METHOD FOR MANUFACTURING CONTAINER AND METHOD FOR SEPARATING INNER LAYER
First Claim
1. A method for manufacturing a container comprising a casing configured to contain a content, the casing including an inner layer having an inner layer opening for supplying the content to an outside and an outer layer covering the inner layer and having an air communication port communicating between a space between the outer layer and the inner layer and the outside, the method comprising the steps of:
- preparing a casing in which at least part of the inner layer and at least part of the outer layer are in contact with each other;
inserting a support column inside the inner layer through the inner layer opening of the prepared casing; and
after the insertion step, separating the inner layer from the outer layer by supplying air into the space through the air communication port to bring part of the separated inner layer into contact with the support column,wherein the support column includes a columnar portion and an extending portion extending from the columnar portion in a direction intersecting a longitudinal direction of the columnar portion.

Abstract
Provided is a method for manufacturing a container including a casing configured to contain a content, the casing including an inner layer having an inner layer opening and an outer layer having an air communication port communicating between a space between the outer layer and the inner layer and the outside. The method includes preparing a casing in which at least part of the inner layer and at least part of the outer layer are in contact with each other, inserting a support column inside the inner layer through the inner layer opening of the prepared casing, and separating the inner layer from the outer layer by supplying air into the space through the air communication port to bring part of the separated inner layer into contact with the support column. The support column includes a columnar portion and an extending portion extending from the columnar portion.

20. A method for separating an inner layer of a casing from an outer layer of the casing, the casing being configured to contain a content and including an inner layer having an inner layer opening for supplying the content to an outside and an outer layer covering the inner layer and having an air communication port communicating between a space between the outer layer and the inner layer and the outside, the method comprising the steps of:
-
preparing a casing in which at least part of the inner layer and at least part of the outer layer are in contact with each other; inserting a support column inside the inner layer through the inner layer opening of the prepared casing; and after the insertion step, separating the inner layer from the outer layer by supplying air into the space through the air communication port to bring part of the separated inner layer into contact with the support column, wherein the support column includes a columnar portion and an extending portion extending outward from the columnar portion.
