ABSTRACT:
A hole puncher formed as one piece of plastic molded into base, handle and receptacle portions hinged together by flexible, foldable joints. The one-piece plastic construction can be assembled quickly as a hole puncher by folding the portions into predetermined positions. A feature of the hole puncher is the use of a plastic locking strap connecting the handle and the base, for maintaining the handle folded over the base. Another feature is the use of translucent plastic material, enabling the user to visually check the desired alignment of pins with the paper to be punched, to assure proper location of the punched holes. The design provides an attractive, affordable and easily assembled design without sacrificing strength and durability.
