Title:
PACKAGING BAG FOR HEAT-INSULATING FOOD
Document Type and Number:
Japanese Patent JP3851705
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent food from being altered by cold insulator by making one of sections sectioned by a nonwoven cloth to be a food storage and the other to be a cold insulator storage.
SOLUTION: A span bond nonwoven cloth 3 comprising polypropylene fiber is put between two layers of polypropylene films 2, 2 as a waterproof sheet, and left and right side rims and a bottom rim are heat-fused to form a bag body 1. Food is put in one of sections 4 for packaging, while a mount 5 made of proofed cardboard is put in the other section. The mount 5 is formed with a standing piece 6 by providing a U-shaped cut approximately at the center, and cold insulator 7 inserted from an opening is locked with the standing piece 6. Then the opening of the bag 1 is conveniently folded or the like to complete food packaging. Thus since the food and the cold insulator are not in direct contact with each other, the food may not tightly stick to a surface of the cold insulator and also dews are not likely to be formed on the surface of the cold insulator.
