ABSTRACT:
A container for storage, transport, and dispensing of liquid chemicals includes a fluid container having a port, a dip tube having a fluid passage from an upper end to a lower end of the dip tube, a dip tube coupling at the upper end of the dip tube for insertion into the port, and a rupturable membrane sealed over a top end of the port. The dip tube coupling has a cavity in its upper end and a fluid passage connecting the cavity with the fluid passage of the dip tube. The dip tube coupling defines a gas passage extending from an interior of the fluid container to the cavity. A rupturable membrane is positioned over a top end of the port to seal the cavity, so that when the rupturable membrane is punctured or removed, gas from the fluid container, which has accumulated in the cavity, is permitted to escape. To remove the liquid chemical, the cap is removed to expose the rupturable membrane. A probe is next inserted through the membrane to allow gas to escape, and into the cavity, whereby the probe, upon insertion into the cavity, causes the gas passage to be blocked. Liquid is dispensed from the fluid container through a fluid passage within the dip tube and through a flow passage within the probe.
