Abstract

An ultra-violet ray water sterilizer comprising a container having two chambers connected together only adjacent the bottom internal surfaces of the chambers, one chamber containing a germicidal ultra-violet ray lamp extending up the chamber from the bottom surface thereof, the said one chamber having an outlet adjacent the top of the ultra-violet lamp, the second chamber having a water inlet. Thus, the water may be poured into the said second chamber and when this is to be dispensed upon tilting the units so that water emerges from the outlet at the top of the first chamber, all the water passes the ultra-violet ray lamp and becomes sterilized.

Claims

1. A portable ultra-violet ray water sterilizer comprising

a container having first and second chambers with a water passage therebetween only adjacent the bottom internal surfaces of said chambers, said container being sized so that it is manually portable,

a water outlet adjacent the top of said first chamber, and a water inlet for said second chamber, wherein said water outlet is a pouring spout and

a germicidal ultra-violet ray lamp fixed in said first chamber, said lamp extending up from the bottom internal surface of said first chamber, said first chamber and said lamp being sized to provide a relatively close fit therebetween so that all water is sterilized at it flows through said first chamber between said passage and whereby tipping said container causes substantially all of said water in said second chamber to flow through said first chamber between said lamp and the surface of said first chamber, sterilizing said water as it flows through said first chamber and out said container.

2. A portable sterilizer as claimed in claim 1, said sterilizer comprising

a quartz thimble positioned in said first chamber, said lamp being surrounded by said thimble.

3. A portable sterilizer as claimed in claim 1, said sterilizer comprising

a teflon tube positioned in said first chamber, said lamp being surrounded by said tube.

4. A portable sterilizer as claimed in claim 1, said sterilizer comprising

a drinking glass mounted to said container, said drinking glass being positioned within said first chamber with its open end extending over said lamp.
