も薄肉に製造される。These synthetic resin containers are mainly manufactured by blow molding, and the pouring portion is required to have sufficient rigidity for mechanical suitability for filling contents, suitability for capping, etc. Independent stability and strength that can withstand a drop impact are required. On the other hand, the body has quality characteristics that require storage and discharge of contents, strength against pressure reduction after filling contents, buckling strength for loading, etc. Manufactured to be thin.

さくなりにくく嵩張るため、輸送、保管に不便である。However, even if the container made of synthetic resin is crushed at the time of waste collection after consumption of the contents, the elasticity of the synthetic resin restores it to its original state, and it is difficult to fold or compress and the volume is difficult to be small and bulky. Inconvenient for transportation and storage.

状態を保持することができるので、元の状態に復元せず
にコンパクトな状態で廃棄することができ、廃棄容器の
保管スペースを少なくできる。EFFECTS OF THE INVENTION When the container of the present invention is discarded after the contents are consumed, it can be easily folded into small pieces by folding along the bent portion formed on the container, and the folded state can be maintained. Therefore, it can be discarded in a compact state without being restored to the original state, and the storage space of the waste container can be reduced.
【００３６】また、折り畳み段階で胴部に生じた空隙を
利用して折り畳み状態を保持するので特別な保持部材が
不要であり、製造が容易で、かつ、原料の使用量が少な
く済み、コストを抑えることが可能である。In addition, since the folded state is held by utilizing the voids formed in the body portion during the folding step, no special holding member is required, the manufacturing is easy, the amount of raw materials used is small, and the cost is low. It is possible to suppress.
