Method for producing a beverage using a portion capsule
A portion capsule for producing a beverage is proposed, having a capsule body with a capsule base and a filling side, with a cavity for accommodating a pulverulent or liquid beverage base being formed between the capsule base and the filling side, with a filter element being arranged between the beverage base and the capsule base, and with the filter element having a non-woven which is arranged in the region of the capsule base.
1. A method for producing a beverage using a portion capsule comprising a capsule body with a capsule base and a cover, a cavity for accommodating a pulverulent or beverage base being formed between the capsule base and the cover, and a filter element arranged between the beverage base and the capsule base, the filter element comprising a non-woven which is arranged on an inner side of the capsule base, the method comprising:
wherein the portion capsule is provided in a first method step, wherein the capsule base is perforated by means of an external perforation means in a second method step, and wherein the filter element is at least partially spaced apart from the capsule base in a third method step;
wherein, in the third method step, the filter element is spaced apart from the capsule base only in a central region and continues to rest on the capsule base or remains attached to the capsule base in the edge region of the capsule base;
delivering a preparation liquid into the portion capsule and through the pulverant or beverage base, the filter element and the capsule base, and
discharging the beverage.
2. The method as claimed in claim 1 , wherein the filter element is at least partially stretched when the central region is spaced apart from the capsule base.
3. The method as claimed in claim 2 , wherein an edge region of the filter element which projects in the direction of the cover moves in the direction of the capsule base when the central region is spaced apart from the capsule base during the third method step.
4. A method for producing a beverage using a portion capsule comprising a capsule body with a capsule base and a cover, a cavity for accommodating a pulverulent or beverage base being formed between the capsule base and the cover, and a filter element arranged between the beverage base and the capsule base, the filter element comprising a non-woven which is arranged on an inner side of the capsule base, the method comprising:
wherein the portion capsule is provided in a first method step, wherein the capsule base is perforated by means of an external perforation means in a second method step, and wherein the filter element is at least partially spaced apart from the capsule base in a third method step;
wherein, when the central region is spaced apart from the capsule base during the third method step, the filter element comprising a material reservoir having a corrugated or folded region, the material of the filter element moves out of a material reservoir in the direction of the capsule base, with the corrugated or folded region of the filter element being at least partially smoothed;
delivering a preparation liquid into the portion capsule and through the pulverant or beverage base, the filter element and the capsule base; and
discharging the beverage.
