Abstract
Apparatus for selectively applying a liquid plant chemical such as a herbicide to a plant includes a hollow tubular reservoir, an integrated funnel handle at the upper end of the reservoir, and an applicator tip at the lower end of the reservoir. The applicator tip includes a valve and a wick that allows the chemical to be dispensed in a controlled manner onto a specific plant, avoiding chemical drift. A protective cap fits over the applicator tip during storage, while retainer tabs keep the protective cap from squeezing the wick. The retainer tabs may be sharp enough to prick the plant to place the chemical internally.
Claims15
An apparatus for selectively applying a liquid plant chemical to a plant, comprising:
- a hollow tubular reservoir having upper and lower ends and a reservoir diameter;
- a handle disposed at the upper end of the reservoir;
- a reservoir cap disposed at the top of the handle, whereby the reservoir may be opened for the insertion of the plant chemical into the reservoir and closed;
- an applicator tip disposed at the lower end of the reservoir, the applicator tip comprising a normally closed pressure-sensitive valve and a wick;
- and
- a protective cap adapted to cover the applicator tip during periods of non-use;
- wherein the applicator tip is placed against the plant to actuate the valve to dispense the plant chemical onto the wick for selective transfer to the plant.
In a cane-type selective plant chemical applicator comprising a hollow-tube reservoir having upper and lower ends and a reservoir diameter, a handle disposed at the upper end, and an applicator tip disposed at the lower end and having a pressure-sensitive valve and a wick for contacting a plant to dispense a plant chemical thereto, the improvement comprising:
- the provision and constitution of the handle as a funnel handle integrated with the reservoir and flared between a lower diameter equal to the reservoir diameter and a substantially wider upper diameter, to facilitate spill-free insertion of the plant chemical into the reservoir.
