Abstract

A container includes a bag, which has an internal space to accommodate contents and a first opening, and a fastener to open and close the first opening. The bag places contents into the internal space through the first opening. The bag also has a second opening and also places contents into the internal space through the second opening.

First claim

What is claimed is:

1. A container comprising:
a bag including
an internal space to accommodate a content,
a first opening, and
a second opening, being open so that an entirety of the internal space is in communication with an outside of the bag via the second opening, permitting the content to be received into the internal space through the second opening, the second opening having a thermally sealable portion;

a sealing portion that is detachably provided at a top edge of the bag and to be sealed to close the first opening to the outside of the bag;
a vapor passage portion for removing vapor from the internal space;
a vapor passage sealing portion for closing the vapor passage portion;
a vapor passage guide line for separating the vapor passage sealing portion from the vapor passage portion;
a fastener provided between the first opening and the internal space and being openable and closable, to open and close the first opening to the internal space along a longitudinal direction of the fastener, the fastener being closable when the content is being received into the internal space through the second opening; and
a cutting portion formed at a position corresponding to an end of the vapor passage guide line to be torn across the fastener in a direction other than the longitudinal direction of the fastener, to cut the fastener,
wherein
when the fastener is open and the sealing portion is detached from the bag, the entirety of the internal space is in communication with the outside of the bag via the first opening and the fastener, and the first opening is in communication with the second opening via the internal space and the fastener, and
when the content is accommodated in the internal space and the fastener is open, and when the sealing portion is detached, the content in the internal space is accessible through the first opening and the fastener such that the contents are removable from the internal space through the first opening and the fastener.

2. A container comprising:
a bag including
an internal space to accommodate a content,
a first opening, and
a protruding portion extending outward from a side of the bag and forming a second opening, so that an entirety of the internal space is in communication with an outside of the bag via the second opening, permitting the content to be received into the internal space through the second opening, the protruding portion having a thermally sealable portion;

a sealing portion that is detachably provided at a top edge of the bag and to be sealed to close the first opening to the outside of the bag;
a vapor passage portion for removing vapor from the internal space;
a vapor passage sealing portion for closing the vapor passage portion;
a vapor passage guide line for separating the vapor passage sealing portion from the vapor passage portion;
a fastener provided between the first opening and the internal space and being openable and closable, to open and close the first opening to the internal space along a longitudinal direction of the fastener, the fastener being closable when the content is being received into the internal space through the second opening; and
a cutting portion formed at a position corresponding to an end of the vapor passage guide line to be torn across the fastener in a direction other than the longitudinal direction of the fastener, to cut the fastener,
wherein
when the fastener is open and the sealing portion is detached from the bag, the entirety of the internal space is in communication with the outside of the bag via the first opening and the fastener, and the first opening is in communication with the second opening via the internal space and the fastener, the bag further includes a bag body forming the internal space,
the protruding portion is extending outward of the bag from a lateral portion of the bag body, and
the protruding portion extends in a first direction, and the second opening is formed in a middle of the lateral portion in a second direction that is orthogonal to the first direction.

3. The container according to claim 2 , wherein
the container has a form of a free-standing container and includes a bottom gusset, and
the bottom gusset supports the bag body.

4. The container according to claim 1 , wherein the fastener includes a high engaging-strength portion and a low engaging-strength portion.

5. The container according to claim 4 , wherein the low engaging-strength portion has an engaging strength in a range of 0% to 90% of an engaging strength of the high engaging-strength portion.

6. The container according to claim 4 , wherein a length of the low engaging-strength portion in the longitudinal direction of the fastener is in a range of 5% to 70% of a length of the fastener in the longitudinal direction.

7. The container according to claim 1 , wherein
the bag includes
an opening sealing portion formed at an edge of the first opening to close the first opening, and
an opening guide line to separate the opening sealing portion from the first opening,

the opening sealing portion can be separated from the first opening along the opening guide line,
the vapor passage sealing portion can be separated from the vapor passage portion along the vapor passage guide line,
the first opening is formed to be continuous with the vapor passage portion,
the opening sealing portion is formed to be continuous with the vapor passage sealing portion,
the fastener is formed to bridge the first opening and the vapor passage sealing portion and includes an opening fastener portion located on the first opening and a vapor passage fastener portion located on the vapor passage sealing portion.

8. The container according to claim 7 , wherein
the bag includes a bag predetermined portion located closer to the internal space than the fastener, and
the cutting portion includes
an intermediate cutting portion to cut the fastener,
a first predetermined cutting portion that is continuous with the intermediate cutting portion and cuts the bag predetermined portion,
a second predetermined cutting portion located at an end of the first predetermined cutting portion that is closer to the internal space, and
a separating portion to separate the first predetermined cutting portion from the second predetermined cutting portion.

9. The container according to claim 7 , wherein
the bag includes, on an extension of the cutting portion
a cutting restraining portion, and
a sealing portion having at least the opening sealing portion and the vapor passage sealing portion, and

the cutting restraining portion functions to prevent cutting of the sealing portion along the extension of the cutting portion from reaching the internal space.

10. The container according to claim 1 , wherein
the bag further includes an openable sealing portion to open and close the first opening, and
the openable sealing portion is formed between the fastener and the internal space in the first opening.

11. A content sealing container comprising:
the container according to claim 1 ; and
the content, accommodated in the internal space of the container.

12. The container according to claim 1 , wherein
the bag further includes a bag body forming the internal space;
the container has a form of a free-standing container and includes a bottom gusset, and
the bottom gusset supports the bag body.

13. The container according to claim 2 , wherein
the bag further includes an openable sealing portion to open and close the first opening, and
the openable sealing portion is formed between the fastener and the internal space in the first opening.
