Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to an egg packaging container used for containing and transporting eggs.

[0002]

[Prior art]

 Pulp mold paper packaging material is made of waste paper and used as a packaging container (tray) in which a large number of square and rectangular recesses are arranged and used to store chicken eggs and used as a transportation container. ing.

[0003]

[Problems to be solved by the device]

 However, a packaging container having a plurality of recessed portions for accommodating the eggs is packaged in a large number, and when used, it is peeled off for each one and used. However, packaging containers with a large number of recesses are stacked and fitted, and the individual recesses are closely fitted, and it is very difficult for them to peel off. And it lacked adaptability and adaptability for mechanization.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above problems, and its gist is that a roller is formed by four pyramidal truncated cylinders arranged in a square shape and adjacent to each other are integrally formed with a bowl-shaped recess. In this way, a large number of trays are arranged in a matrix pattern in the vertical and horizontal directions, and a structure in which the lower end peripheral flange is provided is a tray that can stack a large number of pyramidal frustum cylinders and bowl-shaped recesses. By appropriately providing spacer protrusions on the upper surface of the lower end flange portion of each tray and / or the outer surface of the truncated pyramid cylinder portion, and when stacking the trays by fitting and stacking, each spacer is interposed by the spacer protrusions. The egg packaging container is characterized in that the trays are closely fitted to each other so that they can be easily peeled off individually. Next, the packaging container for chicken eggs of the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

[0005]

【Example】

 First, A is a tray which is a packaging container for chicken eggs of the present invention, and the tray A is constructed from waste paper as a raw material as follows. That is, four pyramidal truncated pyramid cylinders 1 arranged in a quadrangular shape are arranged adjacent to each other so as to form a bowl-shaped recess 2 inside, and a large number of them are arranged in a grid pattern in the vertical and horizontal directions. With the structure in which the parts 3 are provided, each of the truncated pyramid cylinders 1 and the bowl-shaped recesses 2 are fitted to each other so that a large number of sheets can be stacked.

In the present invention, however, when the tray protrusions 4 are appropriately provided on the upper surface of the lower end peripheral flange portion 3 of each tray A and / or the outer surface of the truncated pyramid cylinder portion, the tray A is stacked and fitted. By the interposition of the spacer protrusions 4, the close fitting between the stacking trays A, A is separated as shown in FIG. 5 so that each tray A can be easily peeled off individually.

[0007]

[Effect of the invention]

 According to the present invention, when a large number of trays A are fitted and stacked, the close fitting between the stacking trays A and A is automatically easily separated and easily peeled off due to the interposition of the spacer protrusions 4. Therefore, a large number of trays A that have been fitted and stacked and accumulated at a predetermined place can be accurately and easily moved and handled one by one by mechanical means such as vacuum suction, which is very useful.

Further, since it has a simple structure and is rational and rational, it has good workability, is efficient, and is economical.

Further, it is possible to easily deal with mechanization of work, which can significantly contribute to improvement of work efficiency and rationalization of work.
