  "abstract": "The invention relates to a vacuum cup ( 1 ) that is able to ensure a very silent release of an object that is being held by the vacuum cup ( 1 ). The vacuum cup ( 1 ) comprises a channel ( 7 ) that allows a fast passage of ambient air into a vacuum chamber ( 3 ) to bring the vacuum chamber ( 3 ) to atmospheric pressure. Preferably, the channel ( 7 ) comprises openings ( 9, 9′, 13 ) that have surface area's being large compared to the surface area of a top ( 10 ) of the vacuum chamber ( 3 ) in order to obtain a fast release.",
