スクイズボトルおよび二重容器

Abstract

To suppress a pressing force required when discharging a small amount of a remaining content while ensuring a restoration performance of a constricted part.SOLUTION: A peripheral wall part of a trunk part is provided with a constriction part that extends radially inward as it approaches each other from both sides along a bottle axis O direction and is formed to be elastically deformable, the deepest part of the constriction part, which is located in an innermost radial direction is located below the central part in the bottle axis direction in a first part of a squeeze bottle 11, which is constituted by a shoulder part and the trunk part, an upper constriction part located above the deepest part among the constriction parts is provided across the central part of the first part in the bottle axial direction, the size of the upper constriction part in the bottle axial direction is larger than the size of a lower constriction part, which is located below the deepest part of the constriction part, the upper constriction part is formed into a curved surface shape that protrudes radially outward when viewed in a vertical cross section along the bottle axial direction.SELECTED DRAWING: Figure 1
