Abstract
Abstract A fluid dispensing container having a container body provided with opposed ends one of which has a dispensing unit projecting therefrom for dispensing fluid from the container. An annular collar is carried by the container body and projects beyond the dispensing end to tend to protect the dispensing unit and permit a plurality of like dispensing containers to be disposed in vertically stacked relation with the rear end of each container body being adapted to be supported in telescoped relation in the collar of a dispensing container disposed below the same in such stack. The dispensing container includes a needle-like member for permitting an external charging source to charge the dispensing container with a propellant for providing the dispensing force on the fluid in the container body thereof, the charging source including an outlet member that is coupled to the needle-like member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
211 words
A fluid dispensing container comprising; a container body having a chamber therein for storing said fluid, a dispensing unit for dispensing said fluid from said chamber to the exterior of said container body; said dispensing unit having a plate and a bore in said plate; and means for permitting an external charging source to charge said chamber with a propellant to provide a dispensing force for said fluid in said chamber, said means comprising a retainer fixed in said bore, said retainer having a cylindrical inside surface defining a longitudinal opening therethrough, a needle-like tubular member extending through said longitudinal opening and being carried by said retainer, said needle-like tubular member having an outside surface sealed against said cylindrical inside surface, said needle-like tubular member having an outer projecting part arranged outwardly of said retainer and having a passage therein provided with an inlet externally located relative to said container body and said retainer with said outer projecting part of the needle-like tubular member and said inlet being in a protected position within said bore, and said needle-like tubular member having an outlet located in said chamber, said container body having an encasing one-way check valve disposed within said chamber and about said outlet to separate said outlet from said chamber.
Claim 2
Dependent Claim
211 words
A fluid dispensing container comprising; a container body having a chamber therein for storing said fluid, a dispensing unit for dispensing said fluid from said chamber to the exterior of said container body; said dispensing unit having a plate and a bore in said plate; and means for permitting an external charging source to charge said chamber with a propellant to provide a dispensing force for said fluid in said chamber, said means comprising a retainer fixed in said bore, said retainer having a cylindrical inside surface defining a longitudinal opening therethrough, a needle-like tubular member extending through said longitudinal opening and being carried by said retainer, said needle-like tubular member having an outside surface sealed against said cylindrical inside surface, said needle-like tubular member having an outer projecting part arranged outwardly of said retainer and having a passage therein provided with an inlet externally located relative to said container body and said retainer with said outer projecting part of the needle-like tubular member and said inlet being in a protected position within said bore, and said needle-like tubular member having an outlet located in said chamber, said container body having an encasing one-way check valve disposed within said chamber and about said outlet to separate said outlet from said chamber.
Claim 3
Dependent Claim
24 words
A fluid dispensing container as set forth in claim 1 wherein said needle-like tubular member has said outlet provided therein at its terminal end.
Claim 4
Dependent Claim
42 words
A fluid dispensing container as set forth in claim 1 wherein said needle-like tubular member has a closed end at said external location thereof and said inlet being disposed in the side of said needle-like tubular member adjacent said closed end thereof.
Claim 5
Dependent Claim
29 words
A fluid dispensing container as set forth in claim 3 wherein said closed end of said needle-like member is rounded to facilitate needle-like insertion thereof for propellant charging purposes.
Claim 6
Dependent Claim
233 words
In combination: a fluid dispensing container comprising; a container body having a chamber therein for storing said fluid, a dispensing unit for dispensing said fluid from said chamber to the exterior of said container body; said dispensing unit having a plate and a bore in said plate; means for permitting an external charging source to charge said chamber with a propellant to provide a dispensing force for said fluid in said chamber, said means comprising a retainer fixed in said bore, said retainer having a cylindrical inside surface defining a longitudinal opening therethrough, a needle-like tubular member extending through said longitudinal opening and being carried by said retainer, said needle-like tubular member having an outside surface sealed against said cylindrical inside surface, said needle-like tubular member having an outer projecting part arranged outwardly of said retainer and having a passage therein provided with an inlet externally located relative to said container body and said retainer with said outer projecting part of the needle-like tubular member and said inlet being in a protected position within said bore, and said needle-like tubular member having an outlet located in said chamber, said container body having an encasing one-way check valve disposed within said chamber and about said outlet to separate said outlet from said chamber; and an external charging source having an outlet member coupled to said needle-like member for charging said chamber with said propellant.
Claim 7
Dependent Claim
233 words
In combination: a fluid dispensing container comprising; a container body having a chamber therein for storing said fluid, a dispensing unit for dispensing said fluid from said chamber to the exterior of said container body; said dispensing unit having a plate and a bore in said plate; means for permitting an external charging source to charge said chamber with a propellant to provide a dispensing force for said fluid in said chamber, said means comprising a retainer fixed in said bore, said retainer having a cylindrical inside surface defining a longitudinal opening therethrough, a needle-like tubular member extending through said longitudinal opening and being carried by said retainer, said needle-like tubular member having an outside surface sealed against said cylindrical inside surface, said needle-like tubular member having an outer projecting part arranged outwardly of said retainer and having a passage therein provided with an inlet externally located relative to said container body and said retainer with said outer projecting part of the needle-like tubular member and said inlet being in a protected position within said bore, and said needle-like tubular member having an outlet located in said chamber, said container body having an encasing one-way check valve disposed within said chamber and about said outlet to separate said outlet from said chamber; and an external charging source having an outlet member coupled to said needle-like member for charging said chamber with said propellant.
Claim 8
Dependent Claim
42 words
