Description

Technical Field

[0001] This application relates to the field of label technology, and more particularly to an elastic label with high ductility. Background Technology

[0002] Elastic labels are a type of label made of elastic material (such as elastic cloth or elastic plastic film). They can expand and contract synchronously with the deformation of the object being labeled, such as stretching or bending, making them less likely to fall off or break. Their core features are elastic adaptation and firm adhesion. They are commonly found on surfaces of items that require frequent movement or have curves.

[0003] Currently, Chinese utility model patent application CN220886553U, published on May 3, 2024, discloses a high-toughness self-adhesive label, comprising a roll, with a backing paper wound around the outside of the roll, and multiple self-adhesive label bodies on the surface of the backing paper. Each of the multiple self-adhesive label bodies has a reinforcing edge on its surface. Multiple slots are formed on the inner wall of the roll. A first protective shell for providing protection is located at one end of the roll. A second protective shell for providing protection is located at the other end of the roll, and a connecting ring is fixedly connected to one side of the second protective shell, the connecting ring being compatible with the first protective shell. This utility model can provide sealed protection for self-adhesive labels, preventing dust, water, and other stains from adhering to the surface of the self-adhesive labels, making them convenient to use. It can also improve the toughness of the self-adhesive labels, preventing them from being torn.

[0004] In the application of high-toughness self-adhesive labels, the protective shell needs to be removed to access the label inside, increasing the operational process. While the protective shell effectively protects against external friction and moisture damage in high-toughness self-adhesive label applications, its independently sealed design adds an extra burden to the actual handling and use process, especially in high-frequency handling or one-handed operation scenarios. In daily consumer scenarios, ordinary users have higher requirements for ease of operation, and complicated handling processes may reduce the user experience, or even lead to situations where users abandon using the labels because they cannot open the protective shell smoothly.

[0005] Therefore, it is necessary to propose a highly elastic label to solve the above problems. Utility Model Content

[0006] This application provides a highly elastic label to improve the technical problem in related technologies where the label protection process adds extra burden and affects the user's product experience.

[0007] This application provides a highly elastic label with high ductility, including a protective shell, a roll disposed inside the protective shell, and label paper wound on the roll. The protective shell is characterized by having a discharge port, through which the label paper on the roll is discharged for use. The protective shell is provided with a clamping element at the position corresponding to the outlet, which is used to clamp the label paper for easy tearing and use later; The protective shell is equipped with a rotating shaft, and the roll is rotatably mounted on the rotating shaft. A rotation limiter is provided between the roll and the rotating shaft to prevent the label paper from becoming loose due to excessive rotation of the roll.

[0008] The technical solutions described above in this application embodiment have at least the following technical effects: By physically isolating the label paper from external environmental damage, dust, moisture, and oil contamination of the printing and adhesive layers on the label surface is prevented. At the same time, the clamping component prevents the label from being scratched or folded during carrying or storage. Furthermore, after the label paper is discharged from the outlet, the clamping force fixes the current position of the label paper, preventing the label from retracting into the shell. Finally, the rotating limiting component controls the rotation speed and amplitude of the roll through damping force or limiting structure, preventing excessive rotation of the roll due to external force and ensuring that the label is always neatly wound on the roll. The operation steps are simplified from "removing the shell → taking out the label → tearing off the release film" to "pulling the label → tearing off", reducing the single-step time by more than 50%.

[0009] In this embodiment, the clamping member includes a fixing block fixedly disposed on the protective shell and located at one end of the outlet, and a limiting ring fixedly disposed on the protective shell and located at the other end of the outlet. The clamping block is movably disposed within the limiting ring for abutting against the fixing block, thereby clamping the label paper.

[0010] This technical solution achieves adjustable and stable clamping of label paper through a combination of a fixed block, a limiting ring, and a movable clamping block. This ensures that the label is fixed in position during use and is adapted to the stretching characteristics of the highly elastic label paper. At the same time, the clamping block is made of elastic material, which can provide sufficient clamping force to prevent the label paper from retracting and avoid damage or scratches to the highly elastic label paper by hard materials, thus protecting the tensile properties of the label.

[0011] In this embodiment, a connecting groove is provided on the rotating shaft, and the rotation limiting member includes an abutment spring disposed in the connecting groove. A ball pin abuts against the abutment spring, and the abutment grooves corresponding to the positions of the ball pins are arranged in a ring array on the inner wall of the drum.

[0012] Through this technical solution, the rotating limiting component forms a detachable damping limiting structure by combining a connecting groove, abutment spring, ball pin, and abutment groove. This structure can precisely control the rotation amplitude of the roll, prevent the label paper from loosening, and adapt to the stretching and picking requirements of highly ductile labels.

[0013] In this embodiment, a triangular auxiliary push block is provided on the end of the clamping block away from the fixed block, a limit block is provided on the end of the clamping block close to the fixed block, and an array of abutment posts are provided on the upper surface of the clamping block to stabilize the clamping block.

[0014] This technical solution uses a triangular auxiliary push block as a force application handle for the clamping block. The triangular structure provides a clear force application point for the fingers. The limiting block restricts the maximum movement distance of the clamping block towards the fixed block, preventing excessive squeezing between the clamping block and the fixed block due to excessive pushing force, which could damage the label paper or destroy the clamping structure. The abutment post increases the contact area with the limiting ring, preventing excessive pushing speed.

[0015] In this embodiment, the protective shell is made of a transparent material.

[0016] This technical solution uses a transparent protective shell, whose core function is to visualize the label's status. While retaining the protective function, it solves the pain points of traditional opaque protective shells, which make it difficult to see the inside and judge the usage status, making the use and maintenance of labels more convenient.

[0017] In this embodiment, the label paper includes a base paper and label stickers adhered to the base paper, and an easy-tear line is provided between the base paper and two spaced label stickers.

[0018] This technical solution achieves precise and convenient separation of labels by combining the base paper and the easy-tear line, solving the problems of uneven tearing and easy tangling of traditional roll labels, while also being suitable for the characteristics of highly elastic labels.

[0019] In this embodiment, the label sticker includes a fiberglass wear-resistant layer, a PVC waterproof layer, an elastic fiber layer, a base layer, and a self-adhesive layer, which are distributed in sequence.

[0020] This technical solution achieves multiple functional enhancements, including wear resistance, water resistance, and tensile strength, while retaining high ductility, thus solving the problems of traditional elastic labels being easily worn, susceptible to water damage, and prone to breakage after stretching.

[0023] In the application of high-toughness self-adhesive labels, the protective shell needs to be removed to access the label inside, increasing the operational process. While the protective shell effectively protects against external friction and moisture damage in high-toughness self-adhesive label applications, its independently sealed design adds an extra burden to the actual handling and use process, especially in high-frequency handling or one-handed operation scenarios. In daily consumer scenarios, ordinary users have higher requirements for ease of operation, and complicated handling processes may reduce the user experience, or even lead to situations where users abandon using the labels because they cannot open the protective shell smoothly.

[0024] Based on this, in order to improve the technical problem in the related technology that the protection of labels adds an extra burden to the operation process and affects the user's product experience, the embodiments of this application provide the following solutions.

[0025] Please refer to the following: Figures 1 to 5This application provides a highly elastic label with high ductility. The highly elastic label includes a protective shell 1, a roll 2 disposed inside the protective shell 1, and label paper 3 wound on the roll 2. The protective shell 1 has a discharge port 11 through which the label paper 3 on the roll 2 is discharged for use. A clamping member 4 is provided at the position corresponding to the discharge port 11 on the protective shell 1 to clamp the label paper 3 for easy tearing and use. A rotating shaft 12 is provided inside the protective shell 1, and the roll 2 is rotatably disposed on the rotating shaft 12. A rotation limiting member 5 is provided between the roll 2 and the rotating shaft 12 to prevent the label paper 3 from loosening due to excessive rotation of the roll 2.

[0026] The highly elastic label provided in this embodiment physically isolates the label paper 3 from external environmental damage, preventing dust, moisture, and oil from contaminating the printing and adhesive layers on the label surface. Simultaneously, the clamping component 4 prevents the label from being scratched or folded during carrying or storage. Furthermore, after the label paper 3 is discharged from the outlet 11, the clamping force fixes its current position, preventing it from retracting into the casing. Finally, the rotating limiting component controls the rotation speed and amplitude of the roll 2 through damping force or the limiting structure, preventing excessive rotation of the roll 2 due to external forces and ensuring that the label is always neatly wound onto the roll 2. In this way, the highly elastic substrate is protected, the label paper 3 is prevented from being squeezed and rubbed during storage, and its tensile resilience is not diminished. The protective shell 1 isolates external pollution, and the clamping part 4 and the limiting part prevent excessive force when the label is torn, preventing the printing layer from cracking and the adhesive layer from falling off, ensuring that the label information is clear and the adhesion is reliable. At the same time, there is no need to disassemble the protective shell 1. The label can be pulled out directly from the outlet 11. After the clamping part 4 is fixed, it can be torn off. The operation steps are simplified from "disassembling the shell → taking out the label → tearing off the release film" to "pulling the label → tearing off", reducing the time of a single step by more than 50%.

[0027] In this embodiment, the clamping member 4 includes a fixing block 41 fixedly disposed on the protective shell 1 and located at one end of the outlet 11, and a limiting ring 42 fixedly disposed on the protective shell 1 and located at the other end of the outlet 11. The clamping block 43 is movably disposed within the limiting ring 42 for abutting against the fixing block 41, thereby clamping the label paper 3.

[0028] This configuration, through the combination of the fixed block 41, the limiting ring 42, and the movable clamping block 43, achieves adjustable and stable clamping of the label paper 3. This ensures the label's position is fixed during use while also accommodating the stretching characteristics of the high-strength label paper 3. Simultaneously, the clamping block 43, made of elastic material, provides sufficient clamping force to prevent the label paper 3 from retracting, while also preventing hard materials from damaging or scratching the high-strength label paper 3, thus protecting the label's stretchability. In this way, the user only needs to push the movable clamping block 43 to complete the clamping process without additional tools. Furthermore, the clamping position avoids the adhesive surface and printing area of ​​the label paper 3, preventing the adhesive layer from failing due to clamping or the printing layer from detaching due to friction, ensuring clear label information and reliable adhesion.

[0029] In this embodiment, a connecting groove 51 is provided on the rotating shaft 12, and the rotation limiting member 5 includes an abutment spring 52 disposed in the connecting groove 51, a ball pin 53 abutted by the abutment spring 52, and an abutment groove 54 corresponding to the position of the ball pin 53 is formed in a ring array on the inner wall of the drum 2.

[0030] With this configuration, the rotation limiter 5, through the combination of connecting groove 51, abutment spring 52, ball pin 53, and abutment groove 54, forms a detachable damping limit structure. This structure can precisely control the rotation amplitude of the roll 2, prevent the label paper 3 from loosening, and adapt to the stretching and picking requirements of high-strength labels. At the same time, when the label paper 3 is pulled to drive the roll 2 to rotate, the engagement of the ball pin 53 and the abutment groove 54 will generate a damping force, slowing down the rotation speed of the roll 2. Even if released, the roll 2 will not rotate due to inertia, preventing the label paper 3 from loosening and stacking. The discrete abutment groove 54 can achieve segmented limiting, making it convenient for users to accurately control the label picking length. The spherical design of the ball pin 53 and the elastic buffer of the spring avoid rigid friction between the limit structure and the roll 2, preventing damage to the inner wall of the roll 2 or the label paper 3. At the same time, it ensures that the roll 2 rotates smoothly and without jamming when the high-strength label is stretched.

[0031] In this embodiment, a triangular auxiliary push block 44 is provided on the end of the clamping block 43 away from the fixing block 41, a limit block 45 is provided on the end of the clamping block 43 close to the fixing block 41, and an array of abutment posts 46 are provided on the upper surface of the clamping block 43 to stabilize the clamping block 43.

[0032] With this configuration, the triangular auxiliary push block 44 serves as the force application handle for the clamping block 43. The triangular structure provides a clear force application point for the fingers. The limiting block 45 restricts the maximum movement distance of the clamping block 43 towards the fixed block 41, preventing excessive pressure between the clamping block 43 and the fixed block 41 due to excessive pushing force, which could damage the label paper 3 or destroy the clamping structure. The abutment post 46 increases the contact area with the limiting ring 42, preventing excessive pushing speed.

[0033] In this embodiment, the protective shell 1 is made of a transparent material.

[0034] With this design, the protective shell 1 is made of transparent material. Its core function is to make the label status visible. While retaining the protective function, it solves the pain point of traditional opaque protective shells 1, which make it difficult to see the inside and judge the usage status, making the use and maintenance of labels more convenient. It allows clear observation of whether the label paper 3 inside the protective shell 1 is loose, wrinkled, has worn printing layer, or contaminated adhesive layer, avoiding the waste of operation time by only discovering that the label is invalid after removal.

[0035] In this embodiment, the label paper 3 includes a base paper 31 and label stickers 32 adhered to the base paper 31. An easy-tear line 33 is provided between the base paper 31 and two spaced label stickers 32.

[0036] This design, through the combination of the base paper 31 and the easy-tear line 33, enables precise and convenient separation of the label sticker 32, solving the problems of uneven tearing and easy tangling of traditional roll labels, while also adapting to the characteristics of the highly elastic label sticker 32.

[0037] In this embodiment, the label sticker 32 includes a glass fiber wear-resistant layer 34, a PVC waterproof layer 35, an elastic fiber layer 36, a base layer 37, and an adhesive layer 38, which are distributed sequentially.

[0038] This design, while maintaining high elasticity, achieves multiple functional enhancements such as wear resistance, water resistance, and tensile strength, solving the problems of traditional elastic labels being prone to wear, water damage, and breakage after stretching. There's no need to add extra protective sleeves or coatings to the labels; the labels themselves can withstand daily damage, and the high durability reduces the need for frequent label replacements.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
