CLOSING AND DOSING DEVICE, DOSED LIQUID DISPENSING SET Russian patent published in 2009 - IPC B65D47/20 

FIELD: mechanics.

SUBSTANCE: closing and dosing device for liquid products includes base element of closing device containing main cover with skirt to be fixed to container neck, flexible dosing valve made from resilient elastomer, clip to fix dosing valve to base element and fully flap lid to be connected with base element so that it can be rotated between closed position when main lid is closed, and open position, when lid is at a distance from the main lid. The main lid is provided with recess that contains the first circular wall coming from the main lid within skirt limits and the second circular wall coming in radial direction inwards from the first circular wall to the location and at a distance from the main lid, the third circular wall is directed to the main lid from the inner periphery of the second circular wall. The clip is provided with the flat circular lid and the first circular wall coming from the external periphery of the circular lid and being engaged with the third circular wall on the base element to fix clip and valve to the base element. Dosing valve contains peripheral part to be compressed between the said clip and the third circular wall, and a central part with at least one slot for dosed dispensing. The external surface of the circular clip lid is made flush with the external surface of the main lid in the base element in closing device. The clip is also provided with the second circular wall coming from the periphery of the flat circular lid. The lid itself includes internal wall for engagement with the second circular wall on the clip to retain lid in closed position. A set for dosed liquid dispensing is also provided.

EFFECT: new design of closing and dosing device avoiding possibility of clip and valve removal from base element and facilitating cleaning of the main lid in closing device.
