Abstract
Abstract The present invention is a high integrity storage container which is particularly well adapted for storage of chemical, radio-nucleide, or other types of waste materials. The body portion will typically be of right rectangular configuration having an open top. An inwardly oriented flange is located completely around the upper periphery of the container body where it acts with a corresponding mating surface on a lid to provide sealing surfaces. A key element is a novel folded gasket located between the mating surfaces of the body and lid. This is oriented with the fold portion toward the outer periphery of the container where it has minimum exposure to the contents. Preferably, the lips or edges of the gasket are bonded to the lid and body flange by a pressure sensitive adhesive to form a tight seal. A resilient strip is located within the folded area of the gasket to urge the adhesive coated surfaces into intimate contact with the mating surfaces of the lid and body flange. The use of the inwardly located flange allows close contact between adjacent containers in a storage area so that waste space is minimized. The folded gasket acts like a bellows to maintain the seal integrity if stresses during use cause minor displacement between the container body and lid.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
177 words
A high integrity storage container which comprises: a. an open-topped container body means having an inwardly oriented flange means around and substantially contained within the upper periphery thereof b. a lid means having a coextensive mating surface for the container flange means; c. means for securing the lid to the container; and d. a longitudinally folded flexible gasket means located between the mating surfaces of the container and lid means with the fold portion oriented toward the outer perphery of the container to as to be essentially out of contact with the contents of the container, the edge portions of the gasket means opposite the fold are adhesive coated to bond the gasket means to the mating surfaces of the container and lid means, the gasket means further having a compressible resilient means contained within the folded area for urging the adhesive coated surfaces into intimate contact with the mating surfaces, whereby if misalignment or distortion occurs between the container and lid means during use the gasket means can adjust to maintain the integrity of the seal.
Claim 2
Dependent Claim
177 words
A high integrity storage container which comprises: a. an open-topped container body means having an inwardly oriented flange means around and substantially contained within the upper periphery thereof b. a lid means having a coextensive mating surface for the container flange means; c. means for securing the lid to the container; and d. a longitudinally folded flexible gasket means located between the mating surfaces of the container and lid means with the fold portion oriented toward the outer perphery of the container to as to be essentially out of contact with the contents of the container, the edge portions of the gasket means opposite the fold are adhesive coated to bond the gasket means to the mating surfaces of the container and lid means, the gasket means further having a compressible resilient means contained within the folded area for urging the adhesive coated surfaces into intimate contact with the mating surfaces, whereby if misalignment or distortion occurs between the container and lid means during use the gasket means can adjust to maintain the integrity of the seal.
Claim 3
Dependent Claim
15 words
The container of claim 1 in which the compressible resilient means is a polymeric foam.
Claim 4
Dependent Claim
14 words
The container of claim 1 in which the adhesive is a pressure sensitive material.
Claim 5
Dependent Claim
12 words

Claim 6
Dependent Claim
15 words
The container of claim 1 in which the container means is of right rectangular configuration.
Claim 7
Dependent Claim
35 words
The container of claim 5 in which one edge of the lid means is attached to the container means by a hinge which is substantially the full length of the corresponding edge of the container.
Claim 8
Dependent Claim
28 words

Claim 9
Dependent Claim
48 words
The container of claim 7 in which the other edges are secured by a plurality of hinge-like fasteners, each of which is substantially shorter than the length of the edge to which it is attached, the hinge pins of the fasteners being removable to permit opening the lid.
Claim 10
Dependent Claim
19 words
The container of claim 6 in which the other edges are secured by opposed, elongated interlocking flexible hook means.
Claim 11
Dependent Claim
36 words
The container of claim 6 in which the other edges are secured by a plurality of opposed elongated interlocking flexible hook means each of which is substantially shorter than the edge to which it is attached.
Claim 12
Dependent Claim
15 words

Claim 13
Dependent Claim
201 words
A high integrity storage container resistant to leakage which comprises: a. an open top container body means of right rectangular configuration, said means having an inwardly oriented flange around and substantially contained within the upper periphery thereof; b. a lid means having a coextensive mating surface for the container flange, said lid means being attached to the container means by a hinge which is substantially the full length of one edge of the container; c. a plurality of securing means for locking the lid means to the container means, the securing means being in the form of hinge-like fasteners with removable hinge pins to permit opening the lid; and d. a longitudinally folded flexible gasket means located between the mating surfaces of the container and lid means with the fold portion oriented toward the outer periphery of the container so as to be essentially out of contact with the contents of the container, the edge portions of the gasket means opposite the fold being adhesive coated to bond the gasket means to the mating surfaces, whereby if misalignment or distortion occurs between the container and lid means during use, the gasket means can adjust to maintain the integrity of the seal.
Claim 14
Dependent Claim
