Abstract: A closure mechanism for a container said closure mechanism comprising a main body (2) either forming part of the container or adapted for attachment thereto. The mechanism has a plunger (3) movably mounted on the main body, and a dispenser (4) mounted on the main body for movement between a closed position and an open position. At the closed position a flow path for product within the container is obstructed and at the open position the product may be dispensed from the container through the flow path. The mechanism further comprising a mechanical linkage (25) that links the movement of the plunger (3) to the dispenser (4) such that the movement of one cause a movement of the other. The flow path is preferably formed within the dispenser, and the mechanical linkage is preferably a lever.
