Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used based on the orientations and positional relationships shown in the drawings only for convenience of description and simplification of operation, and do not indicate or imply that the referred device or element must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 1, the present embodiment provides a packaging paper box 100, the packaging paper box 100 is used for a pot, and the packaging paper box 100 is formed by folding a paper material, so that the packaging paper box 100 is more environment-friendly and has no peculiar smell. Before the packaging paper box 100 is used, flat transportation can be carried out, and transportation and storage cost are saved.

Particularly, as shown in fig. 1, the packaging paper box 100 includes an outer box 1 and a buffering inner clamp 2, the buffering inner clamp 2 is arranged in the outer box 1, the buffering inner clamp 2 is used for buffering and fixing a pot, and the outer box 1 has a supporting and protecting effect on the buffering inner clamp 2 and the pot, so that the protection of the whole packaging paper box 100 on the pot is improved. It should be noted that, the size of the folding paper material can be correspondingly changed by the buffering inner clamp 2 according to the size of the actual cookware object, so that cookware products with different sizes can share the same outer box 1 after being fixed by the buffering of the buffering inner clamp 2, thereby satisfying the packaging requirements of cookware products with different sizes and improving the universality of the outer box 1.

In this embodiment, the paper materials used for the inner buffer card 2 and the outer box 1 are corrugated paper, and the corrugated paper has the advantages of light weight, high strength, no deformation, good rigidity and strong buffering performance.

Preferably, as shown in fig. 2, the outer box 1 is folded and formed in an airplane box structure. The structure is firm after aircraft box structure folding forming, also is convenient for folding forming to be convenient for production and processing. Since the aircraft box structure belongs to the prior art of the prior folding box forming, the description is omitted here.

As shown in fig. 1, the pot includes a pot main body 200, a pot cover 300 and a pot handle 400, the pot handle 400 is disposed on the pot main body 200, and the pot cover 300 is fastened on the pot main body 200. In order to facilitate fixing of the pot main body 200 and the pot lid 300 during transportation, the pot lid 300 is usually reversely fastened to the pot main body 200.

When the cookware is fixed in a buffering manner by the internal clamp of the existing packaging paper box 100, the cookware body 200 is fixed together with the cookware body 200 by the internal clamp after the cookware body 300 is reversely buckled on the cookware body 200, so that the cookware is easily shaken and collided in the transportation process between the cookware body 200 and the cookware body 300, and the cookware is damaged. In addition, because pan handle 400 is longer, the inside card only fills in pan main part 200 and pot lid 300 position department in outer box 1 inside for there is the surplus space in pan handle 400 position inside outer box 1, makes outer box 1 take place sunken easily under the effect of external force extrusion, reduces the structural strength of packing carton 100.

In order to solve the above problem, as shown in fig. 3, the buffer inner clip 2 includes a first buffer portion 21, a filling support portion 22 and a second buffer portion 23 connected in sequence, the first buffer portion 21 and the second buffer portion 23 are matched with each other to separate, buffer and fix the pot main body 200 and the pot lid 300, and the filling support portion 22 is filled in the cavity of the outer box 1 and buffers and fixes the pot handle 400. This setting mode can avoid pan main part 200 and pot lid 300 to bump in the transportation, improves the buffer protection to pan main part 200 and pot lid 300. Fill supporting part 22 and fill in the cavity of outer container 1 and cushion fixed pan handle 400, not only can effectively cushion fixed pan handle 400, still make the inside of outer container 1 whole filled, cushion the protection pan better, improved the structural strength of whole packing carton 100.
