  • Patent number: 5467527
    Abstract: A capping unit wherein a number of capping heads, movable with a supporting carrousel conveyor about a first axis, are each rotated about a respective second axis by a respective first shaft movable axially on the carrousel conveyor, for moving the respective head to and from a respective container movable with the carrousel conveyor and coaxial with the second axis. Each head provides for closing the respective container with a cap presenting an internally threaded ring nut mounted for rotation on a pump-operated nozzle, and presents a first and second gripping device for respectively gripping the nozzle and the ring nut and controlled by a second shaft movable axially in relation to the first shaft. The first gripping device is angularly fixed in relation to the carrousel conveyor, whereas the second gripping device rotates with the capping head about the second axis.

  • Patent number: 5228604
    Abstract: The dosage dispensing device associable with filling machines is provided with at least one lower nozzle which includes a main body, which has a vertical axis, which is hollow and which has an internal diameter which reduces gradually at least proximate to its lower end down to a discharge outlet, and by a stem, which is arranged so as to be coaxially movable inside the main body. The stem defines, at its lower end, a shutter for the discharge outlet, and is provided with longitudinal fins for guiding the stem inside the main body; the shutter is constituted by a solid of revolution which is coaxial to the stem and which has a cross-section which decreases from a median region thereof down to a lower pointed end thereof, and the inner surface of the main body which is proximate to the discharge outlet has a shape which can be sealingly coupled to a lower portion of the shutter.

  • Patent number: 5157898
    Abstract: The apparatus for applying closures to containers having a neck which is inclined with respect to a vertical axis of the containers comprises: a first conveyer and a second conveyer for transferring the containers in succession. A closure application conveyor receives containers from the first conveyor and transfers them to the second conveyer. The closure application conveyor is provided with a plurality of clamps for gripping the containers arriving from the first conveyer, and is provided with a plurality of closure application heads whose respective lines of action are inclined with respect to a vertical axis. Actuation devices are provided which rotate the clamps in both directions about the vertical axes of the related containers in order to align the axes of the necks with the lines of action of the respective closure application heads.
