Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
65 words
A chemiluminescent device according to claim 1 wherein, additionally, a second breakable glass inner container having a constricted neck to facilitate breakage thereof and having a component of a multi-component chemiluminescent system sealed within it is rigidly held in place within said outer container by means of a portion of said outer container being shrunk inwardly around a portion of said second breakable inner container.
Claim 2
Dependent Claim
30 words
A chemiluminescent device according to claim 2 wherein said second breakable inner container has a quenching material selected from the group consisting of primary and secondary amines sealed within it.
Claim 3
Dependent Claim
18 words
A chemiluminescent device according to claim 2 wherein said second inner container has hydrogen peroxide sealed within it.
Claim 4
Dependent Claim
23 words
A chemiluminescent device according to claim 2 wherein said second inner container has a solution of oxalate ester and fluorescer sealed within it.
Claim 5
Dependent Claim
99 words
In the method of fabricating a chemiluminescent device which comprises sealing at least one closed breakable container which contains a component of a chemiluminescent system within an outer container which contains another component of the chemiluminescent system, the improvements which reside in fabriCating the closed breakable container with a constricted neck to facilitate breakage thereof, fabricating the outer container from radiation cross-linked polyolefin, shrinking a portion of the outer container around a portion of the closed breakable container to hold the closed breakable container rigidly in place and permanently heat sealing the outer container closed at both ends thereof.
