[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called bag-in-box liquid storage container in which a bag with a spout is housed in a carton and the spout is projected from the carton. It is.

[0002]

2. Description of the Related Art Conventionally, as a liquid storage container, for example, there is a liquid storage container disclosed in JP-A-60-99870. As shown in FIG. 5, the liquid storage container 1 uses a block-shaped carton 2 and has a spout 3 with a part of the upper part inclined. Then, as shown in FIG. 6 showing a state in which the upper part is opened, a flap (inclined portion) 5 and a side wall 6 (in the drawing, which are projected and locked by the spout 3 of the bag (provided in the carton) 4). Before and after)
A fold 8 in which two triangular flaps 7, 7 are continuous is provided in between to facilitate the assembly of the carton and to ensure that the bag fits into the carton with the ramp. ing.

[0003] In recent years, there is a case where the amount of the contents to be discharged is measured depending on the contents (for example, liquid detergent) stored in the liquid storage container. A container having such a content uses a cap having a measuring section. Then, as shown in FIG. 5, when the cap b having the measuring portion a protruding inward through the spout port at the time of setting is to be used, particularly when the diameter of the measuring portion is large, the folded portion is folded inward. Since it is projected and protruded, this folded portion becomes an obstacle. Therefore, in the applicant,
In order to avoid interference between the measuring portion and the folded portion of the cap b, it has been devised to provide a cutout portion in the folded portion.

[0004] This is applied to the carton 2 of the liquid container 1 shown in FIG.
Will be described in an expanded state. In other words, the fold 8 located between the inclined flap 5 and the side walls 6, 6 has an inner fold line 9 located over the center of the fold 8 so that a portion corresponding to the measuring portion of the cap is provided. Each of the cutouts 10 is obtained by punching out a substantially elliptical shape. In the figure, reference numeral 11 denotes a sticking portion for fixing the bag. When the cap b is attached to the spout 3 in this manner, the folds 8, 8 are in a state of being folded out toward the measuring section a.
The notch 10 is located at a position corresponding to the weighing section a, so that the notch 10 does not interfere with the weighing section a and the folding section 8 as it escapes from the weighing section a (see FIG. 8).

Further, as shown in FIG. 9, the opening 13 is formed into a substantially rhombic shape from the lower end side of the inner folding line 9 and the opening 13 is punched out with a slight overhanging piece 12 left on the side wall 6 side. A device has been devised. The length of the projecting piece 12 is the same as the length of the end face 5a of the flap 5, and the projecting dimension is at least the thickness of the carton material. This contrivance, namely, the opening 13 and the overhanging piece 12
, Breakage of the carton material due to concentration of the folding line (when the carton is assembled)
In addition, the end face 5a of the flap 5, which is the peripheral edge of the opening 13, is not exposed to the side, and the appearance is adjusted. As shown in FIG. 10, when the carton 2 is assembled, there is no swelling due to the concentration of the crease lines, and the overhanging pieces 12 cover the end faces.

[0006]

However, in the above-mentioned container, since the inner folding line is located over the center of the folding portion as described above, depending on the system of the box making line, Points have to be considered. In other words, since the inner folding line 9 is provided at the center of the folded portion 8, when the flap 5 is folded down, the inner folding line 9 is firstly bent and the central portion of the folded portion 8 tends to have no waist. For this reason, stress concentration is not generated enough to reliably bend the fold line portion 14 between the fold portion 8 and the side wall 6, and the fold portion 8 is folded with the bulge remaining in the fold line portion 14. (See FIGS. 11 and 12), which impaired the appearance of the container.

In view of the above circumstances, it is an object of the present invention to ensure that the folded line portion when the flap is folded down can be reliably bent, and the folded state of the folded portion is improved to improve the appearance of the container. The purpose is to arrange.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been made in consideration of the above-mentioned conventional problems. A bag with a spout is accommodated in a carton, and the spout is formed from an inclined flap of the carton. In the protruding liquid storage container, an inner fold line having a cutout of a fold portion located between the flap provided with the spout and the carton side wall is provided so as to be deviated from the center of the fold portion toward the carton side wall. It is intended to solve the above-mentioned problem by providing a liquid storage container characterized by the following.

[0009]

According to the present invention, when the flap 5 is folded down, the flap 7 (the flap 5 side) of the folded portion 8 is connected to the flap 7 'as it curves inward.
(Carton side wall 6 side) is pushed in such that it is strongly folded inward, so that stress is concentrated on the portion of the fold line 14 to be surely bent.

[0010]

Next, a detailed description will be given based on the embodiment shown in FIGS. In addition, the same reference numerals are given to portions having the same configuration as the conventional example shown in FIGS. 5 to 12, and the description thereof will be omitted. That is, in the present invention, as shown in FIG.
those provided by partially倚from a carton side wall 6 side.
As described above, the inner fold line 9 is deviated, and the notch 10 is provided so as to extend along the inner fold line 9. Therefore, when the flap 5 is folded, the flap 7 is bent and the flap 7 ′ is moved inward. As a result, the flap 7 ′ can be reliably bent from the fold line 14, so that the fold 8 does not fold and bulge, so that the appearance is not impaired as shown in FIG. 10, for example. .

The folded portion 8 is not limited to the shape shown in FIG. 1, but, for example, as shown in FIG. You may do so. Also, the shape of the notch 10 is not limited to the illustrated elliptical shape, but can be set appropriately, such as a circular shape or a slit shape.

[0012]

[Effects of the Invention] As described above, according to the present invention,
The liquid storage container is a container in which a bag with a spout is housed in a carton and the spout is projected from an inclined flap of the carton, and is located between the flap with the spout and a carton side wall. With notches in the fold
The inner fold line is deviated from the center of the fold to the side of the carton side wall, so that when the flap provided with the spout is folded over, the fold line between the fold and the carton side wall is reliably folded. In other words, even when the folded portions are folded, no swelling occurs at the folded line portion, and the effect of excellent practicality is exhibited, such as the appearance of the container is not impaired.
