Abstract
A dosage-dispensing head has a body with an end surface and an area that couples the head to a source container. The end surface has an outlet opening connected to the coupling area. The head also has a slider, constrained to a guided linear sliding movement parallel to the end surface. An aperture-setting member of the body turns about a rotary axis, orthogonal to the end surface, to actuate the slider. An orifice opening of the aperture-setting member is configured so that the outlet opening is always within the area of the orifice opening. A passage opening of the slider is between the body and the aperture-setting member. By turning the aperture-setting member, the slider moves in a linear path, linearly displacing the passage opening relative to the outlet opening and varying the aperture width of the dosage-dispensing head. This regulates the flow rate of the free-flowing dosage material.
