Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
A plant watering device comprising; a reservoir for placement on the soil proximate to a plant, said reservoir being replaceable and frictionally engageable with a pointed, cylindrical soil penetrating member, said penetrating member constructed of an outer porous material and having a center sleeve, said center sleeve formed of a liquid impervious material and having a longitudinal opening along its entire length, said penetrating member and said reservoir being interconnected by a joint which allows pivoting of the reservoir obliquely relative to said soil penetrating member whereby said penetrating member can be inserted into the soil at a desired angle to said reservoir and said reservoir can remain in a stationary position on the soil for allowing a controlled flow of liquid to pass from said reservoir through the longitudinal opening of the center sleeve and through the outer porous material and into the soil.
