Description

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 body portion into which a thin synthetic resin sheet is vacuum-molded or blow-molded and a lid portion are integrally connected via a flexible connecting portion. Even after sealing, a flat surface on which dates such as a packaging date and a shelf life can be printed is formed.

[0002]

2. Description of the Related Art As shown in a perspective view of FIG. 5, a conventional egg container 10 comprises a body part 1, a lid part 2, and a connecting part 3 for connecting these two parts flexibly. The resin sheet is formed integrally by vacuum molding or blow molding, and the body part 1 and the lid part 2 are provided with partitions 11, 21
A plurality of concave portions 12 and 22 and a flange portion 5 and 6 for receiving the eggs separated by the above-mentioned method are provided.

[0003] After the eggs are put in the respective concave portions 12 of the body portion 1, the lid portion 2 is bent through the connecting portion 3, and the flange portions 5 and 6 opposed to the connecting portion 3 are stapled or heat-sealed. And sealed.

[0004] When packaging eggs using such a conventional egg container, small pieces of paper indicating the producer, packing date, expiration date, quality, etc. are enclosed together with the eggs, or a flat sheet formed in the egg container is used. What's more, labels that show the producer, packaging date, best-before date, quality, etc. were affixed.

[0005] In the food distribution industry, the "packing date" printed on the enclosed piece of paper or label must match the day of packaging, and the "packing date" is printed in advance before the day of packaging. It is strictly prohibited.

[0006]

However, since the laid eggs are shipped through various processes such as washing, sorting, and packaging, they cannot always be shipped as scheduled. It is extremely difficult to match the "real packaging date" with the "real packaging date".

Therefore, the present invention has been conceived to solve the problem of the date management printed on a piece of paper or a label.

[0008]

The egg container of the present invention is a synthetic resin sheet egg container in which an openable and closable body portion and a lid portion are connected by a bendable connecting portion. A plurality of partitioned recesses are formed,
A flat surface on which a date is printed is formed on a side in the longitudinal direction of the lid portion or the body portion.

Further, in the synthetic resin sheet egg container in which the openable and closable body portion and the lid portion are connected by a foldable connecting portion, the body portion has a plurality of recesses partitioned by partition walls. A flat surface for printing the date may be formed on the top surface of the lid portion.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) As shown in an open plan view of FIG. 1 and a sealed perspective view of FIG. 2, a thin synthetic resin sheet was vacuum-molded or blow-molded to separate a plurality of eggs from each other. In order to hold the egg in a closed state, the body part 1 and the lid part 2 are integrally formed via a foldable connecting part 3 so as to form an egg holding space.
The body portion 1 and the lid portion 2 are provided with concave portions 12 and 22 for accommodating a plurality of eggs separated by partition walls 11 and 21 and peripheral flange portions 5 and 6.

Further, a plurality of recesses formed in the lid portion 2
A continuous elongated flat surface 7 is formed on the 12 side walls. This elongated flat surface 7 is a flat surface for printing the date packaged by the ink jet printer, and
Or the flange portion 6 facing the connecting portion 3
Provide along. Alternatively, two portions may be provided along the connecting portion 3 and the flange portion 6.

If the elongated flat surface 7 is formed so as to be positioned at the same height in the sealed state regardless of the size (L, M, S) of the egg to be packaged, an ink jet printer Can be printed on various egg containers with the head fixed at a certain height.

When wrapping eggs in the egg container constructed as described above, after placing the eggs in the recesses 12 of the body part 1, a small piece of paper on which the producer and the quality, etc. excluding the date are printed is put together with the eggs. The lid portion 2 is folded through the connecting portion 3 and the flange portions 5 and 6 facing the connecting portion 3 are stapled or heat-sealed to seal.

Then, an ink jet printer for printing a date is installed along the belt conveyor, and is passed through the belt conveyor on the day of packaging, so that the ink jet printer is placed on the elongated flat surface 7 of the sealed egg container. The date of packaging can be printed.

The elongated flat surface 7 for printing the date is not limited to the lid portion 2 but may be provided on the body portion 1.

FIGS. 1 and 2 show an elongated flat surface 7
Although shown as being formed on a part of the side of the egg container, it may be formed over the entire length.

(Second Embodiment) As shown in the plan view of FIG. 3 and the perspective view of FIG. 4, a state in which a plurality of eggs are separated from each other by vacuum molding or blow molding a thin synthetic resin sheet. Foldable connecting part 3 so as to be held by
The body portion 1 includes a body portion 1 and a lid portion 2 which are integrally formed through a recess, and the body portion 1 has a concave portion for accommodating a plurality of eggs partitioned by a partition wall 11 so as to form an egg holding space in a closed state. The lid portion 2 is provided with protrusions 23 and 24 for separating the frustoconical or truncated pyramid-shaped eggs at a position facing the intersection 13 of the partition wall 11 of the body portion 1. 23 and 24 have a flat surface 26 around them.

The projections 24 at both ends have a shape obtained by cutting a truncated cone or a truncated pyramid in the vertical direction.
Are arranged to face outward. This cut surface 25
It is formed so that adjacent eggs can be kept apart from each other without collision.

As shown in FIG. 4, the flat surface 26 of the lid portion 2
Label 4 attached at the position indicated by the dotted line 42 in FIG.
Indicates the producer and quality by printing on paper, synthetic resin film, etc., and the shape is the flat surface of the lid 2.
The width is larger than the diameter of the base of the protruding portions 23 and 24, and the length is larger than the interval between the two cut sections 25. When the label 4 having such a size and shape is attached, the label 4 can maintain a flat posture.

Further, a continuous elongated flat surface 7 is formed on the side wall having the reinforcing rib of the lid portion 2. The elongated flat surface 7 is a plane for printing a date by an ink jet printer, and is provided along the connecting portion 3 or along the flange portion 6 facing the connecting portion 3. Alternatively, as shown in FIG. 3, two portions may be provided along the connecting portion 3 and the flange portion 6.

In the same manner as in the first embodiment, an egg is put in each concave portion 12 of the body portion 1, and a label 4 on which the producer, excluding the date, quality, and the like are printed is affixed. The lid portion 2 is folded, and the flange portions 5 and 6 facing the connecting portion 3 are stapled or sealed by heat fusion.

Then, the date packaged by the ink jet printer is printed on the elongated flat surface 7 of the sealed egg container by the ink jet printer.

(Third Embodiment) The egg container has the same configuration as that of the second embodiment. Flat surface of lid part 2
Blank 41 for printing the date on a part of the label 4 attached to 26
The date may be printed in the blank 41 of the label 4 by an ink jet printer after sealing.

Alternatively, the flat surface 26 of the lid portion 2 after sealing
Alternatively, the date may be directly printed by an ink jet printer.

[0025]

As is clear from the description based on the above embodiments, according to the egg container of the present invention, the packing date can be printed after the eggs are put in and sealed, so that it is possible to prevent the date printing of the pre-applied date. it can.
