  • Patent number: 7543723
    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.

  • Publication number: 20070187409
    Abstract: Disclosed herein is an air-vented closure assembly for a fluid container. The closure assembly has a valve body and a valve element. The valve body has a first fluid conduit and a second fluid conduit spaced from the first conduit. The valve body has a mounting sleeve in fluid communication with the first fluid conduit and the second fluid conduit, the mounting sleeve having an axis therethrough. The valve member is positioned in the mounting sleeve for reciprocating movement therein from a closed position to an open position in response to rotation of the valve member about the axis. The valve member has a wall having a first end and an opposed second end, the valve member having a third fluid conduit therethrough. A first portion of the wall of the valve member is removed to define an air inlet into the third fluid conduit and a second portion is removed to define an air outlet from the third conduit.

  • Publication number: 20050230420
    Abstract: A flexible polymeric container for storing and dispensing liquids includes a first sidewall and a second sidewall connected together to define a fluid chamber therebetween. The first sidewall and the second sidewall each have an inner surface facing the fluid chamber and an opposed outer surface. A fitment is attached to an outer surface of one of the first sidewall or the second sidewall. The fitment has an opening therethrough which has an axis substantially perpendicular to the outer surface. A plurality of objects on the inner surface of one of the first sidewall or the second sidewall defines a plurality of pathways having at least a first pathway and a second pathway intersecting one another.
