METHOD OF PACKAGING LIQUID PRODUCT Russian patent published in 2014 - IPC B65B3/18 B65B31/02 

FIELD: packaging industry.

SUBSTANCE: invention relates to packaging of liquid product, such as a food product, particularly a product, which is sensitive to oxygen, into the container with the low oxygen content, having an opening. The method comprises removing air from the container by filling it with liquid to a nominal volume in the unregulated atmosphere, placing the filled container in the non-oxidising atmosphere consisting of at least one non-oxidising gas, the partial pouring of liquid from the container in the non-oxidising atmosphere so that at least one non-oxidising gas replaces the product poured out of the container. Then the container opening in the non-oxidising atmosphere is hermetically sealed. The installation for implementing the method comprises a flow-line production line, in which the means for filling containers with liquid product to a nominal volume in the unregulated atmosphere, a chamber with non-oxidising atmosphere filled with inert gas and containing means of conveyor feeding for moving the containers along, are located successively in the direction of forward movement of containers. At that in the chamber a device is located for emptying the containers by pumping. The installation also comprises a device for hermetic sealing the container opening, built in the chamber. The invention also provides the use of a method or the installation for packaging liquid food product.

EFFECT: group of inventions provides simplification of packaging and performance improvement.
