Abstract
Abstract A container suitable for storing and dispensing parenteral fluids comprises a flat member 2 inserted into a pouch 1 of plastics material. The member has two ports 9, 10 passing therethrough which are protected by removeable tabs 14, 15 having passageways 19, 20 which are coaxial with the ports. The port 9 is sealed after filling by a cup-shaped closure (25, FIG. 4 not shown). The port 10 is closed by a ruptureable membrane and may have a resilient plug (29, FIG. 5 not shown) and needle guide (30, FIG. 5 not shown). The tabs may be connected to the member by portions 16, 16a, 17, 17a and 18 of reduced thickness. The outer ends of the passageways are sealed by covers 21, 22 or by flattening and sealing the ends of the passageways. The member, ports and tabs may be integrally formed by injection moulding (FIG. 1).

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
195 words
A container for parenteral liquids comprising a pouch comprising two sheets of medically-acceptable plastics material which are joined together along their edges and at one end thereof, a substantially flat member located between and joined to the said sheets at the other end of the pouch to enclose the interior of the container, said substantially flat member having two integrally-formed ports adapted to communicate between the interior of the pouch and the exterior of the container, the first of said ports being adapted to be sealed after the container has been filled by the insertion of a cup-shaped closure, the second of said ports having rupturable occluding means which prevent the passage of liquid from the interior of the pouch to the exterior of the container, removable portions integrally formed with the substantially flat member, said removable portions having passageways coaxial with the ports, frangible webs of reduced thickness between the removable portions and the remainder of the substantially flat member to facilitate the removal of the removable portions from the substantially flat member, the outermost ends of the passageways being adapted to be sealed after filling to protect the outermost ends of the ports.
