Description

Technical Field

[0001] This utility model relates to the field of label technology, and more specifically, to a self-adhesive label that prevents corner curling. Background Technology

[0002] A label is an additional information card or sign added to identify a product. It usually has an adhesive layer and a waste paper layer attached underneath. To use it, the main body of the label is peeled off from the waste paper layer and then stuck to the corresponding product.

[0003] Existing labels are usually bonded to the object using self-adhesive adhesive. However, when the surface of the object is uneven or has a certain curvature, the self-adhesive adhesive cannot fill the gap between the object and the label, thereby reducing the contact area and adhesion between the label and the object, which can lead to problems such as the label peeling off or falling off. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-curling self-adhesive label. The technical problem to be solved by the present invention is that when the surface of the object to be attached is uneven or has a certain curvature, the self-adhesive cannot fill the gap between the object and the label, thereby reducing the contact area and adhesive force between the label and the object, which leads to problems such as the label easily curling up and falling off.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-curling self-adhesive label includes an adhesive layer, a backing paper layer adhered to the bottom surface of the adhesive layer, an intermediate layer on the top surface of the adhesive layer, a primer layer coated on the top surface of the intermediate layer, a surface material layer adhered to the top surface of the primer layer, a square frame groove on the top surface of the intermediate layer, multiple capsules within the square frame groove, each capsule being filled with adhesive, multiple slots on the bottom wall of the square frame groove, multiple locking blocks on the top surface of the adhesive layer, and multiple through grooves on the top surface of the adhesive layer.

[0007] like Figure 1-3 As shown, the specific implementation method is as follows: by setting up a capsule, glue, card slot, and card block, the card block is locked in the card slot, thereby limiting the position of the intermediate layer. When the intermediate layer lifts, the card block and card slot can offset the lifting force of the intermediate layer, thereby reducing the lifting of the intermediate layer. At the same time, the capsule is broken by the compression of the intermediate layer and the adhesive layer, so that the glue fills the square frame slot and bonds and fixes the card block to the card slot. The glue can flow to the space between the adhesive layer and the object being attached through the channel, thereby filling the gap between the adhesive layer and the object being attached, increasing the contact area and adhesion between the adhesive layer and the object being attached, thereby effectively preventing the risk of label lifting or falling off.

[0008] In a preferred embodiment, the number of capsules is several, and the capsules are evenly distributed on the bottom wall of the square frame groove.

[0009] In a preferred embodiment, there are several card slots, and the several card slots are evenly distributed on the bottom wall of the square frame slot, and each card block is locked in the card slot corresponding to its position.

[0010] In a preferred embodiment, there are several through slots, and the through slots are evenly distributed on the top surface of the adhesive layer.

[0011] In a preferred embodiment, each capsule is made of gelatin.

[0012] In a preferred embodiment, each of the adhesive materials is acrylic adhesive.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a device comprising a capsule, adhesive, a slot, and a block. The block is positioned within the slot to limit the movement of the intermediate layer. When the intermediate layer begins to lift, the block and slot counteract the lifting force, reducing the lifting effect. Furthermore, the square frame slot, capsule, and adhesive allow the capsule to rupture and release adhesive when the intermediate layer is in close contact with the adhesive layer, covering the slot and block and increasing the bonding strength between them. The adhesive also passes through the slot, filling the gap between the adhesive layer and the object being adhered to, thus increasing the contact area and adhesion strength. This effectively prevents the label from lifting or falling off. Attached Figure Description

[0019] 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.

[0020] Reference Figure 1-3 An anti-curling self-adhesive label includes an adhesive layer 1, a backing paper layer 2 bonded to the bottom surface of the adhesive layer 1, an intermediate layer 3 on the top surface of the adhesive layer 1, a primer layer 4 coated on the top surface of the intermediate layer 3, a surface material layer 5 bonded to the top surface of the primer layer 4, a square frame groove 6 on the top surface of the intermediate layer 3, multiple capsules 8 inside the square frame groove 6, each capsule 8 being filled with adhesive, multiple slots 7 on the bottom wall of the square frame groove 6, multiple clips 9 on the top surface of the adhesive layer 1, and multiple through grooves 10 on the top surface of the adhesive layer 1.

[0021] It is worth noting that the backing paper layer 2 is used to protect the adhesive layer 1 from being contaminated before use. At the same time, the primer layer 4 makes the adhesive layer 1 and the surface material layer 5 adhere more tightly, and also prevents chemical reagents from penetrating from the bottom layer and soiling the label surface. The surface material layer 5 is used to carry the printed content.

[0022] like Figure 1-3 As shown, the specific implementation method is as follows: by setting up capsule 8, glue, card slot 7, and card block 9, the card block 9 is locked in the card slot 7, thereby limiting the intermediate layer 3. When the intermediate layer 3 lifts up, the card block 9 and card slot 7 can offset the lifting force of the intermediate layer 3, thereby reducing the lifting of the intermediate layer 3. At the same time, the capsule 8 is broken by the compression of the intermediate layer 3 and the adhesive layer 1, so that the glue fills the square frame slot 6 and bonds and fixes the card block 9 to the card slot 7. The glue can flow to the space between the adhesive layer 1 and the object through the through groove 10, thereby filling the gap between the adhesive layer 1 and the object, increasing the contact area and adhesion between the adhesive layer 1 and the object, thereby effectively preventing the risk of label lifting and falling off.

[0023] There is a number of capsules 8, and the capsules 8 are evenly distributed on the bottom wall of the square frame groove 6.

[0024] There are several slots 7, and the slots 7 are evenly distributed on the bottom wall of the square frame slot 6, and each card block 9 is locked in the corresponding slot 7.

[0025] There are several through grooves 10, and the several through grooves 10 are evenly distributed on the top surface of the adhesive layer 1.

[0026] Each capsule 8 is made of gelatin, which has good biocompatibility and biodegradability. It can rupture under certain pressure, and gelatin can be made into different thicknesses and strengths, adapting to different pressure requirements by adjusting the manufacturing process.

[0027] Each adhesive is made of acrylic, which has excellent bonding performance and weather resistance, and dries quickly, enabling labels to achieve high bonding strength in a short time and improving production efficiency.

[0028] In use, the backing paper layer 2 is first torn from the bottom of the adhesive layer 1. Then, the adhesive layer 1 is bonded to the surface of the object to be labeled. Once the position is determined, pressure is applied from the top surface of the surface material layer 5, so that the intermediate layer 3 and the adhesive layer 1 are tightly bonded. During the pressing process, the positions of the slots 7 and the blocks 9 correspond, so that each block 9 is locked in the corresponding slot 7. At the same time, the capsule 8 breaks, causing the glue inside the capsule 8 to flow out, thereby filling the square frame groove 6 and covering the slots 7 and blocks 9, thus firmly bonding the slots 7 and blocks 9. The glue flows out through the channel 10 towards the bottom of the adhesive layer 1, thereby filling the gap between the label and the object to be labeled, thereby increasing the contact area and adhesion between the adhesive layer 1 and the object to be labeled, thus effectively preventing the risk of the label lifting or falling off.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
