Abstract

The method for packaging pillows or mattresses made of expanded polyurethane, including those containing springs (1), consists in wrapping the internal parts (3,4) in soft plastic material (5), then placing them under a press or connecting them to an aspirating pump, so as to substantially reduce their volume by expelling the air they contain, with the wrapping (5) then being heat-sealed. The bulk of the said pillows or mattresses is thus considerably reduced for storage and transportation, yet they regain their original volume as soon as the said wrapping (5) is opened by the user. <IMAGE>

RIVENDICAZIONI 1. Procedimento per ottenere cuscini o materassi confezionati sottovuoto, caratterizzato dal fatto che la parte interna (3, 4), conformata in poliuretano espanso, viene inserita in un involucro di plastica floscia (5) e dal fatto che dall'involucro, con una pompa aspirante od una pressa, viene espulsa tutta l'aria, effettuando poi una saldatura a caldo di detto involucro, in modo tale da realizzare la tenuta interna e quindi la riduzione dello spessore.1. Process for obtaining vacuum-packed cushions or mattresses, characterized in that the internal part (3, 4), shaped in expanded polyurethane, is inserted into a soft plastic casing (5) and in the fact that from the casing, with a suction pump or a press, all the air is expelled, then carrying out a heat welding of said casing, in such a way as to create the internal seal and therefore the reduction of the thickness. 2. Cuscino o materasso confezionato risultante dal procedimento secondo la rivendicazione 1, caratterizzato dal fatto di' comprendere all'interno delle molle (1), con delle strutture di fissaggio (2) e la struttura interna (3) in poliuretano espanso, un rivestimento di contenimento (4), in tessuto di ogni tipo chiuso con cuciture, e il rivestimento esterno (5) in materiale plastico floscio, saldato a perfetta tenuta stagna una volta realizzato il vuoto interno.2. A made-up cushion or mattress resulting from the process according to claim 1, characterized in that it comprises inside the springs (1), with fixing structures (2) and the internal structure (3) in expanded polyurethane, a covering containment (4), in fabric of all types closed with stitching, and the external covering (5) in soft plastic material, welded to ensure perfect watertightness once the internal vacuum has been created. L'invenzione concerne un procedimento per ottenere cuscini o materassi confezionati sotto-vuoto, in modo tale da presentare il minimo ingombro di trasporto e magazzina-mento, ma tali da tornare alle dimensioni e funzionalità normali all'atto dell'apertura dei loro involucri a tenuta d'aria.The invention relates to a method for obtaining vacuum-packed cushions or mattresses, in such a way as to present the minimum bulk for transport and storage, but such as to return to their normal dimensions and functionality upon opening their wrappings at air tightness. È noto che numerosi' sono gli inconvenienti che si verificano quando si devono immagazzinare e trasportare rilevanti quantitativi di materassi, cuscini e simili, a molle o di altro tipo. Si tratta infatti di prodotti che pur relativamente leggeri sono caratterizzati da grandi volumi di ingombro. Inoltre la maggioranza dei suindicati prodotti è evidentemente non lavabile in quanto mancano di tenuta stagna, le eventuali infiltrazioni di acqua e solventi determinerebbero fenomeni irreversibili sulle molle e sui componenti interni,It is known that numerous drawbacks occur when it is necessary to store and transport large quantities of mattresses, cushions and the like, with springs or of other types. In fact, these are products which, although relatively light, are characterized by large overall dimensions. Furthermore, the majority of the aforementioned products is obviously not washable as they lack watertightness, any infiltration of water and solvents would cause irreversible phenomena on the springs and internal components, tali da degradare in brevissimo tempo qualsiasi struttura.such as to degrade any structure in a very short time. Scopo dell'invenzione è quello di realizzare cuscini, materassi e simili, anche dotati di molle interne, confezionati sottovuoto e quindi presentanti un minimo spessore d'ingombro, e rivestiti esternamente di materiali non permeabili, atti ad impedire scambi gassosi con l'atmosfera, al fine di consentirne il trasporto ed il magazzinaggio, a parità di volume occupato, in quantità molto superiori a quelli tradizionali. Inoltre, mostrandosi anche a tenuta di agenti liquidi, i prodotti saranno perfettamente lavabili e durevoli nel tempo, essendo impedita ogni corrosione interna ed inoltre giungeranno agli utenti in perfette condizioni d'igiene.The object of the invention is to make cushions, mattresses and the like, also equipped with internal springs, vacuum-packed and therefore having a minimum overall thickness, and covered externally with non-permeable materials, capable of preventing gaseous exchanges with the atmosphere, in order to allow their transport and storage, for the same occupied volume, in much higher quantities than the traditional ones. Furthermore, as they are also liquid-tight, the products will be perfectly washable and durable over time, any internal corrosion being prevented, and furthermore they will reach the users in perfect hygienic conditions. Lo scopo si raggiunge inserendo la struttura interna in poliuretano espanso, costituente il cuscino o materasso, in un involucro di plastica floscia e disponendo il tutto al di s sotto di una pressa o collegandolo ad una pompa aspirante ed effettuando quindi una saldatura a caldo di detto involucro in modo tale da realizzare la tenuta interna atta a mantenere la riduzione dello spessore. Di conseguenza una volta aperti detti involucri da parte degli utenti i cuscini e simili io tornano, per l'entrata dell'aria nel loro interno, alle dimensioni ed elasticità originarie.The purpose is achieved by inserting the internal structure in expanded polyurethane, constituting the cushion or mattress, in a soft plastic casing and arranging the whole underneath in a press or by connecting it to a suction pump and then carrying out a hot welding of said casing in such a way as to create the internal seal suitable for maintaining the reduction in thickness. Consequently, once said casings have been opened by the users, the cushions and the like return, due to the entry of air into their interior, to their original dimensions and elasticity. L'invenzione viene ora illustrata in dettaglio con riferimento all'allegato disegno che mostra una sezione laterale di un cuscino, comprensivo anche di molle. Nella figura sono ìs state indicate con 1 le molle di tipo tradizionale, presenti all'interno del cuscino in un numero differenziato in relazione alle dimensioni e alle esigenze di funzionalità, fissate a strutture 2, realizzabili in poliuretano espanso schiumato o simile, con 3 la struttura interna in poliuretano espanso saldato 20 perimetralmente o in altre fibre sintetiche o naturali, con 4 un involucro di contenimento, in tessuto di qualsiasi tipo, chiuso con cuciture, chiusure-lampo, bottoni automatici o simili, e con 5 un involucro esterno in materiale plastico floscio, saldato a perfetta tenuta stagna una volta realiz-25 zato il vuoto interno.The invention is now illustrated in detail with reference to the attached drawing which shows a side section of a cushion, also including the springs. In the figure, the traditional type of springs have been indicated with 1, present inside the cushion in a differentiated number in relation to the dimensions and functional requirements, fixed to structures 2, which can be made in polyurethane foam or similar, with 3 the internal structure in expanded polyurethane 20 welded around the perimeter or in other synthetic or natural fibres, with 4 a containment casing, in fabric of any type, closed with stitching, zip fasteners, automatic buttons or the like, and with 5 an external casing in material soft plastic, welded for perfect watertightness once the internal vacuum has been created. La realizzazione dei cuscini o materassi può essere così descritta: si realizza anzitutto la struttura 3 contenente eventualmente le molle 1 sulle strutture 2; si inserisce quindi detta struttura 3 chiusa nell'involucro 4, all'interno dell'in-30 volucro esterno 5 e, posto il tutto sotto una pressa, si determina la sua deformazione ed appiattimento, effettuando la saldatura a caldo finale del rivestimento 5. A seguito dell'azione della pressa il prodotto rimane a tenuta d'aria e presenta uno spessore minimo, con il quale molto convenien-35 temente avviene il trasporto e il magazzinamento, fino a quando l'utente aprirà detto contenitore 5 e il cuscino, materasso o simile, in virtù della propria elasticità, riacquisterà le dimensioni normali.The making of the cushions or mattresses can be described as follows: first of all the structure 3 is made, possibly containing the springs 1 on the structures 2; then said closed structure 3 is inserted into the casing 4, inside the external casing 5 and, placing the whole under a press, its deformation and flattening is determined, carrying out the final heat welding of the covering 5. Following the action of the press, the product remains airtight and has a minimum thickness, with which transport and storage take place very conveniently, until the user opens said container 5 and the cushion, mattress or similar, by virtue of its elasticity, will regain its normal dimensions. Il vuoto interno può essere realizzato anche con adatte 40 pompe spiranti anziché mediante l'azione della pressa.The internal vacuum can also be achieved with suitable 40 suction pumps instead of by the action of the press. L'invenzione è stata qui illustrata con riferimento ad una forma di attuazione preferita ma resta inteso che potranno essere apportate varianti in forma, disposizioni e proporzioni senza per questo uscire dal quadro della pre-45 sente invenzione.The invention has been illustrated here with reference to a preferred embodiment but it is understood that variations in shape, arrangements and proportions may be made without thereby departing from the scope of the present invention. vv 1 foglio disegni1 drawing sheet
