Port closure system for intravenous fluid container

A port closure system for use with a fluid container having a fluid port, comprising:

• a reseal housing adapted to seal the fluid port in closed condition, the reseal housing having a base face adapted to be associated with the fluid port and an interior face adapted to face outwardly from the fluid port, an open cylinder extending from the interior face to the base face and having an upper rim, and a diaphragm connected to the open cylinder to seal the open cylinder closed to fluid flow;
• a cap assembly connected to the reseal housing, the cap assembly including an under shell shaped to mate with the interior face of the reseal housing to seal the interior face, a removable cap which provides access to a sealed opening located over the interior face, and a retaining rim extending from the under shell around the sealed opening;
• and
• a reseal element positioned between the under shell and the interior face of the reseal housing, the reseal element mechanically retained in place by the retaining rim and the upper rim of the open cylinder.

A reseal element for use with a fluid container having a fluid port, comprising:

• a central core adapted to provide resealable access to the fluid port;
• an annular shoulder extending radially from the central core;
• a lip element connected to the annular shoulder and extending transversely to the annular shoulder in two directions;
• and
• wherein the reseal element is adapted to be mechanically retained between the central core and the lip element.

A port closure system for use with a piercing pin and a fluid container having a fluid port, comprising:

• an administrative housing adapted to seal the fluid port in closed condition, the administrative housing having a base surface adapted to be associated with the fluid port and an interior surface adapted to face outwardly from the fluid port, a sleeve extending from the interior surface past the base surface, and a diaphragm connected to the sleeve to seal the sleeve against fluid flow;
• the sleeve having an upper portion and a lower portion, the upper portion being adjacent the interior surface and having an opening with a lesser diameter than the lower portion, and the diameter variation between the upper and lower portions permitting the sleeve to receive and sealably associate with the piercing pin during use regardless of the diameter of the piercing pin;
• and
• a cap assembly connected to the administrative housing, the cap assembly including an under shell shaped to mate with the interior surface of the administrative housing to seal the interior surface, and a removable cap which provides access to a sealed opening located over the sleeve.
