Definitions

  • the invention relates to an infusion bag, in particular for the preparation of Tea, with a chamber containing a quantity of substance, consisting of a pair arranged opposite to each other by folding one in the middle rectangular filter paper strip formed walls, which at their three initially open pages including the substance quantum Heat seals are closed, with a thread at the head end with a Label is attached by means of the heat seal.
  • the invention further relates to a Process for the continuous production, filling and sealing of such single-chamber infusion bags, especially for tea.
  • the Chamber volume is also small, so only a limited one Expansion is available when the tea swells and the valuable tea substances are insufficiently extracted from the substance and can be transferred into the surrounding tea water. Because of the low Chamber volumes can also not be considered leaf tea types Quantum of substance, but only fine cuts, use their quality is less than that of leaf tea.
  • the invention is based on the object of improving the single-chamber infusion bag of the type mentioned at the outset in such a way that the surfaces available for passage of the leaching liquid into the chamber are enlarged, the chamber volume to improve the leaching capacity while maintaining the usual Outside dimensions is increased and at the same time there is a simple, continuous producibility from only one heat-sealable material web.
  • the object is inventively achieved in a single-chamber infusion bag of the type mentioned in that the heat sealing free folded side of the pouch is a longitudinal side that these longitudinal side magnification with a chamber volume, V-shaped in cross section, or accordion-shaped, extending up into the chamber Folding is provided that the sides sealed by heat sealing are the other long side as well as the head end and the foot end of the bag and that the thread is attached to the heat sealed long side with the label.
  • the infusion bag itself providing larger entry surfaces for the infusion liquid into the chamber by heat-sealing only one long side and the two shorter transverse sides of the bag and also on the A V-shaped or bellows-like fold-in is provided on the heat seal-free longitudinal side, which increases the chamber volume and the passage surfaces.
  • this fastening can also be carried out in a known manner on a heat-sealed transverse side, for example the head end.
  • the accordion or bellows-like folding of the Have at least five, preferably seven fold lines on the long side.
  • the additional Advantage associated with a lower depth of folding into the interior of the bag can be worked into and thus the effective Filling volume for the substance can be increased.
  • the label thread looped inside the chamber and by means of the label extractable for use.
  • the line-shaped knockouts are advantageously made in accordance with the Number of folding operations next to each other and at a distance to each other on the flat material web in the not for positioning the Substantial quantum provided half made.
  • the Invention proposed a duplex process control, thereby is characterized by a flat heat-sealable material web a larger fourfold loot width is assumed that on each half a label thread is placed on the material web by means of a thread layer, that in the next process step portioned substance quanta of leached substance in two rows parallel to each other in uniform Spaces on the material web adjacent to the longitudinal center symmetrically are placed side by side, with the label threads from each half of the web the area of the chamber to be formed later on for heat sealing provided longitudinal side of the material web are led out and under Form a loop back into the chamber area of the material web at one Are introduced at a later stage in a process ongoing heat sealing is carried out that subsequently to the Positioning the substance quantum rows the two outer quarters of the Material web are folded inwards to the folding axis and there on impact, however positioned leaving a gap and by means of a medium length heat
  • each a quantum of substance Detecting distances are heat sealed in the transverse direction and that the Cross heat seals are cut in the middle and such tube parts are formed, each a chamber containing a substance quantum exhibit.
  • the label threads that are led out of the material web are preferred already with labels when threading, after the folding process in an intermediate step before the formation of the central longitudinal section be folded back so as not to disturb the cutting process or when Cutting process not to be damaged.
  • the one-chamber infusion bag 1 shown in Fig. 1 of the drawing made of heat sealable filter paper material and has two each other oppositely arranged chamber walls 2, 3 through folding in the middle of a basically rectangular filter paper strip result, the folding taking place about a longitudinal side 4 of the bag 1.
  • the opposite long side 5 is closed by a heat seal 6, as well as the head end 7 by a cross heat seal 8 and the foot end 9 through a cross heat seal 10.
  • a heat seal 6 as well as the head end 7 by a cross heat seal 8 and the foot end 9 through a cross heat seal 10.
  • an enclosed one Space formed to form a chamber 11 which is a substance quantum 12, namely a portioned amount of tea.
  • the single chamber infusion bag 1 is therefore at its one, on the left in the drawing Long side 4 heat seal-free, while the longitudinal heat seal 6 and the transverse heat seals 8 and 10 the closure at the head end 7 and Foot end 9 is done.
  • the single-chamber infusion bag 1 with a attached thread 14 may be provided with label 15, which the Hang the bag in a cup, jug or similar container enable.
  • the manufacture of such a single-chamber infusion bag 1 is as follows based on the description of Fig. 2 of the drawing. Starting point the manufacture is a flat heat-sealable material web 15 in shape a filter paper web that has a width that is slightly larger than that double the width of the bag is also used to fold the material To have available.
  • the flat material web 16 is not by means of a illustrated thread layer of the label thread 14 on the right in the drawing Half of the web deposited on which portioned in the next process step Substance quanta 12 of the leached substance in uniform Intervals can be arranged in series.
  • the heat seal-free fold is made Long side 4 with the one extending inwards into the tube Fold 13 provided.
  • the hose 20 becomes regular, one at a time Substantially quantum-12 distances heat-sealed in the transverse direction and the transverse heat seals 8 and 10 are cut in the middle, so that Tubular parts 21 are formed, each having a substance quantum 12 contain containing chamber 11.
  • Longitudinal heat seal 6 ensures that the thread 14 is fixed at the foot end 9 and is pulled out at the head end 7 through the longitudinal heat seal is, laterally outside the label 15 on the eyelet of the thread in known Is attached by heat sealing.
  • the packaging finds that Fold the label inside instead so that it is in the packaging condition rests on the wall 2 of the chamber 11.
  • portioned substance quanta are 12 in two rows 29, 30 parallel to each other at equal intervals on both Halves 25, 26 of the material web 24 symmetrically adjacent to the longitudinal center L. placed side by side.
  • the Substance quantum rows 29, 30 become the two outer quarters of the Material web 24 folded inwards about the respective folding axis 19 and in the longitudinal center L butt, but leaving a gap 31, the Fig. 3 II of the drawing can be removed, positioned and optionally pre-fixed.
  • This is followed by the process step of creating a medium-length heat seal 32 with which the folded edges with the underlying parts of the material web are connected.
  • both tubes 33, 34 are then in regular, each heat-sealing distances in the transverse direction, the transverse heat seals 38 are cut in the middle and such Tube parts are formed, each containing a substance quantum 12 Have chamber 11.
  • the labels 15 are in an intermediate step after the folding process and before the formation of the central longitudinal section has been folded back so as not to interfere with the cutting process or when Cutting process not to be damaged.
  • Fig. 4 of the drawing shows a perspective view in the duplex method manufactured single-chamber tea bags in the arrangement in which they Manufacturing machine at the end of the process to leave one Packaging to be fed.
