Dispensing structure which has a lid with a push-in mounted pressure-openable valve

A dispensing structure for discharging the contents from the interior of a container, said dispensing structure comprising:

• a body for extending from said container, said body defining a dispensing opening for establishing communication between the exterior and interior of said container, and said body having a sealing surface around said body dispensing opening;
• and
• a lid for accommodating movement between (1) a closed position over said body dispensing opening, and (2) an open position away from said closed position, said lid having a frame defining a lid dispensing passage through said lid, said lid frame having an annular mounting flange extending radially inwardly adjacent said lid dispensing passage, said lid including a flexible valve that is disposed within said lid frame across said lid dispensing passage and that has self-sealing slits which open to permit flow therethrough in response to increased pressure on the side of said valve facing said container when said lid is closed, said valve having a generally annular wall defining a generally annular groove which is open radially outwardly for receiving said lid mounting flange, said wall being (1) sufficiently flexible to temporarily deform as said wall is forced against said lid mounting flange to accommodate seating of said lid mounting flange in said groove, and (2) sufficiently resilient to accommodate the retention of said lid mounting flange in said groove by adjacent portions of said valve annular wall, said valve annular wall including a retention flange with one side engaging said lid mounting flange and with another side engaging said body sealing surface when said lid is in said closed position.
