METERING CAP Russian patent published in 2019 - IPC B65D51/28 B65D41/32 B65D81/32 B01F3/04 

FIELD: package and storage.

SUBSTANCE: invention relates to a container and its accessories, in particular, to a multi-chamber dosing cap intended, in particular, for dispensing a disinfectant composition. Dispensing cap comprises a body having a first end and a second end, at least one wall (10) forming first cavity (14) in the cap body, having a hole on a first end of the cap body, and, at least, one wall (12) forming second cavity (16) in the cap body, which also has a hole on the first end of the cap body. Separating element (18) is provided between first cavity (14) and second cavity (16), peripheral wall at first end of cap body and flexible seal (30) connected to peripheral wall at first end of cap body and with separating element (18) for isolation of contents of first cavity (14) from contents of second cavity (16). Seal (30) is less rigidly connected to separating element (18) than to peripheral wall, so that if critical pressure in cavities (14) and (16) is achieved, communication between seal (30) and separating element (18) is disturbed and enabling possibility of at least partial mixing of contents of first cavity (14) with contents of second cavity (16), while connection between seal (30) and peripheral wall remains intact. Cap also comprises rupture pin (20, 22) disposed in each of cavities (14) and (16), wherein each rupturing pin has a tip which presses against seal (30) and causes disruption of the connection between seal (30) and at least part of peripheral wall, when pressure applied to first cavity (14) and to second cavity (16), gradually increases beyond critical pressure limits.

EFFECT: technical result is faster formation of active agent and reduced delay to achieve adequate concentration of active reagent in main chamber.
