Claim 1
Independent Claim
150 words
A METHOD OF ASSEMBLYING A VALVE IN AN INFLATABLE HOLLOW ARTICLE COMPRISING THE STEPS OF FORMING A PLASTIC VALVE RETAINER HAVING AN AXIALLY EXTENDING BORE THEREIN AND HAVING A BASE FLANGE, WHICH BORE HAS AN ENLARGED CHAMBER THEREIN ADJACENT SAID BASE FLANGE, FORMING A SOFT PLASTIC VALVE HAVING A BASE FLANGE LARGER IN DIAMETER THAN SAID CHAMBER AND HAVING SEALING LIPS AT ITS TOP END. BONDING THE BASE FLANGE OF SAID VALVE RETAINER TO A HOLLOW PLASTIC ARTICLE WITH SAID BORE OF SAID VALVE RETAINER CONNECTING TO THE ATMOSPHERE, INFLATING THE HOLLOW ARTICLE AND STRETCHING SAID BASE FLANGE OF SAID VALVE RETAINER S AS TO ABOUT DOUBLE THE DIAMETER OF SAID CHAMBER, AND INSERTING SAID VALVE INTO SAID STRETCHED VALVE RETAINER BORE WITH SAID BASE FLANGE RECEIVED IN SAID CHAMBER AND WITH THE TOP END OF SAID VALVE EXTENDING RADIALLY INWARDLY FROM SAID VALVE RETAINER TO PROVIDE A REINFLATABLE ARTICLE.
