Procedure for filling alcoholic beverages, in particular wine, into stand-up type pouches made from polylaminate material

Abstract

A procedure for filling alcoholic beverages, in particular wine, into stand-up type containers made from polylaminate material comprises the following operational steps: a) preparing a stand-up type container; b) mechanically opening the upper part of the container (21) to form a filling space; c) injecting an inert gas in the filling space with the aim of reducing the presence of oxygen in the space; d) introducing a predetermined quantity of an alcoholic beverage, in particular wine, inside the space; e) closing without sealing the open edges of the container (21); f) sealing the upper part of the container (21) to form a hermetically closed container and containing an alcoholic beverage, in particular wine. The polylaminate material used comprises a cellulose layer having a basic weight of not less than 150 g / m2; the mechanical opening comprises the mechanical opening from the inside of the mouth of the container (21) and the deep injection into the container of a high pressure jet of air; step f) is performed inside a sealing station (38) in which a first sealing unit (55) performs a hermetic sealing operation fulling sealing a shaped strip inside the upper portion of the container (21).

Description

TECHNICAL FIELD[0001]This invention relates to an industrial procedure for filling alcoholic beverages, in particular wine, into stand-up type pouches made from polylaminate material. This invention also relates to a filling machine designed to perform the procedure.[0002]The machine according to the invention comprises certain operating stations which are able to perform various advanced functions during the filling steps, at the end of which there is a final product of high quality, which is especially necessary in the presence of high quality wines.[0003]This invention can be applied in the field of machines for filling beverages such as wines or the like in containers and in particular in paper-based polylaminate containers.BACKGROUND ART[0004]It is known that machines currently exist on the market allowing automation of the operations for packaging a wide range of food products in a wide range of containers made from a wide range of materials.[0005]One of the containers most co...

AI Technical Summary

Benefits of technology

The present invention provides a procedure and a machine that can improve the quality of containers made for use. This machine allows for higher standards of quality and consistent production compared to previous solutions.

Problems solved by technology

It has been found that these machines lack means which allow the perfect shape of the finished container to be obtained and also means which allow the environment for injection of the liquid and the subsequent environment for closing the container to be kept perfectly aseptic.

Due to these drawbacks, the prior art machines do not allow finished containers with a high quality to be obtained and consequently the beverages contained therein are easily perishable especially if they are alcoholic beverages, in particular wine, which is notoriously much more subject to oxidation phenomena and deterioration, compared with other beverages.

Moreover, in the particular case of containers filled with alcoholic beverages, in particular but not exclusively wine, the polylaminate materials conventionally used in the industry for making containers for food products are not adequate to constitute a container which is at the same time robust, sterile and perfectly sealed from the outside environment.

In the opinion of the Applicant, there are no systems which are able to produce robust, sterile and perfectly sealed containers filled with alcoholic beverages, in particular wine, on a large scale.
