Description
Descrizione Description
Il presente trovato si riferisce a un dispositivo erogatore di sostanze fluide. The present invention relates to a device for dispensing fluid substances.
In particolare si riferisce a un dispositivo erogatore a fondello mobile con erogazione a pompa, che permette al fluido da erogare di rimanere isolato dall’aria circostante fino al momento dell’erogazione, evitando cosi contaminazioni dello stesso. In particular, it refers to a dispensing device with a movable bottom with pump dispensing, which allows the fluid to be dispensed to remain isolated from the surrounding air until the moment of dispensing, thus avoiding contamination of the same.
Sono noti dei contenitori con fondello mobile che solitamente vengono associati ad una pompa ermetica. La particolarità della pompa ermetica à ̈ quella di erogare il prodotto non permettendo dell’ingresso di aria all’interno del contenitore. In pratica le pompe ermetiche non presentano passaggi per effettuare il così detto †̃venting’. Il risultato à ̈ che ad ogni erogazione di prodotto il contenitore viene posto in depressione. Ciò provoca l’innalzamento del fondello e la conseguente diminuzione del volume dedicato all’alloggiamento del fluido da erogare che via via diminuisce dopo ogni erogazione. Containers with movable bottoms are known which are usually associated with a hermetic pump. The peculiarity of the hermetic pump is to dispense the product not allowing air to enter the container. In practice, hermetic pumps do not have steps to carry out the so-called â € ̃ventingâ € ™. The result is that each time the product is dispensed, the container is placed under depression. This causes the pad to rise and the consequent decrease in the volume dedicated to housing the fluid to be dispensed, which gradually decreases after each dispensing.
Un inconveniente che si rileva in tali tipi di dispositivi à ̈ che, una volta riempiti di fluido da erogare e chiusi, può rimanere presente nel contenitore dell’aria. Tale aria può provocare delle discontinuità di erogazione. A drawback that is noted in these types of devices is that, once filled with the fluid to be dispensed and closed, it can remain present in the air container. This air can cause discontinuity of supply.
Un ulteriore inconveniente derivante dalla presenza di aria nel contenitore può essere l’eventuale incompatibilità di quest’ultima con il prodotto contenuto nel dispositivo. Si pensi ad esempio a creme che possano seccare oppure a altri prodotti che si possono alterare al contatto con l’aria. A further drawback deriving from the presence of air in the container may be the eventual incompatibility of the latter with the product contained in the device. For example, think of creams that can dry out or other products that can be altered in contact with air.
Per ovviare a tale inconveniente si à ̈ pensato di eseguire la chiusura del contenitore sotto vuoto. In altre parole il contenitore viene riempito di fluido da erogare e tappato tramite un elemento di chiusura in cui à ̈ innestata la pompa, in un ambiente interamente in depressione. Questo crea notevoli complicazioni tecniche derivanti dalla necessità di creare una zona in depressione con le conseguenti problematiche di alti costi e basse velocità di lavorazione. To overcome this problem, it was decided to close the container under vacuum. In other words, the container is filled with the fluid to be dispensed and capped by means of a closure element in which the pump is inserted, in an environment entirely in depression. This creates considerable technical complications deriving from the need to create a depression area with the consequent problems of high costs and low processing speeds.
Scopo della presente innovazione à ̈ quello di semplificare rendendo meno complesse, meno costose e più veloci le operazioni legate alla chiusura di dispositivi ermetici a fondello mobile. The purpose of this innovation is to simplify, making the operations related to the closure of hermetic devices with movable bottom less complex, less expensive and faster.
Questo ed altri scopi vengono raggiunti da un dispositivo e metodo realizzati secondo gli insegnamenti tecnici delle annesse rivendicazioni. This and other purposes are achieved by a device and method realized according to the technical teachings of the attached claims.
Ulteriori caratteristiche e vantaggi del trovato risulteranno evidenti dalla descrizione di una forma di realizzazione preferita ma non esclusiva del dispositivo e metodo, illustrata a titolo esemplificativo e quindi non limitativo nei disegni allegati, in cui: Further characteristics and advantages of the invention will become evident from the description of a preferred but not exclusive embodiment of the device and method, illustrated by way of example and therefore not of limitation in the attached drawings, in which:
la figura 1 Ã ̈ una sezione del dispositivo della seguente invenzione in configurazione di utilizzo; Figure 1 is a section of the device of the following invention in the configuration of use;
la figura 2 Ã ̈ una vista in sezione ingrandita di un dettaglio del dispositivo di figura 1 durante una prima fase della sua chiusura; Figure 2 is an enlarged sectional view of a detail of the device of Figure 1 during a first phase of its closure;
la figura 3 Ã ̈ una vista in sezione ingrandita di un dettaglio del dispositivo di figura 1 durante una seconda fase della sua chiusura; Figure 3 is an enlarged sectional view of a detail of the device of Figure 1 during a second phase of its closure;
la figura 4 e la figura 5 mostrano forme alternative di realizzazione dell’elemento di comressione. Figure 4 and Figure 5 show alternative embodiments of the compression element.
Con riferimento alle figure citate, viene mostrato un dispositivo di erogazione indicato con il numero di riferimento 1. With reference to the aforementioned figures, a dispensing device indicated with the reference number 1 is shown.
Il dispositivo 1 comprende un contenitore 2 che presenta un fondo mobile 3 scorrevole a tenuta all’interno dello stesso. Sul fondo del contenitore à ̈ presente un passaggio d’aria 4 che consente un ingresso di aria nella zona 5 sottostante il fondello. The device 1 comprises a container 2 which has a movable bottom 3 that can slide tightly inside it. On the bottom of the container there is an air passage 4 which allows air to enter the area 5 below the bottom.
Il dispositivo 1 presenta inoltre una ghiera 6 a cui à ̈ vincolata a scatto una pompa ermetica 7 azionabile a mano. La pompa ermetica à ̈ del tipo convenzionale e non verrà in seguito descritta. La pompa à ̈ fissata e a tenuta con la ghiera 6, in modo del tutto convenzionale. Il complesso ghiera/pompa forma un elemento di chiusura per il contenitore 2. The device 1 also has a ring nut 6 to which a hand-operated hermetic pump 7 is snap-coupled. The hermetic pump is of the conventional type and will not be described below. The pump is fixed and sealed with the ring nut 6, in a completely conventional way. The nut / pump assembly forms a closure element for the container 2.
Il contenitore 2 à ̈ inserito a scatto in un rivestimento 8 al quale à ̈ fissato anche tramite la ghiera 6. In particolare la ghiera 6 presenta un incavo 6A che coopera a scatto e a sottosquadro con un dente anulare 8A ricavato sul rivestimento 8. Il contenitore 1 presenta una superficie conica 2A che va in battuta contro uno spigolo 8b del rivestimento 8. Alla sommità del contenitore 1, à ̈ poggiata una flangia 9A di un elemento di compressione 9; la flangia a contenitore chiuso à ̈ compressa fra un gradino 6C della ghiera e il contenitore 1 stesso e rimane cosi bloccata. The container 2 is snap-inserted into a coating 8 to which it is also fixed by means of the ring 6. In particular, the ring 6 has a recess 6A which cooperates by snap and undercut with an annular tooth 8A obtained on the lining 8. The container 1 has a conical surface 2A which abuts against an edge 8b of the covering 8. At the top of the container 1, a flange 9A of a compression element 9 rests; the closed container flange is compressed between a step 6C of the ring nut and the container 1 itself and thus remains locked.
Dalla flangia 9A dell’elemento di compressione 9 si diparte una prima parete cilindrica 9B che à ̈ collegata da un gradino 9C ad una seconda parete cilindrica 9E che presenta sulla sua superficie esterna un bordino 10 sporgente che funge da elemento di tenuta cooperando con la superficie interna del contenitore 1. A first cylindrical wall 9B departs from the flange 9A of the compression element 9 and is connected by a step 9C to a second cylindrical wall 9E which has a protruding rim 10 on its external surface which acts as a sealing element cooperating with the inner surface of the container 1.
Dalla seconda parete 9E si estende una parete conica 11 che connette tramite una porzione deformabile 12 detta parete a una porzione discoidale 13 da cui si estende una superficie tronconica 14 divergente verso l’interno del contenitore. A conical wall 11 extends from the second wall 9E which connects said wall through a deformable portion 12 to a discoidal portion 13 from which extends a truncated surface 14 diverging towards the inside of the container.
La porzione deformabile presenta in sezione uno spessore inferiore rispetto al resto dell’elemento di compressione 9 che le permette quindi di deformarsi in modo tale da pre-caricare il fluido interno al contenitore. L’elemento di compressione 9 presenta un elemento valvolare unidirezionale che permette l’espulsione dell’aria presente al di sopra del fluido durante la chiusura del contenitore. The deformable portion has a smaller section in section than the rest of the compression element 9 which therefore allows it to deform in such a way as to pre-load the fluid inside the container. The compression element 9 has a unidirectional valve element which allows the expulsion of the air present above the fluid during the closing of the container.
Poco sopra à ̈ stata descritta una forma di realizzazione esemplificativa della porzione deformabile 12 che in sostanza deve deformarsi per esercitare una pressione sul fluido inserito nel contenitore in modo da favorire l’espulsione di eventuale aria presente all’interno dello stesso. A little above an exemplary embodiment of the deformable portion 12 has been described which in substance must deform to exert a pressure on the fluid inserted in the container so as to favor the expulsion of any air present inside it.
Certamente potranno essere previste ulteriori forme di realizzazione della porzione deformabile che potrà essere realizzata in qualsivoglia forma adatta allo scopo. Le figure 4 e 5 mostrano ad esempio altre forme di realizzazione dell’elemento di compressione che qui verrà indicato con i riferimenti numerici 90, 91. Nella figura 4 la porzione deformabile 120 viene realizzata mediante un rigonfiamento verso l’esterno della parete che risulta solo di poco più sottile rispetto al resto delle pareti dell’elemento. Ciò migliora la cedevolezza della porzione deformabile che data la sua forma rigonfia tende a †̃cedere’ prima delle altre. Certainly, further embodiments of the deformable portion can be provided, which can be made in any form suitable for the purpose. Figures 4 and 5 show for example other embodiments of the compression element which will be indicated here with the numerical references 90, 91. In figure 4 the deformable portion 120 is made by means of an outward swelling of the wall which it is only slightly thinner than the rest of the element walls. This improves the compliance of the deformable portion which, due to its swollen shape, tends to "yield" before the others.
Nella figura 5 viene mostrato l’elemento di compressione 91 che presenta come nella forma di realizzazione precedente un rigonfiamento verso l’esterno. In questo caso però in corrispondenza del rigonfiamento 121 si nota un maggiore assottigliamento della parete che certamente ne avvantaggia la deformazione. Figure 5 shows the compression element 91 which has an outward swelling as in the previous embodiment. In this case, however, in correspondence with the swelling 121 there is a greater thinning of the wall which certainly benefits the deformation.
Come ribadito sono state illustrate tre forme esemplificative di come potrà essere realizzata la porzione deformabile, ma ne potranno essere concepite altre; ad esempio la porzione deformabile potrebbe essere realizzata a soffietto oppure à ̈ possibile selezionare per la realizzazione dell’elemento di compressione una materiale sufficientemente elastico da rendere superfluo prevedere una zona dedicata alla deformazione. In tal caso sarebbe il complesso dell’elemento elastico a deformarsi in più punti comprimendo il fluido nella misura desiderata. As reiterated, three exemplary forms of how the deformable portion can be made have been illustrated, but others can be conceived; for example, the deformable portion could be made of a bellows or it is possible to select for the realization of the compression element a material sufficiently elastic to make it unnecessary to provide a zone dedicated to the deformation. In this case, the complex of the elastic element would be deformed in several points, compressing the fluid to the desired extent.
L’elemento valvolare 15 può essere realizzato in svariati modi ovvi per il tecnico del ramo, ma nella presente forma di realizzazione esso à ̈ realizzato tramite una superficie di interfaccia elasticamente deformabile ricavata alla sommità della porzione troncoconica che viene calzata sul corpo a bicchiere della pompa. In particolare la porzione troncoconica 14 à ̈ calzata sulla porzione del corpo a bicchiere a raggio maggiore, ovvero nella zona del corpo a bicchiere all’interno della quale scorre lo stelo. Ciò consente di effettuare la tenuta fra elemento di compressione e pompa su un diametro maggiore, sfruttando al meglio le proprietà elastiche del materiale con cui à ̈ realizzato l’elemento di compressione. In particolare e preferibilemente quest’ultimo à ̈ realizzato per stampaggio a iniezione di materia plastica come ad esempio PP – PE - Termoplastici caricati gomma, Elastomeri. The valve element 15 can be made in various ways that are obvious to the person skilled in the art, but in the present embodiment it is made by means of an elastically deformable interface surface obtained at the top of the truncated cone portion which is fitted onto the cup body of the pump. In particular, the truncated cone portion 14 is fitted on the portion of the cup-shaped body with a greater radius, ie in the area of the cup-shaped body inside which the stem slides. This allows sealing between the compression element and the pump on a larger diameter, making the most of the elastic properties of the material with which the compression element is made. In particular and preferably the latter is made by injection molding of plastic material such as PP - PE - Rubber filled thermoplastics, Elastomers.
Vantaggiosamente il complesso determinato dall’elemento di compressione e del fondo della pompa presenta una conformazione sostanzialmente complementare a quella del fondello mobile, in modo da poter massimizzare la quantità di prodotto erogato riducendo al minimo gli spazi fra fondello e pompa/elemento di compressione. Advantageously, the assembly determined by the compression element and the bottom of the pump has a conformation substantially complementary to that of the movable bottom, so as to be able to maximize the quantity of product dispensed by minimizing the spaces between the bottom and the pump / compression element.
A completamento della descrizione del trovato si sottolinea che l’elemento di compressione fa tenuta sul contenitore 2 mentre fra il rivestimento 8 e il contenitore à ̈ previsto un aggancio a scatto tramite un dente 2A che si impegna in uno scasso previsto nel rivestimento 8. In corrispondenza della porzione in cui avviene l’aggancio a scatto sono poi previsti dei passaggi d’aria 16 per alimentare la zona 5 presente al di sotto del fondello mobile. To complete the description of the invention, it is emphasized that the compression element makes a seal on the container 2 while a snap coupling is provided between the lining 8 and the container by means of a tooth 2A which engages in a recess provided in the lining 8. In correspondence with the portion in which the snap coupling takes place, air passages 16 are then provided to feed the area 5 present under the movable bottom.
Il funzionamento del trovato à ̈ sostanzialmente il seguente. The operation of the invention is substantially the following.
Il contenitore 2 viene riempito del fluido 20 da erogare. Per esempio tale prodotto può essere tale per cui la presenza di aria può compromettere la stabilità dello stesso , come ad esempio creme, fondotinta, gel ecc. The container 2 is filled with the fluid 20 to be dispensed. For example, this product can be such that the presence of air can compromise its stability, such as creams, foundations, gels, etc.
Successivamente lo stesso viene chiuso applicando sullo stesso il complesso ghiera 6, pompa 7 e elemento di compressione 9. In particolare l’elemento di compressione e la pompa affondano parzialmente nel fluido causandone l’innalzamento del livello all’interno del contenitore. Come visibile in figura 2 in una prima fase l’aria presente al di sopra del fluido (fra il fluido e l’elemento di compressione 9) viene sfogata attraverso un passaggio 21 che viene a crearsi fra la parete 9E dell’elemento di compressione 9. Tale passaggio rimane aperto fintanto che l’elemento di tenuta 10 resta staccato dalla parete interna del contenitore 1. Subsequently, it is closed by applying the ring nut 6, pump 7 and compression element 9 on it. In particular, the compression element and the pump partially sink into the fluid causing the level inside the container to rise. As shown in figure 2, in a first phase the air present above the fluid (between the fluid and the compression element 9) is vented through a passage 21 which is created between the wall 9E of the element compression 9. This passage remains open as long as the sealing element 10 remains detached from the internal wall of the container 1.
Non appena il bordino 10 viene a far tenuta sul contenitore 1, l’aria presente nell’intercapedine 22 fra corpo pompa e elemento di compressione inizia a comprimersi sia per l’abbassamento dell’elemento di chiusura, sia per il conseguente innalzamento del fluido interno al contenitore. Raggiunta una determinata pressione all’interno del contenitore la superficie di interfaccia elasticamente deformabile dell’elemento di compressione 9 si deforma e apre un passaggio 23 radente alla superficie della pompa che permette lo sfogo dell’aria residua al di sopra del fluido. Lo stesso risultato sopra descritto può essere ottenuto tramite un qualsivoglia elemento valvolare adatto allo scopo. Terminato lo sfogo dell’aria e raggiunta la posizione di chiusura del dispositivo l’interfaccia elasticamente deformabile torna elasticamente a far tenuta sul corpo a bicchiere, impedendo così l’ingresso di aria all’interno del contenitore. As soon as the lip 10 is sealed on the container 1, the air present in the gap 22 between the pump body and the compression element begins to compress both due to the lowering of the closing element and the consequent raising of the fluid inside the container. Once a certain pressure has been reached inside the container, the elastically deformable interface surface of the compression element 9 deforms and opens a passage 23 grazing the surface of the pump which allows the residual air to escape above the fluid. The same result described above can be obtained by means of any valve element suitable for the purpose. Once the air has been vented and the device has reached the closed position, the elastically deformable interface resists elastically to seal the cup body, thus preventing the entry of air into the container.
Vantaggiosamente la porzione deformabile, comunque essa sia realizzata, permette di precomprimere leggermente il fluido contenuto internamente al contenitore minimizzando cosi la quantità di aria eventualmente imprigionata all’interno dello stesso. Advantageously, the deformable portion, however it is made, allows the fluid contained inside the container to be slightly pre-compressed, thus minimizing the amount of air eventually trapped inside it.
Certamente durante la fase di chiusura à ̈ possibile che terminata l’espulsione dell’aria, fuoriesca anche una piccola quantità di fluido dall’elemento valvolare 15. Ciò garantisce che non à ̈ più presente aria all’interno del contenitore 1. L’eventuale fluido fuoriuscito si deposita nel compartimento 24 che à ̈ isolato dall’esterno. Certainly during the closing phase it is possible that once the air has been expelled, even a small amount of fluid may escape from the valve element 15. This guarantees that there is no longer any air inside the container 1 Any leaked fluid is deposited in compartment 24 which is isolated from the outside.
Pertanto esso non crea alcun tipo di problema, nemmeno nel momento in cui il contenitore viene rovesciato. Therefore it does not create any kind of problem, even when the container is overturned.
E’stata descritta una forma preferita di realizzazione ma altre potranno essere concepite sfruttando lo stesso concetto innovativo. A preferred embodiment has been described but others may be conceived by exploiting the same innovative concept.
