Abstract
A double compartment infusion packet has a drawstring (4) running through both compartments. The compartments are doubled over are joined together at opposite ends. The drawstring has an intermediate portion (6) retained at one end between the compartments and further portions (8) extending through the compartments to the other end where the ends of the drawstring are secured to a tag card (40). The tag card overlaps the sealing of the compartments at the other end and is secured there to the packet material. A line of weakening (42) allows the tag card to be detached to draw out the further portions of the drawstring to contract the packet and squeeze out excess moisture after infusion.
