Description

Technical Field

[0001] The utility model belongs to the technical field of boxes or packages for storing or transporting objects or materials in IPC classification B65D5 / 54, and relates to a structural innovation and improvement technology of a printing and die-cutting plate that can be folded into a packaging box, especially this printing and die-cutting plate structure is suitable for convenient printing, die-cutting, magnetizing, pasting and folding to produce corresponding small-sized magnetic packaging box products. Background Art

[0002] In the production process of printed packaging boxes, semi-finished die-cut sheets before folding and forming are usually called "die-cut semi-finished products" or "die-cut parts". After the die-cutting process, these semi-finished products have the basic shape and structure of the packaging box, but have not yet been folded and formed. These die-cut semi-finished products will be folded, pasted and other processes in the subsequent production process to finally form a complete packaging box. Therefore, they play a vital role in the entire production process and are a key link in ensuring the quality and appearance of the packaging box.

[0003] The structure of a printed magnetic packaging box usually includes a paper box body, a magnetic flap, a magnetic component, and decorative elements. The paper box body is the basic structure of the packaging box, which is used to contain and protect the product. The magnetic flap is connected to the paper box body through the magnetic component, and can fit tightly through magnetic adsorption when closed, increasing the closure and convenience of the packaging box.

[0004] The magnetic components generally include magnetic sheets or magnets set at corresponding positions on the paper box body and the magnetic flap. These magnetic components attract each other through magnetic force to achieve automatic adsorption and closure of the flap. Decorative elements include translucent plastic decorative panels and film stickers, etc., which are used to improve the aesthetics of the packaging box and the product display effect.

[0005] In terms of production methods, the production of printed magnetic packaging boxes mainly includes the following steps:

[0006] The first is design: the structural design and appearance design of the packaging box are carried out according to customer needs and product characteristics, and the size, shape, color and pattern are determined.

[0007] The second is printing: using spot color printing or four-color printing, etc., to print the required patterns and texts on the packaging box materials. The printing process requires preparing the printing plate, designing the printing process, mixing the ink, and performing steps such as gluing, printing and drying.

[0008] The third is processing: after printing, the packaging box is processed by die-cutting, folding, embossing, glazing and laminating to increase its practicality and decorative effect. The die-cutting process is used to cut the packaging box into the required shape, and the folding process makes the packaging box foldable for easy storage and transportation.

[0009] Fourth, assembly: assemble the processed parts, including installing magnetic components and decorative elements. The magnetic components need to be accurately installed in the predetermined position to ensure the effective effect of the magnetic force.

[0010] The fifth is quality inspection and packaging: the assembled packaging boxes are inspected to ensure that their quality meets the standard requirements. After passing the quality inspection, they are packaged and shipped.

[0011] The existing magnetic packaging box is a paper product used to package products. The molding of the existing common packaging boxes is mostly through gluing and the clamping formed by the packaging and its own structure. Due to the small size of small-sized magnetic packaging boxes, some accessories cannot be pasted on the gift box machine and can only be pasted manually, which will cause the pasting position to be inaccurate. It is inconvenient to position and paste, which restricts the production quality and makes it difficult for product demand to get production support. The main reason is that there is a lack of die-cutting structure design for corresponding small-sized magnetic packaging boxes suitable for production and use. Utility Model Content

[0012] The technical problem to be solved by the utility model is to make up for the lack of a small-sized magnetic packaging box and a structural design of a die-cut piece thereof which is convenient for positioning and pasting.

[0013] In view of the above problems and technical requirements, the utility model proposes a small-sized magnetic packaging box and die-cut parts thereof that are easy to position and paste, which can ensure convenient production and product quality.

The side of the box lid facade adjacent to the box lid side surface is connected to the cover facade side tongue outward. Furthermore, the side tongue of the cover facade adjacent to the cover facade folded edge extends outward to form a side tongue pressure angle, and a folding line is pressed on the connection edge of the cover facade folded edge and the side tongue pressure angle.

[0016] The magnetic attraction structure in the top edge of the box body, i.e., the setting position of the magnetic piece on the box body edge, corresponds to the magnetic attraction structure in the lower edge of the box cover, i.e., the setting position of the magnetic piece on the box cover edge.

[0017] After the adjusting piece is fitted with the movable edge of the top opening of the box body on the top surface edge of the enclosed box body, the separation structure formed by the alignment of the cutouts on the top edge of the box body on both sides is formed.

[0018] The magnetic attraction structure in the top edge of the box body, i.e., the setting position of the magnetic piece on the box body edge, corresponds to the magnetic attraction structure in the lower edge of the box cover, i.e., the setting position of the magnetic piece on the box cover edge.

[0043] For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by the specific situation. When there is a conflict, the definition in this specification shall prevail. It should be noted that:

[0044] If the word “a” or “an” appears in the present invention, it should be read as including one or at least one, and the singular form of elements or components also includes the plural form unless the number is obviously intended to be in the singular form.

[0045] In the description of the present utility model, the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0046] In the description of the present utility model, it is also necessary to explain that, unless otherwise clearly stipulated and limited, the terms "set", "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements.

[0047] The principle of the utility model is that usually the front of the printing plate will print graphic content, and then it will be directly die-cut. In the previous and subsequent processes, there will be errors in the edge of the front graphic, as well as errors in the back gluing and folding position, and further lead to the finished product size and shape structure not being accurate enough to the standard. This will exceed the limited fault tolerance of small-sized packaging boxes for processing errors. In particular, in order to accurately mount the small-sized packaging boxes, it has been found through research and experiments that the convenience and accuracy of processing can be improved by optimizing the design of the printing plate die slices and their shapes and structures. At the same time, the knife plate line is made or printed on the back of the printing plate, so that manual mounting can be performed according to the position of the knife plate line, thereby improving the accuracy of the mounting position. Specifically, a crimping knife or a crimping die is used to press a line mark on the back of the sheet by pressure, or a line roller is used to roll a line mark on the sheet, so that the sheet can be bent and formed according to the predetermined position. The printed cardboard or paperboard is die-cut to fix its outer contour into a box base, which is folded in sequence according to the molded line marks. The die-cut folded edges, folded tongues, presser feet and other tongue-shaped flap structures are inserted into corresponding positions in coordination with each other, and a standard bonding strength of the overlapping area is formed in the process of forming into a box.

[0048] In the utility model, the size of the die-cut piece needs to be very precise to ensure its fit with the packaging box. Slight deviations may lead to large errors in positioning and pasting. Based on the optimization of the shape of the die-cut piece and taking into account the characteristics of the small-sized packaging box, the shape of the die-cut piece should be as simple as possible to avoid overly complex graphics, which can reduce errors and difficulties in the production process. Obvious line marks are set on the back of the printing plate as positioning marks for die-cutting and pasting and folding so that the position of the die-cut piece can be found quickly and accurately during the pasting process. These preset line marks include grooves, protrusions or other printed marks, and the magnetic part of the magnetic packaging box must ensure that the magnetic attraction is strong enough, and avoid magnetic interference during the pasting process. The positioning accuracy of die-cutting, folding, pasting and assembly is affected.

[0049] The utility model comprises: a box body die-cutting piece 1, a box cover die-cutting piece 2, a lining die-cutting piece 3, a magnetic attraction structure 4 and a glue coating area 5.

The outer bottom piece 110 is connected to the lower side of the first vertical surface 101 of the box body, and the inner bottom piece 111 is connected to the lower side of the second vertical surface 102 of the box body; the second side surface 104 of the box body, the first vertical surface 101 of the box body, the first side surface 103 of the box body, the second vertical surface 102 of the box body and the stacked side surface 105 are of the same height, the second side surface 104 of the box body, the first side surface 103 of the box body and the stacked side surface 105 are of the same width, the first vertical surface 101 of the box body and the second vertical surface 102 of the box body are of the same width, and the width of the first vertical surface 101 of the box body is greater than that of the first side surface 103 of the box body; the outer bottom piece 110 is rectangular, and the inner bottom piece 111 is trapezoidal. When the box body die-cut part 1 is rolled, the folded tongue 109 on the side of the box bottom is aligned with or even overlapped with the inner sheet 111 of the box bottom, and then overlapped and covered on the outside to bond the outer sheet 110 of the box bottom; at the same time, after the long side 107 of the box body top is rolled, the tail end is pressed against the live edge 108 of the box body top, and the second side surface 104 of the box body is overlapped and bonded with the overlapped side surface 105.

[0053] In the foregoing, refer to the attached Figure 3 and 4 As shown, on the die-cut part 2 of the box cover, the outer edge of the box cover vertical surface 202 opposite to the box cover top surface 201 is connected to the cover vertical surface folding edge 2021, and a folding line is pressed on the root of the cover vertical surface folding edge 2021, that is, on the connection edge with the box cover vertical surface 202; the outer edge of the box cover side surface 203 opposite to the box cover top surface 201 is connected to the cover side folding tongue 2031, and a folding line is pressed on the root of the cover side folding tongue 2031, that is, on the connection edge with the box cover vertical surface 202; and a glue coating area 5 is provided on both sides of the folding line. The side of the box cover vertical surface 202 adjacent to the box cover side surface 203 is connected to the outside of the cover vertical surface 202. Further, the side tongue pressing angle 2023 of the cover vertical surface side tongue 2022 protrudes outward from the side adjacent to the cover vertical surface folding edge 2021, and a folding line is pressed on the connection edge of the cover vertical surface folding edge 221 and the side tongue pressing angle 2023. When the die-cut part 2 of the box lid is folded and enclosed, firstly, the cover vertical folded edge 2021, the cover vertical side tongue 2022, the side tongue pressure angle 2023 and the cover side folded tongue 2031 are respectively folded inwardly and pasted with the outer glue coating area 5, and a group of box lid edge magnetic sheets 402 are added; then, the box lid is further enclosed along the box lid vertical surface 202 and the box lid side surface 203, and the box lid side surface 203 and the cover vertical side tongue 2022 are respectively overlapped and bonded alternately.

[0054] In the above, on the edge of the top surface of the box body after being enclosed, after the adjusting piece 303 is fitted with the movable edge 108 of the top opening of the box body, the separation structure formed by the alignment of the cutout 106 of the top edge of the box body with the adjusting cutout 304 on both sides makes the adjusting piece 303 and the movable edge 108 of the top opening of the box body have a certain degree of freedom. When the box cover is pressed on the top opening of the box body, the adjusting piece 303 and the movable edge 108 of the top opening of the box body are moved inward as necessary to ensure that the pressed edge of the box cover is completely and smoothly buckled on the top opening of the box body and locked. At the same time, the box cover edge magnetic piece 402 set in the box cover edge is attracted to the box body edge magnetic piece 401 set in the box body edge.

[0055] In the above, the magnetic attraction structure 4 in the top edge of the box body, i.e., the magnetic piece 401 at the edge of the box body, corresponds to the magnetic attraction structure 4 in the lower edge of the box cover, i.e., the magnetic piece 402 at the edge of the box cover.

[0056] In the above, the lining die-cut piece 3 is based on the adjustment sheet 303 being pressed and glued to the inner side of the live edge 108 of the box body top opening of the box body die-cut piece 1, and the lining sheet 301 is sequentially pasted to the second side surface 104 of the box body, the first vertical surface 101 of the box body, the first side surface 103 of the box body and the second vertical surface 102 of the box body. At the same time, the adjustment cutout 304 is aligned with the cutout 106 of the box body top edge, and the pasting live edge 302 is pasted to the long side 107 of the box body top opening.

[0057] In the above, a group of box body edge magnetic sheets 401 are arranged in the adhesive interlayer between the second side surface 104 of the box body, the first vertical surface 101 of the box body, the first side surface 103 of the box body or the second vertical surface 102 of the box body and the lining die-cut piece 3, that is, in the middle of the lower side of the long side 107 of the top opening of the box body.

[0058] In the above, a group of glue coating areas 5 are evenly arranged in the bonding interlayer between the second side surface 104 of the box body, the first vertical surface 101 of the box body, the first side surface 103 of the box body or the second vertical surface 102 of the box body and the lining die-cut piece 3, that is, on the lower side of the long side 107 of the top opening of the box body; the group of glue coating areas 5 are distributed in the dot matrix glue coating points at the edge and the middle; or, the whole width is glued.

[0059] In the above, in the length expansion direction of the box body die-cut piece 1, that is, along the second side surface 104 of the box body, the first vertical surface 101 of the box body, the first side surface 103 of the box body to the second vertical surface 102 of the box body, the length of the box cover die-cut piece 2 is slightly shorter than the total length of the second side surface 104 of the box body, the first vertical surface 101 of the box body, the first side surface 103 of the box body to the second vertical surface 102 of the box body, and the length difference is 2-5 times the thickness of the box body die-cut piece 1.

[0060] In the above description, the long side 107 of the top opening of the box body and the lining live edge 302 are similar in shape, and the area difference is compensated by more than 2%.

[0061] In the above, the height of the box cover die-cut piece 2 after rolling is slightly greater than 1 / 2 of the height of the box body die-cut piece 1 after rolling.

[0062] In the above, the side folding tongue 109 of the bottom of the box is an equilateral trapezoidal structure, the side tongue 2022 of the cover vertical surface is a right-angled trapezoidal structure; and the side tongue pressure angle 2023 is a right-angled triangle.

[0063] Preferably, the materials of the box body die-cut piece 1, the box cover die-cut piece 2, and the lining die-cut piece 3 should have sufficient rigidity and toughness so as to maintain a stable shape during the positioning and pasting process.

[0064] Preferably, the magnetic structure 4 includes a magnetic sheet 401 on the edge of the box body and a magnetic sheet 402 on the edge of the box lid, which are usually strong neodymium iron boron magnets, which are widely used in the packaging industry. These magnetic sheets are commonly found in various packaging boxes, such as wine boxes, gift boxes, tea boxes, etc., and are used to provide convenient closing and opening methods. The shape and size of the magnetic sheet will vary depending on the specific packaging box design and requirements. Common shapes include round, square, etc., and the sizes are also different. When selecting a magnetic sheet, factors such as the size and weight of the packaging box and the required suction force need to be considered. The performance of the magnetic sheet is an important consideration. Although the performance requirements of the packaging magnet are not high, it is also necessary to select an appropriate brand to meet the suction requirements. At the same time, in order to reduce costs, galvanized magnetic sheets can also be selected because the galvanizing cost is low and the working environment requirements of the magnet are not strict.

[0065] Preferably, the adhesive selected from the glue coating area 5 includes:

[0066] PVA glue: It is a strong adhesive, usually used on the inside of packaging boxes. It is more environmentally friendly and can filter through the pores of paper during the stitching or gluing process to form a strong bonding point. In addition, it can also make the surface smooth.

[0067] Hot Melt Glue: It is a liquid glue with very strong adhesion and needs to be melted when used. It is usually applied to the corrugated paper of the packaging box. It has good adhesion and can firmly bond the corrugated paperboard. It can form beautiful lines and uniform glue when applied.

[0068] EVA glue: This is a common glue that is nearly transparent. It is suitable for situations where there are high requirements for the appearance of the packaging box, and can achieve the effect of not affecting the beauty of the packaging. EVA glue has a wide range of applications and can be used for bonding a variety of materials such as paper, plastic, and cloth.

[0069] Latex glue: This glue has a higher viscosity, is easy to clean and lasts longer. It can better bond thicker materials, but may not be as hard, so it is not suitable for long-term weight bearing.

[0070] In addition to the above-mentioned common glues, there are also some special-purpose glues, such as corrugated box glue, carton sealing glue, etc. These glues are usually selected and used according to the specific needs of the carton.

[0071] When choosing glue for packaging boxes, you need to consider multiple factors, including the type of glue, viscosity, drying speed, water resistance and weather resistance, etc. At the same time, you also need to choose according to the material and process requirements of the packaging box to ensure the bonding effect and the overall quality of the packaging box.

[0072] In the embodiment of the utility model, two sets of box body die-cut pieces 1, box cover die-cut pieces 2 and lining die-cut pieces 3 are spliced ​​on the printing plate.
