 The present invention relates to a liquid bag-in-box in which an inner bag with a spout is housed in an outer box.In particular, the spout of the inner bag is easy to take out, and the spout is likely to collapse during use. No, it concerns a liquid bag-in-box.

[0002]

[Prior art]

 A so-called bag-in-box in which an inner bag with an outlet is stored in an outer box is used as a container for storing a large amount of liquid such as soy sauce, juice, and sauce. Before this bag-in-box, the spout was housed in an outer box, and the spout was taken out of the outer box and the liquid was poured out during use. In order to take out the spout out of the outer box, the outer box is provided with a spout fixing portion 12 consisting of a circular cutting line 5 as shown in FIG. An opening portion 21 is provided which comprises a cutting line 16 and folding lines 19 and 20 connecting both ends 17 and 18 of the cutting line 16 and both sides of the fixed portion 12.

When removing the spout 12, as shown in FIG. 7, a circular cutting line is cut to form the fixing portion 12, and then the T-shaped cutting line 16 is broken, and Opening pieces 32 and 33 are opened to the left and right to form opening 31. The spout 30 of the inner bag is pulled out by inserting a hand into the opening 31. As shown in FIG. 8, the spout 30 thus drawn out has the fixing part 12 formed by returning the two opening pieces 32 and 33 of the opening 31 to the original state, thereby fixing the spout 30. .

[0004] As shown in FIG. 9, the shape of the opening scheduled portion 11 is a fixed portion 12 formed from a circular cutting line, and the opening cutting lines 6 and 7 extending from the fixed portion 12 to both sides, and There is a structure having a folding line 10 connecting both ends 8 and 9 of the opening cutting lines 6 and 7.

[0005] As shown in FIG. 10, the opening portion is formed by cutting the circular fixing portion 12, then breaking the opening cutting lines 6 and 7, and pulling the opening piece 14 upward to form the opening portion 13. Then, a hand is put into the opening, the spout 12 is taken out, and the opening piece 13 is returned to the original state, and the fixing portion 12 is formed as shown in FIG. 11 to fix the spout 30.

[0006]

[Problems to be solved by the invention]

 The planned opening of the structure shown in FIG. 6 requires a certain length of the outer fluff in order to make it easy to take out the spout. It was difficult to enter and there was a risk that the function would be insufficient.

On the other hand, in the planned opening portion of the structure shown in FIG. 9, an opening having a certain area or more can be formed by extending the opening cutting line in the horizontal direction. It was easy to take out the spout. However, after the spout was taken out, the spout could fall inward during use with the spout fixed to the fixed part.

An object of the present invention is to provide an opening having a certain area even when the length of the outer flap is short, and to prevent the spout from dropping inward during use. An object of the present invention is to provide a liquid bag-in-box having the formed outer box.

[0009]

[Means for Solving the Problems]

 According to the present invention, the inner bag with the spout is provided with a pair of inner flaps on the left and right sides and an opening flap surrounded by a cutting line for taking out the spout on one outer flap. Further, in the liquid bag-in-box housed in an outer box having a pair of front and rear outer flaps, the front ends of the pair of inner flaps extend inward from both side ends of a cutting line at a portion to be opened. A liquid bag-in-box, characterized in that:

[0010] A second invention is a liquid bag-in-box in which the opening scheduled portion has a horizontally long shape. A third aspect of the present invention is a liquid bag inbox in which the portion to be opened is sized to be accessible. A fourth aspect of the present invention is a liquid bag inbox in which the expected opening portion is formed by a spout fixing portion having a periphery formed by a cutting line, and an opening cutting line extending to both sides from the spout fixing portion. According to a fifth aspect of the present invention, an opening fixed portion is formed by a spout fixing portion including a cutting line, a T-shaped opening cutting line above the spout fixing portion, and both ends of the opening cutting line and the spout. This is a liquid bag-in-box formed from a fold line connecting the side of the fixing portion.

[0011]

[Embodiment of the invention]

 FIG. 1 is an explanatory view of a blank of the outer box 1, in which four side walls 2 A, 2 B, 2 C, and 2 D forming a body 2, and four bottoms are formed from the four side walls via ruled lines. On the walls 3A, 3B, 3C, 3D and above, similarly through the ruled lines, the side walls 2B, 2D are provided with inner fluffs 4B, 4D, and the side walls 2A, 2C are provided with outer fluffs 4A, 4C. It consists of the installed configuration.

Here, each of the inner flaps 4B and 4D has a shorter length on the outer flap 4C side. The outer flap 4C has a spout fixing portion 12 having a circular cutting line 5 at the center, opening cutting lines 6 and 7 extending to both sides of the fixing portion 5, and both ends 8 of the opening cutting lines 6 and 7. , 9 is provided with a scheduled opening portion 11 consisting of a folding line 10.

The lengths X 1 and X 2 of the short portions of the inner flaps 4 B and 4 D are formed to be longer than the distances Y 1 and Y 2 from both sides of the outer flap 4 C to both ends of the folding line 10. The lengths of the inner flaps 4B and 4D are not necessarily the same, and one of them may be formed to be longer. Further, the outer flaps 4A and 4C do not necessarily have to be the same length, but it is preferable that the ends thereof abut when assembled. The above-mentioned cutting lines 5, 6 and 7 suitably have a so-called perforated structure provided intermittently, and the folding line 10 is a pressing ruled line or a half-cut line.

When the blank shown in FIG. 1 is assembled, as shown in FIG. 2, the expected opening 11 provided on the outer flap 4C is located at the short side of the inner flaps 4A and 4B facing each other. The ends of the flaps 4B, 4D have a structure extending inward from both sides of the planned opening portion 11.

As shown in FIG. 3, the cutting line 5 and the opening cutting lines 6 and 7 are broken, the opening piece 14 is caused, and the opening 13 is formed. Pull out the spout 30. Next, as shown in FIG. 4, the opening piece 14 is returned to its original position, the fixing portion 12 is formed, and the spout 30 is fixed.

Here, the lengths X1 and X2 of the short portions of the inner flaps 4B and 4D are formed so as to be longer than the distances Y1 and Y2 from both sides of the outer flap 4C to both ends of the folding line 10. By assembling, the shape of the scheduled opening portion 11 can be enlarged horizontally and even if the spout is taken out and fixed to the fixing portion, the opening piece 14 is supported by the inner flaps 4B and 4D, and the spout is in use. It can prevent falling. In addition to the shape shown in FIG. 1, as shown in FIG. 5, the shape of the scheduled opening portion 11 is, as shown in FIG. In addition, a T-shaped opening cutting line 16 and a scheduled opening portion 21 having folding lines 19 and 20 connecting both ends 17 and 18 of the opening cutting line 16 and both sides of the fixed portion are provided.

[0017]

[Effect of the invention]

 At this time, the length of the short portion of the inner flaps 4B and 4D is equal to the distance from both sides of the outer flap 4C to both ends of the planned opening 11 irrespective of the shape of the planned opening 11. What is necessary is just to form so that it may become longer.

In the present invention, since the opening can be made large in this way, it is easy to access during use, and the work of taking out the spout and fixing the spout to the fixing portion can be easily performed. Also, the length of the short portion of the inner flap was formed so as to be longer than the distance from both sides of the outer flap forming the planned opening portion to both ends of the planned opening portion 11, so that when the outer box was assembled, it was opened. Since both ends of the opening piece are supported by the inner flap, there is no danger that the spout will fall down during use, and it can be used with confidence. Furthermore, even if the length of the outer flap is shortened, an opening having a sufficient area can be formed, the shape of the outer box is reduced, and the outer flap is sealed not only by gluing but also by adhesive tape from the outside. It is also possible to seal using.
