DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

The present invention discloses a partial reinforcement packing structure to ensure the strength of packing without increasing the thickness of packing. The present invention comprises wall portions and corner portions formed between adjacent two of the wall portions. The wall portions or the corner portions are provided with reinforcement strips.

In the same conditions, a thin (or lower-weight) material replaces a thick (or high-weight) material to meet the technical requirements of product packing, lower production costs, and enhance comprehensive benefits.

As shown in FIG. 1 to FIG. 7, the packing structure according to a preferred embodiment of the present invention comprises a bottom wall 11, a top wall 12 and a side wall. The side wall includes a left side wall 13, a right side wall 14, a front side wall 15, and a rear side wall 16 which are integrally formed. The reinforcement strips extend from the bottom wall 11 to the side wall and extends from the side wall to the top wall 12. The reinforcement strips include a left reinforcement strip 31, a right reinforcement strip 32, a front reinforcement strip 33, and a rear reinforcement strip 34. The left reinforcement strip 31 and the right reinforcement strip 32 are disposed symmetrically. The front reinforcement strip 33 and the rear reinforcement strip 34 are disposed symmetrically. The left reinforcement strip 31 extends from the bottom wall 11 to the left side wall 13 and extends from the left side wall 13 to the top wall 12. The right reinforcement strip 32 extends from the bottom wall 11 to the right side wall 14 and extends from the right side wall 14 to the top wall 12. The rear reinforcement strip 34 extends from a middle portion of the top wall 12 to the rear side wall 16 and extends from the rear side wall 16 to the bottom wall 11. The front reinforcement strip 33 extends from the middle portion of the top wall 12 to the front side wall 15 and extends from the front side wall 15 to the bottom wall 11. The integrity of the packing structure is better. The packing structure has more strength to get significant compression resistance and burst index.

As shown in FIG. 8 to FIG. 14, the reinforcement strips can be L-shaped reinforcement strips 35 to match with the corner portions 20. Two sides of each L-shaped reinforcement strip 35 are disposed on two adjacent wall portions of the corresponding corner portion 20. Preferably, the wall portions are four side walls including the left side wall 13, the right side wall 14, the front side wall 15, and the rear side wall 16. The L-shaped reinforcement strips 35 are disposed on four corner portions 20 each formed between adjacent two of the side walls, such that the packing structure won't be pressed easily in the height direction so as to provide better strength.

As shown in FIG. 6 and FIG. 13, the folding process of the reinforcement strip is described hereinafter. Two sides of a cardboard or a piece of paper are moved inward, and the central portion of the cardboard or the piece of paper is formed with a raised portion. The raised portion is compressed by the force, and the raised portion is adhered to the lower side of the cardboard or the piece of paper by means of glue or nails.

Preferably, the packing structure adopts a sheet of cardboard or paper to form an integral cardboard box, carton, or paper bag through die cutting and folding. The reinforcement strips are adhered to the wall portions or the corner portions by means of glue or nails. FIG. 5 and FIG. 12 are schematic views to show the unfolded configuration of the present invention. The reinforcement strips of the cardboard of the piece of water are first secured, and pressed longitudinally for cutting lines, and then cut transversely to form a box body. When folded, four sides of the middle portion of the box body constitute the left side wall 13, the right side wall 14, the front side wall 15, and the rear side wall 16 of the box, and then the tabs at the sides thereof are bent inward to form the bottom wall 11 and the top wall 12.

By using the present invention, such as cardboard boxes, the investment in the production line for three-layer cardboards or five-layer cardboards can be reduced at least 35%. In the same conditions, through the aforesaid reinforcement strips, a three-layer cardboard (or low-weight material) according to the packing requirements of different products can replace a five-layer cardboard (or high-weight material) used for the majority of small and medium boxes (cases) to meet the packing requirements of different products. On the premise that the packing material and size are constant, the present invention can significantly enhance the compression resistance and burst index of packing, alternatively, on the premise that the compression resistance and burst index of packing are constant, a thin material can replace a thick material. The present invention can avoid excessive packaging, reduce material waste, lower production costs, and enhance the comprehensive benefits.

Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
