The present invention relates to a paper box for packaging used to package powder or granular solid detergents. In particular, the present invention relates to a watertight band formed in a band shape in the upper and lower corners of the upper and lower open ends of the box. The present invention relates to a packaging paper box molding apparatus and a molding method thereof having a function of preventing the loss of detergent so that a detergent or the like does not leak out even if a part of the box is deformed due to careless handling.

In general, the normal packaging paper box used to package the solid detergent, etc., considering the shelf life of the product and the period of use of the consumer should be able to be stored for a long time, so durability and water tightness are urgently required. .

This is because the solid detergent packaged in the box is made of fine particles, and has a property of being easily cured when air or moisture penetrates from the outside.

In addition, when an impact is applied to the magnetic field from the outside during the transportation or distribution process, a gap occurs at the corners of the box due to the impact, and thus, the contents of the package are spilled out frequently. I'm doing it.

Such a conventional box body also has an integrally formed tare tape part on the upper part of the box body so that the lid part can be easily opened. Since such a tape is formed by being subjected to a sanding process on the upper surface member of the box body, the processing is performed. External air or moisture is easily penetrated through the site, and in this case, the curing of the solid detergent, which is packaged in the box, is more rapidly occurring.

Therefore, when the packaging paper box is constructed, more precise edge processing is required, and the inner surface of the paper box inserts an inlet to enhance the durability of the box and effectively block the inflow of external air. In-Let is inserted in this way, all of which is inserted in the form covering all the inner surface of the box, resulting in unnecessary weight increase, as well as requiring a separate process for fixing the inlet It was to cause the degradation of.
