Embodiment Construction

[0061] In the method of the invention, a beverage preparation device 1 with a capsule 2 inserted therein is provided. The device 1 comprises a capsule holder 3 , a water injection enclosure member 4 and a collector 5 .

[0062] The capsule holder 3 is formed by a support comprising protrusions such as truncated pyramids 6, grooves 7 between the protrusions, and holes provided through the holder 3 for draining the liquid extract through the capsule holder Mouth 8.

[0063] The water injection enclosing member 4 has a bell shape and includes an inner cavity 9 , an injection conduit 10 and a blade 16 capable of piercing a water injection hole in the inlet face of the capsule 2 . At the free end of the enclosing member 4 there is provided a pressing surface 17 comprising a plurality of radial grooves 15 as described in WO2009 / 115474 incorporated herein by reference. In the present invention, the grooves are here used to control a temporary water bypass between the capsule and th...

Abstract

Capsule for the preparation of a beverage in beverage preparation device comprising: a cup-shaped body comprising a cavity containing a beverage ingredient and a flange-like rim extending outwardly from the base of said body, a delivery wall connected to the flange-like rim, characterized in that the flange-like rim is formed of is a polymer material chosen in grade having a Vicat softening point (ISO 10350) between about 30 and 100 DEG C, preferably between 40 and 90 DEG C or apolymer chosen in grade comprising a glass transition temperature (Tg) between 30 and 80 DEG C,preferably between 40 and 60 DEG C.

Description

technical field [0001] The present invention relates to a capsule and a method for extracting a beverage such as coffee from a disposable capsule containing beverage ingredients, such as roast and ground coffee, inserted into a beverage production device. Background technique [0002] EP0468570 discloses a successful method of preparing beverages from capsules containing beverage ingredients. The principle consists in inserting a capsule containing coffee grounds and extracting the coffee liquid by tearing the delivery membrane of the capsule under the action of pressure against the capsule holder comprising a network system of small truncated pyramids. The truncated pyramids create controlled orifices in the membrane through which the coffee extract is filtered and flows out through the capsule holder before entering the discharge tube. [0003] Other published patents, such as EP1654966, EP1702543, EP1700548, EP1816936 and WO 2009 / 115474, relate to providing seals on caps...
