Abstract: A membrane for use with a container is provided herein. The membrane comprises a first layer comprising a peripheral area defined by a first perimeter of the first layer, and a first line of weakness formed inward of the first perimeter. The first line of weakness defines a flap. The membrane further comprises a second layer comprising a peripheral zone defined by a second perimeter of the second layer and a second line of weakness formed inward of the second perimeter. The second line of weakness defines a central portion. The membrane further comprises a first seal area comprising at least a portion of the peripheral zone of the second layer being adhered to at least a portion of the peripheral area of the first seal area.

Abstract: A method, a shaping tool and a machine for assembling a tubular cardboard body (1) and a flat sealing structure (6), forming a security membrane, surrounded by a peripheral strip, able to be folded down, that is sufficient to suitably assemble the sealing structure with the inner lateral wall of the tubular body, with a grippable tongue (7) folded down toward the central part of the sealing structure, on the face not designed for sealing, inserting the sealing structure in a shaping tool and shaping it in the form of a basin, the peripheral strip becoming orthogonal to said central part, inserting the structure in the tubular body using said shaping tool, configured for sealing said strip with the exception of an unsealed part thereof, extending over the circumference of said strip.

Abstract: The invention relates to a method for manufacturing packages comprising a tubular body made from a cardboard material and a sealing structure made from a cardboard material, and machines implementing said method, comprising supplying a sealing unit (2) with preformed tubular bodies, two by two, and with sealing structures in the form of flat portions, two by two, each one comprising a central part with a shape conjugated to the shape of the opening of the tubular bodies, surrounded by a peripheral portion that can be folded down that is sufficient to assemble a sealing structure sealably with the inner side wall of the tubular body, inserting pairs of sealing structures into a forming tool (7), and forming them in a bowl, inserting, placing and sealing bowls in the tubular bodies using said forming tool; transferring, two by two, the tubular bodies assembled to the sealing structures to a finishing unit (10), if the sealing structure is a lid, precutting (14) the side wall of said tubular body and partiall
