<p>Provided is an apparatus for manufacturing a packaged body wherein the required amount of inert gas can be limited and the interior of an outer wrapping material can be filled efficiently with inert gas. The apparatus for manufacturing a packaged body comprises an edge front-seal member (41) for partially sealing a region of an open edge (F1B) so as to form an edge non-seal portion, an edge rear-seal member (42) for also sealing the edge non-seal portion, a width-direction front-seal member (51) for partial sealing so as to form a width-direction non-seal portion, a width-direction rear-seal member (52) for also sealing the width-direction non-seal portion, and a gas injection tube (60) which enters between the films of a strip laminate film (F1) and injects inert gas, wherein the gas injection tube (60) is arranged to pass through the range of the width-direction non-seal portion, the distal end thereof reaching a position between the width-direction front-seal member (51) and the width-direction rear-seal member (52) in the feeding direction, and a plurality of air outlets (61) are formed within a range where at least the width-direction front-seal member (51) and the width-direction rear-seal member (52) are located.</p> |
