A type of easy-tear self-adhesive label

Abstract

This utility model relates to an easy-tear self-adhesive label, including a label body with an adhesive layer at the bottom. Multiple tear strips are provided on the label body, connected to it by dotted lines. One end of each tear strip is connected, forming a tear-off section at one end of the label body. The tear-off section has a conical structure with its tip pointing towards the edge of the label body. A tear handle is provided at the other end of the label body; the tear handle is a non-adhesive lug extending outwards from the label body. By setting multiple tear strips weakly connected by dotted lines to form a conical tear-off section on the label body, combined with the non-adhesive lug tear handle at the other end, "graded force reduction and step-by-step peeling" is achieved. During use, the tear strips can be easily peeled off one by one through the tear handle to gradually weaken the adhesive layer's bonding force. The remaining label body can then be easily peeled off using the tear handle, significantly reducing the difficulty of peeling, preventing label breakage or adhesive residue, and improving operational convenience and peeling integrity.

Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, specifically to an easy-tear self-adhesive label. Background Technology

[0002] Self-adhesive labels are widely used in packaging, labeling, and other fields due to their ease of application. However, traditional labels generally suffer from problems such as difficulty in removal, easy breakage, or adhesive residue. Current technologies typically remove labels by tearing them off as a whole. For large-area or highly adhesive labels, significant pulling force is required, which is not only inconvenient but may also damage the label or the surface of the object being applied. Some improved solutions incorporate tear-off edges or easy-tear lines, but due to the lack of a systematic force-relieving structure, problems such as uncontrollable tearing paths and high residue rates still exist. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an easy-tear self-adhesive label.

[0004] The purpose of this utility model can be achieved through the following technical solution: an easy-tear self-adhesive label, including a label body, an adhesive layer at the bottom of the label body, multiple tear strips on the label body, the tear strips being connected to the label body through dotted lines, one end of each tear strip being connected and forming a tear-off part at one end of the label body, the tear-off part having a conical structure with the tip pointing towards the edge of the label body, and a tear handle at the other end of the label body, the tear handle being a non-adhesive lug structure extending outward from the label body.

[0005] Preferably, the surface of the label body is provided with a protective film.

[0006] Preferably, the adhesive layer is provided with a fiber web.

[0007] Preferably, the multiple tear strips are arranged in parallel or radially, and the length direction of each tear strip is consistent with the tearing direction.

[0008] Preferably, the label body has notches on both sides of the tear-off portion.

[0009] Preferably, the end of the tear strip has an arc-shaped structure.

[0010] The beneficial effects of this utility model are as follows: by setting multiple tear strips weakly connected by dotted lines on the label body to form a conical tear section, and cooperating with the adhesive-free lug tear handle at the other end, "graded force relief - step-by-step peeling" is achieved. When in use, the tear strips can be easily peeled off one by one through the tear section to gradually weaken the adhesive layer's bonding force, and then the remaining label body can be peeled off with less effort through the tear handle, significantly reducing the difficulty of peeling off, avoiding label breakage or adhesive residue, and improving the convenience of operation and the integrity of peeling.

[0015] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0016] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1 to 2As shown, the structure of this utility model is as follows: an easy-tear self-adhesive label includes a label body 1, an adhesive layer 2 at the bottom of the label body 1, and multiple tear strips 3 on the label body 1. The tear strips 3 are connected to the label body 1 through dotted lines 4. One end of each tear strip 3 is connected and forms a tear-off part 5 at one end of the label body 1. The tear-off part 5 has a conical structure and the tip faces the edge of the label body 1. The other end of the label body 1 is provided with a tear handle 6, which is a non-adhesive lug structure extending outward from the label body 1. Specifically, the label body 1 is pasted to the surface of an object through the bottom adhesive layer 2. Its easy-tear function is achieved through a "graded stress relief - step-by-step peeling" mechanism: First, the multiple tear strips 3 are weakly connected to the label body 1 through a discontinuous connection structure formed by half-cutting or punching through the dotted lines 4. One end of each tear strip 3 converges to form a conical tear-off part 5, with the tip facing the edge of the label to form a stress concentration point, which facilitates the application of initial pulling force after the fingers pinch it. During tearing, the pulling force preferentially breaks the weak connections at the dotted line 4 along the conical tip, causing the tear strips 3 to separate from the label body 1 one by one, gradually peeling off the contact area between the adhesive layer 2 and the adhered object. After all the tear strips 3 are removed, the adhesive-free lug tear handle 6 at the other end of the label body 1 provides an independent point of force. By pinching the tear handle 6, a reverse pulling force is applied. Utilizing the lever principle, the lug acts as a fulcrum to extend the lever arm, further reducing the peeling resistance of the remaining adhesive layer 2, ultimately achieving easy tearing of the entire label. This design transforms the traditional "overall strong tearing" of labels into "first localized force relief, then overall peeling." Through the stress concentration effect of the dotted line 4 and the force-saving characteristics of the conical structure, the difficulty of tearing is significantly reduced, while avoiding label breakage or adhesive residue.

[0019] like Figure 2 As shown, the surface of the label body 1 is provided with a protective film 7. Specifically, the protective film 7 on the surface of the label body 1, such as a PET or OPP material film, forms a physical barrier by covering the printed graphic area, which can resist the damage to the label surface information by friction, moisture and ultraviolet rays.

[0020] like Figure 2 As shown, the adhesive layer 2 is provided with a fiber mesh 8. Specifically, the fiber mesh 8 in the adhesive layer 2, such as a polyester fiber mesh 8 grid, serves as a rigid reinforcing skeleton. The mesh structure evenly distributes the local tensile force during tearing to the entire adhesive layer 2 to prevent adhesive residue.

[0021] Furthermore, multiple tear strips 3 are arranged in parallel or radially, and the length direction of each tear strip 3 is consistent with the tearing direction. Specifically, when multiple tear strips 3 are arranged in parallel or radially, their length direction is consistent with the label tearing direction, maximizing the effective tensile force component: parallel arrangement is suitable for straight peeling scenarios, forming a uniform tensile force distribution and avoiding single strip overload breakage; radial arrangement is distributed in a fan shape with the hand-tear part 5 as the center, adapting to the needs of arc or curved surface peeling through tensile force components at different angles, and uniformly releasing the adhesive force of the adhesive layer 2. Both arrangement methods optimize the force transmission path to ensure stable force during the tearing process.

[0022] like Figure 1 As shown, the label body 1 has notches 9 on both sides of the tear section 5. Specifically, the local stress concentration at the notch 9 can reduce the initial force required to start the tear strip 3, and can also reduce the tearing or directional deviation of the tear strip 3 caused by force deviation, thereby improving the controllability of the peeling process.

[0023] like Figure 1 , Figure 2 As shown, the end of the tear strip 3 has an arc-shaped structure. Specifically, the smooth shape of the arc-shaped structure can reduce the resistance to the tear strip 3 during peeling, avoid the ends from hooking or getting stuck, and enable each tear strip 3 to complete the peeling action independently and smoothly, ultimately achieving the continuity and integrity of the label peeling.

[0024] In practical use, the label body 1 is adhered to the surface of the object through the bottom adhesive layer 2, the tear-off part 5 is located at one edge of the label, and the tear handle 6 is located at the other end. The tear strip 3 is weakly connected to the label body 1 through the dotted line 4, and initially remains intact. When the fingers pinch the conical tip of the tear-off part 5, a pulling force is applied outward to the label. The small area of ​​the tip of the conical structure forms a concentrated force point, allowing the initial pulling force to quickly break through the weak connection of the dotted line 4. The pulling force is transmitted along the length of the tear strip 3. Since one end of each tear strip 3 converges at the tear-off part 5, multiple tear strips 3 are simultaneously subjected to force when force is applied, and they separate from the label body 1 sequentially along the dotted line 4. The discontinuous structure of the dotted line 4 guides the breaking path, ensuring that the tear strip 3 detaches neatly along the preset trajectory, avoiding tearing the main body area of ​​the label body 1. When each tear strip 3 is peeled off, the adhesive layer 2 below it is taken away simultaneously, gradually reducing the contact area between the label body 1 and the object being adhered to, decomposing the overall adhesive force into multiple small resistances. After tearing off the tear strip 3, the tearing handle 6 is pinched and pulled to one side. At this time, the area of ​​the remaining adhesive layer 2 of the label body 1 has been greatly reduced, and the adhesive force has been significantly reduced due to the step-by-step unloading of force, making it easy to tear the entire label off the object surface. The pre-peeling of the tear strip 3 has disrupted the continuity of the adhesive layer 2. The remaining adhesive layer 2 is separated along the flat interface under the pulling force of the tearing handle 6, avoiding label breakage or adhesive residue caused by strong tearing.

[0025] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
