USPTO Applicaton #: #20150314952
Inventors: Gunter Empl, Wolfgang Eppler, Andre Throm


The Patent Description & Claims data below is from USPTO Patent Application 20150314952, Single serve capsule for producing coffee beverages with and without crema.


The invention relates to a single serve capsule for producing a coffee beverage, wherein the single serve capsule has a capsule base body in which a textile fabric and a beverage substance are arranged, wherein the beverage substance is provided for storage in the single serve capsule and for extraction in the single serve capsule through the textile fabric by means of pressurized hot water, wherein the beverage substance is substantially pulverulent and comprises roasted, ground coffee, wherein the roasted, ground coffee has a color value in the range from 50 to 150.

Beverage preparations that are divided into portions in capsule or pad systems are generally known from the prior art. For example, generic single serve capsules for preparation of coffee and espresso are disclosed in documents EP 1792850 B1, EP 1344722 A1 and US 2003/0172813 A1. In addition, reference is made to the documents DE 102010034206, WO 2012/010317, WO 2012/038063 and DE 102011010534.

Single serve capsules for producing a beverage are preferably frustoconical or cylindrical and are produced, for example, from a deep-drawn plastic film or in a plastics injection molding process. They customarily have an open filling side having a flange, onto which a membrane (covering film) is sealed or glued, a closed or open capsule base, wherein, between the beverage substance and the capsule base, one or more assembly elements, such as, for example, a particle sieve, a liquid distributor, a fleece, a felt, a shut-off film and/or the like can be present.

To prepare a coffee beverage, the single serve capsule is introduced into a brewing chamber of a preparation apparatus. After, or during, the closing process of the brewing chamber, the single serve capsule is preferably opened on the closed base side thereof by means of an outlet spike arranged in the brewing chamber. Single serve capsules having partially open capsule bases already have one opening on the base side thereof. After the brewing chamber is sealed off, the filling side of the single serve capsule that is closed by a membrane or covering film is pierced by piercing means. Subsequently, preparation liquid, preferably hot water, is transported under pressure into the single serve capsule. The preparation liquid flows through the beverage substance and extracts and/or dissolves from the beverage substance the substances that are required for beverage production.

In the preparation of an espresso, for example a brewing water pressure of up to 20 bar acts on the coffee powder to extract the essential oils. This pressure, in addition, also acts on the filter medium which is situated between the coffee powder and the pierced capsule outlet of the capsule base. The sudden pressure drop on the bottom side of the filter medium leads to foam formation in the beverage, for example in the form of a crema of a coffee beverage.

Crema is obtained through the fineness of the particles, the filter system and a high pressure in the extraction volume. If the system is unpressurized, no crema is formed.

For certain beverages, for example the classic filter coffee without crema, which is consumed, in particular in the USA and Scandinavia, foam formation, however, is unwanted.

The amount of ground coffee required to obtain the desired beverage volume, which amount is present in a single serve capsule, increases virtually linearly with the beverage volume when the further charge material characteristics such as degree of roasting and degree of grinding correspond to the standard.

It is known that, particularly in the case of beverage amounts of greater than 150 ml, the additional extraction of the coffee grounds leads to washing-out of unwanted taste components which give the end product a bitter, acidic, stale taste. Obvious correction measures could be to increase the weighed portion or to grind the coffee beans finer. Increasing the weighed portion, however, leads to a poorer extraction, since the extraction medium can no longer wash around the particles uniformly. The reduction of the medium particle size increases the pressure in the extraction space. This leads to an additional extraction of unwanted components.

In the prior art, there are already system solutions which offer absolutely differing beverage productivities with an unchangeable fixed volume of the single serve packaging. However, these systems provide a disproportional volume store of the single serve packaging.

There is a need for single serve capsules for producing coffee beverages which have a uniform size and therefore can be part of a system solution. The single serve capsules should have a high productivity for coffee beverages of different volumes that are faultless in sensory quality.

There is especially a need for single serve capsules which, by changing individual, defined parameters, permit the production of different coffee beverages of good sensory quality.

The object of the present invention was to provide single serve capsules for producing coffee beverages which have advantages over single serve capsules of the prior art.

In particular, beverage preparations that are divided into portions having variable, market-specific beverage productivities should be provided in a predetermined, small-volume unchangeable packaging or storage volume. The variable, market-specific beverage productivities to be achieved should be in this case preferably between 20 ml and 170 ml. In addition, the beverage preparations obtained should be equivalent or enhanced in sensory quality to the beverages prepared in the previously customary preparation apparatuses.

In particular, coffee beverages of good sensory quality should be provided with different degrees of roast in the medium volume range (preferably 20 to 170 ml). In addition, these coffee beverages should be able to be produced optionally with crema or crema-free, wherein crema-free coffee beverages should correspond to the beverages which are prepared with apparatuses of unpressurized filtration.

These objects are achieved by the present invention, i.e. a single serve capsule for producing a coffee beverage,

wherein the single serve capsule has a capsule base body in which a textile fabric and a beverage substance are arranged,

wherein the beverage substance is provided for storage in the single serve capsule and for extraction in the single serve capsule through the textile fabric by means of pressurized hot water,

wherein the beverage substance is present in the single serve capsule in an amount in the range from 1 to 20 g;

wherein the beverage substance is substantially pulverulent, comprises roasted, ground coffee which in the dry state has a D[4,3] value in the range from 150 to 550 μm; and

wherein the roasted, ground coffee has a color value in the range from 50 to 150.

The D[4,3] value is the median volume D[4,3] which is a measured parameter known to those skilled in the art and can be used for describing the medium particle size.

It has surprisingly been found that by the special combination of single serve capsule configuration, filter medium, roasting curve of the roast coffee, median particle size of the ground roast coffee and amount of the coffee situated in the extraction volume, the beverage respectively to be achieved and also the desired beverage volume can be set.

According to the invention, the characteristics degree of roasting, degree of grinding and amount of coffee situated in the extraction volume (weighed portion) are varied and matched to one another in such a manner that even with very low weighed portions, high beverage volumes can be achieved, which correspond in sensory quality to the specifications. The yield of beverage volume per amount of coffee situated in the extraction volume can thus be improved.

In addition, it has surprisingly been found that not only the combination of a higher degree of grinding and a lower degree of roasting, and also the combination of a smaller degree of grinding and a higher degree of roasting yield beverages of good sensory quality. In addition, by targeted modification of the textile fabric, optionally a coffee beverage with or without crema can be obtained.

The volume of the single serve capsule according to the invention is preferably in the range from 20 to 35 ml.

In a preferred embodiment, the volume of the single serve capsule according to the invention is 25±10 ml, more preferably 25±8 ml, still more preferably 25±6 ml, most preferably 25±4 ml, and in particular 25±2 ml.

In another preferred embodiment, the volume of the single serve capsule according to the invention is 30±10 ml, more preferably 30±8 ml, still more preferably 30±6 ml, most preferably 30±4 ml, and in particular 30±2 ml.

The beverage substance present in the single serve capsule according to the invention is substantially pulverulent and comprises roasted ground coffee.

The coffee can be of a single variety, or consist of a mixture of two or more of any desired coffee varieties.

In a preferred embodiment, the beverage substance present in the single serve capsule comprises one or more coffee varieties selected from Arabica, Robusta, and Liberica.

In a particularly preferred embodiment, the beverage substance present in the single serve capsule comprises roasted, ground coffee, wherein the coffee is a mixture of the coffee varieties Arabica and Robusta.

In a further particularly preferred embodiment, the beverage substance present in the single serve capsule consists of roasted, ground coffee, wherein the coffee is a mixture of the coffee varieties Arabica and Robusta.

In a preferred embodiment, the beverage substance present in the single serve capsule comprises roasted, ground coffee, wherein the coffee is exclusively Arabica coffee.

In a further preferred embodiment, the beverage substance present in the single serve capsule comprises roasted, ground coffee, wherein the coffee is exclusively Robusta coffee.

The coffee can be decaffeinated.

The coffee can be flavored. Flavored coffee is preferably obtained in that the coffee beans, after the roasting, are treated with natural or synthetic flavorings or oils.

The bulk weight of the roasted, ground coffee, depending on variety and degree of grinding, is 250 g/l to 400 g/l. The bulk weight is determined by means of the Hag instrument. For this purpose, the ground coffee is placed into a container of known volume (250 ml) which, before filling, is tared on the balance. The coffee is filled into the container to overflowing and is skimmed off level on the upper container rim using a flat item. The full container is weighed against the tare weight and converted to g/l by means of a factor known to those skilled in the art.
