Definitions

  • the present invention relates to a disposable capsule designed for use in machines for the preparation of liquid products, such as hot beverages, of the type normally used in offices or public places in general, but also in private dwellings.
  • a first type of capsules envisages a sealed body, containing a dose of a substance that can form a liquid product via water and/or steam; said substance is typically in granular, powdered, or fragmented form, such as, for example, ground coffee.
  • the capsule basically consists of a body made of thermoplastic material compatible for alimentary uses, in the form of a frustoconical cup, containing the aforesaid dose of substance and closed at the top by a sealing membrane (see, for example, IT 1250066 B).
  • the bottom of the plastic body and the sealing membrane are perforated or torn, possibly at different moments, by means of purposely provided members of the automatic machine in the course of preparation of the liquid product; in this way, there is enabled injection of hot water and/or steam under pressure into the capsule and subsequent outflow therefrom of the product resulting from mixing (by infusion or percolation) of the injected fluid and the substance.
  • the capsule is not sealed (see, for example, IT 1256690 B and IT 1307241 B).
  • the plastic body of the capsule has a substantially cylindrical peripheral wall and a perforated bottom, which define the cavity designed to receive the dose of substance, the body being closed at the top by means permeable to water and/or steam, typically comprising a perforated plastic wall and/or a filtering element made of paper or fabric.
  • the corresponding automatic machines do not need to have perforation members: water and/or steam can be introduced freely through the aforesaid permeable means, and the liquid product obtained can flow off through the holes pre-formed in the bottom of the capsule.
  • the through holes preformed in the bottom of these capsules generally have a frusto-pyramidal shape and are arranged according to a grid pattern, where the array of holes covers the bottom of the capsule substantially throughout its extension.
  • the peripheral wall of the body of a capsule of a perforated type is substantially cylindrical or, more precisely, only slightly frusto- conical; the inclination of the peripheral wall is in fact very modest and basically has the purpose of enabling, in the production step, extraction of the plastic body of the capsule from the corresponding mould.
  • the peripheral wall of the body of the capsule has a basically constant cross section so that also the cavity inside the capsule, where the precursor dose of the liquid product is present, is substantially cylindrical.
  • the present invention basically has the purpose of providing a capsule of a perforated type, i.e., of the second type referred to above, in an improved embodiment as compared with the prior art.
  • an object of the present invention is to provide a capsule of the type referred to above, designed to improve the process of mixing - by infusion or percolation - between water and/or steam introduced under pressure in the capsule and the dose of substance contained therein.
  • Another object of the invention is to provide a capsule of increased strength as compared to those of the known art.
  • Yet another object of the invention is to provide a capsule of the above sort that can be produced with a contained amount of plastic material.
  • FIG. 1 is a perspective view of a capsule according to the present invention from the underside thereof;
  • FIG. 2 is a perspective view according to the arrow II of Figure 1 ;
  • FIG. 3 is a top plan view according to the arrow III of Figure 1 ;

  • phrases such as “in an embodiment” or “in one embodiment” and the like that may be present in various points of the present description do not necessarily all refer to one and the same embodiment.
  • the particular configurations, structures, or characteristics can be combined in any adequate way in one or more embodiments.
  • the references used in what follows are merely for convenience and do not define the sphere of protection or the scope of the embodiments.
  • the capsule 1 comprises a generally cuplike body 2, having a longitudinal axis designated by X in Figures 5 and 6.
  • the body 2 includes a peripheral wall 3, a perforated bottom 4 in the proximity of or at a first axial end 5 of the wall 3, and a collar 6 integral with a second axial end 7 of the wall 3.
  • the body 2, which defines in a single piece the wall 3, the bottom 4, and the collar 6, is made of plastic material compatible for alimentary uses, for example, polypropylene that can be injection moulded with a shrinkage of approximately 1.8%.
  • the perforated bottom 4 is in the proximity of the end 5 in order to define, together with the wall 3, a first spatial region and a second spatial region separated by means of the bottom 4 itself.
  • the first spatial region is a volume or cavity V ( Figures 2 and 4-6), axially comprised between the bottom 4 and the second axial end 7, for housing a dose of substance that can form a liquid product with water and/or steam, such as a granular, powdered, or fragmented substance.
  • Said substance is not represented in the figures for reasons of greater clarity: it is assumed here that said substance is ground coffee.
  • the second spatial region is a disk-shaped recess 8 located in which is a plurality of ribs 9 integral with the bottom 4.
  • the ribs 9 have a radial orientation, are set at equal angular distances apart, and converge on an axial projection 10, which is also integral with the bottom 4 and situated in the disk-shaped recess 8.
  • the axial projection 11 is disk-shaped, shares the axis X, and comprises a preferably spherical and concave axial contrast surface 11.

  • the stretch 13 also has a thickness progressively decreasing towards the axial projection 10.
  • the entire top edge of the ribs 9 could be inclined with respect to the bottom 4 and converge on the axial projection 10.

  • Said closing element of a type permeable to water and/or steam, can be of any type known in the sector, for example, comprising a wall or film of perforated plastic material and/or a film of paper or fabric for filters; the element 15, or at least one of the parts that makes it up, can be fixed to the collar 6, for example, via heat-sealing or gluing.
  • the collar 6 can be provided in at least two variants.
  • the collar 6 includes a portion of wall that is radially separated from the wall 3 by a circumferential groove, divided into a plurality of compartments by radial diaphragms, which are not indicated but may be clearly seen in Figure 3.
  • This solution enables reduction of the amount of plastic material necessary for formation of the collar, at the same time guaranteeing an adequate structural strength thereof.
  • the collar 6 can be configured as a massive annular element, without compartments or cavities.
  • the bottom 4 comprises a plurality of through holes 18, divided into a number of distinct arrays or sets, preferably having a frusto-conical shape flared outwards and provided only in the sectors 12.

  • the holes of the bottom have a grid pattern. It has been found that said grid pattern is not exactly compatible, from the geometrical standpoint, with the arrangement of the corresponding ribs. In fact, the latter have a radial orientation that, superimposed on the arrangement of the holes of the grid, can create local lack of uniformity of the area of passage. In practice, one or more holes can be partially obstructed by the presence of one of the ribs or be immediately adjacent thereto, with consequent variation of the local conditions of outflow.
  • each set 19 is arranged on mutually concentric circumferences having radiuses preferably increasing with constant increments from a minimum radius to a maximum radius.
