Description

Technical Field

[0001] The present invention belongs to the field of packaging, and particularly relates to a packaging liner for separating and fixing the occlusion disc and the anchoring frame of an occluder. Background Art

[0002] At present, many products in the field of medical devices are generally dumbbell-shaped as a whole, with upper and lower parts in structure, and the upper and lower parts are connected by a "waist" formed by a connecting member with a relatively small size. For example, almost all products such as the vast majority of left atrial appendage occluders, atrial septal defect creation stents, ventricular septal defect occluders, and atrial septal defect occluders are "I"-shaped structures containing upper and lower parts.

[0003] Taking the commonly used "disc-cover type" left atrial appendage occluder as an example, it includes two components, an anchoring frame and an occlusion disc. The anchoring frame usually has tip barbs for anchoring the left atrial appendage. If the product is improperly packaged and squeezed, the barbs on the anchoring frame can easily pierce the flow-blocking film on the occlusion disc, resulting in product defects. At the same time, there is also a risk that the product cannot return to its original shape or even break after being squeezed and deformed for a long time, causing potential safety hazards to the product. These problems are fatal dangers for the occluder. Once a defective occluder is implanted into a patient's body, it will cause irreparable harm to the patient's life and health. The existing packaging designs on the market are relatively complex, with limited protection scope, and are not easy for users to operate, making it difficult to solve the problems faced by the product in the existing packaging methods. For example, Patent CN209650816U relates to a packaging partition, which has the following problems in actual use:

[0004] Before assembly: a) The shapes of the two card slot tabs on the upper partition are T-shaped, and the shapes of the two card slot receiving openings on the lower partition are double-L-shaped. The widths of the two card slot tabs on the upper partition are greater than the widths of the two double-L-shaped card slot receiving openings on the lower partition. The card slot tabs on the upper partition need to be forcibly bent before they can be placed into the card slot receiving openings on the lower partition. The bent card slot tabs will form sharp corners, damaging the object to be packaged; b) The two card slot tabs on the upper partition and the two double-L-shaped ones on the lower partition are a rotating structure (need to rotate 90°), resulting in a certain distance being required between the object to be packaged and the rotating structure to ensure that the object to be packaged is not affected, thus increasing the design space of the lower partition and increasing the cost; c) The bending structure of the lower partition is only formed by bending a flat sheet, with insufficient strength. After bending and remaining stationary for a long time, there will be a certain recovery effect, causing the protection cavity formed by the bending structure to deform and unable to effectively protect the object to be packaged. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and provide a packaging liner that can effectively separate and protect the upper and lower parts of the object to be packaged, with a simple structure and convenient disassembly and assembly.

[0010] Preferably, when the number of the hole grooves is multiple and the fitting portion of the limiting draw bar is a flat sheet structure, a limiting protrusion is provided at one end of the fitting portion to realize the single-direction movement of the limiting draw bar relative to the bearing plate. An outward convex structure is provided at the other end of the fitting portion, and the outward convex structure and the hole groove on the bearing plate adopt interference fit or transition fit to prevent the limiting draw bar and the bearing plate from sliding or shaking in the natural state;

[0011] When the number of the hole grooves is only one and the fitting portion of the limiting draw bar is a flat sheet structure or a three-dimensional structure, the fitting portion of the limiting draw bar is provided with a quick insertion structure, and the quick insertion structure causes the fitting portion to undergo elastic deformation, so as to facilitate the realization of the portable assembly of the limiting insert bar inserted into the bearing plate while increasing the release force between the fitting portion and the hole groove.

The card slot is a semi-through structure and constitutes the mutually cooperating groove structure, so that the limiting draw box can be separated and disassembled from the carrier plate by horizontal movement.

[0015] Preferably, at least two bending structures are provided at the edge position of the carrier plate, and the bending structures form the protection cavity after being bent and deformed.

[0016] Preferably, a reinforcement structure is provided at the bending structure on the carrier plate and / or the limiting member for enhancing the spatial stability of the protection cavity formed by the bending structure.

[0018] Compared with the prior art, this patent has the following prominent advantages:

[0019] 1. A packaging liner provided by the present invention is provided with a limiting member. The limiting member includes a fitting portion and a holding portion. The fitting portion is in mutual contact with the bearing plate to play a limiting role. The holding portion is free outside the bearing plate, facilitating the quick removal of the limiting member and not contacting the object to be packaged, ensuring the safety and effectiveness of the packaged object. The limiting member has various forms, which can be a limiting draw bar, a limiting flat plate or a limiting draw box. The design of the limiting draw bar has the following advantages: a) The fitting portion of the limiting draw bar and the bearing plate are in an interpenetrating structure. During the removal process, the holding portion of the limiting draw bar can only be pulled out unidirectionally, limiting the way of removing the package and ensuring that the packaged item is not damaged when the product is removed; b) The force applied to the holding portion of the limiting draw bar is gentle during the removal process, and it will not cause damage to the packaging material and the object to be packaged; c) The way adopted by the holding portion of the limiting draw bar during the removal process is a single-direction sliding removal. The reserved length of the limiting draw bar conforms to ergonomics during the removal of the holding portion, facilitating the operator to hold by hand, and the removal method is simple; d) After the limiting draw bar is removed, it is completely separated from the bearing plate and will not cause secondary damage to the product; The design of the limiting flat plate has the following advantages: a) The groove structure design makes the removal action stroke of the operator for the limiting flat plate short, and the operation is more smooth and simple; b) The design is simple and has high recognition; The design of the limiting draw box has the following advantages: The formed protection cavity is used to provide more comprehensive protection for the object to be packaged, preventing the object to be packaged from being damaged during transportation and use.

[0020] 2. A packaging liner provided by the present invention is provided with a bearing plate, which has the following advantages: a) It can effectively separate the objects to be packaged, avoiding mutual contamination, abrasion and damage of the objects to be packaged; b) There is no redundant structure at the position and surrounding area of the contact surface between the bearing plate and the object to be packaged, and the design is simple and clear, ensuring that the object to be packaged is not affected during the removal process; c) In one embodiment, a height support structure is provided at the end of the placement groove, which can protect the waist of a specific object to be packaged and effectively avoid vertical shaking of the object to be packaged, especially suitable for some objects to be packaged with a relatively high waist height; d) In one embodiment, a double-layer bearing plate is provided, which can further enhance the overall strength of the liner, increase the bearing capacity of the liner, and form multiple protections for the object to be packaged.

[0021] 3. The bending structure of the packaging liner provided by the present invention is provided with a reinforcement structure, which has the following advantages: a) It can effectively protect the protection cavities of the carrier plate and / or the limiting members, ensuring that the protection cavities have sufficient strength to support and resist external forces, and ensuring that the reinforcement auxiliary structure can protect the object to be packaged from being deformed, worn, and damaged due to the extrusion of the protection cavity by external forces; b) The reinforcement structures are diverse, including reinforcing ribs, adhesive reinforcing members, snap - type reinforcing members, draw - bar - type reinforcing members, and their combinations, which can adapt to different product requirements. The main feature of the reinforcing ribs is that this structure occupies little space and can maintain the structure of the protection cavity without changing the overall shape. At the same time, the position where it is set avoids the object to be packaged, and has little impact on the limiting members, the carrier plate, and the object to be packaged during the disassembly and assembly process; The main feature of the adhesive reinforcing member is that it realizes the fixation and limitation between adjacent two bending structures through adhesion, enhancing the overall strength of the bending structure. Its characteristics are simple design and short production process flow; The snap - type reinforcing member is one or more snap structures formed at adjacent two bending structures, or one or more snap structures formed between the bending structure and the carrier plate. The main feature is that the snap structure can limit the movement of the bending structure, thereby enhancing the maximum bearing capacity at the bending structure. At the same time, the snap structure adopts a transition fit, and its mating state effectively prevents the risk of the snap - type reinforcing member falling off, increasing the safety and reliability of the snap - type reinforcing member, and can change the position of the snap according to the shape of the object to be packaged, which can enhance the support and protection effect to a greater extent; The draw - bar - type reinforcing member is a draw - bar structure formed at adjacent two bending structures. Through the interpenetration design of the draw - bar structure, the bearing capacity of adjacent two bending structures is improved. Its characteristic is that it can be fixed without adding additional materials, and the production process is short; c) The reinforcement structure can form various combined structures according to actual usage requirements, further improving the reinforcement function and enhancing the protection for the object to be packaged.

[0022] 4. For a packaging liner provided by the present invention, the limiting member and the carrier plate achieve the functions of assembly and disassembly through a groove structure. This design has the following advantages: a) It uses the structures of the limiting member and the carrier plate itself for mechanical cooperation to achieve the assembly and disassembly of the two, without the need to add additional accessories, with a simple structure, a short production process flow for the liner, energy - saving and environmental - friendly, and convenient for the operator to use; b) The groove structure design is diverse and can be designed specifically according to different requirements to meet the

[0023] personalized customization needs. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiment

[0053] The packaging partition of the present invention can effectively and three-dimensionally divide the upper and lower parts of the item to be packaged and protect the surfaces of the upper and lower parts; the practical method is simple and clear, the structure is simple, the disassembly and assembly are convenient, and the item to be packaged will not be damaged secondarily after disassembly and assembly.

[0054] Such as ​As shown in the figure, the present invention provides a packaging liner 1, which includes a bearing plate 10 and a limiting member 11. A storage groove 100 is provided on the bearing plate 10, and at least a part of the to-be-packaged object 2 is placed in the storage groove 100. The limiting member 11 includes a fitting portion 113 and a holding portion 114. At least a part of the fitting portion 113 is in mutual contact with the bearing plate 10, and the holding portion 114 can be separated from the bearing plate 10. The bearing plate 10 is provided with a groove structure 12 that cooperates with the fitting portion 113, and the assembly and disassembly functions of the two are achieved through horizontal sliding. Relative to the bearing plate 10, the sliding direction of the limiting member 11 is not parallel to the initial direction of taking out the to-be-packaged object 2. The included angle between the defined sliding direction and the initial direction of taking out is defined as θ, and θ satisfies the following mathematical formula: 0° < θ ≤ 90°; the to-be-packaged object 2 can be limited within the space defined by the storage groove 100 and the limiting member 11.

[0055] In the present invention, the limiting member 11 and the bearing plate 10 achieve the assembly and disassembly functions through the groove structure 12. Among them,

[0056] The bearing plate 10 is designed with the following advantages: a) It can effectively separate the to-be-packaged objects 2, avoiding mutual contamination, abrasion and product damage between the to-be-packaged objects 2; b) There is no redundant structure at the position and the surrounding area of the contact surface with the to-be-packaged object 2 on the bearing plate 10, and the design is simple and clear, ensuring that the to-be-packaged object 2 is not affected during the taking-out process.

[0057] The design of the groove structure 12 has the following advantages: a) The assembly and disassembly of the two are realized through the mechanical cooperation of the structures of the limiting member 11 and the bearing plate 10 itself, without the need to add additional accessories. The structure is simple, the production process flow of the packaging liner 1 is short, energy-saving and environmentally friendly, and it is convenient for the operator to use; b) The design of the groove structure 12 is diverse, and targeted structural design can be carried out according to different requirements to meet the personalized customization needs of customers.

[0058] In a preferred embodiment, the shape of the bearing plate 10 is one or more combinations of polygons, circles, semi-circles, and ellipses.

[0059] In an embodiment, the above-mentioned limiting member 11 is a limiting draw bar 110. At least one hole groove 101 is provided on the bearing plate 10. The fitting portion 113 of the limiting draw bar 110 can be inserted into the hole groove 101, and the hole groove 101 and the fitting portion 113 form a mutually cooperating groove structure 12, as ​ shown. Preferably, the cooperation between the fitting portion 113 and the hole groove 101 is one or more combinations of transition fit, interference fit, and clearance fit. In a preferred embodiment, the shape of the hole groove 101 is one or more combinations of rectangles, circles, keyways, and ellipses, as ​ a~ ​ d shown.

[0060] The design of the limiting draw bar 110 has the following advantages: a) The fitting part 113 of the limiting draw bar 110 and the carrier plate 10 are in an interpenetrating structure. During the removal process, the limiting draw bar 110 can only be pulled out unidirectionally, which limits the way of removing the package and ensures that the packaged items are not damaged when the product is removed; b) The holding part 114 of the limiting draw bar 110 has a gentle force during the removal process and will not damage the packaging material and the items to be packaged; c) The holding part 114 of the limiting draw bar 110 adopts a single-direction sliding removal method during the removal process. The reserved length of the holding part 114 of the limiting draw bar 110 during the removal process conforms to ergonomics, which is convenient for the operator to hold by hand, and the removal method is simple; d) After the holding part 114 of the limiting draw bar 110 is removed, it is completely separated from the carrier plate 10 and will not cause secondary damage to the product.

[0061] In one embodiment, when the number of the holes 101 on the carrier plate 10 is multiple, the fitting part 113 of the limiting draw bar 110 is a flat plate structure. When the number of the holes 101 on the carrier plate 10 is only one, the fitting part 113 of the limiting draw bar 110 is a flat plate structure or a three-dimensional structure. The three-dimensional structure forms a protection cavity 130 for accommodating and protecting part of the items to be packaged 2.

[0062] In a preferred embodiment, the number of the holes 101 on the carrier plate 10 is multiple, and the fitting part 113 of the limiting draw bar 110 is a flat plate structure. At this time, a limiting protrusion 1101 is provided at one end of the fitting part 113 to realize the single-direction movement of the limiting draw bar 110 relative to the carrier plate 10, which is convenient for the operator to intuitively judge the extraction direction of the limiting draw bar 110. An outward convex structure 1100 is provided at the other end of the fitting part 113. The outward convex structure 1100 and the holes 101 on the carrier plate 10 adopt interference fit or transition fit to prevent the limiting draw bar 110 and the carrier plate 10 from sliding or shaking in the natural state, and can effectively protect the items to be packaged 2. As ​ and 4b shown, at this time, the horizontal distance between the limiting protrusion 1101 and the outward convex structure 1100 is defined as L1, and the maximum horizontal distance between two holes 101 on the carrier plate 10 is defined as L2. Then, L1 and L2 satisfy the following mathematical relationship: L1 = L2. As ​ and 4b shown.

[0063] The advantage of this design is that it can prevent the limiting draw bar 110 from moving or shaking on the carrier plate 10 to the greatest extent and protect the items to be packaged 2. In a preferred embodiment, the outward convex structure 1100 and the limiting protrusion 1101 have a flat plate structure. The shape of the limiting protrusion 1101 is one or a combination of more than one of semi-circular, triangular, polygonal, wavy or irregular shapes. As ​ shown.

[0064] In another preferred embodiment, after the fitting portion 113 of the carrier plate 10 and the limiting draw bar 110 are fitted, the maximum peripheral area of the limiting draw bar 110 with the outer convex structure 1100 at one end does not exceed the maximum peripheral area of the carrier plate 10, preventing the operator from misoperation and improving the applicability and aesthetics, as ​ shown.

[0065] In another preferred embodiment, an open hole 1103 is provided at the limiting draw bar 110 on the side where the outer convex structure 1100 is provided. The design of the open hole 1103 is beneficial to the quick removal of the limiting draw bar 110 after the insertion and fitting. The specific manifestation is that when the limiting draw bar 110 is removed, the outer convex structure 1100 of the limiting draw bar 110 can achieve a large deformation due to the design of the open hole 1103, facilitating the smooth and stable removal of the limiting draw bar 110 from the card slot 102, as ​ shown; preferably, the shape of the open hole 1103 is one or more combinations of square, circular, T-shaped, I-shaped, and slit-shaped, as ​ a~ ​ e shown.

[0066] In a preferred embodiment, the shape of the limiting protrusion 1101 is one or more combinations of semi-circular, triangular, polygonal, wavy, or irregular.

[0067] In another embodiment, the number of the hole grooves 101 on the carrier plate 10 is only one, and the fitting portion 113 of the limiting draw bar 110 is a flat plate structure or a three-dimensional structure. At this time, a quick insertion structure 1102 is provided on the fitting portion 113 of the limiting draw bar 110. The quick insertion structure 1102 causes the fitting portion 113 to undergo elastic deformation, so as to facilitate the portable assembly of the limiting draw bar 110 inserted into the carrier plate 10 while increasing the release force between the fitting portion 113 and the hole groove 101; one end of the fitting portion 113 of the limiting draw bar 110 is provided with an outer convex structure 1100 for preventing the limiting draw bar 110 from sliding or shaking with the carrier plate 10 in the natural state. At this time, the maximum horizontal distance between the outer convex structure 1100 and the proximal end of the quick insertion structure 1102 is defined as L3, and the maximum horizontal distance between the hole groove 101 and the storage groove 100 is defined as L4. Then, L3 and L4 satisfy the following mathematical relationship: L3 = L4, as ​ and 9b shown.

[0068] The advantage of this design is that the quick insertion structure 1102 and the limited space of the storage groove 100 further limit the to-be-packaged object 2, preventing the to-be-packaged object 2 from moving or shaking. In a preferred embodiment, the shape of the quick insertion structure 1102 is one or more combinations of rectangular, keyway-shaped, circular, oval, and conical, as ​a to ​ as shown in e.

[0069] In another embodiment, as shown in FIGS. 1 and ​ shown, at least two bending structures 13 are provided at the edge position of the carrier plate 10. After bending deformation, the bending structures 13 form a protection cavity 130. The protection cavity 130 is used to accommodate and protect part of the to-be-packed object 2. At the same time, the bending structures 13 can support the carrier plate 10, fully protecting the to-be-packed object 2. In a preferred embodiment, a bending structure 13 is provided on each of the two sides and the opposite side of the edge position where the object placing groove 100 of the carrier plate 10 is located, as ​ and ​ shown. After bending deformation, the bending structure 13 forms a protection cavity 130 for accommodating and protecting part of the to-be-packed object 2.

[0070] In one embodiment, as ​ and ​ shown, an indication mark 14 is provided on the holding part 114 of the carrier plate 10 and / or the limiting member 11, which is convenient for identifying the disassembly method of the limiting member 11 and the carrier plate 10.

The colors and fillers can achieve the function of quickly identifying the disassembly method of the packaging liner 1 by different color differentiations and local addition of fillers.

[0071] Specifically, the object of the present invention can also be further realized by the following technical solutions:

[0072] In one embodiment, a reinforcement structure 1300 is provided at the bending structure 13 on the carrier plate 10 and / or the limiting member 11, which is used to enhance the spatial stability of the protection cavity 130 formed by the bending structure 13. The specific structure of the reinforcement structure 1300 is as follows:

[0073] (1) ​ and ​ are schematic diagrams of the reinforcing rib 13001. The reinforcing rib 13001 is provided on the bending structure 13 of the protection cavity 130. The advantage of this design is that it can maintain the structure of the protection cavity 130 without changing the overall shape, and at the same time, the position where it is provided avoids the to-be-packed object 2, and has little influence on the limiting member 11, the carrier plate 10, and the to-be-packed object 2 during the disassembly and assembly process;

[0074] (2) ​ and ​ is a schematic diagram of an adhesive type reinforcement member, which realizes fixation and limit at the extension part between two adjacent bending structures 13 through adhesion, enhances the overall strength of the bending structure 13, and is characterized by simple design and short production process flow;

[0075] (3) The snap - type reinforcement member 13002 is one or more snap structures formed at two adjacent bending structures 13, or one or more snap structures formed between the bending structure 13 and the carrier plate 10, as shown in ​ 、 ​ and ​ 、 ​ respectively. The main feature is that the snap structure can limit the movement of the bending structure 13, thereby enhancing the maximum bearing capacity at the bending structure 13. At the same time, the snap structure adopts a transition fit, and its fit state effectively prevents the risk of the snap - type reinforcement member 13002 falling off, increases the safety and reliability of the snap - type reinforcement member 13002, and can change the position of the snap according to the shape of the packaged item 2, which can enhance the support and protection effect to a greater extent;

[0076] (4) ​ and ​ is a schematic diagram of a draw - bar type reinforcement member 13004. The draw - bar type reinforcement member 13004 is a draw - bar structure formed at two adjacent bending structures 13. Through the interpenetration design of the draw - bar structure, the bearing capacity of two adjacent bending structures 13 is improved, and its feature is that it can be fixed without adding extra materials and the production process is short.

[0077] In addition, in one embodiment, the reinforcement structure 1300 can form a combination structure in various forms according to actual usage requirements, further improving the reinforcement function and enhancing the protection of the packaged item 2. In a preferred embodiment, the reinforcement structure 1300 is a combination of one or more of the reinforcing rib 13001, the snap - type reinforcement member 13002, the adhesive - type reinforcement member 13003, and the draw - bar type reinforcement member 13004, further strengthening the stability and bearing capacity of the protection cavity 130.

[0078] In one embodiment, as shown in ​ , the limiting member 11 is a limiting flat plate 111, and at least one folding structure 1110 is provided on the limiting flat plate 111. At least one hole groove 101 is provided on the carrier plate 10, and the hole groove 101 corresponds to the folding structure 1110 in terms of quantity and position. The folding structure 1110 and the hole groove 101 form a mutually cooperating groove structure 12.

[0079] The design of the limiting flat plate 111 has the following advantages: a) The groove structure 12 is designed such that the operator has a short stroke for disassembling the limiting flat plate 111, and the operation is smoother and simpler; b) The design is simple and highly recognizable.

[0080] In a preferred embodiment, as ​ a to ​ e shown, the shape of the flap structure 1110 is one or a combination of a circle, a rhombus, a square, an ellipse, and a semi - circle.

[0081] In a preferred embodiment, as ​ shown, the fitting portion 113 of the limiting flat plate 111 is provided with a quick - insertion structure 1102, and the to - be - packaged object 2 is limited within the limited space formed by the quick - insertion structure 1102 and the placement groove 100.

[0082] In another preferred embodiment, the flap structure 1110 is provided with an outward - convex structure 1100, and the outward - convex structure 1100 and the hole groove 101 are in interference fit or transition fit, which is used to prevent the limiting flat plate 111 from sliding or shaking with the carrier plate 10 in the natural state, and can effectively protect the to - be - packaged object 2.

[0083] More preferably, an opening - type hole 1103 is provided at the flap structure 1110, and the shape of the opening - type hole 1103 is one or a combination of a square, a circle, a T - shape, an I - shape, and a slit - shape. As ​ a to ​ d shown, the design of the opening - type hole 1103 is beneficial for quickly removing the flap structure 1110 of the limiting flat plate 111 from the hole groove 101 of the carrier plate 10. Specifically, when removing the limiting flat plate 11, due to the design of the opening - type hole 1103, the outward - convex structure 1100 of the flap structure 1110 can achieve a large deformation, which is convenient for the limiting draw bar 110 to be smoothly removed from the card slot 102.

[0084] In another embodiment, the fitting portion 113 of the limiting flat plate 111 may be provided with a three - dimensional protective cavity 130 for protecting part of the to - be - packaged object 2. As ​ and ​ shown, the protective cavity 130 is fixed to the limiting flat plate 111 through mechanical fitting and / or gluing.

[0085] In a preferred embodiment, a height support structure 103 is provided at the end of the storage groove 100. The height support structure 103 has a three-dimensional structure and can protect the waist of a specific package-to-be 2 to prevent it from vibrating vertically. For example, for some left atrial appendage occluders with a large distance between the occlusion disc and the anchoring frame, their waists are often long. The height support structure 103 can effectively protect the waist of the left atrial appendage occluder and prevent its waist from having a large degree of freedom of movement in the packaging liner 1 and vibrating vertically, thereby avoiding secondary damage to the product during transportation, such as ​ as shown

[0086] In an embodiment, as ​ shown, the limiting member is a limiting drawer 112. The fitting portion 113 of the limiting drawer 112 has a three-dimensional structure and forms at least one protection cavity 130. The protection cavity 130 is used to accommodate and protect a part of the package-to-be 2. At least one card slot 102 is provided on both the bearing plate 10 and the fitting portion 113 of the limiting drawer 112. The card slots 102 on the fitting portion 113 and the card slots 102 on the bearing plate 10 correspond to each other in number and position. The card slot 102 is a semi-through structure and constitutes a mutually cooperating groove structure 12, so that the limiting drawer 112 can be separated and disassembled from the bearing plate 10 by horizontal movement.

[0087] In a preferred embodiment, the shape of the card slot 102 is one or more combinations of slit-shaped, square, circular, and oval.

[0088] To make the purpose, technical solution and advantages of the present invention clearer, the following further elaborates on the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not used to limit the present invention.

[0089] Example 1:

[0090] ​ The following shows a schematic diagram of a packaging liner 1 in this embodiment, including a bearing plate 10 and a limiting member 11. A storage groove 100 is provided on the bearing plate 10. At least a part of the package-to-be 2 is placed in the storage groove 100. The limiting member 11 includes a fitting portion 113 and a holding portion 114. At least a part of the fitting portion 113 is mutually fitted with the bearing plate 10. The holding portion 114 can be outside the bearing plate 10. The bearing plate 10 is provided with a groove structure 12 that cooperates with the fitting portion 113, and the assembly and disassembly functions of the two are realized by horizontal sliding. Relative to the bearing plate 10, the sliding direction of the limiting member 11 is non-parallel to the initial direction of taking out the package-to-be 2. Define the angle between the sliding direction and the initial direction of taking out as θ, and θ satisfies the following mathematical formula 0° < θ ≤ 90°; the package-to-be 2 can be limited within the space defined by the storage groove 100 and the limiting member 11, as ​ and​ As shown

[0091] In this embodiment, the above-mentioned limiting member 11 is a limiting draw bar 110. The fitting portion 113 of the limiting draw bar 110 is a flat sheet structure. At least one hole groove 101 is provided on the carrier plate 10. The fitting portion 113 of the limiting draw bar 110 can be inserted into the hole groove 101, and the hole groove 101 and the fitting portion 113 form a mutually matching groove structure 12, as ​ shown

[0092] Embodiment Two:

[0093] As ​ and 4b shown, this embodiment is based on Embodiment One. The difference between this embodiment and Embodiment One is that: a limiting protrusion 1101 is provided at one end of the fitting portion 113 of the limiting draw bar 110, which is used to realize the single-direction movement of the holding portion 114 of the limiting draw bar 110 relative to the carrier plate 10, facilitating the operator to intuitively judge the extraction direction of the limiting draw bar 110. An outward convex structure 1100 is provided at the other end of the fitting portion 113. The outward convex structure 1100 and the hole groove 101 on the carrier plate 10 adopt an interference fit or a transition fit, which is used to prevent the fitting portion 113 from sliding or shaking with the carrier plate 10 in the natural state, and can effectively protect the packaged object 2, as ​ and 4b shown

[0094] At this time, define the horizontal distance between the limiting protrusion 1101 and the outward convex structure 1100 as L1, and define the maximum horizontal distance between the two hole grooves 101 on the carrier plate 10 as L2. Then L1 and L2 satisfy the following mathematical relationship: L1 = L2, as ​ and 4b shown. The advantage of this design is that it can prevent the limiting draw bar 110 from moving or shaking on the carrier plate 10 to the greatest extent and protect the packaged object 2

[0095] In this embodiment, after the carrier plate 10 and the fitting portion 113 of the limiting draw bar 110 are fitted, the maximum outer periphery area of the limiting draw bar 110 at the end with the outward convex structure 1100 does not exceed the maximum outer periphery area of the carrier plate 10, which can prevent the operator from misoperating and improve the applicability and aesthetics, as ​ shown

[0096] In another embodiment, an open - type hole 1103 is provided at the limiting draw bar 110 on the side where the convex structure 1100 is provided. The design of the open - type hole 1103 is beneficial to the quick removal of the limiting draw bar 110 after the insertion and fitting. Specifically, when removing the limiting draw bar 110, due to the design of the open - type hole 1103, the convex structure 1100 of the limiting draw bar 110 can achieve a large deformation, facilitating the smooth and stable removal of the limiting draw bar 110 from the card slot 102, as ​ shown.

[0097] Embodiment Three:

[0098] As ​ and 9b shown, this embodiment is based on Embodiment One. The differences between this embodiment and Embodiment One are as follows: The number of the hole - slots 101 on the bearing plate 10 is only one. The fitting part 113 of the limiting draw bar 110 is a flat - plate structure. A quick - insertion structure 1102 is provided on the fitting part 113 of the limiting draw bar 110. The quick - insertion structure 1102 causes the fitting part 113 to undergo elastic deformation, so as to facilitate the portable assembly of the limiting draw bar 110 inserted into the bearing plate 10 while increasing the release force between the fitting part 113 and the hole - slot 101. An outer convex structure 1100 is provided at one end of the fitting part 113 of the limiting draw bar 110 to prevent the limiting draw bar 110 from sliding or shaking relative to the bearing plate 10 in the natural state.

[0099] At this time, define the maximum horizontal distance between the outer convex structure 1100 and the proximal end of the quick - insertion structure 1102 as L3, and define the maximum horizontal distance between the hole - slot 101 and the storage slot 100 as L4. Then L3 and L4 satisfy the following mathematical relationship: L3 = L4, as ​ and 9b shown.

[0100] Embodiment Four:

[0101] As ​ shown, this embodiment is based on Embodiment One. The differences between this embodiment and Embodiment One are as follows: At least two bending structures 13 are provided at the edge position of the bearing plate 10. After bending deformation, the bending structures 13 form a protection cavity 130. The protection cavity 130 is used to accommodate and protect part of the to - be - packaged object 2. At the same time, the bending structures 13 can play a role in supporting the bearing plate 10 to fully protect the to - be - packaged object 2.

[0102] In this embodiment, one bending structure 13 is provided on each of the two sides and the opposite side of the edge position of the bearing plate 10 where the storage slot 100 is located, as ​ and ​ shown. After bending deformation, the bending structures 13 form a protection cavity 130 for accommodating and protecting part of the to - be - packaged object 2.

[0103] In this embodiment, as​ and ​ As shown in ​ , an indication mark 14 is provided on the holding portion 114 of the carrier plate 10 and / or the limiting member 11, facilitating the identification of the disassembly method of the limiting member 11 and the carrier plate 10. The advantage of this design is that the operator can more intuitively distinguish the disassembly method of the packaging liner 1 through the indication mark 14, facilitating the quick and safe removal of the object to be packaged 2, saving the waiting time of the operation, and enhancing the operator's tactile experience.

[0104] In this embodiment, a reinforcement structure 1300 is provided at the bending structure 13 on the carrier plate 10 and / or the limiting member 11, for enhancing the spatial stability of the protection cavity 130 formed by the bending structure 13, enabling the protection cavity 130 to have sufficient strength to support and resist external forces, ensuring that the object to be packaged 2 is not squeezed by external forces and packaging, thereby causing deformation, wear, and damage. As ​ 、 14b shown in 14b , 15a, 15b, 16a, 16b, 17a, 17b, 18a, and 18b, the reinforcement structure 1300 is one or more combinations of a reinforcing rib 13001, a snap-in type reinforcement member 13002, a glue-in type reinforcement member 13003, and a drawstring type reinforcement member 13004, further strengthening the stability and bearing capacity of the protection cavity 130.

[0105] Embodiment Five:

[0106] As ​ shown, based on Embodiment One, the difference between Embodiment Five and Embodiment One is that the limiting member 11 is a limiting flat plate 111, and at least one flap structure 1110 is provided on the fitting portion 113 of the limiting flat plate 111. At least one hole groove 101 is provided on the carrier plate 10, and the hole groove 101 corresponds to the flap structure 1110 in terms of quantity and position. The flap structure 1110 and the hole groove 101 form a mutually cooperating groove structure 12. The shape of the flap structure 1110 is one or more combinations of a circle, a rhombus, a square, an ellipse, and a semi-circle. As ​ a to ​ e shown.

[0107] As ​ shown, in a preferred embodiment, a quick insertion structure 1102 is provided on the fitting portion 113 of the limiting flat plate 111, and the object to be packaged 2 is limited within the limited space formed by the quick insertion structure 1102 and the placement groove 100.

[0108] In the second embodiment, an outward convex structure 1100 is provided on the flap structure 1110, and the outward convex structure 1100 and the hole groove 101 are in interference fit or transition fit, for preventing the limiting flat plate 111 and the carrier plate 10 from sliding or shaking in the natural state, and being able to effectively protect the object to be packaged 2.

[0109] In the third embodiment, an open hole 1103 is provided at the flap structure 1110. The shape of the open hole 1103 is one or a combination of square, circular, T-shaped, I-shaped, and slit-shaped, as ​ shown in a to ​ d. The design of the open hole 1103 is beneficial for quickly taking out the flap structure 1110 of the limiting flat plate 111 from the hole groove 101 of the carrier plate 10. Specifically, when taking out the limiting flat plate 111, due to the design of the open hole 1103, a large deformation can be achieved at the convex structure 1100 of the flap structure 1110, facilitating the smooth removal of the limiting drawbar 110 from the card slot 102.

[0110] In the fourth embodiment, a protective cavity 130 with a three-dimensional structure can be provided at the fitting portion 113 of the limiting flat plate 111 to protect part of the to-be-packaged object 2, as ​ shown in ​ and

[0111] Example 6:

[0112] Based on Example 4, the difference between Example 6 and Example 4 is that a height support structure 103 is provided at the end of the object placement groove 100 on the carrier plate 10. The height support structure 103 has a three-dimensional structure and can protect the waist of a specific to-be-packaged object 2 to prevent it from vertically shaking. For example, for some left atrial appendage occluders with a large distance between the occlusion disc and the anchor frame, their waists are often long. The height support structure 103 can effectively protect the waist of the left atrial appendage occluder and prevent its waist from having a large degree of freedom of movement in the packaging liner 1 and vertically shaking, thereby avoiding secondary damage to the product during transportation, as ​ shown in

[0113] Example 7:

[0114] As ​As shown, based on Embodiment IV, the difference between Embodiment VII and Embodiment IV is that the limiting member 11 is a limiting drawer 112. The fitting portion 113 of the limiting drawer 112 has a three-dimensional structure and forms at least one protection cavity 130. The protection cavity 130 is used to accommodate and protect part of the articles to be packaged 2. The advantage of this design is that the protection cavity 130 provides more comprehensive protection for the articles to be packaged 2, preventing the articles to be packaged 2 from being damaged during transportation and use. At this time, at least one card slot 102 is provided on both the bearing plate 10 and the fitting portion 113 of the limiting drawer 112. The card slots 102 on the fitting portion 113 and the card slots 102 on the bearing plate 10 correspond to each other in number and position. The card slot 102 is a semi-through structure and constitutes a mutually cooperating slot structure 12, enabling the limiting drawer 112 to be separated and disassembled from the bearing plate 10 by horizontal movement.

[0115] Embodiment VIII

[0116] Based on Embodiment I, the difference between Embodiment VIII and Embodiment I is that two layers of bearing plates 10 are provided on the packaging liner 1. The two layers of bearing plates 10 are parallel structures that are symmetrically arranged up and down. One of them is defined as the upper bearing plate 104, and the other is defined as the lower bearing plate 105. In one embodiment, the upper bearing plate 104 and the lower bearing plate 105 can be connected and fixed by one or more combinations of bending, mechanical fitting, and gluing. The space between the upper bearing plate 104 and the lower bearing plate 105 forms a protection cavity 130, which can effectively protect the articles to be packaged 2, as ​ shown.

[0117] In another embodiment, a limiting drawbar 110 is provided between the upper bearing plate 104 and the lower bearing plate 105. At this time, the upper bearing plate 104, the limiting drawbar 110, and the lower bearing plate 105 are in a fitting state. The upper bearing plate 104 and the lower bearing plate 105 are fixed by mechanical fitting and / or gluing. The edges of the upper bearing plate 104 and the lower bearing plate 105 are provided with bending structures 13. The bending structures 13 form a protection cavity 130 by bending, so as to protect the articles to be packaged 2, as ​ shown.
