Technical Field
[0001] This utility model relates to the field of self-adhesive labels, and in particular to a self-adhesive label with waterproof function. Background Technology
[0002] Self-adhesive labels, also known as pressure-sensitive labels, are mainly used on liquid detergent products and mass-market personal care products. Film-type materials are mainly used on mid-to-high-end daily chemical products. Mass-market personal care products and household liquid detergents account for a large proportion of the market. Generally, self-adhesive labels have a waterproof layer on the surface, which prevents water from breaking the label after it is stuck in the designated position. Waterproof self-adhesive labels are usually designed to meet the waterproof performance requirements of labels in specific application scenarios. These labels can be used in damp or watery conditions without easily breaking or falling off, thus maintaining the integrity and readability of the label.
[0003] In related technologies, during use, workers will stick self-adhesive labels to the opening of the box to seal it. Self-adhesive labels are a type of safety sticker, and the box can only be opened by tearing off the self-adhesive label. Generally, the self-adhesive label is located at the fold of the box. During transportation and use, the outer wall of the box is easily rubbed, bumped, and comes into contact with water, which can cause the text on the self-adhesive label to become blurred and difficult to distinguish. Thus, the protective and information marking functions are lost.
[0004] Therefore, it is necessary to provide a self-adhesive label with waterproof function to solve the above-mentioned technical problems. Utility Model Content
[0005] To address the technical problem that the adhesive labels are located at the fold of the box, and the outer wall of the box is easily rubbed and bumped during transportation and use, causing the text on the surface of the adhesive labels to become blurred and difficult to distinguish, thus losing the protective and information marking functions, this utility model provides an adhesive label with waterproof function.
[0006] This utility model provides a waterproof self-adhesive label, comprising: an outer frame, wherein the inner surface of the outer frame is provided with a base film, an adhesive layer, a substrate, a coating layer, and a cover film; the lower surface of the adhesive layer is adhered to the upper surface of the base film, the upper surface of the adhesive layer is adhered to the lower surface of the substrate, the upper surface of the substrate is adhered to the upper surface of the coating layer, the upper surface of the coating layer is adhered to the lower surface of the cover film, the upper surface of the cover film is at the same horizontal line as the upper surface of the outer frame, and the lower surface of the base film is at the same horizontal line as the upper surface of the outer frame; and
[0007] A protective film is disposed above the cover film and the outer frame to increase the protective performance of the outer frame and the cover film.
[0008] Preferably, the outer frame has an arc-shaped groove inside, and a first patch is fixedly connected to one side of the bottom film. The first patch extends away from the bottom film and is located inside the arc-shaped groove.
[0009] Preferably, a second patch is fixedly connected to one side of the substrate, and a pad is fixedly connected below the second patch. The pad is located above the first patch and leaves a gap between the first patches.
[0010] Preferably, grooves are provided on both sides of the base film, adhesive layer, substrate, coating and cover film, and limiting blocks are fixedly connected to both sides of the inner wall of the outer frame, with one side of the two limiting blocks extending into the interior of the two grooves.
[0011] Preferably, the substrate has two symmetrically formed dotted grooves inside, the two dotted grooves extend away from the side of the second patch, and one side of the two dotted grooves communicates with the interior of the groove.
[0012] Preferably, the outer frame and the upper surface of the limiting block are consistent, and the upper part of the limiting block is attached to the lower part of the protective film.
[0013] Compared with related technologies, the self-adhesive label with waterproof function provided by this utility model has the following beneficial effects:
[0014] 1. The self-adhesive label is made by tearing off the bottom film, exposing the adhesive layer to the air. The adhesive layer is then placed at the opening of the box, covering the opening and firmly adhering the substrate to it. The outer frame is then peeled off, separating it from the protective film. Once the substrate is firmly bonded to the box, it supports the coating. Product information can be printed on the coating surface, enhancing the label's advertising effectiveness. The top surface of the coating is protected by a highly transparent and wear-resistant film made of a durable material. This film does not affect the information on the coating surface, while increasing its security, reducing water and fire damage, and extending its lifespan. The bottom and protective films protect the substrate and coating, increasing safety during transportation. The covering film further protects the substrate and coating during use, increasing wear resistance, safety, and lifespan.
[0015] 2. The adhesive layer, substrate, coating, and cover film are stacked sequentially on top of the bottom film. The outer frame is mainly used for protection during transportation. Gaps are left between the outer frame and the bottom film, adhesive layer, substrate, coating, and cover film to facilitate separation. The limiting block is located inside the groove and sequentially limits the bottom film, adhesive layer, substrate, coating, and cover film, increasing the stability of the bottom film, adhesive layer, substrate, coating, and cover film inside the outer frame and reducing shaking. To tear the substrate, the worker will pick up the second patch and pull it upwards. When pulled to the dotted groove inside the groove, the dotted groove will tear to one side of the substrate. The substrate can be torn at the box interface. The torn substrate can prevent the label from being reused, reducing the problem of reusing the box after separation and increasing product safety.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figures 1 to 4A waterproof self-adhesive label includes: an outer frame 1 and a protective film 7. The outer frame 1 has a base film 2, an adhesive layer 3, a substrate 4, a coating 5, and a cover film 6 inside. The lower part of the adhesive layer 3 is attached to the upper part of the base film 2, the upper part of the adhesive layer 3 is attached to the lower part of the substrate 4, the upper part of the substrate 4 is attached to the upper part of the coating 5, the upper part of the coating 5 is attached to the lower part of the cover film 6, the upper surface of the cover film 6 is at the same level as the upper surface of the outer frame 1, the lower part of the base film 2 is at the same level as the upper part of the outer frame 1, and the protective film 7 is disposed above the cover film 6 and the outer frame 1 to increase the protective performance of the outer frame 1 and the cover film 6.
[0023] In this way, when the worker needs to use the self-adhesive label, the worker first picks up the outer frame 1, turns the bottom of the outer frame 1 over so that it faces the outside, then tears off the bottom film 2 to expose the adhesive layer 3 to the air surface, and then places the adhesive layer 3 at the opening of the box. The adhesive layer 3 covers the opening of the box and will firmly stick the base 4 to the opening of the box. Then the worker peels off the outer frame 1, and the outer frame 1 and the protective film 7 will be separated from the covering film 6.
[0024] When the substrate 4 is firmly bonded to the box, it supports the coating 5. Product information can be printed on the surface of the coating 5, which can enhance the promotional effectiveness of the self-adhesive label. The upper surface of the coating 5 is protected by a covering film 6. The covering film 6 is made of a highly transparent and wear-resistant material, which does not affect the information on the surface of the coating 5, while increasing the security of the information on the surface of the coating 5, reducing water and fire damage, and increasing service life. Through the protection of the bottom film 2 and the protective film 7, the substrate 4 and the coating 5 can be protected, increasing safety during transportation. The covering film 6 can protect the substrate 4 and the coating 5 during use, increasing wear resistance and safety, and increasing service life.
[0025] The outer frame 1 has an arc-shaped groove 12 inside. A first patch 21 is fixedly connected to one side of the bottom film 2. The first patch 21 extends away from the bottom film 2 and is located inside the arc-shaped groove 12. The bottom film 2 protects the adhesive layer 3, reduces the contact between the adhesive layer 3 and dust, and maintains the adhesiveness of the adhesive layer 3. The bottom film 2 and the first patch 21 are integrally connected. The side of the first patch 21 closest to the bottom film 2 extends outward, which makes it convenient for workers to detach the bottom film 2 from the adhesive layer 3. When the adhesive layer 3 is detached from the bottom film 2, it can be covered on the surface of the item to be pasted.
[0026] Preferably, a second patch 42 is fixedly connected to one side of the substrate 4, and a pad 43 is fixedly connected below the second patch 42. The pad 43 is located above the first patch 21 and a gap is left between the first patches 21. The second patch 42 and the pad 43 are located directly above the first patch 21. The gap between the pad 43 and the first patch 21 facilitates the separation of the bottom film 2 and the adhesive layer 3 through the first patch 21. When the adhesive layer 3 is bonded to the box, the substrate 4 covers the surface of the box. When the box is in contact with the substrate 4, the bottom of the pad 43 is in contact with the box body. The pad 43 supports the second patch 42, so that the second patch 42 and the top of the substrate 4 are at the same horizontal height.
[0027] Specifically, grooves 61 are provided on both sides of the base film 2, adhesive layer 3, substrate 4, coating 5, and cover film 6. Limiting blocks 11 are fixedly connected to both sides of the inner wall of the outer frame 1. One side of the two limiting blocks 11 extends into the two grooves 61. The adhesive layer 3, substrate 4, coating 5, and cover film 6 are stacked on top of the base film 2 in sequence. The outer frame 1 is mainly used for protection during transportation. There is a gap between the outer frame 1 and the base film 2, adhesive layer 3, substrate 4, coating 5, and cover film 6 to facilitate separation between them. The limiting blocks 11 are located inside the grooves 61 and sequentially limit the base film 2, adhesive layer 3, substrate 4, coating 5, and cover film 6, increasing the stability of the base film 2, adhesive layer 3, substrate 4, coating 5, and cover film 6 inside the outer frame 1 and reducing shaking.
[0028] More specifically, the interior of the substrate 4 has two symmetrically arranged dotted grooves 41. The two dotted grooves 41 extend away from the side of the second patch 42. One side of the two dotted grooves 41 is connected to the interior of the groove 61. When the substrate 4 is glued to the opening of the box, if the substrate 4 is to be torn apart, the worker will pick up the second patch 42 and pull it upwards. When it is pulled to the dotted groove 41 inside the groove 61, the dotted groove 41 will tear to one side of the substrate 4. The substrate 4 can be torn apart at the interface of the box. The torn substrate 4 can prevent the label from being reused, reduce the problem of reuse after the box is separated, and increase the safety of the product.
[0029] Furthermore, during implementation, the upper surfaces of the outer frame 1 and the limiting block 11 are kept consistent, the upper part of the limiting block 11 is attached to the lower part of the protective film 7, and the upper surfaces of the outer frame 1, the limiting block 11 and the covering film 6 are protected by the protective film 7, reducing the corrosion of the outer frame 1, the limiting block 11 and the covering film 6 by the air, and increasing the safety during use.
[0030] The working principle of the waterproof self-adhesive label provided by this utility model is as follows:
[0031] When using the self-adhesive label, the worker first picks up the outer frame 1, turns it inside out, and then peels off the bottom film 2, exposing the adhesive layer 3 to the air. The adhesive layer 3 is then placed at the opening of the box, covering the opening and firmly adhering the substrate 4 to it. The worker then peels off the outer frame 1, separating it from the protective film 7 and the covering film 6. With the substrate 4 firmly bonded to the box, it supports the coating 5, and the surface of the coating 5... Product information can be printed on it, which can enhance the promotional ability of self-adhesive labels. The upper surface of coating 5 is protected by a covering film 6. The covering film 6 is made of highly transparent and wear-resistant material, which can not affect the information on the surface of coating 5, while increasing the security of the information on the surface of coating 5, reducing water and fire damage, and increasing service life. Through the protection of the base film 2 and the protective film 7, the substrate 4 and coating 5 can be protected, increasing safety during transportation. The covering film 6 can protect the substrate 4 and coating 5 during use, increasing wear resistance and safety, and increasing service life.
[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
