Patent number: 9211168Abstract: Provided is a capsule for storing and dispensing dental material. The capsule comprises a cartridge for the dental material, and a nozzle. The nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material. One of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, wherein the bearing member and bearing shell form a pivot. Upon pivoting the nozzle from the first to the second position, the seal between the bearing member and the bearing shell is improved.Type: GrantFiled: December 7, 2012Date of Patent: December 15, 2015Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Bruce R.

Patent number: 7214435Abstract: A mill blank assembly for a dental prosthesis includes a milling section and a support section for supporting the assembly in a milling machine. In certain embodiments, the milling section is adhesively bonded to the support section by a direct chemical bond that provides enhanced resistance to unintentional detachment of the milling section from the support section during a subsequent machining operation. Optionally, the support section includes a passageway that receives a quantity of flowable dental restorative material used to make the milling section, such that the restorative material that is located in the passageway provides additional resistance when hardened to unintentional detachment of the milling section from the support section.Type: GrantFiled: October 3, 2003Date of Patent: May 8, 2007Assignee: 3M Innovative Properties CompanyInventors: Darin J. Meyertholen, Robert M. Biegler, Ryan B. Quast, Dean K. Reidt, John R. Cheney

Patent number: 7131784Abstract: A container includes, in one embodiment, an outer housing holding a first mass of a first component of a composition, an inner housing holding a second mass of a second component of the composition, and a seal. The first component is a liquid and the mass of the second component conforms to a bottom and side wall of the inner housing. An interference fit exists between the outer housing and the inner housing such that the inner housing seals the first mass within the first chamber. The inner housing has an aperture in a side wall of the second chamber.Type: GrantFiled: March 11, 2004Date of Patent: November 7, 2006Assignee: 3M Innovative Properties CompanyInventors: Robert Lee, Darin J.
