High-strength honeycomb strips box

Abstract

The invention relates to a high-strength honeycomb strips box. The high-strength honeycomb strips box comprises an inner box and an outer box, the inner box is composed of an inner side plate and an inner rocking cover, and the inner side plate and the inner rocking cover are integrally formed; the outer box is composed of an outer side plate and an outer rocking cover, and the outer side plate and the outer rocking cover are integrally formed; the folding structure between the inner side plate and the inner rocking cover and between the outer side plate and the outer rocking cover is composedof at least two inner indentations located on the folding inner side face of the inner box / outer box and at least one outer indentation located on the folding outer side face of the inner box / outer box, and the inner indentations and the outer indentations are distributed in a staggered mode. According to the high-strength honeycomb strips box, by improving the folding structure between the rocking cover and the side plates, deformation of the honeycomb paperboard during folding in the using process of the strips box is reduced, the compressive strength of the paperboard and the compressive strength of the whole strips box are improved, and compared with a strips box processed by corrugated paper with the same thickness or weight, the compressive strength is three times the compressive strength of a corrugated strips box.

Description

technical field [0001] The invention relates to a tobacco storage device, in particular to a high-strength honeycomb sheet smoke 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 carton, a...

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, due to 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. Honeycomb cartons cannot meet the requirements for the carrying capacity of cigarette boxes during the storage of tobacco
