A galvanic cell, especially a miniature galvanic cell, comprises a cupped container, a cover therefor, and a gasket, the cover having a depending flange, the gasket being compressed between the container and the flange of the cover such as to seal the cell and to electrically insulate the cover from the container, wherein the flange extends no further than half of the way into the container from the rim of the container and allows the gasket component to occupy less than 8 % of the internal volume of the cell, thereby allowing more room for active components.
L'invention concerne une cellule galvanique, en particulier une cellule galvanique miniature, comprenant un bac en cuvette sur lequel on place un couvercle avec un rebord dirigé vers le bas, et un joint d'étanchéité. Le joint d'étanchéité est comprimé dans le bac et le rebord du couvercle de façon à fermer la cellule et à isoler électriquement le couvercle du bac. Dans la présente cellule, le rebord ne s'étend pas au-delà de la moitié du bac en partant du haut de celui-ci, ce qui permet au joint d'étanchéité d'occuper moins de 8 % du volume intérieur libre de la cellule, laissant un espace plus grand aux composants actifs.
