  • Patent number: 7401450
    Abstract: This invention concerns an infusion bag, especially for tea, which has a top part with folded down corners and a middle part folded over it, to which a string with two free ends is attached that goes from one side of the top part through a hole in the folded down parts forming a loop on the other side of the top part and comes back, whereby the two free ends are drawn up through the loop laid over the top edge of the infusion bag and pulled to form a knot. The solution in the invention is characterized by the fact that two holes are made in the top part at a lateral distance next to one another, on the left and right of the longitudinal axis of the bag; each hole goes through a folded down corner and the middle of the top part; by the fact that the string forms a loop and one end goes through one hole and the other end through the second hole; by the fact that the loop is laid over the top edge of the infusion bag, and both ends of the string go up through the loop to form a double knot.

  • Patent number: 6733804
    Abstract: An infusion bag for preparing tea including a suspension unit having a grasping area and at least two chambers for containing an amount of a substance, the chambers each having a top side and being connected to one another at respective top sides to form a common edge. The chambers are connected to the suspension unit at the common edge and are turned away from the grasping area. The suspension unit is preferably longer than the chambers.

  • Patent number: 6725628
    Abstract: This invention relates to a process for the continuous production of beverage filter bags, especially tea bags with a hanging strip made from a carrier sheet material and with at least one pocket which consists of a filter material and is closed on all sides, contains at least one portion of a beverage substance, and is connected to the hanging strip; whereby individual beverage-substance portions are deposited in a row on a continuous web of filter paper, a sleeve is formed, at least one string of consecutive, contiguous pockets, each containing one portion of the substance, is produced by individually sealing them off with a transverse seam, said transverse seam including both the trailing seam of one pocket and the leading seam of the following pocket, with perforations between the two seams along which neighboring pockets can be separated in the course of the process; the individual pocket is separated from the string of pockets; the pocket separated from the string of pockets is connected to a hanging-st

  • Patent number: 6675553
    Abstract: This invention concerns a method and a device for stacking and packing groups of infusion bags, especially for making tea, whereby in continuous production infusion bags arranged one after another in a series in a strand are separated, their speed of movement is reduced and they are put in a position suitable for making a stack, whereby the infusion bags are arranged one after another in such a way that they at least partly overlap in their subsequent direction of movement.

  • Publication number: 20030113410
    Abstract: The invention relates to a method for the continuous production of infusion bags, in particular for tea, by depositing single substance quantities (3) on a filter paper web (2) and forming a tube as well as forming individual chambers (6), which are closed on all sides and at least contain one substance quantity (3), respectively, and which are attached to a carrier material (12). According to the invention, the chambers (6) are formed by a transverse seam (9), which simultaneously comprises the rear seam (9a) of the one infusion bag and the front seam (9b) of the succeeding infusion bag and a perforation (9c) interposed between both seams (9a and 9b), at which the infusion bags are separated in course of the process.

  • Publication number: 20030113412
    Abstract: The present invention relates to a method for attaching a label (5) to the free end (3e) of a thread (3), the other end of which is attached or attachable to an infusion bag (1), in particular for tea, wherein thread (3) having its free thread end (3e) placed on the one side of label (5) is taken by a needle penetrating label (5) and is pulled in a loop (3f) through label (5), loop (3f) is then introduced from the other side in two slits (5a) in the marginal region of label (5), such that its closed portion is again placed on the one side of label (5) and wherein the loop is afterwards tightened by pulling thread (3). The invention also relates to an infusion bag (1), in particular for tea, as well as a label (5) for an infusion bag.

  • Publication number: 20020005101
    Abstract: This invention relates to a system for the continuous separation of strings of material, subdivided into individual string subsections or pockets by transverse perforations, especially in the context of the production of tea filter bags, incorporating a continuously rotating wheel (1) and, beside the wheel (1), grippers (3) which are tiltable relative to the wheel (1) and serve to grasp the longitudinal sides of a string subsection to be separated from the string at a predefined point near the perforation, said string subsection permitting separation by means of the relative movement between the grippers (3) and the wheel (1).
