Fig. 16 is a section on the line 16-16 of Fig. l;

Fig. 17 isa vertical medial longitudinal section of a mold for the sleeve, according to Figs. 6 and 7, showing a step inthe process of forming the sleeve; .and

Fig. 18 is a section on the line 18-18 of Fig. l7.

Referring to the drawings, the holder comprises a base 1 the body portion of which is tubular and has the atteued but somewhat rounded vertical side walls 3 so that the body portion is approximately square in transverse cross-section. At their upper ends the side walls are integrally provided with an inwardly extending continuous annular flange 5 having a circular cylindrical opening 7 coaxial with the longitudinal axis of the base. At its lower end the base is formed with an outwardly projecting flange 9 extending continuously around it, which ange forms at its upper side a shoulder 11 at the exterior of the walls 3. At its under side the flange 9 is recessed, as indicated at 13, to form an annular shoulder 15 possitioned inwardly from the bottom of the base, as clearly indicated in Fig. 14.

Received in the recess 13 of the base 1 of the holder is a closure 17 provided with an upstanding peripheral ange 19 (Fig. l5) which lits the side walls of the recess and is cemented thereto after the interior parts of the holder are assembled with the base. Extending upward from the body of the closure is a circular ange 21 the outer cylindrical surface 23 of which forms a bearing surface coaxial with the base when the closure is assembled with it.

Received by the base 1 of the holder is a lower portion 25 of an elongated sleeve 27 of circular cross-section 2,704,598 Patented Mar. 22, 1955 the inner bore 29 of which is shown as of uniform diameter throughout the length of the sleeve. The upper portion 31 of the sleeve, as shown, is exteriorly of reduced diameter so as to form an annular exterior shoulder 33 (Figs. 6 and 7) on the sleeve. In the assembled device the sleeve at its lower end iits over the circular ange 21 of the base and interiorly thereof is rotatably mounted on the cylindrical bearing surface 23 provided by that flange. The lower end of the upper portion 31 of the sleeve has a bearing on the cylindrical surface 7 of the flange 5 of the base 1. The shoulder 33 on the sleeve coacts with the under side of the ange 5 to prevent substantial outward movement of the sleeve relative to the base, while the lower end of the sleeve coacts with the upper surface of the closure 17 to prevent substantial motion of the sleeve longitudinally thereof relative to the base in the opposite direction. As shown, the sleeve is formed with a screw slot 35 having the opposite beveled side walls 37, which slot will hereinafter be more fully described.

Received in the sleeve 27 is a cup-shaped member 39 having the lateral walls 41 and bottom wall 43. In- Iteriorly of the cup-shaped member its lateral walls and bottom are integrally formed with angularly spaced narrow radially projecting ribs 45 extending upwardly from said bottom for part of the height of said member. These ribs are adapted to cut into the end of a cosmetic stick inserted in the cup for removably securing it thereto. The lateral walls 41 of the cup are of slightly less diameter than the bore of the sleeve 27 which receives it, these walls being exteriorly formed with the spaced longitudinally extending ribs 47 extending for part of the longitudinal length of the cup, the ribs being adapted to bear on the surface of the bore of the sleeve for guiding the cup, it being found that in this way binding of the parts when made of molded plastic material is effectively prevented.

As shown, the bottom of the cup-shaped member 39 is integrally formed with a downwardly projecting flattened stem 49 which at its lower end integrally carries a thin circular disc-like part 51 adapted peripherally to bear on the walls of the bore of the sleeve 27. The disc-like part 51, being materially spaced from the ribs 47 on the cup-shaped member 39, effectively acts in conjunction with those ribs to prevent tilting of the cupshaped member relative to the bore of the sleeve 27 so as to prevent binding of the parts. Also, as shown, the disc-like part 51 and adjacent end of the stem 49 are integrally formed with a projection 53 extending radially of the disc. This projection has an inner portion 55 which is of attened rounded shape in cross-section as indicated in Fig. 13, and an outer portion 57 of reduced width which is circular in cross-section as indicated in Fig. 12. The base 1 of the holder is interiorly formed at one of its corner portions with a pair of spaced ribs 59 extending substantially the length of the base. When the part comprising the cup-shaped member 39 and disc 51 is inserted in the sleeve 27 the projection 53 will extend through the screw slot 35 into the space between the two ribs 59, the sides 61 of the inner portion 55 of the projection coating with those edges 63 of the screw slot which are formed by the intersection of the side Walls 37 of the slot with the bore of the sleeve, while the outer portion 57 of the projection cooperates with the adjacent walls of the ribs 59 to prevent rotation of the part comprising the cup-shaped member and disc 51 relative to the base so that when the sleeve is rotated relative to the base the screw slot 35 will cause that part to move longitudinally of the sleeve, the direction of movement of the part depending upon the direction of rotation of the sleeve. In this way the cosmetic stick carried by the cup-shaped member 39 may be caused to project more or less from the upper end of the sleeve.

As shown (see Fig. 6), the screw slot 35 intersects the lower edge 65 of the sleeve 27, the upper edge surface of the screw slot having a downturned portion 67 which intersects the edge 65 of the sleeve substantially at the same point where the lower edge surface of the screw slot intersects it, in this way substantially to close the lower end of the screw slot to retain the projection 53 within the slot after it is inserted. The sleeve, being made of plastic material, is somewhat resilient, which permits the portion 69 of the sleeve lying between the lower edge surface' of the screw slot and the lower edge of the sleeve to be bent away from the downturned portion 67 of the upper edge surface of the screw slot to permit the projection 53 to be entered into the screw slot when inserting the part comprising the cup-shaped member 39 into the sleeve. After the projection is entered into the screw slot the resiliency of the sleeve will cause the portion 69 thereof to move into cooperation with the downtumed portion 67 to retain the projection within the slot.

As shown, the holder is provided with a can 71 which is in the form of a tube of the same cross-sectional shape as the base 1 and has a closed end 73 and an open end which tits over the base to cause the lower end edge of the cap to bear against the shoulder 11 on the base. Interiorly the cap is shown as integrally formed with angularly spaced ribs 75 adapted frictionallv to bear against the outer surface of the sleeve 27. The sleeve, being of plastic material, is somewhat resilient, this resillency causing a snug tit of the ribs with the sleeve securely to hold the cap on the holder when the ribs are forced over the sleeve. l

To mold the sleeve 27 having the screw slot 35 there may be employed a mold 77 having the two mold halves 79 and a core 81. one of the mold halves being provided with a passage 83 for use in injecting the plastic material under pressure into the mold cavity. To mold the screw slot the mold halves are shown as provided with the internal ribs 85. Because in separating the mold halves they must move vertically relative to each other it is not possible, when the screw slot has any considerable pitch, to have the ribs throughout their entire length follow a true helix such as is indicated by the line 87 (Fig. 8) because obviously in such case the ribs would bind in the screw slot adiacent the parting surface 89 of the mold when it was attempted to separate the mold halves. To avoid this diiculty the ribs are so shaped that adjacent the mold parting surface the screw slot molded by them has. at its inner edges 63. short portions 91 (Fig. 8) at each of opposite sides of the parting surface that are normal to the parting surface, the remaining portions of the inner edges 63 being helical. Further, to prevent binding of the ribs in the screw slot when the mold halves are being separated, the ribs are so shaped as to form wide beveled surfaces 93 (Fig. 8l on the side walls of the screw slot at those portions 91 of the inner edges of the screw slot which are convex by reason of the lportions 9l-thereof.

lt will be understood that within the scope of the appended claims wide deviations may be made from the form of the invention described without departing from the -spirit of the invention.
