infusion unit

The invention relates to a brewing unit with a brewing part containing a filling material, preferably tea leaves, and a handle connected to the bag part.

Such infusion units are z. B. known in the form of conventional teabags. In the case of conventional tea bags, micronized tea material is contained in a bag part. The bag part is completely closed, and on a top thereof is attached via a drawstring a paper or Papierfähnchen as a handle. Such tea bags are often used for the portionwise as well as the wise preparation of tea. Usually, such tea bags are loaded in a capacity of 3, 5 to 5, 0 g, this amount is designed to prepare a cup of tea with this tea bag. If such a tea bag j edoch for preparation bspw. of a cup of tea (compared to a cup containing about 150 ml, a cup holds 200 to 300 ml), the amount of tea contained in the tea bag is no longer sufficient.

Furthermore, the tea contained in conventional teabags is a fine fraction and usually of high quality from a high quality. distinct leafy tea leaves.

In particular, in the "street sale" a quick preparation of a tea is required, so that here is always used for the preparation of teas bag tea or tea bags.

Because of the above-mentioned disadvantages, however, the tea prepared with such tea bags is not always sufficient to meet the quality requirements of the consumer, so that only small quantities of tea beverages can be sold in street vending.

Here it is an aim of the applicants to create a way to be able to offer high-quality tea drinks in street sales, which come close to the home or in good tea rooms prepared teas or correspond qualitatively. The preparation of the tea should be done quickly, as it is important for street vendors.

In particular, it should be possible to use a brewing unit to be specified with the invention in connection with disposable drinking cups provided with lids.

The indicated goals resp. the object to be seen therein is achieved by an infusion unit according to the invention. Advantageous developments of this Aufgusseinheit are given in the dependent claims 2 to 9.

The infusion unit according to the invention is characterized in that a plate-shaped element, preferably made of paper, cardboard or plastic, is attached directly to the bag part as a handle. The bag part is attached to the handle so that it is arranged in a direction of the longest extent of the handle between opposite ends of the handle so that at 90 ° against each other tilted handle and bag part, the handle on both sides via a connection point extends the handle with the bag part addition. In the latter position, the bag part and the handle therefore together form a "T" shape, wherein the two sections of the crossbar of the "T" need not necessarily be the same length.

The infusion unit according to the invention is particularly suitable for picking up loose, whole tea leaves and thus creating the conditions for the preparation of a high-quality tea. However, the infusion unit according to the invention is not limited to tea as infusion material, it can in principle other infusion materials, such as. Fruit schnitzel or the like can be used. The arrangement according to the invention of the bag part on the handle makes it possible to reliably use the handle as a "stopper" when the bag part is hung in a container for preparation of the infusion beverage by, for example, the two projecting parts of the handle on an opening edge of the Can be stored container or be used in a manner to be explained in more detail with reference to the embodiment in a specially designed for the interaction with the Aufgusseinheit invention lid.

The bag part can be made of a cellulosic material or any other porous material suitable for the preparation of infusion beverages, in particular nylon.

According to an advantageous embodiment (claim 2), the bag part is seen on the handle in its longest extension defined off-center between the opposite ends. In a further variant (claim 3), such an arrangement is preferred, which divides the handle in its longest extent in a ratio of about 1 to 3. This type of arrangement of the bag part on the handle is in particular with the preferred provided connection of the infusion unit in connection with a specially designed lid for a disposable cup of advantage. Another advantageous embodiment in this context is specified in claim 4. Thereafter, the handle has a substantially rectangular basic shape, wherein the more remote from the junction of the handle with the bag part end of the handle is rounded. This rounding of the end of the handle facilitates insertion of the same into a receiving slot or makes it possible to deposit this end on a correspondingly contoured storage surface for fixing the infusion unit in a "brewing position".

A brewing unit as defined in claim 5, wherein the bag portion of a handle is defined by crimping one end of the handle and adhering one end of the bag portion between two surfaces of the handle lying on each other by crimping, resulting in a particularly simple and stable construction of the brewing unit according to the invention , in particular the connection point between the handle and the bag part. Instead of gluing the end of the bag part in the fold of the handle can be set in other ways, for example. By sewing.

In a further development (claim 6), it is provided that the folded-over section of the handle forms a grip section for detecting the infusion unit. By crimping this end is doubled and additionally stabilized so that it forms a more stable grip portion than the other end of the handle.

Preferably, the handle is wider in a width measured transversely to the direction of the longest extension than the bag part attached to it and protrudes in this direction on both sides over the bag part. This specified in claim 7 advantageous development allows a support of the handle on a support or a guide surface in the area in which the bag part is located. Advantageously, the bag unit is a flat bag (claim 8). This flat bag is preferably in its longer extension Arranged transversely to the longest extent of the handle and fixed in this orientation to the handle.

Preferred dimensions of the infusion unit are specified in claim 9. Thereafter, the bag unit has a length of approx. 100 mm - 130 mm and a width of approx. 50 mm up. The handle has a length of approx. 80 mm and a width of approx. 54 mm, wherein the first end protruding beyond the connection point of the bag part with the grip part is approx. 20 mm and the second protruding end approx. 60 mm long.

In a further advantageous embodiment of the invention (claim 10) is finally provided that a fold extends in the direction of the longest extent of the handle approximately centrally over the latter over the entire length. This fold has the advantage that the brewing unit according to the invention, for example. can be used to brew an infusion beverage in a cup, without that threatening to completely slip into this during the pouring of the Aufgusseinheit arranged in the cup. For this purpose, the handle of the Aufgusseinheit is slightly compressed along the fold, so that they deviating from the flat, planar shape receives a cross-sectionally approximately triangular shape. Then the handle is hung with its longer section over the edge of the cup. Due to the angled shape, the handle adapts better to the round outside of the cup and can not slip so easily.

Further advantages and features of the invention will become apparent from the following description of an embodiment with reference to the accompanying figures. In the figures show:

In the figures, which illustrate the described embodiment in each case schematically, the same elements are provided with the same reference numerals. The illustrations in the figures are for the invention as limiting as the following description of the embodiment, the limits of the invention are exclusively drawn by the claims. The following description of the embodiments is merely illustrative and improved in understanding of the invention.

In the figures, an infusion unit according to the invention is generally designated by 20 resp. 120 denotes. The infusion unit is generally composed of a handle 22 or 122 and a bag part 21 in the form of a flat bag fastened directly to the handle. The bag part 21 is filled with an infusion material, preferably with loose tea leaves. The bag part 21 is made of a nylon material. The baggage Telteil 21 is prepared by separating a portion of a tubular endless belt and closing one side of the bag part 21 with a sealing seam 28, filling with the infusion material and closing the opposite end of the bag part 21 with a further closing seam 29. The points in the middle section of the bag part 21 indicate that the nylon material is porous in order to prevent it from penetrating with a pour-on liquid, for example. to allow hot water. In this way it is ensured that the infusion material in contact with the infusion liquid and can act on these for the preparation of an infusion beverage.

The handle 22 or 122 is made of a flat material, in particular of a thin cardboard.

In Fig. 4, a blank for a first embodiment of the handle 22 is shown. There it can be seen that a fold designated 25 extends transversely to the handle 22, wherein on both sides of the fold 25 j in each case grooves 26 and 27 are provided. To connect the handle 22 to the bag part 21, adhesive is applied to an upper side of the blank for the handle 22 in the areas between the fold 25 and the grooves 26 and 27. Then, the bag part 21 is applied with a transverse edge at one of its ends to the fold 25 and the blank folded over along the fold 25 and transferred to the bag part 21. In this way, the bag part 21 is glued to the handle 22.

In Fig. 8, an alternative embodiment of a handle 122 is shown. This also has a transverse to the handle 122 extending fold 125. In this embodiment, the grooves 26 and 27 of FIG. 4 illustrated corresponding grooves. Instead, there is a fold 128 extending longitudinally of the handle 122 (i.e., in the direction of its longer extent). This fold runs perpendicular to the first fold 125 and is over the width of the handle 122 seen approximately in the middle. The fold 128 is also in the figures 6 and 7, in which a with the in FIG. Shown handle 122 provided embodiment (Aufgusseinheit 120) is shown. The fold 128 serves to provide improved retention of the infusion unit of the invention when used to brew an infusion beverage in a cup or similar container. Namely, the handle 122 may be kinked and "angled" along the fold 128. In this position, it better conforms to the outer shape of a cup or similar container and, when hung over the cup rim to hold the bag portion 21, not to slip into the cup or other brewing vessel when the contents of bag portion 21 are infused with a brewing liquid.

The connection of the booting part 21 with the handle 122 works analogously as previously described in connection with the embodiment shown in Figures 1, 2 and 4. Again, by folding one end of the handle 122 along the fold 125, an overlapping area is created, in which the bag part 21 is glued to one end.

As in particular in FIG. 1 and 2 resp. 6 and 7 can be seen, the handle 22 and. 122 wider than the bag part 21, wherein the bag part 21 in the center of the handle 22 and. 122 is arranged, so that on both sides of the bag part 21, an approximately equally wide edge of the handle 22 and. 122 survives. As a result of this arrangement, when the bag part 21 is connected to the handle 22 or 122 at least in the projecting region of the handle 22 or. 122 a direct bonding of the two superimposed surfaces of the handle 22 and 122 reached, which means an additional strength of this attachment.

After connecting as described above between bag part 21 and handle 22 and. 122 forms the handle 22 and. 122 for two j side of the junction between the handle 22 and. 122 and the bag part 21, protruding portions, a shorter handle portion 23 and 123, on which the cardboard material of the handle 22 and. 122 through the ümfalzen along the fold 25 and. 125 is double, and a support portion 24 and 124, respectively. The support portion 24 resp. 124 has a rounded end, which will be discussed below the background of this rounding.

The bag part 21 is seated in the handle 22 or. 122 not centered, d. H . Section 23 resp. 123 and the support section 24 and. 124 are unevenly long. In the exemplary embodiments, the handle portion 23 and / or. 123 measured to the junction with the bag part 21 has a length of about 20 mm and the support portion 24 and. 124 has a correspondingly measured length of about 60 mm. Thus, the joint between the bag part 21 and the handle 22 or 122 divides the latter in a ratio of about 1 to 3. The bag part 21 in the embodiment shown has a width of about 50 mm, the handle 22 has a width of about 54 mm. In this case, the projection of the handle 22 seen in the transverse direction to the right and left of the bag part in each case about 2 mm. The bag part has a length of about 110 mm.

In the Figs. 5a to 5c show a preferred use of the infusion unit according to the invention in connection with a lid 1 for a disposable drinking cup.

The cover 1 has a bottom plate 2 facing the drinking cup in the application case and a cover 3 arranged above the bottom plate 2. Between this bottom plate 2 and the cover 3 and a peripheral side wall 4, a receiving space 5 is formed. In the bottom plate 2, a substantially rectangular opening 6 is provided approximately in the middle, in the cover 3 and. between the cover 3 and the edge of the lid 1, a slot-shaped opening 7 is provided in the region near the edge. This slot-shaped opening 7 is covered by a tab 13 of the cover 3. In the slot-shaped opening 7 opposite region, the bottom plate 2 forms a support 10th The inventive infusion unit 20 or. 120 is particularly adapted to be used with this lid 1 together to allow a preparation of a relatively high-quality infusion beverage, in particular a tea, in the fast street sale. For this purpose, first the infusion unit 20 according to the invention or. Threaded 120 in the lid 1. This is shown in FIGS. 5a and 5b. With the handle portion 23 and. 123 ahead, the brewing unit according to the invention is guided through the opening 6 in the bottom plate 2 of the lid 1, so that the handle portion 3 passes through the slot-shaped opening 7 therethrough. Now, the handle portion 23 or 123 and thus the handle 22 and 122 so far pulled through the slot-shaped opening 7 until the support portion 24 and. 124 through the opening 6 in the receiving space 5 of the lid 1 can be obtained. Then the handle 22 or. 122 tilted and pushed back into the receiving space until the support portion 24 and 124 of the handle 22 and 122 rests on the support 10. Since the cover 1 is designed to be circular overall and thus the support 10 also has a part-circular outer contour, the support section 24 is or. 124 as described above provided with a rounded outer edge.

In the in Fig. 5b illustrated position, the infusion unit 20 according to the invention or. 120 protrude when placing the lid 1 or the unit formed from the lid 1 and Aufgusseinheit 20 or 120 on a filled with a liquid infusion cup in the infusion liquid and act to prepare an infusion beverage.

After a defined contact time, the bag part 21 of the infusion unit 20 or 120 must be removed from the infusion liquid. This can be achieved in the combination of the infusion unit 20 according to the invention or. 120 done with the lid 1 as shown in Fig. 5c. After the end of the contact time, the grip section 23 or. 123 of the handle 22 resp. 122 and pulled in the direction of the arrow shown in Fig. 5c. As a result, the bag part 21 is made of the infusion liquid and pulled through the opening 6 in the receiving space 5. In this case, the bag part 21 by pressure between the base plate 2 and the support portion 24 and. 124 of the handle 22 or. 122 is pressed together and "wrung out." If the grip section 23 or 123 or the handle 22 or 122 is pulled out of the slot-shaped opening 7 to the maximum, the bag part 21 of the infusion unit 20 or 120 according to the invention is almost completely accommodated in the receiving space 5, j To the extent that it is no longer in contact with the infusion liquid in the drinking cup, a further action of the bag part or of the infusion material in the bag part on the infusion liquid is avoided, thus avoiding tea in the bag part 21. that the tea beverage prepared in the drinking cup becomes overly bitter due to too long pulling.

The infusion unit according to the invention is not limited in its application to the interaction with the lid 1 described in FIGS. 5a to 5c; it can also be used without such a special lid for the preparation of infusion beverages in drinking vessels. For this purpose, in particular the variant shown in Figures 6 to 8 is suitable.
