High-strength and recyclable tobacco strip honeycomb box

Abstract

The invention discloses a high-strength and recyclable tobacco strip honeycomb box. The high-strength and recyclable tobacco strip honeycomb box comprises an inner box and an outer box, the inner boxand the outer box are correspondingly composed of side walls and swing covers, the side walls are spliced by two side plates which are bent at 90 degrees, folding structures between the side plates and the swing covers are composed of at least two inward turning indentations located on the folding inner sides of the inner box / outer box and at least one outward turning indentation located on the folding outer sides of the inner box / outer box, and the inward turning indentations and the outward turning indentations are distributed in a staggered mode; and bending parts of the side walls are composed of at least one inward bending indentation located on the bending inner sides of the inner box / outer box and at least two outward bending indentations located on the bending outer sides of the inner box / outer box, and the inward bending indentations and the outward bending indentations are distributed in a staggered mode. According to the high-strength and recyclable tobacco strip honeycomb box, the compressive strength reaches up to 11.3 KPa, compared with a tobacco strip box with the same thickness or weight processed by corrugated paper, the compressive strength of the high-strength and recyclable tobacco strip honeycomb box is as high as 3 times of the corrugated tobacco strip box, and the high-strength and recyclable tobacco strip honeycomb box can be recycled for more than 10 times.

Description

technical field [0001] The invention relates to a tobacco storage device, in particular to a high-strength recyclable tobacco honeycomb box. Background technique [0002] Lamina FCL is a packaging box for laminar tobacco. The existing 200kg re-roasted carton of laminar tobacco is generally composed of an inner box and an outer box. It has the advantages of environmental protection, easy folding, and convenient transportation. It has been It basically replaces wooden plywood packaging boxes, mainly including corrugated box and honeycomb box. [0003] The inner box and the outer box of the corrugated box in the prior art are all made of seven-layer corrugated cardboard to ensure that it meets the anti-corrugated box specified in the tobacco industry standard YC / T137. The compressive strength is not less than 2.65×10 4 N requirements, but the production of seven-layer corrugated cardboard requires a large amount of base paper, resulting in heavy weight and high cost of the ca...

Problems solved by technology

[0005] Because the stable hexagonal structure of the honeycomb core has an excellent ability to bear axial loads, the honeycomb paperboard has the outstanding characteristics of high rigidity, high flat compressive strength, and strong bending resistance. At the same time, the bending strength of the honeycomb core has Due to the characteristics of heterogeneity and inhomogeneity, the creases are usually formed along the edge of the honeycomb core instead of a straight line when it is bent; the indentation of the honeycomb paperboard in the prior art is easily damaged due to the loss of strength during use

[0006] Although the inner box and the outer box of the existing honeycomb carton utilize its honeycomb structure, the compressive strength of the carton has been improved, such as the laminar inner box disclosed in CN107323864A, the laminar whole box and the laminar whole box processing method, because its side wall The folded structure formed by flat pressing with the bottom folded leaf is likely to lose strength due to the connection structure between the bottom folded leaf and the side wall due to the slitting and pressing line slots, which in turn leads to the failure of containing cigarettes. The honeycomb carton cannot meet the requirements for the carrying capacity of the cigarette box during the storage of the cigarettes; and the above-mentioned whole box of the cigarettes is easily damaged due to structural damage during recycling, which meets the requirements for the compressive strength of the cigarette box, resulting in the inability to be recycled again
