Description of the Related Art Conventionally, as an outer label for a dry battery, a label having a heat-shrinkable label having a metal vapor-deposited layer of aluminum and having a pressure-sensitive adhesive layer on one surface is attached to a release paper. (For example, JP-A-59-123161). When using the label body, peel off the label body from the release paper, wrap it around the dry cell body, and heat and shrink the outer label end that protrudes to the head and bottom of the dry cell body to remove the head and bottom of the dry cell body. The periphery can be cosmetically coated.

４４号公報）。It is essential that the label having this structure has a release paper laminated on the back surface, and it must be wound around the dry battery main body while peeling off the release paper before the winding operation. Therefore, the material structure becomes expensive, and the peeling work requires a complicated method. Therefore, labels using so-called heat-sensitive adhesives such as hot-melt adhesives that do not require release paper have come to be used (for example, Japanese Patent Laid-Open No. 2-1956).
No. 44).

ルの外観上の不具合を生じるという問題があった。However, in the above-mentioned outer label using the conventional heat-sensitive adhesive, the outer label is applied to the surface of the battery case made of iron or nickel-plated steel used in, for example, alkaline batteries. When a label is attached, a local battery is formed between the surface of these cases and the metal deposition layer due to moisture in the air, especially during storage of the battery under high temperature and high humidity, and the metal layer elutes to give a metallic luster. There is a problem in that the external label loses its appearance and has a defect in appearance.

An object of the present invention is to provide a label-clad battery having a good appearance.

In addition, a heat-resistant electric insulating layer is provided between the adhesive layer and the metal layer. Further, the outer label is wound around the body of the cylindrical battery so that the upper and lower ends thereof protrude to the upper and lower ends of the battery body, and the protruding upper and lower ends of the outer label are heat-shrinked so that the battery A label-clad battery formed by closely contacting the body and the upper and lower edges of the body,
The heat-resistant electrical insulating layer, at least of the outer label,
It is characterized by having a corner portion covering a portion extending from the battery body portion to the upper and lower end peripheral portions of the body portion.

沢を失い外観上の不具合を生じることになる。With this configuration, it is possible to prevent the appearance defect of the outer label that the metal layer of the outer label is eluted and loses the metallic luster, especially during storage of the battery under high temperature and high humidity. This effect is presumed to be due to the following reasons. That is, the heat-shrinkable label using the heat-sensitive adhesive is wrapped around the battery body while melting the heat-sensitive adhesive layer formed on the back side by heat, solidified by cooling, and adhered in the state wrapped around the battery body. . Upon solidification by this cooling, pinholes and cracks are generated in the heat-sensitive adhesive layer. For this reason, the metal layer of the label, for example, the vapor-deposited aluminum layer and the battery case, for example, the nickel-plated steel sheet that also serves as the positive electrode terminal, come into contact with each other. Then, particularly under high temperature and high humidity, moisture in the air is absorbed to form a local battery between the battery case and the metal layer of the label, and aluminum is eluted. Due to this phenomenon, the exterior label partially loses the metallic luster and causes a defect in appearance.

ある。This phenomenon is remarkable at the corners connected to the upper and lower ends of the outer label protruding from the battery body of the outer label, which has a large degree of heat shrinkage of the outer label and is easily pressed by the heat shrinkage. This is because the heat-sensitive adhesive layer shrinks while melting, so that the adhesive layer at the corner is pushed away, and the metal layer of the label and the battery case are in direct contact with each other at this part, and a local battery is easily formed. It is thought to be because. Therefore, by providing a heat-resistant electric insulating layer between the heat-sensitive adhesive layer and the metal layer of the outer label of the present invention, formation of the above-mentioned local battery is prevented, and elution of the metal layer can be prevented. Inferred. The heat resistant electrically insulating layer is a layer of thermoplastic synthetic resin or the like having a higher softening point than the heat sensitive adhesive layer.
