Embodiment Construction

[0123] like Figure 11 As shown, the cartridge 1 of the present invention generally comprises an outer part 2 , an inner part 3 and a laminate 5 . The outer part 2, the inner part 3 and the laminate 5 are assembled together to form a cartridge 1 having an interior 120 for containing one or more beverage ingredients, an inlet 121, an outlet 122, and connecting the inlet 121 to the outlet 122 And through the beverage flow path of the interior 120 . The inlet 121 and outlet 122 are initially sealed by the laminate 5 and are opened by piercing or cutting the laminate 5 in use. The beverage flow path is defined by the spatial interrelationship between the outer part 2, the inner part 3 and the laminate 5, as described below. Other components may optionally be included in the cartridge 1, such as a filter 4, as described further below.

[0124] exist Figures 1 to 11 Shown is a first version of the cartridge 1 that will introduce the use described for the background art. The fi...

Abstract

A cartridge (1) containing one or more beverage ingredients (200) and being formed from substantially air- and water-impermeable materials, the cartridge comprising an inlet (121) for the introduction of an aqueous medium into the cartridge and an outlet (122) for discharge of a beverage produced from the one or more beverage ingredients, wherein the cartridge comprises an outer member (2) and an inner member (3) conjoined on assembly with the outer member, characterised by the inner member comprising a discharge spout (43) defining the outlet of the cartridge.

Description

technical field [0001] The present invention relates to cartridges for preparing beverages, and more particularly to hermetically sealed cartridges formed of a substantially air and water impermeable material and containing one or more ingredients for preparing beverages. Background technique [0002] It has previously been proposed to seal beverage preparation ingredients in individual airtight packages. For example, cartridges or capsules containing instant ground coffee are known for use in certain coffee preparation machines, commonly referred to as "espresso" machines. In the production of coffee with these preparation machines, a coffee cartridge is placed in the brew chamber and hot water is passed through the cartridge at high pressure to extract the aromatic coffee components from the ground coffee to produce coffee drinks. Typically, such machines operate over 6×10 5 Work under the pressure of Pa. Preparation machines of the above-mentioned type are by far rela...
