Description

Technical Field

[0001] The utility model relates to the field of packaging cartons, in particular to an elastic supporting structure in a packaging carton with strong versatility. Background Art

[0002] As we all know, some commodities cannot be subjected to excessive vibration, collision, or extrusion during the packaging and logistics process. Therefore, during the packaging and transportation process, it is necessary to set elastic lining or elastic materials in the packaging box of such commodities for elastic support and protection to ensure that they will not be damaged during transportation and handling. At present, the packaging of such commodities generally adopts the packaging method of padding foam, lining or pad inside the carton, and the foam has non-degradable white pollution, and its use will be gradually restricted in the future. Although the lining can be designed to have a certain elastic support capacity, because the commodities packaged in the packaging box are varied and of different shapes, the mechanism often designed to adapt to the commodities is relatively complex, the manufacturing cost is high, and the manufacturing speed is slow. It is difficult to design a packaging lining with strong versatility that can be suitable for a variety of commodities. Although the lining also has a certain elastic support function, its elastic support capacity is limited, and it is not applicable to some more precise commodities or commodities with high requirements on the surface appearance of commodities.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0028] Example 1.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, a highly versatile elastic support structure in a packaging carton comprises a rectangular cardboard body, which is divided into long sheets of A folding plate 1, B folding plate 2, C folding plate 3, D folding plate 4, E folding plate 5, F folding plate 6, G folding plate 7, H folding plate 8, I folding plate 9, J folding plate 10, K folding plate 11, L folding plate 12 and M folding plate 13 from left to right, and the B folding plate 2, C folding plate 3, E folding plate 5 and F folding plate 6 have the same width, the D folding plate 4 has the same width as the G folding plate 7, the H folding plate 8, I folding plate 9, K folding plate 11 and L folding plate 12 have the same width, and the J folding plate 10 and M folding plate 13 have the same width;

[0030] like Figure 7 and Figure 8 As shown, a buckle 14 is punched out on both sides of the middle part of the J folding plate 10 and the M folding plate 13 in the front-to-back direction, and a buckle 15 can be made after pressing down one side of the buckle 14, and the positions of the two buckles 14 on the J folding plate 10 correspond to the same positions of the two buckles 14 on the M folding plate 13;

[0031] Positive fold lines 16 are punched out between the A folding plate 1 and the B folding plate 2, between the C folding plate 3 and the D folding plate 4, between the D folding plate 4 and the E folding plate 5, between the F folding plate 6 and the G folding plate 7, between the G folding plate 7 and the H folding plate 8, between the I folding plate 9 and the J folding plate 10, between the J folding plate 10 and the K folding plate 11, and between the L folding plate 12 and the M folding plate 13. Negative fold lines 17 are punched out between the B folding plate 2 and the C folding plate 3, between the E folding plate 5 and the F folding plate 6, between the H folding plate 8 and the I folding plate 9, and between the K folding plate 11 and the L folding plate 12.

[0032] After folding and forming, the A folding plate 1 is located on the left side of the top innermost layer of the elastic supporting structure, the B folding plate 2 and the C folding plate 3 are respectively located at the upper and lower parts of the left inner layer of the elastic supporting structure, the D folding plate 4 is located at the bottom inner layer of the elastic supporting structure, the E folding plate 5 and the F folding plate 6 are respectively located at the lower and upper parts of the right inner layer of the elastic supporting structure, the G folding plate 7 is located at the top middle layer of the elastic supporting structure, the H folding plate 8 and the I folding plate 9 are respectively located at the upper and lower parts of the left outer layer of the elastic supporting structure, the J folding plate 10 is located at the bottom outer layer of the elastic supporting structure, the K folding plate 11 and the L folding plate 12 are respectively located at the lower and upper parts of the right outer layer of the elastic supporting structure, and the M folding plate 13 is located at the top outermost layer of the elastic supporting structure; the movable ends of the two buckles 14 on the M folding plate 13 and the J folding plate 10 are respectively pressed down and passed through the bayonet 15 and are respectively clamped under the two bayonet 15 of the J folding plate 10, and the M folding plate 13 is fixed to the top of the elastic supporting structure.

[0033] The width of the A folding plate 1 is consistent with the distance from the buckle 14 to the right side of the M folding plate 13, and when the buckle 14 is inserted into the bayonet 15 when the elastic support structure is folded and formed, the end of the A folding plate 1 is stuck in the angle gap between the buckle 14 and the G folding plate 7. In this way, when the top of the elastic support structure is compressed, the inner end of the A folding plate 1 will press against the upper end of the buckle 14, which is equivalent to applying a pressing force to the upper end of the buckle 14, and has a certain rebound force on the buckle 14, which will be transmitted outward along the A folding plate 1, so that the entire elastic support structure has an elastic support function.

[0034] At the same time, the buckle 14 and the bayonet 15 are both trapezoidal structures, and the part surrounded by the long bottom side and the two side sides of the buckle 14 is the movable part 141 where the buckle 14 is located, and the short bottom side of the buckle 14 is the fixed part 142. The movable part 141 is located in the bayonet 15, and the fixed part 142 is fixed on the middle part of the J folding plate 10 or the M folding plate 13, and the movable part 141 can be folded around the fixed part 142 in the bayonet 15. This design not only increases the width of the movable end of the buckle 14, which is convenient for people to press with their fingers, but also reduces the width of the connection between the buckle 14 and the J folding plate 10 or the M folding plate 13, minimizing the impact on the overall support strength of the J folding plate 10 or the M folding plate 13.

[0035] In the folding process of the highly versatile elastic support structure in the packaging carton in this example, where there is a positive fold line 16 between two adjacent fold plates, the two fold plates are folded forward along the positive fold line 16, and where there is a negative fold line 17 between two adjacent fold plates, the two fold plates are folded backward along the negative fold line 17. After folding, the M fold plate 13 is located on the top surface of the elastic support structure, and the J fold plate 10 is located on the bottom surface of the elastic support structure, and the J fold plate 10 and the M fold plate 13 are parallel to each other.

[0036] Example 2.

[0037] like Figure 4 , Figure 5 and Figure 6 As shown, a highly versatile elastic support structure in a packaging carton comprises a rectangular cardboard body, which is divided into long sheets of A folding plate 1, B folding plate 2, C folding plate 3, D folding plate 4, E folding plate 5, F folding plate 6, G folding plate 7, H folding plate 8, I folding plate 9, J folding plate 10, K folding plate 11, L folding plate 12 and M folding plate 13 from left to right, and the B folding plate 2, C folding plate 3, E folding plate 5 and F folding plate 6 have the same width, the H folding plate 8, I folding plate 9, K folding plate 11 and L folding plate 12 have the same width, and the J folding plate 10 and M folding plate 13 have the same width;

[0038] like Figure 7 and Figure 8As shown, a buckle 14 is punched out on both sides of the middle part of the J folding plate 10 and the M folding plate 13 in the front-to-back direction, and a buckle 15 can be made after pressing down one side of the buckle 14, and the positions of the two buckles 14 on the J folding plate 10 correspond to the same positions of the two buckles 14 on the M folding plate 13;

[0039] Positive fold lines 16 are punched out between the A folding plate 1 and the B folding plate 2, between the C folding plate 3 and the D folding plate 4, between the D folding plate 4 and the E folding plate 5, between the F folding plate 6 and the G folding plate 7, between the G folding plate 7 and the H folding plate 8, between the I folding plate 9 and the J folding plate 10, between the J folding plate 10 and the K folding plate 11, and between the L folding plate 12 and the M folding plate 13. Reverse fold lines are punched out between the B folding plate 2 and the C folding plate 3, between the E folding plate 5 and the F folding plate 6, between the H folding plate 8 and the I folding plate 9, and between the K folding plate 11 and the L folding plate 12. The width of the D folding plate 4 is greater than the width of the G folding plate 7, and a middle reverse fold line 18 is punched out in the middle of the D folding plate 4 along the front-to-back direction, and the D folding plate 4 is equally divided into a 1D folding plate 41 and a 2D folding plate 42 by the middle reverse fold line 18.

[0040] After folding and forming, the A folding plate 1 is located on the left side of the top innermost layer of the elastic support structure, the B folding plate 2 and the C folding plate 3 are respectively located at the upper and lower parts of the left inner layer of the elastic support structure, and the 1D folding plate 41 and the 2D folding plate 42 are both folded upward at one end near the middle inflection line 18, and after folding, an isosceles triangular prism-shaped elastic support body 19 is formed between the 1D folding plate 41, the 2D folding plate 42 and the J folding plate 10. The E folding plate 5 and the F folding plate 6 are respectively located at the lower and upper parts of the right inner layer of the elastic support structure, the G folding plate 7 is located at the top middle layer of the elastic support structure, the H folding plate 8 and the I folding plate 9 are respectively located at the upper and lower parts of the left outer layer of the elastic support structure, the J folding plate 10 is located at the bottom outer layer of the elastic support structure, the K folding plate 11 and the L folding plate 12 are respectively located at the lower and upper parts of the right outer layer of the elastic support structure, and the M folding plate 13 is located at the top outermost layer of the elastic support structure; the movable ends 141 of the two buckles 14 on the M folding plate 13 and the J folding plate 10 are respectively pressed down and passed through the bayonet 15, and are respectively clamped under the two bayonet 15 of the J folding plate 10, and the M folding plate 13 is fixed to the topmost part of the elastic support structure.

[0041] The width of the A folding plate 1 is consistent with the distance from the buckle 14 to the right side of the M folding plate 13, and when the buckle 14 is inserted into the bayonet 15 when the elastic support structure is folded and formed, the end of the A folding plate 1 is stuck in the angle gap between the buckle 14 and the G folding plate 7. In this way, when the top of the elastic support structure is compressed, the inner end of the A folding plate 1 will press against the upper end of the buckle 14, which is equivalent to applying a pressing force to the upper end of the buckle 14, and has a certain rebound force on the buckle 14, which will be transmitted outward along the A folding plate 1, so that the entire elastic support structure has an elastic support function.

[0042] like Figure 7 and Figure 8 As shown, the buckle 14 and the bayonet 15 are both trapezoidal structures, and the part surrounded by the long bottom side and the two side sides of the buckle 14 is the movable part 141 where the buckle 14 is located, and the short bottom side of the buckle 14 is the fixed part 142. The movable part 141 is located in the bayonet 15, and the fixed part 142 is fixed on the middle part of the J folding plate 10 or the M folding plate 13, and the movable part 141 can be folded around the fixed part 142 in the bayonet 15. This design not only increases the width of the movable end of the buckle 14, which is convenient for people to press with their fingers, but also reduces the width of the connection between the buckle 14 and the J folding plate 10 or the M folding plate 13, minimizing the impact on the overall support strength of the J folding plate 10 or the M folding plate 13.

[0043] The folding method of the highly versatile elastic support structure in the packaging carton in this example during the folding and forming process is the same as in Example 1, with the difference being that when folded to the D folding plate 4, since the D folding plate 4 is equally divided into a 1D folding plate 41 and a 2D folding plate 42 by the middle inflection line 18, the 1D folding plate 41 and the 2D folding plate 42 are to be folded in the opposite direction along the middle inflection line 18, and an isosceles triangular prism-shaped elastic support body 19 is formed between the folding plate 10 and the J folding plate after folding, thereby achieving a certain supporting function in the middle of the elastic support structure.

[0044] In the above two embodiments, the utility model divides a rectangular cardboard into long sheets of A folding plate 1, B folding plate 2, C folding plate 3, D folding plate 4, E folding plate 5, F folding plate 6, G folding plate 7, H folding plate 8, I folding plate 9, J folding plate 10, K folding plate 11, L folding plate 12 and M folding plate 13 from left to right, and the B folding plate 2, C folding plate 3, E folding plate 5 and F folding plate 6 have the same width, the width of the D folding plate 4 is not less than the width of the G folding plate 7, the H folding plate 8, I folding plate 9, K folding plate 11 and L folding plate 12 have the same width, and the J folding plate 10 and M folding plate 13 have the same width. A buckle 14 is punched on both sides of the middle part of the J folding plate 10 and the M folding plate 13 in the front-to-back direction, and a snap hole 15 can be made after pressing down the movable part 141 on one side of the buckle 14, and the positions of the two buckles 14 on the J folding plate 10 correspond to the positions of the two buckles 14 on the M folding plate 13. By folding the A folding plate 1, the B folding plate 2, the C folding plate 3, the D folding plate 4, the E folding plate 5, the F folding plate 6, the G folding plate 7, the H folding plate 8, the I folding plate 9, the J folding plate 10, the K folding plate 11, the L folding plate 12 and the M folding plate 13 in sequence, the folding plate 10, the B folding plate 2, the C folding plate 3, the D folding plate 4, the E folding plate 5, the F folding plate 6, the G folding plate 7, the H folding plate 8, the I folding plate 9, the J folding plate 10, the K folding plate 11, the L folding plate 12 and the M folding plate 13 are formed into a long three-dimensional elastic support structure. When used as an inner pad for commodity packaging, whether it is placed at the bottom or side of the commodity, it has a good elastic support ability and can well reduce the shock of the packaged commodity. It has strong versatility and can meet the elastic packaging support requirements of various commodities. It has a fast manufacturing speed and a low manufacturing cost. Thereby achieving the purpose of novel design, reasonable structure and good application effect.

[0045] The above is only a preferred implementation of the elastic support structure in the packaging carton with high versatility of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all belong to the protection scope of the utility model.
