Patent ID: 8034041

Claim:
A reseal element for use with a fluid container having a fluid port of a given internal diameter, comprising: a central core adapted to provide resealable access to the fluid port, the central core having a cylindrical upper portion, a cylindrical lower portion having an outer diameter greater than the given internal diameter of the fluid port, and a cylindrical central portion interconnecting the upper portion and the lower portion; an annular shoulder directly attached to and extending radially outward from the cylindrical central portion of the central core; a lip element connected to the annular shoulder and extending transversely to the annular shoulder in two opposite, axial directions; the upper portion of the central core extending upwardly beyond the annular shoulder and the lip element and thereby defining a raised top surface of the reseal element; the lower portion of the central core extending downwardly beyond the annular shoulder and the lip element; and wherein the reseal element is adapted to be mechanically retained by clamping engagement of the annular shoulder along an annular path disposed between the central core and the lip element and substantially all of the lower portion of the central core has the outer diameter greater than the given internal diameter of the fluid port and is thereby adapted to be securely press fitted within the given internal diameter of the fluid port.
