Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a heating container containing food used in a microwave oven or the like.

“Prior Art” Conventionally, in microwave ovens and the like, the completion of cooking of food has been notified by a termination sound by a timer or the like regardless of the actual heating state of food.

"Issues to be solved by the invention" Therefore, if the timer setting time is wrong, especially if food is contained in a container with a lid, it is necessary to remove the container from the microwave oven etc. It was inconvenient because I could not confirm whether it was cooked or not.

Therefore, an object of the present invention is to provide a heating container containing food, which can easily confirm the cooking state visually and is convenient for cooking.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a heating container containing food according to the present invention is a container body 1 having a top opening in which a cooked food A is stored, and an upper surface of the container body. When the both ends of the shape memory plate 5 folded in two are fitted to the respective rear edges of the lid 2 that closes the container, and the container body or the like is heated and the shape memory plate reaches a predetermined transition temperature, It is characterized in that the shape memory plate is expanded and deformed in the vertical direction so that the lid body can be opened.

"Operation" For example, in the non-heated state shown in Figs. 1 and 2, the shape memory plate 5 maintains the folded state and holds the lid body 2 closed.

On the contrary, when the container is heated by a microwave oven or the like, as shown in FIG. 3, when the shape memory plate 5 reaches its transition temperature, the container 2 is expanded and deformed in the vertical direction to open the lid 2.

[Example] An example of a heating container containing food according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 to FIG.
Each of the rear edge portions of a thin dish-shaped container body 1 in which is stored, and the same thin dish-shaped lid body 2 that closes the upper surface of the container body 1 are integrally coupled via a hinge portion 3 having a split pin section. ing. In the example shown,
The container body 1 and the lid body 2 have the shape of a scallop.

Engagement holes 4, 4 which are long in the left-right direction are formed in pairs in the up-down direction in the rear wall portions of the container body 1 and the lid body 2, and these engagement holes 4, 4 are formed in the engagement holes 4, 4, respectively. Both ends of the shape memory plate 5 folded in two in a U shape are fitted and inserted. The shape memory plate 5
For, either shape memory alloy or resin is selected.

Then, when the container body 1 or the like is heated in the above-mentioned closed state and the shape memory plate 5 reaches a predetermined transition temperature, the shape memory plate 5 is expanded and deformed in a vertical dogleg shape as described above. Lid 2
Is openable. Cooked food A described above
Is selected according to the transition temperature.

The container 1 and the lid 2 described above are molded and manufactured from a synthetic resin material having high heat resistance.

[Effect of the device] As described above, according to the present invention, the completion of the cooking of food can be visually confirmed by the automatic opening of the lid, so that the completion can be seen at a glance without erroneous confirmation of the completion. is there. Further, since the shape memory plate is folded in half, both ends of the shape memory plate are fitted to the rear edge portions of the container body and the lid body, respectively, so that the shape memory plate can be easily mounted and a large increase in cost can be avoided.

Claims (1)

[Scope of utility model registration request] 1. A shape memory plate (5) folded in two at each of the rear edges of a container body (1) having a top opening and containing a cooked food (A) inside and a lid body (2) closing the container body upper surface. When the shape memory plate reaches a predetermined transition temperature by heating the container body etc. by fitting the respective parts, the shape memory plate is expanded and deformed in the vertical direction, and the lid body is formed to be openable. A heating container containing food.
