Embodiment Construction

[0080] The cartridge in the first mode of the present invention is Figure 1 to Figure 7 shown in . The cartridge 1 comprises a cup 2, preferably made of plastic. A suitable thermoplastic may be polypropylene or a multilayer of a polypropylene layer and a gas barrier layer such as EVOH. A possible multilayer could be PP-EVOH-PP. The cup is preferably obtained in one piece by injection molding. The cup comprises a body part 3 , a stepped part 4 , a collection area 5 and a tubular outlet part 6 .

[0081] At the upper end of the cartridge, an upper side edge 20 protrudes outwards, forming a sealing area for the lid 7 . The cover 7 may be a flexible membrane forming the water spray side of the cartridge. The injection of water is usually performed by piercing the membrane at one or several points in the membrane by means of a perforation system of the beverage preparation machine (not shown). Membranes are usually made from thin laminates of aluminum and / or polymers. For e...

Abstract

A cartridge (1) containing a food substance adapted to interact with water injected in the cartridge to produce a food liquid comprising: a cup (2) having a chamber for holding the food substance (10) and a lid (7), a puncturable delivery wall (8) that holds the substance in the chamber, a puncturing structure (11) to puncture at least one opening in the delivery wall as a response of water filling the chamber, a collecting area (5) for collecting the liquid passing through the delivery wall in a substantially axial direction; said collecting area being placed downstream the puncturable delivery wall (8), at least one liquid outlet (15) in the collecting area for allowing the liquid to leave the collecting area, wherein the cartridge comprises a support structure (12) comprising at least one support surface (14, 17, 18, 19) configured to support at least one portion of the delivery wall to maintain a flow gap between the puncture structure (11) and the at least one outlet (15).

Description

technical field [0001] The present invention relates to a single-use cartridge containing ingredients for interacting with a quantity of water sprayed into the cartridge to prepare a liquid. The cartridge is typically used for the preparation of liquid food products such as nutritional liquid preparations, eg infant formula, soup or beverages. The pod is usually inserted into a dispensing machine adapted to receive the pod for spraying water of suitable temperature and thus for quick, hygienic and convenient preparation of liquid food from said pod. Background technique [0002] A cartridge for dispensing liquid food in a dispensing machine such as a domestic take-out / serving system is known, for example, from WO 03 / 059778. The cartridge comprises a cup forming a chamber for holding food ingredients, a pierceable output wall such as a flexible membrane forming a physical / physical barrier to keep the ingredients in the chamber, for filling the chamber under pressure The act...
