Description
DESCRIZIONE DESCRIPTION
Forma oggetto della presente invenzione una chiusura per una cannuccia di un imballo flessibile a pareti sottili, solitamente denominato “pouch”. The subject of the present invention is a closure for a straw of a flexible thin-walled packaging, usually referred to as a "pouch".
Come è noto, tali imballi sono enormemente utilizzati per contenere prodotti quali succhi e purea di frutta, yoghurt, bevande energetiche e simili. As is known, such packages are widely used to contain products such as fruit juices and purees, yoghurt, energy drinks and the like.
Essi sono apprezzati soprattutto per l’enorme comodità di utilizzo, in quanto la cannuccia consente di erogare il prodotto direttamente in bocca, e, per quanto riguarda i prodotti per bambini, per la componente di gioco insita nell’utilizzo della cannuccia. They are especially appreciated for the enormous ease of use, as the straw allows you to dispense the product directly into the mouth, and, as regards products for children, for the play component inherent in the use of the straw.
Solitamente, l’imballo comprende un tappo avvitato alla cannuccia, provvisto di un sigillo di garanzia che ne evidenzia il primo utilizzo. Usually, the packaging includes a cap screwed to the straw, provided with a guarantee seal that highlights the first use.
Una volta svitato il tappo dalla cannuccia, questo rimane in mano all’utilizzatore, solitamente nell’altra mano rispetto a quella utilizzata per bere, oppure, nel caso di bambini, viene consegnato all’accompagnatore. Essendo scomodo tenerlo in mano e viste le dimensioni ridotte, il rischio è che il tappo sia gettato alla prima occasione o che sia perso, senza tener conto del corretto smaltimento dello stesso. Once the cap is unscrewed from the straw, it remains in the user's hand, usually in the other hand than the one used for drinking, or, in the case of children, it is given to the attendant. Since it is inconvenient to hold it in the hand and given its small size, the risk is that the cap is thrown away at the first opportunity or that it is lost, without taking into account its correct disposal.
Scopo della presente invenzione è quello di realizzare una chiusura per una cannuccia di un imballo flessibile a pareti sottili che soddisfi le esigenze del settore e superi gli inconvenienti di cui si è detto con riferimento all’arte nota. The purpose of the present invention is to provide a closure for a straw of a flexible thin-walled packaging that meets the needs of the sector and overcomes the drawbacks mentioned with reference to the prior art.

Con riferimento alle tavole allegate, con 1 si è complessivamente indicata una chiusura per una cannuccia di un imballo flessibile a pareti sottili, secondo una forma di realizzazione della presente invenzione. With reference to the attached tables, 1 indicates as a whole a closure for a straw of a flexible packaging with thin walls, according to an embodiment of the present invention.
Preferibilmente, la chiusura 1 comprende un corpo chiusura 2 ed un sovratappo 4, cui il corpo chiusura 2 è applicabile stabilmente. Preferably, the closure 1 comprises a closure body 2 and an overcap 4, to which the closure body 2 can be applied stably.
Il corpo chiusura 2 comprende una parete corpo 6 anulare avente un asse principale X ed una predefinita altezza lungo detto asse principale X; la parete corpo 6 si estende fra una base chiusura 10 ed un bordo parete corpo 7 anulare per l’inserimento del corpo chiusura 2 sulla cannuccia. The closure body 2 comprises an annular body wall 6 having a main axis X and a predefined height along said main axis X; the body wall 6 extends between a closure base 10 and an annular body wall edge 7 for the insertion of the closure body 2 on the straw.
La parete corpo 6 è filettata internamente (filettatura 14) per l’avvitamento alla cannuccia. The body wall 6 is internally threaded (thread 14) for screwing to the straw.
Il sovratappo 4 comprende un vano chiusura 16, ad esempio delimitato da una parete sovratappo 18 anulare, adatto ad accogliere almeno parzialmente il corpo chiusura 2. La parete sovratappo 18 si estende lungo detto asse principale X fra un bordo parete sovratappo 18a ed una base sovratappo 18b che fa da chiusura. The overlap 4 comprises a closure compartment 16, for example delimited by an annular overlap wall 18, suitable for at least partially accommodating the closure body 2. The overlap wall 18 extends along said main axis X between an overlap wall edge 18a and a base overlap 18b which acts as a closure.
Preferibilmente, il sovratappo 4 comprende una pluralità di alette 19, sporgenti radialmente esternamente dalla parete sovratappo 18, ed una parete di presa 20 anulare, continua o a tratti, resa solidale alla parete sovratappo 18 da dette alette. Preferably, the overcap 4 comprises a plurality of fins 19, protruding radially externally from the overlapping wall 18, and an annular gripping wall 20, continuous or in sections, made integral with the overlapping wall 18 by said fins.
In virtù delle alette 19, la parete di presa 20 è spaziata radialmente dalla parete sovratappo 18, formando passaggi 22 assiali anti-soffocamento. By virtue of the fins 19, the gripping wall 20 is radially spaced from the overlapping wall 18, forming axial anti-suffocation passages 22.
Preferibilmente, il corpo chiusura 2 è accolto nel vano chiusura 16 in modo da essere vincolato assialmente e in rotazione. Preferably, the closure body 2 is received in the closure compartment 16 so as to be axially constrained and in rotation.
Ad esempio, la parete corpo 6 del corpo chiusura 2 presenta una pluralità di costole 24 assiali sporgenti esternamente, mentre la parete sovratappo 18 presenta internamente una corrispondente pluralità di incavi 26 assiali, ciascun incavo essendo adatto ad accogliere la rispettiva costola, così realizzando un vincolo relativo in rotazione. For example, the body wall 6 of the closure body 2 has a plurality of axial ribs 24 projecting externally, while the overlapping wall 18 internally has a corresponding plurality of axial grooves 26, each groove being suitable for accommodating the respective rib, thus creating a constraint relative in rotation.
Inoltre, in prossimità della base chiusura 10, il corpo chiusura 2 comprende almeno un anellino 23 che si impegna nel vano chiusura 16, in prossimità di almeno una rispettiva scanalatura 25 prossima alla base sovratappo 18b per realizzare un vincolo relativo assiale. Furthermore, near the closing base 10, the closing body 2 comprises at least one ring 23 which engages in the closing compartment 16, near at least one respective groove 25 close to the overlapping base 18b to provide a relative axial constraint.
Un assieme cannuccia-chiusura 100, costituito da una cannuccia 110 per il sacchetto flessibile a pareti sottili, e dalla chiusura 1 sopra descritta, presenta una configurazione di impegno, in cui la chiusura è avvitata alla cannuccia, ed una configurazione di disimpegno, in cui la chiusura è svitata dalla cannuccia. Sono previsti mezzi di congiunzione adatti a mantenere la chiusura 1 collegata alla cannuccia anche nella configurazione di disimpegno, ossia dopo aver svitato la chiusura dalla cannuccia. A straw-closure assembly 100, consisting of a straw 110 for the flexible thin-walled bag, and the closure 1 described above, has an engagement configuration, in which the closure is screwed to the straw, and a disengagement configuration, in which the closure is unscrewed from the straw. Connection means are provided which are suitable for keeping the closure 1 connected to the straw also in the disengagement configuration, ie after having unscrewed the closure from the straw.
Secondo una forma di realizzazione, detti mezzi di congiunzione comprendono un collare 30 adatto ad essere inserito su un tratto di presa della cannuccia, ed un laccio 32 flessibile che collega il collare 30 al sovratappo 4, ad esempio alla parete sovratappo 18. According to an embodiment, said joining means comprise a collar 30 suitable to be inserted on a gripping portion of the straw, and a flexible lace 32 which connects the collar 30 to the overcap 4, for example to the overlap wall 18.
Il collare 30, tipicamente costituito da una parete anulare, ad esempio circolare, presenta un bordo inferiore 30a e un bordo superiore 30b adiacente al bordo parete sovratappo 18a della parete sovratappo 18 e collegato a questo tramite un sigillo di garanzia 30c rompibile. The collar 30, typically consisting of an annular wall, for example circular, has a lower edge 30a and an upper edge 30b adjacent to the edge of the overlapping wall 18a of the overlapping wall 18 and connected to this by means of a breakable security seal 30c.
Il collare 30 e la parete sovratappo 18 sono preferibilmente realizzati in un unico pezzo, ad esempio tramite stampaggio ad iniezione, in un primo materiale plastico, e sono collegati tramite il sigillo di garanzia 30c destinato ad essere rotto alla prima apertura della chiusura 1. The collar 30 and the overlapping wall 18 are preferably made in a single piece, for example by injection molding, in a first plastic material, and are connected by means of the guarantee seal 30c intended to be broken upon the first opening of the closure 1.
Il laccio 32 è realizzato in un secondo materiale plastico, più flessibile, diverso dal primo materiale plastico, tramite bi-iniezione, in un unico pezzo con la parete sovratappo 18 ed il collare 30. The lace 32 is made of a second plastic material, more flexible, different from the first plastic material, by means of bi-injection, in a single piece with the overlapping wall 18 and the collar 30.
Ad esempio, il laccio 32 ha forma di fascetta piatta. Secondo ulteriori forme di realizzazione, il laccio 32 presenta una sezione tonda o curvilinea, oppure poligonale, ad esempio quadrata o rettangolare, o mista curvilinea e rettilinea. For example, the lace 32 has the shape of a flat band. According to further embodiments, the lace 32 has a round or curvilinear, or polygonal section, for example square or rectangular, or a mixed curvilinear and rectilinear section.
Secondo una ulteriore forma di realizzazione, il laccio 32 presenta uno spessore costante dal collare 30 alla parete sovratappo 18; secondo ulteriori forme di realizzazione, lo spessore è variabile, ad esempio decrescente dalle estremità verso la regione centrale. Un processo di realizzazione secondo la presente invenzione, prevede di realizzare la parete sovratappo 18, il collare 30 ed il laccio 32 oppure l’intero sovratappo 4, il collare 30 ed il laccio 32 in un solo pezzo, in una configurazione chiusa corrispondente alla rappresentazione in figura 1. According to a further embodiment, the lace 32 has a constant thickness from the collar 30 to the overlapping wall 18; according to further embodiments, the thickness is variable, for example decreasing from the ends towards the central region. A manufacturing process according to the present invention provides for making the overlap wall 18, the collar 30 and the lace 32 or the entire overlap 4, the collar 30 and the tie 32 in one piece, in a closed configuration corresponding to the representation in figure 1.
Tramite bi-iniezione, il sovratappo 4 (o la parete sovratappo 18) e preferibilmente il collare 30 sono realizzati in un primo materiale plastico, ad esempio in polietilene (PE) o polipropilene (PP), che conferisce una certa rigidità, e il laccio 32 in un secondo materiale plastico, ad esempio più flessibile del primo, ad esempio in un elastomero termoplastico (TPE) o altro elastomero. By bi-injection, the overlap 4 (or the overlap wall 18) and preferably the collar 30 are made of a first plastic material, for example in polyethylene (PE) or polypropylene (PP), which gives a certain rigidity, and the lace 32 in a second plastic material, for example more flexible than the first, for example in a thermoplastic elastomer (TPE) or other elastomer.
Realizzati il sovratappo 4 con il collare 30 ed il laccio 32 e, separatamente, il corpo chiusura 2, quest’ultimo è inserito nel vano chiusura 16 del sovratappo 4, in modo che il bordo parete corpo 7 è deformato elasticamente e contenuto all’interno del collare 30. Preferibilmente, la cannuccia 110 comprende una porzione di collegamento 112, solitamente definita “barca di saldatura”, adatta ad essere saldata alle pareti sottili dell’imballo, e un tubetto 116 sporgente dalla porzione di collegamento 112 lungo un asse cannuccia Y, terminante con una imboccatura 118 della cannuccia 110. Once the overcap 4 has been made with the collar 30 and the lace 32 and, separately, the closure body 2, the latter is inserted in the closure compartment 16 of the overcap 4, so that the wall edge of the body 7 is elastically deformed and contained inside of the collar 30. Preferably, the straw 110 comprises a connecting portion 112, usually defined as a "welding boat", suitable for being welded to the thin walls of the package, and a tube 116 protruding from the connecting portion 112 along a straw axis Y , ending with a mouth 118 of the straw 110.
Lungo il tubetto 116, dalla porzione di collegamento 112 verso l’imboccatura 118, la cannuccia 110 comprende un tratto di presa 120 per l’impegno con il collare 30 dei mezzi di congiunzione. Along the tube 116, from the connecting portion 112 towards the mouth 118, the straw 110 comprises a gripping section 120 for engagement with the collar 30 of the joining means.
Ad esempio, detto tratto di presa 120 è delimitato da una piastra inferiore 122 ed un anello 124, preferibilmente smussato, per l’impegno con il collare 30. For example, said gripping section 120 is delimited by a lower plate 122 and a ring 124, preferably beveled, for engagement with the collar 30.
Il collare 30 è configurato per essere vincolato assialmente alla cannuccia 110, ed in particolare al tratto di presa 120. The collar 30 is configured to be axially constrained to the straw 110, and in particular to the gripping portion 120.
Ad esempio, il collare 30 comprende mezzi di ritegno assiale adatti a vincolare il collare 30 al tratto di presa 120. For example, the collar 30 comprises axial retaining means adapted to constrain the collar 30 to the gripping portion 120.
Ad esempio, detti mezzi di ritegno comprendono una porzione di impegno 31, sporgente assialmente dal bordo inferiore 30a, ripiegabile lungo detto bordo inferiore 30a, in modo da impegnarsi con l’anello 124 e formare un ostacolo allo sfilamento del collare 30 dal tratto di presa 120. For example, said retaining means comprise an engagement portion 31, axially projecting from the lower edge 30a, foldable along said lower edge 30a, so as to engage with the ring 124 and form an obstacle to the extraction of the collar 30 from the gripping portion 120.
Secondo una variante di realizzazione, il collare 30 è impegnabile a scatto con la cannuccia 110, per rimanere vincolato a questa. According to a variant embodiment, the collar 30 can be snap-engaged with the straw 110, in order to remain bound thereto.
Per la prima applicazione alla cannuccia, il processo prevede una prima fase in cui la chiusura 1 viene applicata alla cannuccia 110 e avvitata forzatamente a questa, in modo che il collare 30 si impegni con il tratto di presa 120 della cannuccia 110. For the first application to the straw, the process provides a first step in which the closure 1 is applied to the straw 110 and forcibly screwed thereto, so that the collar 30 engages with the gripping portion 120 of the straw 110.
Nel normale utilizzo dell’imballo, la chiusura 1 viene impugnata dall’utilizzatore e svitata dalla cannuccia; il collare 30 rimane impegnato con la cannuccia e, tramite il laccio 32, consente di mantenere il sovratappo collegato alla cannuccia. In normal use of the packaging, the closure 1 is gripped by the user and unscrewed from the straw; the collar 30 remains engaged with the straw and, by means of the lace 32, allows the overcap to be kept connected to the straw.
L’assieme costituito dal corpo chiusura 2, dal sovratappo 4, dalla cannuccia 110 e dal collare 30 realizza un sigillo di garanzia, la cui struttura e funzionalità è descritta nella Domanda Internazionale WO-A1-2018/020365 a nome della Richiedente. L’insegnamento in essa contenuto relativo a tale sigillo di garanzia è qui espressamente incorporato. The assembly consisting of the closure body 2, the overcap 4, the straw 110 and the collar 30 creates a guarantee seal, the structure and functionality of which is described in the International Application WO-A1-2018 / 020365 in the name of the Applicant. The teaching contained therein relating to this guarantee seal is expressly incorporated herein.
In particolare, secondo la Domanda Internazionale WO-A1-2018/020365, il collare 30 realizza la banda fissa del sigillo di garanzia, il bordo di base 7 del corpo chiusura 2 realizza l’anello di garanzia e la parete sovratappo 18 realizza il corpo mobile. In particular, according to the International Application WO-A1-2018 / 020365, the collar 30 forms the fixed band of the guarantee seal, the base edge 7 of the closure body 2 forms the guarantee ring and the overlap wall 18 forms the body mobile.
Durante lo svitamento della chiusura, il sigillo di garanzia 30c va incontro a rottura poiché il collare 30 è vincolato alla cannuccia, mentre la parete sovratappo 18 ed il corpo chiusura 2 tendono a separarsi assialmente dalla cannuccia a causa dello svitamento. During the unscrewing of the closure, the guarantee seal 30c undergoes breakage since the collar 30 is bound to the straw, while the overlapping wall 18 and the closure body 2 tend to separate axially from the straw due to the unscrewing.
Conseguentemente, il bordo parete corpo 7 del corpo chiusura 4 fuoriesce dal collare 30 e tende a ritornare nella condizione indeformata, allargandosi verso l’esterno. Consequently, the edge of the body wall 7 of the closure body 4 protrudes from the collar 30 and tends to return to the undeformed condition, widening outwards.
In tal modo, riavvitando la parete sovratappo 18 provvista del corpo chiusura 2 alla cannuccia, il bordo parete corpo 7 si frappone fra il bordo parete sovratappo 18a ed il collare 30, impedendone il contatto reciproco, così evidenziando l’avvenuta prima apertura dell’imballo. In this way, by screwing back the overlapping wall 18 provided with the closure body 2 to the straw, the body wall edge 7 is interposed between the overlapping wall edge 18a and the collar 30, preventing mutual contact, thus highlighting the first opening of the packaging. .
Innovativamente, la chiusura secondo la presente invenzione consente di soddisfare le esigenze de settore e di superare gli inconvenienti di cui si è detto, in quanto la chiusura rimane collegata alla cannuccia anche dopo l’apertura dell’imballo. Innovatively, the closure according to the present invention allows to meet the needs of the sector and to overcome the aforementioned drawbacks, as the closure remains connected to the straw even after the packaging has been opened.
Vantaggiosamente, inoltre, la chiusura secondo la presente invenzione è ottenuta dallo stampaggio nella condizione in cui il collare è allineato con la parete sovratappo, ossia già nella condizione che consente l’applicazione del corpo chiusura e l’avvitamento alla cannuccia. Ciò in virtù della bi-iniezione del laccio con il collare e il sovratappo. Advantageously, moreover, the closure according to the present invention is obtained by molding in the condition in which the collar is aligned with the overlapping wall, ie already in the condition that allows the application of the closure body and screwing to the straw. This is due to the bi-injection of the lace with the collar and the overcap.
E’ chiaro che un tecnico del ramo, al fine di soddisfare esigenze contingenti e specifiche, potrebbe apportare modifiche alla chiusura sopra descritta. It is clear that a person skilled in the art, in order to meet contingent and specific needs, could make changes to the closure described above.
La variante di realizzazione sopra descritta, in cui la chiusura prevede un corpo chiusura, il sovratappo è indirettamente applicato alla cannuccia. The variant embodiment described above, in which the closure provides a closure body, the overcap is indirectly applied to the straw.
Secondo una variante di realizzazione, in cui la chiusura è priva del corpo di chiusura, il sovratappo direttamente applicato alla cannuccia ed utilizzato per chiuderla. Anche tale variante di realizzazione è contenuta nell’ambito di tutela come definito dalle rivendicazioni seguenti. According to a variant embodiment, in which the closure is without the closure body, the overcap is directly applied to the straw and used to close it. This variant of construction is also contained within the scope of protection as defined by the following claims.
