[0002] Portion capsules for drinks or other food products are known from the prior art. The cup-shaped bowl is preferably formed in a truncated-cone-like manner or cylindrically and has a base and a covering face. It is produced, for example, from a deep-drawn plastics film or with the plastic material injection-molding method.
At a side opposite the base, there are provided a filling opening and a seal edge which surrounds the filling opening and on which a covering film is applied, in particular sealed, after the portion capsule has been filled.
[0003] In order to produce specific drinks or food products, a filter element has to be inserted into the portion capsule.
[0004] An installation for producing a portion capsule having a filter element is known, for example, from EP2093148 Al, wherein the installation has a single forming and inserting device in order to form in one step individual cup-shaped filters which comprise a filter material and to insert each of these cup-shaped filters into a bowl, and wherein there is provided downstream of this forming and inserting device a welding device, by -means of which an edge of each cup-shaped filter is welded to an upper seal edge of the associated bowl.
PROBLEM AND SOLUTION
[0005] Objectives of the invention are to provide a method and an installation for producing a portion capsule which is improved for subsequent handling and an improved portion capsule.
[0006] These objectives are achieved by the aspects of subject-matter having the features of claims 1, 6 and 11.
Advantageous embodiments are described in the dependent claims.
[0007] According to a first aspect, there is provided a method for producing a portion capsule for drinks and food products having a cup-shaped bowl comprising a seal edge, a base and a covering face and having a cup-shaped filter element which is inserted into the bowl and in which a product is introduced, comprising the steps of:
(a) forming a filter element from a forming piece comprising a filter material; (b) inserting the filter element formed into a cup-shaped bowl; (c) connecting an edge of the formed filter element to a seal edge of the cup-shaped bowl; and (d) connecting the filter element to the base and/or the covering face of the bowl.
[0008] By the filter element being connected to the base and/or the covering face of the bowl, subsequent handling is improved. In this instance, the connection locations are preferably selected so that separation of the filter element is not carried out when the portion capsule is pierced during use for dispensing the drink.
[0009] Connection of the filter element to the seal edge of the bowl and/or the base or the covering face is preferably carried out by means of an adhesive, melt or seal connection.
[0010] In one embodiment, simultaneous connection of the filter element to the seal edge and the base or the covering face is carried out. In advantageous embodiments, steps c) and d) were carried out separately.
[0011] In this case, in an advantageous embodiment there is provision for the filter element to be preformed in step a), wherein the preformed filter element is brought into a definitive form before or during step d).
[0012] In an embodiment, the forming piece is stamped or cut out from a material web and formed in one step.

In other embodiments, all the devices are constructed separately, wherein the bowl or a plurality of bowls is/are transported to the devices successively in a product flow direction.
[0018] In an embodiment, the filter element can be brought into a definitive form by means of the first device. In advantageous embodiments, there is provided after the first device and before or at the fourth device a forming tool, by means of which the filter element inserted into the bowl can be brought into a definitive form before or during the fitting of the filter element to the base and/or the covering face of the bowl. By formation in the bowl, an optimum formation of the filter element is ensured.
[0019] In an embodiment, the first device is constructed in such a manner that stamping and forming of the filter element are carried out by means of the first device. In advantageous embodiments, a stamping or cutting device for stamping or cutting out the forming piece from a material web is provided in the product flow direction upstream of the first device.
[0020] There is preferably provided a transport device, by means of which bowl or in series production a large number of bowls can be transported in the product flow direction during production of the portion capsule. The bowls are preferably connected to each other in the product flow direction.
[0021] In advantageous embodiments, the installation has a stamping device downstream of the device for fitting the filter element to the base and/or the covering face of the bowl, wherein the bowl with the filter element inserted can be brought into a final form by means of the stamping device and/or the bowls which are connected to each other can be separated.
[0022] According to a third aspect, a portion capsule for drinks and food products having a cup-shaped bowl is provided, comprising a seal edge, a base and a covering face and having a cup-shaped filter element which is inserted into the bowl and in which a product can be -introduced, wherein an edge of the filter element is connected to the seal edge of the cup-shaped bowl and wherein the filter element is connected to the base and/or the covering face of the bowl.
