[0003] Examples of the object to be mounted include a bottomed cylindrical synthetic resin container molded into a cup shape by injection molding. As shown in FIG. 3, this container is formed in a tapered shape in which the body 2 'of the container main body 1' is gradually reduced in diameter toward the bottom 3 ', so that the cylindrical label 5 covered on the container main body 1' is formed. When the 'is thermally shrunk, the tubular label 5' tends to be displaced downward from the container body 1 'due to the difference in the shrinkage, and tends to come off after being mounted. Therefore, conventionally, a heat-sensitive adhesive 7 ′ is applied to the inner surface of the upper open end of the tubular label 5 ′ by gravure printing or the like, and when the tubular label 5 ′ is thermally contracted, the heat-sensitive adhesive is used. 7 'prevents the cylindrical label 5' from being displaced.

Here, as the heat-sensitive adhesive, a hot-melt type adhesive or a delayed tack type adhesive is used. These adhesives do not have adhesive properties at room temperature, but exhibit adhesive properties when heated. However, depending on the storage state, the adhesive property of the heat-sensitive adhesive may occur. In this case, the inner surfaces of the flatly folded tubular labels are adhered to each other to make opening work difficult, so-called “blocking”. Can occur. In particular, when the portions to which the heat-sensitive adhesive is applied are in contact with each other, the occurrence of "blocking" becomes remarkable.

FIG. 4 shows a conventional tubular label 5 'which solves such a problem. The tubular label 5 ′ is formed by joining both ends of a rectangular heat-shrinkable film (the joining form is not shown) and inside the upper open end of a tubular label base material 6 ′. When the material 6 'is folded flat, the heat-sensitive adhesive 7a' on one surface and the heat-sensitive adhesive 7b 'on the other surface do not face each other, and the heat-sensitive adhesives 7,. It is applied at regular intervals in the circling direction.

However, in the conventional cylindrical label 5 ', as shown in FIG. 3, the distance between the heat-sensitive adhesives 7',... Is large (one more between the heat-sensitive adhesives 7 ', 7'). There is a space where the heat-sensitive adhesive can be applied), and the application length of the heat-sensitive adhesive 7 ',... On the entire circumference of the label base material 6' is small, so that the sticking strength is weak and the cylindrical label 5 ' If a forcible force is applied by dragging downward or twisting in the lateral direction, the tubular label 5 ′ may easily come off the container body 1 ′.

As described above, in the tubular label according to the present invention, the heat-sensitive adhesive is applied in the circumferential direction at the open end of the label substrate, and the label substrate is folded flat. In order that the heat-sensitive adhesive on one side and the heat-sensitive adhesive on the other side do not oppose each other, any one of the heat-sensitive adhesives is applied displaced in the cylinder axis direction, so that "blocking" Not only can be suitably prevented, but also a suitable adhesive force can be exerted on the container body, so that "sink" of the edge of the label base material can be suitably prevented.
