Definitions

  • the present invention relates to a disposable device for preparing coffee, infusions and the like especially suitable for individual use.
  • This device dispenses with machines such as coffee makers or external resistance heaters.
  • the same device has a receptacle that allows dispensing with the cup or the like and allows it to be drunk in the same device.
  • plastic containers are configured in which by means of heat welding, induction, high frequency, ultrasound, laser, or other joining procedures, it is possible to configure ducts, filters, storage chambers, and distribution means that allow The device is functional.
  • Traditional coffee or tea brewing procedures consist of heating water and passing it through the dehydrated or ground product, as in the case of infusions or coffee.
  • the hot water extracts the soluble substances and the liquid obtained is the one that is used to be taken with sugar, milk or simply alone.
  • the most commonly used chamber consists of a bowl with handle that fills and empties easily. This bowl has a bayonet closure to close the cavity quickly and then be able to inject the hot water or fluid used under pressure to extract the soluble.
  • a machine is capable of supplying the pressurized fluid, usually very hot water, through an opening present or generated at the moment by drilling the injector.
  • a second perforation is the one that allows the output of the product already prepared to be subsequently poured into the user's cup. It is the machine that, when closing the cavity where the bag is housed, carries out the perforations by incision by means of an element or cutting elements such as, for example, the ends of the injection or outlet ducts.
  • This envelope contains the powder material that makes it possible to make coffee, for example, and consists of sheets welded together.
  • the injection of the hot fluid under pressure is what causes the envelope to open and exit the injected extraction fluid.
  • Its main claim therefore includes the presence of a channel that allows the arrival of the fluid - A - extraction, said channel being substantially perpendicular to the welding line in which it emerges.
  • the invention contemplates the injection of the extraction fluid by means of a machine that provides the necessary pressure.
  • said bag does not open by inserting the needle or the pointed element to the point of breaking the weld that closes said bag, but it is the pressurized water (under pressure) that initiates and completely opens said welding of the bag to allow the entry of the extraction liquid ".
  • the device of the present invention does not require a machine that provides sufficient pressure on the extraction liquid is because the same device incorporates the extraction liquid and it is the heating produced by a microwave oven that it provides the necessary pressure to carry out an integral extraction procedure either on coffee or on dehydrated material to obtain an infusion.
  • the device basically consists of two plastic sheets, rigid or flexible, joined together by heat welding, induction, high frequency, ultrasound, laser, or other joining procedures, setting up vities and different components that will be described later.
  • the two sheets are made of rigid plastic, it is possible to constitute at least two pieces joined by thermo-welding, along a suitably chosen line, which give rise to a three-dimensional body such as for example a vessel with an internal reservoir. In this case it is possible to incorporate additional sheets that would result in more cameras and communication steps.
  • the chambers are essentially configured in this rigid plastic and covered with a flexible heat-welded sheet along perimeter and other joining lines.
  • the chambers are configured by the heat welding lines.
  • heat welding it is by way of example and it is understood that any mentioned joining procedure such as induction, high frequency, ultrasound or laser among others is valid.
  • both sheets are rigid so that the cavities can be reproduced in one, in the two or alternate in one and the other according to design.
  • At least one first chamber must be present in this device to house the extraction liquid, usually water.
  • This first chamber communicates with a second chamber separated by a valve consisting of a weakening line that yields to pressure.
  • the second chamber is the substance from which its content is to be extracted by means of the extraction liquid: coffee, dehydrated plants to obtain an infusion or other more elaborate ones, for example with chocolate content and which also require passage of an extraction liquid.
  • This second chamber can communicate with more cameras arranged behind it to provide additional elements such as milk, either very solid liquid, or flow directly into an outlet channel that ends inside the cup or glass.
  • This device is designed to be attached to the vessel or cup, preferably hung from the edge by the outer or inner part, so that the vessel next to the device is inserted into the microwave.
  • Microwave radiation brings to the boiling point what has so far been called extraction liquid, for example water, so that in the chamber where it is stored the pressure is increased.
  • extraction liquid for example water
  • This pressure overcomes the resistance of the valve that keeps the chamber closed and allows its exit to the second chamber, which has the substance such as ground coffee or infusion plants.
  • This communication can be carried out by means of an intermediate chamber delimited on the one hand by the access valve to the extraction liquid and on the other by a filter.
  • This filter can be configured by means of heat-welding with no more than applying specific welding points, leaving steps or channels as a grid. stretches
  • This filter in addition to preventing the passage of the grain or ground substance such as coffee or the infusion plants backwards, favors that the hot extraction liquid enters along a passage line and not through a point in such a way that the liquid passes homogeneously through all the solid content without leaving areas that when compacted could even be left without even moistening.
  • a similar filter is arranged at the end of the second chamber so that only the coffee, the infusion, or the target product, already made and without particles, comes out.
  • Behind this second chamber is a communication channel that can start from a collection chamber that flows into the cup or glass.
  • a chamber is defined by a closed welding line that joins the two sheets.
  • plastic sheets can incorporate additional devices consisting of external elements and not by welding such as valves, filters or communication perforations.
  • any of the sheets is flexible, it is possible to integrate this type of device into the welding itself.
  • the union can be avoided by establishing a communication point. If this step is wide it constitutes a passage channel. If it is narrow, it can allow the passage of liquid but not particles of a smaller size. In this case, an alignment of narrow pass channels consisting of points where welding does not occur constitutes a filter.
  • the section weakened with a weld of this nature behaves like a valve that yields to a value of internal pressure greater than the permissible.
  • the cameras can be configured in it at least in the largest surface that delimits it in such a way that it will be enough to cover it with a sheet arranged according to a plane and joined by heat-welding at the points or lines of contact so that said chambers are definitively completed.
  • This last case is the one that allows the filters, valves and channels to be integrated more easily without defining more or less strong or interrupted welding lines to constitute them.
  • each of the sheets comes from the unwinding of a different coil. Both sheets converge until they are parallel since after joining each of them constitutes a face of the final device. Before joining, there are liquid and powder feeders that supply said components at the point where the sheets are sealed, it being appropriate to incorporate resuscitation means to prevent the sheets from staining by dripping or loss of dust making it difficult to welding .
