  • Patent number: 11007546
    Abstract: A child-proof discharger for media includes a reservoir, a pump part mounted on the reservoir and an actuable discharge portion mounted on the pump part. The discharge portion guided in an axially displaceable manner on a carrier part disposed on the closure element and can be locked with the aid of manually actuable spring bars. The spring bars are configured on an actuating plate configured on the discharge portion, and respectively have an inner tongue, which can be bent radially inwards relative to an inner wall of the carrier part. Each spring bar is respectively assigned a guide ramp as an entry curve to a contact area that is bounded by radial latches of the blocking setting upon a rotary motion of the discharge portion.
