A container has a body with a body opening. A spout fitment base is positioned within the body opening. A spout has a threaded engagement with the spout fitment base for movement between a retracted position and an extended position. A cap has a removed condition disengaged from the body, spout fitment base, and spout. The cap has an installed condition having a threaded engagement with at least one of the body and spout base fitment.
