Description

Domanda di brevetto per modello di utilit? dal titolo: Patent application for utility model? by title:

?Accoppiato multistrato? ? Multilayer coupled?

DESCRIZIONE DESCRIPTION

Il presente trovato riguarda un accoppiato multistrato. In particolare il presente trovato ha come oggetto un accoppiato multistrato che trova applicazione nel settore della moda e pi? in particolare nella produzione di accessori di moda (borse, borsette), abbigliamento, calzature oppure arredamento. The present invention relates to a multilayer laminate. In particular, the present invention relates to a multilayer laminate which finds application in the fashion sector and more? in particular in the production of fashion accessories (bags, handbags), clothing, footwear or furniture.

Nel settore della moda ? sempre pi? sentita l?esigenza di proporre nuovi prodotti che vadano da una parte a sostituire i prodotti tessili o pellami da molti anni ampiamente noti e dall?altra a proporre a catalogo soluzioni innovative, anche per andare incontro ad un?altra esigenza molto sentita ovverosia il riciclo di materiali che hanno esaurito il loro primo utilizzo. A tal proposito, da alcuni anni sono noti accoppiati realizzati in materiale plastico in sostituzione dei prodotti tessili standard o dei pellami. In the fashion industry? more and more? felt the need to propose new products that on the one hand replace the textile or leather products widely known for many years and on the other hand to propose innovative solutions in the catalog, also to meet another deeply felt need, namely recycling of materials that have exhausted their first use. In this regard, laminates made of plastic material have been known for some years to replace standard textile products or leathers.

Questi accoppiai, se da una parte conferiscono al prodotto finito un aspetto nuovo e magari caratteristiche tecniche peculiari del materiale plastico utilizzato (ad esempio l?impermeabilit? all?acqua), dall?altra presentano notevoli inconvenienti. If these couplings, on the one hand, give the finished product a new aspect and perhaps the specific technical characteristics of the plastic material used (for example, impermeability to water), on the other hand they have considerable drawbacks.

Un primo importante inconveniente degli accoppiati noti ? costituito dal fatto che questi accoppiati risultano per loro natura difficilmente cucibili. A first important drawback of the known couplings? consisting of the fact that these couplings are by their nature difficult to sew.

E? infatti frequente che, ad esempio capi di abbigliamento, realizzati con tali accoppiati noti, dopo un numero minimo di utilizzi, manifestino problemi di tenuta proprio in prossimit? delle cuciture applicate sugli stessi. AND? in fact, it is frequent that, for example garments, made with such known couplings, after a minimum number of uses, exhibit sealing problems precisely in the vicinity? of the seams applied on them.

Un ulteriore inconveniente degli accoppiati plastici noti ? dato dal fatto che questi risultano essere molto leggeri, ovverosia presentano una grammatura al metro molto bassa. A further drawback of the known plastic couplings? given by the fact that these turn out to be very light, that is to say they have a very low weight per meter.

Fermo restando i problemi suddetti relativi alla scarsa cucibilit?, la notevole leggerezza non consente agli stilisti di utilizzare questi accoppiati plastici di tipo noto per realizzare capi di abbigliamento o accessori come ad esempio borse e borsette, se non adatti alla stagione estiva. Without prejudice to the aforementioned problems relating to poor sewability, the considerable lightness does not allow stylists to use these plastic couplings of the known type to make garments or accessories such as bags and handbags, if not suitable for the summer season.

Scopo del presente trovato ? quindi quello di mettere a disposizione un accoppiato multistrato in grado di superare gli inconvenienti dello stato della tecnica e che sia al contempo di pratico utilizzo e di semplice ed economica realizzazione. Purpose of the present invention? therefore that of providing a multilayer laminate capable of overcoming the drawbacks of the state of the art and which is at the same time practical to use and simple and inexpensive to produce.

Ulteriore scopo del presente trovato ? quello di fornire un accoppiato multistrato avente una grammatura al metro elevata ed in grado di essere perfettamente cucibile mediante le macchine da cucire tradizionali. A further object of the present invention? that of providing a multilayer laminate having a high grammage per meter and capable of being perfectly sewable by means of traditional sewing machines.

Ulteriore scopo del presente trovato ? quello di realizzare un accoppiato multistrato nel quale sia possibile riutilizzare materiale plastico il quale abbia gi? esaurito il primo proprio ciclo di utilizzo, come ad esempio i sacchetti per la raccolta dell?immondizia. Secondo il trovato, questi scopi ed altri ancora sono raggiunti da un accoppiato multistrato comprendente le caratteristiche tecniche descritte nelle allegate rivendicazioni. A further object of the present invention? to create a multilayer laminate in which it is possible to reuse plastic material which already has? exhausted the first cycle of use, such as bags for garbage collection. According to the invention, these aims and others besides are achieved by a multilayer laminate comprising the technical characteristics described in the attached claims.

Le caratteristiche tecniche del trovato, secondo gli scopi di cui sopra, sono chiaramente descritte nelle rivendicazioni allegate e i suoi vantaggi sono evidenti dalla descrizione dettagliata che segue, con riferimento ai disegni allegati che ne illustrano una forma di realizzazione esemplificativa e non limitativa, in cui: - la figura 1 illustra, in una vista schematica in sezione, una preferita forma realizzativa di un accoppiato multistrato realizzato in accordo col presente trovato. The technical characteristics of the invention, according to the above purposes, are clearly described in the attached claims and its advantages are evident from the detailed description that follows, with reference to the attached drawings which illustrate an exemplary and non-limiting embodiment thereof, in which: Figure 1 illustrates, in a schematic sectional view, a preferred embodiment of a multilayer laminate produced in accordance with the present invention.

Secondo quanto illustrato in figura 1, con il numero 1 di riferimento ? indicata nel suo complesso una preferita forma realizzativa di un accoppiato multistrato realizzato in accordo con il presente trovato. As illustrated in figure 1, with the reference number 1? a preferred embodiment of a multilayer laminate produced in accordance with the present invention is indicated as a whole.

L?accoppiato multistrato 1 oggetto del presente trovato comprende almeno un primo strato 2 ed un secondo strato 3 di materiale plastico almeno parzialmente tra loro termofusi e uno strato di base 4 sul quale il primo 2 ed il secondo 3 strato in materiale plastico sono collegati in modo non rimovibile. The multilayer coupled 1 object of the present invention comprises at least a first layer 2 and a second layer 3 of plastic material at least partially thermally fused to each other and a base layer 4 on which the first 2 and the second 3 layers of plastic material are connected in non-removable way.

Vantaggiosamente il primo strato 2 ed il secondo strato 3 sono realizzati con il medesimo materiale plastico, preferibilmente polietilene riciclato oppure PLA (acido polilattico o polilattato). Advantageously, the first layer 2 and the second layer 3 are made of the same plastic material, preferably recycled polyethylene or PLA (polylactic acid or polylactate).

Una ulteriore soluzione realizzativa prevede invece che i materiali del primo strato 2 e del secondo strato 3 siano diversi fra loro. A further embodiment instead provides that the materials of the first layer 2 and of the second layer 3 are different from each other.

Lo strato di base 4 ? vantaggiosamente un prodotto tessile. The base layer 4? advantageously a textile product.

Ad esempio, preferibilmente, lo strato di base 4 comprende uno strato di fliselina tessile. For example, preferably, the base layer 4 comprises a layer of textile interlining.

La fliselina tessile ? una struttura di supporto a tela che pu? essere termoadevisa oppure cucicile sui suddetti strati 2, 3 in materiale plastico. The textile interlining? a canvas support structure that can? be thermoadevised or sewed on the aforesaid layers 2, 3 in plastic material.

Pu? inoltre vantaggiosamente essere realizzata in tessuto, tessuto non tessuto oppure di maglia. Pu? moreover, advantageously, it can be made of fabric, non-woven fabric or knitted fabric.

Secondo il presente trovato altre soluzioni di strato di base 4 sono comprese come ad esempio uno strato di gomma, di gommapiuma oppure di un qualsiasi materiale idoneo a conferire una adeguata struttura agli strati 2, 3 in materiale plastico e che renda gli stessi cucibili attraverso macchina da cucire di tipo tradizionale. According to the present invention, other solutions of base layer 4 are comprised, such as for example a layer of rubber, foam rubber or of any material suitable for giving an adequate structure to the layers 2, 3 in plastic material and which makes them sewable by machine. for traditional sewing.

Vantaggiosamente, lo strato di base 4 pu? essere realizzato in un materiale biodegradabile e\o compostabile come ad esempio il PLA. Advantageously, the base layer 4 can? be made of a biodegradable and / or compostable material such as PLA.

La termofusione del primo strato 2 e del secondo strato 3 avviene mediante l?utilizzo di un apposito mezzo riscaldante (ad esempio una pressa idonea oppure un ferro da stiro tradizionale) settato ad una temperatura compresa fra 150? e 250? per un tempo determinato. The thermofusion of the first layer 2 and of the second layer 3 takes place through the use of a suitable heating medium (for example a suitable press or a traditional iron) set at a temperature between 150? and 250? for a specific time.

In funzione del mezzo riscaldante utilizzato la suddetta temperatura deve essere mantenuta per un tempo compreso fra circa 10 secondi e 600 secondi (10 minuti). Depending on the heating medium used, the aforementioned temperature must be maintained for a time between about 10 seconds and 600 seconds (10 minutes).

Vantaggiosamente inoltre il primo strato 2 e\o il secondo strato 3 in materiale plastico sono realizzati a partire da sacchetti per la raccolta dell?immondizia. Advantageously, moreover, the first layer 2 and / or the second layer 3 in plastic material are made from bags for collecting garbage.

Vantaggiosamente i suddetti sacchetti provengono da punti di raccolta di sacchetti gi? precedentemente utilizzati ed in fase di riciclo. Advantageously, the aforesaid bags come from collection points for bags already? previously used and in the recycling phase.

In questa fase i sacchetti non necessitano di essere mantenuti nella forma originaria di sacchetto oppure di singolo foglio ma possono altres? trovarsi anche nella condizione di sacchetti tritati, ovverosia sottoforma di strisce di materiale. In this phase the bags do not need to be kept in the original shape of a bag or of a single sheet but can also? also being in the condition of crushed bags, ie in the form of strips of material.

Preferibilmente durante la fase di termofusione del primo strato 2 sul secondo strato 3 in materiale plastico, gli stessi strati sono protetti da un ulteriore strato temporaneo realizzato in materiale cartaceo ricoperto da particelle siliconiche. Preferably during the thermofusion step of the first layer 2 on the second layer 3 of plastic material, the same layers are protected by a further temporary layer made of paper material covered with silicone particles.

Il suddetto strato di protezione viene rimosso una volta terminata la fase di termofusione, lasciando il primo strato 2 in materiale plastico come strato a vista dell?accoppiato multistrato 1 oggetto del presente trovato. The aforesaid protective layer is removed once the thermofusion phase has ended, leaving the first layer 2 of plastic material as the visible layer of the multilayer coupling 1 object of the present invention.

Vantaggiosamente e con riferimento alla figura 1, il collegamento fra il primo strato 2 ed il secondo strato 3 con lo strato di base 4 avviene mediante una cucitura 5. Advantageously and with reference to Figure 1, the connection between the first layer 2 and the second layer 3 with the base layer 4 takes place by means of a seam 5.

In alternativa, oppure in aggiunta alla suddetta cucitura 5, il collegamento fra il primo strato 2 ed il secondo strato 3 con lo strato di base 4 avviene mediante l?utilizzo di un idoneo adesivo, a temperatura ambiente oppure termoadesivo. Alternatively, or in addition to the aforementioned seam 5, the connection between the first layer 2 and the second layer 3 with the base layer 4 occurs through the use of a suitable adhesive, at room temperature or thermo-adhesive.

Un?ulteriore soluzione prevede che il suddetto collegamento fra il primo strato 2 ed il secondo strato 3 con lo strato di base 4 avvenga mediante termofusione. A further solution provides that the aforementioned connection between the first layer 2 and the second layer 3 with the base layer 4 takes place by means of thermofusion.

L?accoppiato multistrato 1 secondo il presente trovato consegue importanti vantaggi superando gli inconvenienti dello stato dell?arte. The multilayer laminate 1 according to the present invention achieves important advantages by overcoming the drawbacks of the state of the art.

In particolare l?accoppiato multistrato 1 secondo il presente trovato permette di ottenere grammature al metro elevate e determinate dal produttore, ovverosia permette di realizzare capi di abbigliamento, accessori per moda come borse o borsette, calzature comprendenti cuciture senza che queste provochino nel tempo difetti al prodotto finito. In particular, the multilayer coupling 1 according to the present invention allows to obtain high weights per meter and determined by the manufacturer, i.e. it allows to produce clothing items, fashion accessories such as bags or handbags, footwear comprising seams without these causing defects over time. final product.

Ulteriore vantaggio consiste nel fatto di mettere a disposizione un nuovo modo di riutilizzare materiale plastico, dando allo stesso un secondo ciclo di vita, ovverosia evitando l?incremento di inquinamento da materia plastica del pianeta. Another advantage consists in making available a new way of reusing plastic material, giving it a second life cycle, ie avoiding the increase of pollution from plastic on the planet.
