A. TITLE

PORTABLE MACHINE FOR SINGLE USE, TO PREPARE EXPRESS COFFEE, INFUSION BEVERAGES AND OTHER DRINKS.

B. TECHNOLOGICAL SECTOR

This is an embodiment of the invention which is related to a portable single-use machine for preparing espresso coffee, infusion beverages, macchiato, latte, cappuccino, tea, infusion of aromatic herbs, chocolate drinks, combinations thereof and other beverages , according to the substrate included in the infusion substrate container (14), which integrates in the same unit: the mechanisms that facilitate the infusion pressure of 0.9 to 1.0 Megapascals, the water temperature of 88 to 92 degrees Celsius, the time of extraction or elaboration of 20 to 30 seconds, the constitutive elements of the infusion, with total energy independence, of operation and of use, to offer a quality drink.

C. PREVIOUS TECHNOLOGY

This technology is based on portable machines to produce infusion beverages, especially espresso coffee.

These devices vary in size and functionality, where factors such as design, ease of use, external elements that must be contributed to the machine, among these: ingredients, energy sources or mechanical, are crucial to ensure that these devices can be considered fully portable.

Also influences in these devices the quality of the drink, where elements known by the experts of the technique, determine the sensory characteristics of the infusion, among these factors we find, the temperature of the water, which must be between 88 and 92 degrees centigrade, the water pressure, between 0.9 and 1.0 Megapascals, the time of extraction or processing time, which should be between 20 and 30 seconds, we must also take into account the quality of the water, the quality of the substrate where: the origin, roasting, grinding, freshness and adequate coffee conservation, allow to make a drink of excellent quality, all these conjugated elements guarantee the optimal properties of the infusion.

Among the developments of portable devices for infusion beverages is the patent application publication, BG602Y1, which uses as a heat source an element that activates a chemical reaction of anhydrous pyrolysis, which heats the stored water and gases produced by this reaction, by means of a membrane, press the water towards the substrate of the infusion. Which makes it difficult to maintain an adequate and constant water pressure, the correct elaboration of the drink demands a continuous pressure during 20 to 30 seconds.

There is also the publication of patent application US20090110776A1, where a heat exchanger unit is used that evaporates the water, transports it through a tube to a preparation chamber and elaborates the drink.

Procedure that does not guarantee an adequate and continuous water pressure, as well as the indicated temperature to perform the infusion, according to the parameters known to those skilled in the art. Another publication relating to portable devices for preparing infusion beverages, is the patent application publication WO9315641, in which it is described that by means of the increase of the vapor tension when the liquid inside the container is heated, it enters the container. tube that contains the powder of the infusion, flows inside it and the elaborated drink comes out to the cup. This method and device does not provide adequate pressure or time according to the parameters known to those skilled in the art.

There is also the publication of patent application DE4441226A1, which details a portable espresso machine, where the infusion water is heated by means of an electric or chemical heater at the base of the device, by boiling and increasing the pressure of water vapor, press it and go up through the filter and ground coffee, where it is forced by a riser pipe to the beverage container, reusable unit. This device does not provide the pressure or adequate time according to the values known to those skilled in the art, the components of the infusion must also be added externally.

The previous devices, due to their design, some based on water vapor, lack the pressure required for the production of cream, they present a lack of correct pressure of continuous operation, which is from 0.9 to 1.0 Megapascals, clarifying that it is normal that there is a variation of +/- 0.14 Megapascals, range in which professional espresso machines work. Due to these shortcomings, they are not able to reach the required working pressure, to extract aromatic substances and essential oils from roasted and ground coffee beans, which give the espresso its characteristic flavor and properties.

Also in these devices the times of infusion, and the pressure, are variable and independent, the optimal production of espresso coffee requires a high continuous pressure, during the entire extraction process of 20-30 seconds.

There is also the publication of patent application US20100098823A1, which describes a portable espresso coffee machine, which performs water heating in a boiler, by means of an electric heater and is pressed by a piston activated by electric motor, to pass through the coffee contained in the filter holder, it is a reusable device. This system is limited to an external electrical source for its operation, where we must also provide constituent elements of the infusion, restricting their work to the availability of them.

We have the application publication MX2009013680A, which consists of a portable infusion device, which consists of a container of compressed gas which provides the water pressure to make the infusion drink, is a reusable device. Water must be supplied externally to the device, as well as the infusion substrate to make the beverage.

In these last two publications, according to its design and due to the need to provide external elements to the device, it conditions the availability of the same for its correct functioning, which limits its characteristic of being portable. DESCRIPTION OF THE INVENTION:

We find according to the experts of the technique, that the lack of correct pressure and adequate time of continuous operation throughout the infusion process, does not extract the aromatic substances and essential oils from the roasted and ground coffee beans, which They give the espresso its flavor and characteristic properties, and neither does it allow the production of cream.

Also when having to contribute external elements to the device for its operation, such as: energy sources and constitutive elements of the infusion, which according to their availability, restrict their particularity of being portable.

For the above there is a need in the art for a portable single-use machine, to prepare espresso coffee, easy to use, which includes all the mechanical and operating elements, which allows us to offer an adequate working pressure, with temperature and extraction time according to those known to those skilled in the art, which incorporates all the constituent elements of the beverage, with total energy independence, of use, that produces quality espresso.

Therefore, the present invention is an embodiment of the invention that refers to a PORTABLE MACHINE OF A SINGLE USE, TO PREPARE EXPRESS COFFEE, INFUSION BEVERAGES AND OTHER BEVERAGES, where to include all the elements and constituent ingredients of the final product, with total energy, mechanical and utilization independence, with pressures, suitable temperatures and times of operation, in the same unit, overcomes and corrects the problems and disadvantages of the prior art mentioned here, elaborating a quality espresso coffee.
