Description

technical field [0001] The patent of the present invention relates to a sealing cover for a ceramic container and a manufacturing method thereof. Background technique [0002] At present, the containers generally used for packaging and storing food include glass and ceramics. Most of the glass containers are sealed with metal lids, while most of the ceramic containers are covered with ceramic lids and sealed with wax seals or rubber strips. This kind of sealing is not hygienic. , the airtightness is not good, and it is easy to cause its sealing failure during packaging and transportation, and it cannot be easily resealed after unsealing. Contents of the invention [0003] The object of the present invention is to provide a sealing cap capable of overcoming the defects of the above-mentioned ceramic container cap, and a method for making the ceramic sealing cap. [0004] In order to achieve the above object, the ceramic sealing cover (1) of the present invention is compose...
