Abstract
Description
Procéde de conditionnement pour le café. Conditioning process for coffee.
La présente invention concerne un procédé de conditionnement pour le café. The present invention relates to a packaging method for coffee.
Il est connu d'employer pour faire du café des filtres en papier poreux, en forme de tronc de cône aplati, dont la partie inférieure a la forme d'un trapèze et dont la partie supérieure est arrondie en arc de cercle ; les trois côtés du trapèze sont fermés, alors que la partie supérieure incurvée est ouverte. It is known to use filters for making coffee from porous paper, in the form of a flattened truncated cone, the lower part of which has the shape of a trapezoid and the upper part of which is rounded in an arc of a circle; the three sides of the trapezoid are closed, while the upper curved part is open.
Pour faire du café on ouvre le filtre en écartant l'un de l'autre les deux rebords supérieurs incurvés; puis on place le filtre ainsi ouvert dans un support perforé placé sur une cafetière et on verse de l'eau bouillante sur le café. To make coffee, the filter is opened by spreading the two curved upper edges from each other; then place the filter thus opened in a perforated support placed on a coffee maker and pour boiling water on the coffee.
L'inconvénient de ce genre de filtre est que le café préalablement moulu s'évente et de surcroît l'utilisateur a tendance à mettre toujours un peu trop de café dans le filtre, ce qui, lorsque l'on fait quotidiennement du café, finit par se traduire par une consommation excessive de cafe et un changement de goût. The disadvantage of this kind of filter is that the previously ground coffee fades and in addition the user tends to always put a little too much coffee in the filter, which, when making coffee daily, ends up by resulting in excessive consumption of coffee and a change in taste.
Pour améliorer la qualité du café, on a proposé dans le certificat d'addition 71.08130 au brevet français 1.534.274 de placer un tel filtre, préalablement rempli d'une dose de café déterminée, dans un emballage étanche, pouvant être déformé, mais gardant sa forme, par exemple en feuille d'aluminium, cet emballage ayant une forme analogue à celle du filtre, tout en étant legerement plus grande et en ayant un rebord supérieur rectiligne. Selon ce brevet cet emballage est mis sous vide, ce qui permet de mieux conserver la substance tout en la compactant afin d'éviter qu'elle ne se répande dans l'enveloppe.Au moment de l'emploi, il suffit de découper le haut et le bas de l'enveloppe et de l'ouvrir pour que cette enveloppe relativement rigide constitue elle-meme le support de filtre que l'on place au-dessus de la cafetière. On supprime ainsi, à la fois le surdosage et la perte de fraîcheur du café. Cependant cet emballage est d'une mise en oeuvre complexe à la fois au niveau du conditionnement, et au niveau de l'utilisateur, de sorte que cette disposition n'a connu qu'un succès commercial pratiquement limité à son emploi pour le camping, cette enveloppesupport pouvant se placer sur n'importe quel genre de récipient. To improve the quality of coffee, it has been proposed in the certificate of addition 71.08130 to French patent 1,534,274 to place such a filter, previously filled with a determined dose of coffee, in a sealed packaging, which can be deformed, but keeping its shape, for example aluminum foil, this packaging having a shape similar to that of the filter, while being slightly larger and having a rectilinear upper rim. According to this patent, this packaging is placed under vacuum, which makes it possible to better conserve the substance while compacting it in order to prevent it from spreading in the envelope. At the time of use, it suffices to cut the top and the bottom of the envelope and open it so that this relatively rigid envelope itself constitutes the filter support that is placed above the coffee maker. This eliminates both the overdose and the loss of freshness of the coffee. However, this packaging is of complex implementation both at the packaging level and at the user level, so that this arrangement has known only commercial success practically limited to its use for camping, this envelopesupport can be placed on any kind of container.
La présente invention a pour objet de réaliser de façon simple et commode un emballage sous vide pré-dosé. The object of the present invention is to provide a simple and convenient pre-dosed vacuum packaging.
Le procéde de conditionnement sous vide selon l'invention est caractérisé par le fait que : on utilise un filtre de type connu, c'est-à-dire un filtre en papier poreux comportant trois côtés fermes en forme de trapèze et un côté ouvert, on met dans ce filtre la quantité de café moulu correspondant à un nombre déterminé de tasses ; on replie sur lui-même ie rebord incurvé dudit filtre ; on procède à un gaufrage dudit rebord ainsi replié afin de fermer le filtre ; et on place le filtre ainsi rempli et fermé dans un emballage sous vide usuel. Lorsqu'on veut faire du café, il suffit d'ouvrir l'emballage de le jeter puis, en saisissant les deux rebords repliés du filtre, d'ouvrir ce dernier et de le placer dans le support usuel de filtre.Le conditionnement du café en dose préparé à l'avance est ainsi beaucoup plus simple ce qui signifie beaucoup moins cher, et son emploi par l'utilisateur est également beaucoup plus simple. The vacuum packaging method according to the invention is characterized in that: a filter of known type is used, that is to say a porous paper filter comprising three firm sides in the shape of a trapezoid and one open side, the quantity of ground coffee corresponding to a determined number of cups is placed in this filter; the curved edge of said filter is folded back on itself; embossing said rim thus folded in order to close the filter; and the filter thus filled and closed is placed in a usual vacuum packaging. When you want to make coffee, you just need to open the packaging and throw it away, then, by grasping the two folded edges of the filter, open the filter and place it in the usual filter holder. in dose prepared in advance is thus much simpler which means much less expensive, and its use by the user is also much simpler.
L'invention couvre également à titre de produit nouveau. le produit obtenu par le procédé exposé précédemment. The invention also covers as a new product. the product obtained by the process described above.
On peut disposer un seul filtre dans un emballage, mais on peut également en disposer plusieurs et dans ce cas, on sépare l'emballage en autant de compartiments indépendants qu'il y a de filtres, afin que chaque filtre non utilisé demeure sous vide. You can have a single filter in one package, but you can also have several, and in this case, separate the package into as many independent compartments as there are filters, so that each unused filter remains under vacuum.
A titre d'exemple et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés
Figure 1, une vue en perspective d'un exemple de réalisation de l'invention;
Figure 2, une vue en élévation latérale du filtre de la figure 1;
Figure 3, une vue en pian illustrant un filtre dans un emballage sous vide;
Figure 4, une vue en pian illustrant un emballage comportant deux filtres.By way of example and to facilitate understanding of the invention, there is shown in the accompanying drawings
Figure 1, a perspective view of an exemplary embodiment of the invention;
Figure 2, a side elevational view of the filter of Figure 1;
Figure 3, a plan view illustrating a filter in a vacuum package;
Figure 4, a plan view illustrating a package with two filters.
La figure 1 représente un filtre en papier poreux 1
Comme cela est connu, ce filtre, lorsqu'il est à plat, comme représenté sur la figure, a la forme d'un trapèze dont la grande base est arrondie, mais, lorsqu'il est ouvert, il se présente sous la forme d'un tronc de cône dont l'extrémité est aplatie ; comme cela et egaiement connu, le rebord supérieur de ce filtre est incurvé comme représenté en 2, les deux lèvres du filtre étant appuyées l'une contre l'autre ; alors que les trois autres côtés sont fermés.Figure 1 shows a porous paper filter 1
As is known, this filter, when it is flat, as shown in the figure, has the shape of a trapezoid whose large base is rounded, but, when open, it comes in the form of 'a truncated cone whose end is flattened; like this and also known, the upper edge of this filter is curved as shown in 2, the two lips of the filter being pressed one against the other; while the other three sides are closed.
Selon la présente invention, on remplit le filtre de café moulu, en y mettant une quantité de café, correspondant à un nombre de tasses déterminé; puis on ferme le filtre en repliant les deux rebords, comme cela est représenté en traits pleins sur la figure 1 et comme cela est représenté à la figure 2 ; puis pour maintenir le filtre fermé, on procède à un gaufrage des rebords repliés le long de la iigne de pliage, comme cela est représenté, en 3, aux figures 1 et 2. Le filtre ainsi pré-dosé et fermé est ensuite placé dans un emballage sous vide 4, comme représenté à la figure 3. According to the present invention, the filter is filled with ground coffee, by putting a quantity of coffee therein, corresponding to a determined number of cups; then the filter is closed by folding the two flanges, as shown in solid lines in Figure 1 and as shown in Figure 2; then to keep the filter closed, the folded edges are embossed along the folding line, as shown at 3 in Figures 1 and 2. The filter thus pre-dosed and closed is then placed in a vacuum packaging 4, as shown in Figure 3.
Il est important de fermer le filtre une fois qu'il est rempli de la dose voulue parce que sinon il s'avère très délicat de réaliser la mise sous vide. De plus, contrairement à ce qu'il est dit dans l'addition 71.08130, la mise sous vide est impuissante à eviter que le café moulu se répande dans l'enveloppe. It is important to close the filter once it is filled with the desired dose because otherwise it is very difficult to carry out the evacuation. In addition, contrary to what is said in the addition 71.08130, the evacuation is powerless to prevent the ground coffee spilling in the envelope.
I1 faut donc fermer le filtre avant l'emballage sous vide pour éviter la diffusion de particules de café moulu. Selon l'invention, cette fermeture est obtenue par gaufrage parce que ctest un moyen très simple, mais on peut réaliser la fermeture par tout autre moyen tel que collage, thermosoudage ou couture. It is therefore necessary to close the filter before vacuum packaging to avoid the diffusion of ground coffee particles. According to the invention, this closure is obtained by embossing because it is a very simple means, but the closure can be achieved by any other means such as gluing, heat sealing or sewing.
La figure 4 représente une variante de réalisation selon laquelle on dispose deux filtres pré-doses dans un même emballage sous vide ; ledit emballage sous vide étant séparé en deux parties distinctes, ne communiquant pas entre elles, au moyen d'une bande de séparation 5. FIG. 4 represents an alternative embodiment according to which there are two pre-dose filters in the same vacuum packaging; said vacuum packaging being separated into two distinct parts, not communicating with each other, by means of a separation strip 5.
Pour faire du café, il suffit d'ouvrir l'emballage sous vide 4; puis on ouvre le filtre en saisissant les deux lèvres du rebord replié 2 en les écartant l'une de l'autre, ce après quoi, il n'y a plus qu'à mettre le filtre pré-dosé ainsi ouvert dans le support usuel sur une cafetière. To make coffee, just open the vacuum packaging 4; then the filter is opened by grasping the two lips of the folded rim 2, separating them from each other, after which, all that is left is to put the pre-metered filter thus opened in the usual support on a coffee maker.
A la figure 4, on a représenté un emballage sous vide comportant deux filtres, mais il est bien évident que l'on peut en disposer plusieurs. In Figure 4, there is shown a vacuum package with two filters, but it is obvious that we can have more.
Dans ce cas, il est préférable de disposer au moyen de bandes telles que la bande 5 autant de compartiments indépendants qu'il y a de filtres In this case, it is preferable to arrange by means of bands such as band 5 as many independent compartments as there are filters.
