<p>The filter for infusions, such as tea, or medicinal plants, is in two parts, one of which is a paper filter and the other a plastics support. The paper filter is a truncated cone shape at the base, and is disposable after use. The filter is fixed onto a base (1) by three valves which fit onto three studs. The base and its lid form the plastics support. The lid has a knob on, and clips onto the base via a small foot, and covers the valves with its three recesses.</p> |
