Aerosol valve and method of manufacture of same

Claim 1

AN AEROSOL VALVE FOR AN OPEN MOUTHED CONTAINER COMPRISING A LID ADAPTED TO SEALINGLY ENGAGE THE CONTAINER AT THE OPEN MOUTH THEREOF, SAID LID HAVING AN OPENING EXTENDING THERETHROUGH, A HOLLOW VALVE TUBE EXTENDING THROUGH SAID OPENING, SAID TUBE BEING TILTABLE WITH RESPECT TO SAID LID, ABUTMENTS ON SAID TUBE IN BOTH SIDES OF SAID LID FOR LIMITING MOVEMENT OF SAID TUBE ON BOTH SIDES OF SAID WITH RESPECT TO SAID LID, AN APERTURE IN SAID VALVE TUBE BENEATH SAID LID, AND A RESILIENT BODY FIXED TO SAID LID AND SURROUNDING SAID VALVE TUBE, SAID RESILIENT BODY SEALING SAID LID OPENING TO PREVENT PASSAGE THERETHROUGH OUTSIDE OF SAID TUBE AND AT THE SAME TIME NORMALLY SEALING SAID APERTURE IN SAID VALVE TUBE, SAID RESILIENT BODY BEING COMPRESSIBLE UPON TILTING OF SAID TUBE TO UNBLOCK SAID APERTURE, WHEREUPON PRESSURIZED CONTENTS OF THE CONTAINER AUTOMATICALLY PASS OUT THROUGH SAID TUBE.

Claim 3

THE METHOD OF MAKING AN AEROSOL VALVE COMPRISING THE FOLLOWING STEPS: (1) FORMING A CIRCULAR LID WITH AN INTERMEDIATE CYLINDRICAL CUP PORTION; (2) FORMING AN OPENING IN THE TOP WALL OF SAID CUP PORTION; 3) DISHING THE EDGE OF SAID OPENING SO AS TO ENLARGE SAME; (4) FORMING A RIGID VALVE TUBE WITH A CLOSED BOTTOM EXCEPT FOR A SMALL APERTURE ADJACENT SAID BOTTOM AND WITH AN OPEN TOP; (5) PROVIDING A PAIR OF SPACED CIRCULAR FLANGES ON THE OUTSIDE OF SAID TUBE, THE UPPER OF WHICH IS JUST SLIGHTLY SMALLER THAN THE ENLARGED OPENING IN THE LID AND THE LOWER OF WHICH IS LARGER THAN THE SAID ENLARGED OPENING; (6) PASSING THE AFORESAID TUBE UPWARDLY THROUGH SAID ENLARGED LID OPENING UNTIL THE LOWER FLANGE ENGAGES THE DISHED EDGE OF THE ENLARGED OPENING; (7) STRAIGHTENING THE DISHED EDGE OF THE OPENING IN ORDER TO DECREASE THE SIZE OF SAME AND TO CAPTURE THE LID BETWEEN THE FLANGES OF THE VALVE TUBE; AND (8) FORCING A CORED RUBBER PLUG UP INTO SAID CUP PORTION SO THAT THE LOWER END OF THE VALVE TUBE IS RECEIVED IN THE CORE OF THE PLUG WITH SAID APERTURE NORMALLY SEALED BY SAID PLUG.

Claim 4

THE METHOD OF MAKING AN AEROSOL VALVE COMPRISING THE FOLLOWING STEPS: (1) FORMING A CIRCULAR LID WITH AN INTERMEDIATE CYLINDRICAL CUP PORTION; (2) FORMING AN OPENING IN THE TOP WALL OF SAID CUP PORTION; 3) DISHING THE EDGE OF SAID OPENING SO AS TO ENLARGE SAME; (4) FORMING A RIGID VALVE TUBE WITH A CLOSED BOTTOM EXCEPT FOR A SMALL APERTURE ADJACENT SAID BOTTOM AND WITH AN OPEN TOP; (5) PROVIDING A PAIR OF SPACED CIRCULAR FLANGES ON THE OUTSIDE OF SAID TUBE, THE UPPER OF WHICH IS JUST SLIGHTLY SMALLER THAN THE ENLARGED OPENING IN THE LID AND THE LOWER OF WHICH IS LARGER THAN THE SAID ENLARGED OPENING; (6) PASSING THE AFORESAID TUBE UPWARDLY THROUGH SAID ENLARGED LID OPENING UNTIL THE LOWER FLANGE ENGAGES THE DISHED EDGE OF THE ENLARGED OPENING; (7) STRAIGHTENING THE DISHED EDGE OF THE OPENING IN ORDER TO DECREASE THE SIZE OF SAME AND TO CAPTURE THE LID BETWEEN THE FLANGES OF THE VALVE TUBE; AND (8) FORCING A CORED RUBBER PLUG UP INTO SAID CUP PORTION SO THAT THE LOWER END OF THE VALVE TUBE IS RECEIVED IN THE CORE OF THE PLUG WITH SAID APERTURE NORMALLY SEALED BY SAID PLUG.
