Foldable heat insulating container and distribution method

Abstract

Provided is a frozen commodity distribution method reduced in labor and cost while holding the quality of frozen commodities and a cold insulation container unfoldable and foldable in a short time while providing high cold insulation performance. In the distribution method, the frozen commodities requiring cold insulation are stored in the cold insulation container formed of a vacuum thermal insulation material, and the cold insulation container is distributed by a refrigerator car, cold insulation car, or a room temperature car other than a chill car. In the foldable cold insulation container, each of peripheral wall parts, cover parts, and bottom face parts is formed by including the vacuum thermal insulation material in a sheet material, and the peripheral wall parts of the cover parts adjacent to the continuously arranged peripheral wall parts are foldable since the vacuum thermal insulation material is divided along pleat lines. When the container is used, the cover parts and the bottom face parts are rotated in closed attitudes to form into a box. When the container is not used, the bottom face parts are bent to the inside or outside of the peripheral wall parts, the cover parts are bent in the reverse direction of the bottom face parts, and the peripheral wall parts are allowed to approach each other while bending the peripheral wall parts inward along the pleat lines, stacked on each other, and folded.

Description

technical field [0001] The present invention relates to a delivery method of frozen products, and mainly relates to a small-lot delivery method for delivering frozen products from a wholesaler or the like to a plurality of markets or the like. [0002] The present invention mainly relates to a container for cold storage, a foldable cold storage container that can be folded when not in use. Background technique [0003] In recent years, with the popularization of frozen foods and the like, the delivery of frozen products that need to be kept cold has increased. Such delivery is generally divided into large-volume delivery from frozen product factories to wholesalers (distribution centers), etc., and small-lot delivery from wholesalers to supermarkets, small convenience stores, and the like. [0004] However, small-volume delivery of frozen products from wholesalers to supermarkets and small convenience stores is performed by distributing frozen products for each delivery loc...

Problems solved by technology

However, as mentioned above, the cold storage container 100 disclosed in JP-A-2003-112786 needs a lot of work when it is folded, and it must be placed intact without being folded, and the effect of folding cannot be brought into play.
