In the example of Figure 2, the circumferential wall is substantially rigid -10-. The circumferential wall may comprise, for example, a plastic material and may be formed for example by injection molding, vacuum forming, thermoforming or the like. In the example of Figure 2, the bottom wall part -12- of the wall -10- circumferential. In this example, the inlet filter -34- is formed by a series of inlet openings -24- in the bottom wall -12-. In this example, the number of inlet openings 24 is distributed substantially the entire bottom wall -12-. In the embodiment shown, the fluid is supplied to the extractable product -20- through the series of inlet openings -24-, which causes humidification of the extractable product -20- substantially the entire cross section of the capsule -2 -. Thus, a very homogeneous supply of fluid to the extractable product is obtained -20-. Thus significantly reducing the risk of preferential paths occur through which the fluid flows through the extractable product -20-. In another embodiment, additional openings can be provided in the circumferential wall -24- -10-, preferably near the bottom wall -12-, so that the part of the inlet opening may be disposed along the wall -12- line and along the circumferential wall -10-.

In another embodiment, which can be used in addition to or separately from the previously described embodiments, the system -1- of figure 2 comprises some means -128- for drilling the cover intended to drill the cover -116- of the prior art capsule -102- when the cap -116- presses sufficiently against the cap-drilling means -128- under the influence of fluid and / or beverage pressure in the capsule -102 to create, at a minimum, an outlet opening 130. through which the beverage can pass from the prior art capsule 102. -36- The output filter may be arranged to have sufficient tear resistance not to be pierced by means -128- drilling lid under the influence of the pressure inside the capsule 2. Alternatively, or additionally, the filter output resistance -36- form the sufficiently low flow of beverage leaving the capsule -2-, so that the output filter -36- is not pressed against the media - 128- of drilling cap hard enough for drilling by said piercing means -128-. Preferably, the lid 12 may remain intact or may be opened by displacement of moving parts. The output filter means 36 and drilling -128- cap may be adapted to each other such that the capsule 2, in use, is not pierced by the piercing means -128-, but to the contrary, openings are formed by the displacement of the moving parts of the capsule 2.

According to one embodiment of the invention, the capsule 2 comprises an exit filter 36, comprising outlet openings -30- through which can pass the beverage from the capsule 2. As will be explained later, the capsule may be provided with opening portions to open outlet openings of said outlet -30antes or during use.

In the example of Figure 2, the exit filter 36, forming a part of the outlet opening capsule 2, through which the beverage, here coffee, can drain from the capsule, It is formed by a porous sheet, such as filter paper. In this example, all of the cover -16- is formed as the exit filter -36-. In the example of Figure 2, the capsule 2 comprises a rim -38- which extends outward at the second end -18-, in which the cover -16- is fixed to the edge extending -38- out, for example by gluing, welding or the like. Therefore, in this example the exit filter 36, i.e., the porous sheet, is attached to the flange -38- extending outward.

In this example the exit filter forms a sheet -36- substantially continuous fluid-permeable extending substantially the entire second open end -18- of the capsule 2. Thus, fluid can pass from the capsule 2 over a large area. Therefore, a very homogeneous beverage outlet is obtained from the extractable product -20-. Thus significantly reducing the risk of preferential paths occur by passing the fluid through the extractable product -20-.

In one embodiment, you can be chosen parameters output filter -36- of the capsule 2 of the system 1 so that the output filter -36- is not tears or breaks, for example, has sufficient resistance to tear and / or form a resistance to the sufficiently low flow not be frayed or broken. It will be appreciated that the lid and / or the exit filter may deform against -36- means for piercing the lid, although not break or tear. When the outlet filter -36- is made, for example, based on filter paper, the parameters of the filter paper such as density, thickness and / or PE content can easily be chosen, to achieve an outlet filter - 36- which has a sufficiently high tear resistance and / or achieve a sufficiently low resistance to the passage of fluid. Alternatively, when the outlet filter -36- is formed, for example, of a polymer film provided with a series of outlet openings, the parameters of the polymer sheet, such as density, thickness, number of outlet, dimensions and / or shape of the outlet openings can be easily chosen to achieve the third wall having a sufficiently high tear resistance and / or to achieve sufficiently low flow resistance.

In the example of Figure 2, means -128- drilling lid are shown provided with shaped tips sharp teeth intended to pierce the cover. It will be appreciated that, alternatively, the piercing means

-128- may have blunt drilling surfaces, for example, as indicated by the dashed lines in Figure 2. In this embodiment, the prior art capsule -102- can be drilled, however, by the blunt-shaped drilling means -128-, for example when the cover -116- consists of a laminar sheet of

ES 2425956 T3 aluminum. Parameters output filter -36- of the capsule 2 of the system 1 according to an embodiment of the invention, can be chosen such that the exit filter has -36- tearing resistance sufficiently high and / or has a resistance to the sufficiently low flow which does not tear or break it. It will be appreciated that when the cap drilling means is blunt-shaped, the parameters of the outlet filter can be chosen appropriately for these blunt-shaped drilling means. When the drilling means are blunt in shape, the outlet filter can be, for example, thinner than when the drilling means are sharp, while ensuring that the outlet filter has a sufficiently high resistance to tearing and / or obtaining a resistance to the sufficiently low flow not be frayed or broken.

It is possible that the means for drilling the lid comprise ribs against which the lid abuts in use. These ribs may be formed by means of drilling -128- bluntly as shown by the dashed lines in Figure 2. Said ribs can form at least 10%, possibly at least 25% of the part of the surface of the container -106- which, in use, coincides with the part of the surface area of ​​the lid -16- superimposed on the second end. -18- open. Thus, in use, the cover -16- can be supported by said ribs at least 10%, preferably at least 25%, of the part of the surface area of ​​the lid overlying the second -16- open end -18-. As indicated, the cover of the capsule 116. Prior art 102 can be drilled by the mentioned ribs, while the parameters of the exit filter of the capsule -2- -36- of the system -1 - according to an embodiment of the invention, they can easily be chosen such that the exit filter -36- has resistance to tearing sufficiently high and / or has a resistance to the sufficiently low flow not be torn or broken. It will be appreciated that when the piercing means of the cap comprise ribs, the parameters of the exit filter may be chosen to appropriate to said piercing means of the cover.

In the example of Figure 2, the ribs comprise edges which are not sharp. In this example, a radius of curvature of the edges is approximately 50 pm, although other radios can be provided, such as 100, 200 or 500 pm. The prior art capsule -102-, however, can be drilled by the blunt-type drilling means -128-, for example, when the cap -116- consists of an aluminum foil. It will be appreciated that when the piercing means of the cover comprise edges which are not sharp, the parameters of the exit filter -36pueden be chosen to suit such piercing means of the cover. Parameters output filter -36- of the capsule 2 of the system 1 according to an embodiment of the invention, can be chosen so that the output filter -36- has sufficient breaking strength and / or achieving a low enough resistance to flow to avoid breaking or drilling.

It is also possible that the ribs of the drilling device -128- of the lid have a convex top against which the lid abuts -16-. Therefore, when the lid -16-, in use, is pressed against said ribs, the surface area on which the lid is supported by the ribs increases, thereby reducing the local pressure exerted on the lid by said ribs. . Therefore, it is possible to easily achieve that the cover -12- in use does not break or tear and remains intact. Before the capsule -2- is placed in the container -106-, the capsule -2- can be sealed in such a way that the extractable product -20- can remain intact until the preparation of the drink.

The material of the capsule 2 may comprise cellulose, paper, cotton and / or starch based products. For example, the capsule material may comprise -4- biodegradable material. In another embodiment, the capsule material may comprise -4- plastic. The bottom wall 12 and the cover -14- may comprise an input filter and an output filter 34, 36, respectively. -4- capsule, for example, can be formed by injection molding, vacuum forming, thermoforming, compression molding or the like. In the above description, the integral shaping can be understood by the fact that the respective parts of the capsule 2 are shaped approximately the same time in a forming process. For example, the respective parts can be molded in the same mold. In another embodiment, different parts can be thermally bonded, glued or welded to form the capsule 2.

At least one of the filters 34, 36 may comprise a porous fluid permeable sheet. At least one of the filters -34-, -36- may comprise filter paper and / or polyethylene (PE) fibers. Substantially the entire surface of the bottom wall 12 and / or the cover -14-, at least regarding the part extending inside the circumferential wall -10-, may be permeable to fluids. The filters 34, -36pueden also be made so as to be permeable when water is supplied at a specific pressure, for example a pressure of 6 bar. For example, low pressure fluid does not pass through the filters 34, -36-. At least one of the filters 34, -36- can be flexible. The filter -34-, -36- may comprise a polymer film.

3A-D figures show a capsule having a first movable part -200- for opening an opening portion -9- input and a second moving part 202 to open part of outlet opening -11-. In the example, the opening portions -9-, -11- may comprise webs -204-, -206-, respectively. In the example shown, the moving parts -200-, 202 are arranged to open the respective opening portions -9-, -11- by a drilling action.
