Abstract
A bottle for spraying or dispensing liquids comprising a principal chamber, a siphon tube extending alongside the chamber and a separate trigger bulb connected to the top of the siphon tube. The siphon tube is also pinch molded so that a valve seat is formed therein. When the trigger bulb is decompressed, the liquid that is drawn up into the siphon tube cascades over into the trigger bulb. When the trigger bulb is fully primed, any pressure subsequently applied to the trigger bulb will cause the liquid to be sprayed out of the bottle.
