High viscosity fluid dispenser with replaceable fluid-containing bag and nozzle

摘要

A dispenser comprises an upper portion having an annular member depending therefrom and a bottom portion having a base and an upright post connected to the base. It also includes a flexible bag capable of containing fluid suspended from the upper portion and located inside the annular member. The flexible bag has a nozzle connected to it such that the flexible bag is closed except at the nozzle. The nozzle has a discharge orifice in fluid communication with the flexible bag. The upper portion telescopingly engages the bottom portion such that the upright post is located substantially aligned with the flexible bag. The upright post is sized to cause the flexible bag to invert when the upper portion and the bottom portion are pressed together. An openable closure closes the discharge orifice so that a fluid-containing flexible bag may be easily handled for replacement of the emptied flexible bag in the dispenser. A removable rigid cover connected to the upper portion provides a surface against which a user may conveniently press the upper portion downward with a palm of the hand. The rigid cover is removable from the upper portion to enable the flexible bag to be replaced.
