Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is such that when a box made of board material is assembled, a right-angled corner iron bar can be held and fixed by an edge frame at the open edge portions on four sides.

It is installed in a box edge frame system that strengthens the opening corner and fixes the DrI corner to maintain rigid frame strength (shape strength).

Conventionally, containers and trays made of board materials such as fibers and synthetic resins have weak opening edges and some corners, and their rigid frame strength is weak, making it difficult to make strong boxes.

In particular, it was difficult to maintain the strength of the rigid frame when using the knockdown type or cooking type.Meanwhile, edge frames for edge reinforcement were attached to the four sides of the opening edge of one box, and the edge frame was used to create an abbreviated shape. Some synthetic resin corner members were installed to reinforce the corners, but the strength of the rigid frame was insufficient unless caulked.

An object of the present invention is to be able to reinforce the opening edges of boxes made of boat wood, fix the opening corners of five boxes at right angles, maintain rigid frame strength, and make knock-down boxes and squares. You can easily assemble cooking-type boxes, etc.

Our goal is to provide an edge frame system that is beautiful, strong, and convenient.

In order to achieve such an object, the present invention makes it possible to wrap and fix a right-angled corner iron bar with an edge frame that is secured to the four sides of the opening edge when a box made of board material is assembled. This allows the edges and opening corners to be reinforced.
