Description

Technical Field

[0001] The invention relates to the field of sealing gaskets, in particular to an electromagnetic induction sealing gasket and a multi-purpose integrated sheet. Background Art

[0002] For anti-counterfeiting and traceability purposes, some people will hang the information tag on the neck of the product container with a rope or directly stick the information tag on the waist area of ​​the product container. However, both of these information tag settings have the problem that the information tag is easy to be removed or torn off and reused. What's worse, some lawless elements will remove or tear off the information tag and re-hang it or stick it on the container of other products for secondary use, resulting in poor anti-counterfeiting of the information tag. In addition, the two existing information tag settings may be too close to the liquid contents in the container, causing the wireless signal acting on the information tag to be absorbed by the liquid contents, which greatly reduces the transmission distance of the wireless signal and affects the wireless communication effect.

[0003] In addition, the electromagnetic induction sealing gasket uses electromagnetic induction to heat the aluminum foil layer of the electromagnetic induction sealing gasket, which in turn causes the lower layer of the electromagnetic induction sealing gasket in contact with the container mouth to melt, so that the lower layer adheres to the bottle mouth to achieve sealing of the container mouth. In order to prevent counterfeiting and traceability, some electromagnetic induction sealing gaskets will be sandwiched with an information layer with a radio frequency chip and a radio frequency antenna. The radio frequency chip can store various product information such as production information and transportation information, thereby facilitating traceability and anti-counterfeiting.

[0004] However, the existing electromagnetic induction sealing gasket with information layer has the following problems: 1. Since the information layer is an independent layer, the thickness of the electromagnetic induction sealing gasket is increased, and there are also problems of material waste, energy waste and labor waste; 2. In addition, the aluminum foil layer is a whole piece of structure, which will interfere with the information layer and even cause the wireless communication performance of the RF chip to be greatly attenuated; 3. Since the aluminum foil layer is a whole piece, the lower layer below the aluminum foil layer will be heated as a whole during electromagnetic induction heating. Most of the lower layer contains plastic components, which will produce some odorous gases when the lower layer is heated as a whole. The odorous gases will infiltrate into the contents of the container and make people uncomfortable.

[0005] In view of the existence of the above-mentioned problems, it is necessary to study an electromagnetic induction sealing gasket and a multi-purpose integrated sheet, which integrates the dual functions of electromagnetic induction heating and information interaction, helps to reduce the thickness of the electromagnetic induction sealing gasket, reduce material waste, consume less energy, have good wireless communication performance, and can reduce the generation of odorous gases.
