Technical Field
[0001] The utility model relates to the technical field of packaging boxes, in particular to a roll-up express packaging box. Background Art
[0002] Unlike 0210-type cartons, the entire process of making cartons is completed in the carton factory, and the contents are filled into the box after arriving at the user's factory. Instead, the die-cut carton blanks are only handed over to the packaging user, who uses an automatic packaging machine to put the contents and then roll it into a box. The characteristics of roll-type cartons are that less material is used, and the carton and the contents are tightly attached. For example, roll-type cartons are often used to package rolled mattresses.
[0003] The roll-packed mattress is mainly packed by vacuum compressing the mattress into a roll and putting it into a roll-type carton, thus solving the problem that the traditional flat-packed mattress occupies a large area and is not easy to operate in a small space during packaging and transportation. Existing roll-packed mattress cartons are usually packed in roll-type boxes, and the long sides of the roll-type boxes are connected by sealing nails. However, for heavy mattresses, it is often necessary to fix the long sides with tape or the like, which makes disassembly and assembly extremely troublesome.
[0004] In view of the above situation, designers need to design a roll-up carton that is easy to connect at both ends and has a stable and reliable connection position, so as to solve the problem that existing roll-up cartons need to be fixed with auxiliary tape when packaging heavy mattresses, which makes it inconvenient to disassemble and assemble. Utility Model Content
[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the utility model is to provide a roll-up express packaging box, by respectively arranging an insertion tongue piece and an outer edge connecting part at the tail of the long side of the roll-up box, and the two ends of the insertion tongue piece and the outer edge connecting part are respectively connected to the head and tail of the long side of the roll-up box to form a double-layer connecting layer together, so as to solve the problem that the existing roll-up carton needs to be fixed with auxiliary tape when packaging heavy mattresses, which makes it inconvenient to disassemble and assemble.
[0006] The technical solution of the utility model is as follows:
[0007] A roll-up express packaging box, comprising four pieces of paperboards connected in sequence on the sides, each piece of paperboard having sealing plates at both ends, each piece of paperboard comprising a plate-shaped inner layer, an outer layer and an interlayer, the inner layer, the outer layer and the interlayer being bonded to each other;
[0008] The tails of the four cardboards are provided with an insert tongue piece and an outer edge connecting part, which are respectively connected to the inner layer and the outer layer of the cardboard. When the four cardboards are connected head to tail, the insert tongue piece at the tail of the cardboard is inserted between the inner layer and the outer layer of the head of the cardboard, and the outer edge connecting part of the tail of the cardboard is located outside the outer layer of the head of the cardboard. The head of the cardboard is respectively connected to the insert tongue piece and the outer edge connecting part through sealing nails.
[0009] Furthermore, the four cardboards are cut and formed as a whole, and creases are pressed between each other; the inside of the cardboard between every two creases is compounded with an interlayer, so that the cardboard as a whole has higher strength and is safer during transportation.
[0010] Furthermore, the interlayer is integrally formed of high-density polyethylene plastic, and the interlayer of plastic material and the corrugated cardboard on both sides of the interlayer together form the four-sided wrapping of the packaging box. During the transportation of the packaging box, the interlayer sandwiched between the corrugated cardboard can support the weight of the middle part of the packaging box, thereby preventing the middle part of the packaging box from being bent due to force when the two ends of the packaging box are lifted.
[0011] Furthermore, the projection trajectory of the top view of the interlayer is a hyperbola intersecting in the middle.
[0012] Furthermore, the outer layers of the four cardboards are covered with a waterproof film to prevent the cardboards from getting damp and affecting the supporting strength.
[0013] The advantages of the utility model are:
[0014] 1. The utility model provides an inserting tongue piece and an outer edge connecting part at the tail of the long side of the roll-up box, and the two ends of the inserting tongue piece and the outer edge connecting part are respectively connected to the head and the tail of the long side of the roll-up box to form a double-layer connecting layer. The sealing nails pass through the outer edge connecting part, the outer layer of the paperboard, the inserting tongue piece and the inner layer of the paperboard to assemble the roll-up box. When the roll-up box is used to pack a heavy mattress, it does not need to be fixed with an auxiliary tape or the like, so that the box body has a higher connection strength.
[0015] 2. The utility model provides two interlayers with hyperbolic bending shapes between the inner layer and the outer layer, so that a gap can be left between the inner layer and the outer layer of the roll-up box, and the goods inside the roll-up box can be buffered during transportation. In addition, when the interlayers with hyperbolic distribution are subjected to upward force at both ends, they can fully support the middle bending part, thereby increasing the supporting strength of the roll-up box.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] The technical solution of the utility model is as follows:
[0021] A roll-type express packaging box, such as Figure 1-2 As shown, it comprises four paperboards whose sides are connected in sequence, each paperboard is provided with sealing plates 6 at both ends, each paperboard comprises a plate-shaped inner layer 1, an outer layer 3 and an interlayer 2, and the inner layer 1, the outer layer 3 and the interlayer 2 are adhered to each other;
[0022] The tail 5 of the four cardboards is provided with an insert tongue piece 5-1 and an outer edge connecting part 5-2, which are respectively connected to the inner layer 1 and the outer layer 3 of the cardboard. When the four cardboards are connected head to tail, the insert tongue piece 5-1 of the cardboard tail 5 is inserted between the inner layer 1 and the outer layer 3 of the cardboard head 4, and the outer edge connecting part 5-2 of the cardboard tail 5 is located outside the outer layer 3 of the cardboard head 4. The cardboard head 4 is respectively connected to the insert tongue piece 5-1 and the outer edge connecting part 5-2 by sealing nails.
[0023] The utility model provides an interlayer 2 in the middle of each cardboard, so that when a worker lifts the two ends of the roll-wrapped box to move, the interlayer 2 can enhance the supporting strength of the cardboard, and can avoid the middle part from collapsing when the two ends of the roll-wrapped box are subjected to force. In addition, an inserting tongue piece 5-1 is provided at the tail 5 of the four cardboards, and when the roll-wrapped box is assembled and installed, the inserting tongue piece 5-1 is inserted into the gap between the inner layer 1 and the outer layer 3 of the head 4 of the four cardboards, and then the outer edge connecting part 5-2 is placed on the outer side of the head 4 of the four cardboards, and the roll-wrapped box is assembled by passing the outer edge connecting part 5-2, the outer layer 3 of the cardboard, the inserting tongue piece 5-1 and the inner layer 1 of the cardboard with a sealing nail, so that the packaging of the roll-wrapped box can be more tightly connected, and the sealing edge of the roll-wrapped box in the length direction can be avoided from cracking during transportation.
[0024] Furthermore, the four paperboards are cut and formed as a whole, and creases are pressed between each other; the inside of the paperboard between every two creases is compounded with an interlayer 2, so that the paperboard as a whole has higher strength and is safer during transportation.
[0025] Furthermore, the interlayer 2 is integrally formed of high-density polyethylene plastic, and the interlayer 2 of the plastic material and the corrugated cardboard on both sides of the interlayer 2 together form the four-sided wrapping of the packaging box. During the transportation of the packaging box, the interlayer 2 sandwiched between the corrugated cardboard can support the weight of the middle part of the packaging box, thereby preventing the middle part of the packaging box from being bent due to force when the two ends of the packaging box are lifted.
[0026] Furthermore, the projection trajectory of the top view of the interlayer 2 is a hyperbola that intersects in the middle. The two interlayers 2 with hyperbolic bending shapes are compounded between the inner layer 1 and the outer layer 3, so that a gap can be left between the inner layer 1 and the outer layer 3 of the roll-wrapped box, which can buffer the goods inside the roll-wrapped box during transportation. In addition, when the interlayer 2 with a hyperbolic distribution is subjected to upward force at both ends, it can fully support the middle bend, which can increase the supporting strength of the roll-wrapped box.
[0027] Furthermore, the outer layers 3 of the four paperboards are all covered with a waterproof film to prevent the paperboards from getting damp and affecting the supporting strength.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
