Definitions
- the invention relates to a method for continuous production, filling and Closing single-chamber infusion bags, especially for the preparation of Tea.
- the small chamber volume provides only a limited expansion option when the tea swells Available so that the valuable tea is insufficient from the substance can be extracted and transferred to the surrounding tea water.
- the small chamber volume also means that none can be Leaf tea varieties as a quantum of substance, but only use fine cuts whose Quality is less than leaf tea.
- a single chamber infusion bag is known in which the Long sides of the chamber are formed by tubing by the two longitudinal edges of a heat-sealable material web to the inside Folded in the middle and joined together by heat sealing be, with one on each long side in the chamber itself extending folding is provided.
- the tube is formed Fold-free, seal-free or seam-free long sides, in which in a simple way inward-extending folds can be made, which both a simple continuous manufacture and a large one Chamber volume can be achieved.
- the disadvantage is that the central longitudinal heat seal which are available for the passage of the leaching liquid Area of one chamber wall is significantly reduced.
- the invention has for its object to provide a method for the continuous manufacture, filling and closing of single-chamber infusion bags, by which the passage area is enlarged to improve leaching and a broad heat sealing strip on the chamber wall is avoided.
- portioned substance quanta of the substance to be leached out are deposited at regular intervals on an initially flat material web, in particular filter paper web, optionally after bulging of their side edges, so that a continuous tube is subsequently formed from the web by the two longitudinal edges are folded inwards towards the longitudinal center and bent at an unequal length from the plane of the bag surface parallel to one another and connected to one another by knurling, so that the two longitudinal sides are provided with an inwardly extending fold-in during the tube formation or subsequent to the tube formation, that the tube is then heat-sealed in the transverse direction at regular intervals, each measuring a quantity of substance, and that the cross-heat seals are cut in the middle and such tube parts are formed that each ils have a chamber containing a substance quantum.
- the method of the invention can be carried out at high speed because the middle-longitudinal connection is carried out by mechanical knurling and - different than when producing a medium-length heat seal - none time-consuming transfers of high amounts of heat as well as cooling processes must be carried out to create the longitudinal seam.
- DE-A-1 800 032 shows a single-chamber infusion bag in which the Tube is already formed by a knurled seam.
- Both long sides are preferably accordion-like or bellows-like folded in, the flat material web beforehand with linear Longitudinal knockouts according to the number of intended Folding processes can be provided.
- 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 Tube formation of a web 4 of the filter paper material result by the turned over both longitudinal edges 5, 6 inwards towards the longitudinal center 7 and there are connected to one another by a central longitudinal knurled seam 8, the foot end 9 and the head end 10 each having a transverse one Heat seal 11 or 12 are closed. That way is a enclosed space formed to form a chamber 13, the one Substance quantum 14, namely a portioned amount of tea, contains.
- the A single-chamber infusion bag 1 is therefore on its two long sides 15 and 16 due to the tube formation without seams and sealing-free in that the central longitudinal knurled seam 8 is provided, while the closure on Foot end 9 and head end 10 through the transverse heat seals 11 and 12 he follows.
- the volume of the chamber 13 of such a single-chamber infusion bag 1 is significantly increased in that one on each of the long sides 15, 16 Folding 17, 18 is formed, the V-shaped to accordion-shaped Cross section is and approximately in the central plane in the chamber 13 of the bag extends inwards.
- the folds 17, 18 are so made that the usual external dimensions of such single-chamber infusion bags be maintained and thus despite the increase in Chamber volume no increase in its length or width in Packaging condition is given. This ensures that Substance quantum tea in chamber 13 excellently through the Infusion liquid is to be digested and the substances contained in it solve optimally. This is also due to the fact that the long sides 15 and 16 and the chamber wall 2 are free of heat seals.
- the single-chamber infusion bag 1 with a attached thread with label (not shown), which hanging the bag in a cup, jug or the like enable,
- Einzig-Aufguß lines 19 illustrates that the touching, in the longitudinal center 7 merged knurled longitudinal edges 5 and 6 into one are formed perpendicular to the web 4 upstanding longitudinal seam 20, the subjected to knurling from both sides by means of knurling wheels 21, 22 becomes. Then the knurled seam essentially folds into the Level of the bag instead, as can be seen in FIG. 2.
- the manufacture of such a single-chamber infusion bag 1 or 19 is below based on the description of FIGS. 4 and 5 of the drawing clarifies.
- the starting point of manufacture is a heat sealable one Filter paper web 4 by a roll of material, not shown, by a Pulled device and as a flat track of a metering device D for Tea is fed.
- Dosing device D with an embossing device, not shown in Longitudinal direction left and right parallel to the longitudinal edges 5, 6 of the Filter paper web 4 are each made a linear pre-embossing acts as a folded edge to the formation of the folds 17 and 18 in to facilitate the later stage of the procedure.
- the material web 4 becomes a hose by means of forming a tube inwards according to the arrows in Fig. 4 I of the drawing turned on both sides until the longitudinal edges 5 and 6 in come together in the middle.
- the longitudinal seam 20 becomes the longitudinal seam 20 according to FIG. 3 with an uneven height brought up from the bag level and arranged parallel to each other Longitudinal edges formed, then by a central longitudinal knurled seam 8, if necessary also by additionally folding the Longitudinal edges to make the connection.
- hose 23 created in this process stage with the V-shaped Folds 17 and 18 are then in with a cross sealing device regular intervals, each capturing a quantity of substance 14 in Transversely heat sealed and these cross heat seals 11, 12th cut in the middle so that hose parts 24 are formed, each one have a chamber 13 containing quantum of substance 14, on all sides is closed by two heat seals and the knurled seam.
- This Process stage is shown in Fig. 4 III of the drawing.
- a previously designed thread with a label for each single-chamber infusion bag 1 or 19 to attach to one of the cross seals, including a Label thread which can be pulled out in a loop from the interior of the chamber 13 can be provided.
- FIG. 5 of the drawing another can be used to improve the knurling Stapling the longitudinal edges 5 and 6 together by using a H be done before knurling by softening the Plastic fibers the filter paper material leads to an adhesive connection. This allows the longitudinal edges to be folded and knurled together perform more precisely and safely.
