Description

Technical Field

[0001] This utility model relates to the field of sealing gaskets, and in particular to an electromagnetic induction sealing gasket and a multi-purpose integrated sheet. Background Technology

[0002] To prevent counterfeiting and ensure traceability, some people attach information tags by looping them around the neck of the product container or directly affixing them to the middle area. However, both methods of labeling result in the tags being easily removed or torn off for reuse. Even worse, some criminals remove or tear off the tags and reattach them to other product containers, rendering the anti-counterfeiting features ineffective. Furthermore, these existing labeling methods may place the tags too close to the liquid contents inside the container, causing the wireless signal interacting with the tag to be absorbed by the liquid, significantly reducing the transmission distance and affecting wireless communication performance.

[0003] Furthermore, electromagnetic induction sealing gaskets work by heating the aluminum foil layer of the gasket through electromagnetic induction. This heat melts the lower layer of the gasket that contacts the bottle opening, causing it to adhere to the bottle and seal the container. For anti-counterfeiting and traceability purposes, some electromagnetic induction sealing gaskets incorporate an information layer. This information layer contains an RFID chip and an RFID antenna. The RFID chip can store various product information, such as production and transportation details, facilitating traceability and anti-counterfeiting measures.

[0004] However, existing electromagnetic induction sealing gaskets with information layers have the following problems:

[0005] 1. Since the information layer is an independent layer, this increases the thickness of the electromagnetic induction sealing gasket, and also causes problems of material waste, energy waste and labor waste;

[0006] 2. In addition, the aluminum foil layer is a single sheet structure, which can interfere with the information layer and even cause a significant degradation in the wireless communication performance of the radio frequency chip;

[0007] 3. Since the aluminum foil layer is a single sheet, electromagnetic induction heating will cause the lower layer below the aluminum foil layer to be heated as a whole. Since the lower layer mostly contains plastic components, when the lower layer is heated as a whole, some odorous gases will be produced. The odorous gases will seep into the contents of the container and cause people to feel uncomfortable.

[0008] In view of the above problems, it is necessary to study an electromagnetic induction sealing gasket and a multi-purpose integrated plate. The multi-purpose integrated plate integrates electromagnetic induction heating and information interaction functions, which helps to reduce the thickness of the electromagnetic induction sealing gasket, reduce material waste, consume less energy, have good wireless communication performance, and reduce the generation of odorous gases.

[0017] The second adhesive layer is a composite adhesive with a thickness of 0.5µm to 7µm. The second adhesive layer ensures that the peel strength between the protective layer and the multi-purpose component is greater than 4N / 15mm.

[0018] The protective layer is at least one of PE, PET, PEN, PA, PVDC, EVOH, PI, and PP layers; the thickness of the protective layer is 12µm to 100µm.

[0019] The wireless information chip is a radio frequency identification (RFI) near-field communication chip, an RFI high-frequency chip, an RFI ultra-high-frequency chip, or an RFI microwave chip.

[0020] The multi-purpose integrated chip has a ring tangent line with multiple breakpoints. The ring tangent line is located between the antenna and the electromagnetic induction heating part and surrounds the antenna.

[0021] The material of the electromagnetic induction heating part of the metal layer is aluminum, copper, gold, silver or tin, and the thickness of the metal layer is 6µm to 40µm.

[0022] The antenna with the metal layer is made of aluminum, copper, gold, silver or tin, and the thickness of the metal layer is 6µm to 40µm.

[0023] The substrate layer is at least one of PE, PET, PEN, PC, PI and PP layers; the thickness of the substrate layer is 20µm to 150µm.

[0024] The first adhesive layer is a composite adhesive with a thickness of 0.5µm to 7µm. The first adhesive layer provides a peel strength greater than 4N / 15mm between the substrate layer and the metal layer.

[0025] The multi-purpose component also includes a battery; the battery is electrically connected to the wireless information chip.

[0026] The thickness of the multi-purpose component is 6µm to 2.5mm.

[0027] The thickness of the multi-purpose component is 6µm to 300µm.

[0028] An electromagnetic induction sealing gasket, comprising the multi-purpose integrated sheet as described above.

[0029] The electromagnetic induction sealing gasket further includes a lower layer composited with a multi-purpose integrated sheet; the lower layer includes at least one of the following: paper layer, PP layer, PE layer, PET layer, PA layer, PVDC layer, EVOH layer, PIB layer, EVA layer, EAA layer, EEA layer, EBA layer, EMMA layer, EMAA layer, EMAC layer, polyacrylate layer, acrylic copolymer layer, and polyurethane layer; the thickness of the lower layer is 3µm to 120µm.

[0030] The electromagnetic induction sealing gasket further includes an upper layer; the upper and lower layers are respectively laminated to both sides of the multi-purpose integrated sheet. The upper layer includes at least one of the following: paper layer, PP layer, PE layer, PET layer, PEN layer, PI layer, PA layer, EPE layer, EPS layer, EPP layer, wax layer, varnish layer, silicone oil layer, and polyurethane layer; the thickness of the upper layer is 12µm to 3mm.

[0031] With the above solution, the multi-purpose integrated sheet of this utility model includes a base layer, a first adhesive layer, and a multi-purpose component. The multi-purpose component includes a metal layer and a wireless information chip. The metal layer is attached to the base layer through the first adhesive layer. The metal layer has an antenna and an electromagnetic induction heating part arranged around the antenna. The electromagnetic induction heating part is separated from the antenna, and the antenna is electrically connected to the wireless information chip. The electromagnetic induction heating part enables electromagnetic induction heating, while the antenna and wireless information chip enable information exchange. As can be seen from the foregoing, the multi-purpose integrated sheet of this utility model integrates electromagnetic induction heating and information interaction functions. Furthermore, the electromagnetic induction heating part and the antenna are located on the same layer, resulting in a smaller thickness of the multi-purpose integrated sheet. Therefore, the multi-purpose integrated sheet of this utility model helps to reduce the thickness of the electromagnetic induction sealing gasket. Moreover, the electromagnetic induction heating part has a ring-shaped structure, which reduces material waste and minimizes energy consumption due to the smaller heating area.

[0032] Furthermore, the electromagnetic induction heating element of this invention is arranged around the antenna, which minimizes the obstruction of the antenna by the electromagnetic induction heating element. This results in minimal interference from the electromagnetic induction heating element when the wireless information chip is conducting wireless communication, ensuring the wireless communication performance of the wireless information chip and helping to improve the wireless communication distance of the wireless information chip.

[0033] In addition, the electromagnetic induction heating part of this utility model is arranged around the antenna. In this way, when the electromagnetic induction heating part generates heat through electromagnetic induction, it will only stick the lower periphery of the electromagnetic induction sealing gasket to the container opening. This reduces the heating area of ​​the lower layer, reduces energy consumption, and avoids the lower layer from being overheated and generating some odorous gas. This prevents odorous gas from seeping into the contents of the container and causing discomfort. Attached Figure Description

[0059] like Figures 1 to 8As shown, this utility model discloses an electromagnetic induction sealing gasket, which includes a multi-purpose integrated sheet A and a lower layer B composited with the multi-purpose integrated sheet A. The multi-purpose integrated sheet A integrates electromagnetic induction heating and information interaction functions and has a small thickness, which helps to reduce the thickness of the electromagnetic induction sealing gasket.

This design reduces the amount of material used in the metal layer 1, thus lowering costs. Furthermore, the electromagnetic induction heating element 12 generates heat through electromagnetic induction to bond the lower layer B of the electromagnetic induction sealing gasket to the container opening. Since the electromagnetic induction heating element 12 surrounds the antenna 11, it minimizes obstruction of the antenna 11, resulting in minimal interference to the wireless information chip 2 during wireless communication.

Additionally, the surrounding arrangement of the electromagnetic induction heating element 12 ensures that when generating heat through electromagnetic induction, it only bonds the periphery of the lower layer B of the electromagnetic induction sealing gasket to the container opening, reducing the heated area of ​​the lower layer B. This prevents excessive heating of the lower layer B and the generation of odorous gases, thus avoiding odorous gases from seeping into the contents of the container and causing discomfort.

The antenna 11, the electromagnetic induction heating part 12, and the physical connecting bridge 13 of the metal layer 1 can be integrally arranged. The material of the physical connecting bridge 13 is aluminum, copper, gold, silver, or tin. The length of the physical connecting bridge 13 is 0.1mm to 3mm, and the width of the physical connecting bridge is 0.01mm to 5mm. Because the physical connecting bridge 13 is very small, it can block the heat conduction of the electromagnetic induction heating part 12 to the antenna 11 to the vast majority of the time, and only slightly reduces the wireless communication distance.
