Abstract: A biodegradable chemiluminescent article is provided. The article includes a chemiluminescent system including an oxalate component containing a solvent mixture of about 50 wt. % of propylene glycol dibenzoate and about 50 wt. % of methyl benzoate. A container is formed from a blend of at least one non-biodegradable polymer and an additive that makes the non-biodegradable polymer biodegradable.

Abstract: A chemiluminescent system includes a substrate comprising a solid chemiluminescent oxalate and a solution comprising an oxygen-providing compound. The chemiluminescent system provides improved light-output characteristics.

Abstract: A sealed, chemiluminescent novelty device includes a housing having side walls and a bottom wall to define a housing and a lid sealable to the housing. The lid has a flexible membrane with a depending plunger. A sealed charge having side walls and a top wall with a flexible membrane, is positioned in the housing. The charge has an activation post aligned with the membrane. A sealed, frangible ampoule is disposed in the charge. A first chemical is disposed in the charge, outside of the ampoule and a second chemical is disposed in the ampoule. Pressure applied to the housing lid urges contact with the charge top wall to urge the top wall to move the activation post into contact with the ampoule to break the ampoule allowing the first and second chemicals to mix.

Abstract: A sealed, chemiluminescent novelty device includes a housing having side walls and a bottom wall formed as a unitary member to define a housing inner region and a lid sealable to the housing. The housing lid has a flexible membrane with a depending plunger thereon. A sealed charge having side walls and a top wall formed as a unitary member with a flexible membrane, is positioned in the sealed housing. The charge top wall has a depending activation post thereon aligned with the housing lid membrane. A sealed, frangible ampoule disposed in the charge. A first chemical is disposed in the charge, outside of the ampoule and a second chemical is disposed in the ampoule. Pressure applied to the housing lid urges the housing lid into contact with the charge top wall to urge the charge top wall inward of the charge to move the activation post into contact with the ampoule to break the ampoule to allow the first and second chemicals to mix to provide a chemiluminescent lighting effect.

Abstract: A stylet for use with an endotracheal tube includes a lighting element and a malleable rod completely enclosed and sealed within an elongated flexible sheath. The elongated flexible sheath has a proximal end and a distal end; the lighting element is positioned at or near the distal end and the malleable rod is positioned from proximate to the lighting element to the proximal end of the elongated flexible sheath. The chemiluminescent lighting element includes an activator and an oxalate and may be fully enclosed in a capsule or the flexible sheath may serve as an outer wall of the lighting element. An absorbent pad, made from cotton or non-woven fiber, is at the distal end of the elongated sheath between the lighting element and a terminal seal of the elongated flexible sheath. The stylet includes one or more tactile elements and a removable protective cap.
