Description

[Detailed description of the invention] <Industrial application field> The invention is a resin molded product produced mainly by vacuum forming of resin film, and is suitable for handling multiple eggs even if they are roughly handled during the distribution stage. A container that can store and hold multiple eggs separated from each other to prevent damage caused by collisions between eggs. In order to make it possible for automatic machines such as registers to read codes such as bar codes that indicate required information such as size and manufacturer's name, the codes must be clearly marked on a flat surface rather than on an uneven surface. The present invention relates to an egg container having a flat surface formed on its outer wall for attaching the above-mentioned necessary information automatic reading number.

For more details, see Japanese Patent Application No. 57-188389 (Japanese Unexamined Patent Publication No. 59-84773), which was previously filed and published by the present applicant.
No. 47793 (Utility Application No. 47793, 1987), which was filed by the present applicant after that,
164180), it consists of a body part and a lid part that can be opened and closed, and in a plurality of places where these two parts face each other, egg holding spaces are formed when the two parts are in the closed position. The recesses are formed in each of the two parts so that a partition wall having a height lower than the peripheral edge of the body and the lid is located between the adjacent recesses, and at the meeting point of each partition, the above-mentioned recesses are formed. A columnar body is formed that contacts each other in the closed position of both parts, and on the outer wall of either the body or the lid, there is a space between two adjacent recesses on the outer periphery of the body or the lid. The present invention relates to an improvement in an egg container in which a flat surface for attaching a code for automatically reading required information is formed over the length of the egg container.

<Prior art> As shown in FIG.
Or recesses 0 adjacent to each other on the outer periphery of the body OA
1b, 01b or 01a, 01a, the flat surface 04 is formed to have a height equal to the depth of the recesses 01b, 01b, or the adjacent recesses 01b, 01b, or 01a .

<Problems to be solved by the invention> The flat surface of the egg container according to the earlier application has a sufficient area, and the code can be made larger accordingly, and a code with excellent readability can be added. On the other hand, there were the following drawbacks when packaging a large number of egg containers for distribution.

That is, this type of egg container stores and holds eggs, and the body and the lid are closed and fixed, and a large number of eggs are stacked vertically and protrude downward from the upper egg container. Each of the recesses is surrounded by a plurality of recess groups on the upper surface of the lower egg container to form an upwardly open recess;
On the other hand, on the lower surface of the upper egg container, the columnar part is surrounded by a plurality of recesses and forms a downwardly open recess, and each of Generally, the entire container is stacked with the entire container shifted by the distance between the adjacent recesses so that the recesses fit into each other, and the container is packed in a box and distributed for transportation and display. In such egg containers, since a recess into which the upper and lower egg containers fit as described above is not formed between the adjacent recesses where the flat surfaces are formed, when stacking three or more tiers, as shown in FIG. It is necessary to stack the upper egg containers one by one by shifting them in one direction. Therefore, when stacking multiple layers, a large amount of dead space is created inside the packaging box, resulting in an inefficient packaging form in which the actual number of containers is small to save the internal volume of the packaging box. Because the stacking is done in staggered tiers, the stacking posture becomes unstable compared to the number of stacked tiers, which naturally limits the number of stacked tiers, which is extremely disadvantageous in terms of space factors for packaging and display. It was hot.

<Means for solving the problem> In view of the above-mentioned circumstances, the present invention provides a space frame for stacking a large number of items in boxes while ensuring a flat surface of sufficient size necessary for reading the above-mentioned code. The object is to provide an egg container that is advantageous in terms of actors.

In order to achieve the above object, in the egg container according to the present invention, in the egg container described in detail at the beginning, the flat surface is formed by extending between the peripheral wall portions of the recessed portion, which is half the depth of the recessed portion, or approximately half the depth of the recessed portion. The structure is characterized in that the flat surface is formed with half the height.

<Function> The egg container according to the present invention having the above-mentioned configuration is provided with a required information automatic reading code on the flat surface, so that the flat surface can be read as a generally flat code on an automatic reading machine such as a register. By sliding it along the reading surface, it senses the magnetic symbols etc. emitted from the code and ensures automatic reading of the required information.
It can be done accurately.

Therefore, when a plurality of egg containers containing a predetermined number of eggs and whose bodies and lids are closed and fixed are stacked in a packaging box or stacked on a shelf for display and sale, the fourth As shown in Figures A and B, there are also recesses between the adjacent recesses where the flat surfaces are bridging, and the upper and lower egg containers are fitted together as described above by crossing these recesses. By stacking them in a formula, a stable multi-tiered stacking posture can be obtained, and stacking can be done with less protrusion in terms of space.
