Clip driver

A clip driver for binding materials together by using one of a plurality of clips accommodated in said clip driver, each of said clips being made of a single elastic plate-like member and being constituted by a bent portion and a pair of grasping portions continued from said bent portion and having extremities normally elastically contacting with each other so that said grasping portions can grasp the materials therebetween, said clip driver comprising a casing body having an inner portion for accommodating said plurality of clips and having, at its front end, an opening portion forming an insertion inlet for inserting the materials to be bound, a knob member slidably mounted on said casing body for pushing-out said clip, and an elastic member for elastically biasing said knob member in a direction opposite to a direction pushing-out said clip, in which

• said casing body is made of a rectangular plate-like member of synthetic resin composed of:
• a bottom portion having longitudinally extending opposite edge portions;
• a pair of side portions having longitudinally extending edge portions respectively, each edge portion being bendably continuously connected to each opposite edge portion of said bottom portion;
• a pair of upper portions having longitudinally extending edge portions respectively, each edge portion being continuously connected at substantially right angle to each longitudinally extending edge portion of said respective side portions, each of said upper portions having a width in a direction perpendicular to said longitudinally extending edge portion thereof which is substantially half of a width of said clip driver;
• a cap portion continuously bendably connected at its one side to a rear end of said bottom portion;
• notch portions formed in front end surfaces of said side portions respectively so as to form said opening portion;
• clip opening spring portions formed on said side portions respectively, each of said clip opening spring portions having a vertex end portion and a pair of leg portions extending from said vertex end portion toward said notch portion so as to gradually separate from each other;
• knob openings formed in said respective upper portions adjacently to said notch portions for mounting said knob member;
• a plurality of first hook portions integrally formed on one longitudinally extending edge portion of one of the upper portions so as to project from the upper portion,
• a plurality of second hook portions integrally formed on one longitudinally extending edge portion of the other of the upper portions corresponding to the respective first hook portions;
• and
• said side portions and said cap portion being erected up from said bottom portion at continuously bendable connection portions therebetween so as to form pillar-like casing body having a path for accommodating therein said clips, said first and second hook portions engaging together when the casing body is assembled to complete the casing body.
