Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg container in which a generally known synthetic resin sheet material is bulged to form a plurality of recesses for individually storing chicken eggs.

[0002]

2. Description of the Related Art A conventional egg container formed by bulging and molding such a synthetic resin sheet material is a container body in which a plurality of egg accommodating concave portions having a depth capable of accommodating a lower half of an egg are formed side by side as is generally known. And a lid body formed by arranging a plurality of egg accommodation recesses each having a depth capable of accommodating the upper half of the egg are formed in series, and the boundary between the container body and the lid body is a bent portion. . The method for packaging eggs is to store chicken eggs in the egg-holding recess of the container body, fold the lid body over the container body at the folding portion, and cover the outer peripheral edge portion of the container body and the outside of the lid body. Stop the edges with adhesive tape, stapler or other means and close the lid.

[0003]

Eggs packaged in such a general egg container in the state of being stacked and displayed in a store are from the outside to the inside of the egg accommodating concave portion of the lid body in which a plurality of reinforcing uneven ribs are formed. Since the size, luster and freshness of the egg must be seen through and confirmed, there is a problem that it is not easy to confirm. Further, even in a container in which the upper surface of the lid is a flat surface, the label is attached using this flat surface, so it is not easy to visually check the state of the egg inside from the outside.

On the other hand, after the purchase, the eggs are generally opened at home, and the eggs are taken out of the container one by one and arranged and stored in a predetermined storage place in the refrigerator. However, it has been confirmed that eggs may be contaminated with Salmonella, etc., and thus the method of storing eggs in a refrigerator in a naked state may cause contamination of other foods in the refrigerator. For this reason, people are calling out to store them in the refrigerator while keeping them in the packaging container. However, even in such a case, the conventional egg packaging container has a problem that it is difficult to completely prevent leakage of contaminating bacteria due to a gap formed between the outer peripheral edge portions of the container body and the lid. It was what I was doing. Further, due to this problem, there is a problem that it cannot be packed together with other foods for transportation.

Therefore, firstly, the present inventor can carry out the stacked display in a stable state at the store, and even in this stacked display state, it is easy to see the state of the eggs contained in the container from the outside of the container easily. Secondly, for the purpose of obtaining a container for eggs, secondly, there is no risk of contaminating the surroundings due to the excellent airtightness of the container in the closed state, even though it is such an egg container whose internal state can be easily confirmed. It can be displayed next to other foods in the display state at, and even if it is stored in the refrigerator after purchase, it can be stored as a container, preventing leakage of contaminating bacteria to other foods. The container according to the present invention has been developed for the purpose of obtaining a container for egg packaging that can be used.
