PROBLEM TO BE SOLVED: To reliably impart self-standing property to a tube by making the tube penetrate a non-stretched layer in a state of stretching and deforming the non-stretched layer to be sufficiently large, and effectively prevent a liquid packaged object from leaking from the periphery of the tube unexpectedly and outside air from intruding into a package by adhering the non-stretched layer to the tube.SOLUTION: A tube device takes out a packaged object in a bag by inserting a suction tube from outside into a package which is formed by filling a liquid packaged object in a packaging bag made of a laminate film that comprises a base film layer, a remover coating layer provided on a rear face side of the base film layer, and a non-stretched layer laminated through the remover coating layer. An insertion guide scratch is provided on the base film layer at a position corresponding to the remover coating layer. An insertion tip of the suction tube is formed of a flat surface or a substantially flat surface in which chamfering is applied to a shoulder part of an outer peripheral edge, and an insertion rear end part of the suction tube has a flange.SELECTED DRAWING: Figure 5 |
