<p>PCT No. PCT/GB92/00265 Sec. 371 Date Oct. 12, 1993 Sec. 102(e) Date Oct. 12, 1993 PCT Filed Feb. 14, 1992 PCT Pub. No. WO92/14649 PCT Pub. Date Sep. 3, 1992.A two-ply tagged infusion package comprises a tag formed of a length of string (3) and a tab (5). The tag is located as one of a continuous string on a first web (1) in a convoluted form, the first web then being joined to a second web by heat sealing rollers (8) to form a travelling two-ply web having infusion containing pockets (11), each having a tag located thereon within the periphery of the final package. A loop of string (4) of each tag is anchored in the heat seal formed around the pockets (11). The individual packages are then cut from the travelling two-ply web by, for example, co-rotating cutting rollers defining the shape of the package. The act of cutting the packages from the web also serves to cut the continuous string of tags into individual tags (3).</p> |
