<p>When using containers for preparing hot or cold drinks or food, where the containers have at least one handle, a lid with a handle for opening the lid or a lid with a centrally arranged handle on a piston for the filtration of residuals from the drink, and particularly to a clock arranged in the piston knob, it can be paramount to know the temperature or the time lapsed since infusion or boiling took effect. This is achieved in that at least one thermoelectric element is used for electrically supplying an electrical clock and a display for either temperature and/or time, and that the display is arranged on the handle, the lid, or the handle of the lid, thereby indicating the size of the physical entity measured.</p> |
