Title (EN) METHOD OF THERMOFORMING A CONTAINER OF CORRUGATED MATERIAL AND CONTAINER CONTAINER FORMED THEREBY
(FR) PROCEDE DE THERMOFORMAGE D'UN RECIPIENT DE MATERIAU ONDULE ET RECIPIENT AINSI OBTENU
Abstract:
(EN) The present invention is a method for forming a corrugated container (20) having a double wall construction. A blank (30) is formed of a pair of corrugated layers (32, 46) sandwiched between and adhered to adjacent flat layers (34, 36, 48) and having a sufficient moisture content to enable the blank (30) to be formed. The blank (30) can include printed indicia (56), thermoresistant coatings (54), release coatings (54), and other coatings applied to the blank (30) to enhance the utility of the container (20) formed from the blank (30). The blank (30) is then inserted into a thermoforming machine (58) in which a pair of heated dies (80, 82) compress the blank (30) into the desired container shape (20).
(FR) L'invention porte sur un procédé de formation d'un récipient (20) à paroi double de matériau ondulé. A cet effet on utilise une ébauche constituée d'une paire de couches ondulées comprises entre deux couches planes (34, 36, 48) et y adhérant, et dont la teneur en humidité est suffisante pour permettre le formage de l'ébauche (30). L'ébauche (30) peut comporter des signes imprimés (56), des revêtements thermorésistants (54), des revêtements anti-adhérence, et d'autres revêtements, afin d'accroître l'utilité du récipient (20). On place ensuite l'ébauche dans une thermoformeuse (58) à paire de matrices chauffantes qui la compriment pour lui donner la forme voulue.
