Abstract

(57) [Summary] [Structure] A disposable heat-insulating heat-insulating container for foods, characterized in that an outer case made of corrugated cardboard is adhesively coated on the outer side of an inner casing made of heat-resistant resin molded into a predetermined container shape. [Effect] It is possible to provide an inexpensive and easy-to-manufacture heat insulating and heat insulating container that has substantially the same heat insulating and heat insulating effect as a conventional Styrofoam container, and can reduce heat and harmful gas generated during incineration.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to disposable food containers such as instant ramen with cups and take-away lunches that require heat insulation.

[0002]

[Prior art]

 In recent years, instant noodles in cups that can be eaten simply by pouring boiling water have rapidly become popular, and so-called take-out foods have been actively used as the food service industry has flourished.

Since foods of this type are not delicious unless eaten while they are hot, styrofoam (PSP), which has a high heat insulating and heat insulating effect, is generally used as a disposable container for storing this food.

However, when the Styrofoam container is disposed of as waste after use, it not only emits high heat during incineration and damages the incinerator, but also generates harmful gas and causes pollution. ing.

[0005]

[Problems to be solved by the device]

 In view of the problems of the conventional disposable heat insulating heat-insulating container for food, the present invention has the heat insulating heat insulating effect which is almost the same as that of the conventional Styrofoam container, and can reduce the heat and harmful gas generated during incineration. The present invention provides an inexpensive heat insulation container.

[0006]

[Means for Solving the Problems]

 The container of the present invention uses a laminated material having a two-layer structure in which a heat-resistant resin is used on the inside and a heat insulating and heat-resistant and impact-resistant corrugated ball is used on the outside.

That is, the present invention provides a disposable heat insulating and heat-insulating container for food, which is formed by coating an outer case made of corrugated cardboard on the outside of an inner case made of heat-resistant resin molded into a predetermined container shape. An embodiment of the present invention will be described below with reference to the drawings.

[0008]

【Example】

 FIG. 1 is a partially cutaway perspective view showing an embodiment of the heat insulation container of the present invention, wherein 1 is a vacuum-molded heat-resistant resin sheet having a thickness of about 0.2 to 1 mm, such as polypropylene, polyethylene, or vinyl chloride. The inner casing, which is formed by concavo-convex molding into a predetermined container shape by the method, is an outer casing made of corrugated ball material such as single-sided corrugated board, double-sided corrugated board, double-sided corrugated board, and tri-wall corrugated board.

This container is manufactured, for example, as follows. The inner casing 1 is molded in advance into a predetermined container shape (for example, a square horizontal section). In addition, it is preferable to mix an appropriate amount of calcium carbonate in the resin sheet forming the inner casing 1 so as to suppress the heat generated during incineration as low as possible.

The cardboard used as the outer casing 2 is composed of a liner on the front surface or the back surface and a central raw paper which is formed into a corrugated medium to form a three-dimensional medium, and is housed in a container among the various cardboards described above. It is appropriately selected depending on the content and weight of the food (in the example shown, the exterior single-sided hole is used). The surface of the liner, which is the outer surface of the container, may be printed with a store name, a product name, or the like, and may be further waterproofed by laminating or the like.

This corrugated board material is matched to the shape and size of the inner casing 1 which is the container body. For example, when the inner casing 1 is rectangular, cut lines and crease lines are provided at the four corners of the corrugated board material cut into a square shape. This is folded up in a box shape, adhesive is applied to the inner side surface of this box-shaped cardboard, and it is adhered to the outer bottom surface and four side surfaces of the inner case 1, and the outer side except the upper surface of the inner case 1 is completely covered with this cardboard. To coat.

A lid (not shown) having a two-layer structure similar to that described above may be fitted and covered on the upper surface of the container configured as described above. You may use the lid of.

Further, since the outer corrugated board is heat insulating and heat resistant, has impact resistance, and has a large burst strength, an outer casing 2 made of double-sided corrugated board (double-sided corrugated board, tri-wall corrugated board may be used) is manufactured, Even a laminated container can be used as a sufficiently warm container depending on the type of food to be stored.

[0014]

[Effect of device]

 The disposable heat insulation container according to the present invention is constructed as described above, and the hot food contained in the inner casing 1 is insulated on the outside by the heat insulating and heat insulating corrugated cardboard of the outer casing 2 so that it can be heated directly by hand. It also has good heat retention and can heat food in a container in a microwave oven.

In addition, even if this container is incinerated as garbage after using it, the use of the cardboard outer casing 2 can significantly reduce the total plastic use amount as compared with the conventional Styrofoam container. In addition to reducing the combustion heat generated during incineration, it also reduces the generation of harmful gas, is effective in terms of post-treatment, and has many advantages such as low cost, simple structure, and easy manufacture. .
