Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a box-type container with an inner bag in which an inner bag made of synthetic resin is housed in a paper outer box.
[0002]
[Prior art]
Conventionally, as a liquid packaging container, for example, as described in JP-A-5-229570, JP-A-6-247466, JP-A-7-17564, etc., it is formed of a flexible resin sheet. There is a box-type container with an inner bag in which the inner bag is stored in a paper outer box. In such a box-type container with an inner bag, the inner bag's spout is protruded from an opening hole formed on one surface of the outer box, and in order to improve the shape retention around the inner bag's spout, The part around the spout of the bag is bonded to the inner surface around the opening hole of the outer box.
[0003]
The above-described box-type container with an inner bag is composed of an inner bag made of synthetic resin and an outer box made of paper. Therefore, when disposing without recycling, it is necessary to separate both different materials. . For this reason, as seen in the above-mentioned publication, when the perforation is formed in the outer box and discarded, the outer box is cut and disassembled at the perforation portion, and the inner bag can be taken out. There is something that is.
[0004]
[Problems to be solved by the invention]
As described above, in order to improve the shape retention around the spout of the inner bag, the portion around the spout of the inner bag is bonded to the inner surface around the opening hole of the outer box. It is very difficult to break one surface of the outer box in which the opening hole is formed and to separate the inner bag and the outer box at the bonded portion.
[0005]
[Means for Solving the Problems]
The present invention provides an inner bag formed of a flexible resin sheet and having a spout in a part thereof, and a support surface in which an opening hole for projecting the spout is formed, and a predetermined interval with respect to the support surface An outer box made of paper having a back surface disposed opposite to each other and a peripheral wall surface that surrounds a space facing the support surface and the back surface, and the spout of the inner bag projects from the opening hole. In addition, in a box-type container with an inner bag in which the inner bag is housed in the outer box with the periphery of the spout adhered to the inner surface of the support surface, a part of the rear surface is formed on the rear surface of the outer box. A back break line to be cut is formed from one end of one side that forms a boundary with the peripheral wall surface to the other end, and the opening of the opening hole is formed from both ends of the one side that forms a boundary with the peripheral wall surface on the support surface of the outer box. A support surface breaking line toward both inner edges is formed, and the peripheral wall surface of the outer box Formed by sequences without the two ends of the rear break line in part to cross the two circumferential wall break line toward opposite ends of the support surface break line. Therefore, when a portion between the one side of the back surface of the outer box and the back surface breaking line is pressed, a part of the back surface is broken on the back surface breaking line. If the peripheral wall is pulled by placing a hand on the hole formed in the torn part, the two peripheral wall fracture lines and the supporting surface fracture line that continues to these peripheral wall fracture lines will tear, so a part of the back surface And a part of the peripheral wall surface and a part of the support surface are separated in a continuous state. Thereby, the opening hole of the support surface of the outer box is cut out in a half-moon shape, and a part of the support surface is peeled and removed from a part of the periphery of the spout of the inner bag bonded to the support surface.
[0006]
Here, the back break line, the support surface break line, and the peripheral wall break line are applied with a perforation or a half cut whose depth of cut is equal to or less than the plate thickness of the outer box.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes an outer box having a rectangular parallelepiped shape, and an inner bag 2 is accommodated in the outer box 1. The inner bag 2 has a cylindrical spout 4 that is sealed by a cap 3. The outer box 1 is formed with an opening 5 for projecting the spout 3 and a support surface 6 that supports a portion around the spout 4 of the inner bag 2 in an adhesive state, and a predetermined surface with respect to the support surface 6. It has a back surface 7 that is disposed oppositely with a gap, and peripheral wall surfaces 8, 9, 10, and 11 that surround a facing space between the support surface 6 and the back surface 7.
[0008]
As shown in FIG. 1 (b), the rear surface 7 of the outer box 1 has a back fracture line 12 that cuts out a part of the rear surface 7 from one end of one side 13 that forms a boundary with the peripheral wall surface 11. It is formed toward the end. Further, as shown in FIG. 1A, the support surface 6 of the outer box 1 has a support surface break line 15 that extends from both ends of one side 14 that forms a boundary with the peripheral wall surface 11 toward both inner edges of the opening hole 5. Is formed. Furthermore, a part of the peripheral wall surfaces 8, 9, 11 of the outer box 1, that is, the boundary between the peripheral wall surface 8 and the peripheral wall surface 11 and the boundary between the peripheral wall surface 9 and the peripheral wall surface 11, from both ends of the back fracture line 12. Two peripheral wall breaking lines 16 and 17 that are directed to both ends of the support surface breaking line 15 are formed in parallel without crossing each other.
[0009]
Such an outer box 1 is formed of corrugated paper or the like. FIG. 2 shows a development view of the outer box 1. In this unfolded state, the peripheral wall surface 10 is continuously formed on one side of the peripheral wall surface 8 via the crease 18, and the peripheral wall surface 11 is connected to the opposite side of the peripheral wall surface 8 via the peripheral wall surface breaking line 16. Is formed. Further, a flap 19 is continuously formed on one side of the peripheral wall surface 9 adjacent to the peripheral wall surface 11 when assembled as the outer box 1 via the peripheral wall surface breaking line 17, and on one side opposite to the peripheral wall surface 9. The flap 20 is continuously formed through the fold line 21, and the flap 22 is continuously formed through the fold line 23 on one side of the peripheral wall surface 9 opposite to the support surface 6. Further, flaps 24 and 25 are continuously formed on opposite sides of the support surface 6 via folds 26 and 27, and flaps 28 and 29 are formed on folds 30 on opposite sides of the back surface 7. , 31 are formed continuously.
[0010]
In order to assemble the cardboard paper thus developed as the outer box 1, an adhesive is applied to the hatched area A on the surface of the flaps 19, 20, 22, and 24 and the hatched area B on the inner surface of the support surface 6. 22, the boundaries of the support surface 6, the peripheral wall surface 8, and the back surface 7 are bent on the folds 23, 32, 33, and 34, respectively, and the surface of the flap 22 is bonded to the inner surface of the back surface 7. In this process or after this process, the spout 4 of the inner bag 2 is projected outward from the inside of the opening hole 5 and the periphery of the spout 4 of the inner bag 2 is bonded to the inner surface of the support surface 6. The peripheral wall breaking lines 16 and 17 and the folds 26 and 30 are bent, the flap 28 is overlapped on the inner surface of the flap 19, and the flap 19 and the flap 24 overlapped thereon are bonded to the inner surface of the peripheral wall surface 11. Further, the folds 18, 21, 27, 31 are bent, the flaps 25, 29 are overlapped on the inner surface of the flap 20, and the surface of the flap 20 is bonded to the inner surface of the peripheral wall surface 10.
[0011]
In such a configuration, the contents in the inner bag 2 are replenished to a desired site by removing the cap 3 from the spout 4 protruding from the opening hole 5 of the outer box 1. In the present embodiment, the contents of the inner bag 2 are liquid ink necessary for image formation. Even if the contents in the inner bag 2 are emptied, the contents can be reinjected and reused. Here, a case of disposal will be described.
[0012]
When the contents in the inner bag 2 become empty, the inner bag 2 contracts and leaves the back surface 7 and the peripheral wall surfaces 8, 9, 10, and 11, but the periphery of the spout 4 is adhered to the inner surface of the support surface 6. Maintained. As shown in FIG. 1 (b), when pressing between one side of the back surface 7 and the back surface breaking line 12 with the peripheral wall surface 11 facing upward, the back surface breaking line 12 is torn. When the peripheral wall surface 11 is pulled by placing a hand over the hole formed in the torn part, the two peripheral wall surface fracture lines 16 and 17 and the support surface fracture line 15 continuous to these peripheral wall surface fracture lines 16 and 17 Tears. For this reason, a part of the back surface 7, a part of the peripheral wall surfaces 8 to 11 (the peripheral wall surface 11), and a part of the support surface 6 can be separated in a continuous state. Thereby, most of the inner bag 2 can be easily taken out of the outer box 1. Further, the opening hole 5 of the support surface 6 is cut out in a half-moon shape, and a part of the support surface 6 is peeled off and removed from a part of the periphery of the spout 4 of the inner bag 2 bonded to the support surface 6. The Therefore, the work of peeling off the remaining adhesion portion between the support surface 6 and the inner bag 2 is also easy.
[0013]
In addition, this invention is applicable also when using outer boxes other than a rectangular parallelepiped and a cube shape.
