STOPPER FOR A CONTAINER FOR USE IN FREEZE-DRYING PROCESSES, AND ASSEMBLY OF A STOPPER AND A CONTAINER

摘要

A stopper for a container for use in freeze-drying processes, and an assembly of a stopper and a container are provided. The stopper has an insertion section configured for insertion into the container. The insertion section has a sealing section for closing the container in a fluid-tight manner in a sealing position of the stopper and a contact section which adjoins the sealing section axially from a top surface in the direction of a bottom surface, for holding the stopper in a drying position of the stopper. The contact section has at least one passage opening for a gas exchange between an interior of the container and the surroundings of the container. The stopper has a sealing body and a main body connected together, wherein the main body consists of a material which has a higher degree of hardness than a material which makes up the sealing body. Regions of a lateral surface of the insertion section in contact with an inner surface of a container wall in the drying position and/or the sealing position, are formed by outer surfaces of the sealing body in the region of the contact section, wherein the main body is configured within the sealing body in the region of the contact section.
