Description

Packing box

The present invention is related to packaging materials, in particular to a packaging box that can prevent the lid from being warped.

Figures 8 to 11 show a common packaging box 90 on the market, which includes a box body 91 and a box cover 92. The box body 91 includes a bottom surface 911 and four on the bottom surface 911. An accommodating space 913 surrounded by the side surface 912. The box body 91 has an opening 914 through which the accommodating space 913 can lead to the outside 93; the box cover 92 is arranged on one side of the box body 91 The box cover 92 has a main cover 921 and a side cover 922. Of course, some box covers 92 only have a main cover 921 but no side cover 922, and the box cover 92 uses the main cover 921 to cover the opening 914 of the box body 91. The accommodating space 913 of the box body 91 is isolated from the outside 93, so that the packaging box 90 can completely package the goods, and provide storage, storage and transportation of the goods.

The main cover 921 or/and the side cover 922 of the aforementioned box cover 92 are laminated with corrugated paper 924 and facial paper 927. The corrugated paper 924 has a corrugated paper 925 and a bottom paper 926. The corrugated paper 924 is on the inside and the facial paper 927 is on the outside. For printing, when the box cover 92 is damp, it will warp in the direction of the tissue 927 (as shown in Figure 10). Therefore, the box cover 92 and the box body 91 will be warped due to the warping of the box cover 92 A gap 93 is formed between the box body 91 (please refer to Figure 11), which affects the tightness and appearance of the packaging box 90, and the cut 95 caused by cutting on both sides of the main cover 921 and the side cover 922 is unsightly (see Figure 11). 9~10 pictures). In addition, if both sides of the main cover 921 and the side cover 922 of the box cover 92 are to be printed, the printing must be divided into two times, and continuous patterns cannot be printed.

The present invention provides a packaging box, which includes a box body with a bottom surface, and side surfaces are arranged around the bottom surface upwards. The bottom surface and the side surfaces form an accommodating space, and the top of the side surface has an opening , The accommodating space leads to the outside from the opening; a box cover, the box cover has a fixed end and a free end, the box cover can be movably connected to a side of the box body with the fixed end, so that the box The cover can move between covering the opening of the box body and opening the opening of the box body; it is characterized in that the box cover is laminated by a main cover layer and a sub-cover layer, and the main cover layer is composed of a main face paper and a main corrugated sheet. And a main bottom paper layered together, the auxiliary cover layer is formed by stacking a pair of face paper, a pair of corrugated and a pair of bottom paper, the auxiliary bottom paper of the auxiliary cover layer and the main bottom paper of the main cover layer Next to each other.

In the above-mentioned packaging box, wherein the main cover layer and the auxiliary cover layer of the box cover are bent and folded together in a continuous integrated structure, and a main reinforcing rib is formed at the bend.

In the above-mentioned packaging box, the auxiliary cover layer is folded and folded together by an integral structure extending from both sides of the main cover layer, and a main reinforcing rib is formed at each bending position on each side of the main cover layer.

The above-mentioned packaging box, wherein the secondary cover layer of the box cover is composed of the main cover layer The integral structure extending on the front side is folded and folded together, and a front reinforcing rib is formed at the bending part of the front side.

In the above-mentioned packaging box, a side cover is movably extended from the front side of the free end of the box cover, and the side cover is formed by stacking a main side cover and a secondary side cover, and the main side cover is composed of a main face paper, A main corrugated sheet and a main bottom paper are laminated, and the auxiliary side cover is laminated by a pair of face paper, a pair of corrugated sheets and a pair of bottom paper. The auxiliary bottom paper of the auxiliary side cover and the main side cover The main backing sheets are adjacent to each other.

In the above-mentioned packaging box, wherein the main side cover and the secondary side cover of the side cover are bent and folded together in a continuous integrated structure, and a pair of reinforcing ribs are formed at the bend.

In the above-mentioned packaging box, the secondary side cover of the side cover is folded and folded together by an integral structure extending from both sides of the main side cover, and a pair of reinforcing ribs are formed at each bend on each side.
