The level of technology

This invention relates to a portion capsule for preparing a beverage having performed essentially in the shape of a truncated cone or cylinder main element, which has a hollow space for accommodating the raw material for the preparation of drinks, and closing the hollow space of the membrane.

In General, such capsules are known. For example, from a printed publication FR 2556323 A1 known portion capsule, having performed in the form of a truncated cone or cylinder main element, which is used to prepare the drink, with the hollow space inside the capsules filled with the raw material for the preparation of drinks, especially coffee powder, and is closed by a membrane. For preparing a coffee beverage portion capsule is located in the brewing chamber, in which the membrane is perforated and extracting the liquid, especially hot water, is introduced into the hollow space. Extracting the liquid flows through the raw material for the preparation of beverages so that the formed extract drink, especially a coffee drink. In addition, in the brewing chamber lower part portion of the capsule is perforated so that the extract can drink out of the capsules and, if necessary, to get in the tank for a sentence is the service of drinks, such as, for example, a coffee Cup.

The disadvantage of this capsules is that the portion capsule has a relatively low mechanical stability. Extracting the liquid during the process of extraction is injected under pressure in the brewing chamber so that the portion capsule during the process of extraction is subjected to relatively high pressure. Therefore, there is a risk that the portion capsule side podaetsya, primarily at the wall area between the membrane and the bottom plot, and because of this raw material will not be evenly washed in the brewing chamber and/or extracting fluid will flow round portions camera in the brewing chamber side. As a consequence, the taste is subject to extraction drink significantly affected.

Disclosure of the invention

Therefore, the objective of the invention is the creation of capsules, which does not have the disadvantages of the prior art and, in addition, is relatively simple and inexpensive to manufacture.

This problem is solved by using the capsules for the preparation of the drink that has made essentially in the form of a truncated cone or cylinder main element, which has a hollow space for accommodating the raw material for the preparation of apitco is, and closing the hollow space of the membrane, characterized in that the wall section of the base element has multiple grooves.

Portion capsule according to the invention in comparison with the portion capsule of the prior art has the advantage that the wall section of the base element is given rigidity by many grooves. On the one hand, this has the advantage that the portion capsule has a higher mechanical stability and, thus, prevents deformation and, above all, the side fracture capsules. Thus, preferably, it is possible to provide an even wash of raw materials for making beverages in the brewing chamber, whereby it is possible to significantly improve the quality and reliability of the extraction process. First of all, increasing the mechanical stability through the use of multiple grooves leads to the fact that, in General, it is possible to reduce the thickness of the material of the base element. Thus, the manufacture of capsules is much more economical and more environmentally friendly. On the other hand, in the brewing chamber through a variety of grooves decreases or prevents adhesion of the wall section to the wall of the brewing chamber, whereby it becomes more favorable emissions, or remove portions the capsule from the brewing chamber. Another advantage of the many grooves is that the inside of the hollow space due to the structure of the grooves on the wall plot whirls for extracting fluid along the main area. More strong in comparison with the prior art swirl extracting liquid in the hollow space has the advantage that it does not form spontaneous and random flow of the main extracting liquid through the layer of raw material for the preparation of drinks, but instead raw materials for the preparation of drinks is washed in its entirety. Thus, the extraction process becomes much more efficient and can be more precisely controlled or repeatable. As an alternative, it is assumed that the wall of the capsule has a greater material thickness than the lower portion, so that the puncturing capsules on the lower section is simplified. Raw materials for the preparation of drinks contains, first of all, the coffee powder (preferably freshly ground roasted coffee), chocolate powder, milk powder, tea or similar. As an alternative, it is assumed that the raw materials for the preparation of drinks infused beverage, such as, for example, instant coffee.

Grooves in the sense of this invention are, first of all, bulges or indentations, which, preferably, have LINENO the main length. Particularly preferably, the grooves made in the form of belts and/or grooves. With optional grooves made on facing the hollow space of the inner side and/or facing away from the hollow space of the outer side of the main element. Especially preferably, it is provided that the groove in each case extend essentially in parallel to the membrane plane, with grooves, preferably, in each case provided abagusii around the main element, for example, in the form obecause around the main element parallel to the membrane and is essentially a mud rings.

According to the following subject matter or a preferred improvement of this invention provided that the membrane is made rough, at least on facing away from the hollow space of the outer side. Thus the preferred way reduces or prevents adhesion of the membrane to facing the membrane wall of the brewing chamber, so that simplifies the release or the notch portion of the capsule from the brewing chamber after the extraction process. First of all, the brewing chamber with automatic release mechanism there is a threat that release capsules operates reliably, because after the extraction process, the wall portions of the chamber or membrane p is Rinnai camera sticks to the wall of the brewing chamber. The reason for this can be, for example, electrostatic forces of attraction between the wall portions of the chamber and the wall of the brewing chamber and/or the appropriate voltage to the liquid surface between the wall portions of the capsule and the wall of the brewing chamber. These effects are significantly reduced by structuring the walls of the capsules, for example, by the roughness of the membrane and/or by the location of the grooves on the wall section, so that in comparison with the prior art provides reliable automatic ejection of capsules from the brewing chamber. The structuring of the membrane occurs through the fact that the membrane on the outer side provided with a protective film. Alternatively, it is acceptable to roughen the membrane, for example, by using laser irradiation.

According to the following subject matter or a preferred improvement of this invention provides that the wall section of the base element has a ledge. A preferred manner, the protrusion enables stacking of multiple portions of the capsules before filling portions of the capsules. Time before filling portions capsules raw material for making beverages, portion capsule has no raw materials for the preparation of beverages or membrane. Therefore, empty capsules, and the first of all the basic elements, it is possible to stack a stack one at each other, whereby is made possible relatively compact arrangement of the many empty portions of the capsules. This reduces primarily the cost of transportation and storage. Portion capsule according to the invention is now made in the form of the edge of the ledge for stacking, whereby the two are inserted into each other capsules are held at a distance relative to each other. When this portion of the capsule lies ledge to another portion capsule. Preferably, the portion capsule contains flange, to which is attached the membrane, while the protrusion in each case is made adjacent to the flange. A preferred manner, the protrusion of one capsules now rests on the flange of the other capsules. The preferred way, both flanges of the two inserted one in the other portions of the capsules are at a distance from each other in accordance with the height of the ledge. The preferred way to delete from each other both inserted one into each batch of capsules, each flange can be relatively easy to capture, especially mechanized. In addition, due to the location at the distance of both installed at each other portions of the capsules prevents the formation of reduced pressure between the portions of the capsules, so empty capsules can be reliably and simply again separated from each other. Portion capsule according to p. 7 claims, characterized in that the portion capsule has a flange, which is fixed to the membranes, the protrusion is made adjacent to the flange. Preferably, the main element in projection in a plane parallel to the membrane includes an enlarged diameter. Especially preferably, it is envisaged that the main element tapers in the region of the protrusion in the direction of the membrane. Preferred effectively eliminates the sliding protrusions of the two installed at each other blank portions of the capsules. The location at the distance of both portions of the capsules from each other reliably provided when large axial forces. It is of great importance for stacking relatively large number of blank portions of the capsules. The narrowing of the protrusion in the direction of the membrane has the advantage that the portion capsule can be maintained by the incoming engages in an intermediate region between the flange and the protrusion of the holder or manipulator, for example in the brewing chamber when filling the brewing chamber or during the manufacture of the capsules, the holder or manipulator is automatically centered between the flange and the ledge. Thus, the protrusion has semienterprise action.

According to the next subject or preferred the improvement of the present invention is provided, that portion capsule has a flange attached to the membrane, the ratio of the outer diameter adjacent to the flange wall section of the base element to the outer diameter of the flange is between of 0.79 and 0.95. Therefore, a preferred manner, the flange is made relatively large compared to adjacent to the flange wall section, so that, on the one hand, achieve a sufficiently large surface adhesion on the flange for stable fastening of the membrane to the flange and in the manufacture of capsules, for example, by the method of deep drawing reaches a relatively simple alignment of the hollow space in the area of the flange. First of all, therefore, reduces the required tolerances on the manufacture, so that it is possible, in General, to reduce production costs. On the other hand, the flange compared with the wall section is made sufficiently small, so that the lever arm between the flange and the wall area is small. The preferred way, this leads to the fact that the force on the flange does not lead to undesirable deformation of the wall section. Preferably, the ratio of the outer diameter adjacent to the flange wall section of the base element to the outer diameter of the flange is between 0,85 and 0,89 and, above all, is essentially 0,87. Thus, preference is sustained fashion way an optimum compromise between large tolerances in manufacture, on the one hand, and low material consumption, on the other hand. In addition, an optimum compromise between a good adhesion between the flange and the membrane, on the one hand, and short mechanical lever arm between the flange and the wall section. Especially preferably, it is provided that the outer diameter adjacent to the flange wall section of the base element is essentially a 39 millimeters and/or outer diameter of the flange is essentially 45 millimeters.
