a paper container

technical field

The invention relates to a paper container suitable for placing detergent.

Background technique

Considering that it can be incinerated during disposal, the detergent container is made of paper container. Japanese Patent No. 2656903 discloses a paper container in which the opening of the box is covered by a top cover, and the adhesive sealing strip extending along the side surface of the top cover is torn off from the outer surface of the side wall of the box to open the top cover. Also tear off the snap tongue member attached to the outer side of the open side portion of the case to stand upright. When the top cover is closed, the engaging recessed portion provided inside the top cover can be engaged with the engaging tongue member erected in the above-mentioned manner. Therefore, gaps in the opening direction of the top cover from the closed position can be prevented, which prevents the detergent from absorbing moisture and hardening.

The detergent container described above has the following problems.

1) When the snap tongue part connected to the outer side of the box is torn off, the appearance of the box will be unattractive due to the traces of tearing.

2) The strength between the box body and the snap tongue is reduced by tearing off the snap tongue.

3) The upright snap tongue part has a tendency to return to the outer surface of the box that it was connected to before being upright. This action forms a disengagement force that allows the top cover to leave the recessed part, thus reducing the locking of the top cover. The reliability makes the detergent easy to absorb moisture.

4) When the adhesive sealing strip provided on the top cover is torn off, its front surface layer still remains on the side wall of the box body. The adhesive sealing strip is torn between layers, and the torn middle layer extends over a large area on the top cover, which reduces the strength of the top cover.
