Abstract
The present invention teaches a chemiluminescent device along with a process for its production. The invention specifically relates to a chemiluminescent article of manufacture (FIG. 1), which includes a containment device (12) having polymeric outer containment (18, 20), and chemical system of oxalate solution inside frangible vial (14), and activator inside frangible vial (16), both the containment device and chemical system may be selected to be particularly susceptible to environmental degradation subsequent to their use. In a preferred embodiment, the chemiluminescent device is designed for an enhanced shelf life prior to use while remaining capable of losing its physical form and re-entering the environment after use.
Claims18
A chemiluminescent light producing device comprising:
- a polymeric outer containment device;
- at least one pair of frangible ampoules positioned within said containment device, each said pair of ampoules providing a chemiluminescent light producing system including an ampoule containing an oxalate component and an ampoule containing a peroxide component;
- wherein said oxalate component and said peroxide component are constructed and arranged to produce visible light when intermixed within said polymeric outer containment device.
A chemiluminescent light producing device comprising:
- an outer containment device formed from a polyvinyl polymer composition;
- at least one pair of frangible ampoules positioned within said containment device, each said pair of ampoules providing a chemiluminescent light producing system including an ampoule containing an oxalate component and including a solvent system containing from 0%-100% acetyl tributyl citrate, from 0%-100% propylene glycol dibenzoate, and glyceryl tribenzoate and/or propylene glycol tribenzoate in an amount effective to increase the solubility of oxalates within said solvent system;
- and an ampoule containing an activator component including triethyl citrate, t-butanol, hydrogen peroxide and sodium salicylate;
- wherein upon fracturing of said ampoules, visible light is produced when said oxalate component and activator component are intermixed within said polymeric outer containment device.
A chemiluminescent light producing device comprising a biodegradable polymeric composition, said biodegradable polymeric composition forming an outer containment device enclosing at least one inner frangible vial, said outer containment device and said vial containing a chemical system, said outer containment device and said vial each containing one of an oxalate component and a peroxide component of said chemical system, separately, said oxalate component and said peroxide component producing visible light when intermixed in said polymeric outer containment device;
- and
- said biodegradable polymeric composition comprises at least one polymeric material selected from the group consisting of polyglycolic acid, polyactic acid, polycaprolactone, polyhydroxybutyrate, polyhydroxyvalerate, polyvinyl alcohol, polyvinyl acetate, a water-soluble blend of polyvinyl alcohol and polyvinyl acetate (PVA), and polyetherketone;
- wherein the exterior surface of said biodegradable polymeric containment device is modified by application of an oxidant or irradiation in an amount effective to crosslink said polymer, thereby improving wet handling characteristics.
