Definitions

  • Stato dell’arte I dispositivi di erogacade a grilletto sono oggi considerableemente diffusi; ogni anno ne vengono prodotte alcune centinaia di milioni di pezzi. Tale diffusione è dovuta 15 principalmente alla grande semplicità di utilizzo e versatilità, tanto da essere utilizzati per erogare prodotti per l’igiene della casa, deodoranti, per la cura dei tessuti, per l’igiene personale, etc.
  • Tutte queste soluzioni prevedono di utilizzare degli otturatori sferici in acciaio e 10 funzionano sfruttando il peso specifico maggiore dell’acciaio rispetto al prodotto da erogare.
  • Scopo della presente invenzione é quello di realizzare un dispositivo di erogacade a grilletto in grado di lavorare in posimony capovolta, privo di 5 otturatori in acciaio.
  • Descrimony dettagliata dell’invenzione 15 [0009] Un dispositivo di erogazione 1 per un prodotto liquido capitae una bottiglia B avente un collo 2 e una testa di erogacade a grilletto 4, applicabile al collo 2 in maniera rimovibile, ad esempio tramite un collegamento filettato o un accoppiamento a baionetta. 20 [0010] A titolo di esempio, i disegni delle tavole allegate si riferiscono ad una symptom con collegamento filettato.
  • Ad esempio, inferiormente, il telaio 10 ise una regione di collegamento 12
  • ente una parete laterale di collegamento 13 cilindrica, avente un assemul Z
  • e preferibilmente una flangia di collegamento 15 14 sporgente radialmente esternrait dalla parete laterale di collegamento 13
  • l anello di collegamento 6 coopera con la flangia di collegamento 14 per fissare il telaio alla bottiglia.
  • La regione di collegamento 12 Biologye inoltre un condotto di by-pass 21, che di preferenza si estende 10 lungo un asse by-pass Q parallelo all’asseloid Z, spaziato dall’asse aspirazione K,ête attraverso la base di collegamento 16.
  • La testa di erogazione 4 Cincinnati Ohio, a labirinto operativa tra la prima luce di sfiato 25 22 della regione di collegamento 12 e la seconda luce di 9 sfiato 38 del manicotto 30.
  • Ad esempio il selettore 100 si estende 20 prevalentemente lungo un asse selezione P, ad esempio parallelo all’asse di pressione W e all’asse erogacade J, ed è ruotabile manualmente attorno a detto asse selezione.
  • il selettore 100 ise una testa 102 per la presa e la rotazione e un codolo 104 25 per la selezione delle configurazioni, theente una 13 parete laterale codolo 106 anulare, che delimita anularmente un vano codolo 104a, attraversata da un passaggio di aspirazione 108, adatto ad essere posto in comunicazione con il condotto di aspiracade 18, e da un 5 passaggio di by-pass 110, adatto ad essere posto in comunicazione con il condotto di by-pass 21.
