[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] In the description of the embodiments of the present utility model, the terms "first", "second", "third", "fourth", and "fifth" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "third", "fourth", and "fifth" may explicitly or implicitly include one or more of the features.

[0028] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0029] In the description of the embodiments of the present invention, the term "plurality" refers to two or more than two. Moreover, when "plurality" is used to express the number of different components, it does not indicate the relationship between the components in terms of quantity.

[0030] In the description of the embodiments of the present utility model, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0031] Please refer to Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the structure of the multifunctional paper packaging box provided by the utility model in an unfolded state; Figure 2 This is a structural diagram of the multifunctional packaging box provided by the utility model in an assembled state, wherein the two third plate parts are both in the first position; Figure 3 This is a structural diagram of the multifunctional packaging box provided by the utility model in an assembled state, wherein a third plate portion is in the second position.

[0032] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a multifunctional paper packaging box, including a box body, which can be formed by folding a piece of packaging paper. In this way, the molding of the box body does not involve the splicing of multiple separate papers, so that the molding process of the box body can be relatively simple and the molding efficiency can be high.

[0033] Here, the embodiment of the utility model does not limit the specific type of the above-mentioned wrapping paper. In practical applications, those skilled in the art can select it according to specific needs. For example, the wrapping paper can be cardboard, kraft paper, etc.

[0034] In the embodiment of the utility model, the box body can be roughly in the shape of a cuboid, including a top plate B, a bottom plate A and a peripheral side plate, and the peripheral side plate is used to connect the top plate B and the bottom plate A. The peripheral side plate can specifically include four plate bodies, namely two first side plates 1 arranged opposite to each other, and two second side plates 2 arranged opposite to each other, and the two first side plates 1 and the two second side plates 2 are alternately arranged in the circumferential direction and connected in sequence.

[0035] The two first side plates 1 are both connected to the first extension plate 3. Figure 1 The first extension plate 3 includes a first plate portion 31, a second plate portion 32 and a third plate portion 33 which are connected in sequence.

[0036] The first plate portion 31 is connected to the first side plate 1, and the first plate portion 31 can be turned over relative to the first side plate 1. In this way, when the two first side plates 1 are arranged opposite to each other, the two first plate portions 31 can be turned over to be connected, specifically, the ends of the two first plate portions 31 away from the first side plates 1 can be connected, and the two connected first plate portions 31 can be combined to form a first butt-jointed plate portion, and the aforementioned bottom plate A includes the first butt-jointed plate portion.

[0037] The second plate portion 32 can be flipped relative to the first plate portion 31. When the two first plate portions 31 are connected, the two second plate portions 32 can be flipped to fit together to form a first partition plate C. The first partition plate C and the bottom plate A are set at an angle, and the angle can be, for example, 90 degrees. In practical applications, the two second plate portions 32 can be glued to ensure that the two second plate portions 32 can fit more closely, and the close fit of the two second plate portions 32 can also ensure the close connection of the two first plate portions 31. It should be understood that the tightness of the fit between the two second plate portions 32 can also be improved by other means, and the details can be referred to the relevant description below.

[0038] After the first partition plate C is formed, the first partition plate C, the two first side plates 1 and the two second side plates 2 can be enclosed to form two openings E of the box body, and the internal space of the box body can also be divided into two accommodating chambers by the first partition plate C, which can also realize the partitioning of the interior of the box body and can conveniently realize the partitioned storage of multiple items.

[0039] The third plate portion 33 is provided with an easy-to-break mark 33a distributed along a preset annular track, and the easy-to-break mark 33a can enclose the easy-to-break portion 33b in the third plate portion 33. It should be understood that the easy-to-break mark 33a in the embodiment of the utility model includes a plurality of cut-formed slits, and each slit can be arranged at intervals along the preset annular track, and there is an uncut connection between two adjacent slits. Because of the existence of these connection parts, the easy-to-break portion 33b can be stably placed in the third plate portion 33, which can ensure the integrity of the third plate portion 33. And because of the existence of the slits, when the easy-to-break portion 33 is subjected to external force, the uncut connection part in the easy-to-break mark 33a will also be easily broken, thereby causing the easy-to-break portion 33 to be separated from the third plate portion 33. After the easy-to-break portion 33b and the third plate portion 33 are separated, a hollow hole 33c will be formed at the position of the third plate portion 33 that originally belonged to the easy-to-break portion 33b.

[0040] Here, the embodiment of the utility model does not limit the specific shape of the preset annular track, that is, it does not limit the shape of the breakable portion 33b and the hollow hole 33c. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the preset annular track can be an oblong hole track (such as Figure 1-Figure 3 As shown), elliptical hole trajectory, rectangular hole trajectory, etc.

[0041] The third plate portion 33 can be turned over relative to the second plate portion 32 to switch between the first position and the second position.

[0042] In the first position, Figure 2As shown, the two third plates 33 can respectively block the two openings E, and the two third plates 33 can be combined to form the top plate B of the box body. At this time, the box body can have relatively good airtightness, and the multifunctional paper packaging box provided by the embodiment of the utility model can better play its storage and protection functions for articles.

[0043] In the second position, Figure 3 As shown, the third plate portion 33 can be flipped relative to the second plate portion 32 to expose the corresponding opening E. At this time, the type of items inside the box body can be well observed through the corresponding opening E, and the multifunctional paper packaging box provided by the embodiment of the utility model can also play the function of displaying items. In specific practice, both third plate portions 33 can be switched to the second position, or only one of the third plate portions 33 can be switched to the second position, which is not clearly limited here.

[0044] Furthermore, when the third plate portion 33 is in the second position, the breakable portion 33b can be separated from the third plate portion 33, so that the aforementioned hollow hole 33c can be formed on the third plate portion 33, and the user's finger can be inserted into the hollow hole 33c. In other words, the third plate portion 33 can also be used as a handle to facilitate the user to take it.

[0045] In this way, the paper packaging box provided in the embodiment of the utility model can achieve both storage and protection of articles and display of articles by adjusting the position of the third plate portion 33. At the same time, the third plate portion 33 located at the second position can also serve as a handle, which can facilitate the taking and carrying of the box body, and the functions are more diversified.

[0046] In some optional implementations, the third board portion 33 may include a first sub-board portion 331 and a second sub-board portion 332 .

[0047] The first sub-plate portion 331 can be connected to the second plate portion 32 and can be turned over relative to the second plate portion 32. The second sub-plate portion 332 can be turned over relative to the first sub-plate portion 331. The first sub-plate portion 331 and the second sub-plate portion 332 can both be provided with the above-mentioned easy-breaking marks 33a, and correspondingly, the first sub-plate portion 331 and the second sub-plate portion 332 can also be formed with the above-mentioned easy-breaking portions 33b. In the second position, the second sub-plate portion 332 can be turned over to fit with the first sub-plate portion 331. At this time, the easy-breaking portions 33b of the first sub-plate portion 331 and the easy-breaking portions 33b of the second sub-plate portion 332 can at least partially overlap, that is, after the easy-breaking portions 33b of the two are separated, the hollow holes 33c of the first sub-plate portion 331 and the hollow holes 33c of the second sub-plate portion 332 can at least partially overlap, so that the two hollow holes 33c can be connected to facilitate the user's finger to be inserted.

[0048] In this implementation, the third plate portion 33 serving as a handle actually includes two plate layers, namely a first sub-plate portion 331 and a second sub-plate portion 332 . The overall structural strength can be relatively high and is not easily damaged during use.

[0049] Still Figure 1 As shown, combined with Figure 3 The second plate portion 32 may include a main body portion 32a and a flange portion 32b. The main body portion 32a and the flange portion 32b may be formed by cutting the second plate portion 32, wherein the flange portion 32b is not cut off as a whole and is still connected to the main body portion 32a. In this way, under the action of an external force, the flange portion 32b can be flipped to a certain extent relative to the main body portion 32a at the connection between the two, and when the external force disappears, the flange portion 32b can rebound and reset by relying on its own elasticity.

[0050] Based on this structural design, in the second position, part of the second sub-board portion 332 can be inserted between the flange portion 32b and the main body portion 32a so that the second sub-board portion 332 can be clamped by means of the elasticity of the flange portion 32b itself, thereby improving the reliability of the fit between the second sub-board portion 332 and the first sub-board portion 331 in the second position.

[0051] Here, the embodiment of the utility model does not limit the number of flange portions 32b. In practical applications, those skilled in the art can set them according to specific needs as long as they can meet the requirements of use. Figure 1 and Figure 3 In the implementation manner, each second plate portion 32 may be provided with two flange portions 32b, and in some other implementation manners of the embodiment of the utility model, the flange portions 32b provided on each second plate portion 32 may also be other numbers.

[0052] In some optional implementations, the third plate portion 33 may also be provided with a first folded edge portion 332a at one end away from the second plate portion 32. Based on the aforementioned implementation in which the third plate portion 33 includes a first sub-plate portion 331 and a second sub-plate portion 332, the first folded edge portion 332a here actually belongs to the second sub-plate portion 332.

[0053] In the first position, the first folded edge portion 332a can be inserted into the opening E and can fit with the first side plate 1 provided with the first extension plate 3, so as to better achieve reliable blocking of the opening E. Correspondingly, in the second position, the second sub-plate portion 332 can be inserted between the flange portion 32b and the main body portion 32a through the first folded edge portion 332a.

[0054] In some optional implementations, both second side panels 2 may be connected to a second extension panel 4 , and the second extension panel 4 may include a fourth panel portion 41 , and the fourth panel portion 41 may be flipped relative to the second side panel 2 .

[0055] In this way, when the two second side panels 2 are arranged opposite to each other, the two fourth panel portions 41 can be flipped to be connected, specifically, the ends of the two fourth panel portions 41 away from the second side panels 2 can be connected, and the two connected fourth panel portions 41 can be combined to form a second docking panel portion. The aforementioned bottom panel A can also include the second docking panel portion, and the second docking panel portion can be located at the lower side of the first docking panel portion. In other words, the bottom panel A can also adopt a double-layer panel structure, which is also conducive to ensuring the structural strength of the bottom panel A, and thus can improve the structural strength of the box body.

[0056] Furthermore, the second extension plate 4 may also include a fifth plate portion 42, which may be connected to the fourth plate portion 41, and the fifth plate portion 42 may be flipped relative to the fourth plate portion 41, and the two fifth plate portions 42 may be flipped to fit together to form a second partition plate D. The second partition plate D and the bottom plate A may be arranged at an angle, which may be, for example, 90 degrees. In practical applications, the two fifth plate portions 42 may be glued to ensure that the two fifth plate portions 42 can fit more closely, and the close fit of the two fifth plate portions 42 can also ensure the close connection of the two fourth plate portions 41.

[0057] Still Figure 1 As shown, the first plate portion 31 can also be provided with a first avoidance slit 311, and the second plate portion 32 can be provided with a second avoidance slit 321a. The first plate portion 31 can be inserted into the second partition plate D through the first avoidance slit 311, so that the first plate portion 31 will not interfere with the second partition plate D during the process of flipping to form the first docking plate portion. The second plate portion 32 can be plugged into the second partition plate D through the second avoidance slit 321a, so that the second plate portion 32 will not interfere with the second partition plate D during the process of flipping to form the first partition plate C; and the plate body located on both sides of the second avoidance slit 321a in the second plate portion 32 can actually clamp the two fifth plate portions 42, which can effectively improve the tightness of the fit between the two fifth plate portions 42. In this case, no adhesive may be provided between the two fifth plate portions 42.

[0058] Combination Figure 3 After the first partition plate C and the second partition plate D are formed, the internal space of the box body can be divided into four accommodating chambers, which allows more partitions to be formed inside the box body and can better realize the partitioned storage of multiple items.

[0059] In addition, when the third plate portion 33 is in the first position, the aforementioned first folded edge portion 332a can be specifically located between the second partition plate D and the first side plate 1, and can be clamped by the second partition plate D and the first side plate 1, which is beneficial to ensure that the third plate portion 33 can be stably in the above-mentioned first position, that is, the opening E can be better sealed.

[0060] Combination Figure 1 In the arrangement direction of the first plate portion 31 , the second plate portion 32 and the third plate portion 33 , the first avoidance groove 311 penetrates the first plate portion 31 , so that the first plate portion 31 can completely avoid the second partition plate D.

[0061] As for the second avoidance gap 321a, it may include the following two solutions.

[0062] In one solution, the second avoidance groove 321 a may completely penetrate the second plate portion 32 , so as to better achieve complete avoidance of the second partition plate D.

[0063] In another embodiment, the second avoidance groove 321a may not completely penetrate the second plate portion 32. At this time, for the convenience of description, the second plate portion 32 may be divided into a third sub-plate portion 321 and a fourth sub-plate portion 322 along the extension direction of the second avoidance groove 321a. The second avoidance groove 321a may completely penetrate the third sub-plate portion 321, but may not extend to the fourth sub-plate portion 322; that is, the fourth sub-plate portion 322 may not be provided with the second avoidance groove 321a. Figure 1 In this scheme, a notch 421 may be further provided at one end of the fifth plate portion 42 away from the fourth plate portion 41 , and the third sub-plate portion 321 may be plugged into the second partition plate D through the second avoidance gap 321a, and at the same time, the fourth sub-plate portion 322 may be plugged into the notch 421 .

[0064] It should be understood that the notch 421 can have a limiting function, which can improve the tightness of the two second plate portions 32 so that no adhesive is required between the two second plate portions 32, and can also limit the position of the first partition plate C relative to the second partition plate D. In addition, when the third plate portion 33 is in the second position, the second sub-plate portion 332 can also be inserted into the notch 421, and cooperate with the aforementioned flange portion 32b, so as to better achieve the clamping between the second sub-plate portion 332 and the first sub-plate portion 331.

[0065] Furthermore, the fifth plate portion 42 may be provided with a third avoidance slit 422 connected to the notch 421, and part of the fourth sub-plate portion 322 may be plugged into the third avoidance slit 422. In this way, the plate body of the fifth plate portion 42 located on both sides of the third avoidance slit 422 may actually clamp the two second plate portions 32, which may also improve the tightness of the fit between the two second plate portions 32, thereby reducing the setting of the adhesive.

[0066] like Figure 1 As shown, one of the two first side panels 1 and the two second side panels 2 located at the edge may be provided with a second folded edge portion 11, and the second folded edge portion 11 is used to connect the first side panels 1 and the second side panels 2 adjacent to each other in the circumferential direction, and the specific connection method may be bonding, etc. In this way, the two first side panels 1 and the two second side panels 2 can be connected to form a complete circumferential side panel.

[0067] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
