One embodiment relates to a device for the production of a bone cement dough from a monomer liquid and a cement powder comprising a cartridge with an internal space; a cartridge head with a dispensing opening; a conveying plunger that is arranged in the internal space of the cartridge and is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a dispensing plunger between the dispensing opening and the conveying plunger that is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a first hollow space, in which the cement powder is arranged; a second hollow space that is bordered by the dispensing plunger and the conveying plunger; a fluid opening that is arranged in the conveying plunger; a feedthrough that connects the first hollow space and the second hollow space to each other, and a closure means that is arranged on a rear side of the dispensing plunger. The closure means projects away from the dispensing plunger and is situated at a distance from the fluid opening. The fluid opening is closable with the closure means. The closure means is mobile in the closed fluid opening such that the fluid opening stays closed, while the conveying plunger is pushable further in the direction of the dispensing plunger.

A system for providing a single serving of a frozen confection, wherein the system comprises a pod comprising at least one ingredient for providing a single serving of a frozen confection; the system cools the pod; the system introduces water into the pod; the system simultaneously stirs the contents of the pod while scraping at least one wall of the pod to prevent a build-up of the frozen confection on the at least one wall of the pod; and the system ejects the frozen confection out of the pod.

A device for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material. The device comprises: a nozzle for dispensing the third material; a first container adapted to store a first ingredient material and mix the first ingredient material with a second ingredient material; a second container disposed within the first container, and moveable between a storage position in which a second ingredient material is stored in the second container and a mixing position in which the second ingredient material is moved to the first container; a mixer that longitudinally extends into the first and second containers; a handle alternatively coupled to the mixer to mix the first and second ingredient materials or to the second container to move the second container to a dispensing position to dispense the third material. During use, the first container is rotated causing the second container to move relative to the first container and the second material to flow into the first container for mixing. After mixing, the handle is uncoupled from the mixer and coupled to the second container to dispense the third material from the nozzle. Embodiments are also described herein for a method of making the device and a method of using the device.

A container for bone cement includes a first member defining a chamber, which contains a first ingredient. The chamber also includes a second member movably coupled to the first member. The second member includes a mixing device that is movably disposed within the first chamber, and the second member defines a second chamber containing a second ingredient. The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.

One aspect relates to a method of producing a bone cement from at least two starting components in a device comprising a first hollow cylinder-shaped container and a second hollow cylinder-shaped container, a vessel arranged in the first container, whereby a monomer liquid is stored in the vessel. The aspect also relates to a device for providing a bone cement from two starting components, comprising a hollow cylinder-shaped first container, in which a vessel for a monomer liquid as first starting component can be stored, a hollow cylinder-shaped second container comprising a first internal space, in which a bone cement powder as second starting component can be stored, and a second internal space into which the monomer liquid can be conveyed, a fluid-conducting conveying means arranged between the first internal space and the second internal space, whereby the first container and the second container are axially connected to each other.

One aspect relates to a device for providing a bone cement from two starting components, having a hollow cylinder-shaped first container, in which a monomer liquid as first starting component can be stored, a hollow cylinder-shaped second container comprising a container wall, a first internal space, and a second internal space, whereby a bone cement powder as second starting component can be stored in the first internal space, and whereby the monomer liquid can be conveyed into the second internal space, a fluid-conducting conveying means arranged between the first internal space and the second internal space, whereby the first container and the second container are axially connected to each other.

An apparatus for transferring a viscous material comprising: a) a first container capable of containing a viscous material; b) a transfer piston insertable in the first container so that the piston forms a circumferential seal with respect to the container, the transfer piston including a hole; and c) a mechanism for attaching an aperture of a second container to the hole in the transfer piston wherein insertion of the transfer piston into the first container causes the viscous material to pass through the aperture into the second container.

A liquid-liquid mixing device (10, 210) includes a barrel (20, 220) with a liquid port (23) at or adjacent one end. A plunger assembly (30) is reciprocably moveable along an axis in the barrel (20, 220) and includes a seal member (31, 231) and an agitator (50, 250). The seal member (31, 231) is in sealingly slidable engagement with the internal wall of the barrel (20, 220) to define a variable volume chamber (24, 224) therein in communication with the liquid port. The agitator (50, 250) is reciprocably moveable in the variable volume chamber (24, 224), which agitator (50, 250) includes one or more end to end passages (54) through which liquid in the chamber (24, 224) is forced as the agitator (250) reciprocates in the chamber (24, 224). The device (10) also includes a mode selector mechanism (60, 28, 46, 64, 65, 90, 92, 94, 96) for selection between at least two modes of operation for the plunger assembly, wherein the mode selector mechanism (60, 28, 46, 64, 65, 90, 92, 94, 96) is adjustable between two or more modes whereby movement of the plunger assembly (30) effects either movement of the agitator (50, 250) with the seal member (31, 231) or movement of the agitator (50, 250) relative to the seal member (31, 231), depending on the selected mode.

A cosmetic portioning machine is provided having a mixing chamber, with a plurality of radially-disposed inlets, each of which provides an ingredient. A piston disposed in the mixing chamber defines a mixing volume. A dasher may be disposed in the mixing chamber to mix the ingredients together in the mixing volume so as to form a cosmetic. When the cosmetic product is thoroughly mixed, the piston urges the product out of the mixing chamber and through an outlet. A moveable sealing member is configured to pass through the outlet so as to seal off fluid communication between the mixing chamber and the outlet and to urge any remaining cosmetic product through the outlet.

A device for mixing and dispensing bone material is provided. The device comprises a tubular member having an interior surface configured to receive bone material and a fluid to mix the bone material disposed within the tubular member. The tubular member is flexible and has a proximal opening configured to slidably receive a plunger, and a distal opening configured to dispense a mixed bone material from the interior surface of the tubular member. The plunger is less flexible than the tubular member. Methods of mixing and dispensing bone material are also provided.
