[0031] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] To solve the technical problem that existing packaging does not provide good protection for products, such as Figure 4 As shown, the present application proposes a package 100, which includes an annular sleeve 10, which is folded from a cardboard 300 and includes a plurality of side walls (i.e., a first side wall 11, a second side wall 12, a third side wall 13 and a fourth side wall 14), the plurality of side walls enclose a receiving space 20 for accommodating a product 200 to be packaged, and a portion of at least one side wall is folded into the receiving space 20 to form a retaining rib 30, and the retaining rib 30 is used to limit the product 200 to be packaged from leaving the receiving space 20 along the axial direction of the annular sleeve 10.

[0034] Specifically, in Figure 4 In the structural scheme shown, the shape of the package 100 is roughly a square ring structure, that is, the ring sleeve 10 has four side walls, and any two adjacent side walls of the four side walls are perpendicular to each other, which facilitates the placement and stacking of the package 100 after the product is packaged, saving transportation space.

[0035] Of course, in other embodiments, the shape of the package 100 may also be a hollow cylinder, elliptical cylinder, triangular prism, pentagonal prism, hexagonal prism, etc. The specific shape of the package 100 can be designed according to the shape of the product 200 to be packaged.

[0036] In order to better illustrate the technical concept of the present application, the present application specification takes the packaging 100 having a square ring shape as an example for description.

[0037] Please combine Figures 1 to 4 The annular sleeve 10 is formed by folding a piece of cardboard 300. The cardboard 300 includes four plates (i.e., a third plate 33, a second plate 32, a first plate 31, and a fourth plate 34) connected in sequence. A fold (i.e., a fourth fold 35) is provided between two adjacent plates. When folding, the cardboard 300 can be folded along the fold to form a square ring-shaped annular sleeve 10. Each plate on the cardboard 300 corresponds to a side wall of the annular sleeve 10.

[0038] It should be noted here that in order to prevent the paperboard 300 from automatically unfolding after being folded into the annular sleeve 10, after the paperboard 300 is folded into the annular sleeve 10, the two plates (i.e., the third plate 33 and the fourth plate 34) located at both ends of the paperboard 300 can be relatively fixed by bonding, clamping, etc., so that the annular sleeve 10 can be prevented from automatically unfolding, thereby improving the structural stability of the package 100.

[0039] like Figure 4 As shown, a plurality of side walls together enclose a receiving space 20, which is a square column-shaped cavity and is used to receive a product 200 to be packaged. The receiving space 20 can be configured to receive one product 200 to be packaged, or can be configured to receive a plurality of products 200 to be packaged. When the receiving space 20 is used to receive a plurality of products 200 to be packaged, the plurality of products 200 to be packaged can be arranged along the length direction of the receiving space 20, along the width direction of the receiving space 20, or along the height direction of the receiving space 20. In short, the placement of the plurality of products 200 to be packaged in the receiving space 20 can be flexibly designed as needed.

[0040] It can be understood that when the product 200 to be packaged is placed in the accommodating space 20, the multiple side walls of the annular sleeve 10 form a protection for the surrounding side of the product 200 to be packaged, thereby preventing foreign objects from hitting the product 200 to be packaged from the surrounding side of the product 200.

[0041] like Figures 2 to 3 As shown in any of the figures, in this embodiment, part of the wall of at least one side wall is folded into the accommodating space 20 to form a retaining rib 30, which is used to limit the product 200 to be packaged from leaving the accommodating space 20 along the axial direction of the annular sleeve 10.

[0042] Specifically, after the paperboard 300 is folded into the annular sleeve 10, the two ends of the annular sleeve 10 in the axial direction (i.e., the length direction in the figure) are respectively provided with openings 15, and the product 200 to be packaged may fall out of the accommodation space 20 through the openings 15. Therefore, in this embodiment, a part of the wall of at least one side wall is folded into the accommodation space 20 to form a retaining rib 30, and the retaining rib 30 is located on one side of the product 200 to be packaged along the axial direction of the annular sleeve 10, thereby not only preventing the product 200 to be packaged from leaving the accommodation space 20 through the opening 15, but also preventing foreign objects from hitting the product 200 to be packaged from the axial direction of the product, further improving the protective effect of the packaging 100 on the product 200 to be packaged.

[0043] It should be noted here that there can be many types of side walls that are partially folded to form the retaining rib 30 and the structure of the retaining rib 30. For example, in one embodiment, part of the wall of one of the side walls can be folded into the accommodating space 20. At this time, the retaining rib 30 is in a straight line shape, and one end of the retaining rib 30 is connected to the side wall where it is located, and the other end is fixed to the adjacent or opposite side wall.

[0044] For another example, part of the wall bodies of two side walls that are spaced opposite to each other may be folded into the accommodation space 20, and the retaining rib 30 may include two straight-line ribs, which may be parallel to each other, extend at an angle, or be connected to each other to form a longer straight-line rib that crosses to form an X shape. It should be noted that when the two straight-line ribs extend parallel to each other or at an angle, each straight-line rib is connected to the side wall where it is located at one end, and the other end is fixed to the adjacent or opposite side wall.

[0045] For another example, part of the wall bodies of two adjacent side walls may be folded into the accommodation space 20, and the retaining rib 30 may include two straight-line ribs, and the two straight-line ribs extend in different directions, for example, one straight-line rib extends in the width direction of the annular sleeve 10, and the other straight-line rib extends in the height direction of the annular sleeve 10. In addition, the two straight-line ribs may be cross-shaped or connected to each other to form a bent and extended retaining rib 30 structure.

[0046] On the basis of the above embodiments, each side wall may be partially folded into the accommodating space 20 , and the retaining ribs 30 are formed into a mesh structure by a plurality of parallel and / or cross ribs.

[0047] In summary, there can be many numbers of side walls formed by folding part of the wall body and structures of the retaining ribs 30 , which can be flexibly selected according to needs during specific implementation.

[0048] In summary, it can be understood that the packaging 100 of the present application is provided with an annular sleeve 10, which is folded from a paperboard 300 and includes a plurality of side walls, the plurality of side walls enclose a receiving space 20 for accommodating the product 200 to be packaged, and a portion of the wall of at least one side wall is folded into the receiving space 20 to form a retaining rib 30, and the retaining rib 30 is used to limit the product 200 to be packaged from escaping from the receiving space 20 along the axial direction of the annular sleeve 10. During packaging, the product 200 to be packaged can be placed in the receiving space 20 of the annular sleeve 10, and the retaining rib 30 limits the product 200 to be packaged from escaping from the receiving space 20, thereby preventing the product 200 to be packaged from falling out of the packaging 100, and thus better protecting the product 200 to be packaged. Because the package 100 of the present application is folded from cardboard 300, the package 100 is more environmentally friendly and easy to recycle; and because the multiple side walls and retaining ribs 30 of the package 100 confine the product 200 to be packaged within the accommodating space 20, it can not only provide better protection for the product 200 to be packaged, but also has a simple structure and low cost.

[0049] Optionally, in one embodiment, as Figure 2 or Figure 3 As shown, both ends of the annular sleeve 10 in the length direction are respectively provided with openings 15, the openings 15 are connected to the accommodating space 20, and a portion of the wall of at least one side wall is turned inwardly toward the accommodating space 20 at the opening 15 to form a retaining rib 30, and at this time, the product 200 to be packaged is located between the two retaining ribs 30 and cannot escape from the accommodating space 20 through the opening 15. That is, in this embodiment, the retaining rib 30 is formed at the opening 15 of the annular sleeve 10, and compared with the structural solution in which the retaining rib 30 is located in the accommodating space 20 and is spaced apart from the opening 15, this solution can reduce the length of the package 100, thereby saving transportation space and reducing transportation costs.

[0050] Optionally, in one embodiment, a plurality of blocking ribs 30 are provided, and the plurality of blocking ribs 30 are arranged at intervals along the length direction of the annular sleeve 10, and the space between two adjacent blocking ribs 30 is used to accommodate the product 200 to be packaged. Specifically, for example, three blocking ribs 30 may be provided, wherein two blocking ribs 30 are respectively located at the two openings 15, and one blocking rib 30 is located between the two openings 15, so that at least one product 200 to be packaged can be placed between each two adjacent blocking ribs 30, and the middle blocking rib 30 can limit the product 200 to be packaged from sliding in the accommodating space 20, so as to prevent the products 200 to be packaged from colliding with each other along the length direction of the annular sleeve 10.

[0051] Optionally, in one embodiment, as Figures 2 to 4As shown in any of the figures in the drawings, the plurality of side walls include a first side wall 11 and a second side wall 12 that are adjacently arranged, the first side wall 11 includes a first packaging wall body 111 and a first limiting wall body 112, and the second side wall 12 includes a second packaging wall body 121 and a second limiting wall body 122. The first limiting wall body 112 is folded inwardly toward the accommodation space 20 relative to the first packaging wall body 111, and the second limiting wall body 122 is folded inwardly toward the accommodation space 20 relative to the second packaging wall body 121, and the first limiting wall body 112 and the second limiting wall body 122 are connected to form a retaining rib 30, and the retaining rib 30 extends in a bent state.

[0052] Specifically, in this embodiment, Figure 4 The orientation indication in is used as a reference, the side where the third side wall 13 is located is the front side, and the side where the fourth side wall 14 is located is the upper side. The first side wall 11 is the rear side wall of the package 100, the first package wall 111 extends vertically, and the first limiting wall 112 is folded forward from the first package wall 111. The second side wall 12 is the bottom wall of the package 100, the second package wall 121 extends horizontally, and the second limiting wall 122 is folded upward from the second package wall 121. The end of the first limiting wall 112 away from the first package wall 111 is connected to the end of the second limiting wall 122 away from the second package wall 121, thereby forming a bent and extended retaining rib 30.

[0053] It can be understood that in this embodiment, two adjacent side walls are partially folded into the accommodating space 20 and connected to form a bent and extended retaining rib 30. This not only forms a barrier in the height direction and the width direction at the same time, making it difficult for the packaged product 200 to escape from the accommodating space 20 through the opening 15, but also does not need to set a positioning structure on the other side walls to fix the first limiting wall 112 and the second limiting wall 122. The first limiting wall 112 and the second limiting wall 122 can be fixed by being connected to each other, thereby simplifying the structure of the package 100.

[0054] It should be noted that the angle between the first limiting wall 112 and the second limiting wall 122 can be an acute angle, a right angle or an obtuse angle. Figure 4 As shown, the first packaging wall 111 and the second limiting wall 122 both extend in the height direction of the annular sleeve 10, and the second packaging wall 121 and the first limiting wall 112 both extend in the width direction of the annular sleeve 10, that is, in this embodiment, the angle between the first limiting wall 112 and the second limiting wall 122 is a right angle, which can make the structural strength of the retaining rib 30 better and reduce the deformation of the retaining rib 30 due to shaking and the like.

[0055] In addition, it should be noted that the first limiting wall 112 and the second limiting wall 122 can be connected to each other by bonding, clamping, etc., for example, optionally, please combine Figure 1 and Figure 4 In one embodiment, the first limiting wall 112 and the second limiting wall 122 are integrally connected, and a third fold 18 is provided between the first limiting wall 112 and the second limiting wall 122 .

[0056] Specifically, in this embodiment, if Figure 1 As shown, the paperboard 300 used to fold into the annular sleeve 10 includes a third plate 33, a second plate 32, a first plate 31 and a fourth plate 34 connected in sequence, and a fourth fold 35 is provided between the third plate 33 and the second plate 32, between the second plate 32 and the first plate 31, and between the first plate 31 and the fourth plate. After the paperboard 300 is folded along the fourth fold 35, the first plate 31 forms the first side wall 11, the second plate 32 forms the second side wall 12, the third plate 33 forms the third side wall 13, and the fourth plate forms the fourth side wall 14.

[0057] like Figure 1 As shown, the first plate body 31 includes a first packaging plate body 311 and a first limiting plate body 312. The first limiting plate body 312 can be folded relative to the first packaging plate body 311. After folding, the first packaging plate body 311 forms the first packaging wall body 111, and the first limiting plate body 312 forms the first limiting wall body 112. The second plate body 32 includes a second packaging plate body 321 and a second limiting plate body 322. The second limiting plate body 322 can be folded relative to the second packaging plate body 321. After folding, the second packaging plate body 321 forms the second packaging wall body 121, and the second limiting plate body 322 forms the second limiting wall body 122.

[0058] Among them, Figure 1 As shown, the first limiting plate body 312 and the second limiting plate body 322 are connected as one body, and a third fold 18 is provided between the first limiting plate body 312 and the second limiting plate body 322, that is, the first limiting wall body 112 and the second limiting wall body 122 are connected as one body, and a third fold 18 is provided between the first limiting wall body 112 and the second limiting wall body 122. It can be understood that this can not only further strengthen the structural strength of the retaining rib 30, so that the first limiting wall body 112 and the second limiting wall body 122 are not easily disconnected, but also simplify the packaging process. During packaging, the first limiting plate body 312 and the second limiting plate body 322 are automatically folded under the action of the third fold 18 to form the retaining rib 30, and there is no need to manually connect the first limiting wall body 112 and the second limiting wall body 122, thereby improving the packaging efficiency.

[0059] Further, such as Figure 4As shown, a first fold 16 is provided between one end of the first limiting wall 112 away from the second limiting wall 122 and the first packaging wall 111, and a second fold 17 is provided between one end of the second limiting wall 122 away from the first limiting wall 112 and the second packaging wall 121. It can be understood that by providing the first fold 16 and the second fold 17, when the first plate 31 is folded toward the side where the second plate 32 is located, the first limiting plate 312 and the second limiting plate 322 can be naturally folded into the accommodating space 20 and form the retaining rib 30, that is, the retaining rib 30 can be formed synchronously when the accommodating space 20 is formed, which can simplify the packaging process and improve the packaging efficiency.

[0060] Optionally, in one embodiment, as Figure 1 or Figure 4 As shown, at least one end of the third fold 18 in the length direction is provided with a notch 181, and the notch 181 is recessed relative to the side of the first limiting wall 112 or the second limiting wall 122. This can avoid the first limiting wall 112 and the second limiting wall 122 from being squeezed or wrinkled at the edge of the third fold 18 when folding, so that the folding of the first limiting wall 112 and the second limiting wall 122 is smoother and the appearance of the package 100 can be improved.

[0061] It should be noted that the third fold 18 may be provided with a notch 181 at one end in the length direction, or may be provided with notches 181 at both ends in the length direction. Figure 1 In the structural scheme shown, a notch 181 is provided at one end of the third fold 18 away from the other third fold 18, which can not only reduce the extrusion or wrinkles between the first limiting wall 112 and the second limiting wall 122, but also simplify the production process of the paperboard 300, thereby avoiding excessive production costs.

[0062] Optionally, in one embodiment, as Figure 2 or Figure 3 As shown, a partition plate 40 is further provided in the annular sleeve 10, and the partition plate 40 divides the accommodating space 20 into a plurality of sub-spaces 21, each sub-space 21 being used to install a product 200 to be packaged, so that the partition plate 40 can prevent the products 200 to be packaged in each sub-space 21 from colliding with each other, thereby improving the protective effect on the products 200 to be packaged.

[0063] It should be noted that there may be one or more partition plates 40, one partition plate 40 may divide the receiving space 20 into two sub-spaces 21, and multiple partition plates 40 may divide the receiving space 20 into three or more sub-spaces 21. In short, the number of partition plates 40 and the number of the divided sub-spaces 21 may be designed according to the number of products 200 to be packaged.

[0064] In addition, the partition plate 40 can be connected to any side wall, or can be independent of the annular sleeve body 10, as long as it can stably play a role of partition.

[0065] For example, optionally, in one embodiment, Figure 3 As shown, the plurality of side walls include a first side wall 11, a second side wall 12 and a third side wall 13, the first side wall 11 and the third side wall 13 are respectively connected to the two sides of the second side wall 12, and are respectively folded relative to the second side wall 12 to form an angle; one side of the partition plate 40 is connected to the end of the third side wall 13 away from the second side wall 12, and the other side abuts against the angle between the first side wall 11 and the second side wall 12. That is, in this embodiment, the accommodating space 20 is a square columnar cavity, the partition plate 40 extends between the diagonals of the accommodating space 20, and the partition plate 40 abuts against the angle between the first side wall 11 and the second side wall 12, which can not only improve the stability of the partition plate 40 and prevent the partition plate 40 from slipping or shaking, but also enhance the structural strength of the package 100, thereby improving the protection effect of the packaged product 200.

[0066] Optionally, in one embodiment, as Figure 2 As shown, a first finger hole 41 is further provided on the side of the partition plate 40 away from the third side wall 13. The first finger hole 41 penetrates the partition plate 40 along the thickness direction of the partition plate 40. When the partition plate 40 needs to be folded out of the accommodating space 20, the partition plate 40 can be folded out by holding the first finger hole 41 with a finger, which is very convenient and quick.

[0067] Optionally, in one embodiment, please combine Figure 5 and Figure 6 , the product 200 to be packaged is a support leg for supporting furniture such as beds and sofas, and the product 200 to be packaged includes a bottom plate 201 and a column 202 connected to the bottom plate 201, the subspace 21 is used to accommodate the column 202, and one end of the partition plate 40 in the length direction is spaced from the retaining rib 30 to accommodate the bottom plate 201. That is, in this embodiment, for the product structure including the bottom plate 201 and the column 202, the partition plate 40 can separate the two columns 202 to prevent the two columns 202 from colliding; the partition plate 40 and the retaining rib 30 can jointly limit the movement of the bottom plate 201 in the length direction of the annular sleeve 10, thereby limiting the displacement of the entire product 200 to be packaged.

[0068] Further, such as Figure 6 As shown, the column 202 extends between the bottom plate 201 to which it is connected and the bottom plate 201 of another product 200 to be packaged, and the extension length of the partition plate 40 is greater than the extension length of the column 202. Specifically, in this embodiment, Figure 6As shown, each package 100 is used to package two products 200 to be packaged, and the two openings 15 of the annular sleeve 10 are provided with ribs 30, the partition plate 40 is located between the two ribs 30, and the partition plate 40 is spaced from each rib 30. The bottom plate 201 on one of the products 200 to be packaged is located between the partition plate 40 and one of the ribs 30, and the bottom plate 201 on the other product 200 to be packaged is located between the partition plate 40 and the other rib 30. That is, the columns 202 on each product 200 to be packaged extend between the bottom plate 201 to which it is connected and the bottom plate 201 of the other product 200 to be packaged.

[0069] In order to prevent the column 202 from hitting the bottom plate 201 of another product 200 to be packaged, in the present embodiment, the extension length of the partition plate 40 is greater than the extension length of the column 202. Thus, under the restriction of the partition plate 40, the column 202 cannot hit the bottom plate 201 of another product 200 to be packaged, thereby improving the protective effect on the product 200 to be packaged.

[0070] Optionally, in one embodiment, as Figures 2 to 4 As shown, the multiple side walls include a third side wall 13 and a fourth side wall 14 that are adjacent to each other. A plug hole 131 is provided on a side of the third side wall 13 close to the fourth side wall 14, and a tongue 141 is provided on a side of the fourth side wall 14 close to the third side wall 13. The tongue 141 at least partially passes through the plug hole 131 and extends to a side of the third side wall 13 close to the accommodating space 20 to limit the automatic expansion of the annular sleeve 10.

[0071] Specifically, in this embodiment, the insertion hole 131 can be located at the top of the third side wall 13 and between the third side wall 13 and the partition plate 40, and the insertion hole 131 is connected to the accommodating space 20. At this time, the insertion tongue 141 needs to be inserted into the insertion hole 131 from top to bottom and inserted into the accommodating space 20. At this time, the insertion tongue 141 is completely located on the side of the third side wall 13 close to the accommodating space 20, thereby limiting the automatic expansion of the annular sleeve 10.

[0072] Alternatively, the insertion hole 131 can penetrate the third side wall 13 along the thickness direction of the third side wall 13 and communicate with the accommodating space 20. In this case, the insertion tongue 141 can first move to the side of the third side wall 13 away from the accommodating space 20, and then partially pass through the insertion hole 131 and be inserted into the accommodating space 20. In this case, the insertion tongue 141 is partially located on the side of the third side wall 13 close to the accommodating space 20, which can also limit the automatic expansion of the annular sleeve 10.

[0073] Optionally, in one embodiment, please combine Figure 1 and Figure 4In the length direction of the annular sleeve 10, sharp corner positions 1311 are provided on both sides of the insertion hole 131, and the two sides of the insertion tongue 141 are respectively engaged in the sharp corner positions 1311. It can be understood that by making the two sides of the insertion tongue 141 respectively engaged in the sharp corner positions 1311 of the insertion hole 131, the insertion tongue 141 is not easy to bounce out of the insertion hole 131, thereby improving the insertion stability of the insertion tongue 141 in the insertion hole 131, thereby improving the structural stability of the packaging 100.

[0074] Optionally, in one embodiment, as Figure 2 or Figure 3 As shown, the insertion hole 131 penetrates the third side wall 13 along the thickness direction of the third side wall 13, and in the length direction of the annular sleeve 10, the maximum extension length of the insertion tongue 141 is greater than the opening length of the insertion hole 131. Specifically, in this embodiment, the outer shape of the insertion tongue 141 is a trapezoidal shape. During assembly, the insertion tongue 141 is first turned over to the side of the third side wall 13 away from the accommodation space 20, and then the longer portion of the insertion tongue 141 is inserted into the insertion hole 131 and extends to the side of the third side wall 13 close to the accommodation space 20, thereby limiting the automatic expansion of the annular sleeve 10.

[0075] Of course, in other embodiments, the two sides of the tongue 141 in the length direction may also be arc-shaped, folded line-shaped, etc., as long as the length at a certain position on the tongue 141 is greater than the opening length of the hole 131.

[0076] Optionally, in one embodiment, as Figure 2 or Figure 3 As shown, the insertion hole 131 includes an avoidance hole 1312 and a second finger hole 1313, and the avoidance hole 1312 and the finger hole are both connected to the accommodating space 20. The insertion tongue 141 is inserted into the accommodating space 20 through the avoidance hole 1312, and the second finger hole 1313 is located on the side of the avoidance hole 1312 away from the insertion hole 131. When the annular sleeve 10 needs to be unfolded, a finger can be extended into the accommodating space 20 through the second finger hole 1313 and push the insertion tongue 141 upward, so that the annular sleeve 10 can be unfolded, making the unfolding of the annular sleeve 10 more convenient and quick.
