Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical labeling technology, and in particular to a novel high-adhesion, wrinkle-resistant pharmaceutical label. Background Technology

[0002] Pharmaceutical-specific labels are special labels used specifically in the pharmaceutical field to identify information about drugs, medical devices, and other related products. They must meet the stringent requirements of the pharmaceutical industry regarding safety, stability, and information accuracy. They are a crucial carrier for ensuring the accurate and standardized transmission of pharmaceutical product information. Their applications are wide-ranging, covering various types of pharmaceutical packaging, such as glass bottles, plastic bottles, aluminum-plastic blister packs, and cardboard boxes, as well as the surfaces of various medical devices such as infusion sets, syringes, scalpels, and monitors. In these scenarios, pharmaceutical-specific labels play an irreplaceable role.

[0003] Currently, existing labels have a simple adhesive structure design, mostly relying on a single adhesive layer for adhesion, lacking auxiliary structures to enhance adhesion, resulting in insufficient overall adhesion. During transportation, bumps, changes in temperature and humidity during storage, or even slight contact during daily use, labels are prone to detachment, especially at the edges, which are easily separated from the adhered surface and peel off. This risks blurring or losing key information on the label, severely affecting the accuracy of information reading. Therefore, a novel high-adhesion, wrinkle-resistant pharmaceutical label is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel high-adhesion, wrinkle-resistant medical label, which aims to improve the problem that existing labels have a simple adhesive structure design, mostly relying on a single adhesive layer for adhesion, lacking auxiliary structures to enhance adhesion, resulting in insufficient overall adhesion.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel high-adhesion anti-wrinkle pharmaceutical label, comprising a label body, wherein a rubber base adhesive is provided around the bottom of the label body, multiple micro-pits are provided at the bottom of the label body, multiple micro-capsules are provided at the bottom of the label body, and the label body is divided into a surface layer, a middle layer, an elastic buffer layer and an adhesive layer from top to bottom.

[0006] As a further description of the above technical solution:

[0007] The surface layer is made of biaxially oriented polypropylene film.

[0008] As a further description of the above technical solution:

[0009] The intermediate layer is made of a thin polyester film.

[0010] As a further description of the above technical solution:

[0011] The elastic buffer layer is made of foamed acrylic pressure-sensitive adhesive.

[0012] As a further description of the above technical solution:

[0013] The adhesive layer is made of medical-grade silicone pressure-sensitive adhesive.

[0014] As a further description of the above technical solution:

[0015] The micro-dimples and micro-capsules are evenly distributed on the bottom of the label body.

[0016] As a further description of the above technical solution:

[0017] The rubber-based adhesive is a mixture of natural rubber, terpene resin, and phthalates.

[0018] As a further description of the above technical solution:

[0019] The microcapsules are filled with modified polyvinyl alcohol.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the label body achieves high adhesion through the synergistic effect of multiple structures. The adhesive layer, as the main adhesive structure, provides initial adhesion, ensuring that the label can be initially and firmly adhered; the microcapsules filled with modified polyvinyl alcohol release the modified polyvinyl alcohol after being ruptured under pressure, further enhancing the overall adhesion; the rubber-based adhesive around the bottom provides additional adhesive support for the edges, effectively reducing edge lifting, enabling the label to adhere tightly to the surface being adhered in pharmaceutical applications, significantly reducing the risk of detachment, and ensuring that the label information is always clearly identifiable;

[0022] 2. In this utility model, the layered structure plays a key role. The middle layer provides sufficient structural strength, enhances the overall stiffness of the label, and reduces wrinkles caused by external forces; the elastic buffer layer can buffer external impacts and pressures, maintain the stability of the label shape, and prevent deformation or wrinkles due to collisions or squeezing, ensuring that the label appearance is flat and the information display is not affected.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3 This utility model provides an embodiment of a novel high-adhesion, wrinkle-resistant medical label, comprising a label body 1. Rubber-based adhesive 2 is provided around the bottom perimeter of the label body 1. The rubber-based adhesive 2 provides additional adhesive support at the edges of the label body 1, enhancing the adhesion between the label body 1 and the edge of the surface to be pasted, and reducing edge lifting. Multiple micro-dimples 3 are formed at the bottom of the label body 1. These micro-dimples 3 can accommodate some air during the pasting process, preventing air bubbles from forming between the label body 1 and the surface to be pasted, ensuring a smooth paste. Multiple micro-capsules 4 are provided at the bottom of the label body 1. When the label body 1 is subjected to external pressure, the micro-capsules 4 rupture, releasing internal modified polyvinyl alcohol to further enhance the adhesion between the label body 1 and the surface to be pasted. The label body 1 is divided into a top layer 5, a middle layer 6, an elastic buffer layer 7, and an adhesive layer 8 from top to bottom. This layered structure allows the label body 1 to integrate the performance advantages of each layer, achieving high adhesion and wrinkle resistance.

[0030] Reference Figures 1-3 The surface layer 5 is made of biaxially oriented polypropylene film. As the outermost layer of the label body 1, the surface layer 5 protects the internal structure of the label body 1 and resists the wear and erosion of the label body 1 by the external environment. At the same time, it facilitates the printing of information on its surface.

[0031] Reference Figures 1-3 The intermediate layer 6 is made of thin polyester film. The intermediate layer 6 is located between the surface layer 5 and the elastic buffer layer 7, providing a certain structural strength for the label body 1, enhancing the overall stiffness of the label body 1, and reducing wrinkles caused by external forces.

[0032] Reference Figures 1-3The elastic buffer layer 7 is made of foamed acrylic pressure-sensitive adhesive. The elastic buffer layer 7 can buffer the impact and pressure of the external force on the label body 1, reduce the wrinkling or deformation of the label body 1 caused by external pressure, and maintain the shape stability of the label body 1.

[0033] Reference Figures 1-3 The adhesive layer 8 is made of medical-grade silicone pressure-sensitive adhesive. The adhesive layer 8 is the main structure for the label body 1 to achieve the pasting function, which enables the label body 1 to be firmly pasted on the medical related pasting surface, ensuring that the label is not easy to fall off during use.

[0034] Reference Figures 1-3 Micro-dimples 3 and micro-capsules 4 are evenly distributed on the bottom of the label body 1. The even distribution of micro-dimples 3 ensures that air can be effectively contained in all positions on the bottom of the label body 1. The even distribution of micro-capsules 4 enables all areas on the bottom of the label body 1 to release substances through their rupture to evenly enhance adhesion, thereby ensuring the consistency of the overall adhesive effect of the label body 1.

[0035] Reference Figures 1-3 The rubber-based adhesive 2 is a mixture of natural rubber, terpene resin and phthalates. The mixed composition of the rubber-based adhesive 2 can better adapt to the pasting requirements around the bottom of the label body 1, further improving the tightness of the adhesion between the edge of the label body 1 and the surface to be pasted, and ensuring the effectiveness of the label.

[0036] Reference Figures 1-3 The microcapsule 4 is filled with modified polyvinyl alcohol. The modified polyvinyl alcohol is grafted with long-chain alkyl groups and has added formaldehyde-free crosslinking agents, which can further help enhance the adhesion between the label body 1 and the surface to be pasted, and improve the stability of the adhesion.

[0037] Working principle: When the label is first applied, the bottom of the label body 1 faces the surface to be adhered to. At this point, the adhesive layer 8, as the main adhesive structure, first contacts the surface and generates initial adhesion, thus initially fixing the label body 1 to the surface. During the application process, as pressure is applied to the label body 1, multiple micro-indentations 3 on the bottom of the label body 1 begin to function. These indentations trap some of the air generated during the application process, preventing air bubbles from forming between the label body 1 and the surface, thereby ensuring a smooth adhesion.

[0038] Simultaneously, under pressure, multiple microcapsules 4 at the bottom of the label body 1 rupture due to external force, releasing the modified polyvinyl alcohol (PVC) filling them. The released PVC further enhances the adhesion between the label body 1 and the surface being adhered to, improving the stability of the bond. Meanwhile, the rubber-based adhesive 2 around the bottom of the label body 1 maintains close contact with the edges of the surface during adhesion, providing additional adhesive support and strengthening the bond between the edges of the label body 1 and the surface, reducing the likelihood of edge lifting.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
