Abstract

A portable illumination device consisting of a substantially flat battery having a top and bottom surface and having a bulb receiving means provided substantially in the center of the battery in which the positive and negative terminals of the battery are disposed. The bulb receiving means comprises a socket which is disposed co-axially within, and may be a metal socket, or integrally formed in, the carbon electrode of the battery. The socket forms the positive terminal of the battery, while a zinc can surrounding the battery forms the negative electrode.

Claims

1. A portable illumination device, comprising:

a flat, dry cell battery having positive and negative electrodes, said positive electrode comprising an electrically conductive rod disposed in the center of said battery and including a recess for receiving a lamp, and said negative electrode comprising an electrically conductive metallic casing electrically insulated from said rod;

an electrically conductive, threaded lamp socket, disposed in said recess in said rod, and electrically insulated from said negative electrode, for receiving a lamp;

a lamp, disposed in said lamp socket;

a decorative ornament, having a centrally disposed aperture provided therein;

an annular locking member, disposed in said aperture in said decorative ornament, for disposal over and engagement with said lamp, for securing said decorative ornament thereon so that said lamp extends through said aperture in said ornament; and

adhesive means, disposed on the bottom surface of said battery, for securing said battery, lamp and decorative ornament on a gift package.

2. A portable illumination device, comprising:

a flat, dry cell battery having positive and negative electrodes, said positive electrode comprising a rectangular-shaped electrically conductive rod disposed in the center of said battery having a truncated oval-shaped recess, and said negative electrode comprising an electrically conductive metallic casing electrically insulated from said rod;

a lamp, having a truncated oval-shaped base of dimensions smaller than said recess, slidably disposed in said recess in said rod;

a decorative ornament, having a centrally disposed aperture, for disposal over said lamp;

an annular locking member, disposed in said aperture in said decorative ornament, for disposal over and engagement with said lamp, for securing said decorative ornament to said lamp; and

adhesive means, disposed on one surface of said battery, for securing said battery, lamp and decorative ornament to a gift package.

3. The portable illumination device as recited in claim 1, wherein said lamp further comprises a rectangular-shaped collar, disposed perpendicular to said lamp base, for engaging the top surface of said battery when said lamp is slidably disposed in said recess.
