摘要

Liquid weedkiller applicator for lawns is easy to handle and works on the spot by spot eradication principle. A chamber walled in semi-stiff transparent polyethylene stocks the weedkiller fluid and connects to a porous pad of foamed polyester of sufficient section to allow fluid out onto the weed when the pad is contracted and reexpanded a valve in the chamber seal consists of an orifice in a screw cap and an orifice in an inside flange on a screw connector, so that with the cap screwed home the orifices lie out of contact. Only by partly unscrewing the cap can be orifices be lined up to control air entry to the chamber. Specifically, the pad and chamber are coupled by a cylindrical extension of the chamber wall, and the pad is held in place by a retainer ring fixed on the outside of this extension piece.
