Abstract: A stopper for a container and an assembly of a stopper and a container wherein 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 sealing position of the stopper and a contact section 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 has a higher degree of hardness than the sealing body. Regions of a lateral surface of the insertion section in contact with an inner surface of a container wall are formed by outer surfaces of the sealing body in the region of the contact section.

Abstract: A stopper for a container has a jacket portion insertable into the container, wherein the jacket portion has a through-opening formed in an axial direction, wherein the stopper has at least two segments, wherein the respective segment has a free end, wherein a first portion of the free end of the respective segment forms a subregion of the jacket portion, and a second portion of the free end of the respective segment protrudes radially inward in relation to the jacket portion, wherein a third portion of the free end of the respective segment protrudes radially outward in relation to the jacket portion, wherein the second portions form a cover portion that can be pierced through in the axial direction and that closes the through-opening, wherein the third portions form a bearing portion of the stopper for bearing against a container edge of the container.

Abstract: 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.
