Abstract: The dispenser device for liquid substances has a chamber for accommodating a liquid substance, at least one first passage arranged in an upper portion of the chamber and adapted to allow the inflow of the liquid substance into the chamber, and a dispenser suitable for feeding the liquid substance into the chamber through the first passage. A second passage is provided for the outflow of the liquid substance from a lower portion of the chamber, a valve adjusts the flow of the liquid substance through the second passage, and a flow deflector element is arranged within the chamber and is interposed in a fixed position between the first passage and the second passage. The deflector element has a substantially torroidal shape, and an intermediate portion thereof flanks, at a substantially constant distance, the inner surface of the chamber.

Abstract: The apparatus for conveying containers in a filling machine comprises a rotary conveyor which has a plurality of mutually angularly equidistant sucker holder elements, each of which is adapted to accommodate a related container. Each sucker holder element is mounted so as to be radially slidable on the rotary conveyor, and adjustment elements are provided for modifying, in a radial direction with respect to the rotary conveyor, the position of the holder elements so as to adapt the apparatus for handling containers of various sizes without requiring the replacement of mechanical parts.

Abstract: The apparatus for feeding closures provided with a tube to an operating unit, has a rotatable disk-like body, having a substantially vertical axis and a fixed or movable wall which delimits the body peripherally. The disk-like body has a circular supporting wall which is permeable to air at an outer annular portion, and is provided with a peripheral annular track adapted to accommodate closures arranged with their tubes directed upward. A pump is provided and arranged below the supporting wall to direct a jet of air with a substantially vertical direction toward a portion of the lower surface of the supporting wall so as to lift the closures from the circular supporting wall and push them toward the peripheral annular track from which closures exit through a passage defined in the wall which delimits the disk-like body.

Abstract: Apparatus for correctly positioning dispensers to be applied to containers, wherein containers and dispensers are fed in succession to an aligning conveyor which comprises a plurality of housings adapted to receive respective dispensers and to support them rotatably about their respective axes. A fixed abutment element is arranged adjacent to the aligning conveyor and is adapted to interfere with a portion of the peripheral surface of the dispensers to cause a rotation of the dispensers about their respective axes during their movement on the aligning conveyor. A photocell is provided for sensing the position assumed by a given portion of each rotating dispenser, and suckers are also provided and controlled by the photocell in order to lock each dispenser within the related housing when a given position is reached.

Abstract: Apparatus for applying closures to containers, comprising a first rotating conveyor adapted to move containers to be closed to a second rotating conveyor, and a third rotating conveyor adapted to remove the closed containers from the second conveyor. The second conveyor comprises a rotating supporting element adapted to receive and transfer containers in succession, and grip elements which overlie the supporting element and are adapted to receive in succession closures which are downwardly provided with a tube for extracting the liquid contained in the containers and to screw the closures on the containers after the tubes have entered the containers. The apparatus furthermore comprises grip elements which are adapted to grip the upper portion of the tubes before they are inserted in the containers and to slide toward the lower end of the tubes so as to straighten the tubes and allow them to correctly enter the containers.
