Threaded closure assemblies having a high applied torque tolerance

摘要

The present application is directed to closure assemblies, and particularly closure assemblies for closing an opening in a vessel. In particular embodiments, the closure assemblies described herein can have a first ring having a top surface, an inner surface and an outer surface, wherein the outer surface comprises threading, wherein the first ring comprises a first flange having a top surface extending radially inward from the inner surface of the first ring a distance of FL, and wherein the top surface of the first flange is spaced apart from the top surface of the first ring by a distance FH, and wherein a ratio of FH:FL is greater than 1.

主权项

1. An assembly for closing an opening in a vessel, the assembly comprising:
a first ring having a top surface, an inner surface and an outer surface, wherein the outer surface comprises threading, wherein the first ring comprises a first flange having a top surface extending radially inward from the inner surface of the first ring a distance of FL, wherein the top surface of the first flange is spaced apart from the top surface of the first ring by a distance FH, and wherein a ratio of FH:FL is greater than 1, wherein a cavity is defined by the top surface of the first flange and the inner surface of the first ring above the first flange, and wherein the cavity is open and unfilled; a second ring having an inner surface and an outer surface, wherein the inner surface comprises threading; wherein the threading on the first ring and the threading on the second ring are adapted to engage with each other; and wherein the first ring is a split ring.
