摘要： A radially expansible press plunger including a base plate and a first plunger skirt. A circumferential edge portion of the first plunger skirt is arranged at a guiding surface of the base plate and being arranged radially inward of the circumferential edge of the bottom surface. The first plunger skirt is resiliently transformable between an unexpanded state and a radially expanded state. The expansible press plunger further comprises a second plunger skirt having a plunger skirt side wall with a circumferential edge portion at a bottom end of the second plunger skirt and being arranged radially outward of the circumferential edge portion of the first plunger skirt. The second plunger skirt is resiliently transformable between an unexpanded state and a radially expanded state under influence from the circumferential edge portion of the first plunger skirt.

摘要： The present disclosure relates to a positioning unit for positioning a container element in a container body, comprising a base plate of a rigid material, and a plunger skirt of a resiliently deformable material. A footprint surface of the base plate has a circumferential edge with a side edge portion comprising an inwardly curved segment. The plunger skirt is transformable between an unexpanded state and an expanded state by relative movement in relation to the base plate.
The disclosure further relates to an attachment unit for attaching a container element to a container body and to an apparatus for attaching container elements to container bodies in a flow of containers. In addition, the disclosure relates to a method of positioning a container element in a container body by means of the positioning unit.
