The body (40) defines a dispensing opening (92, 92A) and a sealing surface (94, 94A) around the dispensing opening (92, 92A). A lid (30, 30A) is provided for movement between open and closed positions. The lid (30, 30A) has a frame defining a lid dispensing passage (116, 116A) through the lid (30, 30A). The lid (30, 30A) includes a flexible valve (80, 80A) that is disposed within the lid frame across the lid dispensing passage (116, 116A). The flexible valve (80, 80A) has self-sealing slits (266) which open to permit flow therethrough in response to increased pressure on the side of the valve (80, 80A) facing the container (22) when the lid (30, 30A) is closed.</p> |
