    • PROBLEM TO BE SOLVED: To provide a bottom structure which does not cave in under condition that the inner pressure of a synthetic resin container becomes extremely large, and has high strength against dropping. SOLUTION: According to the bottom structure of the synthetic resin container, the lower end of the trunk part 14 of a PET bottle 10 is expanded downward along the trunk axial line O to form curved walls 2, which are then expanded intermittently in the peripheral direction to form a plurality of leg parts 4 surrounding the center of the curved walls 2, which is an upper bottom wall 3. The outer wall 5 of each leg part 4 forms a curved portion between the upper end c and the lower end e of the outer wall 5, the curved portion having a radius of curvature R4 of 1.5 times or more as large as the axial height L5 of the outer wall 5. An effective diameter ψ1 at the lower end e is 92% or less of an effective diameter at the upper end ψ2. The curved wall 2 connecting each side wall 6 of each leg part 4 forms such a valley bottom that the end width W1 closer to the trunk part of the leg part 4 is 1.2 times or more the end width W2 closer to the upper bottom wall 3 of the leg part 4, in which upper bottom wall 3 has a degree of crystallization of 30% or less.

    • PROBLEM TO BE SOLVED: To create a side peripheral wall structure of a synthetic-resin square bottle, that can effectively obtain restorability which decreases due to the reduced thickness of the bottle, especially when the side peripheral wall is deformed so as to be bent by a load applied from a lateral direction. SOLUTION: The synthetic-resin square bottle includes a body where the side peripheral wall is formed by four flat side walls and four chamfered corner walls coupling the side walls. A vertical-groove-like vertical rib is arranged along an edged line formed in a border of the side wall and the corner wall. Further, in an area of the vertical rib at a predetermined height, a plurality of vertical-groove-like vertical auxiliary ribs are arranged along the vertical rib so that they laterally align.

    • PROBLEM TO BE SOLVED: To provide a synthetic resin square bottle which prevents the formation of a projecting portion due to depressurization-absorbing deformation to safely maintain a fine appearance without causing the breakage of a shrink label. SOLUTION: The synthetic resin square bottle 1 with a depressurization-absorbing function has an oblong and cylindrical trunk 4, at least the upside of which is covered with the shrink label 14. A boundary corner 12 on the top of a long side wall 6 of the trunk 4 is located inwardly to the extend that the boundary corner 12 does not project outside the long side wall 6 when the part of the long side wall 6 near a waist 5 deforms to cave in due to depressurization absorption. This prevents the breakage of the shrink label 14 attached to the trunk 4 and a deterioration in the appearance caused by depressurization-absorbing deformation. COPYRIGHT: (C)2008,JPO&INPIT
