Filling element for counter pressure bottle fillers

The invention relates to a filling element for counter-pressure bottle fillers with controlled liquid and gas valves as well as a coaxially arranged underneath, penetrated by the central air tube The mouthpiece of the liquid from the rubber of the centering bell is designed to be grasped and has a relief valve with an associated relief channel.

It is already known that such semi-automatic filling valves which are especially used for bottling carbonated beverages, in addition to the central air tube, which is used to tension the bottles and discharges the displaced return gas during filling, with its own relief valve Provide relief channel. After the filling process is completed, the inside of the Bottle brought into contact with the outside atmosphere by opening the relief valve and by blowing off the inside of the bottle The prevailing pressure is already reduced to ambient pressure before the bottle is removed from the filling element. Through the relief valve and a possibly provided throttle point, the relief process can be delayed in any way. A sudden » Push that the contents of the bottle - mostly carbonated drinks -

could cause concern and over-foaming, can thereby

be avoided.

** "- It is already known the Kao leading to the relief valve

° nal to connect to the interior of the liquid mouthpiece.

It is inevitable that when the pressure is reduced, which is associated with a considerable flow of gas through the relief channel,

in the liquid mouthpiece, in the relief channel or at the air lock Liquid still present is entrained and through each relief channel and the relief valve as spray liquid got to the outside. Spray liquid is generally undesirable; it means loss of filling material and moisturizes and wets the filler, the bottles to be filled and often has to be collected separately in containers.

The object of the invention is to avoid these disadvantages and, in the case of the specified filling elements, not only to quickly and smoothly relieve the inside of the bottle, but also to achieve an almost spray-free relief. In addition, the invention achieves that the spray channel cannot fill with liquid during the filling process and any moisture present in the spray channel automatically gets out of the spray channel and into the bottle when the bottle is removed. To solve this problem, it is proposed according to the invention that the relief channel begins at the lower end and outside the liquid mouthpiece and is initially led steeply upwards. The opening ji of the relief channel is therefore not inside ψ of the bottle mouthpiece, but outside it and the entry of the gas to be discharged takes place steeply from below. Adhesive liquid located in the interior of the liquid mouthpiece and in the air lock of the liquid mouthpiece cannot easily be dragged into this opening. Rather, it flows downwards and ends up in the bottle. A filling of the relief channel during the filling process is excluded.

According to the invention it is further proposed that the relief channel is formed on the outside of the liquid mouthpiece as an outwardly open groove.

According to the invention it is also proposed that the pressure rubber of the bottle centering bell is designed as a tubular intermediate piece between the end of the liquid mouthpiece and the mouth of the bottle. The liquid mouthpiece can be shortened by the tubular design of the pressure rubber. This in turn allows a very short relief channel to be provided in which little moisture can accumulate. In addition, according to the invention, the front, largest part of the liquid channel is designed like a channel and thus runs on the outside of the liquid mouthpiece as a groove-shaped channel, aj.r is closed off and sealed off from the outside by the sealing rubber when the centering bell is pressed on. If the bell reaches the bottom, the relief channel is automatically opened to the outside and any moisture that may be present does not remain in the relief channel, but can flow downwards and reach the inside of the bottle via the tubular intermediate piece of the centering bell.

According to the invention it is further proposed that a gas lock in the form of a sieve or the like is provided above the mouthpiece in a known manner. The design of the relief channel according to the invention is particularly important when a gas barrier in the form of a sieve or the like is provided, because a lot of moisture is released from this air barrier during the relief process and, according to the invention, not via the relief channel and the relief valve to the outside as spray liquid can be blown off.

The invention is shown schematically and by way of example in the drawing.

draws. The liquid mouthpiece 4 is disproportionately short, but the tubular sealing rubber Ja of the centering bell 7 transfers the liquid from the end of the liquid mouthpiece 4 to the mouth of the bottle 6. On the outside of the liquid mouthpiece 4, the relief channel 8 is provided as an outwardly open groove , which is covered by the sealing rubber 7a of the centering bell 7 in the pressed-on position, so that the opening 8a of the relief channel is at the lower end of the liquid nozzle 4 and the gas to be discharged flows from the annular space 9 to this opening 8a briefly and leads, for example, via a nozzle 10 to the relief valve 11, from the blow-off opening 11a of which practically moisture-free exhaust gas is discharged to the outside. When lowering the centering bell 7, the relief channel 8 is opened to the outside, so that any moisture in it does not get stuck in the channel but can get down over the tubular piece of the contact rubber 7a into the bottle. Further, no liquid can enter the discharge channel so that the spray quantity is significantly reduced for this reason, this type of training as opposed to the known discharge channels during the filling process. In addition, according to the invention, the liquid mouthpiece 4 can be kept small, so that there is little adhesive liquid here too, which, moreover, cannot get into the channel 8. The same applies to the liquid that comes from the gas lock 4b and can get down during the expansion process.
