Abstract

PURPOSE:To form a pattern free from slippage of colors when a vacuum forming is effected, by placing a multi-layered sheet material with the hue of the surface layer different from the hue of the back surface layer in a vacuum mold with a contoured pattern. CONSTITUTION:A multi-layered sheet material 1 having a surface layer 3 and a back surface layer 4 with the hue of the layer 3 different from that of the layer 4 is placed in a vacuum mold 5 with a contoured pattern (a pattern of a flower 2) followed by vacuum forming so that the back surface layer 3 is spread and is made thinner correspondingly to the contoured pattern of the mold 5. Thus the hue of the back surface layer 4 is allowed to appear to the surface thereby a section having a pattern with natural touch and free from slippage of colors can be formed in a single step.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The invention relates to the pattern forming force method of the HA full-bottomed product [Background of the Invention and Prior Art] Force OJ plastic 1M resin sheet τ^empty It is well known that the surface of the rice cake is colored with a different color than the surrounding area, and the surface of the rice cake is colored differently from the surrounding area. concave body τ
0 as a sword ε that adds a trap color τ to the part of the shape -t, which is different from the surrounding area. For vacuum forming, (1) fallen scissors, (2) hot stamping,
(5) Ingiri Oriha (4) Print a different color on the 6 areas corresponding to the concave and convex pattern of Yoto Tamejime Rikata Shun on the sheet for kekigata, and make this nfA! Irregularities engraved on Iylc type fermentation 411
! In addition to (1) to (6) vacuum forming, coloring power is necessary, and accompanying Jigs and tools and engineering equipment were essential.

In addition, in (4) sword ε, it was difficult to match the print on the original sheet and the topography type, and because it was thin, it was a common use for the pattern etc.

[Purpose of the invention]

In view of the non-inventive situation, we have decided to provide a method for forming patterns that does not change the shape of the blade during vacuum forming and Il'J processes.6゜(mg of invention) aS) Non-inventive *means that a multilayer sheet material in which a surface layer that makes the hue is true is laminated with a multilayer sheet material formed by laminating a surface layer that makes the hue true is molded into a hollow-bottomed mold that is engraved with unevenness. As a result, the surface layer corresponding to the uneven pattern of the front side pattern appears on the next surface in the hue of the BM surface layer, and the pattern of the entire molded product is Φ. It is in the Formation Book.

Below, we will explain the invention from 8 to 22 by referring to the drawings showing the embodiments of the invention. Figure 1 shows a part of the product that is the invention, and it is formed by embossing a flower @ 2 on a part of the sheet material 1. The surface layer 6 and the surface layers 4 to 7 shown in FIG. The color of the ResorL version is different, and the thickness of the surface layer 6 is about 0.1 to 0.2 degrees U. Figure 6 shows the molding process using the sheet material 1f above. A vacuum forming mold 5 in which a flower pattern 2 is engraved on the surface of the sheet material 1.
Set it to 0 and perform vacuum forming.

FIG. 4 is an enlarged view of the pattern area A in FIG. 6. In the river where the pattern was engraved by vacuum forming, the surface layer 5 extends thinner to the other end than the surrounding area 11. As a result, when viewed from the front side, does the hue of the back side #i 4 look distinct through the front side #6 and is it different from the surroundings? ! −
It is also the one that makes Inutetsu Qin.

In addition, as an employee of the sheet material used in the invention, 0PVC,
Thermoplastic sheets such as acrylic can be used for ABS and polyolefin yarns. 5. The skin layer may be opaque and tΦ. 1. The color combination of the skin layer and the surface layer should be selected appropriately. As a mold with a strong heart, it can be used in both male and female ILO types.

〔Effect of the invention〕

As described above, inventive molding can be done in a single process including coloring of the patterned portion, and the young fruit is produced with a natural feel and a fine finish without any discoloration of the patterned portion.
