Container for the storage and/or fermentation of alcoholic beverages

Abstract

A container for food liquids, in particular for the storage and/or fermentation of alcoholic beverages, has a body in which a substantial portion of the walls of the container is made of a ceramic material with controlled porosity. The body of the container is shaped as a truncated pyramid, in which each of the faces of the side wall includes a slab of ceramic material with controlled porosity, and in which a support structure made of cementitious material is formed along the external corners of the side wall and in correspondence with the bases of the truncated pyramid. Axial openings are defined in the bases of the container and are adapted to cooperate with suitable closing members.

Description

[0024] Further advantages and characteristics of the container according to the present invention will become evident from the description of an embodiment of the same yield, by way of non-limiting example, with reference to the attached drawings, in which:

[0025] FIG. 1 is a side elevated view of an embodiment of the container according to the present invention;

[0026] FIG. 2 is a cross-sectional view along the line II-II of FIG. 1;

[0027] FIG. 3 is a top plan view of the container of FIG. 1;

[0028] FIG. 4 is a longitudinal section view along the line IV-IV of FIG. 3; and

[0029] FIG. 5 is a perspective view with exploded parts of the container of FIG. 1.

[0030] FIG. 6 illustrates a perspective view of an embodiment variant of the container according to the present invention.

[0031] FIG. 1 illustrates an embodiment of the container according to the present invention; 1 indicates the body of said container, comprising a plurality of slabs 101 assembled to form the side wall of a regular octagonal pyramid trunk, said side wall being surrounded by a support structure comprising the uprights 201, located at the corners of the lateral wall, the major base 401 and the minor base 301, in which the closing means 2 are positioned.

[0032] In FIG. 2 the container of FIG. 1 is sectioned along the line II-II; equal parts correspond to equal numerals. The figure shows the positioning of the closing means 3 arranged in the opening 411 formed in the larger base 401. Furthermore, it is evident that the different slabs 101 are arranged consecutive to each other.

[0033] FIGS. 3 and 4, in which the same parts correspond to the same numerals, allow the most complete structural view of the container according to the present invention, as well as the exploded perspective of FIG. 5, which allows to view the fundamental components of the container, i.e. the wall side facing inwards, consisting of the slabs 101 in ceramic material with controlled porosity, the support structure in cementitious material, consisting of the uprights 201 and the bases 301 and 401, and the closing means 2 and 3 in steel, located in the respective openings 311 and 411 of the bases 301 and 401.

[0034] As is evident from the figures, said uprights 201, the elements of the minor base and of the major base 301, 401 of the support structure, form a sort of frame which overlaps with said uprights 201 and with said bases 301, 410 to a peripheral band of the surface of the side of the base 301 facing the outside of the container, leaving free and directly accessible from the external environment an area of considerably greater size in the central area of each slab 101.

[0035] In essence, the supporting structure forms a sort of peripheral frame for the slabs since all the frames are joined together in one piece in the supporting frame common to all the slabs 101.

[0036] Different embodiments are possible as shown in the examples of FIGS. 5 and 6.

[0037] In FIG. 6 the upper cover 2 is provided with a cap 20 which closes the central opening of the same and which can be opened, i.e. separable from the cover 2 as shown in the figures of the previous example in which said cap is missing

[0038] It is clear that by changing the ratio between the area of the surface of the external side covered by the load-bearing structure and the area of said surface directly exposed to the external environment, it is possible to calibrate the permeability characteristics of the casing wall of the container even in the presence of sheets of permeable material controlled and constant for each slab.

[0039] Different variants are possible which provide that all or only some of said slabs have a central part of a predominant area directly exposed to the external environment, that is, not covered by the load-bearing structure.

[0040] In this case, some or all of the sheets may have a different degree of coverage of the surface of the external side of the same with the material of the supporting structure.

[0041] Alternatively or in combination, some slabs can also be completely covered by the material of the supporting structure.

[0042] The variants described above therefore make it possible to always use the same type of sheet and to calibrate the overall permeability of the container wall according to the specific use by operating on the ratio between the covered surface and the uncovered surface and directly exposed to the environment.

[0043] The aspect of the art will understand that this type of calibration can easily take place during manufacturing and thanks to an experimental process in relation to a specific type of product and possibly also to the environmental conditions in which the containers are intended to operate.

[0044] Generally, but not limitatively for oenological products, the percentage of the surface of each slab is directly exposed to the external environment, which is not covered by the supporting structure is between 70 and 95% of the total area of the outer side surface of the same

[0045] Operation and the construction of the container according to the present invention will appear evident from the following. With reference to the known art document WO2018163026 cited in the introduction, it was considered, in the course of the research that led to the present invention, that the production of molds for large-sized products, such as the components for the construction of a container for the fermentation and/or storage of alcoholic beverages, can lead to criticalities in the production of the ceramic material with controlled porosity, at the risk of effectively compromising the enjoyment of its peculiar characteristics; one of the effects found is that the material, during the drying and subsequent sintering phase, undergoes changes in state that can generate structural criticalities due to the larger dimensions and therefore the high weight of the product itself.

[0046] The container according to the present invention allows to realize the ceramic material in an extremely controlled way, starting from the formation of large slabs which are then shaped in the most appropriate way and assembled using adhesive materials suitable for food use. The determination of the number of faces of the side wall, i.e. the number of sides of the bases, is a fair compromise between a reasonably low number of sections and a container shape as rounded as possible, in order to make the movements of the liquid more homogeneous inside it. In the illustrated embodiment, the regular truncated pyramid has eight faces on its side wall.

[0047] The slabs which are shaped on the basis of the initial project are then joined together and inserted into a mold, preferably together with the closing means of the bases, that is, suitably formed steel slabs on which doors or manhole covers can be subsequently mounted.

[0048] The container according to the present invention therefore has most of the surface in contact with the alcoholic beverage endowed with the peculiarities of a ceramic material with controlled porosity, and exhibits constructive specificities that make it extremely interesting in the panorama of the sector.

[0049] It is worth remembering that particularly with regard to fermentation processes in general, and in particular the winemaking processes, including those relating to the conservation and/or aging of the product, these processes are extremely delicate. Therefore, the use of materials that directly promote the natural mechanisms of the process avoids plant complications and also the acquisition and maintenance costs of the same, which strongly affect the profitability of production especially for medium and small wineries.

[0050] The invention allows the processes to be kept naturally regulated with a simple container which operates on the basis of natural principles and which avoids high purchase and maintenance costs.
