JPS6026982Y2 - Structure of compressed air vacuum forming container - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to the structure of a compressed air or vacuum-formed container, and for example, it relates to a packaging container for storing food, etc., and a container for placing food, etc. on it.

Conventionally known containers of this kind have been made by vacuum forming a synthetic resin sheet with aluminum vapor deposited on it.

For this reason, one side was a sheet surface and the other side was a mere aluminum surface, so it was impossible to eliminate the appearance of a simple container, and the decorativeness was also poor.

In view of these points, the present invention aims to provide a container whose texture is sufficiently decorative, which conventionally known containers could not be equipped with.

That is, the present invention is explained based on the drawing shown as an example).A container 1 formed by air pressure/vacuum forming includes a transparent synthetic resin film surface 2, a pattern portion 3 printed on the inner surface of this film, The film has a cross-sectional configuration of an appropriate metal layer 4 such as aluminum gold deposited on the inner surface of the film having the pattern, and a thermoplastic synthetic resin sheet surface 5 laminated to this metal surface.

Lamination may be achieved by welding, adhesive, or any other means, and refers to a metal surface and a sheet surface that are integrally joined.

A pattern may be applied to the sheet surface as desired.

In the case of Figures 2 and 3, the film was formed using pressure air/vacuum so that the film surface 2 was on the inside of the container, and in the case of Figure 4, it was molded so that the film surface 2 was on the outside of the container.
The present invention includes both forms.

In the former case, since the sheet surface 5 is on the outside of the container, the appearance is excellent in decorativeness due to the quality of the sheet or the combination of the desired pattern on the sheet surface, and the inside surface of the container is It is a transparent film layer, but because there is a metal surface deposited on the inside, the applied pattern appears to be embossed from the transparent interior, and at the same time, the parts other than the printed pattern are further embossed from the inside. In this way, the metal surface is exposed and visible, and the printed pattern and the metal surface are combined and mounted on the transparent surface, giving a texture to the inside of the container and providing excellent decorative properties.

This effect can be achieved by devising combinations of these and using patterns in various forms, such as using aluminum as the metal surface with a gold scroll pattern as the printed pattern, or using a vermilion pattern and gold metal surface. It is manifested as sufficient.

In the latter case, the appearance will be opposite to the above.

The shape of the container can be determined arbitrarily depending on the shape of the container and your preference.

In this way, according to the container of the present invention, it is possible to provide a container that has texture, decoration, etc. that are not found in conventionally known compressed air/vacuum formed containers.

According to this container, the printed pattern and metal do not appear on the surface of the container and are sealed within the cross section, so they do not flake off and are also hygienic.

As shown in Fig. 1, the container of the present invention is made by first printing a pattern 3 on a transparent synthetic resin film 2, then passing the printed film through a vapor deposition kettle and applying aluminum, gold, etc. to the printed side. - metal 4 is vapor-deposited, and then a synthetic resin sheet 5 is laminated on this metal surface to obtain a material, and this material is manufactured by compressed air or vacuum forming.

Initially, by depositing metal on the printed film without depositing metal on the sheet, inseparability between the printed surface and the metal surface of the film is ensured, and a single deposition process can deposit approximately -10,000 m. Materials can be obtained in a continuous state up to

This greatly improves manufacturing efficiency, compared to the conventional method of aluminum vapor deposition on a sheet, in which it was possible to obtain only a continuous material of approximately 500 r'r1 at most, as the diameter of the wrapping became large. It is.

Furthermore, laminating a flat metal surface and a synthetic resin sheet can be easily and reliably bonded and integrated.

Conventionally, it is difficult to print on the metal surface of a synthetic resin sheet made of aluminum vapor-deposited material and then apply a film over it. The reason for this is that the joint integrity cannot be maintained sufficiently.

Thus, the manufacturing according to the invention is easy and precise, and the container according to the invention is free from defects in its structure.
