[Problems to be solved by the invention]
Generally, the expiration date is written on foodstuffs. The expiration date is specified for medicines and the like. Dry batteries whose voltage gradually decreases due to self-discharge are no exception, and the recommended usage period is indicated by engraving or printing. However, the conventional recommended expiration date is displayed small in an inconspicuous part of the battery surface and will not be seen unless it is carefully searched. In particular, in the case of battery packs, since the batteries are packaged with the face of the batteries aligned in front, the previous display is likely to be hidden on the adjacent side of the batteries. It is difficult to know. When the shrink wrap or blister pack is opened, the recommended expiration date can be known, but even if the product is returned because the expiration date is approaching, it cannot be sold again as a battery pack.
[0005]
An object of the present invention is to provide a dry battery that can clearly display the recommended expiration date even when the dry battery is sold as a unit as well as when it is sold in a packed state, thereby providing appropriate product information to consumers. And a battery pack.

The area occupied by the term display 7 on the face 6 is set to 1 to 40% of the area of the face 6 so that the main display such as the maker name 4 can be markedly noticeable while the term display 7 is easily visible. This is for displaying. If the area occupied by the expiration date display 7 is 1% or less, it is difficult to see unless the expiration date display is carefully searched, similarly to the conventional recommended expiration date. On the other hand, if the area occupied by the term display 7 exceeds 40%, the display area of the manufacturer name 4 becomes extremely small, and the appeal to consumers cannot be sufficiently exhibited.
[0012]
When the expiration date display 7 is provided at one of the upper and lower ends of the face surface 6 of the dry battery 1, there is no need to change a conventional print display, for example, a main print display such as the manufacturer name 4, and the expiration date display 7 The recommended expiration date can be clearly displayed while inheriting past product images.
[0013]
If either one of the front surface of the battery pack 10 and the face surface 6 of the dry battery 1 constituting the battery pack 10 is provided with the expiration date indication 7 indicating the recommended expiration date, the packaging material 8 can be opened. The period display 7 can be clearly confirmed without any change. That is, it is possible to clearly display the time limit display 7 at a position where it is easy to see, and to provide consumers with appropriate product information.
[0014]
If the expiration date display 7 indicating the recommended use expiration date is provided on the face surface 6 of the dry battery 1 constituting the battery pack 10, the expiration date display 7 can be seen through the transparent packaging material 8. The period display 7 can be confirmed without opening the box 8. Since the outer surface of the time limit display 7 is covered with the packaging material 8, the time limit display 7 is not easily tampered with.
[0015]
If the expiration date display 7 indicating the recommended expiration date of the dry battery 1 is provided on the surface of the packaging material 8 of the battery pack 10, the expiration date display 7 can be displayed large regardless of the size of the dry battery 1. When the expiration date display 7 is also provided on the dry battery 1 side, even when the packaging material 8 is opened and the dry battery 1 is separated, the recommended use expiration date can be confirmed. Since the packaging material 8 can be formed of an opaque sheet, a colored printed sheet, or the like, the degree of freedom in designing the packaging material 8 is improved.
