A dispensing valve for a resiliently deformable container includes a flange diaphragm having a sealing surface abutting a seating surface surrounding a dispensing opening in the cap. The flange diaphragm is retained against the seating surface at specific points, leaving portions of the flange diaphragm free to deform away from the seating surface. Thus, after the dispensing operation as the walls of the container try to return to their rest position, air can ingress into the container through the dispensing opening by forcing portions of the flange diap...
A dispensing valve for a resilient deformable container having a rest position and a deformed dispensing position, comprising an outlet for permitting an egress of fluid from the container when the container is deformed under pressure, and venting means for permitting an ingress of air into the container when the pressure is removed, comprising a resilient flange surrounding the outlet and having an opening in fluid communication with the outlet when the container is in the deformed dispensing position, a resilient sealing surface of the flange abutting ...
