  • the rim of the capsule is pressed against a surface in the chamber to form a sealed engagement.
  • the sealed engagement with the chamber is typically used to insure that all of the hot water is passed through the capsule for preparation of the coffee beverage and to prevent leakage around the capsule.
  • U.S. Patent No. 4,136,202 entitled “Capsule for beverage preparation,” the content of which is incorporated herein by reference describes a capsule containing a substance for making up a drink using an apparatus.
  • the capsule includes a body having the general shape of an acute truncated cone with a rim and a membrane positioned over the rim to seal the capsule body.

  • the present invention in some embodiments thereof, relates to a single use capsule for storing one or more ingredients for preparation of a beverage and, more particularly, but not exclusively, to a capsule for storing the one or more ingredients in an environment that is impermeable to oxygen and moisture.
  • shelf life and quality of a product stored in a plastic capsule is often limited due to permeability of the capsule to oxygen, moisture and ultraviolet radiation. This is particularly the case when the capsule is used to store a ground product such as coffee or tea leaves.
  • Capsules formed from polymer and/or plastic material are typically significantly more permeable to oxygen, moisture and UV radiation as compared to capsules formed from aluminum sheets.
  • the present inventors have found that shelf life and quality of a product stored in a plastic capsule can be significantly improved by coating the capsule with a thin layer of metallic material and additional outer layer of Silicon Oxide (SiO x ), e.g. Si0 2 .
  • SiO x is used to prevent oxidation of the metal coating.
  • the thin layer of metallic material is metal aluminum (Al).
  • Al metal aluminum
  • an Aluminum Oxide (A1 2 0 3 ) is used instead of the metal coating.
  • a nickel and/or chrome coating is used in place of aluminum.
  • a SiOx coating is used without the metallic layer.
  • a diamond like carbon (DLC) coating is used.
  • a primary coating of silicon monoxide is applied on the capsule to improve adhesion of the metal coating.
  • PVD physical vapor deposition
  • the present inventors have found that metallic aluminum and SiO x coating applied on an otherwise permeable material such as plastic can improve the resistance of the capsule to penetration of oxygen, moisture and UV radiation.
  • a plastic capsule with a thin layer of metallic aluminum and SiO x may provide a level of impermeability that is comparable to a capsule composed of sheet aluminum between 60 and 110 ⁇ thick.
  • the plastic capsule with a metallic and SiO x coating is also suitable for recycling and/or more suitable for recycling as compared to capsule formed from sheet aluminum.
  • the metallic and SiO x coating over the plastic capsule is typically thin enough so that it does not interfere with the plastic recycling process.
  • known aluminum capsules typically include a relatively thick layer of plastic, e.g. in the order of magnitude of about 30 microns that does interfere with the process for recycling the aluminum.
  • manufacturing cost for a coated plastic capsule may be lower than that for capsule composed of sheet aluminum.
  • the coating is not applied on the rim area of the capsule, e.g. the polymer material of the rim is left bare to enhance a fluid seal provided by the rim when engaged in a chamber of a beverage machine.
  • the present inventors have also found that the mirror finish look provided by an outer metallic layer, e.g. aluminum, nickel and/or chrome adds an attractive feature that can aid in marketing the capsule.
  • FIGS. 1A and IB shows a simplified schematic perspective and cross-sectional view of a coated capsule in accordance with some embodiments of the present invention.
  • a capsule 100 includes a body 50 defining a volume for containing a product and a rim and/or flange 20 over which a membrane 30 is attached for sealing capsule 100.
