Description

Technical Field

[0001] This utility model relates to the field of printing consumables technology, specifically to thermal transfer labels. Background Technology

[0002] To prevent the printed information on the front of the label from fading or scratching, the surface of the printed information usually needs to be coated for protection, which improves its waterproof, scratch-resistant and corrosion-resistant properties.

[0003] In related technologies, after laminating the printed information, it is necessary to first separate the first release paper layer from the laminating layer, then cut part of the first release paper layer and the label paper, tear off the remaining part of the first release paper layer, and finally paste the laminated printed information to the area of ​​use. The user operation steps are complicated.

[0004] Therefore, there is an urgent need for thermal transfer labels to solve the problem that the existing technology requires separate steps after lamination, including separating part of the release paper layer from the lamination layer, cutting part of the release paper layer from the label paper, and separating the remaining release paper layer from the printed information, which leads to complicated operation steps. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a thermal transfer label to solve the technical problem in the prior art that the operation steps are complicated because after the lamination is completed, it is necessary to separate part of the release paper layer from the lamination layer, cut part of the release paper layer from the label paper, and separate the remaining part of the release paper layer from the printed information in sequence.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a heat transfer label, including:

[0008] At least one printing unit, the printing unit including a first release paper, a label layer and a laminating layer, the first release paper including a first region and a second region, a fold line forming between the first region and the second region, the label layer being stacked on the first release paper and disposed in the first region, the laminating layer being stacked on the first release paper and disposed in the second region, the laminating layer being folded along the fold line to cover and adhere to the label layer, the first region and the second region being disconnected along the fold line, capable of causing one of the first region and the second region to separate from the label layer or the laminating layer disposed thereon, and leaving the other of the first region and the second region remaining on the corresponding label layer or laminating layer.

[0009] In some embodiments, the fold line is located at the center line of the first release paper, the first region and the second region are connected by the fold line, and are symmetrically distributed horizontally or vertically along the fold line as the axis.

[0010] In some embodiments, the side of the label layer facing away from the first release paper is used to add printing information. The printing unit further includes a first adhesive layer, one side of which is bonded to the coating layer and the other side of which can be bonded to the label layer, so that the coating layer can cover and bond the label layer. The bonding strength between the first adhesive layer and the coating layer and the label layer satisfies the requirement that when the first region and the second region are separated along the fold line, the coating layer and the label layer are always attached together.

[0011] In some embodiments, the printing unit further includes a second adhesive layer disposed between the label layer and the first release paper. The two sides of the second adhesive layer are respectively bonded to the label layer and the first release paper, and the adhesive strength between the second adhesive layer and the first release paper is such that when the first region and the second region are separated along the fold line, the label layer can be separated from the first release paper.

[0012] In some embodiments, the printing unit further includes a third adhesive layer disposed between the coating layer and the first release paper. The two sides of the third adhesive layer are respectively bonded to the coating layer and the first release paper, and the bonding strength between the third adhesive layer and the first release paper is such that when the first region and the second region are separated along the fold line, the third adhesive layer always remains on the first release paper.

[0013] In some embodiments, the printing unit further includes a second release paper covering the first adhesive layer.

[0014] In some embodiments, the second release paper includes a first segment and a second segment, which are separated and can together cover all portions of the first adhesive layer.

[0015] In some embodiments, the second release paper is elongated, and the first segment and the second segment are separated along the length of the second release paper.

[0016] In some embodiments, the third adhesive layer is AB double-sided adhesive, and the adhesive strength between the third adhesive layer and the coating layer is less than the adhesive strength between the third adhesive layer and the first release paper, so that when the first release paper separates from the coating layer, the third adhesive layer separates from the coating layer along with the first release paper.

[0017] In some embodiments, the number of printing units in the thermal transfer label is multiple, and the thermal transfer label further includes connecting lines. The connecting lines are disposed between two adjacent printing units and connected to both adjacent printing units, so that the first or second regions of the multiple printing units are alternately arranged sequentially along the winding direction or the first or second regions of the multiple printing units are arranged side by side along a direction perpendicular to the winding direction.

[0018] In some embodiments, the connection strength between the connecting line and the two printing units is such that when the two printing units are disconnected along the connecting line, the first region and the second region remain connected.

[0019] Compared with the prior art, the beneficial effects of the thermal transfer label provided by this utility model include: at least one printing unit is provided on the printing paper, wherein the printing unit includes a first release paper, a label layer and a coating layer, a first region, a second region and a fold line are formed on the first release paper, the first region and the second region are distributed on both sides of the fold line, the label layer and the coating layer are respectively disposed in the first region and the second region, the coating layer can be folded along the fold line to cover and stick to the label layer, and the first region and the second region are separated along the fold line, which can drive one of the first region and the second region to separate from the label layer or coating layer disposed thereon, and leave the other of the first region and the second region on the corresponding label layer or coating layer. Compared to existing technologies, after folding the first and second regions of the first release paper, the laminating layer can be folded and laminated onto the label layer. When the first release paper is cut along the fold line to separate the first and second regions, the first release paper can be separated from the laminating layer or the label layer, while ensuring that the laminating layer still adheres to the label layer. This combines the two steps of separating part of the release paper layer from the laminating layer and cutting part of the release paper layer from the label paper, simplifying the operation and making it more convenient to use. It solves the technical problem in existing technologies where the operation steps are complicated because it is necessary to separate part of the release paper layer from the laminating layer, cut part of the release paper layer from the label paper, and separate the remaining part of the release paper layer from the printed information in sequence.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0046] To address the technical problem of complex operation steps caused by the need to sequentially separate part of the release paper layer from the coating layer 13, cut part of the release paper layer from the label paper, and separate the remaining part of the release paper layer from the printed information 14 after lamination, this utility model provides a thermal transfer label. This label enables the coating layer 13 to be folded and laminated onto the label layer 12 after the first region 111 and the second region 112 of the first release paper 11 are folded. Furthermore, when the first release paper 11 is cut along the fold line 113, separating the first region 111 and the second region 112, the first release paper 11 can be simultaneously separated from the coating layer 13 or the label layer 12, while ensuring that the coating layer 13 remains adhered to the label layer 12. This combines the two steps of separating part of the release paper layer from the coating layer 13 and cutting part of the release paper layer from the label paper, simplifying the operation and making it more convenient to use.

[0047] It should be noted that the thermal transfer label of this utility model is used in, but not limited to, the field of printing consumables technology. For ease of explanation, this utility model only uses the application of thermal transfer label in the field of printing consumables technology as an example. The principle of thermal transfer label in other types of equipment is essentially the same as that in the field of printing consumables technology, and will not be described in detail here.

[0048] Please see Figures 1 to 7 , Figure 1 , Figure 2 This is a schematic diagram of the structure of a heat transfer label in one embodiment of the present invention. The heat transfer label includes at least one printing unit 1. The printing unit 1 includes a first release paper 11, a label layer 12, and a coating layer 13. The first release paper 11 includes a first region 111 and a second region 112. A fold line 113 is formed between the first region 111 and the second region 112. The label layer 12 is stacked on the first release paper 11 and disposed in the first region 111. The coating layer 13 is stacked on the first release paper 11 and disposed in the second region 112. The coating layer 13 can be folded along the fold line 113 to cover and adhere to the label layer 12. The first region 111 and the second region 112 are separated along the fold line 113, which can cause one of the first region 111 and the second region 112 to separate from the label layer 12 or the coating layer 13 disposed thereon, and leave the other of the first region 111 and the second region 112 on the corresponding label layer 12 or the coating layer 13.

[0049] In this device, at least one printing unit 1 is provided on the printing paper. The printing unit 1 includes a first release paper 11, a label layer 12, and a laminating layer 13. A first region 111, a second region 112, and a fold line 113 are formed on the first release paper 11. The first region 111 and the second region 112 are distributed on both sides of the fold line 113. The label layer 12 and the laminating layer 13 are respectively disposed on the first region 111 and the second region 112. The laminating layer 13 can be folded along the fold line 113 to cover and stick to the label layer 12. The first region 111 and the second region 112 are separated along the fold line 113, which can cause one of the first region 111 and the second region 112 to separate from the laminating layer 13 or the label layer 12 disposed thereon, and leave the other of the first region 111 and the second region 112 on the corresponding laminating layer 13 or the label layer 12.

[0050] Compared to existing technologies, after folding the first region 111 and the second region 112 of the first release paper 11, the laminating layer 13 can be folded and laminated onto the label layer 12. When the first release paper 11 is cut along the fold line 113 and the first region 111 and the second region 112 are separated, the first release paper 11 can be separated from the laminating layer 13 or the label layer 12, while ensuring that the laminating layer 13 is still adhered to the label layer 12. This combines the two steps of separating part of the release paper layer from the laminating layer 13 and cutting part of the release paper layer from the label paper, simplifying the operation and making it more convenient to use. It can solve the technical problem in existing technologies where it is necessary to sequentially separate part of the release paper layer from the laminating layer 13, cut part of the release paper layer from the label paper, and separate the remaining part of the release paper layer from the printed information 14, which leads to complicated operation steps.

[0051] Furthermore, in this device, the label layer 12 or the film layer 13 can be respectively disposed on the first region 111 or the second region 112, that is, when the label layer 12 is disposed on the first region 111, the film layer 13 is disposed on the second region 112, or when the film layer 13 is disposed on the first region 111, the label layer 12 is disposed on the second region 112. Further details will not be elaborated here.

[0052] In this embodiment, as Figure 2 As shown, the fold line 113 is located at the center line of the first release paper 11. The first region 111 and the second region 112 are connected by the fold line 113 and are symmetrically distributed horizontally or vertically along the fold line 113 as the axis.

[0053] The fold line 113 connects the first region 111 and the second region 112, and also facilitates folding the first region 111 and the second region 112 to make it easier for the film layer 13 to cover the label layer 12, and also makes it easier for the user to separate the first region 111 and the second region 112.

[0054] Furthermore, such as Figure 1 As shown, the label layer 12 and the coating layer 13 are symmetrically distributed along the fold line 113, as follows: Figure 3 As shown, the label layer 12 and the coating layer 13 are symmetrically distributed along the fold line 113.

[0055] Furthermore, such as Figure 4 As shown, the length directions of the label layer 12 and the coating layer 13 can also be set to be consistent with the length direction of the winding of the printing unit 1, or as shown in the figure. Figure 5 As shown, the width direction of the label layer 12 and the film layer 13 is aligned with the length direction of the printing unit 1 winding.

[0056] In this embodiment, as Figure 2 As shown, the printing unit 1 also includes a first adhesive layer 15, a second adhesive layer 16, a third adhesive layer 17, and a second release paper 18.

[0057] The label layer 12 is used to add printed information 14 on the side opposite to the first release paper 11. The first adhesive layer 15 is bonded to the film layer 13 on one side and to the label layer 12 on the other side, so that the film layer 13 can cover and bond the printed information 14. The bonding strength between the first adhesive layer 15 and the film layer 13 or the printed information 14 layer is such that when the first region 111 and the second region 112 are separated along the fold line 113, the film layer 13 and the printed information 14 layer are always attached together.

[0058] The label layer 12 is attached to the side opposite to the first release paper 11 for attaching the printed information 14. The first adhesive layer 15 is connected to the film layer 13 to achieve adhesion between the film layer 13, the adhesive layer, the printed information 14 and the label layer 12, and to form a protective film for the printed information 14.

[0059] Furthermore, the bonding strength between the first adhesive layer 15 and the film layer 13 or the printed information 14 is such that when the first region 111 and the second region 112 are separated along the fold line 113, the film layer 13 and the label layer 12 are always attached together, thereby avoiding accidental separation after the film layer 13, adhesive layer, printed information 14 and label layer 12 are formed as a whole.

[0060] In one embodiment, please refer to Figure 2 The second adhesive layer 16 is disposed between the label layer 12 and the first release paper 11. Both sides of the second adhesive layer 16 are bonded to the label layer 12 and the first release paper 11 respectively. The bonding strength between the second adhesive layer 16 and the first release paper 11 is such that when the first region 111 and the second region 112 are separated along the fold line 113, the label layer 12 can be separated from the first release paper 11.

[0061] The second adhesive layer 16 is used to bond the first release paper 11 to the label layer 12.

[0062] Furthermore, the bonding strength between the second adhesive layer 16 and the first release paper 11 is such that when the first region 111 and the second region 112 are separated along the fold line 113, the label layer 12 can be separated from the first release paper 11, which is convenient for users to operate and simplifies the operation steps.

[0063] In one embodiment, both the first adhesive layer 15 and the second adhesive layer 16 are pressure-sensitive adhesives.

[0064] The pressure-sensitive adhesive of the first adhesive layer 15 is mainly used to connect the laminating layer 13 to the printed information 14 and the label layer 12 after the first release paper 11 is flipped and folded, so that the laminating layer 13 can protect the printed information 14 and the label layer 12. The pressure-sensitive adhesive of the second adhesive layer 16 is mainly used to adhere to a fixed installation position after the first release paper 11 is peeled off, such as on the product surface or wall.

[0065] Furthermore, the pressure-sensitive adhesive used here is a standard feature known to those skilled in the art, and will not be described in detail further.

[0066] In one embodiment, please refer to Figure 2 The third adhesive layer 17 is disposed between the film layer 13 and the first release paper 11. Both sides of the third adhesive layer 17 are bonded to the film layer 13 and the first release paper 11 respectively. The bonding strength between the third adhesive layer 17 and the first release paper 11 is such that when the first region 111 and the second region 112 are separated along the fold line 113, the third adhesive layer 17 always remains on the first release paper 11.

[0067] The third adhesive layer 17 is used to bond the first release paper 11 to the film layer 13.

[0068] Furthermore, the bonding strength between the third adhesive layer 17 and the first release paper 11 is such that when the first region 111 and the second region 112 are separated along the fold line 113, the third adhesive layer 17 always remains on the first release paper 11, which can prevent accidental separation between the film layer 13, the first adhesive layer 15, the printed information 14 and the label layer 12, and can also prevent the third adhesive layer 17 from remaining on the film layer 13.

[0069] In one embodiment, the third adhesive layer 17 is an AB double-sided adhesive, and the adhesive strength between the third adhesive layer 17 and the coating layer 13 is less than the adhesive strength between the third adhesive layer 17 and the first release paper 11, so that when the first release paper 11 separates from the coating layer 13, the third adhesive layer 17 separates from the coating layer 13 along with the first release paper 11.

[0070] The bonding strength between the third adhesive layer 17 and the coating layer 13 is less than the bonding strength between the third adhesive layer 17 and the first release paper 11, which is beneficial to peel the third adhesive layer 17 off the coating layer 13 when separating the first region 111 and the second region 112 of the first release paper 11 from the coating layer 13.

[0071] Furthermore, AB double-sided tape is a standard setup known to those skilled in the art, and will not be elaborated upon further.

[0072] In one embodiment, please refer to Figure 2 The second release paper 18 covers the first adhesive layer 15.

[0073] The second release paper 18 is used to protect the first adhesive layer 15 and prevent the first adhesive layer 15 from coming into contact with too much dust before use, which would weaken its adhesiveness.

[0074] In one embodiment, such as Figure 1 , Figure 6 As shown, the second release paper 18 includes a first segment 181 and a second segment 182. The first segment 181 and the second segment 182 are separated and can jointly cover all parts of the first adhesive layer 15.

[0075] The second release paper 18 is composed of a first segment 181 and a second segment 182, which are disconnected from each other. Alternatively, it can be understood that the first segment 181 and the second segment 182 are separated by a solid slit line. The first segment 181 and the second segment 182 together cover all parts of the first adhesive layer 15, which makes it convenient to separate the second release paper 18 from the first adhesive layer 15.

[0076] Furthermore, such as Figure 6 As shown, one end of the second release paper 18 may not cover the first adhesive layer 15, while the other end of the second release paper 18 may be completely attached to the first adhesive layer 15. That is, in this embodiment, the area of ​​the second release paper 18 is slightly smaller than the area of ​​the first adhesive layer 15, so that the second release paper 18 can be quickly torn off to detach from the first adhesive layer 15.

[0077] In one embodiment, the coating layer 13 is a transparent PET film.

[0078] The transparent PET film does not affect the visibility of the label layer 12. The PET film also has good heat resistance, cold resistance, corrosion resistance and oil resistance, which can provide stable protection for the label layer 12, so that the label layer 12 can be used for a long time. The PET film here is a conventional setting known to those skilled in the art, and will not be described in detail.

[0079] In one embodiment, such as Figure 7As shown, the second release paper 18 is elongated, and the first segment 181 and the second segment 182 are separated along the length of the second release paper 18.

[0080] The second release paper 18 is elongated, with the first segment 181 and the second segment 182 separated along the length of the second release paper 18. This prevents the tension generated when separating the first segment 181 or the second segment 182 from the first adhesive layer 15 from acting on the fold line 113, thereby reducing the impact of separating the first segment 181 or the second segment 182 from the first adhesive layer 15 on the connection between the first region 111 and the second region 112, and avoiding accidental separation of the first region 111 and the second region 112.

[0081] In this embodiment, as Figures 3 to 5 As shown, the number of printing units 1 in the thermal transfer label is multiple. The thermal transfer label also includes connecting lines 2. The connecting lines 2 are disposed between two adjacent printing units 1 and are connected to both adjacent printing units 1, so that the first area 111 or the second area 112 of the multiple printing units 1 are arranged alternately along the winding direction, or the first area 111 or the second area 112 of the multiple printing units 1 are arranged side by side along the direction perpendicular to the winding direction.

[0082] The two adjacent printing units 1 are connected by a connecting line 2 to achieve an easy-tear connection structure.

[0083] Furthermore, the first region 111 or the second region 112 of the multiple printing units 1 are arranged alternately in sequence along the winding direction, or the first region 111 or the second region 112 of the multiple printing units 1 are arranged side by side along the direction perpendicular to the winding direction.

[0084] Furthermore, multiple printing units 1 are sequentially connected and wound onto the roller 3 to form a complete thermal transfer label. This is a conventional setup known to those skilled in the art and will not be described in detail here.

[0085] In one embodiment, the connection strength between the connecting line 2 and the two printing units 1 is such that when the two printing units are disconnected along the connecting line 2, the first region 111 and the second region 112 remain connected.

[0086] The connection strength between the connecting line 2 and the two printing units 1 is such that when the two printing units are disconnected along the connecting line 2, the first region 111 and the second region 112 remain connected, which can prevent the first region 111 and the second region 112 of the first release paper 11 from accidentally separating when the printing unit 1 is pulled off the printing paper.

[0087] Furthermore, both the fold line 113 and the connecting line 2 are dashed disconnected. The fold line 113 and the connecting line 2 are conventional settings known to those skilled in the art, and will not be described in detail here.

[0088] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0089] At least one printing unit 1 is provided on the printing paper, wherein the printing unit 1 includes a first release paper 11, a label layer 12 and a coating layer 13. A first region 111, a second region 112 and a fold line 113 are formed on the first release paper 11. The first region 111 and the second region 112 are distributed on both sides of the fold line 113. The label layer 12 and the coating layer 13 are respectively disposed on the first region 111 and the second region 112. The coating layer 13 can be folded along the fold line 113 to cover and stick to the label layer 12. The first region 111 and the second region 112 are separated along the fold line 113, which can cause one of the first region 111 and the second region 112 to separate from the label layer 12 or the coating layer 13 disposed thereon, and leave the other of the first region 111 and the second region 112 on the corresponding label layer 12 or the coating layer 13. Compared to existing technologies, after the first region 111 and the second region 112 of the first release paper 11 are folded in half, the laminating layer 13 can be folded in half and laminated onto the label layer 12. When the first release paper 11 is cut along the fold line 113 and the first region 111 and the second region 112 are separated, the first release paper 11 can be separated from the laminating layer 13 or the label layer 12, while ensuring that the laminating layer 13 is still adhered to the label layer 12. This combines the two steps of separating part of the release paper layer from the laminating layer 13 and cutting part of the release paper layer from the label paper, simplifying the operation and making it more convenient to use.

[0090] In the specific working process of this utility model, the printing unit 1 is first divided by the connecting line 2. Then, the second release paper 18 is peeled off from the film layer 13. Next, the first release paper 11 is folded along the fold line 113, so that the film layer 13 is connected to the printed information 14 and the label layer 12 via the first adhesive layer 15. Finally, the first area 111 and the second area 112 of the first release paper 11 are separated. During the separation process, the first area 111 of the first release paper 11 can be separated from the label layer 112 after film application or the second area 112 can be separated from the film layer 113 after film application. This makes it easy to stick the printed and filmed label layer 12 onto the product, which simplifies the operation steps and makes it convenient to use.

[0091] This device, through the above structure, can solve the technical problem in the prior art that the operation steps are complicated because it is necessary to sequentially separate part of the release paper layer from the film layer 13, cut part of the release paper layer from the label paper, and separate the remaining part of the release paper layer from the printed information 14.

[0092] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
