ABSTRACT:
An improved liquid-dispensing nozzle and more specifically, an improved vapor recovery means for a nozzle comprising a vapor collector (such as a flexible bellows) surrounding a portion of the discharge spout in spaced relation thereto, one end of which is sealed to the upper portion of the spout; and at the other end of the vapor collector, a compressible cellular plastic material such as foamed plastic associated therewith. When the discharge spout is inserted into, e.g., an automobile fillpipe, the compressible cellular plastic material forms a vapor seal with the upper end of the fillpipe whereby the vapors escaping from the fillpipe are directed into the interior chamber formed between the exterior of the discharge spout and the inside of the vapor collector thereby minimizing the escape of vapors to the atmosphere. The vapors are then removed from this chamber. The compressible cellular plastic material is made from an acrylonitrile elastomer.
