APPLICATOR DEVICE OF HANDLE-PRESSING TYPE AND METHOD FOR ITS USE Russian patent published in 2016 - IPC A61M35/00 A61M5/315 A45D34/04 A46B11/02 

FIELD: medical equipment.

SUBSTANCE: group of inventions refers to medical equipment, and concerns applicator device of handle-pressing (clicking) type for dispensing composition, and method for using applicator device of handle pressing type. Disclosed device comprises central area, applicator section, located at distal end of central area; and also multistage section of actuator located at proximal end of central area. Central area has proximal end and distal end, and forms storage section, wherein composition is located. Disclosed multistage section of actuator is made with possibility of filling by means of pressure upon dispensing mechanism having piston seat with two sets of external threads on axis, between which non-threaded segment is located. Method for filling and dosing composition by means of dispenser of handle-pressing type comprises steps whereat: composition is poured at filling rate, using actuator having seat of piston with two sets of external threads on axis, between which non-threaded section is located; and dosed composition at rate of dosing, different from rate of filling, using pressure actuator. Method for dispensing composition using said device comprises steps whereat device is poured by filling starts of actuator multistage section, filling step therein contains start of general filling, displacement of volume, exceeding volume of specified dose; output specified dose of composition by applicator section, via subsequent operation of output from actuator multistage section; and specified dose is applied via applicator section.

EFFECT: inventions allows improving tightness of storage of composition for reducing evaporation and/or weight loss, providing specified dosing of composition for accurate application, as well as fast filling composition for preparation of applicator to immediate use.
