Columnar projections 20 with a sharp front end are formed at the top of one side of projections 12, in pyramidal-trapezoidal projections 13, 15 formed at the crossings of partitions 11 and deep recesses 23 in which the columnar projections 20 are fitted are formed at the top of the other projections 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is manufactured by vacuum molding or blow molding a thin synthetic resin sheet and connects a body portion having a plurality of recesses for accommodating eggs and a lid portion through a bendable connecting portion. The egg container integrally connected is configured so as not to lose its shape.

[0002]

2. Description of the Related Art A conventional egg container, as shown in the perspective view of FIG. 4, is composed of a body portion 1, a lid portion 2 and a connecting portion 3 which connects these two portions flexibly and is transparent. A synthetic resin sheet is vacuum-molded or blow-molded to be integrally molded, and the body part 1 and the lid part 2 are provided with a plurality of recesses 12 and flanges 5 into which chicken eggs partitioned by partition walls 11 are inserted. . The string-like body 6 provided along the connecting portion 3 is pulled when opening the connecting portion 3.
It is for breaking.

A protrusion having a truncated pyramid shape is formed at the intersection of the partition walls 11.
13 and 15 are formed, and the tops of the protrusions 13 and 15 are flat, or, as shown in the cross-sectional view of FIG. 5, one of the truncated pyramidal protrusions 13 has a semicircular or conical shape. A protrusion 14 is formed, and a recess 16 with which the protrusion 13 engages is formed in the other pyramidal frustum-shaped protrusion 15.

After the eggs are placed in the respective recesses 12 of the body part 1, the lid part 2 is bent through the connecting part 3 and the flange part 5 facing the connecting part 3 is stapled or heat-sealed to seal. It has stopped.

[0005]

In such a conventional egg container, the projection of the truncated pyramid-shaped projection 13 in the sealed state is provided.
Since the engagement between 14 and the recess 16 of the truncated pyramid-shaped protrusion 15 is weak, and is easily displaced in the lateral direction, and is easily twisted, when a large number of egg containers are stacked and transported in a box or stacked at a store. In some cases, the container was deformed at an angle and deformed, and adjacent eggs were hit and damaged.

Therefore, the present invention was devised in order to obtain an egg container that is hard to lose its shape.

[0007]

In the egg container of the present invention, an openable and closable body portion and a lid portion are connected by a foldable connecting portion, and the body portion and the lid portion are partitioned by a partition wall. In an egg container of a synthetic resin sheet in which a plurality of recesses are formed, a columnar protrusion is formed on the top of one of the protrusions formed at the intersections of the partition walls, and the protrusion of the other is formed. The top portion is formed with a deep depression with which the protrusion is engaged.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the perspective view of the open state of FIG. 1 and the cross-sectional view of FIG. 2, an egg container 10 of the present invention is produced by vacuum molding or blow molding a thin synthetic resin sheet to form a plurality of eggs. It consists of a body part 1 and a lid part 2 which are integrally formed via a foldable connecting part 3 so as to hold them in a state of being separated from each other. Each of the portion 1 and the lid portion 2 is provided with a recess 12 which is partitioned by a partition wall 11 and accommodates a plurality of eggs.

A pyramidal trapezoidal protrusion is provided at the intersection of the partition walls 11.
As shown in the cross-sectional view of FIG. 2, one of the pyramidal trapezoidal protrusions is formed on the top of each of the protrusions 13 and 15.
At the top of 13 is a columnar protrusion with a sharp tip like a cone.
20 is formed, and a deep recess 23 with which the protrusion 20 engages is formed on the top of the other pyramidal frustum-shaped protrusion 15.

When the columnar projections 20 are formed by vacuum molding or blow molding, as shown in the cross-sectional view of FIG. 3, the thickness of the tip portion 21 parallel to the original sheet becomes thick, and the columnar portion 22 orthogonal to the original sheet 22. In the columnar protrusion 20, the wall thickness of the conical tip portion 21 is large, and the wall thickness of the columnar portion 22 is thin. Also,
If the deep depression 23 is formed so as to be surrounded by a circular projection 24 having a taper 25, the projection 24 has a large wall thickness and the recess portion 26 is formed to have an extremely thin wall thickness. When the protrusion 20 is inserted, the circular protrusion 24 having the taper 25 is elastically deformed and inserted, so that the columnar protrusion 20 is hard to come off.

When the eggs are packaged in the egg container 10 thus constructed, the eggs are put into the respective recesses 12 of the body part 1 and then the lid part 2 is bent through the connecting part 3 to fold the body part 1.
, And insert each columnar protrusion 20 into each depression 23,
The flange portion 5 is stapled or heat-sealed to seal it.

At this time, the pyramidal trapezoidal projections 1 formed at the portions where the partition walls 11 of the body portion 1 and the lid portion 2 intersect.
At the tips of 3 and 15, the protrusion 20 and the depression 23 do not engage deeply and are not displaced laterally, the mechanical strength is increased and deformation of the egg container can be prevented, and adjacent eggs collide. Will not be damaged.

[0013]

As is clear from the description based on the above embodiments, according to the egg container of the present invention, one of the pyramidal trapezoidal projections formed in the portion where the partition walls intersect each other. By forming a column-shaped protrusion on the top of the egg and forming a deep recess on the other side of the truncated pyramid-shaped protrusion, the egg is increased in mechanical strength without increasing the material used. Since the deformation of the container can be prevented, the packaged eggs can be prevented from being damaged.

Further, by sharply forming the tips of the columnar protrusions, when the lid portion 2 is overlaid on the body portion 1, the body portion 1 and the lid portion 2 can be easily positioned, and workability is improved. Can be improved.
