A container comprises a dispensing head (13) and a protective cap (1) fitted on the dispensing head (13). The cap (1) comprises a base portion (1a) engageable to a dispensing head (13); a lid (1b) hinged to said base portion (1a) and movable between an open position, in which it allows access to the dispensing head (13), and a closed position in which it prevents access to the dispensing head (13); an outer locator plate (9) engageable with a corresponding inner locator plate (24) of said dispensing head (13), the mutual engagement between said locator plates (9, 24) defining a screwing motion of the cap (1) relative to the dispensing head (13) to automatically achieve an installation of the cap (1) on the dispensing head (13) according to a pre-determined mutual angular positioning. The dispensing head (13) comprising a base (14) able to be coupled stably to an outlet portion of the container; a dispenser (15) having a dispensing head and slidably movable relative to the base (14) to obtain a dispensing of a product contained in the container as a result of a pressure exerted on the dispenser (15); at least one inner locator plate (24) engageable with the outer locator plate (9) of the cap (1), to guide the outer locator plate (9) according to a helical path around the dispenser (15).
