Abstract

A pouch container is provided with sack-like portions provided respectively to upper parts of the front-surface sheet and the rear-surface sheet.

First claim

The invention claimed is:

1. A pouch container comprising:
at least a pair of wall surface sheets, one of the wall surface sheets constituting a front surface portion and the other of the wall surface sheets constituting a back surface portion;
a filling portion being surrounded by the wall surface sheets; and
an opening formed between the front surface portion and the back surface portion on a first side of the pouch container in a longitudinal direction, the opening being connected to the filling portion;
a pair of bag-shaped portions, one of the bag-shaped portions being provided in the front surface portion and the other of the bag-shaped portions being provided in the back surface portion;
a zipper configured to close the opening;
flap-shaped portions extending upwards from the zipper to the first side of the pouch container in the longitudinal direction;
a seal portion configured to join together portions of the flap-shaped portions, the portions of the flap-shaped portions being disposed on a side closer to the first side of the pouch container in a lateral direction, the seal portion being provided between the portions of the flap-shaped portions, wherein:
the bag-shaped portions are disposed in the flap-shaped portions, and
at least one of the pair of bag-shaped portions is formed by joining a periphery of an inner sheet inserted between the wall surface sheets to an inner surface of a corresponding one of the wall-surface sheets, the at least one bag-shaped portion includes: (i) an internal space separated from the filling portion, and (ii) an insertion opening formed on a corresponding one of the wall surface sheets to enable insertion of a finger into the internal space from one side of the pouch container in the lateral direction.

2. The pouch container according to claim 1 , wherein:
the insertion opening is provided in the at least one bag-shaped portion on a side closer to the second side of the pouch container in the lateral direction.

3. The pouch container according to claim 2 , wherein:
the seal portion is formed so as to be inclined in the longitudinal direction and the lateral direction so that an aperture of the flap-shaped portions gradually becomes smaller toward the zipper.

4. The pouch container according to claim 3 , wherein:
the at least one bag-shaped portion has a tongue piece for closing the insertion opening; and
the insertion opening is opened by folding the tongue piece into the internal space.

5. The pouch container according to claim 4 , further comprising:
an outlet portion provided on the other end side in the longitudinal direction, a flexible long tube being attached to the outlet portion; and
an edge seal portion formed by joining edges of the front surface portion and the back surface portion to each other, wherein:
a tube-holding portion is formed in the edge seal portion, for holding the tube; and
the tube-holding portion is formed by cutting in or cutting out the wall surface sheets from an outer end of the edge seal portion by a length equal to or greater than the diameter of the tube.

6. The pouch container according to claim 5 , wherein the tube holding portion comprises:
an introduction path which has a width smaller than the diameter of the tube; and
a housing hole which is connected to the introduction path and is equal in size with or larger than the tube.

7. The pouch container according to claim 6 , wherein the tube-holding portion has a tongue piece which covers at least a portion of the housing hole and contacts the tube when the tube is inserted into the housing hole.

8. The pouch container according to claim 7 , wherein:
the edge seal portion has widened seal portions which are formed by widening the width of the edge seal portion locally; and
a suspension hole and the tube-holding portion are formed in one of the widened seal portions.

9. The pouch container according to claim 5 , wherein the tube-holding portion has a tongue piece which covers at least a portion of a housing hole and contacts the tube when the tube is inserted into the housing hole.

10. The pouch container according to claim 9 , wherein:
the edge seal portion has widened seal portions which are formed by widening the width of the edge seal portion locally; and
a suspension hole and the tube-holding portion are formed in one of the widened seal portions.

11. The pouch container according to claim 5 , wherein:
the edge seal portion has widened seal portions which are formed by widening the width of the edge seal portion locally; and
a suspension hole and the tube-holding portion are formed in one of the widened seal portions.

12. The pouch container according to claim 2 , wherein:
the at least one bag-shaped portion includes a tongue piece for closing the insertion opening; and
the insertion opening is opened by folding the tongue piece into the internal space.

13. The pouch container according to claim 12 , further comprising:
an outlet portion provided on the other end side in the longitudinal direction, a flexible long tube being attached to the outlet portion; and
an edge seal portion formed by joining edges of the front surface portion and the back surface portion to each other, wherein:
a tube-holding portion is formed in the edge seal portion, for holding the tube; and
the tube-holding portion is formed by cutting in or cutting out the wall surface sheets from an outer end of the edge seal portion by a length equal to or greater than the diameter of the tube.

14. The pouch container according to claim 13 , wherein:
the edge seal portion has widened seal portions which are formed by widening the width of the edge seal portion locally; and
a suspension hole and the tube-holding portion are formed in one of the widened seal portions.

15. The pouch container according to claim 1 , wherein:
the at least one bag-shaped portion has a tongue piece for closing the insertion opening; and
the insertion opening is opened by folding the tongue piece into the internal space.

16. The pouch container according to claim 15 , further comprising:
an outlet portion provided on the other end side in the longitudinal direction, a flexible long tube being attached to the outlet portion; and
an edge seal portion formed by joining edges of the front surface portion and the back surface portion to each other, wherein:
a tube-holding portion is formed in the edge seal portion, for holding the tube; and
the tube-holding portion is formed by cutting in or cutting out the wall surface sheets from an outer end of the edge seal portion by a length equal to or greater than the diameter of the tube.

17. The pouch container according to claim 16 , wherein:
the edge seal portion has widened seal portions which are formed by widening the width of the edge seal portion locally; and
a suspension hole and the tube-holding portion are formed in one of the widened seal portions.

18. The pouch container according to claim 1 , further comprising:
an outlet portion provided on the other end side in the longitudinal direction, a flexible long tube being attached to the outlet portion; and
an edge seal portion formed by joining edges of the front surface portion and the back surface portion to each other, wherein:
a tube-holding portion is formed in the edge seal portion, for holding the tube; and
the tube-holding portion is formed by cutting in or cutting out the wall surface sheets from an outer end of the edge seal portion by a length equal to or greater than the diameter of the tube.
