## Abstract

A synthetic resin bottle prevents a trunk from undergoing unsightly deformation in response to reduced pressure inside the bottle and also increases flexibility in terms of container design and secures a label attachment area sufficiently. A synthetic resin bottle includes a mouth, a trunk, and a bottom, with a reduced pressure absorbing region configured to be displaced toward the inside of the bottle in response to reduced pressure inside the bottle. The trunk includes a cylindrical-shaped straight region, which has a length of not less than 100 mm in an axis direction extending along a center axis of the trunk and in which no irregularities are provided. The straight region has a weight of not less than 11 times a weight of the reduced pressure absorbing region.

## Claims

### Claim 1

A synthetic resin bottle including: a mouth through which a content medium is dispensed; a trunk contiguous with and below the mouth; and a bottom that is contiguous with and below the trunk and that is provided with a reduced pressure absorbing region configured to be displaced toward an inside of the bottle in response to reduced pressure inside the bottle, wherein
the trunk includes a cylindrical-shaped straight region which has a length of not less than 100 mm in an axis direction extending along a center axis of the trunk and in which no irregularities are provided, and
the straight region has a weight of not less than 11 times a weight of the reduced pressure absorbing region.

### Claim 2 (depends on 1)

The synthetic resin bottle of claim 1, wherein the weight of the straight region is not less than 12 times and not more than 15 times the weight of the reduced pressure absorbing region.

### Claim 3 (depends on 1)

The synthetic resin bottle of claim 1, including content medium container space having a capacity of not less than 500 ml and not more than 800 ml.
