Packaging box structure and packaging box folding method

The present invention relates to a package structure, and more particularly to a package structure that is simple in construction and saves material consumption.

Nowadays, the types, patterns and appearances of the packaging boxes are quite numerous, and there are many packaging group designs that can be combined without using glue or staples, but in order to keep the shape of the assembled package, such packaging is usually used. The box will be designed with a number of snap-on structures, which makes the package have a certain complexity in structure, and the steps in assembling the package are complicated, and the user is troubled in use.

Referring now to Figure 1, Figure 1 is a plan view of a prior art package structure. As shown in FIG. 1, the prior art package 90 includes a bottom plate 92 and side connecting plates 91 coupled to opposite sides of the bottom plate 92, wherein the connecting plate 91 includes two sub-joints 911, 912 having substantially the same width. When the prior art package 90 is assembled, the side web 91 is bent toward the bottom plate 92 while the sub-joint 911 covers the tab 912 to increase the stability of the side of the prior art package 90 after the prior art package 90 is formed.

As shown in Fig. 1, the cutting area of the prior art package structure 90 is determined by the plane width W1 (the widest width of the plane) and the plane length L1 (the longest plane length) after the package is unfolded. If the surface length L1 is not changed, if the cutting area is to be reduced, the width of the plane width W1 needs to be reduced. However, as described in the previous paragraph, if the plane width W1 is arbitrarily reduced, it is inevitable that the prior art package 90 is formed. The stability of the side of the prior art package 90.

Therefore, it is necessary to provide a new package structure, on the one hand, using less cutting area, while ensuring the stability of the side of the package 90 after the prior art package 90 is formed, and the overall structure is simple, simplifying the structure of the package. Combining time saves material and increases ease of use.

When the package structure of the present invention is folded into a package by a plane, the first bending piece contacts the inner side surface, the folding piece covers a portion of the first bending piece, and the second bending piece is folded toward the first bending piece. A portion of the folding member is sandwiched between the first bending piece and the second bending piece.

According to an embodiment of the invention, the inner side has a width d and the fold has a width d1, wherein the width d>d1.

According to an embodiment of the invention, each of the second side panels respectively includes a slot provided on the main body.

According to an embodiment of the invention, the other side of the second bent piece is provided with an ear portion, wherein the ear portion is engaged with the socket after the second bending piece is folded toward the main body.

According to an embodiment of the present invention, the second side panel includes a notch at the junction of the first bending piece and the second bending piece, and the folding piece is provided with at least a mouth, wherein the position of the notch and at least the mouth correspond.

According to an embodiment of the invention, the package further includes a cover plate including a third side edge and two oppositely disposed third bending pieces, wherein the third side edge and one of the two first side plates The edge is connected, and when the cover is bent toward the bottom plate, the lower edge of the third bent piece contacts the upper edge of the second bent piece.

According to an embodiment of the invention, the inner side surface has a width d, and when the lower edge of the third bending piece contacts the upper edge of the second bending piece, the width d2 of the third bending piece and the second bending piece are erected The sum of the widths is substantially equal to or smaller than the width d.

According to an embodiment of the invention, the package structure is made of a corrugated material.

The present invention further provides a packaging box folding method for folding the packaging box structure of the present invention. The folding method of the packaging box of the present invention comprises the steps of: bending the two first side panels and the two second side panels toward the bottom panel respectively, so that the first The bent piece contacts the inner side surface; the inner side surface folds the folding piece and covers a portion of the first bending piece; and the second bending piece is folded toward the second side plate, so that the partial folding piece is clamped to the first side Between a bent piece and the second bent piece.
