Abstract
Abstract A fluid dispensing device comprising (a) a housing having a closed end, and opposite open end and fluid release opening extending through the wall of the housing; (b) an inner member adapted to contain a fluid and having one open end, an opposite closed end, a length substantially coextensive with the length of said housing and an outside cross-sectional dimension smaller than the inside cross-sectional dimension of the housing; the open end of the inner member being insertable in the open end of the housing thereby providing an annular space between the wall of the housing and the inner member; (c) the open end of the inner member being engageable with the closed end of the housing so as to form a first releasable seal to contain the fluid in the inner member; and (d) threads provided on the inner member adjacent its closed end and engageable with threads provided on the housing adjacent its open end so as to form a second releasable seal.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
199 words
A fluid dispenser comprising: a. a housing having a closed end, an opposite open end and fluid release opening means extending through the wall of said housing; b. an inner member adapted to store a fluid and having one open end, an opposite closed end, a length substantially coextensive with the length of said housing and an outside cross-sectional dimension smaller than the inside cross-sectional dimension of said housing; said open end of said inner member being insertable in said open end of said housing thereby providing an annular space between the wall of said housing and said inner member; c. said open end of said inner member being engageable with said closed end of said housing so as to form a first releasable sealing means to contain said fluid in said inner member; and d. means provided on said inner member adjacent its closed end and engageable with means provided on said housing adjacent its open end so as to form a second releasable sealing means, the portion of said inner member extending from said open end of said inner member to said means adjacent the closed end of said inner member being adapted to store said fluid.
Claim 2
Dependent Claim
199 words
A fluid dispenser comprising: a. a housing having a closed end, an opposite open end and fluid release opening means extending through the wall of said housing; b. an inner member adapted to store a fluid and having one open end, an opposite closed end, a length substantially coextensive with the length of said housing and an outside cross-sectional dimension smaller than the inside cross-sectional dimension of said housing; said open end of said inner member being insertable in said open end of said housing thereby providing an annular space between the wall of said housing and said inner member; c. said open end of said inner member being engageable with said closed end of said housing so as to form a first releasable sealing means to contain said fluid in said inner member; and d. means provided on said inner member adjacent its closed end and engageable with means provided on said housing adjacent its open end so as to form a second releasable sealing means, the portion of said inner member extending from said open end of said inner member to said means adjacent the closed end of said inner member being adapted to store said fluid.
