Abstract
A dispenser of fluid products includes a ring nut (2) able to be associated to a container of a fluid product and a substantially hollow dispensing head, able to slide coaxially relative to the ring nut (2); the dispensing head (8) includes a dosing chamber (14) obtained within the dispensing head (8) and a dispensing nozzle (12) to allow the outflow of the fluid product; the dosing chamber (14) has a containment volume variable between a configuration of maximum volumetric capacity when the dosing chamber (14) is isolated and a configuration of minimum volumetric capacity; the dispenser further includes a deformable membrane (15) fastened to the ring nut (2) and a deformable disc-shaped body (16) fastened to the dispensing head (8) and defining the dosing chamber (14) in combination with the membrane (15).
Claims18
Dispenser of fluid products comprising a ring nut (2) able to be associated to a container of a fluid product;
- a substantially hollow dispensing head (8) able to slide coaxially relative to said ring nut (2);
- said dispensing head (8) comprising a dosing chamber (14) obtained inside said dispensing head (8) and a dispensing nozzle (12) to allow the outflow of said fluid product;
- said dosing chamber (14) having a containment volume that can vary between a configuration of maximum volumetric capacity when said dosing chamber (14) is isolated and a configuration of minimum volumetric capacity;
- said dispenser being characterised in that it further comprises a deformable membrane (15) fastened to said ring nut (2) and a deformable disc-shaped body (16) fastened to said dispensing head (8) and defining said dosing chamber (14) in combination with said membrane (15);
- wherein said membrane (15) presents an upper edge (15b) in contact with a lateral edge (16a) of said disc-shaped body (16) when said dispensing head (8) is in said first position to isolate said dosing chamber (14);
- said upper edge (15b) being moved away from said lateral edge (16a) of said disc-shaped body (16) during a passage from said first position to said second position of said dispensing head (8) to allow fluid communication between said dosing chamber (14) and said dispensing nozzle (12).
