DESCRIZIONE DESCRIPTION
Annessa a domanda di BREVETTO DI INVENZIONE avente per titolo “Contenitore plastico per materiale a cambiamento di fase (phase change material) avente comportamento microbicida, battericida, sporicida e fungicida" Attached to the application for an INVENTION PATENT entitled â € œPlastic container for phase change material having microbicidal, bactericidal, sporicidal and fungicidal behavior "
La presente invenzione ha per oggetto un contenitore plastico per materiale a cambiamento di fase (phase change material) avente comportamento microbicida, battericida, sporicida e fungicida. The present invention relates to a plastic container for phase change material having microbicidal, bactericidal, sporicidal and fungicidal behavior.
Materiali a cambiamento di fase (phase change material), generalmente prodotti refrigeranti, vengono utilizzati in tutti quei settori dove sia necessario controllare la temperatura interna di un alloggiamento adibito al trasporto di prodotti deperibili, quali medicinali o alimenti. Phase change materials, generally refrigerant products, are used in all those sectors where it is necessary to control the internal temperature of a housing used for the transport of perishable products, such as medicines or food.
I materiali a cambiamento di fase sono di solito presentati in un contenitore morbido oppure in un contenitore rigido. Il contenitore morbido à ̈ fatto con un film di polietilene, polipropilene, nylon o altri polimeri avente una buona resistenza meccanica ed allo stesso tempo la flessibilità necessaria al loro utilizzo. Il contenitore rigido à ̈ in materiale plastico a forma di parallelepipedo o simile, di solito realizzato in polietilene, polipropilene, nylon o altra plastica a seconda delle caratteristiche meccaniche richieste dall’applicazione. Phase change materials are usually presented in a soft container or a rigid container. The soft container is made with a film of polyethylene, polypropylene, nylon or other polymers having a good mechanical resistance and at the same time the flexibility necessary for their use. The rigid container is made of parallelepiped-shaped plastic material or similar, usually made of polyethylene, polypropylene, nylon or other plastic depending on the mechanical characteristics required by the application.
Il materiale a cambiamento di fase così contenuto viene di solito raffreddato o riscaldato in maniera tale da superare la temperatura di passaggio di stato e viene, quindi, utilizzato per raffreddare o riscaldare un oggetto o l’interno di un alloggiamento isotermico ad una temperatura desiderata che si trova, rispettivamente, ad un valore superiore o inferiore alla temperatura di passaggio di stato del materiale a cambiamento di fase stesso. The phase change material thus contained is usually cooled or heated in such a way as to exceed the transition temperature and is then used to cool or heat an object or the interior of an isothermal housing to a temperature which is, respectively, at a value higher or lower than the transition temperature of the phase change material itself.
In alcuni casi l’utilizzo di tali prodotti refrigeranti comporta degli inconvenienti. Ad esempio, in alloggiamenti isotermici nel trasporto di medicinali o derrate alimentari che debbano essere conservate a temperature comprese generalmente tra 2°C e 8°C, si osserva che a tali temperature uno strato di rugiada, dovuto alla condensazione del vapore acqueo atmosferico, à ̈ solito formarsi sulle superfici esterne del contenitore di materiale a cambiamento di fase. Il permanere di tale rugiada sulle superfici per tutto il tempo necessario al trasporto dei medicinali o delle derrate, può provocare una proliferazione di microbi, batteri, spore, funghi. Tale problematica si presenta in maniera assolutamente critica e richiede una soluzione adeguata all’utilizzo stesso. La concentrazione di batteri, microbi, muffe, spore e funghi che si forma sulla superficie esterna bagnata delle confezioni di materiale a cambiamento di fase dipende ovviamente da quanto à ̈ inquinato l’ambiente circostante o da quanto sono inquinati i dispositivi raramente sterilizzati (come i guanti, le superfici di lavoro, i carrelli, ecc ) utilizzati nelle varie fasi di lavorazione e trasporto. Diverse misurazioni delle concentrazioni suddette, effettuate sul campo, hanno determinato una criticità dei valori assolutamente non trascurabile. In some cases, the use of these refrigerant products involves drawbacks. For example, in isothermal housings in the transport of medicines or foodstuffs that must be stored at temperatures generally between 2 ° C and 8 ° C, it is observed that at these temperatures a layer of dew, due to the condensation of atmospheric water vapor, It usually forms on the outer surfaces of the phase change material container. The persistence of this dew on the surfaces for all the time necessary for the transport of medicines or foodstuffs, can cause a proliferation of microbes, bacteria, spores and fungi. This problem presents itself in an absolutely critical way and requires an adequate solution for the use itself. The concentration of bacteria, microbes, molds, spores and fungi that forms on the wet outer surface of the phase change material packs obviously depends on how polluted the surrounding environment is or how polluted the rarely sterilized devices are (such as gloves, work surfaces, trolleys, etc.) used in the various stages of processing and transport. Various measurements of the aforementioned concentrations, carried out in the field, have determined an absolutely not negligible criticality of the values.
Scopo della presente invenzione à ̈ quello di evitare la proliferazione di microbi, batteri, spore, funghi sulla superficie di contenitori di materiale a cambiamento di fase. The purpose of the present invention is to avoid the proliferation of microbes, bacteria, spores, fungi on the surface of containers of phase change material.
Lo scopo viene raggiunto da un contenitore plastico atto ad impedire la proliferazione di microbi, batteri, funghi, muffe e spore mediante la presenza di ioni argento inclusi nel contenitore per materiale a cambiamento di fase ed aventi un elevato potere di catadinizzazione. The purpose is achieved by a plastic container suitable for preventing the proliferation of microbes, bacteria, fungi, molds and spores by means of the presence of silver ions included in the container for phase change material and having a high catadinization power.
Tre note metodologie possono essere usate per ottenere tale presenza: Three known methodologies can be used to achieve this presence:
i) applicazione sulla superficie esterna del contenitore plastico per materiale a cambiamento di fase di una vernice contenente ioni di argento. Tale vernice può ricoprire totalmente o parzialmente la superficie esterna del contenitore in maniera tale da realizzare una protezione della superficie più o meno elevata; i) application on the external surface of the plastic container for phase change material of a paint containing silver ions. This paint can totally or partially cover the external surface of the container in such a way as to achieve a more or less high surface protection;
ii) miscelazione di ioni di argento nel polimero utilizzato per la produzione del film o del materiale plastico che costituiscono il contenitore; ii) mixing of silver ions in the polymer used for the production of the film or plastic material that make up the container;
iii) deposizione sottovuoto di ioni di argento allo stato di plasma sulla superficie esterna del contenitore plastico per materiale a cambiamento di fase. iii) vacuum deposition of plasma state silver ions on the outer surface of the plastic container for phase change material.
Le caratteristiche dell’invenzione sono esposte nella rivendicazione 1 e nelle rivendicazioni da essa dipendenti. The characteristics of the invention are set forth in claim 1 and in the claims dependent on it.
Scopi e vantaggi della presente invenzione verranno meglio compresi nel seguito con riferimento ad alcune sue forme di realizzazione mostrate negli uniti disegni in cui: Objects and advantages of the present invention will be better understood in the following with reference to some of its embodiments shown in the accompanying drawings in which:
la figura 1 Ã ̈ una vista laterale di un contenitore morbido per materiale a cambiamento di fase; Figure 1 is a side view of a soft container for phase change material;
la figura 2 Ã ̈ una vista in pianta del contenitore morbido della figura 1; Figure 2 is a plan view of the soft container of Figure 1;
la figura 3 Ã ̈ una vista in pianta di un contenitore rigido per materiale a cambiamento di fase; Figure 3 is a plan view of a rigid container for phase change material;
la figura 4 à ̈ una vista di estremità destra del contenitore rigido della figura 3; e la figura 5 à ̈ una vista laterale del contenitore rigido della figura 3. Figure 4 is a right-hand end view of the rigid container of Figure 3; and Figure 5 is a side view of the rigid container of Figure 3.
Facendo riferimento alle figure 1 e 2, che sono una vista laterale e, rispettivamente, una vista in pianta di un contenitore morbido per materiale a cambiamento di fase, il contenitore plastico à ̈ indicato con 1, opportunamente sigillato con saldature 12 di estremità per contenere un materiale a cambiamento di fase indicato con 2. Il contenitore plastico morbido 1 à ̈ di forma convenzionale ma, secondo l’invenzione, la materia plastica flessibile del contenitore plastico morbido 1 include ioni argento, che sono incorporati nella materia plastica stessa, contenuti in una vernice applicata sulla superficie esterna oppure presenti sulla superficie esterna del contenitore plastico morbido 1 a mezzo di deposizione sottovuoto al plasma. With reference to Figures 1 and 2, which are a side view and, respectively, a plan view of a soft container for phase change material, the plastic container is indicated with 1, suitably sealed with end welds 12 to contain a phase change material indicated with 2. The soft plastic container 1 is of conventional shape but, according to the invention, the flexible plastic material of the soft plastic container 1 includes silver ions, which are incorporated in the plastic material itself, contained in a paint applied on the external surface or present on the external surface of the soft plastic container 1 by means of plasma vacuum deposition.
Facendo ora riferimento alle figure 3 a 5, che sono una vista in pianta, una vista di estremità e, rispettivamente, una vista laterale di un contenitore plastico rigido per materiale a cambiamento di fase, il contenitore rigido, di forma sostanzialmente parallelepipeda, à ̈ indicato con 3; esso à ̈ opportunamente sigillato con un tappo 4 per contenere un materiale a cambiamento di fase indicato con 2. Il contenitore plastico rigido 3 à ̈ di forma convenzionale ma, secondo l’invenzione, la materia plastica rigida del contenitore plastico rigido 3 include ioni argento, che sono incorporati nella materia plastica stessa, contenuti in una vernice applicata sulla superficie esterna oppure presenti sulla superficie esterna del contenitore plastico rigido 3 a mezzo di deposizione sottovuoto al plasma. Referring now to figures 3 to 5, which are a plan view, an end view and, respectively, a side view of a rigid plastic container for phase change material, the rigid container, substantially parallelepiped in shape, is indicated with 3; it is suitably sealed with a cap 4 to contain a phase change material indicated by 2. The rigid plastic container 3 is of conventional shape but, according to the invention, the rigid plastic material of the rigid plastic container 3 includes ions silver, which are incorporated in the plastic material itself, contained in a paint applied to the external surface or present on the external surface of the rigid plastic container 3 by means of plasma vacuum deposition.
Tutte le soluzioni sono adeguate e realizzano una presenza di ioni argento nel contenitore tale da ottenere un comportamento microbicida, eliminando il possibile rischio di presenza di microbi, batteri, funghi, muffe e spore sulla superficie esterna del contenitore. Ciò avviene di solito in ambiente umido, ma anche in assenza di umidità condensata sulla superficie dei contenitori sopra descritti, si riscontra spesso una concentrazione di batteri , microbi, muffe, spore e funghi al di sopra dei valori accettabili per l’utilizzo, presenza dovuta dal contatto di detti contenitori con guanti, superfici di lavoro, carrelli, ecc , generalmente non sterilizzati. L’effetto della catanidizzazione riesce ad ovviare anche a questi inconvenienti. All the solutions are adequate and realize a presence of silver ions in the container such as to obtain a microbicidal behavior, eliminating the possible risk of the presence of microbes, bacteria, fungi, molds and spores on the external surface of the container. This usually occurs in a humid environment, but even in the absence of condensed humidity on the surface of the containers described above, there is often a concentration of bacteria, microbes, molds, spores and fungi above the acceptable values for use, presence due to the contact of said containers with gloves, work surfaces, trolleys, etc., generally not sterilized. The effect of the catanidization is also able to obviate these drawbacks.
