Abstract

An opening device for a packaging container comprises two operational parts: a membrane part ensuring a secure seal of the packaging container and a support part ensuring rigidity for the opening device. The opening device is characterized in that a membrane portion of the membrane part is mechanically attached to the support part to operate as one piece during opening of the packaging container, and the materials of the membrane part and the support part are thermally incompatible.
