Definitions
- the present invention relates to a pad for use in making a hot beverage such as coffee. including espresso, latte macchiato, caffe latte, caffe macchiato, cappuccino etc., and hot chocolate, including caffe choco etc., particularly to the preparation of a coffee using pads with ground coffee, and to an apparatus and method for manufacturing such pads.
- Preparing hot beverages such as coffee or hot chocolate using pads with raw material is known from practice.
- the pad In use, the pad is placed in a beverage machine and provided with a pressurized liquid that forces the liquid to flow through the pad to obtain the beverage.
- a problem of the known pads when used in existing beverage machines is that the flow through the pad, and especially the flow through the raw material contained therein, is not optimal and as a result the extraction from the raw material is not uniform.
- the present invention aims to provide a pad for preparing a hot beverage, such as coffee or hot chocolate that obviates or at least reduces the abovementioned problems.
- a pad for use in a beverage machine for preparing a warm beverage the pad being configured for holding a raw material through which a pressurized flow of liquid is forced for preparing the beverage, the pad comprising:
- first sheet having a surface area, wherein the surface area of the first sheet is provided with flow passages that are positioned at or near the outer perimeter of the first sheet;
- first sheet and the second sheet are connected to each other at or near the outer perimeter for forming an inner space for holding the raw material that is usable for preparing the beverage
- impermeable surface area and the flow passages cooperate for forcing the flow of pressurized liquid to flow substantially in a direction that is parallel to the surface areas through the raw material in the pad.
- connection to each other also includes similar terms as joining together, sealing and/or attaching, preferably in a durable manner. Most preferably, it includes sealing of the first and second sheet to form a fluid-tight connection that holds under pressure and/or heat.
- the connection and/or sealing may be formed using a variety of suitable manufacturing techniques may amongst others include gluing, hot melting, sewing and/or cross-linking.
- the pad according to the invention has the advantage that a flow is achieved in a direction that is substantially parallel to the surface areas. In most applications this means that in use a substantially horizontal flow of pressurized liquid is achieved through the pad. This enables fully utilizing the raw material contained in the inner space of the pad. In this text the term horizontal in relation to the flow direction through the pad is to be interpreted as substantially parallel to the surface areas.
- the improved utilization of the raw material is the result of the fact that at least one of the first and second sheets has a surface area that is at least partially impermeable to pressurized liquid, which forces the flow of pressurized liquid to flow through the pad in a substantially horizontal direction.
- the pad is placeable in a beverage machine with the first sheet facing towards a pressurized liquid supply of the machine or, alternatively, with the second sheet facing towards the pressurized liquid supply.
- the pressurized liquid is redirected, preferably by the impermeable surface area of the first sheet, towards the flow passages near the outer edge. This is achieved regardless of the exact positioning of the liquid inlet in the beverage machine.
- the flow of pressurized liquid is directed inwardly towards the preferred centralised outlet/flow passage(s) in the second sheet and the preferred central outlet of the beverage machine.
- the second sheet is optionally also substantially impermeable to direct or guide the flow.
- directing or guiding the flow is the result of the bottom part of the pad holder. In any case, as a result, in use a substantially horizontal flow through the pad is achieved.
- the flow of pressurized liquid after having centrally entered the pad through the flow passage(s) in the second sheet, encounters the impermeable surface of the first sheet and/or the bottom of the pad holder and is forced to flow in an outward direction towards the flow passages positioned near the outer edge.
- the product After passing the decentrally positioned flow passages, the product may flow underneath the pad towards a central outlet of the beverage machine. As a result, a substantially horizontal flow through the pad is achieved.
- the raw material is more efficiently used than in existing pads and the amount of raw material that is needed to achieve a similar or higher quality beverage is reduced compared to existing pads.
- Another advantage of the pad according to the invention is that the formation of preferential flow paths in the raw material is substantially prevented.
- the flow of pressurized liquid from the liquid inlet of a beverage machine often slightly displaces raw material in the pad upon entering the pad, therewith forming a flow path having a lower flow resistance. Because liquid flows along the path of least resistance, the pressurized liquid is inclined to form and subsequently follow the path of the least resistance.
- the impermeable surface of the first and/or second sheet preferably provides an increased stiffness to the pad. which reduces crumpling and/or creasing of the pad.
- Existing pads are relatively flexible, which, when introducing the pad into the beverage machine, increases the risk of crumpling and/or creasing of the pad.
- preferential flow paths may already be formed and/or the sealing of the pad in the beverage machine is reduced, allowing a flow of pressurized liquid to bypass the pad entirely.
- the pad according to the invention has in increased stiffness, which reduces the amount of crumpling and/or creasing, making it easier to correctly introduce the pad in the beverage machine. Therewith the risk of leakage along the seal is reduced.
- the additional impermeable surface or surfaces contributes to maintaining the raw material in the pad fresh. This improves the overall quality assessment by a consumer.
- the pad according to the invention can advantageously be used in existing beverage machines without having to adapt the beverage machines.
- the size of the impermeable surface and the exact positioning of the flow passages are chosen such that a substantially horizontal flow is achieved through the raw material in the pad. According to the invention, this may be achieved in various ways.
- the flow passages in the first sheet may comprise a ring at or near an outer edge of the pad, which forms a single circular flow passage for the pressurized flow of liquid to flow into the pad.
- multiple flow passages are positioned near or at the outer edge of the first sheet, which for example may be used when the preferred impermeable surface is substantially equal to the surface of the first sheet.
- only a limited number of flow passages may be applied to the surface area of the first sheet.
- the surface of the second sheet preferably is provided with a single flow passage for allowing a flow of liquid to exit the pad or may be provided with a number of flow passages that can for example also be configured to be positioned in a ring in the second sheet. Preferably, such a ring of flow passages would be near or at the centre of the pad.
- the pad according to the invention may be inserted in a beverage apparatus with the first sheet facing upwards, i.e. in the direction of a liquid supply/inlet by the apparatus, or with the first sheet facing downwards towards a liquid outlet of the apparatus.
- a pad is provided to an end-user along with an instruction on how to use the pad and/or the orientation to be used for each type of beverage machine. Most preferably, such instructions are provided along with a brand on the pad itself.
- the first sheet is impermeable to the flow of pressurized liquid.
- the second sheet may also be provided with an impermeable surface and at least one flow passage.
- the first sheet in use is facing upwards towards the liquid supply/inlet of the machine. Tests have shown that such embodiment provides an effective use of the raw material.
- An advantage of providing an impermeable surface on both the first and second sheets is that the pad can be used in existing beverage apparatus having for example a decentral liquid inlet and a decentral liquid outlet, for example.
- the pad may be substantially circular, and a diameter of the pad may be in the range of 10 to 100 mm, preferably in the range of 35 to 75 mm, and may more preferably have a diameter of around 60 mm.
- the size of the pad is preferably chosen such that it is usable in existing beverage machines. In most beverage machines circular pads having a diameter of around 60 mm are used. The form and dimensions of the pad are preferably manufactured such that they can be used in existing machines.
- the pad and each of the impermeable surface areas may be substantially circular and the diameter of each of the impermeable surface areas may be in the range of 10 - 100 % of the diameter of the pad, preferably in the range of 70 - 100% of the diameter of the pad, and more preferably in the range of 90 - 95% of the diameter of the pad.
- the area of the impermeable surfaces in relation to the total surface of the surface area of the sheet may advantageously be adapted specific consumer or retailer requirements. This may for example relate to the type of beverage machine for which it is used and/or the type of raw material contained in the pad.
- the impermeable area of the second sheet may be smaller, since the flow of pressurized liquid is forced to flow towards in a substantially horizontal direction due to the fact the outlet is centrally placed.
- the properties of the impermeable surface may also depend on the pressure that is used in the beverage machine.
- the first and second sheets may be manufactured from a material that is permeable to liquid, such as paper, preferably filter paper, wherein the impermeable surface area may be formed on one or both of the first and second sheets during manufacturing.
- the pad according to the invention may be manufactured by providing a pad having sheets made of permeable material, such as present in existing pads, which are subsequently provided with an impermeable layer that is formed in or on the surface of the first and/or second sheet.
- the impermeable layer may be applied on the surface of the sheet or may be applied into the sheet, forming an integral layer therewith.
- the forming of the impermeable surface area may be performed using one of a group of: coating, spray coating, gluing, printing, rolling, stamping, hot melting or stitching.
- the impermeable surface area of the sheets can be applied to the sheet using one of a variety of different techniques.
- the specific technique chosen for applying the impermeable surface area is preferably adapted to the type of material that is used for the impermeable surface area.
- the first and/or the second sheet may be manufactured from a material that is impermeable to liquid.
- the pad may have one or both sheets manufactured from an impermeable material, which obviates the step of forming the impermeable surface area to the pad. This reduces the cost and complexity of the manufacturing process, therewith also reducing the cost of the manufactured pads.
- the impermeable surface area may be formed or manufactured from a material that may be one of a biodegradable plastic material, such polylactic acid (PLA), or a compostable plastic material or a thermo-compressed paper.
- a biodegradable plastic material such as polylactic acid (PLA)
- PLA polylactic acid
- a compostable plastic material such as thermo-compressed paper.
- the materials are also food-grade materials that are accepted and/or certified for use in food-related products.
- one or both of the impermeable surfaces may be provided with a relief, an embossing and/or channels for guiding the flow of pressurized liquid.
- the impermeable surface layers applied to the surfaces of the first and second sheets may be provided with an embossing, relief and/or channels during the manufacturing.
- This may for example be executed by providing a variation in the thickness of the applied layer over the surface area.
- the relief or embossing for example allows a manufacturer to apply a logo, brand or even instructions in the impermeable layer. Applying a logo, brand or instructions, or any other figures and/or text onto the impermeable layer may be performed using a suitable technique, such as stamping or integral shaping during application of the impermeable layer.
- An advantage of such relief or embossing is that the pad may be provided with specific instructions on the use and/or how the pad is to be placed in specific beverage machines.
- the impermeable layer comprises an amount of an aromatic and/or flavouring substance. This may improve the overall appreciation of a user.
- providing preformed flow channels in the impermeable layer or layers in the pad may provide that the flow of pressurized liquid is guided more fully along the outer side of the pad from the liquid inlet to the flow passages in the first and/or second sheet.
- Flow channels are preferably applied on an outer side of the pad and are preferably also applied on the side of the pad that faces the liquid inlet, although it may additionally or alternatively also be provided on the side facing the liquid outlet.
- the invention also relates to a system for manufacturing coffee pads according to the invention, the system comprising:
- a pad manufacturing apparatus for manufacturing pads preferably coffee pads, at least comprising:

- a pad manufacturing apparatus for manufacturing (existing) pads in practice often comprises a blanking device for removing and/or punching the manufactured pads out of the feeds of base material, which often comprise semi-continuous sheets of material that are provided to a feed on a roll.
- an additional production step is preferably provided to the apparatus, the production step preferably being positioned between the last manufacturing step, for example the blanking device that punches the pads from a feed, and the packing device for packing the completed pads.
- the conveyor preferably is an endless conveyor on which the pads are placeable and that is positioned under an angle with the production line of the pad manufacturing apparatus.
- the conveyor when placed near a blanking device of the pad manufacturing apparatus, is further preferably placed slightly underneath the blacking device to capture the punched out pads on the conveyor for subsequent transportation to the layer application device.
- the layer application device may be a rotatable spray gun that is configured for spraying a coating on the first sheet of the punched out pads.
- the advantage of a rotatable spray gun is that the layer application device and the pad are not brought in contact with each other. Furthermore, a rotatable spray gun allows a relatively high processing speed.
- Other layer application devices can be used as well, such as a coating device that applies a coating to the first sheet by means of gluing or hot melting. Both the use of a (rotatable) spray gun or a coating device have the advantage that they can be used to apply the impermeable layer to the sheet when the pad is already filled with raw material without having any adverse effect on the raw material in the pad.

- This embodiment has the advantage that it can be applied in conjunction with an existing method for manufacturing pads without having to adapt the process as such. Instead, the method provides an additional step in which the impermeable layer is applied to one or both of the first and second layer.
- Another advantage of this embodiment according to the method is that the size of the impermeable layer may be adapted to the specific requirements of a client, in that the size may be chosen to be substantially the entire surface or only a part of the surface of the respective sheet. Furthermore, the size of the impermeable layer that is applied on the respective sheets may differ for each of the respective sheets. Therewith, the method allows a large measure of flexibility and freedom with regard to the pads that are manufactured.
- providing at least one of the first and second outer surfaces with a layer of material that is impermeable to pressurized liquid is executed by manufacturing at least one of the first and second sheet of the pad from a material that is impermeable to pressurized liquid, the embodiment further comprising applying a number of flow passages in the impermeable sheets to allow the passage of pressurized liquid.

- a number of decentral flow passages 12 in first sheet 4 function as inlet and central flow outlet 22 of beverage machine 18, and particularly a pad holder thereof, functions as outlet.
- pad 2 may be used in various ways to provide a substantially horizontal flow through pad 2.
- pad 2 in beverage machine 18, for example beverage machine 18 having central inlet 20 and central outlet 22, pressurized liquid flows on impermeable surface 10 of sheet 4 and is directed towards sealing edge 8.
- the pressurized liquid enters pad 2 through flow passages 12 that are present near outer edge 4a of sheet 4 (see also figure 3a, figure 5a) and is subsequently forced to flow substantially horizontally between impermeable surface 10 of sheet 4 and lower surface 18a of beverage machine 18 towards centrally placed beverage machine outlet 22.
- the combination of pad 2 with beverage machine 18 forces the pressurized liquid to flow substantially horizontally through pad 2, thereby obtaining a more efficient extraction and/or mixing process.
- pad 2 can be used in existing beverage machines without having to adapt the existing beverage machines to pad 2.
- Manufacturing process 102 (figures 6a, 6b) comprises a number of conveyor belts 104 that transport pads 106 from and to a conventional pad manufacturing line 116. Pads are transferred to conveyor belt 108.
- Layering device 110 provides the impermeable layer to pad 106.
- one device 110 is provided.
- a second device 1 10 can be provided to provide the other surface of pad 106 with an impermeable layer.
- treatment device 1 12 is provided. This may involve a heating device to perform a heat treatment to the impermeable layer.
- drive system 1 14 connects the individual drives of conveyors 104, 108 and device 110, such that these drives are synchronized with the other components of the manufacturing line.
- the impermeable layers are already provided on the pad material directly. This obviates the need for including separate device(s) 1 10. It will be understood that other methods and devices can be envisaged to provide the impermeable layer(s).
