Description

Technical Field

[0001] The utility model belongs to the technical field of packaging boxes, and in particular relates to a novel high-weight slotted handmade small box. Background Art

[0002] At present, handmade cigarette boxes are mainly open boxes, that is, side openings, folded upwards to open the structure, this type of cigarette box has a strong sense of quality and grade. Its processing and cigarette loading can be completed by fully automatic equipment, which is convenient for processing and packaging, and has become the preferred packaging method for high-end cigarettes.

[0003] Traditional handmade boxes are composed of four parts: the face sheet, the upper cover, the lower cover and the surrounding strips. The face sheet is made of low-weight paper (generally 130-225 grams); the upper and lower covers are made of high-weight paper and glued to the face sheet with glue, and then the surrounding strips are implanted into the lower cover and glued to the side wall of the lower cover. One is to improve the strength of the box, and the other is to realize the opening function of the box.

[0004] Therefore, the hand-opened box involves many accessories in the pasting and molding process, and the processing procedures are complicated, resulting in a high cost for the hand-opened box.

[0005] Direct printing on heavy-weight cardboard can reduce the manual pasting process and reduce costs. However, the use of creasing technology on heavy-weight cardboard may cause interlayer structure bursting or high stiffness, making it difficult to fold and unable to be pasted on the machine, which cannot meet the requirements of fully automated equipment production. This has become the main problem to be solved by the utility model. Utility Model Content

[0006] The utility model aims to provide a novel high-weight slotted handmade small box to solve the above-mentioned technical problems.

[0007] In order to achieve the above purpose, the specific technical scheme of a new type of high-weight slotted handmade small box of the utility model is as follows:

[0008] A novel high-weight slotted handmade small box comprises a face sheet and a surrounding strip. The interlayer structure of the face sheet comprises a printing layer, a varnish layer, a PET film, an information layer, an aluminum-plated layer, and a paper base layer from top to bottom. The paper base layer is 300-400 grams of cardboard. The back of the paper base layer has a slot at the fold position. The paper base layer is divided into a bottom surface, an upper cover, and a side surface by the slot. The surrounding strip is enclosed to form a square frame of the same size as the bottom surface. The surrounding strip is vertically adhered to the slot around the bottom surface.

[0009] Furthermore, the groove is an inverted trapezoid or an inverted triangle.

[0010] Furthermore, the groove width is 0.6-0.8 mm, the depth is 0.3 mm-0.4 mm, and the opening angle is 120±10.

[0011] Furthermore, the side surfaces are divided into a bottom left side surface, a bottom right side surface, a bottom front side surface, a bottom rear side surface, an upper left side surface, an upper right side surface, an upper front side surface and an upper rear side surface, and the bottom left side surface, the bottom right side surface, the bottom front side surface and the bottom rear side surface are provided with an adhesive layer on the outer sides, and after folding, the upper left side surface is adhered to the bottom left side surface, the upper right side surface is adhered to the bottom right side surface, and the upper front side surface is adhered to the bottom front side surface, and a square box body is formed after adhesion.

[0012] Furthermore, after being pasted to form a square box body, the front side surface is cut along the groove between the bottom front side surface and the upper front side surface, and the left and right sides after pasting are cut along the center line to form an opening that can be opened along the front side surface.

[0013] Furthermore, the bottom left side, bottom right side and bottom front side are square, and the upper left side and upper right side have die-cut notches at the folding position, and the shape of the die-cut notches makes the sides of the upper cover complement each other after folding without overlap.

[0014] Furthermore, the strip is made of 400g white cardboard.

[0015] Furthermore, the surrounding strip has a fold, and the fold is an indentation.

[0016] Furthermore, the left side surface or the right side surface formed by the surrounding strips has a groove portion.

[0017] Furthermore, the front side surface formed by the surrounding strips is a curved surface, and the middle height of the curved surface is higher than the heights of the two sides.

[0018] The utility model discloses a new type of high-weight slotted handmade small box with the following advantages: the utility model adopts high-weight dough sheets for direct molding, eliminating the need to stick the upper cover and lower cover on the dough sheets with low weight to increase hardness, reduce consumables, and save costs. The folds of the dough sheets adopt the slotting process, the molding is square, the corners are stiff, and the horizontal folding is a right angle, with a strong hand feel; the bottom of the surrounding strip is directly glued to the slot, and there is no need to stick it on the side, avoiding the traditional large-area glue use and reducing the amount of glue used. It is not only green and environmentally friendly, but also achieves the purpose of reducing costs and increasing efficiency. Since the box body is formed by the dough sheet in an integrated manner, the dough sheet is printed on both sides, overcoming the traditional split printing and effectively avoiding color difference. And after the integrated molding opening, the upper and lower edge cut surfaces are the cross-sections of the whole paper cut, and the cut surfaces are smooth and neat.

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a new type of high-weight slotted handmade small box of the utility model in conjunction with the accompanying drawings.

[0028] like Figure 1 Figure 2 As shown, the utility model is a novel high-weight slotted handmade small box, comprising a surface sheet 1 and a surrounding strip 2, such as Figure 3 As shown, the interlayer structure of the face sheet 1 includes, from top to bottom, a printing layer 11, a varnish layer 12, a PET film 13, an information layer 14, an aluminum-plated layer 15, and a paper base layer 16. The paper base layer 16 is made of high-weight paper, preferably 300-400 grams of cardboard. Compared with the low-weight paper in the prior art, the high-weight upper and lower covers can be omitted, the pasting process can be saved, and the molding can be directly performed. The surrounding strip 2 is made of 400 grams of white cardboard.

[0029] Since the paper base 16 is made of high-weight paper, if the crease of the surface sheet is processed by the creasing process, there will be problems such as interlayer structure bursting or high stiffness, difficulty in folding, and inability to paste the box on the machine. Therefore, the utility model performs a slotting process at the position where the crease is required. After printing the graphic information, the outer edge of the surface sheet 1 is first die-cut, and then the back of the surface sheet 1 is respectively slotted horizontally and longitudinally. Figure 4As shown, the slot 161 is an inverted trapezoid or an inverted triangle. If the slot is too deep, it is easy to break, and if the slot is too shallow, the stiffness is too large and it is difficult to fold. Preferably, the slot 161 has a width of 0.6-0.8mm, a depth of 0.3mm-0.4mm, and an opening angle of 120±10 degrees. Figure 5 The figure shows the schematic diagram after folding, which is square and has firm corners. The slotting process is adopted to fold the paper horizontally into a right angle, which has a strong hand feel. At the same time, in order to solve the problem of ink bursting after folding, a PET film 13 is added between the varnish layer 12 and the information layer 14. The PET film 13 is a polyester substrate that can prevent the ink from bursting when folding.

[0030] like Figure 6 As shown, the paper base layer 16 is divided into a bottom surface 162, an upper cover 163 and a side surface 164 by a slot 161, and the side surface 164 is divided into a bottom left side 1621, a bottom right side 1622, a bottom front side 1623, a bottom rear side 1624, an upper left side 1631, an upper right side 1632, an upper front side 1633 and an upper rear side 1634. The surrounding strip 2 is formed into a square with the same size as the bottom surface 162, and the surrounding strip 2 has a fold, which is an indentation and is formed by pressing using an indentation process. Figure 7 As shown, the surrounding strip 2 is enclosed along the fold to form a square frame of the same size as the bottom surface 162, and the surrounding strip 2 is vertically adhered to the groove 161 around the bottom surface 162. The surface of the surrounding strip 2 does not need to be adhered to the side 164, avoiding the traditional large-area glue and reducing the amount of glue used. It is not only green and environmentally friendly but also achieves cost reduction and efficiency improvement. Preferably, the left side or right side formed by the surrounding strip 2 has a groove portion 21, and the groove portion 21 is convenient for taking out cigarettes. The front side formed by the surrounding strip 2 is a curved surface 22, and the middle height of the curved surface 22 is higher than the height of the two sides. It is convenient to open and close, and at the same time, the two sides do not collide with the edges when closed.

[0031] The bottom left side 1621, the bottom right side 1622, and the bottom front side 1623 are square, and the upper left side 1631 and the upper right side 1632 have a die-cut notch 1635 at the folding point. The shape of the die-cut notch 1635 makes the sides of the upper cover complement each other after folding without overlapping, preventing the increase of local thickness after folding, which affects the box shape and the final opening cutting.

[0032] The left side 1621, the right side 1622, the front side 1623 and the rear side 1624 of the bottom have a glue layer on the outside. After folding, the upper left side 1631 is glued to the left side 1621 of the bottom, the upper right side 1632 is glued to the right side 1622 of the bottom, and the upper front side 1633 is glued to the front side 1623 of the bottom. After gluing, a square box body is formed. Finally, the front side is cut along the slot 161 between the front side 1623 of the bottom and the upper front side 1633, and the left and right sides after gluing are cut along the center line to form an opening that can be opened along the front side. The box body is opened and closed. When the box body is turned over, the cut surface is neat. After opening, the upper and lower edges, the cut surface is the cross section of the whole paper cut, so it is smooth and neat.

[0033] When pasting the box, install a mold with the same shape as the interior of the box body into the bottom surface 162, then enclose the surrounding strip 2 from the side of the mold along the fold and stick it to the groove 161 on the bottom surface, and finally stick the side surface into shape. After the lamp glue dries, cut the front side surface and the left and right side surfaces along the center line to form an opening that can be opened along the front side surface, open the box body, and take out the mold.
