Definitions
- Portion capsules are known in many different versions.
- the hot water flows in either through the housing bottom of the outer capsule and out through the film again, which closes the opening of the capsule or, as in the embodiment of the invention, through the film and through a beverage outlet in the housing bottom of the outer capsule out again.
- the object of the invention is to provide a portion capsule of the type mentioned in the case of simple and inexpensive construction and assembly and high quality maintenance and aroma safety high reliability and this case a solid foam is produced in sufficient quantity. This also achieves a drip lock. It is also an object of the invention, a
- the capsule has weaknesses in its housing bottom, which open in the capsule interior fluid pressure, break or tear to liquid from the
- the inner plate Opens drink outlet out, so that the beverage produced can flow out of the capsule.
- the inner plate on the case back through bottlenecks to flow delays, turbulence, turbulence and pressure fluctuations, which lead to a significant increase in volume and improve the beverage foam.
- the capsule is particularly simple in construction and assembly. Furthermore, during storage, the contents of the inner capsule are kept unchanged for a long time, so that aroma losses do not arise.
- Capsule interior protruding annular projection protrudes, coaxial with the
- Capsule axis is arranged.
- the inner plate lies in the interior of the annular projection and can in this case project upwards over the annular projection in order to hedge with its outer edge in the annular space surrounding the annular projection.
- the outer edge of the inner plate rests positively in the annular space.
- Outer edge of the inner plate is perforated like a sieve. This will also be
- Optimal crema and drip arrest are also achieved when the fluid passages are channels, notches, and / or grooves in the outer edge of the inner plate. Also, this may be on the inner plate, a sieve or a perforated foil, which covers the inner plate.
- the capsule wall comprises or consists of a water vapor and / or oxygen-barrier material.
- the side wall and / or the bottom of the capsule may have two outer layers of a non-barrier material and have a barrier layer or barrier layer therebetween. It is also advantageous if the capsule wall is constructed in layers with a
- EVOH embedded ethylene-vinyl alcohol copolymer
- PLA biodegradable polyactide
- PVOH polyvinyl alcohol
- Fig. 1 shows an axial section through a portion capsule a first
- Fig. 3 to 8 are plan views of the housing bottom of the capsule without inner plate with - differently shaped weak points.
- the portion capsule 1 according to the invention is intended to be used in a beverage device, in particular in a coffee or tea machine, to provide a beverage, in particular coffee or tea from a substrate, granules or powder, which is located within the capsule.
- the portion capsule 1 is a cup-shaped capsule 1, in which the substrate, granules or powder is located.
- the capsule is opened to one side, in this case the inlet end 4, this opening 5 being closed by a film or foil resting on the inlet
- flange-shaped edge 5a of the capsule is stapled, so that the opening 5 is securely closed. This ensures that after a puncture of the film / film by a pipe, in particular a lance, the liquid penetrating through the pipe / lance in particular hot or cold water enters the capsule 1.
- the portion capsule 1 is formed by a pot-shaped housing made of plastic with a lower housing bottom 3 on which an annular cylindrical projection (annular projection 11) integrally projecting into the capsule interior projecting, whose axis is equal to the capsule axis 12.
- the inner diameter of the annular projection is equal to 1/3 to 3 A of the diameter of the input opening 5.
- the height or width of the annular projection is 2 to 6 mm.
- the capsule 1 has in its bottom 3 within the annular projection 11 at least one particular arcuate point of weakness 6 in the plastic of the capsule 1, which opens when the fluid pressure in the capsule opens, breaks or ruptures to liquid from the interior of the capsule to the beverage outlet. 7
- the weak point 6 consists of a tear line, so that when tearing a part of the housing bottom 10 breaks down.
- This vulnerability 6 may also be a tear notch, tear seam or other type of weakening.
- the bottom 3 of the capsule 1 has four, in particular circular arc weak points 6, which are evenly distributed over a circle, the center near the bottom edge and thus coaxial with Center axis 12 of the portion capsule is located.
- the plastic of the bottom has such a small thickness that the plastic breaks through / tears open due to the inside of the inner capsule
- the wall of the capsule 1 consists of a barrier layer or barrier layer of ethylene-vinyl alcohol copolymer (EVOH) or embedded polyolefin Intermediate layer of ethylene-vinyl alcohol copolymer (EVOH) or of a biodegradable polyactide (PLA) with embedded intermediate layer of EVOH or polyvinyl alcohol (PVOH).
- EVOH ethylene-vinyl alcohol copolymer
- PVA biodegradable polyactide
- PVOH polyvinyl alcohol
- the capsule 1 is produced by plastic injection molding. It is important that the plastic melt flows evenly from the center to the circular edge of the bottom when injecting the plastic in the middle of the housing bottom 3 forming cavity of the injection molding tool. But here are the
- the material has a greater thickness than in the region of the weak points 6, so that it is ensured that by the
- Fluid pressure within the portion capsule only the weak points 6 and not the thin spots 20 tear or break.
- the thin areas 20 have a greater radial width B1 than the radial width B2 of the weak points.
- four arc-shaped weak points 6 and four arcuate thin bodies 20 are arranged therebetween, which together form a continuous circle. Instead, three, five, or six weak points and thin points can each form a circle.
- the bottom 3 of the capsule, the weak points 6 and the thin spots 20 preferably have the following dimensions:
- FIG. 1 In the embodiment of FIG. 1 is within the annular projection 11 horizontally an inner plate 8 parallel to the bottom 3.
- This inner plate 8 fills the interior of the annular projection completely, so that it rests positively in the interior of the annular projection 11 and there covers the bottom 3.
- the cylindrical outer edge of the inner plate 8 is in this case close to the inner edge of the
- the thickness D of the inner plate 8 is 1 to 10 mm.
- Ring projection 17 downwardly, whose diameter is equal to or less than the diameter of the first annular projection 11, wherein the diameter of the second annular projection 17 is chosen so large that the weak points 6 are within the second annular projection 17.
- the axis of the second annular projection lies on the capsule axis 12.
- the second annular projection 17 is on the outside of a cup-shaped
- Plastic part 23 encompassed, which forms the lower outlet space 22 of the portion capsule 1 and has a lower central beverage outlet 7.
- the second embodiment shown in FIG. 2 differs from the first essentially in that the inner plate 8 has a larger outer diameter than the outer diameter of the first annular projection 11, so that the inner plate 8 protrudes radially all around the annular projection 11 and for this purpose an annular outer edge 8a forms, which fills the annular space 14 in particular form-fitting.
- the underside of the outer edge 8a sealingly rests sealingly on the housing bottom 3 and the inner plate 8 has on its underside a downwardly open annular groove 8b into which the annular projection 11 protrudes.
- the annular outer edge 8a has vertical channel-shaped 3 screen openings 16, which connect the upper side of the outer edge 8a to the underside thereof, so that the outer edge acts like a sieve.
- the underside of the outer edge 8a has radial flow channels 15, open into the screen openings 16.
- Liquid pressure in the interior of the portion capsule 1 flows the liquid from the interior into the sieve openings 16 and into the channels 15, then into the annular groove 8b to overflow the annular projection and below the inner plate 8 to reach the weak points 6, to open them, so that the liquid enters the outlet space 22 and the beverage outlet 7.
- the weak point is formed in FIG. 3 as part of a circular arc.
- the weak points 6 have the shape of a triangle, a wave, one or more teeth, an oval, a U or a V.
- an upper perforated plate (not shown) is mounted parallel to the bottom 3 and parallel to the upper covering foil which separates the inner space into a upper space and a lower space.
- the water passes through a lance and through the holes in the perforated plate, the water flows into the substrate storing the beverage substrate.
- the holes are arranged in the perforated plate at regular intervals, so that the water is evenly distributed in the substrate.
