Packaging carton

Abstract

The invention provides a packaging carton and discloses a packaging carton which uses a bottom inverted trapezoid hollow area for buffering and ventilation. The packaging carton is characterized in that an inner bottom plate is arranged on an outer bottom plate, the outer bottom plate is bent from the middle, and one side of the outer bottom plate is higher than the other side; two side edges of the inner bottom plate are bent downwards to be connected with two side edges of the outer bottom plate, the hollow area is arranged between the inner bottom plate and the outer bottom plate, the innerbottom plate and the outer bottom plate are combined to form a bottom plate, one side of the bottom plate is bent inwards, the hollow area is of an inverted trapezoid structure, an adhesive layer isarranged on the other side of the bottom plate, and the two bottom plates are horizontally placed; the two bottom plates adhere to each other through the adhesive layer, side face paper boards are distributed around the peripheries of the two bottom plates, and the side face paper boards are bent three times to form four parts; the included angle between every two adjacent parts is 90 degrees, andthe side panel paper boards are of a closed structure.

Description

technical field [0001] The invention relates to a packing carton, relates to a packing carton for packing transportation products, and belongs to the field of logistics transportation. In particular, it relates to a packaging carton which adopts an inverted trapezoidal hollow area at the bottom for cushioning and ventilation. Background technique [0002] At present, in the logistics transportation and product packaging, corrugated cartons are used for packaging, and the products are fully wrapped in cartons to protect the products and facilitate transportation and stacking. However, during transportation, the bottom of the cartons may become damp, mildewed, or damaged Especially during the transportation with a large north-south span, the climate environment causes the carton to deteriorate, which affects the use of the carton and the protection of the product.

Problems solved by technology

[0002] At present, in the logistics transportation and product packaging, corrugated cartons are used for packaging, and the products are fully wrapped in cartons to protect the products and facilitate transportation and stacking. However, during transportation, the bottom of the cartons may become damp, mildewed, or damaged Especially during the transportation with a large north-south span, the climate environment causes the carton to deteriorate, which affects the use of the carton and the protection of the product. In the existing logistics transportation, in order to prevent the carton from getting damp, a desiccant is placed in the box to absorb moisture. Gas, but it cannot be replaced and added according to the situation during transportation, and when stacking, the bottom surface of the box and the top surface of the next box are in close contact, and only the carton body is used for cushioning, so the cushioning capacity is poor. Extrusion stacking, lack of ventilation area in the middle, affects the odor diffusion of corrugated boxes

[0003] Publication number CN206734818U discloses a double-layer composite moisture-proof carton, which is characterized in that: it includes a carton body, and a layer of moisture-proof carton with the same structure as the carton body and different sizes is arranged outside the carton body, and the inner bottom surface of the moisture-proof carton is convex upwards. There is a push rod, the upper end of the push rod is horizontally provided with a support plate, the lower surface of the carton body is set on the support plate, and the four corners of the moisture-proof carton are provided with herringbone buckles. The herringbone buckle is set correspondingly to the four corners of the outer surface of the carton body. The device is packaged through a double-layer box to form a hollow area, which increases the occupied volume of the box and the number of boxes, and increases the cost. Its moisture-proof is only carried out through the hollow area. During transportation, the hollow area is easily deformed by external force, dumped and unstable.
