DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a paper container, for example, a packaging container made of precious metal such as a watch or a jewelry, in particular, two strip-shaped blank paperboards, and is easy to assemble and develop by means of engraved grooves. The present invention relates to a paper container that can be used.

[0002]

2. Description of the Related Art FIG.
B, a first blank paperboard in which a first faceplate, a second faceplate, a third faceplate, and a fourth faceplate are longitudinally coupled in a strip shape through a laterally engraved groove is formed. Forming two continuous grooves along the left and right ears of the third and fourth face plates in the longitudinal direction of the first blank paperboard, and preparing the other two face plates, each lower portion of the two face plates. The edges are engaged in the respective vertical engraving grooves of the fourth face plate and are erected in an opposed state, and further, the first and second edges of the first face plate are provided with three first and second edges, respectively. Second
While covering the third face plate, the first, second and second
Bottom edges and rising edges of the two face plates are engaged with the adhesive injected into each of the vertical notches of the third face plate by using the adhesive injected into the vertical notches of the third and fourth face plates. The paper container shown in FIG. 3 is bonded to one of the two to form an integral structure.

[0003]

The above-mentioned paper container has an advantage that the products in the container can be viewed by opening the first and second face plates of the strip-shaped blank paperboard, and can be brought as a storage container after purchase. Since it is assembled into a box-shaped rigid structure during manufacturing, it has the problem of occupying excessive space for transportation from the factory to the user or storage in warehouses and sales floors, and therefore has the problem of high transportation costs. ing.

[0004] Further, when the adhesive material enters the edges of the two face plates, it overflows from the groove to impair the appearance, and conversely, the face plates are liable to come off due to insufficient bonding.

[0005] In addition, since the three-part structure and the above-mentioned engraved groove bonding structure are employed, it takes time and labor to assemble.

[0006]
