Description

Technical Field

[0001] This disclosure relates to the field of packaging technology, and more particularly to a paper-plastic packaging component. Background Technology

[0002] Paper-plastic packaging is used for the packaging and protection of various electronic products. Generally, before packing electronic products into boxes, the paper-plastic packaging is first used to partially wrap the sides of the electronic products, and then the paper-plastic packaging and electronic products are stuffed together and fixed in the outer packaging box.

[0003] Traditional paper-plastic packaging, for ease of production and transportation, is typically made into a long strip. When in use, both ends of the strip are bent 90° towards the center along the crease, forming a U-shaped frame for wrapping and securing the sides of electronic products. Traditional paper-plastic packaging features a raised locking platform and a recessed locking groove at the crease. After bending around the crease, the raised platform fits into the recessed groove with an interference fit, securing the long strip. However, this interference fit method results in unstable locking force after bending, leading to detachment and opening. Furthermore, after multiple folds and clamping operations, the interference fit almost completely loses its locking force.

[0004] In view of this, there is an urgent need in the market for a new type of paper-plastic packaging to solve the problems of poor stability when folded and clamped and easy failure after repeated folding and clamping of paper-plastic packaging in related technologies. Utility Model Content

[0005] This disclosure provides a paper-plastic packaging component to address the problems of poor stability during folding and clamping, and easy failure after repeated folding and clamping, in related technologies.

[0006] The paper-plastic packaging component provided in this embodiment includes a main body and a folding part;

[0007] The folded portions are respectively connected to both ends of the main body through fold lines, and can be rotated and bent toward the main body around the fold lines respectively;

[0008] Among them, in the main body and the folding part, one is provided with an insertion boss and the other is provided with an insertion boss;

[0009] The insertion boss is also provided with an insertion port;

[0010] When the folded part rotates and bends toward the main body, the insertion boss can be inserted into the insertion boss at least partially through the insertion port, and is stopped and limited by two parts in different directions.

[0011] In one possible embodiment, the interior of the insertion boss has a receiving cavity that communicates with the insertion port;

[0012] The cavity has a cornered inner wall;

[0013] When the inserting boss is inserted into the receiving boss, the inner wall of the corner cavity can be locked and limited by the limiting top wall of the inserting boss.

[0014] In one embodiment, the limiting top wall includes:

[0015] The first flat wall is connected at one end to the side wall of the insertion boss.

[0016] The first inclined wall is connected to the other end of the first flat wall and extends obliquely downward;

[0017] The second flat wall is connected to the other end of the first inclined wall and is arranged parallel to the first flat wall;

[0018] When the limiting top wall and the corner inner cavity wall are locked and limited, the first inclined wall and the second flat wall can respectively abut against the corner inner cavity wall for limiting.

[0019] In one possible implementation, the limiting top wall further includes a second inclined wall;

[0020] One end of the second inclined wall is connected to the other end of the second flat wall and is arranged parallel to the first inclined wall, while the other end is connected to the other side wall of the insertion boss.

[0021] In one possible embodiment, the insertion port is formed on one side wall of the insertion boss facing the insertion boss;

[0022] The insertion port includes the upper oral cavity wall;

[0023] When the inserting boss is inserted into the receiving boss, the upper oral cavity wall can be perpendicularly blocked and limited by one outer wall of the inserting boss.

[0024] In one possible implementation, the width of the main body portion is equal to the width of the folded portion;

[0025] Furthermore, the main body and the two folded portions extend parallel to each other along the same straight line.

[0026] In one embodiment, the main body is provided with a first clamping groove, and the folding part is provided with a corresponding second clamping groove;

[0027] The first card clamping slot and the second card clamping slot extend in the same direction and are spaced apart.

[0028] In one possible embodiment, clamping protrusions are respectively provided in the sidewalls of the first clamping slot and the second clamping slot;

[0029] The bottom walls of the first and second card clamping slots are respectively provided with supporting protrusions.

[0030] In one possible embodiment, the fold line is perpendicular to the length direction of the main body portion;

[0031] The two folds are foldable around the fold lines respectively, and when the folds are rotated to the position of the main body, the insert boss is positioned at the insertion boss.

[0032] In one embodiment, the main body and the folded portion are integrally formed and connected, and the fold line is an extrusion indentation.

[0033] The technical solution provided in this disclosure has the following advantages compared with related technologies:

[0034] The paper-plastic packaging provided in this embodiment can ensure the relative fixation of the main body and the folded part of the paper-plastic packaging by locking and limiting the two parts of the insertion boss in different directions. Furthermore, the reliability of the locking and limiting mechanism can be fully ensured by strengthening and hardening the local structure of the insertion boss and the insertion boss. Even after multiple folds, the locking and limiting mechanism between the insertion boss and the insertion boss will have little impact on the stability of the locking and limiting mechanism, and the insertion boss and the insertion boss will still have a good locking and limiting effect.

[0045] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0046] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0047] Combination Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the present disclosure provides a paper-plastic packaging component, which includes a main body 1 and a folding part 2. The folding part 2 is respectively connected to both ends of the main body 1 through fold lines 3, and can be rotated and bent toward the main body 1 around the fold lines 3. In the main body 1 and the folding part 2, one is provided with an insertion boss 21, and the other is provided with an insertion boss 11. The insertion boss 11 also has an insertion opening 111. When the folding part 2 is rotated and bent toward the main body 1, the insertion boss 21 can be at least partially inserted into the insertion boss 11 through the insertion opening 111, and is blocked and limited by two parts in different directions.

[0048] The paper-plastic packaging provided in this embodiment can be used, but is not limited to, for packaging various electronic devices, precision instruments, and fragile items. In specific use, the two folded portions 2 at both ends of the main body 1 are first rotated around the fold line 3 toward the main body 1 by a certain angle (e.g., 60°, 90°, or 120°, which can be adapted to the corner angle of the item to be packaged). The insertion boss 21 in the folded portion 2 is inserted into the insertion port 111 of the insertion boss 11 in the main body 1. At this time, the insertion boss 11 can be locked and limited by at least two parts in different directions, thereby fixing the main body 1 and the folded portion 2 relative to each other.

[0049] The paper-plastic packaging provided in this embodiment can be locked and limited by two different directional parts inside the insertion boss 11. This locking and limiting mechanism ensures the relative fixation of the main body 1 and the folded part 2 within the paper-plastic packaging. Furthermore, the reliability of the locking and limiting mechanism can be further ensured by strengthening and hardening the local structures of the insertion boss 11 and the insertion boss 21. Moreover, even after multiple folds, although friction and wear occur between the insertion boss 11 and the insertion boss 21, the stability of the locking and limiting mechanism is minimal, and the insertion boss 11 and the insertion boss 21 still maintain a good locking and limiting effect.

[0050] In summary, the paper-plastic packaging provided in this embodiment achieves relative fixation of the folded part 2 by the locking and limiting cooperation between the insertion boss 11 and the insertion boss 21. It has good locking and fixing stability and still has a good locking and limiting effect after multiple folding and opening. It solves the problems of poor fixing stability and easy failure of interference fitting after repeated opening, folding and friction wear in the paper-plastic packaging using interference fitting method in related technologies.

[0051] In one embodiment, the interior of the insertion boss 11 has a receiving cavity 112 that communicates with the insertion port 111; the receiving cavity 112 has a corner inner wall 112a; when the insertion boss 21 is inserted into the insertion boss 11, the corner inner wall 112a can be locked and limited by the limiting top wall 211 of the insertion boss 21.

[0052] Specifically, in combination Figure 4In further detail, a receiving cavity 112 communicating with the receiving port 111 is provided inside the receiving boss 11. The cross-sectional area of ​​the receiving cavity 112 can be set to be larger than the opening area of ​​the receiving port 111, forming a structure with a small opening and a large inner cavity. Moreover, the receiving cavity 112 has a corner inner cavity wall 112a. When the inserting boss 21 is inserted into the receiving boss 11, the inserting boss 21 can at least partially extend into the receiving cavity 112. After being inserted into place, the corner inner cavity wall 112a can lock against the limiting top wall 211 of the inserting boss 21, so that the two can remain relatively fixed. This allows the inserting boss 21 to be locked and limited inside the receiving boss 11, thereby achieving relative fixation between the main body 1 and the folding part 2.

[0053] The specific arrangement of the above-mentioned accommodating cavity 112 and the corner inner cavity wall 112a has the beneficial effect of simple structure and can firmly block and limit the limiting top wall 211 of the insertion boss 21.

[0054] In one embodiment, the limiting top wall 211 includes a first flat wall 211a, a first inclined wall 211b, and a second flat wall 211c; one end of the first flat wall 211a is connected to the side wall of the insertion boss 21, the first inclined wall 211b is connected to the other end of the first flat wall 211a, and extends obliquely downward; the second flat wall 211c is connected to the other end of the first inclined wall 211b, and is arranged parallel to the first flat wall 211a; wherein, when the limiting top wall 211 is engaged and limited by the corner inner cavity wall 112a, the first inclined wall 211b and the second flat wall 211c can respectively abut against and limit the corner inner cavity wall 112a.

[0055] Specifically, in combination Figure 2 In further detail, the limiting top wall 211 is specifically configured to include a first flat wall 211a, a first inclined wall 211b, and a second flat wall 211c connected in sequence, with the first inclined wall 211b extending obliquely downwards. In this way, the insert boss 21 can correspondingly form a "stepped" limiting top wall 211 with a gradual height difference.

[0056] In addition, when the insertion boss 21 rotates and is inserted into the receiving cavity 112 of the insertion boss 11, the limiting top wall 211 and the corner inner cavity wall 112a form a blocking limit, and respectively abut against the corner inner cavity wall 112a through the first inclined wall 211b and the second flat wall 211c, so that the insertion boss 21 can be stably blocked and limited in the receiving boss 11.

[0057] The specific arrangement of the aforementioned limiting top wall 211 has the advantages of simple structure and can ensure stable blocking and limiting of the insertion boss 21 and the insertion boss 11.

[0058] In one embodiment, the limiting top wall 211 further includes a second inclined wall 211d; one end of the second inclined wall 211d is connected to the other end of the second flat wall 211c and is arranged parallel to the first inclined wall 211b, and the other end is connected to the other side wall of the insertion boss 21.

[0059] Specifically, in combination Figure 2 In further detail, a second inclined wall 211d is also provided in the limiting top wall 211, with the other end of the second flat wall 211c connected to it. The second flat wall 211c is configured to be parallel to the first inclined wall 211b and inclined downwards, and is connected to the other side wall of the insertion boss 21. This allows the limiting top wall 211 of the insertion boss 21 to form a "notched corner". When the insertion boss 21 rotates and is inserted into the receiving cavity 112 of the insertion boss 11, the second inclined wall 211d can better avoid the insertion port 111 of the insertion boss 11, so that the insertion boss 21 can be inserted and limited in the receiving cavity 112 of the insertion boss 11 more smoothly and effortlessly.

[0060] In one embodiment, the insertion port 111 is formed on one side wall of the insertion boss 11 facing the insertion boss 21; the insertion port 111 includes an upper oral cavity wall 111a; when the insertion boss 21 is inserted into the insertion boss 11, the upper oral cavity wall 111a can be perpendicularly blocked and limited by an outer side wall of the insertion boss 21.

[0061] Specifically, in combination Figure 2 and Figure 4 In further detail, the insertion port 111 is specifically opened on one side wall of the insertion boss 11 facing the insertion boss 21, and the insertion port 111 has an upper oral cavity wall 111a. When the insertion boss 21 is inserted into the insertion boss 11, the upper oral cavity wall 111a can be vertically blocked and limited by one outer side wall of the insertion boss 21, further improving the blocking and limiting effect of the insertion boss 21 and the insertion boss 11 after insertion.

[0062] Of course, the insertion boss 21 can also be provided with a locking and limiting mechanism in the outer side wall, such as a locking groove or locking edge, for the upper oral cavity wall 111a to perform insertion locking or clamping locking, further improving the locking and limiting effect of the upper oral cavity wall 111a on the insertion boss 21.

[0063] In one embodiment, the main body 1 and the folding part 2 have the same width; and the main body 1 and the two folding parts 2 extend parallel to each other along the same straight line direction.

[0064] Specifically, in combination Figure 1To elaborate further, the main body 1 and the folding part 2 of the paper-plastic packaging are set to the same width, and the main body 1 and the folding parts 2 at both ends of the main body 1 extend in the same straight line direction. When the two folding parts 2 are rotated, bent and inserted towards the main body 1, they can form a U-shaped structure of equal thickness together with the main body 1, so that the three sides of the package can be wrapped and packaged. Then, it can be stuffed into the packaging box or packaging shell along with the package.

[0065] The specific arrangement of the main body 1 and the folding part 2 has the advantages of simple structure and convenient packaging with the items to be packaged.

[0066] In one embodiment, the main body 1 is provided with a first clamping groove, and the folding part 2 is provided with a corresponding second clamping groove; the first clamping groove and the second clamping groove extend in the same direction and are spaced apart.

[0067] Specifically, in combination Figure 1 In further detail, a first clamping groove is provided in the main body 1, which extends along the length of the main body 1 and is located at the center of the main body 1; a second clamping groove is provided in the folding part 2, which extends along the length of the folding part 2 and is located at the center of the folding part 2. Thus, the first clamping groove and the second clamping groove can extend in the same direction and be spaced apart. Moreover, when the folding part 2 is rotated and folded toward the main body 1, the first clamping groove and the second clamping groove can be connected to each other, so as to be used to clamp and wrap the packaged item together in the same thickness direction.

[0068] In one embodiment, clamping protrusions are respectively provided in the side walls of the first clamping groove and the second clamping groove; and supporting protrusions are respectively provided in the bottom walls of the first clamping groove and the second clamping groove.

[0069] Specifically, in combination Figure 1 To elaborate further, clamping protrusions are provided on the side walls of the first and second clamping slots, respectively. The clamping protrusions can be specifically designed as semi-hollow structures with a certain elastic deformation function. In this way, when the packaged item is inserted into the first and second clamping slots, the clamping protrusions can press against the upper and lower sides of the packaged item along the thickness direction, thereby improving the clamping and positioning stability of the packaged item.

[0070] Furthermore, support protrusions are provided in the bottom walls of the first and second card clamping slots, respectively. The support protrusions can also be specifically designed as semi-hollow structures with a certain elastic deformation function. In this way, when the packaged item is inserted into the first and second card clamping slots, the support protrusions can support and abut against the side wall of the packaged item, further improving the clamping and positioning stability of the packaged item.

[0071] In one embodiment, the fold line 3 is perpendicular to the length direction of the main body 1; the two folding parts 2 can be rotated and folded around the fold line 3 respectively, and when the folding part 2 rotates to the position where the main body 1 is perpendicular, the insertion boss 21 is correspondingly positioned at the insertion boss 11.

[0072] Specifically, in combination Figure 1 In further detail, the fold line 3 is set perpendicular to the length direction of the main body 1. This way, when the two folding parts 2 can rotate and fold around the fold line 3 respectively, the two folding parts 2 can always be kept in the same thickness layer as the main body 1, thereby ensuring that the folding parts 2 and the main body 1 can jointly package the item to be packaged in the same thickness layer.

[0073] In one embodiment, the main body 1 and the folded part 2 are integrally formed and connected, and the fold line 3 is an extrusion indentation.

[0074] The paper-plastic packaging can be integrally molded from paper or plastic materials through high-temperature pressing, so that the main body 1 and the folded part 2 can be integrally connected, and the fold 3 can be squeezed by the protruding extrusion strip in the molding die to form an extrusion indentation in the paper-plastic packaging.

[0075] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0076] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
