Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to a cluster packaging box for canned products. Background Art

[0002] Canning is a packaging method that encapsulates products (such as food, beverages, chemicals, etc.) in containers such as metal cans and plastic cans. Its advantages include good sealing, convenient transportation and storage, and effective isolation from air, moisture, and light, while also resisting a certain degree of external compression and microbial contamination, thereby extending the product's shelf life. Currently, canned beverages (such as herbal tea, soda, coffee, juice, beer, etc.) are the most common and widely distributed on the market. Cardboard boxes or shrinkable film (also known as shrink film) are commonly used to package multiple cans of beverages. Cardboard boxes completely cover the cans, wasting packaging materials and making them inconvenient to carry and prevent the cans from being displayed. Shrink film also violates the original intention of using paper packaging to protect the environment and is not conducive to recycling.

[0003] In related technologies, multiple canned drinks can be arranged together and then packaged in cluster packaging boxes. Typically, cluster packaging boxes only cover the bottom, top, and two opposite sides of these canned drinks, which has the following advantages: the canned drinks can be fully displayed; the overall packaging is more beautiful and easier to attract consumers' attention; the single purchase volume of canned drinks can be increased, which helps promote canned drinks; it is ergonomic and easy to carry; and the material is paper, which is more environmentally friendly. However, in order to meet the portable needs of cluster packaging boxes, additional handles are often required on the cluster packaging boxes, which increases the production process of the cluster packaging boxes and reduces production efficiency. Moreover, when consumers use the handles to grab the cluster packaging boxes, the handles can easily break, which not only reduces the stability of the cluster packaging boxes in portable scenarios, but also seriously affects the consumer's shopping experience. Utility Model Content

[0004] The present application provides a cluster packaging box for canned products, aiming to solve the problems of low production efficiency and poor stability of cluster packaging boxes in related technologies in a portable manner.

[0005] In order to solve the above-mentioned drawbacks existing in the related art, the present application provides a cluster packaging box for canned products, which is used to package a canned product unit, and the canned product unit includes multiple canned products stacked or arranged together according to a predetermined rule. Specifically, the cluster packaging box includes panels, and the panels include a top panel, a left panel, a right panel, a lower bottom panel, and an upper bottom panel. The lower bottom panel, the left panel, the top panel, the right panel, and the upper bottom panel are connected in sequence, and a first fold is formed between any two connected panels. After a folding operation is performed based on each first fold, the lower bottom panel, the left panel, the top panel, the right panel, and the upper bottom panel enclose a receiving space, and the upper bottom panel is bonded to the lower bottom panel. The lower bottom panel is provided with a lower through hole, and the upper bottom panel is provided with an upper through hole aligned with the lower through hole. Among them, the receiving space is used to accommodate the canned product unit; the top panel, upper bottom panel, left panel and right panel are used to respectively abut the top, bottom and opposite sides of the canned product unit; the lower through hole and upper through hole are used for allowing users to observe the product information marked on the bottom of each canned product, and for the user's fingers to be inserted in sequence; the lower bottom panel and upper bottom panel are used to withstand the pulling force from the user after the user's fingers are inserted into the lower through hole and the upper through hole in sequence.

[0006] In some implementations, the lower bottom panel and the upper bottom panel have the same shape and size. After the upper bottom panel is bonded to the lower bottom panel, the edge of the upper bottom panel away from the right panel abuts the first fold between the lower bottom panel and the left panel.

[0007] In some implementations, there is at least one lower through-hole and at least one upper through-hole. If there are multiple lower through-holes and multiple upper through-holes, the multiple lower through-holes are spaced apart on the lower bottom panel, and the multiple upper through-holes are spaced apart on the upper bottom panel, and the multiple lower through-holes are aligned with the multiple upper through-holes. In one implementation, there are four lower through-holes and four upper through-holes, and the four lower through-holes are arranged in a 2×2 pattern on the lower bottom panel, while the four upper through-holes are arranged in a 2×2 pattern on the upper bottom panel.

[0008] In some implementations, the upper bottom panel has at least one glue coating area for coating glue, and the upper bottom panel is bonded to the lower bottom panel via the glue in the glue coating area.

[0009] In some implementations, the upper bottom panel is provided with at least one adhesive strip coated with glue, and the upper bottom panel is bonded to the lower bottom panel via the adhesive strip. In one implementation, the adhesive strip is provided with a plurality of adhesive holes spaced apart, each of which contains adhesive.

[0010] In some implementations, the lower bottom panel, left side panel, top panel, right side panel, and upper bottom panel are all rectangular, with the two opposite short sides of the left side panel connected to the lower bottom panel and the top panel, respectively, and the two opposite short sides of the right side panel connected to the top panel and the upper bottom panel, respectively. The two opposite long sides of the left side panel are each connected to a first protective panel, with opposite ends of the first protective panel connected to the lower bottom panel and the top panel, respectively. The two opposite long sides of the right side panel are each connected to a second protective panel, with opposite ends of the second protective panel connected to the top panel and the upper bottom panel, respectively. The first protective panel is configured to fold along the long side of the left side panel into the receiving space under the action of an external force when the canned product unit is placed in the receiving space. The second protective panel is configured to fold along the long side of the right side panel into the receiving space under the action of an external force when the canned product unit is placed in the receiving space.

[0011] In one implementation scheme, the outline of the first protective panel includes a first straight line segment extending from the corner point of the lower bottom panel to the left side panel, a second straight line segment extending from the corner point of the top panel to the left side panel, a first arc segment extending from the corner point of the lower bottom panel to the left side panel, a second arc segment extending from the corner point of the top panel to the left side panel, a third arc segment connecting the first arc segment and the second arc segment, and a third straight line segment connecting the first straight line segment and the second straight line segment, the third straight line segment coincides with the long side of the left side panel, the first straight line segment and the second straight line segment coincide with the edges of the lower bottom panel and the top panel respectively; a second fold is formed between the left side panel near the corner point of the lower bottom panel and the intersection of the first arc segment and the third arc segment, and the left side panel near the corner point of the top panel and the second arc segment coincide with the third straight line segment. A third fold is formed between the intersection points of the three arc segments, and the second fold and the third fold divide the first protective panel into a first corner protection area connected to the lower bottom panel, a second corner protection area connected to the top panel, and a first edge protection area connected between the first corner protection area and the second corner protection area; a fourth fold is formed at a corner of the lower bottom panel where it connects to each first corner protection area, and the fourth fold and the second fold intersect at the corner point of the left panel close to the lower bottom panel, and the fourth fold is used to divide the third corner protection area connected to the first corner protection area from the lower bottom panel; a fifth fold is formed at a corner of the top panel where it connects to each second corner protection area, and the fifth fold and the third fold intersect at the corner point of the left panel close to the top panel, and the fifth fold is used to divide the fourth corner protection area connected to the second corner protection area from the top panel.

[0012] Specifically, the first edge protection area is configured to fold along the long side of the left panel into the receiving space after the canned product unit is placed in the receiving space; the first corner protection area and the second corner protection area are configured to fold along the second crease and the third crease, respectively, while the first edge protection area is folded along the long side of the left panel into the receiving space; the third corner protection area and the fourth corner protection area are configured to fold along the fourth crease and the fifth crease, respectively, after the first corner protection area and the second corner protection area are folded along the second crease and the third crease, respectively, into the receiving space. Furthermore, the first edge protection area is hollowed out at the angle between the second crease and the long side of the left panel, and at the angle between the third crease and the long side of the left panel.

[0013] In one implementation scheme, the outline of the second protective panel includes a fourth straight line segment extending from the corner point of the upper bottom panel to the right side panel, a fifth straight line segment extending from the corner point of the top panel to the right side panel, a fourth arc segment extending from the corner point of the upper bottom panel to the right side panel, a fifth arc segment extending from the corner point of the top panel to the right side panel, a sixth arc segment connecting the fourth arc segment and the fifth arc segment, and a sixth straight line segment connecting the fourth straight line segment and the fifth straight line segment, the sixth straight line segment coincides with the long side of the right side panel, the fourth straight line segment and the fifth straight line segment coincide with the edges of the upper bottom panel and the top panel respectively; a sixth fold is formed between the right side panel near the corner point of the upper bottom panel and the intersection of the fourth arc segment and the sixth arc segment, and the right side panel near the corner point of the top panel and the fifth arc segment coincide with the sixth fold. A seventh fold is formed between the intersection points of the six arc segments, and the sixth and seventh folds divide the second protective panel into a fifth corner protection area connected to the upper bottom panel, a sixth corner protection area connected to the top panel, and a second edge protection area connected between the fifth corner protection area and the sixth corner protection area; an eighth fold is formed at a corner where the upper bottom panel is connected to each fifth corner protection area, and the eighth fold and the sixth fold intersect at the corner point of the right side panel close to the upper bottom panel, and the eighth fold is used to divide the seventh corner protection area connected to the fifth corner protection area from the upper bottom panel; a ninth fold is formed at a corner where the top panel is connected to each sixth corner protection area, and the ninth fold and the seventh fold intersect at the corner point of the right side panel close to the top panel, and the ninth fold is used to divide the eighth corner protection area connected to the sixth corner protection area from the top panel.

[0014] Specifically, the second edge protection area is configured to fold into the receiving space along the long side of the right panel after the canned product unit is placed in the receiving space. The fifth and sixth corner protection areas are configured to fold outward from the receiving space along the sixth and seventh folds, respectively, while the second edge protection area is folded into the receiving space along the long side of the right panel. The seventh and eighth corner protection areas are configured to fold into the receiving space along the eighth and ninth folds, respectively, after the fifth and sixth corner protection areas are folded outward from the receiving space along the sixth and seventh folds, respectively. Furthermore, the angles between the sixth fold and the long side of the right panel, and between the seventh fold and the long side of the right panel, on the second edge protection area are both hollowed out.

[0015] In some implementations, the two corners of the lower bottom panel that are not connected to the left panel and the two corners of the upper bottom panel that are not connected to the right panel are removed, and arc-shaped notches are opened on the two opposite edges of the lower bottom panel, top panel and upper bottom panel that are perpendicular to the first fold.

[0016] The bundle packaging box provided in the present application is composed of a top panel, a left panel, a right panel, a lower bottom panel and an upper bottom panel. The lower bottom panel, the left panel, the top panel, the right panel and the upper bottom panel are connected in sequence. A first crease is formed between any two connected panels. After folding operations based on each first crease, the lower bottom panel, the left panel, the top panel, the right panel and the upper bottom panel are combined to form a receiving space. The upper bottom panel is adhered to the lower bottom panel. A lower through hole is opened on the lower bottom panel, and an upper through hole aligned with the lower through hole is opened on the upper bottom panel. In actual application, the canned product unit can be placed in the receiving space, and the top panel, upper bottom panel, left panel and right panel can respectively abut the top, bottom and opposite sides of the canned product unit; the user (such as a consumer) can pass through the lower through hole and the upper through hole in turn to observe the product information marked on the bottom of each canned product (such as production date, shelf life, etc.); the user can also insert his fingers into the lower through hole and the upper through hole in turn to lift the cluster packaging box and the canned product unit inside it. At this time, the lifting force applied by the user will be borne jointly by the lower bottom panel and the upper bottom panel. It can be seen that when the canned product unit needs to be transported (that is, the cluster packaging box needs to be carried and moved), the user can insert his fingers into the lower through hole on the lower bottom panel and the upper through hole on the upper bottom panel in turn, and then the cluster packaging box can be lifted and moved. In the process of the user carrying the cluster packaging box, the lifting force applied by the user is always borne by the two layers of panels (that is, the lower bottom panel and the upper bottom panel). This double-panel force-bearing method is more stable and will not break as easily as the handle of the traditional solution, thereby reducing the risk of the cluster packaging box falling and improving the stability of the cluster packaging box in the hand-carrying scenario, thereby ensuring the consumer's shopping experience; in addition, the present application integrates the hand-carrying function of the cluster packaging box with the function of observing the canned product related information (both achieved through the lower through hole and the upper through hole), so there is no need to set an additional handle on the cluster packaging box, thereby reducing the production process of the cluster packaging box and improving the production efficiency of the cluster packaging box.

DETAILED DESCRIPTION

[0021] In the related art, multiple canned beverages can be arranged together first, and then packaged in a cluster packaging box. Compared with cartons and shrink films, cluster packaging boxes only cover the bottom, top, and opposite sides of these canned beverages. Although they have many advantages, in order to meet the portable requirements of cluster packaging boxes, it is often necessary to set additional handles on the cluster packaging boxes, which increases the production process of the cluster packaging boxes and reduces production efficiency. Moreover, when consumers grab the cluster packaging boxes by the handles, the handles are easy to break, causing the cluster packaging boxes to fall, which can damage the cluster packaging boxes at the least and break the canned beverages at the worst. This not only reduces the stability of the cluster packaging boxes in the portable scenario, but also seriously affects the consumer's shopping experience. In view of this, the present application proposes a cluster packaging box for canned products in the following embodiments to solve the above-mentioned drawbacks existing in the related art.

[0022] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] See also Figure 1 , Figure 1 This embodiment provides a cluster packaging box, which is used to package a canned product unit. The canned product unit includes a plurality of canned products stacked or arranged together according to a predetermined rule. It should be noted that the number of canned products included in the canned product unit and the stacking or arrangement form of these canned products are determined according to actual needs, and this application does not make the sole limitation on this. For example, the canned product unit can be: two canned products are placed upright (also called vertically, which means that the length direction of the canned products is perpendicular to the placement surface), and the two canned products are side by side; two canned products are placed upside down (also called horizontally, which means that the length direction of the canned products is parallel to the placement surface), and the two canned products are stacked together; four canned products are placed upright, the four canned products are in contact with each other and arranged in 2×2; four canned products are placed upside down, every two canned products are stacked together to form a group, and two groups of canned products are side by side; six canned products are placed upright, the six canned products are in contact with each other and arranged in 2×3; eight canned products are placed upright, the eight canned products are in contact with each other and arranged in 2×4; eight canned products are placed upright, every four canned products are in contact with each other and arranged in 2×2 to form a group, and two groups of canned products are stacked together. It should also be noted that the canned products of this embodiment can be any commonly used canned food or beverage in the art, such as canned meat, canned vegetables, canned fruit, canned herbal tea, canned soda, canned coffee, canned juice, canned beer, etc. The specific canned product can be selected based on actual needs and is not limited to this by this application. Preferably, the material used for the cluster packaging box is coated kraft paper with long fibers, high density, high toughness, and high tear strength.

[0024] Specifically, the bundle packaging box of this embodiment includes panels (not shown in the figure), and the panels include a top panel 3, a left side panel 2, a right side panel 4, a lower bottom panel 1 and an upper bottom panel 5. The lower bottom panel 1, the left side panel 2, the top panel 3, the right side panel 4 and the upper bottom panel 5 are connected in sequence, and a first crease e is formed between any two connected panels. After a folding operation based on each first crease e, the lower bottom panel 1, the left side panel 2, the top panel 3, the right side panel 4 and the upper bottom panel 5 are enclosed to form a receiving space (not shown in the figure), and the upper bottom panel 5 is adhered to the lower bottom panel 1, and a lower through hole 11 is opened on the lower bottom panel 1, and an upper through hole 51 is opened on the upper bottom panel 5, and the upper through hole 51 is aligned with the lower through hole 11. In this embodiment, the receiving space is used to accommodate the canned product unit; the top panel 3 is used to abut the top of the canned product unit; the upper bottom panel 5 is used to abut the bottom of the canned product unit; the left side panel 2 and the right side panel 4 are used to abut the opposite sides of the canned product unit respectively; the lower through hole 11 and the upper through hole 51 are used for allowing the user to observe the product information marked on the bottom of each canned product (such as production date, shelf life, etc.), and for the user (such as the consumer) to insert the fingers in turn; the lower bottom panel 1 and the upper bottom panel 5 are used to withstand the pulling force from the user after the user's fingers are inserted into the lower through hole 11 and the upper through hole 51 in turn.

[0025] That is to say, in actual application, the canned product unit can be placed in the receiving space, and the top panel 3, the upper bottom panel 5, the left panel 2 and the right panel 4 can respectively abut the top, bottom and opposite sides of the canned product unit; the user's line of sight can pass through the lower through hole 11 and the upper through hole 51 in turn to observe the product information marked on the bottom of each canned product; the user can also insert his fingers into the lower through hole 11 and the upper through hole 51 in turn to lift the cluster packaging box and the canned product unit inside it. At this time, the lifting force applied by the user will be borne jointly by the lower bottom panel 1 and the upper bottom panel 5. In addition, it should be noted that when the canned product unit is placed in the receiving space, the canned product unit is not completely covered by the cluster packaging box, but only the opposite sides are covered by the cluster packaging box. This allows the canned products in the canned product unit to still be fully displayed to consumers, making it easier for consumers to understand the products.

[0026] As can be seen from the above, if the canned product unit needs to be transported (i.e., the cluster packaging box needs to be carried by hand), the user can insert their fingers into the lower through hole 11 on the lower bottom panel 1 and the upper through hole 51 on the upper bottom panel 5 in sequence, and then lift the cluster packaging box to move it. In the process of the user carrying the cluster packaging box, the lifting force applied by the user is always borne by the two panels (i.e., the lower bottom panel 1 and the upper bottom panel 5). This double-panel force-bearing method is more stable and will not break easily like the handles of traditional solutions, thereby reducing the risk of the cluster packaging box falling and improving the stability of the cluster packaging box in the hand-carrying scenario, thereby ensuring the consumer's shopping experience. In addition, this embodiment integrates the hand-carrying function of the cluster packaging box with the function of viewing canned product-related information (both achieved through the lower through hole 11 and the upper through hole 51). In this way, there is no need to set an additional handle on the cluster packaging box, thereby reducing the production process of the cluster packaging box and improving the production efficiency of the cluster packaging box.

[0027] In some embodiments, see Figure 1 The shape and size of the lower bottom panel 1 and the upper bottom panel 5 are the same. After the upper bottom panel 5 is bonded to the lower bottom panel 1, the upper bottom panel 5 is away from the edge of the right side panel 4 (i.e. Figure 1 E) abuts against the first fold e between the lower bottom panel 1 and the left side panel 2. It is understandable that, when the lower bottom panel 1 and the upper bottom panel 5 are of the same shape and size, after the upper bottom panel 5 and the lower bottom panel 1 are bonded together, if the edge of the upper bottom panel 5 away from the right side panel 4 abuts against the first fold e between the lower bottom panel 1 and the left side panel 2, then it means that the upper bottom panel 5 and the lower bottom panel 1 are not offset and overlapped (i.e., only partially overlapped), but completely overlapped. This can improve the ability of the upper bottom panel 5 and the lower bottom panel 1 to withstand the lifting force applied by the user, thereby further improving the stability of the bundled packaging box in the hand-carrying scenario; of course, in other embodiments, when the upper bottom panel 5 and the lower bottom panel 1 are bonded together, the upper bottom panel 5 and the lower bottom panel 1 can also be offset and overlapped. The specific selection can be based on actual needs, and this application does not make a sole limitation to this. In addition, it should be noted that since the upper bottom panel 5 and the lower bottom panel 1 have the strongest ability to withstand the lifting force applied by the user when they are completely overlapped, after the upper bottom panel 5 and the lower bottom panel 1 are bonded together, the upper bottom panel 5 and the lower bottom panel 1 are preferably completely overlapped.

[0028] In some embodiments, still refer to Figure 1, the lower through hole 11 and the upper through hole 51 each include at least one, when the lower through hole 11 and the upper through hole 51 each include multiple, the multiple lower through holes 11 are distributed at intervals on the lower bottom panel 1, the multiple upper through holes 51 are distributed at intervals on the upper bottom panel 5, and the multiple lower through holes 11 are respectively aligned with the multiple upper through holes 51. It is understandable that when the user inserts his fingers into the lower through hole 11 and the upper through hole 51 in turn to grab the cluster packaging box, the more fingers inserted, the more stable the grabbing of the cluster packaging box. Moreover, when there are more canned products in the storage space, if there is only one lower through hole 11 and one upper through hole 51, it may be difficult to observe the product information marked on the bottom of each canned product. Therefore, it is preferred that there are multiple lower through holes 11 and multiple upper through holes 51. As for the number of lower through holes 11 and upper through holes 51, it can be determined according to actual needs, as long as "the number of lower through holes 11 and upper through holes 51 is the same" and "the multiple lower through holes 11 are respectively aligned with the multiple upper through holes 51" are met, this application does not make a sole limitation on this. Exemplarily, there are four lower through holes 11 and four upper through holes 51. The four lower through holes 11 (represented by a, b, c, and d respectively) are arranged in a 2×2 pattern on the lower bottom panel 1, and the four upper through holes 51 (represented by A, B, C, and D respectively) are arranged in a 2×2 pattern on the upper bottom panel 5. Then, after the upper bottom panel 5 and the lower bottom panel 1 are bonded together, the alignment relationship between the upper through holes 51 and the lower through holes 11 is: A is aligned with a; B is aligned with b; C is aligned with c; and D is aligned with d.

[0029] In some embodiments, see Figure 1The lower bottom panel 1, left side panel 2, top panel 3, right side panel 4, and upper bottom panel 5 are all rectangular. The two opposite short sides of the left side panel 2 are connected to the lower bottom panel 1 and the top panel 3, respectively. The two opposite short sides of the right side panel 4 are connected to the top panel 3 and the upper bottom panel 5, respectively. The two opposite long sides of the left side panel 2 are connected to a first protective panel 6, and the opposite ends of the first protective panel 6 are connected to the lower bottom panel 1 and the top panel 3, respectively. The two opposite long sides of the right side panel 4 are connected to a second protective panel 7, and the opposite ends of the second protective panel 7 are connected to the top panel 3 and the upper bottom panel 5, respectively. Specifically, the first protective panel 6 is configured to fold along the long side of the left side panel 2 into the receiving space under the action of an external force after the canned product unit is placed in the receiving space. The second protective panel 7 is configured to fold along the long side of the right side panel 4 into the receiving space under the action of an external force after the canned product unit is placed in the receiving space. That is to say, in actual application, after placing the canned product unit in the receiving space, the user can fold the first protective panel 6 and the second protective panel 7, so that the first protective panel 6 is folded into the receiving space along the long side of the left panel 2, and the second protective panel 7 is folded into the receiving space along the long side of the right panel 4. In this way, protection can be formed on the relative sides of the canned product unit that are not in contact with the left panel 2 and the right panel 4, which can effectively prevent the canned products in the receiving space from escaping from the receiving space, that is, reducing the risk of the canned products in the receiving space falling, and further improving the stability of the bundled packaging box in the portable scenario.

[0030] As one or more embodiments thereof, the outline of the first protective panel 6 includes a first straight line segment f extending from the corner point (i.e., the vertex) of the lower bottom panel 1 to the left side panel 2, a second straight line segment g extending from the corner point of the top panel 3 to the left side panel 2, a first arc segment i extending from the corner point of the lower bottom panel 1 to the left side panel 2, a second arc segment j extending from the corner point of the top panel 3 to the left side panel 2, a third arc segment k connecting the first arc segment i and the second arc segment j, and a third straight line segment h connecting the first straight line segment f and the second straight line segment g, the third straight line segment h coincides with the long side of the left side panel 2, and the first straight line segment f and the second straight line segment g coincide with the edges of the lower bottom panel 1 and the top panel 3, respectively.

[0031] Specifically, a second fold l is formed between the corner point of the left side panel 2 close to the lower bottom panel 1 and the intersection of the first arc segment i and the third arc segment k, and a third fold m is formed between the corner point of the left side panel 2 close to the top panel 3 and the intersection of the second arc segment j and the third arc segment k. The second fold l and the third fold m can divide the first protective panel 6 into three areas, namely, a first corner protection area 61 connected to the lower bottom panel 1, a second corner protection area 62 connected to the top panel 3, and a first edge protection area 63 connected between the first corner protection area 61 and the second corner protection area 62.

[0032] Furthermore, a fourth fold n is formed at a corner where the lower bottom panel 1 connects to each first corner protection area 61, and the fourth fold n and the second fold l intersect at the corner point of the left side panel 2 close to the lower bottom panel 1. The fourth fold n is used to divide the third corner protection area 12 connected to the first corner protection area 61 from the lower bottom panel 1; a fifth fold o is formed at a corner where the top panel 3 connects to each second corner protection area 62, and the fifth fold o and the third fold m intersect at the corner point of the left side panel 2 close to the top panel 3. The fifth fold o is used to divide the fourth corner protection area 31 connected to the second corner protection area 62 from the top panel 3.

[0033] In actual application, the first edge protection area 63 is used to fold the canned product unit along the long side of the left panel 2 into the receiving space under the action of external force after the canned product unit is placed in the receiving space; the first corner protection area 61 and the second corner protection area 62 are used to fold the first edge protection area 63 along the long side of the left panel 2 into the receiving space, and at the same time, fold the first corner protection area 63 along the long side of the left panel 2 into the receiving space, and at the same time, fold the first corner protection area 63 along the long side of the left panel 2 into the receiving space, and at the same time, fold the first corner protection area 12 and the fourth corner protection area 31 are used to fold the first corner protection area 61 and the second corner protection area 62 along the second fold 1 and the third fold m into the receiving space under the action of external force.

[0034] That is to say, after placing the canned product unit in the receiving space, the user can fold the first edge protection area 63 so that the first edge protection area 63 is folded into the receiving space along the long side of the left panel 2. At the same time, the first corner protection area 61 and the second corner protection area 62 will be folded out of the receiving space along the second fold l and the third fold m respectively. After the first edge protection area 63, the first corner protection area 61 and the second corner protection area 62 are all folded into place, the user can fold the third corner protection area 12 and the fourth corner protection area 31 so that the third corner protection area 12 and the fourth corner protection area 31 are folded into the receiving space along the fourth fold n and the fifth fold o respectively. In this way, protection can be formed on the opposite sides of the canned product unit where it is not in contact with the left panel 2 and the right panel 4. Preferably, in order to facilitate the folding of the first edge protection area 63 along the long side of the left panel 2 into the receiving space, the first edge protection area 63 is hollowed out at the angle between the second fold 1 and the long side of the left panel 2, and the first edge protection area 63 is hollowed out at the angle between the third fold m and the long side of the left panel 2.

[0035] As one or more embodiments thereof, the outline of the second protective panel 7 includes a fourth straight line segment p extending from the corner point of the upper bottom panel 5 to the right side panel 4, a fifth straight line segment q extending from the corner point of the top panel 3 to the right side panel 4, a fourth arc segment s extending from the corner point of the upper bottom panel 5 to the right side panel 4, a fifth arc segment t extending from the corner point of the top panel 3 to the right side panel 4, a sixth arc segment u connecting the fourth arc segment s and the fifth arc segment t, and a sixth straight line segment r connecting the fourth straight line segment p and the fifth straight line segment q, the sixth straight line segment r coincides with the long side of the right side panel 4, and the fourth straight line segment p and the fifth straight line segment q coincide with the edges of the upper bottom panel 5 and the top panel 3, respectively.

[0036] Specifically, a sixth fold v is formed between the corner point of the right side panel 4 close to the upper bottom panel 5 and the intersection of the fourth arc segment s and the sixth arc segment u, and a seventh fold w is formed between the corner point of the right side panel 4 close to the top panel 3 and the intersection of the fifth arc segment t and the sixth arc segment u. The sixth fold v and the seventh fold w can divide the second protective panel 7 into three areas, namely, the fifth corner protection area 71 connected to the upper bottom panel 5, the sixth corner protection area 72 connected to the top panel 3, and the second edge protection area 73 connected between the fifth corner protection area 71 and the sixth corner protection area 72.

[0037] Furthermore, an eighth fold x is formed at a corner where the upper bottom panel 5 connects to each fifth corner protection area 71, and the eighth fold x and the sixth fold v intersect at the corner point of the right side panel 4 close to the upper bottom panel 5. The eighth fold x is used to divide the seventh corner protection area 53 connected to the fifth corner protection area 71 from the upper bottom panel 5; a ninth fold y is formed at a corner where the top panel 3 connects to each sixth corner protection area 72, and the ninth fold y and the seventh fold w intersect at the corner point of the right side panel 4 close to the top panel 3. The ninth fold y is used to divide the eighth corner protection area 32 connected to the sixth corner protection area 72 from the top panel 3.

[0038] In actual application, the second edge protection area 73 is used to fold the canned product unit into the receiving space along the long side of the right side panel 4 under the action of external force after the canned product unit is placed in the receiving space; the fifth corner protection area 71 and the sixth corner protection area 72 are used to fold the second edge protection area 73 into the receiving space along the long side of the right side panel 4, and fold them out of the receiving space along the sixth fold v and the seventh fold w respectively; the seventh corner protection area 53 and the eighth corner protection area 32 are used to fold the fifth corner protection area 71 and the sixth corner protection area 72 into the receiving space along the sixth fold v and the seventh fold w respectively under the action of external force after the fifth corner protection area 71 and the sixth corner protection area 72 are folded out of the receiving space along the sixth fold v and the seventh fold w respectively.

[0039] That is to say, after placing the canned product unit in the receiving space, the user can fold the second edge protection area 73 so that the second edge protection area 73 is folded into the receiving space along the long side of the right side panel 4. At the same time, the fifth corner protection area 71 and the sixth corner protection area 72 will be folded out of the receiving space along the sixth fold v and the seventh fold w respectively. After the second edge protection area 73, the fifth corner protection area 71 and the sixth corner protection area 72 are all folded into place, the user can fold the seventh corner protection area 53 and the eighth corner protection area 32 so that the seventh corner protection area 53 and the eighth corner protection area 32 are folded into the receiving space along the eighth fold x and the ninth fold y respectively. In this way, protection can be formed on the opposite sides of the canned product unit that are not in contact with the left panel 2 and the right panel 4. Preferably, in order to facilitate the folding of the second edge protection area 73 along the long side of the right side panel 4 into the receiving space, the second edge protection area 73 is hollowed out at the angle between the sixth fold v and the long side of the right side panel 4, and the second edge protection area 73 is hollowed out at the angle between the seventh fold w and the long side of the right side panel 4.

[0040] In some embodiments, still refer to Figure 1 The upper bottom panel 5 is provided with at least one glue coating area 52, and the glue coating area 52 is used to apply glue, so that the upper bottom panel 5 is bonded to the lower bottom panel 1 through the glue in the glue coating area 52. It is understandable that when the lower bottom panel 1, the left side panel 2, the top panel 3, the right side panel 4, and the upper bottom panel 5 are enclosed to form a receiving space, the upper bottom panel 5 needs to be bonded to the lower bottom panel 1. Therefore, the present application provides at least one glue coating area 52 for applying glue on the upper bottom panel 5, and the glue in each glue coating area 52 can achieve bonding between the upper bottom panel 5 and the lower bottom panel 1. In addition, it should be noted that the enclosure of the receiving space and the bonding of the upper bottom panel 5 and the lower bottom panel 1 in the present application are completed before the cluster packaging box leaves the factory. That is to say, before the cluster packaging box leaves the factory, the enclosure of the receiving space and the bonding of the upper bottom panel 5 and the lower bottom panel 1 will be automatically performed by relevant equipment. In this case, when the cluster packaging box leaves the factory, the packaging personnel only need to fold the first protective panel 6, the second protective panel 7, etc., which means that the packaging process of the canned product unit does not include the enclosure of the receiving space and the bonding of the upper bottom panel 5 and the lower bottom panel 1. This can greatly simplify the packaging process of the canned product unit and improve the packaging efficiency of the canned product unit.

[0041] Of course, the bonding structure provided on the upper bottom panel 5 is not limited to the glue-coating area 52 for applying glue. In other embodiments, the glue-coating area 52 can be replaced by a glue strip (not shown), that is, at least one glue strip is provided on the upper bottom panel 5, and glue is coated on the surface of the glue strip, so that the upper bottom panel 5 can be bonded to the lower bottom panel 1 through the glue strip. Preferably, the glue strip is provided with a plurality of glue holes (not shown) distributed at intervals, and each glue hole contains glue. In other words, the glue is not only present on the surface of the glue strip, but also in the plurality of glue holes provided on the surface of the glue strip. In this way, when the upper bottom panel 5 and the lower bottom panel 1 are bonded, the glue in each glue hole will seep out, thereby enhancing the bonding effect between the upper bottom panel 5 and the lower bottom panel 1, ensuring the overall stability of the cluster packaging box, and further improving the stability of the cluster packaging box in a portable scenario.

[0042] In some embodiments, still refer to Figure 1 In order to take into account the material usage, production cost and stability of the cluster packaging box, the two corners of the lower bottom panel 1 that are not connected to the left panel 2 are removed, and the two corners of the upper bottom panel 5 that are not connected to the right panel 4 are removed. The lower bottom panel 1 is provided with an arc-shaped notch 8 on the two opposite edges perpendicular to the first fold e, the top panel 3 is provided with an arc-shaped notch 8 on the two opposite edges perpendicular to the first fold e, and the upper bottom panel 5 is provided with an arc-shaped notch 8 on the two opposite edges perpendicular to the first fold e, so as to optimize the material usage, production cost and stability of the cluster packaging box.

[0043] The above embodiments are only preferred implementations of the present application and are not the only limitations on the contents of the cluster packaging box. Those skilled in the art can flexibly set them based on the above embodiments according to the actual application scenarios. It can be understood that, through the implementation of the above embodiments of the present application, the top panel 3, the left panel 2, the right panel 4, the lower bottom panel 1 and the upper bottom panel 5 are used to form a cluster packaging box. The lower bottom panel 1, the left panel 2, the top panel 3, the right panel 4 and the upper bottom panel 5 are connected in sequence. A first fold e is formed between any two connected panels. After folding based on each first fold e, the lower bottom panel 1, the left panel 2, the top panel 3, the right panel 4 and the upper bottom panel 5 are enclosed to form a receiving space. The upper bottom panel 5 is bonded to the lower bottom panel 1. The lower bottom panel 1 is provided with a lower through hole 11, and the upper bottom panel 5 is provided with an upper through hole 51 aligned with the lower through hole 11. In actual application, the canned product unit can be placed in the receiving space, and the top panel 3, the upper bottom panel 5, the left panel 2 and the right panel 4 can respectively abut the top, bottom and opposite sides of the canned product unit; the consumer's line of sight can pass through the lower through hole 11 and the upper through hole 51 in turn to observe the product information such as production date, shelf life, etc. marked on the bottom of each canned product; the consumer can also insert his fingers into the lower through hole 11 and the upper through hole 51 in turn to lift the bundle packaging box and the canned product unit in the bundle packaging box. At this time, the lifting force applied by the consumer will be borne jointly by the lower bottom panel 1 and the upper bottom panel 5. It can be seen that if the canned product unit needs to be transported (that is, the cluster packaging box needs to be carried and moved), the consumer can insert his fingers into the lower through hole 11 on the lower bottom panel 1 and the upper through hole 51 on the upper bottom panel 5 in turn, and then the cluster packaging box can be lifted and moved. In the process of the consumer lifting the cluster packaging box, the lifting force applied by the consumer is always borne by the two layers of panels (that is, the lower bottom panel 1 and the upper bottom panel 5). This double-panel force-bearing method is more stable and will not break as easily as the handle of the traditional solution, thereby reducing the risk of the cluster packaging box falling and improving the stability of the cluster packaging box in the hand-carrying scenario, thereby ensuring the consumer's shopping experience; in addition, the present application integrates the hand-carrying function of the cluster packaging box with the function of observing the canned product related information (both achieved through the lower through hole 11 and the upper through hole 51), so there is no need to set an additional handle on the cluster packaging box, thereby reducing the production process of the cluster packaging box and improving the production efficiency of the cluster packaging box.
