ABSTRACT:
A filter bag for insusion products is provided having multiple successive container pockets or lobes, each for infusing a corresponding dose or unit quantity of product. The bag structure permits two usage layouts. The flat layout form is for packaging in lots for sale with said lobes superimposed or folded one over the other or side by side. The other layout form has the lobes opened out or distended following the pick up and pull of the corresponding tag (label) ending in the thread for handling the filter bag at the time of usage. The thread has a length equal to that of the bag as laid out for use with the pockets or lobes distended. The thread is fixed to the opposing ends of said bag by means of a piece of heat weldable material together with the non heat weldable paper tag (label) adjacent to one of said opposing ends. Additionally the thread is wrapped lengthwise externally to the bag when said pockets or lobes are in their position of usage and packaged in lots for sale with back-to-back folded lobes.
