The container 1 includes a bag body 2 and a container opening sealing tool 3.
The bag body 2 is formed in a flat rectangular bag shape having an upper edge 4, side edges 5, 6 and a lower edge 7 using, for example, various synthetic resin films. In this embodiment, the upper edge 4 of the bag body 2 can be opened, and a region having a constant width from the upper edge 4 to the lower edge 7 is an opening 8.

Examples of the synthetic resin used for the bag body 2 include a polyester resin, a polystyrene resin, a polypropylene resin, and a polyethylene resin.
The container opening sealing tool 3 is formed in a plate shape made of a hard warping member having a convex warp that can be reversed. The thickness is, for example, 0.5 mm to 1.5 mm. As the hard warp member, a synthetic resin similar to that of the bag body 2 is preferably used. If both the bag main body 2 and the container opening sealing device 3 are synthetic resins, the container opening sealing device 3 can be easily and reliably fixed to the bag main body 2 by fusion of synthetic resins as will be described later. can do.

  In this embodiment, the container opening sealing device 3 is a substantially isosceles triangle having equal sides that are equal in length to each other, and a base that is longer than each equal side and the width of the bag body 2 (the length between the side edges 5 and 6). It is formed into a shape. A region having a constant width from the base of the triangle to the apex side is a fusion part 9 as an example of the base and the fixing part of the present invention. The container opening sealing tool 3 is fused to the outer surface on one side of the opening 8 of the bag body 2 through the fusion part 9. Thereby, the container opening sealing tool 3 is being fixed to the bag main body 2 in the attitude | position which the area | region of the top part side rather than the fusion | fusion part 9 which is a triangular base part protruded upwards as the drawer part 10.
