Dispenser for dispensing a fluid

A dispenser (1) for dispensing a fluid contained in a bottle, made of plastic material, comprising:

• a connecting element (2) comprising an assembly portion which can be screwed on the neck of a bottle;
• a suction and pumping apparatus (3) connected or connectable to said connecting element (2) and configured for drawing a fluid from said bottle;
• a dispensing head (4), slidably coupled to said connecting element (2) and connected below to said apparatus (3) and equipped with a channel designed to collect the fluid flowing out from said apparatus (3) and dispense it through an outlet channel (5), said dispensing head (4) being configured for activating and deactivating, by means of a rotation of said dispensing head (4), a locking mechanism designed to define an operating configuration of the dispenser (1), wherein said dispensing head (4) can be pressed by a user to operate said apparatus (3) and allow the outflow of the fluid through said outlet channel (5), and a non-operating configuration of the dispenser (1), wherein said dispensing head (4) cannot be pressed to operate said apparatus (3);
• characterised in that said connecting element (2) comprises at least one flexible profile (6), defined along a circular sector of said connecting element (2), having at least a first free end and at least one anchoring peripheral portion, stably fixed to said connecting element (2);
• said dispenser (1) also comprising at least one rib (7) extending at least partly inside said circular sector of said connecting element (2);
• said at least one rib (7) being active, in use, by means of said rotation of said dispensing head (4) associated with said locking mechanism, in contact against said first free end of said flexible profile (6) in such a way as to reduce and/or permanently deform said flexible profile (6).
