## Abstract

A disposable mixing system includes a lid having an opening and configured to hold contents within a container, a strainer configured to couple with the container and the lid in a position between the container and the lid, where the strainer mixes the contents responsive to shaking the container, and a cap configured to cover the opening of the lid, where at least the lid and the strainer are formed in a unified piece. The system may be manufactured from a single sheet of plastic using thermoforming. The strainer may use flat surfaces and large triangular orifices for efficient mixing and manufacture, while the lid may have a spout sized to prevent clogging and pressure build-up.

## Claims

### Claim 1

A mixing device comprising:
a lid for a container, the lid comprising an opening; and
a strainer configured to couple with the container and the lid in a position between the container and the lid,
wherein the lid and the strainer are formed in a unified piece such that the strainer is configured to snap on to a perimeter of the container, and
wherein the strainer is coupled to the lid via a projection comprising one or more notches.

### Claim 2 (depends on 1)

The mixing device of claim 1, wherein, when the container is shaken, the strainer mixes contents in the container.

### Claim 3 (depends on 1)

The mixing device of claim 1, wherein the projection is a hinge configured to be bent in order to position the strainer against an underside of the lid.

### Claim 4 (depends on 1)

The mixing device of claim 1, wherein both the lid and the strainer are composed of a plastic material and are manufactured via thermoforming.

### Claim 5 (depends on 1)

The mixing device of claim 1, wherein the opening is in a form of a spout.

### Claim 6 (depends on 1)

The mixing device of claim 1, wherein the strainer comprises a groove configured to snap on to a projecting rim of the container.

### Claim 7 (depends on 1)

The mixing device of claim 1, wherein the lid and the strainer each comprise aligned mating structures that are configured to secure the lid and the strainer together.

### Claim 8 (depends on 7)

The mixing device of claim 7, wherein the mating structures are composed of a flexible material.

### Claim 9 (depends on 7)

The mixing device of claim 7, wherein the mating structures comprise one or more projections.

### Claim 10 (depends on 9)

The mixing device of claim 9, wherein the mating structures comprise one or more recesses that correspond to the one or more projections.

### Claim 11 (depends on 1)

The mixing device of claim 1, wherein the strainer comprises a plurality of flat surfaces and a plurality of orifices between the plurality of surfaces.

### Claim 12 (depends on 11)

The mixing device of claim 11, wherein each of the plurality of orifices is triangular in shape.

### Claim 13 (depends on 11)

The mixing device of claim 11, wherein the plurality of orifices is oriented symmetrically around a center of the strainer.

### Claim 14

A method for mixing contents in a container, the method comprising:
obtaining a lid for a container and a strainer configured to couple with the container and the lid in a position between the container and the lid, wherein the lid comprises an opening, wherein the lid and the strainer are formed in a unified piece such that the strainer is configured to snap on to a perimeter of the container, and wherein the strainer is coupled to the lid via a projection;
separating the strainer from the lid;
placing contents to be mixed inside the container;
placing the strainer over a container opening and pressing the strainer down on to the container opening;
placing the lid over the strainer and pressing the lid down on to the strainer; and
shaking the container, thereby mixing the contents.

### Claim 15 (depends on 14)

The method of claim 14, wherein the placing the strainer further comprises wrapping a groove of the strainer over a lip of the container, thereby securing the strainer over the container opening.

### Claim 16 (depends on 14)

The method of claim 14, wherein the placing the lid over the strainer further comprises mating one or more structures on the lid to one or more corresponding structures on the strainer, thereby securing the lid over the strainer.

### Claim 17 (depends on 16)

The method of claim 16, wherein the one or more corresponding structures on the strainer comprises an outer projection, and wherein the one or more structures on the lid comprises an inner recess configured to snap over the outer projection.

### Claim 18

A mixing device comprising:
a lid for a container, the lid comprising an opening; and
a strainer configured to couple with the container and the lid in a position between the container and the lid, wherein the strainer mixes contents in the container when the container is shaken;
wherein the lid and the strainer are formed in a unified piece wherein the strainer is configured to snap on to a perimeter of the container, and
wherein the strainer is coupled to the lid via a projection comprising one or more notches.

### Claim 19 (depends on 18)

The mixing device of claim 18, wherein the strainer comprises a groove that is configured to fit over a lip of the container.
