Thermally insulatable vessel

This technology is available under CERN Easy Access IP


The Thermally insulatable vessel is a simple container system for hot substances, incorporating a temperature display within the vessel’s cap or lid. The key element in this technology is an integrated infra-red thermometer developed with Micro-Electro-Mechanical systems on a common silicon substrate through micro fabrication technology. The temperature display is attached to the upper part of the cap and the electronics are fitted inside the cap. A remarkable detail is that an (IR) window is made of a transparent plastic foil created by thinning the bottom part of the cap from inside.

Area of expertise



  • Thermal bottle applications in outdoor/leisure/adventure/children and babies markets
  • Food storage and services industry applications in cafeterias, restaurants and catering markets
  • Process industry


  • Easily integrated, compact system
  • Continuous measurement and display of vessel temperature
  • Contactless IR technology
  • Simple to use


  • Error of measurement at low temperatures (less than ambient temperature - 20 ºC)
  • Disturbance in the form of infrared radiation influenced by the cap
  • High power consumption of the sensor system
