ABSTRACT:
A squeeze-type bottle of the type containing a liquid, a syphon tube extending within the liquid and a nozzle communicating with the syphon tube includes an anti-syphon device disposed between the syphon tube and the nozzle, whereby expulsion of the liquid due to a pressure differential between the inside and the outside of the bottle when the bottle is not being used is prevented. The anti-syphon device is such that the bottle may be used in an inverted position.
