. WO 2011/147591 PCT/EP2011/002661 i Portion capsule for producing a beverage
The present invention relates to a portion capsule for producing a beverage, said portion capsule having a cavity in which a raw beverage material is provided, wherein, in order to produce the beverage, an opening is introducible into the portion capsule.
Such portion capsules are well known from the prior art and are available on the market for example as coffee portion capsules. In these coffee portion capsules, the cavity is filled at least partially with coffee powder and hot water flows through said cavity to produce a coffee, espresso and the like. In order to prevent the coffee located in the cavity from losing its aroma, the portion capsule is preferably hermetically sealed.
Therefore, in order to produce the coffee, openings have to be able to be introduced into the portion capsule or already be present therein in advance.
In particular in the case of coffee portion capsules, there 1s a permanent desire on the part of a person skilled in the art to improve the quality of the resulting coffee beverage. A large role is played here, inter alia, by the displacement of the air which is located for example in the cavity in the portion capsule but also in the coffee powder, and also the residence time of the hot water in the portion capsule.
Therefore, it was the object of the present invention to provide a portion capsule with which a good coffee beverage is producible.
The object is achieved by a portion capsule for producing a beverage, said portion capsule having a cavity in which a raw beverage material is provided, wherein, in order to produce the beverage, an opening

The statements made with respect to this subject of the present invention apply in equal measure to the other subjects of the present invention, and the features disclosed here can be combined with other subjects of the present invention and vice versa.
According to a preferred or a further subject of the present invention, flow takes place through the portion capsule in an asymmetrical manner at least in sections and at least temporarily with respect to at least one plane of symmetry of the unopened portion capsule.
The statements made with respect to this subject of the present invention apply in equal measure to the other subjects of the present invention and vice versa, and the features disclosed here can be combined with other subjects of the present invention and vice versa.
Preferably, the capsule is provided in a horizontal
. WO 2011/147591 - 8 - PCT/EP2011/002661 ; manner while flow takes place therethrough, i.e. its central axis extends horizontally. The plane of symmetry mentioned above or hereinbelow is preferably a plane of symmetry which extends at least substantially along the horizontal.
A further or a preferred subject of the present invention is a method in which, while the liquid flows in, the cavity in the portion capsule is vented at least temporarily via at least one opening. This opening can be located in the membrane or in the base of the portion capsule. Preferably, the venting takes place at least temporarily through both openings.
Preferably, the venting takes place wvia one or more opening(s} which are not used for the liquid inlet or liquid outlet.
The invention is explained in the following text with reference to figures 1-7. These explanations are only by way of example and do not limit the general concept of the invention. These explanations apply in equal measure to all subjects of the present invention.
Figures 1-7 each show an embodiment of the portion capsule according to the invention or of the method according to the invention in two views in each case.
Figure 1 shows a first embodiment of the portion capsule 1 according to the invention. Said portion capsule has a basic element 2 which in the present case is frustoconical. This basic element has a cavity 13 which is filled at least partially with a raw beverage material which, for example, is extracted and/or dissolved. In the present case, the raw beverage material is coffee powder which is extracted with hot water and is used to produce for example a coffee or an espresso. Once the raw beverage material has been introduced into the cavity, the latter is closed
. WO 2011/147591 - 9 - PCT/EP2011/002661 . preferably with a membrane, in that the membrane is sealed or adhesively bonded to the basic element.
According to the invention, the portion capsule has a first plane 5 which extends in the axial direction of the portion capsule. In the present case, this is a horizontal plane 5 which in the present case is also at the same time a plane of symmetry, in particular a plane of mirror symmetry, of the unopened capsule.
According to the invention, it is provided that, for producing for example a beverage, the portion capsule has an opening 4, which 1s in particular only introduced when the portion capsule 1 is located in the respective coffee machine. The opening 4 is provided at a distance from the plane of symmetry 5. As can be seen in particular from the right-hand illustration in figure 1, the opening 4 is two openings in the membrane, which are each also provided at a distance trom a vertical plane of mirror symmetry 6 of the unopened capsule but in a mirror-gsymmetrical manner with respect to the plane of symmetry 6. As can furthermore be seen from the right-hand illustration in figure 1, both openings 4 in the membrane are distributed in an asymmetrical manner in the membrane 3 with respect to a first plane of symmetry 5, that extends in the axial direction, of the unopened capsule, i.e. both openings are located in the lower part of the portion capsule with respect to the horizontal plane of symmetry 5, while the upper part remains unopened. As can be seen in particular in the left-hand part of figure 1, in order to produce a beverage, the capsule also has to have in its base a further opening 9, which in the present case is arranged centrally but can also be provided at a distance from one of the planes 5 or 6. This opening is required in particular for the outlet of the produced beverage. The portion capsule is preferably processed as illustrated in a coffee machine, i.e. its central axis is provided horizontally while flow takes place
. WO 2011/147591 - 10 - PCT/EP2011/002661 ; through the portion capsule.
Figure 2 shows substantially the embodiment of the capsule according to figure 1, wherein in the present case an insert member 7 is provided in the vicinity of the base. This insert member is preferably a screen or a nonwoven, which is intended in particular to prevent parts of the raw beverage material, for example coffee powder, from passing into the beverage to be consumed.
Preferably, the member 7 is a nonwoven which is particularly preferably sealed to the base of the portion capsule. This nonwoven can be pierced when the portion capsule is opened at the base.
Figure 3 shows substantially the embodiment according to figure 2, wherein in this case the capsule has a further insert member, which is provided in the vicinity of the membrane 3 of the portion capsule. This member can be for example a liquid distributor or a raw beverage material retention member.
Figure 4 shows a further embodiment of the present invention. Reference can be made essentially to the embodiment according to figures 1-3. However, in the present case, there 1s additionally illustrated a liquid supply means 10, by way of which liquid is supplied in the direction of the portion capsule. In the present case, this liquid is hot water which, as illustrated by the arrow, is supplied at a distance from the plane of symmetry 5 of the portion capsule. In the present case, the liquid is supplied centrally between the two openings 4 in the membrane 3 and then flows through the openings 4 into the capsule. There, the coffee powder is extracted and the prepared beverage leaves the portion capsule through the opening 9. The illustrated arrows are intended to symbolize the possible flow pattern in the portion capsule. It can clearly be seen that this is for example asymmetrical
. WO 2011/147591 - 11 - PCT/EP2011/002661 - with respect to the plane of symmetry 5. The present embodiment has the advantage that air which is located in front of and/or within the capsule is pushed out of the capsule uniformly and along a predictable path.
Alternatively or additionally, the minimum residence time of the liquid in the capsule is longer than in the case of a capsule of which the membrane is opened centrally and/or symmetrically.
Figure 5 shows substantially the embodiment according to figure 4, wherein the capsule in the present case again has an insert member 7, in this case a screen or a nonwoven.
Figure 6 shows yet another embodiment which is based on the embodiment according to figures 4 and 5. In the present case, the portion capsule has a further insert member 8, for example a membrane or the like, which can serve as a distribution member, but which can also be destroyed by the supply of the liguid or by the pressure built up and as a result liquid can flow in the cavity, located behind the membrane 8, in the portion capsule 1.
Figure 7 shows a further embodiment of the present invention, wherein reference can be made essentially to the embodiments in figures 1-6. As can be seen in particular from the right-hand illustration in figure 7, four openings 4, 14 are provided in the membrane 3.
Two of these openings 4 are provided for the liquid inlet and two openings 14 are provided as venting openings, out of which for example air or other gases which are located in the portion capsule can escape at least temporarily from the portion capsule when the portion capsule is pierced and/or when the liguid runs in. The openings 14 are in this case arranged above the openings 4 with respect to the gravitational field of the Earth. Venting is symbolized by the arrow 15. In
: WO 2011/147591 - 12 - PCT/EP2011/002661 - the present case, the openings 14 are arranged on the plane of symmetry 5 and are provided in a symmetrical manner with respect to the plane of symmetry 6. The openings 4 for the liquid inlet are in the present case arranged in a vertical plane one above another and in an agymmetrical manner with respect to the plane of symmetry 5 of the unopened portion capsule, wherein in the present case the liquid inlet means 10 ig arranged in the same vertical plane 6 as the two openings 4 but between the two openings 4. Once the gas has escaped from the portion capsule, the openings 14 can also act as liquid inlet openings.
It can be seen from the left- hand illustration in figure 7 that the portion capsule 1 can alternatively or additionally have in its base a venting opening 16, which is preferably introduced into the portion capsule by the coffee machine.
This venting opening 16 is provided in addition to the outlet opening 9 and serves to dissipate gas which is located in the portion capsule prior to piercing.
With respect to the gravitational field of the Earth, the opening 16 is located above the opening 9. The opening 9 is preferably arranged above the openings 14 with respect to the gravitational field of the Earth.
