Description

Capsule for beverage ingredient

Technical field

The technical solution relates to a capsule for a beverage preparation ingredient.

Prior art

At present, various types of capsules intended for the production of beverages in devices injecting hot pressurized water or steam into the capsule, which contains an ingredient for preparing a beverage, are currently known from practice as well as from the patent literature. The ingredient for the preparation of the beverage is closed in the described type of capsules by means of foils, usually aluminum. In front of the bottom of the capsule there is an opening plate with elements for perforating the lower sealing foil. When pressurized water or steam is introduced into the capsule, which is done by inserting an injection needle through the upper sealing foil, the ingredient begins to mix with the water and also the lower sealing foil is perforated by the pressure on the opening plate. The opening plate is provided on the one hand with opening means, which are usually spikes, and also comprises openings for the flow of liquid and also in some cases also valve means, which have the task of preventing further leakage of liquid or liquid. beverage after stopping the supply of pressurized water or steam. The opening plate, on the side opposite to the opening means, is usually provided with a labyrinth, usually formed by a system of partitions, which serves to mix the ingredient with water before the finished beverage flows out of the outlet end of the capsule.

European patent application EP06011671 describes a capsule with an opening plate comprising a valve means and perforating means.

WO2008 / 116818 describes a capsule with a valve means on the plate and also with perforating means. In addition to these means, the plate also contains capillary openings. Another European application EP08100448 describes a capsule wherein the valve means located on the plate cooperates with the wall of the capsule. Likewise, circles with recesses are arranged on the underside of the plate, i. labyrinth. Similar solutions are also described in applications EP05104016 and WO2007 / 141202. The described solutions also comprise a valve means and / or capillary openings on the opening plate, which is one

Also from the factors that complicate the production of the capsule and thus increase the financial costs necessary for its production.

The primary goal of these solutions is to prevent further leakage of liquid, resp. beverage after stopping the supply of hot pressurized water or steam, the flow of liquid, resp. the mixing of the ingredient and the liquid is practically in no way controlled and takes place spontaneously as it passes through the opening plate. The liquid with the ingredient flows over substantially the entire area of said plate into the labyrinth below said plate. For this reason, the path of the liquid with the ingredient through the labyrinth towards the outlet of the capsule is not always the longest, which is essential from the point of view of perfect mixing and dissolving the ingredient in the liquid and also capturing as much of any solid residues in the resulting liquid or drinks. This has a significant effect on the quality, resp. taste and appearance of the prepared drink.

The task of the present utility model is to create such a capsule construction where the liquid with the ingredient will flow perfectly, i.e. as long as possible, through the labyrinth or cascades on which the beverage is perfectly mixed and the deposits are trapped during the preparation of the beverage. This gives a delicious drink.

The essence of the technical solution

The above task is fulfilled and the shortcomings of the existing technical solutions (existence of the valve means, existence of through or through capillary openings located on the entire surface of the opening disk) are eliminated by the capsule according to this technical solution.

The ingredient capsule for preparing a beverage according to this technical solution comprises an ingredient storage space which is bounded by a capsule wall, one sealing foil firmly connected to the capsule top and a second sealing foil connected to the capsule wall for mounting in front of the capsule bottom, a disc stored in a conical housing in the shoulder in front of the capsule bottom, where a labyrinth and a guide protrusion corresponding to the outlet opening at the bottom of the capsule are formed on the underside of the disc and channels connecting the space above and below the disc are formed on the surface of the conical housing, the labyrinth formed of at least one concentric lamella on the disc which does not touch the bottom of the capsule and at least one concentric lamella integrated with the bottom of the capsule which does not touch the disc, the essence of which is that the disc is provided with a collecting well on the upper side; discharge channels leading to the edge of the disc, the channels being covered by a closure a sealing foil connected to the wall of the capsule for mounting in front of the bottom of the capsule and the sealing foil is weakened above the collecting well.

Preferably, the disk is provided on the upper side at the edge with at least one circumferential wall, on the upper side of which small flow grooves are formed, the grooves being covered by a sealing foil connected to the capsule wall for seating in front of the capsule bottom.

Examples of embodiments

Said exemplary embodiments describe the capsule 1 according to FIG. 1 to FIG. 3 and the disc 2 for the capsule 1 according to FIG. 4 to FIG. 9.

Capsule 1 and disc 2 for capsule 1 for a beverage preparation ingredient, wherein the capsule 1 has a conical shape and tapers downwards from the upper rim 3. Ingredient resp. The ingredients are located in the storage space 4 of the capsule L. This storage space 4 is delimited at the top by a sealing foil firmly connected to the upper rim 3 and from below by a sealing foil abutting the disc 2. The sealing foils are not shown in the figures, but are known from the prior art. The disk 2 is mounted with its conical surface 6 on its circumference in a conical bearing 7 formed in a shoulder 8 in the lower part of the capsule 1. The conical surface 6 is in close contact with the capsule 1.

In the shoulder 8, capillary channels 15 connecting the storage space 4 and the space under the disc 2 are formed on the surface of the conical bearing 7. The conical surface 6 of the disc 2 can be welded or glued around the circumference in the conical bearing 7.

Under the shoulder 8 on the inner surface of the capsule χ resp. two concentric lamellae 10 forming one part of the labyrinth are formed on the bottom 9 of the capsule 1 in this exemplary embodiment. The bottom 9 of the capsule 1 contains an outlet 11.

The disc 2 is provided on the upper side in the middle with a collecting well 5, from which the discharge channels 12 are led through a smooth passage and further towards the edge of the disc. The discharge channels 12 are covered with a sealing foil connected to the capsule wall on the shoulder 8 in front of the bottom 9 of the capsule 1. This sealing foil is weakened above the collecting well 5. The weakening of the sealing foil at a point above the collecting well 5 can be effected, for example, by partial cutting of the sealing foil. Said embodiment of the disc is specifically shown in FIG. 7 to 9.

In a preferred embodiment of the disc 2, which is shown in FIG. 4 to 6, the disk 2 is provided on the upper side at the edge with at least one circumferential wall

16, on the upper side of which small flow grooves 17 are formed. The flow grooves 17 are also covered by a sealing foil connected to the capsule wall on the shoulder 8 in front of the capsule bottom 9. The circumferential walls 16 with small flow grooves 17 also serve as labyrinths, i. ensure good mixing of the beverage and on the one hand support the closing function, i. after the beverage has drained and the pressure in the capsule has ceased, it is difficult, without the presence of pressure, to cause further spontaneous, undesired, outflow of the beverage from the capsule 1 through the outlet 11. If these flow grooves 17 are in the dimensions where the capillary effect occurs, they can also provide closing the capsule before the liquid overflows after the pressure has ended.

Furthermore, the opening disk 2, on the underside, is provided with a central protrusion 13 corresponding to the outlet 11 and two concentric lamellae 14 forming the second part of the labyrinth, so that after inserting the disk 2 into the capsule! these fit between the concentric lamellae 10, thus creating a complete labyrinth. At least one lamella 10 on the bottom 9 of the capsule 1 and at least one lamella 14 on the opening disc 2 are required to form the labyrinth.

Capsule 1 according to this technical solution works as follows. Hot pressurized water is introduced into the storage space 4 by known means, whereby it is mixed with the ingredient. Under the action of the liquid pressure, the lower sealing foil at the point of weakening above the collecting well 5 ruptures. The liquid flows into the collecting well 5 and from there it is discharged through the discharge channels 12 to the edge of the disc 2, where it flows through the capillary channels 15 under the disc 2 where it flows through practically the longest path through the labyrinth formed by lamellae 10 and 14 to the outlet opening IL.

Using a preferred embodiment of the disc 2, according to FIG. 4 to FIG. 6, the working principle is the same as described in the previous paragraph. In this case, however, the liquid additionally passes through the flow grooves 17 on the circumferential walls 16 on the peripheral part of the disk 2 before flowing through the capillary channels 15.

In the above arrangement, the liquid, resp. the beverage from the storage space 4 flows through the longest possible path through the labyrinth formed practically by the circumferential walls 16 and further by the lamellae 10 and 14. Such an arrangement creates cascades on which the beverage is maximally mixed and deposits are trapped, so that a homogeneous and high-quality beverage is obtained. In this case, the flow grooves 17 contribute significantly to the retention of the liquid in the capsule 1 after the end of the pressure application, i. after completion of the preparation of the beverage, when further outflow of liquid from the capsule 1 is undesirable, and is primarily provided by capillary channels 15.
