Definitions

  • This invention deals about a new creative development for the in-situ preservation of coffee inside infusion-type bags.
  • the small amount of powdered coffee normally about 4-5 grams, remains stored for some time - several months- till the moment of use, i.e. opening of the unit and preparation of the infusion in a cup of water.
  • the oxygen of the air that has been kept inside the inner bag and between the bag and the outer seal attacks the free (loose) particles of coffee, degrading them by oxidation of its essential oils.
  • the proposed solution - and this is the core of the invention - is giving the filter bag a tubular, elongated shape, allowing the storage of a amount of powdered coffee at one of its ends in a ball-like shape (never as a sheet), but leaving empty a good part of the said tubular body, making room for the free movement of the coffee at the moment of using the bag, and allowing a good contact and dispersion of the particles in the water or liquid used to make the infusion (i.e. milk).
  • the present invention includes a self-sufficient unit of bag for the infusion of coffee and its protective cover, and that its characteristics are: a filter paper bag with a general tubular, elongated shape, sealed and holding a predefined amount of powdered coffee, occupying only part of the inner capacity of the bag, the relationship between the amount of powdered coffee and the inner capacity of the bag being such that, in the operative immersed position of at least part of the bag inside the amount of liquid where the infusion will be made, this amount of coffee has room enough to move and get in wide contact with the liquid, and with the bag having also an elongated shape, leaving room at one of its ends for the total amount of coffee, and allowing the forming of a slightly compacted ball, the free part of the bag's tubular body being plied around the end containing the said ball of coffee, contributing to its external shape, and providing also an external envelope for the plied bag, made up by an airtight capsule of an isolating layer that acts
  • a main objective of the present invention is getting an integrated construction of a coffee bag with its envelope-container, having an effective ability to preserve the coffee by really minimizing the air inside, and thus the detrimental oxygen that makes part of this air.
  • Another important objective of the present invention is the making of a bag with a good and effective ability for making infusions of coffee.
  • Still another important objective of the present invention is the making of the double structure of bag and its protecting envelope by simple procedures, both concerning the intervening material and the manufacturing process.
  • FIGS. 1 and 2 are a combination of filter bag containing powdered coffee, and its isolating envelope. Such a combination has already been used in previous attempts with little success, due to the reasons already explained.
  • (figures 1 and 2) -a- is a conventional, "ravioli" type filter bag, made up by two squares or rectangles -1- of thermosealable filter paper, soldered together by their edges -2-.
  • the said filter paper bag is put inside an envelope -c- with the same shape that of bag -a- but somewhat bigger, in order to contain the bag. It is made with two squares or rectangles -5- of a film that acts as a barrier against air, like polypropylene, cellophane, etc, soldered at their edges -6-.
  • a sachet or capsule -f- (figures 6 and 7), made of a sheet or film of polypropylene or other material that acts as a barrier against oxygen, and if this sachet is dimensioned so it fits tightly around the coffee bag, it is evident that no space, or more properly inter-space, is formed between the coffee bag and the sachet, thus leaving no room for air.
  • the said sachet -f- is made by a folded tubular film -9- with its ends -10- soldered, allowing for the required air-tightness, and the folded bag is tightly packed inside -d-.
  • the example shown can have modifications, both in the filter bag itself and in the capsule that protects the bag. Also, as a consequence of modifications in the shape of the bag, the half-compacted amount of coffee could have a not so spherical shape.
  • the key point is having the coffee in a ball-like form, independent of its exact external shape.
