Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
A light cell comprising a flexible plastic container including a generally dome shaped member, a generally flat base of transparent flexible plastic material sealed to the dome shaped member to form a liquid tight container, a frangible elongated glass pod containing a first chemiluminescence producing substance adapted to produce chemiluminescent light when mixed with a second substance substantially filling the container outside the pod, means including a pair of opposed indentations in the dome shaped member for retaining the pod against displacement from a position in which it may readily be ruptured by flexure of the container and means on the base including an adhesive covering part of the base for attaching the cell to an article to be illuminated, whereby light is directed onto the article through the transparent base.
Claim 2
Dependent Claim
131 words
A light cell comprising a flexible plastic container including a generally dome shaped member, a generally flat base of transparent flexible plastic material sealed to the dome shaped member to form a liquid tight container, a frangible elongated glass pod containing a first chemiluminescence producing substance adapted to produce chemiluminescent light when mixed with a second substance substantially filling the container outside the pod, means including a pair of opposed indentations in the dome shaped member for retaining the pod against displacement from a position in which it may readily be ruptured by flexure of the container and means on the base including an adhesive covering part of the base for attaching the cell to an article to be illuminated, whereby light is directed onto the article through the transparent base.
Claim 3
Dependent Claim
30 words
A light cell according to claim 1 further comprising an opaque coating on the exterior of the dome shaped member for containing the light against passage except through the base.
Claim 4
Dependent Claim
33 words
A light cell according to claim 1 further characterized in that the exterior of the dome shaped member is covered by an opaque sprippable coating for containing the light output of the cell.
Claim 5
Dependent Claim
24 words
A light cell according to claim 3 further characterized in that the coating is reflective for directing the light output through the transparent base.
Claim 6
Dependent Claim
26 words
A light cell according to claim 1 further comprising a strip into which the cell is detachably retained as one of a plurality of like cells.
