However, since the liquid spout of the inner bag is fitted into and fixed to a part bent inwardly, the outer box is fixed to the outer box in a so-called member supported state. For this reason, when attaching or detaching a cap or a hose to the liquid ejection outlet, the liquid ejection outlet is press-fitted into the outer box and recessed, and the detachment operation may be difficult.

Therefore, in view of the above-described conventional problems, the present invention forms a long hole in which the operator can insert a finger in the vicinity of the portion where the liquid ejection outlet is fitted and fixed, whereby a part of the outer box in the cantilevered state is connected to the ceiling portion. An object of the present invention is to provide a bag-in box which can be gripped together and prevents the liquid ejection port from sinking.

To this end, in the present invention, a substantially rectangular parallelepiped outer box including four side plates forming a main body portion, a ceiling plate forming a ceiling portion of a double structure, and a bottom plate forming a bottom portion of a double structure are formed. In the bag-in box which accommodates the inner bag in which the liquid spout which integrated the cap or hose detachably screwed is accommodated, the position spaced a predetermined distance from the upper end of the side plate connected to the ceiling plate located inside the double structure. Is a bend line, the inwardly U-shaped cutout extending from the bend line to the ceiling plate direction is bent inward, and the liquid spout is inserted from the bend line of the portion enclosed by the cutout to the tip part. The outside of the double structure is provided while a fixing hole for fitting and fixing a long hole into which a finger can be inserted in this order. The part facing the fixing holes and the long holes in the top plate location to form a cut as possible perforations.

According to the present invention, when the bag-in box is used for the first time, the tear line formed in the ceiling plate located outside of the double structure is broken, and the portion facing the fixing hole and the long hole is cut out. Then, the cap or the hose is attached to or detached from the liquid ejection outlet, while the finger plate is inserted from the long hole to hold the portion where the ceiling plate and the liquid ejection outlet are fitted together to be fixed. In this way, even if an external force that presses the liquid ejection outlet into the outer box acts, since it is integrated with the ceiling, the cap or hose can be attached and detached easily. In addition, since the fixing hole and the long hole are covered by the ceiling plate located outside of the double structure before the bag in box is used, it can be easily recognized that it is not in use.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

Figure 1 shows a perspective view of an outer box of the bag in box embodying the present invention.

The bag in box 10 includes four side plates forming the main body 12, a ceiling plate forming the double ceiling 14, and a bottom plate forming the double bottom 16. For the substantially rectangular parallelepiped outer box 18 configured therein, an inner bag (not shown) incorporating a liquid outlet for detachably screwing a cap or hose is accommodated. The bent line 20 is a position spaced apart from the upper end of the side plate connected to the ceiling plate located inside the double structure by a predetermined distance D, and the inverted shape having an approximately inverted shape in which the tip portion extends from the ceiling plate direction from this is Fixing hole 22 for fitting and holding the liquid ejection outlet from the bend line 20 of the part enclosed by the incision and toward the tip part, and the long hole 24 by which an operator can insert a finger. This is established in this order. In addition, the ceiling plate located outside the double structure is provided with a cutout line 26 which can cut a portion facing the fixing hole 22 and the long hole 24.

The specific structure of the outer box 18 is the inner side which is a pair and double structure which opposes the upper end part and the lower end part of the four side plates 12A-12D which the adjacent end parts connected, like the development figure shown in FIG. And the four top plate members 14A to 14D and the bottom plate members 16A to 16D are connected to each other to form a top plate and a bottom plate positioned on the outside. A bent line 20 is formed at a position spaced apart by a predetermined distance D from an upper end of the side plate 12C connected to one ceiling plate member 14C forming a ceiling plate located inside the double structure. From this, a substantially inverted c-shaped cut 28 is formed in which the tip portion extends in the direction of the ceiling plate member 14C. Here, the predetermined distance (D) is that when the outer box 18 is assembled as shown in FIG. It is preferable to set larger than the height. In addition, in the portion enclosed by the substantially inverted c-shaped cutout 28, a fixing hole 22 for fitting and fastening the liquid inlet from the bend line 20 toward the tip portion thereof, and a long hole through which an operator can insert a finger ( 24) is opened in this order. In addition, in the ceiling plate members 14B and 14D which form the ceiling plate located outside of the double structure, the perforation line which can cut out the part which faces the fixing hole 22 and the long hole 24 when the outer box 18 is assembled | assembled (26) and a pair of mounting holes 30 for fitting and fixing both ends of the handle which form a substantially bow shape are formed, respectively. In addition, in one bottom plate member 16A that forms the bottom plate located outside of the double structure, a hanging hole for the operator to hang the fingertips for the purpose of making it easier to hold the bottom of the outer box 18. (32) is established.

In addition, the substantially trapezoid-shaped member 34 connected to the side plate 12D located in the rightmost part in the figure is a mounting table for connecting side plates.

Next, the operation of the bag in box 10 having such a configuration will be described.

When pouring out the liquid contained in the bag-in box 10, the perforated line 26 formed in the top plate members 14B and 14D located in the outer side of the double structure is destroyed, and the fixing hole 22 and the long hole 24 are closed. Tear off the part that you do not like. In this way, the cap 38 and the long hole 24 screwed to the liquid spout integrated into the inner bag can be exposed to the outside. In addition, this operation may be performed only once when starting to use the back in box 10. FIG. At this time, since the cap 38 and the long hole 24 are covered by the top plate members 14B and 14D located on the outside of the double structure before the bag in box 10 is used, it can be easily recognized that it is not in use. have. In addition, in order to ease the maintenance of the outer box 18 and to reduce the labor required for dispensing the liquid, as shown in FIG. 3, a pair of mounting holes 30 formed in the top plate members 14B and 14D. Fit both ends of the handle 36 to fit.

Then, as shown in Fig. 4, after inserting the fingertips from the long hole 24, as shown in Fig. 5, the ceiling plate members 14A to 14D and the liquid ejection port 40 which form the ceiling part of the double structure. The cap 38 is removed from the liquid spout 40 while the gripping portions are held together. At this time, even if an external force that presses the liquid ejection opening 40 into the inside of the outer box 18 acts, since it is integrated with the ceiling portion 14, it is not recessed, so that the cap 38 can be easily removed. . When the removal of the cap 38 is completed, the hose 42 is screwed into the liquid ejection outlet 40 via the same sequence as shown in FIG. 6, and the handle 36 as shown in FIG. ) And the holding box 32 formed in the bottom plate member 16A while tilting the outer box 18 to eject the liquid. On the other hand, when the dispensing operation of the liquid is completed, the removal of the hose 42 and the screwing of the cap 38 may be sequentially performed in the same order.

Therefore, according to such back-in box 10, the finger inserted from the elongate hole 24 can be integrated by holding the part in which the ceiling part 14 and the liquid ejection outlet 40 of the double structure were fitted and fixed. Therefore, even when the cap 38 or the hose 42 is attached or detached, the depression can be prevented even if an external force that presses the liquid ejection opening 40 into the inner box 18 acts. For this reason, the attaching / detaching work of the cap 38 or the hose 42 can be performed easily.

4 and 5, when the base portion of the liquid ejection opening 40 is formed to have a larger diameter than the fixing hole 22, the liquid ejection opening 40 can be formed by repeated use of the bag in box 10. When the periphery of is broken, by supporting the base with the fingertip inserted from the long hole 24, it can be prevented from sinking. Further, as shown in Fig. 4, there is a gap between the top plate members 14A and 14C forming the top plate located inside and the portion where the liquid ejection port 40 is fitted and fixed, so that a fingertip is inserted therein. As a result, the back in box 10 can be easily transported or the like. In addition, the cap 38 screwed to the liquid spout 40 is accommodated between the bend line 20 and the top plate members 14A and 14C located inside, as shown in Figs. Since the cap 38 does not protrude upward from the upper surface of the outer box 18, for example, the bag in box 10 can be stacked and stored.

In addition, the outer box 18 is not limited to the structure shown in FIG. 2, Any structure may be sufficient as long as the ceiling part 14 and the bottom part 16 become a double structure.
