Abstract

An applicator for introducing a fluid to a plant includes a first arm and a second arm pivotally connected to one another at one end. The other ends are spaced apart to receive the plant therein when the applicator is in a rest position and are driven together upon pivoting of the arms to place the applicator in an application position. A fluid injector is mounted on the first arm and includes an injector body and a diaphragm defining a plurality of channels. The diaphragm includes a pliable dome defining a reservoir to receive the fluid and a plurality of applicator nodes. A respective applicator node is positioned near a terminus of each channel. A driving member engages the pliable dome when the applicator is pivoted to the application position. The pliable dome is then compressed by the driving member to direct the fluid through the plurality of channels.

First claim

What is claimed is:

1. An applicator for introducing a fluid to a selected portion of a plant, the applicator comprising:
a) a first arm having a first end and an opposing second end;
b) a second arm having a first end and an opposing second end, wherein said first ends are pivotally connected to one another, and wherein said opposing second ends are spaced apart so as to receive the selected portion of the plant therein when the applicator is in a rest position and wherein said opposing second ends are configured to be driven together upon pivoting of said first and second arms to place the applicator in an application position;
c) a fluid injector mounted on said opposing second end of said first arm, said fluid injector comprising:
i) an injector body; and
ii) a diaphragm coupled to said injector body and defining a plurality of covered channels therebetween, said diaphragm including a pliable dome defining a reservoir configured to receive an aliquot of the fluid and a plurality of applicator nodes, wherein a respective applicator node is positioned proximate a terminus of each respective covered channel of said plurality of covered channels; and

d) a driving member mounted onto said opposing second end of said second arm and configured to engage said pliable dome when the applicator is pivoted to said application position, wherein said pliable dome is compressed by said driving member to direct the aliquot of the fluid through said plurality of covered channels and out of each respective applicator node.

2. The applicator in accordance with claim 1 wherein each of said plurality of applicator nodes includes a perforation.

3. The applicator in accordance with claim 1 wherein said opposing second end of said second arm further includes a plurality of piercing elements, wherein a respective piercing element is configured to be positioned proximate said terminus of each respective covered channel when the applicator is in said application position, and wherein each piercing element of said plurality of piercing elements is configured to form a respective puncture within said selected portion of said plant before said aliquot of the fluid is directed to each respective applicator node.

4. The applicator in accordance with claim 3 wherein said fluid injector further includes a plurality of guide members, wherein a respective guide member is positioned proximate said terminus of each respective covered channel, wherein each respective guide member is configured to receive a respective piercing element therein when the applicator is in said application position and direct said aliquot of the fluid to each respective puncture within said selected portion of said plant.

5. The applicator in accordance with claim 1 and further comprising:
e) a cartridge removably coupled to said first arm and in fluid communication with said reservoir defined by said diaphragm.

6. The applicator in accordance with claim 5 wherein said fluid injector further comprises:
iii) an injector valve between said cartridge and said diaphragm, wherein said injector valve allows flow of said fluid from said cartridge to said reservoir when the applicator is in said rest position and prevents reverse flow of said fluid from said reservoir to said cartridge when the applicator is in said application position.

7. The applicator in accordance with claim 1 wherein said first arm and said second arm are a continuous unitary construction.

8. The applicator in accordance with claim 1 and further comprising:
e) a cap configured to mount on said opposing second ends of said first and second arms, wherein said cap holds said applicator in said rest position and prevents pivoting of said first and second arms to said application position.
