AN IMPROVED SEALING DEVICE.

Abstract

AN IMPROVED SEALING DEVICE IS DISCLOSED. THE SEALING DEVICE COMPRISES A HOLLOW FLAT RECTANGULAR RECEPTACLE, WHICH IS CLOSED AT ONE END AND OPEN ATG THE OTHER. THE INNER SURFACE OF THE WALLS OF THE RECEPTACLE DEFINE A PERIPHERAL SEAT SPACED APART FROM THE CLOSED END OF THE RECEPTACLE. THE SEALING DEVICE ALSO INCLUDES A FLAT PLUNGER TYPE ELEMENT WHICH DEFINES A LID FOR COVERING THE OPEN END OF THE RECEPTACLE BY A RESILLIENT MEMBER. TH SEALING DEVICE IS CHARACTERISED IN THAT THE PLUNGER BODY OF THE PLUNGER TYPE ELEMENT IS INSERTABLE INTO THE HOLLOW RECEPTACLE AND DEFINES DEFORMABLE DIVERGING BARBS ON ITS SIDES, WHICH CO-OPERATE WITH THE SAID SEAT DEFINED IN THE WALLS OF THE RECEPTACLE. THE PLUNGER TYPE ELEMENT IS EASILY INSERTABLE INTO THE RECEPTACLE BY COMPRESSING THE DIVERGENT BARBS WHICH EXPAND TO THEIR ORIGINAL FORM TO ENGAGE THE SAID SEAT WHEN THE PLUNGER BODY REACHES THE CLOSED END OF THE RECEPTACLE. THE SEALING DEVICE IS FURTHER CHARACTERISED IN THAT A GUIDE FORMATION IS PROVIDED ON THE PLUNGER ELEMENT TO PREVENT PLAY OF THE ELEMENT IN ITS OPERATIVE CONFIGURATION WHEN IT IS INSERTED IN THE RECEPTACLE.
