Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
49 words
A method for opening a light waveguide splice closure having a container and an end cap having hollow grounding lugs, comprising: immobilizing the container, affixing lifting handles to the hollow lugs in the end cap, and pulling on the lifting handles to remove the end cap from the container.
Claim 2
Independent Claim
49 words
A method for opening a light waveguide splice closure having a container and an end cap having hollow grounding lugs, comprising: immobilizing the container, affixing lifting handles to the hollow lugs in the end cap, and pulling on the lifting handles to remove the end cap from the container.
Claim 3
Dependent Claim
86 words
A light waveguide splice closure, comprising: a container having an end cap through which light waveguides may be inserted, said container holding splicing means for placing light waveguides into optical communication with each other and a vessel located between the end cap and the splicing means for holding encapsulant, said vessel having (1) an open top having a flared resilient brim forming a seal with the interior of the container and (2) a bottom having means for light waveguides to pass therethrough to the splicing means.
