Abstract

A diffuser for granular herbicide dispensers which is formed of two sections constructed from plastic. Each section consists of a generally vertical wall having flanges along its side edges and a plurality of integrally formed protrusions. When the two sections are placed together the flanges overlap and the protrusions abut. The flanges which form sidewalls are generally downwardly divergent so that, as material is dispensed through the diffuser it strikes the protrusions and is spread laterally over a relatively wide area.

Claims

1. A diffuser for granular materials comprising:

a generally vertically disposed structure having front and rear walls;

there being flanges along the side edges of each wall projecting toward the other wall and overlapping the flanges on the other wall;

the flanges forming sidewalls;

a plurality of protrusions integrally formed on each of the front and rear walls with each protrusion on each wall being spaced from at least one other protrusion on the same wall in both the horizontal and vertical directions; and

each protrusion projecting toward the opposite wall approximately one-half the distance which the flanges project;

the protrusions on each wall being positioned to have their inner ends abut the inner ends of corresponding protrusions on the opposite wall; and

means maintaining the front and rear walls in a position with their flanges overlapping and their protrusions abutting;

whereby material dispensed between the walls will strike the protrusions and be diffused over a relatively wide area.

2. The diffuser set forth in claim 1 wherein the front and rear walls are positioned generally parallel to each other, the upper portion of the sidewalls extend generally parallel to each other and are spaced a distance substantially equal to the spacing between the front and rear walls to form a generally rectangular upper throat portion, the lower portion of the sidewalls are downwardly divergent to form a generally triangular lower portion, and the protrusions on the front and rear walls are spaced between the divergent portions of the sidewalls.

3. The diffuser set forth in claim 2 wherein the distance between the flanges on one of the front and rear walls is slightly less than the distance between the flanges on the other of the front and rear walls whereby the flanges on the one of the front and rear walls will be positioned within the confines of the flanges on the other of the front and rear walls.

4. The diffuser set forth in claim 2 wherein at least one corresponding pair of protrusions on the front and rear walls are hollow and open at their abutting ends, and wherein the means maintaining the front and rear walls in a position with their flanges overlapping includes bolt means extending through the open-ended protrusions.

5. The diffuser set forth in claim 2 wherein each of the protrusions is hollow.
