发明名称 Device for liquid feeding of potted plants and the like
摘要 A device for the liquid feeding of potted plants and the like comprises an open end elongated tubular reservoir element for holding approximately one to four ounces of liquid. The element is of such length that a lower end portion thereof will be disposed in the root region of a plant when the element is embedded in the soil adjacent the plant. A top closure or cap element is provided and a bottom closure and absorption type transfer element projects upwardly and tightly fits the lower portion of the interior wall of the reservoir element. A continuous upwardly exposed surface on the absorption element receives liquid from the reservoir and the liquid is transferred through the element with the aid of gravity to a downwardly projecting portion thereof which has an exposed surface of reduced cross sectional dimension. The element has the general characteristics of the tip of a felt tip pen and transfers the liquid for absorption by the soil at a rate which provides for soil absorptive action over a period of at least several days.
