2. Description of the Related Art In recent years, a food pack in which a main body and a lid are integrally formed using a film-shaped transparent sheet material of a synthetic resin as described above as a material is also used as a packaging container for food hygiene management, transportation and sales. It is frequently used as a storage container for fresh vegetables, processed foods and the like. Thus, as a means for sealing the lid after the package is stored in the food pack, a flat thin edge is formed by continuously projecting outward from the periphery of each opening where the body and the lid come into contact. However, since the flat narrow edge itself does not have a hooking means for the main body and the lid, when the food is stored in the main body and the lid is closed, the narrow edge of the main body and the lid are overlapped. The cover is fixed with adhesive tape or stapled to prevent the lid from opening. In addition, two sides of each corner of the opening peripheral portion of the main body and the lid are formed with a concave portion on one side and a convex portion on the other corner portion fitted with the concave portion, and these irregularities are fitted. Thus, the main body and the lid are completely fitted to each other, thereby stabilizing the contents and improving the hygiene management at the time of transporting the food.

[0003] However, as the conventional sealing means for the main body and the lid, in the former, the food is stored in the main body, and then the lid is bent, and the main body and the periphery of each opening of the lid are polymerized and an adhesive tape is used. When stopping or hooking on a stapler etc., the work at the time of closing the lid is easy, but when opening it, peel off the adhesive tape or mix a thin metal piece such as a stapler into the food of the contents It has to be done with great care to remove it without care, so it takes a considerable amount of time and is not very popular with consumers.

[0004] In the latter case, when the irregularities formed on the four peripheral surfaces of the opening edges of the main body and the lid are completely fitted, stable transport and display of the stored items are possible. On the other hand, when the irregularities formed on the four peripheral surfaces are completely fitted, among the irregularities formed on the peripheral edge of the main body and the lid and the like, first, each corner of the connection side where the main body and the lid are connected to each other After fitting the irregularities provided in the first, the irregularities provided in each outer peripheral part must be fitted, and the worker who handles a large amount of fresh vegetables or processed products every day must After the lid is superimposed on the main body so that the irregularities provided at the corners of the connection sides to be connected are fitted first, the irregularities provided on the outer peripheral portion are superimposed to fit so that the outer periphery thereof is Even if only the parts are fitted with fingertips, these are Although the two corners of the peripheral part are completely fitted, one of the corners of the connection side where the main body and the lid are connected escapes, and one of the corners remains open. The product is open to the whole surface and the product jumps out and loses its product value.Complete cover of the lid is also available for fresh vegetables or processed products for consumers or consumers. He is seeking a food pack that can be easily opened.

[0005]

SUMMARY OF THE INVENTION An object to be solved by the present invention is to eliminate the need for a special device when the lid is bent from the connection side and superimposed on the main body after storing the contents in the main body.
