Description

[Detailed description of the invention] This invention relates to a container made by pasting an inner bag to the inner wall of an outer box made of paperboard, and its purpose is to obtain a container that is sturdy and easy to hold even when filled with liquid and stacked. That is.

Conventionally, containers of this type for filling liquids such as milk, alcohol, seasonings, etc. have a complicated structure because the adhesive part at the top of the container is partially peeled off to create a spout, and many boxes are stacked and transported. In addition, containers in the shape of a rectangular parallelepiped are difficult to hold because they do not catch fingers, and when a large number of containers are stacked on top of each other, the lower containers may collapse under the weight of the containers.

The present invention aims to eliminate these drawbacks and provide a container in which the amount of liquid remaining when pouring out the contents is reduced, and will be described below based on the embodiments shown in the drawings.

In the developed plan view of the outer box shown in FIG. 1, the side plates 5, 6, 7.8 and the adhesive plate 9 are connected to each other via vertical fold lines 1°2.3 and 4.

A transverse fold line 10 is provided at the lower end of the side plates 5, 6, 7.8, and a parallel transverse fold line'11.1 is provided at the upper end of the side plate 5, 7.
2, and a diagonal fold line 1' which is an extension of the vertical fold line.

A generally trapezoidal spout forming plate 13 surrounded by 2', 3', and 4' is provided in succession, and tongue pieces 14, 14' are provided in succession via a transverse fold line 11.10.

At the upper ends of the side plates 6 and 8, triangular folding plates 16 whose upper ends can be kept horizontal are arranged in series through diagonal folding lines 15 that are connected to the transverse folding lines 12 of the side plates 5 and 7. A lid piece 18 is inserted through the transverse fold line 17 and the transverse fold line 10 connecting the opposite corners.
, 19 are installed protrudingly.

Next, as shown in FIG. 2, the present invention incorporates an inner bag 20 inside the outer box.

The inner bag 20 is formed in any shape such as a cylindrical shape or an angular shape, and is bonded to at least the side plate of the outer box, at least the spout forming plate 13, with an adhesive.

To assemble the container of the present invention having the above configuration, the side plate 5,
6, 7.8 and the adhesive plate 9 along vertical fold lines 1, 2.3 and 4, respectively.
The adhesive plate 9 is superimposed on the inside of the side plate 5 by bending it at right angles inward along the side plate 5, and then the inner bag 20 is adhered to the inside, and then the lower end of the inner bag 20 is welded or the like. After closing, the tongue piece 14' of the opening at the lower end is bent inward at right angles, and then the lid piece 19 is bent and glued together to form the bottom part.

Furthermore, after filling the inner bag 20 with the liquid content, close the mouth of the inner bag 20, and then fold the spout forming plate 13 diagonally inward from the transverse fold line 12 while pushing the inner bag 20 inside. At the same time as bending, the folding plate 16 is also bent and pressed to the side plates 6 and 8, as shown in FIG. 3, and the tongue piece 14 is bent horizontally.

Similarly, after bending the other spout forming plate 13 and folding plate 16, the tongue piece 14 is bent and overlapped with the tongue piece 14 that was bent first (see FIG. 4).

Subsequently, the lid pieces 18 may be bent at right angles from the transverse fold line 17 and bonded together to form a seal.

(See Figure 5). When using the container of the present invention, it is sufficient to insert a well-known spout stopper into an appropriate location on the spout forming plate 13 until it reaches the inner bag 20 and pour out the liquid content, or pour it only into the outer box in advance. If the outlet X of the spout is left open or a perforation line X' for forming the outlet X is provided, the spout can be easily inserted.

Since the present invention has the above-mentioned configuration, even when a large number of containers are stacked on top of each other, the triangular folding plate 16 and the side plates 6, 8 are integrated to form a double wall, and the diagonal folding line 1', 2'
, 3' and 4' absorb the wall thickness of the double wall, and the side plates 6,
8 can be assembled vertically, so it has excellent load resistance and will not bulge or collapse even when stacked in large numbers.The upper part has a trapezoidal cross section, and the spout forming plate 13
Since the recess Y is formed by the folding plate 16 and the lid piece 18, the side plates do not come into close contact with each other when taking out the boxes that are arranged side by side, so it is not necessary to put your finger into the recess Y and hook it on the lid piece 18. This makes it easy to take out and convenient to carry.

Furthermore, since the present invention forms a recess Y, the spout can be housed in the recess Y, and in combination with the trapezoidal upper part, the spout plugs housed in the recess can be stored in parallel. It doesn't get in the way when you do it.

Furthermore, the present invention is not only easy to assemble, but also has the effect that the spout forming plate 13 has an inclined surface, so that there is less residual liquid and no waste.
