PROBLEM TO BE SOLVED: To simply take out contents simply by piercing a piercing pouring device through a penetration seal-up film by a method wherein the film is heat- sealed with the property of being sealed-up maintained to one end of a tubular body having a thermoplastic resin layer at its inside and the other end of the tubular body is folded up and heat-sealed. SOLUTION: A tubular container applicable to a refill packaging bag for household liquid detergent is constructed of a tubular body 2 that is made up by overlapping opposite end edges of a laminated film and by heat-sealing the overlapped part with a side end heat-sealing part 3 and a spout 5 having an opening 6 at its center is attached to the edge on one end thereof. On this occasion, the opening 6 is sealed-up, being covered with a penetration seal-up film 7, and the film is heated-sealed with a spout heat-sealing part 8 and at the same time, the edge on the other end of the tubular body 2 is folded up and sealed up with a bottom heat-sealing part 4. Thereby, with a piercing tube 14 of a pump-equipped pouring device made to penetrate through the penetration seal-up film 7 and pierced into the inside of the tubular container, contents can be taken out in a small amount by operating the pump. |
