Abstract
An attaching ring or fixing ring is provided for attaching or fixing a dispenser member to a neck of a receptacle containing a substance to be dispensed. The ring is annular and has a bottom portion and a top portion. In a preferred embodiment, the bottom portion includes snap-fastening tabs for fixing the ring to the neck. The top portion includes an opening for the dispenser and a surrounding structure for securing the dispenser member to the neck. The top portion further includes at least one guide wall element extending parallel to the longitudinal axis of the dispenser member and around the periphery of the fixing ring substantially in line with the snap-fastening tabs. A hoop can be provided for preventing the tabs from splaying apart. The hoop can include an internal projection, such as a vertical rib or a thread.
