US Patent:

41390300, Feb 13, 1979

Filed:

Jan 17, 1977

Appl. No.:

5/759816

Inventors:

Manfred F. Schroeder - Point Pleasant Beach NJ
Joseph G. Biondo - Watchung NJ
Joseph Aliotta - Staten Island NY

Assignee:

Engelhard Minerals & Chemicals Corporation - Iselin NJ

International Classification:

B65B 130

US Classification:

141 98

Abstract:

A device for dispensing ingredients, such as the ingredients for a dental amalgam, has a handle portion and a head portion formed of mating parts with the handle angulated to the head and formed for convenient gripping by the user's hand. A slide mounted in the head slides laterally when pushed by the user's thumb to transport measured ingredients to a common aperture for delivery into a container. The container, when put in place, releases a latch that holds the slide normally in measuring position and prevents transport of the ingredients unless the container is in position to catch them. Adjustment of a measuring chamber for liquid mercury, to accurately proportion it, is by a valve having an end projecting, more or less, into a chamber, so as to vary the volume of the chamber. The position of the valve is controlled by a rectilinearly movable cam whose position may be fixed by a lock nut which normally is inaccessible in a recess in the head portion.

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.

International Classification:

G01F 1110

US Classification:

222307

Abstract:

A body member has an internally screw-threaded socket or recess to receive the neck of a container, and a port adapted in one position to communicate with a transverse passage or measuring chamber in a slidable measuring and dispensing member which is movable into another position wherein the measuring chamber communicates with a discharge passage in the body. A spring biased valve member is slidable within an axial bore in the measuring and dispensing member and is under control of a slidable cam abutting the valve member, the cam being assembled in a slot in the measuring and dispensing member and held there by a stop member rotatably mounted on the end of the measuring and dispensing member.
