CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a National Stage of International Application No. PCT/EP2018/085715, filed on Dec. 19, 2018, which claims priority to European Patent Application No. 17210546.2, filed on Dec. 22, 2017, the entire contents of which are being incorporated herein by reference. FIELD OF THE INVENTION
[0002] The invention relates to the storing and dispensing of portioned beverage items for the preparation of beverages using such portioned beverage items in a beverage preparation device such as a coffee machine for in-home or professional use. BACKGROUND OF THE INVENTION
[0003] It is known that coffee is sold in airtight packages to protect it from contact with air that would cause quick oxidation and loss of aromas. The field of beverage sealed capsules has developed tremendously essentially because each coffee portion can be well protected against oxidation by a suitable gastight, functional package until coffee is extracted in a dedicated coffee machine.
[0004] For example, EP0512468 and EP0512470 provide respectively a beverage sealed capsule and a process for extracting a beverage from such capsule.
[0005] U.S. Pat. Nos. 8,178,139 8,210,097 provide respectively a spherical capsule comprising compacted aggregate of substance to be infused and a packaging envelope impermeable to air and water and a machine for automatically preparing and dispensing a beverage from such sealed capsule by puncturing the packaging envelope. In particular, the capsules are stacked in a reservoir above the infusion chamber and selected individually by a rear yoke forming part of the infusion chamber.
[0006] FR2879175 provides a coffee dose for automatic beverage and dispensing machines comprising an infusion chamber and a tamping position for a determined quantity of ground coffee in the infusion chamber. The coffee dose can be compacted from roast and ground coffee to a rolling external shape, a substantially spherical ball. The coffee dose further comprises an envelope of at least one layer or film of porous material imprisoning the coffee aggregate.
[0007] In general, the portioned package solutions which are designed to well preserve the coffee ingredient against oxidation provide many advantages such as freshness, coffee quality by perfect dosing and controlled extraction. However, they are expensive to produce, are generally package material consuming and may require a sophisticated packaging recycling chain.
[0008] Alternative dosing solutions have been developed for dosing and dispensing beverage ingredient portions which when individually taken are sensitive to oxidation but which are stored as a whole in a container in which the level of oxygen is reduced by a sealing protective packaging and/or by associating to the container dedicated vacuum or protective gas supply means when the container is connected to the dispenser device.
[0009] WO2014135677 proposes a device for controlled dispensing of capsules containing beverage ingredients wherein it comprises a discharge outlet for selectively dispensing the capsules and a barrier distribution area arranged within a capsule transport path and means for flushing inert gas in the capsule discharge chamber.
[0010] EP1876936 relates to an airtight coffee dispenser including a rigid container provided with a lid and an outlet nozzle closed by a shutter means. The dispenser includes means suitable to dispense from the container the product while reducing the storage volume.
[0011] EP1879487 relates to the dispensing of coffee powder from a dispenser including a storage container, shutter means and vacuum or inert gas supply to purge the dispensing chamber from oxygen.
[0012] The disadvantages of the existing solutions with a dedicated vacuum or inert gas production device is that it makes the system complex and costly to operate. Additionally, coffee ingredient dispensing solutions especially for coffee powder in bulk pose dosing accuracy problems and are not very clean as powder tends to spread over surfaces of the dispenser and beverage machine.
[0013] Therefore, a solution is sought after for providing a low cost, sustainable and simple dispenser device and system to precisely and reliably dispense beverage product ingredient, e.g. roast and ground coffee, for the preparation of beverage while maintaining product ingredient as fresh as possible and reducing packaging material consumption.
[0014] The present invention aims at overcoming the above-outlined problem of the prior art. Furthermore, the invention aims at providing a solution to further problems identified in the description. SUMMARY OF THE INVENTION
[0015] The invention relates to a portion dispenser for dispensing portioned beverage items (“beverage items”) from an exchangeable cartridge comprising: a frame with a receiving portion for receiving the exchangeable cartridge, a discharge opening next to the receiving portion and sized for allowing the beverage items to be individually discharged by gravity from the cartridge, a moving means assembly comprising moving means and a moving means housing in which the moving means are arranged for moving therein;
