Beverage container and lid assembly

A method for forming a beverage, the method comprising:

• providing a first beverage concentrate to a first concentrate well of a beverage container lid assembly removably connected to a fluid container;
• causing flow of a reservoir liquid under vacuum from a reservoir of the fluid container to a central inlet of a venturi mixer of the beverage container lid assembly;
• causing flow of the first beverage concentrate under vacuum from the first concentrate well to a first inlet of the venturi mixer to permit flow of the beverage concentrate into the reservoir liquid via the venturi mixer to form the beverage;
• and
• dispensing the beverage from a central outlet of the venturi mixer,
• wherein the beverage container comprises a bottom surface and a neck and a wall structure extending therebetween to form a reservoir to hold a reservoir liquid, a beverage container lid assembly removably connected to the neck, a seal plate including a back-flow valve removably connected to the beverage container lid assembly, and a straw extending through the lid assembly and in fluid communication with the reservoir and feed line, and
• wherein the beverage container lid assembly comprises at least one concentrate well to hold a concentrate vessel, a concentrate vessel retainer for each concentrate well to secure the concentrate vessel in the concentrate well, a feed line for each concentrate well comprising a feed line needle to puncture the concentrate vessel in the at least one concentrate well, a venturi mixer in fluid combination with each feed line, and a mixing valve for each feed line, wherein fluid flows from the concentrate well through the feed line to the venturi mixer when the mixing valve is open, and wherein fluid flows from the concentrate vessel through the feed line to the venturi mixer when the mixing valve is open and the concentrate vessel is punctured by the feed line needle.

A beverage container lid assembly comprising:

• at least four concentrate wells circumferentially positioned equidistant from a longitudinal axis of the beverage container lid assembly to each hold a concentrate vessel having a fluid contained therein, and;
• a concentrate vessel retainer for each concentrate well to secure the concentrate vessel in the concentrate well;
• a feed line for each concentrate well comprising a feed line needle to puncture the concentrate vessel in the concentrate well;
• a venturi mixer in fluid communication with each feed line and aligned with the longitudinal axis of the beverage container lid assembly, wherein the venturi mixer comprises a central inlet along a longitudinal axis of the venturi mixer and an inlet for each feed line below the horizontal and at a 90 degree angle relative to the longitudinal axis of the venturi mixer;
• a back-flow valve in fluid communication with and upstream from the venturi mixer;
• a filter in fluid communication with and upstream from the venturi mixer;
• wherein fluid flows from the concentrate vessel through the feed line to the venturi mixer when the mixing valve is open and the concentrate vessel is punctured by the feed line needle,
• wherein no fluid flows from the concentrate vessel through the feed line to the venturi mixer when the mixing valve is closed and the concentrate vessel is punctured by the feed line needle.
