CONTAINER AND CLOSURE WITH DISPENSING VALVE AND SEPARATE RELEASABLE INTERNAL SHIPPING SEAL

摘要

A dispensing system (30) is provided for a container (42) having an opening (41) to the interior. The container (42) has a sealable seat (48) around the opening (41) and a thread (46). A closure (40) is disposed on the container (42). The closure (40) defines a thread (114) that is threadingly engaged with the container thread (46) for accommodating movement of the closure (40) between a lowered position and an elevated position. The closure (40) defines a dispensing passage (104) for establishing communication between the container opening (41) and the exterior of the closure (40). The closure (40) includes a dispensing valve (80) disposed in the dispensing passage (104) for opening to dispense fluid therethrough and for closing to occlude flow. The closure (40) includes an occlusion member (140) inwardly of the valve (80) in the dispensing passage (104) to sealingly engage the container seat (48) and prevent flow from the container opening (41) into the dispensing passage (104) below the valve (80) when the closure (40) is in the lowered position and to permit flow into the dispensing passage (104) when the closure (40) is in the elevated position.
