ANTI-BACKFLOW DISCHARGING DEVICE USED FOR A LIQUID BOTTLE FOR PREVENTING OTHER MATERIALS FROM BEING INJECTED INTO THE BOTTLE ILLEGALLY BY FORMING PLURAL ANTI-BACKFLOW TOOLS

摘要

An anti-backflow discharging device used for a liquid bottle is provided to restrain different kinds of materials from being inserted into a bottle by successively opening and shutting anti-backflow tools for opening a discharge passage in pressing or inclining the bottle and closing up the discharge passage in erectly setting the bottle or removing pressure applied to the bottle. A discharging device(1) incapable of being separated without destroying the original shape is combined in the content discharging direction of a bottle(100). Plural anti-backflow tools(30) having one-way discharging units are formed in a step shape in the discharging device. The anti-backflow tools are opened in inclining the bottle toward one side and closed up in erectly setting up the bottle.
