Abstract

A gasket retainer that is absent sharp corners, has apertures of reasonable dimensional tolerance, and may be conveniently made by a variety of manufacturing processes. The retainer is made from thin flat springy material that readily returns to form after slight bending. Representative gasket capturing apertures are of smoothly non-convex outline with major dimension sufficiently large to allow passage of a ring shaped gasket turned on edge and minor dimension sufficiently small to engage, on approximately opposite circular segments that each engage along less than one third of a gasket circumference, a cavity or groove on the outside diameter periphery of the gasket turned flat parallel to the retainer material sheet. Fasteners may be retained by similar apertures.

Claims6

Dependent claims

A gasket retainer for use in a fluid delivery system, comprising:

a base member formed of a substantially flat and planar sheet of material;
and
a gasket-capturing aperture formed in the base member, the gasket-capturing aperture comprising an elliptical shape with a major diameter and minor diameter wherein the major diameter is greater than the minor, the gasket-capturing aperture having a symmetry about a minor axis and symmetry about a perpendicular major axis, wherein a first pair of matching curved sides, without any inward projecting portions, are at opposite ends of the minor axis, and a second pair of matching differently curved sides, without any inward projecting portions, are at opposite ends of the major axis, the first curved sides being sufficiently close to each other so as to engage a cavity, groove, or thread on an outside diameter of a circular gasket,
wherein the base member and the gasket-capturing aperture each comprise non-sealing surfaces and wherein the circular gasket is removably coupled with the gasket-capturing aperture.
