Apparatus for transfer of high viscosity fluids

A fluid apparatus for transferring highly viscous material comprising:

• a pressure chamber defining an interior space, the pressure chamber having a door providing selective access to the interior space;
• a dispensing piston extending into the interior space, the dispensing piston having an inner end configured to seat the mouth of a secondary container, the dispensing piston includes a primary seal configured to engage with an inner surface of a secondary container;
• and
• a dispensing container adapter joined to the dispensing piston, the dispensing container adapter configured to receive a dispensing container, the dispensing container defining a material outlet;
• and
• wherein pressurization of the pressure chamber forces a secondary container seated on the dispensing piston to move increasingly farther onto the dispensing piston thereby moving material inside a secondary container through the material outlet and into a dispensing container seated on the dispensing container adapter.

A method of moving highly viscous material from a secondary container to a dispensing container, comprising the steps of:

• providing a pressure chamber with an internal dispensing piston and a dispensing container seat, the dispensing piston defining a material outlet in fluid communication with the dispensing container seat;
• fitting a dispensing container onto the dispensing container seat;
• seating a secondary container containing a material onto the dispensing piston within the pressure chamber;
• introducing pressurized air into the pressure chamber such that force exerted by the pressurized air causes the secondary container to move increasingly farther onto the dispensing piston, whereby material within the secondary container is moved through the material outlet to the dispensing container.

An apparatus for moving high viscosity fluid from a secondary container with an internal piston to a dispensing container comprising:

• a pressure chamber defining an interior space, the interior space being configured to receive and fully enclose a secondary container, the pressure chamber configured to be selectively pressurized;
• a secondary container seat disposed inside the pressure chamber and configured to receive a secondary container having an internal piston, the secondary container seat configured to receive a secondary container in a position in which an internal piston is subject to pressure within the interior space;
• a dispensing container seat disposed outside the pressure chamber and configured to receive a dispensing container;
• and
• a container adapter penetrating a wall of the pressure chamber and forming at least a portion of the secondary container seat and at least a portion of dispensing container seat, the container adapter having an inner end configured to adjoin with an outlet of a secondary container and an outer end configured to adjoin with an inlet of a dispensing container, the container adapter defining a material outlet extending entirely therethrough to define a material flow path from the inner end to the outer end;
• and
• wherein adequate pressurization of the pressure chamber applies a force to a piston in a secondary container seated on the secondary container seat to move material inside a secondary container through the material outlet and into a dispensing container seated on the dispensing container seat.
