Abstract:
1. A communicating duct for a container, comprising: at least one tubular element anchorable to an outlet portion of a container to create at least one spout having a passage between the container and the surrounding environment; and at least one connecting portion having at least one connecting area such as can be united hermetically with the outlet portion of the container, the connecting portion having an internal bridging surface forming a bottom surface of the communicating duct disposed substantially normal to the longitudinal axis of the tubular element that contacts a fluid contained within the container at least when pouring the fluid from the container; the internal bridging surface having an external periphery and an internal periphery; the external periphery being a bottom edge of a radially outward facing external peripheral surface for contacting the container around an entire periphery of an interior surface of the outlet portion of the container; the internal periphery being a bottom edge of an entire circumference of an internal opening of the passage of the spout; the internal bridging surface being a flat, uninterrupted and free-flowing surface covering an entire area extending between the external periphery and the internal periphery and being free of structure that can cause at least one of fluid stagnation and accumulation; the at least one connecting area comprising a plurality of connecting surfaces substantially flat and equal to a number of side walls of the outlet portion; the connecting portion including at least one locating element extending transversely relative to the connecting area and positioned to engage in abutting contact with a terminal edge of a respective side wall of the outlet portion of the container axially above the internal bridging surface; wherein each connecting surface establishes at least one corner edge positioned facing a respective internal corner formed between two side walls of the outlet portion of the container, the connecting portion including, for each corner edge, a relative radially cantilevered projection extending between two seams of a respective joined area of the outlet portion, each projection presenting a substantially flat and slender profile to be inserted between the seams of the outlet portion and to be bonded with such seams.
