Description

Technical Field

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

[0002] In the current field of product transport packaging, using packaging materials as cushioning materials to protect products from impact damage is a commonly used technical means. Currently, conventional packaging materials usually adopt a split structure design, that is, additional positioning packaging materials or auxiliary fixing components are added outside the main packaging material structure, and the product is stably clamped by stacking and combining multiple packaging materials.

[0003] However, while such packaging technology can provide basic cushioning, significant drawbacks have been found in practical applications. First, the additional packaging materials require additional cutting processes and different installation sequences during packaging (e.g., adhesive application), which significantly increases packaging manufacturing costs and weakens the product's price advantage in the market. Second, the multi-component assembly structure makes it extremely easy for auxiliary packaging materials to scatter and be lost when end users disassemble the packaging, affecting the product's secondary packaging requirements. Therefore, improvements are urgently needed. Utility Model Content

[0004] The main purpose of this utility model is to propose a packaging structure that solves the problem of increased costs caused by the need to add additional auxiliary packaging materials during packaging in related technologies.

[0005] To achieve the above objectives, this utility model proposes a packaging structure, comprising:

[0006] The packaging material body has a mounting groove for storing the packaged item, and the packaging material body has a first sidewall and a second sidewall disposed on two opposite sides of the mounting groove.

[0007] A fixed arm, one end of which is connected to the first sidewall, and the other end of which extends away from the mounting groove. The fixed arm is provided with a snap-fit ​​groove, the opening of which faces the second sidewall.

[0008] A flexible snap-fit ​​arm, one end of which is connected to the second sidewall, and the other end of which extends away from the mounting groove. The flexible snap-fit ​​arm can be bent and snap-fit ​​with the snap-fit ​​groove.

[0009] In some embodiments, the flexible snap-fit ​​arm is provided with a bending groove, the opening of the bending groove is provided facing the fixed arm, and the flexible snap-fit ​​arm is bent at the position of the bending groove.

[0010] In some embodiments, the cross-section of the bending groove is arranged in a triangular structure.

[0011] In some embodiments, the end of the flexible snap-fit ​​arm away from the mounting groove is chamfered, and the contour of the snap-fit ​​groove is adapted to the end of the flexible snap-fit ​​arm away from the mounting groove.

[0012] In some embodiments, a protrusion is provided on the side of the flexible snap-fit ​​arm facing away from the fixed arm. When the flexible snap-fit ​​arm is snapped into the snap-fit ​​groove, the protrusion and the end of the fixed arm away from the mounting groove are located on the same horizontal plane.

[0013] In some embodiments, the snap-fit ​​groove is provided with a limiting groove facing the groove wall of the mounting groove, and the flexible snap-fit ​​arm is provided with a limiting rib corresponding to the limiting groove.

[0014] In some embodiments, the packaging structure is provided with a plurality of fixed arms and a plurality of flexible snap-fit ​​arms, with each fixed arm corresponding to each flexible snap-fit ​​arm.

[0015] In some embodiments, the packaging body, the fixing arm, and the flexible snap-fit ​​arm are integrally formed.

[0016] In some embodiments, the packaging body, the fixing arm, and the flexible snap-fit ​​arm are made of at least one of the following: polyethylene foam (EPE), ethylene-vinyl acetate copolymer (EVA), chemically cross-linked polyethylene foam (XPE), polyurethane (PU), silicone rubber, and thermoplastic polyurethane (TPU).

[0017] The beneficial effects of this utility model's technical solution are as follows:

[0018] This utility model's packaging structure features an installation groove on the packaging material body, and fixed arms and flexible snap-fit ​​arms on opposite sides of the installation groove. The fixed arms have snap-fit ​​grooves, while the flexible snap-fit ​​arms can be bent and snap-fit ​​with the snap-fit ​​grooves. This allows the packaged item to be placed in the installation groove, and when the flexible snap-fit ​​arm bends and snaps into the snap-fit ​​groove, it can seal the opening of the installation groove, fixing the packaged item inside. Furthermore, the packaged item is surrounded by the packaging structure on all sides, achieving the cushioning effect of the packaging structure without the need for additional packaging materials. The snap-fit ​​design of the fixed arms and flexible snap-fit ​​arms also enables a self-locking function for a single piece of packaging material. This integrated design shortens the disassembly and assembly time, and the snap-fit ​​structure can be reused during secondary packaging, effectively solving the problem of lost additional packaging material components.

[0027] The solutions in the embodiments of this utility model 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 utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. In addition, the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0028] To address the technical deficiencies in related technologies, this utility model provides a packaging structure. Please refer to [link / reference]. Figures 1 to 4 It includes: a packaging material body 100, a fixing arm 200, and a flexible snap-fit ​​arm 300. The packaging material body 100 has a mounting groove 110 for storing the item to be packaged. The mounting groove 110 can be a square groove, an arc groove, or a groove formed in other ways. Specifically, the shape of the mounting groove 110 is adapted to the shape of the item to be packaged, so that the item to be packaged can be stored in the mounting groove 110 in a changeable manner and is wrapped by the groove wall of the mounting groove 110 to achieve better cushioning.

[0029] Specifically, the packaging body 100 has a first sidewall 111 and a second sidewall 112 located on two opposite sides of the mounting groove 110. One end of the fixing arm 200 is connected to the first sidewall 111, and the other end of the fixing arm 200 extends away from the mounting groove 110. The fixing arm 200 is provided with a snap-fit ​​groove 210, and the opening of the snap-fit ​​groove 210 faces the second sidewall 112. One end of the flexible snap-fit ​​arm 300 is connected to the second sidewall 112, and the other end of the flexible snap-fit ​​arm 300 extends away from the mounting groove 110. The flexible snap-fit ​​arm 300 can be bent and snap-fit ​​with the snap-fit ​​groove 210.

[0030] It should be noted that the fixing arm 200 and the flexible snap-fit ​​arm 300 can exist separately and be connected to the packaging body 100 by adhesive bonding. In this embodiment, the fixing arm 200 and the flexible snap-fit ​​arm 300 can also be integrally formed with the packaging body 100, for example by cutting or foaming. The connection method between the fixing arm 200 and the flexible snap-fit ​​arm 300 and the packaging body 100 is not specifically limited here.

[0031] In addition, the packaging body 100, the fixing arm 200 and the flexible snap-fit ​​arm 300 are made of at least one of the following materials: polyethylene foam (EPE), ethylene-vinyl acetate copolymer (EVA), chemically cross-linked polyethylene foam (XPE), polyurethane (PU), silicone rubber and thermoplastic polyurethane (TPU); that is, the packaging body 100, the fixing arm 200 and the flexible snap-fit ​​arm 300 can be made of a single material or a composite of the above materials. The specific materials used for the packaging body 100, the fixing arm 200 and the flexible snap-fit ​​arm 300 are not limited here.

[0032] Through the above technical solution, the packaging structure of this utility model provides an installation groove 110 on the packaging material body 100, and provides a fixed arm 200 and a flexible snap-fit ​​arm 300 on two opposite sides of the installation groove 110. The fixed arm 200 is provided with a snap-fit ​​groove 210, and the flexible snap-fit ​​arm 300 can be bent and snap-fit ​​with the snap-fit ​​groove 210. When the packaged item is placed in the installation groove 110, the flexible snap-fit ​​arm 300 can be bent and snap-fit ​​with the snap-fit ​​groove 210 to cover the opening of the installation groove 110, fixing the packaged item in the installation groove 110. The packaged item can be surrounded by the packaging structure on all four sides, achieving the cushioning effect of the packaging structure without the need for additional packaging material. Furthermore, through the snap-fit ​​cooperation structure design of the fixed arm 200 and the flexible snap-fit ​​arm 300, a self-locking fixing function of a single packaging material is achieved. This integrated design shortens the disassembly and assembly time, and the snap-fit ​​structure can be reused during secondary packaging, thereby effectively solving the problem of lost additional packaging material components.

[0033] To facilitate better bending of the flexible snap-fit ​​arm 300, in this embodiment, the flexible snap-fit ​​arm 300 is provided with a bending groove 310. The opening of the bending groove 310 faces the fixed arm 200, and the flexible snap-fit ​​arm 300 is bent at the position of the bending groove 310. The design of the bending groove 310 enables the flexible snap-fit ​​arm 300 to have a precise deformation guiding function, the bending angle can be controlled, ensuring standardized operation of the snap-fit ​​action, and maintaining good flexibility even after multiple bends.

[0034] Specifically, the bending groove 310 has a triangular cross-section. This triangular cross-section bending groove 310 forms a double-sloping stress-guiding structure, reducing material tension during bending, preventing crack propagation after bending, and extending the service life of the flexible snap-fit ​​arm 300 during bending.

[0035] In some embodiments, the end of the flexible snap-fit ​​arm 300 away from the mounting groove 110 is chamfered 320, and the contour of the snap-fit ​​groove 210 is adapted to the end of the flexible snap-fit ​​arm 300 away from the mounting groove 110. This configuration allows the end of the flexible snap-fit ​​arm 300 away from the mounting groove 110 to easily engage with the snap-fit ​​groove 210, facilitating the user's snap-fit ​​operation after bending the flexible snap-fit ​​arm 300.

[0036] After the flexible snap-fit ​​arm 300 is snapped into the snap-fit ​​slot 210, the plane of the end of the flexible snap-fit ​​arm 300 facing away from the fixed arm 200 will be set at a perpendicular angle to the extension direction of the fixed arm 200. As a result, the flexible snap-fit ​​arm 300 will bend and the side facing away from the mounting slot 110 will be suspended in mid-air. The cushioning structure at this point is weak and not conducive to cushioning. Therefore, please refer to... Figures 5 to 6 In this embodiment, a protrusion 330 is provided on the side of the flexible snap-fit ​​arm 300 facing away from the fixed arm 200. When the flexible snap-fit ​​arm 300 is snapped into the snap-fit ​​groove 210, the protrusion 330 and the end of the fixed arm 200 away from the mounting groove 110 are on the same horizontal plane. This arrangement ensures that after the flexible snap-fit ​​arm 300 is bent, the protrusion 330 can fill the position where the side of the flexible snap-fit ​​arm 300 facing away from the mounting groove 110 will be suspended after bending, thereby increasing the buffer thickness.

[0037] In addition, please continue to refer to Figures 5 to 6 To ensure a more secure and reliable engagement between the flexible snap-fit ​​arm 300 and the snap-fit ​​groove 210, in some embodiments, the snap-fit ​​groove 210 has a limiting groove 220 facing the groove wall of the mounting groove 110, and the flexible snap-fit ​​arm 300 has a limiting rib 340 corresponding to the limiting groove 220. Thus, the cooperation between the limiting groove 220 and the limiting rib 340 forms a second-level snap-fit ​​effect, which can significantly improve vibration and impact resistance, prevent accidental loosening due to external forces during transportation, and enhance the reliability of the packaging.

[0038] In this embodiment, the packaging structure is provided with multiple fixed arms 200 and multiple flexible snap-fit ​​arms 300, with each fixed arm 200 corresponding to one flexible snap-fit ​​arm 300. The multiple flexible snap-fit ​​arms 300 and the multiple fixed arms 200 form a snap-fit ​​connection, which can enhance the wrapping force of the packaging structure and can flexibly adjust the layout according to the product size to achieve uniform force distribution and modular expansion capability, adapting to the packaging needs of products of different specifications.

[0039] In this embodiment, the packaging body 100, the fixing arm 200, and the flexible snap-fit ​​arm 300 are integrally molded. The integral molding process simplifies the production process, reduces mold wear, eliminates structural weaknesses in traditional assembly, significantly improves overall structural strength and yield, and reduces manufacturing costs.

[0040] In addition, the packaging body 100, the fixing arm 200 and the flexible snap-fit ​​arm 300 are all made of polyethylene foam. The polyethylene foam maintains stable cushioning performance and flexibility in a wide temperature range environment, and can be recycled and reused, taking into account both product protection needs and sustainable development requirements.

[0041] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
