Abstract
Abstract Fasteners such as clips and seals are each provided with a body of foam in its open zone. The foam is carried into a clinched joint to form a tight durable joint. The foam may be used to unitize a stack of like fasteners, thereby to provide an easily handled, somewhat bendable and pliable fastener stack.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
A fastener stack comprising a plurality of similarly shaped adjacent metal fasteners, each of which the plurality adapted to hold elongate members to each other, each fastener defining an open internal zone adapted to receive elongate members intermediate their ends and adapted to be closed to embrace and hold said elongate members, each fastener providing a body of given volume of compressible foam material fast therewithin and disposed within at least a portion of said open zone, said body being positioned to confront said elongate members, each of said fasteners being readily severable from said stack and proportioned to carry said body of foam material therewith, whereby when a severed fastener is closed about said elongate members, foam material is displaced and compressed within said closed fastener to reduce very substantially the volume of said foam material and to place foam material in intimate retentive engagement with said elongate members.
Claim 2
Dependent Claim
150 words
A fastener stack comprising a plurality of similarly shaped adjacent metal fasteners, each of which the plurality adapted to hold elongate members to each other, each fastener defining an open internal zone adapted to receive elongate members intermediate their ends and adapted to be closed to embrace and hold said elongate members, each fastener providing a body of given volume of compressible foam material fast therewithin and disposed within at least a portion of said open zone, said body being positioned to confront said elongate members, each of said fasteners being readily severable from said stack and proportioned to carry said body of foam material therewith, whereby when a severed fastener is closed about said elongate members, foam material is displaced and compressed within said closed fastener to reduce very substantially the volume of said foam material and to place foam material in intimate retentive engagement with said elongate members.
Claim 3
Dependent Claim
27 words
A fastener stack in accordance with claim 1 wherein the open zone of each fastener is concave and said foam material is fast with the concave surface.
Claim 4
Dependent Claim
16 words
A fastener stack in accordance with claim 1 wherein said foam material is a resilient foam.
Claim 5
Dependent Claim
25 words
A fastener stack in accordance with claim 1 wherein said fasteners are U-shaped clip members adapted to be closed and crimped about said elongate members.
Claim 6
Dependent Claim
31 words
A fastener stack in accordance with claim 1 in which said bodies of foam material are continuous and integral, thereby to secure said fasteners to each other in said fastener stack.
