A fluid mixing device includes inlet ports in fluid communication with respective source containers, an inlet check valve, a mixing container in fluid communication with the inlet check valve, a discharge port in fluid communication with a target container, and a discharge check valve in fluid communication with the mixing container and the discharge port. Responsive to a negative pressure at the mixing container, fluid is drawn from the respective source containers through the inlet ports and through the inlet check valve and into the mixing container, while the discharge check valve precludes drawing of fluid from the target container. Responsive to a positive pressure at the mixing container, fluid is expelled from the mixing container through the discharge check valve and into the target container, while the inlet check valve precludes discharge of fluid from the mixing container to the inlet ports and the source containers.

The sawtooth wave impeller tumbler may overcome the limitations of conventional mixers. An ideal solution would combine efficient mixing with ease of operation and cleaning, all while maintaining a high degree of precision and versatility in a wide range of applications. The device may comprise a pattern of internal sawtooth waves that provide for efficient and complete mixing of a solute and a solvent. In one embodiment the sawtooth wave impeller tumbler may comprise a tumbler for use by an individual user. The device may further comprise a plurality of components to improve the case of use and the functionality of the device such as, for example, a handle, a carabiner clip, a mouth cap, a removeable lid, or a support base.

A print material container comprising a body to hold print material, a housing, and a detecting member. The housing being coupled to the body and including a movable mass to move in the housing when a shaking force is applied to the print material container. The detecting member to detect the shaking force and to signal a feedback of the shaking force relative to a shaking force threshold.

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.

A beverage apparatus hand-holdable by a user to be portable, can include a beverage chamber housing that includes a chamber for storing a consumable liquid. The beverage apparatus can include a dispensing assembly that includes a receptacle. The receptacle can retain a vessel. The vessel can include an electronic tag and can contain an additive. The dispensing assembly can be operatively controllable by a controller to output the additive from the vessel into the consumable liquid. The beverage apparatus can include one or more sensors, devices, or assemblies that can be used to detect a volume of liquid in the chamber or a liquid level in the chamber. The beverage apparatus can include an apparatus computer processor portion (ACP) and an apparatus database portion.

An agitation apparatus according to an embodiment is used in a container which contains contents and an agitation tool magnetically attractable to agitate the contents. The agitation apparatus includes a first rotating member which rotates about a first axis. The first rotating member has a first locating surface on or above which the container is placed and a first magnet located away from the first axis. In a state where the container is placed on or above the first locating surface, the agitation tool is rotated about the first axis as the first rotating member rotates about the first axis.

A new mixing device for mixing solids and medium to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has an agitator with a center portion and distal portions of larger diameter than the center portion. The agitator is insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the agitator. The mixing device also has a weighted member attached adjacent to or within the center of the agitator that increases the momentum of the mixing device when in operation. The weighted member may have a metal core and polymer exterior.

A container for manually mixing contents therein includes a base and a lid, and when formed has a first horizontal axis, a second horizontal axis, and a vertical axis that is perpendicular to the horizontal axes. The base defines an elliptic-shaped base opening and a base chamber having two conjugate diameters D.sub.1 and D.sub.2 proximate the base opening. The lid defines an elliptic-shaped lid opening and a lid chamber having the two conjugate diameters D.sub.1 and D.sub.2 proximate the lid opening. The diameter D.sub.1 extends in a direction of the first horizontal axis and the diameter D.sub.2 extends in a direction of the second horizontal axis. A ratio of D.sub.1 to D.sub.2 is greater than 1. The container also includes grips for manually mixing the contents within the base and lid chambers by rotating the container about the second horizontal axis.

A shaker bottle is disclosed. The bottle includes a tumbler having a double walled structure, wherein the tumbler comprises a bottom wall internal surface, a side wall internal surface, a bottom wall external surface and a side wall external surface connected with the bottom wall internal surface and the side wall internal surface respectively through an air space arranged in between. The tumbler is configured to generate centrifugal force for shaking the predefined volume of liquid and the one or more consumable ingredients. The bottle includes a lid detachably coupled to the tumbler through one or more coupling mechanisms; an orifice to dispense a content from the internal chamber of the tumbler upon shaking; a closure to open or close the orifice through a sliding movement corresponding to the orifice. The bottle includes at least two rubber plugs removably inserted into respective holes to prevent liquid coolant from flowing out of corresponding air spaces between external and internal walls of the lid and the tumbler.

There is provided an infusion septum for a beverage container and more specifically, an infusion septum that is integrated within a beverage can end or a container cap and a method of infusion.
