[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid paper container for storing beverages such as milk and juice.

[0002]

2. Description of the Related Art Conventionally, for a small capacity of about 200 cc to 350 cc, as shown in FIG. 5, the top and bottom surfaces of a prismatic container packaging material 1 are made flat so that Both end portions 3 of the upper seal portion 2 are respectively connected to the container side wall surface 4
Although not shown, a liquid paper container 5 called a block-shaped brick pack in which both ends of the lower seal portion are folded back on the bottom surface is used (not shown).
Then, the straw insertion hole 6 was provided in the corner of the top surface.

[0003]

However, in the above-mentioned conventional liquid paper container, the front and rear surfaces of the container are pinched and supported at the time of drinking, or the corners indicated by the arrow A are pinched and supported. The container itself is easily crushed, and when the container is pushed and deformed, the contents pop out from the straw insertion hole or the straw, which may stain hands or clothes.

In view of the above circumstances, it is an object of the present invention to make it possible to support the container without sandwiching the body of the container, which is likely to be deformed, and to facilitate the handling of the container during drinking. With the goal.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and is a block-shaped liquid paper container in which both ends of the upper sealing portion of the container packaging material are bent toward the side wall surface of the container. , A reverse end that releasably adheres the tip of the end portion of the upper seal portion to the container side wall surface, and regulates the opening degree of the end portion of the upper seal portion at the folded portion extending from the end portion of the upper seal portion to the container side wall surface. A liquid paper container provided with a bend prevention seal is provided to solve the above problems.

[0006]

In the present invention, both ends of the upper seal portion are peeled off from the side wall surface of the container and protruded to the side, so that both ends serve as fingers and the container is hung on the fingertips. Be able to support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. It should be noted that the same parts as those of the conventional example shown in FIG. That is, in the present invention, as shown in FIG. 1, the tip 30 of the end portion 3 of the upper seal portion 2 is releasably adhered to the container side wall surface 4 via the temporary adhesive s, and the end portion A reverse bending prevention seal 8 is attached to the folded portion 7 extending from 3 to the container side wall surface 4. Although only one end is shown in FIG. 1, the other end also has the same configuration.

The reverse-bending prevention seal 8 restricts the upward rotation of the end portion 3 after the end portion 3 is peeled off from the container side wall surface 4, and as shown in FIG. The end portion 3 is supported so that it does not bend upwards more than when it is horizontally projected. The seal 8 may have a relatively high rigidity, for example, so that the curved portion of the seal 8 does not extend so that the seal 8 does not open upward by more than about 90 °. Further, the seal 8 is made relatively soft as shown in FIG. 3, and both ends thereof are adhered and fixed to the end portion 3 and the container side wall surface 4 so that the hypotenuse portion can be formed, so that the seal 8 is bulged to the side. The end 3 may be supported.

Since each of the end portions 3 does not bend backwards upward as described above, it can be used as a handle for hanging a finger as shown in FIG. It will be able to support without applying pressure.

[0010]

As described above, according to the present invention,
The liquid paper container is a block-shaped one in which both ends of the upper sealing portion of the container packaging material are bent toward the side wall surface of the container, and the tip of the end portion of the upper sealing portion is releasably adhered to the side wall surface of the container. Moreover, since a reverse bending prevention seal for restricting the opening degree of the upper seal end portion is provided at the folded portion extending from the upper seal portion end portion to the container side wall surface, each end portion is said to jut out laterally when drinking. With a simple operation, the container can be supported without applying pressure, and it is possible to prevent the contents from popping out, which was apt to occur in the past.
