Dispenser closure for a container that contains a flowable product

Abstract

The invention relates to a dispenser closure ( 10 ) for a container that contains a flowable product, especially for a beverage container. Said dispenser closure comprises: a closing body ( 100 ) with a cover ( 120 ) from whose outer rim a jacket ( 110 ) extends downward that can be fastened via an opening of the container on the same, an outlet opening ( 126 ) in an upper face of the closing body ( 100 ), which communicates with the opening of the container, and a closure element ( 200 ) for opening or closing the outlet opening ( 126 ) of the closing body ( 100 ), and a dome-shaped raised section ( 124 ) of the closing body ( 100 ), which is disposed around the outlet opening ( 126 ) of the closing body ( 100 ). The closing body ( 100 ) is provided with a covering element ( 150 ) that covers at least partially an outer area of the dome-shaped raised section ( 124 ), the material of the covering element ( 150 ) being softer than the material of the dome-shaped raised section ( 124 ) and/or the cover ( 120 ) and/or the material of the closing body ( 100 ). The invention allows for an increased tightness of the dispenser closure and a pleasant feel when the user comes into direct contact with the dispenser closure.
