Field of technology

The technical solution relates to a capsule for an ingredient for the preparation of beverages.

BACKGROUND OF THE INVENTION

There are currently several types of capsules known in the art or from the patent literature that have been developed for preparing beverages in devices that inject hot water under pressure or steam into the capsule containing the beverage preparation ingredient. The ingredient for preparing the beverage is enclosed in the described type of capsules by means of foils, usually aluminum foils. There is an opening plate with elements for perforating the lower closing foil in the front part of the bottom of the capsule. After the pressurized water or steam is injected into the capsule through the needle through the upper closure foil, the ingredient is mixed with the water and the lower closure foil is perforated by the pressure on the opening plate. The opening plate is equipped with opening tools, usually blades, and there are also holes for draining liquid, in some cases even valve tools, which prevent further leakage of liquid or beverage after the pressure water inlet is stopped. or steam. The opening plate is usually equipped with a labyrinth comprising a system of internal partition walls on the other side of the opening tools, which labyrinth serves to mix the ingredient with the water before the finished beverage flows out of the capsule outlet.

There is a capsule with an opening plate containing a valve tool and perforating tools described in European patent application EP 06011671. The application WO 2008/116818 describes a capsule with a valve tool on the plate as well as with perforating tools. In addition to these tools, there are capillary holes in the plate. European patent application EP 08100448 includes a capsule where the valve instrument is placed on the plate and interacts with the wall of the capsule. In addition, on the underside of the plate there are circles with slots, the so-called labyrinth. Similar solutions can be found in patent applications EP 05104016 and WO 2007/141202. The described solutions also contain a valve tool and / or capillary openings on the opening plate, which is one of the factors that complicate the production of the capsule, leading to higher production costs.

The main purpose of the presented solutions is to prevent further leakage of the liquid or beverage after the supply of hot water under pressure or steam has been stopped, taking into account that the flow of the liquid or the mixing of the ingredient with the liquid is not controlled in any way and occurs spontaneously as the flow passes through the opening plate. The liquid with the ingredient practically flows through the entire area of the plate in the labyrinth under the plate. Therefore, the path of the liquid with the ingredient through the labyrinth towards the capsule outlet is not always the longest, which is essential in terms of perfect mixing and dissolving of the ingredient in the liquid, as well as the ability to capture multiple solids. residues in the finished liquid or beverage. This significantly affects the quality or taste, as well as the appearance of the drink.

The task of the presented utility model is to develop a capsule design in which the liquid with the ingredient will flow flawlessly, ie. will run as long as possible through the maze or cascades, in which the drink mixes perfectly and the remains are captured. This is the way to prepare a delicious drink.

Technical essence of the utility model

The above-mentioned task is fulfilled and the shortcomings of the existing technical solutions (presence of a valve tool, presence of a passage or of passage capillary openings on the whole area of the opening disk) are removed from the capsule in accordance with this technical solution.

According to this technical solution, the beverage ingredient capsule consists of a storage space with the ingredient bounded by the capsule wall, a sealing foil inextricably linked to the upper edge of the capsule and a second sealing foil connected to the capsule wall. on the body, before the bottom of the capsule, the disc in

2633 UI the conical support in the body against the bottom of the capsule, where on the underside of the disk there is a labyrinth and a guide protrusion corresponding to the outlet in the bottom of the capsule, and on the surface of the conical support there are channels connecting the space above and below the disk. Whereas the labyrinth between the bottom of the capsule and the disk is formed by at least one concentric lamella on the disk 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 opening disk , which consists in the fact that the disk is equipped with a storage opening on the upper side, in the middle, from where the exhaust channels lead to the edge of the disk, whereas the channels are covered with a sealing foil connected to the capsule wall on the body, before the bottom of the capsule, and that the closure film is reduced above the storage opening.

It is very effective if the disk is provided with at least one outer wall on the upper side in the part of the edge where small channels for the flow are formed in its upper side, given that the channels are covered by the sealing foil connected to the bottom of the the capsule on the body before the bottom of the capsule.

Exemplary implementations of the utility model

Exemplary embodiments describe the capsule 1 in accordance with Figure 1 to Figure 3 and the disk 2 for the capsule 1 in accordance with Figure 4 to Figure 9.

The capsule 1 and the capsule disc 2 are for a beverage ingredient, wherein the capsule 1 is conical and tapers from the top edge 3 downwards. The ingredient or ingredients are located in the storage space 4 of the capsule 1. This storage space 4 is bounded at the top by a closure film inextricably linked to the upper edge 3 and by a closure film mounted at the bottom of disk 2. The closure films are not shown on figures, however, their construction is consistent with the current state of the art. The disk 2 is placed on its perimeter by its conical surface 6 in the conical support 7 formed in the body 8 in the lower part of the capsule 1. The conical surface 6 is in direct contact with the capsule 1.

In the body 8 there are capillary channels 15 on the surface of the conical support 7, which connect the storage space 4 and the space under the disk 2. The conical surface 6 of the disk 2 can be welded or glued along the edge in the conical support 7.

Below the body 8, on the inner surface of the capsule 1, or on the bottom 9 of the capsule 1, there are two concentric lamellae 10, forming a part of the labyrinth formed in the exemplary embodiment. At the bottom 9 of the capsule 1 is the outlet 11.

The disk 2 is provided with a storage opening 5 on the upper side, in the middle, from which the exhaust channels 12 lead continuously and towards the edge of the disk. The outlet channels 12 are covered with a sealing foil which is connected to the bottom of the capsule on the body 8 before the bottom 9 of the capsule 1. This sealing foil is

2633 UI reduced above the storage opening 5. The reduction of the closure film above the storage opening 5 can be achieved, for example, by partially cutting the closure film. Said embodiment of the disk is shown in Figures 7 to 9.

In the effective embodiment of the disk 2, which is shown in Figures 4 to 6, the disk 2 is provided with at least one outer wall 16 on the upper side in the part of the edge which contains small channels for the flow 17 on the upper side. The flow channels 17 are also covered with a sealing foil connected to the capsule wall on the body 8 before the bottom 9 of the capsule 1. These outer walls 16 with small flow channels 17 perform the function of a labyrinth, i. a solution for good mixing of the drink, and they also support the closing function, ie. once the beverage has expired and the action of the pressure in the capsule 1 has ceased, they make it more difficult for the spontaneous, undesired leakage of the beverage from the capsule 1 through the outlet 11 into the absence of pressure. If these flow channels 17 are sized to be a capillary phenomenon, they can provide closure of the capsule before the overflow of the liquid after the action of the pressure has ceased.

In addition, there is an opening disk 2, in the lower part equipped with a central protrusion 13 corresponding to the outlet 11 and two concentric lamellae 14 forming the second part of the labyrinth, so that they engage between the concentric lamella 10 after inserting disk 2 in capsule 1, which creates the full maze. To create a maze, at least one lamella 10 at the bottom 9 of the capsule 1 and at least one lamella 14 on the opening disk 2 are required.

Capsule 1, in accordance with this technical solution, works as follows. The pressurized hot water is brought to the storage space 4 in the known manner and it is mixed with the ingredient. Due to the pressure of the liquid, the lower sealing film is torn at the reduced point above the storage hole 5. The liquid flows into the storage hole 5 and is brought to the edge of the disk 2 through the exhaust channels 12, where it flows under the disk 2 through the capillary channels 15. in essence, it travels the longest path through the labyrinth formed by lamellae 10 and 14 to the outlet 11.

In the effective implementation of disk 2, in accordance with Figure 4 to Figure 6, the principle of operation is the same as described in the previous paragraph. However, in this case, the liquid also flows through the flow channels 17 on the outer walls 16 in the part of the edge of the disk 2 before flowing through the capillary channels 15.

In this embodiment, the liquid or beverage will travel as long as possible from the storage space 4 through the labyrinth formed mainly by the outer walls 16 and the lamellae 10 and 14. Such a construction creates cascades leading to maximum mixing of the beverage and precipitates. , so that a homogeneous drink of high quality is obtained. The flow channels 17 contribute significantly to the retention of the liquid in the capsule 1 after the pressure has ceased to act, i. after the preparation of the beverage has been completed, when further leakage of liquid from capsule 1 is undesirable and is mainly provided by the capillary channels 15.
