Abstract

A fluid dispensing nozzle construction, bellows-like tube therefor and methods of making the same are provided, the construction comprising a valve body having a dispensing spout extending therefrom, and a flexible bellows-like tube of polymeric material telescopically disposed on the spout and having opposed ends one of which is secured to the valve body and the other of which carries a face seal for engaging an annular lip of fill pipe of a fluid storage tank to seal around an opening in the fill pipe when the spout is inserted therein, the spout having an abutment for interlocking with an abutment of the fill pipe that is adjacent the opening thereof when the spout has been inserted into the opening a certain amount. The bellows-like tube has an annular convolution adjacent the face seal that has a larger cross-sectional thickness on one side thereof than the cross-sectional thickness on the other side thereof so that the convolution will tend to collapse at the other side thereof to maintain the seal on the lip around the opening when the spout has the abutment thereof interlocking with the abutment of the fill pipe.
