Description

CONTAINER FOR LIQUIDS MORE PARTICULARLY DRINKS The invention concerns a container for liquids, more particularly drinks, which container can be filled and emptied through a fitting and a container opening in the container bottom.

From German Patent Application DE-OS 27 36 281 a container of this kind is known, in which a foil bag is arranged for receiving the drink, such as beer for example. This foil bag, which is inserted into the container through the container opening before the fitting is attached to the container opening, opens out into a collar at the foil bag opening and is fastened, by its flange-like outwardly turned down collar, in the container opening between a flange plate of the fitting and two annular shells, which surround the collar and are fastened to the container bottom.

Containers of the type described in the introduction are known in the art, where the fitting is attached to the container opening not directly, but by means of a pipe section. As a consequence of the length of the pipe section and its diameter, as well as the internal width of the container opening, it is not possible to insert a foil bag through the pipe section and the container opening into the known container and to fasten it by its collar. This known container therefore cannot be equipped with a foil bag.

The present invention seeks to provide an improved container of the last-mentioned type equipped with a foil bag, the container having, attached to the container opening, a pipe section with a fitting releasably fastened thereto.

According to the present invention there is provided a container for liquids, wherein: a) the container is provided with a container opening for filling and emptying; b) a pipe section issues from the container opening; c) a detachable fitting is located at the end of the pipe section remote from the container opening; d) the container has an additional container opening; e) a foil bag, which can be inserted into the container through the additional container opening, is positioned in the container; and f) the foil bag is connected in a detachable manner to the fitting by means of a tubular piece which extends through the pipe section.

The additional container opening, which can be constructed for example as a manhole, makes it possible to insert the foil bag into the container quickly and in a simple way. From there, the tubular piece is pushed or pulled easily and quickly through the pipe section until it can be attached with its free end onto the fitting.

The tubular piece is preferably constructed as a foil tube integral with, or fixedly connected to, the foil bag. Such a foil tube is introduced from the inside of the container into the pipe section and then pulled from outside the container through the pipe section. A flexible tubular piece of this kind is especially suitable for such containers where the pipe section is bent by means of a knee piece. Such a construction is advantageous for a pipe section attached to the container bottom.

In accordance with a further embodiment of the invention, the tubular piece comprises a first tubular piece section, fastened onto the foil bag, and a second tubular piece section which can be connected to the fitting and to the first tubular piece section, preferably by means of a snap connection, bayonet connection or screw connection. Such a second tubular piece section, constructed so that it is separate from the first tubular piece section, can be pushed from outside the container through the pipe section and the connection to the second tubular piece section can be effected from the inside of the container.

The second tubular piece section is preferably constructed with a tubular knee piece corresponding to the knee piece of the pipe section. In this connection, the second tubular piece section can be constructed as a whole in a flexible manner or it can be constructed so that it is generally rigid but flexible in an elastic manner in the curvature region of the tubular knee piece.

In accordance with a further embodiment of the invention, the second tubular piece section is straight, is stiff or rigid and is constructed with a closed end having a tubular opening in its wall, for the connection to the first tubular piece section.

Such a second tubular piece section can especially easily be pushed through the pipe section and attached to the first tubular piece section of the foil bag.

For a better understanding of the present invention reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a section of a preferred first exemplary embodiment of a container according to the invention with foil bag; Figure 2 shows the lower part of the foil bag of Figure 1; Figure 3 shows the lower part of a foil bag in accordance with a second exemplary embodiment; and Figure 4 shows the lower part of a foil bag in accordance with a third exemplary embodiment.

The container 1 represented in Figure 1 is provided for receiving a drink containing carbon dioxide, for example beer, and is constructed as a cylinder 2, resting on supports 3 and having a container bottom 4 formed in a convex manner and an upper cover 5 which is likewise formed in a convex manner. A container opening 6 is provided in the container bottom 4 for filling and emptying the container 1. A pipe section 8, extending horizontally beneath the container bottom 4 and fastened to the latter by a holder 7, comprises a 900-knee piece 9, which opens out into the container inner through the container opening 6. A fitting 10 is fastened onto the free end of the pipe section 7 in such a way that it can be replaced.

A manhole 11, indicated by means of a cover, is constructed in the cylinder wall 2 as an additional opening. In the upper cover 5 of the container 1 an additional fitting 12 is installed which serves to supply a pressure gas to the container inner, the gas being CO2 in the present exemplary embodiment.

A foil bag 13 is arranged in the container inner and opens out through a foil bag opening 14 into a tubular piece 15, which passes through the pipe section 8 and is connected to the fitting 10. The foil bag 13 is filled with beer 16 and, although drawn separately for the sake of better representation, it rests against the cylinder wall 2 and the container bottom 4 and with its tubular piece 15 against the walls of the pipe section 8. Between the upper end of the foil bag 13 and the upper cover 5 of the container 1 there remains an intermediate space 17 filled with CO2.

The tubular piece 15 represented in Figures 1 and 2 is constructed as a flexible foil tube integral with the foil bag 13. With each new filling of the container 1 the foil bag 13 and the fitting 10 are replaced in order to make sure that the beer 16 which has been poured in germ-free also remains germ-free.

For this purpose, the fitting 10 is detached from the pipe section 8 and the connection to the tubular piece 15 is thus released and then the foil bag 13 is removed from the container 1 through the manhole 11. After inserting a new foil bag 13 in the same way into the container, the tubular piece 15 is pushed through the knee piece 9 and then grasped from the free end of the pipe section 8, for example by means of a holding arrangement located at the end of a rod, and pulled through the pipe section 8 up to its free end.

Thereafter, a new fitting 10 is put onto the free end of the pipe section 8 and the connection to the tubular piece 15 is thus produced. Subsequently, air with a pressure of about 0.8 bar is introduced into the container 1 through the additional fitting 12 and then the beer 16 is introduced into the container through the fitting 10 against the air pressure in the container 1. The air pressure keeps the carbon dioxide in the beer in solution and thus prevents foaming of the beer. After the foil bag 13 is filled, whereby for reasons of safety the intermediate space 17 must have a minimum volume, the air in the intermediate space 17 is replaced by CO2 through the additional fitting 12 with a pressure likewise of about 0.8 bar. In contrast with atmospheric oxygen, CO2 as an inert gas prevents an impairment of the taste of the beer.

The tubular pieces 15 represented in Figures 3 and 4 are constructed in two parts with a first tubular piece section 18 and a second tubular piece section.

The first tubular piece section 18 is fastened in one piece onto the foil bag 13 and can be connected to the second tubular piece section by means of a snap connection which is only shown in Figure 4. The snap connection consists of an annular projection 19 on the first tubular piece section 18 and an annular groove 20 on the inside of the second tubular piece section for receiving this annular projection 19 in a liquid-tight manner. The first tubular piece section 18 and at least the end region of the second tubular piece section can be moulded in an elastic manner to be able to effect and release the snap connection.

As shown in Figure 3, in the second embodiment the second tubular piece section 21 is provided with a tubular knee piece 22, corresponding to the knee piece 9 of the pipe section 8. The inside of the tubular knee piece 22 having the annular groove of the snap connection is not shown. The remaining part of the second tubular piece section 21 is constructed essentially rigidly with a straight path, while the curvature region of the tubular knee piece 22 is constructed so as to be similar to a corrugated tube and thus is flexible in an elastic manner.

As shown in Figure 4, in the third embodiment the second tubular piece section 23, which is constructed straight and as a whole rigidly, is closed at its end which is at the foil bag side by means of a stop plate 24 and is provided directly next to it with a tubular opening 25, into which the first tubular piece section 18 can be inserted. The annular groove 20 is constructed in the tubular opening 25.

When the container 1 is to be filled anew with beer, the process takes place in the manner already described with the difference that first of all the second tubular piece section 21 or 23 is pushed into the pipe section 8 from its free end until it reaches the pipe knee piece 9 and then the first tubular piece section 18 of the foil bag 13 inserted into the container inner, is fitted into the tubular knee piece 22 or the tubular opening 25 of the second tubular piece section 21 or 23 and in this way the snap connection is produced.

The second tubular piece section 23 being straight can be pushed through the pipe section 8 easily.

Neither does the pushing-through of the second tubular piece section 21 with the tubular knee piece 22 present any difficulties, since it assumes a straight shape during the pushing-through, as a consequence of the elastically flexible curvature region of the knee piece 22.
