    摘要: The neck of a container for free-flowing food products appears as a duct (1), composed of a tubular element (6) and a connecting portion (7) that combine to establish a flow passage (8) between the container and the surrounding environment; the connecting portion (7) is moulded in one piece with the tubular element (6) and presents a mating surface (11) sealable hermetically to an outlet portion (5) of the container. The mating surface (11) consists of low density polyethylene, whilst the duct (1) includes at least one material of strength superior to that of low density polyethylene.

    摘要: An ultrasound sealing device (15, 20, 21), wherein an activating device (2), for generating vibrations of a wavelength of a given value L, has a first surface (11) contacting a second surface (17; 22) of a sonotrode (3); the activating device (2) and the sonotrode (3) having, respectively, a first and a second nodal surface (4, 5) substantially parallel to each other; and the second surface (17; 22) being located at a distance from the second nodal surface (5) of more than zero and less than L/4.
