Abstract

A container includes a capitula to put contents into and out from the container, an inside container main body, in which a portion to accommodate the contents is formed, and an outside container main body, which is formed on an outer periphery side of the inside container main body, and surrounds the inside container main body. The inside container main body and the outside container main body are integrated at the capitula. A first side peripheral wall of the inside container main body and a second side peripheral wall of the outside container main body are attached to each other and are formed as a double accumulating portion at least at a portion of the first side peripheral wall. A lower end of the second side peripheral wall includes an extended foot portion that is extended to a location lower than a bottom of the inside container main body.

First claim

The invention claimed is:

1. A container comprising:
a neck portion having an opening to put contents into and out from the container;
an inside container main body, in which an accommodating portion that accommodates the contents is formed; and
an outside container main body, which is formed on an outer periphery side of the inside container main body, and surrounds the inside container main body, wherein
the inside container main body and the outside container main body are integrated at the neck portion,
a side peripheral wall of the inside container main body and a side peripheral wall of the outside container main body are in contact with each other and are formed as a first accumulating portion along an entire side peripheral wall of the inside container main body, and
a lower end of the side peripheral wall of the outside container main body includes an extended foot portion that is extended to a location lower than a bottom of the inside container main body.

2. The container as defined in claim 1 , wherein in the first accumulating portion, the side peripheral wall of the inside container main body and the side peripheral wall of the outside container main body are detachable.

3. The container as defined in claim 1 , wherein in the first accumulating portion, the side peripheral wall of the inside container main body and the side peripheral wall of the outside container main body are welded.

4. The container as defined in claim 1 , wherein a thickness of the side peripheral wall of the inside container main body is smaller than a thickness of the side peripheral wall of the outside container main body.

5. The container as defined in claim 1 , wherein
a cross section of the outside container main body is substantially perpendicular to the side peripheral wall of the outside container main body, and
a thickness of the side peripheral wall of the outside container main body gradually decreases along a direction from a first portion of a circumference of the cross section at the largest width of the cross section to a second portion of the circumference of the cross section at the smallest width of the cross section.

6. The container as defined in claim 1 , wherein
a cross section of the outside container main body is substantially perpendicular to the side peripheral wall of the outside container main body, and
a thickness of the side peripheral wall of the outside container main body gradually decreases along a direction from a third portion of a circumference of the cross section at the smallest width of the cross section to a fourth portion of the circumference of the cross section at the largest width of the cross section.

7. The container as defined in claim 5 , wherein the side peripheral wall of the outside container main body at the second portion is configured to be squeezed.

8. The container as defined in claim 6 , wherein the side peripheral wall of the outside container main body at the fourth portion is configured to be squeezed.

9. The container as defined in claim 1 , wherein
a first shoulder portion of the inside container main body extends from the neck portion to the side peripheral wall of the inside container main body, a second shoulder portion of the outside container main body extends from the neck portion to the side peripheral wall of the outside container main body, and the first shoulder portion and the second shoulder portion are in contact with each other and are formed as a second accumulating portion.
