Abstract
A static mixer suitable for mixing liquids, pastes, creams, gels or other fluids. Fluids introduced into a static mixing cavity of the static mixer are mechanically mixed by the static mixing cavity, and then dispensed from an outlet as a mixed fluid. The static mixer may be formed by two housing halves that are hingedly connected so that the static mixer can be easily opened for cleaning the static mixing cavity.
Claims11
A fluid mixing system, comprising:
- first and second fluid cartridges having first and second fluid connector fittings, respectively, the first and second cartridges having a flexible housing configured so that when pressed, forces are applied to a fluid contained therein;
- a static mixer including:
- a housing that includes a first housing half and a second housing half hingedly connected at one end, the first housing half and the second housing half configured to pivot with respect to the other about a hinge from a closed position to an open position;
- first and second connector ports configured to be removably coupled to the first and second fluid connector fittings;
- a static mixing cavity disposed in the housing and connected in fluid communication with the first and second connector ports, the static mixing cavity configured to promote mixing of one or more fluids supplied thereto from the first and second fluid cartridges as the one or more fluids pass through the static mixing cavity;
- and
- a fluid outlet disposed in fluid communication with the static mixing cavity for dispensing a mixing fluid.
