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.

An additive delivery system may incorporate a cartridge system, including a container cap and a reservoir assembly that provides for storage of an additive. The container cap includes a mixing nozzle for mixing of the additive with a base fluid as the base fluid flows from the base fluid container through the cartridge. A one-way valve prevents backflow of base fluid and/or mixed base fluid/additive from an area downstream of the mixing nozzle such that the base fluid supply remains in a pure state.

A container lid for mixing different substances. The filter acts as both a mixing apparatus and a impediment to stop unmixed substances and solid items from passing through.

A lid may include first and second openings disposed within a spout. The first opening may provide a first fluid pathway to a fluid disposed in an attached container and the second opening may provide a second fluid pathway to a fluid disposed in the container. The lid may also include a spout at least partially defined by an outer wall. First and second openings may be disposed within the spout and the openings may be at least partially defined by the outer wall of the spout. A conduit, such as a straw, may be coupled to an opening. If desired, a closure may be connected to the lid and the closure may selectively close one or more of the openings.

A shaker for housing and dispensing food or drink items. The shaker has a top can sitting atop a bottom can. Each can contains a separate component. The top can is removed and its contents are added to the second can. This allows the user to control how much of the contents from the top can are added to the bottom can. A single multi-compartment vessel houses two separate ingredients and prevents their mixing.

A supplement shaker apparatus having a primary container for holding drinking fluid and a supplement container for holding a supplement wherein the supplement container is supported by the primary container with an opening therein. The apparatus also includes a lid assembly that is securable to the primary container and holds the supplement container in position in the supplement shaker apparatus. The apparatus further includes a spout connection element that extends from the opening in the supplement container to the lid to permit the drinking fluid to pass out of the primary container without contacting the supplement in the supplement container. A supplement shaker kit that includes a supplement container for holding a supplement wherein the supplement container is supported by a shaker bottle with an opening therein and a lid assembly that is securable to the shaker bottle and holds the supplement container in position relative to the shaker bottle. The kit also includes a spout connection element that extends from the opening in the supplement container to the lid to permit the drinking fluid to pass out of the shaker bottle without contacting the supplement in the supplement container.
