Description

A double container and method for manufacturing of it and apparatus for manufacturing of it}

The present invention relates to a double container and a method for manufacturing the same and a device for manufacturing the same, and more particularly, to a double container and a method for manufacturing the same by bonding an outer shell formed of a paper material to the outer peripheral surface of the container body made of polystyrene paper and The manufacturing apparatus is related.

In general, polystyrene paper is widely used as a packaging cushion or insulation for various disposable containers such as cup noodles containers and industrial products.

In the case of a disposable container used as a cup noodles container, as shown in Figure 1, the outer circumferential surface is used to coat the film 11 for the display of the trademark and printing of advertising text. However, printing such as advertisement text on the film 11 has a problem of lowering the print quality.

In addition, since the polystyrene paper container 10 is formed by blow molding, the bottom edge of the container is manufactured in a round shape 12.

As a result, the container 10 overlaps the container 10 so that the stability of the container is reduced, and the container 10 is swayed left and right even when a small amount of external force is applied to the container 10 when the consumer ingests the contained contents. It is inconvenient to use such as overflowing the contents.

The present invention was created to solve the above problems, and has the following object.

First, it is to provide a double container, a manufacturing method thereof, and a manufacturing apparatus for improving the printing quality such as advertisement text in a polystyrene paper container.

Second, to provide an improved double container, a method for producing the same and an apparatus for manufacturing the container so that the container can be stably placed.

Third, despite the high temperature contents contained in the polystyrene paper container, not only can the container be stably held, but also the double container with improved thermal insulation effect to maintain the temperature of the contents and its manufacturing method and its manufacture To provide a device.
