However, such a truncated cone-shaped convex portion reduces the flat surface from the upper wall surface of the lid portion and obstructs the sticking surface for sticking a barcode or a content display label. It will be. On the other hand, if part of the truncated cone-shaped convex part is omitted in order to secure a sufficient attachment surface, eggs stored in the body partly contact each other and the eggs are damaged, and the strength of the lid itself deteriorates. However, there is a problem that the shape cannot be maintained sufficiently.

Therefore, an object of the present invention is to secure a flat area sufficient for sticking a barcode or a label on the upper wall surface of the lid and to reliably prevent contact between the eggs stored in the body and rattling. The main object of the present invention is to provide a synthetic resin sheet-made egg container which is capable of sufficiently maintaining the strength of the container itself.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the egg container according to the present invention is an integrally molded product made of a thin synthetic resin sheet and has two or more egg storage recesses (2) of 6 rows,
(2a) and a partition wall (3) for separating these egg storage recesses, a body part (1) having a rectangular shape in plan view having (3a), and a hinge part (4) that can be inverted at one end of the body part (1) Consisting of a rectangular lid in plan view connected via (5), the lid (5) in the egg storage recess (2) of the body (1), the upper part of the egg stored in (2a) In a hen egg container in which a substantially frustoconical projection (6) filling the space formed between the two, (6a) is formed, the projections located at both lengthwise ends of the lid (5) ( 6a) and (6a) are formed in a half truncated cone shape with a flat surface facing the side of the lid short side, whereby a flat labeling area is provided on at least both ends of the lid upper surface.
(7), (7) are secured, and further the partition wall (3) that divides the egg storage recesses (2a), (2a) located at both lengthwise ends of the body (1).
The structure is such that a) and (3a) are formed higher than the other partition walls (3) ....

[0006]

The function of the egg container of the present invention is that the convex portions (6a) and (6a) located at both ends of the lid portion (5) in the longitudinal direction are formed in a half truncated cone shape so that both end portions of the lid upper surface are formed. Despite securing the flat labeling area (7), (7), the space due to the half cutout of the convex portion (6a) is compensated by the raised partition walls (3a), (3a), thereby As shown by 5, contact between the eggs stored in the egg storage recesses (2a) at both ends and rattling between the eggs are prevented, and the eggs can be effectively protected.

Since the additional concave portion of the body portion is not required to have a high transparency as compared with the lid portion, a lower shape similar to other concave portions for eggs (5 pieces × 2 rows or 3 pieces × 2 rows) is formed. Can be In that case, if a low rib that doubles as a reinforcement and a partition is also formed on the top wall of the lid additional concave portion, the ordinary egg surface with appropriate decoration is provided as a service item for each row. Additional storage is possible.
