BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a metal skin forming mold for forming a metal skin.

[0002]

2. Description of the Related Art Conventionally, in a mold for forming a thong skin, a mold edge forming a mouth edge portion of the thong skin is formed in a straight line.

[0003]

The inside skin 30 formed by the conventional inside skin forming mold has a rim portion 31, 3
1 is linear (FIG. 6 (a)). Therefore, when the contents such as ice cream are stored in the storage portions 32 and 32 of the two inner skins 30 and 30, respectively, the rim portions 31 and 31 of the inner skins 30 and 30 are curved due to moisture or the like, and both ends 31 are bent.
Clearances 33 and 33 are formed in a and 31a (see FIG. 6).
(B)). Therefore, there is a problem that the contents are leaked from the clearances 33, 33.

[0004]

However, this invention solves the above problems because at least the long edge of the mold edge is formed in an arc shape.

That is, according to the present invention, in a mold provided with an uneven portion for forming the inside skin, at least the long edge of the mold edge for forming the concave edge of the inside skin is formed into an arc shape. It is a mold for forming skin.

[0006]

In this invention, since the mold edge is formed in an arc shape, the inside skin formed by the inside skin forming mold of this invention can form the rim portion in a concave arc shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS.

On one side of the substrate 1, two convex portions 2 and 2 for forming an inner skin accommodating portion are provided in three rows at a predetermined interval to form a convex mold 3 (FIG. 1). The central edges 4a and 5a of the long edges 4 and 5 of the rims of the convex portions 2 and 2 are end portions 4b and 5b, respectively.
It has a convex arc shape that is formed higher.

Next, two concave portions 9, 9 for forming an inner skin accommodating portion are provided on one side of the substrate 8 in three rows at predetermined intervals to form a concave mold 10 (FIG. 2). The long edges 11 and 12 at the rims of the recesses 9 and 9 are central portions 11a and 12a, respectively.
Has a concave arc shape formed deeper than the end portions 11b and 12b.

The convex mold 3 and the concave mold 10 form a skin forming mold 15. In the above, the convex mold 3
And the concave mold 10 are formed so as to fit with each other. Further, the central portion 4a of the long edge 4 of the convex mold 3 is formed in a convex arc shape as compared with the straight line shown by the chain line as shown in FIG. 3, and the degree of curvature is formed by the material of the inner skin.
It is formed into a predetermined shape. Similarly, the long edge 11 of the concave mold 10
The degree of curvature of the convex mold 3 also matches the shape of the convex mold 3 (FIG. 4).

Next, the use of the inner skin forming mold 15 based on the above embodiment will be described.

A material is put also in the concave portion 9 of the concave mold 10, and the convex mold 3 is combined with the concave mold 10 with the convex part 2 side facing downward to form the inner skin 16. As shown in FIG. 5A, the inner skin 16 formed by using the inner skin forming die 15 has a shape in which a rim 17 is curved in a concave arc shape. If you combine two skins 16, 16 and the edges 17 and 17,
The two inner skins 16, 16 create a gap 18. Next, when the inside skins 16 and 16 in which the contents such as ice cream are stored in the storage units 19 and 19 are put together, FIG.
As shown in FIG.
Deforms, becomes straight and is sealed.

In the above-mentioned embodiment, the convex portions 2 and 2 and the concave portions 9 and 9 for forming the accommodating portion are provided in two rows of three rows, but the desired number, shape and interval may be provided.

In the above embodiment, only the long edges 4 and 5 of the die edges of the convex die 3 have a convex arc shape, but the long edges 4 and 5 and the short edges 6 and 7 may have a convex arc shape. it can. In this case, naturally, together with the convex mold 3, the long edges 11 and 12 and the short edges 13 and 14 of the mold edges of the concave mold 10 are also formed in a concave arc shape.

[0015]

According to this invention, since at least the long edge of the mold edge is formed in an arc shape, the mouth edge of the inside skin formed by the inside skin forming mold of this invention is formed in a concave arc shape.
Therefore, when the contents are put into the two inner skins and combined, the inner skin is deformed due to moisture or the like and the rim is sealed, so that the contents are prevented from leaking from the rim. .
