Embodiment Construction

[0045] figure 1 , 1A , 2 and 3 show the capsule 1A of the first embodiment of the present invention. The capsule 1A comprises an outlet wall 3 and a self-supporting cup-shaped body 2 of circular section with a closed upper wall portion for injecting water into the capsule, a frusto-conical side wall 4 extending outwards. and terminates at the edge 5 of the rolled-up end 6 . As mentioned above, the body can be made of aluminum, plastic and / or paper, and can be relatively rigid so that it does not collapse when it is pierced by the blade of the coffee preparation machine; the blade provides passage through the capsule for filling opening. The cup-shaped body defines a chamber 8 containing beverage ingredients, preferably roast and ground coffee. The amount of roast and ground coffee used can vary depending on the type of coffee (ristretto, espresso or lungo). Typically, the amount of coffee contained in the chamber is between 4.5 grams and 7 grams. Coffee powder is general...

Abstract

A capsule for preparation of a beverage in a beverage production machine. The capsule includes a body and a delivery wall forming a chamber containing ground coffee. The delivery wall has at least one outlet, an inner layer and an outer layer forming respectively first and second layers at least partially connected together by at least one seal portion which delaminates or breaks under the pressure of coffee liquid against the seal portion. Preferably, the seal portion extends in a direction (P) which differs from the direction (A) of the outlet.

Description

technical field [0001] The present invention relates to capsules for preparing a beverage, such as coffee, in a beverage preparation machine. Background technique [0002] Single-use beverage capsules are popular because they provide quick, convenient and clean delivery of fresh-tasting beverages. Accordingly, certain beverage capsule systems propose extracting coffee liquid from roast and ground coffee ingredients contained in a capsule which opens under pressure when a sufficient amount of water is filled into the capsule. More specifically, before the outlet face of the capsule opens, the pressure of the liquid in the capsule increases, thus creating a good extraction quality. [0003] For sufficient interaction between ingredients such as ground coffee and hot water it is desirable to delay the release of the beverage through the delivery side. Many different solutions already exist. In particular, as described in EP0512470B1, Nespresso The capsule system is based o...
