ABSTRACT:
A protective closure for an implement such as a pencil or pen. The closure comprises a retractable sheath intended for an attached relation to the implement body portion. The sheath having fold means is shortened or contracted longitudinally to achieve an exposing position when opposing sections of the sheath are urged together, achieving an intermediate, cross-sectionally continuous fold thereby. The fold means is further adapted to self-retain.
