Abstract
A valve assembly to dispense fluid from fluid containers including a member that is rotatably slideable in a tube between open and closed positions. The valve assembly utilizes sealing beads to provide seals so that fluid cannot be dispensed from the assembly when the assembly is in the closed position. The valve assembly also includes a tamper evident indicator to show a user whether or not the valve assembly has been previously actuated. The tamper evident indicator may include a tab that is broken when the valve assembly is first actuated. The tamper evident indicator may also include a skirt that either detaches from a knob or fractures when the valve assembly is first actuated.
