    • PURPOSE: To enable the reclosure by a mechanical means by holding stacked trays in an approximately perpendicular manner where a cover is formed so as to be connected to a lip in a sealed manner, and an upper surface is provided so as to receive the surface corresponding to the lower side of a bottom part of the tray. CONSTITUTION: A tray 10 and a cover 12 are pivot-connected by a hinge 14, and a corner 18 in the tray 10 is extended between a flat bottom part 16 and an upwardly erected flat side wall 20. A shelf 28 is provided on four corners of the tray, and loaded on an upper surface of a flange 30 to demarcate an upper part 26 of an opening when the trays are stacked. A lip 34 of the cover 24 is projected downward of the flange 30, and a pair of inwardly projecting ridges 42 are formed on each lip 34 of two corners most distant from the hinge 14 in order to fix a package at the closed position. Immediately before a flat surface 32 is lowered to a surface of the flange 30, a deviated outer end of the flange 30 slides through the ridge 42, and is fitted into a space 43.
