Abstract
Abstract A fluid container and dispenser including an elastomeric reservoir and a dispensing tube connected thereto and a valve to either allow or inhibit fluid flow into or out of the reservoir. One embodiment includes an elongate tube with a hole in one side and an elastomeric sleeve surrounding a portion of the tube. A sliding valve element is mounted in the tube to close the hole. The valve element is mounted on a second, smaller tube which slides within the first-mentioned tube. The sleeve is filled by sliding the valve element away from the hole and injecting fluid under pressure into the sleeve to expand it. The valve then is slid to its closed position. The combined first-mentioned and second tubes together form a straw to withdraw fluid from a secondary container into which fluid may be dispensed.

Claim 12
Dependent Claim
49 words
The device in claim 10, wherein said second tube has such length that it projects from one end of said straw when said valve means is in its first position to be engaged for applying a shifting force to move it and said valve means to said second position.
Claim 13
Dependent Claim
55 words
The device of claim 3, wherein said operating element has such length that when said valve means is in its first position, said operating element extends outwardly from one end of the tube allowing it to be engaged for applying a shifting force to move said operating element and sealing element to said second position.
Claim 14
Dependent Claim
100 words
A fluid containing device comprising a tube having an orifice therein, an elastomeric reservoir connected to said tube whereby fluid may flow through said orifice between the interior of the tube and said reservoir, valve means movably mounted in said tube for shifting between a first position closing said orifice to prevent fluid flow therebetween and a second position permitting such fluid flow, and an elongate operating element movably mounted in said tube with a portion of said operating element extending outwardly from said tube for manipulation, and said valve means is connected to said operating element for movement therewith.
Claim 15
Dependent Claim
100 words
A fluid containing device comprising a tube having an orifice therein, an elastomeric reservoir connected to said tube whereby fluid may flow through said orifice between the interior of the tube and said reservoir, valve means movably mounted in said tube for shifting between a first position closing said orifice to prevent fluid flow therebetween and a second position permitting such fluid flow, and an elongate operating element movably mounted in said tube with a portion of said operating element extending outwardly from said tube for manipulation, and said valve means is connected to said operating element for movement therewith.
