Disposi-Shake

We are looking to create a prototype of a disposable shaker cup. This cup will hold 20oz of liquid. The cup will need to be designed to be shaken vigorously with a detachable lid (to be designed as well). The lid will have have two components. 1.) A perforated 'lip' that can be flipped up after the shaking in order to drink from or pour out. 2.) The bottom of the lid needs to be designed in a way that will help break up chunks of powder when mixed with water and shaken. We envision the bottom of the lid having protruding 'blades' resembling a sliced pizza with a circle in the middle. (see attached file). This should be flat topped (see example attachment). Overall this product is meant to be used once and disposed of.
