FIELD: personal use articles.SUBSTANCE: invention relates to preparation of beverages with the help of a device adapted for receipt of a disposable capsule containing the beverage substance. The invention objective consists in exclusion of water leakage from the unit through the clamp spot. The device contains a boiling unit intended to accommodate the capsule after relative closure of the first and the second fastening elements forming the cavity to enclose the capsule and receiving the capsule on a flange-shaped rim to provide for liquid tight sealing. The first and the second fastening elements contain an essentially ring-shaped holding-down section for application of a sealing force to the capsule flange-shaped rim; the first and the second fastening elements are designed so that to enable their mutual closure at the clamp spot to ensure infiltration of liquid injected into the cavity in the absence of the capsule. Additionally, the first and the second fastening elements contain (within their ring-shaped holding-down sections) flow direction means having at least one passage to ensure controllable infiltration of liquid in the radial direction only within a limited arc section after closure of the first and the second fastening elements at the clamp spot.EFFECT: exclusion of water leakage from the unit through the clamp spot.22 cl, 8 dwg |
