摘要:
A water-drip hose comprises: the first fusion splicing units formed to have an upper fusion splicing line parallel to an end portion of the outer film, a lower fusion splicing line shorter than the upper fusion splicing line, and side fusion splicing lines of a smooth curved shape for connecting the upper fusion splicing line with the lower fusion splicing line two second fusion splicing units respectively formed at a lower position between the first fusion splicing unit and a neighboring first fusion splicing unit in parallel to the lower fusion splicing line of the first fusion splicing unit at regular intervals, which forms three lower openings and a third fusion splicing unit formed at an upper position between the first fusion splicing unit and the neighboring first fusion splicing unit in parallel to the upper fusion splicing line of the first fusion splicing unit, which forms two upper openings.
