Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to an easy-tear self-adhesive label. Background Technology

[0002] In modern packaging, logistics, retail, and various product labeling fields, self-adhesive labels have become a common choice for product information labeling and decoration due to their convenient application characteristics. Among them, easy-tear self-adhesive labels have further increased their popularity due to their ease of application.

[0003] Traditional easy-tear self-adhesive labels are typically stored and transported by winding release paper onto label rollers. In practical applications, after a user applies a label, the remaining label roll is stored away if it is not needed immediately. However, current label roller designs have significant flaws, lacking effective securing mechanisms when not in use. Because the label roller structure is relatively independent and lacks a fixing device, it is easily affected by various unforeseen forces in the external environment during daily storage, such as collisions during warehouse handling or slight shifts in storage location, causing the label roller to rotate. Once the label roller rotates, the label roll, originally tightly wound on the roller, will gradually unwind due to centrifugal force and its own gravity, and in severe cases, may even completely unwind. This not only greatly affects the convenience of label roll storage and increases the time cost of rewinding, but may also cause the label surface to become contaminated with dust and stains, affecting the label's adhesion and appearance. More seriously, the unwinding of labels may cause damage and waste, resulting in additional economic losses in production and use. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an easy-tear self-adhesive label that can lock the label roller, allowing the label roll to be stably wound onto the label roller.

[0005] In view of this, the present invention provides an easy-tear self-adhesive label, including a bracket and a label roller mounted on the bracket, and a label body with release paper wound on the label roller. Limiting plates are provided at both ends of the label roller to limit the label roll. The label roller also includes a locking mechanism for fixing the label roller to prevent it from rotating. The locking mechanism includes a stud provided at the end of the label roller and a control component for controlling the start and stop of the label roller. The control component triggers and cooperates with the stud to lock the label roller so that it cannot rotate.

[0006] In the above technical solution, the control component is a fastening nut that is threadedly engaged with the stud. The fastening nut tightens the stud, preventing the label roller from rotating.

[0007] In any of the above technical solutions, the outer end of the stud is provided with a connecting section, a slot is provided in the connecting section, an elastic buckle is provided in the slot, the elastic buckle engages with the slot, and one end of the elastic buckle is provided with a handle to realize the operation of rotating the label roller.

[0008] In any of the above technical solutions, the bracket is further composed of two U-shaped frames. The connection between the two U-shaped frames is connected by a protrusion on one side and a groove on the other side. Both the protrusion and the groove are provided with through slots, and the through slots of the protrusion and the groove are connected. A bolt is inserted in the through slot, and a locking nut is provided on the bolt. The bracket composed of the two U-shaped frames can be disassembled to replace the label roll.

[0009] In any of the above technical solutions, a backing paper is provided at the bottom of the label body, and a tear-off end is provided on the front side of both the label body and the backing paper.

[0010] In any of the above technical solutions, a further feature is provided on the top rear side of the label body, which allows the label body to be easily torn off the item.

[0011] In any of the above technical solutions, the label body further includes a base layer, a self-adhesive layer at the bottom of the base layer, a fireproof layer at the top of the base layer, a wear-resistant layer at the top of the fireproof layer, a waterproof layer at the top of the wear-resistant layer, and a hydrophobic layer at the top of the waterproof layer.

[0012] The beneficial effects of this utility model are:

[0013] 1. The locking mechanism effectively fixes the label roller, preventing it from rotating due to external force when it is rolled up and stored. This prevents the label roll from unwinding and unwinding, greatly improving the stability of the label roll during storage and reducing the handling costs caused by the labels unwinding.

[0014] 2. The bracket is designed as a structure in which two U-shaped frames are connected together, which allows users to easily disassemble the bracket when changing the label roll, significantly shortening the time required to change the label roll. For work scenarios that require frequent use of labels and therefore frequent replacement of label rolls, this design can greatly improve work efficiency and reduce the downtime caused by changing label rolls.

[0015] 3. The tear-off end allows users to easily pinch and apply force to quickly peel the label off the backing paper, which is especially suitable for scenarios where a large number of labels need to be retrieved quickly, such as bulk labeling of logistics and express parcels, and quick replacement of shelf labels in retail, effectively improving work efficiency.

[0016] 4. Once the label is affixed to the surface of the item, when it needs to be replaced or is no longer needed, the user can easily apply force using the easy-tear protrusion to peel the label off the surface of the item, greatly improving the efficiency of label replacement and reducing labor costs.

[0017] 2. The base layer serves as the foundation, with the self-adhesive layer at the bottom ensuring the label adheres firmly to the surface of the item; the fire-retardant layer effectively resists open flames or high-temperature radiation in high-temperature environments, reducing the risk of fire damage to the label; the abrasion-resistant layer prevents the label from becoming blurred or damaged due to friction during daily use; the waterproof layer prevents water penetration, preventing the label from being affected by moisture; the hydrophobic layer utilizes a special microstructure or chemical substance to cause water to form droplets on its surface, making it difficult for water to adhere and penetrate, protecting the label information from water damage, maintaining the integrity and readability of the label, thereby extending the label's lifespan.

[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0025] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0026] Example 1:

[0027] like Figures 1-3 As shown, this embodiment provides an easy-tear self-adhesive label, including a bracket 1 and a label roller 2 rotatably mounted on the bracket 1, and a label body 4 with release paper 3 wound on the label roller 2. Limiting plates 5 are provided at both ends of the label roller 2. The limiting plates 5 are used to restrict the label roll. It also includes a locking mechanism 6 for fixing the label roller 2 to prevent it from rotating. The locking mechanism 6 includes a stud 61 provided at the end of the label roller 2 and a control component for controlling the start and stop of the label roller 2. The control component triggers and cooperates with the stud 61 to lock the label roller 2, so that it cannot rotate.

[0028] In this technical solution, the locking mechanism 6 effectively secures the label roller 2, preventing it from rotating due to external force during storage. This prevents the label roll from unwinding and unraveling, significantly improving its stability during storage and reducing handling costs caused by label unraveling. Preventing label roll unraveling avoids dust and stains on the label surface, maintaining the label's adhesion and aesthetics, ensuring its proper function in subsequent use, and reducing problems such as unclear product labeling due to label quality issues. It also prevents damage and waste caused by label unraveling, saving costs in production and use, reducing unnecessary economic expenditures, and improving resource utilization.

[0029] Working Principle: Limiting plates 5 are installed at both ends of the label roller 2. Their main function is to limit the axial position of the label roll on the label roller 2, preventing axial displacement of the label roll during rotation. Simultaneously, a stud 61 is installed at the end of the label roller 2. The stud 61 is a key component of the locking mechanism 6, providing the basic structure for subsequent locking operations. When the user finishes labeling and needs to retract the label roll, the operating control component engages with the stud 61. Since the stud 61 is fixedly connected to the label roller 2, the control component gradually creates resistance to the label roller 2 during the engagement process. As the engagement depth increases, the friction gradually increases until the label roller 2 is completely locked and cannot rotate. When the label roll needs to be used again, the control component is operated in reverse to release the lock on the label roller 2, restoring the label roller 2 to a rotatable state, allowing the user to normally retrieve the labels.

[0030] like Figure 1 and Figure 3 As shown, in this embodiment, the optimized control component is a fastening nut 62 that engages with the stud 61 via a thread. The fastening nut 62 tightens the stud 61, preventing the label roller 2 from rotating.

[0031] In this technical solution, the rotation of the label roller 2 due to various external forces during storage is completely eliminated. The label roller 2 is firmly fixed by the tight engagement of the fastening nut 62 and the stud 61, ensuring that the label roll remains neatly wound during storage, preventing unwinding and unraveling. This significantly enhances the safety and stability of the label roll during storage, reducing the hassle and cost of reorganizing due to label scattering. The stable storage state of the label roll effectively prevents the label surface from contacting external dust and stains. This ensures perfect adhesion and a clean, aesthetically pleasing label appearance during subsequent use, effectively guaranteeing clear presentation of product identification information and preventing damage to the product image due to label quality issues. It successfully avoids damage and waste caused by label unwinding, effectively saving unnecessary economic investment in production and use. Whether in label inventory management during production or label consumption in actual use scenarios, it significantly improves resource utilization efficiency and reduces overall costs.

[0032] Working Principle: Limiting plates 5 are installed at both ends of the label roller 2. Their main function is to restrict the axial movement of the label roll on the label roller 2, ensuring that the label roll does not shift axially during rotation. Simultaneously, studs 61 are precisely installed at the end of the label roller 2. These studs 61 are securely connected to the label roller 2 and rotate synchronously with it, laying a crucial foundation for subsequent locking operations. When the user finishes labeling and is ready to retract the label roll, they operate the fastening nut 62, which has an internal thread that matches the stud 61. The user manually rotates the fastening nut 62, gradually bringing it closer to the end of the label roller 2 along the thread direction of the stud 61. As the fastening nut 62 is continuously screwed in, its contact area with the end of the label roller 2 gradually increases, and the pressure exerted by the fastening nut 62 on the label roller 2 also continuously increases. Due to the tight thread fit between the fastening nut 62 and the stud 61, this pressure is converted into strong friction, hindering the rotation of the label roller 2. As the fastening nut 62 is continuously tightened, the frictional force continues to increase until it completely overcomes the potential rotational tendency of the label roller 2 caused by external forces, firmly locking the label roller 2 and preventing it from rotating. When a label needs to be retrieved again, the user rotates the fastening nut 62 in the opposite direction, gradually moving it away from the end of the label roller 2 along the thread direction of the stud 61. As the fastening nut 62 is unscrewed, its pressure and friction on the label roller 2 gradually decrease. When the fastening nut 62 is unscrewed to a certain extent, the obstruction to the label roller 2 completely disappears, the label roller 2 returns to a free rotation state, and the user can smoothly retrieve the label.

[0033] Example 2:

[0034] This embodiment provides an easy-tear self-adhesive label, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the stud 61 is optimized to have a connecting section 7 at its outer end, a slot 71 is provided in the connecting section 7, an elastic buckle 72 is provided in the slot 71, the elastic buckle 72 is engaged with the slot 71, and one end of the elastic buckle 72 is provided with a handle 73 to enable the label roller 2 to rotate.

[0036] In this technical solution, when the user needs to rotate the label roller 2 to retrieve a label, they grasp the handle 73 and apply external force. The rotation of the handle 73 causes the elastic buckle 72 to rotate as well. The elastic buckle 72 is connected to the stud 61 through the slot 71, which in turn causes the stud 61 to rotate. Because the stud 61 is securely connected to the label roller 2, the rotation of the stud 61 ultimately rotates the label roller 2. The user can then easily control the label roller 2 by rotating the handle 73 to complete the label retrieval operation. During the rotation, the elastic buckle 72 remains engaged with the slot 71, ensuring that the rotation of the handle 73 is stably transmitted to the stud 61 and the label roller 2. When the label roller 2 is finished using and needs to be stored, the elastic buckle 72 is engaged with the slot 71, allowing the buckle to be removed from the slot 71 and the handle 73 to be taken off. This prevents the handle 73 from rotating the stud 61 and the label roller 2 during shaking, ensuring that the label roll remains neatly wound during storage. This effectively prevents unwinding and uncoiling, maintaining the safety and quality of the labels. This provides users with a convenient way to rotate the label roller 2. Compared to the traditional method of manually rotating the label roller 2, operating with the handle 73 is more labor-saving and precise, especially in scenarios where the label roller 2 is frequently used for label retrieval, greatly improving operational efficiency and reducing the user's workload.

[0037] Example 3:

[0038] This embodiment provides an easy-tear self-adhesive label, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] like Figure 2 and Figure 4 As shown, in this embodiment, the optimized bracket 1 is composed of two U-shaped frames 11U. The connection between the two U-shaped frames 11U is connected by a protrusion 12 on one side and a groove 13 on the other side. Both the protrusion 12 and the groove 13 are provided with through slots 14, which are connected to each other. A bolt 15 is inserted in the through slot 14, and a locking nut 16 is provided on the bolt 15. The bracket 1 composed of the two U-shaped frames 11U can be disassembled to replace the label roll.

[0040] In this technical solution, the bracket 1 is designed as a structure consisting of two U-shaped frames 11U connected together, allowing users to easily disassemble the bracket 1 when changing label rolls. Traditional one-piece brackets 1 often obstruct the removal and installation of the label roller 2, while this detachable design greatly simplifies this process and significantly reduces the time required to change label rolls. For work scenarios that require frequent label use and thus frequent label roll changes, such as labeling logistics packages and price tag replacement in retail, this design can greatly improve work efficiency and reduce downtime caused by label roll changes.

[0041] Working principle: When the protrusion 12 and the groove 13 are accurately aligned, their through slots 14 are connected, forming a complete channel through which the bolt 15 can pass. After the bolt 15 passes through the through slot 14, the locking nut 16 is tightened. Through the tightening action of the locking nut 16 on the bolt 15, the two U-shaped frames 11U are firmly connected together, thus forming a stable support structure 1 for supporting and fixing the label roller 2. When it is necessary to replace the label roll, first loosen the locking nut 16 and pull the bolt 15 out of the through slot 14 connecting the protrusion 12 and the groove 13. At this time, the connection constraint between the two U-shaped frames 11U disappears, and the operator can easily separate the two U-shaped frames 11U. After separation, the U-shaped frames 11U no longer form a surrounding support for the label roller 2, and the label roller 2 along with the label roll can be easily removed from the support 1 for replacement with a new label roll. After replacing the label roll, place the label roller 2 back in the appropriate position, then accurately align the protrusions 12 and grooves 13 of the two U-shaped frames 11U, align the through grooves 14, insert the bolts 15 and tighten the locking nuts 16, reassemble the bracket 1, and complete the entire label roll replacement process.

[0042] Example 4:

[0043] This embodiment provides an easy-tear self-adhesive label, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] like Figure 5 As shown, in this embodiment, the bottom of the label body 4 is provided with a backing paper 8, and both the label body 4 and the backing paper 8 are provided with tear-off ends 9 on their front sides.

[0045] In this technical solution, tear-off tips 9 are provided on the front sides of both the label body 4 and the backing paper 8, greatly facilitating users in taking individual labels from the label roll. Traditional self-adhesive labels require users to carefully pry open a corner with their fingernails or other sharp objects when separating the label from the backing paper 8, a cumbersome operation that can easily damage the label. The tear-off tips 9, however, allow users to easily grasp and apply force to quickly tear the label off the backing paper 8. This is particularly suitable for scenarios requiring rapid retrieval of large quantities of labels, such as bulk labeling of logistics and express parcels, and rapid replacement of shelf labels in retail, effectively improving work efficiency.

[0046] The tear-off end 9 provides a stable and easy-to-apply point for label separation. By applying appropriate force, it can be ensured that the label is evenly stressed during the separation process from the backing paper 8, reducing the occurrence of damage such as tearing and deformation due to excessive local stress, ensuring the integrity of the label, and thus ensuring that the information it carries can be clearly and completely displayed after the label is pasted on the surface of the item, improving the quality and aesthetics of product labeling.

[0047] like Figure 1 and Figure 5 As shown, in this embodiment, the label body 4 is optimized by having an easy-tear ridge 10 on the top rear side, which allows the label body 4 to be easily torn off the item.

[0048] In this technical solution, an easy-tear raised strip 10 is provided on the top rear side of the label body 4, providing users with a convenient and quick way to remove the label. Once the label is affixed to the surface of an item, when it needs to be replaced or is no longer needed, the user can easily peel the label off the surface without the need for additional tools, simply by applying force using the easy-tear raised strip 10. This design is particularly practical in scenarios where labels need to be frequently changed, such as product packaging updates or changes to item information, greatly improving the efficiency of label replacement and reducing labor costs.

[0049] Traditional label removal methods can damage the surface of the item due to improper force or excessively strong adhesive, leaving glue residue or scratches. The Easy-Tear Embedded Strip 10 design helps users better control the force and angle of tearing the label, ensuring even pressure during removal and minimizing the risk of damage to the item's surface, protecting its appearance and original value. Whether it's packaging labels for valuable goods or labels on relatively fragile items like electronics and furniture, the Easy-Tear Embedded Strip 10 effectively provides protection.

[0050] By improving the ease and security of label removal, the Easy-Tear Embossed Strip 10 expands the application range of labels. It enables widespread use in fields where the integrity of the item's surface is paramount, such as art displays and high-end electronic product labeling. Simultaneously, for scenarios requiring temporary labeling for information annotation, such as conference material categorization and temporary exhibition signage, the Easy-Tear Embossed Strip 10 makes label use more flexible, eliminating concerns about irreversible damage to items when removing labels.

[0051] When a user needs to peel the label off an item, they first pinch the easy-tear strip 10 on the top rear side of the label body 4 with their fingers. Because the easy-tear strip 10 is located on the top rear side of the label, the user can naturally apply force at an upward angle after pinching the strip. This angle helps to break the adhesive bond between the label and the item surface. As the user gradually applies force, the easy-tear strip 10 causes the label body 4 to begin peeling off from the item surface. During the peeling process, the easy-tear strip 10 disperses the pulling force, ensuring that the adhesive force between the label and the item surface is evenly overcome, avoiding tearing or residue caused by excessive localized force on the label. With continued application of force, the label is gradually and completely peeled off the item surface along the direction guided by the easy-tear strip 10.

[0052] like Figure 5 As shown, in this embodiment, the optimized label body 4 includes a base layer 41, a self-adhesive layer 42 at the bottom of the base layer 41, a fireproof layer 43 at the top of the base layer 41, a wear-resistant layer 44 at the top of the fireproof layer 43, a waterproof layer 45 at the top of the wear-resistant layer 44, and a hydrophobic layer 46 at the top of the waterproof layer 45.

[0053] In this technical solution, the base layer 41 is generally made of a material with high strength and good flexibility, such as paper fiber or plastic film. Its main function is to provide structural support for the entire label body 4, giving the label a certain degree of shape stability, while ensuring that other functional layers can be firmly attached. The flexibility of the base layer 41 ensures that the label can fit well onto the surface of objects of different shapes during the pasting process, while its strength can withstand the external forces such as stretching and bending during daily use, maintaining the integrity of the label.

[0054] The self-adhesive layer 42 is located at the bottom of the base layer 41 and is composed of an adhesive material. When the label is applied, the self-adhesive layer 42 is in close contact with the surface of the item, and the van der Waals forces and chemical bonds between molecules make the label firmly adhered to the item. Its adhesiveness is specially formulated to ensure that the label will not easily fall off under normal use, and that when removal is needed, the label can be separated from the surface of the item with appropriate force, while minimizing adhesive residue.

[0055] The fireproof layer 43 is typically made of flame-retardant materials, such as polymeric materials or inorganic fire-retardant materials with added flame retardants. When exposed to a fire source, the flame-retardant components in the fireproof layer 43 undergo a series of physical and chemical changes. For example, some flame retardants decompose upon heating to produce non-flammable gases, diluting the oxygen concentration in the surrounding environment and inhibiting the combustion reaction; some inorganic fire-retardant materials form a heat insulation barrier at high temperatures, preventing heat from being transferred to the interior of the label, thereby protecting the base layer 41 and other functional layers from being burned by flames and effectively extending the label's survival time in a fire environment.

[0056] The wear-resistant layer 44 is made of materials with high hardness and strong wear resistance, such as polyurethane coating or alumina ceramic film. During label use, when the surface is subjected to friction, the wear-resistant layer 44, with its own hardness and special structure, can resist the frictional force and reduce wear on the label surface. For example, the polyurethane coating has good flexibility and wear resistance, and can undergo elastic deformation when subjected to friction, absorbing and dispersing the frictional force, preventing the base material 41 from being directly worn, and maintaining the clear readability of the information on the label surface.

[0057] The waterproof layer 45 is typically made of high-performance waterproof polymers, such as polyethylene and polypropylene, forming a continuous waterproof barrier layer. When water comes into contact with the waterproof layer 45, due to the molecular structure of the material, water molecules cannot penetrate the waterproof layer 45 to enter the label, thus providing waterproofing. The hydrophobic layer 46 usually uses special surface treatment techniques to give the label surface extremely low surface energy, such as a fluorinated compound coating. When water comes into contact with the surface of the hydrophobic layer 46, it forms water droplets due to surface tension, preventing it from spreading and penetrating the label surface, further enhancing the label's waterproof performance and ensuring normal use in humid environments.

[0058] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
