Liquid chemical container and dispensing system

A liquid chemical handling system comprising:

• a container which comprises:
• an outer container having a mouth;
• a fluid container having a port and an interior;
• means for supporting the fluid container within the outer container;
• 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, the dip tube coupling having a cavity in its upper end, and a fluid passage connecting the cavity with the fluid passage of the dip tube;
• vent means intermediate the interior of the fluid container and the cavity for permitting gas flow between the interior of the fluid container and the cavity;
• and
• a seal over the top end of the port so that when the seal is opened, gas is permitted to escape from the fluid container;
• and
• a dispenser which comprises:
• a probe insertable through the rupturable seal and into the cavity, the probe having a flow passage therein;
• and
• means connected to the probe for receiving liquid chemical dispsened from the fluid container through the fluid passage of the dip tube, through the fluid passage of the dip tube coupling, and through the flow passage of the probe.

A container for liquid chemicals, the container comprising:

• an outer container having a mouth;
• a fitment for mounting in the mouth, whereby the fitment defines a port;
• a flexible bag mounted to a lower end of the fitment and positioned within the outer container;
• 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, the dip tube coupling having a cavity in its upper end which is connected to the fluid passage of the dip tube;
• vent means intermediate an interior of the flexible bag and the cavity for permitting gas flow between the interior of the fluid container and the cavity;
• sealing means for sealing the cavity so that when the sealing means is removed, gas is permitted to escape from the cavity;
• and
• means in fluid communication with a space between inner walls of the outer container and the flexible bag for permitting fluid under pressure to flow into the space between the outer container and the flexible bag to force liquid out of the flexible bag through the fluid passage of the dip tube.
