ABSTRACT:
An air-vented closure assembly for a fluid container has a valve body and a valve element. The valve body has first and second fluid conduits. The valve body has a mounting sleeve in fluid communication with the first and second fluid conduits. A valve member is positioned in the mounting sleeve for reciprocating movement from a closed position to an open position. The valve member has a wall having opposed ends, the valve member having a third fluid conduit therethrough. A first portion of the wall is removed to define an air inlet into the third fluid conduit and a second portion is removed to define an air outlet. When the valve member is in the closed position fluid flow through the first and second conduits is prevented, and when in the open position fluid can flow through the first conduit and air can flow through the air outlet.
