Abstract

PROBLEM TO BE SOLVED: To hold a bag-in-box with a spout in a protruded condition. SOLUTION: A pair of holding pieces 3 with a bent base folding line 2 is provided by cutting a plate 1 forming an inner flap 24 of an outer box 21, an inner folding line 4 and an axial folding line 5 are formed in the holding pieces 3 and on the outer side thereof, respectively, through a center part of the base folding line 2. While the plate 1 is valley-folded along the base folding line 2 and the axial folding line 5, the holding pieces 3 are ridge-folded along the inner folding line 4, a spout 13 of a liquid-filled bag 12 is pulled out from a space of the holding pieces 3 facing each other, and a neck part thereof is engaged with tips of the holding pieces 3. The spout 13 is held in a largely protruded condition from the outer box 21, and liquid drip is prevented when the liquid is poured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding a spout of a bag-in-box in which a liquid bag is stored in an outer box.

[0002]

2. Description of the Related Art Conventionally, when delivering liquids such as beverages, seasonings, and detergents used for business use to stores and the like, a bag-in-box in which these liquids are packed in a plastic bag and stored in an outer box has been used. ing.

A spout is provided in the liquid bag, and when the liquid in the bag is used in a store or the like, a part of the outer box is cut off while the liquid bag is stored in the outer box. The liquid is poured from the spout while the spout is pulled out and the spout is fixed to the cutting edge of the outer box.

[0004]

However, in the conventional bag-in-box, the spout of the liquid bag may collapse during transportation, making it difficult to fix the spout to the outer box.

[0005] Further, since the amount of protrusion of the spout fixed to the outer box is small, there is also a problem that liquid dripping easily occurs when the liquid is transferred from the spout to another container.

Accordingly, an object of the present invention is to provide a bag-in-box spout holding structure capable of holding the spout in a protruding state.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a pair of holding pieces are provided in which a base material is bent by cutting a board made of cardboard, and the holding piece passes through the center of the base folding line to be attached to the holding piece. The center folding line is formed with an axis folding line on the outside, and while holding the plate material along the base folding line and the axis folding line, the holding piece is mountain-folded along the middle folding line, and the liquid filling bag is inserted from the gap between the opposite holding pieces. Was pulled out and its neck was engaged with the tip of the holding piece.

When this holding structure is applied to a pad for holding a spout of a liquid bag inside an outer box, the spout is prevented from depressing, so that the spout can be easily fixed to the outer box.

Further, when this holding structure is applied to the flap of the outer box, the spout is held in a state of protruding greatly from the outer box, so that dripping during pouring is prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which a holding structure according to the present invention is applied to a pad for holding a spout of a liquid bag in an outer box,
This will be described with reference to FIGS.

As shown in FIG. 1, this pad is provided with a pair of holding pieces 3 each having a base line 2 formed into a V-shape by cutting a board material 1 made of corrugated cardboard.
The center folding line 4 is formed on the outside, and the axial folding line 5 is formed on the outside thereof, and a gap is provided between both sides and the tip of the opposing holding piece 3.

When this pad is used, as shown in FIG. 2, while holding the plate material 1 along the base fold line 2 and the axis fold line 5, the holding piece 3 is mountain-folded along the center fold line 4. . As a result, the holding piece 3 stands up, and the gap is enlarged to a hexagon.

The liquid bag 12 stored in the outer box 11
3 and 4, the spout 13 is pulled out from the gap between the opposing holding pieces 3 and the collar 14 of the neck is engaged with the tip of the holding piece 3 as shown in FIGS. .

When the outer box 11 is sealed in such a state, the spout 13 is held in a state of protruding from the surface of the liquid bag 12 without being collapsed during transportation. The outlet 13 can be easily fixed to the outer case 11.

In this pad, the center folding line 4 is
In order to facilitate mountain folding, it is preferable to use a lead ruled line with a cut in the press ruled line or a half-cut lined line in which a liner on one side is cut. The base fold line 2 may be bent in a U-shape.

Next, an example in which the holding structure according to the present invention is applied to a flap of an outer box will be described with reference to FIGS.

In the blank of the outer box 21, as shown in FIG. 5, four body plates 22 are provided in a row, and a passage piece 23 is provided on one side thereof. Flaps 24 and 25 are alternately connected to the upper and lower edges of each body plate 22, and one of the upper flaps 24 is a plate member 1 having the same configuration as the pad.

On both sides of the plate 1, cuts 26 are provided from the leading edge to the axial fold line 5.
A zipper 27 is provided from a side edge adjacent to.

Such a blank is assembled as shown in FIG.
Are sequentially folded, bonded together outside the zipper 27, and delivered to a store or the like.

Then, in a store or the like, as shown in FIG. The holding piece 3 is folded in a pile, and the spout 1
3 is pulled out from the gap between the opposing holding pieces 3, and the collar 14 of the neck is engaged with the tip of the holding piece 3.

As described above, when the holding structure is applied to the flap 24 of the outer box 21, the spout 13 can be easily set on the outer box 21, so that the spout 13 protrudes greatly from the outer box 21. Since the liquid is held, dripping at the time of pouring is prevented.

As shown in the figure, a cock 15 may be attached to the spout 13 as necessary, and the outer box 21 may be set upside down.

[0023]

As described above, in the holding structure according to the present invention, the neck of the spout is engaged with the tip of the holding piece that is erected by combining the valley fold and the mountain fold. Is applied to the pad that holds the spout of the liquid bag in the outer box, the spout is prevented from depressing, and the spout can be easily fixed to the outer box.

Further, when this holding structure is applied to the flap of the outer box, the spout is held in a state of being greatly protruded from the outer box, so that loss of liquid due to liquid dripping at the time of pouring is reduced, and the floor becomes dirty. Are also prevented.
