Substance dispenser, especially for medical or cosmetic treatment

摘要

A dispenser containing a substance to be applied on a patient is described. The dispenser includes a plunger, a tube and a perforated element located inside the tube. The tube contains openings at its application end. When the plunger is pushed during application, the substance is squeezed through the perforated element and the openings and is applied to the patient. Selection of the height of the perforated element and presence or absence of alignment between the perforations of the perforated element and the openings allows control of the application of the substance on the patient.
