Description

  The present invention relates to a portable folding container that can be used for a shopping container or the like.

  In supermarkets and the like, in general, after putting a product in a cash register basket or cash register cart and paying it out at the cash register, the goods are transferred from the cash register basket or cash register cart to the resin bag that was picked up at the cash register. Recently, charging of resin bags has been promoted in consideration of the adverse effects of heavy use of resin bags on the environment. Many customers bring shopping containers in place of such resin bags.

  There are many cloth bags as shopping containers that customers bring. However, in the case of a cloth bag with a small amount of accommodation, a plurality of cloth bags must be prepared if the amount of goods is large. Further, in the case of a flexible cloth bag, as in the case of a resin bag, there is a possibility that the stored product may not be stable and may be tilted or out of shape, resulting in a decrease in product value. Therefore, although it is possible to bring the same kind of shopping basket and cash register basket having a large amount of storage and a certain degree of rigidity, there is a problem that the shopping basket becomes bulky when the shopping is reciprocated.

  Therefore, the present applicant provides a portable folding container disclosed in Patent Document 1 below.
