Abstract
Abstract An hermetic sealing system for openings in an enclosure. In one form a cover is provided having an edge fitting over a container having a lip with the cover fitting loosely over the lip of the container. A flexible gasket member is provided between the lip of the container and the edge of the cover. A metal band is provided encircling the mating portions of the container and the cover compressing the flexible gasket between such mating portions. A mastic such as a room temperature cure epoxy is forced into the space between the metal band and the container, the mastic also filling the space between the edge of the cover and lip of the container and moving into contact with the flexible gasket. The mastic is then cured, firmly sealing the cover to the container. If desired, the metal band may be treated with a release agent and then removed after the mastic is cured. In another form, a bushing member surrounds an opening in a wall and is bolted to the wall. A channel in the base of the bushing carries a flexible gasket member compressed against the wall member about the opening. A second channel in the base of the bushing is filled with a mastic which when cured seals the bushing to the wall member.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
74 words
An hermetic sealing system for joining a cover to a container in which said cover and said container have overlying surfaces comprising a flexible gasket member compressed between said overlying surfaces, a metal band member surrounding said overlying surfaces and pressing said overlying surfaces into sealing engagement with said gasket and a room temperature curing plastic material completely filling all the spaces between said metal band and said overlying surfaces and contacting said gasket.
Claim 2
Dependent Claim
74 words
An hermetic sealing system for joining a cover to a container in which said cover and said container have overlying surfaces comprising a flexible gasket member compressed between said overlying surfaces, a metal band member surrounding said overlying surfaces and pressing said overlying surfaces into sealing engagement with said gasket and a room temperature curing plastic material completely filling all the spaces between said metal band and said overlying surfaces and contacting said gasket.
Claim 3
Dependent Claim
117 words
An hermetic sealing system for sealing an opening in a container in which a sealing member is provided overlying said opening, said sealing member and said container having overlying surfaces comprising a channel formed in one of said overlying surfaces, a flExible gasket member secured in said channel and compressed between said overlying surfaces, a space provided between said overlying surfaces extending exteriorly of said gasket to the edge of said overlying surfaces, means secured at said edge of said overlying surfaces to close said space therebetween and a room temperature curing plastic material completely filling said space between said overlying surfaces and contacting said gasket and said means secured to said edge of said overlying surfaces.
Claim 4
Dependent Claim
117 words
An hermetic sealing system for sealing an opening in a container in which a sealing member is provided overlying said opening, said sealing member and said container having overlying surfaces comprising a channel formed in one of said overlying surfaces, a flExible gasket member secured in said channel and compressed between said overlying surfaces, a space provided between said overlying surfaces extending exteriorly of said gasket to the edge of said overlying surfaces, means secured at said edge of said overlying surfaces to close said space therebetween and a room temperature curing plastic material completely filling said space between said overlying surfaces and contacting said gasket and said means secured to said edge of said overlying surfaces.
Claim 5
Dependent Claim
49 words
An hermetic sealing system as claimed in claim 2 in which said sealing member is a cover for said container and said means secured at said edge of said overlying surfaces is a metal band surrounding said overlying surfaces and pressing said overlying surfaces and compressing said gasket therebetween.
Claim 6
Dependent Claim
51 words
An hermetic sealing system as claimed in claim 2 in which said sealing member is a bushing, said channel is formed in said bushing and said means closing said space between said overlying surfaces is a dam member mounted on said container surrounding and secured to the edge of said bushing.
Claim 7
Dependent Claim
104 words
An hermetic sealing system for sealing an opening in a container in which a bushing member is provided overlying said opening with said bushing and said container having overlying surfaces comprising a first channel member formed in said bushing and completely surrounding said opening in said container, a flexible gasket member mounted in said first channel and compressed between said overlying surfaces, a second channel formed in said bushing completely surrounding said first channel, at least one opening extending from the exterior of said bushing to said second channel and a room temperature curing plastic material completely filling said second channel and said opening.
Claim 8
Dependent Claim
104 words
An hermetic sealing system for sealing an opening in a container in which a bushing member is provided overlying said opening with said bushing and said container having overlying surfaces comprising a first channel member formed in said bushing and completely surrounding said opening in said container, a flexible gasket member mounted in said first channel and compressed between said overlying surfaces, a second channel formed in said bushing completely surrounding said first channel, at least one opening extending from the exterior of said bushing to said second channel and a room temperature curing plastic material completely filling said second channel and said opening.
Claim 9
Independent Claim
94 words
A method of making an hermetic seal between a cover and a container comprising, a. placing a flexible gasket member on the outer surface of the lip of said container, b. placing said cover on said container with a surface of the cover overlying a mating surface of said container, c. placing a metal band in overlying relationship completely surrounding said overlying surfaces and tightening said metal band to compress said gasket between said overlying surfaces and d. completely filling the spaces between said cover band and said overlying surfaces with a plastic material.
Claim 10
Independent Claim
94 words
A method of making an hermetic seal between a cover and a container comprising, a. placing a flexible gasket member on the outer surface of the lip of said container, b. placing said cover on said container with a surface of the cover overlying a mating surface of said container, c. placing a metal band in overlying relationship completely surrounding said overlying surfaces and tightening said metal band to compress said gasket between said overlying surfaces and d. completely filling the spaces between said cover band and said overlying surfaces with a plastic material.
Claim 11
Dependent Claim
28 words
The method of making an hermetic seal as set forth in claim 6 in which said flexible gasket is vulcanized in place to the lip of said container.
