Description

Technical Field

[0001] This utility model relates to the field of decorative sticker technology, and in particular to an easy-to-tear beaded sticker. Background Technology

[0002] This easy-to-tear beaded sticker is a convenient DIY decoration sticker. It features removable acrylic adhesive and a double-sided graded release film, along with a laser pre-cut design, allowing for easy one-handed removal. The beads have rounded edges and the adhesive layer is compliant with child safety standards. It is compatible with paper, plastic, glass, and other substrates, making it suitable for DIY crafts and commercial decorations. It balances easy tearing and adhesion while reducing usage costs and time.

[0003] An easy-to-tear beaded sticker includes: a substrate layer made of flexible polymer; beads made of transparent resin molded by injection molding and hot pressing, with an anti-slip coating on the surface; a release layer including a base film and a silicone oil coating; and a through-cut line and an auxiliary tearing notch between the substrate and the release layer.

[0004] Existing traditional beaded stickers have several drawbacks. They lack a precise tear-off structure and have no pre-cut design, requiring users to tear them manually or cut them with scissors. This can easily lead to problems such as uneven tearing, tearing of the substrate layer, and beads falling off. This is especially difficult for children or users with poor fine motor skills, making it impossible to tear them off in segments with precision. Furthermore, the release layer of traditional beaded stickers has an unbalanced performance. The silicone oil coating of traditional release layers is often a simple application process that does not control surface energy and peel force. If the peel force is too high, it requires force to tear off, which can easily damage the substrate layer and the bead layer. If the peel force is too low, the stickers can easily detach from the release layer during storage, causing them to stick together. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-tear beaded sticker, which aims to improve the lack of a precise tearing structure in traditional equipment, the lack of pre-cut design in traditional stickers, the need for users to tear them manually or cut them with scissors, and the fact that the silicone oil coating of traditional release layers is mostly a simple coating process that does not control the surface energy and peel force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-tear beaded sticker includes a substrate layer, the surface of which is provided with a pre-cut line extending in a preset direction, a connecting rope slidably connected to the inner wall of the substrate layer, and beads slidably connected to the outer wall of the connecting rope, the pre-cut line penetrating the substrate layer and the release layer, the pre-cut line forming a continuous discontinuous cutting structure, the pre-cut line enabling the sticker to be torn off in segments.

[0007] As a further description of the above technical solution: The substrate layer is made of a flexible polymer material selected from polyethylene terephthalate.

[0008] As a further description of the above technical solution: The beads are arranged in a regular pattern on the outer wall of the connecting rope, and the beads are made of transparent resin.

[0009] As a further description of the above technical solution: The release layer includes a base film and a silicone oil coating.

[0010] As a further description of the above technical solution: The pre-cut line is straight, and auxiliary tearing notches are provided on both sides of the pre-cut line.

[0011] As a further description of the above technical solution: The surface of the beads is provided with an anti-slip coating, which is made of nano-silica particles and elastomer composite, and the beads are arranged in a ring.

[0012] As a further description of the above technical solution: The base film is a biaxially oriented polypropylene film, and the silicone oil coating is a free radical cured silicone coating.

[0013] As a further description of the above technical solution: The silicone oil coating contains a fluorine modifier, which reduces the adhesion between the silicone oil coating and the substrate layer.

[0014] This utility model has the following beneficial effects: In this invention, the collaborative design of pre-cut lines and auxiliary tear-off notches effectively solves the problem of traditional stickers lacking a precise tear-off structure: the pre-cut lines penetrate the substrate layer and release layer to form a continuous break point structure, ensuring that the two layers separate synchronously during tearing, avoiding release layer residue or substrate layer tearing; the auxiliary tear-off notches reduce tearing resistance, and precise segmented tearing can be achieved along the pre-cut lines without the need for tools.

[0015] 2. In this utility model, by optimizing the material and coating of the release layer, the defects of uncontrolled peel force and easy residue of traditional release layers are precisely solved: the release layer uses glassine paper or biaxially oriented polypropylene base film, combined with free radical curing silicone oil coating, which ensures easy tearing and avoids easy adhesion.

[0018] 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.

[0019] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an easy-to-tear beaded sticker, comprising a substrate layer 1, which is the basic support structure of the beaded sticker, supporting components such as pre-cut lines 2 and connecting ropes 4. The surface of the substrate layer 1 is provided with pre-cut lines 2 extending in a preset direction. The inner wall of the substrate layer 1 is slidably connected to the connecting ropes 4, and the outer wall of the connecting ropes 4 is slidably connected to beads 6. The connecting ropes 4 are used to string the beads 6 together, allowing the beads 6 to slide on their outer wall. The pre-cut lines 2 penetrate the substrate layer 1 and the release layer 3, forming a continuous discontinuous cutting structure. The pre-cut lines 2 enable the sticker to be torn off in segments. The substrate layer 1 is made of a flexible polymer material selected from polyethylene terephthalate.

[0020] Reference Figure 1 and Figure 2 The beads 6 are arranged in a regular pattern on the outer wall of the connecting rope 4. The beads 6 are made of transparent resin. The release layer 3 includes a base film 7 and a silicone oil coating 8, which facilitates the separation of the sticker from the carrier. The pre-cut line 2 is straight in shape, and auxiliary tear-off notches 5 are provided on both sides of the pre-cut line 2 to assist the user in tearing off the sticker. The surface of the beads 6 is provided with an anti-slip coating 9, which is made of nano-silica particles and elastomer composite to increase the anti-slip performance of the beads 6. The beads 6 are arranged in a ring. The base film 7 is a biaxially oriented polypropylene film. The silicone oil coating 8 is a free radical cured organosilicon coating. A fluorine modifier is added to the silicone oil coating 8 to reduce the adhesion between the silicone oil coating 8 and the substrate layer 1.

[0021] Working Principle: First, the easy-to-tear beaded sticker achieves a segmented tearing and functional integration working logic through multi-structure collaboration. The substrate layer 1, as the core supporting body, uses polyethylene terephthalate for flexible adaptability. Pre-cut lines 2 on its surface, with a continuous discontinuous structure, penetrate the substrate layer 1 and release layer 3, forming the physical basis for segmented tearing. These discontinuities maintain the overall connectivity of the sticker while reducing tearing resistance through localized weak points. Release layer 3 consists of a base film 7 and a silicone oil coating 8, which together allow the sticker to be easily peeled from the supporting surface. Connecting cord 4 penetrates the inner wall of the substrate layer, and beads 6 are regularly arranged and fitted onto the outer wall of connecting cord 4. Their transparent resin material, combined with the surface anti-slip coating 9, provides both decorative function and enhances grip stability during operation through friction enhancement.

[0022] During use, the user applies force using the auxiliary tearing notches 5 on both sides of the pre-cut line 2. The break point structure guides the pre-cut line to break along a preset direction, completing the segmented separation of the substrate layer 1. During the tearing process, the silicone oil coating 8 of the release layer 3 continuously weakens the peeling resistance, while the base film 7 ensures the integrity of the release layer. The beads 6 on the connecting cord 4 are constrained by the anti-slip coating 9, preventing them from sliding during operation and maintaining the structural shape. The segmented stickers can function independently, while the combination of the connecting cord 4 and the beads 6 strengthens the overall structure and allows for expanded usage scenarios after the stickers are used, thanks to the decorative and tactile appeal of the beads. The design of the pre-cut line 2 balances structural integrity and ease of tearing, allowing the stickers to maintain their whole shape when stored and to be segmented as needed during use, achieving a unified closed loop of function and experience.

[0023] 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.
