Claim 7:
8. The container assembly according to claim 1, further comprising:
an inner sidewall having a collapsible accordion configuration, with an upper portion selectively removably couplable to a secondary inner sidewall of the second container in a male-female coupling configuration, with a lower portion coupled to the piston, and defining an inner sidewall cavity, the inner sidewall operably configured to have a collapsed configuration along an inner sidewall translation path and an expanded configuration along the inner sidewall translation path within the second container cavity, wherein the stem member is operably configured to apply the force on the piston to linearly translate the piston and inner sidewall along the inner sidewall translation path within the second container cavity to generate the negative pressure within the enclosed conduit for transportation of the liquid configured to be housed in the first container cavity to the inner sidewall cavity.
