Description

Technical Field

[0001] This application relates to the field of material packaging technology, and in particular to a packaging structure. Background Technology

[0002] As the international community places increasing emphasis on environmental protection, more and more products are gradually abandoning plastic bags for packaging and instead adopting more environmentally friendly materials, such as corrugated cardboard boxes.

[0003] Currently, most products have labels to distinguish product type or size. Typically, part of the label is affixed to the product, while the rest is exposed for easy viewing or removal. However, during the packaging process, the label can interfere with the cardboard, causing wrinkles and negatively impacting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a packaging structure that can solve the problem of existing cardboard packaging boxes easily interfering with product labels, causing the product labels to wrinkle.

[0005] According to one aspect of this application, a packaging structure is provided, comprising:

[0006] Intermediate plate;

[0007] Multiple side panels are integrally connected to the four edges of the middle panel. Each side panel is connected to the middle panel to form a first fold line. The first fold line is configured to allow the side panels to be easily folded toward the middle panel so that all the side panels can be together with the middle panel to form a packaging box with a receiving cavity.

[0008] At least one of the enclosure panels has a clearance hole, which is used to allow a label affixed to the product to pass through when the enclosure panel and the intermediate panel form the packaging box and the product is contained in the receiving cavity of the packaging box.

[0009] In one embodiment, the plurality of enclosure panels include at least one first enclosure panel, the first enclosure panel having a plurality of second fold lines that are parallel to and spaced apart from the first fold line, the second fold lines dividing a single first enclosure panel into a plurality of enclosure portions;

[0010] When the first enclosure panel is folded sequentially along each of the second fold lines toward the direction of the middle panel, and the enclosure portion away from the middle panel among the plurality of enclosure portions formed by the single first enclosure panel is connected end to end with the enclosure portion near the middle panel, the plurality of enclosure portions can form a hollow buffer liner, one of the enclosure portions constitutes the inner sidewall of the packaging box, and the other enclosure portion constitutes the outer sidewall of the packaging box, and the clearance hole is opened on the enclosure portion used to constitute the inner sidewall of the packaging box.

[0011] In one embodiment, among the plurality of enclosures formed by a single first enclosure plate, the edge of the enclosure away from the intermediate plate has a positioning protrusion, and the first or second enclosure near the intermediate plate has a positioning groove for inserting the positioning protrusion.

[0012] In one embodiment, the plurality of enclosure portions formed by a single first enclosure plate include: a first enclosure portion, a second enclosure portion, a third enclosure portion, a fourth enclosure portion, and a fifth enclosure portion arranged sequentially from the direction away from the intermediate plate. The second enclosure portion is used to form the outer sidewall of the packaging box, the fourth enclosure portion is used to form the inner sidewall of the packaging box, the positioning protrusion is provided on the edge of the fifth enclosure portion, and the positioning groove is formed on the second enclosure portion.

[0013] In one embodiment, in the direction from the first enclosure portion to the fifth enclosure portion, the dimensions of the first enclosure portion, the third enclosure portion, and the fifth enclosure portion are equal and defined as a first dimension, and the dimensions of the second enclosure portion and the fourth enclosure portion are equal and defined as a second dimension, wherein the first dimension is smaller than the second dimension;

[0014] When the first enclosure, the second enclosure, the third enclosure, the fourth enclosure, and the fifth enclosure form the buffer liner, the second enclosure and the fourth enclosure are arranged at a distance from each other, the third enclosure and the fifth enclosure are arranged at a distance from each other, and the fifth enclosure is attached to the first enclosure.

[0015] In one embodiment, the plurality of side panels further includes a second side panel integrally connected to a first top panel. The first top panel and the second side panel are connected on one side to form a third fold line. The third fold line is configured to allow the first top panel to be easily folded toward the middle panel so that the first top panel can form the top wall of the packaging box.

[0016] In one embodiment, the edge of the first top plate is provided with a tongue, and the first enclosure plate is provided with a slot for the tongue to be inserted when the first enclosure plate forms the buffer liner.

[0017] In one embodiment, the edge of the first top plate protrudes from the edge of the second enclosure relative to the same side, such that when the first top plate is folded along the third fold line toward the middle plate, the first top plate can cover and conform to the top surface of the cushioning liner.

[0018] In one embodiment, the edge of the first top plate is provided with a handle groove.

[0019] In one embodiment, the plurality of side panels further includes a third side panel disposed opposite to the second side panel. The third side panel is integrally connected to the second top panel. The side of the second top panel connected to the third side panel forms a fourth fold line. The fourth fold line is configured to allow the second top panel to be easily folded toward the middle panel, so that when the first top panel is constructed to form the top wall of the packaging box, the second top panel can fit against the inside of the first top panel.

[0020] The above-mentioned packaging structure, on the one hand, connects the middle plate and multiple side plates as a whole, with each side plate forming a first fold line on the side connected to the middle plate. This allows each side plate to be folded along the first fold line to form a packaging box with a receiving cavity. As a result, the packaging structure is simple, without too many parts. Before being assembled into a packaging box, it is just a piece of cardboard, which does not take up much space and is easy to assemble.

[0021] On the other hand, by providing clearance holes in at least one of the side panels, the label affixed to the product can pass through the clearance holes when the side panels and the middle panel form a packaging box and the product is contained in the receiving cavity of the packaging box. Therefore, when packaging the product using the packaging structure provided in this application, the problem of labels easily interfering with the cardboard and causing label wrinkles is solved.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] One embodiment of this application provides a packaging structure that can be formed by folding a cardboard sheet. This packaging structure is used to wrap a product, thereby protecting the product during handling or transportation to prevent damage.

[0037] The structure of the packaging structure in this application is described below. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the packaging structure of this application can be used to package any product, and no limitation is made here.

[0038] See Figure 1 , Figure 1 This is a top view of the packaging structure 10 of an embodiment of the present application in its unfolded state. Figure 2 This is a perspective view of the packaging structure 10 in the unfolded state according to this embodiment. Figure 3 A schematic diagram of the packaging structure 10 in the molding state of this embodiment is shown. An embodiment of the packaging structure 10 provided in this application includes a middle plate 100 and multiple side plates 200 integrally connected to the four edges of the middle plate 100. In the embodiment shown in the above figure, both the middle plate 100 and the side plates 200 have a quadrilateral structure. Each side plate 200 connected to the middle plate 100 forms a first fold line 11. The side plates 200 can be easily folded along the first fold line 11 towards the middle plate 100, so that all the side plates 200 can be together with the middle plate 100 to form a packaging box with a receiving cavity. When the side plates 200 and the middle plate 100 together form the packaging box, the packaging structure 10 is in the molding state. Figure 3 The forming state shown.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the aforementioned multiple enclosure panels 200 include a first enclosure panel 210, a second enclosure panel 220, and a third enclosure panel 230. In the embodiment shown in the figure, there are two first enclosure panels 210, which are arranged opposite each other along the X direction shown in the figure. The second enclosure panel 220 and the third enclosure panel 230 are arranged opposite each other along the Y direction, which is perpendicular to the X direction shown in the figure. After the two first enclosure panels 210, the second enclosure panel 220, and the third enclosure panel 230 are folded along their respective first fold lines 11 toward the direction closer to the middle panel 100, they together with the middle panel 100 form a packaging box. The middle panel 100 constitutes the bottom wall of the packaging box, and the two first enclosure panels 210, the second enclosure panel 220, and the third enclosure panel 230 respectively constitute the four side walls of the packaging box.

[0040] In the embodiment shown in the figure, the second enclosure 220 and the third enclosure 230 have the same structure and size, both being rectangular. The first enclosure 210 has a different structure from the second enclosure 220 and the third enclosure 230. The structure of the first enclosure 210 will be described in detail below.

[0041] like Figure 3 and Figure 4As shown, the first panel 210 has multiple second fold lines 12 that are parallel to and spaced apart from the first fold line 11. The second fold lines 12 divide the single first panel 210 into multiple enclosure portions 211. When the first panel 210 is folded sequentially along each of the second fold lines 12 toward the direction closer to the middle panel 100, and the multiple enclosure portions 211 formed by the single first panel 210 are connected end to end, the multiple enclosure portions 211 can form a double-layer hollow buffer liner 240. One enclosure portion 211 serves as the inner layer of the buffer liner 240, constituting the inner sidewall of the packaging box, and the other enclosure portion 211 serves as the outer layer of the buffer liner 240, constituting the outer sidewall of the packaging box.

[0042] Thus, by enabling the first enclosure 210 to form a buffer liner 240, when the product 30 is wrapped in the receiving cavity, even if the product 30 is squeezed or the outer wall of the packaging structure 10 is hit, the product 30 will not be violently impacted because the buffer liner 240 has a hollow structure inside. Therefore, the product 30 can be effectively protected and prevented from being damaged.

[0043] More specifically, in a preferred embodiment, each first enclosure 210 has four second fold lines 12, which divide a single enclosure 200 into five enclosure portions 211. The five enclosure portions 211 are a first enclosure portion 212, a second enclosure portion 213, a third enclosure portion 214, a fourth enclosure portion 215, and a fifth enclosure portion 216. In the X direction away from the intermediate plate 100, the first enclosure portion 212, the second enclosure portion 213, the third enclosure portion 214, the fourth enclosure portion 215, and the fifth enclosure portion 216 are arranged sequentially. The first enclosure portion 212 is used to form the bottom wall of the packaging box together with the intermediate plate 100. The second enclosure portion 213 is used as the inner layer of the cushioning liner 240 to form the outer wall of the packaging box. The fourth enclosure portion 215 is used as the outer layer of the cushioning liner 240 to form the inner wall of the packaging box.

[0044] Furthermore, in the direction from the first enclosure 212 to the fifth enclosure 216, the dimensions of the first enclosure 212, the third enclosure 214, and the fifth enclosure 216 are equal and defined as a first dimension, and the dimensions of the second enclosure 213 and the fourth enclosure 215 are equal and defined as a second dimension, with the first dimension being smaller than the second dimension. When the first enclosure 212, the second enclosure 213, the third enclosure 214, the fourth enclosure 215, and the fifth enclosure 216 form a buffer liner 240, the second enclosure 213 and the fourth enclosure 215 are spaced apart relative to each other, the third enclosure 214 and the fifth enclosure 216 are spaced apart relative to each other, and the fifth enclosure 216 is attached to the first enclosure 212.

[0045] Thus, it can be seen that, through the above design, the buffer liner 240 formed by each enclosure 211 has a regular shape, which can not only provide buffer protection for the product 30, but also enhance the aesthetics of the packaging structure 10.

[0046] Furthermore, to facilitate the connection of the multiple enclosure portions 211 of the single first enclosure panel 210 end to end, please refer to [further details needed]. Figure 4 In the plurality of enclosure portions 211 formed by the single first enclosure plate 210, the edge of the enclosure portion 211 away from the intermediate plate 100 has a positioning protrusion 2161, and a positioning groove 2131 is formed near the first enclosure portion 211 or the second enclosure portion 211 of the intermediate plate 100. The positioning groove 2131 is used for the positioning protrusion 2161 to be inserted. For example, in Figure 4 In the embodiment, the positioning protrusion 2161 is disposed on the edge of the fifth enclosure 216, and the positioning groove 2131 is formed in the second enclosure 213 near the first enclosure 212. This, combined with... Figure 5 As shown, when multiple enclosures 211 form a buffer liner 240, the fifth enclosure 216 can be connected to the second enclosure 213 by means of a positioning protrusion 2161 inserted into the positioning groove 2131, thereby preventing the fifth enclosure 216 from falling off the second enclosure 213 and thus preventing the buffer liner 240 from loosening. Furthermore, compared with bonding or other connection methods, the method of inserting the positioning protrusion 2161 into the positioning groove 2131 does not require other tools, making it easier to assemble the packaging box.

[0047] It is understandable that the positioning groove 2131 can also be formed on the first enclosure 212, and the fifth enclosure 216 can also be attached to the first enclosure 212 or the second enclosure 213, without limitation.

[0048] It is also understandable that the number of second fold lines 12 on the first panel 210 is unlimited, and therefore the number of enclosing parts 211 is also unlimited, as long as they can form a buffer liner 240.

[0049] In other embodiments, the surrounding panels 200 connected around the middle plate 100 can all be the first surrounding panels 210, that is, the surrounding panels 200 connected around the middle plate 100 can all form the buffer liner 240, or there can be only one or any number of surrounding panels 200 as the first surrounding panels 210, which is not limited here.

[0050] Furthermore, as described in the background section, most products have labels affixed to distinguish product type or size. Typically, part of the label is affixed to the product, while the remainder is exposed for easy viewing or removal. However, during the packaging process, the label can easily interfere with the cardboard, causing it to wrinkle and negatively impacting the user experience.

[0051] Therefore, in order to solve this problem, such as Figure 4 and Figure 5 As shown, as an improvement to the above embodiment, the fourth enclosure portion 215 is provided with a plurality of clearance holes 2151 penetrating the fourth enclosure portion 215. The clearance holes 2151 are used for the label 31, which is affixed to the product 30 and exposed on the product 30, to pass through when the enclosure plate 200 and the middle plate 100 form a receiving cavity and the product 30 is received in the receiving cavity. In this way, after folding the first enclosure plate 210 to form the buffer liner 240 and then folding it along the first fold line 11, so that the buffer liner 240 is folded relative to the middle plate 100 to form a packaging box and package the product 30, as long as the label 31 of the product 30 passes through the clearance groove, it can be received in the hollow cavity of the buffer liner 240. Therefore, interference between the label 31 and the side wall of the packaging structure 10 can be avoided, and wrinkles on the label 31 can be avoided. Furthermore, since there is also an outer side wall of the buffer liner 240 (i.e. Figure 4 The second enclosure 213 in the packaging structure 10 covers the label 31, so that objects outside the packaging structure 10 will not touch the label 31 and will not damage the label 31.

[0052] Of course, the clearance hole 2151 can also be made on the second enclosure 220 and / or the third enclosure 230, or all the enclosures 200 connected to the intermediate plate 100 can be the same as the second enclosure 220 or the third enclosure 230, which can only form a single-layer sidewall. The clearance hole 2151 is made on the enclosure 200 of this type. However, it is obvious that making the clearance hole 2151 on the enclosure 200 used to form the inner sidewall of the buffer liner 240 can better protect the label 31, which is obviously the best embodiment.

[0053] Please continue reading. Figures 1 to 3 When the partition panels 200 and the middle panel 100 form a receiving cavity, in order to close the upper opening of the receiving cavity, the second partition panel 220 is integrally connected to the first top panel 250. The first top panel 250 and the second partition panel 220 are connected on one side to form a third fold line 13. The first top panel 250 can be easily folded along the third fold line 13 towards the middle panel 100 so that the first top panel 250 can close the top opening of the receiving cavity and form the top wall of the packaging box. That is, one side of the first top panel 250 can serve as the outer side of the top wall of the packaging box.

[0054] When the first top plate 250 forms the top wall of the packaging box and closes the top opening of the receiving cavity, in order to prevent the first top plate 250 from automatically flipping upward in a direction away from the middle plate 100, the first top plate 250 along... Figure 1 Tongues 251 are provided on both ends of the edge in the X direction, correspondingly, as follows: Figure 4 As shown, a slot 2132 is provided on the second enclosure portion 213 of the first enclosure 210. When the first top plate 250 is constructed as the top wall of the packaging box and the first enclosure 210 forms a buffer liner 240, the tongue 251 can be inserted into the slot 2132, thereby locking the first enclosure 210 onto the buffer liner 240 to achieve sealing. Compared with the traditional method of sealing with glue or tape, it is easier to operate.

[0055] Based on the above embodiments, preferably, the first top plate 250 along... Figure 1 Each edge at both ends in the X direction protrudes from the corresponding edge on the same side of the second enclosure 220 in the X direction, so that when the first top plate 250 is folded along the third fold line 13 toward the direction closer to the middle plate 100, the first top plate 250 can cover and fit the top surface of the cushioning liner 240 (i.e., cover and fit the third enclosure portion 214 of the first enclosure 210), thereby ensuring the consistency of the dimensions of the top and bottom walls of the packaging box and the overall aesthetics when the packaging structure 10 is formed into a packaging box.

[0056] In a preferred embodiment, the first top plate 250 along Figure 1 A hand-holding groove 252 is provided on the edge of the first top plate 250 in the Y direction away from the second enclosure 220. The purpose of providing the hand-holding groove 252 is to give the user a clear tactile sensation when touching the first top plate 250, such as... Figure 3 As shown, when the first top plate 250 is constructed to form the top wall of the packaging box, it is easy for the user to hold the first top plate 250 and flip it up in a direction away from the middle plate 100 so that the first top plate 250 is restored from the folded state to the unfolded state relative to the second side plate 220.

[0057] It should be noted that the first top plate 250, due to its relatively thin thickness, may not be sufficient to provide adequate protection for the top of the product 30. Therefore, further, such as Figure 1 and Figure 2As shown, the third enclosure 230 is integrally connected to the second top plate 260. The side where the second top plate 260 is connected to the third enclosure 230 forms a fourth fold line 14. The second top plate 260 can be easily folded towards the middle plate 100 along the fourth fold line 14, so that when the first top plate 250 is constructed to form the top wall of the packaging box, the second top plate 260 can fit against the inner side of the first top plate 250. Thus, when the second top plate 260 fits against the first top plate 250, the side of the second top plate 260 away from the first top plate 250 is constructed as the top wall of the receiving cavity. This makes the top wall of the packaging box a double-layer structure, increasing its thickness. When the product 30 is contained in the receiving cavity, the top of the packaging box can withstand impact, thus providing better protection for the product 30 from the top.

[0058] Therefore, the packaging structure 10 provided in this application has a simple structure with few parts. Before being assembled into a packaging box, the packaging structure 10 is just a piece of cardboard, which does not take up much space and is easy to assemble. After being assembled into a packaging box, the packaging box has a cushioning liner 240, which not only ensures the strength of the packaging box, but also provides good protection for the product 30. Moreover, the inner side wall of the cushioning liner 240 has a clearance hole 2151, which solves the problem that the label 31 of the product 30 is prone to interference with the cardboard during the packaging process, resulting in wrinkles or damage to the label 31.

[0059] In addition, when it is necessary to store multiple boxes formed by 10 folds of multiple packaging structures, such as Figure 6 As shown, a larger cardboard box 40 can also be folded to form a larger outer packaging box 40, allowing multiple boxes to be placed inside for easier packaging and transportation. The outer packaging box 40 formed by folding the cardboard can be of any structure; various existing packaging box structures are available and will not be elaborated upon here. For example… Figure 6 As shown, after the packaging structure 10 is formed into a packaging box and the cardboard is formed into an outer packaging box 40, two packaging boxes are placed at the bottom of the outer packaging box 40, and then two more packaging boxes are placed at the top of the outer packaging box 40, so that one outer packaging box 40 can hold four packaging boxes at a time, thereby enabling the batch transportation and protection of multiple packaging boxes.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
