A nonsolvent, sealed septum connection for a water treatment cartridge

摘要

A button for providing a physical and sealing connection between a septum and an outlet stack of a water treatment cartridge having an opening. The button includes a first end, a second end opposite the first end, and a central portion which connects the first end to the second end. Located on the first end, there is a plurality of flexible locking members, configured for being inserted into the opening. To attach the button to the outlet stack, the locking members lockingly engage the outlet stack. The central portion has an annular groove provided with an O-ring. The O-ring facilitates a sealed connection between the button and the outlet stack. The button is connected to the septum by the use of either a washer and nonsolvent glue or heat staking. <IMAGE>
