Patent

CA 2093820

The invention provides an infusion package comprising a closed bag containing an infusible substance for infusion in a liquid, the bag being formed from panels of porous material sealed together at their peripheral margins; and a pair of drawstrings, each of which extends into than interior of the bag through a seal between the panels at a first location 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. The invention also provides a method for the manufacture of the infusion packages.
