[0021] Reference Figures 1 to 4According to a first aspect of the present invention, a test tube 300 tape includes a base paper 100, the base paper 100 having a plurality of unit portions 110, an easy-tear structure 120 provided between each unit portion 110, and an adhesive layer 200 provided on one side of each unit portion 110. The adhesive layer 200 has a first through hole 210 for avoiding the opening of the test tube 300. The adhesive layer 200 includes an adhesive layer 220 and a release layer 230. The adhesive layer 220 is bonded to the unit portion 110, and the release layer 230 covers the side of the adhesive layer 220 away from the unit portion 110. When sealing the opening of test tube 300, a unit 110 can be torn off through the tear-off structure 120, and then the release layer 230 of the unit 110 can be torn off from the adhesive layer 220. Then, the first through hole 210 can be aligned with the opening of test tube 300 so that the opening of test tube 300 avoids the adhesive layer 220. Then, the adhesive layer 220 can be bonded to the side wall of test tube 300 to achieve sealing. The operation is convenient, and the tape has low usage cost and is easy to store. Specifically, the shape of the base paper 100 is not limited here. Each unit 110 is an adhesive piece for sealing the opening of the test tube 300. The unit parts 110 are connected by an easy-tear structure 120. The specific structure of the easy-tear structure 120 is not described in detail here. The user can tear off a unit part 110 through the easy-tear structure 120. The first through hole 210 on the adhesive layer 200 of the unit part 110 can be set according to the size of the opening of the test tube 300. Through the first through hole 210, the inside of the test tube 300 can only contact the base paper 100 and not the adhesive layer 220 to avoid contamination of the test tube 300. The release layer 230 can be a release paper. After the release paper is torn off, the adhesive layer 220 can be exposed. The adhesive layer 220 can be made by applying glue. Through the adhesive layer 220, the base paper 100 around the first through hole 210 can be bonded to the outer wall of the test tube 300 to achieve sealing of the opening of the test tube 300.

[0022] It is conceivable that during the manufacturing of the adhesive layer 200, the sandwich adhesive tape can first be punched with the first through-hole 210. The layered structure of the sandwich adhesive tape consists of release paper, adhesive layer 220, and release paper in sequence. The adhesive tape with the first through-hole 210 punched can have one side of the release paper peeled off and the adhesive tape pasted onto the base paper 100.

[0023] Reference Figure 1 In some embodiments of this utility model, the base paper 100 is configured as a rectangular strip structure, the unit portions 110 are arranged sequentially along the length direction of the base paper 100, and the tear-resistant structure 120 extends along the width direction of the base paper 100. Specifically, the unit portions 110 can be square, and the base paper 100 can be configured as a rectangular strip of adhesive tape formed by arranging the unit portions 110 one by one. Each unit portion 110 has a tear-resistant structure 120 between it. Each time it is used, the outermost unit portion 110 can be torn off, which is easy to operate.

[0024] Reference Figure 2 In some embodiments of this utility model, the base paper 100 includes a waterproof membrane layer 130 and a paper layer 140, with the adhesive layer 200 connected to the paper layer 140. Specifically, the waterproof membrane layer 130 can be made of PET material, which can prevent external liquids from seeping into the test tube 300 or prevent liquids inside the test tube 300 from seeping out, while the paper layer 140 can be fully bonded to the adhesive layer 220 to prevent the adhesive layer 200 from falling off.

[0025] Reference Figure 2 In some embodiments of this invention, the base paper 100 further includes an outer film layer 150, which is disposed on the side of the waterproof film layer 130 away from the paper layer 140. The outer surface of the outer film layer 150 is provided with friction textures to increase friction. Specifically, the outer film layer 150 can be made of materials such as PP, PE, and PET, and during the manufacturing process, uneven friction textures can be set on the film surface. When the operator is handling the outer film layer 150, the friction textures on the outer film layer 150 can increase friction, significantly increasing the friction between the fingers or gloves and the test tube 300, preventing slippage during operation and improving safety.

[0026] It is conceivable that the outer membrane layer 150 can be omitted, and an uneven friction texture can be directly set on the outer surface of the waterproof membrane layer 130.

[0027] In some embodiments of this invention, the base paper 100 further includes a labeling layer disposed on the side of the waterproof membrane layer 130 away from the paper layer 140. Specifically, the labeling layer can be distinguished by color to classify the tape by color. For example, different colors can represent different items, different batches, or different processing conditions, making it easy to see and distinguish.

[0028] Reference Figure 3 In some embodiments of this utility model, the base paper 100 is a square-shaped sheet, and the unit portions 110 are arranged in an array along the length and width directions of the base paper 100. An easy-tear structure 120 is provided between adjacent unit portions 110. Specifically, the unit portions 110 can also be arrayed on a sheet such as a page, and the easy-tear structures 120 are arranged longitudinally and transversely between the unit portions 110. When in use, the unit portions 110 can be torn off one by one, which is convenient for operation and storage.

[0029] Reference Figure 1 and Figure 3In some embodiments of this utility model, the release layer 230 is provided with a positioning portion 231 extending out of the adhesive layer 220. Specifically, the release layer 230 can be directly torn open by operating the positioning portion 231 without having to pry it open along the edge of the release layer 230, which can further improve the convenience of operation. The positioning portion 231 can be a protruding strip, and its specific shape is not limited here.

[0030] In some embodiments of this invention, the adhesive layer 220 is a pressure-sensitive adhesive layer. Specifically, the pressure-sensitive adhesive layer can be a high-performance acrylic pressure-sensitive adhesive, which can ensure durable adhesion at room temperature or low temperature and leave no residue after removal.

[0031] In some embodiments of this utility model, the easy-tear structure 120 is configured as an easy-tear line composed of multiple spaced strip holes, which is relatively easy to manufacture.

[0032] In some embodiments of this invention, a winding seat is also included, around which the base paper 100 is wound. Specifically, the winding seat can wind the strip of base paper 100 into a roll for easy storage. It can also be used like ordinary tape, which is quite convenient.

[0033] Reference Figure 5 It should be noted that the diameter of the first through hole 210 can be set to be larger, and multiple annular adhesive rings 400 of different diameters can be set inside the first through hole 210. Each adhesive ring 400 is nested inside and outside the other. The adhesive ring 400 can include an adhesive layer 200, a release layer 230, and a waterproof layer. When the release layer 230 is not removed from the adhesive rings 400, the first through hole 210 is the maximum diameter suitable for the opening of the test tube 300. After the release layer 230 is removed from the outer adhesive rings 400, the actual diameter of the first through hole 210 can be reduced to accommodate test tubes 300 of different diameters.
