<p>An infusion package (1) comprising a chamber (5) for containing an infusible substance, said chamber (5) being formed from three or more corresponding pieces (10) of porous material that are joined at their respective peripheral margins such that when the package (1) is immersed in a liquid the chamber (5) swells to approximate a spherical shape. The chamber (5) is preferably formed from three or four pieces (10) of porous material that are substantially round or otherwise elliptical in shape. A method and an apparatus for making such infusion packages are also described. <IMAGE> <IMAGE></p> |
