Abstract:
1. A device for emitting powder, comprising: a casing, said casing comprising at least one aperture configured to emit powder therethrough; a cylindrical chamber, defined by a straight wall of circular cross-section, disposed in said casing, said chamber having a proximal end and a distal end, said chamber comprising a ring circumferentially coupled to an inner surface of said chamber; a powder capsule disposed in said chamber; a substantially longitudinal prong, comprising a distal end, a proximal end, and a periphery, disposed in said casing; a sharp puncturing point, disposed on the distal end of the prong, wherein the sharp puncturing point makes the initial puncture in the powder capsule; a primary cutting edge disposed on the periphery of the prong, running from the proximal end of the prong to the distal end of the prong, and terminating at the sharp puncturing point; and a substantially planar face disposed on the periphery of the prong opposite of the primary cutting edge, a distal end of the substantially planar face terminating at an edge opposite the sharp puncturing point; and wherein the substantially longitudinal prong creates an opening in said powder capsule by forming a hanging chad in said powder capsule, the hanging chad having a free end formed by the sharp puncturing point and the primary cutting edge. and a hinge coupled to said powder capsule formed by the substantially planar face and the edge.
