Abstract: A container for pouring liquids, composed of a vessel having a longitudinal axis and a bottom, and a pouring lip made of a plastic material. The pouring lip has a central pouring part having a pouring end, and lateral parts, and the lip is composed of: an upper wall, a lower wall and a connecting surface that extends between the upper wall and the lower wall; the upper wall is inclined downwardly into the vessel when the longitudinal axis of the vessel has a vertical orientation; and, in the central pouring part, the connecting surface is free of any sharp edge and has an upper segment having a radius of curvature between 0.5 and 2 mm in a plane passing through the longitudinal axis.

Abstract: An extraction cell of the centrifugal type for a hot beverage preparation machine, including a grounds collection drum on which is mounted, in a sealed manner by a sealing structure, a cover provided with a liquid delivery orifice, and a filtration structure, wherein the filtration structure and the sealing structure are constituted by at least one deformable joint, or seal, interposed in a groove between the drum and cover, the joint having deformation properties, and being mounted to be compressed by an amount which is in a pre-established compression range with the aid of a compression controlling means, to insure that below a pre-established operating pressure existing in the cell, fluid tightness of the cell is maintained, and beyond that pressure, filtration of the grounds-liquid mixture occurs by deformation of the joint.
