Abstract
Abstract A chemiluminescent device is disclosed wherein a first polymeric sheet having a shaped cavity therein is sealed around its periphery to a second polymeric sheet and the cavity contains (1) an absorbent article produced from a polyolefin, or a polyester or glass fibers and being of substantially the same shape as the cavity and (2) a sealed receptacle containing a first liquid component of a chemiluminescent light composition and wherein there is also present, outside said sealed receptacle, a second liquid component of a chemiluminescent light composition, said absorbent article conforming to seven critical chemical limitations.

Claim 1
Independent Claim
263 words
A chemiluminescent device comprising, in sequential relationship, A. a first polymeric sheet of 0.01-0.5 inch thickness being translucent or transparent and having a shaped cavity therein, said cavity capable of receiving a liquid-absorbent article, B. a non-woven, liquid-absorbent article made from a polyolefin, a polyester or glass fibers, said article being of substantially the same shape as said cavity, c. a first sealed, breakable receptacle containing a quantity of a first liquid component of a chemiluminescent light composition capable of providing chemiluminescent light when mixed with a second component, D. a quantity of a second liquid component of a chemiluminescent light composition outside said first sealed receptacle, and E. a second polymeric sheet of 0.2-0.6 inch thickness, sealed around its perifery to the periphery of said first polymeric sheet, the sum of the quantities of components C and D being such that when absorbed on component B, component B is substantially completely saturated thereby, said liquid-absorbent article: (i) being capable of absorbing and retaining substantially the complete volume of said chemiluminescent light composition to thereby result in substantially complete saturation of the article; (ii) being capable of allowing mixing of said first and second components of said composition after being absorbed thereby; (iii) having a uniform density across its widest surface; (iv) being inert with regard to said composition and said first and second components; (v) being substantially non-deformable in use in said device; (vi) being capable of substantially instantaneous absorption of said first and second components, alone or when admixed, and (vii) being opaque when substantially completely saturated with said chemiluminescent composition.
