Beverage system

An adapting device for use in the system for preparing food or beverage products, comprising:

• a machine comprising:
• fluid circulation member to circulate a fluid to a capsule,
• a capsule holder having a housing for holding said capsule, and
• an injection plate for injecting said fluid into the capsule compartment,
• said holder and plate being movable relative to one another in order to enclose said capsule,
• a first type of capsule, said capsule comprising a capsule body having side walls forming an ingredient compartment, an upper membrane closing the upper part of the body and attached on the upper surface of a rim extending outwardly from the side walls, and a bottom membrane closing the lower part of the capsule body, said bottom membrane being openable by an opener under the effect of the rise in pressure within the capsule compartment, and
• a second type of capsule comprises said capsule comprising a capsule body having side walls forming an ingredient compartment and a lower rigid wall attached to the side walls such that the bottom membrane of said second type of capsule is located within the capsule compartment, above the upper surface of said rigid wall, the second type of capsule further comprising a product-dispensing channel connecting the upper and lower sides of said lower rigid wall, and a product-dispensing conduit extending downwardly from said product dispensing channel, the upper surface of said lower rigid wall comprising an opener adapted to open said bottom membrane, and
• a device for adapting the first and second types of capsule in the capsule holder of the food or beverage preparation machine, wherein said device comprises:
• a device plate with an attachment member to the capsule holder,
• the opener located at the upper surface of said device plate and protruding upwardly from the upper surface plane of said device plate, said opener being adapted to open the bottom membrane of the first type of capsule in order to allow a first type of food or beverage product to be dispensed, and
• a central through-hole extending through the whole thickness of said plate, for receiving the product-dispensing conduit of said second type of capsule wherein said device comprises:
• a device plate with attachment means to the capsule holder,
• the opener located at the upper surface of said device plate, and protruding upwardly from the upper surface plane of said device plate, said opening means being adapted to open the bottom membrane of the first type of capsule in order to allow a first type of food or beverage product to be dispensed, and
• wherein the central through-hole of said device plate is surrounded, at the upper surface of the device plate, by a circular wall protruding upwardly from said upper surface, at a height which is at least equal, or superior, to the height of opener.
