Abstract: An active ingredient cartridge (2) for a medical syringe (1) with an essentially cylindrical hollow body (16) made of a first plastic material that can be filled with an active ingredient is intended to facilitate filling of the active ingredient and also to enable high throughput rates during filling in automated processes. For this purpose, according to the invention, the hollow body (16) is provided at one end (4) with an integrated closure body (50) made of a second plastic material which is softer than the first, wherein the hybrid body formed by the hollow body (16) and the closure body (50) is obtained by a 2K injection molding process.

Abstract: A closure system for a medication container, the interior of which is accessible via a container opening designed in the manner of a bottle mouth, comprising a bump cap with an annular lid having a central opening, on the outer circumference of which is arranged a number of latching elements which can be brought into engagement with an outer bead mounted circumferentially on the container opening, and a one-piece closure plug with a closure body which completely fills the central opening of the annular lid and can be brought into latching engagement therewith, is intended to enable continuous compliance with even high sterility requirements during handling in a simple and reliable manner. For this purpose, the closure body is designed as a duckbill valve.

Abstract: A closure cap (2, 2?) for a syringe body (40, 40?) prefilled with a medicament or medical active substance is intended to reliably ensure a high degree of leak-tightness with simple handling. For this purpose, the closure cap (2, 2?) according to the invention comprises a rigid carrier cap (6, 6?) provided with an external thread (18) in a contact region (16), which has an inner channel (14) extending in a longitudinal direction, in which a sealing plug (8, 8?) made of a softer and more deformable material than the carrier cap (6, 6?), preferably made of rubber or TPE, is arranged.
