A dispensing assembly and method for dispensing a mixture of a first fluid component and a second fluid component. The dispensing assembly generally comprises a container coupled with a nozzle in a unique manner to achieve a mechanical and fluid connection. More specifically, the container includes a first chamber and a second chamber. The first and second chambers are adapted to respectively hold the first and second fluid components. The nozzle has an inlet end and an outlet end. First and second connecting elements are located at the inlet end of the nozzle. Another mating pair of connecting elements, i.e., third and fourth connecting elements, of the container respectively communicate with the first and second chambers. The first and second connecting elements are respectively capable of being removable coupled to the third and fourth connecting elements to establish fluid paths from the first and second chambers into the inlet end of the nozzle. A coupling element selectively couples the inlet end of the nozzle to the container.
