Abstract:

The automatic watering pot is a flower pot with an automatic watering device for dispensing water into the soil at or below the root level of a potted plant. The automatic watering device has a bottle which serves as a water reservoir, a cap for the bottle having a rotary valve, a delivery tube inserted into the cap, and a dispersion fitting at the free end of the delivery tube. The automatic watering device is disposed with the bottle inverted above the level of the soil, the delivery tube extending into the soil, and the dispersion fitting to a depth equal to or below the level of the roots. The bottle is made from a translucent or transparent material, and may have a float so that the water level may be visually discerned. The cap has a rotary valve so that the flow of water from the bottle to the delivery tube may be cut off by rotating the cap when it is necessary to refill the bottle. The dispersion fitting has a plurality of pinhole orifices which serve to provide a path for water to flow from the tube into the soil, for air to enter the tube, and as a filter to prevent soil particles from entering the bottle.
