Abstract

Abstract 1. A tamper resistant container including a main container body and a separable cover each having mating surfaces and defining a complete enclosure when said mating surfaces are placed in abutting relationship, at least one wall carried electrical circuit formed within respective cover and main body walls, conductive tabs placed in spaced relationship upon the mating surfaces of said cover and main container body, means for electrically connecting said circuits to said spaced tabs, means for electrically connecting corresponding tabs of said main container body and said cover, said connecting means including a wet silver film positioned between respective tabs with said films being air curable to insure completion of an electrical circuit between said main container body and said separable cover, and means for energizing said circuit whereby attempts to penetrate said container result in changing the electrical characteristics of said circuit.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 142 words
A tamper resistant container including a main container body and a separable cover each having mating surfaces and defining a complete enclosure when said mating surfaces are placed in abutting relationship, at least one wall carried electrical circuit formed within respective cover and main body walls, conductive tabs placed in spaced relationship upon the mating surfaces of said cover and main container body, means for electrically connecting said circuits to said spaced tabs, means for electrically connecting corresponding tabs of said main container body and said cover, said connecting means including a wet silver film positioned between respective tabs with said films being air curable to insure completion of an electrical circuit between said main container body and said separable cover, and means for energizing said circuit whereby attempts to penetrate said container result in changing the electrical characteristics of said circuit.
Claim 2
Dependent Claim 142 words
A tamper resistant container including a main container body and a separable cover each having mating surfaces and defining a complete enclosure when said mating surfaces are placed in abutting relationship, at least one wall carried electrical circuit formed within respective cover and main body walls, conductive tabs placed in spaced relationship upon the mating surfaces of said cover and main container body, means for electrically connecting said circuits to said spaced tabs, means for electrically connecting corresponding tabs of said main container body and said cover, said connecting means including a wet silver film positioned between respective tabs with said films being air curable to insure completion of an electrical circuit between said main container body and said separable cover, and means for energizing said circuit whereby attempts to penetrate said container result in changing the electrical characteristics of said circuit.
Claim 3
Dependent Claim 44 words
The apparatus as claimed in claim 1 further including latch means acting to mechanically couple said separable cover to said main container body wherein latching of said latch means enhances completion of the electrical circuit through said tabs and the sandwiched wet silver film.
Claim 4
Dependent Claim 58 words
The apparatus as claimed in claim 1 wherein said container wall includes electrical connecting means in the form of transverse conductive members passing through said wall with a portion of said transverse conductors within said wall proper being suitably curved to effect misalignment between the terminal portions of said conductive members exteriorly and interiorly of said wall member.
