A formed, filled, and sealed flexible container is provided with an attached port assembly. The container is formed from film folded to define opposing sidewalls which are sealed to define a chamber for sterile fluid. A hollow, tubular port member is provided with a V-shaped saddle and is sealed to the bottom of the container. The film at the bottom of the container is received in the saddle. A unique shoulder is defined by the tubular port member. The film is sealed to the shoulder and to the saddle of the port member. A hollow penetrator element is slidably disposed within the port member and is movable between a retracted position and an advanced position to puncture the film whereby fluid can flow out of the container. Internal formations are provided to guide and to limit the movement of the penetrator element. The container film may be provided with a crease along the bottom of the container.

[ What is claimed is:] [1.]1. A port assembly for use with a flexible container formed from a film folded to define opposing sidewalls having portions sealed together to define a chamber, said port assembly comprising:a hollow tubular port member having a distal discharge end and a proximal inlet end, said port member defining an annular sealing shoulder adjacent said inlet end against which the exterior surface of said film can be heat sealed to define radially inwardly thereof a generally circular, pierceable diaphragm, said annular sealing shoulder including(a) a radially inner, generally planar, annular first surface; and(b) a radially outer, generally arcuate, annular second surface extending from said first surface, said second surface having a transverse cross section which in part defines an arc of a circle and said second surface defining an annular groove for receiving a portion of said film to be heat-sealed thereto; anda hollow penetrator element slidably disposed in said tubular port member for movement between a fully retracted position away from said inlet end and a fully advanced position adjacent said inlet end to puncture said film diaphragm whereby fluid can flow out of said chamber through said hollow penetrator element and said port member.
