Definitions

  • the present invention relates to a capsule according to the preamble of claim 1 and a method for producing such a capsule.
  • Capsules which in particular are only used once and are disposed of after use, are now widely used as portion packs for the preparation of, for example, coffee or tea in a device. The consumer no longer has to worry about dosing the correct amount of coffee, for example, and after the extraction process the capsule and its contents can be disposed of.
  • a capsule containing a substance for beverage production which has circular openings or elongated slots in the bottom.
  • 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 capsule for receiving a substance for beverage production is known in which a base or a membrane of the capsule has areas of reduced thickness which can tear open during operation under the pressure of a supplied liquid.
  • a portion pack with a container, a base and a membrane is known, in which the base is perforated during operation by means of a piercing device for the supply of fluid.
  • a capsule which contains a substance such as coffee for the preparation of a beverage by brewing in a device.
  • This known capsule is usually made of aluminum sheet.
  • a plastic capsule which contains a substance for the production of a drink with a machine.
  • This known capsule is already less expensive to manufacture than aluminum, for example, and the energy consumption for its manufacture is also 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, as a result of which food of reduced quality may be produced if not enough liquid is conveyed through the capsule in accordance with the respective specifications.
  • a large overpressure arises in the device if the capsule is not penetrated and the supplied liquid cannot therefore be easily drained away, which may damage the device.
  • the overpressure can also pose a safety risk for the operator.
  • Another disadvantage of the known prior art is the need to include means for penetrating the capsule in the device, which is expensive.
  • a capsule is to be provided which can be used in a device for producing drinks without a penetration device.
  • the capsule according to the invention consists of a capsule body with a side wall and a bottom.
  • the capsule body is preferably designed to be rotationally symmetrical.
  • the capsule body is formed in one piece with the side wall and the bottom.
  • the capsule comprises a lid covering the capsule body to form a closed chamber which contains a substance for the preparation of a foodstuff.
  • the capsule body has at least one slot for the passage of a liquid through the capsule, which slot is formed essentially without material removal.
  • the slot in the capsule body is formed in a device for producing a food product before the capsule is used as intended.
  • the phrase “essentially without material removal” is understood to mean a non-cutting process with which the slot is formed, that is to say that 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 if a suitable cutting tool such as a knife is used.
  • the slot in the capsule body is formed before the intended use of the capsule in a device for the production of a foodstuff
  • the slot in the capsule body is formed during the production of the capsule body, after the production of the capsule body or after the filling and sealing of the capsule with a lid and the capsule with the slot in the capsule body is sold and stored.
  • a capsule in which a slot is formed during use in a device for the production of a food by a device of the device is therefore not a slot in the capsule body for the purposes of the present application, which is formed before the intended use of the capsule.
  • the slot can be produced with a knife and / or a laser.
  • the capsule is suitable for producing a foodstuff and in particular a drink in a device without a penetration device.
  • a “penetration device” is understood to mean a device with which the capsule can be penetrated and in particular pierced in the device when used as intended, so that liquid can be passed through the capsule.
  • rotationally symmetrical is understood to mean symmetry with respect to rotation about the longitudinal axis of the capsule by a discrete angle or also by any angle.
  • the formation of at least one slot in the capsule body has the advantage that if the penetration of the capsule body is possibly not reliable, the liquid can flow through the slot. This advantageously means that the creation of an overpressure in the device can be avoided, as a result of which the risk of damage to the device is reduced.
  • the arrangement of the slot in the capsule body makes it possible to achieve a more constant quality of the food produced, since at least a certain flow through the device is ensured.
  • the capsule according to the invention can be used in a device for producing a foodstuff without a penetration device.
  • coffee, tea and chocolate or any combination thereof can be used as the substance.
  • parameters such as the length of the slot, the wall thickness of the capsule body and the material of the capsule body or any combination of these parameters can advantageously influence the opening behavior of the slot when used as intended; For example, it is possible that the slot for the passage of a liquid only opens when a certain overpressure is reached in the device, which only exists if the capsule is not properly penetrated in the device; the slot can thus function as a safety valve and / or as a flow control device.
  • the opposite edges of the slot preferably touch at least in sections in a rest position.
  • the opposite edges of the slot preferably touch one another over at least 90% of a length l of the slot, in particular preferably to at least 95% and very particularly preferably to 100%.
  • the term “100%” is understood to mean contact over essentially the entire length l of the slot.
  • a “rest position” is understood to mean the position of the slot in which, for example, no force is exerted on the capsule body by the device for producing a foodstuff.
  • a force can be, for example, a mechanical force to deform the capsule body, as a result of which the slot would move from the rest position.
  • it can also be, for example, a hydraulic force that arises when a liquid is fed into the capsule under pressure to extract the substance in the capsule, for example for brewing a coffee drink.
  • the configuration of the slot in such a way that the opposite edges touch at least in sections in the rest position has the advantage that the capsule is essentially closed and no substance can get out of the capsule body.
  • the slot can be opened from a rest position into an open position by means of an action of force.
  • the slot can be opened by means of a mechanical and / or hydraulic force.
  • an “open position” of the slot is understood to mean that position of the slot in which the opposite edges of the slot are spaced apart by the action of force for the passage of the liquid.
  • the slot can be opened by generating a pressure difference at least in the area of the slot between the chamber and the outside of the capsule body, in particular when the pressure difference is generated by means of a liquid that can be supplied under pressure.
  • the slot can be opened by means of a pressure difference between the outside of the capsule and the inside of the capsule formed by the chamber.
  • the slot can essentially be closed reversibly and essentially returns to the rest position.
  • the slot remains essentially in the open position after opening by means of the action of force in the open position and the supply of thermal energy.
  • the slot remains in the open position after the pressure difference has been removed.
  • the slot remains in the open position if the liquid has a temperature greater than 70 ° C., preferably greater than 75 ° C. and particularly preferably greater than 80 ° C. for supplying the thermal energy.
