Abstract
A tube container has an outer tube formed with an extruding mouth at one end and two inner tubes each formed with an extruding mouth at one end. The inner tubes are inserted into the outer tube, and the extruding mouths of the two inner tubes are secured to the extruding mouth of the outer tube, respectively, while the other ends of the two inner tubes and the other end of the outer tube are pressed and welded together to form a hermetically sealed portion. The outer tube has a transverse cross section taking the form of an ellipse or a closed running track shape, namely a shape combining two semicircles with two straight lines. The inner tubes are arranged in the outer tube in the direction of major axis of the transverse cross section of the outer tube. The other ends of the two inner tubes and the other end of the outer tube are pressed in the minor axis of the transverse cross section and welded together, wherein the respective hermetically sealed portions of the two inner tubes have a length more than half of the hermetically sealed portion of the outer tube, and a part of one inner tube and a part of the other inner tube lie one upon the other.
