PACKAGING CONTAINER

PROBLEM TO BE SOLVED: To provide a packaging container capable of reducing a used material such as cardboard and capable of being assembled without using an adhesive agent. SOLUTION: In square cardboard materials 10 and 20 slightly larger than the outer diameter of an annular fluorescent lamp 1 serving as an object to be packaged, locking parts 11a to 11d and 21a to 21d for retaining the outside of the annular fluorescent lamp 1 are formed by cutting and raising. In the center parts of the locking parts 11a to 11d of the cardboard material 10, slits 12a to 12d for fitting with the other cardboard material 20 are formed, respectively. Meanwhile, in the locking parts 21a to 21d of the cardboard material 20, projections 22a to 22d for insertion into and coupling with the slits 12a to 12d are provided, respectively. The annular fluorescent lamp 1 is clamped by the cardboard materials 10 and 20, and the locking parts 11a to 11d and the locking parts 21a to 21d are coupled with each other. As a result, the annular fluorescent lamp 1 can be packaged without using any adhesive and with a small amount of the used material. COPYRIGHT: (C)2010,JPO&INPIT
