Definitions

  • the present invention relates to a disposable cartridge comprising a substantially rigid casing which contains a portion of powder, granular or like particulate material for producing a drink by percolation, dissolution or infusion with hot water under pressure, in which the casing comprises a substantially cylindrical hollow body which includes an imperforate side wall, an inlet end wall having a perforated central region and a perforated opposite outlet end wall, and in which the inlet end wall has a compressible outer peripheral annular rib made from plastics material, which surrounds the perforated region and can be engaged under mechanical pressure by a heated plate for introducing hot water under hydraulic pressure into the cartridge through the said central region to produce the drink and dispense it through the outlet end wall.
  • Cartridges of this general type are known from document FR-A-2 041 380.
  • the peripheral annular rib serves as a kind of seal cooperating with the delivery outlet plate of the machine so as peripherally to contain the hot water under pressure which is introduced into the cartridge through the perforated region of its upper wall from the centre of the delivery plate.
  • the plate should press on the annular rib and couple with this in a precise manner to prevent hot water from leaking peripherally before reaching the interior of the cartridge.
  • the object of the present invention is to provide a cartridge of the type discussed above in which a perfect sealing coupling between the plate and the annular rib will be guaranteed even in the event that the two parts are not coplanar.
  • this object is achieved by means of a cartridge of the type described above, characterised in that the said annular rib is made from a plastics material having a softening point less than the temperature of boiling water and a melting point greater than that of boiling water such that the rib is partially softenable and deformable under the mechanical pressure exerted by the heated plate (P).
  • the rib has an annular crest which can be flattened under the mechanical pressure of the delivery plate after softening of the plastics material.
  • the rib has a frusto-conical face the vertex of which coincides with the axis of the cartridge and which has an obtuse vertex angle, as well as a radially outer surface forming, with the frusto-conical face, the said flattenable annular crest.
  • the face of the rib has a very shallow inclination towards the centre of the upper wall: gradually as the annular crest softens the plate is able to press on a surface of the rib which rapidly grows as the plate descends and with a corresponding rapid reduction in the specific mechanical pressure on the upper surface of the rib.
  • This reduction in specific pressure corresponds a gradually decreasing softening of the plastics material, and deformation of the rib is finally stopped without the rib becoming entirely softened.
  • a disposable cartridge comprises a hollow body or casing, generally indicated 10.
  • the hollow body 10 has a substantially cylindrical form and is able to contain a portion of a granular, powder or particulate material M (Figure 2) able to produce a drink by percolation, dissolution or infusion with hot water under pressure.
  • Figure 2 a granular, powder or particulate material M
  • Figure 2 able to produce a drink by percolation, dissolution or infusion with hot water under pressure.
  • the hollow body 10 includes a cup-shaped part, generally indicated 12, and a part constituting a cover, generally indicated 14. Both the parts 12 and 14 can be made economically in substantially rigid plastics material suitable for use with foods. The use of a plastics material is not however limitative except for the characteristics which will be described further below.
  • a convenient material for producing the parts 12 and 14 is a polypropylene which, in order to achieve the objects of the invention which will be discussed, has a softening temperature around 100°C.
  • the cup-shaped part 12 includes an imperforate substantially cylindrical side wall 16 which constitutes the side wall of the casing 10, and a bottom wall 18 which constitutes an outlet end wall of the casing 10.
  • the bottom wall 18 is surrounded by an annular rib 19 which serves to form a seal on a lower plate or like element on which the cartridge can be supported by its lower wall.
  • the bottom wall 18 is perforated and can have a plurality of holes, as illustrated for example in document EP-A-0 041 931, or a single central hole, as described and illustrated in document EP-A-0 057 671.
  • the cover 14 includes a perforated circular central region 20 which constitutes an inlet end wall of the casing 10.
  • the central region 20 is surrounded outwardly by a peripheral annular flange 22 coupled to a corresponding annular flange 24 formed integrally with the upper edge of the side wall 16 of the cup-shaped part 12.
  • the central region 20 can have a plurality of holes, as shown, or other apertures, or one or more peripheral holes as in document EP-A-0 057 671 to which reference is made.
  • the outer peripheral annular rib 26 which surrounds the perforated central region 20 of the inlet end wall has a frusto-conical face 28 the vertex of which is coincident with the axis of the cartridge.
  • the vertex angle of the frusto-conical face 28 is obtuse. This vertex angle is preferably almost flat, with a value of the order of 175°.
  • the annular rib 26 is delimited by a radially outer surface 30 which forms, with the frusto conical face 28, a circular crest or annular apex 32.
  • a radially outer surface 30 which forms, with the frusto conical face 28, a circular crest or annular apex 32.
  • the front face 28 and radially outer face 30 form between them an angle equal to about 90°.
  • a preferred material at least for the rib 26 and preferably for the whole of the body 10 is a food grade polypropylene having a softening point slightly less than the temperature of boiling water, but a melting point higher than the temperature of boiling water (for example 110°C).
  • the reference letter P indicates a metal plate which forms part of a coffee machine or other machine for the extraction of a drink starting from the material M ( Figure 2) contained in the cartridge.
  • the machine can be of the type described and illustrated in document EP-A-0 041 931.
  • the plate P has a central hole for the delivery of hot water, for example at a temperature of 90°C and at a pressure between 1 and 1,5 MPa (10 and 15 bar respectively).
  • the plate P For delivery of hot water under pressure the plate P has been lowered or otherwise pressed in the direction of the arrow F onto the annular rib 26.
  • the temperature of the plate P is substantially equal to that of the hot water, that is to say of the order of 90°C.
  • the plate P Under the mechanical pressure exerted in the direction of the arrow F the plate P has softened and deformed first the annular apex 32 and then, partially, the upper part of the rib 26.
  • reference numeral 26a represents the integral part of the rib 26 before softening and the reference 26b indicates the bulge deriving from the softened part 28a underlying the apex 32.
  • the flat pressure surface S of the plate P has largely transformed the initially frusto-conical face 28 into a flat face 28a which seals against the surface S of the plate P thus guaranteeing an hermetic seal against the escape of hot water under pressure from the space, indicated 32, lying between the perforated central region 20 of the cover 14 and the corresponding central region of the plate P.
  • the plastics material of the annular rib 26, softened and deformed under the effect of the heat does not melt due to the fact that its temperature does not exceed about 100°C which is the temperature of the water introduced into the cartridge. It remains in what may be called a "rubbery" state and in this state behaves practically as a resilient seal to the advantage of the sealing effect.
