发明名称 Dispensing structure which has a lid with a pressure-openable valve
摘要 A dispensing structure is provided for discharging the contents from the interior of a container. The structure includes a body for extending from the container. The body defines a dispensing opening and a sealing surface around the dispensing opening. A lid is provided for movement between open and closed positions. The lid has a frame defining a lid dispensing passage through the lid. The lid includes a flexible valve that is disposed within the lid frame across the lid dispensing passage. The flexible valve has self-sealing slits which open to permit flow therethrough in response to increased pressure on the side of the valve facing the container when the lid is closed.
