Problems solved by technology

Carrying out food in this way is because in the case of using a container containing a metal layer in a microwave oven, there is a possibility that "sparks are generated on the metal layer exposed from the flange end of the container, which may cause the container to burn, thereby affecting the food contents." quality" etc.

Embodiment 1

[0182] Manufactured by the "manufacturing method using injection molding" explained in the preceding paragraph figure 1 Shown is a container 1 for food. The outer container 3 is an outer container with a thickness of 120 μm formed by using aluminum (A8021-O material), and the molten polypropylene resin heated to 230°C is injected into the cavity for molding, thereby injecting the molten resin into the outer container 3 The outer surface of the inner container 2 with a thickness of 1.0 mm is overlapped with the outer container 3 with a thickness of 120 μm, and the two containers 2 and 3 are tightly integrated and can be separated. Container 1 for food.

Embodiment 2

[0186] Manufactured by the "manufacturing method using pressure forming" explained in the preceding paragraph image 3 Shown is a container 1 for food. The outer container 3 is an outer container composed of a three-layer laminate of crystalline polypropylene layer (inner layer) (30 μm) / aluminum layer (120 μm) / crystalline polypropylene layer (outer layer) (200 μm); made of resin The sheet 70 is a polypropylene sheet with a thickness of 1.0 mm, and the resin sheet 70 heated to 145° C. is laminated on the inner surface of the outer container 3 to perform pressure molding to manufacture the inner container 2 with a thickness of 1.0 mm. The outer surface of the container 1 is superimposed on the outer container 3 with a thickness of 350 μm, and the two containers 2 and 3 are tightly integrated and can be separated.

Embodiment 3

[0188] As the outer container 3, the outer container was the same as in Example 2, except that an outer container with a three-layer laminate structure of polyethylene layer (inner layer) (30 μm) / aluminum layer (120 μm) / polyethylene layer (outer layer) (200 μm) was used as the outer container 3. way, get image 3 Shown is a container 1 for food.

Abstract

The utility model relates to a food container. The food container 1 is composed of a resin inner side container 2 without a metal layer and an outer side container 3 with a metal layer 52. The two containers 2 and 3 are combined into a whole in the way that the outer surface of the inner container 2 and the outer side container 3 are overlapped, and the two containers can be separated. According to the structure, on one hand, the food container has the advantages that the gas barrier property of the container is excellent; on the other hand, sparks can be avoided when a microwave oven is used for heating the container, high temperatures are not likely to happen to the container, the food heating efficiency is high, and the condition that food is not evenly heated is not likely to happen.

Description

technical field [0001] The present invention relates to a container for food, which is a container for putting liquid or solid food therein, and which can prevent sparks from being generated when heated by a microwave oven. Background technique [0002] Containers containing a metal layer are widely used as food containers because of their excellent gas barrier properties. However, when heating food filled in such a metal layer-containing container with a microwave oven, conventionally, the food is moved to a glass container or a ceramic container, and then heated in a microwave oven. Carrying out food in this way is because in the case of using a container with a metal layer in a microwave oven, there is a possibility that "sparks are generated on the metal layer exposed from the flange end of the container, which may cause the container to burn, thereby affecting the contents of the food." quality" etc. [0003] In order to solve the above-mentioned problems when using a...
