Description

Technical Field

[0001] The utility model relates to the field of self-adhesive labels, in particular to a heat-sensitive paper self-adhesive label with anti-warping edges. Background Art

[0002] Anti-warping thermal paper self-adhesive label is a special type of label, which uses thermal paper as the material and has the characteristic of preventing edge warping. This kind of label does not need to use carbon ribbon when printing, but prints the information directly on the label through the thermal print head. At the same time, it adopts self-adhesive design and can be easily pasted on various items. The anti-warping feature makes it difficult for the edge of this label to warp after pasting, thus maintaining the neatness and flatness of the label;

[0003] A Chinese patent with publication number CN219759055U discloses a multi-layer structure of a thermal paper self-adhesive label, including a carrier paper, a first adhesive layer is fixedly installed on the bottom end of the carrier paper, an isolation layer is adhered to the bottom end of the first adhesive layer, a base paper is fixedly installed on the bottom of the isolation layer, a marking paper is fixedly installed on the top end of the carrier paper, a second adhesive layer is adhered to the top of the marking paper, and a thermal paper is adhered to the top of the second adhesive layer. The isolation layer can prevent the hot melt adhesive layer from melting and overflowing at high temperature, so that the carrier paper and the marking paper are always kept fixed; the waterproof glue inside the honeycomb hole can greatly improve the waterproof performance of the carrier paper, and effectively avoid the problem of the carrier paper being weakened and damaged when immersed in water.

[0004] The thermal paper self-adhesive label of the above patent is adhered to the surface of the release layer before use. When the label is pulled and removed by hand, the edge of the adhesive label is easily lifted up, and the adhesive materials stick to each other after lifting up, thus affecting subsequent use. The sticking makes it impossible to restore it later. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to solve the problem in the prior art that the thermal paper self-adhesive label is adhered to the surface of the release layer before use, and when the label is pulled and removed by hand, the edge of the adhesive label is easily lifted up, and the adhesive materials stick to each other after lifting up, thus affecting the subsequent use, and the subsequent restoration cannot be restored due to the sticking, this embodiment provides the following technical solutions:

[0028] A heat-sensitive paper self-adhesive label with an anti-warping edge, comprising a heat-sensitive material 1, such as Figure 1 and Figure 2 As shown, the heat-sensitive material 1 is the top layer of the label, and contains compounds that can change color due to temperature changes. These compounds are usually hidden colors and will only show color when heated. A paper substrate 3 is arranged at the lower end of the heat-sensitive material 1, and the paper substrate 3 is ordinary paper, which supports the heat-sensitive material 1 and provides overall strength and structure;

[0029] In this embodiment, if Figure 1 and Figure 2 As shown, an adhesive 6 is provided at the lower end of the paper substrate 3, and the entire label is adhered to the bonding position by the adhesive 6. This layer of adhesive 6 allows the label to be attached to various surfaces, and the bonding thereby realizes the fixing function of the label;

[0030] In this embodiment, sponge protection sheets 2 are arranged at the four corners of the heat-sensitive material 1, the paper substrate 3 and the adhesive 6. The sponge protection sheets 2 are made of plastic sponge. The sponge protection sheets 2 wrap and protect the heat-sensitive material 1, the paper substrate 3 and the adhesive 6. Figure 1 and Figure 2 As shown, the surroundings are prevented from bulging and thus easily warping up. On the other hand, the sponge protective sheet 2 made of sponge material is relatively soft, and the user can use the fingernail to press it, which makes it easy to remove the label from the upper end of the adhesive layer 5, and the pressing will not cause the surroundings of the label to warp up. The four sponge protective sheets 2 are provided with grooves 4 on the outside facing the surroundings, and the grooves 4 extend to the inside of the sponge protective sheet 2. The concave grooves 4 can facilitate the user's fingers to insert and warp the entire label, forcing the label to separate from the surface of the adhesive layer 5.

[0031] In this embodiment, the front and rear ends of the paper substrate 3 facing the heat-sensitive material 1 are both provided with a first lower mounting cavity 13, and the front and rear ends of the heat-sensitive material 1 facing the paper substrate 3 are both provided with a first upper mounting cavity 12. Figure 2 and Figure 5As shown, three first upper mounting cavities 12 and three first lower mounting cavities 13 are sequentially arranged in the transverse direction, and a first support bar 7 is arranged between each of the first lower mounting cavity 13 and the first upper mounting cavity 12. The first support bar 7 is filled between the heat-sensitive material 1 and the paper substrate 3 to avoid wrinkles around the label, and to avoid warping around the label when the label is attached and removed from the upper end of the adhesive layer 5. The upper and lower ends of the first support bar 7 are respectively fixed to the contacted heat-sensitive material 1 and the paper substrate 3 by glue;

[0032] In this embodiment, the second lower mounting cavity 15 is disposed on both sides of the paper substrate 3 facing the heat-sensitive material 1, and the second upper mounting cavity 14 is disposed on both sides of the heat-sensitive material 1 facing the paper substrate 3. Figure 3 , Figure 4 and Figure 6 As shown, two second upper mounting cavities 14 and second lower mounting cavities 15 are transversely arranged, and a second support bar 8 is arranged between the second upper mounting cavity 14 and the second lower mounting cavity 15. The second support bar 8 is filled between the heat-sensitive material 1 and the paper substrate 3 to avoid wrinkles around the label, and warping around the label when the label is attached and removed from the upper end of the adhesive layer 5. With the support of the first support bar 7 and the second support bar 8, when the user grabs the label and makes the label shake in the air, the label will not be folded or deformed after being supported by the second support bar 8 and the first support bar 7, thereby improving the stability of the label when in use, and at the same time, the edge position also avoids warping around the label, and the upper and lower ends of the second support bar 8 are respectively fixed to the contacting heat-sensitive material 1 and the paper substrate 3 by glue;

[0033] In this embodiment, if Figure 3 As shown, an adhesive layer 5 is provided at the lower end of the adhesive 6. When the adhesive layer 5 is stored in a roll or sheet form, in order to prevent the labels from sticking to each other, a layer of release paper or release film is usually covered on the surface of the adhesive layer 5. This layer of material has anti-sticking properties and can be easily peeled off without damaging the adhesive layer. The addition of the adhesive layer 5 can facilitate the transportation and use of the label.

[0034] In this embodiment, the lower end of the adhesive layer 5 is provided with an anti-folding block 9, and the anti-folding block 9 is adhered to the lower end of the adhesive layer 5. Figure 3 As shown, the anti-folding block 9 is cross-combined by a first anti-folding strip 10 and a second anti-folding strip 11. The cross-combined anti-folding block 9 can serve as a support for the lower end of the adhesive layer 5 to prevent the adhesive layer 5 from being deformed and bent. The anti-folding block 9 provides support while preventing bending, so that when the label as a whole is wrapped around the outside of the roll, the support of the anti-folding block 9 can avoid contact between adjacent adhesives 6, thereby preventing contact from affecting subsequent separation and improving convenience during use.

[0035] Working principle: when using the label and removing it from the surface of the adhesive layer 5, the user's finger is embedded in the groove 4 position reserved inside the sponge protective sheet 2. The label can be removed by pressing the groove 4 position, and the label is removed. During the removal process, the surrounding of the label is supported by the first support bar 7 and the second support bar 8 located inside. The support prevents the label from folding due to shaking and blowing, and prevents the adhesive layers 5 from contacting each other due to folding, and prevents sticking caused by contact. The support avoids affecting subsequent use. After the label is successfully attached to the adhesive position by the adhesive layer 5, the sponge protective sheet 2 is used to support the label at the four corners of the label to prevent the label from curling up during use, and also to prevent the label from curling up and being unable to recover when separated from the adhesive layer 5.
