Abstract

Abstract A disposable mixer adapted particularly for dental work. A rotary member has at its end a set of vanes, each having a unique shape for thoroughly intermixing constituents of a mixture within a disposable container. The outermost surface of each of the vanes fits snugly against the internal walls of the container. A shaft secured to the vanes may be driven by motor device for providing the mixing motion. The end of the container may be used to force the mixture from the container after completion of the mixing process.

Claim 9
Dependent Claim 40 words
The mixing device as defined in claim 1 including a ring member attachable to said shaft member for withdrawing said rotor member from the interior of said container means simultaneously with removal of said cap means from said container means.
Claim 10
Dependent Claim 183 words
A mixing device for intermixing at least two substances comprising in combination, a rotatable shaft member; a rotor member secured to said shaft member and having a plurality of rotor blades, container means for containing said substances to be intermixed and said rotor member, the interior walls of said container means surrounding said rotor member; and cap means attachable to said container means for enclosing said substances and said rotor member in said container after said substances and rotor member are introduced into the interior of said container means, said cap means having an opening through which a portion of said shaft member supporting said rotor member extends into the interior of said container means, an exterior portion of said shaft member projecting from the exterior surface of said cap means whereby rotation of said exterior portion of said shaft member rotates said rotor member and intermixes said substances, said container means comprising a substantially thin-walled container open at one end and closed at the other end, the closed end having a score severable through application of pressure applied to said closed end.
Claim 11
Dependent Claim 183 words
A mixing device for intermixing at least two substances comprising in combination, a rotatable shaft member; a rotor member secured to said shaft member and having a plurality of rotor blades, container means for containing said substances to be intermixed and said rotor member, the interior walls of said container means surrounding said rotor member; and cap means attachable to said container means for enclosing said substances and said rotor member in said container after said substances and rotor member are introduced into the interior of said container means, said cap means having an opening through which a portion of said shaft member supporting said rotor member extends into the interior of said container means, an exterior portion of said shaft member projecting from the exterior surface of said cap means whereby rotation of said exterior portion of said shaft member rotates said rotor member and intermixes said substances, said container means comprising a substantially thin-walled container open at one end and closed at the other end, the closed end having a score severable through application of pressure applied to said closed end.
