The presently disclosed subject matter relates to a system for customizing a cosmetic product. The system includes: an interface device, in electronic communication with a single batch formulation device. The single batch formulation device is configured to formulate a customized cosmetic product, and a threaded container configured to be imported into the single batch formulation device containing a base and exported from the single batch formulation device containing the customized cosmetic.

A beverage stirring assembly for selectively stirring a liquid in a container includes a container that may contain a liquid. A stirring unit is removably coupled to the container and the stirring unit is selectively manipulated. The stirring unit stirs the liquid when the stirring unit is manipulated. Moreover, the stirring unit is selectively removed from the container thereby facilitating an interior of the container to be washed.

The present invention relates to a multistage stirred reactor, comprising a multiplicity of mutually adjacent reaction chambers and stirring elements for mixing the contents of at least one of the reaction chambers, wherein, between adjacent reaction chambers, there is in each case provided at least one opening that can be closed by means of closure means, such that in the open state there is a fluidic connection between the adjacent reaction chambers and in the closed state the adjacent reaction chambers are separated from one another. At least one of the closure means (300, 310, 320) is connected to an actuation rod (500, 510, 520) that is guided out of the stirred reactor. The actuation rod (500, 510, 520) can be moved back and forth between at least one first position and a second position, by rotation and/or displacement, wherein in the first position closure means (300, 310, 320) that are connected to the actuation rod (500, 510, 520) effect an open state of the opening assigned to them and in the second position closure means (300, 310, 320) that are connected to the actuation rod (500, 510, 520) effect a closed state of the opening assigned to them.

A drinking lid is disclosed herein. Exemplary implementations may include a stationary portion and a spinning portion. The stationary portion includes a drinking opening. The spinning portion is rotatably coupled to the stationary portion. The spinning portion is configured to be positioned in a position in which the drinking opening is covered such that the drinking lid is spill-resistant. The spinning portion is further configured to be positioned in a different position that leaves the drinking opening uncovered or open.

A blender assembly including a blender vessel and a blender hub. The blender hub having a plurality of first guide elements. The blender vessel having a rim, the blender vessel further having a plurality of second guide elements that each cooperate with a respective one of the first guide elements for forming a coupled and a sealed engagement to the blender hub. By releasing the coupling, the first and second guide elements cooperate to provide a two-stage release. A first stage of the release breaking the sealed engagement, and maintaining a loose coupled engagement, between the blender hub and the bender vessel. A second stage of the release, subsequent to the first stage of the release, releasing the coupled engagement between the blender hub and the blender vessel.
