“SACCO PER IL CONTENIMENTO DI PRODOTTI LIQUIDI DEGASANTI, IN PARTICOLARE LIEVITO†⠀ œSACK FOR CONTAINING LIQUID DEGASANTS, IN PARTICULAR YEASTâ €
DESCRIZIONE DESCRIPTION
La presente invenzione ha per oggetto un sacco per il contenimento di prodotti liquidi che emanano gas, in particolare lieviti per panificazione. The present invention relates to a bag for containing liquid products that give off gas, in particular yeast for bread making.
Nella descrizione che segue si farà specifico riferimento al lievito, ma à ̈ da intendersi che l’invenzione à ̈ applicabile a qualsiasi prodotto liquido o pastoso che in fase di stoccaggio emana gas. In the following description specific reference will be made to yeast, but it is to be understood that the invention is applicable to any liquid or pasty product which gives off gas during storage.
Il lievito, nella fase di produzione, à ̈ sempre allo stato liquido e, per l’immissione sul mercato, nella maggior parte dei casi, viene successivamente disidratato per trasformarlo in polvere o in forma di panetti solidi. In fase di utilizzazione il lievito deve nuovamente essere riportato alla forma liquida. The yeast, in the production phase, is always in a liquid state and, for the placing on the market, in most cases, it is subsequently dehydrated to transform it into powder or in the form of solid blocks. During use, the yeast must again be brought back to its liquid form.
Negli ultimi tempi c’à ̈ la tendenza a produrre e confezionare il lievito direttamente in forma liquida, cosa che risulta vantaggiosa dai punti di vista pratico ed economico, in quanto vengono eliminati i passaggi di trasformazione dallo stato liquido allo stato solido in fase di produzione e viceversa in fase di utilizzazione. In recent times there has been a tendency to produce and package yeast directly in liquid form, which is advantageous from a practical and economic point of view, as the transformation steps from the liquid state to the solid state are eliminated. production and vice versa during use.
Il problema nello stoccaggio del lievito liquido à ̈ che esso emana una notevole quantità di gas, in particolare CO2, fino a 1-3 litri al giorno per una confezione da 10/20 litri. The problem in the storage of liquid yeast is that it gives off a considerable amount of gas, in particular CO2, up to 1-3 liters per day for a 10/20 liter pack.
Sono quindi necessari sacchi che da un lato siano altamente permeabili ai gas, e dall’altro abbiano un’adeguata tenacità per sostenere il peso del contenuto, avendo tali sacchi normalmente una capacità di 10/20 litri. Therefore, bags are required that on the one hand are highly permeable to gases, and on the other hand have an adequate toughness to support the weight of the content, as these bags normally have a capacity of 10/20 liters.
Per soddisfare tali esigenze sono stati quindi proposti sacchi a “doppia parete†presentanti cioà ̈ un film interno altamente permeabile alla C02 a base di polietilene, di spessore molto sottile (30-50 pm) e quindi poco resistente meccanicamente, e un film esterno costituito da un laminato a base di nylon, dello spessore di 80-150 pm, atto a conferire la necessaria resistenza meccanica al sacco. To meet these needs, `` double-wall '' bags have therefore been proposed, presenting an internal film highly permeable to C02 based on polyethylene, with a very thin thickness (30-50 pm) and therefore not very resistant mechanically, and an external film consisting of a nylon-based laminate, 80-150 pm thick, designed to give the necessary mechanical resistance to the bag.
Il film esterno, che non à ̈ permeabile, presenta una pluralità di piccoli fori per consentire la fuoriuscita dei gas che permeano attraverso il film interno. The external film, which is not permeable, has a plurality of small holes to allow the escape of the gases that permeate through the internal film.
Il sacco così conformato viene disposto all’interno di una scatola di cartone, in modo da costituire una confezione cosiddetta “bag-in-box†che sia facilmente manipolabile. The bag thus shaped is placed inside a cardboard box, so as to form a so-called â € œbag-in-boxâ € package that is easily manipulated.
I sacchi del tipo suddetto non si sono dimostrati soddisfacenti, in quanto, nonostante la previsione del film esterno forato, si à ̈ constatata una non soddisfacente fuoriuscita dei gas che tendono a gonfiare il sacco. Bags of the aforesaid type have not proved to be satisfactory, since, despite the provision of the perforated outer film, an unsatisfactory escape of the gases which tend to inflate the bag has been found.
Ciò à ̈ dovuto al fatto che quando il sacco riempito di lievito liquido viene inserito nella scatola di cartone, esso si conforma alla scatola determinando un contatto a pressione tra la superficie esterna del sacco e le pareti interne della scatola, a parte lo spazio di testa del sacco che rimane libero. This is due to the fact that when the bag filled with liquid yeast is placed in the cardboard box, it conforms to the box causing a pressure contact between the external surface of the bag and the internal walls of the box, apart from the headspace. of the bag that remains free.
Tale contatto a pressione determina una forte aderenza tra i film plastici interno ed esterno del sacco, occludendo praticamente i fori previsti nel film esterno ed impedendo quindi la fuoriuscita dei gas, che tendono ad accumularsi nella parte superiore del sacco, dove faticano a fuoriuscire causa la scarsa superficie forata del film esterno non a contatto con la parete interna della scatola di contenimento. This pressure contact determines a strong adhesion between the internal and external plastic films of the bag, practically occluding the holes provided in the external film and thus preventing the escape of gases, which tend to accumulate in the upper part of the bag, where they struggle to escape due to the scarce perforated surface of the external film not in contact with the internal wall of the containment box.
Scopo dell’invenzione à ̈ quello di eliminare gli inconvenienti anzidetti della tecnica nota. The purpose of the invention is to eliminate the aforementioned drawbacks of the known art.
In particolare, uno scopo dell’invenzione à ̈ quello di fornire un sacco per lieviti liquidi che consenta una completa e rapida degasazione del prodotto in esso contenuto. In particular, an object of the invention is to provide a bag for liquid yeasts which allows a complete and rapid degassing of the product contained therein.
Altro scopo dell’invenzione à ̈ quello di fornire un tale sacco che risulti di semplice ed economica realizzazione. Another purpose of the invention is to provide such a bag which is simple and inexpensive to make.
Il sacco secondo l’invenzione presenta le caratteristiche dell’annessa rivendicazione indipendente 1. The bag according to the invention has the characteristics of the attached independent claim 1.
Realizzazioni vantaggiose dell’invenzione appaiono dalle rivendicazioni dipendenti. Advantageous embodiments of the invention appear from the dependent claims.
Sostanzialmente, il sacco secondo l’invenzione, del tipo cosiddetto a doppia parete, comprende un film interno ad alta permeabilità a base di polietilene e un laminato esterno di rinforzo a base di nylon, in cui almeno nella parte superiore di ciascuna faccia del sacco, tra il film interno ed il film esterno à ̈ previsto almeno un elemento distanziatore tra tali film fissato perimetralmente ad un’apertura praticata nel film esterno e provvisto di fori per la fuoriuscita del gas. Basically, the bag according to the invention, of the so-called double-wall type, comprises an internal film with high permeability based on polyethylene and an external reinforcement laminate based on nylon, in which at least in the upper part of each face of the bag between the internal film and the external film there is at least one spacer element between these films fixed perimeter to an opening made in the external film and provided with holes for the escape of the gas.
Convenientemente, tale elemento distanziatore comprende un corpo forato avente un bordo perimetrale termosaldato a detto film esterno e una eventuale sede di alloggiamento di un coperchio o piattello anch’esso forato. Conveniently, this spacer element comprises a perforated body having a perimeter edge heat-sealed to said external film and a possible housing seat for a lid or plate which is also perforated.
Preferibilmente, il film interno del sacco à ̈ un coestruso LLDPE di 30 pm (28 g/m ), mentre il film , esterno à ̈ un laminato comprendente uno strato di OPA<1>(nylon) di 15 pm (17 g/m ), interposto tra due strati di coestruso LLDPE-EVA di 38 pm (35 g/m<2>). Preferably, the inner film of the bag is a 30 pm (28 g / m) LLDPE coextruded film, while the outer film is a laminate comprising a 15 pm (17 g / m) OPA <1> (nylon) layer. ), interposed between two coextruded layers of 38 µm LLDPE-EVA (35 g / m <2>).
Gli strati esterni a base di polietilene LLDPE (Linear Low Density Polyethylene), consentono la termosaldatura del film esterno al film interno, anch’esso a base di polietilene, nonché la termosaldatura degli elementi distanziatori al film esterno, mentre lo strato intermedio di OPA (Oriented Poly Ammide) conferisce tenacità al sacco. The external layers based on LLDPE polyethylene (Linear Low Density Polyethylene), allow the heat sealing of the external film to the internal film, also based on polyethylene, as well as the heat sealing of the spacer elements to the external film, while the intermediate layer of OPA (Oriented Poly Amide) gives the bag toughness.
Ulteriori caratteristiche dell’invenzione appariranno più chiare dalla descrizione dettagliata che segue, riferita ad una sua forma puramente esemplificativa e quindi non limitativa di realizzazione, illustrata nei disegni annessi, in cui: Further characteristics of the invention will appear clearer from the detailed description that follows, referring to a purely exemplary and therefore non-limiting embodiment, illustrated in the attached drawings, in which:
la figura 1 à ̈ una vista schematica in pianta del sacco secondo l’invenzione; la figura 2 à ̈ una vista ingrandita in sezione secondo la linea II-II di figura 1 interessante una sola faccia del sacco; figure 1 is a schematic plan view of the bag according to the invention; figure 2 is an enlarged sectional view along the line II-II of figure 1 involving only one face of the bag;
la figura 3 Ã ̈ una sezione ingrandita in misura minore rispetto alla figura 2, presa secondo la linea III-III di figura 1; Figure 3 is a section enlarged to a lesser extent than Figure 2, taken along the line III-III of Figure 1;
la figura 4 Ã ̈ una vista schematica in prospettiva del sacco di figura 1. Figure 4 is a schematic perspective view of the bag of Figure 1.
Con riferimento a tali figure, il sacco secondo l’invenzione, per il contenimento di prodotti liquidi che emanano gas, in particolare lievito, à ̈ stato indicato con il numero di riferimento 1. With reference to these figures, the bag according to the invention, for containing liquid products that give off gas, in particular yeast, has been indicated with the reference number 1.
Esso comprende due facce contrapposte 2, unite mediante una saldatura perimetrale 3, che coire parallelamente al suo bordo esterno 4. It includes two opposing faces 2, joined by a perimeter weld 3, which runs parallel to its outer edge 4.
Nelle figure annesse il sacco 1 à ̈ stato illustrato di forma rettangolare, che à ̈ quella più semplice da realizzare, ma à ̈ evidente che esso può assumere qualsiasi altra forma. In the accompanying figures, bag 1 has been shown as having a rectangular shape, which is the simplest to make, but it is evident that it can assume any other shape.
Il sacco 1 Ã ̈ del tipo cosiddetto a doppia parete, nel senso che ciascuna delle sue due facce contrapposte 2 comprende due film, uno interno 5 e uno esterno 6, separati tra loro e uniti solo in corrispondenza di detta linea di saldatura perimetrale 3. The bag 1 is of the so-called double-walled type, in the sense that each of its two opposite faces 2 comprises two films, one internal 5 and one external 6, separated from each other and joined only in correspondence with said perimeter welding line 3.
Su una delle due facce 2 del sacco 1 à ̈ applicato un bocchello 7 di riempimento/erogazione del prodotto, presentante una flangia circolare di base 8 saldata internamente alla corrispondente faccia 2, mentre il bocchello 7 sporge attraverso un foro praticato in tale faccia, ed à ̈ chiuso da un tappo 20. On one of the two faces 2 of the bag 1 a product filling / dispensing nozzle 7 is applied, presenting a circular base flange 8 welded internally to the corresponding face 2, while the nozzle 7 protrudes through a hole made in this face, and It is closed by a cap 20.
Il film interno 5 della doppia parete del sacco à ̈ ad alta permeabilità ai gas, in particolare alla C02 che viene prodotta in grande quantità dal lievito contenuto nel sacco, > di 50 l/m<2>giorno atm. Esso à ̈ a base di polietilene, ad esempio un coestruso LLDPE ed ha uno spessore molto sottile (30 pm) per poter ottenere i suddetti alti valori di permeabilità . The internal film 5 of the double wall of the bag has a high permeability to gases, in particular to C02 which is produced in large quantities by the yeast contained in the bag,> 50 l / m <2> day atm. It is based on polyethylene, for example a coextruded LLDPE and has a very thin thickness (30 pm) in order to obtain the aforementioned high permeability values.
Un tale film sarebbe da solo molto fragile e quindi soggetto a facili lacerazioni. Such a film alone would be very fragile and therefore subject to easy tearing.
Pertanto, al film esterno 6 à ̈ assegnato il compito di conferire tenacità al sacco ed evitare facili rotture. Therefore, the external film 6 is assigned the task of giving toughness to the bag and avoiding easy breakages.
Tale film esterno 6 à ̈ normalmente un laminato a più strati, ad esempio comprendente: This external film 6 is normally a multilayer laminate, for example comprising:
- un primo strato di 38 pm di coestruso LLDPE-EVA da 35 g/m ; - a first layer of 38 µm of 35 g / m LLDPE-EVA coextruded;
- un secondo strato di 15 Î1⁄4ηι di ΟΡΑ (nylon) da 17 g/m ; - a second layer of 15 Î1⁄4Î · ι of ΟΡΠ‘(nylon) of 17 g / m;
- un terzo strato di 38 Î1⁄4ηι di coestruso LLDPE-EVA da 35 g/m . - a third layer of 38 Î1⁄4Î · ι of 35 g / m LLDPE-EVA coextruded.
Naturalmente il numero degli strati del laminato costituente il film esterno 6 può essere differente rispetto a quello illustrato, purché contenenti uno strato ad alta tenacità , quale lo strato di OPA (nylon) e almeno uno strato esterno a base di polietilene, per consentire l’esecuzione della saldatura perimetrale 3, nonché la saldatura della base 8 del bocchello 7, e la saldatura di elementi distanziatori 10 tra i film interno 5 ed esterno 6 di ciascuna faccia 2 del sacco 1, come sarà ora meglio descritto. Naturally, the number of layers of the laminate constituting the outer film 6 may be different from that illustrated, provided they contain a high tenacity layer, such as the OPA layer (nylon) and at least one outer layer based on polyethylene, to allow the Execution of the perimeter welding 3, as well as the welding of the base 8 of the nozzle 7, and the welding of spacer elements 10 between the internal 5 and external 6 films of each face 2 of the bag 1, as will now be better described.
Infatti, ad evitare che i due film aderiscano tra loro quando il sacco 1 viene inserito in una scatola di contenimento (bag-in-box) normalmente di cartone, almeno nella parte superiore di ciascuna faccia 2 del sacco, sostanzialmente a livello del bocchello di erogazione 8, à ̈ disposto un elemento distanziatore 10 che da un lato consente di tenere distanziati i film 5 e 6 della corrispondente faccia 2 e dall’altro la fuoriuscita del gas, in particolare C02, attraverso il film esterno 6. In fact, to prevent the two films from adhering to each other when the bag 1 is inserted into a containment box (bag-in-box) normally made of cardboard, at least in the upper part of each face 2 of the bag, substantially at the level of the dispensing 8, a spacer element 10 is arranged which on one side allows the films 5 and 6 of the corresponding face 2 to be kept spaced apart and, on the other, the escape of the gas, in particular C02, through the external film 6.
Nelle figure 1 e 4 l’elemento distanziatore 10 a sinistra del bocchello 7 à ̈ previsto sulla faccia frontale del sacco, mentre l’elemento a destra del bocchello, tratteggiato in figura 1, sulla faccia posteriore. In figures 1 and 4 the spacer element 10 to the left of the nozzle 7 is provided on the front face of the bag, while the element to the right of the nozzle, dashed in figure 1, is provided on the rear face.
Con riferimento alla sezione ingrandita di figura 2, si nota che l’elemento distanziatore 10 presenta un corpo di base 11 con una sede 12 di alloggiamento di un coperchio o piattello 13, e un bordo perimetrale 14, saldato alla superficie interna del film esterno 6. With reference to the enlarged section of figure 2, it can be seen that the spacer element 10 has a base body 11 with a seat 12 for housing a lid or plate 13, and a perimeter edge 14, welded to the internal surface of the external film 6.
Secondo la realizzazione illustrata in figura 2, sia nella parete di fondo 15 che nella parete laterale 16 del corpo di base 11 sono previsti fori 17, e corrispondenti fori 18, 28 sono previsti nel piattello 13, in modo che il gas, in particolare anidride carbonica, prodotta dal lievito contenuto nel sacco 1, che permea attraverso il film interno 5 può essere evacuato passando attraverso i suddetti fori 17, 18, 28 e un’apertura 19 o corrispondenti fori previsti nel film esterno 6 in corrispondenza di detto piattello 13. According to the embodiment illustrated in Figure 2, holes 17 are provided both in the bottom wall 15 and in the side wall 16 of the base body 11, and corresponding holes 18, 28 are provided in the plate 13, so that the gas, in particular anhydride carbon dioxide, produced by the yeast contained in the bag 1, which permeates through the internal film 5, can be evacuated by passing through the aforementioned holes 17, 18, 28 and an opening 19 or corresponding holes provided in the external film 6 in correspondence with said plate 13 .
L’elemento distanziatore 10 mostrato in figura 2 à ̈ ottenuto modificando una valvola di degasazione unidirezionale della stessa richiedente, dalla quale à ̈ stata asportata una membrana che impedisce il flusso di gas dall’esterno verso l’interno e nella quale sono stati praticati gli ulteriori fori 17, 28. The spacer element 10 shown in figure 2 is obtained by modifying a one-way degassing valve of the same applicant, from which a membrane has been removed that prevents the flow of gas from the outside towards the inside and in which the further holes 17, 28 have been drilled.
E’ tuttavia evidente che l’elemento distanziatore 10 può assumere una qualsiasi conformazione, fermo restando la sua funzione di tenere separati i film 5 e ò e consentire la fuoriuscita di gas attraverso di esso. However, it is evident that the spacer element 10 can assume any shape, without prejudice to its function of keeping the films 5 and ò separate and allowing gas to escape through it.
In particolare nella realizzazione illustrata, il piattello 13 può essere eliminato in quanto non necessario, prevedendo una pluralità di fori nel film esterno 6 in luogo di un’unica apertura 19. In particular in the illustrated embodiment, the plate 13 can be eliminated as it is not necessary, by providing a plurality of holes in the external film 6 in place of a single opening 19.
Prove pratiche effettuate hanno dimostrato che un solo elemento distanziatore come quello descritto ed illustrato, disposto su ciascuna faccia 2 del sacco 1, nella parte superiore del sacco, dove tendono a raccogliersi i gas emanati dal prodotto contenuto nel sacco, Ã ̈ sufficiente ad evacuare la C02 sprigionata dal lievito. Practical tests carried out have shown that a single spacer element such as that described and illustrated, arranged on each face 2 of bag 1, in the upper part of the bag, where the gases emanating from the product contained in the bag tend to collect, is sufficient to evacuate the C02 released by yeast.
E’ tuttavia evidente che, se necessario, possono essere previsti più elementi distanziatori 10 sulle facce contrapposte del sacco 1. However, it is evident that, if necessary, more spacer elements 10 can be provided on the opposite faces of the bag 1.
Sebbene, secondo l’invenzione, il film esterno 6 sia previsto continuo, cioà ̈ senza fori, à ̈ evidente che esso potrebbe essere anche forato, come quelli della tecnica nota. Although, according to the invention, the external film 6 is provided as continuous, ie without holes, it is evident that it could also be perforated, like those of the known art.
In tal caso, potrebbero essere previsti più elementi distanziatori 10, non forati, distribuiti sulla superfìcie delle facce del sacco, atti a tenere distanziati i film 5, 6 e consentire la fuoriuscita del gas attraverso i fori previsti nel film esterno 6. In this case, several spacer elements 10 could be provided, not perforated, distributed on the surface of the faces of the bag, capable of keeping the films 5, 6 apart and allowing the gas to escape through the holes provided in the external film 6.
Da quanto esposto appaiono evidenti i vantaggi dell’invenzione che consente, con mezzi semplici ed economici, la completa e rapida fuoriuscita del gas C02 prodotto dal liquido contenuto nel sacco 1. From the foregoing, the advantages of the invention appear evident, which allows, with simple and economical means, the complete and rapid escape of the C02 gas produced from the liquid contained in bag 1.
Naturalmente l’invenzione non à ̈ limitata alla particolare forma di realizzazione precedentemente descritta e illustrata nei disegni annessi, ma ad essa possono essere apportate numerose modifiche di dettaglio, alla portata del tecnico del ramo, senza per questo uscire dall’ambito dell’invenzione stessa, come definito nelle rivendicazioni annesse. Naturally, the invention is not limited to the particular embodiment previously described and illustrated in the annexed drawings, but numerous detailed modifications can be made to it, within the reach of the person skilled in the art, without thereby departing from the scope of the art. The invention itself, as defined in the appended claims.
