Preferably, the removal of air occurs through one or more holes that are not used for supplying fluid to or draining fluid.

The invention is further illustrated using Fig.1-7. These explanations are only exemplary and do not limit the General idea of the invention. These explanations are equally �you did for all of the objects of this invention.

Fig.1-7 in each case shows the form of the implementation of the portion capsule according to the invention or of the method according to the invention in each case in two forms.

Fig.1 shows a first form of implementation of the portion capsule 1 according to the invention. It has the main element 2, which in this case has the shape of a truncated cone. This basic element has a hollow space 13, which is at least partially filled with a raw material for the preparation of the drink, which, for example, is extracted and/or dissolved. In the case of a raw material to prepare the drink we are talking about finely ground coffee, which is extracted with hot water and prepared coffee or espresso. After the hollow space is filled with the raw material for preparing a beverage, it is preferably closed by a membrane, and the membrane is welded or glued to the main element. Portion capsule according to the invention has a first plane 5, which extends in the axial direction of the portion capsule. In this case we are talking about the horizontal plane 5, which in this case is also the symmetry plane, the first plane mirror symmetry unopened capsules. According to the invention provides that the portion capsule for preparing a beverage has a hole� 4, which primarily occurs when the portion capsule 1 is positioned in the appropriate maker. The opening 4 is located at a distance from the plane 5 of symmetry. How, especially, can be seen on the right image of Fig.1, in the case of hole 1 the two holes in the membrane, which in each case are arranged at a distance relative to the vertical symmetry plane by 6 unopened capsules, but mirror-symmetrically relative to the plane 6 of symmetry. As can further be seen in the right image of Fig.1, both holes 4 in the membrane are distributed asymmetrically in the membrane of about 3 extending in the axial direction of the first plane 5 of symmetry unopened capsules, i.e. both holes relative to the plane 5 of symmetry are in the bottom portion of the capsule, while the upper part remains undiscovered. How, first of all, you can see in the left part of Fig.1, a capsule for preparing a beverage needs in his day to have another hole 9, which in this case is located at the center and which may be located at a distance from one of the planes 5 or 6. This hole, it is first necessary for draining the prepared beverage. Preferably, the portion capsule, as depicted, is processed in the coffee, i.e. its Central axis when the flow of fluid cher�W portion capsule is horizontal.

Fig.2 shows essentially the form of the capsule according to Fig.1, and in this case near the bottom has a built-in element 7. In the case of this built-in element it is preferably of mesh or non-woven material, with which, above all, preventing parts of the raw material for preparing a beverage, for example, finely ground coffee, consumed in a drink. Preferably, the element 7 is non-woven material, which, preferably, is welded to the bottom portion of the capsule. At the opening portion of the capsule at the bottom, this non-woven material may be pierced.

Fig.3 shows essentially the form of implementation according to Fig.2, and the capsule has another built-in element, which is provided near the diaphragm portion 3 of the capsule. In the case of this item it is, for example, the fluid dispenser about the item or the retention of raw materials for the preparation of the drink.

Fig.4 shows the next form of the present invention. First of all, you can refer to the implementation according to Fig.1-3. However, in this case further shows means 10 for supplying the liquid with which the liquid is supplied in the direction of the portion capsule. In this case we are talking about hot water, which is shown by an arrow and is fed to th�research Institute from the plane 5 of symmetry of the portion capsule. In this case, the liquid is fed centrally between the two holes 4 in the membrane 3 and then flows through the holes 4 in the capsule. There finely ground coffee extracted, and ready to drink out of the portion capsule through the opening 9. Arrows indicate possible picture of the flow in the portion capsule. You can clearly see that it is asymmetric relative to the plane 5 of symmetry. This form of implementation has the advantage that the air which is in front of and/or inside the capsule is displaced from the capsule evenly and in a predictable way. Alternative or additionally, the minimum length of stay of the liquid in the capsule is greater than that of the capsule, the membrane which opens in the center and/or symmetrically.

Fig.5 shows essentially the form of implementation according to Fig.4, and the capsule in this case, by contrast, has a built-in element 7, here the mesh or non-woven material.

Fig.6 shows this form of implementation, which is based on the form of implementation according to Fig.4 and Fig.5. In this case, the portion capsule has one built-in element 7, for example a membrane or the like, which can serve as a distribution element, but which also can be destroyed by applying a liquid, for example due to the pressure created�I, and whereby the fluid can flow in behind the membrane hollow space 8 of the portion capsule 1.

Fig.7 shows the next form of the present invention, and reference can be made, but essentially, the implementation according to Fig.1-6. How, first of all, you can see from the right image of Fig.7, the membrane 3 has four openings 4, 14. Two of these holes 4 are provided for intake of liquid and two holes 14 are holes for the air outlet, of which, for example, air or other gases that are in the portion capsule, can be unreliable, at least from time to time of portions of the capsule when the piercing portion of the capsule and/or the flow of fluid. Here, the holes 14 are located above the holes 4 relative to the Earth's gravitational field. The removal of air is indicated by arrows 15. In this case, the holes 14 are located in the plane 5 of symmetry and symmetrically relative to the plane 6 of symmetry. Hole 4 for supplying the fluid located in this case in a vertical plane one above the other and asymmetrically relative to the plane 5 of symmetry of the unopened portion of the capsule, and means 10 for supplying the liquid in this case is located in the same plane 6 that both holes and 4, but between the two holes 4. After the gas letuce�Xia portion of the capsule, the holes 14 can function as holes for inlet of liquid. From the left image of Fig.7 it can be seen that, alternative or additionally, the portion capsule 1 may have a bottom hole 16 to remove air, which, preferably, be introduced into the portion capsule automatic coffee machine. This hole 16 for venting are in addition to the outlet 9 and serves to drain before perforation in the portion capsule of gas. Relative to the gravitational field of the Earth the hole 16 is located above the opening 9. Preferably, the opening 9 relative to the gravitational field of the Earth is above the holes 14.
