Abstract: An infusible package includes a closed bag, containing an infusible substance for infusion in a liquid. The bag is formed from panels of porous material sealed at their peripheral margins; and at least one string. Each string extends through a seal between the panels, enters the interior of the bag at a point on the peripheral margins and extends across the interior of the bag to an anchoring point at or adjacent the peripheral margins. The length of that portion of each string which extends across the interior of the bag between the point on the peripheral margins and the anchoring point is greater than the distance between that point and the anchoring point. With this arrangement, pulling the string initially causes withdrawal from the bag interior of slack string length disposed therein.

Abstract: The invention provides an infusion package comprising a closed bag (1) containing an infusible substance for infusion in a liquid, the bag being formed from panels (2,3) of porous material sealed together at their peripheral margins (4); and a pair of drawstrings (11, 12), each of which extends into the interior of the bag through a seal between the panels at a first location (13,14) on the peripheral margins, and extends across the interior of the bag to an anchoring point at a generally opposed location on the peripheral margins without any intermediate interengagement with the said panels of the bag; and wherein each drawstring is anchored by being held between two sealed together portions of the panels, the arrangement being such that pulling the drawstrings in generally opposite directions causes the bag to collapse, thereby to express liquid absorbed by the infusible substance during infusion. The infusion package is preferably a tea bag or coffee bag.
