Protective cap for dispensers and container comprising said cap

1. Device for dispensing fluids, comprising:

a dispensing head comprising:

i) a base able to be coupled stably to an outlet portion of a container;

ii) a dispenser having a dispensing outlet and slidably movable relative to the base to dispense a product contained in the container as a result of a pressure exerted on the dispenser;

wherein the dispenser presents a substantially cylindrical external conformation developing around an axis and also presents a first surface, defining a segment of a cylindrical surface with circular section which develops around said axis, and a second surface, defining a segment of an additional cylindrical surface with circular section also developing around said axis, the first surface having smaller radius than the second surface and said surfaces co-operating to define an outer contour of the dispenser,

wherein the two said surfaces are mutually joined by four shoulders transverse to said surfaces, each shoulder developing according to a helical path around said axis and defines a guiding surface developing according to a helical path around said axis, and

wherein said four shoulders are coupled in twos and each pair of shoulders has an angular position, around said axis, which is orthogonal with respect to the dispensing outlet of the dispenser;

and a protective cap designed to be applied on said dispensing head and comprising:

i) a base portion engageable to said dispensing head and presenting a hinging portion and a cylindrical body developing around a respective axis, said hinging portion being raised from the cylindrical body;

ii) a lid hinged to said hinging portion to rotate around an axis of rotation between an open position, in which the lid allows access to the dispensing head, and a closed position in which the lid prevents access to the dispensing head; and

iii) one outer locator plate engageable with any of said pair of shoulders of said dispensing head,

wherein said outer locator plate is borne by the hinging portion of said base portion and is defined by a projection extending towards the axis around which the cylindrical body of the base portion develops,

and wherein the mutual engagement between said outer locator plate and any of said pair of shoulders defines a screwing motion of the protective cap relative to the dispensing head to achieve automatically an installation of the protective cap on the dispensing head according to a pre-determined mutual angular positioning, wherein the protective cap is applied to the dispensing head with the hinging portion placed laterally with respect to the dispensing outlet of the dispensing head.

2. Container as claimed in claim 1 , wherein said outer locator plate and said shoulders are so shaped as to guide the cap automatically during an approach of the cap to the dispenser to make the cap assume said pre-determined angular positioning.

3. Container as claimed in claim 1 , wherein said outer locator plate and any of said pair of shoulders are mutually engaged by bearing relationship.
