Abstract

A method for manufacturing and filling a composite can (201), the method comprising: —forming a tubular body (203) by bending a body blank (16) and bringing two opposing edges of the body blank (16) together in an end-to-end join; —sealing the join by welding a sealing strip (214) over the join, thereby forming an intermediate can (403; 503); —sealing a top opening (211) by attaching a top sealing member (227) across the top opening (211); —applying a top rim (223) to the intermediate can (403; 503) by welding an inserted part of the top rim (223) to the inner surface of the tubular body (203); —turning the intermediate can (403; 503) upside-down and placing the intermediate can (403; 503) on a conveyor (2a) with the top rim (223) resting on the conveyor (2a); filling the intermediate can (403; 503) through the bottom opening (213); —sealing the bottom opening (213) of the tubular body (203) by attaching a bottom sealing member (215) across the bottom opening (213); —turning the intermediate can (403; 503) to bring the top rim (223) in an upward-facing position; —attaching a reclosable lid (221) at the top end of the tubular body (203). The intermediate can is kept in a protective gas atmosphere from said filling of said intermediate can until said bottom opening (213) of said tubular body (203) has been sealed. An assembly line (1) for manufacturing and filling of composite cans (201) is also disclosed.
