Abstract: The present invention relates to a tube container which comprises: a tube which has a column shape; a shoulder which is welded to one end of the tube; and a cap which is combined with the shoulder; and a shoulder integrated one-touch cap which is formed by integrating the tube which has a column shape, the shoulder welded to one end of the tube, and the cap. A V-shaped groove or a U-shaped groove is formed in the outside or the inside of the shoulder and is partially thinner than the thickness of the shoulder in order to be easily deformed like a film so that the shoulder area can be folded like a film at a portion composing the shoulder combined with the column-shaped tube, thereby discharging remnants inside the shoulder to the maximum. In addition, an ejector pin is formed at an edge of the outer periphery at an area which is composed in the V-shaped or U-shaped groove and is bended in order to push remnants at an outlet for discharging. Thus, the ejector pin can be inserted into the outlet of the shoulder for pushing the remnant to the outlet to the maximum while the shoulder area bends to push the remnants to the outlet. Therefore, the tube container can prevent waste of resources at low costs by forming a V-shaped or a U-shaped groove capable of easily bending at a portion of a shoulder area of a tube and forming an ejector pin at an edge of the outer periphery of the shoulder at one end of the V-shaped and U-shaped groove in order to discharge remnants at an outlet, can avoid unsanitary situations and prevent accidents when cutting a film of the tube.
