Abstract
A radially expansible press plunger has a base plate, a first expansion tool and a second expansion tool. The first expansion tool and the second expansion tool are movable in relation to each other in the axial direction. The first expansion tool has at least one inclined plane surface. The second expansion tool has at least one inclined plane surface corresponding to the at least one inclined plane surface on the first expansion tool. Each inclined plane surface on the first expansion tool contacts and applies pressure to the corresponding inclined plane surface of the second expansion tool when the expansible press plunger is in the radially expanded state. An attachment unit for attaching a container sealing element to a container body and a method for attaching a container sealing element to a container body are also disclosed.
