Problems solved by technology

However, it is very difficult to control the protruding length of the flash, and the deviation of the protruding length of the flash is large. Therefore, although the inner plate with the flash protruding from the outer surface can also be manufactured, it is still necessary to correct the overflow of the gate mark after forming. Processes where material is processed or where it is necessary to check that there is no flash protruding from the outer surface
In the conventional method of manufacturing the inner tray by injection molding in this way, there is a limitation in cost reduction

Embodiment Construction

[0028] Below, refer to Figure 1 to Figure 7 An inner tray for cosmetics and a cosmetics container according to one embodiment of the present invention will be described. figure 1 The inner tray 1 for cosmetics in this embodiment is shown. The inner tray 1 has a cosmetic accommodating recess 10 filled with a powder cosmetic 2 . That is, the inner tray 1 has a bottom portion 11 and a side wall portion 12 rising upward from the peripheral portion of the bottom portion 11, and the bottom portion 11 and the side wall portion 12 form a cosmetic storage recess 10 opening upwardly inside it. Moreover, the flange part 13 is formed in the upper end part of the side wall part 12 toward the side. The flange portion 13 extends horizontally toward the side and is formed over the entire circumference.

[0029] It should be noted that the shape of the inner disc 1 is arbitrary, and in figure 1 In (a), as an example, a substantially rectangular inner plate in plan view is illustrated. Ho...

Abstract

The present invention provides a low-cost inner pan for cosmetics while ensuring strength, and a cosmetic container including the inner pan for cosmetics. The inner tray (1) filled with powdered cosmetics and cured is formed by sheet-forming a thick synthetic resin sheet with a thickness of 0.5 mm or more. Preferably, a plurality of protrusions are formed on the upper surface (11a) of the bottom surface (11) by sheet molding. In this case, it is more preferable that the lower surface (11b) of the bottom surface portion (11) is formed as a smooth surface without forming a concave portion at a portion corresponding to the convex portion of the upper surface (11a).

Description

technical field [0001] The present invention relates to an inner pan for cosmetics filled with cosmetics and a cosmetic container having the inner pan for cosmetics. Background technique [0002] In cosmetic containers such as compact containers, an inner pan filled with powder cosmetics such as foundation may be used. That is, powdery cosmetics are filled in the inner pan and solidified, and the inner pan is assembled into a cosmetic container for use. Such an inner disk requires strength. That is, when the inner disc is deformed, the solidified powder cosmetic will be cracked or chipped, and therefore, the inner disc requires sufficient strength. Therefore, the inner pan is often made of metal, but it may also be made of resin from the viewpoint of cost and weight reduction. Furthermore, when the inner pan is made of resin, it has conventionally been formed by injection molding. [0003] When the inner pan is formed by injection molding in this way, a gate trace, which...
