Description

Technical Field

[0001] This utility model relates to the field of adhesive products technology, and in particular to a pressure-sensitive adhesive product. Background Technology

[0002] Pressure-sensitive adhesives are a class of materials that bond by applying only light pressure, without the need for solvents, moisture, or heating. These products are widely used in homes, offices, and industrial settings due to their convenience and efficiency. For example, in industrial applications, fabric strips are used to wrap wire harnesses; these fabric strips are a type of pressure-sensitive adhesive.

[0003] In the use of existing pressure-sensitive adhesive products, operators need to peel off the adhesive strips one by one from the base film. Because the adhesive strips are tightly adhered to the base film, peeling off the adhesive strips takes a lot of time, resulting in low work efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a pressure-sensitive adhesive product, which aims to solve the problem that the adhesive strip is difficult to peel off from the bottom film in current pressure-sensitive adhesive products.

[0005] To achieve the above objectives, this utility model proposes a pressure-sensitive adhesive product, including a base film and a plurality of adhesive strip groups adhered to the base film. The plurality of adhesive strip groups are arranged in contact with each other along a first direction to form at least one contact line between the plurality of adhesive strip groups. Each adhesive strip group includes a plurality of adhesive strip units arranged along a second direction. The base film includes a plurality of fixed regions arranged alternately along the first direction and at least one detachable partition region. The partition region is arranged corresponding to the contact line so that after the partition region is removed, the ends of the plurality of adhesive strip units located on both sides of the contact line are exposed to the outside.

[0006] In one embodiment, the base film is provided with a plurality of indentation groups arranged at intervals along a first direction. The plurality of indentation groups are provided corresponding to a plurality of contact lines. Each indentation group includes two indentations arranged at intervals along the first direction. The two indentations are respectively located on both sides of the contact line to divide the separation area.

[0007] In one embodiment, the dimension of the fixed region in the first direction is larger than the dimension of the dividing region in the first direction.

[0008] In one embodiment, the size of the dividing region in the first direction is A, and the distance from the contact line to the nearest indentation is B, satisfying: 0.4A≤B≤0.5A.

[0009] In one embodiment, the minimum distance from the contact line to the indentation is greater than the dimension of the adhesive strip unit in the second direction.

[0010] In one embodiment, the indentation includes a straight indentation or a serrated indentation.

[0011] In one embodiment, the bottom film further includes a disassembly portion that protrudes from one side of the partition region in a second direction.

[0012] In one embodiment, the disassembly section is provided with an indicator mark for indicating the removal of the dividing area.

[0013] In one embodiment, two adhesive strips are provided, and one dividing area is provided.

[0014] In one embodiment, the pressure-sensitive adhesive product includes a strip of velvet.

[0015] The technical solution of this utility model provides a plurality of fixed areas arranged alternately in a first direction and at least one detachable partition area on the base film. This allows the ends of the adhesive strip units on both sides of the contact line to be exposed to the outside after the partition area is removed, and the two adjacent adhesive strip groups to be separated. This makes it easier for the operator to tear off the adhesive strip units, thereby reducing the difficulty of tearing the adhesive strip units off the base film and improving work efficiency.

[0025] Pressure-sensitive adhesives are a class of materials that bond by applying only light pressure, without the need for solvents, moisture, or heating. These products are widely used in homes, offices, and industrial settings due to their convenience and efficiency. For example, in industrial applications, fabric strips are used to wrap wire harnesses; these fabric strips are a type of pressure-sensitive adhesive.

[0026] In the use of existing pressure-sensitive adhesive products, operators need to peel off the adhesive strips one by one from the base film. Because the adhesive strips are tightly adhered to the base film, peeling off the adhesive strips takes a lot of time, resulting in low work efficiency.

[0027] The main purpose of this utility model is to propose a pressure-sensitive adhesive product, which aims to solve the problem that the adhesive strip is difficult to peel off from the bottom film in current pressure-sensitive adhesive products.

[0028] Please see Figure 1 and Figure 2This utility model proposes a pressure-sensitive adhesive product 1000, including a base film 1 and a plurality of adhesive strip groups 2 adhered to the base film 1. The plurality of adhesive strip groups 2 are arranged in contact with each other along a first direction to form at least one contact line 22 between the plurality of adhesive strip groups 2. Each adhesive strip group 2 includes a plurality of adhesive strip units 21 arranged along a second direction. The base film 1 includes a plurality of fixed regions 11 arranged alternately along the first direction and at least one detachable partition region 12. The partition region 12 is provided corresponding to the contact line 22 so that after the partition region 12 is removed, the ends of the plurality of adhesive strip units 21 located on both sides of the contact line 22 are exposed to the outside.

[0029] The technical solution of this utility model provides a plurality of fixed areas 11 arranged alternately in a first direction and at least one detachable partition area 12 on the base film 1. After the partition area 12 is removed, the ends of the adhesive strip units 21 on both sides of the contact line 22 are exposed to the outside, and two adjacent adhesive strip groups 2 are separated. This makes it easier for the operator to tear off the adhesive strip units 21, thereby reducing the difficulty of tearing the adhesive strip units 21 off the base film 1 and improving work efficiency.

[0030] It should be noted that this solution does not limit the specific implementation of the fixed area 11 and the detachable area on the bottom film 1. In a preferred embodiment provided in this solution, please refer to... Figure 1 and Figure 2 The base film 1 is provided with a plurality of indentation groups 13 arranged at intervals along a first direction. Each indentation group 13 corresponds to a plurality of contact lines 22. Each indentation group 13 includes two indentations 131 spaced apart along the first direction, with the two indentations 131 located on either side of the contact line 22 to define the separating area 12. This arrangement, by dividing the fixed area 11 and the separating area 12 in the form of indentations 131, simplifies the process and facilitates manufacturing. Furthermore, the separating area 12 defined by the indentations 131 is easily removed, thereby improving production efficiency.

[0031] In another embodiment of this solution, the fixed area 11 is made of a different material than the separating area 12 and they are spaced apart. The separating area 12 serves only as a bridge connecting two adjacent adhesive strip groups 2, preventing adhesive strip contamination and facilitating separation from the adhesive strip unit 21. With this configuration, the separating area 12 only needs to be directly separated from the adhesive strip, without needing to consider separation from the fixed area 11, further improving work efficiency.

[0032] It should also be noted that this solution does not limit the specific number of adhesive strip groups 2. In specific implementation, setting more adhesive strip groups 2 can facilitate the mass production of pressure-sensitive adhesive products 1000 and reduce material waste during the production process. Setting fewer adhesive strip groups 2 can speed up the tearing efficiency of adhesive strip units 21. For example, in a preferred embodiment, there are two adhesive strip groups 2 and one dividing area 12. With this setting, only one dividing area 12 needs to be removed to obtain two processed adhesive strip groups 2, which greatly improves work efficiency.

[0033] It is worth mentioning that, in a preferred embodiment, the pressure-sensitive adhesive product 1000 is a velvet strip. In the industrial field, velvet strips are needed to wrap wire harnesses. However, compared to other pressure-sensitive adhesive products, the velvet strip has a stronger adhesion to the base film 1, making it difficult to separate and potentially damaging the base film 1 during the tearing process. This makes it difficult for other adhesive strips to have a good gripping point for tearing. By applying this solution to the velvet strip, the tearing efficiency of the velvet strip can be greatly improved, thereby helping operators to complete the winding of the wire harness more quickly and improving work efficiency.

[0034] Furthermore, the dimension of the fixed area 11 in the first direction is larger than the dimension of the dividing area 12 in the first direction. With this configuration, after the dividing area 12 is removed, the exposed dimension of the adhesive strip unit 21 on the pasting side will be smaller than the non-exposed dimension, thereby ensuring the stability of the overall structure after removal and preventing the end of the adhesive strip unit 21 from shaking excessively and becoming contaminated.

[0035] It should be noted that the size of the dividing area 12 is not necessarily better the smaller it is. In one embodiment, the minimum distance from the contact line 22 to the indentation 131 is greater than the size of the adhesive strip unit 21 in the second direction. With this configuration, the longer side of any adhesive strip unit 21 exposed on the adhesive side can be guaranteed in the first direction, which makes it easier for the operator to tear off the adhesive strip unit 21 extending in the first direction, thereby indirectly improving work efficiency.

[0036] Furthermore, the dimension of the separating area 12 in the first direction is A, and the distance from the contact line 22 to the nearest indentation 131 is B, satisfying: 0.4A≤B≤0.5A. This setting ensures that the contact line 22 is located in a relatively central position in the separating area 12 in the first direction, thereby ensuring that the dimensions of the exposed portions on both sides of the contact line 22 are approximately consistent, facilitating subsequent tearing.

[0037] Furthermore, the indentation 131 is configured as a straight indentation or a serrated indentation. Among them, the straight indentation is easier to process and leaves a more uniform tear, while the serrated indentation is easier to tear and has a lower probability of deviating from the tear trajectory, thus resulting in a higher tearing success rate.

[0038] In one embodiment provided in this solution, please refer to Figure 1 The bottom film 1 also includes a disassembly part 14, which protrudes from one side of the dividing area 12 in the second direction. This configuration allows the dividing area 12 to be removed by pulling the disassembly part 14 before tearing off the adhesive strip unit 21, thus providing the operator with a point of leverage.

[0039] It is worth mentioning that the disassembly section 14 is equipped with an indicator to indicate the removal of the partition area 12. This design makes the structure more user-friendly, providing operational guidance and indirectly improving work efficiency.

[0040] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
