ABSTRACT:

TECHNICAL FIELD
This invention relates to a gusseted bag useful as a rebottling container.
BACKGROUND ART
In recent years, to cope with problems of trash which are caused by disposal of plastic bottles, it has become popular to take the form of distribution that contents are sold by putting them into rebottling containers such as standing pouches or gusseted bags and consumers rebottle the contents into bottle containers to put them into use.

is opened by cutting off its upper part along a broken line L.
As shown in these drawings, the gusseted bags
1
x
and
1
y
are bag-like containers having inward-folded V-shaped folds at their opposing both sidewalls
3
, and these V-shaped folds at the both sidewalls are greatly characteristic of the gusseted bags in contrast with the standing pouches.
When a consumer makes use of the contents with which the
FIG. 21
gusseted bag
1
x
is filled, the consumer cuts off a sealed portion
4
at the top of the bag at any desired position, using scissors or the like, and rebottles the container into a certain bottle container.
In the case of the gusseted bag
1
y
shown in
FIGS. 22
to
24
, it has the sealed portion
4
also at the vertical edges of the bag, and the distance between inside contours
4
a
of sealed portions
4
set opposite one another in the horizontal direction is narrowed toward the upper part with respect to the body of the bag, thus the unsealed portion positioned between these opposing inside contours
4
a
serves as the pour spout
2
. Accordingly, when a consumer makes use of the contents with which the gusseted bag
1
y
is filled, the consumer cuts off the upper part of the gusseted bag
1
y
filled with the contents, along a broken line L using scissors or the like to open the pour spout
2
as shown in
FIG. 24
, and rebottles the container into a certain bottle container.
However, no pour spout is formed in the conventional gusseted bag
1
x
shown in
FIG. 21
, and hence it is difficult for the consumer to rebottle the contents into a bottle container, where problems have occurred such that the contents spill or are scattered around.
In the gusseted bag
1
y
shown in
FIG. 23
, the pour spout
2
is formed, but the sealed portions
4
around the pour spout
2
still remain as extensions of the sealed portions at the vertical edges of the body of the bag. Hence, when the contents are rebottled into a narrow-necked bottle container, the pour spout
2
of the gusseted bag
1
y
can not be inserted into the mouth of such a bottle container to cause the problems that the contents spill or are scattered around.
The present invention aims at solving the problems in the prior art as stated above. Accordingly, an object of the present invention is to provide a gusseted bag from which the contents can be rebottled with ease and for sure even into narrow-necked bottle containers.
DISCLOSURE OF THE INVENTION
To achieve the above object, the present inventors provide a gusseted bag comprising a bag having i) inward-folded V-shaped folds at its opposing both sidewalls and ii) sealed portions at vertical edges of the upper part of the bag; wherein, at the upper part of the bag, the distance between inside contours of the sealed portions set opposite one another in the horizontal direction is narrowed with respect to the body of the bag to form a non-sealed portion serving as a pour spout, and outside contours of the sealed portions forming the pour spout form an outer shape narrowed with respect to the body of the bag.
In particular, in this gusseted bag, an embodiment is provided in which the pour spout is positioned eccentrically toward one side of the sidewalls, and an embodiment in which the bag has, at a wall surface portion forming the pour spout, a ruled line so formed that the wall surface portion is foldable outward.
According to the gusseted bag of the present invention, the outside contours of the sealed portions forming the pour spout form an outer shape narrowed with respect to the body of the bag. Hence, when the contents of the gusseted bag are rebottled into a certain container, the contents can be rebottled by inserting the pour spout of the gusseted bag into the mouth of the container even if the container is a narrow-necked bottle container. Accordingly, the contents can be prevented from splitting or being scattered around, and the rebottling can be operated with ease.
In particular, in the gusseted bag of the present invention, according to the embodiment in which the pour spout is positioned eccentrically toward one side of the sidewalls and the embodiment in which the bag has, at a wall surface portion forming the pour spout, a ruled line so formed that the wall surface portion is foldable outward, the pour spout can be readily opened even if it has a narrow neck, and hence the contents can be more easily rebottled from the gusseted bag to the bottle container.
