Among the partitions divided by the turn line, at least one partition is at least the hard shell of the bottle body part which has a substantially higher overall rigidity. The other section is a reversing part having at least a relatively low overall rigidity of the bottle body portion and capable of elastically inverting the deformation, and the mouth tube portion is vertically disposed at the shoulder portion, and can be easily collapsed into the hard shell portion. The entire inverting portion can be restored to its original shape, and thus can be easily and fully reduced in volume and deformed into a flat shape. But also to restore the prototype. Sovereignty item 1. A bottle made of synthetic resin, forming at least one turning line (5) in the longitudinal direction at the shoulder (2), the body (3) and the bottom (4) of the bottle body (1). Among the sections divided by the flap line (5), at least one of the sections is at least a rigid part (8) of a substantially entire part of the body part (3), and the other section is at least a bottle part (3). A portion of the inverting portion (10) having a substantially lower overall rigidity and being capable of elastically inverting deformation, and the mouth tube portion (11) is vertically disposed in the fore-mentioned portion of the shoulder portion (2) so that the inverting portion (10) can be easily trapped. The inside of the hard shell portion (8) is deformed and can be restored to its original shape.
