A cartridge containing one or more beverage ingredients and being formed from substantially air- and water-impermeable materials. The cartridge comprises an inlet for the introduction of an aqueous medium into the cartridge, and an outlet for a beverage produced from the one or more beverage ingredients. The cartridge comprises means for producing a jet of the beverage having an aperture in a beverage flow path linking the inlet to the outlet, and one or more microscopic projections at or in the vicinity of the aperture for contacting the beverage flow path.

Cartridge for the preparation of beverages

A cartridge containing one or more beverage ingredients and being formed from substantially air- and water-impermeable materials, the cartridge comprising a compartment containing the one or more beverage ingredients, the compartment comprising a plurality of inlet apertures for the introduction of an aqueous medium into the compartment and a plurality of outlet apertures for a beverage produced from the one or more beverage ingredients, wherein at least a proportion of the inlet apertures are out of alignment with the outlet apertures such that at least a proportion of the aqueous medium entering the compartment through the inlet apertures is forced to circulate within the compartment before exiting the compartment through the outlet apertures, characterised in that the inlet apertures are arranged around the periphery of the compartment.

A beverage is prepared employing a package containing at least one beverage ingredient, e.g. roast and ground coffee. The package (10;200) is located at a brewing station, the package is pierced by a tool (49;248) to form an outlet opening (38;202) in the package, an aqueous medium, e.g. hot water, is introduced into the package, the aqueous medium is allowed to commingle with the beverage ingredient, and the beverage so formed is collected through the outlet formed in the package. The piercing tool is employed both to form the outlet opening, and to fold the material (117;204) surrounding the opening out of the path of the beverage which subsequently emerges through the outlet opening.

Method for preparing beverages

A beverage is prepared employing a package (10) having a compartment (111) containing at least one beverage ingredient, e.g. roast and ground coffee. The package is located at a brewing station, an aqueous medium, e.g. hot water, is introduced into the package, the aqueous medium is allowed to commingle with the beverage ingredient, and the beverage so formed is collected through an outlet (38) formed in the package. The compartment of the package is sealed by a covering material (119) which determines one dimension of at least one opening (115) acting to filter the beverage passing out of the compartment to the outlet of the package. The package is also clamped at the brewing station prior to the introduction of the aqueous medium in a manner which maintains said one dimension during the subsequent formation and collection of the beverage.

Method for preparing beverages and beverage preparing machines

The invention is concerned with a machine for preparing a beverage employing a package (10;200) containing at least one beverage ingredient, e.g. roast and ground coffee. The machine has a point of entry (16;209) for the package into the machine, a brewing station within the machine at which the package is supplied with an aqueous medium to produce the required beverage, and drive means (24;217, 221, 222) which engage the package at the point of entry and convey the package to the brewing station. The drive means includes a coupling between a drive part (243;226) and a part (30;252) associated with the package, the coupling enabling the drive to the package to be engaged and disengaged and allowing the part associated with the package to move independently of the drive part.

Beverage preparing machines

A sealed beverage package containing one or more beverage ingredients and being formed from substantially air- and water-impermeable materials, the said package comprising a body portion having a compartment containing the beverage ingredients and a beverage outlet channel formed therein, the beverage outlet channel and the compartment of the body portion containing the beverage ingredients communicating in such a manner that, in use, the said compartment and the outlet channel co-operate to act as a filter during the preparation of a beverage from the package.
