Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bottomless paper thermal labels, and particularly to a bottomless paper thermal label. Background Technique
[0002] Thermal paper refers to information recording paper coated with a color-forming material that self-develops under thermal signal excitation. Thermal paper has developed rapidly with the popularization of fax machines worldwide. With the development of electronic communication, thermal paper is not only popular in individual families in the form of fax paper, but also appears in various fields such as commerce, supermarkets, banks, hospitals, and airports. Its uses are becoming increasingly widespread, the varieties are increasing day by day, and the scope of use is getting wider and wider. With the improvement of the requirements for the use of thermal paper, bottomless paper thermal self-adhesive labels have emerged, which have good water resistance, oil resistance, ethanol resistance and other properties.
[0003] For example, the bottomless paper thermal self-adhesive label is disclosed in the utility model with the application number 201910877430.4. By setting a thermal printing color-forming layer, a waterproof layer and a water-based silicone oil layer on the base paper layer, while ensuring the waterproof, fireproof, anti-static, wear-resistant and writable properties of the thermal paper, the production cost is reduced. Among them, by using a water-based silicone oil layer with a rough upper surface, the smooth writing on the thermal paper is ensured.
[0004] The similar applications currently still have deficiencies:
[0005] This kind of bottomless paper thermal self-adhesive label is convenient for smooth writing on thermal paper, but it has certain limitations for the items to be pasted. Especially, this kind of bottomless paper thermal self-adhesive label can only be pasted on a flat surface. When pasting an item with a certain curvature, the corners will bulge during pasting, and impurities will enter over time, reducing the adhesiveness and even causing detachment.
[0006] Therefore, a bottomless paper thermal label is designed to optimize the above problems. Content of the Utility Model
[0007] The main purpose of the utility model is to provide a bottomless paper thermal label to solve the related technical problems raised in the above background technique.
[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0009] A bottomless paper thermal label, comprising a base layer, a paste layer is fixed on the top of the base layer, a reinforcement layer is fixed on the top of the paste layer, a thermal layer is fixed on the top of the reinforcement layer, a writing layer is arranged at one end of the top of the thermal layer, folding grooves are provided on both sides of the writing layer, the reinforcement layer, the thermal layer, the paste layer and the base layer, an upper protective layer is arranged between the thermal layer and the writing layer, grooves one are provided at both ends of the upper protective layer, a lower protective layer is arranged between the thermal layer and the reinforcement layer, and grooves two are provided at both ends of the lower protective layer.
[0010] Preferably: Non-sticking sheets are fixed on both sides of the paste layer, and protective strips are fixed on the bottom of the non-sticking sheets and on the side close to the paste layer.
[0011] Preferably: An installation groove is provided on the thermal layer, and a sensitive indication layer is installed inside the installation groove.
[0012] Preferably: Anti-slip layers are arranged on the bottom and top of the non-sticking sheets, and anti-slip particles are arranged on the anti-slip layers.
[0013] Preferably: The number of the upper protective layers is set to two groups, and fiber filaments are arranged inside the two groups of upper protective layers.
[0014] Preferably: An adhesive is arranged at the bottom of the sensitive indication layer, and the size of the sensitive indication layer matches the size of the installation groove.
[0015] The beneficial effects of the present utility model are:
[0016] The bottomless paper thermal label provided by the present utility model, through the combined use of the base layer, the paste layer, the reinforcement layer, the writing layer, the folding grooves, the upper protective layer, the groove one, the lower protective layer, the groove two and the thermal layer, can fold the whole base layer at the folding grooves, so that the base layer completely fits the outer surface of the object to be pasted, reducing problems such as arching caused by uneven pasting affecting the pasting viscosity and easy falling off, thereby improving the application range of the bottomless paper thermal label;
[0017] Through the combined use of the non-sticking sheets and the protective strips, when it is necessary to tear off the paste layer, its base layer and the whole thermal layer, the user first pinches the non-sticking sheets with fingers, and then tears along the dividing point between the paste layer and the paste layer, and the whole paste layer can be removed, and the fingers will not contaminate the base layer and affect the adhesiveness. Similarly, when the pasting position is incorrect and needs to be changed, pinch the non-sticking sheets again to tear off the whole paste layer, and the protective strips increase the degree of fit with the object, reducing the pollution of the bonding part by dust and impurities;
[0018] By using the cooperation of the installation groove and the sensitive indication layer, after the adhesive layer is pasted on an article through the base layer, the sensitive indication layer exposed to the air detects the placement environment of the article. According to needs, the material of the sensitive indication layer can be adjusted. The sensitive indication layer can be changed according to the humidity, temperature or acidity of the storage environment of the article as needed. When the storage environment of the article is too humid or other situations, the sensitive indication layer changes color, and the placement position of the article can be adjusted. It is possible to quickly determine whether the environment is suitable for storing such articles based on the color of the sensitive indication layer, which is beneficial to the accurate storage of the marked articles, thereby improving the practicality of this bottomless paper thermal label.

According to the curvature of the object, first position and paste the middle position of the base layer 1 at the center position of the object, and then roll and flatten the thermosensitive layer 14 in all directions in turn, so that the base layer 1 can be pasted onto the object over a large area. At the same time, fold the folding groove 5 according to the curvature, so that the two corners formed by the base layer 1 divided by the folding groove 5 and the adhesive layer 2 and the thermosensitive layer 14 are folded and adhered to each other. Thus, the pasting of the base layer 1 to the object is completed. When it is necessary to tear off the entire adhesive layer 2, its base layer 1, and the thermosensitive layer 14, the user first pinches the non-sticking piece 10 with a finger, and then tears along the dividing point between the adhesive layer 2 and the adhesive layer 2, and the entire adhesive layer 2 can be removed, and the finger will not contaminate the base layer 1 and affect the adhesiveness.
