Abstract: A dispenser (1) with a hermetic seal includes a hollow containment body (2) which can be inserted in a bottle, a lower suction tube (5), a piston (7) slidable inside the containment body (2), a hollow stem (6) axially slidable inside the containment body (2), a sealing valve (8) inserted in a bottom portion (4) of the containment body (2) and interposed between the suction tube (5) and the dosing chamber (11). The sealing valve (8) is cup-shaped and the piston (7) has a lower sealing portion (7b) configured in such a way as to interact in compression with an upper edge (8a) of the sealing valve (8) making a hermetic seal between the sealing valve (8) and the piston (7).

Abstract: Described is a dispenser for dispensing a fluid contained in a plastic bottle, including a ring nut having a cylindrical conduit for sucking the fluid; a concertina-like deformable element including side walls defining a dosing chamber; a ring identifying with the ring nut a locking system defining an operating and non-operating configurations; a dispensing head, which can be pressed by a user and having a collection chamber collecting the fluid flowing from the dosing chamber through a central opening of the ring; first and second shutoff elements defining, respectively, a check valve at the inlet and a check valve at the outlet of the dosing chamber; a locking element interfering with at least one between the first and the second shutoff elements to lock it in the fixed position and thereby occlude the suction conduit and/or the central opening in a stable manner at least in a dispensing configuration.

Abstract: A fluid dispenser includes a ring nut to be screwed on a bottle neck and including a shoulder and a collar extending in elevation from the shoulder. It also includes a dispensing head including a central portion, a spout designed to dispense the fluid contained in the bottle and a protective skirt extending to contain the collar of the ring nut. The protective skirt extends close to a peripheral portion of the shoulder and, in a closed configuration of the dispenser, has a safety distance from the shoulder. The dispensing head includes a cylindrical crown shaped to form a toothed profile and located between the protective skirt and the central portion. The ring nut collar includes gripping elements with a longitudinal extension and the toothed profile engages the gripping elements when closed. The toothed profile and the gripping elements are shaped to allow reciprocal rotation of the dispensing head.

Abstract: Described is a dispenser for dispensing a fluid, made of plastic material, including: —a ring nut having an inner cylindrical wall equipped with partial grooves; —a concertina-like deformable element, defining a return spring of the dispenser and including a cylindrical lower projection equipped with relative partial grooves; —a ring designed to define with the ring nut a locking system designed to define an operating configuration and a non-operating configuration of the dispenser in such a way as to pull the concertina-like deformable element in such a way as to align the partial grooves of the cylindrical wall of the ring nut and the partial grooves of the concertina-like deformable element.
