<p>The non-spill saucepan receptacle consists of a fixed mesh grid of one to two millimetres mesh width with support arms. The appliance is placed inside the pan and occupies almost the whole of the surface above the upper level of the liquid. The periphery of the grid is bent at ninety degrees upwards and over one centimetre width, to catch the bubbles produced from the boiling liquid. A tripod formed of two legs and a handle are fixed to the grill by a curved metal frame.</p> |
