A durable paper box formed from a foldable cardboard comprising a center, a front wall including a forward extension and two first enhancement elements at both sides of the forward extension, a rear wall, two side walls each including a side extension, two folded members formed between the rear wall and either side wall and coupled thereto, and two second enhancement elements formed between the front wall and either side wall and coupled thereto. The paper box is formed by folding the cardboard with the second enhancement elements being sandwiched by the front wall and the forward extension at two front corners of the paper box and either first enhancement element being sandwiched by the side wall and the side extension at either front corner of the paper box.
The present invention relates to paper boxes and more particularly to a paper box from a piece of cardboard with enhanced elements by folding so that the formed paper box has added structural strength so as to be durable.
BACKGROUND OF THE INVENTION A conventional paper box 10 formed by folding a piece of cardboard is shown in FIGS. 1 to 4. As shown in an extended plan view of the piece of cardboard, it comprises a rectangular center 20, four four-sided walls 30 extending from four sides of the center 20, two folds 40 each extending from one side of two opposite side walls 30, and two rectangular enhancement elements 50 each formed between the front wall 30 and either side wall 30 and coupled thereto. The enhancement elements 50 are formed inside both ends of the front wall 30 after forming the paper box 10 by folding (see
It is an object of the present invention to provide a structurally strong paper box from a foldable cardboard including a rectangular center, a four-sided front wall extending from a front side of the center and bordered therewith, a four-sided rear wall extended from a rear side of the center and bordered therewith, and two side walls each extending from both sides of the center and bordered therewith. The front wall includes a four-sided forward extension bordered the front wall and two four-sided first enhancement elements extending from either side of the forward extension. Each side wall includes a side extension bordered the side wall. Two four-sided folded members are formed respectively between the rear wall and either side wall and coupled thereto. And two second enhancement elements are formed respectively between the front wall and either side wall and coupled thereto. In assembly, fold the cardboard to form a paper box with the second enhancement elements being sandwiched by the front wall and the forward extension at two front corners of the paper box and either first enhancement element being sandwiched by the side wall and the side extension at either front corner of the paper box.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
