Definitions

  • the present invention concerns an ingredient capsule for use in a food preparation machine, for instance in a liquid food preparation nnachine.
  • Beverage preparation machines are well known in the food science and consumer goods area. Such machines allow a consumer to prepare at home a given type of beverage, for instance a coffee-based beverage, e.g. an espresso or a brew-like coffee cup.
  • a coffee-based beverage e.g. an espresso or a brew-like coffee cup.
  • beverage preparation machines for in-home beverage preparation comprise a system made of a machine which can accommodate portioned ingredients for the preparation of the beverage.
  • Such portions can be soft pods or pads, or sachets, but more and more systems use semi-rigid or rigid portions such as rigid pods or capsules.
  • the beverage machine of the invention is a beverage preparation machine working with a rigid or semi-rigid capsule.
  • the machine com prises a receptacle or cavity for accommodating said capsule and a fl uid injection system for injecting a fl uid, preferably water, u nder pressure into the capsu le.
  • Water injected under pressure in the capsu le, for the preparation of a coffee beverage according to the present invention is preferably hot, that is to say at a tem peratu re above 70°C. However, in some particu lar instances, it might also be at ambient temperature, or even chilled.
  • the pressure inside the capsu le chamber du ring extraction and/or dissolution of the capsu le contents is typical ly about 1 to about 8 bar for dissolution prod ucts and about 2 to about 12 bar for extraction of roast and grou nd coffee.
  • Such a preparation process differs a lot from the so-cal led "brewing" process of beverage preparation - particu larly for tea and coffee, in that brewing involves a long time of infusion of the ingred ient by a fl uid (e.g. hot water), whereas the beverage preparation process allows a consu mer to prepare a beverage, for instance coffee, within a few seconds.
  • the principle of extracting and/or dissolving the contents of a closed capsu le u nder pressure is known, and consists typical ly of inserting the capsu le in a receptacle or cavity of a mach ine, injecting a quantity of pressurized water into the capsule, generally after piercing a face of the capsule with a piercing injection element such as a fl uid injection need le mounted on the machine, so as to create a pressurized environ ment inside the capsu le either to extract the substance or dissolve it, and then release the extracted su bstance or the dissolved su bstance through the capsule.
  • Capsules allowing the application of this principle have al ready been described for example in appl icant's European patents n° EP 1472156 Bl, and EP 1784344 Bl.
  • the mach ine comprises a receptacle or cavity for the capsu le and a perforation and injection element made in the form of a hollow need le comprising in its distal region one or more liqu id injection orifices.
  • the needle has a d ual fu nction in that it opens the top portion of the capsule on the one hand, and that it forms the water inlet channel into the capsule on the other hand.
  • the nnachine further comprises a fluid tank - in most cases this fluid is water - for storing the fluid that is used to dissolve and/or infuse and/or extract under pressure the ingredient(s) contained in the capsule.
  • the machine comprises a heating element such as a boiler or a heat exchanger, which is able to warm up the water used therein to working temperatures (classically temperatures up to 80-90°C).
  • the machine comprises a pump element for circulating the water from the tank to the capsule, optionally though the heating element.
  • the way the water circulates within the machine is e.g. selected via a selecting valve means, such as for instance a peristaltic valve of the type described in applicant's European patent a pplication EP 2162653 Al.
  • the beverage to be prepared is coffee
  • one interesting way to prepare the coffee is to provide the consumer with a capsule containing roast and ground coffee powder, which is to be extracted with hot water injected therein.
  • the machine comprises a capsule holder for holding a capsule, which is intended to be inserted in and removed from a corresponding cavity or receptacle of the machine.
  • the water injection means of the machine can fluidly connect to the capsule to inject water therein for a food preparation, as described above.
  • a capsule holder was described for example in applicant's European patent EP 1967100 Bl.
  • Capsules have been developed for such an application of food preparation, and in particular for beverage preparation, which are described and claimed in applicant's European patent EP 1784344 Bl, or in European patent application EP 2062831.
  • capsules comprise typically:
  • - a hollow body and an injection wall which is impermeable to liquids and to air and which is attached to the body and adapted to be punctured by e.g. an injection needle of the machine, - a chamber containing a bed of roast and ground coffee to be extracted, or a soluble ingredient or mix of soluble ingredients,
  • the aluminium membrane is designed for being pierced with piercing means that are either integral with the capsule, or located outside of said capsule, for example within a capsule holder of the machine.
  • the piercing means are adapted for piercing dispensing holes in the aluminium membrane when the internal pressure inside the chamber reaches a certain pre-determined value.
  • the capsule can further comprise means configured to break the jet of fluid so as to reduce the speed of the jet of fluid injected into the capsule and distribute the fluid across the bed of substance at a reduced speed.
  • Capsules of the prior art feature an injection wall or membrane
  • top membrane which is to be pierced by a fluid injection element (e.g. needle) of a beverage preparation machine being part of a fluid system.
  • a fluid injection element e.g. needle
  • a pressure is built up, which serves as an extraction means for extracting and/or dissolving ingredients contained inside the capsule, as described above.
  • ingredients can be for instance a bed of roast and ground coffee.
  • the ingredients can comprise soluble ingredients, such as for instance beverage premixes.
  • the capsule is opened both at an inlet side and at an outlet side.
  • the biggest portion of the liquid introduced into the interior of the capsule will be drained from the water, there will always some residual liquid remaining in the capsule after the beverage production process.
  • the capsule is then taken out from the beverage production machine, there is the problem of water or beverage dripping e.g. from the water inlet side of the capsule.
  • Such dripping forces to consumer to leave ones cup below the capsule dispensing outlet several seconds after the completion of the dispensing which is undesirable.
  • dripping can also cause messiness in or around the machine, in case the consumer has removed the cup from below the dispensing outlet, which is also undesirable. It is thought that this dripping is particularly promoted by air entering the capsule from the beverage outlet side.
  • the invention therefore has the object to reduce the risk of residual liquid dripping out of the capsule after the completion of the beverage production process.

  • Such alternative shapes can be beneficial in allowing products to flow and be dispensed to a consumer cup, which have various viscosities, and optionally contain small edible particles, like for instance croutons, small herb or fruit pieces, etc., while providing good anti-dripping properties to the capsule after dispensing of the beverage.

At this time, the slits do not reclose completely due to their plastic deformation during the beverage dispensing step. However their width is reduced sufficiently to provide a capillarity effect, due to the elastic properties of their constitutive material, such that the remaining liquid inside the capsule does not drip by gravity, and is retained within the capsule.
