Definitions

  • This invention relates to apparatus for filling bottles or like containers with liquid.
  • the invention is particularly adapted for filling milk bottles but is not necessarily limited to this particular application of the invention.
  • apparatus for filling bottles or like containers with liquid comprises means for raising the liquid by suction from a tank or like storage space into an annular space, surrounding the neck of the bottle to be filled, whereby the level of liquid in the annular space is raised above the top of the bottle neck, whence the liquid is allowed to flow by gravity from the annular space into the bottle in an annular stream, the hollow centre of which provides a passageway for air in the bottle to flow out therefrom as the bottle is filled with liquid.
  • the annular space may be formed by the wall of a bell or the like dipping into a tank surrounding the bottle neck, and a cylindrical wall of the tank surrounding an outlet in which the neck of the bottle is positioned.
  • the bell or the like is adapted to be connected with a vacuum line for providing the necessary suction to raise the liquid from the tank upwardly within the annular space.
  • the apparatus comprises a tank for holding the liquid, means within the tank, which means provides an annular space surrounding the outlet from the tank around which outlet the neck of the bottle to be filled is adapted to be positioned, and means for raisin the liquid by suction from the tank into the annular space to such a level that the liquid can flow by gravity into the bottle in an annular form.
  • plunger means may be provided which, on actuation, is caused to enter the neck of the bottle to a predetermined depth, thereby displacing liquid from the neck of the bottle and forcing it to return to the tank.
  • the invention is particularly adapted for milk bottle filling machines of the rotary type wherein the bottles are automatically secured to outlets of a tank of milk on the machine and are filled and automatically released as the machine rotates.
  • the apparatus comprises a tank I having a series 01' outlets 2 and an annular sleeve 3 above and in axial alignment with the outlet 2 into which the neck of a bottle 4 is inserted by known means, the neck of the bottle being forced into engagement with a sealing gasket positioned betweenthe sleeve 3 and outlet 2;
  • the sleeve 3 is provided with a depending spout 6 which is adapted to extend into the neck of the bottle to be filled.
  • the lower end of the sleeve is provided with ports 1 to allow of liquid flow from the tank to the spout.
  • a hell or domeshaped members is provided for each outlet 2, the open end of the bell fitting around the outlet and dipping into the liquid 9 in the tank to a point below the normal minimum level of liquid.
  • the cylindrical wall of the bell and the wall of the outlet inside the bell form an annular space H], the purpose of which will become apparent below.
  • the upper end of the hell 8 is connected with a vacuum line H through which air in the bell can be exhausted by any suitable means, for example a centrifugal fan (not shown) it being, of course, understood that the suction, whilst being sumcient to exhaust the air to cause liquid in the tank to enter the bell is not sufficient to cause such an upsurge of liquid in the bell as to seal the outlet from the tank.
  • a centrifugal fan not shown
  • the central hollow space in the annular stream provides a passageway for air in the bottle to flow out as the bottle fills with liquid, and accordingly it is not necessary to provide any separate pipe or like means for exhausting the air.
  • the outlet 2 is provided with a rounded ofi lip I2 and an outlet IS.
  • the plunger l extends out p of the bell terminating in an operating extension I9, which extension is adapted to be contacted by.
  • chine is' rotated as before and suction created in the pipe II. If there is no bottle at an outlet 2 the suction merely causes air to be drawn up through the outlet 2 without causing liquid to be raised from the tank 9. As soon as a bottle is in position against the sealing gasket 5 a pressure difierence is created between the bell 18 and tank I which causes liquid to be sucked up. into the, annular space In until liquid flows as before by. gravitydown the outlet 2 to fill the bottle; 'When' the bottle is filled with liquid and; starts. to. fill the outlet 2 the plunger is caused to move down to enter the outlet and neck oi the bottle f he dimensions .oi: the plunger aresuch-as.
  • the apparatus comprises few parts all of which can be easily and completely cleansed which is an important advantage in the case of apparatus for bottling milk. 7
  • Apparatus for filling bottles or like containers with liquid including a liquid storage tank, means within the tank for positioning the V neck of a bottle so as to project above the level of liquid in saidtank, means within the tank for effectively sealing'ofi' the surface of the liquid occupying an annular space about the neck,
  • Apparatus according toclaim 1 in hich the sealing off; means comprises bell-shaped means dipping into the'tank, and surrounding the bottle neck, and the positioning means comprises an upwardly projecting cylindrical outlet wall in'the' tank, open for the. reception of the bottle necktherein, and having the upper rim of the wall positioned above the. liquid level in the tank.
  • the pressure reducing means comprises a vacuum producing means, connected to the bell-shaped means.
  • Apparatus according to claim 1 in which there is positioned in the annular space a sleeve member having a depending spout adapted to enter the bottle, the sleeve being ported to allow of liquid flow from the tank through the annular space to the spout.
