METHOD FOR PRODUCING A LAMINATE FOR MAKING CLOSING ELEMENTS FOR CONTAINERS OR RECEPTACLES, LAMINATE AND CONTAINER

摘要

A container including a containment wall, defining an internal containment volume and including a free edge, a closing element including a welding layer welded onto the free edge of the wall and a front layer defining an outer surface of the container. An intermediate layer of removable self-adhesive is spread onto an adhesion portion of mutually coupled surfaces of the welding layer and front layer. An opening line adapted to define an access window is obtained through an incision in a stretch of thickness of the welding layer splitting the welding layer into a welding portion adapted to be welded to the container and an opening portion corresponding to the access window, with reference to an assembled configuration on the container. The incision is made to allow the detachment of the opening portion from the welding portion while the closing element is opened.

主权项

1. A method for producing a laminate for making closing elements for containers or receptacles comprising at least one first layer or welding layer adapted to be welded to a free edge of the container and at least one second layer or front layer for example adapted to define an external surface of said container, said method comprising:
providing said welding layer and said front layer; coupling said welding layer to said front layer through an intermediate layer of removable self-adhesive spread at at least one adhesion portion of mutually coupled surfaces of said welding layer and of said front layer; making an incision in at least one stretch of the thickness of the welding layer along at least one opening line adapted to define an access window of a closing element, wherein said incision divides the welding layer between a welding portion adapted to be welded to the container and an opening portion corresponding to said access window, with reference to an assembled configuration on the container, said incision being made so as to allow the detachment of said opening portion from said welding portion while said closing element is opened.
