  • pods and capsules represent a practical and fast method to prepare an espresso, eliminating the annoying phase of grinding and dosing the coffee beans.
  • these systems face a major challenge: replicating the quality of the cream obtained with traditional methods.
  • the dense and compact foam not only adds a pleasant texture to the drink, but retains and amplifies the aroma in every sip. This advantage is further enhanced by the single-serve portion, which preserves taste and integrity for longer than traditional methods.
  • the capsule described here is designed for espresso machines and is used to extract beverages from a particulate substance using water under pressure.
  • the capsule consists of a main body that includes a cup-shaped part and a lid.
  • the cup has a base, a side wall, and an upper edge on which the lid is fixed, defining an internal volume that contains the particulate substance. This volume is equipped with filtering means to retain the particulate substance and percolate the fluids.
  • a distinctive feature of the capsule is the presence of a valve mounted on the base of the cup, which opens elastically under the pressure of the fluids during the beverage extraction phase, allowing the passage of the fluid.
  • This valve made of a resilient material with at least one normally closed slit or orifice, isolates the inside of the capsule from the outside environment and retains fluid residues once extraction is complete. When the valve is open, it facilitates the formation and stability of the cream in the extracted beverage.
  • the capsule may also include obstacles to the flow of fluids inside the base to interrupt the direct flow.
  • the valve closes automatically when the fluid pressure decreases at the end of the extraction, retaining the residues inside.

  • Document US3088826 discloses a method of preparing coffee that involves the use of a fluid circuit with a confined pressure extraction zone, capable of withstanding the pressure of the water passing through it, and forcing the hot water through coffee powder contained in this extraction zone.
  • the steps consist of packing the coffee in a rigid container when it is freshly ground and sealing it to keep the freshly ground coffee out of contact with oxygen until immediately before the extraction operation, and constituting the original rigid container as the aforementioned confined pressure extraction zone, which includes the steps of perforating it and connecting the perforated container in the aforementioned fluid circuit, using the rigidity of the container to make a sealed connection in the fluid circuit.
  • Document W01994002059A1 discloses a device for extracting edible substances contained in a sachet, using water under pressure.
  • This device consists of two main elements: the first element has a base with raised portions and a cavity, while the second element has a cavity that couples with the edge of the first element.
  • the base of the first element allows the sachet to be torn when pressed against the raised portions, allowing the extract to flow through the holes in the base.
  • the second element has a surface with a convex and a concave part, which couple with the edge of the first element, forming an extraction chamber together.
  • the device also includes means for piercing the sachet and introducing water into the chamber for the extraction of the edible substance.

  • This document discloses a single-dose capsule and a piercing device.
  • the capsule has a base that forms a recess suitable for accommodating an ejection spring.
  • This recess creates an annular channel whose base is suitable for being perforated by a plurality of tips provided in the perforation device. These tips have an inclined and perforated side that connects them with outflow channels made inside each tip.
  • the piercing device tears the sheet that forms the base of the capsule, in particular the base of the annular channel, the partially torn sheet rests on the tip, creating a positive labyrinth for the extracted fluid, but at the same time it rests on the holes made in the inclined side of each tip and obstructs the passage. Therefore, there is a need to create a solution that allows the laceration of the base and the creation of a labyrinthine path for the extract, but at the same time avoids the obstruction of the outflow openings of the extract.
  • the hole indicated with the reference T1 is placed on the top of the protuberance indicated with the reference 20 and, due to its particularly small size and elevated position with respect to the openings of the outflow channels indicated with the reference 22, it is only useful for evacuating any air that forms between the base plate 17 and the base 11 of the capsule 1 (see [0052]).
  • Document - EP2425752A1 discloses a container that is designed to contain a dosed amount of a solid product, from which a beverage can be extracted.

  • This and other purposes are achieved by a machine according to claim 1, as well as an spent capsule according to claim 15.
  • a machine for extracting a beverage or extract fluid from a substance contained in a capsule, such as a single-dose capsule is designed with different features to optimize the extraction process.
  • the machine includes at least one extraction chamber, which in turn includes two half-chambers. These half-chambers can move away from each other to open, allowing the insertion of the singledose capsule in one of the half-chambers. Once inserted, the half-chambers come together to close, forming a closed extraction chamber.
  • a first piercing device is associated with the first half-chamber. This device is designed to pierce the single-dose capsule and allow the inflow of an extraction fluid into the capsule. The extraction fluid interacts with the substance contained in the capsule, extracting the extract fluid.
  • a second piercing device is associated with the second half-chamber. This device pierces the single-dose capsule to allow the extract fluid to flow out during the beverage extraction phase. The extracted fluid, once it has been collected from the substance in the capsule, passes through an outlet passage located downstream of the second piercing device.
  • the second piercing device is equipped with at least one cutting element.
  • This cutting element includes an end portion that is tapered and ends with a narrow edge, which has a circular arc shape. This tapered edge partially surrounds the outlet passage, ensuring effective and precise perforation of the capsule to allow the correct flow of the extract fluid.
  • the machine's design allows for efficient and controlled extraction of the extract fluid from the single-dose capsule.
  • the semi-chambers that close around the capsule ensure that the capsule is correctly perforated and that the extraction fluid can enter and exit optimally.
  • the presence of well-designed cutting elements allows for clean and precise perforation, minimizing waste and ensuring that extraction takes place evenly.
  • This machine represents an advanced technological solution for extracting beverages from single-dose cartridges, optimizing both the capsule insertion process and the beverage extraction process.
  • the second piercing device of the beverage extraction machine has a sophisticated structure that guarantees effective piercing of the single-dose capsule.
  • This device includes at least one cutting element, which is a crucial component for the entire extraction process.
  • the cutting element is designed with a specific end portion that plays a fundamental role in the perforation of the capsule.
  • the end portion of the cutting element is tapered, which means that it gradually narrows towards the tip. This tapering is essential because it allows the cutting element to penetrate the capsule with greater precision and less resistance.
  • the tapered tip ends with a narrow edge, which can be sharpened like a knife. This sharp edge is shaped like a circular arc, a shape that offers various advantages in terms of effectiveness and cleanliness of the cut, avoiding tearing and slitting the outer wall of the capsule.
  • the upper arched edge of the cutting element also performs a dual function: on the one hand, it acts as a knife to cut the outer wall, on the other, it provides optimal support for the filter placed inside the capsule and filtering the particulate material from which the extract is obtained, ensuring integrity despite the pressure exerted by the pressurized coffee above it.
  • the tapered edge at least partially surrounds the outlet passage, which is the hole through which the extract fluid is released towards the collection cup or cup.
  • the circular arc shape of the sharp edge ensures that the perforation is clean and precise, minimizing the possibility of tearing or damaging the capsule and the internal filter that could compromise the efficiency of the extraction and pass granular material into the extracted fluid.
  • the configuration of the tapered edge surrounding the outlet passage allows a constant and controlled flow of the extract fluid to be maintained. This design minimizes the risk of blockages or interruptions in the flow, which could adversely affect the extraction and quality of the beverage.
  • the second piercing device with its cutting element is designed for optimal extraction, representing a fundamental component of the beverage extraction machine.
  • the precision and effectiveness of the perforation ensure that the extraction process is optimized, helping to produce a high-quality beverage with each use.
  • the attention to detail in the design of the cutting element reflects the commitment to improving the efficiency and reliability of the entire machine.
  • the carefully designed cutting element guarantees high performance and reliable operation over time.
  • the second piercing device of the beverage extraction machine is an essential component that guarantees effective piercing of the single-dose capsule.
  • This device consists of a hollow, internally shaped truncated cone body.
  • the body design includes an outer wall shaped like a truncated cone and a tapered inner wall that narrows towards a preferably, but not necessarily, sharp edge.
  • the end portion of the sharp edge terminates in an arcuate shape, which is crucial to ensure precise and clean piercing of the capsule during the extraction process.
  • the body of the piercing device is traversed by a diametrical channel, which divides the body itself into two opposing cutting elements. These cutting elements partially surround the outlet passage, thus creating an effective structure to pierce the capsule and allow the extracted fluid to flow freely.
  • the intersection edges between the cutting elements and the diametrical channel are rounded or flared, ensuring that the perforation is clean and precise. This measure significantly reduces the risk of blockages or hitches during the flow of the extracted fluid or irregular laceration of the capsule wall.
  • the flared or double conical shape of the components offers multiple advantages, including: [0050] • support against the collapse of the external wall; the flared geometry helps to counteract the strong hydraulic pressures that could cause the external wall to collapse, ensuring the structural stability of the device.
  • the conical shape facilitates the ejection of the capsule from the chamber after use, minimizing the possibility that the components remain attached to the perforator, creating obstacles or malfunctions.
  • the walls that delimit the diametrical channel are inclined towards the outlet passage, creating a natural guide for the extracted fluid. This configuration allows the fluid to flow without obstacles, improving the overall efficiency of the extraction process, then facilitating the detachment of the capsule used by the perforator after use.
  • the outlet passage can be unique and located in the center of the drilling device, and is delimited by a side wall that ends with an inlet opening edge and an outlet opening edge.
  • the drilling device can be integrated with the second extraction half-chamber or can be a separate piece.
  • this device comprises a plate from which the cutting elements extend and a stem that delimits the outlet passage.
  • the plate also acts as a stop element, ensuring that the piercing device aligns correctly with the extraction half-chamber during operation.
  • the stem can be inserted into a through opening of the extraction chamber and can be sealed with an O-ring to ensure a hermetic seal or screwed for greater stability.
  • the cutting elements can have different shapes and sizes, and can have openings that form recesses or grooves. These openings, obtained in the cutting elements, can be parallel to the outlet passage, further facilitating the flow of the extracted fluid.
  • the cutting elements can be configured in various combinations, with one or more openings for each element, thus adapting to different drilling and flow needs.
  • the sharp edge of the piercing device is delimited externally by a truncated cone portion and internally by a wall that converges towards the outlet passage.
  • This configuration ensures efficient perforation of the capsule, ensuring that the internal filter of the capsule is deformed without being torn. This is particularly important for maintaining optimal filtration of particulate substances, such as ground coffee.
  • the second piercing device is designed to ensure precise and controlled piercing of the single-dose capsule, optimizing the fluid extraction process and improving the overall quality of the extracted beverage.
