PROBLEM TO BE SOLVED: To provide a refill container that is used for replenishing a repeatedly usable container with contents, the refill container using fewer components and enabling a user to easily replenish the container with the contents, without spilling them.SOLUTION: The repeatedly usable container 2 includes a discharging nozzle 221, and a peripheral wall 223 provided around the discharging nozzle via a passage 222 used for returning the contents of the container 2. The refill container 1 which seals the opening of a refill container body 11, made of paper as its main material, with a sealing film 12 is used to set the tensile elongation percentage of the sealing film at 10 to 700%. Thus, even when the leading end of the discharging nozzle comes into contact with the sealing film, the sealing film is prevented from being stretched and broken off. When the discharging nozzle enters sufficiently into the opening such that the sealing film exceeds the elongation limit thereof, the contents flows out from the refill container body with the sealing film broken off. |
