Description

[Detailed description of the invention] (Field of industrial application) This invention is a device with a lid that can be used to store cooked or raw food in a freezer and then transfer it to a microwave oven for heating if necessary. Regarding containers.

(Prior Art and Problems) Conventionally, this type of lid and container are made of heat-resistant materials such as heat-resistant glass, and during freezing, the contents are sealed by a freezing seal of water poured into the joint surface between the lid and the container. I try not to let it dry out.

Also, during freezing, frost forms on the lid and inner surface of the container, making it difficult to visually see the contents you want to transfer to the microwave from the outside. impossible).

Therefore, it is necessary to open the lid to check the contents, but there is a problem in that in order to thaw the frozen seal, it is necessary to pour water over it or wait until it thaws.

Furthermore, if you heat the container in the microwave with the lid on and then remove it from the microwave after heating is complete, the inside of the container will begin to cool down and create a negative pressure, and the steam from heating will adhere to the area around the lid, resulting in a water seal. There was a problem that the lid was difficult to open.

Therefore, in order to solve this problem, it has been proposed to provide window holes in the lid and part of the container, and to close the lid so that the window holes match each other during heating. In order to prevent the contents from drying out, the lid must be closed so that the window holes do not line up, and the lid must be closed differently when freezing and when heating, which is inconvenient in use. be.

(Means for Solving the Problems) The present invention provides a container with a lid made of heat-resistant glass or ceramics, in which the lid has at least one window hole on the top surface, and a transparent wrap film is further provided on the inner surface of the lid. It's about pasting.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In Fig. 1, a lid 1 and a container 2 are molded from a non-metallic heat-resistant material such as heat-resistant glass, heat-resistant synthetic resin, or ceramics in order to enable heating in a microwave oven. window hole 1a
(two opposing ladder-shaped ones and a triangular one) are provided, and a fitting protrusion 1b that fits into the inner circumferential surface of the upper end opening of the container 2 is formed on the lower surface.

Also, put cooked food or raw food in container 2.
2, put the wrap film 3 on it, fit the lid 1 on it, and store it in the freezer.

Note that by pressing the wrap film 3 loosely onto the stored items, the degree of dryness of the stored items can be kept low during freezing.

When transferring the desired contents to the microwave oven, the frost that has adhered to the inner surface of the wrap film 3 during freezing is removed by rubbing the wrap film 3 from above with your fingertips, and the stored contents are passed through the wrap film 3 through the window hole 1a to the outside. It is not necessary to thaw the frozen seal and open the lid 1 as in the conventional case.

In addition, as mentioned above, by pressing the wrap film 3 loosely onto the stored object, even if vapor pressure is generated from the stored object during heating, the wrap film 3 expands and absorbs the vapor pressure, and after heating, When the container 2 is taken out, even if the temperature of the container 2 drops and the steam inside the container 2 condenses and contracts, the wrap film 3 returns to the loosened state again, so that the inside of the container 2 does not become under negative pressure as in the conventional case. There is no problem that the lid 1 cannot be opened due to folding. The lid 1 can be opened easily.

Note that the number and shape of the window holes 1a are not limited to the embodiments, and may be at least one or more.
Moreover, it can be made into any shape.

(Effects) The present invention provides a window hole on the top surface of the lid and adheres a transparent wrap film to the inner surface of the lid. (a) The stored items can be visually observed from the outside through the window hole and the wrap film; To make it possible to very easily sort out the contents being stored in a freezer without opening the lid, and to keep the degree of dryness of the contents low.

(b) The vapor pressure that increases during heating is absorbed by the expansion of the wrap film, and the container does not become under negative pressure or water seal after heating, and the lid can be easily opened after heating.

(c) There is no need to change the position of the lid during freezing and heating, making it easy to handle and use.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; FIG. 1 is an exploded perspective view of the lid and the container, and FIG. 2 is a side view of the lid. 1...Lid, 1a...Window hole, 3...Lap film.

Claims (1)

[Scope of utility model registration request] It consists of a lid made of a heat-resistant material such as heat-resistant glass and a container to which the lid can be attached and detached, and the lid has at least one window hole on its top surface, and a transparent wrap film is pasted on the inner surface of the lid. A container with a lid for both freezing and heating.
