Abstract:
1. A pencil housing and sharpener comprising: a housing having an inner cavity for receiving at least a portion of a pencil therein, the pencil comprising a center portion and an outer portion generally coaxial with the center portion; a sharpener longitudinally slidable within the inner cavity for sharpening the center and outer portions of the pencil, the sharpener being non-rotatable relative to the housing; and a spring for providing a linear force to the sharpener to move the sharpener between open and closed ends of the housing, the spring being disposed between the sharpener and the closed end of the housing; a removable closure having a recess for receiving an end of the pencil such that the pencil is non-rotatable relative to the closure, the closure mating with the housing to encase the pencil, the closure being rotatable relative to the housing to cause rotation of the pencil relative to the sharpener, said sharpener advancing from the closed end to the open end as the pencil decreases in length, thus increasing the capacity of a shavings reservoir in the inner cavity between the sharpener and the closed end.
