Description

Technical Field

[0001] This invention belongs to the field of self-adhesive technology, and in particular to a self-adhesive for test tubes. Background Technology

[0002] In laboratory glass test tube labeling scenarios, ordinary waterproof self-adhesive labels are often used to distinguish test tubes; however, when the test tubes contain other liquids and the labels need to be changed and re-distinguished, the adhesive residue left after the traditional waterproof self-adhesive labels are applied is difficult to clean completely, which will hinder subsequent labeling operations. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a self-adhesive label for test tubes.

[0004] The objective of this utility model can be achieved through the following technical solutions: A self-adhesive label for test tubes includes: a face material layer, a pressure-sensitive adhesive layer disposed on the lower surface of the face material layer, and a release liner layer adhered to the lower surface of the pressure-sensitive adhesive layer. The face material layer includes a plurality of parallel service layers. Each service layer has a handle portion at its end. The pressure-sensitive adhesive layer of the handle portion is laminated with a film layer. The film layer is separated from the release liner layer.

[0005] In the aforementioned self-adhesive labels for test tubes, there are indentation lines between adjacent layers, and the depth of the indentation lines is at least 4 / 5 of the thickness of the surface layer.

[0006] In the aforementioned self-adhesive labels for test tubes, there are dotted tear lines between adjacent hand grips.

[0007] In the aforementioned self-adhesive label for test tubes, the face layer is a low-temperature resistant polypropylene film, and the thickness of the face layer is 0.06 mm to 0.1 mm.

[0008] In the aforementioned self-adhesive label for test tubes, the length of the handle portion is 2 mm to 3 mm along the length direction of the application layer.

[0009] In the aforementioned self-adhesive labels for test tubes, the upper surface of the application layer has a reserved area of ​​not less than 2 cm². 2 The writing area has a roughened surface.

[0010] In the aforementioned self-adhesive label for test tubes, the writing area is locally thickened and roughened, with a surface roughness Ra value reaching 0.8-1.6 μm.

[0011] Compared with the prior art, this application has the following advantages: Traditional self-adhesive labels require complete peeling when changing, which is quite troublesome. You need to peel the label off gradually from one side. The handheld part has a composite film layer, which is non-sticky and easy to grip, allowing you to directly and conveniently peel the working layer off the test tube. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0014] like Figures 1 to 3 As shown, a self-adhesive label for a test tube 100 includes: a face material layer 2, a pressure-sensitive adhesive layer 3 disposed on the lower surface of the face material layer 2, and a release liner layer 4 adhered to the lower surface of the pressure-sensitive adhesive layer 3. The face material layer 2 includes a plurality of parallel service layers 21. A handle portion 22 is provided at the end of the service layer 21. A film layer 23 is laminated to the pressure-sensitive adhesive layer 3 of the handle portion 22. The film layer 23 is separated from the release liner layer 4.

[0015] In this application, the release liner layer 4 is peeled off, and the pressure-sensitive adhesive layer 3 is used to adhere the self-adhesive label to the surface of the test tube 100. Multiple usable layers 21 can be removed and used individually, or multiple usable layers 21 can be removed and used together side-by-side, serving a common labeling function. When the test tube 100 is refilled with liquid and the label needs to be updated, the handle 22 at the end of the face material layer 2 is pinched. The pressure-sensitive adhesive layer 3 in this area is combined with a thin film layer 23, leaving no sticky residue and separating from the release liner layer 4. The outermost usable layer 21 can then be easily and completely peeled off, and a new self-adhesive label can be applied.

[0016] Traditional self-adhesive labels require complete peeling when replacing, which is quite troublesome. The self-adhesive needs to be peeled off gradually from one side. The handheld part 22 has a composite film layer 23 that is non-sticky and easy to grip, allowing the working layer 21 to be peeled off directly and conveniently from the test tube 100.

[0017] Specifically, there is an indentation line 24 between adjacent use layers 21, and the depth of the indentation line 24 is at least 4 / 5 of the thickness of the surface layer 2.

[0018] The indentation lines 24 set between adjacent use layers 21 can form a physical separation guide structure. Combined with the depth design of ≥4 / 5 of the thickness of the surface layer 2, it can be easily peeled off the outermost use layer 21. The peeling only acts on the target layer and will not cause the lower spare use layer 21 to lift or stick, ensuring the accuracy of the peeling operation.

[0019] Specifically, there are dotted tear lines 25 between adjacent hand-held parts 22.

[0020] The tear lines 25 between adjacent hand-held parts 22 can divide the entire sheet of self-adhesive labels into several independent test tube 100 labeling units. Experimenters can tear off the corresponding units as needed according to the number of test tubes 100 without cutting the entire sheet of labels. This is especially suitable for scenarios where multiple specifications and batches of test tubes 100 are labeled at the same time, improving operational flexibility.

[0021] Specifically, the face material layer 2 is a low-temperature resistant polypropylene film, and the thickness of the face material layer 2 is 0.06 mm to 0.1 mm.

[0022] Specifically, the length of the handle portion 22 is 2mm to 3mm along the length direction of the use layer 21.

[0023] The length of the handle 22 is controlled between 2mm and 3mm, which ensures the force-bearing area for finger pinching without causing the handle 22 to exceed the circumference of the test tube 100 due to excessive length. At the same time, since the outer surface of the test tube 100 is arc-shaped, after the use layer 21 is attached to the surface of the test tube 100, the handle 22 is also attached to the outer surface of the test tube 100. Since its attachment is only arc-shaped, the distance between the handle 22 and the surface of the test tube 100 is reduced.

[0024] Specifically, a space of not less than 2 cm² is reserved on the upper surface of layer 21. 2 The writing area has a roughened surface.

[0025] Specifically, the writing area is locally thickened and roughened, with a surface roughness Ra value of 0.8-1.6μm.

[0026] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0027] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
