Description

  The present invention relates to a paper container for putting contents such as various foods therein and cooking by heating in a microwave oven.

In recent years, individualization has progressed, for example, many foods filled and sealed in retort pouches etc. are transferred to a tray-shaped microwave cooking paper container, covered with a microwave oven, and then cooked in a microwave oven to eat. In this case, the food is heated, the internal pressure is increased by the generated water vapor, and the lid portion of the paper container is swollen in a convex shape. When the used microwave oven paper container has a shape as shown in FIG. 3, the handle (52, 53) and the top plate (16) provided at the tip of the side plate when heated by the microwave oven. High temperature water vapor (61) leaks in the direction of the grips (52, 53) from the gap formed between the two parts and the high temperature when the paper container is taken out of the microwave oven by grasping the grips (52, 53) by hand. There was a risk of burns with water vapor.

  In the microwave oven cooking paper container of the present invention, at least one side of the rectangular bottom plate is continuously provided with a side plate having a recess at the tip via a ruled line, and the other side is a rectangular side plate, A top plate and a flap are successively connected via a ruled line, and a rectangular side plate on the short sides on both sides of the bottom plate, a bottom plate for a handle that serves as a handle when using a paper container, and a position close to the tip. A microwave oven cooking paper container made of blanks each having a handle upper plate having a notch for hooking on a face plate, each being connected via a ruled line, wherein the lower handle plate and the upper handle plate are folded inside. The microwave oven cooking paper container is heated and cooked because it is stored in a paper container and the top plate is folded back through the ruled line and the flap is folded back and inserted through the ruled line. High temperature steam generated in it by using as blown toward the center of the paper container can be safely removed from the microwave oven by grasping the handle portion after cooking.

The microwave cooking paper container of this invention is demonstrated below along embodiment. FIG.
These are top views which show one Embodiment of the blank used for the microwave oven cooking paper container of this invention, A blank (1) is along a ruled line (30) on one long side of a rectangular bottom board (10). A side plate (12) having a recess (11) at the tip is continuously provided, and a rectangular side plate (13), a rectangular top plate (16), and a flap (17) are ruled lines (31) on the other long side, respectively. , A ruled line (32), a ruled line (33), and a rectangular side plate (14) on one short side of the bottom plate (10), a lower plate for the handle (18), and a position close to the tip. An upper plate (20) for a handle having a notch (22) having a predetermined shape for hooking on the top plate (10) is successively provided via a ruled line (34), a ruled line (35), and a ruled line (36). A rectangular side plate (15) on the short side, a lower plate for grips (19), close to the tip An upper plate (21) for a handle having a notch (23) having a predetermined shape for hooking on the top plate (10) at a position is successively provided via a ruled line (37), a ruled line (38), and a ruled line (39). Furthermore, tongue pieces (24, 25, 26, 27) are connected to the four corners of the bottom plate (10), respectively, and (b) and (c) are one embodiment of the microwave cooking paper container of the present invention. The microwave cooking paper container (2) is composed of the blank (1), and has a handle lower side plate (18) and a notch top (22).
