Abstract
A chemiluminescent illuminated device employing a light-filtering injection molded polygonal shaped container that is scalloped to form an augmented illumination surface. The shaped housing includes a round shaped or form following chemical holding section. The lighting effects generated by the chemiluminescent chemical is enhanced by the polygonal shape and the inherent optical properties.
Claims12
A method of manufacturing a polygonal chemiluminescent device comprising the steps of:
- injection molding a light-filtering container having an inner cavity having a center and sized to support chemiluminescent reagents and an outer shape, said outer shape having a generally rectangular cross section and a plurality of side walls at a distance from said center which intersect to form side wall corners;
- forming a plurality of scalloped surfaces within each of said side walls, each of said scalloped surfaces including an inwardly directed curved surface that merges with an adjacent scalloped surface to form said side wall corners and intermediate intersecting corners within each of said side walls, wherein the distance from the center of said inner cavity to the tips of said side wall corners is greater than the distance from said center of said inner cavity to the tips of said intermediate intersecting corners;
- inserting reagents into and sealing said inner cavity;
- whereby activation of said chemiluminescent reagents produces chemiluminescent light providing enhanced lighting at said side wall corners and said intermediate intersecting corners from a given amount of said reagents.

A chemiluminescent device comprising:
- chemiluminescent reagents, a light-filtering thermoformed container having an inner cavity having a center and sized to support said chemiluminescent reagents and an outer shape having a generally rectangular cross section and having a plurality of side walls at a distance from said center which intersect to form side wall corners, each of said side walls including a plurality of inwardly directed curved surfaces which merge with adjacent curved surfaces to form said side wall corners and intermediate intersecting corners within each of said side walls, wherein the distance from the center of said inner cavity to the tips of said side wall corners is greater than the distance from said center of said inner cavity to the tips of said intermediate intersecting corners;
- whereby the activation of said chemiluminescent reagents produces chemiluminescent light which when transmitted throughout said outer shape provides enhanced lighting at said side wall corners and said intermediate intersecting corners from a given amount of said reagents.
