Description

Technical Field

[0001] The utility model relates to the technical field of sleeping bag auxiliary equipment, in particular to a humidity-sensitive label, which is used to be attached to the surface of a sleeping bag and display when the humidity of the sleeping bag reaches a predetermined value. Background Art

[0002] Conventional thermo-hygrometers are often placed as individuals in the environment to detect the temperature and humidity of the environment. It is difficult to directly use them to detect the humidity of a sleeping bag. Not only is it difficult to attach or install, but it is also greatly affected by the external environment and difficult to accurately detect the humidity of the sleeping bag.

[0003] In addition, there are also some devices that detect and adjust the humidity of a sleeping bag through a chip, but the overall structure is relatively complex, the design cost is high, and it is difficult to manufacture and maintain. Summary of the Utility Model

[0004] An embodiment of the present application provides a humidity-sensitive label that can display very sensitively when the humidity of the sleeping bag reaches a set value, which is convenient for users to visually judge quickly, easy to manufacture, and low in cost.

[0005] An embodiment of the present application provides a humidity-sensitive label for attaching to the surface of a sleeping bag. The humidity-sensitive label is a layered structure, including a silicone film layer, a humidity-sensitive color-changing layer, and a humidity threshold layer stacked in sequence. The silicone film layer is a transparent structure, and the pore size of the silicone film layer is smaller than the size of water molecules. The silicone film layer completely covers the humidity-sensitive color-changing layer and the humidity threshold layer, and has a pasting part protruding from the humidity-sensitive color-changing layer and the humidity threshold layer to be able to paste on the surface of the sleeping bag. The humidity threshold layer completely covers the humidity-sensitive color-changing layer. When the humidity of the sleeping bag is greater than the threshold of the humidity threshold layer, the moisture in the sleeping bag can penetrate through the humidity threshold layer and soak into the humidity-sensitive color-changing layer, causing the humidity-sensitive color-changing layer to change color.

[0006] In a possible implementation, the thickness of the silicone film layer is 6 filaments - 25 filaments.

[0007] In a possible implementation, the humidity-sensitive label further includes a hot-melt adhesive layer, and the hot-melt adhesive layer is between the silicone film layer and the humidity-sensitive color-changing layer.

[0008] In a possible implementation, the humidity-sensitive color-changing layer is humidity-sensitive color-changing ink.

[0009] In a possible implementation, the humidity threshold layer is hydrogel ink.

[0010] In a possible implementation, the humidity-sensitive label further includes a PET positioning film, and the PET positioning film is attached to the outer surface of the silicone film layer.

[0011] In a possible implementation, a hot melt adhesive is provided on the inner surface of the pasting portion.

[0012] In a possible implementation, the pasting portions are evenly or symmetrically distributed on the outer periphery of the silica gel film layer, or the pasting portions completely cover the outer periphery of the silica gel film layer.

[0013] In a possible implementation, the humidity-sensitive label further includes a white ink coating, and the white ink coating is located on the side of the humidity threshold layer away from the humidity-sensitive color-changing layer.

[0014] In a possible implementation, the humidity-sensitive label further includes a micro-water film layer, the micro-water film layer is located on the side of the white ink coating away from the humidity threshold layer, the pore size of the micro-water film layer is larger than the size of water molecules and smaller than the pore size of the humidity-sensitive color-changing layer.

[0015] Beneficial effects: Compared with the prior art, the humidity-sensitive label provided by the present application can be directly attached to the surface of the sleeping bag. The silica gel film layer can effectively isolate the influence of external water vapor on the humidity-sensitive color-changing layer, and thus can ensure the accuracy of the humidity detection of the sleeping bag. When the humidity in the sleeping bag reaches the threshold set by the humidity threshold layer, the moisture in the sleeping bag penetrates through the humidity threshold layer and directly enters the humidity-sensitive color-changing layer, causing the humidity-sensitive color-changing layer to directly change color, and then being revealed through the transparent silica gel film layer. It is very convenient to use, and the humidity-sensitive label is easy to manufacture and form, and has a low cost.

[0021] Reference Figure 1 , an embodiment of the present application provides a humidity-sensitive label for attaching to the surface of a sleeping bag 90, which performs real-time visual display when the humidity of the sleeping bag 90 reaches a predetermined value for the user to quickly judge. The visual display is mainly color display. The humidity-sensitive label is a layered structure, including a silicone film layer 10, a humidity-sensitive color-changing layer 20, and a humidity threshold layer 30 stacked in sequence. The silicone film layer 10 is a transparent structure, and the pore size of the silicone film layer 10 is smaller than the size of water molecules, thereby playing a role in isolating external water vapor and avoiding the influence of the external environment on the inner humidity-sensitive color-changing layer 20, and further ensuring the accuracy of humidity detection of the sleeping bag 90. In addition, the silicone film layer 10 completely covers the humidity-sensitive color-changing layer 20 and the humidity threshold layer 30, and has a pasting portion 11 protruding from the humidity-sensitive color-changing layer 20 and the humidity threshold layer 30, so that the humidity-sensitive label can be directly pasted on the surface of the sleeping bag 90. The humidity threshold layer 30 completely covers the humidity-sensitive color-changing layer 20. When the humidity of the sleeping bag 90 is greater than the threshold value of the humidity threshold layer 30, the moisture in the sleeping bag 90 can penetrate through the humidity threshold layer 30 and soak into the humidity-sensitive color-changing layer 20, causing the humidity-sensitive color-changing layer 20 to change color, such as changing from blue to white, so that the user can quickly and intuitively discover the change in the humidity of the sleeping bag 90 and can quickly make a decision to provide a more comfortable and safe protection means for children.

[0022] The humidity-sensitive label provided by the present application has a simple structure, is easier to manufacture and form, has a low manufacturing cost, and is convenient to use.

[0023] In one embodiment, the thickness of the silicone film layer 10 is 6 silk - 25 silk, thereby ensuring that after the silicone film layer 10 is hot-pressed onto the sleeping bag 90, the sleeping bag 90 can still maintain its softness and comfortable wearing performance.

[0024] In one embodiment, the humidity-sensitive label further includes a hot-melt adhesive layer 40. The hot-melt adhesive layer 40 is located between the silica gel film layer 10 and the humidity-sensitive color-changing layer 20. It can be coated on the inner surface of the silica gel film layer 10 through a roll coating process. On the one hand, it can ensure that the silica gel film layer 10 is more conveniently hot-pressed onto the surface of the sleeping bag 90. On the other hand, it can also avoid the disadvantage that it is not easy to screen-print due to the smoothness of the silica gel film itself, so that the humidity-sensitive color-changing layer 20 can be more conveniently and evenly screen-printed onto the surface of the silica gel film layer 10.

[0025] In one embodiment, the humidity-sensitive color-changing layer 20 is humidity-sensitive color-changing ink, which can be directly screen-printed onto the surface of the hot-melt adhesive layer 40, and the operation is convenient.

[0026] Further preferably, the humidity threshold layer 30 is hydrogel ink, which can be directly screen-printed onto the surface of the humidity-sensitive color-changing layer 20. When the humidity of the sleeping bag 90 is greater than the threshold of the humidity threshold layer 30, moisture will penetrate through this coating and contact the humidity-sensitive color-changing layer 20 to cause color change, achieving the purpose of controllable color-changing humidity.

[0027] Considering the defect that the silica gel film is soft and not easy to accurately position, resulting in difficult accurate positioning in subsequent cutting and hot stamping, in one embodiment, the humidity-sensitive label further includes a PET positioning film 50, wherein the PET positioning film 50 is attached to the outer surface of the silica gel film layer 10. Thus, the PET positioning film 50 can play a role in supporting the silica gel film layer 10, enabling the humidity-sensitive label to be accurately cut and hot-stamped. At the same time, the PET positioning film 50 is also easy to separate from the silica gel film layer 10. After hot stamping, tearing off the PET positioning film 50 will not affect the softness and wearing comfort of the silica gel film layer 10 itself.

[0028] In one embodiment, a hot-melt adhesive is provided on the inner surface of the sticking part 11, so that the humidity-sensitive label can be better attached to the surface of the sleeping bag 90. Preferably, the hot-pressing temperature of the hot-melt adhesive is the same as the hot-pressing temperature of the back adhesive coated on the silica gel film itself, thereby achieving the consistency of the hot stamping process and improving the operability and stability of the product.

[0029] Further preferably, the sticking parts 11 are evenly or symmetrically distributed on the outer periphery of the silica gel film layer 10, or the sticking parts 11 completely cover the outer periphery of the silica gel film layer 10.

[0030] It is also worth mentioning that in order to avoid the sensory impact of the color of the fabric of the sleeping bag 90 on the color change of the humidity-sensitive color-changing layer, the humidity-sensitive label further includes a white ink coating 60, wherein the white ink coating 60 is located on the side of the humidity threshold layer 30 away from the humidity-sensitive color-changing layer 20, so that no matter what color the fabric the humidity-sensitive label is heat-pressed on, there is a white layer at the bottom for isolation, that is, the background color is equivalent to white, which can achieve the unity of the humidity-sensitive color change color and will not affect the color change effect due to different fabric colors.

[0031] In one embodiment, the humidity-sensitive label further includes a micro-water film layer 70. The micro-water film layer 70 is located on the side of the white ink coating 60 away from the humidity threshold layer 30. At the same time, the pore size of the micro-water film layer 70 is larger than the size of water molecules and smaller than the pore size of the humidity-sensitive color-changing layer 20. In this way, the micro-water film layer 70 not only does not affect the color-changing function of the humidity-sensitive color-changing layer 20, but also can effectively slow down the attenuation of the humidity-sensitive color-changing material during washing and extend the service life of the humidity-sensitive label.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
