Definitions

  • ABSTRACT A filling system for carbonated beverages includes a ⁇ 30] Foreign Application Priority Data Sept. 12, 1970 Germany............................
  • the present invention relates generally to container filling systems, and more particularly to systems which fill containers with liquids, particularly with carbonated beverages.
  • filling apparatus in which the portion of the filling channel located above the container inlet is of slightly conical configuration, and the liquid is directed through this portion by a deflector which is located approximately in the upper region of the container inlet on the vent tube of the filling unit which extends into the container during the filling operation.
  • the deflector itself guides the liquid against the inner surface bounding the inlet of the container, from where the liquid moves without excessive turbulence against the bottom wall of the container or against the surface of the liquid already accommodated in the container.
  • This construction is particularly known in so-called counter-pressure filling units which do not utilize a filling tube, and located between the filling head and the inlet opening of the container there is provided in accordance with the prior art an axially movable center.- ing member or hell the sealing of which contacts both the container about the inlet opening thereof and the filling head, in order to provide a closed space between the filling head and the container through which the liquid can pass.
  • the annular space defined by the filling head immediately adjacent the connection with the sealing element is slightly offset in inward direction with respect to the annular space defined by the sealing element itself, meaning that there is a variation in the cross-section of the passage through which the liquid flows. This results in every case in a disturbance of the liquid flow and a concomitant turbulence in the liquid. Also, in the known conical configurations of the liquid channel, a reduction of the flow through cross section exists which has been found to substantially reduce the filling speed of such apparatus.
  • a filling system for filling liquids into a container which briefly stated comprises a container having an inlet opening, a filling head having a circular outlet opening adapted to be placed into registry with the inlet opening, and a centering element on the filling head for centering the outlet opening with respect to the inlet opening.
  • a sealing element sealingly interposed between the centering element and the inlet opening of the container, and in accordance with the invention this sealing element has an inner circumferential surface so dimensioned as to define with the inlet and outlet openings a cylindrical liquid-flow passage of constant cross section.
  • the liquid flow passage thus defined is smooth or almost completely smooth, being without any appreciable changes in its cross-section, so that the turbulence induced in the flowing liquid by such crosssectional changes which exist in the prior artis avoided and the liquid can flow quietly and without formation of turbulence.
  • the diameter of the inlet opening and of the passage in the sealing element prior to scaling interposition of the latter between the centering element and the container correspond at least approximately to the diameter of the inlet opening of the container.
  • the filling head in the system according to the present invention utilizes a vent tube through which air or gas is vented from the interior of the container as the latter is being filled with liquid.
  • a vent tube through which air or gas is vented from the interior of the container as the latter is being filled with liquid.
  • Such vent tube extends coaxially through the inlet and outlet openings and carries in the region of the inlet opening of the container a deflector which deflects the incoming liquid against the wall of the container bounding the inlet opening.
  • the cross section of the annular space defined between the cylindrical liquid filled passage and the vent tube extending therethrough in a radial plane of the passage is larger than the cross-section defined between the largest diameter of the annular deflector and the circumferential wall of the container again in a radial plane of the flow passage and, of course, of the vent tube.
  • the sealing element is advantageously provided with a sealing lip at the side which is to contact the container and which in the condition in which it is pressed against the container about the inlet opening thereof has a contour which corresponds at least substantially to the contour of the container wall portion surrounding the inlet opening.
  • FIGURE illustrates in fragmentary somewhat diagrammatic form an exemplary embodiment of the invention.
  • the filling system illustrated therein comprises a filling head having a valve housing 1 formed with a flow passage 2 which is to communicate with an inlet opening 24 of a container 3 to be filled, here illustrated as a bottle.
  • a valve member 4 is arranged coaxially with the passage 2 and provided with a sealing ring 5, and the valve member 4 can be raised or lowered to open or close the valve at the beginning and the end of the filling operation, respectively.
  • a vent tube 6 is secured centrally on the valve member 4, at the lower end thereof, and it carries on its outer circumference a deflector 7 of annular configuration as illustrated. In operation the deflector 7 will be located in the interior of the container 3 as shown.
  • a ring 8 is arranged coaxially with the passage 2, and a downwardly directed major surface 9 of the ring 8 delimits one axial side of an annular space 10, the other axial side of which is determined by the annular surface 11 of the valve housing 1.
  • a further annular gap or space 12 is delimited by an inner circumferential surface 13 of the ring 8 and the valve member 4 itself.
  • a centering member or bell 14 carries a sealing element l and is mounted shiftably intermediate the valve housing 1 and the container 3.
  • the passage 2 has a conically convergent portion 16 and, downwardly thereof, is of cylindrical cross-section.
  • the sealing element 15 which is of annular configuration
  • the inner circumferential surface of the sealing element defines with the inlet opening 24 of the container 3 and the cylindrical outlet opening of the passage 2 a cylindrical liquid-flow passage 17 of constant cross-section, that is of a cross-section which is not changed where the central passage of the sealing element 15 merges with the outlet opening of the passage 2 or with the inlet opening 24 of the container 3, respectively.
  • the drawing also shows that the cross-sectional surface area 18 in the radial plane of an annular space 19 defined between the outer circumferential surface of the vent tube 6 and the inner circumferential surface bounding the passage 2 is greater than the crosssectional surface area 20 in the radial plane of the annular gap defined between an inner circumferential surface 21 of the wall of the container 3 and the largest diameter of the deflector 7.
  • the ratio of these crosssectional areas of the gaps l8 and 20 is advantageously on the order of between 1.111 and 1.4:1. It has been found that particularly good flow-through conditions are obtained if a ratio of 1.26:1 is chosen.
  • the sealing element 15 which may be of a suitable elastomeric material well known to those skilled in the art, is supported by the centering bell 15 as illustrated and provided with a sealing lip 22 whose contour when the lip is pressed against an end face 23 or the wall portion 26 bounding the inlet opening 24 of the container 3- corresponds at least substantially to the configuration of the end face 23 at the container neck 25.
  • the flow through passage 17 which is thus created is continuous and bounded by what amounts to a smooth internal surface which is not interrupted by recesses or projections in the region of the transition between the sealing element 15 and the outlet of the passage 2 on the one hand, or the inlet 24 of the container 3 on the other hand. This means that no turbulence is induced in the liquid flowing through this passage 17 and the disadvantageous conditions obtaining with respect to the prior art are avoided.
  • the container 3 itself should be considered a part of the novel filling system, because the passage 17 is defined by the sealing element 15 in conjunction not only with the outlet of the passage 2 but also with the inlet 24 of the container 3, because the smooth turbulence-free transition between the element 15 and the inlet 24 of the container 3 is as important as the similar transition between the element 15 and the outlet of the passage 2.
  • a filling system for filling liquid under pressure into a container comprising a container having a neck portion provided with a cylindrical inlet opening of a predetermined cross-sectional area and having an end face surrounding said inlet opening and having apredetermined surface area; a filling head having a cylindrical outlet opening of said predetermined crosssectional area and adapted to be placed in registry with said inlet opening; an annular sealing element having a cylindrical central passage of said predetermined crosssectional area and an annular surface portion of said predetermined surface area and sealingly interposed between said inlet opening and said outlet opening; and a centering member on said filling head engaging said neck portion and said sealing element for centering said outlet opening and said passage with reference to said inlet opening and for centering said annular surface portion with reference to said end face, to thereby obtain a cylindrical transition-less liquid-flow path of constant cross-sectional area.
  • a filling system for filling liquid under pressure into a container comprising a container having an inlet opening and an inner wall surface merging with said inlet opening; a filling head having a circular outlet opening adapted to be placed into registry with said inlet opening; a centering element on said filling head for centering said outlet opening with respect to said inlet opening; an annular sealing element sealingly interposed between said centering element and said inlet opening of said container, said sealing element having a central passage bounded by an inner circumferential surface dimensioned to define with said inlet and outlet openings a cylindrical liquid-flow passage of constant cross-section; a vent tube carried by said filling head and extending coaxially through said liquid-flow passage so as to define therewith a first annular gap, said vent tube comprising a portion extending into said container downstream of said inlet opening; and an annular deflector for deflecting the liquid entering through said inlet opening radially outwardly of said vent tube toward said inner wall surface, said deflector being coaxially supported on said
