Abstract
The invention relates to a chemiluminescent light element having at least two chambers, filled with an oxalate solution and an activator solution, or variations of known chemiluminescent light materials including dyes. The oxalate solution is placed within a tight-sealed pouch made of thin aluminum foil lined on its interior side by a polymer, for instance a polyolefin, and so forms the first chamber. This latter is enclosed in a bigger tight-sealed pouch made of translucent polymer film forming the second chamber, which also contains the liquid activator. The outer pouch consists of two polymer films sealed together along their periphery and contain a ball able to pierce the inner pouch by manual action from the user.
