Abstract
A miniature pocket flashlight includes a battery receptacle and electrical switch unit, a lamp, and a lens module with an integral lens element which are all encased and covered by an outer sheath of flexible material. The lens module are mounted to an end of the battery receptacle and electrical switch unit and has a central passage formed therein behind the lens element which receives, surrounds and protects the lamp which is also mounted and electrically connected to the one end of the unit. The flexible outer sheath of the pocket flashlight is formed by a pair of flexible flaps integrally connected together at one end where they define an aperture for external exposure of an end of the lens element. The outer sheath is stretched over the components and the peripheral edges of the flexible flaps are attached to one another so as to encase and enclose and thereby retain together the lens module, lamp and battery receptacle and electrical switch unit.
