Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a tear strip for an easily openable corrugated cardboard box. Background Art

[0002] In the prior art, an Easys strip is adhered at the bag opening of a package through double-sided tape. With the tear opening formed by the cooperation of the package, after the package is sealed, the package can only be opened by damaging the package from the tear opening.

[0003] For existing tear strips, for cardboard boxes such as corrugated cardboard boxes, they need to be formed by cutting cardboard. The strip is a rectangular strip structure, and waves of sawteeth are formed on the other side of the strip. Then, two tear strips can be formed by one-time cutting during cutting. However, for the utilization of the whole piece of board, due to the shape of the sawteeth, a certain gap needs to be reserved during the cutting process to ensure the integrity of the two cut strips, resulting in limited overall utilization rate of the board. Therefore, it is necessary to optimize the shape of the strip to reduce the loss of the board and improve the production rate, and then optimize the production process.

[0004] Therefore, we propose a tear strip for an easily openable corrugated cardboard box. Content of the Utility Model

[0005] The utility model mainly solves the technical problem of low utilization rate of the board caused by the shape of the strip, and provides a tear strip for an easily openable corrugated cardboard box.

[0006] In order to achieve the above object, the utility model adopts the following technical scheme. A tear strip for an easily openable corrugated cardboard box includes:

[0007] A main body, which is a strip structure forming a comb structure. A number of first extension parts are fixedly arranged on one side of the main body, and a first cut groove is formed between two adjacent first extension parts. A number of second extension parts are fixedly arranged on the other side of the main body, and a second cut groove is formed between two adjacent second extension parts. One side of the main body forms a comb structure through the first extension parts and the first cut groove, and the other side of the main body forms a comb structure through the second extension parts and the second cut groove.

[0008] A double-sided tape, which is pasted on one side of the main body for adhering other guaranteed strip structures.

[0009] As a preferred mode of the utility model, the main body is formed by cutting. The first extension part is integrally formed with the main body, and the first extension part forms a convex part with a semicircular cross section. The first cut groove is a semicircular notch.

[0010] As a preferred mode of the utility model, the second extension part is integrally formed with the main body, the cross section of the second extension part is semicircular, and the second cut groove is semicircular.

[0011] As a preferred embodiment of the present utility model, the first extension portions and the second cut grooves are distributed in one-to-one correspondence, the radii of the first extension portions and the second cut grooves are equal, the first cut grooves and the second extension portions are distributed in one-to-one correspondence, and the radii of the first cut grooves and the second extension portions are equal.

[0012] As a preferred embodiment of the present utility model, a plurality of first depressions are formed on one side of the double-sided tape, and an integrally formed first contact portion is provided between two adjacent first depressions. A plurality of second depressions are formed on the other side of the double-sided tape, and an integrally formed second contact portion is provided between two adjacent second depressions.

[0013] As a preferred embodiment of the present utility model, the cross sections of the first depressions and the second contact portions are both semi-circular, the diameters of the first depressions and the second contact portions are equal, and the first depressions and the second contact portions are distributed in one-to-one correspondence.

[0014] As a preferred embodiment of the present utility model, the cross sections of the first contact portions and the second depressions are both semi-circular with equal diameters, and the first contact portions and the first depressions are distributed in one-to-one correspondence.

[0015] The present utility model provides an easily openable corrugated cardboard tearing strip. It has the following beneficial effects:

[0016] 1. For the easily openable corrugated cardboard tearing strip, by providing the first extension portions and the second extension portions, wave crests are formed on the opposite sides of the main body, while wave troughs are formed on the two sides of the main body where the first cut grooves and the second cut grooves are provided. Since the first extension portions and the second cut grooves have the same cross section, and the first cut grooves and the second extension portions have the same cross section, during the process of cutting the main body, when cutting the whole board into multiple main bodies, two adjacent main bodies can be attached to each other, which can reduce the raw material loss caused by cutting, improve the utilization rate, reduce the cost, and optimize the cutting process.

[0017] 2. For the easily openable corrugated cardboard tearing strip, by providing the double-sided tape, one side of the double-sided tape is adhered to the main body, and the other side of the double-sided tape is used to adhere to the packaging to achieve sealing. By providing the first extension portions and the second extension portions, wave crests are formed on the two sides of the main body, and wave troughs are formed in cooperation with the first contact portions and the second contact portions on the two sides of the main body. Similarly, when cutting the double-sided tape, the loss of the tape can also be reduced, and the yield can be improved. At the same time, compared with the flat strip structure in the prior art, the wavy first contact portion has a larger bonding area and better bonding effect.

[0018] 3. The tear strip of the easy-to-open corrugated cardboard box improves the opening efficiency: By integrating the tear strip into the corrugated cardboard structure, users can easily cut the corrugated cardboard with a gentle pull along the tear strip, achieving the rapid opening of the corrugated cardboard box. This greatly simplifies the opening process and improves the opening efficiency. It reduces the manufacturing cost: The design of the tear strip is relatively simple, without the need to add additional complex structures, reducing the manufacturing cost of the cardboard box. At the same time, due to the tight combination of the tear strip and the corrugated cardboard structure, it does not affect the overall strength and stability of the cardboard box. Visually, it is more unified and aesthetically pleasing. The design of the round corners at the outermost edge is neater and will not be too obtrusive to cause waste. The V-shaped tear opening inside is easier to tear, enhancing the user experience. It is environmentally friendly and sustainable: The integrated design of the tear strip and the corrugated cardboard reduces material waste, conforming to the environmental protection concept. At the same time, this design is also easy to recycle and reuse, contributing to the sustainable development of the packaging industry. BRIEF DESCRIPTION OF THE DRAWINGS

A number of second extension parts 22 are fixedly arranged on the other side of the main body 10, and a second cutting groove 23 is formed between two adjacent second extension parts 22. One side of the main body 10 forms a comb structure through the first extension parts 20 and the first cutting groove 21, and the other side of the main body 10 forms a comb structure through the second extension parts 22 and the second cutting groove 23. The main body 10 is formed by cutting. The first extension parts 20 are integrally formed with the main body 10. The first extension parts 20 form protrusions with a semicircular cross-section. The first cutting groove 21 is a semicircular notch. The second extension parts 22 are integrally formed with the main body 10. The cross-section of the second extension parts 22 is semicircular. The second cutting groove 23 is semicircular. The first extension parts 20 and the second cutting grooves 23 are distributed in one-to-one correspondence, and the first extension parts 20 and the second cutting grooves 23 have the same radius. The first cutting grooves 21 and the second extension parts 22 are distributed in one-to-one correspondence, and the first cutting grooves 21 and the second extension parts 22 have the same radius. In this solution, by setting the first extension parts 20 and the second extension parts 22, wave crests are formed on the opposite sides of the main body 10, while wave troughs are formed on the two sides of the main body 10 where the first cutting grooves 21 and the second cutting grooves 23 are opened. Since the first extension parts 20 and the second cutting grooves 23 have the same cross-section, and the first cutting grooves 21 and the second extension parts 22 have the same cross-section, during the process of cutting the main body 10, when the whole board is cut into multiple main bodies 10, two adjacent main bodies 10 can be attached, which can reduce the raw material loss caused by cutting, improve the utilization rate, reduce the cost, and optimize the cutting process.

[0027] As Figure 2 and Figure 4As shown, the double-sided tape 11 is pasted on one side of the main body 10 for bonding other guaranteed strip structures.

The cross-sections of the first recess 31 and the second contact portion 33 are both semi-circular, the diameters of the first recess 31 and the second contact portion 33 are equal, and the first recess 31 and the second contact portion 33 are distributed in a one-to-one correspondence. The cross-sections of the first contact portion 30 and the second recess 32 are both semi-circular with equal diameters, and the first contact portion 30 and the first recess 31 are distributed in a one-to-one correspondence. By providing the double-sided tape 11, one side of the double-sided tape 11 is bonded to the main body 10, and the other side of the double-sided tape 11 is used for bonding with the packaging to achieve sealing. By providing the first extension portion 20 and the second extension portion 22, wave crests are formed on both sides of the main body 10, and wave troughs are formed in cooperation with the first contact portion 30 and the second contact portion 33 on both sides of the main body 10. Similarly, when cutting the double-sided tape 11, the loss of the tape can also be reduced, and the production yield can be improved. At the same time, compared with the straight strip structure in the prior art, the wavy first contact portion 30 has a larger bonding area and a better bonding effect.
