PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a liquid food container free from leakage by preventing a failure in sealing, a pin hole, a crack or the like from occurring in the vicinity of a lower flap on the bottom, and the container. SOLUTION: The "manufacturing apparatus for the liquid food container" 29 forms the liquid food container 34 consisting of a bottom 31 made of a thermoplastic material 30 and a sidewall 32 and a top 33 of a wrapper 2 of a paper base material 4, and the container is filled with a content liquid Q. The manufacturing method includes a feeding step 35 for continuously feeding out the wrapper 2 having a crease 20 formed, a cutting step 37 of laterally cutting the wrapper 2 into a sheet 36, a vertical sealing step 40 for vertically sealing 36b the sheet 36 into a short tube 39, a molding step 41 for molding an opening 39b of the short tube 39 of the thermoplastic material 30 to form the bottom 31, a filling step 44 of filling the content liquid Q from the opening 39b of the short tube 39, and a shaping step 43 for forming the sidewall 32 and the top 33 by folding and sealing the short tube 39 filled with the content liquid Q along the crease 20.
