Abstract
Abstract A multi-purpose miniature pocket flashlight having a flexible case that contains a cartridge and lamp assembly. The cartridge is capable of holding a pair of batteries in association with a spring switch arm operable by squeezing the flexible casing to complete the electrical circuit and illuminate the lamp. The lamp and batteries are removable and replaceable by the provision of a removable cap means at either of the ends of said casing. The flashlight further includes a mounting magnet arranged within the case adjacent the cartridge whereby the flashlight may be magnetically secured against a metallic wall, for example. The invention also includes a bottom cap for said flexible casing that is designed to provide a watch chamber below said cartridge. The cap has a centrally open bottom wall that opens to said chamber. A watch means, having a casing shaped to nest within said watch chamber, is arranged therein so that its time display is positioned at said bottom wall opening to be visible from the bottom of the flashlight. The watch means is fully removable from said flexible casing.
