Definitions

  • the invention relates to a double chamber infusion bag according to the generic term of Claim 1.
  • the invention further relates to a method for producing, Filling and closing such double chamber infusion bags, as well as one Device for performing the method.
  • Tea infusion bags are used in various forms.
  • the two adjacent to each other, side by side have lying chambers, each containing a quantity of dried and crushed tea leaves included.
  • the two chambers are on the floor a cross fold, also called bottom fold, connected and connected closed at the head end by a connection at the one Thread is attached with a label.
  • This is usually done in two Operations manufactured head closure fold formed by in a first
  • the corners of the infusion bag are folded in one step
  • the second step is the trapezoidal part that remains at the top is folded, whereupon the folded parts by a locking clip connected with the simultaneous attachment of a thread end become.
  • the double chamber infusion bag thus constructed consists of one easily permeable material, which allows the infusion liquid, the leaching out substance to be leached, especially the tea, and the therein dissolve contained substances. In particular, this is filter paper material used.
  • Such a double-chamber infusion bag is from the German patent known to the applicant 1 001 944.
  • One is made uniform for its manufacture forward moving filter paper web bulged at its edges, become equal quanta of the leached substance at regular intervals applied to the fabric and is made by folding the longitudinal edges a continuous tube is formed on the fabric. Then a two Cut off piece of tube containing substance quanta this piece is folded transversely so that two, one each, due to the transverse folding Chambers containing substance quantum arise, placed side by side become.
  • the ends of the hose section or the ends that were still open both chambers are merged and together through a connection closed off from the folded corners and the one above folded trapezoidal end piece and the hammered locking clip is made of metal.
  • GB 881 748 A is a double-chamber infusion bag known according to the preamble of claim 1, the both chambers with each other via a transverse fold made on the bottom keep in touch. On the head side, the two chambers after the Fold up by a single transverse heat seal closed and connected, with an opening in the middle is provided, through which a label thread can be passed.
  • a double chamber infusion bag is known from DE 691 00 244 T2, whose two chambers are closed against each other at the bottom fold.
  • the two long sides are sealed by two edge seals and the The head end and the bottom end of each chamber each have a profile end seal closed, the head seal has a convex profile, while the bottom-side sealing with a concave profile is carried out to lateral
  • the appropriate folding a W-shaped Form bottom fold.
  • Double chamber infusion bags are two pairs of single-layer filter paper webs, a total of four webs, made of heat-sealable filter paper material guided one above the other by means of running in the longitudinal direction Heat seals on the edges (edge seals) two tubular sheets to build.
  • tea portions are placed on the at spaced intervals lower lane of each pair. With transverse heat seals between the tea portions after sealing the longitudinal edges Chambers formed and closed. Then the two tubular tracks with the chambers aligned with the existing ones Cross seals cut to separate the pairs of chambers and the chambers on the lower extensions are together welded while their upper ends are still left unconnected.
  • the two chambers forming the infusion bag are around 180 ° around each other, so that the upper ends of each pair of Chambers are brought together and sealed together can.
  • the thread is also prepared with a heat seal or Adhesive attached to the top of the bag.
  • the disadvantage here is that none Leaching of the tea can take place over the floor area of the chambers, because they are completely separated from each other by a heat seal.
  • the for Leaching, i.e. the passage of liquid permeable bag areas are strong due to the all-round sealing reduced.
  • the method of manufacture is technically complicated and complex, so that production on a high-speed machine only is difficult to do.
  • the invention is based on the task , while avoiding the disadvantages mentioned, of developing a double-chamber infusion bag of the type described at the outset, in particular for tea, which meets all the requirements for successful leaching through large, permeable surfaces and a simple closure connection for simultaneous attachment of the label thread without a metal clip.
  • the method and the device for producing such an infusion bag according to the invention is based on the object of enabling production on a high-speed machine, in particular at more than 500 pieces per minute.
  • the first task is according to the invention by the characterizing features of Claim 1 solved.
  • one Double chamber infusion bag with the cross fold on the bottom with each other connected chambers both ensured successful leaching as also a technically simple lock connection of the chambers at the head end created with a surprisingly functional thread attachment.

  • the Free thread ends can be done with a roof-like folded label strip be connected, preferably the thread ends from the sides inserted into the fold of the label in opposite directions and attached there, in particular are heat sealed so that the ones extending underneath Roof areas of the label remain free and like a rider on the
  • the head end of the bag can be placed on the inside of the thread loop.
  • Thread loop meandering in the interior between the two chambers to lay.
  • the double-chamber infusion bag is made of a heat sealable fabric, in particular filter paper web, which is produced approximately centrally around its longitudinal axis is folded or folded and by means of a longitudinal edge seal to one Hose is formed by an approximately central transverse fold in two interconnected chambers is divided, the head ends by the Cross heat seal are closed and at the head end by another transverse heat sealing as a closure connection with an inner, pull-out thread loop are connected.
  • the finished double chamber infusion bag has one on each chamber Longitudinal edge sealing and transverse head seals on while the other long side and the bottom are created by folding.
  • the longitudinal edge seal is preferably folded inwards around the Double chamber tea bags to keep the width smaller and the longitudinal seam through the folding to give an increase in strength, being optical identity to known infusion bags and the same dimensions can be achieved.
  • the further object is achieved by the method according to claim 7 and solved by the device according to claim 11.
  • the process is preferably carried out in two lanes and the flat path to Formation of a double hose widened to about four times the bag width.
