Patent number: 9173814Abstract: The present invention relates to a container for liquids, a method of filling it and the use of the container according to the invention for holding and storing radioactive substances. The container for a liquid comprises a cavity for holding the liquid, the cavity being bounded by walls (1) at the sides and at the bottom, an opening for filling the cavity with the liquid, a closure for closing off the cavity, the closure having a piercing region for inserting a cannula into the cavity, a bottom casing (20) which surrounds the walls of the cavity in the standing area, a top casing (10) which surrounds the pierceable closure with the exception of the piercing region, and a film (30) which extends from the top casing to the bottom casing and surrounds those areas of the walls of the cavity which are not already surrounded by the top casing or bottom casing.Type: GrantFiled: July 12, 2012Date of Patent: November 3, 2015Assignee: Algeta ASAInventors: Jan Børge Jakobsen, Peer Børreetzen, Bjørn Haugseter
