New storage for preserving τοπ food liquids.

The invention relates to a method and a device for the preservation of food liquids and in particular to liquids which can spoil by oxidation in contact with atmospheric air.

In particular, the invention lends itself to the preservation of beverages and, in particular, of wine. This application is described as an exemplary embodiment, but is not intended to be limiting.

The preservation of beverages, such as wine, makes it necessary that the liquid be preserved in contact with the atmospheric air, the oxygen content of which is the source of the

Oxidation and the deterioration in the quality of the goods is. Under these conditions, the wine must be kept in closed containers and in the locked state: Barrels, barrels, carboys or bottles. For the individual However, this is disadvantageous for consumers, since it is necessary to avoid oxidation and deterioration of the wine is led to buy the product stored in relatively small quantities. This is because smaller units can have a one after the other and within a limited time after opening the bottle. It goes without saying that this Service is heavily involved in the price of the distribution of food, drink and especially wine.

The invention is based on the object of remedying the disadvantages outlined and of creating a device which the preservation of wine in medium quantities and consumption according to the need of a medium Family for about a month, and which is much better than the traditional one for this purpose Bottle. The invention is therefore intended to enable the consumption of quality wine in a family setting, with the disadvantages transport and the costs of storing them in individual bottles should be avoided.

For this purpose, according to the invention, a method for con-

Serving of food liquids considered, which spoil from oxidation in contact with air can, characterized in that the liquid, optionally in significant amounts and optionally in Disposable containers bought, for the stage of consumption is spent in a prismatic container attached to his Bottom has a drain tap, is open at the top and a protective cover for insulation for the liquid level with respect to air, which is guided displaceably in the vertical direction and the liquid level when it is lowered, it follows when liquid is withdrawn through the tap.

Under these conditions, the food liquid can be bought in containers with flexible walls, which represent a cheap disposable container and the packaging, transport and distribution of liquid in large quantities Allow amount, but this container is not used as a disposable container in the area of daily consumption will.

Other features and advantages of the invention are as follows Description discussed including an embodiment with reference to a drawing. This represents a cross-section through a container according to the invention, which is shown in principle, with numerous modifications

709841/0748

cations and adjustments, especially in aesthetic terms, can be made without departing from the scope of the invention.

The container wall consists essentially of thick glass with a low coefficient of thermal expansion, in particular fireproof Glass. The container 1 is essentially cylindrical in shape and has an outlet line 2 at its bottom in which a cock 3 sits. The liquid, for example wine, can thus be drawn off as it is consumed will. According to the invention, the container 1 has a protective cover 4 in the form of a movable plug or a plate, the size and shape of which allows the displacement inside the container 1 and accordingly corresponds to the cross-section of the interior of the container. In the present case, the container has a cylindrical shape, and therefore, the protective cover 4 has a circular shape. On the circumference, the protective cover 4 has a seal 5, which consists for example of a good sliding plastic of the polytetrafluoroethylene type and at the same time a what friction along the smooth walls of the container 1 made of glass as well as a good seal of the space of the container 1 achieved below the protective cover. The seal 5 thus enables the protective cover 4 to be inserted from above and the linear vertical displacement in the vessel.

To the vessel 1 with food liquid, for example To fill wine, the protective cover 4 is moved by means of the sliding device deducted, which consists essentially of a cross member 6 and a spindle 7. When the vessel 1 is filled with liquid up to the vicinity of the upper edge, the cross member 6 is on the edge 12 of the vessel 1 put on and lowered the protective cover 4 by turning the spindle 7. The protective cover 4 is due to the low Game of the seal 5 held in sealing contact with the inner sides of the walls of the vessel. The sinking the protective cover 4 up to the liquid level 8 is facilitated by the fact that the cover 4 and air trapped in the liquid level is discharged via a line 9. In line 9 there is one Closure device, for example a tap 10. In order to be able to lead out the air better, the protective cover is 4 arched, which guarantees no air pocket between the liquid and the protective cover. When the air has completely escaped and the protective cover 4 comes fully into contact with the liquid, it rises this through the line 9, which is designed for example in the form of a glass pipette, and this is visible Event indicates that no more air is trapped between the protective cover and the liquid 8. It can now the cock 10 can be closed. In order to avoid that a jet of liquid gushes out of the line 9, one is

Chamber 11 is provided, which makes it possible to react in good time, when the liquid rises in line 9. After this work, the liquid 8 is hermetically sealed and kept from contact with air.

According to the exemplary embodiment shown, the displacement device of the protective cover 4 can be from the cross member and the screw spindle 7 are formed, which cooperates with a thread in the cross member 6. The cross member 6 can be pulled off the edges of the cylindrical vessel 1 simply by sliding it sideways. The rotation the spindle 7 is made possible by a handle 13. The lower end 14 of the spindle 7 sits in a cage 15, with a connecting device 16 including a spring 17, a flexible connection between the spindle 7 and Protective cover 4 manufactures. In this way, a certain buffer effect can be achieved, and also a certain one becomes Maintain pressure on the protective cover without the screw spindle 7 constantly having to be readjusted. in the The user can turn the handle 13 from time to time to measure how the liquid is drawn off via the line 2 and lower the liquid under a certain pressure of the protective cover 4.

Numerous variants of the elements described can be made, in particular with regard to the lowering limit.

709841/0746

direction of the protective cover. This lowering device can be operated by a simple handle on the upper end of the protective cover exist, the pressure being carried out by hand by the user in proportion to the withdrawal of liquid through the line 2 (if the liquid does not drain properly, you have to press the handle slightly).

The line 2 can also pass through a pipe to a higher one Be raised level of the container 1 in order to facilitate the transfer into a drinking vessel. In the illustrated embodiment the vessel must be arranged on the edge of a carrier plate in order to accommodate the receiving vessel (glass, carafe, Bottle or jug) under the outlet opening of the line 2 to be able to hold. Accordingly, if the line 2 in the sense of a Gooseneck is shaped, the liquid flows off at a higher level, and you can place the vessel 1 on a table and remove the liquid at the end of the gooseneck.

The glass walls can be colored and in particular consist of smoked glass to prevent the liquid from penetrating To keep light. The walls can also contain suitable inscriptions for decoration, advertising or the like. That Vessel 1 can also be arranged inside a protective container be who modifies the whole thing and, if necessary, embellishes it.
