A shaving foil for an electric shaving apparatus. The shaving foil includes a perforated region with a plurality of holes which are separated from each other by bars. The perforated region is divided at least into two zones, preferably a central zone, a first edge zone, and a second edge zone. The central zone is arranged between the first edge zone and the second edge zone. The holes in the central zone have (i) an average size which is smaller than the average size of the holes in the first edge zone and in the second edge zone, (ii) a floating mean value of the size of the openings in the central zone smaller than a floating mean value of the size of the openings in the first edge zone and the second edge zone, or both (i) and (ii).

Shaving foil for an electric shaving apparatus

The invention relates to a display device () for time-dependent processes, especially for displaying the change of a used toothbrush. The display device () consists of a storage chamber () containing a liquid and a porous indicator strip (), which is provided at one point with a dye () which dissolves in the liquid (), which after dissolving in the liquid (), colors the indicator strip () time-dependently over its length. The material of the indicator strip (), the liquid () and the dye () are matched to one another such that dye molecules () can adhere to the indicator strip () until the boundary surfaces () of the pores () are covered with dye molecules () while the remainder of the dye molecules () diffuse further in the liquid () and the adhesion process thus proceeds time-dependently. This produces a sharp color front.
