Abstract

The present invention relates to a special container manufacturing method for solving the problem that the environmental hormone is eluted in the disposable food container, such as a conventional cup noodles container, harmful to the public health, instant food containers such as cup noodles or instant lunch box It relates to a manufacturing method of a disposable food container in which the aluminum thin plate is bonded to the inner side of the.

To this end, in the present invention, in manufacturing a disposable food container having an aluminum sheet attached to the inside of the container, the aluminum sheet is positioned on one side of the flat plate and the other side of the combined side is a synthetic resin or papers. It is an invention to make a multi-structure container with an aluminum material attached to the inside of the disposable food container by forming a flat plate and molding it to the frame of the container as it is.

Conventionally, harmful substances such as styrene compounds in cup noodle containers made of synthetic resin were eluted into food containers in hot broth. However, by using the container of the present invention, the aluminum sheet can block harmful substances. .

The present invention aims to contribute to the promotion of national health by facilitating the dissemination of such containers by making it possible to easily and economically and technically produce such types of disposable food containers.

The present invention relates to a method for manufacturing a disposable food container such as a cup ramen container or a lunch box container, the existing cup ramen container or lunch box is mainly composed of synthetic resin series that is weak to heat, when boiling water of 100 ℃ part of the container composition Toxic chemicals (such as styrene compounds) are dissolved, causing environmental hormones that are harmful to the human body.

In addition, paper containers have also recently been spreading, but with the cost problem, this paper is not 100% natural pulp, but because it is added to a material that can block the moisture absorption situation is difficult to fully trust the safety.

Accordingly, the present inventors applied a utility model (a disposable container using aluminum sheet or foil) filed by the user on August 11, 1998 to produce disposable food containers such as cup noodles containers in a more hygienic, safe and very economical way. This patent has been filed by improving the specific manufacturing method of harmless structure.

During the process of constructing a thin sheet of aluminum inside the container to prevent any harmful chemicals from melting into the container when putting hot fat-soluble or water-soluble substances such as 100 ° C into a disposable container (cup noodle container or lunch box container) By forming a plurality of plates in advance before molding to form and heat-molding it, it is not only easy to manufacture food packaging containers such as cup noodles containers, but also to make it harmless to health.

This means that one side to be the inner skin part is attached with a thin aluminum plate, and the other side to be the outer skin part to which it is bonded is attached to any one of the conventional disposable food container materials such as synthetic resin or paper, or a mixture of synthetic resin and paper. It is a multi-layered plate. In this case, in order to increase the handling strength of the aluminum thin plate, an aluminum thin plate to which strength reinforcing materials such as papers are attached may be used. An embodiment for making such a multi-structure plate and container is as follows.

Aluminum foil (including aluminum foil with strength reinforcing materials such as paper) and shell material are transferred to the plate by rollers, and this multipack is molded in a container manufacturing mold to produce disposable food containers. This multilayer plate manufacturing process and a container manufacturing process are possible with a series of continuous processes. Of course, it can be manufactured in a separate process. In order to bond the inner thin aluminum plate with the inner skin, the inner skin can be heated or adhesive can be applied between the inner and outer skins.

Hereinafter, described in detail by the accompanying drawings as follows.

1 is a state in which the plate of the aluminum foil (1) and the shell material (2) is combined to form a double structure as an example before the molding of the disposable food container in the present invention.

FIG. 2 is an aluminum sheet in which thin paper or vinyl is attached to one surface of the aluminum sheet to increase handling strength in order to reinforce the low tearing strength of the aluminum sheet.

FIG. 3 is a view of a multi-plate container material in which a container envelope material (existing disposable food container material) is arranged in layers in the material of FIG. 2.

Figure 4 is a state in which the plate of Figure 2 is molded in the form of a container in a mold. Here, the aluminum foil (5) is wrapped in a shell (4) such as synthetic resin or paper, and when the aluminum foil (5) pours boiling water in the container, it blocks the food and the shell (4) to elute harmful substances such as environmental hormones. Make sure that you can safely eat disposable food such as cup ramen.

FIG. 5 shows the plate of FIG. 3 formed in a container form in a mold. The purpose of the container or the effect of the container made of Figure 5 is the same as that of FIG.

Figure 6 is an example of a disposable food container manufacturing process in accordance with the present application, the aluminum sheet or reinforced aluminum sheet material and the shell material of Figure 2 is transferred to the plate to form a multi-layer plate. This multi-material plate is passed through a container molding mold to prepare a disposable food container. The temperature of the mold during heating is generally 200 ℃ ~ 250 ℃ when considering polystyrene, the most popular cup ramen material among synthetic resins, in consideration of the chemical properties of polystyrene. Since the temperature will be different, the temperature of the mold is set to 250 ° C ± 150 ° C. Of course, the mold on the side that is in contact with the aluminum sheet is more effective than the mold on the opposite side.

The bonding time of the aluminum sheet and the shell material can be arbitrarily selected from the time of manufacturing the multi-layer plate or the container molding. The bonding method may be a method of heating the aluminum sheet or applying an adhesive between the inner and outer shells. Of course, the adhesive is more environmentally friendly adhesives such as vegetable starch material, water than chemical bonds.

As the present invention, a disposable food container (cup ramen container, lunch box container, etc.) having an aluminum foil attached therein can be manufactured very easily, and economical and safety can prevent the harmful chemicals from being evaporated into food in these containers. . Thus, it can greatly contribute to national health.
