Abstract
The invention relates to a stopper capsule, having an axial direction, including a shell, with a head, a skirt, and a joint, where a) the joint is a form joint, b) the form joint has b1) a resilient layer, a set of adjacent layers, b2.1) a barrier layer, b2.2) a malleable support layer with the function of providing the set of adjacent layers a global malleable property such that the joint can be shaped without creation of folds, b2.3) an outer layer having an outer surface which can be compressed by the axial compression resulting from stoppering such as to match the form of the mouth of the neck. The invention further relates to a method of production of the capsule and a method of stoppering.
