Abstract: A batch pack for silver filings is employed in the preparation of dental amalgam in a laboratory mixing apparatus. The batch pack comprises a foil bag which can be destroyed by the mixing vibration and a briquette or tablet of silver filings. The density of the briquette of silver filings is not more than about 8 gram per cubic centimeters or a pore volume of about 20 percent of the volume of the briquette.

Abstract: A two-piece, two chamber self-activating capsule having mercury in one chamber and metal powder in the other. In use, the capsule is shaken and the resulting force due to the inertia of the mercury forces its way through a normally-closed valve into the metal powder chamber, whereby the metal powder and mercury become triturated by the shaking and form dental amalgam for filling teeth. A pestle may be included to facilitate mingling and triturating the amalgam components.

Abstract: The reactive precursors of a dental amalgam are stored in separate chambers of a disposable dental capsule which allows the precursors to be mixed when desired with no special manipulation of the capsule by the user. The capsule comprises a closed cylindrical container divided into two noncummunicating, internal chambers by a movable, flexible disk. The dental capsule may contain mercury in one chamber and silver powder and a mixing pestle in the other chamber. When placed in a dental amalgamator, the mixing pestle drives the flexible disk to the end of the vessel of the container forcing the mercury to flow around the edges of the disk and to mix with the silver powder, thereby forming the dental amalgam.

Abstract: Mixing container for manufacturing dental preparations with a first part that contains a powdered material and a second, separable part that contains a liquid in a destructible foil bag.The bag is destroyed by a movable pestle. The resistance to ripping of the foil bag and the pressure impulse acquired by the pestle when the container is shaken in an oscillating mixer are proportioned to result in the destruction of the bag when struck by the pestle. The pestle has elevations and guides in preferred embodiments.

Abstract: A self-actuating dental capsule is provided which includes a rupturable container for the liquid component of a dental amalgam. The container is held in the capsule by a retaining sleeve or disk so that the amalgam can be immediately used by the dentist without the need to separate the container from the amalgam. The container and the retaining means can be formed as a unit prior to placement in the capsule.

Abstract: The present invention relates to a capsule for storing and vibration mixing of two component materials for dental application, particularly of dental amalgam components. The capsule encloses a mixing space in which a first component and a pestle are disposed. The pestle is in the form of a hollow body with a removable cover. The pestle serves as a container for a second component and has at least one opening. The opening permits the exit of the second component which opening is rendered passable as a result of a mixing vibration movement.

Abstract: A sample vial for use in comminuting and blending material samples for spectrochemical analysis has a vial body section of a cylindrical configuration with a closed recessed bottom end having an inner concave semi-spherical surface. The body section has an opened top end with an inner flange surrounding the same. A cover member is also of a cylindrical configuration and has a closed recessed top end with the inner surface of the cover member of a concave semi-spherical shape. The cover member has an inner peripheral flange for insertion into an opened top end of the vial body section to form a friction fit closure which acts as a seal to prevent particle material from leaking out of the vial. The composite internal hollow of the vial provides a smooth uniform surface to allow a pestle to traverse the same when the vial is vibrated.

Abstract: In a dual component packing of the type consisting of a flexible bag, which contains the single liquid components in respective separate compartments, from which they may be brought together into a common mixing compartment by exterior manipulation, a mixing stick is mounted inside the packing so as to be seizable at one end by squeezing together the bag sheet material thereabout, whereafter the free end of the mixing stick by exterior manipulation can be moved around in the mixing compartment for effectively stirring and mixing the combined liquid components. Exterior pressure manipulations on the bag itself will be superfluous, and for this reason a packing of a simple flat bag type may be bottomwise designed so as to assume a cup shaped form when placed on a substantially planar support surface, whereby an effective mixing stirring by means of the said mixing stick is achievable.

Abstract: A capsule for the storage and vibration mixing of two components, particularly for dental uses comprises a mixing chamber in which one of the components is stored, the chamber having an aperture which is closed by means of a removable closure member and a foil bag which can be ruptured without disintegration by the mixing movement is housed in the mixing chamber and contains the other component in liquid form. The liquid component is a high specific gravity liquid such as mercury and the closure member is sealingly secured to that part of the capsule which forms the mixing chamber by a seal which has a predetermined breaking strength, formed conveniently by a weld or adhesive. Externally the closure member presents a cylindrical socket to which can be fitted a cylindrical lever for the purpose of breaking the seal to remove the closure member and allow access to the interior of the mixing chamber for withdrawal of the mix.

Abstract: Water and a hydrated salt are both present to reduce the flammability of a flammable resin system, e.g. a capsule having two compartments each containing an interactive component and for use in e.g. a mine.

Abstract: A cartridge assembly for applying multicomponent curable mixtures to a substrate with at least one curable component in a pressure rupturable container, a liquid-permeable mixer assembly at one end of said container, means for selectively rupturing said container adjacent the mixer assembly, and nozzle means adjacent the exit end of said mixer assembly.

Abstract: The instant invention relates to disposable capsules which contain coreactive components in separate chambers and means for automatically combining and mixing said coreactive components prior to opening the capsule. The instant disposable capsules may contain dental amalgam precursors such as mercury and silver which may be combined and mixed merely by placing such capsule in a dental amalgamator. The disposable capsules comprise a hollow cylindrical section closed at one end and having an internal constriction spaced from the other end, and a movable insert comprising a stem having an upper portion inserted through and frictionally engaging said constriction and a flange extending outwardly about the lower end of said stem and frictionally engaging the inner wall of the hollow cylindrical section, whereby said flange initially divides said cylinder into two noncommunicating chambers.

Abstract: A device for storing, transporting and mixing reactive ingredients, such as mercury and silver for dental amalgam, includes a thin, rupturable membrane dividing the two chambers of a capsular container into two non-communicating closed compartments, one for each of the reactive ingredients, the chamber of larger volume (major chamber) also including a pestle. Unlike conventional devices of this type, the membrane is ruptured substantially completely intact, i.e. without presenting any loosened or torn fragments of the membrane which could contaminate the mixed ingredients simply by inserting the capsule in an amalgamator or similar vibrating or shaking device. Since no manipulation of the capsule, such as telescoping, bending, twisting etc is required, mixing of the components can be performed with a minimum amount of effort.

Abstract: A small two-part capsule for receiving and for storing separately individual ingredients and for mixing them together has two cavities in one part which receive the ingredients separately. The cavities are sealed by the other part via a screw thread connection. When the capsule is inverted and the connection is loosened, the ingredients from one cavity flows into the other. Novel sealing means is provided between the two parts.

Abstract: A compartmented package is described comprising a unitary body member having a cavity therein adapted to contain at least two co-reactive components separated into compartments by means of an elongated mixing tool. The top portion of the cavity is closed or covered by means of an openable cover member (e.g. a transparent plastic film removably secured to the unitary body member).
