Descrizione dell’invenzione avente per titolo: Description of the invention entitled:
“COPERCHIO PER CONTENITORI FLESSIBILI O SEMIRIGIDI, PARTICOLARMENTE PER PRODOTTI GRANULARI O PULVERULENTI” "LID FOR FLEXIBLE OR SEMI-RIGID CONTAINERS, ESPECIALLY FOR GRANULAR OR PULVERULENT PRODUCTS"
DESCRIZIONE DESCRIPTION
La presente invenzione ha per oggetto un coperchio per contenitori flessibili o semirigidi, particolarmente per prodotti granulari o pulverulenti, quali caffè, farine e simili. The present invention relates to a lid for flexible or semi-rigid containers, particularly for granular or powdery products, such as coffee, flour and the like.
Per il confezionamento di prodotti granulari o pulverulenti, o comune ue cori una consistenza solida vengono ampiamente utilizzati contenitori in materiale flessibile in foglio, ad esempio del tipo cosiddetto a soffietto. For the packaging of granular or powdery products, or common products with a solid consistency, containers made of flexible sheet material, for example of the so-called bellows type, are widely used.
Essi sono ricavati in un materiale monostrato o multistrato, con una o entrambe le facce esterne termosaldabili, ad esempio in polietilene. La confezione viene ottenuta in modo di per sé noto per piegature successive, effettuando saldature trasversali o longitudinali fra parti sovrapposte degli strati termosaldabili. They are made from a single or multi-layer material, with one or both of the external faces that can be heat-sealed, for example in polyethylene. The package is obtained in a per se known manner by successive folds, by carrying out transverse or longitudinal welds between superimposed parts of the heat-sealable layers.
Questi contenitori hanno l’inconveniente di non mantenere la forma, normalmente parallelepipeda, se non sono confezionati sottovuoto e, comunque, se confezionati sottovuoto, tendono ad afflosciarsi dopo l’apertura. These containers have the drawback of not maintaining the shape, normally parallelepiped, if they are not vacuum-packed and, in any case, if vacuum-packed, they tend to sag after opening.
Per ovviare a tali inconvenienti, il brevetto EP-A-0522326 propone un contenitore in materiale flessibile del tipo suddetto, irrigidito con un una piastra di base e una piastra di copertura costituita da un telaio a cornice rettangolare. To obviate these drawbacks, the patent EP-A-0522326 proposes a container made of flexible material of the aforesaid type, stiffened with a base plate and a cover plate consisting of a frame with a rectangular frame.
Un tale contenitore mantiene la forma dopo l’apertura ed è quindi utilizzabile per prelievi parziali del prodotto, fino ad esaurimento. Such a container retains its shape after opening and can therefore be used for partial withdrawals of the product, until exhaustion.
Un tale contenitore è provvisto di un coperchio, generalmente in cartone, come ad esempio descritto nel brevetto europeo EP-A-0663343, a Such a container is provided with a lid, generally made of cardboard, as described for example in the European patent EP-A-0663343, to
Si è tuttavia constatato che un tale coperchio presenta degli inconvenienti dovuti ad esempio alla presenza di intagli nel fustellato di cartone formante il coperchio, i quali tendono a determinare delle alette sporgenti dai profili laterali del contenitore, che oltre ad essere antiestetiche non consentono di mantenere dimensioni precise dei contenitori in fase di affiancamento. Inoltre, la tenuta di un tale coperchio non è a volte soddisfacente. However, it has been found that such a lid has drawbacks due for example to the presence of notches in the cardboard blank forming the lid, which tend to cause flaps protruding from the lateral profiles of the container, which in addition to being unsightly do not allow to maintain dimensions precise of the containers in the side-by-side phase. Furthermore, the tightness of such a lid is sometimes not satisfactory.
Scopo dell’invenzione è quello di eliminare gli inconvenienti illustrati, fornendo un coperchio particolarmente per contenitori semirigidi del tipo suddetto, che sia di semplice ed economica realizzazione, garantisca una buona tenuta sul prodotto, e conferisca al contenitore un aspetto esterno perfettamente uniforme. The purpose of the invention is to eliminate the disadvantages illustrated by providing a lid particularly for semi-rigid containers of the aforementioned type, which is simple and inexpensive to manufacture, guarantees a good seal on the product, and gives the container a perfectly uniform external appearance.
Questi scopi vengono raggiunti dal coperchio secondo l’invenzione che presenta le caratteristiche dell’annessa rivendicazione indipendente 1. These purposes are achieved by the lid according to the invention which has the characteristics of the attached independent claim 1.
Realizzazioni vantaggiose dell’invenzione sono descritte , nelle rivendicazioni dipendenti. Advantageous embodiments of the invention are described in the dependent claims.
il coperchio secondo l’invenzione è realizzato in materiale plastico e in una prima forma di realizzazione è del tipo a tappo, che si applica a scatto all’ imboccatura del contenitore e viene rimosso ad ogni utilizzo dello istesso, mentre in una seconda forma di realizzazione è del tipo a cerniera e rimane costantemente applicato al contenitore, fino all’esaurimento del prodotto, apr !endosi per ribaltamento. the lid according to the invention is made of plastic material and in a first embodiment is of the cap type, which is snapped onto the mouth of the container and is removed each time it is used, while in a second embodiment it is of the hinged type and remains constantly applied to the container, until the product is used up, opening by overturning.
Il coperchio a tappo, a contenitore sigillato, prima dell’apertura, è applicato sullo stesso, in posizione leggermente sollevata, in modo che rimboccatura del contenitore sia chiusa da un diaframma pelabile o strato di materiale easy open termosaldato lungo il perimetro del telaietto a cornice rettangolare, strato che viene asportato alla prima utilizzazione. Per la richiusura del contenitore, il coperchio a tappo viene abbassato sullo stesso, in modo che una sua protuberanza interna vada ad agganciarsi con il bordo interno del telaietto, garantendo così un’ottima tenuta. The cap lid, with a sealed container, before opening, is applied to it, in a slightly raised position, so that the tucking of the container is closed by a peelable diaphragm or layer of easy open heat-sealed material along the perimeter of the frame. rectangular, layer that is removed at the first use. To re-close the container, the cap lid is lowered onto it, so that an internal protuberance hooks onto the inner edge of the frame, thus ensuring an excellent seal.
Il coperchio a cerniera presenta una cornice di base o mantello i che si dispone intorno al bordo superiore del contenitore, ad un lato del quale è incernierata una piastra di chiusura fungente da coperchio vero e proprio. The hinged lid has a base frame or skirt i which is arranged around the upper edge of the container, to one side of which a closure plate acting as a real lid is hinged.
Convenientemente la cornice di base è incollata e saldata al bordo del contenitore, ma si può prevedere anche il caso in cui essa sia applicabile con un incastro a scatto a detto telaietto del contenitore, come il coperchio a tappo. Conveniently, the base frame is glued and welded to the edge of the container, but it is also possible to foresee the case in which it is applicable with a snap-fit to said frame of the container, such as the cap lid.
L’imboccatura del contenitore è anche in questo caso convenientemente chiusa da un diaframma pelabile (materiale easy open) e viene asportato all’atto dell’apertura del contenitore. The mouth of the container is also in this case conveniently closed by a peelable diaphragm (easy open material) and is removed when the container is opened.
La chiusura del coperchio a cerniera è garantita da un incastro dello stesso con il lato di detta cornice perimetrale opposto a quello di incemieramento. The closure of the hinged lid is ensured by an interlocking of the same with the side of said perimeter frame opposite to that of hinging.
Il coperchio secondo l’invenzione presenta altresì sulla sua superficie superiore una sede leggermente ribassata, destinata ad accogliere un foglio di plastica con eventuali scritte o disegni stampati, servente a personalizzare il coperchio, senza dover effettuare interventi direttamente sullo stesso, come è necessario nei coperchi della tecnica nota. The lid according to the invention also has a slightly lowered seat on its upper surface, intended to accommodate a plastic sheet with any printed writings or drawings, serving to customize the lid, without having to carry out interventions directly on it, as is necessary in lids. of the known art.
Convenientemente, il foglio in plastica che viene applicato al coperchio viene recuperato dal processo produttivo del contenitore dalla fu steli atura dell’apertura di imboccatura dello stesso con materiale che finora costituiva uno scarto. Conveniently, the plastic sheet that is applied to the lid is recovered from the production process of the container by the melting of the mouth opening of the same with material that up to now constituted a waste.

la Fig. 10 è un ingrandimento del particolare racchiuso nel cerchio A di Fig. 9. Fig. 10 is an enlargement of the detail enclosed in circle A of Fig. 9.
Con riferimento a tali figure, e per ora alle Fig. da 1 a 5, con 1 è stato indicato genericamente un contenitore di tipo semirigido, ad esempio del tipo descritto in EP-.A-0522326, particolarmente per il contenimento di prodotti granulari o in polvere, quale caffè e simili. With reference to these figures, and for now to Figs. 1 to 5, 1 has generically indicated a container of the semi-rigid type, for example of the type described in EP-.A-0522326, particularly for containing granular products or powder, such as coffee and the like.
Il contenitore 1 ha una forma parallelepipeda, con un’ampia apertura superiore 3 (vedere in particolare Fig. 1), sigillata da un diaframma pelabile 2 del<' >tipo easy open (Figg. 3, 4), che viene asportato all’atto delfapertura del contenitore, in quale può venire richiuso mediante il coperchio secondo l’invenzione, indicato globalmente con il numero di riferimento 4. The container 1 has a parallelepiped shape, with a wide upper opening 3 (see in particular Fig. 1), sealed by a peelable diaphragm 2 of the easy open type (Figs. 3, 4), which is removed at the act of opening the container, in which it can be closed by means of the lid according to the invention, globally indicated with the reference number 4.
Come visibile in Fig. 1, la detta apertura 3 determina nella parete superiore del contenitore 1 una cornice perimetrale 5, al di sotto della quale è disposto un telaietto di rinforzo 6, convenientemente in materiale plastico. As can be seen in Fig. 1, said opening 3 determines in the upper wall of the container 1 a perimeter frame 5, under which a reinforcing frame 6 is arranged, conveniently made of plastic material.
Il coperchio 4, ricavato convenientemente in materiale plastico, è del tipo a tappo, e presenta una base superiore sostanzialmente piana 7 e un mantello periferico 8. Internamente, a detto mantello periferico 8 è previsto un secondo mantello, continuo o discontinuo 9, ad una distanza dal mantello esterno 8 all’incirca pari alla larghezza del telaietto 6. The lid 4, conveniently made of plastic material, is of the plug type, and has a substantially flat upper base 7 and a peripheral shell 8. Internally, said peripheral shell 8 is provided with a second continuous or discontinuous shell 9, with a distance from the outer casing 8 approximately equal to the width of the frame 6.
Il mantello interno 9, o comunque le paretine sporgenti inferiormente dal coperchio 4, presenta un dentino 10 atto ad impegnarsi a scatto con il bordo interno del telaietto 6. <:>The inner shell 9, or in any case the small walls protruding from the bottom of the lid 4, has a tooth 10 able to snap into place with the inner edge of the small frame 6. <:>
Quando il contenitore 1 è sigillato, prima dell’apertura, il coperchio 4 è posizionato leggermente sollevato dal contenitore 1, almeno della distanza pari alla lunghezza di detto mantello 9, in modo che tale mantello non vada ad interferire con il diaframma pelabile 2 che sigilla il contenitore, come mostrato in Fig. 4. When the container 1 is sealed, before opening, the lid 4 is positioned slightly raised from the container 1, at least by the distance equal to the length of said shell 9, so that said shell does not interfere with the peelable diaphragm 2 which seals the container, as shown in Fig. 4.
Dopo la prima apertura del contenitore 1 e quindi l’asportazione del diaframma pelabile 2, il contenitore può essere richiuso riposizionando il coperchio 4 sullo stesso, abbassandolo fino a che il dentino 10 del mantello interno 9 va in impegno con il bordo interno del telaietto 6, come mostrato in Fig. 5. After the first opening of the container 1 and then the removal of the peelable diaphragm 2, the container can be closed by repositioning the lid 4 on the same, lowering it until the tooth 10 of the inner shell 9 engages with the inner edge of the frame 6 , as shown in Fig. 5.
In tale condizione, oltre a una chiusura sicura, viene garantita un’ottima tenuta tra coperchio e contenitore, anche per la presenza del doppio mantello 8, 9 che circonda il telaietto 6. In this condition, in addition to a secure closure, an excellent seal is guaranteed between the lid and the container, also due to the presence of the double skirt 8, 9 that surrounds the frame 6.
Il coperchio 4, una volta applicato al contenitore 1, come visibile ad esempio in Fig. 5, determina un ingombro minimo sul contorno del contenitore stesso, mantenendo nel tempo le dimensioni iniziali, garantendo così un preciso affrancamento di più contenitori. The lid 4, once applied to the container 1, as can be seen for example in Fig. 5, creates a minimum bulk around the container itself, maintaining the initial dimensions over time, thus ensuring a precise freeing of several containers.
Eventualmente, il tappo 4, ad esaurimento del contenuto del contenitore 1, può essere usato per chiudere un nuovo contenitore, che quindi sarà venduto senza tappo 4, ma solo con il diaframma pelabile 2 ed un eventuale involucro protettivo. Optionally, the cap 4, once the contents of the container 1 are exhausted, can be used to close a new container, which will therefore be sold without the cap 4, but only with the peelable diaphragm 2 and an optional protective wrapping.
Sulla parete superiore 7 del coperchio 4 è ricavato un ribasso o incavò 11, di forma rettangolare e con perimetro parallelo al perimento esterno del copèrchio, atto ad accogliere un foglio plastico 12 delle stesse dimensioni, che viene incollato o termosaldato al coperchio 4. Tale foglio 12 reca convenientemente delle scritte e/o disegni atti a personalizzare il coperchio 4, senza dover stampare direttamente sul coperchio, cosa che comporta indubbi vantaggi. On the upper wall 7 of the lid 4 there is a recess or recess 11, rectangular in shape and with a perimeter parallel to the outer perimeter of the lid, suitable for receiving a plastic sheet 12 of the same size, which is glued or heat-sealed to the lid 4. This sheet 12 conveniently bears writings and / or drawings suitable for personalizing the lid 4, without having to print directly on the lid, which entails undoubted advantages.
Peraltro, tale foglio plastico rettangolare 12 viene convenientemente recuperato dagli scarti di fustellatura dell’apertura 3 del contenitore in f ìase di produzione dello stesso, a partire da un film plastico. Moreover, this rectangular plastic sheet 12 is conveniently recovered from the punching scraps of the opening 3 of the container in the production phase of the same, starting from a plastic film.
Viene ora descritta la seconda forma di realizzazione dell’ invenzione, facendo riferimento alle Figg. da 6 a 10, nelle quali verranno utilizzati gli stessi numeri di riferimento impiegati in relazione alla prima forma realizzativa descritta, per contraddistinguere due parti uguali o simili. The second embodiment of the invention is now described, referring to Figs. 6 to 10, in which the same reference numbers used in relation to the first embodiment described will be used to distinguish two identical or similar parts.
In questo caso, il coperchio 4 è del tipo a cerniera e presenta una 'piastra superiore 7 incernierata ad un lato del mantello 8, che viene fissato mediante adesivo o per termosaldatura al bordo superiore esterno del contenitore 1. In this case, the lid 4 is of the hinged type and has an upper plate 7 hinged to one side of the shell 8, which is fixed by means of adhesive or by heat sealing to the upper outer edge of the container 1.
Internamente al mantello 8 è previsto un secondo mantello 9, più corto, che si attesta, contro la parete superiore del telaietto 6. Inside the shell 8 there is a second, shorter shell 9 which abuts against the upper wall of the small frame 6.
Secondo un’alternativa a quanto illustrato nelle figure annesse, il mantello interno 9 può avere la stessa configurazione del corrispondente mantello 9 della prima forma di realizzazione, in modo che il sistema di aggancio del coperchio 4 al contenitore avvenga senza mezzi adesivi o saldature, ma per l’impegno con il bordo interno del telaietto 6. Ciò può risultare vantaggioso qualora si volesse riutilizzare il coperchio a cerniera 4 dopo lo svuotamento del contenitore 1. I Tornando alla descrizione delle Figg. da 6 a 10, la piastra di copertura 7 presenta, sul lato 20 opposto a quello di incemieramento 19, un dentino 21 che in chiusura del coperchio va ad impegnarsi a scatto in una corrispondente cavità 22 ricavata in detto mantello interno 9, come meglio visibile in Fig. 10, garantendo così una chiusura sicura del contenitore. Per migliorare la tenuta può' essere prevista una guarnizione agente tra la piastra di copertura 7 e il mantello 9. According to an alternative to what is illustrated in the attached figures, the inner shell 9 can have the same configuration as the corresponding shell 9 of the first embodiment, so that the coupling system of the lid 4 to the container takes place without adhesive means or welding, but for engagement with the inner edge of the small frame 6. This can be advantageous if the hinged lid 4 is to be reused after emptying the container 1. Returning to the description of Figs. from 6 to 10, the cover plate 7 has, on the side 20 opposite to the hinging side 19, a tooth 21 which, when closing the cover, snaps into a corresponding cavity 22 obtained in said inner shell 9, as better visible in Fig. 10, thus ensuring a safe closure of the container. To improve the seal, a gasket acting between the cover plate 7 and the shell 9 can be provided.
L’apertura del coperchio è agevolata da una linguetta di presa 23 sporgente frontalmente dalla piastra superiore 7. The opening of the lid is facilitated by a grip tab 23 protruding frontally from the upper plate 7.
Anche in questo caso sulla parete superiore della piastra 7 può essere applicato un foglio adesivo 12 esattamente come quello della realizzazione precedente. Also in this case an adhesive sheet 12 can be applied to the upper wall of the plate 7 exactly like that of the previous embodiment.
In entrambe le realizzazioni descritte, tale foglio adesivo 12, opportunamente stampato, può essere applicato alla faccia interna della piastra 7, fungendo cosi ad esempio da buono d’acquisto. In both embodiments described, this adhesive sheet 12, suitably printed, can be applied to the internal face of the plate 7, thus acting for example as a purchase voucher.
Da quanto esposto appaiono evidenti vantaggi dell’ invenzione, che risolve pienamente i problemi dei coperchi della tecnica nota. From the foregoing, obvious advantages of the invention appear, which fully solves the problems of the lids of the known art.
Naturalmente l’invenzione non è limitata alle particolari forme di realizzazione precedentemente descritte e illustrate nei disegni annessi, ma ad essa possono essere apportate numerose modifiche di dettaglio alla portata del tecnico del ramo, da intendersi rientranti nell’ambito definito dalle rivendicazioni annesse. Of course, the invention is not limited to the particular embodiments previously described and illustrated in the attached drawings, but numerous detailed changes within the reach of the skilled in the art can be made to it, to be understood as falling within the scope defined by the attached claims.
