ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to a paperboard box with improved structure and, more specifically, to a paperboard box having pre-pierced holes through which the box is screwed and fastened, and thus the box can be easily assembled by users.
2. Description of the Prior Art
Heretofore, it is known to construct a paperboard box with two separate pieces of paperboard, with one board folded into the base and the other as the top lid. On each of these two paperboards, there are 2 vertical and 2 horizontal creases partitioning the paperboard into a top, a base and 4 sides(i.e., right, left, front and back). At the ends of the right, left, and front sides there are extended panels which, when the board is folded, are to be folded inwards and would stick together to secure the cube. The top lid and the base of the box are then put together with their open ends facing each other and are adhered to each other at one side of the open ends. An in-box frame is fitted into the base so that the box can tightly close.
The construction of such boxes typically requires specific glue to be applied to secure the cubes. The special equipment and techniques required for applying the glue would cause difficulties for users who wish to set up the boxes by themselves.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a paperboard box secured by screws and washers. A one-piece paperboard has 2 horizontal and 4 vertical creases, which partition the board into a top section and a base section, with each having a top/base and 4 sides (i.e., right, left, front and back). The back lateral is where these two sections connect. For both the top and the base sections, there are extended panels at the ends of the left and right sides. On the center of each panel there is a pre-pierced hole. When the box is folded into a cube, the panels are folded inwards, and on the front side and the back side corresponding to the holes of the panels there are also pierced holes. The pre-pierced holes are disposed on washers corresponding to the holes of the panels and the front sides. Through the holes, screws are used to secure the box. Finally, an in-box frame is fitted into the base of the box. This invention allows users to easily assemble boxes by themselves.
The above object, features and advantages of the present invention will become apparent from the following description when taken in conjunction with the accompanying drawings in which a preferred embodiment of the present invention is shown by way of illustrative example.
