Abstract
The present invention is a discharge nozzle for flexible dispensing tubes containing paste-like or semi-liquid substances. It solves the problem of having to contact the discharge opening of the dispensing tube against a secondary surface to cut off the flow of substance. This is advantageous for eliminating the transfer of germs between the discharge opening of the dispensing tube and the secondary surface. Additionally, it solves the problem of eliminating unwanted accumulation of substance at the nozzle discharge, even when the dispensing tube is used in a repetitive manner, over a long period of time. The nozzle is small in size, has a symmetrical interior surface, and has a discharge portion formed at least partially from a material possessing a low coefficient of friction. This discharge portion has an elongated slit and is attached to a tubular neck. The elongated slit may be configured in the shape of an 'I' to form two displaceable tongues.
