Abstract

Abstract A plant irrigation device for a potted plant includes a hollow stake adapted to be inserted into the soil adjacent to the plant, and a bottle supported on the stake in an inverted position. The bottle is provided with a dispensing cap which has a spout extending down into the hollow stake, and which causes liquid contained in the bottle to drip down through the stake into the soil. A replaceable disc-shaped filter is mounted in the cap which filters sediment out of the liquid through the spout, and which serves to prevent clogging of the spout. The filter also acts as a restrictor which causes the liquid to drop slowly from the bottle as a function of the quantity of filter material in the cartridge.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 174 words
A device for irrigating the soil of a plant over an extended period of time, said device including: a bottle having a neck of reduced diameter compared with the diameter of the bottle; a dispensing cap attached to the neck of the bottle and removable to permit the bottle to be filled with liquid, said dispensing cap having a spout; a hollow stake-like member adapted to be inserted into the soil in an upright position and serving to support the bottle in an inverted position above the surface of the soil with said spout extending into the top of the stake-like member and for causing liquid from the bottle to drip down through said stake-like member into the soil; a porous disc-shaped member of filtering material having a diameter corresponding to the reduced diameter of the neck removably mounted in said cap to form a wall between the neck and the cap and serving to remove sediment from the liquid and to prevent clogging and to restrict the flow of liquid through the cap.
Claim 2
Independent Claim 174 words
A device for irrigating the soil of a plant over an extended period of time, said device including: a bottle having a neck of reduced diameter compared with the diameter of the bottle; a dispensing cap attached to the neck of the bottle and removable to permit the bottle to be filled with liquid, said dispensing cap having a spout; a hollow stake-like member adapted to be inserted into the soil in an upright position and serving to support the bottle in an inverted position above the surface of the soil with said spout extending into the top of the stake-like member and for causing liquid from the bottle to drip down through said stake-like member into the soil; a porous disc-shaped member of filtering material having a diameter corresponding to the reduced diameter of the neck removably mounted in said cap to form a wall between the neck and the cap and serving to remove sediment from the liquid and to prevent clogging and to restrict the flow of liquid through the cap.
Claim 3
Dependent Claim 18 words
The device defined in claim 1, in which said porous disc-shaped member is formed of a plastic material.
Claim 4
Dependent Claim 37 words
The device defined in claim 1, and which includes an annular gasket positioned in said cap between said porous disc-shaped member and the neck of the bottle and engaging the peripheral surface of said porous disc-shaped member.
Claim 5
Dependent Claim 18 words
The device defined in claim 2, in which said cap is threaded to the neck of the bottle.
