Abstract
A liquid delivery device for killing weeds. The liquid delivery device includes a main tube, a handle, and a pump housing that includes a pump chamber. A reservoir is disposed in the main tube, and a plunger is connected to the reservoir and positioned in the pump chamber. The plunger is operative to push a liquid contained in the pump chamber through a check valve and dispensing orifices when a user moves the reservoir with respect to the main tube and pump housing. The device also includes a spike extending from the pump housing and an annular stand-off surrounding the spike. The spike is adapted to disrupt the soil and damage the root structure of a target weed.
