The invention comprises a nestable-extendable apparatus for dispensing fluids from a container. The dispensing apparatus is nestable－i.e., capable of being collapsed or inverted into the container when not in use and extended or telescoped therefrom when needed to dispense fluid. The apparatus includes a selectively operable dispensing valve at the outboard end of a flexible, extendable, nestable member preferably of generally circular cross section and generally conical longitudinal section. The dispensing valve can be “nested”, or collapsed into the container by inverting the membrane within itself into the container, and can be “telescoped”or extended by manually pulling the valve and membrane into the extended position by means of a pull-out ring. The dispensing valve can be collapsed into an opening in the container wall. The dispensing valve of the preferred embodiment may be opened by pressing a button with the thumb. The valve is preferably biased to close automatically when thumb pressure is released.

An apparatus for dispensing fluid from a container which comprises a selectively-operable dispensing valve in fluid communication with the container, means defining a cavity of sufficient size to allow said dispensing valve to nest inside the cavity, means for mounting the dispensing apparatus to a wall of the container, a flexible-extendable member interconnecting said mounting means and said valve, and a pulling tab for selectively moving the dispensing valve between a nested position in said cavity and an extended position outwardly from said cavity, said pulling tab having a first end attached to the valve and a second end which is movable between a first position for pulling the valve and a second position for locking the valve, and locking means extending from the flexible-extendable member constructed and arranged to engage the pulling tab in its locking position when the valve is nested in the cavity.
