ABSTRACT:
An infusion bag for particulated food products such as tea, coffee and the like, constructed of a tube of perforated thermoplastic film or other porous material having a central product containing portion and flattened end portions on each end thereof, the perforated thermoplastic film or other porous material having a multiplicity of minute holes or openings which are sufficiently small in size to prevent the migration of the particulated product therethrough and which are sufficiently large in size and number to permit adequate fluid flow therethrough. Joining together of the flattened end portions forms a flow-through or dual container type infusion bag and a handle for extending over the side of a cup or pot. The film is also substantially odorless and tasteless.
