とができる。When the egg is put into all the recesses 11 of the main body 10, the lid 20 is folded and closed by the gusset part 30, and the seal part 14 of the main body 10 and the seal part 24 of the lid 20 are closed. Are adhered by ultrasonic waves or the like. At this time, since the main body 10 and the lid 20 can be bent at the perforations 31 on both sides of the gusset 30, the bending is also easy. Even when an egg having a large egg length is put in the concave portion 11, when the lid 20 is closed, the egg is not covered with the lid 20.
When it comes into contact with the side wall of the concave portion 21, the bulging portion 19 is deformed to cause a small displacement on the lower side (see FIG. 8B), so that an egg with a large egg length can be wrapped without fear of breakage. In particular, since the lid body 20 is configured by alternately arranging the curved surface and the flat surface of the side wall of the concave portion 21 so that only the curved surface can be applied to the upper part of the egg, the egg having a large egg length can be properly maintained. Packaged in. Furthermore, in this egg pack, since the loose convex part 23 and the loose receiving part 13 are loosely joined together when the main body 10 and the lid 20 are in the closed state, displacement and bending can be suppressed. .

Also, during transportation, the egg pack has a large rigidity as a whole, so that the eggs can be reliably protected. In addition, since the large ventilation holes A are formed on both sides by the step bottom surfaces 15, 25, the egg packs are stacked. Can reliably maintain air permeability. In particular, the ventilation port A is formed at the edge portion having greater rigidity by the uneven patterns 17 and 27, and the abutment convex portions 12 and 22 and the seal portions 14 and 24 having a height corresponding to the band-shaped gusset portion 30 are formed. Since it is formed by the determination bottom surfaces 15 and 25 in a contact state, the opening area is securely held. The pack can be opened by tearing from one side using the perforations 31 provided in the gusset part 30.

になるという効果が得られる。As described above, according to the egg pack of the present invention, the egg containing portion of the main body and the egg containing portion of the lid forming the egg containing space are each formed into a substantially octagonal truncated pyramid shape. In addition, since the partition wall portion, the play convex portion, the play receiving portion, and the like are formed using a plane that is linked to the octagonal pyramid-shaped surface of these egg storage portions, the overall rigidity can be increased and the thickness can be reduced. In addition, since the egg support that receives the bottom of the egg is formed on the bottom of the concave part of the main body, even eggs with a large egg length can be securely protected and packaged,
Furthermore, since the concave groove for preventing overlap is formed at the upper part of the partition wall portion, it is possible to obtain the effect that even when the automatic packer is stacked and supplied, the close contact can be prevented and the sheet can be taken out one by one.
