VOLTAIC CELL AND METHOD OF MAKING SAME |
| 摘要 |
The zinc can (16) of a dry cell is closed by a pre-formed closure (25) which, when subjected to pressure from inside the can, flexes preferentially in a region (27) adjacent to the carbon rod (12) to vent the can and thereby limit the internal pressure. The closure is pre-stressed so that it automatically reseals the can as the internal pressure falls. |
