Description of the Related Art Conventionally, when a synthetic resin container is molded, a label to be attached at the same time as molding in a mold is to adhere to a label base made of a synthetic resin film that has been printed or the like. The one provided with the adhesive layer has been used. As this adhesive layer, an adhesive such as hot melt is applied to the entire surface of one side of the label substrate, or a synthetic resin film having one side of the label substrate having thermal adhesiveness to the container. There are things that consist of.

が生じていた。However, such a label having an adhesive layer provided on the entire surface on one side, when being adhered to the container in the mold,
When air is mixed between the container and the label, the adhesive layer cannot be released because the adhesive layer is provided on the entire surface of the label substrate, and air bubbles are generated in the label adhered to the molded container. Blisters and the like occur, which causes a problem of impairing aesthetics.
【０００４】上記のような問題を解決するために、例え

形成されている。Such a small hole 23 allows a small amount of air to be trapped between the label body and the container when the label is adhered to the container when the container is molded. The small hole 23 is usually formed to prevent swelling and wrinkling of the label while allowing it to escape to the outside.
Since the needle 24 is pierced by piercing the tip of the needle 24 from the outer surface 21a side, the opening area of the outer surface 21a of the label body 21 is
23a is formed in an inverted conical shape larger than the opening area 23b of the inner surface 21b.

のではなかった。However, as described above, the opening area 23b of the inner surface 21b of the label body 21, which is the entrance of the air, has the outer surface 21b.
Since it is formed to be smaller than the opening area 23a of a, it is difficult for air to enter the small holes 23, and especially in a portion where the curvature radius of the curved surface of the container is small, a portion where the curvature radius changes, etc. Cannot effectively escape the air from the small holes 23 and cannot reliably prevent the label from bulging.
【０００７】また、このようなラベルは容器の外周に接
