Description of the Related Art Conventionally, a dry battery package in which a used dry battery and a new dry battery can be easily distinguished from each other by appearance is arranged in a state where a plurality of dry batteries are arranged in parallel and the whole is integrated and packaged with a heat-shrinkable film. It is known that a perforation is formed along the adjacent boundary of each dry battery, but in the packaging of this configuration, a positive electrode is cut when perforated when used. Since the protruding terminal and the negative electrode are covered with the heat-shrinkable film, the dry cell packaged with the heat-shrinkable film can be easily identified as a new dry cell. However, when cutting out the stacked and packed batteries one by one at a perforation, the heat shrinkable film packaging the plurality of batteries may be broken, and the individual batteries packaged may be separated, When that happens,
There is a disadvantage that it is difficult to distinguish used batteries from new batteries. Another disadvantage is that the process of stacking and packing the plurality of dry batteries on a heat-shrinkable film formed with perforations for cutting out such that the perforations are located at positions along adjacent boundaries of the individual dry batteries is complicated. is there.
