MANUAL COFFEE MAKER [001] The present invention relates to an espresso machine using manual pressure. Through simple manual operation different textures, aromas and flavors of coffee can be extracted.

[002] Therefore, the present invention describes a system that creates pressure by screw leaving total control for the user, without needing extra supplies like compressed air cartridges and paper filters. In this way, the user chooses the style of drink, from espresso to filtrate, in addition to being able to take the coffee maker anywhere, from camping to the office, and can use hot or cold water. The split-piston system allows the user to fill the compression chamber without turning the coffee maker or any other action. [003] For home use, a base was created for fixing the coffee maker, making use more comfortable.

Field of Invention [004] Espresso is a method of preparing coffee by passing hot (not boiling) water under high pressure through ground coffee. Traditional espresso coffee, in an industrial machine, is made under a pressure of 9 to 10 atmospheres (atm).

[005] The objective of the present invention is to provide a durable, practical product, which does not need electric energy and which produces little waste. Because it does not need electricity and a filter, it is portable.

[006] This invention relates to manual equipment for making a drink by filtering liquid through ground coffee beans. More

2/9 in particular, the invention is directed to improvements in a coffee maker in which the hot replacement water is passed through the ground coffee in an infusion chamber.

Background to the Invention [007] Coffee makers are culinary tools designed to prepare coffee. However, with the invention of different types of coffee machines, coffee makers started to be used mainly for heating water.

[008] The traditional coffee maker is a tapered metal container with a handle and lid suitable for use over a flame.

[009] The appliances for preparing coffee are in different configurations: coffee machine using water pressure pump, vacuum coffee machine, moka pot (Italian coffee maker), drip coffee maker using filters, containers with French model plunger, etc.

[010] In addition, certain portable coffee makers, currently sold on the market, fail to achieve a high level of beverage. They use compressed air cartridges, or a manual pumping system to create internal pressure. Both methods do not allow personalization of internal pressure, nor do they achieve higher quality levels.

[011] The following documents present the various inventions whose structure is complex, with high production costs and low efficiency in extracting the flavors and aromas of coffee.

6/9 is tapered so that the espresso comes out through an exit hole in the center of the basket housing.

Foundations of the Invention [021] Currently, machines pressurized using individual sachets or capsules containing coffee powder are widely used and practical, but they are harmful to the environment. Although the subject has been discussed for some time, the market continues to grow: in 2015 alone, 7,000 tons of this type of coffee were sold, with a market estimated at R $ 1.4 billion.

[022] The problem with the capsules is not only the amount of waste, but also the fact that they are not recyclable. To manufacture them, a special plastic, known as Plastic seven, is used. In addition to this material, the capsules are formed by a filter, grains and the aluminum top. Germany's second largest city has banned the purchase of coffee capsules by government agencies. The measure introduced is part of a major public management effort to reduce the amount of solid waste thrown into the environment.

[023] In addition to the idea of more conscious consumption, the invention bets on a mechanical system. Simply put the coffee powder in the filter holder, add hot water and turn the handle.

Detailed description of the invention [024] The coffee maker consists of a compression chamber made of stainless steel or brass, a split piston (Fig. 1 / F) that slides inside the compression chamber (Fig. 1 / L) compressing the water over the coffee that is housed inside the Filter (Fig. 1 / I).

[025] Water is deposited inside the coffee maker through its upper opening, passing through the upper funnel (Fig. 1 / M) and the Fixed Thread.

[026] The split piston (Fig. 1 / F) consists of two pieces in stainless steel or brass, when the piston rises close to the fixed Nut (Fig. 1 / D), a passage opens between its two parts, causing the water that is inside the Compression Chamber (Fig. 1 / L) to pass through the piston, coming into contact with the coffee that is in the filter (Fig. 1 / L).

Petition 870160071186, of 11/29/2016, p. 20/27

8/9 [027] The filter is housed inside the Filter holder (Fig. 1 / G), which is threaded to the compression chamber (Fig. 1 / L).

[028] When the piston descends, the resistance of the O-ring that is pressed against the wall of the compression chamber leaves the piston slightly stuck in its position causing the Piston Cap (Fig. 1 / J) which in turn it is moved by the Threaded Axis (Fig. 1 / E), close the passage between the two through another seal, preventing water from rising, thus it is forced to pass over the coffee. These two parts slide into each other, and are secured by a screw fixed to the piston cover (Fig. 1 / J), preventing them from disassembling. This movement is driven by the Threaded Axis (Fig. 1 / E), which revolves around the Fixed Nut (Fig. 1 / D). The turning movement is made by the Hand Crank (Fig. 1 / C), which is moved by the user's hand. Depending on the speed of the rotation made by the user, the split piston (Fig. 1 / F) rises and falls faster or slower, creating more or less pressure against the coffee in the filter.

[029] The Compression Chamber (Fig. 1 / L) is coated with thermal insulating material (Fig. 1 / K) so as not to burn the user's hand, and can be made of wood, leather or some plastic polymer.

[030] The threaded shaft (Fig. 1 / E) rotates on top of the piston cover (Fig. 1 / J), sliding over a plastic piston washer. In turn, it remains attached to the Piston Cap (Fig. 1 / J), using screws or locking pins that allow it to rotate in a false way, but keep it locked in the vertical movements of up and down.

Petition 870160071186, of 11/29/2016, p. 21/27

9/9 [031] The Crank (Fig. 1 / C) in turn is fixed to the Threaded Axis (Fig. 1 / E) by the Moving Screw and at its other end there is the Handle (Fig. 1 / B) that rotates around the Handle Pin.

[032] The Filter Holder (Fig. 1 / G) that houses the Filter (Fig. 1 / I), has at its base an opening where two pieces fit together. One of them is the Lower Funnel (Fig. 1 / H), which concentrates all the coffee that comes out through the holes in the Filter and directs them to the only outlet, avoiding splashes that commonly fall out of the cup or cup. It is fixed next to the filter holder (Fig. 1 / G) by pressure made by the rubber O-ring, which is compressed when fitting the two pieces, making it easy to disengage. The other piece is the Cup Glove (Fig. 1 / N), made of plastic, rubber or silicone. It fits in the lower opening of the filter holder (Fig. 1 / G) and the cup fits by pressing on it, so that the preparation of the drink can be done in a more comfortable way, since the user does not need to keep the machine in position above the cup.

[033] The Base is made of metal, where the coffee maker is fitted without the Filter Holder on the Bezel, and is fixed by pressure made by the Bezel Screw. After tightening, the filter holder is screwed into the compression chamber. This fixation of the coffee maker to the base, makes the preparation more practical due to the weight of the set, in addition to making the drink will always be poured in the same place.

[034] The Bezel is attached to the Base Shaft by a screw and its height is adjustable in the length of the Base Shaft.
