Abstract
Abstract An improved solderable hermetically sealed container and method for sealing same is provided which comprises in a preferred embodiment, a hollow container having a solderable peripheral surface defining the opening to the container, a thin, solderable metallic membrane covering the opening and solderable surface of the container, a solder seal interfacing the membrane and the solderable surface of the container, and a protective lid covering the membrane and being removably attached to the container body. If desired, an adhesive seal between the membrane and protective lid may be provided to protect the membrane from excessive vibration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A solderable, hermetically sealed reuseable container which comprises: a. a container body defining a cavity therein and presenting a solderable surface defining an opening for said container: b. a thin, reuseable, solderable metallic membrane for hermetically sealing said opening by interfacing with said solderable surface by the application of heat around the periphery of said membrane; c. a solder seal interfacing said membrane and said solderable surface; d. a protective plate covering said membrane; and e. means for removably attaching said protective plate to said container body.
Claim 2
Dependent Claim
87 words
A solderable, hermetically sealed reuseable container which comprises: a. a container body defining a cavity therein and presenting a solderable surface defining an opening for said container: b. a thin, reuseable, solderable metallic membrane for hermetically sealing said opening by interfacing with said solderable surface by the application of heat around the periphery of said membrane; c. a solder seal interfacing said membrane and said solderable surface; d. a protective plate covering said membrane; and e. means for removably attaching said protective plate to said container body.
Claim 3
Dependent Claim
27 words
The container as recited in claim 1 further comprising a layer of adhesive between said protective plate and said membrane for vibration dampening said plate and membrane.
Claim 4
Dependent Claim
69 words
In a method of hermetically sealing a container having a hollow body portion and presenting a solderable surface defining an opening thereinto, an improvement comprising: a. overlaying a thin, reuseable, solderable metallic membrane onto said solderable surface; b. soldering said membrane to said solderable surface by the application of heat to said membrane around the periphery thereof; and c. attaching a protective cover to said container over said membrane.
Claim 5
Dependent Claim
69 words
