Abstract
A collapsible medical agent container (10) is disclosed having walls (34, 36, 38) defining a plurality of chambers (12, 14) for containing selected quantities of one or more medical fluids or a dry or encapsulated drug or other reagent in separate sealed condition. Opening means which communicates between adjacent chambers (12, 14) for passage of fluid from one chamber to another, is normally closed by frangible closure (18) which maintains the chambers (12, 14) in separate hermetically sealed condition until flow between the chambers (12, 14) is needed. The frangible closure (18) has an elongated relatively rigid portion (20) which extends into one of the chambers and is disposed within a protective retentive tube (24), and a relatively weakened portion (22) adjacent the opening means. The closure (18) is manually openable from exterior the container (10) to permit flow between the chambers (12, 14), such as for mixing, by grasping the elongated portion (20) through the walls (30, 32) of the container (10) and bending it until the relatively weakened portion (22) is fractured.
