Definitions
- the invention relates to a single-chamber infusion bag, in particular for tea, with a chamber containing a substance quantum, consisting of a pair oppositely arranged walls are formed, which on their Circumference along their long and short sides are interconnected and form an enclosed space containing the substance quantum, where at least one, preferably both long sides with one that Chamber volume with the same fold-out width increasing the fold are provided.
- the invention further relates to a method for continuous Manufacture, fill and seal of such single-chamber infusion bags, especially for tea.
- Tea infusion bags are used in various forms, in particular the use of double-chamber infusion bags has prevailed, the two arranged side by side have lying chambers, each containing a quantity of dried and crushed tea leaves included. Because of the complicated manufacture but continue to use simple single-chamber infusion bags that are used in the Usually consist of a rectangular filter paper strip that is folded in the middle and including a quantum of substances at the three initially open Sides, especially by heat sealing, is closed or from two Filter paper webs into a four-sided sealed or round bag be sealed by heat sealing.
- EP 0 806 351 A1 describes a double-chamber infusion bag, in particular known for tea, in which the long sides by a longitudinal edge seal are closed. To increase the chamber volume is already there proposed to fold the longitudinal edge seal inwards, whereby the Teabag gets smaller in width.
- the disadvantage is that with this measure Sufficient for a double-chamber bag, but in principle only in limited chamber enlargement is possible.
- the invention is based on the object of developing a single-chamber infusion bag which is far easier to manufacture and which, while maintaining the usual external dimensions without increasing its length or width in the packaging state, provides a chamber volume which is considerably larger than that of simple folding, which enables the infusion liquid to excellently digest the leached substance, in particular the tea, and to dissolve the substances contained therein, which should be technically simple, continuous producibility.
- the accordion or bellows-like folding of one or both long sides at least five preferably has seven fold lines.
- the bag strength of the additional advantage associated with that worked little depth into the interior of the bag can be and thus increases the effective filling volume for the substance can be.
- a simple fold which is essentially V-shaped, the depth of the fold into the chamber becomes too great considering the prepositioned substance so that either the amount of substance decreases must be or the folding process is disturbed by the substance.
- the single-chamber infusion bag according to the invention consists of a easily permeable, heat sealable filter paper material, which it the Infusion liquid allows the substance to be leached, especially the Tea that is easy to digest and that is suitable on the other hand Long side connections and transverse side connections by heat sealing to manufacture.
- the two mutually opposite chamber walls are preferably of the single-chamber infusion bag to produce the folding with linear congruent knockouts parallel to Provide longitudinal side connection, expediently a plurality mutually parallel, spaced congruent Pairs of line-shaped knockouts according to the number of intended Folding processes are arranged side by side. You can interacting pairs of knockouts same folding forces and not interacting pairs need different folding forces by the Knockouts are of different depths. Instead of Knockouts can also be linear mini perforations or Reduced thickness of the material according to the type of film hinge formation be applied.
- a thread with a Label attached to the infusion bag the label thread preferably is loop-shaped inside the chamber and by means of the Pull out label for use.
- the process step of Folding the long sides can be carried out in several stages by first in a first fold the longitudinal sides provided with longitudinal edge seals be pressed inwards so that a right-angled bend on the Internal knockouts are made and the tube has a cross-section gets rectangular shape and that then in further folding operations Longitudinal edge seals pressed further into the chamber and be brought out again, so that according to the knockouts zigzag-shaped Folding operations are carried out, preferably the Longitudinal edge seals are positioned in the median plane of the hose.
- the Invention proposed a duplex process control, thereby is characterized in that on a correspondingly broadened first web two Rows of substance quanta are placed symmetrically next to each other, that over the first track a correspondingly broadened second upper track is carried out that the knockouts are then made, the upper and lower web brought together and by means of two outer, in Longitudinal heat seals and a central, in Longitudinal heat seal together to form two tubes are connected, which are then cut centrally in the longitudinal direction and finally in the same way as with the simplex process the long sides folded in accordion or bellows shape, in Transversely heat sealed and in the transverse seals in a transverse direction Direction to be cut.
- 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 on their circumference connected to one another along their long sides 4, 5 and transverse sides 6, 7 are and such an enclosed space to form a chamber 8th form, which a substance quantum 9, namely a portioned amount of tea, contains.
- the one-chamber infusion bag 1 is therefore on its four sides sealed by heat sealing, namely by longitudinal edge seals 10, 11 on the long sides 4, 5 and two cross seals 12, 13 on the short sides 6, 7.
- the volume of the chamber 8 of such a single-chamber infusion bag 1 is significantly increased by the fact that on both longitudinal sides 4, 5 one Folding 14, 15 is formed, which is accordion-shaped in cross section, the longitudinal edge seals 10, 11 approximately in the central plane 18 of the Bags are and are inserted into the chamber 8 such that the usual external dimensions of such single-chamber bags are maintained and thus, despite the increase in chamber volume, no increase in it Length or width in the packaging state is given. So that is achieved that the substance quantum of tea in the chamber is outstanding due to the Infusion liquid is to be digested and the substances contained in it solve optimally.
- the chamber volume is more than 30% compared to a conventional single-chamber infusion bag without Enlargement enlarged, with the zigzag-shaped folding 14, 15 each according to the number of folds - at least five folds on one side - one greater variability in the design of the chamber volume can be achieved.
- the single-chamber infusion bag 1 has one on it attached thread 16 provided with label 17, the hanging of the bag into a cup, jug or similar vessel.
- FIGS. 3, 4 and 5 of the drawing illustrate a single-row or simplex production
- Fig. 5 of the drawing a bag production in two parallel rows continuous, also called duplex production.
- the starting point for the production of single-chamber infusion bags 1 is a first one heat-sealable filter paper web 19 by a not shown Material roll drawn off by a pulling device and as a web one Dosing device for tea is supplied. From this are positioned Substance quanta 9, i.e. piles of tea, at regular intervals in one Row placed on the filter paper web 19. From a not shown Another roll of material is a second, upper heat-sealable from above Filter paper web 20 of identical size and transport speed lower filter paper web 19 and fed in parallel by means of a roller this arranged so that there is a uniform forward movement of the Filter paper web 19 and the filter paper web 20 arranged one above the other and gives each other opaque.
- Both the lower sheet 19 and the upper sheet 20 are pre-dosed or before merging in an embossing device in the longitudinal direction one or more knockouts 21 on both long sides congruent provided whose positions are made so that they ultimately the Determine the width B of the finished single-chamber infusion bag 1.
- the line-shaped Knockouts 21 represent crease edges that form the folds 14, 15 in the later stage of the procedure.
- the lower web 19 and upper web 20 in a device having heat sealing rollers brought together and by means of the longitudinal Longitudinal edge seals 10 and 11 to each other at the web edges a hose 22 connected at regular intervals in a row contains the substance quanta 9. 3 and 4 of the drawing reached stage of manufacture I.
- the process step of folding the long sides 4 and 5 done in two stages. This will be done first in a first convolution the provided with the longitudinal edge seals 10, 11 longitudinal sides 4, 5 of Hose 22 pressed inward so that a right-angled kink
- the knockouts 21 are carried out and the tube has a cross section rectangular shape according to manufacturing stage II in Fig. 3 and 4 of the drawing receives.
- the longitudinal edge seals 10, 11 continue to inside in the chamber 8 in a second folding according to manufacturing stage III pressed in and for example by folding swords, rollers and the like performed until the folds 14, 15 the desired zigzag Have cross-section, the longitudinal edge seals 10, 11 approximately in the Middle plane 18 of the chamber 8 are positioned in the finished bag.
- the hose 22 created in this process stage with the bellows Folds 14 and 15 are then in with a cross sealer regular intervals, each covering a quantity of substance 9 - according to the height H of the bags to be produced - in the transverse direction heat-sealed and the transverse heat seals are centered cut so that hose parts are formed, each one Have chamber 8 containing substance quantum, on the long sides with Longitudinal edge seals 10, 11 and on the transverse sides with transverse seals 12, 13 provided and are closed on all sides.
- the thread 14 previously laid out with label 17 for each single-chamber infusion bag 1 to attach to one of the cross seals, including a loop Removable label thread 16 is provided from inside the chamber 8 can be.
- first web 23 and second web 26 brought together and by means of two outer, running in the longitudinal direction Heat seals 28, 29 and a central longitudinal one Heat seal 30 joined together to form two tubes that then in the middle in the longitudinal direction by means of a cutting device can be cut and separated.
