Apparatus and method for mixing and dispensing fluids

An apparatus for mixing a concentrated product and a liquid, comprising:

• a body defining an internal volume;
• and
• a mixing device positioned at least partially within the internal volume,
• wherein the mixing device comprises one or more vanes that separate the internal volume into a first portion and a second portion when the mixing device is in a first position, the mixing device further comprising a guide that at least partially surrounds the one or more vanes,
• wherein the first portion and the second portion are in fluid communication with one another when the mixing device is in a second position,
• wherein the one or more vanes define a notch or slot, and wherein the guide is positioned within the notch or slot such that an outer radial surface of the guide is substantially flush with outer radial surfaces of the one or more vanes, and
• wherein outer radial surfaces of the one or more vanes are in contact with an inner surface of the body to sealingly separate the first and second portions when the mixing device is in the first position.
