設してなるものである。In the drawings, reference numeral 1 denotes a food storage container according to the present invention, which is a container formed by molding a polycarbonate resin sheet having a thickness of 0 or 5 mm into a rectangular shape in a plan view having four arcs at four corners by a vacuum press forming machine. The container body 2 includes a main body 2 and a lid 3. A convex edge 4 having a substantially hat-shaped cross section is provided around the peripheral end of the container main body 2. The convex end of the container main body 2 is formed at the peripheral end of the lid 3. The container main body 2 and the lid 3 are provided with a convex edge 5 having a substantially hat-shaped cross section provided with a hollow portion 5a fitted to the edge 4.
And the width of the opening 5b of the cavity 5a formed by the convex edge 5 of the lid 3 is set to the width of the convex edge 4 of the container body 2. The width is slightly smaller than the top 4a, the width of the ceiling 5c is the same as the width of the top 4a, and the inner edge 4b of the top 4a is formed in an arc shape. At the corner portions, horizontal tongue pieces 6, 7 for opening the lid protrude from outer edge portions a, a 'of the respective convex edges 4, 5 constituting the sealing portion A, and the tongue pieces 6, 7 are base portions. 6a, 7a
Are overlapped with each other, the tip portions are shifted from each other in different projecting directions, and the portions 6 do not overlap with the tip portions.
b, 6b, the non-overlapping part 6b on the container body 2 side is disposed on the left hand side, and the non-overlapping part 7b on the lid body 3 side is disposed on the right hand side.

The opening 5b of the hollow portion 5a
a top 4a comes into contact with a ceiling 5c of the same width, and the width of the opening 5b is elastically restored by the disappearance of the expanding force due to the passage of the inner edge 4b, so that the convex edge of the container body 2 By pressing the skirt 4c of the base 4, the protruding edge 4 fits into and closes to the cavity 5a to seal the container body 2, and when the lid is opened, a non-overlapping portion 6b formed at the tip of the tongue pieces 6, 7 ,
7b is picked up with the right and left fingertips, and the tongue 7 of the lid 3 is lifted to open the lid. The so-called frozen food stored and frozen and stored in the container 1 is cooked in a microwave oven. Then, as the lid 3 is pushed up by evaporative expansion of internal moisture and the like due to heating, the width of the opening 5b of the cavity 5a formed by the convex edge 5 of the lid 3 in the sealing portion A is expanded, and The lid is easily opened in combination with the expansion force (FIG. 6).
