Abstract
A container (1) including an opening part (2), a shoulder part (3), a barrel part (4), and a bottom part (5), wherein: the shoulder part (3) includes a hem part (30) in which the longitudinal section is curved in a convex arcuate shape toward the outside of the container and which is connected to the barrel part (4); and a plurality of groove parts (31) extending radially from the container-center side toward the outer-peripheral-edge side are formed in the shoulder part (3) so as to extend at least to a position that reaches an upper end edge (UE30) of the hem part (30).
Claims15
A synthetic resin container, comprising
- an opening part, a shoulder part, a barrel part and a bottom part,
- wherein:
- the shoulder part includes a hem part on a lower end side;
- the hem part is curved in a convex arcuate shape toward an outside of the container in a longitudinal section, and is connected to the barrel part;
- the shoulder part is formed in a truncated cone shape and is continued to the hem part while being diameter-expanded, and a position from which a longitudinal section of the shoulder part starts to be curved with the curvature radius of the convex arcuate shaped longitudinal section of the hem part is taken as an upper end edge of the hem part;
- a plurality of groove parts extending radially from a container-center side toward an outer-peripheral-edge side are formed in the shoulder part;
- and
- a terminating end of each groove part of the plurality of groove parts is located in a position projected over the upper end edge of the hem part, and is located in a range without passing over an outer-peripheral edge of the hem part.
