Description

[Detailed Description of the Invention] The present invention relates to an improvement of a rotary payout type cosmetic stick container.

Many types of rotary feeding mechanisms have been proposed and put into practical use in cosmetic stick containers, but as shown in Figure 1, a very common structure is used for cosmetic stick containers.
A protrusion 3 protruding from the outer surface of the inner plate 2 that fits and holds the
is engaged with the spiral groove 5 of the spiral tube 4 and the guide groove 7 of the guide tube 6 to rotate the sleeve 8 and the rotary operation tube 9 which are connected to each other, and the decorative rod 1 is moved forward and backward by the screwing action. I was letting it happen.

This type of dispenser cosmetic stick container can be classified into two types: those in which the guide tube 6 and spiral tube 4 are molded from resin, and those in which the guide tube 6 and spiral tube 4 are molded from thin metal. The present invention is an improvement of a dispensing cosmetic stick container in which the dispensing mechanism is made of thin metal parts. Conventionally, the guide tube 6 was a bottomed cylindrical body with a notch cut out to become the guide groove 7 after press molding, but in order to reduce costs, the guide groove 7 was cut out.
A thin stainless steel plate with notches cut into both ends is wound around and used as the guide tube 6. In fixing the wound guide tube 6 inside the container, the inner bush 11 is further inserted and fitted until it comes into contact with the bottom 15 of the middle tube 10.

The present invention is a device that eliminates the inner bush 11 that fixes the middle tube 10 and the guide tube 6 in this well-known rotating cosmetic stick container, reduces the number of component parts, and further simplifies assembly. be.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The decorative stick 1 is fitted and held in an inner plate 2 and inserted into a wound guide tube 6. The spiral tube 4 is inserted and fitted into the inner wall of the sleeve 8, and is held between protrusions 12 and 12' provided around the guide tube 6, so that the helical tube 4 is attached to the guide tube 6 in a manner that cannot be removed from the sleeve 8 but is rotatable. It is covered with. The protrusion 3 protruding from the side surface of the inner plate 2 forms a guide groove 7 and a spiral groove 5.
is engaged in. Note that the guide tube 6 is inserted into a middle tube 10 that is inserted into and secured to the rotary operation tube 9.
A bent wall 1 bent from the bottom of this middle cylinder 10 at the lower part.
3 and the outer wall 14 and are firmly fixed thereto.

The embodiment of the present invention has the above structure, and in use, when the sleeve 8 is held and the rotary operation cylinder 9 is rotated as usual, the inner plate 2 has a protrusion 3 on its side surface that is aligned with the guide groove 7 and the spiral. Since it is engaged with the groove 5, it moves forward and backward, and the decorative stick 1 appears and disappears. The guide tube 6 includes a bent wall 13 and an outer wall 14 of the middle tube 10.
Not only does this eliminate the need for the conventionally used inner bush 11, but the guide cylinder 6 abuts and clamps the middle cylinder 10 up to the bottom during assembly, improving dimensional accuracy in height. This has the effect of preventing variations in the values. Further, when the rotary operation tube 9 is molded from resin, there is a risk of loosening due to the creep phenomenon, so the inner tube 10 and the rotation operation tube 9 are bonded together instead of being assembled by press-fitting alone. In this case, since the inner tube 10, guide tube 6, spiral tube 4, and sleeve 8 do not have a bottom in the dispensable cosmetic stick container of the present invention, even if a little more adhesive is put in due to variations in the adhesive, the adhesive will not be absorbed. Since the guide tube 6 escapes in the direction of the bent wall 13, the structure consisting of the middle tube 10, guide tube 6, spiral tube 4, and middle plate 2 is lifted up from the rotary operation tube 9 due to the excess adhesive. It also has the effect of reducing

Claims (1)

[Scope of utility model registration request] In a well-known rotating cosmetic stick container in which a thin stainless steel plate with notches cut into both ends to serve as guide grooves 7 is wound and used as the guide tube 6, the guide tube 6 is inserted into the rotary operation tube 9. This rotating cosmetic stick container is characterized in that it is inserted into a middle cylinder 10 to be fitted and fixed, and is clamped and fixed between a bent wall 13 bent from the bottom of the middle cylinder 10 and an outer wall 14.
