[Problems to be solved by the device]

 In the conventional paper pack container as described above, when the contents are to be cut out, it is necessary to peel off the triangular portion c attached to the side surface of the container a and then cut it off along the cutting line with scissors. Therefore, a tool called scissors is always required for the opening, and there is a disadvantage that the container cannot be opened without preparing scissors.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above problems and provide a paper pack container that can be opened without using tools such as scissors.

[Means for Solving the Problems]

 In view of the above object, the present invention solves the above problem by providing an unbonded opening piece on the extension of the sealing portion on the upper part of the container.

Hereinafter, the present invention will be described in detail with reference to the drawings. 1 to 4, reference numerals 1, 2, 3 and 4 are side walls forming side surfaces of a container, 5 is a top portion of the container, 6 is a seal portion provided on the top portion 5, and 7 is a tip portion from the seal portion 6 of the top portion 5. It is an opening piece provided. The top portion 5 has extension portions 5a and 5b on both sides, the seal portion 6 has extension portions 6a and 6b on both sides, and the opening piece 7 has extension portions 7a and 7b on both sides. The extensions 5a, 5b, 6a, 6b, 7a, 7b are both bent downward and bonded to the side walls 3 and 4 of the container, respectively.

As shown in FIG. 4, after the container is filled with the contents, the opening is sealed by the seal portion 6, and the opening piece 7 is located at the tip of the seal portion 6. Then, the end portion of the opening piece 7 is in a state of being cut off as shown in FIG. In this state, as shown in FIG. 1, the opening piece 7 is first laid down on the side wall 2 side to form a flat upper surface together with the top 5 of the container, and then the extension portions on both sides are bent downward to form the side wall 3 respectively. , 4 with each extension bonded.

In the case of opening, first, the extension portions 5a, 6a, 7a and 5b, 6b, 7b are peeled off from the side walls 3 and 4, and then the opening piece 7 is pulled up to a state shown in FIG. And In this state, when the front end 7c, which is not adhered at the end and is open, is opened in both directions with a fingertip in the direction indicated by the arrow (see FIG. 5), the seal portion 6 separates and the top of the container is opened. The opening piece 7 may be provided at an arbitrary width and position at the tip of the seal portion 6 by appropriately cutting it off. The point is that an opening piece 7 that can be opened with a fingertip should be provided somewhere on the tip of the seal portion 6.
