Abstract
The invention relates to a heavy-duty paper box having variable bearing capacity. According to the heavy-duty paper box, the inner walls of a group of side plates having a large area are respectively adhered with a group of core paper plates, wherein the core paper plates are folded and cross sections of the core paper plates have a trapezoidal wavy shape; the inner sides of the core paper plates are adhered with a layer of a tearing line paper plate, such that the side wall of the paper box is changed into a composite paper plate formed by three layers of paper plates so as to increase compressive strength and bending strength; and if the compressive strength of the paper box does not meet the requirement, the inner side of the composite paper plate can be added with a layer of the composite paper plate formed by the three layers of the paper plates, and pressing combination is performed, such that the two layers of the composite paper plates are integratedly inserted so as to effectively improve a strength of the paper box and so as not to occupy a volume of the paper box.
Description
Technical field
The present invention relates to a kind of packaging structure, the variable heavy type carton of especially a kind of bearing capacity.
Background technology
At present, the carton of various shapes and sub-assembly thereof are widely used in daily life and industrial production, but in the packing of some heavy article, it is inadequate that corrugated case easily shows compression strength, occurring rise drum etc. of carton sidewall in the pile process exists in the phenomenon, particularly carton in the situation in larger spaces even more serious; Honeycomb cardboard cooperates the heavy type carton cost that consists of too high with corrugated board corner protector, and moulding process is too complicated.For improving the compression strength of carton, people have proposed various settling modes.Be CN201120196527.8 at application number, name is called: disclose a kind of carton in the patent document of high-intensity carton, comprise the casing that is formed by the corrugated paper bending, this casing side of being body, it is characterized in that, described bottom half inboard is provided with four reinforcements, and described reinforcement lays respectively at four bights of bottom half inboard.The major defect that this high-intensity carton exists is: at the inboard reinforcement that increases of bottom half, be difficult to guarantee the overall construction intensity of carton, and the larger easy bulging phenomenon that rises of sidewall of area.At application number be: CN201020532749.8, name is called: open reinforced carton in the patent document of carton, casing is square, and the junction of two lateral surfaces of square box arbitrary neighborhood all arranges the square corner protector; Described casing and square corner protector are by upper strata brown paper, honeycomb paper core and the bonding formation of lower floor's brown paper, upper strata brown paper is bonded on the end face of honeycomb paper core, lower floor's brown paper is bonded on the bottom surface of honeycomb paper core, and the honeycomb hole cross section in the honeycomb paper core is regular hexagon.The major defect that this packaged form exists is: processing technology is complicated, can not guarantee the efficient of suitability for industrialized production.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can Effective Raise carton compression intensity also can plug together the method that again improves carton compression intensity through secondary as required.
According to technical scheme provided by the invention, the heavy type carton structure that described bearing capacity is variable, that each bonding one group of its folding cross section of process is trapezoidal wavy core paper plate on one group of larger side plate inwall of heavy type carton area, inboard bonding one deck at the core paper plate has the tear line cardboard again, make the sidewall of carton become the combination board that is consisted of by triplex board, improve its compression strength and flexural strength.If the compression strength of carton does not still reach requirement, can add again the combination board that one deck is made of triplex board in the combination board inboard, and by pressing, two-layer combination board be plugged together be integrated, both effectively improved the intensity of carton, do not take again the volume of carton.
The invention has the advantages that: (1) has improved the compression strength of carton effectively, has reduced the rise generation of bulging phenomenon of carton sidewall; (2) triple wall board is bonded as a kind of combination board again, under the condition of controlling cost, improves carton intensity; (3) two-layer combination board can plug together and be integrated, and has realized to a certain extent the controllability of carton intensity.

Specific embodiments
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the heavy type carton structure 1 that this bearing capacity is variable, it is each bonding one group of core paper plate 3 through folding on one group of larger side plate 2 inwall of carton area, the cardboard 4 that many tear lines 5 are arranged at inboard bonding one deck of core paper plate again, make the sidewall of carton become the combination board that is consisted of by triplex board, improve its compression strength and flexural strength.If the compression strength of carton does not still reach requirement, can add again in the combination board inboard combination board 6 that one deck is made of triplex board, and by pressing, two-layer combination board be plugged together be integrated, both effectively improve the intensity of carton, do not changed again the volume of carton.
The used combination board of described load-bearing carton, the cross section of its core paper plate 3 is trapezoidal wavy texture, and outer adhesive surface unit 10 is wider than interior adhesive surface unit 8, and its stand out is the thickness of core paper plate.
In the described core paper plate 3, the gap width between two adhesive units 8 equals the length on isosceles trapezoid inclined-plane 9.
On the described carton of inner layer 4, the center between two adhesive unit faces 8 has a tear line 5, two combination boards to plug together in the process, and tear line 5 disconnects, and carton of inner layer 4 is fractured into the strip cardboard, and is coated on the trapezoidal inclined plane 9.
After described combination board plugged together and finishes, inner plating 4 and 7 the plane of disruption and trapezoidal inclined plane 9 formed buckle structures, prevent that interior combination board from coming off.
Described combination board is composited by single wall corrugated board, and its stupefied shape can be according to the packing Location of requirement of specific product.
