Description:

This invention relates to holders for lipstick and other materials and has for its object to provide a simple and inexpensive means for locking the carrier in extended position, with an automatic release for the carrier lock which is responsive to movement of the carrier actuator.

One expedient in the prior art has been to lock the carrier in extended position by providing the longitudinal casing slot with one or more lateral offset portions, into which the carrier actuator may be laterally shifted. In this old type construction both the locking and the unlocking requires a separate transverse movement of the carrier pin in addition to the usual longitudinal movement. While comparatively simple for a mechanic, such lateral shifting is as difficult for some women to learn as is the movement of a gear shift lever in a car.

In order to overcome this objection, the present invention makes the locking and unlocking automatic, thereby simplifying the construction and better adapting it to the feminine need. Specifically a series of teeth are arranged longitudinally within the casing and a spring detent for cooperation with these teeth is fixed to the carrier and normally arranged to engage the teeth. On inward pressure of the actuator pin, as is done in the usual manipulation, the spring detent is released from engagement with the teeth. Referring to the drawing: Fig. 1 shows a lipstick holder embodying this invention and with the cover in place.

Fig. 2 is the view corresponding to Fig. 1 with the cover removed.

Fig. 3 is a view of the same lipstick with the carrier partially extended, and the casing broken away to show the carrier.

Fig. 4 is a longitudinal section through the holder of this invention with the carrier partially extended.

Fig. 5 is a section on the line 5-5 of Fig. 4.

Fig. 6 is a perspective showing a lipstick holder in which this invention is embodied.

Fig. 7 is an exterior perspective of the carrier showing the spring detent.

Fig. 8 shows the capped lower end of the casing just before the transverse strip has been bent or deformed so as to lie straight, and expansively wedge the sides of the casing tightly into the cap.

The casing 10 is for purposes of illustration shown as being of rectangular cross-section.

Some usual form of cover if has a friction sliding fit over the casing to close the open upper end of the casing and also the longitudinal slot 12, and hold the actuator 15 and carrier 13 for the lipstick material 14 in retracted position. The actuator 15 for sliding the carrier 13 is provided with two legs or studs 16 which engage the perforations 20 in the carrier 13. These studs are shouldered where they enter the perforations 20, so that when the inner ends 23 of these studs are upset or bent over, the actuator button 15 is secured to the carrier.

Each side of the slot 12 is provided with an inwardly extending flange 17, in which are cut the teeth 18, shown in Figs. 4 and 6. These teeth are cut and the flange 17 turned in, before the casing is bent into the rectangular cross-sectional form illustrated. For cooperation with these teeth 18, the carrier is provided with a detent 19 on the lower end of the spring finger 21. This spring 21 normally presses the detent 19 outwardly into engagement with one of the teeth 18 and is pressed inwardly by the operator pressing the actuator 15 as is usually done in moving the carrier. The teeth 18 on the flange 17 project into the casing only a short distance, yet enough to cause a possible looseness or chatter due to the clearance between the carrier and inside of the casing. Therefore, in order to provide a better fit for the carrier, a pair of projections 24 are stamped outwardly as shown in Fig. 7, these projections being of about the same extent as is the flange 17, with its teeth 18. It will thus be seen these projections 24 slidingly engage the front wall of the casing on each side of the teeth 18 to give a good fit.

At ordinary temperature, the cosmetic material 14 is so soft that no difficulty is experienced in deforming or compressing it when the spring portion 21 is moved inwardly to disengage the detent 19 from the teeth 18. In very cold weather, however, the material 14 may be so hard as to make it difficult for the detent to disengage the teeth unless some means is provided to insure such occurring. For this purpose, a carrier is provided with a transverse inwardly extending strengthening rib 25 at the supported end of the spring finger 21. This rib not only serves to stiffen the spring 21 and assist in keeping the detent projecting outwardly, but also serves as a means to compress the lower end portion of the lipstick 14 as it is inserted into the carrier 13 to thus provide a clearance or space in back of the spring 21 so that the spring may be moved inwardly, even in cold weather. The cosmetic material 14 is supported on an inwardly projecting platform 22 stamped out of the rear wall of the carrier. 85 As shown in Fig. 8, the lower end of the casing 10 is provided with a transversely extending strip 7S bent inwardly from the rear casing wall. The free or front end of the strip 26 is r slightly bent up as illustrated. After the casing has been inserted in the cap 28, a tool is inserted into the casing from the top for the purpose of flattening out or straightening the little bent up end 27. This has the effect of tightly and expansively wedging the casing walls against the sides of the cap 28 and maintaining them permanently and tightly secured to the cap 28 without recourse to soldering or welding.

Among the advantages of this invention may be mentioned the automatic locking of the lipstick in substantially any degree of its extended position, together with the automatic release of the carrier in response to normal pressure upon the actuator 15 which moves the spring detent 19 inwardly and out of engagement with the teeth so that the carrier may be freely moved. The locking of the carrier in extended or partially extended position is desirable in order that the cosmetic may be used without the necessity of holding the thumb on the actuator 15. Due to the shape of the teeth illustrated in Fig. 4, it will be appreciated that the carrier may be moved upwardly by an end thrust on the actuator, and without the necessity for an inward pressure upon the actuator and spring. In this last case, the spring detent is continually engaged with the teeth. While the carrier may be moved up without disengaging the detent, it will be understood that the reverse is not true and the detent must be disengaged from the teeth before the carrier mnay descend. As shown in Fig. 5, the teeth 18 are arranged on each side of the casting slot 12.

The projections 24 on the carrier assist in firmly positioning the carrier within the casing without undue lost motion. It will be noted that the maximum movement of the spring 21 occurs adjacent the detent 19, which is well below the cosmetic support 22. The manner of permanently attaching the cap 28 without the use of solder and the like deserves attention, as such is quickly and easily performed.
