Definitions
- the invention relates to a beverage capsule for an espresso machine, in particular for making espresso under high pressure.
- the conventional espresso machine comprises a water chamber, a heating element adapted to heat the water to around 95-98 C, which is then pumped under high pressure of 15 to 19 bar to a filter holder or portafilter.
- Lower pressure systems also exist.
- the filter holder typically comprises a handle portion and a holder portion provided with two or three lugs that are adapted to engage in the installed position with the machine brewhead to where the water is pumped.
- the holder portion is adapted to receive a filter, which is usually a metal bowl with a number of perforations through its bottom. In use, the filter is filled with finely ground coffee and the water is forced through the coffee at the high pressure generated by the pump to produce the espresso coffee which is collected in a cup placed under the filter holder.
- the classic coffee machine suffers from two potential drawbacks.
- the first drawback is that ground coffee starts to lose its freshness and flavour after a few days and so for the optimum espresso, the user will also need to have a coffee grinder.
- the other drawback is that the used espresso coffee has to be removed from the filter, which can lead to mess as the grinds are fine.
- Coffee pods which can be used in many espresso machines.
- Coffee pods are generally individually wrapped to maintain freshness and consist of a small pod made of a perforated filter paper which contains the coffee. The pod is placed in the filter holder and then disposed of after use. Coffee pods are convenient but have to fit the filter holder and be placed correctly otherwise water can leak around the edge.
- a capsule machine typically has a two part mechanism.
- the first part receives the capsule and is provided with an extraction surface upon which the capsule rests.
- the second part is provided with a locking lever which is used to make the first and second parts integral.
- the second part cuts the upper surface of the capsule to allow water to enter the capsule and percolate down through the capsule, where it exits through the lower surface of the capsule at multiple locations determined by the geometry of the extraction surface.
- An example of such a machine is disclosed in EP0870457 or WO2005/004683 .
- Capsules in the known capsule coffee machines are, in use, inserted into a capsule cage of the machine which holds the capsule in position so that it may be cut by a cutting member.
- Capsule machines have proved to be commercially very successful as they are very convenient to use and produce a consistent product. However, each manufacturer's coffee machines and capsules are designed to work with the manufacturers own brand. The most popular brand of capsule is Nespresso®, which uses a sealed capsule made of aluminium. In use, the capsule is clamped into position in the machine with a capsule cage part holding the capsule so that it can be cut by typically three prongs to enable water under pressure to enter the coffee capsule.
- Nespresso® which uses a sealed capsule made of aluminium. In use, the capsule is clamped into position in the machine with a capsule cage part holding the capsule so that it can be cut by typically three prongs to enable water under pressure to enter the coffee capsule.
- Aluminium has the considerable advantage that it is oxygen and water impermeable, which means that the coffee in the capsules has a long shelf life. Aluminium however also suffers from several major drawbacks in that the aluminium is easily deformed during the filling and packing stage and it is difficult and expensive to produce a reliable seal on the capsule rim.
- the only known seal on the market that works is a silicone elastomer disclosed in EP1654966 despite significant research effort. In these capsules the edge of the aluminium rim is rolled over where the front foil seal is attached.
- the known solutions such as US2018/215120 and WO2013/029184 to these problems further require an extremely high capital investment beyond most companies.
- the present invention therefore seeks to provide an improved method of manufacture of a coffee capsule.
- apparatus for filling a capsule for use in a coffee machine which capsule has a generally frusto-conical form with an upper surface and a lower surface, an annular flange being provided at the lower surface, wherein an annular seal is provided on the annular flange comprising a cellulose material such as paper that deforms in use
- the apparatus comprises gasket application means, which applies a gasket to the capsule on the flange
- the apparatus further comprises gasket detection means for detecting the presence of a gasket on the capsule, capsule selection means being provided to enable capsules without a gasket to be rejected and capsules with a gasket detected to be packed.
- the apparatus further comprises capsule filling means, capsule sealing means for applying a foil to close a filled capsule, wherein manipulation means then invert the capsule, the inverted capsule then being moved through the machine to the gasket application means
- the aluminium capsule is pre-formed.
- the apparatus advantageously provides a good seal on the capsule which is more easily recycled than the known silicone seals.
- Figure 1 shows a capsule filling machine comprising stations 1 to 16. In stations 1-6, the empty capsule is fed in from a stack 1, the coffee is ground 2 and then the capsule filled by a doser 3 and then passed to the foil application station 5 to seal the capsule. #
- the capsule rim has a 12-degree angle applied during the lid foil application at head shaper 6. This angle tightens the lid foil after application, for cosmetic reasons. It also prevents a tangent leading edge, which helps reduce foil peel when capsule pressurises due to coffee degassing.
- the foil seal is cut from the reel at station 4 and the seal is then applied to close the capsule.
- the gasket is applied to an empty capsule in which case Stations 1 to 6 are not required.
- the capsule is rotated on the main conveyor belt from a lid foil facing up orientation to a lid foil facing down orientation to allow access to the gasket application area.
- the gasket material is fed from a reel of material into a die cutter 10, which cuts the gasket material from the material.
- a circle is punched from the reel of the material to form the inner circumference of the gasket.
- the circle of material is then removed using a vacuum tool.
- the outer diameter is then punched from the material to form the annular gasket.
- the annular gasket is then pushed downwards onto the capsule rim using compressed air jets 14 to speed up the movement of the gasket into the desired position.
- the gasket is applied to the capsule and at station 11 optical presence sensors are used to detect if the capsule has a gasket applied. If any capsule is detected not to have a gasket, that capsule is rejected as without the gasket, the capsule will leak in most capsule coffee machines.
- the fluorescence detector is provided with a sensor that provides a digital reading in response to the fluorescence detected. If the detected fluorescence is above a certain level, the detector will determine that there is a capsule with a seal there. If the reading is below that level the detector determines that there is no gasket and the capsule is rejected by not picking it off the conveyor belt and is directed into a waste bin, without the machine stopping.
- a laser could be used to measure the height from the rim and thereby deduce if a gasket is present or not.
- Capsules are lifted from the transport belt so that they can be independently aligned to the station above or below. This eliminates any position errors on the transport belt that might arise from wear within the machine / inertia / coffee residue etc.
- an adhesive may be required or alternatively pressure and/or heat alone may negate the need for an adhesive. From the perspective of recyclability, this is preferable.
- the gasket swages out and tightens around the internal diameter, creating a tight fit over the capsule. The outer diameter also increases, pushing the gasket under the rim of the capsule.
- Using no adhesive has advantages of being cheaper, easier to apply, store and to comply with food safety. Heat is applied to both sides of the seal.
- top sealer drops over the aligned gasket and capsule to bond them together.
- the system runs with a top sealing temperature of between 240-300°C, a bottom temperature of between 180-210°C with a dwell time of 350-450ms.
- Application of heat from both sides significantly reduces the dwell time in the machine so increasing its capacity and also reduces the likelihood of any heat damage to the seal caused by the direct application of heat from the top side due to the longer dwell time which would otherwise be required.
- the use of the lower temperature on the bottom sealing side does not cause any damage to the foil.
- the heat from the bottom may be in the range from no applied heat up to 170°C in particular in the case where the capsule interior is provided with a food safe coating such as PVC.
- heat to seal the gasket is applied from the top and the bottom when the lid foil is already applied to the capsule, so the lower sealer does not come into contact with the PVC liner and stick to it.
- the lid is not in place and the lower heater may stick to the PVC liner.
- the force applied to the sealing heads is controlled by a pressure dial on the machine. This pressure is excreted onto a 50.0mm diameter piston.
- the pressure typically used is in the range of 1 to 6, preferably 2-3 bar. #
- the pressure applied may be adjusted depending on the type of adhesive / gasket material used.
- the capsule is picked and placed onto an outlet conveyor belt connected to a cartoning machine so that the capsule can be packed.
