Definitions

  • the present invention relates to an infusion bag, preferably a double-chamber infusion bag, especially for making tea, with at least one consisting of a filter material containing a substance quantum Chamber, which is closed at the head end, on which a thread with an as Handle and / or informational label is attached.
  • Tea infusion bags are used in various forms.
  • the two chambers are on the floor with a cross fold, also called floor fold, with each other connected and closed together at the head end by a connection, to which a thread is attached with a label.
  • This becomes a two-step head lock fold is formed by in one first operation, the corners of the infusion bag are folded and in one second step the trapezoidal part that remains at the top is thrown. Then the folded parts are connected tacked together while fastening one end of the thread.
  • a double chamber infusion bag is for example from the GB-A-1 157 513 known. It's made of a slightly permeable material, which enables the infusion liquid to extract the substance to be leached out, especially the tea, to digest and dissolve the substances contained therein.
  • closure clamps made of metal - so-called Booklet - to be used in the area of the fold of the head end of the Aufguß milks or be arranged on the label.
  • connection or attachment of the infusion bag to the thread or the label is in the known connection and / or fastening options not always guaranteed. So is especially when using a closing clip does not ensure that the thread is clamped securely, so that the thread slides out of the clip relatively easily and thus can detach from the label or the infusion bag.
  • connection media that is Closure clamps have a taste-changing or influencing effect have and disrupt the consumer.
  • the invention was based on the object, a generic Tea bags, preferably double-chamber tea bags, to improve so that a reliable one that changes or influences taste Effects of neutral head closure of the infusion bag with integrated Thread holder is created.
  • the object is achieved by the invention in that the head end of the Chamber is closed by means of a sheet of heat-sealable filter paper, which also attaches the thread to the head of the infusion bag.
  • heat sealing involves joining two substances together Temperature understood.
  • the areas to be connected are assigned to the Softening temperature of the material heated and by pressure with each other connected, the materials not at the applied temperature become plastic.
  • the heating of the material can be done in different ways and Way, for example by means of heated metal plates Heat impulses or by means of high frequency.
  • the use of a sheet of heat sealable filter paper as Head closure of the infusion bag has the essential advantage that none media and / or materials that change or influence taste indirect or direct contact with that contained in the chamber Enter the quantum of substance and may have a disruptive effect because heat-sealable filter paper no taste-changing substance having. Furthermore, complex operations for closing the Avoid tea bags. Through the flat distribution and the connection with the filter paper is also guaranteed that the connection of thread and Tea bags do not dissolve even at high temperatures. Furthermore, the Use of the sheet of the invention an extremely customizable closure created that can easily accommodate larger loads without to be destroyed or damaged. This is partly due to the areal Attachment achieved which greater cohesive and / or adhesive forces has closures than previously known.
  • the sheet of heat-sealable filter paper used for attachment can have any shape, for example stripe-shaped, rectangular, be square, triangular or circular.
  • the infusion bag is as Double chamber infusion bag designed, the two of filter paper material existing, side by side, each one quantum of substance Containing chambers, which are joined together by a transverse fold on the bottom connected and their head ends together through the sheet heat-sealable filter paper are sealed and attached to each other.
  • the head ends of the chambers can pass through together completed a transverse locking seam and by a rectangular sheet.
  • the head ends of the chambers by extending over the length of the head end of the chambers Rectangular and cross-folded sheet closed in the kind of a rider is placed on the head ends of the chambers.
  • the provided with a transverse transverse locking seam Head ends of the chambers by a tubular strip To close the sheet that is pushed over the head ends.
  • the label on the thread is preferably also made of a sheet of heat-sealable material Material attached.
  • the double chamber infusion bag 1 shown in Fig. 1 has two, side by side adjacent chambers 2 and 3 on the bottom 4 via a W-shaped Cross fold 5 are connected to each other and each a predetermined quantity a substance to be leached out by an infusion liquid, in particular tea, contain.
  • the head ends of the two chambers 2 and 3 are together through a transverse closing seam 6 closed and by a rectangular sheet 7 made of heat-sealable filter paper attached to each other. With the sheet 7 is simultaneously a thread 8 in the region of the closing fold 6 of the Attached top of the double chamber infusion bag 1.
  • the thread 8 is not explicit at its other end by means of one here Connection 10 shown, for example a booklet or a knot with a label 9 used for handling and / or information.
  • the Label 9 can consist of heat-sealable material and the thread directly be sealed.
  • Fig. 2 shows a further embodiment for a fastening according to the invention of the thread 8 and a closure according to the invention of a double-chamber infusion bag 1 by means of a sheet 7 of heat-sealable filter paper.
  • the leaf extends over the length of the head end of the double-chamber infusion bag 1 extending rectangular sheet 7, which has a transverse fold 11 has and like a rider at the head of chambers 2 and 3 of Double chamber infusion bag 1 is placed and so the chambers 2 and 3 closes.
  • the thread 8 is removed from the transverse fold 11 recorded and thus attached to the double chamber infusion bag 1.
  • connection 10 between the thread 8 and the label 9 also by a rectangular sheet 12 made of heat sealable Created material that attaches the thread 8 to the label 9.
  • the head lock fold 6 in the embodiment according to FIG. 3 thereby made that the chambers 2 and 3 of the double-chamber infusion bag 1 of the head ends are only folded down without the corners being folded in beforehand were.
  • connection 10 for fastening the thread 8 given on the label 9 by a knot 13.
  • the label 9 has a Opening 14 through which the thread 8 is inserted and through the knot 13 is secured against slipping out.
  • the sheet 7 is the length of the Head end extending as a tubular strip, which over the head end of the double-chamber infusion bag 1 and heat sealed by chambers 2 and 3 closing and attaching the thread 8, with the Double chamber infusion bag 1 is connected.
  • all variants of the different embodiments can be for attaching the thread 8 to the double chamber infusion bag Combine 1 or thread 8 on label 9.
  • connection 10 between the thread 8 and the label 9 also the previously Common connection or fastening options with a Closure clip, the so-called booklet, or the use of Use glue, knots and the like. It is only essential that the sheet 7 serving to fasten the thread 8 does not change the taste triggering or influencing effects. This also includes those effects that are only perceived as disturbing by the consumer.
