The plug 6 is placed in the upper opening of the label 1 and pushed into the inside of the label 1 using a plug 6 having a smaller diameter than the cylindrical label 1. In addition, at this time, the resin sheet 5 is pressed against the upper part of the label 1, and the label 1 is
If there is a possibility that the resin sheet 5 may be pressed against the label 1, the upper positions A and A of the label 1 on the resin sheet 5 may be fixed by adsorption with a holder (not shown). At this time, it is convenient if the plug 6 is heated because the resin sheet 5 will not be cooled down.

On the other hand, since the label 1 follows the inner surface of the mold 2, the resin sheet 5 molded inside the label 1 is also molded into a predetermined appropriate container shape. Further, the adhesive layer 4 on the inner surface of the label 1 is heated and becomes firmly and integrally bonded to the outer surface of the resin sheet 5.
尚、上記実施例では、成形型２内にラベル１を挿入した

の低減化が図れるという格別な効果を有するに至った。(Effects of the Invention) As described above, the present invention provides a cylindrical label that can be heated and stretched, and when expanding a resin sheet placed inside the label in the radial direction, the label is heated. In addition, the label expands in the radial direction along with the resin sheet and is molded into a shape that follows the inner surface of the mold, so even if the label is formed in a shape that does not match the mold, it will match the shape of the mold appropriately. This allows it to be molded into any shape. As a result, there is no need to preform the label inserted into the mold into a shape that conforms to the inner surface of the mold as in conventional methods, making the label molding process much easier than conventional molding operations. This has resulted in the exceptional effect of simplifying manufacturing operations and reducing manufacturing costs.

至った。In addition, in the present invention, since the container is formed by expanding the resin sheet into a shape along the inner surface of the mold, unlike the conventional label, which is inappropriately preformed, the resin sheet is expanded in the radial direction. The present invention also has the advantageous effect that the resin sheet can be molded into a container with an appropriate shape corresponding to the mold, without the risk of being unduly restricted.
