Definitions

  • the present invention relates to a liquid filling nozzle for filling liquid or flowable food or the like into containers in a specified quantity for each container, said liquid filling nozzle comprising a tubular nozzle main body a short elastic body disposed in a lower end opening of the nozzle main body and opposed to the edge portion of the lower end opening with an annular liquid passing clearance formed therebetween, a suspending member having the elastic body suspended therefrom and extending along the inner peripheral surface of the elastic body.
  • the filling nozzle be capable of sharply cutting the flow of the liquid to be handlet.
  • known filling nozzles of the kind set forth (US-A-2,761,607) are provided at the orifice portion with a damper.
  • the damper is opened and dosed- in order to fill every specified quantity of liquid: Fibrous materials are likely to adhere to the: damper to render the damper no longer operable accurately.
  • the opening and closing movement of the damper gives rise to a churning phenomenon, possibly solidifying the fresh cream.
  • the solidified portion if contained in the product, will reduce the quality of the product.
  • the damper will not operate properly, failing to cut the flow of liquid sharply.
  • the main object of the present invention is to provide a nozzle for filling a liquid of whatever type into containers quickly and smootly.
  • the invention provides a liquid filling nozzle of the kind set forth, characterized in that the suspending member defines an annular pressurized ftuid- chamber along with the elastic body, and means have been provided for supplying a pressurized fluid to the chamber to inflate the elastic body.
  • the elastic body is inflated or contracted to close or open the opening of the nozzle main body at its lower end.
  • The- nozzle which does not include any mechanically operable part such as a damper has no likelihood of causing churning. Accordingly the nozzle sharply cuts the flow of a liquid of whatever type to assure a quick and smooth filling operation.
  • a filling nozzle comprising a suspending member for suspending there co-operating elastic valve members mounted in a passage extending through said suspending member so that said suspending member and said valve members define clearances which can be pressurized for moving the valve members towards each other in order to close the passage through said suspending member.
  • said liquid has to move through an opening having a circular cross- section. If the liquid is moved with an acceptable filling speed it furiously strikes against the bottom of the container into which the liquid is filled. As a result, the liquid is stirred or it jumps up and down to evolve air bubbles with the result of producing an unfavorable phenomenon. To prevent this phenomenon, there is no other way than to slow down the flow of liquid.
  • the present invention does not bring forth the above mentioned phenomenon at all thanks to the annular shape of the liquid passing clearance.
  • a further problem of the structure according US-A-3,195,586 is a poor sealing ability.
  • the sealing surfaces of said valve members are inner surfaces at which the deformed elastic bodies contact with each other and where the body is constituted of three members, a certain member needs to contact with the other two members simultaneously at the center portion of the liquid passing opening. This necessity might produce a clearance there, so that no tightness can be assured.
  • the drawing is a view in vertical section showing a liquid filling nozzle of the present invention.
  • the nozzle of the invention comprises a tubular nozzle main body 1, a short tubular elastic body 3 disposed in a lower end opening of the nozzle main body 1 and opposed to the edge portion of the lower end opening with an annular liquid passing clearance 2 formed therebetween, a suspending member 5 having the elastic body 3 suspended therefrom and extending along the inner peripheral surface of the elastic body 3 to define an annular pressurized fluid chamber 4 along with the elastic body 3, and means for supplying a pressurized fluid to the chamber 4 to inflate the elastic body 3.
  • the nozzle main body 1 comprises an upper member 6, an intermediate member 7 and alower member 8, which are joined to one another in alignment.
  • the upper member 6 has a larger diameter than the other members 7 and 8.
  • the upper member 6 is formed on the outer periphery of its upper end with an outer flange 9, which is engaged by an inner flange of a nut 10.
  • the nozzle is removably attached to the main body of a filling machine (not shown) by fitting the flanged nut 10 to the machine main body.
  • An annular groove 11 is formed in the upper surface of the outer flange 9 and has an unillustrated 0-ring fitted therein.
  • the upper member 6 is internally threaded as at 12 at a portion thereof close to its upper end and has an inner flange 13 on the inner periphery of its lower end.
  • the intermediate member 7 has a double structure which comprises inner and outher tubes 14, 15 arranged concentrically with a space formed therebetween. whereby condensation of water vapor is prevented during filling operation.
  • the upper end of the inner tube 14 is fitted in the inner flange 13 intimately and fixedly.
  • the lower end of the tube 14 is fitted in the lower member 8 intimately and fixedly.
  • the outer tube 15 has an upper end secured to the lower end of the upper member 6 and a lower end fixedly joined to the upper end of the lower member 8.
  • a downwardly tapered inner surface 16 is formed at the lower end opening edge portion of the lower member 8 to define the liquid passing clearance 2.
  • the elastic body 3 is integrally molded of rubber for food use and is substantially L-shaped in cross section.
  • the upper portion of the elastic body 3, which is approximately 2/3 of the whole, is tapered upward, so that the elastic body 3 has an upwardly tapered outer surface 17 and is formed on its inner periphery with flanges 18, 19 at the upper and lower ends thereof, respectively.
  • the suspending member 5 comprises a short solid cylinder 20 intimately fitted in the upper member 6 of the main body 1, a pressurized fluid tube 21 fixed at its upper end to the central portion of the bottom of the solid cylinder 20, and a cone 22 fixed to the lower end of the fluid tube 21.
  • the solid cylinder 20 has an externally threaded upper portion 23, which is screwed in the internally threaded portion 12 of the upper member 6. Between the bottom surface of the solid cylinder 20 and the upper surface of the inner flange 13 of the upper member 6, there is a small clearance in which an 0-ring 24 is provided.
  • a plurality of bores 25 extending through the cylinder 20 are equidistantly arranged on a circumference having a given radius from the center of the cylinder.
  • the fluid tube 21 has an externally threaded lower end portion 26.
  • the cone 22 has a central hollow portion 27, from which a threaded bore 28 extends upward through the cone.
  • the externally threaded portion 26 of the fluid tube 21 is screwed in the threaded bore 28.
  • the conical surface 29 of the cone 22 is formed with annular grooves 30, 31 at its upper and lower ends, respectively.
  • the elastic body 3 is fitted over the cone 22 to cover the conical surface 29, and the flanges 18, 19 of the elastic body 3 are fixely fitted in the annular grooves 30, 31, respectively, whereby the annular pressurized fluid chamber 4 is formed between the elastic body 3 and the cone 22.
