Abstract

A container including: an inner container having a nozzle portion that discharges loaded content; an outer container that is tubular, is formed of a hard resin, contains the inner container, and has an outer peripheral wall in which an opening portion is formed; a pressing portion formed of an elastomer, provided at the outer peripheral wall, and covering the opening portion; and a cap that is attachable to and removable from the outer container, and that covers the nozzle portion that projects out from the outer container.

First claim

The invention claimed is:

1 . A container, comprising:
an inner container having a nozzle portion that discharges loaded content; an outer container that is tubular, is formed of a hard resin, contains the inner container, and has an outer peripheral wall in which an opening portion is formed; a pair of pressing portions formed of an elastomer, provided at the outer peripheral wall, and covering the opening portion; a connecting portion that is made of an elastomer and integrally connects the pair of pressing portions and is wound in a peripheral direction on the outer peripheral wall of the outer container; a cap that is attachable to and removable from the outer container, and that covers the nozzle portion that projects out from the outer container; a base including an outer tube portion attached at an end portion of the outer container at an opposite side from the cap, the base including an inner tube portion disposed radially within the outer tube portion; and a drying agent contained within the inner tube portion of the base, wherein the outer peripheral wall of the outer container tapers from a base end of the outer container to a cap end of the outer container, wherein an air gap is defined between the inner container and outer container and between the inner tube portion and the outer tube portion, and wherein the drying agent is configured to absorb moisture that is contained in the air gap.

2 . The container of claim 1 , wherein a pair of the opening portions covered by the pressing portions are provided so as to have axial symmetry with respect to a central axis of the outer container.

3 . The container of claim 1 , further comprising an extending portion that is made of an elastomer and extends from the connecting portion toward the base of the outer container.

4 . The container of claim 1 , wherein a plurality of ribs are formed at an outer peripheral portion of the cap.

5 . The container of claim 1 , wherein the content is an adhesive.

6 . The container of claim 5 , wherein the inner container is made of polyolefin.

7 . The container of claim 6 , wherein the cap is made of polyolefin.

8 . The container of claim 1 , wherein the pressing portion has a bulging portion that bulges out further than the outer peripheral wall of the outer container, and wherein a concave portion is formed at the central portion of the surface of the bulging portion.

9 . The container of claim 8 , wherein a maximum thickness of the bulging portion is within a range of from 0.2 mm to 1.0 mm.

10 . The container of claim 1 , wherein a hardness A of the elastomer is within a range of from 40 to less than 80.

11 . The container of claim 1 , wherein water vapor permeability at a sample of a thickness of 0.5 mm of the elastomer, as measured in accordance with JIS Z 0208, is less than 2.0 g/m 2 ·24 h.

12 . The container of claim 1 , wherein oxygen permeability of the elastomer, as measured in accordance with JIS K 7126, is less than 1.0×10 −15 mol·m/Pa·s·m 2 .
