Abstract: A package for an illuminating writing implement is provided which protects the writing implement, yet gives a consumer limited and controlled access to the operating mechanism used to activate the illumination of the writing implement while it remains packaged. The present package is a blister-type package which envelops the writing implement and protects it from abrasive and impact damage as well as, theft. An upper end of the writing implement includes a power switch which is linearly displaceable between an off position, a momentary-on position, and a locked-on position. An opening within the package allows the power switch to extend outside the package so that a consumer may operate the power switch without removing the writing implement from the package. The opening is sized and shaped to restrict linear displacement of the power switch between the off position and the momentary-on position.

Abstract: A writing implement having a built-in illumination system includes a pen-top, a translucent pen-body, and a translucent pen-tip. A battery, an electrical switch and a lamp are housed within the pen-top so that light may be selectively generated by the lamp and directed generally along a central axis within the pen-body portion towards the pen-tip. A marking element is located within said pen-body, partially extending from said pen-tip. A lens is positioned between said lamp and said marking element so that light from the lamp is diverted away from the central axis to the pen-body which guides the received light to the pen-tip. Printed information located on the pen-body is illuminated, as well as a region located immediately adjacent to the pen-tip.
