Description

"External device for detecting sulfites in the contents of a bottle"
Description Field of the art
The present invention operates in the field of enology, with particular reference to the consumer's right to be informed. More in detail, the present invention regards a new and innovative label for wine bottles, adapted to indicate the presence of sulfites in the wine to the consumer.
Prior art
Several years ago, EU regulations introduced the obligation of indicating sulfites on labels; however, according to current rules, if the total sulfites are present in the wine in a quantity equal to or lower than 10 mg/liter, they are not considered to be capable of causing allergies or intolerances and hence their presence does not have be indicated on labels.
On this matter, those working in the industry have often lamented the fact that they only receive partial information, which does not allow indicating a range of information that is not currently expressly regulated at the EU Community level - such as the absence of sulfites, the presence of sulfites (when below the threshold limit of 10 mg/liter) and the information relative to the non-use of sulfites in the course of the wine-making process.
The European Commission states that the indication on the label "without added sulfites" is allowed if the wine contains only sulfites obtained naturally in the course of the fermentation, in a quantity that, in any case, must not exceed 10 mg/liter in terms of total S02.
In other words, if the concentration of S02 is equal to 15 mg/liter, this does not have to be indicated on the label if the sulfites present in the wine were not added, but rather were instead endogenous, i.e. synthesized by the wine yeast during fermentation.
Indeed, in some cases, such information coexists with the writing 'contains sulfites', which may be contradictory in the eyes of the consumer, but in any case is representative of the factual reality. In other words, this means: a content greater than 10 mg/liter of total sulfur dioxide is present, not added, but synthesized by the wine yeast during the alcoholic fermentation.
As is obvious, consumer protection prevails with respect to the indication "without added sulfites" on a label, also when the sulfites (even if often in minimal amounts) are in any case present in the wine.
Today, two white wines report on the label the same indication "contains sulfites" even when one has a total content of S02 equal to 15 mg/liter and the other a total content of 190 mg/liter, the latter a concentration that exceeds the maximum threshold allowed by EU regulations.
Indeed, for this reason there are those who sustain and deem necessary the insertion of detailed analytical information on the label, i.e. the actual content of sulfur dioxide (at the time of bottling), which in such case could and should be separated into two fractions: free and total.
On such matter, Reg. (EU) 1169/2011 does not obligate wine bottlers to affix the list of ingredients on labels ("ingredient" also indicating additives such as S02 and any other substance used in the production process but still present in the finished product, even if in modified form), but from a certain standpoint clearly-indicated S02 information could become an instrument for stimulating good agronomic and cellar practices, encouraging a reduction of the use of sulfites where technologically possible.
The labels of eno-gastronomic products are also the object of various international patents, e.g. the French patent FR 29 77 051 which describes a method for creating a series of holograms on labels in order to form authentication labels, by associating a signature with each of the labels affixed on the products.
Apart from the obligations regarding product transparency and label indications, there is no instrument in the state of the art that allows the consumer to obtain more precise information regarding the product the he/she is consuming, in particular regarding the concentration of sulfites.
Object of the present invention is, therefore, that of proposing a new and innovative type of label that reveals, independent of that stated by the producer, the actual composition of the wine and the concentration of sulfites present therein.
Description of the invention
According to the present invention, an external device is attained for detecting sulfites in a bottle.
It has considerable advantages, above all in relation to the fact that currently there is no device that is sold together with the bottle and which acts as a quality guarantee, allowing the user to verify the concentration of sulfites in the contents of the bottle.
The use of the device described hereinbelow is particularly advantageous for application to wine bottles.
For this purpose, it is possible to use the present invention in two versions: as a device sold already attached to the bottle, or as a kit for a plurality of devices which the user purchases and uses for testing the presence of sulfites in the contents of the bottles that he/she has selected.
Substantially, this is an adhesive strip adapted to be attached to the bottle at the neck. In this manner, the case is advantageously avoided in which - by placing the bottle in an ice bucket - the device becomes wet and loses its effectiveness.
Versions are in any case allowed in which the present device is made to adhere vertically on the bottle, i.e. in a configuration parallel to the longitudinal axis of the bottle itself. A preferred version, in order to avoid the risk of wetting the device, provides that at least the outermost surface of the latter is impermeable.
The device consists of at least two elements:
A) a tape provided with an adhesive internal surface, adapted to stably adhere to the neck of the bottle and with an external surface provided with a key. The latter is advantageously adapted to reveal the code according to which the result of the sulfites analysis is to be interpreted, such analysis occurring on the other component of the device.
B) a litmus paper constituted by a small strip of absorbent paper soaked with a litmus solution adapted to detect the presence, the concentration and the composition of sulfites in the contents of the bottle. More in detail, the litmus paper is advantageously provided with an external surface with a grip tongue in order to allow the user to grasp it and remove it from the neck of the bottle. The other surface, i.e. the internal surface, is adhesive and is initially placed adherent to the external surface of the tape. After the removal of the litmus paper, this must be slightly wet with the contents of the bottle in order to ensure that a plurality of colored bars appear at least on the internal surface of the litmus paper, due to the chemical reaction that occurs between the litmus solution and the sulfites present in the drink. Advantageously, the user can interpret the result of such detection by comparing the colored bars that appear on the litmus paper with the key placed on the external surface of the tape.
Possibly, the external surface of the litmus paper can advantageously report the identification data of the company producing the external device for detecting sulfites, as a guarantee of its authenticity.
Advantageously, the internal surface of the litmus paper, i.e. that where the result of the sulfites test appears, can be made of a phosphorescent material so to make the test result visible even if the setting is poorly lit.
Another very important characteristic for the tasting of many drinks, and of wine in particular, is its temperature. For this reason, in one version of the present invention, said external device for detecting sulfites can be advantageously adapted to change color as a function of the temperature of the contents of said bottle, when placed in contact with such contents.
Advantageously, the external surface of said litmus paper can also be adapted to indicate the excessive concentration of sulfites and/or an overly high or overly low service temperature for the wine (or other drink) simply by changing color. In this case, of course, a key of these colors will also be reported on the external surface of the tape, in order to allow the user to interpret the meaning thereof.
Finally, a preferred embodiment of the present invention provides for attaining the device in three layers, rather than two layers as has been described up to now.
The third layer is an external layer that has the internal surface adhesive and the external surface that reports the data of the producer of the bottle contents. Said external layer is first attached at the external surface of said litmus paper. The mode of use consists of detaching the three layers constituting the device and gluing them in a column-like manner on the neck of the bottle. In such a manner, the following will be readily visible for the consumer: the producer, the key for interpreting the colored bars and possibly the colors of the litmus paper, and the litmus paper itself, with the result of the sulfites test made visible from the outside even without seeing the bottle label.
The advantages offered by the present invention are evident in light of the description set forth up to now and they will be even clearer due to the enclosed figures and to the relative detailed description.
Description of the figures
The invention will now be described in at least one preferred embodiment as a non-limiting example with the aid of the enclosed figures, in which:
- FIGURE 1 shows a common wine bottle 100, the litmus paper 10 of the present invention attached to the neck 101 thereof; the external surface 10.1 of such litmus paper 10 is seen with the grip tongue 11.
- FIGURE 2 illustrates the bottle 100 from which the litmus paper 10 has been removed; the external surface 10. a is seen with the grip tongue 11, and the internal surface 10.2 is seen as well. Regarding the tape 12, remaining on the neck 101 of the bottle 100, the external surface 12.1 is seen with the colored bars 13 which indicate the result of the sulfites test.
- FIGURE 3 shows a version with more accessories, in which, after having performed the sulfites test, the external layer 15, with the external surface 15.1 directed outward, the tape 12, with the external surface 12.1 directed outward and the litmus paper 10, with the internal surface 10.2 directed outward are attached to the neck 101 of the bottle 100.
Detailed description of the invention
The present invention will now be illustrated as a merely exemplifying and non-limiting or non-binding example, making use of the figures which illustrate several embodiments relative to the present inventive concept.
With reference to FIG. 1, a view of a common bottle 100 is illustrated, e.g. a wine bottle; the present device is attached to the neck 101 thereof, such device appearing as a simple adhesive strip. Externally, a litmus paper 10 is placed, on whose external surface 10.1 the data of the company producing the device can be reported, as a confirmation of its authenticity. It is seen that said litmus paper 10 is provided with a grip tongue 1 1, due to which a user can detach it from said bottle 100, to which such paper adheres due to the adhesive internal surface 10.2, revealing the operation thereof (FIG. 2).
Said litmus paper 10 is constituted by a common strip of absorbent paper soaked with a litmus solution that chemically reacts with the sulfites. Once detached from the bottle 100, it is sufficient to slightly wet it with the contents of the bottle 100 in order to make, at least on the internal surface 10.2 thereof, a plurality of colored bars 13 appear which graphically depict the presence, the concentration and the composition of the sulfites, according to a pre- established code.
Said code is represented on the second element of the device, object of the present invention, i.e. on the tape 12. This remains attached to the neck 101 of the bottle 100 due to its adhesive internal surface. On the external surface 12.1, a key 14 is represented which allows interpreting the colored bars 13 that appear on the internal surface 10.2 of the litmus paper 10 when this is placed in contact with the contents of the bottle 10.
With reference to FIG. 3, a more complete version is shown of the device with more accessories; in this case, the device constituted by three elements. In addition to the tape 12 and the litmus paper 10, also an external layer 15 is present, provided with a reversibly adhesive internal surface and with an external surface bearing the data of the company producing the contents of the bottle 100. Initially, the device is presented in a first closed configuration in which the litmus paper 10 is glued on top of the tape 12 and the external layer 15 is superimposed on the litmus paper 10.
Once the bottle 100 is open, the device is placed in a second open configuration in which it is possible to view the name of the wine (or other drink) and data of the producer, the key 14 of the sulfites analysis and the result of the sulfites analysis. More in detail, first the external layer 15 is removed and it is attached, due to the reversibly adhesive internal surface, on the neck 101 of the bottle 100 in a position different from that of the tape 12. Subsequently, the litmus paper 10 is detached and the sulfites test is executed, by wetting it with the contents of the bottle 100. Once the colored bars 13 have appeared, said litmus paper 10 is attached to the neck of the bottle 100 with the internal surface 10.2, reporting the colored bars 13, facing outward. This is possible due to the fact that in this version of the invention, the external surface 10.1 of the litmus paper 10 is also reversibly adhesive. By attaching the litmus paper 10 in a position different from that of said tape 12, but always on the neck 101 of the bottle 100, it is possible to see all the pertinent data of the drink that is being consumed even without seeing the label, e.g. when the bottle 100 is placed in an ice bucket.
A further embodiment of the device provides for the change of color of one of the two surfaces 10.1-10.2 of the litmus paper 10, not only in the case of exceeding a predetermined sulfites concentration but also based on the temperature of the drink. In this case, the external surface 12.1 of the tape 12, on which the key 14 is reported for the interpretation of the colored bars 13, will also include the key for interpreting the color of the litmus paper 10. It should be specified that the representation, in the figures, of the present device arranged as a circle around the neck 101 of the bottle 100 only represents the preferred position that prevents the litmus paper 10 from becoming wet when the bottle 100 is placed in an ice bucket. This is not to be considered limiting for the attainment of devices to be arranged parallel to the longitudinal axis of the bottle 100.
Other possible embodiments of the external device for detecting sulfites in the contents of a bottle 100 can provide for making the external surface 10.1 of the litmus paper 10 impermeable and/or for making at least the internal surface 10.2 of the litmus paper 10 of a phosphorescent material, in a manner so as to render visible the possible colored bars 13 even in a poorly lit setting.
In conclusion, it is clear that the devices, object of the present patent, can be sold both simultaneously with the bottle and separately, in prepackaged kits containing a plurality of devices.
Finally, it is clear that modifications, additions or variations that are obvious for a man skilled in the art can be made to the invention described up to now, without departing from the protective scope that is provided by the enclosed claims.
