System for Handling of Liquids

Abstract

A device for storing and delivering liquids comprising a watertight bag having at least one opening and a delivery system operatively connected to said opening; the device further comprises a first and second stiff surfaces connected by flexible flanks. The delivery system comprises a connection locking device for connecting the fluid-carrying pipes and fitting system, which comprises a spigot inserted in the collar of a hose, an external compression ring positioned onto the portion of the collar which is covering the spigot and a conical threaded sleeve locking said external compression ring onto said portion of the collar covering the spigot.
