であった。2. Description of the Related Art Conventionally, in this type of liquid container, the crown portion or the bottom portion forms a thick layer by stacking or gathering folding pieces, so that a pulling force acts on the outer layer during bending work. There is a risk of damaging the coated part. Further, since a part of the cut edge is exposed to the inside of the container, there is a possibility that the liquid may permeate from the cut edge and lose its shape or leak. Therefore, in order to prevent liquid leakage of the liquid container, a lid structure for the liquid container of JP-A-63-96023, in which a pair of barrier layers are provided on opposite sides,
Japanese Patent Laid-Open No. 1-19 which suppresses the thickness of superposed parts of thick paper

きる。The long side panel and the short side panel, which are alternately continuous in the lateral direction, are bent to form a tubular body having a rectangular cross section. The folding flaps of the pair of long side panels in this rectangular tubular body are both folded back and forth inward. At this time, in the inner flaps of the opposing long side panels, the triangular portion and the outer side piece at the time of stacking abut against each other at the center, and the triangular portion is folded back on the inner side piece at the time of stacking. At this time, since inverted triangular notches are formed on both sides of the triangular portion, the triangular portion can be easily folded back and polymerization can be avoided. On the other hand, when the outer flaps are folded (outwardly) as outer flaps, the outer flaps are folded along a triangular or trapezoidal fold line and folded back into a triangular or trapezoidal shape. Since they overlap each other on the shape portion and have the same base angle on both sides, the tip of the outer flap invades and overlaps with the folded portion of the inner flap. At this time, if the top residual portion is formed, the triangular portion is double-folded at the end portion of the folded side when folded back, so that the sealing performance can be further improved.

9b is a mountain fold line 11, and the inner flap 9 is a mountain fold line 13
The outer flap 10 is folded along the mountain fold line 18 and overlapped to form the bottom of the square tube. In this case, when folding the inner flaps 9, 9 from both sides along their trapezoidal fold lines (valley fold lines 12 and 15), as shown in FIG.
As shown in FIG.
And the triangular portion B is folded back onto the inner piece A during polymerization. At this time, the adjacent folded-back portions D are pulled together, but the pair of notches C are combined to form the triangular portion B.
Since the voids that can be fitted in without substantially overlapping each other are formed without overlapping, the folded triangular portions B are double folded in the same flap 9 and no step is formed.

1 is folded up, and the outer flaps 10 and 10 that are pulled together in accordance with this will fall toward each other inwardly, so that at the time of folding, the triangular flap A pushes the triangular flap A toward the folding side by colliding with the triangular flap A at the center. Can be bent. Then, as shown in FIG. 3, the trapezoidal upper side portion on the other side is overlapped with the triangular portion B of the inner flap 9 that is folded first by an amount set to be longer than the height H2 of the height H1, These outer flaps 10, 10 are superposed from both sides with their tip lines in the center without a gap.

Since the upper hatch line display part) is all on the upper layer,
This end is not exposed inside the container, and the number of stacked paper pieces (the number of stacked layers) in the bottom forming area is uniform over the entire bottom surface, so that the bottom surface can be formed flat. In order to prevent contact between the cut end and the contents of the container, the upper side of the joining flap 6 of the inner flap 9 and the tip of the outer side piece E at the time of superposition may be restricted to the height H1, and may be inclined or stepped. It may be formed in various shapes such as.

In this case, the facing long side panel 1 is not an end portion of the paperboard but a midway portion and no joint portion is formed, so that it is not necessary to form the stacking outer side piece E formed in the long side panel 1 in a ladder shape. The folding line 12 may be formed so as to form a triangle with the center of the tip of the paperboard as the apex. The rest of the configuration is similar to that of the first embodiment, so its explanation is omitted.

It is cut away except the formed top remaining portion F, and a V-shaped fold line is formed on the top remaining portion F along the triangle. Here, the top residual portion F is formed in an arc shape whose tip edges contact the folding lines 16 and 17, respectively.

It is preferable because the sealing performance at both ends of the bottom of the shaped portion can be further improved. Since other configurations are the same as those of the first and second embodiments,
The description is omitted. Further, in the illustrated embodiment of the present invention, a known gable-type sealing structure is illustrated for the container crown portion,
It goes without saying that this crown portion may be configured to have the above-mentioned bottom structure. In the present invention, what is stored in these containers is not limited to liquids, and the same applies to fluids such as powders, granules, and gases.

部が容器内に露出しないようにしているので、液漏れを
防止することができ信頼性に優れる。As described above, according to the present invention, the work of bending the crown or the bottom of the fluid container can be facilitated. Further, since the number of flap paper pieces to be stacked can be reduced, the thickness of the overlapping portion can be suppressed and the flatness can be set, and the pulling force can be prevented from acting on the outer layer during the folding operation. Furthermore, since the cut edge of the closing flap that closes the crown or bottom of the fluid container is not exposed in the container, liquid leakage can be prevented and reliability is excellent.
