## Abstract

A synthetic resin container, including a mouth portion, a shoulder portion, a body portion and a bottom portion. The body portion is formed into an angular cylindrical shape and has one or more concave groove portions formed along a circumferential direction such that: a cross section shape of a site in which the concave groove portion is formed is similar to a cross section shape of a site formed into the body portion, and when the cross section shape of the site in which the concave groove portion is formed and the cross section shape of the site formed into the angular cylindrical shape of the body portion are superimposed, respective apexes of the cross section shape of the site in which the concave groove portion is formed internally contact respective sides of the cross section shape of the site formed into the angular cylindrical shape of the body portion.

## Claims

### Claim 1

A synthetic resin container, comprising a mouth portion, a shoulder portion, a body portion and a bottom portion, wherein
the body portion is formed into an angular cylindrical shape having a polygonal cross section shape and has at least one concave groove portion formed along a circumferential direction; and
the at least one concave groove portion being formed in such a manner that:
a cross section shape of a site in which the at least one concave groove portion is formed is similar to a cross section shape of a site formed into the angular cylindrical shape of the body portion, and
when the cross section shape of the site in which the at least one concave groove portion is formed and the cross section shape of the site formed into the angular cylindrical shape of the body portion are superimposed on each other on the same plane, respective apexes of the cross section shape of the site in which the at least one concave groove portion is formed internally contact with respective sides of the cross section shape of the site formed into the angular cylindrical shape of the body portion.

### Claim 2 (depends on 1)

The synthetic resin container according to claim 1, wherein the apexes of the at least one concave groove portion are located at the centers in the lateral width directions of the side faces of the body portion.

### Claim 3 (depends on 1)

The synthetic resin container according to claim 1, wherein the at least one concave groove portion is formed in such a manner that the respective sides of the cross section shape of the site in which the at least one concave groove portion is formed are linear or arched to protrude outward from the container.

### Claim 4 (depends on 1)

The synthetic resin container according to claim 1, wherein the apexes of the at least one concave groove portion include surfaces flush with the side faces of the body portion.

### Claim 5 (depends on 1)

The synthetic resin container according to claim 1, wherein the apexes of the at least one concave groove portion are chamfered to be in an R-chamfered state, a linear state, or a C-chamfered state.

### Claim 6 (depends on 1)

The synthetic resin container according to claim 1, wherein the body portion is formed into an angular cylindrical shape whose cross section shape is n-polygonal, where n is 3 to 12.
