Description

Description: FIELD OF THE INVENTION The present invention relates to a method for producing a framed net placed on cosmetics contained in a compact cosmetic container, and a protective net used for the method. Related to nets with shaped pieces.

[Conventional technology]

Conventionally, a frame with a frame placed on top of a cosmetic contained in a compact cosmetic container is disclosed in Japanese Utility Model Application Laid-Open No. 63-163715.
No., published in Japanese Patent Application Publication No.

What is described in the above publication, as shown in FIG.
Viscous cosmetic 16 on the inner plate 15 of a compact cosmetic container
And a flexible net 1 whose peripheral portion is adhered to the frame 9 is placed on the cosmetic 16. When the net 1 is pressed with a sponge 17 or the like,
The viscous cosmetic material 16 in the material 15 oozes out from the mesh of the net 1 to the surface, adheres to the sponge 17, and is used for makeup.

Further, for molding the net with a frame, the net 1 is inserted in advance into a synthetic resin injection mold, and then the synthetic resin is injected into the mold to form the frame 9.
And a method in which the frame 9 is fixed to the periphery of the net 1 by welding.

[Problems to be solved by the invention]

When the net 1 as shown in FIG. 5 is not used,
It is stretched on the inner plate 15 so as not to generate wrinkles and the like, and when used, when pressed with the sponge 17, it flexibly expands and contracts according to the pressure, and the cosmetic 16 in the inner plate 15 is attached to the sponge 17. Things are good. Then, as described above, when the net 1 is made into a net 1 that can flexibly expand and contract, when the net 1 is inserted into a molding die, the net 1 is inserted so that wrinkles and the like do not occur in the net 1. Becomes difficult.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is possible to easily insert a flexible expanding / contracting net 1 of a cosmetic compact container into a mold so that a framed net can be formed. It is a technical task to obtain a net that can be inserted.

[Means for solving the problem]

The invention according to claim 1 is characterized in that a net 6 with a shape retaining piece formed by bonding a thin elastic piece 3 with poor elasticity to one side of a softly expanding and contracting net 1 in a releasable manner is used as a mold 20 for injection molding.
The mold 20 is closed, the mold 20 is closed, and then the molten synthetic resin is injected into the mold 20 to form the frame 9 and the frame 1 is formed on the net 1. 9 was welded and fixed to form a framed net for a compact container.

The invention according to claim 2 is a net 1 that flexibly expands and contracts;
A net with a shape-retaining piece for a compact container, comprising a releasably bonded shape-retaining thin piece 3 adhered to one side of the net 1 in a releasable manner.

[Action]

Since the net of the present invention is a net that expands and contracts flexibly, when it is attached to a compact container and pressed, the cosmetics largely stored under the radius net easily adhere to a sponge or the like.

Since the shape retaining thin piece 3 having poor elasticity is adhered to one side of the net 1 to form the net 6 with the shape retaining piece,
The net 1 is hard to bend.

Accordingly, when the net 6 with the shape retaining piece is inserted into the mold 20 for injection molding, it can be easily installed at a predetermined position in the mold 20 without wrinkles or the like.

〔Example〕

FIGS. 1 to 4 are views for explaining one embodiment of the invention according to claims 1 and 2. FIG. Claims 1 and 2
The net 1 according to one embodiment of the invention described above is formed by knitting using a synthetic resin yarn to form a flexible net 1
It is formed in. On one surface of the net 1, a non-elastic shape-retaining thin piece 3 made of polyethylene terephthalate having a thickness of 25 μm to 38.5 μm is releasably adhered to one surface of the net 1 by a polyester adhesive 2.
Is formed.

In one embodiment of the present invention, the net 6 with the shape retaining piece is cut into an elliptical shape, and the cut net 6 with the shape retaining piece is inserted into the female mold of the mold 20 and sucked to form the mold.
Set up so that it does not move within 20. Next, the male mold is brought into contact with the female mold, and the mold 20 is closed. Next, the molten synthetic resin is injected into the oval and annular cavity in the mold 20 to form the frame 9 and the net 6 with the shape retaining piece.
The molded frame 9 is welded and fixed to the net 1 to produce a framed net 12 for a compact container.

The framed net 12 is attached to an edge of a cosmetic container of a compact container, and the shape retaining thin piece 3 is peeled off from the net 1 when used. And the frame attached 9 can also be formed so as to slide down in the cosmetic storage dish as the cosmetics stored in the cosmetic storage dish decrease, and the shape-retaining flakes 3 It is also possible to form a flake of another material.

〔The invention's effect〕

Since the net of the present invention is a net that expands and contracts flexibly, when it is adhered to a compact container and pressed, it is easy to make the cosmetics stored largely under the radius net adhere to a sponge or the like.

Since the shape-retaining thin piece 3 having poor elasticity is bonded to one side of the net 1 to form the net 6 with the shape-retaining piece, the net 1 has a radius regardless of whether the net 1 is flexible. It is difficult to form.

Therefore, when the net 6 with the shape retaining piece is inserted into the mold 20 for injection molding, the net 6 with the shape retaining piece
Can be easily installed in a predetermined position in the mold 20 without any wrinkles or the like, and is easy to manufacture, and does not generate defective products. Therefore, a high-quality and inexpensive framed net for a compact container can be manufactured.
