Abstract: 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.

Abstract: A modular flow monitoring package (MFMP) is provided for use in an additive delivery system. The MFMP may be manufactured as an add-on to be added to an existing additive delivery system, or may be incorporated into a cartridge or container structure. The MFMP includes a flow sensor for sensing flow of a base fluid and user actuator position sensors for sensing the position of one or more user actuated additive flow adjustment levers. A visual display, which may comprise an array of multi-color LED's may convey information to a user that is relevant to a user's use of the additive delivery system or the user's nutritional needs. Such information may include a current dosage of additive, being delivered, whether a recommended dosage of additive has been consumed, remaining life of a cartridge or supply of additive, and other data relative to health or performance monitoring.

Abstract: 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.

Abstract: A mixing cartridge delivery system, which mixes additive with base liquid flowing through it, utilizes a dispensing closure valve to achieve improved flow of mixed liquid from the cartridge. A closure base may include a tethered lid. A flexible valve, such as a slit valve, is supported on a valve supporting end of the closure base and retained thereon with a valve retainer that interlocks with the closure base. The system may include a one-way valve for base liquid and a mixing section defined in the cartridge. The dispensing closure valve achieves improved flow characteristics in combination with the base liquid valve. The dispensing closure valve also prevents leakage and inadvertent discharge from the cartridge system.

Abstract: A compact filtering and additive delivery system which is readily adaptable to a portable container, such as a sports bottle, and receives a modular additive container for the metered delivery of additive, such as flavor concentrate, to a stream of base liquid as the base liquid is drawn or dispensed from the container. The modular additive container configuration on the delivery system allows a consumer/user to experience different additives, such as different flavors or supplement compositions, for a given supply of base liquid, such as water, stored in the container. The system may be readily used with off-the-shelf containers, such as disposable water bottles. An additive container configuration provides modular additive delivery system as described herein.
