Closure with device for discharging liquid from bottles may be used countlessly and set onto the bottles of different sizes and shapes. The closure (1) is activated by a handle (15), that moves a sliding valve (14). The sliding valve (14) encloses a body (17) of the sliding valve a piston rod (21) and a piston (22). The piston (22) is coupled to a key (24), which is inserted into a groove (30) in a valve (8) for admission of air into the bottle with liquid. By moving the sliding valve (14) a pass-through (55) releases the flow of the liquid from the bottle through an opening (11) and a channel (12). Moving of the piston (22) with the key (24) with programmed delay draws the valve (8) as well, so that admission of air is allowed and so the air from the atmosphere goes into the liquid that is being discharged. The whole closure is done in plastic mass.
