Abstract

An infusion packet comprises a pair of sealed compartments (12a, 12b) containing infusion material and joined together at opposite ends of the packet. A drawstring (14) attached intermediate its length to a connecting region (8) between the two compartments at one said end has pull portions extending between the compartments from said attachment and held movably at the opposite end of the packet, whereby said pull portions can be drawn apart to contract the packet. To produce the packet the compartments are initially formed end to end, joined by the connecting region. An intermediate portion (16) of the drawstring is attached to the connecting region before the compartments are doubled over to bring their opposite ends together with drawstring pull portions between them. Said opposite ends are then secured together in a manner permitting movement of the drawstring pull portions between them to contract the packet.
