Abstract

The arrangement insures that liquids of a volatile nature are not dispensed, due to temperature variations, from plastic squeeze bottle 2, having dispensing tube or nozzle 3. Pin hole 4 is located in tube 3 above the liquid level 5. Thus the pressure above level 5 is maintained at atmospheric pressure through hole 4 and tube 3. The latter also includes a ball valve 6 which, in the position shown, leaves the pin hole 4 uncovered. Ball 7 is forced against hole 4 when the liquid in bottle 2 is passing out through nozzle 3. This prevents air from being entrained with the liquid being dispensed.
