Capsule for tightly Sealing plugging a neck of a container by axial Compression and lateral Capsule and a Board against the neck,Includes a helmet with a head and Skirt, and a GASKET disposed in the Interior of the

摘要

The cap (1') has a shell (2) and a multilayer joint (3) with a metal layer forming a barrier against gas diffusion. A malleable support layer provides, adjacent set of layers, a malleable global mechanical behavior permitting, in association with a resilient layer, the joint to be subjected to deformation imposed by shaping the joint without formation of folds. An external layer in plastic material has an external surface to be indented under an axial compression effect of the cap and the joint against a neck such that the external surface mates with a widemouthed surface of the neck. The joint is free from a layer in a cellulosic material or in paper e.g. kraft paper. Independent claims are also included for the following: (1) a method for manufacturing a sealing cap (2) a method for capping a neck of a bottle.
