DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a mold for forming a dispensing container such as a bar-shaped cosmetic product having an undercut all around.

[0002]

2. Description of the Related Art A dispensing container such as a stick-shaped cosmetic product, such as a lipstick container, has an inner plate for attaching a lipstick, and a vertical groove for receiving the inner plate and penetrating projections provided 180 degrees symmetrically around the inner plate. It consists of an inner cylinder, an outer cylinder having a spiral groove that guides a projection that penetrates the vertical groove (guide cylinder), and a cap that is attached to and detached from the outer cylinder. The rotating operation part is integrally molded or separately molded. By the way, the outer cylinder is a part that is visually recognized by a user when the cap is removed, and occupies a large weight in the appearance, appearance and commercial value of the container.

Conventionally, a plastic cylinder is generally used as the outer cylinder, but it cannot be denied that it lacks a sense of quality. As a countermeasure against this, there is known a case in which a metal tube C is externally fitted to a plastic outer tube A 'as shown in FIG. In this case, the metal cylinder is formed with a short flange-shaped top edge D projecting inward in the radial direction by deep drawing, and a sense of volume is created by the short flange-shaped top edge D, and the top end surface E of the outer cylinder A 'is formed. Can be covered so as not to be seen from above, so that the appearance and appearance can be improved and a sense of quality can be exhibited. However, since a metal tube is used as a separate part, manufacturing costs and assembly costs increase, and it is inevitable that a large increase in cost is caused.

As a countermeasure, it is advantageous if a short flange-shaped top edge is formed on the outer cylinder itself. However, in this type of container, the inner cylinder and the outer cylinder are relatively rotatable, and the inner cylinder has at least one longitudinal groove reaching the top edge, and a thick outward flange is provided at the top edge. The outward flange is locked by a step formed on the inner surface of the outer cylinder top. Therefore, in order to obtain a short flange-shaped top edge as in the case of the metal cylinder in a plastic outer cylinder, it is necessary to form an entire circumference undercut portion, and it becomes impossible to remove the mold after molding. For this reason, conventionally, in the case of plastic, as shown in FIG. 26, the outer cylinder A 'has to be a straight one whose top is not bent inward. Even when the application was performed, the color of the plastic cloth on the top end surface E of the outer cylinder A 'and the entire top surface of the inner cylinder F was visually observed as it was from above, and a sense of volume and luxury could not be exhibited.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems. A first object of the present invention is to provide a voluminous feeling or high-grade feeling having a short flange-like top edge portion while being made of all plastic. It is an object of the present invention to provide a method of forming a delivery container such as a bar-shaped cosmetic product having an undercut all around which can easily produce a cylindrical body provided with the above. A second object of the present invention is to provide a compact and relatively simple mold suitable for carrying out the method.

3 is separated from the fixed side template 504, and the fixed side template 504 is
Are separated from the stripper plate 505. FIG.
When the upper core stripper plate 503 is raised as described above, the upper core 1 is extracted from the holes 50 of the molding unit 2 using the inclined surfaces 82 of the four first slide cores 8 as guides. With the movement of the tapered portion 11, the wedge action on the first slide core 8 is weakened, so that the four second slide cores 9 are pushed out in the radial direction by the pressing force of the springs 10, and the second slide core 9 is pressed. Since the tapered surfaces 81 of the first slide core 8 are in contact with the vertical surface 92 of the 9, the four first slide cores 8 are also pressed and moved in the radial direction. As a result, as shown in FIGS.
The flanges 80 and 90 for forming the undercuts a and 9b are disassembled and narrowed from the annular state, and all the flanges 80 and 90 are displaced inward from the inner surface of the cylindrical portion of the product cylindrical body A, and the holes in the base plate 5 are removed. Located within 50.

As a result, the core is released from the undercut around the entire circumference. Next, if the fixed mold plate 504 is separated from the stripper plate 505, the product cylinder A fits on the outer periphery of the inner core 4 as shown in FIG. It is left in a state. At this time, since the flanges 80 and 90 for forming the undercut are located in the holes 50 of the base plate 5, the short flange-shaped top edge d of the product cylinder A is not damaged. Thereafter, when the ejector plate 509 is raised, the inner core 4 is rotated by the spiral groove, so that the product cylinder A is released. As described above, the cylindrical body A as a resin-made rod-shaped cosmetic container having the entire circumference undercut c below the short flange-shaped top edge d is obtained in one step.
Then, a metal-colored film may be applied to the outer surface of the product cylinder A by vacuum evaporation or the like, and a transparent resin coat may be applied. The obtained product is as shown in FIG. 24, and has an appearance as if it were decorated with a metal tube, and the short flange-shaped top edge portion d creates a voluminous feeling, thereby giving a sense of quality.
