Abstract

A container having: a bag body including an internal space to accommodate a content; an opening formed in the bag body and communicating the internal space to an outside of the container; and a fastener to open and close the opening, wherein the fastener includes a high engaging-strength portion and a low engaging-strength portion, the engaging strength of the low engaging-strength portion is less than the engaging strength of the high engaging-strength portion, the fastener includes a female track and a male track, and the low engaging-strength portion is a part of the fastener in which at least one of the female track and the male track is collapsed.

First claim

What is claimed is:

1. A container comprising:
a bag body including an internal space to accommodate a content;
an opening formed in the bag body and communicating the internal space to an outside of the container; and
a fastener to open and close the opening,
wherein the fastener includes a high engaging-strength portion and a low engaging-strength portion,
the engaging strength of the low engaging-strength portion is less than the engaging strength of the high engaging-strength portion,
the high engaging-strength portion includes a female track and a male track that are configured to engage with each other to close the opening,
the low engaging-strength portion includes a collapsed female track and a collapsed male track,
the collapsed male track includes a male track base on the bag body and a deformed male base that protrudes from the male track base toward the collapsed female track,
the collapsed female track includes a female track base on the bag body and a deformed female base that protrudes from the female track base toward the collapsed male track, and
the collapsed female track and the collapsed male track are configured to close the opening by contacting each other and to open the opening by being separated from each other when a pressure of the internal space rises due to vapor generated from the content accommodated in the internal space.

2. A content sealing container comprising:
the container according to claim 1 ; and
a content accommodated in the internal space,
wherein the opening is sealed.

3. A container comprising:
a bag body including an internal space to accommodate a content;
an opening formed in the bag body and communicating the internal space to an outside of the container; and
a fastener to open and close the opening,
wherein the fastener includes a high engaging-strength portion and a low engaging-strength portion,
the engaging strength of the low engaging-strength portion is less than the engaging strength of the high engaging-strength portion,
the high engaging-strength portion includes a female track and a male track that are configured to engage with each other to close the opening,
the low engaging-strength portion includes a female track and a collapsed male track,
the collapsed male track includes a male track base on the bag body and a deformed male base that protrudes from the male track base toward the female track of the low engaging-strength portion, and
the female track of the low engaging-strength portion and the collapsed male track are configured to close the opening by contacting each other and to open the opening by being separated from each other when a pressure of the internal space rises due to vapor generated from the content accommodated in the internal space.

4. A content sealing container comprising:
the container according to claim 3 ; and
a content accommodated in the internal space,
wherein the opening is sealed.

5. A container comprising:
a bag body including an internal space to accommodate a content;
an opening formed in the bag body and communicating the internal space to an outside of the container; and
a fastener to open and close the opening,
wherein the fastener includes a high engaging-strength portion and a low engaging-strength portion,
the engaging strength of the low engaging-strength portion is less than the engaging strength of the high engaging-strength portion,
the high engaging-strength portion includes a female track and a male track that are configured to engage with each other to close the opening,
the low engaging-strength portion includes a collapsed female track and a male track,
the collapsed female track includes a female track base on the bag body and a deformed female base that protrudes from the female track base toward the male track of the low engaging-strength portion, and
the collapsed female track and the male track of the low engaging-strength portion are configured to close the opening by contacting each other and to open the opening by being separated from each other when a pressure of the internal space rises due to vapor generated from the content accommodated in the internal space.

6. A content sealing container comprising:
the container according to claim 5 ; and
a content accommodated in the internal space,
wherein the opening is sealed.
