Further, the contents that can be poured are used in powdered detergents, salt, rice, etc., in powder, granular and granular solids.

  Normally, this type of carton has a rectangular tube-shaped body part, which has good alignment and excellent transportability, but on the other hand, the strength of each side of the body is weak and the body bulge phenomenon There was also a phenomenon that caused the liquid to be accidentally ejected due to external pressure by fingers. In addition, the display at the time of sale generally has only one flat design part display, and there is a disadvantage that cannot be differentiated from a general paper box display. Further, at the time of use, it is hard to hold because it is angular, and troubles such as the corner portion biting into the fingers have occurred.

As a solution to the above problem, the body portion of the paper container is characterized by providing a predetermined crease that forms a recess with a certain shape in advance toward the inside of the container on the ridge line formed by each side wall. The proposed device is disclosed. This device is designed to prevent deformation such as dents caused by the reduced pressure accompanying cooling after filling and sealing at high temperature, but as shown in the embodiment, concave portions are formed at each corner. In this way, the appearance design is retained, and a practical effect is obtained in that the finger grip during use is good. However, this device is effective against decompression due to cooling. However, in a large-capacity paper container filled at room temperature, deterioration of the appearance design due to the swollen phenomenon is unavoidable, and the paper container of the present invention has an expanded body width.
