Abstract: Capsule (10) for two or more components of a material which are to be mixed together, comprising a cartridge (11) comprising an outlet (12), a first component chamber (13) for containing a first component, and a second component chamber (14) for containing a second component, the two chambers (13, 14) opening into the outlet (12); and a piston (15) which at least with its front end sits in the cartridge (11), lies with its rear end outside the component chambers (13, 14) and, when it is pushed forwards, presses the two components out of their component chambers (13, 14).

Abstract: The invention includes a delivery system for a composition made of two or more components, the assembly of a container for use in the system, a method for providing a composition, and a delivery system including an applicator and container. In one embodiment, the container includes an outer housing holding a first mass of a first component of the 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.

Abstract: Methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles are disclosed. In various embodiments, the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner. The mold body may also form the package of the hardenable dental article formed within the mold cavity. In other embodiments, the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.
