Description
CHIUSURA PER CONTENITORI A TENUTA MIGLIORATA CLOSURE FOR IMPROVED SEALING CONTAINERS
La presente invenzione si riferisce ad una chiusura per contenitori a tenuta migliorata. The present invention relates to a closure for containers with improved sealing.
Questo trovato si colloca nel campo delle chiusure per contenitori, in particolare contenitori aventi una imboccatura provvista di filettatura esterna sulla quale si dispone una capsula. In questa tipologia di chiusure, in particolare per contenitori contenenti liquidi speciali, quali oli o simili, à ̈ particolarmente sentita l’esigenza di avere una chiusura ottimale con massima tenuta al fine di evitare ogni tipo di inconveniente derivante da perdite inaspettate. This invention relates to the field of closures for containers, in particular containers having an opening provided with an external thread on which a capsule is arranged. In this type of closure, in particular for containers containing special liquids, such as oils or the like, the need is particularly felt to have an optimal closure with maximum seal in order to avoid any kind of inconvenience deriving from unexpected leaks.
Infatti, tali chiusure sono in genere realizzate da capsule dotate di rispettiva guarnizione che si collocano sulla imboccatura del contenitore, provviste di relativo anello di garanzia. In fact, these closures are generally made of capsules equipped with respective gaskets which are placed on the mouth of the container, provided with relative guarantee ring.
La rottura dell’anello di garanzia viene determinata dalla rotazione della capsula con trazione rottura dei ponticelli frangibili in genere disposti tra anello e bordo inferiore della capsula. The breakage of the guarantee ring is determined by the rotation of the capsule with traction breaking of the breakable bridges generally arranged between the ring and the lower edge of the capsule.
I ponticelli di garanzia, proprio per la natura della capsula in genere di materiale plastico, tendono a stirarsi al ruotare della capsula non rompendosi con estrema immediatezza. Si ha così una parziale rotazione della capsula sulla filettatura della imboccatura del contenitore ed un allontanamento della parte interna della capsula e della guarnizione, se prevista, dal bordo superiore della imboccatura del contenitore. The guarantee jumpers, due to the nature of the capsule generally made of plastic material, tend to stretch when the capsule is rotated, not breaking with extreme immediacy. In this way there is a partial rotation of the capsule on the thread of the mouth of the container and a removal of the internal part of the capsule and of the gasket, if foreseen, from the upper edge of the mouth of the container.
In questo modo, se il contenitore viene capovolto, almeno parzialmente, il liquido in esso contenuto trafila da tale spazio venutosi a creare e fuoriesce. In this way, if the container is turned upside down, at least partially, the liquid contained in it leaks from this space created and comes out.
Inoltre, in questo tipo di chiusure, quando avviene la prima apertura con rimozione della capsula per poter versare il liquido, può avvenire che la guarnizione disposta entro la capsula fuoriesca e vada perduta, se l’utilizzatore non se ne accorge. In tal modo, alla successiva richiusura, quando la capsula à ̈ totalmente avvitata sulla imboccatura, può esservi una chiusura con tenuta imperfetta. Oppure, se l’avvitamento della capsula sulla imboccatura non à ̈ completato, certamente non può realizzarsi alcuna tenuta ed un eventuale trafilamento à ̈ a questo punto certo. Furthermore, in this type of closure, when the first opening takes place with removal of the capsule to be able to pour the liquid, it may happen that the gasket placed inside the capsule comes out and is lost, if the user does not notice it. In this way, at the next reclosing, when the capsule is completely screwed on the mouth, there may be a closure with an imperfect seal. Or, if the screwing of the capsule onto the mouth is not completed, certainly no seal can be made and any leakage is certain at this point.
Per cercare di risolvere questo problema sono stati fatti molti tentativi mettendo a punto svariate soluzioni che peraltro non hanno portato ad una soluzione corretta del problema. To try to solve this problem, many attempts have been made by developing various solutions which, however, have not led to a correct solution of the problem.
Scopo generale della presente invenzione à ̈ quindi quello di risolvere gli inconvenienti sopra citati delle chiusure di questo tipo della tecnica nota in una maniera semplice, economica, funzionale ed affidabile. Altro scopo della presente invenzione à ̈ quello di realizzare una chiusura a tenuta anche in presenza di una leggera posizione non completamente avvitata della capsula sulla imboccatura del contenitore. The general purpose of the present invention is therefore to solve the aforementioned drawbacks of closures of this type of the known art in a simple, economical, functional and reliable way. Another object of the present invention is to provide a tight seal even in the presence of a slightly not completely screwed position of the capsule on the mouth of the container.
Ancora un altro scopo della presente invenzione à ̈ quello di realizzare una chiusura a tenuta che sia mantenuta anche dopo che à ̈ avvenuta la sua prima apertura. Still another object of the present invention is to provide a seal which is maintained even after its first opening has taken place.
Ulteriore scopo della presente invenzione à ̈ quello di realizzare una chiusura a tenuta nella quale la eventuale guarnizione sia con certezza disposta al disotto della capsula. A further object of the present invention is to provide a seal in which the possible gasket is with certainty positioned below the capsule.
In vista degli scopi suddetti, secondo la presente invenzione, si à ̈ pensato di realizzare una chiusura per contenitori a tenuta migliorata avente le caratteristiche esposte nelle rivendicazioni allegate. Le caratteristiche strutturali e funzionali della presente invenzione ed i suoi vantaggi nei confronti della tecnica conosciuta risulteranno ancora più chiari ed evidenti da un esame della descrizione seguente, riferita ai disegni allegati, che tra l’altro mostrano una schematizzazione di più forme di realizzazione di una chiusura per contenitori a tenuta migliorata realizzata secondo l’invenzione stessa.

Nel seguito à ̈ illustrata una chiusura per contenitori a tenuta migliorata secondo la presente invenzione, indicata complessivamente con 11 in figura 1. An improved sealing closure for containers according to the present invention is illustrated below, indicated as a whole with 11 in Figure 1.
La chiusura per contenitori comprende essenzialmente una imboccatura 12 di un contenitore 13, solo parzialmente mostrato, provvista di filettatura esterna 24, ed una capsula di copertura e chiusura 14, provvista di anello di garanzia 15 collegato alla capsula di copertura 14 tramite una serie di ponticelli frangibili 16. In figure 1 e 5 inoltre sono mostrati denti 27 inseriti in relative sedi 28 che permettono il corretto montaggio e centraggio della capsula 14 con anello di garanzia 15 sulla imboccatura 12 del contenitore senza rottura dei ponticelli 16. The closure for containers essentially comprises a mouth 12 of a container 13, only partially shown, provided with external thread 24, and a cover and closure cap 14, provided with a security ring 15 connected to the cover cap 14 by means of a series of jumpers. frangible 16. Figures 1 and 5 also show teeth 27 inserted in relative seats 28 which allow the correct assembly and centering of the capsule 14 with guarantee ring 15 on the mouth 12 of the container without breaking the jumpers 16.
La capsula di copertura 14, in forma di coppa capovolta, prevede internamente una zona dotata di filettatura 17 che termina in prossimità della sommità piana con una nervatura anulare sporgente verso l’interno 18, a diametro minore della filettatura 17, che realizza un alloggiamento. The covering capsule 14, in the form of an overturned cup, provides internally an area equipped with a thread 17 which ends near the flat top with an annular rib 18 projecting towards the inside, with a smaller diameter than the thread 17, which forms a housing .
L’anello di garanzia 15 prevede su una serie di alette 19 sporgenti verso l’interno che vanno ad impegnarsi in alette sporgenti verso l’esterno 20 realizzate in una porzione anulare incavata 21 alla base della imboccatura 12 del contenitore 13. Come meglio illustrato nella figura 6, queste alette sporgenti verso l’esterno 20 nell’esempio mostrato sono ricavate in due brevi tratti opposti della porzione anulare incavata 21 della imboccatura 12. The guarantee ring 15 provides on a series of inwardly protruding fins 19 which engage in outwardly protruding fins 20 made in a hollow annular portion 21 at the base of the mouth 12 of the container 13. How better illustrated in Figure 6, these outwardly projecting fins 20 in the example shown are formed in two short opposite portions of the hollow annular portion 21 of the mouth 12.
Le alette 19 sporgenti verso l’interno dell’anello di garanzia 15 sono cedevoli in un solo senso di rotazione così da impuntarsi nell’altro senso se portate in impegno con le alette sporgenti verso l’esterno 20 alla base dell’imboccatura 12. Questa azione di torsione realizza una sicura rottura dei ponticelli 16. The flaps 19 protruding towards the inside of the guarantee ring 15 are yielding in one direction of rotation only so as to jam in the other direction if brought into engagement with the flaps protruding towards the outside 20 at the base of the € ™ mouth 12. This twisting action achieves a sure break of the jumpers 16.
La figura 5 mostra una vista in alzata, per metà in sezione, di una prima forma di realizzazione della chiusura secondo l’invenzione. In questo esempio, oltre a quanto descritto in precedenza in relazione alla capsula di copertura 14, viene mostrata anche una guarnizione 22 piana e circolare. Questa guarnizione 22 si colloca tra la sommità piana della capsula di copertura 14 e la nervatura anulare sporgente verso l’interno 18 nell’alloggiamento ivi realizzato. Grazie alla presenza della nervatura anulare sporgente verso l’interno 18 la guarnizione 22 essendo a diametro maggiore di quello interno della nervatura 18 à ̈ ivi stabilmente posizionata. Inoltre, vantaggiosamente secondo la presente invenzione, la nervatura anulare sporgente verso l’interno 18 della capsula 14 ha un diametro prossimo o leggermente minore rispetto a quello esterno della estremità superiore della imboccatura 12 così da impegnarsi su essa e garantire comunque una buona tenuta tra le parti. Figure 5 shows an elevation view, half in section, of a first embodiment of the closure according to the invention. In this example, in addition to what has been previously described in relation to the covering capsule 14, a flat and circular gasket 22 is also shown. This gasket 22 is placed between the flat top of the covering capsule 14 and the annular rib 18 protruding inwards in the housing made therein. Thanks to the presence of the annular rib 18 protruding towards the inside, the gasket 22 having a larger diameter than the internal one of the rib 18 is stably positioned there. Furthermore, advantageously according to the present invention, the annular rib 18 of the capsule 14 protruding towards the inside has a diameter close to or slightly smaller than the external one of the upper end of the mouth 12 so as to engage on it and in any case guarantee a good seal. Between the parts.
Alla rotazione della capsula di copertura 14 rispetto alla imboccatura 12 del contenitore 13 al sollevamento della capsula verso l’alto per l’impegno reciproco delle filettature tale tenuta à ̈ mantenuta per un breve tratto anche in eventuale assenza di rottura dei ponticelli frangibili 16 tra anello di garanzia 15 e capsula di copertura 14. When the covering capsule 14 rotates with respect to the mouth 12 of the container 13 when the capsule is raised upwards due to the mutual engagement of the threads, this seal is maintained for a short distance even in the absence of breakage of the breakable bridges 16 between the guarantee ring 15 and the cover cap 14.
Peraltro, secondo l’invenzione, la rottura dei ponticelli frangibili 16 tra anello di garanzia 15 e capsula di copertura 14 avviene dopo una minima rotazione delle parti dal momento che si à ̈ prevista la doppia disposizione di alette 19, 20 descritta in precedenza. Infatti le alette 19 sporgenti verso l’interno dell’anello di garanzia 15, alla prima rotazione di svitamento, si impuntano in impegno con le alette sporgenti verso l’esterno 20 alla base dell’imboccatura 12, determinando una immediata rottura dei ponticelli frangibili 16. Moreover, according to the invention, the breakage of the frangible bridges 16 between the guarantee ring 15 and the covering cap 14 occurs after a minimum rotation of the parts since the double arrangement of fins 19, 20 described above has been provided. In fact, the tabs 19 projecting towards the inside of the guarantee ring 15, on the first unscrewing rotation, engage in engagement with the tabs projecting towards the outside 20 at the base of the mouth 12, causing an immediate break breakable jumpers 16.
Dunque tramite la disposizione nuova ed originale della chiusura secondo la presente invenzione si ha una doppia garanzia: sicura tenuta contro eventuali possibili perdite e sicura rottura immediata dei ponticelli. Therefore, by means of the new and original arrangement of the closure according to the present invention, there is a double guarantee: a secure seal against any possible leaks and a secure immediate breakage of the jumpers.
La figura 7 mostra una vista in alzata in sezione di una seconda forma di realizzazione di una chiusura secondo l’invenzione nella quale si prevede un cosiddetto “sotto-tappo†25 al posto della guarnizione 22 mostrata nel primo esempio. Figure 7 shows a sectional elevation view of a second embodiment of a closure according to the invention in which a so-called "under-cap" 25 is provided in place of the gasket 22 shown in the first example.
Il “sotto-tappo†25 si colloca parzialmente entro la imboccatura 12 a chiusura del contenitore. Una porzione cilindrica anulare 26 estesa verso il basso del “sottotappo†25 si colloca entro la imboccatura 12 del contenitore 13. Inoltre, una estremità periferica risvoltata 29 del “sotto-tappo†25 si colloca tra la sommità piana della capsula di copertura 14 e la nervatura anulare sporgente verso l’interno 18 nell’alloggiamento così individuato, rimanendo ivi stabilmente vincolata alla capsula 14. The â € œunder-capâ € 25 is partially placed within the mouth 12 to close the container. An annular cylindrical portion 26 extending towards the bottom of the â € œsubcapâ € 25 is placed within the mouth 12 of the container 13. Furthermore, a turned peripheral end 29 of the â € œsubcapâ € 25 is placed between the flat top of the cover cap 14 and the annular rib 18 protruding inwards in the housing thus identified, remaining there stably bound to the capsule 14.
Anche in questo esempio, la presenza della nervatura anulare sporgente verso l’interno 18 all’interno della capsula 14 realizza una tenuta con la estremità della parete esterna della imboccatura 12 in una ampio tratto della fase di svitamento della capsula 14 dalla imboccatura 12 del contenitore 13. Also in this example, the presence of the annular rib 18 protruding inwards inside the capsule 14 creates a seal with the extremity of the external wall of the mouth 12 in a large portion of the phase of unscrewing the capsule 14 from the mouth 12 of the container 13.
Anche in questo esempio, sono realizzate le alette 19 sporgenti verso l’interno dell’anello di garanzia 15 che, appena inizia la rotazione di svitamento della capsula 14, si impegnano con le alette sporgenti verso l’esterno 20 poste alla base dell’imboccatura 12, determinando una immediata rottura dei ponticelli frangibili 16. Also in this example, the wings 19 protruding towards the inside of the guarantee ring 15 are made which, as soon as the unscrewing rotation of the capsule 14 begins, are engaged with the protruding wings 20 placed at the base of the mouth 12, causing an immediate breakage of the frangible bridges 16.
Anche in questo esempio dell’invenzione, si ha quindi la disposizione nuova ed originale della chiusura dotata di una doppia garanzia: sicura tenuta contro eventuali possibili perdite e sicura rottura immediata dei ponticelli al primo svitamento. Also in this example of the invention, there is therefore the new and original arrangement of the closure with a double guarantee: safe seal against possible leaks and safe immediate breakage of the jumpers upon first unscrewing.
La figura 8 mostra una terza forma di realizzazione di una chiusura secondo l’invenzione nella quale la capsula internamente prevede una estensione cilindrica verso il basso 30 atta ad inserirsi e ad impegnarsi entro la estremità della imboccatura 12. Inoltre, come in precedenza nella capsula dell’invenzione si ha la presenza della nervatura anulare sporgente verso l’interno 18 all’interno della capsula 14. Figure 8 shows a third embodiment of a closure according to the invention in which the capsule internally provides a downward cylindrical extension 30 able to insert and engage within the end of the mouth 12. Furthermore, as previously in the capsule of the invention there is the presence of the annular rib protruding towards the inside 18 inside the capsule 14.
In aggiunta, in questo esempio, si prevede la collocazione di una piccola guarnizione 31 sagomata a “ciambella†, oppure a sezione quadrata o circolare, che si va a collocarsi tra estensione cilindrica verso il basso 30, nervatura anulare sporgente verso l’interno 18 ed estremità della imboccatura 12, quando avvitata, per realizzare una tenuta ancora maggiorata una volta che la capsula 14 à ̈ avvitata sul contenitore 13. In addition, in this example, a small gasket 31 shaped like a â € œmbellâ €, or with a square or circular section, is placed between a cylindrical extension downwards 30, an annular rib protruding towards the internal 18 and the end of the mouth 12, when screwed, to create an even greater seal once the capsule 14 is screwed onto the container 13.
Inutile ribadire, che anche in questo esempio sono presenti le alette 19 sporgenti verso l’interno dell’anello di garanzia 15 che, appena inizia la rotazione di svitamento della capsula 14, si impegnano con le alette sporgenti verso l’esterno 20 poste alla base dell’imboccatura 12, determinando una immediata rottura dei ponticelli frangibili 16. Needless to reiterate, that also in this example there are the fins 19 protruding towards the inside of the guarantee ring 15 which, as soon as the unscrewing rotation of the capsule 14 begins, engage with the fins protruding towards the outside 20 placed at the base of the mouth 12, causing an immediate breakage of the frangible bridges 16.
Sono presenti anche in questo esempio di realizzazione le caratteristiche precipue dell’invenzione, vale a dire: The main features of the invention are also present in this embodiment, namely:
- nervatura anulare sporgente verso l’interno 18 della capsula per realizzare una sicura tenuta contro eventuali possibili perdite, e - annular rib protruding towards the inside 18 of the capsule to provide a secure seal against any possible leaks, and
- combinazione di alette 19, 20 collaboranti tra loro sull’anello di garanzia 15 e sulla imboccatura 12 del contenitore 13 per assicurare una rottura immediata dei ponticelli al primo svitamento. - combination of fins 19, 20 collaborating with each other on the guarantee ring 15 and on the mouth 12 of the container 13 to ensure immediate breakage of the jumpers upon first unscrewing.
