In opening structure of the tray condition container packing body and the tray condition container packing body null bottom wall

摘要

PROBLEM TO BE SOLVED: To provide an unsealing structure of a tray-like container package by which a necessary part of a stored object, such as solid roux, is unsealed according to usage.;SOLUTION: The tray-like container package is composed of tray-like containers each of which has a storage compartment having a top opening, and a flange (5) extending from the top edge of the peripheral wall of the storage compartment, and lid members which are heat-sealed on the containers. The stored object is stored in the storage compartments of the tray-like containers, and then the top openings are heat-sealed with the lid members to form the unsealing structure of the lids of the tray-like container package. The heat-sealing strength between the flange (5) of each storage compartment and the inner surface of the lid (21) corresponding to the flange (5) is set greater than the heat sealing strength between the inner surface of each tab (22) and the outer surface of the lid (21) under the tab (22).;COPYRIGHT: (C)2006,JPO&NCIPI
