Abstract
Abstract A reinforced filament tape for securing and releasing meeting edges of a container or articles within a container, comprises a flexible backing ribbon with a pressure sensitive adhesive on one side. On the other side of the backing ribbon is a binding layer overlayed by a plurality of reinforcing filaments and a releasing layer. The filaments are contacted with a filament coating and remain securely positioned in the binding layer.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
96 words
A reinforced filament tape comprising: an elongate flexible backing ribbon having first and second mutually parallel planar surfaces; an adhesive layer overlaying and co-extensive with said first planar surface; a binding layer overlaying and co-extensive with said second planar surface; a plurality of spaced mutually parallel reinforcing fiber filaments overlaying said binding layer, said fiber filaments being contacted and penetrated with a filament coating to prevent said fiber filaments from separating from said binding layer; and a releasing layer overlaying and contoured to the shape of said filaments for facilitating unreeling of said reinforced filament tape.
Claim 2
Dependent Claim
96 words
A reinforced filament tape comprising: an elongate flexible backing ribbon having first and second mutually parallel planar surfaces; an adhesive layer overlaying and co-extensive with said first planar surface; a binding layer overlaying and co-extensive with said second planar surface; a plurality of spaced mutually parallel reinforcing fiber filaments overlaying said binding layer, said fiber filaments being contacted and penetrated with a filament coating to prevent said fiber filaments from separating from said binding layer; and a releasing layer overlaying and contoured to the shape of said filaments for facilitating unreeling of said reinforced filament tape.
Claim 3
Dependent Claim
41 words
A reinforced filament tape as defined in claim 1 wherein: said reinforcing filaments are contacted with a hard resinous filament coating to permit said filaments to be cracked by bending the tape upon itself to facilitate lateral tearing of the tape.
Claim 4
Dependent Claim
20 words
A reinforced filament tape as defined in claims 1 or 2 wherein: said filaments are saturated with said filament coating.
Claim 5
Dependent Claim
30 words
A reinforced filament tape as defined in claimn 1 wherein: said tape additionally comprises a continuous layer of said filament coating between said reinforcing fiber filaments and said releasing layer.
Claim 6
Dependent Claim
26 words
A reinforced filament tape as defined in claim 1 wherein: the diameter of each of said filament is greater than the thickness of said releasing layer.
Claim 7
Dependent Claim
35 words
A reinforced filament tape as defined in claim 4 wherein: the diameter of each of said filament is greater than the combined thickness of said releasing layer and said continuous layer of said filament coating.
Claim 8
Dependent Claim

Claim 15
Dependent Claim
29 words
A reinforced filament tape as defined in claims 1 or 4 wherein: said filament coating is applied to said filament in the form of an isopropanol, toluene polyamide solution.
Claim 16
Dependent Claim
31 words
A reinforced filament tape as defined in claims 1 or 4 wherein: said filament coating is applied to said filament in the form of an aqueous solution of acrylic acid-ethylene copolymer.
Claim 17
Dependent Claim
34 words
A reinforced filament tape as defined in claims 1 or 4 wherein: said releasing layer material is selected from the group consisting of paraffinics, octadecane-polyvinyl alcohol polymers, silicone polymers and copolymers, polyesters and polyamides.
