Outlet spout for cartridge system, has perforation unit with cutting edge, formed from intersection line of inlet front surface, and inlet pipe socket expanding behind edge, so that breakthrough opening of container stretches around socket

摘要

The spout has a fluid outlet running from an inlet (5) to an outlet opening (6). A perforation unit that pierces through a fluid container is designed at an inlet pipe socket (2). The socket has an outer peripheral surface, and an inlet front surface that is tilted in an acute inclination angle opposite to a longitudinal axis of the socket. The unit has a cutting edge, which is formed from an intersection line of the front surface with the outer peripheral surface. The socket expands behind the edge, such that a breakthrough opening of the container stretches closely around the socket.
