  "description_excerpt": "1. Field of the Invention\n\nThe present invention relates to hand held guns, applicators and syringes for craft materials, and more particularly, the invention relates to novel hand held craft applicator apparatus employing a simple yet unique coupling for pivoting a plunger rod between an unaligned position for fun and quick filling and refilling of a modeling compound and an aligned position for easy extruding of the modeling compound. The portable craft applicator apparatuses also employ simple yet unique storage cavities at a plunger handle and/or a housing handle for storing a plunger rod pivoted to a folded position and resting intermediate the plunger handle and housing handle for quick and easy transport of the folded apparatuses.\n\n2. Background of the Invention\n\nThere are several known hand held syringes for dispensing fluids as well as some known hand held extrusion devices for extruding other flowable materials. Some of the known syringes include two handles cooperating to actuate a plunger or piston and other extruding devices employ a trigger or single handle to compress a fluid cartridge or push flowable materials through a tube. None of the known devices however, employ a simple yet unique coupling for pivoting a plunger rod between two positions, first aligning the plunger rod with a housing receptacle for traversing the rod within the receptacle and extruding a modeling compound, and second pivoting the plunger rod to an unaligned position with the receptacle for fun and quick refilling.",
