Abstract

To decrease the air-space above the liquid in a part-filled container of beverage, an inflatable disc or bag is provided to float on top of the beverage, thereby inhibiting its deterioration. The bag is inflated by a pump via a valve, the pump being removable to allow deflation of the bag and extraction from the container.

Description

SPECIFICATION The container with inflatable disk or bag separating liquid from the air above so as to improve taste and strength of spirits and alcohol-free beverages Whisky, wine and other spirits as well as alcohol-free beverages are considerably worsened in taste and strength if they are left in the same bottle or other container after its opening. This effect appears due to increase in the above-liquid empty space, so that the more volatile components which are mainly responsible for the taste and aroma of the beverage evaporate at an increased rate and the liquid is left relatively poorer in those components. In many cases even an unexperienced drinker can easily notice the difference between a drink from a newly opened bottle and that which was kept for some time.

The purpose of the proposed invention is to decrease the volume of above-liquid air-filled space in a part-filled bottle of beverage using inflatable disc or bag.

The device consists of a rubber bulb connected with a pipe suspended from the neck of the bottle (Fig. 1). The latter has an inflatable disk or bag at its other end which, when inflated, is tightly pressed against the walls of the container so as to effectively keep air from beverage. The rubber bulb is connected to the pipe through an air valve or nipple preventing reverse flow of air pumped into disc or bag.

By screwing off the nipple the bag or disc is def!ated and can be removed from the container so that the latter can be, if needed,sclosed by a conventional cap.

The bag above its lower disc-shaped part can have any particular form or figure and thus be used for decorative purposes.

Any air pump can be used instead of the rubber bulb for inflating the bag which can be made of neutral material not affecting quality of beverage.

Claims (Filed on 6th May 1983) 1. A container for containing a beverage, which is constructed so that the volume of air therein in contact with the beverage can be minimized after the bottle has been opened.

2. A container as claimed in Claim 1, which is a bottle containing an inflatable disc or bag which when inflated is pressed against the walls of the container close to or floating on the surface of the beverage.

3. A container as claimed in Claim 1, substantially as shown in the drawing.
