Description

Technical field

The invention relates to a capsule for a beverage ingredient.

BACKGROUND OF THE INVENTION

At present, various types of capsules intended for the production of beverages in devices injecting hot pressurized water or steam into the inside of a capsule containing an ingredient for the preparation of a beverage are known both from practice and from patent literature. The beverage preparation ingredient in the described type of capsule is sealed with foils, usually aluminum. In front of the bottom of the capsule there is an opening plate with elements for perforating the bottom sealing foil. When the pressurized water or steam is introduced into the capsule, which is done by introducing the injection needle through the top sealing foil, the ingredient begins to mix with water, and the bottom sealing foil is also perforated by pressure on the opening plate. On the one hand, the opening plate is provided with opening means, which are usually spikes, and also contains openings for fluid flow, and in some cases also valve means, which are intended to prevent further leakage of the liquid, respectively. beverage after stopping the supply of pressurized water or steam. On the opposite side of the opening means, the opening plate is usually provided with a labyrinth usually formed by a set 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 discloses an opening plate capsule comprising valve means and perforating means.

WO2008 / 116818 describes a capsule with valve means on a plate as well as perforating means. In addition to these means, the plate also comprises capillary openings. In another European application EP08100448 a capsule is described wherein the valve means located on the plate cooperates with the capsule wall. Also, recess circles are provided from the bottom of the plate, i. Labyrinth. Similar solutions are also described in EP05104016 and WO2007 / 141202. The solutions described also include valve means and / or capillary openings on the opening plate, which is one

factors that complicate the production of the capsule, thereby increasing the financial costs necessary to produce the capsule.

The primary objective of the above solutions is to prevent further leakage of liquid, respectively. beverage after stopping the supply of hot pressurized water or steam; the mixing of the ingredient and the liquid is virtually uncontrolled and takes place spontaneously as it passes through the opening plate. The liquid with the ingredient will flow substantially over the entire area of said plate into the labyrinth below said plate. For this reason, the liquid pathway of the ingredient through the labyrinth towards the capsule outlet is not always the longest, which is essential in order to thoroughly mix and dissolve the ingredient in the liquid, and also to retain as much of any solid residue as possible in the resulting liquid. drinks. This has a significant impact on the quality or quality of the material. taste and appearance of prepared drink.

The object of the present utility model is to provide a capsule structure in which the liquid with the ingredient will flow perfectly over the labyrinth or cascade through the labyrinth or cascades where the beverage is prepared to mix the beverage and collect the deposits perfectly. This gives a delicious beverage.

The essence of the technical solution

The above task is accomplished and the drawbacks of existing technical solutions (the existence of valve means, the existence of through or through capillary openings throughout the opening disc surface) are eliminated by the capsule of the present invention.

The beverage ingredient capsule according to the present invention comprises an ingredient storage compartment which is bounded by the capsule wall, one closure film firmly attached to the top edge of the capsule and the other closure film attached to the capsule wall and seated on the perforating tips of the opening disc. in a shoulder in front of the capsule bottom where a labyrinth and a baffle are formed on the opening disc corresponding to the outlet opening at the bottom of the capsule, the essence of the solution is that the perforating spikes on the opening disc are aligned in rows from the center of the disc and

- the discharge disc has a conical surface on the circumference, which corresponds to a conical surface formed in the shoulder in front of the capsule bottom, where on this conical surface there are formed channels connecting the space above and below the opening disc, wherein the labyrinth between the capsule bottom and the opening disc is formed of at least one concentric lamella on the opening disc that does not touch the bottom of the capsule and at least one concentric lamella integrated with the bottom of the capsule that does not touch the opening disc.

In a preferred embodiment of the present invention, the drain grooves are flush with the channels on the conical surface in the shoulder before the bottom of the capsule. When the top closure film is pierced and the liquid is introduced into the storage space and the ingredient is mixed with the liquid and the bottom film is perforated by the perforating spikes on the opening disc, the liquid is led through the drain grooves to reach the channels on the cone surface.

The position of the channels on the conical surface of the capsule according to this solution allows the liquid or the liquid to be removed. the beverage, after perforating the backsheet, preferably by means of the drainage grooves, is fed to the perimeter of the disc so that the entire volume flows through virtually the entire length of the labyrinth to the outlet opening. Therefore, the opening disc does not contain flow openings through which the liquid or the liquid can be removed. the beverage would flow into the outlet or would flow only in a short way which would not fulfill the task of this technical solution. The opening disc is made without any through holes and is tightly seated in a conical fit in the capsule. The tight fit of the opening disc in the capsule means a watertight connection of the respective contact surfaces of the opening disc and the capsule. The tightness is ensured by the conical surfaces and the pressure exerted in the capsule during the preparation of the beverage. In a preferred embodiment, the opening disc may be mounted in a capsule or a capsule. a firm connection of the opening disc and the capsule at the contact points, e.g. welding or gluing, thus the required tightness of the joint is guaranteed.
