Abstract

A laminated bottle formed in a cylindrical shape with a bottom includes: an outer layer; and a flexible inner layer laminated onto an inner surface of the outer layer and being separable from the inner surface. A bottom section of the outer layer positioned at a bottle bottom portion is provided with a holding rib pinching and holding the inner layer. A part of the outer layer is provided with an intake hole allowing outside air to be imported into a space between the outer layer and the inner layer, and the holding rib is provided in each of a pair of areas which are disposed within the bottom section at an interval such that a bottle axis is interposed between the areas in a bottle radial direction.

First claim

What is claimed is:

1. A laminated bottle formed in a cylindrical shape with a bottom, the laminated bottle comprising:
an outer layer; and
a flexible inner layer in which contents are contained and which is configured to perform volume-reduction deformation in accordance with a decrease of the contents,
wherein the inner layer is laminated onto an inner surface of the outer layer and is separable from the inner surface,
a bottom section of the outer layer positioned at a bottle bottom portion is provided with a holding rib pinching and holding the inner layer,
a part of the outer layer is provided with an intake hole allowing outside air to be imported into a space between the outer layer and the inner layer, and
the holding rib is provided in each of a pair of areas which are disposed within the bottom section at an interval such that a bottle axis is interposed between the areas in a bottle radial direction,
a pair of holding ribs are provided on one straight line extending in the bottle radial direction, and extend along the straight line, and
the intake hole is provided in a part of the bottom section positioned between the pair of holding ribs, and extends along the straight line.

2. The laminated bottle according to claim 1 ,
wherein the bottle bottom portion includes:
a grounding portion positioned at an outer circumferential edge part of the bottle bottom portion, and
a recessed portion connected to the grounding portion from inside of the bottle in the bottle radial direction and positioned on an inner side of the bottle than the grounding portion, and

the holding ribs and the intake hole are formed in the recessed portion.
