  • Patent number: 5951452
    Abstract: Two continuous travelling webs (1, 2) of porous material are provided for forming the eventual infusion packages. The lower web (2) is dosed with measured amounts (3) of infusible substance, such as tea, on its upper surface at spaced intervals by the dosing roller (4). Two continuous travelling strips (5, 6) of tag material such as card, are also provided to form the tags in the finished infusion packages. The strips are guided to travel parallel to and at the same speed as the webs (1, 2), respectively. A rotating string drum (8) forms a continuous length of string (7) into a succession of predetermined patterns. The upper web (1) and strip (5) of tag material are guided to be side by side, and then pass in face-to-face contact with heated roller (9) which melts the thermoplastics coating on the web and strip to render them adhesive.

  • Patent number: 5924354
    Abstract: An infusion container having an interior receiving a liquid to be infused and an infusible substance. Mounted to the container is a pivotal member which cooperates with a baffle means to define a region in the container which receives the infusible substance. Both the pivotal member and baffle means are adapted to permit passage of the infusing liquid, but not of the infusible substance. In use, the pivotal member can be pivoted through the interior by moving handle, to lift the infusible substance out of the infusing liquid to halt the infusion process at the desired time.
