Abstract A powder gun for dispensing a powder such as an insecticide or the like characterized by a hollow collapsible body for containing the powder, a dispensing member having a discharge port and spout for directing the discharged powder into the desired area and connected with the hollow collapsible body, and a filter and lump break up means disposed within the dispensing member immediately adjacent the discharge port for breaking up lumps and for filtering the powder and preventing entry of particles large enough to plug the discharge port and spout. The hollow collapsible body is normally biased to an extended position and movable to a compressed position for discharging air and any powder therewithin through the dispensing member. Also disclosed are preferred structural embodiments including a rotatable disc having multiple sections of stalks protruding substantially perpendicularly thereto for breaking up the lumps and for filtering the powder dispensed through the discharge spout, as well as preferred materials of construction.
A powder gun adapted for dispensing a powder regardless of lumps that may tend to form therein comprising: a. a hollow collapsible body that is normally biased to an extended position and movable to a compressed position for discharging air and any powder therewithin from said body through an aperture and a dispensing member; said hollow collapsible body including: i. a first aperture at one end; and ii. a first connection means portion for connecting said hollow collapsible body to a dispensing member; b. a dispensing member having: i. a second aperture adapted to mate with said first aperture of said hollow collapsible body; ii. a second connection means portion for matingly connecting to said first connection means portion for connecting said hollow collapsible body to said dispensing member, said second connection means portion being disposed adjacent said second aperture; iii. a discharge port disposed in said dispensing member and penetrating through a wall thereof for discharging powder therethrough; and iv. a discharge spout connected with said discharge port for directing said discharged powder into a desired area; and c. a filter and lump break-up means disposed in said dispensing member immediately adjacent said discharge port for breaking up lumps and for filtering said powder and preventing entry of particles large enough to plug said discharge spout; said filter and lump break-up means comprising a rotatable disc rotatably mounted in said discharge member and having at least two sections of upstanding stalks disposed at a predetermined angle with respect to said disc; said stalks being of respective predetermined diameters and disposed at respective predetermined distances apart in the respective sections to achieve the desired filtering action and being sized and shaped to achieve the desired break up of any lumps that tend to form.
