Title:
METHOD FOR MANUFACTURING A PAPER CONTAINER
Document Type and Number:
WIPO Patent Application WO/2010/116223
Kind Code:
A3
Abstract:
A process for realising a container from a foldable sheet comprises stages of at least partially insering a closure element (5) made of paper material (extensible paper) provided with a base wall (6) and a lateral wall (7) internally of a housing chamber (4) of the container. The lateral wall (7) of the closure element (5) is inserted and located at a portion (3a) of the wall (3) of the container (1). Also comprised is a stage of contemporary deformation of the lateral wall (7) of the closure element (5) and the portion (3a) of wall of the container (1) in order to realise corresponding grooves (9, 10) on the parts, destined to define coupling and decoupling surfaces by rotation between the closure element (5) and the container (1). The use of extensible paper advantageously enables easy realisation of the coupling grooves by rotation.
