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.

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.

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 urea solution injection device includes an exhaust pipe for discharging exhaust gas generated in a combustion chamber to the exterior; an injector is installed and pierces into the exhaust pipe to inject urea solution into the exhaust gas flowing in the exhaust pipe. A catalyst is disposed at a position after the injector when viewed in a flow direction of the exhaust gas and the exhaust gas is discharged to the exterior to decompose the exhaust gas mixed with the urea solution. A urea solution mixer is provided at an end of the injector and installed and pierces into the exhaust pipe. Accordingly the urea solution injected from the injector is dispersed therein. An installation unit provides for the urea solution mixer to be installed in the exhaust pipe and pierces into the exhaust pipe.

The invention relates to a method of making a personal care composition, the method comprising steps of: providing a mixer comprising a housing comprising a first fluid inlet, a second inlet, and a fluid outlet, the mixer further rotor rotatably connected with the housing, the rotor comprising blades positioned within the housing to define cells between neighboring blades and the housing; preparing a personal care chassis base comprising surfactants and water; preparing a microcapsule composition comprising microcapsules, and air; advancing personal care chassis base along a flow path from the first fluid inlet toward the fluid outlet; transferring the microcapsule composition from the second inlet to the flow path by rotating the rotor; directing air in the microcapsule composition from inside the cells toward the second inlet; combining the microcapsule composition with the personal care chassis base to form the personal care composition; and advancing the personal care composition from the outlet. The microcapsule composition may further comprise an aqueous carrier including, but not limited to, water. The personal care composition can be transported to a filling line and filled through a filling nozzle into a bottle.
