    DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

    [0097] FIG. 1A shows a container 12 of a liquid container (or fluid tank) according to the invention, comprising a bottom section (not referenced) and a substantially cylinder-shaped sheath (or mantle) section 26. The container 12 shown in FIG. 1A is manufactured in a one-piece design of a mono block of a solid natural stone. In an (in FIG. 1A upper) end face of the sheath section 26, there is formed a plurality of anchoring holes (or bores) 74 for anchoring a dowel (or rawlplug) or another fastener means.

    [0098] FIG. 1B shows the container 12 of FIG. 1A that has been manufactured in a one-piece design of a mono block 20 of a solid natural stone 18, on which in addition a lid (or cap) 36 is arranged, which is also produced in a one-piece design of a mono block of a solid natural stone. In a circumferential section of the lid 36 there is formed a plurality of through-holes 76 which are formed in rapport (or repeating pattern) with the anchoring holes 74 in the upper end face of the sheath section 26 of the container 12. A sealing 72, such as a sealing ring respectively an O-ring, is put on the upper end face of the sheath section 26 of the container 12. A plurality of lock screws 78 is respectively led through each of the through-holes 76 and is respectively screwed tightly into a dowel (or rawlplug) arranged in each one of the anchoring holes 76, such that the seal 72 is compressed and a gap that is present between the end face of the sheath section 26 of the container 12 and the inner (in FIG. 1B lower) surface of the lid 36 may be sealed. A filling port (or fill hole) 68 is further provided in the lid 36 for filling in a liquid into the container 12.

    [0099] A container 12 of a one-piece design, such as shown in the FIGS. 1A and 1B, having a wall thickness of approximately 10 cm and a sheath diameter of approximately 150 cm has been manufactured as a first prototype and has been used in a wine-growing estate in the production of wine (white wine).

    [0100] FIGS. 2A and 2B show a second prototype of a liquid container 10 according to the invention, which has been improved in respect of the producibility (i.e. simplifying the manufacturing). The liquid container 10 shown in the FIGS. 2A and 2B comprises a container 12 that is constructed of a disk-shaped bottom section 22 produced in a one-piece design from a mono block of a solid natural stone 18, and a substantially cylinder-shaped sheath section 26 that has also been manufactured in a one-piece design of a mono block of a solid natural stone 18. In an (in FIG. 2A upper) end face of the sheath section 26, there is provided a plurality of anchoring holes 74 for anchoring a dowel or another fastener means. In a circumferential section of the lid 36, there is provided a plurality of through-holes 76 arranged in rapport with the anchoring holes 74 formed in the upper end face of the sheath section 26 of the container 12. In addition, a filling port (charging hole) 68 for filling in of liquid is formed in the lid 36.

    [0101] As is shown in FIG. 2B, the liquid container 10 further comprises a first liquid outlet 44 conceived as a so-called clear-liquid-outlet (i.e. an outlet for clear liquid) that is formed in the sheath section 26 at a height of approximately 12 to 25 cm (in the example of the second prototype: 20 cm) above the upper side of the bottom section 22 and is provided with an openable and closable outlet valve (not referenced), such as a drain cock, that is produced from stainless steel. The first liquid outlet 44 serves for draining (or withdrawing) liquid that has been produced completely (or finished) out of the liquid container 10, whereby a possible deposit at the bottom of the barrel may remain in the liquid container 10 below this liquid outlet 44. The liquid container 10 shown in FIG. 2B further comprises a second liquid outlet 46 that is formed in the bottom section 22 and is provided with an openable and closable outlet valve (not referenced), such as a drain cock, that is produced from stainless steel. The second liquid outlet 46 serves for draining of liquid, such as the liquid which contains the bottom deposit residues, or for draining a cleaning liquid e.g. in the context (or course) of a cleaning process. Both the first and the second liquid outlet 44 and 46 are manufactured from food safe (or non-tainting) materials and comprise solely components, such as seals, that are also manufactured from food safe materials.

    [0102] The liquid container 10 shown in FIG. 2B further comprises a first seal 70 that is formed substantially ring-shaped, and that may for example be formed from an adhesive (or agglutinant) or a joint (or interstice) sealant and that is for sealing a gap present between an (in FIG. 2B lower) end section face of the sheath section 26 and a (in FIG. 2B upper) surface of the bottom section 22. The liquid container 10 further comprises a second seal 72 that is formed substantially ring-shaped, that can for example be produced from foamed rubber and that serves for sealing a gap present between an (in FIG. 2B upper) end section face of the sheath section 26 and a (in FIG. 2B lower) surface of the lid 36. Both, the first seal 70 and the second seal 72 are produced from food safe materials.

    [0103] FIG. 2C shows a lid 36 for a container 12, which lid differs from the lid 36 shown in the FIGS. 2A and 2B in that it is not formed in a one-piece design but comprises a lid bearing layer 40 and a lid covering layer 42 that is connected two-dimensionally therewith. In this design, only the lid covering layer 42 is made of a solid natural stone. The lid bearing layer 40 is made of concrete or of another curable artificial stone. A filling port (or charging hole) 66 is provided in the lid 36 for filling in of liquid.

    [0104] In correspondence to the lid 36 shown in FIG. 2C, also the bottom section 22 shown in the FIGS. 2A and 2B may be modified such that it is not formed in a one-piece design, but comprises a bottom section bearing layer (not shown) and a bottom section covering layer (not shown) that is two-dimensionally connected therewith. In this design, only the bottom section covering layer may be made of a solid natural stone, and the bottom section bearing layer may be formed of concrete or another curable artificial stone.

    [0105] Also in the container 12 that is shown in the FIGS. 1A and 1B and that has been processed out of a mono block of a solid natural stone, there may be provided in the sheath section 26 a first liquid outlet (not shown) comprising an openable and closable outlet valve, such as a drain cock, in a predetermined distance to (respectively height above) the bottom section 22, for example conceived as the clear-liquid-outlet (or outlet for clear liquid) and a second liquid outlet (not shown) that is provided in the bottom section 22 and comprises an openable and closable outlet valve, such as a drain cock (or drain valve), for example as a cleaning outlet (or outlet for a cleaning fluid).

    [0106] It should further be noted with reference to the FIGS. 1B and 2B that it is important during a use of the liquid container 10 shown, for example in the production of beverages, that a liquid outlet (not shown) provided in the bottom section 22 and comprising an openable and closable outlet valve arranged at a lower side (or bottom side) of the bottom section is accessible and can be handled (or activated), that a space below the liquid container 10 is accessible and can be cleaned, and that an air circulation is possible in the space below the liquid container 10. In order to enable all this, it is conceived to arrange the liquid container 10 on a sub-structure (or base construction). A suitable sub-construction may comprise two walings (or crossbars) (not shown) made of stone, i.e. columns made of natural stone having a, e.g. triangular, quadratic or rectangular cross-section, on which bars the bottom section 22 of the liquid container 10 may be put on (or piled).

    [0107] In a use of the liquid container 10 shown in the FIGS. 1 and 2, such as in the production of beverages, it is also important that the liquid container 10 may be displaced from a first place of installation (site) to a second place of installation, if necessary, even in a state filled with a liquid. To this end, a forklift truck (or palette transporter) may be used. In order to enable the displacement of the liquid container 10, it may be conceived that openings (or recesses) respectively bores (not shown) that extend horizontally are provided, into which the gripper (or fork) of a forklift truck can engage in order to lift the liquid container 10.

    [0108] In FIG. 3, there is illustrated an embodiment of the method according to the second aspect of the invention. The method serves for manufacturing a liquid container (or fluid tank) for producing and/or storing liquids provided for drinking consumption. In the method, initially, a block (not referenced) consisting of a solid natural stone 18 is provided (implementation of the step (a)). Then, by means of a first hollow drill core drillbit (not shown) having a first outer diameter d.sub.1a=2*r.sub.1a, wherein r.sub.1a is the respective first outer radius, a substantially cylinder-shaped first inner wall surface 16-1 having a first inner diameter, that corresponds nominally to the first outer diameter of the hollow drill core drillbit, is drilled out. The cylinder-shaped first inner wall surface 16-1 that arises thereby may be conceived as an inner wall surface 16-1 of a first sheath section 26-1 of a first liquid container (implementation of the step (b)), either directly or, if applicable, after performing a surface conditioning step that is described further below.

    [0109] What is not shown in FIG. 3 is, that after the step (b), a bottom section (not shown) of a solid natural stone having a substantially plane surface, which is conceived as the bottom section of the inner wall surface of the first fluid tank, either directly or, if applicable, after performing a surface conditioning step, is provided (implementation of the step (c)) and is connected in a liquid-tight manner with the sheath section 26-1 at an end of the sheath section 26-1. Thereafter, a lid section (not shown) that is made of a solid natural stone and has a substantially plane surface, that is conceived as the lid section of the inner wall surface of the fluid tank, either directly or, if applicable, after performing a surface conditioning step, is provided and is connected releasably and in a liquid-tight manner with the sheath section 26-1 at its other end (opposite end) thereof.

    [0110] In the method illustrated in FIG. 3, a substantially cylinder-shaped drill core 26-2, 26-3, 26-4 of solid natural stone and having a first outer diameter is further produced as a further result of the drilling out using the first hollow core drillbit (step (b)). Thereby, the first outer diameter corresponds nominally to an inner diameter d.sub.1i=2*r.sub.1i (wherein r.sub.1i is the corresponding inner radius) of the first hollow drill core drillbit. In the substantially cylinder-shaped drill core 26-2, 26-3, 26-4 consisting of solid natural stone obtained in step (b), a substantially cylinder-shaped second inner wall surface 26-2 having a second inner diameter is drilled out, using a second hollow drill core drillbit (not shown) having a second outer diameter d.sub.2a=2*r.sub.2a, wherein r.sub.2a is the corresponding second outer radius that is smaller than the first outer diameter d.sub.1a=2*r.sub.1a by a predetermined value, and coaxially to the first bore performed with the first hollow drill core drillbit (in step (b)), such that a cylinder sheath consisting of solid natural stone arises, which sheath can be used as a sheath section 26-2 of a second liquid container, wherein the second inner wall surface of the cylinder sheath is conceived as the inner wall surface of the sheath section of the second liquid container (implementation of the step (d)), either directly or, if applicable, after performing a surface conditioning step.

    [0111] Then, by means of a third hollow drill core drillbit having a third outer diameter d.sub.3=2*r.sub.3, wherein r.sub.3 is the corresponding third outer radius that is smaller than the second outer radius by a predetermined value, and coaxially to the first and second bores performed in the steps (b) and (d), a third substantially cylinder-shaped third inner wall surface 16-3 having a third inner diameter is drilled out of the substantially cylinder-shaped drill core 26-3, 26-4 obtained in step (d), such that a cylinder sheath of solid natural stone that is usable as a sheath section 26-3 of a third liquid container arises, where the third inner wall surface of this cylinder sheath is conceived as an inner wall surface of the sheath section of the third liquid container (implementation of the step (e)), either directly or, if applicable, after performing a surface conditioning step. It is obvious, that the steps (d) and (e) can be repeated with respective further hollow drill core drillbits having successively smaller diameters.

    [0112] The FIGS. 4A to 5C illustrate further embodiments of the construction of a liquid container 10 according to the invention and a method according to the third aspect of the invention for manufacturing a liquid container 10 according to the invention.

    [0113] As is shown in the FIGS. 4A and 5A, in embodiments of the method according to the third aspect of the invention, a block of solid natural stone 18 that is formed substantially plate-shaped is provided initially, where this block has two plate surfaces 54 that are substantially parallel and opposite to each other (implementation of the step (A)). Then, at least two longitudinal sections 56 (in the example of the FIGS. 4B, 4C, 5B and 5C: six longitudinal sections 56) each having two longitudinal side faces 58, are sawn out of the plate-shaped block (implementation of the step (B)). The longitudinal side faces 58 form either an acute angle 60 (as is shown in FIG. 4A), or a right angle 60 (as is shown in FIG. 5A) with respect to one of the plate surfaces 54.

    [0114] In the case that the longitudinal side faces 58 form an acute angle 60 with respect to one of the plate surfaces 54, as is shown in FIG. 4A, the two mutually opposite longitudinal side faces 58 of a longitudinal section 56 are formed mutually inclined to one another. This enables, that the respective two longitudinal sections 56 may be mitred (or arranged mutually adjoining in a mitred way). Accordingly and as shown in the FIG. 4B, three or more longitudinal sections 56 of the FIG. 4A are put together to form a hollow body (implementation of the step (C)), such that the plate surfaces 54 of the longitudinal sections 56 form the inner wall surface 16 of a sheath section 26 of a liquid container. Then, the hollow body obtained by putting together the longitudinal sections 56 is embedded or overmoulded with concrete 66 or with a castable and/or mouldable, curable artificial stone, such that an outer sheath face (or mantle face) 62 of the hollow body is covered entirely with concrete and/or with curable artificial stone, as is indicated in FIG. 4B, and the concrete 66 or the artificial stone is let to cure (or harden) (implementation of the step (D)). In this manner, a mantle section 26 is produced, as is shown in FIG. 4C, the outer mantle face 64 of which is covered entirely with cured concrete 66 or artificial stone, and which inner wall surface 16 is formed substantially entirely as a surface of a solid natural stone 18, here in the form of the plate surfaces 54 of the longitudinal sections 56 of solid natural stone 18 provided according to FIG. 4A.

    [0115] In the case that the longitudinal side faces 58 form a right angle 60 with respect to one of the plate surfaces 54, as is shown in FIG. 5A, the two opposite longitudinal side faces 58 of a longitudinal section 56 are formed parallel to each other. In this case it is not possible to mitre (or arranged in a mitredly adjoining manner) two longitudinal sections 56 (when forming a hollow body), however respective two longitudinal sections 56 may be arranged such that the longitudinal edges of two neighbouring longitudinal sections 56, which longitudinal edges are formed each between a plate surface 54 and a longitudinal side face 58 of a longitudinal section 56, may come in contact with each other. Accordingly and as shown in FIG. 5B, three or more longitudinal sections 56 of the FIG. 5A are put together to form a hollow body (implementation of the step (C)), such that the plate surfaces 54 of the longitudinal sections 56 form the inner wall surface 16 of a sheath section 26 of a liquid container. Then, the hollow body obtained by putting together the longitudinal sections 56 is embedded in, or overmoulded by, concrete 66 or by a castable and/or mouldable, curable artificial stone, such that an outer mantle face 62 of the hollow body is covered entirely with concrete and/or the curable artificial stone, as is indicated in FIG. 5B, and then the concrete 66 or the artificial stone is led to cure (or harden) (implementation of the step (D)). In this manner, a sheath section 26 is manufactured, as is shown in FIG. 5C, the outer mantle face 64 of which is covered entirely with cured concrete 66 or artificial stone, and the inner wall surface 16 of which is formed substantially entirely as a surface of a solid natural stone 18, here as the plate surfaces 54 of the longitudinal sections 56 of solid natural stone 18 provided according to FIG. 5A.

    [0116] In order to finish a liquid container according to the one shown in FIG. 2B on the basis of a sheath section 26 manufactured according to the FIGS. 4A to 4C or according to the FIGS. 5A to 5C, there is further provided a bottom section 22 that is formed as a bottom plate (e.g. as in FIG. 2A), of which at least one side provided (or conceived) as the inner wall surface is formed substantially entirely as the surface of a solid natural stone (implementation of the step (E)). Such a bottom section 22 is connected in a liquid-tight way with an end section of the sheath section 26 shown in FIG. 4C or FIG. 5C, as is shown in FIG. 2B, such that a container 12 that is open at the other end section of the sheath section 26 is produced (implementation of the step (F)).

    [0117] The FIGS. 6A to 6D illustrate variations of the design (compare FIG. 4A, step (A)) and arrangement (compare FIG. 4B, step (B)) of longitudinal sections 56 produced according to FIG. 4A, in which an acute angle 60 is formed respectively between a plate surface 54 and a longitudinal side face 58, such that two neighbouring longitudinal sections 56 can be mitred (or arranged adjoiningly in a mitred way) one against the other.

    [0118] In FIG. 6A, three longitudinal sections 56 are mitred along their longitudinal side faces 58, so that these sections surround (define) a hollow space, which can become an inner space of a sheath section of a container 12 after embedding or overmoulding with concrete or a curable artificial stone (compare FIG. 4B, step (C)). In FIG. 6B there are provided four, in FIG. 6C six and in FIG. 6D eight longitudinal sections 56, which are respectively mitred along their longitudinal side faces 58, so that these sections surround (define) a hollow body, that can form the inner wall surface 16 of a sheath section 26 of a liquid container, as illustrated in FIG. 4C.

    [0119] The FIGS. 7A to 7D illustrate variations of the design (compare FIG. 5A, step (A)) and arrangement (compare FIG. 5B, step (B)) of longitudinal sections 56 produced according to FIG. 5A. In these longitudinal sections 56, a right angle 60 is formed respectively between a plate surface 54 and a longitudinal side face 58. In this way, respective two neighbouring longitudinal sections 56 may be arranged relative to each other such that their longitudinal edges are in contact with each other.

    [0120] In FIG. 7A there are arranged three longitudinal sections 56 respectively with their longitudinal edges in contact with each other, so that these sections surround (define) a hollow space, which may become an inner space of a sheath section 26 of a container 12 after embedding in or overmoulding with concrete or a curable artificial stone (compare FIG. 5B, step (C)). In FIG. 7B there are provided four, in FIG. 7C six and in FIG. 7D eight longitudinal sections 56, respectively in contact with each other along their longitudinal edges, so that these sections surround (define) a hollow body, that may form the inner wall surface 16 of a sheath section 26 of a liquid container, as illustrated in FIG. 5C.

    [0121] The arrangements of longitudinal sections 56 produced from solid natural stone as shown in the FIGS. 4B, 5B, 6A to 6D and 7A to 7D illustrate, that the inner wall surface 16 of a sheath section 26 of a container 12 can be subdivided in a circumferential direction in plural (two or more) segments, for example three segments (as in FIGS. 6A and 7A), in four segments (as in FIGS. 6B and 7B), in six segments (as in FIGS. 6C and 7C) or in eight segments (as in FIGS. 6D and 7D). However, the number of the segments mutually aligned (or arranged) in the circumferential direction can also be two, five, seven or any larger integer.

    [0122] It should be noted, that a sheath section 26 of a container 12 may not only be subdivided into plural (two or more) sheath segments in its circumferential direction, but also in its longitudinal direction, for example axial direction, as is illustrated by way of example in FIG. 11. FIG. 11 shows schematically a sheath section 26 for a container according to the invention, that is put together of three sheath segments 34 according to the invention.

    [0123] FIG. 8 shows schematically a sheath section 26 according to the invention for a liquid container according to the invention, which is to be seen as a variation of the embodiment of the sheath section 26 shown in FIG. 5B. In the sheath section 26 shown in FIG. 8, instead of the longitudinal sections of solid natural stone 18 shown in FIG. 5B, there are composite bodies overmoulded with concrete 66. Each of the composite bodies shown in FIG. 8 consists of a bearing layer 28 that does not consist of natural stone (or solid natural stone), and a covering layer 30 respectively a covering layer segment 32, which is formed of solid natural stone 18 and is two-dimensionally connected with the bearing layer 28. These composite bodies may be provided in shapes that correspond to the variable different possible shapes of the longitudinal sections 56 illustrated in the FIGS. 6A to 7D, and containers 12 according to the invention can be produced from these (composite bodies).

    [0124] FIG. 9 shows schematically a sheath section 28 according to the invention for a liquid container according to the invention, which is to be seen as a variation of the embodiment of a sheath section 26 made of solid natural stone and shown in FIG. 2B. In the sheath section 26 shown in FIG. 9, instead of the relatively thick sheath section of solid natural stone shown in FIG. 2B, a tubular (or cylinder-shaped) body (mono block) of natural stone, though having a relatively smaller thickness, is provided, and is overmoulded with concrete 66 or a curable artificial stone.

    [0125] With reference to the FIGS. 4B and 5B it has been described that an arrangement of plural longitudinal sections 56 defining a hollow body can be overmoulded by (or embedded in) concrete 66 or a mouldable and curable artificial stone. In a variation of this method step, it is also possible to provide a, e.g. tubular, body that has been moulded of concrete or a curable artificial stone as a bearing layer 28 and to fix, for example glue (or stick) on their inner surface, a plurality of longitudinal sections 56 consisting of solid natural stone or, alternatively, also plates, e.g. rectangular plates, such as tiles, that are subdivided in the longitudinal direction (axial direction) in smaller segments and have a surface of solid natural stone as a covering layer 30. In this variational embodiment, the, e.g. rectangular, plates, such as tiles, form covering layer segments 32 of a covering layer 30 consisting of solid natural stone, which segments are fixed to an inner surface of a bearing layer 28 that does not necessarily has to be of natural stone, such that an inner wall surface is subdivided in covering layer segments 32, though substantially entirely formed of solid natural stone.

    [0126] A liquid container 10, such as it has been described hereinbefore, may be used in a method for producing and/or storing of liquids to be provided for drinking consumption. The basic requirements for such a container 12 comprise that the container 12 is open on one side, that it comprises a container wall 14 having an inner wall surface 16, and that the inner wall surface 16 is formed at least partially as a surface of a solid natural stone 18.

    [0127] According to the method according to the invention for the production and/or storage of a liquid provided for drinking consumption or of a pre-product for such a liquid, initially a liquid container 10 is provided, which satisfies the basic requirements mentioned in the preceding paragraph (step (i)). Then, at least a partial section of the liquid container 10 is cooled down with respect to the temperature of the surrounding air atmosphere (step (ii)). Thereafter, a liquid is filled into the liquid container 10 that has been cooled down (step (iii)). Finally, a step of a chemical and/or biochemical conversion of the liquid that has been filled in is initiated, such as a fermentation or a conversion of sugar to alcohol, so as to generate the liquid or a pre-product for it (step (iv)). During the chemical and/or biochemical conversion, no further measure (or process) for cooling the liquid container 10 and/or the liquid residing in the liquid container 10 is taken (or performed).

    [0128] The cooling down in step (ii) may be achieved automatically in the context (or course) of a temperature equilibration in a room (or environment) that is blocked from sunlight and heat irradiation. A suitable room may be at least partially situated under the surface of the earth. In the production of wine, a wine cellar may be a suitable room. The cooling down may occur to (or into) the temperature range of from 6 C. to 12 C., preferably to the temperature range of from 8 C. to 10 C.

    [0129] The liquid container 10 may comprises a sheath section 26 and a bottom section 22, and the cooling down may comprise a cooling down of at least a partial section of the sheath section 26 and the bottom section 22. The liquid container 10 may further comprise a lid 36, and the cooling down may comprise a cooling down of at least a partial section of the lid 36.

    [0130] In the method according to the invention, subsequent to the steps (i) to (iv) mentioned above, in the liquid container 10, further conditioning and/or treatment steps may be initiated, performed and/or awaited for/with a pre-product obtained in step (iv), such as a maturing process, by which the liquid to be provided for drinking consumption is finally generated.

    [0131] The liquid may an alcohol-containing liquid, such as wine, fruit wine, or another beverage that can be made from the juice of grapes or fruits, or schnapps, whisky, beer, or a mixed beverage.

    [0132] It should be noted that the term comprising does not exclude other elements or steps and the article a or an does not exclude a plurality. Also, elements described in association with different embodiments may be combined.
