DRIPPER INCORPORABLE IN A SINGLE - OR DOUBLE -WALL DRIP IRRIGATION PIPE MADE OF POLYMER WITH A BUMP THAT AUTOMATES THE OPENING OF HOLES ON THE IRRIGATION PIPE AND A DEVICE FOR OPENING SUCH HOLES

摘要

The invention at hand refers to a water dripping unit (dripper) that has all operational characteristics of hitherto known and used drippers intended to be incorporated in a single or double walled tube made of polymer material, yet it differs from such because it is equipped with an extension that has a proper cut made next to the water exit. This extension, along with the part of the irrigation tube that surrounds it, is cut off during the production process by a proper layout of an ambient or stable cutting knife or instrument or otherwise, thus creating the hole in the tube's wall that permits communication of the water exit chamber with the surrounding space. This drilling is done simply during the passing of the extension through the cutting device, without need of expensive and complex electronic devices that would determine the exact location of the hole and would activate the drilling device, and without the possibility of any drilling taking place or drilling made in a wrong location that would result in a faulty irrigation tube.
