Powder gun

#1. Field of the Invention

#This invention relates to dispensing containers. More particularly, it relates to the type of dispensing container known as a powder gun for dispensing a powder into a desired area, or region.

#2. Description of the Prior Art

#FIG. 1 is a perspective view of a powder gun in accordance with one embodiment of this invention.

#FIG. 2 is a disassembled view of the powder gun of FIG. 1 showing the filter therewithin.

#FIG. 3 is a plan view of the dispensing member of FIG. 2 with a finely directing spout thereon.

#Referring to the Figures, and particularly FIGS. 1 and 2, the powder gun 11 includes a body 13 for holding the powder to be dispensed, a dispensing member 15 for dispensing the powder, and a filter and lump break up means 17 for maintaining powder in a dispensible form.

#The body 13 is a hollow collapsible body that is normally biased to an extended position but is movable to a compressed position for discharging air and any powder therewithin from the body. As illustrated, the biasing means that is employed in the collapsible body for maintaing it normally biased in the extended position comprises corrugated, or pleated, plastic in the form of a bellows arrangement in which the normal strength of the plastic resists compression and biases it toward its extended position. If desired, a spiral spring may be wound interiorly of the exterior surface of the body 13 for biasing it to an extended position. As illustrated, the hollow collapsible body 13 has a first aperture 19 at its one end, or bottom. The first aperture 19 is large so as to facilitate filling of the body 13 with the powder to be employed, particularly when in the inverted position, or opposite from that illustrated in FIG. 2. Inherently, the aperture 19 will have a bore extending upwardly into the body 13. Thus, the bore is defined by a cylindrical side wall that forms the basis for a threaded portion 21 to be formed. With this structure, the body 13 has no filling opening from which a stopper or the like would be blown as in the prior art, such as my U.S. Pat. No. 2,349,875. The powder may comprise any of the conventional insecticides, fungicides, rodenticides, weedicides, powders for treating plants, or the like. The body 13 includes a threaded portion 21 that serves as a first connection means portion for connecting the hollow collapsible body to the dispensing member 15.

#The dispensing member 15 has a second aperture 23 adapted to mate with the first aperture of the hollow collapsible body. The dispensing member 15 also includes female threaded portion 25 that serves as a second connection means portion for matingly connecting to the first connection means portion for connecting the hollow collapsible body to the dispensing member. As illustrated, the female threaded portion 25 defines the second aperture 23 and allows the powder to be discharged. A discharge port 27, FIG. 5, penetrates through the side wall in the dispensing member 15 below the threaded portion 21 of the body for discharging the powder. The discharge port 27 has a bore that continues longitudinally of a discharge spout 29, FIGS. 1-5.
