A package for containing a flowable infusible material comprising a closed bag made from a porous material. The bag has a first side, a second side that opposes the first side and two other sides. The package also has a drawstring that passes out of the interior of the package via a first exit point located adjacent one end of the first side and a second exit point located adjacent the other end of the first side. Means are provided to constrain the drawstring against adjacent the ends of the second side and at some intermediate point along each of said other sides (preferably near the midpoint). The arrangement being such that pulling the ends of the drawstring in substantially opposite directions causes the drawstring to move relative to the sides it engages and thus enable the package to collapse.
