摘要
This device comprises: a container defining an inner volume intended to contain the product closed off by a movable bottom and opening out through a dispensing neck; a dispensing member; a purge ring comprising a base that delimits a central orifice defining a central axis of the ring, the base having an outer contour and a side surface converging from the outer contour toward a second end of the central orifice. The device is characterized in that the purge ring comprises at least one radial opening arranged radially relative to the central axis and allowing the passage of the product from the container toward the central orifice.
