Patent ID: 7891522

Claim:
A method, comprising: providing an airless dispensing pump with an inlet valve member sealing an inlet port of the pump to define a pump cavity in the pump, wherein the inlet valve member includes an outer support member, an inner seal member that seals the inlet port and at least two connection legs that connect the outer support member to the inner seal member; wherein a container has a bottom with a support member; filling the container with fluid through a top opening of the container; pushing a follower piston to the bottom of the container against the support member prior to said filling; wherein said filling includes retracting a diving nozzle that dispenses the fluid in a progressive manner from the bottom of the container to the top opening of the container; diving the diving nozzle to the bottom of the container immediately above the follower piston before said retracting the diving nozzle; and priming the airless dispensing pump by securing the airless dispensing pump to the top opening of the container so that pressure of the fluid inside the container opens the inlet valve member to at least partially fill the pump cavity with the fluid, wherein during said priming the airless dispensing pump seals with the container to pressurize the container.
