Claim:
A packaging method comprising the steps of: setting a bag in which contents are packed, in an openable outer case provided with an opening flap, wherein the contents are adhesive and a frictional force is created between the contents and the bag; turning back part of the bag at fold portions so that the part of the bag having an open end is turned inside out around the opening flap, such that the inner surface of the bag at the out-turned portion of the bag faces the environment surrounding the outer case; fixing at least part of the out-turned part as a fixing part the outer case by inserting the fixing part in at least one cutout in at least one side surface of the outer case; supporting the outer case with at least one arm; bringing inner surfaces of the bag at the fold portions into contact with each other, forming a contact portion, wherein the adhesive contents seal themselves against the fold portions of the bag by their own weight when the outer case is supported with the at least one arm; and placing the contact portion of the bag in correspondence with an openable part of the flap of the outer case; wherein the bag is configured so that the adhesive contents push apart the opening flap of the bag and empty themselves by their own weight once the at least one arm is removed.
