Abstract

(57) [Summary] (Correction) [Purpose] The purpose is to eliminate the difficulty in packaging and transporting large-sized storage containers, and to make it possible to reduce the size and package and transport it. [Structure] A thin wall portion having a recessed groove 15 is formed in the height intermediate portion of the three wall plates 3 and 4 of the box body 1 and the left and right side plates 13 of the cover frame body 11 and is configured to be folded inward. The top plate 12 of the cover frame 11 is integrally formed with the left and right side plates 13. This is a synthetic resin molding method in which a synthetic resin material forming a thin portion in a part of a large container causes shearing heat generation and re-plasticization when the thin portion is formed and flows through.

First of all, since all the members constituting the storage container can be folded and packed in a small size, the transportation becomes very convenient and the cost can be reduced.

Secondly, there is no inconvenience since the whole storage container can be assembled easily and quickly by the user.

Thirdly, when a plurality of storage containers with wheels are stacked and displayed or used, the storage containers can be always fixed in the upper and lower stages in a stable state, and the space for arranging the containers can be reduced. You don't have to.

Fourth, when disposing of the product when not in use,
The extracted box body and the covering frame body can be easily cut and disassembled from the concave groove of the thin portion.

Fifth, even for a large-sized molded article such as an extraction box or cover frame which constitutes a storage container, which is relatively thin and has a long synthetic resin material flow length, it can be folded. Since the thin part is formed in the middle part of the plate material, the protruding part of the mold can be reheated by the friction heat generated when the synthetic resin material flows through, so the synthetic resin material is replasticized and the fluidity is improved. Thus, even in the molding of a large-sized container, the entire synthetic resin material can be reliably molded to a predetermined material thickness up to the end without causing mid-way cooling.
