Abstract

The sawtooth wave impeller tumbler may overcome the limitations of conventional mixers. An ideal solution would combine efficient mixing with ease of operation and cleaning, all while maintaining a high degree of precision and versatility in a wide range of applications. The device may comprise a pattern of internal sawtooth waves that provide for efficient and complete mixing of a solute and a solvent. In one embodiment the sawtooth wave impeller tumbler may comprise a tumbler for use by an individual user. The device may further comprise a plurality of components to improve the case of use and the functionality of the device such as, for example, a handle, a carabiner clip, a mouth cap, a removeable lid, or a support base.

Claims (43)

1. A sawtooth wave impeller tumbler, comprising:

a main body; and

a sawtooth wave;

wherein said main body comprises a fluid container;

wherein said sawtooth wave comprises a shape, an angle, a spacing, a height, and a sense;

wherein said sawtooth wave defines an interior wall of said main body;

wherein said shape of said sawtooth wave comprises a ridge having a first side, a sharp edge, a second side, and a length;

wherein said first side of said shape and said second side of said shape are asymmetrical;

wherein said angle of said sawtooth wave is a non-zero angle relative to said main body;

wherein said spacing of said sawtooth wave is proportional to a diameter of said main body; and

wherein said height of said sawtooth wave is proportional to said length of said ridge.

2. The sawtooth wave impeller tumbler of claim 1 ,

wherein said first side of said shape comprises a half sinusoid; and

wherein said second side of said shape comprises a quarter circle.

3. The sawtooth wave impeller tumbler of claim 2 , further comprising:

a tumbler lid assembly;

wherein said tumbler lid assembly is removably attached to an upper end of said main body.

4. The sawtooth wave impeller tumbler of claim 3 ,

wherein said tumbler lid assembly further comprises a mouthpiece, a mouthpiece cover, an air vent, and a handle.

5. The sawtooth wave impeller tumbler of claim 4 , further comprising:

a tumbler base;

wherein said tumbler base is removably attached to a lower end of said main body.

6. A sawtooth wave impeller tumbler, comprising:

a main body; and

a sawtooth wave;

wherein said main body comprises an insert;

wherein said sawtooth wave comprises a shape, an angle, a spacing, a height, and a sense;

wherein said sawtooth wave defines an interior wall of said main body;

wherein said shape of said sawtooth wave comprises a ridge having a first side, a sharp edge, a second side, and a length;

wherein said first side of said shape and said second side of said shape are asymmetrical;

wherein said angle of said sawtooth wave is a non-zero angle relative to said main body;

wherein said spacing of said sawtooth wave is proportional to a diameter of said main body; and

wherein said height of said sawtooth wave is proportional to said length of said ridge.

7. The sawtooth wave impeller tumbler of claim 6 ,

wherein said first side of said shape comprises a half sinusoid; and

wherein said second side of said shape comprises a quarter circle.

8. The sawtooth wave impeller tumbler of claim 7 , further comprising:

a tumbler lid assembly; and

a tumbler base;

wherein said main body is removably inserted into said tumbler base; and

wherein said tumbler lid assembly is removably attached to an upper end of said tumbler base.

9. The sawtooth wave impeller tumbler of claim 8 ,

wherein said tumbler lid assembly further comprises a mouthpiece, a mouthpiece cover, an air vent, and a handle.
