Square bottle

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.

Synthetic resin bottle

A bottle is a bottle formed of synthetic resin materials in a cylindrical shape with a bottom. A bottom wall portion in a bottom portion thereof includes a grounding portion positioned at an outer circumferential edge thereof, a rising circumferential wall portion connected to the grounding portion from an inside of a bottle radial direction and extending upward, a movable wall portion protruding from an upper end part of the rising circumferential wall portion toward the inside of the bottle radial direction, and a recessed circumferential wall portion extending upward from an inner end part in the bottle radial direction of the movable wall portion. The movable wall portion is arranged to be movable upward together with the recessed circumferential wall portion, around a connected portion with the rising circumferential wall portion. A plurality of ribs are arranged in the movable wall portion radially around a bottle axis.

Cylindrical bottle with bottom

A bottomed cylindrical bottle formed of a synthetic resin material through biaxially oriented blow molding, includes a bottom portion of the bottle having a bottom wall portion, the bottom wall portion including a ground portion disposed at an outer circumferential edge portion, a rising circumferential wall portion continuously extending upward so as to be connected to the ground portion from an inside in a bottle radial direction, a movable wall portion protruding from an upper end portion of the rising circumferential wall portion toward the inside in the bottle radial direction, and a recessed circumferential wall portion having a diameter in the bottle radial direction such that the diameter gradually decreases in a direction from an inner end portion of the movable wall portion toward an upper side thereof, an annular recess depressed upward being formed at the movable wall portion in a circumferential direction thereof.

A tubular bottle is formed of a synthetic resin material having a bottom part. A bottom wall part of the bottom part includes a grounding part located at an outer circumferential edge thereof, a standing peripheral wall part which is connected from a radial inner side of the bottle to the grounding part and which extends upward, a movable wall part that protrudes, from an upper end of the standing peripheral wall part, toward the radial inner side, and a depression peripheral wall part that extends upward from an inner end of the movable wall part in a radial direction of the bottle. The movable wall part is arranged so as to be movable upward centering on a portion connected to the standing peripheral wall part. An upward swelling part is formed at an outer end along the radial direction of the bottle of the movable wall part.

A bottle including a bottom portion including a heel portion, and a bottom wall portion, wherein the bottom wall portion includes a rising circumferential wall portion continuing into the ground portion and extending upward, a movable wall portion having an annular shape and protruding toward the inside in the radial direction of the bottle, and a recessed circumferential wall portion extending upward from an inner edge portion of the movable wall portion in the radial direction of the bottle. The movable wall portion is freely rotatably provided having a connected portion with the rising circumferential wall portion as a center so as to move the recessed circumferential wall portion upward. A lower heel edge portion continuing into the grounding portion is formed in a smaller diameter than an upper heel portion continuing into the lower heel edge portion from an upper side.

Bottle made from synthetic resin material and formed in a cylindrical shape having a bottom portion

Provided is a bottle including a bottom part having a bottom wall part. The bottom wall part includes a grounding part located at the outer circumferential edge thereof, a standing peripheral wall part connecting to the grounding part from a radial inner side of the bottle and extending upward, an annular movable wall part projecting from an upper end of the standing peripheral wall part toward the radial inner side of the bottle, and a depression peripheral wall part extending upward from an inner end of the movable wall part in a radial direction of the bottle. The movable wall part is disposed to freely pivot around a connection part connected with the standing peripheral wall part so as to move the depression peripheral wall part in an upward direction, and the depression peripheral wall part is formed to have multiple stages.

The present invention relates to a bottle which is formed of a synthetic resin material into a cylindrical shape with a bottom. A bottom wall portion of a bottom of the bottle includes: a ground contact portion; a rising peripheral wall portion; a ring-shaped movable wall portion; and a depressed peripheral wall portion. The movable wall portion is rotatably disposed about a connecting part with the rising peripheral wall portion so as to move the depressed peripheral wall portion upward, and a concave and convex portion is formed over an entire circumference of the rising peripheral wall portion.

A synthetic resin bottle has a cylindrical shape with a bottom, and a bottom wall portion that includes a grounding portion located at an outer circumferential edge, a rising circumferential wall portion that is connected from an inner side to the grounding portion and extends upward, an annular movable wall portion protruding from an upper end of the rising circumferential wall portion toward the bottle radial inner side, and a recessed circumferential wall portion between the bottle radial inner side and the movable wall portion. The movable wall portion is free to rotate around a portion connected to the rising circumferential wall portion so as to move the recessed circumferential wall portion in an upward direction. The rising circumferential wall portion extends to be gradually inclined toward the bottle inner side, and an inclined angle thereof is equal to or less than 10&#xb0; with respect to a bottle axis.
