<p>A dispensing structure is provided for discharging the contents from the interior of a container (22). The structure includes a body (40) for extending from the container (22). The body (40) defines a dispensing opening (56) and a sealing surface (58) around the dispensing opening (56). A lid (30) is provided for movement between open and closed positions. The lid (30) has a frame defining a lid dispensing passage (72) through the lid (30). The lid (30) has a mounting flange (76) extending inwardly adjacent the dispensing passage (72), and the lid (30) has a valve (80) mounted to the lid flange (76) across the dispensing passage (72). The flexible valve (80) has self-sealing slits (84) which open to permit flow therethrough in response to increased pressure on the side of the valve (80) facing the container (22) when the lid (30) is closed. The valve (80) has a lower flange (108) which is below the lid flange (76) and which sealingly engages the body sealing surface (58) when the lid (30) is in the closed position.</p> |
