  • portion packs for the preparation of, for example, coffee or tea in a device.
  • the consumer no longer has to worry about dosing the right quantity of coffee, and after the extraction process, the capsule and its contents can be disposed of.
  • a capsule containing a beverage-making substance having circular openings or elongated slots in the bottom is known.
  • a capsule for receiving a substance for beverage production is known, in which slots are arranged in the lid, which can be opened by means of an opening device.

  • a plastic capsule containing a substance for making a beverage with a machine is known.
  • This known capsule is already less expensive than, for example, aluminum in the production and the energy consumption for their production is reduced compared to the known aluminum capsules.
  • this known capsule has the disadvantage that the plastic capsule is often not reliably penetrated in the machines for food production, which may produce food of reduced quality, if not enough liquid is conveyed according to the respective specifications by the capsule.
  • a large overpressure arises when the capsule is not penetrated and the supplied liquid is thus not easily dissipated, whereby the device may be damaged.
  • the overpressure can also create a safety risk for the operator.
  • a capsule is to be provided, which can be used in a device for producing drinks without penetrating device.
  • the capsule according to the invention consists of a capsule body with a side wall and a bottom.
  • the capsule body is preferably rotationally symmetrical.
  • the capsule body is integrally formed with the side wall and the bottom.
  • the capsule comprises a lid covering the capsule body to form a closed chamber containing a substance for the preparation of a food.
  • the capsule body has at least one slot for the passage of a liquid through the capsule, which is formed substantially without material removal. The slot in the capsule body is formed prior to the intended use of the capsule in a device for producing a food.
  • the expression "substantially without removal of material” means a non-cutting process with which the slot is formed, that is, essentially no material is removed from the capsule body during the formation of the slot. This can be achieved, for example, with a cutting method when using a suitable cutting tool such as a knife.
