In a container, a first distance from an engagement upper end of a male thread of a mouth to a bead portion is larger than a second distance from an engagement lower end of a female thread of a cap to a resiliently deformable portion of a tamper evident band.

Container

A novel synthetic resin container includes an entirely or partly dome-like shoulder portion interconnecting a mouth portion and an upper end of a body portion, and provides high strength at the shoulder portion and excellent aesthetic appearance. The shoulder portion has a dome-like region with a plurality of rhombic and triangular bulging portions arranged in the circumferential direction, each protruding outward from its rhombic or triangular outer edge toward its inner edge. The plurality of triangular bulging portions are arranged between the rhombic portions. The rhombic inner edge defines a region protruding inward of the container and thereby forming a rhombic depression, which is provided with a rib having a vertical contour line that protrudes outward. The triangular inner edge defines a region protruding inward of the container so as to form a triangular depression, which is provided with a rib having a vertical contour line that protrudes outward.

Synthetic resin container

A synthetic resin bottle including a body having a bottom, wherein the body is divided by a waist into an upper body portion and a lower body portion. The bottle is easily portable and operable without requiring an additional handle, etc. and has high buckling strength. The bottle has a dome-shaped upper body portion connected, with the waist in between, to the lower body portion having the bottom, a shoulder surrounding the upper end of the upper body portion, and a tubular neck part connected to the shoulder. Two depressions facing each other are arranged on the rear side of the upper body portion along its circumferential direction. The portion formed between the depressions functions as a grip, and vertical ribs are each provided on a step surface formed on the front side of each depression.
