Description

Technical Field

[0001] This utility model relates to the field of foam tape technology, and in particular to a tear-away foam tape. Background Technology

[0002] Foam tape is a type of adhesive tape made by coating pressure-sensitive adhesive onto foam as the base material. Additionally, release paper can be applied over the pressure-sensitive adhesive for anti-sticking protection. Based on the properties of foam and pressure-sensitive adhesive, foam tape provides bonding, sealing, and shock absorption, and is widely used in product bonding and packaging.

[0003] Foam tape is usually sold in rolls, requiring unwinding and cutting before use. To improve shock absorption, the foam substrate has a certain thickness, increasing the difficulty of tearing by hand and often requiring a cutting tool, which increases the risk of accidents and reduces ease of use and efficiency. Furthermore, the release liner also adds to the difficulty of tearing by hand and needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a hand-tearable foam tape that is easy to tear by hand, thus improving ease of use and efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution: A tear-resistant foam tape includes: a strip of foam and a pressure-sensitive adhesive layer. A first tear groove is recessed on one side of the strip of foam along its length, extending along the thickness direction of the strip of foam. A second tear groove is recessed on the side of the strip of foam opposite to the first tear groove along its length, and the first and second tear grooves are staggered along the length of the strip of foam. The pressure-sensitive adhesive layer is disposed above the strip of foam and covers the area on the top surface of the strip of foam except for the first and second tear grooves. A third tear groove corresponding to each of the first tear grooves and a fourth tear groove corresponding to each of the second tear grooves are recessed on the bottom surface of the strip of foam.

[0006] Release paper is disposed above the pressure-sensitive adhesive layer.

[0007] The release paper has a fifth tear groove on its edge that corresponds one-to-one with the first tear groove.

[0008] The release paper has first waist holes spaced apart along the width direction at positions corresponding to the fifth tear groove.

[0009] The release paper has a sixth tear groove on its edge that corresponds one-to-one with the second tear groove.

[0010] The release paper has second waist holes spaced apart along the width direction at positions corresponding to the sixth tear groove.

[0011] The first, second, third, and fourth tear grooves are V-shaped grooves.

[0012] The third and fourth tear grooves extend along the width of the strip foam.

[0013] The beneficial effects of this utility model are as follows: A hand-tearable foam tape is specially designed with a first tear groove and a second tear groove. The strip of foam can be torn and cut by hand from a certain first tear groove or second tear groove as needed. The third tear groove and the fourth tear groove are used to further reduce the difficulty of hand tearing and improve the flatness and aesthetics of the cut. The fifth tear groove and the sixth tear groove can also reduce the difficulty of hand tearing the release paper, so that the release paper can be torn and cut by hand simultaneously with the strip of foam, improving the convenience and efficiency of use. No cutting tool is needed, and the operation is safer. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 Top view of the strip-shaped foam; Figure 3 yes Figure 1 Top view of the release liner. Detailed Implementation

[0015] The following is combined with Figures 1-3 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The tear-off foam tape shown includes: a strip of foam 1 and a pressure-sensitive adhesive layer 2, such as... Figure 2 As shown, a first tear groove 13 is recessed on one side of the strip foam 1 along its length direction. The first tear groove 13 extends along the thickness direction of the strip foam 1. A second tear groove 14 is recessed on the side of the strip foam 1 opposite to the first tear groove 13 along its length direction. The first tear groove 13 and the second tear groove 14 are staggered along the length direction of the strip foam 1, with an interval of 1 cm between them, which facilitates the cutting of the strip foam 1 to a fixed length.

[0017] The strip foam 1 can be manually torn from either the first tear groove 13 or the second tear groove 14 as needed, reducing the difficulty of the manual tearing operation. In addition, the first tear groove 13 and the second tear groove 14 are staggered on both sides, reducing the number of tear grooves on one side, which helps to improve the structural stability of the strip foam 1 during use after cutting.

[0018] The bottom surface of the strip foam 1 is recessed with a third tear groove 11 corresponding to the first tear groove 13 and a fourth tear groove 12 corresponding to the second tear groove 14. In this embodiment, the first tear groove 13, the second tear groove 14, the third tear groove 11 and the fourth tear groove 12 are V-shaped grooves to facilitate hand tearing.

[0019] like Figure 1 As shown, the third tear groove 11 and the fourth tear groove 12 extend along the width direction of the strip foam 1. The third tear groove 11 and the fourth tear groove 12 further reduce the difficulty of tearing the strip foam 1 by hand. During the tearing process, the broken edge is guided to extend along the width direction of the strip foam 1, thereby improving the flatness and aesthetics of the broken edge.

[0020] By placing the pressure-sensitive adhesive layer 2 above the strip foam 1 and covering the area on the top surface of the strip foam 1 except for the first tear groove 13 and the second tear groove 14, the consumption and cost of the pressure-sensitive adhesive layer 2 are reduced during the production process.

[0021] like Figure 1 As shown, a release paper 3 is disposed above the pressure-sensitive adhesive layer 2, providing anti-stick protection for the pressure-sensitive adhesive layer 2. Figure 3 As shown, the release paper 3 has a fifth tear groove 31 on its edge, corresponding one-to-one with the first tear groove 13, facilitating simultaneous tearing of the strip foam 1 and the release paper 3. In this embodiment, the release paper 3 has first waist holes 33 spaced along its width at positions corresponding to the fifth tear groove 31, reducing the resistance when tearing the release paper 3 from the fifth tear groove 31, making the overall operation more effortless.

[0022] In this embodiment, the release paper 3 has a sixth tear groove 32 on its edge that corresponds one-to-one with the second tear groove 14, such as... Figure 3 As shown, this facilitates hand tearing of the strip foam 1 and release paper 3 from the second tear groove 14 and the sixth tear groove 32. Similarly, the release paper 3 is provided with second waist holes 34 at intervals along the width direction corresponding to the position of the sixth tear groove 32, which reduces the resistance when hand tearing the release paper 3 starting from the sixth tear groove 32.

[0023] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
