PROBLEM TO BE SOLVED: To provide a cartridge type container in which a weight of its material can be reduced, a classification between plastics and paper can be easily carried out, and ink in a tray can be fully consumed as the ink in a bag is sucked up through a pouring inlet. SOLUTION: The container relates to a cartridge type container comprised of a tray container lower segment having such a shape as one in which a parallelepiped member having a plastic film layer closely adhered to the inner surface of a paper tray having a flange segment assembled with a blank of paper major material is divided into two segments at its orthogonal planes, and a tray container upper segment. Both the lower segment and the upper segment are connected to each other by the flange. The side surface of the tray container lower segment is provided with a pouring inlet. The plastic film layer at the tray container upper segment except the flange is closely adhered in such a way that it can be peeled off. The paper tray of the tray container lower segment and the paper tray of the tray container upper segment are assembled with two blanks, i.e., one blank having as its major material the flange and the other blank having as its major material either the upper surface or the bottom surface. Both flanges are of flat surfaces having no step at all.
