Preferably, the two ends of the front bottom strip are respectively pressed below the side bottom strips at the two sides and are embedded between the bottom sheet and the side bottom strips.

Preferably, a first positioning crease is arranged between the front bottom strip and the front wall plate.

Preferably, a second positioning crease is arranged between the side bottom strip and the side wall plate. First location crease and second location crease are all strengthened, make positive bottom strip and side bottom strip paste the film, and make and turn over upward and roll over positive bottom strip or side bottom strip occasionally and restore to the horizontally elasticity to there is the fixed function of better location.

Preferably, the length of the first positioning crease is a, the length of the second positioning crease is b, the width of the front bottom strip is c, the width of the side bottom strip is d, a is less than b, and c is more than or equal to d. The two ends of the longer side bottom strip are used for pressing the front bottom strip of the shorter side, so that the fixation is more stable. When the height of the paper box is reduced, the paper box can be used as a paper cover.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the utility model is formed by cutting the integrated continuous paper boards, can complete assembly and buckling without any adhesive bonding, avoids the traditional paper boxes from being connected with the cover plate by surface and inner layer gluing, and has lower manufacturing cost, simpler and more convenient working procedure and more environmental protection in use; and each edge has high strength, is not easy to dent and deform, protects the paper box from stress deformation under certain pressure, has higher strength and strong pressure resistance, and is suitable for packaging products with higher requirements on the pressure resistance. When the height of the paper box is reduced, the paper box can be used as a paper cover, high strength is also kept, and the paper box is matched with the paper box to ensure that the overall strength is higher.
