All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to solve the problems that the structure of the packing box in the prior art is complex and the economy of the packing box is not facilitated, the utility model provides a packing protective lining and a packing box.

As shown in fig. 1 to 8, the package protective lining includes a plate body 10 and a limiting film 20, the plate body 10 includes a bottom plate 11 and a plurality of side plates 12, the plurality of side plates 12 are all connected with an edge of the bottom plate 11, and each side plate 12 is arranged in a foldable manner relative to the bottom plate 11; the limiting film 20 is placed on the first surface of the bottom plate 11, two ends of the limiting film 20 are respectively connected with the end parts of two side plates 12 which are oppositely arranged in the plurality of side plates 12, and an accommodating area is formed between the limiting film 20 and the first surface; the side plate 12 connected with the limiting film 20 can be folded towards the direction departing from the first surface to tighten the limiting film 20 so as to press and limit the object 1 to be packaged in the containing area; wherein, the curb plate 12 of being connected with spacing film 20 has a plurality of creases 100 of predetermineeing, and a plurality of creases 100 of predetermineeing set up along the direction looks interval that keeps away from bottom plate 11, along different creases 100 of predetermineeing and turn over the back and form the accommodation area that has not equidimension to adaptation in the not unidimensional packing article 1 of treating.

Through setting the packing protective lining to the structural style including plate body 10 and spacing film 20, and place spacing film 20 on the first surface of the bottom plate 11 of plate body 10, thereby make and form the accommodation region between spacing film 20 and the first surface, turn over the curb plate 12 of being connected with spacing film 20 through presetting crease 100 along the difference to the direction of keeping away from the first surface, thereby tighten spacing film 20, and then will treat that packing 1 compresses tightly spacingly in the accommodation region, ensure that packing protective lining treats packing 1's packing reliability.

In addition, because the curb plate 12 of being connected with spacing film 20 has a plurality of creases 100 of predetermineeing, and a plurality of creases 100 of predetermineeing set up along the direction looks interval of keeping away from bottom plate 11, ensure to turn over a curb plate 12 along the different creases 100 of predetermineeing and can form the not accommodation area of equidimension to adaptation in the not unidimensional packing article 1 of treating, promoted the application scope of packing protective lining greatly, and foretell packing protective lining's simple structure, convenient operation is swift.

As shown in fig. 4 to 8, the side plate 12, which is not connected to the stopper film 20, is folded toward the accommodation area. Thus, when the protective packaging lining is placed in the packaging box, the side plate 12 which is not connected with the limiting film 20 can be ensured to be abutted against the side wall surface of the packaging box.

Specifically, the side plate 12 not connected with the limiting film 20 is turned upwards by 90 degrees towards the accommodating area, so that the outer surface of the side plate 12 not connected with the limiting film 20 can be attached to the side wall surface of the packaging box as much as possible, and the limiting effect on the packaging protective lining is achieved.

Optionally, when the two oppositely arranged side plates 12 are folded upwards, the two oppositely arranged side plates are folded along the corresponding preset creases 100 on the two side plates 12 respectively; when the two oppositely arranged side plates 12 are folded downwards, the folding plates 121 are sequentially folded along the corresponding preset creases 100 on the two side plates 12.

As shown in fig. 6 to 8, each side panel 12 includes a plurality of flap panels 121, the flap panels 121 are connected in sequence, a predetermined fold 100 is formed between two adjacent flap panels 121, and after the flap panels 121 are folded in place, at least one flap panel 121 is perpendicular to the first surface. Therefore, when the packaging protective lining is placed into the packaging box, the turnover plate 121 perpendicular to the first surface can be attached to the side wall surface of the packaging box as much as possible, and therefore the limiting effect on the packaging protective lining is achieved.

In the present application, in order to ensure that the bottom plate 11 can maintain the horizontal plane after each side plate 12 is folded, as shown in fig. 1 to 8, the number of folded plates 121 on two side plates 12 provided to face each other among the plurality of side plates 12 is the same; the folding plates 121 on two oppositely disposed side plates 12 of the plurality of side plates 12 are disposed in a one-to-one correspondence, and the widths of the folding plates 121 corresponding to each other in the two side plates 12 are equal. Thus, the bottom plate 11 can be kept at a horizontal level all the time, so that the packaging object 1 is reliably supported, and the phenomenon that the packaging object 1 slides down due to the inclination of the bottom plate 11 in the process of transporting the packaging box is avoided.

Optionally, the width of each flap 121 on the same side panel 12 is equal, and the height of the flap 121 perpendicular to the first surface is equal when the flap 121 is folded into position. Thus, after each folding plate 121 is folded, the height of the folding plate 121 perpendicular to the first surface is kept unchanged, and the packaging box is suitable for packaging boxes with different accommodating spaces at the same height.

Optionally, the widths of the folding plates 121 on the same side plate 12 are not equal, and after the folding plates 121 are folded in place, the heights of the folding plates 121 perpendicular to the first surface are not equal. In this way, after each folding plate 121 is folded, the heights of the folding plates 121 perpendicular to the first surface are different, that is, the heights of the protective linings of the package can be adjusted by folding each folding plate 121, so that the packaging box is suitable for packaging boxes with different heights and different accommodating spaces.
