Abstract

The capsule is made from a material which is impermeable to oxygen and water vapour and is designed to hold roast and ground coffee of which 5-15% of the fine particles are at least 90 mu m in size. The capsule is made from two identical layers of a supple material, circular, oval, or polygonal in shape, or with a round or truncated conical dome (11). It can be made, for example, from aluminium, plastics or a multilayered material, incorporating an oxygen-proof barrier of EVOH or PVDC (vinylidene polychloride), or paper and polyethylene, metallised polyester. Composite materials can also include polypropylene and polyamide.

Description

La présente invention concerne une enceinte fermée, contenant une substance pulvérulente pour la préparation d'une boisson choisie parmi le café torréfié et moulu, un mélange de café moulu et de café soluble, prévue pour être extraite sous pression, le matériau utilisé pour ladite enceinte est imperméable à l'oxygène et à la vapeur d'eau pour la conservation de ladite substance pulvérulente et ladite enceinte étant ouverte sous l'effet de la seule montée en pression lors de l'injection du fluide d'extraction.The present invention relates to a closed enclosure, containing a powdery substance for preparation a drink chosen from roasted and ground coffee, a mixture of ground coffee and soluble coffee, intended to be extracted under pressure, the material used for said enclosure is impermeable to oxygen and water vapor for the preservation of said pulverulent substance and said enclosure being opened under the effect of the sole pressure build-up during fluid injection extraction.

Il existe déjà de nombreux brevets mentionnant des capsules ou des cartouches prévues pour être extraites sous pression. On peut citer notamment la demande de brevet WO 94/01344 au nom de la demanderesse. Dans cette demande de brevet, il n'est fait aucune mention de la granulométrie de café torréfié et moulu utilisé : toute granulométrie est possible. Il peut arriver cependant que pour certaines raisons, il soit préférable de viser plus spécifiquement une certaine granulométrie.There are already many patents mentioning capsules or cartridges intended to be extracted under pressure. Mention may in particular be made of the patent application WO 94/01344 in the name of the plaintiff. In this request for patent, there is no mention of the particle size of roasted and ground coffee used: all grain sizes are possible. However, it may happen that for certain reasons, it is better to target more specifically a certain particle size.

Le but de la présente invention est de trouver une enceinte fermée, prévue pour l'extraction sous pression, dans laquelle on augmente la vitesse d'extraction , tout en garantissant un bon taux d'extraction de la substance pulvérulente utilisée.The object of the present invention is to find an enclosure closed, intended for pressure extraction, in which increases the extraction speed, while ensuring a good extraction rate of the substance powdery used.

L'invention concerne une enceinte fermée selon le préambule de la revendication 1, dans laquelle le café torréfié et moulu à une dimension particulaire telle qu'il comprend entre 5 et 15 % de fines ayant une taille de moins de 90 microns respectivement pour un D(4,3) compris entre 650 et 300 microns et il est compacté ou tassé.The invention relates to a closed enclosure according to the preamble of claim 1, wherein the roasted coffee and ground to a particle size as it includes between 5 and 15% of fines having a size of less than 90 microns respectively for a D (4.3) between 650 and 300 microns and it is compacted or packed.

Il existe plusieurs types de mouture possible dans le domaine du café. Le mouturage le plus répandu se fait avec des moulins avec rouleaux à cannelures axiales, comme par exemple un moulin de la Société Probat. On obtient des particules ayant une distribution granulométrique avec une teneur en fines plus élevée ( plus de 10 % de fines ayant une taille de moins de 90 microns pour un D(4,3) compris entre 650 et 300 microns). On envisage par conséquent de faire un mouturage pour obtenir des particules ayant une distribution granulométrique réduisant la teneur en fines. On arrive à ce résultat en faisant le mouturage sur des moulins avec rouleaux à cannelures radiales, comme par exemple un moulin de la Société Matsubo. On obtient une distribution en forme de gaussienne dans laquelle on a une diminution de la teneur en fines pour le D(4,3) tel que mentionné ci-dessus.There are several types of grind possible in the coffee field. The most widespread milling is done with mills with rollers with axial grooves, as per example a mill from the Company Probat. We get particles having a particle size distribution with a higher fines content (more than 10% of fines having a size of less than 90 microns for a D (4.3) included between 650 and 300 microns). We therefore plan to milling to obtain particles with a particle size distribution reducing the fines content. This is achieved by milling on mills with rollers with radial grooves, as per example a mill from the Matsubo Company. We get a Gaussian distribution in which we have a decrease in the fine content for D (4.3) such that mentioned above.

Par D(4,3) on entend la grandeur moyenne de particules basée sur leur diamètre selon le diagramme de Rosin Rammler.By D (4.3) we mean the average particle size based on their diameter according to the Rosin diagram Rammler.

Le café utilisé dans l'enceinte selon l'invention est compacté ou tassé. De ce fait,si on veut conserver une vitesse d'extraction assez élevée et un bon taux d'extraction, il devient avantageux de travailler avec une distribution granulométrique comme mentionnée dans la revendication 1. Par tassé, on entend une compression sous une pression de l'ordre du kg à quelques dizaines de kg/cm2. Par compacté, on entend une compression sous une pression de l'ordre de quelques centaines de kg/cm2.The coffee used in the enclosure according to the invention is compacted or packed. Therefore, if we want to keep a fairly high extraction speed and good rate extraction, it becomes advantageous to work with a particle size distribution as mentioned in the claim 1. Packed means a compression under a pressure of the order of kg to a few tens of kg / cm2. By compacted is meant compression under a pressure of the order of a few hundred kg / cm2.

La détermination de la taille des particules se fait avec un appareil Malvern Mastersizer-S avec une focale de 4 à 3500 microns, qui travaille avec un faisceau laser : on met en suspension butanolique les particules dont on veut déterminer la taille, on agite et on y fait passer un rayon laser. On étudie le faisceau réfléchi et le système de traitement de données conduit à une distribution statistique des tailles de particules.The determination of the particle size is done with a Malvern Mastersizer-S camera with a focal length of 4 to 3500 microns, which works with a laser beam: we put in butanolic suspension the particles we want determine the size, shake and pass a ray laser. We study the reflected beam and the data processing leads to distribution particle size statistics.

L'enceinte fermée selon l'invention peut être de deux types. La première solution consiste à envisager une capsule souple constituée de deux feuilles souples identiques de forme circulaire, ovale ou polygonale ménageant entre elles un espace pour la substance pulvérulente et soudées sur leur périphérie de manière à ce que ledit sachet soit sensiblement symétrique par rapport à son plan de soudage. La seconde solution consiste à envisager une cartouche comprenant une coupelle avec un fond et une paroi latérale ayant sensiblement la forme d'un tronc de cône ou d'un dôme et un rebord circulaire de diamètre supérieur au fond et un opercule soudé sur le pourtour du rebord de la capsule.The closed enclosure according to the invention can be two types. The first solution is to consider a flexible capsule consisting of two flexible sheets identical in circular, oval or polygonal shape providing space for substance between them pulverulent and welded on their periphery so that that said bag is substantially symmetrical with respect to his welding plan. The second solution is to consider a cartridge including a cup with a bottom and side wall having substantially the shape of a trunk of cone or dome and a circular rim of diameter greater than the bottom and a seal welded to the around the rim of the capsule.

Dans le cas de la seconde solution, la coupelle, de forme tronconique et de nature semi-rigide, peut être constituée d'aluminium d'une épaisseur de l'ordre de 20 à 100 microns, de plastique pur ou multi-couches avec éventuellement une couche barrière à l'oxygène telle que l'EVOH ou le PVDC, d'un film multi-couches tel que carton, aluminium, plastique ou carton, plastique avec éventuellement une couche barrière à l'oxygène telle que l'EVOH ou le PVDC. L'opercule de la capsule , de nature souple, peut être constitué d'aluminium d'une épaisseur de l'ordre de 15 à 60 microns, ou d'un film multi-couches comprenant soit du papier de 20 à 60 g/m2, du plastique tel que le PE d'une épaisseur de l'ordre de 20 à 60 microns et de l'aluminium d'une épaisseur de 5 à 20 microns, soit de l'EVOH ou du PVDC d'une épaisseur de 5 à 30 microns et du plastique (PP,PE, PA) de l'ordre de 20 à 100 microns, soit du PET (5 à 30 microns ) et du plastique (PP,PE) de 20 à 100 microns, soit du PET métallisé ou d'une couche haute barrière telle que SiO2.In the case of the second solution, the cup, of shape frustoconical and semi-rigid in nature, may be formed aluminum of the order of 20 to 100 microns, of pure plastic or multi-layer with possibly a oxygen barrier layer such as EVOH or PVDC, a multi-layer film such as cardboard, aluminum, plastic or cardboard, plastic with possibly a oxygen barrier layer such as EVOH or PVDC. The capsule seal, flexible in nature, can be made of aluminum of the order of 15 to 60 microns, or a multi-layer film comprising either paper from 20 to 60 g / m2, plastic such as PE from a thickness of the order of 20 to 60 microns and aluminum with a thickness of 5 to 20 microns, either EVOH or PVDC with a thickness of 5 to 30 microns and plastic (PP, PE, PA) of the order of 20 to 100 microns, i.e. PET (5 at 30 microns) and plastic (PP, PE) from 20 to 100 microns, either metallized PET or a high barrier layer such than SiO2.

Dans le cas de la première solution, les feuilles peuvent être faites de matériau souple tel que de l'aluminium d'une épaisseur de l'ordre de 5 à 40 microns ou du plastique tel que le PET. Préférentiellement les feuilles seront constitués d'un matériau multi-couche souple se prêtant au soudage par les méthodes usuelles tout en constituant une protection suffisante du produit face à l'oxygène et à la vapeur d'eau. La combinaison suivante de matériaux est recommandée :

  • couche extérieure : PET (normal,tissé, ou non tissé),PE, PP, PA, PS ou papier
  • couche centrale haute barrière : aluminium d'une épaisseur de l'ordre de 5 à 20 microns, EVOH, PVDC, PET ou PVA
  • couche intérieure : plastique, , de préférence PE ou PP ou OPP. On peut envisager les combinaisons multi-couches suivantes : PET-EVOH-PE ou PET-aluminium-PE.
    • In the case of the first solution, the sheets can be made of flexible material such as aluminum with a thickness of the order of 5 to 40 microns or plastic such as PET. Preferably, the sheets will be made of a flexible multi-layer material suitable for welding by the usual methods while constituting sufficient protection of the product against oxygen and water vapor. The following combination of materials is recommended:
  • outer layer: PET (normal, woven, or non-woven), PE, PP, PA, PS or paper
  • high barrier central layer: aluminum with a thickness of around 5 to 20 microns, EVOH, PVDC, PET or PVA
  • inner layer: plastic, preferably PE or PP or OPP. The following multi-layer combinations can be envisaged: PET-EVOH-PE or PET-aluminum-PE.

    • Pour la première et la seconde solution, le café est tassé ou compacté. De préférence, pour la première solution, le café est compacté et pour la seconde solution, il est tassé.For the first and second solution, the coffee is packed or compacted. Preferably, for the first solution, the coffee is compacted and for the second solution it is Cup.

    • Le but de la présente invention est d'avoir une capsule ou une cartouche prête à l'emploi, dans laquelle sur une base de contenance de 4 à 12 g de café torréfié et moulu, on arrive à obtenir une tasse de café de volume donné en moins de temps qu'avec une mouture Probat tout en maintenant le même taux d'extraction.The object of the present invention is to have a capsule or a ready-to-use cartridge, in which on a base with a capacity of 4 to 12 g of roasted and ground coffee, we manages to get a cup of coffee given less volume time with a Probat version while maintaining the same extraction rate.

    Pour ce faire, il faut limiter la teneur en fines. Ce résultat est atteint pour des enceintes contenant des fines selon la courbe C de la figure 1. Cette granulométrie est obtenue avec un moulin Matsubo. En abscisse, on représente le D(4,3), c'est-à-dire la taille moyenne des particules en microns : chaque point correspond à une mouture. En ordonnées, on représente la teneur en fines, c'est-à-dire la teneur en particules ayant une dimension inférieure à 90 microns. A titre de comparaison, on voit sur la courbe D la distribution granulométrique avec un moulin Probat : Pour des valeurs de D(4,3) identiques, on a une teneur en fines plus élevée.To do this, the fines content must be limited. This result is achieved for enclosures containing fines according to curve C in FIG. 1. This particle size is obtained with a Matsubo mill. On the abscissa, we represent D (4.3), that is to say the average particle size in microns: each point corresponds to a grind. In ordinates, we represent the fine content, i.e. the content of particles having a dimension less than 90 microns. For comparison, we see on curve D the particle size distribution with a Probat mill: For identical values of D (4,3), we have a fine content higher.

    La figure 2 représente d'une part la répartition granulométrique à partir d'une échelle logarithmique en abscisse : c'est la gaussienne A, l'ordonnée de gauche indiquant la teneur en % pour chaque granulométrie. On voit bien le maximum à 410 microns et la taille moyenne de particules D(4,3) est de 383 microns.Figure 2 shows on the one hand the distribution particle size from a logarithmic scale in abscissa: it is the Gaussian A, the ordinate on the left indicating the content in% for each particle size. We see well the maximum at 410 microns and the average size of particle D (4.3) is 383 microns.

    La courbe B somme les différentes granulométries pour passer de 0 à 100 % : ordonnée de droite.Curve B sums the different particle sizes for go from 0 to 100%: ordinate on the right.

    A titre de comparaison, le figure 3 montre la même répartition granulométrique, mais avec un moulin Probat. La courbe E indique la gaussienne à la même échelle que la figure précédente, d'où il ressort bien la teneur plus élevée en fines. La courbe F somme les différentes granulométries et si on compare avec la courbe B, on voit bien une teneur plus élevée à 100 microns. Dans ce cas, sur la courbe E, le maximum est à 409 microns et le D(4,3) à 380 microns.For comparison, Figure 3 shows the same particle size distribution, but with a Probat mill. The curve E indicates the Gaussian on the same scale as the previous figure, which clearly shows the content more high in fines. Curve F sums the different grain sizes and if we compare with curve B, we see although a higher content at 100 microns. In this case, on curve E, the maximum is at 409 microns and the D (4.3) at 380 microns.

    La figure 4 montre une capsule souple contenant du café torréfié et moulu avec les granulométries selon les figures 1 (C) et 2 ci-dessus. Le sachet (1) de forme circulaire comporte deux feuilles de matière souple (2) et (3) soudées sur leur périphérie (4) par thermoscellage et contenant du café torréfié moulu (5) compacté pour la préparation d'une boisson. La café compacté présente des faces convexes (35), la forme générale de sa section étant circulaire , ainsi que celle du sachet. Le flan cylindrique (38) de la galette a pour but d'éviter la présence indésirable de grains dans la zone de soudage.Figure 4 shows a soft capsule containing coffee roasted and ground with the grain sizes according to the figures 1 (C) and 2 above. The bag (1) of circular shape has two sheets of flexible material (2) and (3) welded on their periphery (4) by heat sealing and containing ground roasted coffee (5) compacted for the preparation of a drink. The compacted coffee has convex faces (35), the general shape of its section being circular, thus than that of the bag. The cylindrical blank (38) of the wafer is intended to avoid the undesirable presence of grains in the welding area.

    S'agissant de la figure 5, la cartouche (11) comporte une coupelle (12) avec un fond (15) et une paroi latérale de forme tronconique (16). La coupelle est en aluminium d'épaisseur 50 microns. La cartouche contient du café torréfié (13) et elle est fermée par un opercule (14) en composite aluminium/papier. Cet opercule est soudé sur le pourtour (17) de rebord de la coupelle. With regard to FIG. 5, the cartridge (11) has a cup (12) with a bottom (15) and a side wall of frustoconical shape (16). The cup is made of aluminum 50 microns thick.

    Exemples 1 à 3Examples 1 to 3

    On effectue les essais avec une capsule selon la figure 4 contenant successivement 4,6 , 5 et 5,2 g de café torréfié et moulu ayant un D(4,3) de 355 microns.The tests are carried out with a capsule according to FIG. 4 successively containing 4.6, 5 and 5.2 g of roasted coffee and ground having a D (4.3) of 355 microns.

    On fait une extraction sur une machine selon la demande de brevet WO 94/02059. On prépare une tasse de café de 50 g. Pour la première capsule, on obtient la tasse en 22 secondes avec une mouture Matsubo, alors qu'il faut 28 sec. pour obtenir la même quantité avec une mouture Probat. Si on regarde maintenant le taux d'extraction, on constate qu'ils sont identiques.We do an extraction on a machine according to the request of WO 94/02059. We prepare a 50 g cup of coffee. For the first capsule, we obtain the cup in 22 seconds with a Matsubo grind, while it takes 28 sec. to obtain the same quantity with a Probat grind. Yes we now look at the extraction rate, we see that they are identical.

    Pour la capsule de 5 g, avec la mouture selon l'invention, on obtient une tasse de 50 g en 21 sec. alors qu'avec une mouture Probat il faut 24 secondes.Là également, les taux d'extraction sont identiques.For the 5 g capsule, with the grind according to the invention, a cup of 50 g is obtained in 21 sec. whereas with a Probat grinding takes 24 seconds. Also, the rates are identical.

    Finalement, pour la capsule de 5,2 g, on obtient en 20 sec. une tasse de café de 50 g avec une mouture selon l'invention, alors qu'il faut 26 sec. avec du café à mouture Probat. Les taux d'extraction sont toujours identiques.Finally, for the 5.2 g capsule, we obtain in 20 sec. a 50 g cup of coffee with ground coffee the invention, while it takes 26 sec. with coffee at Probat version. Extraction rates are still identical.

    On arrive donc à obtenir avec une enceinte selon l'invention une extraction plus rapide du café. So we get to get with a speaker according the invention a faster extraction of coffee.
