Abstract

Przedmiotem zgłoszenia jest sposób trzymania i uszczelniania preformy z PET w procesie kształtowania korpusu puszki metodą rozdmuchu korzystnie dwustopniowego z jednoczesnym rozciąganiem, przy czym korpus preformy (6) po przeciwnej stronie względem dna preformy ma szyjkę zakończoną pierścieniowym kołnierzem (1) korzystnie o grubości od 0,3 do 0,5 mm, wygiętym na zewnątrz korpusu, przy czym korpus preformy (6) umieszcza się w gnieździe (3) formy rozdmuchowej (2) odzwierciedlającym kształt korpusu puszki, a pierścieniowy kołnierz (1) umieszcza się na zewnątrz formy rozdmuchowej charakteryzuje się tym, że pierścieniowy kołnierz (1) dociska się w kierunku do zewnętrznej powierzchni formy rozdmuchowej (2) przez część (5) doprowadzającą sprężone powietrze do korpusu preformy (6). Pierścieniowy kołnierz (1) dolną powierzchnią opiera się o zewnętrzną czołową powierzchnię formy rozdmuchowej (2), albo o element pośredni, który usytuowany jest na zewnętrznej powierzchni formy rozdmuchowej (2) wokół gniazda (3).The subject of the application is a method of holding and sealing a PET preform in the process of shaping a can body by means of a blow molding method, preferably two-stage with simultaneous stretching, the body of the preform (6) on the opposite side to the bottom of the preform having a neck ending with an annular collar (1) preferably with a thickness of 0, 3 to 0.5 mm, bent outwards from the body, the preform body (6) being placed in the seat (3) of the blow molding tool (2) reflecting the shape of the can body, and the annular collar (1) being placed outside the blow molding tool characterized by in that the annular collar (1) is pressed towards the outer surface of the blow mold (2) by the compressed air supply part (5) to the preform body (6). The annular collar (1) rests with its lower surface against the outer face of the blow molding tool (2) or against an intermediate element which is located on the outer surface of the blow mold (2) around the seat (3).
