  • the package strip comprises half-cavities sealed together around each cavity, aiming to encapsulate in a tight manner beverage precursors (pearls) into the cavities.
  • each package 30; 40 encloses one portion of food or beverage precursor.
  • Each portion may contain a few grams of food or beverage precursors, for example, in the case of a beverage precursor, 5 to 6 grams, corresponding to at least one serving of beverage.
  • the beverage precursor is preferably a compacted beverage precursor made of compacted powder.
  • the beverage precursor contains essentially roast-and-ground coffee.
  • the beverage precursor may also comprise a mix of roast-and-ground coffee and soluble coffee or a mix of roast-and ground coffee and milk powder.
  • the beverage precursor may also comprise soluble coffee, milk powder or a chocolate based compacted powder.
  • one portion may be suitable for preparing one cup of coffee.
  • the portions are preferably spherical.
  • the term “spherical” encompasses also designs such as multiple facets (e.g. like a "football” shape) or a sphere having truncated faces of diameter less than the diameter of the sphere or slightly ovoid or oval or egg shapes.
  • a preferred shape is however a ball with circular cross-sections.
  • an inner nominal diameter of one cavity is comprised between 22 mm and 25 mm, for example here about 23.3 mm which corresponds to the outer nominal diameter of the packed portion.
  • Packages 30, 40 are bonded together in order to create the full strip, as shown in figures 4 and 5 .
  • packages 30 and 40 are closed (after insertion of a beverage precursor portion) and linked to each other, either as illustrated in figure 2 or in figure 3 .
  • the method may also comprise a step of cutting an edge along at least one side of the packages 30, 40.
  • a cutting footprint of the package strip corresponds to a "wave" shape which helps to save the material usage and to ensure a good-looking aspect of the packaging.

  • a shell can comprise a flange which comprises ring 13_1 and one tab 13_2 extending from the ring, or even a ring 13_1 with two tabs 13_2, for example diametrically aligned one to the other, for example along a longitudinal direction of the strip once the shell is assembled to a complementary shell to form a package.
  • the tabs should be aligned, one to the other, within a tolerance of angle of less than 1°, preferably less than 0.5°.
  • Figure 7 shows a possible assembling of a first shell 10_1 with a first complementary shell 14_1 before assembling with a second shell 20_3.
  • first shell 10_1 with a first complementary shell 14_1 before assembling with a second shell 20_3.
  • first complementary shell 14_1 before assembling with a second shell 20_3.
  • the package strip may comprise a closing strip comprising at least the second part of the first cavity and the second part of the second cavity.
  • the cavities of such a closing strip can be flatter, so that they can be more easily formed in a strip although they are made of paper-based material.
  • the packages may have a flatter shape, for example a half sphere shape.
  • Figure 8 shows a package strip 100 comprising tens of packages 30, 40 as described above.
  • a package strip 100 as described above can be easily wound in superimposed layers, with the portions of one package 30, 40 arranged in quincunx between two adjacent layers of the package strip 100.
  • the distance d between two neighboring packages 30, 40 may be larger than a diameter of one cavity, so that a folding of two layers is eased.
  • Such wound package strip 100 can then be packed in a casing 200 as diagrammatically shown in Figure 9 .
  • the casing 200 is generally made of a paper-based material.
  • the casing 200 may be shaped as a box with an overall parallelepipedal form. For example, it has a narrow rectangular bottom and top, two large side walls and narrower front and rear walls.
  • the casing 200 may optionally comprise a transparent window provided on at least one of the large sidewall and/or top to enable to visualize the band of portions inside.
  • the casing 200 may further comprise at least one openable gate which forms an opening for allowing the package strip to be progressively withdrawn from the casing during dispensing, e.g. delayered or unwound, with one portion at a time.
  • the openable gate may be positioned in a corner or nearby, said top front corner of the casing 200.
  • Figure 10 shows an example embodiment of a food or beverage preparation apparatus 300.
  • Such apparatus may be mainly as one described in WO 2019/219523 or WO 2019/219524 .
  • the apparatus comprises a seat to receive a casing 200 as described in connection with figure 9 , with the opening of the casing close to a portion removing assembly of the apparatus.
  • the portion removing assembly preferably comprises a portion capturing rotary drum 301 driven in rotation in a stepwise fashion by a driving assembly.
  • the portion capturing rotary drum comprises a plurality of receiving holes 302 formed in an outer annular wall 303 of the drum 301.
  • the receiving holes 302 are individually dimensioned and arranged at distance one another so as to match with the distance d between neighboring packages 30, 40 of the package strip 100.
  • the package strip 100 is progressively withdrawn from the casing 200.
  • the apparatus 300 further comprises package opening means 304 such as a cutting tool arranged for opening the cavities of one package by cutting along one cutting line in at least one side of one package to remove each portion individually.
  • the cutting tool may be driven by a linear motorized actuator configured for moving the cutting tool reciprocally between a retracted position and a cutting position.
  • the cutting tool may be formed as a cylinder of diameter slightly larger than the diameter of one beverage portion and may comprise at least one blade arranged circumferentially on the free edge of the cylinder.
  • the cutting tool is arranged to cut the strip 100 on at least 200° or preferably between 300 and 340° about the portion to provide sufficient opening of the cavity and facilitate ejection of the portion while keeping the package material in one piece.
  • the apparatus 300 may further comprise portion ejection means 305 for expulsing the portion from the cavity after the package is cut open.
  • the portion ejection means 305 may take various forms.
  • the portion ejection means 305 comprises a cam which is stationary arranged on an internal bearing which is arranged co-centrically relative to the rotary drum 301.
  • the cam is preferably positioned angularly, e.g. an angle of 50-80 degrees after the cutting tool, to push the portion outside the corresponding cavity as the drum 301 rotates (as illustrated in Figure 10 in clockwise direction R).
  • the apparatus 300 may further comprise a chute or the like, arranged for gently receiving and transporting by gravity or otherwise (e.g. air pressure), the portion to a food or beverage preparation device to prepare the food or beverage.
  • a chute or the like arranged for gently receiving and transporting by gravity or otherwise (e.g. air pressure), the portion to a food or beverage preparation device to prepare the food or beverage.
  • the apparatus 300 preferably comprises at least one container to receive the used package material on one side and the organic residue (food or beverage precursor portion after use) on another side, which eases recycling and composting of waste.
