Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg packaging in which a thin synthetic resin sheet is manufactured by vacuum molding or blow molding, and a body part for inserting eggs and a lid part are integrally connected through a flexible connecting part. With regard to the container, in particular, a label indicating the producer and the quality can be attached so that the egg does not collapse even when stacked in a packaged state.

[0002]

2. Description of the Related Art A conventional egg packaging container 10 has a body part 1, a lid part 2, and a connecting part 3 for flexibly connecting these two parts, as shown in a closed state in a perspective view of FIG. And a transparent or translucent synthetic resin sheet is integrally molded by vacuum molding or blow molding, and the body part 1 is partitioned by a partition wall and a projecting portion provided at a crossing part of the partition wall. A plurality of recesses 12 and flanges 5 for containing eggs are formed, and a plurality of recesses 22 and flanges 5 for containing eggs, which are partitioned by the partition wall, are formed in the lid portion 2 as with the body portion 1, and An egg packaging container is known in which the partition wall and the protrusion are removed to form a flat labeling surface 24.

The flat label sticking surface 24 is
It is used to attach a bar code (POS mark) and a label 4 indicating the producer and quality.

When packaging chicken eggs, each recess of the body part 1
After the eggs are put in 12, the lid portion 2 is bent through the connecting portion 3, and the flange portion 5 facing the connecting portion 3 is stapled or heat-sealed to seal it.

[0005]

According to such a conventional egg packaging container having a flat labeling surface 24, when the egg packaging containers in which chicken eggs are packaged are stacked, the flat labeling surface 24 is present. As a result, the skid slips easily and the load is easily broken, and the eggs may be damaged during the distribution stage.

Therefore, the present invention was devised in order to obtain an egg packaging container that is unlikely to skid even when stacked.

[0007]

The egg packaging container of the present invention is a synthetic resin sheet egg packaging container in which an openable and closable body part 1 and a lid part 2 are connected by a foldable connection part 3. A plurality of recesses 12 partitioned by partition walls 11 are formed on the top surface of the lid portion 2, and a high peripheral portion 25 is formed on the top portion of the lid portion 2.
And a label attaching surface 24 composed of a low depression 26 surrounded by a peripheral portion 25 thereof.

The egg packaging container of the present invention is a synthetic resin sheet egg packaging container in which a body part 1 that can be opened and closed and a lid part 2 are connected by a foldable connecting part 3. A plurality of recesses 12 are formed by partitioning, and a high peripheral portion 25 and the peripheral portion are formed on the top of the lid portion 2.
The label attaching surface 24 is formed by an indented recess 26 that is inclined downward from 25 toward the center.

【Example】

(First Embodiment) As shown in the plan view of FIG. 1, a transparent or translucent thin synthetic resin sheet is vacuum-molded or blow-molded. The body part 1 has a partition wall 11 and a crossing part of the partition wall 11. A plurality of recesses 12 and flanges 5 for inserting eggs, which are partitioned by the protrusions 13 provided, are formed, and in the lid portion 2, the partition wall 21 and the protrusions provided at the intersections of the partition walls 21 as in the body portion 1. A plurality of recesses 22 and flanges 5 for containing eggs partitioned by the parts 23 are formed, and a label attaching surface 24 from which the partition 21 and the protruding part 23 in the middle are removed is formed, and the body part 1 and the lid part are formed. 2 is
It is formed integrally via a foldable connecting portion 3.

As shown in the longitudinal sectional view of FIG. 2 and the transverse sectional view of FIG. 3, the label attaching surface 24 formed on the top of the lid portion 2 is surrounded by a high peripheral portion 25 and the peripheral portion 25. It consists of a shallow recess 26.

(Second Embodiment) A longitudinal sectional view of FIG. 4 and FIG.
As shown in the cross-sectional view of FIG. 1, the label attaching surface 24 formed on the top of the lid portion 2 is composed of a high peripheral portion 25 and a recess 26 inclined from the peripheral portion 25 toward the central portion.

When packaging chicken eggs in the egg packaging container of each of the embodiments described above, after the eggs are placed in the recesses 12 of the body portion 1, the lid portion 2 is bent through the connecting portion 3,
The flange portion 5 facing the connecting portion 3 may be stapled or heat-sealed to seal it.

Egg packaging containers in which chicken eggs are packaged are stacked with the lid portion 2 having the labeling surface 24 facing upward, and the concave portion 12 of the body portion 1 projecting downward in the upper egg packaging container is placed in the lower egg. When placed on the labeling surface 24 of the packaging container, since the peripheral portion 25 of the labeling surface 24 is formed high and the central portion is formed low, gravity tends to concentrate in the center, so it does not skid and is stable. Can maintain a good posture.

The flat surface 27 formed on the side wall of the lid portion 2 shown in FIG. 1 is a surface for sticking a large label continuously to the label sticking surface 24 at the top, and is a horizontal surface when stacked. From the direction, the contents displayed on the label on the flat surface 27 of the side wall can be confirmed.

As an egg packaging container having a flat surface to which the present invention is applied, as shown in FIG. 6, a lid portion 2 has a projecting portion 23 serving as a partition, and the label 4 is provided around the projecting portion 23.
It can also be applied to an egg packaging container provided with a label sticking surface 24 for sticking.

[0016]

As is clear from the description based on the above embodiments, according to the egg packaging container of the present invention, even if the egg packaging container has a flat labeling surface for attaching a label, it slips sideways when stacked. Since the load does not collapse, it is possible to prevent the eggs from being damaged during the distribution stage.
