METHOD FOR MANUFACTURING A CONTAINER OF PAPER MATERIAL FOR FOOD, FOR EXAMPLE LIQUIDS, IN PARTICULAR DRINKS, SUCH AS A PAPER GLASS FOR HOT DRINKS

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).
