Abstract: A discharge head for a liquid dispenser having a base, an actuation handle, a liquid inlet and a discharge opening. The discharge head has a pump mechanism which conveys liquid from a liquid store to the discharge opening. To control liquid to be discharged and/or inflowing air, the discharge head has a valve with a valve flap which closes a valve channel and transfers to an open position by a positive pressure that exceeds a threshold positive pressure. The discharge head has an effector element bearing on the handle and the base, which deforms when the handle is pressed down. The valve flap is designed and attached to the effector element such that the deformation of same acts on the valve flap so that the threshold positive pressure, beyond which the valve flap leaves its closed position, is at least 10% lower in an actuated end position than in a non-actuated end position.

Abstract: A discharge head for discharging liquid as an atomized spray jet and as a non-atomized liquid stream or as individual droplets. The discharge head fastening fastens to a base unit and has a liquid outlet through which liquid is discharged from a reservoir into the atmosphere, and a liquid inlet through which liquid is conducted out of the reservoir to the liquid outlet. An internal part is arranged inside an outlet channel, and a spray opening is provided on the internal part. The internal part and the outlet channel are relatively displaceable so that in a first position a bypass duct is produced between an internal wall of the outlet channel and an outer face of the internal part, the flow resistance thereof being lower than the spray duct, and in a second position is partially closed wherein the flow resistance of the bypass duct is greater than the spray duct.
