Description

  The present invention relates to a food storage cup.

Conventionally, cup-type containers for storing foodstuffs such as instant noodles and snacks can be opened so that the foodstuff as the contents can be taken out by lifting up a thin-film lid attached to the upper surface of the opening. It is known (see, for example, Patent Document 1).
Once the lid is peeled off from the cup-type container, the opening cannot be closed again, so hot water is injected after opening and the opening is kept closed again to prevent heat dissipation. Even if he tried to go, he couldn't hold the lid securely, so he put a spoon up.
In addition, when it is desired to prevent the contents remaining in the cup after opening from unexpectedly popping out, a method has been proposed in which a lid is attached to the cup type container using an adhesive tape to close the opening ( Patent Document 2).

JP 2007-176521 A Japanese Utility Model Publication No. 7-24767

  However, the spoon placed on the cup to hold the lid was unstable and could fall or not fully close. In addition, when water adheres to the surface of the cup body and the lid, or when surface treatment is applied, the adhesive tape (as in Patent Document 2) cannot be attached to the cup body and the lid. There was a drawback that the opening of the cup could not be closed.
