Abstract: An articulated structure to connect a cover to a support, which may be installed on a container or is formed from a single piece with an opening section of the container, comprising an articulated joint to guide the cover between a closed position and an open position with a pivot point situated on the outer side of the cover and/or the support, and an elastomer spring part, which grips the outer side of the cover as well as the support and is prestressed at least in the closed position of the cover under tension, characterized in that a force application point of the elastomer spring part to the cover and/or to the support at least in the closed position of the cover is displaced to the outside beyond the pivot point of the articulated joint.

Abstract: The invention relates to a closure device (100; 200; 300), for fitting to an opening (41) of a fluid product reservoir (4), said device being embodied in a monobloc form by injection/molding of plastic material and comprising a fixing body (110; 210; 310) for cooperation with the opening on the reservoir to produce a sealed fixing, a distribution duct (120; 220; 320), forming an outlet passage (121; 221; 321) for the fluid product contained within the reservoir, said duct forming a distribution opening (122; 222; 322), a closing body (13; 23; 33), for sealing said duct, said closing body being connected to the distribution duct (120; 220; 320) by means of at least one link of material (132; 232; 332), designed to break on the first withdrawal of the closing body.

Abstract: A fluid dispenser head for associating with a fluid reservoir (1), the head having: a stationary base (2) formed by, or for mounting on, the reservoir; a rotary actuator element (3) mounted in rotary manner on the base (2) so as to turn about an axis of rotation between two extreme abutment positions; and a dispenser orifice (30) that can be closed selectively by turning the element on the base. The two extreme abutment positions define two open positions of the dispenser orifice separated by at least one position in which the dispenser orifice is closed. The dispenser orifice (30) is situated on the axis of rotation of the element on the base.

Abstract: The inventing fluid product delivering head is mounted on the orifice of a fluid product container and comprises a control flap (16, 21, 22) elastically displaceable between a closed position wherein said fluid product is unable to flow from the container through said head and an opened position which enables the fluid product to flow through the head, and a control unit (25) manually actuatable in order to move the control flap from the closed position thereof to the opened position, at least one structural element of the head being produced by comoulding two types of different plastic materials. The inventive head is characterised in that it comprises a base (1) and a cap (2) forming the first flap part (16) and second flap part (21, 22), respectively which interact with each other in such a way that the control flap is formed thereby.
