Abstract:
1. A bottle for storing and selectively dispensing liquid in a stream, comprising: a container having flexible side walls enclosing an interior reservoir, and having a first open end providing access to said reservoir; a closure selectively removably coupled to said container proximate said open end such that said reservoir is selectively accessible for filling and refilling, said closure having an aperture; a vent port in communication with said reservoir; a gas-permeable, substantially liquid impermeable membrane disposed within said vent port; an elongate tube having an inner end communicating with said reservoir and an outer end located exteriorly of said container and closure, said tube being inserted into said closure aperture and sealed with respect thereto; and a valve-type nozzle coupled to said outer end of said tube in fluid communication with said reservoir, said valve-type nozzle having an open condition to permit the flow of liquid from said reservoir through said valve-type nozzle and a closed condition to prevent the flow of liquid through said valve-type nozzle from said reservoir, said nozzle operable between open and closed conditions independently of flow from said reservoir.
