Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 95 words
Injector filling apparatus comprising: A. a nondeformable container for a fluid sample, said container being closed at one end and open at the other end; B. a self-sealing septum positioned for sealing the open end of the container and adaptable to have injector needle means insertable therethrough; C. and piston means in said container having a bore therethrough adaptable to receive the injector needle means therein and whereby downward movement thereof places a fluid sample in the container under hydraulic pressure and charges the injector needle means with at least a portion of the sample.
Claim 2
Dependent Claim 95 words
Injector filling apparatus comprising: A. a nondeformable container for a fluid sample, said container being closed at one end and open at the other end; B. a self-sealing septum positioned for sealing the open end of the container and adaptable to have injector needle means insertable therethrough; C. and piston means in said container having a bore therethrough adaptable to receive the injector needle means therein and whereby downward movement thereof places a fluid sample in the container under hydraulic pressure and charges the injector needle means with at least a portion of the sample.
Claim 3
Dependent Claim 127 words
Injector filling apparatus, comprising: A. a container for a fluid sample, said container being closed at one end and open at the other; B. pierceable seal covering the open end of the container; C. pressurizing means for putting a fluid sample in the container under pressure for charging an injector with at least a portion of the sample, said pressurizing means comprising a container plunger having a bore extending longitudinally therethrough; D. a cap for retaining the seal sealingly on the open end of the container, said cap having an outer end wall with an axial bore therethrough flaring upwardly, the bore through the container plunger being axially arranged so that the bore in the cap is in axial alignment with the bore in said container plunger.
Claim 4
Dependent Claim 127 words
Injector filling apparatus, comprising: A. a container for a fluid sample, said container being closed at one end and open at the other; B. pierceable seal covering the open end of the container; C. pressurizing means for putting a fluid sample in the container under pressure for charging an injector with at least a portion of the sample, said pressurizing means comprising a container plunger having a bore extending longitudinally therethrough; D. a cap for retaining the seal sealingly on the open end of the container, said cap having an outer end wall with an axial bore therethrough flaring upwardly, the bore through the container plunger being axially arranged so that the bore in the cap is in axial alignment with the bore in said container plunger.
Claim 5
Dependent Claim 63 words
The invention defined by claim 2, including a housing having a recess therein for reception of the container, said recess being open at one end, said recess having a tapped portion at the open end, said cap having an externally threaded body threadably disposed in said tapped portion of the recess, there being an enlarged head at the outer end of said body.
Claim 6
Dependent Claim 151 words
Injector filling apparatus comprising: A. an injector needle means; B. a cylindrical container for a fluid sample, said container being closed at one end and open at the other end; C. a pierceable seal for covering the open end of the container; D. pressurizing means for putting a fluid sample in the container under pressure for charging said injector needle means with at least a portion of the sample, said pressurizing means comprising a cylindrical container plunger operably movable longitudinally in said container, said plunger having a bore extending longitudinally therethrough for reception of a filling end of the injector needle means insertable through the seal and received into the bore through the plunger and engageable with a part of said container plunger whereby said plunger may be moved longitudinally toward the closed end of said container to create injector filling pressure on sample fluid in the container below the plunger.
Claim 7
Dependent Claim 151 words
Injector filling apparatus comprising: A. an injector needle means; B. a cylindrical container for a fluid sample, said container being closed at one end and open at the other end; C. a pierceable seal for covering the open end of the container; D. pressurizing means for putting a fluid sample in the container under pressure for charging said injector needle means with at least a portion of the sample, said pressurizing means comprising a cylindrical container plunger operably movable longitudinally in said container, said plunger having a bore extending longitudinally therethrough for reception of a filling end of the injector needle means insertable through the seal and received into the bore through the plunger and engageable with a part of said container plunger whereby said plunger may be moved longitudinally toward the closed end of said container to create injector filling pressure on sample fluid in the container below the plunger.
Claim 8
Dependent Claim 196 words
Injector filling apparatus comprising: A. a cylindrical container for a fluid sample, said container being closed at one end and open at the other end; B. a pierceable seal for covering the open end of the container; C. a container plunger positioned within said container for putting a fluid sample in the container under pressure for charging an injector with at least a portion of the sample, said plunger having an axial bore with its upper end flaring inwardly to receive the injector therein, said plunger further having an external annular groove therein; D. a housing having a recess therein for the container, said recess having an open end with an enlarged tapped portion at said open end; E. a cap having an externally threaded body threadedly received in said tapped portion of the housing recess, said body having a bore extending from the inner end, the seal for the open end of the container being disposed in the bore in said body, and an enlarged head at the outer end of said body, said head having an outer end wall with an outwardly flaring opening therethrough aligned with the axial bore through the container plunger.
Claim 9
Dependent Claim 196 words
Injector filling apparatus comprising: A. a cylindrical container for a fluid sample, said container being closed at one end and open at the other end; B. a pierceable seal for covering the open end of the container; C. a container plunger positioned within said container for putting a fluid sample in the container under pressure for charging an injector with at least a portion of the sample, said plunger having an axial bore with its upper end flaring inwardly to receive the injector therein, said plunger further having an external annular groove therein; D. a housing having a recess therein for the container, said recess having an open end with an enlarged tapped portion at said open end; E. a cap having an externally threaded body threadedly received in said tapped portion of the housing recess, said body having a bore extending from the inner end, the seal for the open end of the container being disposed in the bore in said body, and an enlarged head at the outer end of said body, said head having an outer end wall with an outwardly flaring opening therethrough aligned with the axial bore through the container plunger.
