Description

The invention relates to a device for bottling bottled water and can be used in everyday life, offices and in production.

Devices for bottling bottled water, the so-called Dispensers are widely used for dispensing purified drinking water in small portions. They have means for cooling and / or heating water, storage tanks and taps for draining.

A large number of dispenser designs are known for dispensing water from rigid twenty-liter reusable plastic bottles. To ensure free draining, the bottle is installed upside down, the neck of the bottle through a cylindrical element is connected to the heating and / or cooling systems of water and its delivery (see, for example, US 5328059, Campbell, 07/12/1994). To replace the water flowing from the bottle of water, an air supply tube is provided, equipped with an air filter that eliminates the pollution of water from atmospheric air during bubbling. The invention (WO 2007071935, WALTON et al., 28.06.2007 - the closest analogue) describes a device for draining liquid from an inverted bottle, in which the supply of compressed air is initiated by an air pump connected through an air filter and a check valve, which creates excess pressure inside large bottles. The device may include an air pressure switch to turn off the pump when the appropriate pressure is reached. Alternatively, the pressure switch can be replaced by a control valve. The purpose of compressed air is the location of the water drain valves at a higher height.

Dispensers described above provide for the use of hard bottles. At the same time, the market offers a large amount of bottled water, packaged in non-rigid bottles, for example, a volume of 5 liters, more convenient for consumers. However, such containers, mainly for single use, have a significant drawback - the loss of stability, expressed by the collapse of the bottle when the contents are drained.

A patent is made for a device for bottling bottled water from thin-walled plastic (0.15-0.5 mm) bottles with a volume of up to 10 l, which excludes deformation and collapse of the bottle’s walls, as well as reduces sounds from bubbling air bubbles when it is emptied. Patented dispenser is equipped with means for forced compensation of vacuum in the bottle.

A bottled water bottling device comprises a holder for installing an inverted plastic bottle, a cylindrical element for interacting with the neck of the bottle, having a channel for draining water into the tank and an air supply channel for the bottle connected to the air pump and control valve through a non-return valve. The cylindrical element is installed in the flange, which is the lid of the tank, and is made in the form of a beveled pipe; a channel for draining water into the tank is formed in the cavity of the pipe and connected to the holes on the bevel surface and the side surface of the pipe, the channel for supplying air to the bottle is located on the obtuse side, and the aforementioned holes are on the acute angle side and lie in the plane of symmetry of the pipe. At the same time, the air pump is designed with a capacity that makes it possible to drain water from the bottle without losing its stability while maintaining an overpressure control valve of 0.07-0.09 atm.

The device can be characterized by the fact that the air pump creates an excess pressure of 0.13-0.16 atm and provides a capacity of 4-5 l / min, as well as the fact that the bottles have a volume of 1.0 to 20 l, the thickness of the side wall is from 0 , 15 mm and are made of polyethylene terephthalate (PET).

The device can be characterized by the fact that the flange on the side of the beveled pipe has a recess, to the bottom of which the fitting is connected, as well as the fact that the flange is installed in the tank through the sealing element and is fixed by a clamping element in the form of a ring with latches.

The technical result of the invention is the ability to use thin-walled plastic bottles in a dispenser without losing their stability when draining water, as well as eliminating acoustic noise associated with counterflow of water and air during water analysis.

The invention is illustrated in the drawings, where:

figure 1 shows the design of the device, figure 2 is a beveled part of the pipe (enlarged).

The device comprises a housing 1, in the upper part of which there is a holder 2 (shown schematically) for installing an inverted bottle 3 of plastic. The bottle is equipped with a stopper 4 (or adapter), through which a cylindrical element 5 is inserted into it for interaction with the neck 6 of the bottle 3.

The cylindrical element 5 is installed in the flange 7, which is the lid of the tank 8 of cold water. Tank 8 is connected by a pipe 9 to a tank 10 of hot water. Means for heating and cooling water in the tanks 8, 10 in figure 1 are not shown and are known to specialists. Water is drained into glasses by means of taps 11, 12.

The system includes an air pump 13 connected through a check 14 and control 15 valves with a tube 16 for supplying air to the bottle 3. An air filter 17 can be used to clean the air.

The cylindrical element 5 is made in the form of a pipe with a bevel 19. A longitudinal through channel 20 and a cavity 21 are made in the pipe, which are not communicated. The cavity 21 from the side of the flange 7 is in communication with the tank 8, and from the side of the element 5 has an opening 23 on the surface of the bevel 19 and an opening 24 on the side surface of the nozzle. The holes 23, 24, as well as the channel 20 are in the plane of symmetry of the element 5. Accordingly, the through channel 20 is located on the obtuse side formed by the bevel 19, and the holes 23, 24 are on the side of the acute angle. It was experimentally established that the optimal hole diameters 23, 24 for thin-walled (0.15-0.5 mm) bottles are 3.5 and 5 mm, respectively. If the size of the hole 23 is smaller, then air will not pass through it during the initial filling of the tank 8 with water. If the sizes of the openings 23, 24 are larger than those indicated, then, both during the initial filling of the tank 8 and the current discharge, compression of the bottle is possible.

The channel 20 is connected to the tube 16 of the air supply from the air pump 13 through the inlet fitting 25 mounted in the flange 7.

The flange 7 is installed in the tank 8 with a seal 26 located in the groove of the flange. The neck of the flange 7 has a protruding edge 27, which rests on the flanging 28 of the tank 8. The flange 7 is fixed by a clamping element 29, having the shape of a ring with latches 30. In the bottom of the flange having a plate shape, there is a fitting 31 with a pipe 32 for draining into the pallet 34 possible water leaks when changing the bottle.

The air pump 13 is made with a capacity that provides the ability to drain water from the bottle without losing its stability (productivity 4-5 l / min at an overpressure of 0.13-0.16 atm). In this case, the control valve 15 is set at a pressure of 0.07-0.09 atm.

The device operates as follows.

If the bottle 3 has a stopper 4, which is not coordinated in terms of parameters with element 5, then it is replaced with an adapter. The bottle is installed on the dispenser with the pump 13 connected. During initial filling, the hot water valve 12 is opened, water flows through the opening 24 and cavity 21 into the tank 8 and, after filling the latter to the end face 35 of the tube 9, into the tank 10. In this case, the air from the tanks through the open faucet 12 goes into the atmosphere. Air is supplied to the bottle through the channel 20 from the air pump 13, compensating for the resulting vacuum. After filling the tank 10, water begins to flow from the faucet 12, and the faucet is closed. Then the tank 8 will be filled from the end face 35 of the tube 9, while the air from the tank 8 through the cavity 21 and the hole 23 will be squeezed out into the bottle 3. In the operating mode, the overpressure in the bottle is maintained by the air pump.

As a result of such a process of forced replacement of water with air, the bottle retains its marketable appearance, does not deform, and does not create crackling sounds characteristic of the presence of partial evacuation. This makes it possible, among other things, to use thin-walled (0.15-0.5 mm) single-use PET bottles (polyethylene terephthalate). In addition, the advantage of this device is that it eliminates the acoustic noise associated with the counterflow of water and air during the analysis of water.

The patented system, using forced filling of bottles with air when draining water (water-air replacement system WARS) with sealing of the air-water circuit, is primarily intended for filling water from thin-walled single-use bottles, but it can also be used for hard plastic vessels.
