Abstract:
1. A baton shaped chemiluminescent light stick comprising; a flexible light transmitting cylinder and a rigid cylindrical breakable vial; said flexible light transmitting cylinder containing said rigid breakable cylindrical vial and a first reactive component of a two part chemiluminescent material, said breakable vial containing a second reactive component of a two part chemiluminescent material; said flexible light transmitting cylinder having an inner diameter and the rigid breakable vial having an outer diameter, the outer diameter of the rigid breakable vial being slightly smaller than the inner diameter of the flexible light transmitting cylinder, the lengths of the flexible light transmitting cylinder and the rigid breakable vial being substantially coextensive, said flexible light transmitting cylinder and rigid cylindrical breakable vial having a length over diameter ratio greater than 10 to 1, said flexible light transmitting cylinder formed from an inner layer made from a low density polyolefin chosen from the family of polyolefins that is typically used for cold food storage and an outer layer made from high density polyolefin modified with 40% by weight ethylene vinyl acetate and chosen from the family of polyolefins that is typically used for warm food storage, said inner and outer layer constructed and arranged to withstanding internal gas pressure up to 400 psig at temperatures ranging from 0 degrees Fahrenheit to 130 degrees Fahrenheit; whereby when the light stick is thrown against a hard object the force of the impact is conducted through said flexible light transmitting cylinder and into the rigid breakable vial, rupturing said vial and causing said first and second reactive components to mix and generate a chemiluminescence.
