Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cooked food container for storing food to be cooked in a microwave oven.

[Conventional technology]

Recently, many foods have been sold that can be easily prepared by simply heating them in a microwave oven. This food (cooked food) is conveniently sold in a heat-resistant container and can be cooked while being stored in the container without being transferred to another container.

In such a container, it is necessary to form a ventilation hole 5 depending on the contents, and in such a case, the ventilation hole 5 is generally formed in the lid 2 or the like in advance.

[Problems to be solved by the invention] However, if the ventilation holes 5 are formed in advance, the sealing performance will inevitably be lost, which will cause an adverse effect on the preservation of the contents.

The present invention was conceived in view of these problems, and aims to provide a cooked food container in which ventilation holes 5 are naturally formed only during cooking.

[Means for solving problems]

Therefore, the container body 1 is composed of a bottomed cylindrical container body 1 having a flange 7 at the upper end of a cylindrical wall 6, and a lid 2 that is attached to at least the upper surface of the flange 7 to seal the container body 1.

Of the pasted parts, the outer part is made into a strong adhesive part 3 with a strong adhesive force, and the inner part is made easily by heating or by increasing the pressure inside the container body 1 by heating. A weak adhesion part 4 was formed with a weak adhesion force that could be easily peeled off, and a ventilation hole 5 was formed in the weak adhesion part 4.

[Effect]

In the state before cooking, the weak adhesive part 4 that forms the vent hole 5 is attached to at least the flange 7 of the container body 1, so the vent hole 5
is in a closed state. Therefore, the inside of the container body 1 can be kept in a sealed state (see FIG. 1).

When heated in a microwave oven, as the contents inside the container body 1 are heated, the container body 1 and the lid 2 become heated, and the pressure inside the container body 1 increases. Due to the heat of the container body 1 and the lid 2 or the increase in pressure inside the container body 1, the weakly adhered portion 4
peels off. As a result, the vent hole 5 becomes open, and the pressure inside the container body 1 becomes suitable for cooking (see FIG. 2).

〔Example〕

One embodiment is shown in FIGS. 1 to 3. In the present invention, at least the upper surface of the flange 7 is the adhesive part, but in this embodiment, almost the upper surface of the flange 7 is the strong adhesive part 3, and the area from the upper surface of the flange 7 to the upper end of the inner surface of the cylinder wall 6 is the weak adhesive part. It is set as wearing part 4.

The ventilation hole 5 is formed in the weak adhesion part 4 and is formed in the lid 2 in this embodiment, but it may be formed in the container body 1 or both the container body 1 and the lid 2. It's okay.

The weak adhesion part 4 may be one that is generally referred to as hot melt, which melts with heat and loses its adhesion, or it may be one that is peeled off due to increased internal pressure.

[Effect of idea]

As described above, according to the present invention, the inside of the container body 1 can be kept in a sealed state during transportation and sale before heating, so the preservation of the contents is good, and when cooking, Since the weak adhesive part 4 is peeled off and the vent hole 5 is opened, the pressure inside the container body 1 can be maintained at an appropriate level, thereby allowing the contents to be cooked deliciously. be.

Claims (1)

[Claims for Utility Model Registration] A container body 1 having a bottomed cylindrical shape having a flange 7 at the upper end of a cylindrical wall 6, and a lid 2 attached to at least the upper surface of the flange 7 to seal the container body 1. Of the pasted parts, the outer part is made into a strong adhesive part 3 with a strong adhesive force, and the inner part is easily fixed by heating or by increasing the pressure inside the container body 1 by heating. The cooked food container has a weak adhesive part 4 with a weak adhesive force that can be peeled off easily, and a ventilation hole 5 is formed in the weak adhesive part 4.
