CHEMILUMINESCENT LIGHT APPARATUS AND METHOD OF MANUFACTURE

摘要

A chemiluminescent light apparatus is provided which includes a two-piece casing (10) that encloses a chemiluminescent composition (12). The casing includes a light-transmissive body (14) defining an interior cavity and including an end wall presenting an opening that communicates with the cavity, and a cap (16) received in the opening. The opening is stepped to define a shelf (28) that is generally parallel to and spaced from the end wall of the body, and the cap (16) includes a stepped region presenting a shoulder (36) that is sealed against the shelf of the opening to close off the interior cavity of the body. A first fluid component (18) of the chemiluminescent composition is enclosed in the interior cavity of the body, as is a hollow frangible ampule (22) within which a second component (20) of the composition (12) is encapsulated. When the ampule (22) is fractured, the first and second fluid components (18, 20) mix together and luminesce. A method of manufacturing a chemiluminescent light apparatus is also provided, wherein a light-transmissive body is positioned on a rotatable turntable (40) that is indexed from station to station to permit the various components of the apparatus to be assembled. At one of the stations, a cap is secured to the body by ultrasonic welding. .
