- the state of the art includes several solutions relating to single-use capsules for preparing edible products, such as espresso coffee, tea and other soluble products.
- Capsules consist of small containers that contain the edible product, used in compatible machines and that allow the quick preparation of the edible product.
- the capsule comprises two elements: a base cup and a lid.
- the base cup has a bottom that is either fully closed or pre-perforated, in either case being punctured by the punches of the edible product machine where the capsule is placed.
- the mouth of the capsule cup has a peripheral flap that then serves as a surface for gluing the lid, which generally consists of silver foil, aluminum foil, filter paper or micro-perforated plastic.
- the capsules used in edible product machines after being placed in the machine, are perforated on both sides by a mechanized system of punches, in which some are perforated when closing the lid of the machine compartment where the capsule is placed and others They are pierced by a punching mechanism that is incorporated into the machine and is driven by an electrical system, which ensures the pumping and heating of water.
- capsule coffee machines that work with the help of a lever that opens an extraction group made up of a container where the capsule is housed after its insertion into the machine and a sealing lid that breaks or opens the capsule. capsule and add hot water. Once filled and under the effect of high pressure, the capsule opens and releases the water mixture that passes through the edible substance to the outside of the machine. At the end, the capsule is expelled by repeating the opening movement of the lever.
- capsules made up of numerous shapes and materials (paper, plastic and metal-aluminium), which means they obtain different compositions that influence their performance in preserving the edible product.
- Many currently existing capsules are not recyclable or difficult to recycle.
- Aluminum is the best material for the production of capsules, as it ensures more effective maintenance of properties. of edible products and also has the advantage of being "infinitely recyclable", which is quickly put into a new production cycle, and is a very light material.
- this material presents rigidity and resistance characteristics very different from those of plastic, which may bring some disadvantages in terms of its plastic deformation, when applied to the part of the lid that is subject to opening by the machine.
- Document WO 2021/122676A1 discloses a disposable capsule for preparing a beverage made of metallic material, such as aluminum, specifically an aluminum alloy of the 3xxx series, and preferably aluminum alloy 3004 or 3104. It is further stated that the thickness of the aluminum alloy at the bottom and side wall of the capsule is between 50 and 100 micrometers and the thickness of the lid is between 20 and 60 micrometers.

- the passageway has a region of weakened material that is adapted so that it ruptures under a given flow pressure. It is also mentioned the existence of a projection element that exerts a lever-type mechanical force on the region of weakened material.
- the circular cap-type construction element that undergoes the perforation is made of plastic material.
- Document EP 2465793B1 relates to a capsule for infusion products comprising a plastic cup structure and a plastic lid arranged to close said cup structure.
- This disclosure focuses on the configuration of the edge of the structure that receives the lid; and in the configuration of the lid, which conforms to the configuration of the edge of the structure.
- the importance of the aforementioned configurations is related to the usefulness of creating an element to receive possible molten material resulting from the welding (by ultrasound) of the lid to the structure.
- the document also states that the central area of said lid, which serves as an inlet for water from the beverage preparation machine, has a peripheral area with a reduced thickness.
- Document PT 107043B discloses a capsule comprising a part of the lid that can have at least one break formation facilitated for the entry of water.
- the lid has at least one break formation that facilitates the entry of infusion water into the container.
- the container, lid, base and piercing element are made of plastic while the protective element is an aluminum plate.
- the perforation of the capsule lid is not of a mechanical type, but only of a hydraulic type.

- break line is understood as a local discontinuity caused by the removal of material in the target object. Such discontinuity is called a line due to the reduced value of the ratio between its radial dimension and longitudinal dimension (width much smaller than length). Said break line can take on different forms in addition to the obvious linear or rectilinear shape.
- the target object is a flat opening surface (4), formed from aluminum material, on which break lines are arranged in accordance with the description below. It is important to note that the break lines, although they result from the removal of material on the surface (4) of the flat opening, cannot change its tightness condition until the moment the capsule is opened by a compatible machine.
- break lines are not through slots opened in the material of the flat opening surface (4), but only lines defined by partial removal of material from that opening surface (4), which allows, at the same time, to maintain the sealing of the flat opening surface (4) and creating a locally weakened region with regard to the tensile strength of the material of the flat opening surface (4). Therefore, any break line is well defined by its width, length and depth, the latter dimension corresponding to the thickness of material removed from the flat opening surface (4), so the depth of the break line is directly related to the thickness of the opening surface (4) in the concrete where the break line is located.

- the edges of this structure are rounded to allow greater ease of breaking when pressed by the opening element (7) of the machine for preparing soluble edible products.
- any X value presented in the course of the present description should be interpreted as an approximate value of the actual introduce deviations from the real value. Therefore, for example, the reference to "80%” means a value of "around 80%".
- the value ranges presented in this description are intended to provide a simplified and technically accepted way to indicate each individual value within the respective range.
- the expression “15% to 25%” or “between 15% and 25%” means any value within this range, for example 15%; 16%; 17%; 18%; 19%; 20%; 21%; 22%; 23%; 24%; 25%; or others, for example including a decimal place.
- the configuration of said top part (23) of the capsule of the invention provides greater resistance to the force exerted by the machine's opening device, which occurs when the capsule is opened by the coffee machine, thus avoiding excessive deformation of the top of the capsule. which could prove to be counterproductive in relation to its effective opening.

- Figs 27 to 32 represent the embodiment of the capsule (1) of the present invention with four elements (8) protruding on the flat opening surface (4), which when subjected to the force of the opening element (7) of the edible products machine, are torn by the peripheral contours that are in contact with the opening surface (4), allowing the passage of water.
- Figs 33 to 37 represent the embodiment of the capsule (1) of the present invention with three protruding elements (8), juxtaposed with each other, on the flat opening surface (4), which when subjected to the force of the opening (7) of the edible products machine, are torn by the common break lines, allowing water to pass through.
- the aluminum capsule (1) for a soluble edible product comprises a closed container (2), containing an individual dose of a soluble edible product, which is delimited by a side wall (21), a bottom part (22) and a top part (23).
- the capsule When in use, the capsule is placed in the capsule compartment of the soluble edible product preparation machine, e.g. espresso machine.
- the capsule is kept in said compartment and the opening element (7) of the machine is activated, which will pierce the capsule in the top part (23), specifically in the six break lines of the flat opening surface (4) (Fig. 21 ) .
- the water to make the espresso is then injected under pressure into the break lines (5) of the capsule, mixing with the coffee powder present inside the capsule.
- the pressure can be relatively high and can reach around 16 bar. This pressure causes the pre-opening (6) to open through which the espresso coffee flows uniformly directly through the opening (6) into the espresso receiving container.
