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.
