Abstract

(57) [Summary] [Purpose] To ensure that the fold lines are folded properly when the flaps are folded down, and to make the folds of the folds good so that the appearance of the container is adjusted. [Structure] A cap is attached to the spout of the carton 2, and a measuring portion provided on the cap projects inward of the bag through the spout. In this carton 2, there is a folding part 8 between the flap 5 to which the spout is attached and the carton side wall 6, and this folding part 8

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a so-called bag-in-box liquid storage container having a structure in which a bag with a spout is stored in a carton and the spout is projected from the carton.

[0002]

[Prior Art]

 Conventionally, as a liquid storage container, for example, there is one disclosed in JP-A-60-99870. As shown in FIG. 5, this liquid container 1 uses a block-shaped carton 2, and a spout 3 is arranged with a part of the upper part inclined. Then, as shown in FIG. 6 showing the state in which the upper part is opened, a flap (inclined portion) 5 and a side wall 6 (in the drawing) on which the spout 3 of the bag (which is provided in the carton) 4 is locked and protrudes. , The front and rear) are provided with a folding part 8 in which two triangular flaps 7 and 7 are continuous to facilitate the assembling of the carton and ensure that the bag is inside the carton having the inclined part. It is designed to fit.

In recent years, depending on the content (eg, liquid detergent) stored in a liquid storage container, the amount of the content poured out may be measured and used. A cap having a measuring unit is used in a container containing such contents. Then, as shown in FIG. 5, when a cap b having a measuring portion a that protrudes inward of the bag through the spout is used at the time of setting, especially when the diameter of the measuring portion is large, the folding portion is folded inward. Since it is ejected and protrudes, this folded part is an obstacle. Therefore, the present applicant has devised to provide a cutout portion in the folding portion in order to avoid interference between the weighing portion of the cap b and the folding portion.

This will be described in a state where the carton 2 of the liquid storage container 1 in FIG. 7 is expanded. That is, the folding part 8 located between the slanting flap 5 and the side walls 6 and 6 is attached to the inner folding line 9 located across the center of the folding part 8 so that the measuring part of the cap is covered. Corresponding portions are cut out, and each of the cutouts 10 is obtained by punching and forming in a substantially elliptical shape. In addition, reference numeral 11 in the figure denotes an adhesive portion for fixing the bag. In this way, when the cap b is attached to the spout 3, the folding parts 8, 8 are folded to the side of the measuring part a, but the cap 8 is placed at the position corresponding to this measuring part a. There is a notch 10 so that the measuring portion a and the folding portion 8 do not interfere with each other when the measuring portion a escapes from the measuring portion a (see FIG. 8).

Further, as shown in FIG. 9, the opening 13 is punched and formed from the lower end side of the inward folding line 9 in a substantially rhombic shape, and a slight protruding piece 12 is left on the side wall 6 side. Ingenuity is being made. The length of the overhanging piece 12 is the same as the length of the end surface 5a of the flap 5, and the overhanging dimension is at least the thickness of the carton material. This device, that is, the opening 13 and the overhanging piece 12 are provided, so that breakage of the carton material (at the time of assembling the carton) due to concentration of folding lines can be prevented, and the opening 13 can be prevented. The edge 5a of the flap 5, which is the peripheral edge, 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 folding ruled lines, and the end face is hidden by the overhanging piece 12.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned container, since the inner folding line is located over the center of the folding part as described above, it becomes necessary to consider the following points depending on the box making line system. .. That is, since the inner folding line 9 is provided at the center of the folding portion 8, when the flap 5 is folded down, the inner folding line 9 is first folded and the waist is easily lost in the central portion of the folding portion 8. For this reason, stress concentration enough to surely bend the portion of the folding line 14 between the folding portion 8 and the side wall 6 does not occur, and the folding portion 8 is left with the bulge left in the portion of the folding line 14. It was sometimes folded (see FIGS. 11 and 12), which impaired the appearance of the container.

In view of the above-mentioned circumstances, it is an object of the present invention to surely fold the above-mentioned fold line portion when the flap is folded down. The purpose is to arrange the appearance of.

[0008]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above-mentioned conventional problems, and in a liquid storage container in which a bag with a spout is stored in a carton and the spout is projected from an inclined flap of a carton, Provided is a liquid storage container characterized in that an inner fold line of a folding portion located between the flap having a spout and a side wall of the carton is provided so as to be offset from the center of the folding portion toward the side wall of the carton. The above problems are solved.

[0009]

[Action]

 According to the present invention, when the flap 5 is folded down, the flap 7 '(flap 5 side) of the folding portion 8 is curved inward and the flap 7' (carton side wall 6 side) continuously attached thereto is strongly strengthened. As it is pushed inward so as to be folded down, stress concentrates on the portion of the fold line 14 and the crease is surely bent.

[0010]

【Example】

 Next, a detailed description will be given based on the embodiment shown in FIGS. It should be noted that the same parts as those of the conventional example shown in FIGS. That is, in the present invention, as shown in FIG. 1, an inner fold line 9 is provided on the folding portion 8 so as to change from the center line 8a of the folding portion 8 to the carton side wall 6 side. Since the inner folding line 9 is biased in this way, and the notch 10 is provided so as to overlap the inner folding line 9, when the flap 5 is folded, the flap 7 is curved while the flap 7'is bent inward. The flap 7'is surely bent from the fold line 14 so that the folding part 8 does not fold to form a bulge and the appearance is not spoiled as shown in FIG. 10, for example. become.

The folding portion 8 is not limited to the shape shown in FIG. 1. For example, as shown in FIG. 4, the upper edge of the folding portion 8 is bent into a substantially <shape at the portion of the inner folding line 9. You may ask. The shape of the notch 10 is not limited to the oval shape shown in the figure, and can be appropriately set to a circular shape, a slit shape, or the like.

[0012]

[Effect of the device]

 As described above, according to the present invention, a liquid container is a container in which a bag with a spout is stored in a carton and the spout is projected from an inclined flap of the carton. The inner fold line of the folding part located between the flap where the outlet is arranged and the carton side wall is provided so as to be biased from the center of the folding part to the carton side wall side. The folding line between the folding part and the side wall of the carton can be securely folded, and the folding line does not bulge even when the folding part is folded, and the appearance of the container is not impaired. It is effective.
