Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von Aufgußgetränken, bestehend aus einem Beutel aus Filtermaterial zur Aufnahme von für das jeweilige Getränk spezifischen Partikeln, der aus in Streifenform vorliegendem Filtermaterial hergestellt ist, das unter Bildung eines Bodens und zweier von demselben ausgehender, unterschiedlich langer Seitenbereiche für die Partikel undurchlässig verschweißt ist, während der dem Boden gegenüberliegende Bereich zur Bildung einer Öffnung nicht verschweißt ist, und bei dem der längere Seitenbereich vom Boden des Beutels wegweisend einlagig über den kürzeren Seitenbereich und damit über die Öffnung hinausragt (GB-A-549 764).The invention relates to a device for producing infusion beverages, consisting of a bag made of filter material for receiving particles specific to the respective beverage, which is made of filter material in strip form, which forms a bottom and two starting from the same, of different lengths Side areas are welded impermeable to the particles, while the area opposite the bottom is not welded to form an opening, and in which the longer side area points away from the bottom of the bag in a single layer over the shorter side area and thus beyond the opening (GB-A-549 764).

Derartige Vorrichtungen werden beispielsweise zum Herstellen von Tee verwendet, auf den sich - stellvertretend für andere Einsatzmöglichkeiten - die folgenden Ausführungen beziehen. Statt des Wortes "Partikel" wird daher das Wort "Teeblätter" verwendet. Neben dem seit langer Zeit bekannten Tee-Ei sind seit Jahren auch verschlossene Beutel aus Filtermaterial bei der Herstellung von Tee im Einsatz, die eine vorgegebene Menge von Teeblättern enthalten. Es sind auch Filtertüten bekannt, in die nach Aufspannen auf einen Halter Teeblätter eingefüllt werden können.Devices of this type are used, for example, for the production of tea, to which the following statements relate - representative of other possible uses. The word "tea leaves" is therefore used instead of the word "particle". In addition to the tea egg, which has been known for a long time, sealed bags made from filter material have been used for years in the production of tea, which contain a predetermined amount of tea leaves. Filter bags are also known, into which tea leaves can be filled after being clamped onto a holder.

Aus der EP-B-0 020 598 ist eine Vorrichtung bekannt, die lediglich aus einem eine Öffnung aufweisenden Beutel aus Filtermaterial besteht. Der Beutel ist in zwei Abschnitte unterteilt, nämlich in einen Trichter und einen Aufnahmeteil. Die Öffnung dieses Beutels ist am stirnseitigen Ende des Trichters angebracht, das dem Aufnahmeteil abgewandt ist. Zwischen beiden Abschnitten dieses bekannten Beutels befindet sich ein Durchlaß, dessen lichte Weite wesentlich kleiner als die lichte Weite des Aufnahmeteils ist. Das Einfüllen von Teeblättern in diesen Beutel ist schwierig. Die Öffnung des zunächst flachen Beutels ist relativ schlecht auf die zum Einfüllen der Teeblätter erforderliche Größe zu bringen. Ein weiteres Hindernis für die Teeblätter bis hin zum Aufnahmeteil ist der enge Durchlaß, durch den die Teeblätter nicht einfach hindurchtreten können.From EP-B-0 020 598 a device is known which only consists of a bag with an opening There is filter material. The bag is divided into two sections, namely a funnel and a receiving part. The opening of this bag is attached to the front end of the funnel that faces away from the receiving part. There is a passage between the two sections of this known bag, the clear width of which is considerably smaller than the clear width of the receiving part. Filling tea leaves into this bag is difficult. The opening of the initially flat bag is relatively difficult to bring to the size required for filling the tea leaves. Another obstacle for the tea leaves to the receiving part is the narrow passage through which the tea leaves can not easily pass.

Die eingangs erwähnte GB-A-549 764 beschreibt einen Aufgußbeutel aus Filtermaterial, bei welchem der eine Seitenbereich etwas länger als der andere ist. Der dadurch gebildete überstehende Rand dient als Verschluß für die Öffnung des Aufgußbeutels und zur Versiegelung desselben.GB-A-549 764 mentioned at the outset describes an infusion bag made of filter material, in which one side area is somewhat longer than the other. The protruding edge thus formed serves as a closure for opening the infusion bag and for sealing the same.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Vorrichtung sowohl in der Herstellung als auch für die Handhabung einfacher zu gestalten.The invention has for its object to make the device described above simpler both in manufacture and for handling.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß der längere Seitenbereich als einlagige Lasche so weit über den kürzeren Seitenbereich und damit über die Öffnung des Beutels hinausragt, daß die Lasche beim Aufweiten der Öffnung eine in ihrer Längsrichtung gebogene Aufgabefläche zum Aufbringen der Teeblätter bildet und
  • daß die Lasche als Halterung für den Beutel in einem Aufgußgefäß dient.
According to the invention, this object is achieved by
  • that the longer side area as a single-layer tab projects so far beyond the shorter side area and thus beyond the opening of the bag that the tab forms a longitudinally curved feed surface for applying the tea leaves when the opening is widened and
  • that the tab serves as a holder for the bag in an infusion vessel.

Diese Vorrichtung ist einfach gestaltet und einfach zu handhaben. Da die Öffnung sich direkt am Ende des hier nur als Aufnahmeteil für die Teeblätter ausgebildeten Beutels befindet, liegt sie wegen der Lasche nicht an einer Stirnseite, sondern im mittleren Bereich der Vorrichtung. Sie läßt sich daher besonders leicht aufweiten. Zum Einfüllen der Teeblätter in den Beutel wird die einlagige Lasche mit Vorteil ausgenutzt. Sie wird beim Aufweiten der Öffnung des Beutels in ihrer Längsrichtung gebogen und bildet dadurch eine Aufgabefläche. Wenn die Teeblätter auf die gebogene Aufgabefläche aufgebracht werden, wirkt dieselbe bei entsprechender Schrägstellung der Vorrichtung als Rutsche. Die Teeblätter gelangen dadurch quasi zwangsgeführt in den Beutel. Danach dient die Lasche als Halterung für den Beutel, wenn derselbe in eine Teekanne eingebracht wird. Die Lasche kann über den Rand der Teekanne gelegt und auch mittels eines Deckels in der Öffnung der Teekanne eingeklemmt werden. Die Vorrichtung ist insgesamt materialarm, da das Filtermaterial nur im Bereich des Beutels doppelt liegt. Bei der Herstellung der Vorrichtung geht kein Filtermaterial verloren, da kein Trichter ausgeformt wird.This device is simple in design and easy to use. Since the opening is located directly at the end of the bag, which is designed here only as a receiving part for the tea leaves, it does not lie on one end face because of the tab, but in the central region of the device. It can therefore be expanded particularly easily. To fill in the Tea leaves in the bag, the single-layer tab is used to advantage. When the opening of the bag is widened, it is bent in its longitudinal direction and thereby forms a feed surface. If the tea leaves are applied to the curved feed surface, the same acts as a slide when the device is tilted accordingly. As a result, the tea leaves enter the bag in a virtually forced manner. The tab then serves as a holder for the bag when it is placed in a teapot. The tab can be placed over the edge of the teapot and also clamped in the opening of the teapot using a lid. Overall, the device is low in material, since the filter material is only double in the area of the bag. No filter material is lost in the manufacture of the device since no funnel is formed.

In bevorzugter Ausführungsform gehen die beim Verschweißen der beiden Seitenbereiche gebildeten Nähte im Bereich der Öffnung V-förmig auseinander, so daß die Öffnung bei ihrem Aufweiten schräge Ränder erhält. Das Einfüllen der Teeblätter in den Beutel wird dadurch weiter vereinfacht.In a preferred embodiment, the seams formed when the two side regions are welded diverge in a V-shape in the region of the opening, so that the opening receives oblique edges when it is expanded. The filling of the tea leaves in the bag is further simplified.

Weitere vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further advantageous embodiments of the invention emerge from the subclaims.

  • Fig. 2 und 3 zwei unterschiedliche Ansichten der Vorrichtung in vergrößerter Darstellung.
  • Fig. 4 die Vorrichtung in perspektivischer Darstellung.
  • Fig. 5 bis 7 von Fig. 2 abweichende Ausführungsformen der Vorrichtung.
Show it:
  • Fig. 1 shows a schematic representation of a teapot with a device according to the invention arranged therein.
  • 2 and 3 two different views of the device in an enlarged view.
  • Fig. 4 shows the device in perspective.
  • 5 to 7 of Fig. 2 different embodiments of the device.

In einer Teekanne 1 ist eine Vorrichtung 2 angebracht, in der sich Teeblätter befinden. Die in den Fig. 2 bis 7 genauer dargestellte Vorrichtung 2 ragt mit ihrem einen Ende aus der Teekanne 1 heraus. Sie ist durch den Deckel 3 der Teekanne 1 in deren Öffnung eingeklemmt.In a teapot 1 there is a device 2 in which tea leaves are located. The device 2 shown in more detail in FIGS. 2 to 7 protrudes with one end out of the teapot 1. It is clamped through the lid 3 of the teapot 1 in its opening.

Die Vorrichtung 2 besteht aus Filtermaterial, das in Streifenform vorliegt. Sie weist zwei Seitenbereiche 4 und 5 auf, die an ihren Rändern miteinander verschweißt sind. Die durch das Verschweißen gebildeten Nähte 6 sind gestrichelt eingezeichnet. Durch das Verschweißen des Filtermaterials wird ein Beutel 7 gebildet, der einen Boden 8 und die beiden Seitenbereiche 4 und 5 hat. Er weist an der dem Boden 8 gegenüberliegenden Seite eine Öffnung 9 auf, durch welche Teeblätter in den Beutel 7 eingefüllt werden können.The device 2 consists of filter material which is in strip form. It has two side areas 4 and 5 which are welded together at their edges. The seams 6 formed by the welding are shown in dashed lines. By welding the filter material, a bag 7 is formed, which has a bottom 8 and the two side areas 4 and 5. It has an opening 9 on the side opposite the bottom 8 through which tea leaves can be filled into the bag 7.

Der Seitenbereich 4 ist länger als der Seitenbereich 5. Er ragt auf der dem Boden 8 abgewandten Seite über die Öffnung 9 hinaus und bildet eine einlagige Lasche 10. Mit der Lasche 10 kann die Vorrichtung 2 beispielweise in der Teekanne 1 festgeklemmt werden. Sie erleichtert aber auch das Einfüllen von Teeblättern in den Beutel 7, da sie als Rutsche verwendet werden kann. Zum Aufweiten der Öffnung 9 wird der Beutel 7 im Bereich der Öffnung 9 etwas zusammengedrückt. Die Lasche 10 wird dadurch gebogen, und zwar so, daß sie einen in Längsrichtung verlaufende Aufgabefläche bildet. Wenn Teeblätter bei schräg angeordneter Vorrichtung 2 auf die gebogene Lasche 10 aufgebracht werden, rutschen sie zwangsläufig durch die aufgeweitete Öffnung 9 in den Beutel 7.The side area 4 is longer than the side area 5. It protrudes beyond the opening 9 on the side facing away from the base 8 and forms a single-layer tab 10. With the tab 10, the device 2 can be clamped, for example, in the teapot 1. However, it also facilitates the filling of tea leaves into the bag 7, since it can be used as a slide. To widen the opening 9, the bag 7 is compressed somewhat in the region of the opening 9. The tab 10 is thereby bent, in such a way that it forms a longitudinally extending feed surface. If tea leaves are applied to the curved tab 10 with the device 2 arranged obliquely, they inevitably slide through the widened opening 9 into the bag 7.

Die Vorrichtung kann gemäß Fig. 5 insgesamt aus nur einem Streifen hergestellt werden. Dazu wird entweder der kürzere Seitenbereich 5 durch Zurückbiegen bis zur Anlage am Seitenbereich 4 gewonnen und nur in den Randbereichen mit demselben verschweißt oder umgekehrt. Der verschlossene Boden 8 ist durch das Zurückbiegen gebildet.5, the device can be produced from only one strip. For this purpose, either the shorter side area 5 is obtained by bending it back to rest on the side area 4 and only welded to the same in the edge areas, or vice versa. The closed bottom 8 is formed by the bending back.

Erleichtert kann das Einfüllen von Teeblättern in den Beutel 7 noch dann werden, wenn die Nähte 6 im Bereich der Öffnung 9 V-förmig auseinander gehen, so wie es in Fig. 6 dargestellt ist.The filling of tea leaves into the bag 7 can be made even easier if the seams 6 in the area of the opening 9 are V-shaped apart, as shown in FIG. 6.

Entsprechend Fig. 6 und 7 kann am Boden 8 des Beutels eine Falte ausgebildet werden. Dazu werden die Seitenbereiche 4 und 5 über eine kurze Strecke gefaltet und erst dann miteinander verschweißt. Die Höhe der Falte ist in Fig. 6 durch eine strichpunktierte Linie 11 angedeutet. Durch die Falte ergibt sich im Beutel 7 im Bereich des Bodens 8 ein vergrößertes Volumen.6 and 7, a fold can be formed at the bottom 8 of the bag. For this purpose, the side areas 4 and 5 are folded over a short distance and only then welded together. The height of the fold is indicated in FIG. 6 by a dash-dotted line 11. The fold results in an increased volume in the bag 7 in the area of the bottom 8.
