Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
77 words
A sample container for use in a centrifuge rotor having a pair of knife-like pivot edges therein comprising: a body member having a sample-receiving volume therein; a planar pivot surface on the body, the surface being adapted to operably engage along one diametrical dimension thereof each of the pivot edges for supported pivotal movement thereon from a first to a second position; and guide means on the container for guiding the same during the pivotal motion thereof.
Claim 2
Dependent Claim
77 words
A sample container for use in a centrifuge rotor having a pair of knife-like pivot edges therein comprising: a body member having a sample-receiving volume therein; a planar pivot surface on the body, the surface being adapted to operably engage along one diametrical dimension thereof each of the pivot edges for supported pivotal movement thereon from a first to a second position; and guide means on the container for guiding the same during the pivotal motion thereof.
Claim 3
Dependent Claim
37 words
The sample container of claim 1 wherein the container further comprises a cap removably connectable to the body member to afford access to the volume therein, the pivot surface being defined on the undersurface of the cap.
Claim 4
Dependent Claim
36 words
The sample container of claim 2 wherein the body has a central axis extending longitudinally therethrough and wherein the pivot edges engage the surface along an interrupted line contact that intersects the axis of the container.
Claim 5
Dependent Claim
45 words
The sample container of claim 3 wherein the rotor has a guide slot thereon and wherein the guide means comprises a guide pin on the cap adapted to cooperate with the guide slot on the rotor to guide the container during the pivotal movement thereof.
Claim 6
Dependent Claim
37 words
The sample container of claim 4 wherein the rotor has a stop surface thereon and wherein the pin on the cap is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 7
Dependent Claim
35 words
The sample container of claim 3 wherein the rotor has a stop surface thereon and wherein the guide means is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 8
Dependent Claim
35 words
The sample container of claim 3 wherein the rotor has a stress confining enclosing therearound and the body has a spherical surface at one end thereof abuttable in a force transmissive relationship with the enclosure.
Claim 9
Dependent Claim
45 words
The sample container of claim 2 wherein the rotor has a guide slot thereon and wherein the guide means comprises a guide pin on the cap adapted to cooperate with the guide slot on the rotor to guide the container during the pivotal movement thereof.
Claim 10
Dependent Claim
37 words
The sample container of claim 8 wherein the rotor has a stop surface thereon and wherein the pin on the cap is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 11
Dependent Claim
35 words
The sample container of claim 2 wherein the rotor has a stop surface thereon and wherein the guide means is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 12
Dependent Claim
35 words
The sample container of claim 2 wherein the rotor has a stress confining enclosing therearound and the body has a spherical surface at one end thereof abuttable in a force transmissive relationship with the enclosure.
Claim 13
Dependent Claim
36 words
The sample container of claim 1 wherein the body has a central axis extending longitudinally therethrough and wherein the pivot edges engage the surface along an interrupted line contact that intersects the axis of the container.
Claim 14
Dependent Claim
45 words
The sample container of claim 12 wherein the rotor has a guide slot thereon and wherein the guide means comprises a guide pin on the body adapated to cooperate with the guide slot on the rotor to guide the container during the pivotal movement thereof.
Claim 15
Dependent Claim
37 words
The sample container of claim 13 wherein the rotor has a stop surface thereon and wherein the pin on the body is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 16
Dependent Claim
35 words
The sample container of claim 12 wherein the rotor has a stop surface thereon and wherein the guide means is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 17
Dependent Claim
35 words
The sample container of claim 12 wherein the rotor has a stress confining enclosing therearound and the body has a spherical surface at one end thereof abuttable in a force transmissive relationship with the enclosure.
Claim 18
Dependent Claim
45 words
The sample container of claim 1 wherein the rotor has a guide slot thereon and wherein the guide means comprises a guide pin on the body adapated to cooperate with the guide slot on the rotor to guide the container during the pivotal movement thereof.
Claim 19
Dependent Claim
37 words
The sample container of claim 17 wherein the rotor has a stop surface thereon and wherein the pin on the body is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 20
Dependent Claim
35 words
The sample container of claim 1 wherein the rotor has a stop surface thereon and wherein the guide means is adapted to engage the stop surface to prohibit pivotal movement thereof past the second position.
Claim 21
Dependent Claim
35 words
The sample container of claim 1 wherein the rotor has a stress confining enclosing therearound and the body has a spherical surface at one end thereof abuttable in a force transmissive relationship with the enclosure.
