since there are no rivets or other similar fastening devices employed, the several parts of my container may be quickly and readily assembled without the use of tools or the like and the container may be made relatively short. It is also obvious that, by providing guideways having relatively large helics and upstanding ribs, the guideways may be molded directly in the casein casing thus eliminating the outermost sleeve heretofore considered necessary when a casing of casein or other similar moldable material was employed.

It will be observed that in my improved arrangement the casing has a pair of spiral grooves,

and the pin associated with the carrier has its opposite ends respectively engaging in the grooves, an arrangement which gives a very well balanced movement and permits of a carrier of reduced height. Since the carrier is supported at opposite sides by the pin, there is no tendency to cant the carrier when it is moved up and down within the shell and, therefore, the pin may be located adjacent the lower end of the carrier and the carrier -may bevmade relatively shorter.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a hunting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
