Description

The present invention relates to a brew bag with the preamble features of claim 1. Such a brew bag is from the DE 299 05 470 U1 known

Such infusion bags contain a substance which is leached by the infusion liquid during the pouring of the bag. The substance usually used is tea.

A generic infusion bag has two chambers extending substantially parallel to one another and is also referred to as a double-chamber bag. In the production of these double-chamber bag a web-shaped wrapping material is covered with the substance to be laxed, formed into a circumferentially closed, the substance enveloping hose, which is folded in a subsequent manufacturing step to form the two chambers substantially in parallel contact with each other. In this case, in the region of the bottom, a bottom section is formed from the one longitudinal section of the enveloping material, which connects the chambers to one another at the bottom and these are spaced apart during pouring, so that the infusion liquid can also reach the opposite inner sides of the double-chamber bag. With a view to compacting the individual infusion bags as compact as possible, this bottom section is regularly provided with a bottom fold which extends to the inside of the infusion bag. When pouring the infusion bag and not least due to the swelling of the substance aufzugießenden this Bodenfalz is reset and the bottom portion should then extend at least after the ideal idea then substantially straight between the two chambers.

In the case of infusion bags of the aforementioned type, there is basically the problem that after the end of leaching, the infusion bag has to be lifted out of the infusion liquid in order to avoid the undesired leaching of bitter substances. The remaining liquid contained in the infusion bag drips relatively slowly out of the infusion bag and so usually the infusion bag is wrung out. It is known to insert the infusion bag for this purpose in a spoon and put the thread at least once around the infusion bag and then tighten it, so that the content of the infusion bag is compressed and the remaining liquid contained in the infusion bag is wrung out.

In the prior art, other proposed solutions are known in which the wringer is part of the delivered infusion bag. Thus, with the going back to the applicant DE-U-298 19 128 proposed a unit of infusion bag with outer packaging, which receives both the bag and the thread and the edge of which forms the label. To remove the infusion bag, the outer packaging is torn open and removed the infusion bag. The outer packaging can be inserted during leaching in the infusion liquid, for example, over the spout of a pot and thus the free end of the thread are secured against the pot. Thereafter, a corner of the overwrap receiving the free end of the thread is removed from the overwhelming portion of the overwrap by tearing the paper stock. The rest of the outer packaging is pushed over the infusion bag, so that the infusion bag is received in the outer packaging. The user can now press from the outside against the outer packaging and wring out the infusion bag manually, without wetting his fingers with the infusion liquid or his fingers immediately suspend the temperature of the infusion.

An alternative solution is from the DE-20 2004 002 533 known. This prior art follows essentially the aforementioned proposed solution, according to this recent proposal, the outer packaging is formed so that the brewing bag for safe flavor closure is tightly received in the outer packaging and the outer packaging is further formed from a relatively stable cardboard material, which after opening the flavor seal can be folded into a round disc. This round disc can be placed on a cup or a jug, so that not only the free end of the thread is held stationary and outside the pot, but also the pot or the cup is closed during leaching of the substance.

The from the DE 20 2004 002 533 Although known solution suggests a more even distribution of contact pressure when wringing the infusion bag and thus it is better possible to wring the residual liquid from the infusion bag. When wringing out, however, the shape of the infusion bag remains substantially unchanged, whereby the effectiveness of the wringing suffers.

From the DE 296 01 442 is a kneadable teabag known that has a thread, which is passed through two recessed in the region of the top insertion holes of the teabag and is secured to the bottom portion. Here, the thread is in a formed between the opposing chambers V-shaped inwardly folded fold. The tea bag protruding ends of the thread are each attached to a label portion. The two label sections can be separated at a perforation and to wring these label sections are pulled in the opposite direction. As a result, the tea bag is pulled with its bottom portion in the direction of the top and wrung out. However, this wringing leads to a significant stress on the recessed on the bag insertion holes and thus can lead to the destruction of the bag material and the emergence of tea leaves, which is not desirable. A similar wringing tea bag is of the generic type DE 299 05 470 U1 known.

In the market solutions are known in which the at least one thread is settled in a Einkammerbeutel. Thus, there are teabags which contain in the one chamber two threads extending along the longitudinal sides, which are incorporated in the area of the bottom of the bag into the bottom-side closure and thus connected to the wrapping material. At the opposite end, the two threads are led out of the Einkammerbeutel and fixed on opposite sides of a label. The label can be severed between the ends. Thereafter, the two parts of the label to be performed in the opposite direction. This is intended to wrinkle the infusion bag. In an alternative embodiment, the ends of two threads are each received in a top seam provided on the top and connected to the Hüllstoff, of which a thread immediately with the label and another thread initially looped in the bag and then through the top seam to guided outside and connected to the label. With this embodiment, the residual liquid can be wrung out at most insufficient.

The BE 895 865 A2 discloses an infusion bag which is closed at its top, wherein at the top of the infusion bag attached at its free end with a label thread is attached. The label has two releasably interconnected portions, with a smaller portion located within the fold of the label and received within the larger portion which forms two label sheets which are foldable to one another. By loosening the two sections, the larger section can be moved towards the infusion bag along the thread. The label sheets lie on the outside against the infusion bag and serve as a support surface for expressing the same. The different movements of the larger label portion are resisted by holding the infusion bag to the small label portion.

Another solution reveals the WO 01/34486 A1 , This discloses a Doppelkammeraufaussbeutel whose broad sides are enclosed by a thread. The thread is first passed through two holes parallel to each other in the middle of the formed by a fold ends of the top of the infusion bag, so that the thread to the front broad side of the infusion bag out forms a loop and open the backseitigen broadside of the infusion bag two thread ends. The thread ends are guided parallel to each other laterally transversely to the rear broad side on this down to the bottom of the infusion bag. The bottom of the thread ends wrapped around by a respective laterally and in the front side tip arranged and pronounced hole, and then transversely to the front side parallel to each other a hole piercing the ends of the top of the infusion bag laterally below the fold. From here, the two thread ends each pass through one of two parallel arranged in a plate-shaped freely movable abutment holes and are finally fed to a label and attached to this.

The infusion bag is wrung by simultaneously pulling the label in one direction and moving the freely movable abutment in the opposite direction.

The present invention is based on the problem of specifying a brewing bag of the type mentioned above with good Auswringverhalten. In addition, the infusion bag should provide good handling. Preferably, the infusion bag should be designed so that the label during pouring can be secured in a simpler manner to a cup and / or jug.

To solve the above problem, the present invention proposes an infusion bag having the features of claim 1.

The label of the present invention comprises two releasably interconnected portions, the thread being passed through at least one passage opening recessed at one of the portions, namely the bag-proximate portion. Through this passage opening the thread is passed and attached to the other portion of the label. The two sections of the label are detachable with each other connected. This is understood to mean, in particular, an embodiment which, by means of a simple hand movement of the user, leads to a separation of the two sections. For example, both sections may consist of a cardboard cover and be connected to one another via a perforation or a tapered neck region. The connection of the two sections is preferably via a film hinge, which is formed from the material of the label (cardboard). The user can thus tear off the initially bag close portion of the other, then along the thread, ie move relative to the thread or threads and lead against the top of the chambers. As the relative movement between the wringing aid and the bottom portion of the chambers proceeds, the yarn secured relative to the bottom portion is tightened together with the bottom portion in the direction of the wringing aid, and the contents of the chambers are easily wrung out.

According to a further preferred embodiment of the present invention, the label has at least one absorbent pad. Preferably, in a two-piece label, this pad is provided on the bag-away portion so that it can already be detached from the other portion of the label and slid along the thread towards the spout with the label hung over the spout until the pad on the spout is applied. Accordingly, a drop running down the bottom of the spout hits the pillow exactly and is absorbed here instead of dripping off the pot. The training with a label with cushions allows accordingly a drip-free pouring the infused liquid from a pot.

The two closed chambers can be glued together, welded or connected to each other via a metallic clamp. Any conceivable manner of fastening the opposing webs of the shell-shaped material in the region of the upper side of the chambers is conceivable. It is preferable, however, with regard to a possible perforation-free treatment of the shell material, the mutually opposite, each closed upper ends of the chamber by a cross-over these fuse strips to connect with each other. The securing strip is preferably dimensioned such that it rests on the outside of the chambers in the region of its upper side and this presses against each other. The security strip can be made of plastic, sheet metal or of a cardboard material. In a metal strip, the attachment of the same can be done on the shell material by stapling. The securing strip preferably has at least one passage opening for the passage of the thread. Preferably, in the central region of the securing strip, a passage opening can be provided which is dimensioned sufficiently to guide the thread secured to the bottom section with its opposite ends at a relatively large distance from the infusion bag on the top side.

When wringing the infusion bag of at least one thread between the two chambers is pulled out of the dual-chamber bag. Here, the bottom portion against which the thread is secured, taken and guided in the direction of the top of the chambers, that is pulled out through the insertion opening from the dual-chamber bag. Here, the bottom portion is taken along with the lower end of the thread and guided in the direction of the top of the chambers, ie to the upper end of the double-chamber bag. Since the thread is not received within the chambers, but is at least between the top and the bottom portion outside the chambers, their movement is not predetermined when wringing the infusion bag by the tensioned when wringing thread. The chambers can therefore lay, for example, in one or more folds, including their chamber walls, and press out the substance received in the chambers as best as possible. The Auswringverhalten is then improved over the previously known solution proposals. As an abutment for the tensile force of the thread For example, a spoon can be placed against the top in the region of the introduction opening, which represents an easy handling of the infusion bag according to the invention.

With a view to the best possible wringing of the bottom section as well, it is proposed according to a preferred development of the present invention to provide the at least one thread on the outside of the bottom section. When wringing the infusion bag is then compressed not only the double-chamber bag with its two chambers, but also in the folded state usually V-shaped bottom fold, which also contains substance which should be wrung when removing the infusion bag from the Aufgießflüssigkeit to a drip-free as possible To allow removal of the infusion bag. For this purpose, the thread may be formed as a loop, in such a way that the loop base surrounds the bottom portion. The loop bottom may completely surround the bottom portion outside of the dual chamber bag. Thus, the loop bottom can envelop the bottom section. By this is meant, for example, a configuration in which the loop bottom circumferentially surrounds the lower part of the two chambers, including the bottom section, i. around the bottom of the Hüllstoffs is led around. With regard to a predetermined wringing behavior, it is preferable to position-secure the loop bottom in the region of the bottom section relative to the chambers. A corresponding position assurance can be formed, for example, in that the thread in the bottom section is directly connected to the wrapping material. In this embodiment can be dispensed with a loop-shaped design of the thread. Rather, on the outer sides of the wrapping material outside guided yarns can be attached directly to the shell material at its lower end and fixed here.

A preferred embodiment is one in which the loop base extends between the two chambers, ie the loop is initially guided parallel to an outer side of a chamber, deflected substantially at right angles in the bottom section, and redirected substantially at right angles behind the bottom section and guided upward. The loop bottom can in this embodiment by a seam or a Adhesive against the bottom section to be secured in position.

In an alternative way of securing the position of the loop bottom in the region of the bottom section, the loop bottom is arranged between the two chambers, preferably in the bottom of the bottom fold extending between the chambers. The thread is inserted in this preferred development in the bottom of the Bodenfalz, ie is located relative to the outer lower edge of the enveloping material in the direction of the top inwardly displaced. Since the infusion bag is handled regularly on the label and the thread is guided tightly in the insertion openings and thus held in the absence of traction in position, sufficient training is sufficient to ensure the loop bottom in the usually V-shaped Bodenfalz. The arrangement of the loop bottom within the Bodenfalz leads to a symmetrical folding together of the oppositely formed chambers during wringing, which has proven to be advantageous in terms of a preferred Auswringverhalten. It has been shown that in such an embodiment, the two chambers of an orientation substantially parallel to each other symmetrically bend C-shaped. In this case, the swollen substance forms a core around which the sheath material is placed under tension on the outside of the respective chambers. With this movement of the bottom portion to an upper point where the opposed chambers are connected to each other at the top, the infusion bag can be effectively wrung out.

In an alternative embodiment, in which preferably is dispensed with a loop, only a thread is provided, whose bottom end is connected to a traction means which engages in the Bodenfalz. As a traction means is understood in particular a means which is formed of a material other than the thread and the wrapping material and which introduces the tensile force applied by the thread at least linearly in the bottom portion, preferably over the entire width of the chamber. Such a traction means may be formed for example by a relatively stiff tendon made of plastic or wood.

With a view to the simplest possible fixation of the infusion bag to a jug or cup is proposed according to a preferred embodiment of the present invention, to open the loop at two different locations in the label and lead out at two spaced inlet openings at the top of the shell material. After tensioning the parallel threads, for example, the spout of a pot or the handle of a cup can be introduced into the free space formed between the two thread strands. In such an embodiment, the end provided on the two threads label abuts against the spout or handle and prevents so that the label is inadvertently drawn into the vessel, which in particular when pouring the infusion bag, ie when pouring infusion liquid into the vessel is afraid.

The Figures 1 and 2 show a first embodiment of an infusion bag 1, which comprises a double-chamber bag 2, a label 3 and a extending between the label 3 and the dual-chamber bag 2 thread 4 with two mutually parallel thread strands 4a, 4b.

The double-chamber bag 2 is formed by a tubular substantially V-shaped enveloping enveloping material, which is placed on the upper side 6 of the double-chamber bag 2 in folds 7 to close the wrapping material 8 end. At its opposite bottom, the double-chamber bag 2 has a bottom portion 8 of the wrapping material 5, which is formed into a bottom fold 9 and which interconnected by the tubular shell material, opposing chambers 10 of the dual-chamber bag 2 together. The bottom fold 9 is presently formed inwardly, i. a base 11 of the bottom rebate 9 is located between the two chambers 10 and within an interior space 12 which is enclosed by the circumferential tubular casing material 5. The chambers 10 terminate in the region of the bottom at about the same height in the shape of a lobes 14 of the bottom portion 8, in which the outer edge of the bottom fold 9 opens.

The label 3 is presently designed as a two-part label with a bag-near section 3a and another, bag-distant section 3b. Between both sections 3a, 3b is the material of the label, for example a cardboard, starting from the Long sides of the label 3 inwardly cut to form a slot 15. Between the opposite ends of the slots 15, the two label sections 3a, 3b are connected by a film hinge 16 with each other. In the Figures 1 and 2 the label 3 is shown in the unfolded state. Usually, the infusion bag 2 shown is manufactured and packaged with a label 3, the side surfaces of which lie on one another.

The in the top view FIG. 1 shown label surfaces 17 thereby form the outer surface of the label in the original state and can be designed in a conventional manner, in particular printed and provided with the brand of the manufacturer and indicate the variety of substances contained in the infusion bag 1 to be leached. The other section 3b points to his, based on the illustration after FIG. 1 rear bottom, an adhesive strip 18, which is glued with the interposition of the free ends of the thread strands 4a, 4b on the back 19 of the label portion 3a. On the free upper side of the adhesive strip 18, an absorbent pad 20 is preferably applied from a tamponade. In particular, flowable materials are preferred, such as are used, for example, in kitchen utensils or sanitary napkins. The cushion should preferably be formed as flat as possible, so that the opposite back sides 19 of the label sections 3a, 3b can be placed against each other in parallel with the pad 20 interposed. The size of the pad 20, in particular the thickness of the pad 20 should be selected so that the pad 20 can fulfill the desired, and explained in more detail below function.

This adhesive strip 18 is, in particular, a paper or cardboard strip which is glued to the rear side 19 of the label section 3 b.

The bag-near label portion 3a has two in the extension direction of the thread strands 4a, 4b arranged approximately at the same height through openings 21 which are spaced transversely to the longitudinal extent of the thread strands 4a, 4b, but otherwise provided in the central region of the square label portion 3a. The passage openings 21 are dimensioned so that the thread 4 can be pulled through the passage openings 21.

In the present case, the thread 4 is a loop-shaped, one-part thread strand, the two ends of which are connected by the adhesive strips 18 to the label section 3b. From this label section 3b, the thread strands 4a, 4b are substantially parallel to each other, lie in the region of the inner end of the respective slots 15 and between the two sections 3a, 3b from the back 19 of the label 3 to the other side of the label, ie the in FIG. 1 shown label surface 17 of the bag-near label portion 3a out. On this label surface 17, the thread strands 4a, 4b extend to the through openings 21, through which the thread strands 4a, 4b are led to the back 19 of the bag-near label section 3a. The thread strands 4a, 4b are attached to the label 3 only via the adhesive strip 18 and positionally positioned due to the passage openings 21 and the slots 15; there, however, not connected to the label.

Between the label 3 and the dual-chamber bag 2, the thread strands 4a, 4b extend as a free longitudinal section 4c and enter between the closed chambers 10 each in the interior 12 a. The lateral spacing of the thread strands at this passage point 22 corresponds approximately to the lateral spacing of the passage openings 21. The arrangement of the thread 4 in the region of the double-chamber bag 2 is substantially trapezoidal. From a passage point 22, the thread runs in the direction of the bottom and to the outer longitudinal side of the double-chamber bag obliquely downward to emerge approximately at the interface of Bodenfalz 9 with this outer longitudinal side of the interior 12 and led to the outer edges of Bodenfalz 9 become. At these outer edges, the two yarn strands 4a, 4b are deflected in a direction parallel to the bottom of the double-chamber bag. More precisely, the thread strands 4a, 4b are inserted into the bottom fold 9 and form there a loop bottom 4d of the thread 4, which preferably rests at least linearly in the base 11 of the bottom fold 9.

In the in the Figures 1 and 2 shown untwisted alignment of the thread strands 4a, 4b form the lengths 4c of the corresponding strands 4a, 4b between them a free space 23. The length of the thread 4 is chosen so that this space can be performed with a hanging in a pot or a cup infusion bag 1 on the spout or the handle of a cup. This allows the label 3 of the infusion bag are securely held on the outside of the container.

In the embodiment shown here, however, in particular when hanging in a pot, the film hinge 16 is broken or torn by twisting the two label sections 3a, 3b and the bag near section 3a in the direction of the double-chamber bag 3 and along the thread strands 4a, 4b shifted. The other label portion 3b is positioned relative to the spout such that the pad 20 abuts adjacent the spout outer surface. This system is secured by tensioning the thread strands 4 a, 4 b, which extend on both sides between the label section 3 a and the other label section 3 b and surround the spout on the outside. For clamping the bag-near label portion 3a is placed on the other label portion 3b opposite side of the spout. By appropriate dimensioning of the passage openings 21 with respect to the thickness of the thread 4, a frictional connection between the thread 4 and the other label portion 3b can be generated, which in any case is sufficient to press the pad 20 together with the other label portion 3b against the spout. When pouring at the bottom of the spout along running drops thus hit the cushion 20 and are absorbed by this. The dimensioning of the pad accordingly has to be done in such a way that the amount of drops to be expected in the case of repeated dispensing of the infused liquid can be absorbed by the pad 20.

After leaching the substance contained in the chambers 10, for example tea, the label 3 is released from the spout. The user holds the other label portion 3b with his one hand and moves with his other hand the bag-near label portion 3a in the direction of the bag 2. The bag-near label portion 3a comes first to rest against the double-chamber bag 2. With progressive relative spacing of label portion 3a and label portion 3b, the loop bottom 4d is raised toward the label portion 3a. More specifically, the loop bottom 4d is centrally guided and raised together with the Bodenfalz 9 in the inner space 12. The two opposing chambers 10 follow with their lopsided end pieces 14 of this movement. The outside of the chambers 10 is in this case convex, substantially C-shaped arc and clamped, whereby an optimal wringing of the residual liquid is ensured from the chambers until the Bodenfalz 9 at the top 6 at the upper boundary of the interior 12 comes to rest. The hitherto hanging over the vessel double chamber bag 2 can then be disposed of without a dripping of residual liquid from the dual-chamber bag 2 is to be feared.

In the embodiment of the Figures 1 and 2 The discussed embodiment can be sealed in a manner known per se in an envelope forming an outer packaging, which can just as well form the other section of the label 3, ie can serve in particular for fastening the free ends of the thread strands 4a, 4b.

Alternative embodiments to those in the Figures 1 and 2 Embodiments shown are in the FIGS. 3 and 4 shown. Same components are in relation to FIG. 1 marked with the same reference numerals.

That in the FIGS. 3 and 4 Accordingly, the thread 4 is not formed as a loop with a loop bottom, but extends as a single-strand thread piece between the other label portion 3b and the bottom portion 8 of the double-chamber bag 2. In the region of the double-chamber bag 2 is the thread 4 also through the interior 12, ie out of the chambers 2. In the present case, the thread 4 is passed through a recess 24 recessed in the region of the bottom fold 9 and connected there to a rod-shaped traction means 25, for example an elongated wooden rod in the width of the double-chamber bag 2. When wringing the traction means 25 transmits the tensile force of the yarn 4 substantially over the entire width of the bottom portion of the chambers 10, which are thereby arcuate in the manner already described above C-shaped. The rod-shaped traction means 25 is also in the in the FIGS. 3 and 4 shown Ausführurigsbeispiel in the base 11 of the bottom rebate 9, that extends parallel to the plane 12 containing the interior space or parallel to the substantially flat chambers 10th

In FIG. 5 is an enlarged plan view of the head of the dual-chamber bag 1 along the line VV as shown in FIG Fig. 1 shown. This illustration illustrates the fixation of the juxtaposed, on the upper side each closed for themselves Chambers 10 by a securing means 26, which in the present case is formed by a cardboard strip. This cardboard strip is trapezoidal in side view, so that the outer contour of the contour of the head portion of the teabag 2 corresponds (see. FIG. 1 ). The securing means 26 is woven through the shell material of the chambers in the case of chambers 10 lying on top of one another. The free ends 26a of the securing means are then exposed on one side to the dual-chamber bag 2, while the middle piece 26b is exposed on the opposite side. The securing means 26 extends substantially in a straight line. By passing the securing means 26 through the wrapping material 5, this has laid in waves around the securing means 26. In the region of the center piece 26b of the thread 4 is enclosed with its two strands 4a, 4b and thus laterally fixed (see. Fig. 5 ).

After in the Figures 6a-6g The sequence shown here is first the shell material 5 shown here without tea leaves starting from the in Fig. 6a shown initial state first folded once each end, so that the corners are folded approximately to the central longitudinal axis L. The resulting mean peak 27 is placed in a subsequent folding step on the already double lying folded end. Thereafter, the tubular shell material 5 is closed on both sides. Thereafter, the bottom fold 9 is formed in the middle of the wrapping material (cf. Fig. 6d ).

Thereafter, the thread 4 is inserted into the bottom fold 9 and placed on the inside of a chamber 10. The other chamber 10 is now placed by pivoting the enveloping material 5 by 180 ° to the underlying chamber. In any case, the top 6 of the two previously closed by folding chambers 10 is now placed against each other, including the thread 4. Now, the in Fig. 6f achieved situation. This in Fig. 6f Next to the dual-chamber bag 2 marked securing means 26 is now woven through the head of the double-chamber bag 2, so that the head ends of the bag are fixed against each other, so that the closure caused by folding of the individual chambers 10 is secured.

When wringing the thread 4 runs between the two head portions of the chambers, ie between the two upper sides 6 of the chambers 10 in the region of the center piece 26b of the securing means 26 therethrough. The thread 4 is sufficiently freely movable for wringing, but fixed in a direction transverse to the thread extension through the securing means 26 woven through it (cf. Fig. 5 ).
