Claims (2)

RIVENDICAZIONI 1. Apparecchio atto a tenere assieme due o più bordi sovrapposti e ripiegati di fogli, sacchi o bustine e nel contempo assicurare una forte tenuta nel senso di trazione longitudinale, questo apparecchio essendo caratterizzato nel consistere di due pareti (3-5) parallele unite fra loro nella loro parte superiore e dal fatto che almeno ima di queste pareti (3) è provvista al suo interno di una sporgenza (6) a forma di becco volto verso l'alto, atta a ritenere la ripiegatura dei fogli introdotti, assicurandone la tenuta (fig. 1).1. Apparatus suitable for holding together two or more overlapping and folded edges of sheets, bags or sachets and at the same time ensuring a strong seal in the longitudinal traction direction, this apparatus being characterized in consisting of two parallel walls (3-5) joined between their upper part and by the fact that at least one of these walls (3) is provided internally with a protrusion (6) in the shape of a beak facing upwards, suitable for retaining the folding of the introduced sheets, ensuring their tightness (fig.1). 2. Apparecchio come da rivendicazione 1, caratterizzato dal fatto che presenta una impugnatura, oppure dei ganci, fori od anelli di presa (fig. 4).2. Apparatus according to claim 1, characterized in that it has a grip, or hooks, holes or gripping rings (fig. 4). Moltissime sono le applicazioni della tecnica riguardo i problemi di imballaggio. Per il commercio al dettaglio furono molto usati sacchetti di carta, progressivamente sostituiti da sacchetti di plastica, perché questi 'ultimi permettono un sistema di impugnatura migliore.There are many applications of the technique regarding packaging problems. Paper bags were widely used for the retail trade, progressively replaced by plastic bags, because the latter allow for a better grip system. Fra le ultime applicazioni ai sacchetti di carta figurano le impugnature forate a due riprese nella parte alta del sacco, così che ripiegando l'orlo superiore le due aperture combaciano e danno la possibilità di impugnarle. Per evitare che la carta si strappi le parti superiori del sacco devono però essere rinforzate con cartoncini e ciò richiede maggior lavorazione con conseguente aumento del costo. Con questo sistema si deve sacrificare circa il venti per cento della lunghezza del sacco ed inoltre c'è l'inconveniente che l'involucro tende sempre ad aprirsi appena liberato dalla presa della mano. Un altro sistema è l'applicazione di un nastro di carta gommata che chiude il sacchetto. A questo nastro è incorporata una cordicella che dà la possibilità di portare l'involucro. Anche questo sistema presenta diversi svantaggi. Bisogna anzitutto umidificare volta per volta il nastro gommato e capita sovente che un cliente perda il sacchetto per via che il nastro si è scollato perché troppo bagnato o viceversa. Inoltre una volta chiuso l'involucro non lo si può più riaprire senza rompere la carta. Anche dal lato estetico non è ottimale. Con l'applicazione della plastica si sono cercate diverse soluzioni ma non esiste finora un sistema che garantisca una chiusura a tutta prova e sia nel contempo vantaggiosa anche dal lato economico.Among the latest applications to paper bags are the handles perforated in two stages in the upper part of the bag, so that by folding the upper edge the two openings fit together and give the possibility of gripping them. However, to prevent the paper from tearing, the upper parts of the bag must be reinforced with cardboard and this requires greater processing with a consequent increase in cost. With this system about twenty per cent of the length of the bag has to be sacrificed and furthermore there is the drawback that the casing always tends to open as soon as it is released from the hand's grip. Another system is the application of a gummed paper tape which closes the bag. A cord is incorporated into this ribbon which makes it possible to carry the wrapper. This system also has several disadvantages. First of all, it is necessary to humidify the gummed tape each time and it often happens that a customer loses the bag because the tape has come unstuck because it is too wet or vice versa. Furthermore, once the wrapper is closed, it cannot be reopened without breaking the paper. Even from an aesthetic point of view it is not optimal. Various solutions have been sought with the application of plastic, but up to now there is no system that guarantees a fully tested closure and is at the same time advantageous from an economic point of view. L'uso della plastica per gli imballaggi dovrebbe poter essere ridotto nei limiti del possibile anche per motivi ecologici. Proprio in questo senso l'apparecchio proposto e conforme alla rivendicazione 1, potrebbe avere effetti posi-5 tivi, inducendo industriali e commercianti a ritornare agli imballaggi di carta per motivi di praticità o economia.The use of plastic for packaging should be able to be reduced as much as possible also for ecological reasons. Precisely in this sense the proposed apparatus, in accordance with claim 1, could have positive effects, inducing industrialists and traders to return to paper packaging for reasons of practicality or economy. Le figure del disegno mostrano la forma di esecuzione dell'apparecchio secondo l'invenzione e il modo d'uso.The figures of the drawing show the embodiment of the apparatus according to the invention and the method of use. Nella fig. 1 è rappresentata ima sezione dell'apparec-ìo chio, ove su una 3 delle due pareti 3-5 parallele si vede la sporgenza 6 a forma di becco atta a ritenere la ripiegatura dei bordi superiori di un sacchetto.In fig. 1 shows a section of the apparatus, where on one 3 of the two parallel walls 3-5 can be seen the protrusion 6 in the shape of a beak suitable for retaining the fold of the upper edges of a bag. Nella fig. 2 è rappresentato un contenitore a fórma di sacco 8 i cui bordi superiori sono stati preventivamente ri-15 piegati due volte 9 in funzione dell'uso dell'apparecchio come a fig. 1.In fig. 2 shows a sack-shaped container 8 whose upper edges have been previously folded 15 twice 9 according to the use of the apparatus as in fig. 1. Nella fig. 3 i bordi ripiegati del sacchetto sono stati spinti dal basso all'alto dentro l'apparecchio.In fig. 3 the folded edges of the bag were pushed from bottom to top into the appliance. Appena oltrepassato il becco 6 di trattenuta, la parte 20 ripiegata tenderà a riaprirsi inserendosi nell'angolo formato dal becco stesso, assicurando così la tenuta alla trazione, giacché la ripiegatura imprigionata tra le due pareti 3-5 non potendo estendersi in larghezza, oppone una forte resistenza ad una trazione in senso longitudinale. 25 Per contenitori in carta molto sottile o plastica, è previsto di rinforzare la ripiegatura di modo che la resistenza alla trazione risulti assicurata.As soon as the retaining spout 6 has passed, the folded part 20 will tend to reopen by inserting itself into the angle formed by the spout itself, thus ensuring resistance to traction, since the folding trapped between the two walls 3-5, not being able to extend in width, opposes a strong resistance to traction in the longitudinal direction. 25 For very thin paper or plastic containers, it is foreseen to reinforce the folding so that the tensile strength is ensured. Se gli orli degli involucri vengono ripiegati più volte, si otterrà facilmente un'ottima chiusura anche per merci 30 finemente granulate o polveri.If the edges of the wrappers are folded over several times, an excellent seal will easily be obtained even for finely granulated or powdered goods 30 . Nella fig. 4 si può rilevare un altro fattore di praticità, in quanto quest'apparecchio può essere facilmente rimosso, indi riapplicato al medesimo contenitore senza inconveniente alcuno.In fig. 4 another practical factor can be seen, since this device can be easily removed and then reapplied to the same container without any inconvenience. 35 Dal lato economico esiste pure la possibilità di riutilizzare sacchetti già usati ma in stato ancora presentabile.35 From the economic point of view, there is also the possibility of reusing bags that have already been used but are still presentable. Nell'ottica di un uso pratico questo sistema potrebbe trovare applicazione per esempio:With a view to practical use, this system could find application for example: 40 a) bustine per polveri, sementi, altre minutaglie b) buste per uso di ufficio, spedizioni per posta c) sacchetti con prodotti commestibili d) contenitori di carta in uso nei negozi e) sacchi contenenti mangimi ecc.40 a) sachets for powders, seeds, other small items b) envelopes for office use, shipments by post c) bags with edible products d) paper containers used in shops e) bags containing feed, etc. vv 1 foglio disegni1 drawing sheet
