In order to achieve the above object, the present invention takes the following technical measures. That is, in the present invention, the two storage recesses 1a, 1
a are formed as a set, a large number of egg storage recesses 1... are individually divided by vertical and horizontal partition walls 2, and are arranged and arranged in a plurality of rows such that the individual storage recesses 1 a. And a trapezoidal projection 3 formed at the intersection of the vertical and horizontal partitions 2 is formed of a synthetic resin sheet material, and the tray main body A is formed of each egg storage recess 1. .. Have sufficient strength to be able to be carried in a state where the eggs are stored therein, and have a length P1 that is half the pitch P of the storage recess 1a at two adjacent side edges of the tray body A. The extension spaces 4 and 4 are configured to be extra.

In the tray configured as described above,
As shown in FIGS. 3 to 5, when the upper tray body A is rotated upward by 180 ° with respect to the lower tray body A and stacked with the respective side edges aligned on a vertical line, the above-mentioned half pitch is obtained. Due to the extension spaces 4 and 4, the bottom surface of the storage recesses 1a of the upper tray comes into contact with the upper surface of the trapezoidal projections 3 of the lower tray, thereby eliminating the load on the eggs stored in the storage recesses and breaking the eggs. Can be prevented from occurring.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below based on an embodiment shown in the drawings. In the drawing, reference numeral A denotes a tray main body, which has a quadrangular shape in plan view, and has a large number of egg storage recesses 1... Formed as a set of two storage recesses 1a, 1a separated by a small partition 2 ′. Are arranged in a plurality of rows so as to be individually divided by the partition walls 2 and so that the individual storage recesses 1a have a constant pitch P. A trapezoidal projection 3 is formed at the intersection of the vertical and horizontal partitions 2, 2 and 2 '.

[0008] The tray body A is provided with each of the egg storage recesses 1 ...
It is formed of a synthetic resin sheet material in a state in which it has sufficient strength so that it can be carried in a state where eggs are stored. Further, at two adjacent side edges of the tray main body A, extension spaces 4 and 4 having a length P1 which is half the pitch P of the storage recesses 1a are formed. In the present embodiment, the recesses 5 are provided in the extension spaces 4 and 4. However, the recesses 5 may be eliminated and formed on a flat surface.

The egg storage tray constructed as described above is
Usually, as shown in FIG. 1, two egg containers C for two containing two boiled eggs are stored in the egg storage recess 1, and a large number of them are stacked.
