ABSTRACT:
The instant invention is a light shield formed integral with chemiluminescent devices to effectively block ambient light thereby inhibiting photo degradation of chemical reagents when exposed to external light sources. The light shield displaces conventional foil or the like product packaging designed to protect against light yet permits instant and easy activation of chemiluminescent reagents without interfering with the chemiluminescent reaction. The integral light shields further simplify packaging and extend the product shelf life of the chemiluminescent reagents.
