An agitator may include one or more members adjustable between an expanded configuration and a compressed configuration. When the one or more members are in the expanded configuration, the agitator in a first set of two orthogonal dimensions is larger than an opening having a predetermined size. When the one or more members are in the compressed configuration, the agitator in a second set of two orthogonal dimensions is smaller than the opening having the predetermined size. The one or more members are biased to the expanded configuration in absence of external force applied to the one or more members. In use, the agitator may be inserted into a container through a neck of the container in the compressed configuration. The agitator may expand within the container so that the container does not fit through the neck of the container.

The invention relates to a mixing device for mixing one or more cosmetic preparations in a dispenser with a dispensing opening (8). The mixing device comprises at least two mixing plates (1) which comprise one or more passages (2), the diameter thereof tapering in direction of the dispensing opening.

Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

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.

The present disclosure relates to an aerosol delivery device filling system. The system includes multiple source containers each respectively including a differing aerosol precursor composition. The system further includes a mixing container configured to engage the source containers to receive and mix the aerosol precursor compositions to form a mixed aerosol precursor composition. An aerosol delivery device may engage the mixing container to receive at least a portion of the mixed aerosol precursor composition. A related method for customizing an aerosol precursor composition is also provided.

Provided are methods and devices for dissolving solid protein compositions, such as solid compositions comprising fibrinogen, in an aqueous solvent. The methods comprise use of a closed container containing a volume of solid fibrinogen composition and a head space wherein the pressure within the headspace is sub-atmospheric. Aqueous solvent is introduced into the container while maintain the sub-atmospheric pressure, and subsequent to addition of the solvent, the size of the headspace is decreased to bring the pressure to atmospheric pressure. The devices are suitable for use in the disclosed method.

The present invention relates to a dispenser for viscous materials that includes a static mixer, a first and second receptacle R.sub.1 and R.sub.2 for a first and second viscous material, connected in fluid communication with the static mixer, a first and second actuator configured for discharge of receptacle R.sub.1 and R.sub.2, an electrically or manually operable drive and a mechanical or hydraulic power transmission configured to translate drive motion into first and second actuator motion.

An agitator for disposition within a cavity of a vessel body containing a particulate includes a weighted portion and a stirring portion. The agitator is positioned and disposed relative to the vessel body to move the stirring portion through the particulate in response to movement of the weighted portion in response to gravitational and/or inertial forces acting on the weighted portion due to movement of the vessel body. Particulate storage vessel arrangements and methods of particulate mixing are also described.

The invention provides a bone cement mixing assembly including a mixer, a syringe barrel and a movable plug cover. The mixer includes a stirring rod and a stirring barrel. The stirring rod has holding end, a rod body and a stirring end. The stirring barrel has a barrel cover, a first barrel open, a first barrel body, a first barrel bottom, and a stirring space located in the first barrel body. The syringe barrel has a second barrel open, a second barrel body, a second barrel bottom, and an injection space located in the second barrel body. In this way, the complete-stirred bone cement in the stirring barrel can be directly collected and pushed into the syringe barrel through the movement of the movable plug cover to achieve the effect of completing the preparation of the bone cement quickly and efficiently.

A product preparation system and method wherein a single-use product container assembly and a multiple motion intelligent driving device are employed to process contents of the container assembly.
