The present invention relates to a labeled tube container, and more particularly to a tube container comprising a tubular body made of a synthetic resin and a label of a synthetic resin-made label attached to the main body of the tube body. .

In the past, a synthetic resin in which a content such as a creamy or gel-like cosmetic, a food, a toothpaste, an adhesive, or the like is filled and stored as a content and extruded from a discharge port of the outlet portion is used. The tube container is replaced by a tube container made of aluminum. In the tube container made of a synthetic resin, for example, a synthetic resin such as a polyolefin such as polyethylene or polypropylene is used to form the tube main body, whereby the main body portion has flexibility and flexibility.

In the tube container made of synthetic resin, the tube main body is preferably supplied to the filling device in a state where one end portion of the cylindrical main body portion is provided with the spout portion, and is filled from the opening portion of the other end portion of the main body portion. After the contents, the other end portion is closed by forming an end seal portion using an end sealing device (for example, refer to Patent Document 1).

In the end sealing step using the end sealing device described in Patent Document 1, the inclusion is fixed to the section The guide vanes of the two flat plates of the shape of the word are guided so that the other end portion of the main body portion of the pipe body protrudes from the guide vane in a state of being collapsed to a flat state, and then the other end portion is sandwiched by a pair of jaws One end is temporarily fixed. Thereafter, after the other end portion temporarily fixed in a state of being collapsed to a flat state is thermally fused by the heater device, it is preferable that the sealing rod is sandwiched by one of the concave and convex patterns appropriately formed on the nip surface. The pressure collapses, thereby forming an end seal. Further, the resin sheet which has been subjected to the collapse of the self-sealing rod as a burr or the like is removed by trimming (cutting), thereby completing the final processing of the end seal portion.
