Description
SACCHETTO PER ASPIRAPOLVERE BAG FOR VACUUM CLEANER
REALIZZATO IN TESSUTO NON TESSUTO MADE OF NON-WOVEN FABRIC
Il presente trovato riguarda i sacchetti filtranti per aspirapolvere generalmente impiegati per uso domestico ed aziendale, e specificatamente i sacchetti monouso, ossia quelli destinati ai rifiuti insieme al loro contenuto. The present invention relates to filter bags for vacuum cleaners generally used for domestic and business use, and specifically to disposable bags, ie those intended for waste together with their contents.
La maggior parte degli apparecchi aspirapolvere sono attualmente dotati di sacchetti capaci di filtrare l'aria che accede ad essi attraverso la bocca d’aspirazione; la polvere trasportata dal flusso forzato d’aria si deposita nel sacchetto che, una volta raggiunta la sua capacità massima, viene sostituito. Most vacuum cleaners are currently equipped with bags capable of filtering the air that enters them through the suction mouth; the dust carried by the forced air flow is deposited in the bag which, once it reaches its maximum capacity, is replaced.
Nella realizzazione di tali sacchetti, le aziende produttrici di apparecchi aspirapolvere devono bilanciare due distinte necessità: la prima è relativa alla capacità filtrante del sacchetto, che deve essere estremamente pronunciata, la seconda è relativa alle proprietà strutturali del sacchetto, che devono consentire di mantenerne l’integrità per tutto il suo periodo d'utilizzazione nell’aspirapolvere. In the realization of these bags, the manufacturers of vacuum cleaners must balance two distinct needs: the first relates to the filtering capacity of the bag, which must be extremely pronounced, the second relates to the structural properties of the bag, which must allow it to maintain its integrity throughout its period of use in the vacuum cleaner.
A tal scopo, la maggior parte dei sacchetti per aspirapolvere sono realizzati in materiali aventi proprietà ibride, sovente in materiali multistrato, che presentano difficoltà costruttive e costi di realizzazione ad esse conseguenti. For this purpose, most vacuum cleaner bags are made of materials having hybrid properties, often of multilayer materials, which present constructive difficulties and consequent manufacturing costs.
Scopo del presente trovato è dunque fornire un sacchetto filtrante per aspirapolvere in cui i costi di realizzazione sono concretamente abbattuti, sia dal punto vista della scelta dei materiali che da quello deirutilizzazione dei medesimi. The aim of the present invention is therefore to provide a filter bag for vacuum cleaners in which the manufacturing costs are concretely reduced, both from the point of view of the choice of materials and of their use.
Oggetto del seguente trovato è pertanto un sacchetto filtrante per aspirapolvere comprendente un organo, costituito da due fogli di tessuto non tessuto sovrapposti e termosaldati ciascuno dei quali costituito da uno o più strati di tessuto non tessuto morbido ed adatto alla filtrazione. The object of the following invention is therefore a filtering bag for vacuum cleaners comprising an organ, consisting of two sheets of superimposed and heat-sealed non-woven fabric, each of which consists of one or more layers of soft non-woven fabric suitable for filtration.
Allo scopo di assecondare le forme del vano contenente il sacchetto di cui sono dotati gli usuali aspirapolvere, il sacchetto può assumere un perìmetro circolare e/o ellittico e/o poligonale. In order to accommodate the shapes of the compartment containing the bag with which the usual vacuum cleaners are equipped, the bag can assume a circular and / or elliptical and / or polygonal perimeter.
Gli strati di tessuto non tessuto sono sovrapposti l’uno all’altro e termosaldati tra loro in corrispondenza del loro perimetro esterno. Lo strato superiore presenta un'apertura sulla quale andrà posizionato l’elemento forato ( nel seguito chiamato cartoncino) necessario per l’ancoraggio del sacchetto stesso all’apposito dispositivo interno all’aspirapolvere. The layers of non-woven fabric are superimposed on each other and heat-sealed together at their external perimeter. The upper layer has an opening on which the perforated element (hereinafter called cardboard) necessary for anchoring the bag itself to the appropriate device inside the vacuum cleaner will be positioned.
La forma ed il perìmetro del cartoncino forato varia a seconda della marca e del modello di aspirapolvere. The shape and perimeter of the perforated cardboard varies according to the brand and model of the vacuum cleaner.
Attraverso l’apertura di detto cartoncino l’aria aspirata entra nel sacchetto dove la polvere in esso presente resta intrappolata. Through the opening of said cardboard, the sucked air enters the bag where the dust present in it remains trapped.
Grazie alla morbidezza del tessuto non tessuto impiegato, il sacchetto può gonfiarsi al meglio delle sue possibilità, prendendo il più possibile la forma del vano dell’aspirapolvere che contiene il sacchetto stesso. Thanks to the softness of the non-woven fabric used, the bag can swell to the best of its ability, taking as much as possible the shape of the vacuum cleaner compartment that contains the bag itself.
Ulteriori vantaggi e caratteristiche risulteranno evidenti dalla seguente descrizione di forme esecutive del dispositivo del presente trovato resa, a scopo esemplificativo e non limitativo, nelle tavole 1 / 2 e 2/2 di disegni allegati. Further advantages and characteristics will become evident from the following description of embodiments of the device of the present invention given, by way of non-limiting example, in tables 1/2 and 2/2 of the attached drawings.
