In a device used for filling liquids in portions into bottles, cans or similar receptacles and having a plurality of volumetric dosing chambers, which are arranged on a rotor and which are connected to a storage reservoir for the liquid via a controllable inlet valve and to a filler neck via a controllable outlet valve, at least two sensors responding to different filling levels are arranged in each dosing chamber, the sensor arranged on a higher level closing the inlet valve when the filling level has risen to a specific height, and the sensor arranged on a lower level closing the outlet valve when the filling level has dropped to a specific height. The volume of one portion of the liquid to be canned or bottled is thus defined in a simple manner by the vertical distance between the two sensors, or rather the measuring points of said sensors.

The invention concerns a container filling machine with a supply chamber for a fluid and a compressed gas, onto which at least one filling device is attached. This device possesses a discharge opening, a fluid valve, a compressed gas valve body arranged on its valve body and a probe which determines filling height held on this compressed gas valve body. It leads out of the lower end of the compressed valve body in a gastight arrangement. Hereby is a container filling machine achieved with higher filling accuracy, greater versatility, more cleanability and low production costs.

Container filling machine

A process and a device for the sterile filling of beverage liquids. In the process and device a bottle is sterilized by passing steam into it through a short feed pipe. All other phases such as CO.sub.2 flushing, counter-pressurizing and return gas discharge also take place through the feed pipe. During the filling process the liquid to be filled flows into the bottle around the feed pipe.

Process and device for the mixing of beverage components

Apparatus for mixing beverage components, in particular sirup and water, having two separate reception chambers which receive the components and are each provided with an inlet and an outlet. To improve the mixing results in such an apparatus in a constructionally simple way, the inflow of a first component, in particular water, to a first reception chamber is first passed through a second reception chamber filled with a second component, in particular sirup, and then through a transition portion arranged between the first and second reception chambers, the transition portion having a reduced cross-sectional area in comparison with the cross-sectional area of the first reception chamber, before it flows into the first chamber. The component within the second reception chamber is the entrained in the component flowing into the first reception chamber. Thereafter the mixture of the components is discharged from the first and second reception chambers by flowing it out of the second reception chamber.

A device for filling PET bottles employs a cam driven vertically movable carriage mounted on the outside of the liquid storage tank adjacent each filler valve inside of the tank. A bracket mounted to the lower end of each carriage has a flat plate extending horizontally under a filler valve. A bottle gripper, having an open side slot for engaging under the collar near the mouth of a PET bottle, is suspended on two bolts which extend slidably through the flat plate. Normally uncompressed springs are interposed between the heads of the bolts and the top of the plate to hold the gripper against the bottom of the flat plate. A cam lifts the carriage after the gripper engages a bottle under its collar to initiate a seal between the bottle mouth and filler valve and as the carriage continues upward by a small amount for latching to the tank. The springs are compressed and a gap forms between the flat plate and the gripper. The plate compresses the spring which generates the force to increase the sealing force. The carriage latching is frictional and is not maintained to suspend a bottle unless the carriage is loaded gravitationally by the weight of a bottle.

Continuously operating rotational bottle filling installation

An apparatus for filling bottles or other containers under the influence of counterpressure by of a filling unit, pressurized gas is led into the bottle after terminating the inflow of liquid, with the pressurized gas valve and liquid valve being closed and with a bypass of the gas return tube, and the liquid that thereby remains above the lower open tip of the gas return tube is expelled into a space having a lower pressure than exists in the bottle.

In apparatus for filling cans with beverage the can is coupled to the filler valve and purged of atmospheric air with a mostly inert gas and air mixture derived from the space of the liquid in a storage tank. When the exhaust valve is closed, another valve opens to permit pure inert gas stored in a reservoir to flow into the can and pressurize it to slightly above atmospheric pressure but below the pressure in the storage tank. A pre-pressurization valve is then opened to let some of the inert gas and air mixture in the storage tank flow to the can which is occupied by the substantially pure inert gas so practically none of the downflowing gas and air mixture from the storage tank enters the can although it fills the chamber to which the can is connected and thereby pressurizes the can. When the can pressure and storage tank pressure become equal, a liquid control valve opens to drain liquid from the tank into the can. Liquid flow is shut off in a conventional manner when the liquid level in the can reaches the lower tip of the pre-pressurizing gas return tube. As the liquid beverage flows into the can it displaces the most pure inert gas into the space above the liquid in the storage tank so as to increase the concentration of the inert gas in the storage tank.

In a method for filling bottles or other containrs under the influence of counterpressure by means of a filling unit, pressurized gas is led into the bottle after terminating the inflow of liquid, with the pressurized gas valve and liquid valve being closed and with a bypass of the gas return tube, and the liquid that thereby remains above the lower open tip of the gas return tube is expelled into a space having a lower pressure than exists in the bottle.

At the upper side of the star wheel bottle feeder of a bottle capping machine, a chamber which encompasses the bottle neck is attached at each pocket in the periphery of the star wheel in which the bottle neck is registered as it is transported in a circular orbit. At the top side, the chamber has an opening for a reciprocating sealing element which revolves with the star wheel. The chamber has a circular internal bore and an opening on its radially outermost side that allows bottles to be passed through it and into a pocket on the star wheel. There is a nozzle slot at the radial inside of the chamber diametrically opposite from the outside gas exit opening. The gas input slot has an elbow connected to it and the elbow is connected to a gas distributor valve which is, in turn, connected to a source of carbon dioxide. Because the neck and mouth of each bottle is captured within the chamber, the opening of the bottle and the underside of the crown cap are purged of air which is replaced with inert gas before the cap is crimped onto the bottle.

Container closing machine

A method and apparatus for filling a bottle with an oxygen sensitive liquid such as beer in which the bottle is pre-evacuated, pressurized with pure CO.sub.2, over-filled with liquid at constant pressure and then brought back to the proper fill level by injecting pure CO.sub.2 and forcing the excess back into the gas pressurized liquid storage tank while the bottle is still coupled to the filling head. After uncoupling, the bottle is transported to under a closure cap applying device at which there are nozzles that project CO.sub.2 under the device and over and around the mouth of the bottle so the space even within the cap is purged of air. The CO.sub.2 used for purging is adequately free of air since it is taken from the storage tank to which CO.sub.2 is returned from the bottles as a result of filling liquid displacing the CO.sub.2 gas which is diluted only to the extent that pre-evacuation is not perfect.

Method and apparatus for filling bottles or the like with liquid

Containers such as bottles, which are to be filled with liquid from a tank pressurized with non-oxidizing gas, are coupled to a filling device and evacuated of air that is discharged to the atmosphere. Next gas from the tank is fed to the bottles. When gas pressure in the tank and bottle equalize, the liquid flows by gravity into the bottle to displace the gas and return it to the tank. After filling with liquid is cut off a charge of pure non-oxidizing gas is injected in the bottle to fill it to the top with pure gas. Excess pure gas is fed back into the tank to make up for the dilution of the gas that results from the evacuation of air from the bottles being necessarily imperfect. The bottles are uncoupled from the device after they are filled with pure gas and they are then sealed.

Method and device for filling containers

In the containing filling device the tank for the liquid to be dispensed into containers has gas somewhat over atmospheric pressure applied to the liquids surface. Each filling station has an outlet leading to the container being filled, a gas valve coupling the tank to the container and a fluid valve coupling the tank to the conveyor. The liquid above the tip of the tube that leads from the gas valve is forced back into the tank by means of gas pressure injected into the outlet after the filling operation is ended. In which case the fluid valve is forced closed and the gas valve is forced open. Because of the forced open gas valve the injection of gas takes place at very low pressure differential, causing neither disturbance of the liquid in the container and in the tank nor blow out of liquid below the level of the tank of the gas return tube.
