Definitions

  • the invention relates to cartridges for preparing beverages and methods of manufacturing such cartridges.
  • the substance is often held within a filter or pod which is secured within the cartridge.
  • the pod is water-permeable, and may be made of a material which can be torn by the piercing elements that create the entrance and exit points. There is also a risk of damage to the pod due to high pressures within the cartridge.
  • a cartridge for the preparation of beverages comprising a container for defining an interior space, a separating element for defining two portions of the interior space, one or more supporting elements for positioning the separating element in a desired location, and a pod for containing the substance from which the beverage is to be extracted.
  • the separating element is constructed to allow fluid communication between the first and second portions of the interior space.
  • the pod is disposed on the separating element.
  • the separating element is formed separately from the container and disposed within the container as an unaffixed piece. Similarly, the pod is supported only by the separating element. It is believed that this may reduce manufacturing costs, since the pod and separating element will remain in place without any fasteners or adhesives. Thus, steps of affixing the pod and the separating element to the container are not required.
  • Figure 1 is a front view of the cartridge and its components.
  • Figure 2 is a front view of the container.
  • Figure 3 is a front view of a different embodiment of the cartridge.
  • Figure 4 is a front view of one embodiment of the separating element.
  • Figure 5 is a top view of one embodiment of the separating element.
  • Figure 6 is a top view of another embodiment of the separating element.
  • Figure 8 is a front/top perspective view of another embodiment of the separating element.
  • Figure 9 is an exploded view of another embodiment of the cartridge and its components.
  • Figure 10 is a front/top perspective view of another embodiment of the separating element.
  • Figure 11 is a front view of another embodiment of the container.
  • Figure 12 is an exploded view of another embodiment of the cartridge and its components.
  • Figure 13 is a front view of another embodiment of a cartridge.
  • the word "form” and any of its derivatives, including but not limited to the words “formed” and “forming”, are defined to mean any method or any step of a method of creating an article.
  • “form” includes, but is not limited to, injection moulding, deep drawing, punching, compression forming, vacuum forming, heat sealing, and ultrasonic welding.
  • the method may furthermore comprise multiple steps, such as in the case that a first component of an article is manufactured, and a second manufactured component is then affixed to the first component.
  • the cartridge comprises a container 110, a separating element 120, one or more supporting elements 130, and a pod 140 containing a powder, grounds, or other substance from which the beverage may be extracted, such as ground coffee beans or tea leaves, for example.
  • the pod 140 can include a filter, sachet, or other bag that is permeable to fluids while retaining the substance (from which the beverage may be extracted) within it.
  • a beverage additive may be disposed loosely, or in a second pod, between the separating element 120 and the bottom surface 112 within the second portion 116.
  • the beverage additive may, for example, be a powdered cream or milk, or cream or milk replacement, non-dairy cream, foam cream, sugar, chocolate, essence, mint powder, or other foods or substances.
  • the beverage additive may be added to enhance the flavour, nutrients, appearance and/or aroma of the resulting beverage.
  • the cartridge 100 is placed in a machine which injects a liquid into the first portion 115 of the interior space 114 by means of an inlet.
  • the inlet can be formed by a piercing element of the machine which can also inject the liquid.
  • the liquid extracts the desired aromas and flavours from the substance.
  • the resulting flavoured beverage is communicated by the separating element 120 and into the second portion 116 of the interior space 114 by the pressure, gravity and/or other motive force.
  • a beverage additive has been disposed between the separating element 120 and the bottom surface 112, the flavoured beverage mixes with the beverage additive.
  • the flavoured beverage then exits the cartridge 100 by an outlet, which can also be formed by a piercing element.
  • the flavoured beverage may then pass into a beverage receptacle for consumption.
  • the lid 113 is piercable to form an inlet, which may be created by a first piercing tool 200, to accommodate the inflow of a liquid, such as water.
  • a liquid such as water.
  • one or more side walls 111 along the first portion 115 may be pierced using a first side piercing tool 202 to form the inlet.
  • the bottom surface 112 is piercable to form an outlet, which may be created by a second piercing tool 300, to accommodate the outflow of the beverage.
  • a second piercing tool 300 to accommodate the outflow of the beverage.
  • one or more side walls 111 along the second portion 116 may be pierced using a second side piercing tool 302 to form the outlet.
  • FIGS 4 , 5 , and 6 show embodiments of the separating element 120.
  • the separating element 120 comprises a first surface 121 sufficient to support the pod in the first portion 115 of the interior space 114.
  • the separating element 120 extends toward the side walls 111, though not necessarily a snug fit along the side walls 111, as will be explained below.
  • the first surface 121 of the separating element 120 is generally shaped as a substantially planar surface to support the pod, while a second surface 122 on the opposing face of the separating element facing the second portion 115 of the interior space 114 need not have any specific shape as it does not need to support the pod.
  • the separating element 120 permits fluid communication from the first portion 115 to the second portion 116 of the interior space 114.
  • drainage passages 123 extend from the first surface 121 to the second surface 122, permitting fluid communication from the first portion 115 to the second portion 116 of the interior space 114.
  • fluid communication is achieved by forming the separating element 120 from a water permeable material.
  • fluid communication is achieved by forming the separating element 120 such that it is not a snug fit along all of the side walls 111 (such that its widest dimension is smaller than the adjacent dimension of the side walls of the container), thereby permitting fluid to pass between an edge of the separating element 120 and the one or more side walls 111.
  • the separating element elevates the pod so as to prevent damage to the pod due to contact with the piercing tool 300. Additionally, the first surface 121 of the separating element 120 supports the pod 140 which may assist to prevent tearing under the pressure of the injected liquid.
  • the separating element 120 comprises a plurality of concentric rings, joined by one or more spokes which extend radially from the centre of the rings toward the outermost ring, with the drainage passages 123 being the gaps between said rings.
  • the separating element comprises two concentric rings joined by one or more spokes, the rings being separated by a distance greater than the width of a widest ring. It should be understood that individual spokes need not extend from the centre of the rings toward the outermost rings, but could instead by replaced by a set of discontinuous spokes joining the rings together in any way. It should also be understood that either the spokes or rings could be omitted to provide a non-unitary separating element, though such an embodiment may be more complex and costly.
  • the supporting elements 130 may be independent of the separating element 120 and/or cartridge 100, or they may be integral components of another element of the cartridge 100.
  • the supporting elements 130 may be formed with the separating element 120 or with the one or more side walls 111 of the container 110.
  • a second separating element 220 is connected to the ends of the supporting elements 130 opposite the separating element 120.
  • the second separating element 220 permits fluid communication from the second portion 116 to a beverage receptacle via an outlet formed by a piercing element.
  • the second separating element 220 has the same shape, structure, and drainage passage pattern as the separating element 120, which in this example, comprises a plurality of concentric rings and radial spokes, and drainage passages 123. It will be appreciated that the second separating element 220 may comprise of a different shape, structure, and/or drainage passage pattern than the separating element 120.
  • the second separating element 220 can facilitate the placement of a combined structure of the separating element 120, supporting elements 130 and second separating element 220 within the container 110, without having to specifically align the free ends of the supporting elements 130 to abut the bottom surface 112 of the container 110 such that the supporting element 120 is spaced apart from the bottom surface 112 of the container 110 (as shown in Figure 7 ).
  • either separating element 120 or 220 can be aligned to abut the bottom surface 112 of the container 110, resulting in the other separating element to be spaced apart from the bottom surface 112 to support the pod 140.
  • the second piercing tool 300 can be aligned with the drainage passages 123 of the separating element abutting the bottom surface 112, so as to not pierce through the separating element.
  • the piercing tool 300 can pierce through the separating element abutting the bottom surface 112 when forming an outlet to the container 110.
  • the outlet can be formed along the side walls 111 using the second side piercing tool 302.
  • the supporting elements 130 may be independent of the separating elements 120 and 220, or they may be integral components of the separating element 120 and/or the second separating element 220.
  • the supporting elements 130 may be a set of a least three members formed integrally with the separating element 120, extending from the second surface 122 of the separating element 120 at one end to a surface of the second separating element 220 at its other end.
  • FIG. 10 illustrates an example spacer 300 comprising a plurality of walls 310 interconnected with one or more other walls 310.
  • the spacer 300 comprises six walls 310 connected at its centre to form a six-spoke star-shape.
  • the supporting elements 330 comprise the walls 310
  • the separating element 320 comprises the first surface 321 formed by the top traverse edges of the walls 310
  • the second separating element 420 comprises the second surface 422 formed by the bottom traverse edges of the walls 310.
  • the separating element 320 or second separating element 420 can be aligned to abut the bottom surface 112 of the container 110, with the other separating element supporting a pod 140.
  • the pod 140 when supported by the separating element 320 or second separating element 420, is spaced apart from the bottom surface 112 by the height of the walls 310.
  • the interstitial spaces or gaps defined by adjacent walls 310 serve as drainage passages 323 for enabling fluid communication between the first surface 321 and the second surface 422.
  • the number of walls 310 can differ from that shown in Figure 10 (e.g.
  • the walls 310 can be connected in other configurations to form different cross-sectional shapes of the spacer 300.
  • One or more walls 310 may also have different thicknesses from other walls 310 and/or be non-uniform along a single wall 310. It will also be appreciated that the walls 310 can be integrally formed, or individual formed and then attached to other walls 310.
  • the supporting element 830 is formed integrally with the container 810.
  • the supporting element 830 may comprise one or more steps, ledges or protrusions protruding inwardly within the interior space 814, in the one or more side walls 811 of the container 810, producing a container within which the smallest diameter of the first portion 815 is greater than the largest diameter of the second portion 816.
  • the separating element 820 which may be a disc, has a diameter equal to or slightly smaller than the smallest diameter of the first portion 815 of the container 810 and larger than the largest diameter of the second portion 816 of the container 810, thereby enabling the separating element 820 to rest on the step between the first and second portions.
  • the container 110 may be formed, typically, by deep drawing or injection moulding, of a heat resistant material which is impervious to water.
  • the container may be formed in two steps.
  • the side walls 111 and the bottom surface 112 may be formed as a continuous piece, and the lid 113 may later be attached after the separating element 120 and pod have been inserted into the portion of the container comprising the side walls 111 and the bottom surface 112.
  • the separating element 120 may be formed separately from the container, and of a heat resistant material which is impervious to water.
  • the material is also sufficiently rigid to maintain a substantially parallel relationship among the major surfaces 121 and 122 of the separating element 120, the lid 113, and the bottom surface 112 of the container 110, while supporting the weight of both the liquid contained within the first portion 115 of the interior space 114 and the saturated pod 140, as well as the pressure from the injected liquid. That is, the separating element 120 should not deform under the pressure commonly experienced within the container 110, but should maintain a consistent relationship between the sides of the first and second portions 115 and 116 of the container 110, thereby preventing contact with the second piercing tool 300.
  • the separating element 120 may be positioned on the supporting elements 130 within the container 110.
  • the lid 113 may be punched from a piercable material and heat sealed or otherwise adhered to the upper edge of the one or more side walls 111 of the container 110.
  • the cartridge 100 is hence manufactured by providing the separating element 120, providing the pod 140, placing the pod 140 on a major surface 121 or 122 of the separating element 120, and forming the container 110 around the separating element 120 and the pod 140.
  • the container 110 is initially only partially formed.
  • the lid 113 may be left unattached.
  • a beverage additive may be placed on the bottom surface 112 of the container 110.
  • the separating element 120 is placed within the partially formed container 110, over the beverage additive if present.
  • the pod 140 is placed upon the separating element.
  • the container is then completed by attaching the lid 113 to the side walls 111 thereby enclosing the separating element and the pod.
  • the cartridge 100 is positioned in a beverage making machine, such as a single serving coffee brewer.
  • the machine includes at least two piercing tools 200 and 300, which are directed towards the cartridge 100, and operated to create at least one inlet and at least one outlet in the container 110, in such a way as to provide access to both the first and second portions 111 and 112.
  • the cartridge 100 is placed with the machine so that the lid of the cartridge is above the bottom surface of the cartridge, enabling the liquid to flow from the inlet to the outlet by a force at least partially due to gravity.
  • the pod 140 is supported in an advantageous position by the separating element 120, such that neither the first piercing tool 200 or the second piercing tool 300 contacts the pod 140.
  • a liquid water for example, is injected into the first portion 115 of the interior space 114 through an inlet created by the first piercing tool 200.
  • the water passes through the pod 140 under high pressure and at high velocity, saturating the contents and extracting the aroma and flavour of the contents. Since the pod 140 is supported by the separating element 120, it is believed that the pod 140 will not tear due to the force of the injected liquid or the force applied on the pod by its own increased weight when saturated.
  • the resulting beverage flows by gravity or another motive force through the drainage passages 123 of the separating element 120, into the second portion 116 of the container 110. If a beverage additive has been disposed between the separating element 120 and the bottom surface 112, the flavoured beverage mixes with the beverage additive. Finally, the beverage additive flows out of the outlet created by the second piercing tool 300. The beverage may then pass into a beverage collector of some form.
  • a cartridge 900 is shown in Figure 13 , comprising a container 110 that does not contain any separating elements or supporting elements to support a pod 140, such that the pod 140 can abut and lie on the bottom surface 112 of the container 110.
  • the absence of separating elements and supporting elements may simplify the manufacturing process and/or costs to make the cartridge 900.
  • at least a portion of the outer surface of the pod 140 may be made from material of sufficient resistance to tearing or piercing by a piercing tool (e.g. second piercing tool 300 shown in Figure 1 ).
  • a piercing tool e.g. second piercing tool 300 shown in Figure 1
  • only the portion of the pod 140 facing the bottom surface 112 of the container is made of material resistant to being pierced by the piercing tool.
