Description
Technical Field
The utility model relates to the technical field of cartons, in particular to a paper-saving compression-resistant carton.
Background
With the development of society, especially in recent years, the demand of cartons is gradually increased due to the rise of express delivery industry, the industrial production of replacing plastics with paper and replacing wood with paper, and the phenomenon of cutting trees is surprised because the solid waste paper cannot be imported and the raw materials for producing paper mainly depend on domestic trees. Under the strict requirements of the national environmental protection policy, saving paper, reducing carbon emission to reach carbon neutralization is the direction of enterprise innovation and production.
In 1856, the inventor of the British people Edward Hili and Edward Allen brothers invented the wider double corrugated cardboard in 1920 years in the corrugated cardboard structure, and until the world war period of the second time, the corrugated cardboard box had occupied 80% of goods transportation, and the annual output and sales of corrugated cardboard were up to trillion level. As paper prices have increased year after year, it is the current direction of research how to achieve cartons with greater compression resistance using a small amount of paper. Four-layer corrugated boards produced and used in the market have two types: one is to press two layers of corrugated paper into a composite corrugated structure by applying glue which is not regular (the corrugated paper is overlapped or staggered), and form four layers of paper boards with an upper layer paper and a lower layer paper, and the paper boards have the following defects: firstly, the corrugations are not pressed according to the rule, and the pressure resistance is poor; secondly, the corrugated paper has wide gluing surface, large glue consumption and high cost, and is not beneficial to environmental protection; and secondly, gluing and pressing the corrugated paper peak to form four layers of paper boards with the upper layer paper and the lower layer paper, wherein the gluing and pressing of the paper board peaks and the peaks reduces glue consumption and reduces cost, but the peaks are bonded to form rhombus, so that the paper boards are easy to stretch and expand and have poor pressure resistance.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art and provides the paper-saving compression-resistant carton which consumes less materials and has strong tensile compression resistance.
The utility model is realized by the following technical scheme: the paper-saving compression-resistant carton is formed by folding a paperboard, and is characterized in that the paperboard comprises a pressure bearing area in the middle and a non-pressure bearing area which is respectively connected with the upper end part and the lower end part of the pressure bearing area in a foldable manner, the pressure bearing area and the non-pressure bearing area respectively comprise upper-layer paper, upper corrugated paper, lower corrugated paper and bottom-layer paper which are sequentially bonded together, and interlayer paper is arranged between the upper corrugated paper and the lower corrugated paper of the pressure bearing area.
Furthermore, the upper corrugated paper and the lower corrugated paper in the non-pressure bearing area are connected with each other through ridges and peaks, and the ridges and the peaks between the lower corrugated paper of the upper corrugated paper box in the pressure bearing area are aligned and connected through interlayer paper.
The utility model has the beneficial effects that:
the utility model adopts the relative connection of the ridges and the ridges to increase the pressure resistance of the paperboard. Secondly, the paperboard is divided into a pressure bearing area and a non-pressure bearing area, and the upper corrugated paper and the lower corrugated paper are separated into a stable triangular structure by arranging the interlayer paper in the pressure bearing area, so that the compression resistance of the paperboard in the pressure bearing area is greatly improved, and meanwhile, the tensile resistance and the compression resistance of the whole carton are also improved; adopt stupefied peak and stupefied peak lug connection to reduce the consumptive material, reduce cost to the non-pressure-bearing area to guarantee that the whole tensile, compressive capacity of reinforcing of carton can also reduce consumptive material volume, reduce cost. Under the condition of meeting the national energy-saving and environment-friendly requirements, the production is stable and the economic benefit is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are further described below with reference to the following embodiments.
As shown in fig. 1 to 3, a paper-saving compression-resistant carton is formed by folding a paperboard 1, wherein the paperboard 1 comprises a pressure-bearing area 3 in the middle and a non-pressure-bearing area 32 respectively connected with the upper and lower end parts of the pressure-bearing area 3 in a foldable manner, the pressure-bearing area 3 and the non-pressure-bearing area 32 respectively comprise an upper layer of paper 101, an upper corrugated paper 102, a lower corrugated paper 104 and a bottom layer of paper 105 which are sequentially bonded together, and a sandwich paper 103 is arranged between the upper corrugated paper 102 and the lower corrugated paper 104 of the pressure-bearing area 3. The upper corrugated paper 102 and the lower corrugated paper 104 of the non-pressure bearing area 32 are connected with each other through ridges 106 and ridges 106, the ridges 106 between the upper corrugated paper 102 of the pressure bearing area 3 and the lower corrugated paper 104 are aligned with each other and connected through the laminated paper 103, the ranges of the pressure bearing area 3 and the non-pressure bearing area 4 can be reasonably adjusted according to different articles loaded on the carton, the front end part of the pressure bearing area 3 is provided with a sealing tongue 4, and the thickness of the laminated paper 103 is 0.5-1 mm.
As shown in fig. 4, when the corrugation pitch of the upper corrugated sheet and the corrugation pitch of the lower corrugated sheet are in a multiple relationship, the corrugation peaks and the corrugation peaks are in a non-one-to-one corresponding alignment relationship.
Firstly, processing and bonding an upper layer of paper 101 and an upper corrugated paper 102 by a corrugating machine, then coating glue on a crest 106 of the upper corrugated paper 102 by a glue spreader, processing and bonding a bottom layer of paper 105 and a lower corrugated paper 104 by the corrugating machine, then coating glue on the crest 106 of the lower corrugated paper 104 by the glue spreader, placing a sandwich paper 103 in the middle between the upper and lower corrugated papers 104 for bonding, and finally pressing and bonding by a pressing machine to form the paper-saving pressure-resistant paper board. The bearing area 3 and the non-bearing area 32 of the paper-saving compression-resistant paperboard are folded according to requirements, and the sealing tongue 4 is bonded at the rear end of the paperboard 1, so that the paper-saving compression-resistant carton is finally formed.
