WIPO Patent Application WO/2022/166986

A1

A sealed moisture-proof package capable of achieving free exchange of internal gas, and a packaging process. Two cavities, i.e. a first cavity (110) and a second cavity (120), are arranged in a packaging housing (100), and the separation between the two cavities, i.e. the first cavity and the second cavity is formed by means of an air-permeable bacteria-resistant layer (130); after a product is placed into an inlet (111) at the upper end of the first cavity, the inlet at the upper end of the first cavity can be sealed, and a sterilization operation is performed on the interior of the first cavity; furthermore, a drying agent can also be placed in the second cavity, which can ensure that the interior of the second cavity and the interior of the first cavity which is air-permeable and moisture-permeable to the second cavity are always in a dry state; and finally, the product is taken out from an outlet (112) at the lower end of the first cavity for use, so that the drying agent does not fall into a surgical tray, thereby improving the safety and hygiene of a surgical operation.
