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 food-processing device for blending and mixing food comprises a mixing vessel, a blade holder, and a motor base. The motor is a high power motor. The device has various safety features designed for the high power motor. The blade holder comprises a safety mechanism that prevents the motor base from operating without the mixing vessel covering the blade. On the surface of the motor base, it has raised area that is complementarily shaped with some recesses on the bottom of the blade holder to align the blade holder and the motor base. It also has a drainage hole that prevents the accumulation of liquid in the well of the motor base. The motor is mounted on the ceiling of the motor housing through a bracket with multiple dampers. The circuit of the motor has soft start and automatic turn off features.

The invention provides a multi-compartment container for storing and dispensing separately a plurality of consumable liquids that can be mixed in an accurate and repeatable manner. Each storage compartment within the container encloses a predetermined quantity of a consumable liquid, wherein the first compartment is filled with a first liquid and the other compartments are filled with second and third liquids. The individual storage compartments are structurally merged to form elongated dispensing compartments each with a first end and a second end, wherein a one-way outlet positioned at the first end and a one-way outlet located at the second end permits passage of liquid from the storage compartments into the corresponding dispensing compartments. Upon fully inverting the container, the designated outlet of each dispensing compartment is opened, wherein precise amounts of liquids in the first, second, and third compartments are dispensed at constant volume ratio using gravity.

A container (10) is described. The container (10) comprises: a first receptacle (12) defining a first chamber (16) and having a first aperture (32); and a second receptacle (14) defining a second chamber (18) and having a second aperture (42). The container (10) also includes a reclosable opening which allows access to the first and second receptacles (12, 14). The second receptacle (14) is movably mounted upon the first receptacle (12) such that the first and second apertures (32, 42) may be aligned to allow the contents of the second chamber (18) to be introduced into the first chamber (16).

An adjustable additive cartridge that provides adjustable metering of additive to a base fluid as the base fluid is flowing through the cartridge. A spout is mounted for limited rotation within a base element of the cartridge. Rotation of the spout results in varying degrees of flow of additive into a base fluid flow path through the cartridge. The cartridge may be used with a portable beverage container, such as a sports bottle or off-the-shelf water bottle. The supply of base fluid in a container used with the cartridge may be kept in an unmixed, pure state, and other cartridges, each having different additives (i.e., flavors) may be used interchangeably with the same base fluid supply. The cartridge allows a consumer/user to experience different additives, such as different flavors or supplement compositions, for a given supply of base liquid in a single container. A check valve on the cartridge prevents backflow of the base fluid. An integrated filter for filtering base fluid flowing into the cartridge may be provided. The additive cartridge may be sealed to provide for extended storage and to provide a user/consumer with evidence of integrity, quality and/or tampering prior to purchase and/or use. Visual and tactile indicators of the amount of additive being added to a base fluid may be provided. A container may retain a spare additive adjustable cartridge on the container.
