  • Patent number: 6443368
    Abstract: A gardening applicator for efficiently delivering liquid chemicals to selected vegetation is disclosed. The applicator includes a wind guard chamber through which a stream of emitted liquid chemicals may be directed in a predetermined path along a central axis of the wind guard chamber. The wind guard chamber is preferably tube shaped over a predetermined length and can incorporate a diffuser screen or mesh which extends transversely across the predetermined path at the exit end of the wind guard chamber such that the liquid chemicals are finely dispersed upon passing through the diffuser screen. Actuation of a pressure activated pump head may provide a pressurized stream of liquid chemicals through the wind guard chamber and onto the diffuser screen where it is dispersed in a uniform circular pattern onto selected vegetation. The pressure activated pump head may conveniently be connectable to a liquid chemical reservoir such as a generally commercially available bottle with a standard sized threaded opening.
