(FR) PRODUIT EN CARTON REVÊTU ET FAÇONNÉ ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN)
A coated and shaped board product (101) comprises a shaped element (102) made of board, for example paperboard or metal foil. The shaped element is seamless and has folds (103) to form a three-dimensional shape of the shaped element. The coated and shaped board product further comprises a coating membrane (104) attached to a surface of the shaped element. The coating membrane is arranged to cover the folds of the shaped element so that the coating membrane is free from folds and wrinkles. As the coating membrane is free from folds and wrinkles, a hermetic room can be implemented by attaching a cover element to edge areas of the coating membrane.
(FR)
Produit en carton revêtu et façonné (101) comprenant un élément façonné (102) composé de carton, par exemple du carton blanchi ou une feuille métallique. L'élément façonné est sans soudure et présente des plis (103) qui lui confèrent une forme tridimensionnelle. Le produit en carton revêtu et façonné comprend en outre une membrane de revêtement (104) fixée à une surface de l'élément façonné. La membrane de revêtement est conçue pour recouvrir les plis de l'élément façonné de sorte que la membrane de revêtement soit dépourvue de plis et de rides. La membrane de revêtement étant dépourvue de plis et de rides, une pièce hermétique peut être mise en œuvre par fixation d'un élément de couverture sur des zones de bord de la membrane de revêtement.
