A paint can and paint can mixing system effectively and cleanly mixes and stirs paint within the can by using a bottom mounted crank connected through the bottom of the can by a shaft which rotates a stirring member within the can. The crank is conveniently configured to be stored beneath the bottom of the paint can and to be pivoted downward when mixing of the paint within the can is desired. A shallow sidewall circumscribes the bottom of the paint can. The sidewall encloses a space in which the crank is located in its stored position. This allows easy and space saving stacking of the paint cans.

An apparatus for mixing bone cement can comprise a receiving chamber, a mixing chamber, a cannula, a base, and a piston located within the mixing chamber. The receiving chamber defining a conduit. The mixing chamber in fluid communication with the receiving chamber. The mixing chamber configured to house a first component of the bone cement. The cannula located in the receiving chamber and in fluid communication with the conduit. The base including a bladder arranged to be punctured by the cannula, the bladder configured to house a second component of the bone cement. Upon puncturing of the bladder by the cannula the second component of the bone cement passes through the conduit and the cannula into the mixing chamber. The piston configured to seal the mixing chamber upon movement of the piston from a first position relative to the conduit to a second position relative to the conduit.

Disclosed is a double chamber container. The first chamber comprises a stopper coupled to a first end and a cover coupled to a second end. The second chamber comprises a plunger coupled to one end and an open second end. The first chamber is coupled to the second chamber such that the first end of the first chamber is coupled to the second end of the second chamber.

A mixing container with an internal mixing blade has an extraction funnel, a main housing, a rotatable base cap, a mixing blade and a gear mechanism. The extraction funnel has a first end with a maximum diameter and narrowing to a second end of a minimum diameter at a neck portion. The main housing includes a mixing chamber. The rotatable base cap with an internal gear is attached to and is rotatable relative to the main housing. The mixing blade has a plurality of prongs extending from a shaft. The prongs are in the mixing chamber and the shaft extends through an opening in the main housing to inside the rotatable base cap. The gear mechanism has at least one gear, each of the at least one gears is connected to or intermeshed with the internal gear of the base cap and the gear of the shaft end.

A small, non-powered, handheld and finger-manipulated mixing device adapted for stirring or mixing liquids or liquid/solid combinations in relatively small volume containers. The mixing device has an elongated rod-like main body with an agitation member disposed on its distal end. The main body is provided with a bounded shaft segment that is bounded proximally and distally by transition shoulders of greater diameter than the bounded shaft segment, thus providing a region to receive the thumb and finger of the user to spin the main body, with the transition shoulders preventing excessive movement in the axial direction during rotation.

In some embodiments, a method of making hydrated bone material is provided, the method comprising providing a bone material in a chamber, the bone material comprising a plurality of shaped bone particles or macroparticles, each of the plurality of shaped bone particles or macroparticles having a substantially uniform size, shape and porosity; and mixing each of the plurality of shaped bone particles with liquid in the chamber under pressure so as to cause the liquid to hydrate each of the plurality of shaped bone particles to form uniformly hydrated bone material. In some embodiments, a device for mixing a bone material with a liquid is provided.

A storage and mixing device for PMMA bone cements having a cylindrical interior of the cartridge that is delimited on a front side by a cartridge head with a closed delivery opening, a plunger which is arranged to be axially movable in the cylindrical interior of the cartridge and which is spaced from the cartridge head. The plunger circumferentially rests against the inner wall of the interior, so that the plunger divides the interior of the cartridge into two sections in a gas-tight manner, a powdery first parent component of the bone cement, which is contained in the interior between the plunger and the cartridge head, a feed-through which is arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head, wherein the feed-through is connected to a fluid line in which a monomer liquid as a second parent component of the bone cement is contained or into which a monomer liquid is fillable or introducible. A filter is arrangeable in the cartridge head, in the feed-through and/or in the fluid line, wherein the filter is permeable to the monomer liquid and impermeable to the first parent component, wherein the plunger is spaced from a back side of the cylindrical interior, located opposite the front side, to an extent that, by moving the plunger in the direction of the back side, a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head, wherein the reduced pressure is able to suck the monomer liquid out of the fluid line into the interior of the cartridge.

An improved drinking vessel is a drinking cup or glass having a mixing blade located on the interior bottom having a shaft passing through the bottom of the glass to a rotationally separate portion of the glass that can be spun by hand. A screen sets inside the glass just above the mixing blade to prevent ice or other large solids in the glass from contacting the mixing blade.

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. The manual mixer includes a mixing assembly and an actuation assembly for actuating the mixing assembly. The mixing assembly includes at least a paddle portion and a plunger portion. The plunger portion is simultaneously capable of rotational movement with the paddle portion and movement upwardly or downwardly along the paddle portion. Rotation of the paddle portion serves to facilitate mixing and agitating of the materials, and downward movement of the plunger portion serves to facilitate dispensing of the materials from the manual mixer.

Agitation assemblies for a spreader having a rotatable feeding mechanism are provided that utilize the rotation of the feeding mechanism to oscillate an agitation member within the spreader. A crank is coupled to the feeding mechanism and a connecting linkage connects between the agitation member and the crank so that as a drive mechanism rotates the feeding mechanism to dispense spreading material towards a dispensing opening, the connecting linkage oscillates the agitation member. The agitation member can be a baffle or agitation plate. The oscillation of the agitation member can be pivoting or sliding oscillation.
