Abstract
Abstract Fail safe releasible locks for capped centrifuge containers to insure closure integrity against specimen loss in whole or in part, the containers with cap being suitable for use in centrifuging and/or boiling liquid specimens and, if desired, for removal of processed specimens without removal of the lock and without opening of the cap.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
175 words
A releasible lock for holding a capped liquid specimen container in a leak-free closed state during centrifuging, boiling and like processing in a specimen testing laboratory, the releasible lock being formed as one piece of synthetic resinous material with memory and comprising (a) first means to restrainingly engage a closed cap to prevent cap movement in a direction away from a liquid specimen container having an opening at one end which is closed by the cap, (b) second means to restrainingly engage the container adjacent said opening and (c) third means integrally interconnecting the first means to the second means in such a way that the memory of the third means retains the aforesaid engagements prohibiting loss of any portion of the liquid specimen through the opening and across the cap during boiling and centrifuging and whereby the releasible lock can be manually force into the leak-free closed state or removed by the user as desired, the first and second means comprising spaced elongated cross members and the third means comprise parallel spaced longitudinal members.
Claim 2
Dependent Claim
175 words
A releasible lock for holding a capped liquid specimen container in a leak-free closed state during centrifuging, boiling and like processing in a specimen testing laboratory, the releasible lock being formed as one piece of synthetic resinous material with memory and comprising (a) first means to restrainingly engage a closed cap to prevent cap movement in a direction away from a liquid specimen container having an opening at one end which is closed by the cap, (b) second means to restrainingly engage the container adjacent said opening and (c) third means integrally interconnecting the first means to the second means in such a way that the memory of the third means retains the aforesaid engagements prohibiting loss of any portion of the liquid specimen through the opening and across the cap during boiling and centrifuging and whereby the releasible lock can be manually force into the leak-free closed state or removed by the user as desired, the first and second means comprising spaced elongated cross members and the third means comprise parallel spaced longitudinal members.
Claim 3
Dependent Claim
128 words
A releasible lock for holding a capped liquid specimen container in a leak-free closed state during centrifuging, boiling and like processing in a specimen testing laboratory, the releasible lock being formed as one piece of synthetic resinous material with memory and comprising spaced elongated cross members respectively engaging the cap and lip means at one end of the container adjacent a container opening and spaced parallel longitudinal members connected to the cross members such that the memory of the longitudinal members causes said engagements to be maintained prohibiting loss of any portion of the liquid specimen through the opening and across the cap during boiling and centrifuging and whereby the releasible lock can be manually forced into the leak-free closed state or removed by the user as desired.
Claim 4
Dependent Claim
128 words
A releasible lock for holding a capped liquid specimen container in a leak-free closed state during centrifuging, boiling and like processing in a specimen testing laboratory, the releasible lock being formed as one piece of synthetic resinous material with memory and comprising spaced elongated cross members respectively engaging the cap and lip means at one end of the container adjacent a container opening and spaced parallel longitudinal members connected to the cross members such that the memory of the longitudinal members causes said engagements to be maintained prohibiting loss of any portion of the liquid specimen through the opening and across the cap during boiling and centrifuging and whereby the releasible lock can be manually forced into the leak-free closed state or removed by the user as desired.
Claim 5
Dependent Claim
23 words
A releasible lock according to claim 2 wherein the cross members and longitudinal members form at least two loops and three cross members.
Claim 6
Dependent Claim
19 words
A releasible lock according to claim 2 further comprising means by which the lock is tethered to the container.
