Definitions

  • the present invention relates to an apparatus for making or preparing one or more consumption units of a hot beverage, in particular coffee, comprising a combination of a filter pan and a disposable filter cartridge with filters of fibrous web material fitting therein, with the filter pan and the filter cartridge being provided with coacting walls which ensure a water seal between the said portions when the filter cartridge has been introduced into the filter pan and water is being infused.
  • a major drawback of the known apparatus is that for obtaining the desired capillary effect, a very close tolerance of the cartridge and the filter pan is required.
  • it is also known to effect the combination in such a manner that the filter cartridge has to be pushed into the filter pan with some force, however, with the risk of damaging the top filter, as well as of soiling one's fingers upon removal of the cartridge after use.
  • the apparatus is characterized to that end in that the filter pan and the filter cartridge are made of materials having different coefficients of expansion and the portions coacting for sealing purposes are dimensioned in such a manner that, on insertion of the filter cartridge, it rests without clamping or loosely in the cartridge and the water seal is obtained by means of capillary forces and/or clamping occurring during the infusion of the hot water owing to the difference in coefficients of expansion.
  • the filter cartridge can have a larger tolerance relative to the filter pan than is the case in the known construction, for either by the capillary effect or by clamping or both, a water seal is obtained between the filter pan and the cartridge.
  • the cartridge will have a loose position in the filter pan at ambient temperature, so that said pan can be removed without manual contact.
  • the disposable filter cartridge should be made of a material having a larger coefficient of expansion that that of the filter pan material.
  • An example of a suitable combination is a filter pan of aluminum and a disposable filter cartridge of polypropylene.
  • the filter cartridge and the filter pan are conical and that the angle between said conical side walls and the axis of the cartridge is 3-10°, preferably 6°.
  • a filter pan 1 partly shown accommodates a disposable filter cartridge 2. Since such a filter pan and cartridge are known per se (see e.g. Dutch patent application 83.00213 , mentioned in the introduction), these will not be further described hereinafter.
  • Fig. 1b shows the situation after the infusion of hot water, so that the pan and cartridge are expanded, on the understanding that as a result of the larger coefficient of expansion of the cartridge, this now rests clampingly in the filter pan.
  • Fig. 2a shows a combination of cartridge and pan at ambient temperature with a considerably larger clearance being present than in the assembly shown in Fig. 1a.
  • Fig. 2b After infusion of hot water, in the combination shown in Fig. 2a, the situation shown in Fig. 2b will occur, wherein the clearance between the coacting walls of the filter pan and the cartridge is substantially reduced. It is true that as a result, there will be no clamping effect, but the clearance between the said walls has become of such a nature that a water seal is obtained through capillary forces.
  • FIG. 3 and 4 shows a filter cartridge 3 received in a filter pan 4, wherein the cartridge does not rest with an upper peripheral edge on the pan, as in the embodiments shown in Figs. 1 and 2, but wherein the cartridge 3 with its inclined side wall 5 (Fig. 3 left hand part) rests on the corre­sponding side wall 6 of pan 4.
  • Figs. 3 and 4 shows a filter cartridge with a given unroundness: the cartridge has such a position in the filter pan that this is clampingly received in the pan in the places indicated at 7, while in the places indicated at 8, there is provided such a space between the said edges that this produces a capillary seal only after infusion of hot water due to expansion in the above places. In this manner, leakage will be prevented even in the case of unroundness.
  • a filter pan of aluminum and a filter cartridge of polypropylene may also consist of e.g. a filter cartridge of polypropylene (coefficient of expansion 0.0015 mm/mm/°C) and a filter pan of polystyrene (coefficient of expansion 0.0008 mm/mm/°C) or a filter cartridge of polypropylene or polystyrene and a filter pan of polycarbonate (coefficient of expansion 0.0007 mm/mm/°C).
  • a filter pan 11 shown only partly is provided with a conically bulged portion 12 wherein fits a filter cartridge 13 having a conical peripheral wall 14.
  • the angle between the conical wall and the vertical is indicated at ⁇ .
  • the materials used will be of influence for the filter cartridge or the filter pan.
