PROBLEM TO BE SOLVED: To provide a tube container wherein rigidity at a head is high even though a total resin amount is reduced, it is light and easy to fit a hinged cap and contents are difficult to leak by joining an entirely flat and thin closure member comprising the head and the hinged cap with an end of a cylindrical barrel. SOLUTION: The tube container comprises a closure member 30 made of a polyolefin-based resin having a head 10 and a hinged cap 20 which are rotatably connected with each other via a hinge 33 wherein the member 30 is joined by a joint 8 at a peripheral end of the head 10 with an end of a cylindrical barrel 1 by hot bonding. An adhesive polyolefin-based resin layer is provided on a joint face of the barrel 1, or a resin layer of the same material as that of the closure member 30 is provided, while reinforcing ribs 6, 7 are provided inside the head 10 or only a center part is made to be thick, whereby a peripheral part is made to be thin and easy to flex. In addition, a fitting part of the head 10 with the hinged cap 20 is provided in addition to fitting between a pour-out port and a plug. |
