Definitions

  • the invention relates to an extraction method and capsules for receiving an extraction material, in particular coffee, for use in an extraction machine, in particular a coffee machine.
  • such coffee maker sachets are in the form of capsules having a bottom, a sidewall, a flange-like rim, and a lid.
  • the floor, sidewall and lid are generally made of an air impermeable material such as aluminum to maintain the quality of the extraction material.
  • the capsule is inserted into a holder of the extraction machine. Then, the bottom of the capsule is opened with an injection device for an extraction fluid. Subsequently, the extraction fluid is passed under pressure into the capsule, whereupon the lid - or the part referred to here as the contact layer - ruptures and the extract can escape.
  • the contact layer is usually pressed (by the pressure) against a plate (hereinafter referred to as the "die") of the extraction machine, which has raised areas and channels between these raised areas, These structures normally predetermine the break points in the contact layer of the lid.
  • the channels are provided with openings that pierce the plate and through which the coffee can flow (see, for example, DE 692 17 113 T2).
  • the opening mechanism of the capsules also differs.

  • Gimoca is also pursuing a single-layer concept with aluminum foil as cover material and the same opening mechanism as Nespresso.
  • the cup is made of plastic and has a closed by aluminum foil water inlet, which opens due to the pressure of the extraction fluid (no secondary packaging).
  • the company Sara Lee produces single-layered open capsules that consist of an already pre-punched plastic film. Since the plastic cup (water inlet) and the lid are already pre-punched, each capsule needs a secondary packaging.
  • the Ethical Coffee Company offers a capsule that realizes a two-layer concept in terms of lid construction. The capsule has set back a foil bottom, which opens under pressure. A tear-resistant filter made of paper fleece ensures that the coffee grains are held back. There is a secondary packaging for each 10 pieces provided because the capsule has so far no pronounced barrier.

Abstract

L'invention porte sur une capsule destinée à recevoir un produit d'extraction comme le café et à être utilisée dans une machine d'extraction. La capsule présente un fond (27), une paroi latérale (25) solidaire du fond (27), une ouverture située à l'opposé du fond (27) et un couvercle (13) servant à obturer l'ouverture (12). Le couvercle (13) est muni d'une couche de sortie (14) en matière plastique servant pour la sortie de l'extrait hors de la capsule. Cette couche de sortie (14) présente une multiplicité de zones d'affaiblissement (17) qui sont conçues pour se déchirer sous l'effet de la pression, agissant de l'intérieur de la capsule (11) vers l'extérieur, du fluide d'extraction que l'on fait passer à travers la capsule (11) et pour former ainsi une multiplicité d'ouvertures de filtre qui sont suffisamment petites pour que le produit d'extraction ne puisse pas sortir à travers les ouvertures de filtre.
