A jar or other storage container with an integrated stirring device, where the contents of the jar or storage container can be stirred and mixed together without having to completely open the jar or storage container. The core components in one embodiment are a top portion that contains external threads, a lid portion which contains internal threads, a spindle with an etched self-reversing screw pattern, a hub, one or more stirring blades, and a nut. The stirring blades have one end attached at a hub that is free to rotate on the spindle, the other end is attached to a nut that can travel up and down the self-reversing screw pattern, and the spindle is fixed to the lid portion. The surface area of the stirring blade(s) can be changed to accommodate different thicknesses and viscosities of different fluids and semi-fluids placed in the storage container.

A fluid mixing system includes a container, such as a flexible bag, bounding a compartment. A flexible drive line is disposed within the compartment, the drive line having a first end rotatably connected to a first end of the container and an opposing second end rotatably connected to a second end of the container. At least one mixing element, such as an impeller, can be coupled with the flexible drive line. Rotation of the drive line facilitates rotation of the impeller within the container.

A device and system for temporarily sealing an orifice in a beverage container lid comprising a plug (10, 110, 210, 310) having an upper surface (14, 114, 214), a body portion (12, 112), and a lower surface (16, 116, 216), said body portion adapted to be inserted and releasably retained in the orifice to provide a temporary seal thereof, and an external member (20, 120, 220) located on the upper surface of the plug configured to allow a user to grip the plug for ease of removal from the orifice.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

A stirring member (90) for an industrial stirrer, in particular for a stirring rod arrangement, for connecting to a stirring mechanism combinable with a container for receiving liquids, wherein the container comprises a filling opening closable with a lid for filling the container in an upper bottom wall, wherein the stirring member is connectable to a rod-shaped stirring member carrier of the stirring rod arrangement, wherein the stirring member comprises a bearing end (91) and a stirring member end (94) connected to the bearing end (91) via a link (92) and having a flow tube (93), wherein the flow tube comprises a tube wall, wherein the flow tube comprises an annularly formed accumulating surface (95) at its flow inlet cross section, wherein the accumulating surface comprises at least one circular ring sector (96) which is inclined with respect to an inflow plane of the flow inlet cross section.

A fluid mixing system includes a container, such as a flexible bag, bounding a compartment. A flexible drive line is disposed within the compartment, the drive line having a first end rotatably connected to a first end of the container and an opposing second end rotatably connected to a second end of the container. At least one mixing element, such as an impeller, can be coupled with the flexible drive line. Rotation of the drive line facilitates rotation of the impeller within the container.

A mounting assembly is provided, including: a drive coupler shaped to engage a coupling member on a shaft positionable within a container defining an aperture to allow passage of the shaft; and a funnel positioned within the aperture to receive the drive coupler and guide the drive coupler to the coupling member. The assembly provides ergonomic advantages as the user is not required to lift the drive to reach the aperture.

A bioreactor includes a flexible container and an impeller assembly having a hollow tube. The impeller assembly is coupled to the flexible container. At least one mixing element is removably disposed on the hollow tube. A drive shaft is adapted to engage the hollow tube of the impeller assembly and facilitate rotational movement of the hollow tube.
