Description

Technical Field

[0001] This utility model relates to a buffer device, and more particularly to a one-piece molded buffer device. Background Technology

[0002] To prevent product damage from collisions during transportation, manufacturers often use cushioning devices to cover the corners of products for protection. For example, most repair kits currently use a rectangular frame of expanded polyethylene foam (EPE) with two EPE sheets on top and bottom to facilitate assembly on the production line.

[0003] Generally, the molding method for rectangular EPE sheets is mostly 2D axial machining. Since EPE die-cutting is done using 2D axial machining, EPE designs are typically based on 2D planar thinking, which can easily limit the process to methods like hole cutting or manual gluing and bonding. Therefore, when designing products requiring thickness, it's easy to generate waste material in the middle of the sheet, or to require adhesive bonding, resulting in more steps and higher processing costs.

[0073] Figure 1A This is a perspective view of a buffer device according to an embodiment of the present invention. Figure 1B yes Figure 1A A plan view of the buffer device. Figure 2 yes Figure 1A A three-dimensional schematic diagram of the buffer device in another state. Figure 3 yes Figure 2 A three-dimensional diagram of a cushioning device used for packaging products.

[0074] Please refer to this first. Figure 1A The cushioning device 100 in this embodiment includes a body 10. The body 10 includes a first block 110 and a second block 120, and has a first bent portion R1 located between the first block 110 and the second block 120. The first block 110 and the second block 120 are integrally formed. In this embodiment, the body 10 is made of expanded polystyrene (EPE) foam to achieve a cushioning effect, but the material of the body 10 is not limited to this.

[0075] In this embodiment, the first block 110 and the second block 120 can be bent into shape by the first bending portion R1 for packaging products, but this utility model is not limited thereto.

[0076] In this embodiment, the first bending portion R1 extends along the first direction N1. The first bending portion R1 has multiple cutting marks. That is, multiple grooves and protrusions are cut between the first block 110 and the second block 120, and the grooves and protrusions can be movably engaged with each other to achieve an easy bending effect, so that the body 10 can be bent and shaped using the first bending portion R1.

[0077] In the first direction N1, by Figure 1A Viewed from left to right, the first block 110 is first cut with grooves, then with protrusions cut at intervals, and arranged in this pattern. The second block 120 is first cut with protrusions, then with grooves cut at intervals, and arranged in this pattern to correspond to the first block 110, but this invention does not limit this. Here, the cutting lines are not continuous, but multiple segmented cutting lines, so that the first block 110 and the second block 120 are in a state of partial connection (not cut) and partial non-connection (cut off).

[0078] For details, please refer to Figure 1BIn this embodiment, the first bent portion R1 has a first intermediate region R11 and a first peripheral region R12, with the first peripheral region R12 located on opposite sides of the first intermediate region R11. The first block 110 includes at least one first connecting structure 111 in the first intermediate region R11. The second block 120 includes at least one second connecting structure 121 corresponding to the at least one first connecting structure 111 in the first intermediate region R11. The first connecting structure 111 is movably connected to the second connecting structure 121. The shapes of the first connecting structure 111 and the second connecting structure 121 correspond (e.g., are square) so that they can engage with each other. Here, the first connecting structure 111 is a protrusion and the second connecting structure 121 is a groove, but this invention does not limit this.

[0079] In this embodiment, the first block 110 includes two third connecting structures 112, respectively disposed on opposite sides of the first peripheral regions R12 of the first intermediate region R11. The second block 120 includes two fourth connecting structures 122 corresponding to the two third connecting structures 112. The fourth connecting structures 122 are movably connected to the third connecting structures 112. The shapes of the fourth connecting structures 122 and the third connecting structures 112 correspond (e.g., they are square) so that they can engage with each other. Here, the fourth connecting structure 122 is a protrusion and the third connecting structure 112 is a groove, but this invention does not limit this.

[0080] In this embodiment, a first spacing portion E1 is provided between each of the opposite sides of the first intermediate region R11 and the first peripheral region R12. The length X2 of the first spacing portion E1 in the first direction N1 is less than the length X1 of the first spacing portion E1 in the second direction N2. Here, the first direction N1 is perpendicular to the second direction N2. In one embodiment, as... Figure 2 As shown, when the first block 110 and the second block 120 are folded together by the first bending portion R1, the first gap portion E1 will be stretched and deformed.

[0081] Specifically, in this embodiment, the number of first connecting structures 111 and second connecting structures 121 corresponds and there are multiple such structures. Furthermore, the second block 120 further includes multiple fifth connecting structures 123 in the first intermediate region R11. The first block 110 includes multiple sixth connecting structures 113 corresponding to the fifth connecting structures 123 in the first intermediate region R11. The fifth connecting structures 123 are movably connected to the sixth connecting structures 113. The shapes of the fifth connecting structures 123 and the sixth connecting structures 113 correspond to each other and can engage. Here, the fifth connecting structure 123 is a protrusion and the sixth connecting structure 113 is a groove, but this invention does not limit this.

[0082] In this embodiment, the first connecting structure 111 and the fifth connecting structure 123 are arranged alternately. A second spacing portion E2 is provided between the first connecting structure 111 and the fifth connecting structure 123. Figure 1B As shown, the length X4 of the second spacing portion E2 in the first direction N1 is less than the length X3 of the second spacing portion E2 in the second direction N2. Figure 2 As shown, in one embodiment, when the first block 110 and the second block 120 are folded over with the first bending portion R1, the second spacer portion E2 will be stretched and deformed in the same way as the first spacer portion E1.

[0083] For more details, please refer to Figure 2 In this embodiment, when the first block 110 and the second block 120 are folded together by the first bending portion R1, a first surface F1 of the first connecting structure 111 is exposed to the second connecting structure 121, and a second surface F2 of the fourth connecting structure 122 is exposed to the third connecting structure 112. The first block 110 and the second block 120 have a first bending angle, which is, for example, 90 degrees, but this invention is not limited to this. Please refer to... Figure 3 The bent cushioning device 100 is adapted to multiple corners of the packaging element 50 to provide a cushioning effect, but this invention is not limited thereto. When the first block 110 and the second block 120... Figure 2 The bending state is transformed to Figure 1A When the blocks are flattened, the first block 110 and the second block 120 are unfolded relative to each other. The first surface F1 of the first connecting structure 111 is covered by the second connecting structure 121, and the second surface F2 of the fourth connecting structure 122 is covered by the third connecting structure 112.

[0084] In the above configuration, the first block 110 and the second block 120 are partially connected (uncut, e.g., a spacer) and partially disconnected (cut, e.g., a connecting structure). Through a special die-cutting design, the first block 110 and the second block 120 can form a bent and fixed angle after relative rotation, breaking through the original material and processing limitations of the foam material. As a result, the cushioning device 100 can be bent and shaped, and can be flattened for feeding, which is not only more economical, but also reduces waste generation, saves storage space and transportation costs, thereby achieving the benefits of low carbon emissions and waste reduction. In addition, even if the first bent part R1 is damaged after multiple uses (e.g., the spacer is broken), the cushioning device 100 can maintain its flattened or bent state through the engaging function of the connecting structure (e.g., a protrusion and a groove), improving the reuse rate.

[0085] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals representing the same or similar components, and descriptions of identical technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

Figure 5 yes Figure 4A A three-dimensional schematic diagram of the buffer device in another state. Please refer to... Figures 4A to 5 The buffer device 100B in this embodiment includes a body 10B. The body 10B includes a first block 110B and a second block 120B. The first block 110B and the second block 120B are integrally formed.

[0087] In this embodiment, the first block 110 includes a first connecting structure 111B in the first intermediate region R11. The second block 120B includes a second connecting structure 121B corresponding to the first connecting structure 111B in the first intermediate region R11. The first connecting structure 111B is movably connected to the second connecting structure 121B. The shapes of the first connecting structure 111B and the second connecting structure 121B correspond to each other and can mesh with each other. Here, the first connecting structure 111B is a groove and the second connecting structure 121B is a protrusion, but this utility model does not limit this.

[0088] In this embodiment, the first block 110B includes two third connecting structures 112B in the first peripheral region R12. The second block 120B includes two fourth connecting structures 122B corresponding to the two third connecting structures 112B in the first peripheral region R12. The third connecting structures 112B are movably connected to the fourth connecting structures 122B. The shapes of the fourth connecting structures 122B and the third connecting structures 112B correspond to each other and can mesh with each other. Here, the fourth connecting structure 122B is a groove and the third connecting structure 112B is a protrusion, but this utility model does not limit this. In this embodiment, a first gap E1 is provided between the opposite sides of the first intermediate region R11 and the first peripheral region R12.

[0089] Furthermore, the first block 110B includes a first portion P1 and a second portion P2. One end of the second portion P2 is connected to the first bend R1, and the other end of the second portion P2 is connected to the first portion P1. The first portion P1 includes a first engaging portion K1. The body 10B has a second bend R2 located between the first portion P1 and the second portion P2.

[0090] In this embodiment, the second block 120 includes a third part P3 and a fourth part P4.

The body 10 has a third bend R3 located between the third part P3 and the fourth part P4.

[0091] Here, the second bend R2 and the third bend R3 are similar to the first bend R1, also having multiple cut lines. That is, the first part P1 and the second part P2, as well as the third part P3 and the fourth part P4, are cut to create multiple spaced-apart connection structures. For example, grooves and protrusions can be movably engaged with each other to achieve an easy bending effect, so that the body 10B can be bent using the first bend R1, the second bend R2, and the third bend R3.

[0092] In this embodiment, when the first part P1, the second part P2, the third part P3 and the fourth part P4 are unfolded, the first part P1, the second part P2, the third part P3 and the fourth part P4 extend in the same direction.

[0093] In this embodiment, when the body 10B is bent using the first bending portion R1, the second bending portion R2, and the third bending portion R3, the first part P1, the second part P2, the third part P3, and the fourth part P4 form a square frame, and the first engaging portion K1 engages with the second engaging portion K2. Here, the first engaging portion K1 is a slot, and the second engaging portion K2 is a block; they can interlock to fix the square frame and prevent it from falling apart. In this way, by using the buffer device 100B to bend and shape the product to cover the corners, effective protection can be achieved. Furthermore, by disassembling the first engaging portion K1 and the second engaging portion K2, the body 10B can be flattened and returned to the form of a flat sheet.

Here, the fifth connecting structure 131C is a protrusion and the sixth connecting structure 113C is a groove, but the present invention does not limit this.

[0099] In this embodiment, the first block 110C includes two seventh connecting structures 114C in the second peripheral region R22, and the third block 130C includes two eighth connecting structures 132C corresponding to the two seventh connecting structures 114C in the second peripheral region R22.

Here, the seventh connecting structure 114C is a protrusion and the eighth connecting structure 132C is a groove, but this utility model does not limit this.

[0100] In this embodiment, a third spacer E3 is provided between each of the opposite sides of the second intermediate region R21 and the second peripheral region R22. When the first block 110C and the third block 130C are folded over by the second bending portion R2, the third spacer E3 will be stretched and deformed.

[0101] In this embodiment, the second block 120C includes a first engaging portion K3, and the third block 130C includes a second engaging portion K4. Here, the first engaging portion K3 is a slot, and the second engaging portion K4 is a locking block, which can lock together to achieve a fixing effect.

[0102] When the second block 120C and the first block 110C are folded together by the first bending portion R1, and the third block 130C and the first block 110C are folded together by the second bending portion R2, the first engaging portion K3 engages with the second engaging portion K4. The first block 110C, the second block 120C, and the third block 130C form a three-dimensional shape with three mutually perpendicular surfaces, which reduces the material bonding process and avoids waste. In this way, by using the cushioning device 100C to bend and shape the product to cover it, effective protection can be achieved.

[0103] In summary, in the buffer device of this utility model, a first bending portion is provided between the first block and the second block. The first connecting structure of the first block is movably connected to the second connecting structure of the second block, and the fourth connecting structure of the second block is movably connected to the third connecting structure of the first block. There is a gap between the first and third connecting structures, and a gap between the second and fourth connecting structures, resulting in partial connection and partial non-connection between the first and second blocks. Therefore, the buffer device can be bent into shape without springing back, effectively protecting the product, overcoming the material and processing limitations of the original foam material, and reducing waste generation during manufacturing, saving storage space and transportation costs.
