Abstract:

To provide a dry cell package wrapped with a seal for a cell, composed by sealing one-side electrode sides of a plurality of dry cells connected in parallel with one another with the seal for a dry cell to prevent deforming of the shaped remaining dry cells when a desired number of the dry cells are removed, and allowing the determination of whether the individual removed dry cells are used or not to be properly carried out.

Three surfaces comprising a surface for continuously covering the respective positive electrode terminals of a plurality of the dry cells 11a, 11b, 11c and 11d and areas among the respective positive electrode terminals, and both facing side surfaces thereof are covered with the sealing seal 10 for a cell to rectify the shape thereof and seal them, and wrapped with a shrink film. For the sealing seal 10 for a cell, separation lines 14a, 14b and 14c are formed on boundaries between the dry cells, and tab pieces 16a, 16b and 16c for imparting tensile force for cutting it along the separation lines are formed by cutting out at least one side edge on the extension of each separation line.
