The cap (4) has a spraying orifice (7) whose external end includes a tapered shape or tapered shape part e.g. frustoconical part, with point directed towards a direction of a spray. An external envelope of the tapered part has a groove (5) of depth sufficient to constitute an outlet channel for fluid when the cap is inserted in an animal or human physiological channel as an auditory conduit of a mammal.
