摘要:
A process for realizing a container from a foldable sheet comprises stages of at least partially inserting a closure element made of paper material (extensible paper) provided with a base wall and a lateral wall internally of a housing chamber of the container. The lateral wall of the closure element is inserted and located at a portion of the wall of the container. Also comprised is a stage of contemporary deformation of the lateral wall of the closure element and the portion of wall of the container in order to realize corresponding grooves on the parts, destined to define coupling and decoupling surfaces by rotation between the closure element and the container. The use of extensible paper advantageously enables easy realization of the coupling grooves by rotation.

摘要:
A method has been conceived for the manufacture of containers in paper material for foodstuffs such as drinks, in particular hot drinks, comprising a bottom wall (2) and a lateral wall (3) arising from the bottom wall (2) and forming in cooperation with the latter a cavity (4) for containing the product; means (5) are also provided to allow the hand of a user to be thermally insulated with respect to the product contained in the cavity (4). The method comprises a step of turning the lateral wall (3) back outwards and downwards so that the material constituting the upper portion of the lateral wall of the preliminary container comes step by step to constitute the external strip (6).

The invention relates to a process for realising a re-closable container made of extensible paper, which comprises at least partly inserting a closing element (5) made of paper material (extensible paper) provided with a base wall (6) and a lateral wall (7), internally of a housing compartment (4) of the container. The lateral wall (7) of the closing element (5) is inserted and located at a portion of lateral wall of the container (1). A sealing layer (204) is coupled to the container in a position underlying the closing element (5). Also comprised is a contemporary deforming step of the lateral wall (7), the sealing layer (204) and the portion of wall of the container (1), such as to realise coupling/decoupling surfaces between the closing element (5) and the container (1).
摘要:
A method for forming three-dimensional containers of extensible paper material, characterised by: - forming a tubular element (2) from extensible paper material, - associating the tubular element obtained in this manner with a mould (4) negatively reproducing at least the side wall of the container to be obtained, - causing the tubular element (2) to adhere to the mould walls by utilizing the extensibility characteristics of the paper material, - closing said tubular element at at least one end.
