Abstract
Abstract A lid to be bonded to provide a hermetic seal has bonded thereto a thermally autoregulating heater for activating a heat activated sealing and bonding material to produce the desired seal between the lid and box wherein the temperature is regulated to produce heat in a range that does not change delicate objects that may be heated in the box and wherein the energizing element of the heater may be removed or replaced at will.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
70 words
A member to be secured to another member by means of a heat activated sealant energized by an integral temperature autoregulating heater comprising a member having a first surface and a second surface, a temperature autoregulating heating element bonded to said first surface, an energizing circuit for said heating element removably adhered to said heating element, and means adapted to connect said energizing circuit to a source of alternating current.
Claim 2
Dependent Claim
70 words
A member to be secured to another member by means of a heat activated sealant energized by an integral temperature autoregulating heater comprising a member having a first surface and a second surface, a temperature autoregulating heating element bonded to said first surface, an energizing circuit for said heating element removably adhered to said heating element, and means adapted to connect said energizing circuit to a source of alternating current.
Claim 3
Dependent Claim
19 words
The combination according to claim 1 wherein said member is a cover to be hermetically sealed to a box.
Claim 4
Dependent Claim
47 words
The combination according to claim 2 wherein said cover is adapted to contact said box along a defined area of said second surface of said cover, and wherein said heater element is disposed on said first surface of said cover opposite said area on said second surface.
Claim 5
Dependent Claim
19 words
The combination according to claim 2 or claim 3 wherein said heater element is permanently bonded to said cover.
Claim 6
Dependent Claim
20 words
The combination according to claim 2 or claim 3 wherein said energizing circuit is inductively coupled to said heater element.
Claim 7
Dependent Claim
25 words
The combination according to claim 2 or claim 3 further comprising means for bringing said area of said second surface onto contact with a sealant.
Claim 8
Dependent Claim
28 words
The combination according to claim 6 wherein said heater element is a magnetic material having a Curie temperature in a range required to activate said thermal activated sealant.
Claim 9
Dependent Claim
78 words
In combination, a receptacle and a cover adapted to be adhered to said receptacle in hermetic sealing relation, said combination comprising a thermally autoregulating heater element secured to a first surface of said cover, a heater element energizing circuit removably bonded to said heater element, said cover adapted to contact said receptacle over a specified area of a second surface of said cover, and a sealant disposed between the areas of contact between said cover and said receptacle.
Claim 10
Dependent Claim
78 words
In combination, a receptacle and a cover adapted to be adhered to said receptacle in hermetic sealing relation, said combination comprising a thermally autoregulating heater element secured to a first surface of said cover, a heater element energizing circuit removably bonded to said heater element, said cover adapted to contact said receptacle over a specified area of a second surface of said cover, and a sealant disposed between the areas of contact between said cover and said receptacle.
Claim 11
Dependent Claim
25 words
The combination according to claim 8 wherein said heater element is disposed on said first surface of said cover opposite said specified areas of contact.
Claim 12
Dependent Claim
