[001] The present invention relates to a portion capsule for the preparation of a beverage comprising a capsule body with a capsule bottom and a filling side, wherein between the capsule bottom and the filling side is A hollow space is formed for the reception of a substrate for the preparation of powder or liquid drinks and in which a filter element is arranged between the substrate for the preparation of drinks and the bottom of the capsule.
[002] Portion capsules of this nature are known in the art. EP 1792850 B1, EP 1344722 A1 and US 2003/0172813 A1, for example, disclose portion capsules for the preparation of coffee and Espresso.
[003] The portion capsules for the preparation of a drink are preferably molded in a truncated or cylindrical shape and are manufactured for example from a film of plastic material by deep embedding or in an injection molding process. They usually have an open filling side with a circumferential edge, on which a covering film is sealed or glued and a closed capsule bottom, in which a filter element is placed between the beverage preparation substrate and the capsule bottom. that rests against the capsule bottom. These filter elements are either molded by injection from a thermoplastic plastic material or by deep embedding or by stamping from a film of plastic material.
[004] For the preparation of a coffee drink the serving capsule is introduced into a preparation chamber by infusing a preparation device. After or during the procedure for closing the preparation chamber by infusion, preferably the portion capsule is opened on the respective bottom side by means of a flow device and / or an opening means arranged in the preparation chamber by infusion, for example, a perforation element, or an opening previously existing in the capsule bottom, is passed through the flow member and / or through the opening means. After sealing the preparation chamber by infusion, the filling side of the closed portion capsule by a closing film is perforated by means of at least one perforation means. Subsequently, a preparation liquid, preferably hot water, is transported to the portion capsule under pressure. The preparation liquid passes through the substrate for beverage preparation and extracts and / or dissolves the substances necessary for the preparation of the beverage from the substrate for beverage preparation. For the preparation of an Espresso, for the extraction of essential oils, for example, an infusion water pressure of up to 2 MPa (20 bar) acts on the coffee powder. This pressure, moreover, also acts on the filter element between the ground coffee and the capsule bottom and disposed before the perforated capsule leaves. The freshly brewed beverage preferably flows along the pouring organ and / or the opening means of the brewing infusion chamber to a receiving organ, for example a cup or glass.
[005] Accordingly, the present invention aims to provide a portion capsule with a filtering arrangement, which is easier to manufacture compared to the state of the art.
[006] This objective is achieved by means of a portion capsule for the preparation of a beverage comprising a capsule body with a capsule bottom and a filling side, wherein between the capsule bottom and the filling side is A hollow space is formed for the reception of a substrate for the preparation of powder or liquid drinks and in which between the substrate for the preparation of drinks and the bottom of the capsule a filter element is arranged and in which during the preparation of the drink a flow member and / or an opening means penetrates the hollow space through the capsule bottom, characterized in that the filter element is at least partially rigid and is provided in the vicinity or in the region of the capsule bottom and by the flow member and / or the opening means pricking, perforating and / or moving the filter element in relation to the capsule body.
[007] Compared with the state of the art, the portion capsule according to the present invention has the advantage that a large distance between the filter element and the bottom of the capsule does not have to be provided or does not have to be provided. Therefore, the portion capsule with the same amount of substrate for beverage preparation may be of a smaller size and / or the amount of substrate for beverage preparation may be increased. The filter element itself may have a simpler geometry. Surprisingly and unexpectedly, the filter element can be chopped, perforated or moved in relation to the capsule body, particularly the capsule bottom, without impairing the quality of the drinks. The beverage preparation device can be manufactured with higher tolerances. For example, the piercing element can be made longer, so it is ensured that the capsule is fully open, before hot water penetrates the portion capsule.
[008] The present invention relates to a portion capsule. Portion capsules for the preparation of a beverage of this nature are preferably molded in a tapered or cylindrical shape and are manufactured, for example, from a film of plastic material by deep embedding or in an injection molding process. They usually have an open filling side with a circumferential edge, over which a covering film is sealed or glued, a side wall region, which is usually provided in a cylindrical or truncated shape, and a capsule bottom, between which the substrate for preparing beverages and the capsule bottom is preferably arranged with a filter element which rests against the capsule bottom.
[009] These filter elements are at least partially rigid, that is to say for example or molded by injection from a thermoplastic plastic material or by deep embedding or by stamping from a film of plastic material. However, the filter element can also be manufactured from any other desired material, known to the person skilled in the art. For example, paper materials or materials similar to paper or natural substances can be considered. The filter element may have reinforcing ribs and / or channels for the conduction of the liquid. The filter element, particularly in the respective central region, may have a recess, in which the flow element and / or the covering medium is introduced, before coming into contact with the filter element and pricking, drilling and / or moving it in relation to the capsule body. The filter element has at least one region, in which the substrate for the preparation of beverages is retained, but which can be traversed by the extraction liquid. That is, for example, a region, which has a plurality of holes, whose cross section is selected so that the particles of the substrate for the preparation of drinks cannot pass or cannot pass in a significant way, but which are passed through the medium. of extraction, for example, hot water. The filtering element may have a region, which is not traversed by the extraction medium. This region can be found, for example, above the region, in which the flow organ or the opening means penetrates. This region can also be made from a different material than the rest of the filter element and / or have a different thickness. This region can, for example, have a higher elasticity than the rest of the filter element. Particularly during perforation or drilling this region can be at least temporarily plastically or elastically deformed. The filter element can be flat.
[0010] Between the filter element and the capsule bottom, a hollow space may be provided, that is to say the filtering element can at least partially be arranged at a certain distance from the capsule bottom. The filter element may, for example, rest on the capsule bottom only in the respective edge region and / or only be connected with the side wall of the portion capsule in the respective edge region.
[0011] According to the present invention, the filter element in the portion capsule is provided so that the flow device and / or opening means of the preparation apparatus comes into contact with the filter element at least temporarily before or during preparation of the drink and, therefore, the perforation, perforates and / or moves it in relation to the capsule body.
[0012] For the preparation of a coffee drink the serving capsule is introduced into a preparation chamber by infusing a preparation device. After or during the closing procedure of the brewing chamber, preferably the portion capsule is opened on the respective bottom side by means of a flow organ and / or an opening means arranged in the brewing chamber or an opening previously existing in the bottom of the capsule is crossed by the flow organ and / or by the opening means. In this case, the flow organ and / or an opening means comes into contact with the filter element by chopping, perforating and / or moving it in relation to the portion capsule. After sealing the brewing chamber by infusion, the filling side of the portion capsule closed by a closing film is perforated by means of at least one perforation means. Subsequently, a preparation liquid, preferably hot water, is transported to the portion capsule under pressure. The preparation liquid passes through the substrate for beverage preparation and extracts and / or dissolves the substances necessary for the preparation of the beverage from the substrate for beverage preparation. For the preparation of an Espresso, for the extraction of essential oils, for example, an infusion water pressure of up to 2 MPa (20 bar) acts on the coffee powder. This pressure, moreover, also acts on the filter element between the ground coffee and the capsule bottom and disposed before the perforated capsule leaves. The freshly brewed beverage preferably flows along the flow organ and / or the opening means of the brewing chamber by infusion to a receiving organ, for example, a cup or glass.
[0013] Preferably the portion capsule is hermetically closed. This means that the drinks or powdered foods contained in the serving capsule, for example, powdered coffee, powdered soup or tea, prior to the extraction procedure are essentially sealed in relation to the aromas of the environment. However, the portion capsule does not have to be hermetically sealed, but it can also be provided in a hermetically sealed package before use, which is then opened manually.
[0014] Preferably the filter element is simply inserted into the capsule body and subsequently sits on the bottom of the capsule loosely or is connected with it and / or with the side wall of the capsule, particularly before the substrate for preparing drinks be introduced into the capsule body.
[0015] Preferably the capsule body is molded in a truncated or cylindrical shape and is manufactured for example from plastic material, a natural substance and / or a biodegradable material from a plastic material film by deep embedding or in an injection molding process. Preferably the capsule body on the respective filling side has a circumferential edge, over which a covering film is sealed or glued. Alternatively, the capsule body and a capsule cap can be interconnected by means of a mechanical process. The bottom of the portion capsule is preferably closed and is preferably only perforated in the preparation chamber by infusion by means of a flow organ and / or an opening means that acts from the outside on the capsule bottom to generate an outlet opening . Alternatively, it would also be possible for the bottom of the portion capsule to be provided with an outlet opening at the manufacturing level, which would preferably be closed by a sealing film. In this case, the sealing film can, for example, be perforated by means of the perforation means or it can be manually removed from the capsule bottom. In the case of the sealing film, it is preferably a film of plastic material, which has at least one barrier layer, for example, a metallic layer, particularly an aluminum layer. The plastic film preferably on the side facing the capsule has a "peel layer", so that the plastic film can be removed relatively easily from the capsule bottom.
[0016] Preferably the outlet opening has a sufficiently large dimension for the contactless reception of a flow organ and / or any opening means that may exist. Particularly preferably, the outlet opening has a sufficiently large dimension that, during the exit of the prepared drink, there is no significant pressure loss, particularly no stirring of the prepared drink, which could lead to gas entering the drink and therefore, foaming.
[0017] According to another object or another embodiment according to the present invention, it is provided that the filter element is disposed in the hollow space of the portion capsule and rests on one side of the capsule bottom facing to the side filling. Advantageously, the manufacturing costs of the portion capsule are significantly reduced, considering that the filter element is simply introduced into the portion capsule loosely. A fixing of the filter element is advantageously carried out by the substance for the preparation of drinks, which during filling of the portion capsule is arranged on the filter element and, therefore, tightens the filter element.
[0018] According to another preferred embodiment of the present invention, it is envisaged that the edge region extends at least partially along a side wall region of the capsule body, the side wall region extending between the filling side and the capsule bottom.
[0019] According to a further preferred embodiment of the present invention, it is provided that the filter element covers totally or only partially the capsule bottom. In particular, it is sufficient when the filter element is arranged in the region of the perforation or in the region of the outlet opening at the bottom of the capsule.
[0020] According to another preferred embodiment of the present invention, it is provided that the filter element is fixed to the capsule bottom, preferably the filter element is fixed to the capsule bottom of the material union type, particularly by sealing. Therefore, it is advantageous to prevent the filter element from slipping. This fixation is preferably carried out by ultrasonic welding.
[0021] According to another preferred embodiment of the present invention, it is provided that the filter element is fixed in a region of the bottom of the capsule bottom and / or that the filter element is fixed in a region of the edge of the filter element in the side wall region. Consequently, the filter element slips advantageously and the sealing effect between the capsule body and the filter element is increased, while at the same time it is still possible to raise the filter element.
[0022] According to another preferred embodiment of the present invention, it is provided that the capsule bottom has a recess in a direction opposite to the filling side. Advantageously, this recess serves to receive the drilling medium.
[0023] According to another preferred embodiment of the present invention, it is provided that the capsule bottom has a predetermined breaking point, which is intended to break, following a mechanical contact with an external piercing means, being that preferably the predetermined breaking point has a plurality of stellar lines of weakness arranged around a central point of the capsule bottom. Preferably the bottom of the capsule along the lines of weakness has a reduced thickness and / or along the lines of weakness is perforated. Advantageously, the perforation of the capsule bottom is favored by the realization of the predetermined breaking point. This has the advantage that a less cutting drill tip can be used for drilling the capsule bottom, so that the risk of damaging the filter element during the lifting of the filter element by the drill tip is reduced. Particularly, a blunt drilling medium is sufficient for drilling the capsule bottom.
[0024] According to another preferred embodiment the capsule bottom permanently has an outlet opening, which is preferably sealed with a film, wherein the film particularly preferably has a removal element for removing the film manually. In this case, advantageously, no perforation of the capsule bottom is necessary by means of an external perforation means. Before inserting the portion capsule into the brewing chamber, the film is removed from the capsule bottom by means of the removal tab and the brewing procedure can be started. This embodiment has the advantage that the liquid for the preparation of drinks does not come out of the outlet opening under a high pressure and, therefore, the formation of foam ("cream") is avoided, particularly during the preparation of coffee American or tea.
[0025] Another preferred object of the present invention is a process for the preparation of a beverage with a portion capsule, in which in a first process step the portion capsule is provided with a rigid filter element, in a second stage process, the capsule bottom is crossed by a flow organ and / or by an opening means and in a third process step the filter element is chopped, perforated and / or moved in relation to the capsule body by the flow organ and / or through the opening means.
[0026] This pricking, perforation and / or movement in relation to the capsule body is preferably carried out during the introduction of the portion capsule into the preparation chamber for infusion and / or during the closing of the preparation chamber by infusion.
[0027] The embodiments of the present invention in relation to one object are equally applicable to other objects in the same way or in an inverse way.
[0028] Another object of the present invention is the use of a portion capsule for the preparation of a beverage, preferably for the preparation of a coffee, cocoa, tea and / or milk beverage.

[0040] In Figure 1, a first embodiment of the portion 1 capsule according to the present invention is shown. The portion capsule 1 comprises a truncated capsule body 2 with a closed capsule bottom 3 and with a circumferential edge 5 disposed on the respective filling side 4, on which a covering film 6 is welded or glued 6 Therefore, between the capsule bottom 3 and the covering film 6, a hollow space 100 is formed, preferably sealed to air and aromas, which is filled with a substance for the preparation of drinks 101 in powder or in the form of grainy. The beverage preparation substance 101 in this case comprises a powder (or granulate) of coffee, cocoa, tea and / or milk. On the inner side 3a of the bottom of the capsule body 3, that is to say within the hollow space 100, a rigid filter element 7, made of a plastic material, is arranged. The filter element 7 either rests on the inner side 3a of the capsule bottom 3 or is fixedly connected, preferably of the material union type, with the inner side 3a of the bottom of the capsule body 3. According to a second variant, the filter element 7 it is only fixed, of the material union type, on the capsule bottom 3 in a peripheral region 3 'of the capsule bottom 3. In the present case the filter element is made at least partially rigid. The filter element is, for example, a component molded by casting, by injection molding, by deep embedding and / or by stamping.
[0041] In Figure 2 a portion 1 capsule according to the first embodiment of the present invention illustrated in figure 1 is shown, wherein the portion 1 capsule in Figure 2 is arranged in a closed infusion preparation chamber 8 . The infusion preparation chamber 8 consists of a first element of the infusion preparation chamber 9 and a second element of the infusion preparation chamber 10, wherein the first element of the infusion preparation chamber 9 for inserting the capsule portion 1 is provided on the side opposite the second element of the brewing chamber 10 and vice versa. A seal 11 is arranged between the two brewing chamber elements 9, 10. The first brewing chamber element 9 consists essentially of a closing piston 12 with perforating elements 13a, 13b for opening the film cover 6 of the portion 1 capsule, a supply for preparation liquid 14 and the seal 11. The second element of the infusion preparation chamber 10 consists essentially of an infusion preparation chamber bell 15 that partially embraces the portion capsule 1 with an opening element 16 disposed at the bottom of the brewing chamber bell 15, which is provided with flow slots 17, and a beverage outlet 18. For receiving portion capsule 1 the delivery chamber infusion preparation 8 is in an open state not shown, where the first and second elements of the infusion preparation chamber 9, 10 are spaced apart from each other, to allow a feed of the portion 1 capsule, and in the closed state shown, in which a preparation procedure can be carried out for the preparation of a beverage by means of the portion 1 capsule. In the closed state the brewing chamber 8 is closed tightly under pressure. During the transition from the brewing chamber 8 from the open to the closed state shown, the cover film 6 is perforated by the drilling elements 13a, 13b so that a brewing liquid, particularly hot water, penetrates the hollow space 100 of the portion capsule 1 due to the supply of preparation liquid 14 under pressure. In addition, during the closing of the brewing chamber 8, the bottom of the capsule 3 is perforated by the flow member and / or by an opening means realized as an opening spike 16, so that an outlet opening 107 is generated in the capsule. portion 1, through which the prepared beverage liquid can exit the portion 1 capsule towards the beverage outlet 18. To assist in the conduction of the beverage liquid, the opening element 16 has flow grooves 17 on the respective coating surface . In the representation, the bottom 3 of the portion 1 capsule in the brewing chamber 9, 10 is perforated by the opening element 16 of the second brewing chamber element and the filtering element 7 above the breaking point is slightly raised perforating element 19 of opening element 16, being pricked but not perforated. The capsule bottom 3 at the respective central point 106, where the capsule bottom 3 is perforated by the opening spike 16, optionally has a breaking point 104, so that a relatively blunt opening spike 16 is sufficient for the perforation of the capsule bottom 3.
[0042] After penetration of the flow organ and / or an opening medium in the portion capsule, the liquid, during the preparation of coffee, for example hot water, flows into the capsule 1. In the capsule this liquid passes through the substrate to the beverage preparation 101 and extracts and / or dissolves the substances necessary for the beverage preparation from the beverage preparation substrate 101. The flow of the liquid in the beverage preparation substrate 101 is illustrated by reference number 22. Subsequently the beverage The resulting liquid flows through the filter element 7 disposed between the beverage preparation substrate 101 and the capsule bottom 3, which prevents particles of the substrate for beverage preparation 101 in the form of particles from penetrating the resulting beverage and, through of the perforated opening at the bottom of the capsule 3 by means of the opening spike 16 and by means of the drainage slots 17 of the opening spike 16 penetrate the receiving container, for example a key on or a teapot.
