The telescoping spout includes a base through which a flexible tube extends and a sleeve fixed to the distal end of the tube. The sleeve is frictionally received on the base and is moveable to a position remote from the base to extend the tube. The sleeve has an open end with a protrusion. A cap with a small aperture in its top surface is received on the sleeve. The cap is rotatable from a position where the sleeve protrusion seals the cap aperture to prevent all liquid flow to a position where the liquid flow rate through the spout is controlled by the location of the sleeve protrusion relative to the cap aperture. Flow rate control by rotating the cap can take place regardless of the extension of the tube. Removal of the cap permits liquid flow at the maximum flow rate.
A telescoping spout for a liquid container of the type having a mouth defined by a neck and a tube with an open distal end, said spout comprising a base adapted to be received on the container neck and through which said tube extends, a sleeve fixed to said distal end of said tube, said sleeve being adapted to be received on said base and being moveable to a position remote from said base, said sleeve having an axis, a tubular section and an externally threaded section and a cap adapted to be received on said tubular sleeve section, said cap having an internally threaded section cooperating with said externally threaded section of said sleeve such that said cap can be rotated relative to said sleeve to move said cap along said axis to control liquid flow rate through said spout, said tubular sleeve section having a distal end with a protrusion, said protrusion comprising a side wall inclined toward said axis, said cap comprising a surface with an aperture defined by a side wall generally parallel to said sleeve protrusion side wall, wherein rotation of said cap relative to said sleeve causes said sleeve protrusion to be received in said cap aperture such that said sleeve protrusion side wall and said cap aperture side wall engage along the length thereof to prevent fluid flow through the spout.
