With this configuration, when the paper containers are stacked in multiple stages, the bottom portion of the upper paper container does not hit the end wall provided with the first and second half cuts of the lower paper container, so that transportation is performed. There is no risk that the first and second half cuts will be damaged even if they are stacked in multiple stages along the way. In addition, since the end of the second half-cut, which is a clue for peeling, is provided slightly protruding from the horizontal crease forming the lower edge of the end wall toward the body, the process of forming the paper container from the paperboard substrate is performed. Then, the portion protruding from the lateral crease to the body portion side is separated from the body portion and floats up, and by picking up the floating piece, the portion surrounded by the second half cut can be easily peeled off. The opening of the straw mouth is facilitated.

In the second half cut,
An end serving as a clue for the peeling is provided so as to be located diagonally below the first half cut position, and the second half cut is provided so as to be peelable diagonally upward toward the first half cut position. Good to be.

In this manner, when the portion surrounded by the second half cut is peeled to open the straw opening,
Since the direction of picking the end which is the clue of peeling is obliquely upward toward the first half cut position, the finger does not hit the hypotenuse of the gable roof surface at the top of the gable roof type at the time of peeling,
The peeling operation can be easily performed, and the opening of the straw opening is further facilitated.

[0009] The end of the second half-cut, which is provided so as to be obliquely below the first half-cut position, is a virtual vertical line passing through the center of the portion surrounded by the first half-cut. It may be provided on each of the left and right sides of the line.

In this way, the right-handed person and the left-handed person can easily peel off the portion surrounded by the second half-cut, and the opening of the straw opening becomes easier.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 3 show an embodiment of a paper container according to the present invention. The paper container 1 shown in FIG. 1 is formed by a paperboard substrate 6 whose front and back surfaces are coated with a thermoplastic resin. It is formed by sealing the lower part of the rectangular cylindrical body 9 flat and closing the bottom part, filling it with a liquid such as a beverage, and then sealing the upper part with a gable roof type. This is a so-called goebel top type paper container.

The gable roof 3 of the gable roof type top 2 of the paper container 1
And the first half cut 4 which becomes a straw mouth from the back
Is provided, and a second half cut 5 is provided so as to surround the first half cut 4 from the surface thereof.
The first half cut 4 and the second half cut 5 both reach the paper layer of the paperboard substrate 6.

An end 7 serving as a clue for peeling off the second half cut 5 is provided slightly protruding from the horizontal crease 8 forming the lower end edge of the end wall 3 to the body 9. The length L of the end 7 of the second half cut 5 projecting from the lateral crease 8 to the body 9 is determined in a range of 0.3 mm to 3.0 mm. When the length L is 0.3 mm or less, when peeling a portion surrounded by a second half cut 5 described later,
It is difficult to pick up a floating piece formed by the end portion 7 serving as a clue. On the other hand, when the length is 3.0 mm or more, the end portion 7 is hardly lifted from the body portion 9 when the paper container 1 is formed. The shape of the end 7 of the second half cut 5 protruding from the lateral crease 8 to the body 9 has a protruding length L of 0.3 mm or more.
There is no particular limitation as long as it is within the range of 3.0 mm. In this example, the end 7 serving as a clue for peeling the second half cut 5 is provided so as to be positioned diagonally below the position of the first half cut 4. Is detachably provided diagonally upward from the end 7 toward the position of the first half cut 4. This peeling direction corresponds to the inclination angle of the oblique side of the gable roof surface of the gable roof type top 2, and in this example, it is approximately 4 with respect to the vertical direction.
The direction is 5 degrees. The shape of the line of the second half cut 5, which enables the peeling diagonally upward, may be a straight line or a curve as long as the line does not affect the peeling operation.

According to the paper container 1 constructed as described above, the first half cut 4 and the second half cut 4 opening the straw opening are provided.
Since the half cut 5 is provided on the wall 3 of the gable roof type top 2, for example, when the paper containers 1 are stacked in multiple stages, the bottom of the paper container 1 in the upper stage becomes the gable roof type top of the paper container 1 in the lower stage. Since the paper container 1 is placed on the gabled roof surface and does not hit the wife wall 3, even if the paper containers 1 are stacked in multiple stages during transportation, the paper container 1 is provided on the wife wall 3 of the lower paper container 1 by the bottom of the upper paper container 1. The first half cut 4 and the second half cut 5 are not damaged, and can be transported in a perfect state.

In the second half cut 5, an end portion 7 serving as a clue for peeling is provided so as to slightly protrude from the horizontal crease 8 forming the lower end edge of the end wall 3 to the body portion 9. Therefore, in the process of forming the paper container 1 from the paperboard substrate 6, when the horizontal crease 8 is bent, a portion projecting from the horizontal crease 8 toward the body 9 is delaminated from the body 9 and floats. By climbing and picking up the floating piece 10, the portion surrounded by the second half cut 5 can be easily peeled off.

When the delamination of the portion surrounded by the second half cut 5 reaches the first half cut 4, the portion surrounded by the first half cut 4 becomes the second half cut 5.
The straw piece 12 is cut off by the peeling piece 11 to open the straw opening 12 (FIG. 3).

The end 7 serving as a clue for peeling the second half cut 5 is provided so as to be located diagonally below the position of the first half cut 4. 2 The part surrounded by the half cut 5 is the end 7
Is provided so as to be able to be peeled diagonally upward from the first half cut 4 to the position of the first half cut 4, so that the end 7 is picked when peeling off the portion surrounded by the second half cut 5 for opening the straw opening. The finger does not hit the oblique side of the gable roof surface of the gable roof type top 2 and can be peeled without being restricted by its operation. Therefore, the peeling operation is facilitated, and the opening of the straw opening can be easily performed.

FIGS. 4 and 5 show other examples of the embodiment of the present invention. In this example, an end 7 serving as a clue for peeling off the second half cut 5 is surrounded by the first half cut 4. The left and right sides of an imaginary vertical line passing through the center of the cut portion are provided so as to be positioned obliquely below the position of the first half cut 4, respectively. The second half cut 5 is provided such that a portion surrounded by the second half cut 5 can be peeled diagonally upward from any of the end portions 7 provided on the left and right toward the position of the first half cut 4. Have been.
