Milton Oliver Flower, Coviua, Califi, assignors to Max Factor 82 Co., Hollywood, Calif, a corporation of Delaware Filed Aug. 14, 1963, Ser. No. 302,070 2 Claims. (Cl. 206-56) This invention relates generally to lipstick holders and more particularly to a holder having a refill capability wherein a locking member is provided to assure positive engagement between drive portions of the holder and the refill.

In accordance with the present invention, a lipstick holder has been devised wherein a ball-in-socket connection is effected between the pomade receptacle and the cup carrier which comprises a portion of the drive mechanism. In effecting the refill, a new pomade and receptacle are urged longitudinally with respect to the holder proper until the ball is received within a cavity within the base of the receptacle. Thereafter, the drive mechanism of the holder may be operated to retract the pomade into the holder.

The lipstick refill is engaged within its plastic container and during the aforementioned retraction it is necessary to withdraw the pomade from its container and to overcome the frictional forces between the pomade and the interior of the refill container.

It is a primary feature of the present invention to provide a locking member within the base of the refill which will secure the pomade cup and holder drive mechanism in locking engagement prior to withdrawal of the pomade from its refill container. The provision of the locking member greatly enhances foolproof operation of the refill sequence and in effect makes impossible the disengagement of the respective parts which may otherwise occur due to the internal frictional forces attendant upon withdrawal of the lipstick pomade from the refill container.

In the following description reference is made, by way of a non-limiting example, to one form of construction of a combination holder and locking device devised in accordance with the invention and illustrated in the accompanying drawing in which:

FIG. 1 is a view showing the relative holder and refill in position before their mutual engagement;

FIG. 2 shows the holder and refill after engagement;

FIG. 3 is a cross section taken in the direction of arrows 33 of FIG. 2;

FIG. 4 is a detail showing the side elevation of portions of the refill, including exterior portions of the locking member; and

FIG. 5 is a detail perspective showing of the locking member.

Referring now to the drawing, reference numeral indicates generally the upper applicator tip portion of a lipstick holder. The holder 10 includes an upper casing 11 which includes an inclined applicator tip 110 and a collar 11b. A lower casing 12 is disposed below the collar 11b for free rotation with respect thereto as will be seen. A low pitched helically threaded sleeve 13 is frictionally secured to the casing 12.

Coaxially within the

members

12, 13, is a hollow inner body 14 which is secured within the collar 11b for common rotation therewith. Within the body 14 is a carrier 16 having teeth 16a at opposite sides thereof which extend through diametrically opposed longitudinal slots in the body 14. The teeth 16a are engaged within the helices of the sleeve 13 such that relative rotation of the mem- 3,217,869 Patented Nov. 16, 1965 17a and an upper larger cavity 20 wherein the ball may expand to prevent disengagement from the receptacle 18. Preferably the carrier 16a, ball 17 and the lipstick receptacle are made of deformable plastic such as nylon to permit the ball 17 to be deformed as it is forced through the restricted passage 19, thereafter assuming its normal expanded shape within the cavity 20. Also, the ball will be provided with a slot 17b which will assist its deformation, which slot cooperates with the locking member of the invention as will be described.

The cup 18 contains the base of a lipstick pomade 21 and advantageously, the cup and pomade are packaged for refill purposes within a plastic outer sheath or container 22. The container 22 will have a configuration 22a enabling it to be received over the applicator tip of the holder with the lower edge of the container 22 resting upon the upper end of the collar 11b, as shown in FIG. 2.

In accordance with the invention, a locking member 24 is provided within the receptacle 18. The member 24 has a button or slide projection 26, a flange 27 and an intermediate groove 25. The slide projection 26 extends outwardly of the receptacle wall, the latter having a slot 18a therein permitting limited longitudinal travel of the locking member. The flange 27 engages and will slide along the internal wall surface of the receptacle 18 while the slide projection 26 engages the outer wall surface thereof.

The locking member 24 has a spade-shaped internally projecting end 28 which when the slide projection 26 is depressed, may be urged into the slot 17b in the ball 17a. This may be done immediately after the insertion of the ball 17a into the chamber 20 and will have the effect of expanding the ball 17a sufficiently to prevent withdrawal of the ball from the receptacle. It will. be understood that when the drive mechanism is operated to withdraw the pomade 21 from the container 22, frictional forces may be relatively high and the locking member 24 will positively prevent the disengagement of the respective parts during this operation.

Subsequently, when it is desired to replace a depleted lipstick pomade, it is necessary only to elevate the slide projection in the slot 18a until disengagement of the end 28 of the locking member from the ball 17a occurs. Thereafter, with the receptacle 18 in its extended position, the receptacle may be grasped without touching the pomade for disengagement from the drive mechanism.

It will be appreciated therefore, that the locking member of the invention enhances and makes positive, the trouble-free operation of the aforedescribed refill process. Since the embodiment presented herein is merely representative, reference should be made to the appended claims in order to appreciate fully the spirit and scope of the invention in which:

We claim:

1. In a lipstick container having a lipstick holder assembly and a lipstick pomade receptacle separably mounted together and drive means within the receptacle holder for axially moving the pomade receptacle, the improvement in combination therewith in connection and locking means for selectively maintaining: the holder assembly and lipstick pomade receptacle operatively connected comprising a ball member extending from said pomade receptacle and operatively connected to said drive means, a narrow slot cut into said ball member, a socket formed on said pomade receptacle and extending therefrom, said ball member separably held Within said socket to join the holder assembly and pomade receptacle together, and a locking device mounted on said pornade receptacle and having an actuable portion positioned externally of said pomade receptacle and an internal portion positioned Within said pornade receptacle and dimensioned for tight fitting engagement within said slot, said locking device mounted on said pomade receptacle to slide from a first position wherein said internal portion is separated from said ball member to a second position in locking engagement within the slot in said ball member.

2. A lipstick container according to claim 1 wherein said ball member and said socket are made of a deformable plastic material.
