Split container for making beverage by granular material with the help of water

Abstract

A split container is proposed for the preparation of a beverage, preferably espresso coffee, using a granular, water-extractable substance (KP). Here, between the container base (7) and the substance (KP) and between the container lid (4) and the substance (KP), a dispensing device provided with a large number of holes (8, 14) for dispensing water or beverages is arranged. elements or collecting elements (2, 3). The collecting element (2) and the distributing element (3) are provided with at least one groove (10, 15) pointing to the inside of the container, while the piercing member (20, 21) can penetrate the container bottom (7) or the container cover (4 ) then extend in the grooves (10, 15).

Description

Technical field [0001] The present invention relates to a split container for making beverages with granular substances extractable by water as described in the preamble of claim 1. Background technique [0002] Many variants of this type of split container are known, among which a split container for making espresso for holding ground coffee is particularly known. The fundamental advantage of this split container is that it is airtight and keeps the contained coffee powder fresh for a long time. In order to infuse the coffee powder contained in the split container, semi-automatic espresso coffee machines are now mainly used, in which the container is installed downwardly in a container seat with a closure lid. The container holder is then manually fixed on the coffee machine, wherein the coffee machine has a boiling pin (Bruehdorn) on the fixed part of the split container holder, which is provided with a radial outlet hole for guiding boiling water through, and is When the conta...

AI Technical Summary

Problems solved by technology

As the contamination of the boiling pin increases, the quality of the brewed coffee beverage also decreases

Another problem with such a boiling pin from a hydraulic point of view is that there is a dead volume (Totvoluminas) inside the container, so that part of the ground coffee cannot be extracted by boiling water, or only an insufficient amount of ground coffee

[0007] A fundamental disadvantage of this known split pack is that the coffee machine needs to be worked very hard so that the ground coffee contained in the split pack is passed through as evenly as possible by the boiling water and fully extracted

In addition, there is the danger that the separate packaging, which opens only after the extraction process starts under the effect of the pressure of the extraction liquid, will not open in all desired positions—that is, Perforated - so that the ground coffee is only under-extracted

Another disadvantage can be seen here: the perforation part is larger than desired, which is not ideal for boiling water flowing through it, because there is only a small flow resistance to hinder the boiling water; besides this, there is the danger of: Ground coffee can escape from the split pack through an opening that is too large, which can contaminate the machine
