UA95756C2 - Mechanism for attaching plastic bottle neck to pouring channel of device for manual dispensing foam and/or carbonated beverages - Google Patents

Abstract

The invention relates to the food industry, in particular to commercial equipment and can be used for dispensing beer and other beverages from a pressurized container into plastic bottles in retailing trade, shops, restaurants and bars. A mechanism for attaching a bottle neck to an end face of pouring channel wall comprises a hollow body with a control handle, which is rotatabty disposed around the pouring channel wall, and a spoon which is provided with a slot corresponding to the bottleneck size and is mounted in such a way that it is reciprocatingly axially movable in front of the open end of the pouring channel having an elastic sealing ring corresponding to the bottleneck size. The mechanism also comprises a hollow cylinder which is positioned between the pouring channel wall and the body in such a way that it is reciprocatingly axially movable and kinematically coupled to the pouring channel wall by means of a splined element. The spoon with groove is attached to the end face of hollow cylinder, a screw shaped slot is made in the hollow cylinder wall and a roller, which is fastened to the body with a handle by means of a pin, is accommodated in said slot. The mechanism has a removable springly elastic element, the shape of which corresponds to the inner surface of the spoon with groove and which is fastened in the groove of spoon.

Description

The first is made in the form of a nozzle 12 with an axial through channel 13 and a cylindrical part with a screw drain channel 14 on the outer surface.

The mechanism for attaching the neck of a plastic bottle to the wall 7 of the drain channel 14 (Fig. 1, C and 4) contains a hollow body 15 with a control handle 16, located around the wall 7 of the drain channel 14 with the possibility of rotation and a spoon 17 with a groove 18 corresponding to the size of the neck PET bottle, installed with the possibility of axial reciprocating movement in front of the open end of the drain channel 14, which has an elastic ring seal 19, corresponding to the diameter of the neck of the PET bottle. Between the wall 7 of the drain channel and the body 15 of the mechanism, an empty cylinder 20 is placed with the possibility of axial reciprocating movement and is kinematically connected to the wall 7 of the drain channel with the help of a slotted element 21. The spoon 17 with a groove is attached to the end of the hollow cylinder 20, in the wall of which a screw slot 22 is made. A roller 23 is placed in the screw slot 22, attached with a pin 24 to the body 15. The PET bottle attachment mechanism has a removable spring-elastic element 25, made according to the shape corresponding to the inner surface of the spoon 17 with a groove 18 and fixed in the spoon behind with the help of a groove 26 made in it. The throttle valve 27 is installed in the housing 1 and is connected by its inlet channel to the through axial channel 13 of the nozzle 12.

The device for manual bottling of foamy and/or carbonated drinks, together with the mechanism for attaching the neck of the plastic bottle to the drain channel, works as follows. Take a plastic bottle, insert the spoon 17 into the groove 18 and turn the handle 16 together with the body 15. At the same time, the roller 23, moving along the screw slots 22, moves the cylinder 20 with the spoon 17 up. The spoon 17 presses the end of the neck of the PET bottle to the end of the wall 7 of the drain channel 14 and they are hermetically connected due to the elastic ring element 19 (without turning the PET bottle). At the same time, the throttle 27 is closed. The handle 16 of the three-way valve 10 is in a (neutral) vertical position. Then the handle 16 of the three-way tap is deflected by 20 degrees (in the opposite direction from the operator). At the same time, the channel 2 is connected to the gas through the outlet channel 8, the axisymmetric cavity 6, the screw drain channel 14 with the internal volume of the bottle. At the same time, CO2 gas from the cylinder enters the bottle, the pressure in which is equalized to the pressure in the isobaric container. Next, tilt the handle 16 of the three-way faucet 10 by 40 degrees in the opposite direction. At the same time, channel 4 is connected to the drink through the outlet channel 8, the axisymmetric cavity b, the screw drain channel 14 with the internal volume

PET bottles. Since the pressure in the PET bottle and the isobaric container is the same, the drink does not enter the specified container. When the throttle 27 is opened, CO" gas is pushed out of the PET bottle into the atmosphere through the axial channel 13, the inlet and outlet channels of the throttle 26. A pressure difference is created in the isobaric container and the PET bottle, due to which the drink fills the bottle. Passing through the screw drain channel 14, the drink is fed in the form of a conical film to the walls of the neck of the PET bottle under the action of centrifugal forces and then smoothly flows down its walls, preventing foaming. Elimination of foaming is also ensured by the creation of gas pressure in the filling system and above the surface of the drink in the plastic bottle, which exceeds the saturation pressure of the gas dissolved in the drink. After filling the bottle with a drink, in order to stop its further flow from the isobaric container, the handle 16 of the three-way tap 10 is turned to the neutral (by 20 degrees) initial vertical position. The remaining gas in the neck of the PET bottle and the partially dissolved gas released from the drink are removed through the axial channel 13 of the nozzle 12 and the channels of the throttle 27 into the atmosphere.

After equalizing the pressure in the PET bottle to atmospheric, turn the handle 16 in the opposite direction, disconnecting the end of the wall 7 of the drain channel from the neck of the PET bottle, which is removed from the filling device, closed with a stopper and released to the consumer. When filling PET bottles with a short neck, the spring-elastic element 25 is inserted into the groove 25 of the spoon 17. Then the mechanism works as described above.

Thus, the fastening mechanism allows you to manually quickly and hermetically connect the neck of a plastic bottle to the end of the wall of the drain channel of the device for manual filling of foamy and/or carbonated drinks without turning the bottle, which significantly increases the convenience of using the device. The use of a removable spring-elastic element in the mechanism allows you to fill PET bottles with both short and long necks, which expands its functionality.
