An ejection head for an ejection device of a sealing machine for sealing a container includes a supporting element with a supporting axis and a sliding end, and a sliding element for sliding the supporting element along a sliding profile of the sealing machine. The sliding element is arranged at the sliding end and a force acting essentially in the direction of the supporting axis is capable of being transmitted via the sliding element to the supporting element. So that the sliding element and the sliding profile are subject to reduced wear, the sliding element is a rotatable rolling element, so that in the operating state the supporting element is capable of being unrolled over the rotatable rolling element along the sliding profile.
