Abstract

Metoda za proizvodnju termoformiranih artikala, poput ambalaže za hranu (40) ili njenih dijelova, sa mehaničkim slabljenjem (33, 34) između susjednih funkcionalnih zona, koje su bar djelomično razdvojive jedna od druge na mjestu mehaničkog slabljenja (33, 34) prilikom uporabe od strane korisnika, u kalupu za termoformiranje sa gornjim kalupom (70) i donjim kalupom (80), koji su pokretni jedan u odnosu na drugi (smjer kretanja (100) kalupa), a metoda uključuje sljedeće korake: ulaganje plastičnog lista između gornjeg kalupa (70) i donjeg kalupa (80) i termoformiranje uvedenog plastičnog lista zatvaranjem gornjeg kalupa (70) i donjeg kalupa (80) u smjeru kretanja (100) kalupa, unošenje mehaničkog slabljenja (33, 34) u vremenskom razdoblju u kojem se materijal koji se oblikuje nalazi u kalupu za termoformiranje, naznačena time daje mehaničko slabljenje (33, 34) formirano u zonama artikla, koje su međusobno raspoređene u smjeru kretanja (100) kalupa i prostiru se okomito na njega, i/ili je mehaničko slabljenje (33, 34) formirano bar djelomično u najmanje jednoj ravnini protežući se u smjeru kretanja (100) kalupa pod uglom α (200) različitim od 90° u odnosu na pravac kretanja kalupa unutar termoformiranog artikla. Patent sadrži još 14 patentnih zahtjeva.
