Definitions
- the invention relates to a single-chamber infusion bag, in particular for tea a chamber containing a substance quantum, which consists of a pair of each other oppositely arranged walls is formed, which on its circumference are connected to each other along their long and short sides and one enclosed space containing the substance quantum, whereby at least one, preferably both long sides with a chamber volume with a constant bag width increasing at least five, preferably seven concertina or bellows-type concertina to be folded trained folding are provided.
- the invention further relates to a method for the continuous production, filling and sealing 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 simple single-compartment infusion bags continue to be used, which are usually consist of a rectangular filter paper strip, which is folded in the middle and including a quantity of substance on the three initially open sides, is sealed in particular by heat sealing or from two Filter paper webs into a four-sided sealed or round bag be sealed by heat sealing.
- a tea bag which consists of tubular Material is made at its lower end by folding or welding is closed and is filled with tea via the upper open end, after which a special closure part is used to the upper end of the Seal the bag.
- a tubular bag that is Chamber volume is significantly increased compared to known tea bags, but is on the other hand, an elaborate production with several operations required that hinder continuous production.
- the known tubular bag dimensions much larger than has the usual single-chamber infusion bag and approximately in length Corresponds to the inside height of a glass or jug in which the bag is inserted becomes.
- a single-chamber infusion bag of the type mentioned with accordion or Bellows-like folds are known from GB 789 492 A.
- the concertina or bellows-like design the long sides of the single-chamber infusion bag significantly increase the chamber volume increase without increasing the outside dimensions of the bag. So that is in addition to the flexibility in the design of the bag thickness, the additional advantage connected that with a small depth of folding in the interior of the bag can be worked into and thus the effective filling volume for the Substance can be enlarged.
- the depth of folding into the chamber is too great Given the prepositioned substance, so that either the amount of substance must be reduced or the folding process is disturbed by the substance becomes. In practice, however, it has been shown that this zigzag shape is extremely difficult Form fold so that a predetermined bag width is observed.
- EP 0 806 351 A1 describes a double-chamber infusion bag, in particular for Tea, known 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 technically simple and continuously producible single-chamber infusion bag which, while maintaining the usual external dimensions without increasing its length or width in the packaging state, has an accordion or at least along one long side provides bellows-like folding to enlarge the chamber volume.
- the object is inventively achieved in a single-chamber infusion bag of the type mentioned in that the two opposing chamber walls of the single-chamber infusion bag are provided for producing the folding with linear congruent pre-embossings parallel to the longitudinal side connection.
- the knockouts on the oppositely arranged walls of the chamber it is possible in a simple manner, by inserting the longitudinal side connection into the chambers, to reliably and reproducibly fold the zigzag-shaped fold in at the predetermined locations, preferably on both longitudinal sides, with this the bag width can also be determined.
- a plurality are expediently parallel to one another, at a distance mutually congruent pairs of linear knockouts according to the number of intended folding operations side by side arranged.
- Interacting pairs of knockouts can be the same Folding forces and non-interacting pairs have different folding forces need in that the knockouts are of different depths.
- Knockouts can also be linear mini perforations or Stronger reductions in the material applied according to the type of film hinge formation become.
- the single-chamber infusion bag according to the invention consists of a easily permeable, heat sealable filter paper material, which it the Infusion liquid enables the substance to be leached out, in particular the tea, good to open up and on the other hand is suitable, the Long side connections and transverse side connections by heat sealing to manufacture.
- a thread with a Label attached to the infusion bag the label thread preferably loop-shaped inside the chamber and by means of the label is extractable for use.
- 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.
- FIG. 6 of the drawing A variant of the duplex method is shown in Fig. 6 of the drawing.
