Abstract
A drip irrigation unit, comprising: a bottom, generally cup-shaped, member having a bottom member base in which a plant-inserting opening is defined, a peripheral closed-loop wall extending upward from a peripheral edge of the bottom member to a first apex, and an internal closed-loop wall extending upwards from a peripheral edge of the plant-inserting opening to a second apex that is lower than the first apex, the peripheral and internal walls being integral with the bottom member base and defining a water reservoir, and a top member having an aperture and a rim, an annular surface defined between the rim and the aperture being downwardly sloped towards the aperture and defining a generally funnel-shape, the top member being connectable to at least one of the first or second apexes, such that the plant-inserting opening and the aperture become aligned, the internal closed-loop wall having at least one perforation vertically distanced from the bottom member base, the at least one perforation defining a water flow path from the reservoir to the plant-inserting opening.
