(under subclass 157) Subject matter wherein the casing encloses a battery and also holds an electric light source or support therefor or wherein there is a support to hold a battery and an electric light source or support therefor, and wherein (1) the arrangement of the battery, light source and/or light source support is designed not to be reused, or (2) the casing or support is formed in part of a material which is deformable.
(1) Note. The term "deformable" includes plastic, metal in the form of foil and cellulose material such as paper. Here, the casing or support may be extruded, cast or stamped or may be a wrapping, but the material of the casing or support is flexible.
(2) Note. If, as recited, the battery is integral with a bulb or a bulb socket or light modifier and the unit is a "throw-away," the claim is classifiable in the subclass. If, as recited, only the battery pack unit, as opposed to a
battery or individual batteries which can be replaced, is replaceable and separable from the light bulb or bulb socket and the battery pack unit supports the lamp bulb or lamp bulb socket, the claim is classifiable in subclasses 194+.
