Claim 1
Independent Claim
201 words
A fluid-tight slide fastener comprising a pair of fastener halves (10, 10; 20, 20) each including: a support tape (11, 21); a row of continuous coupling elements (12) extending along an innermost longitudinal edge of said tape (11, 21) on one side of the latter; a connecting means (14) for securing said row of coupling elements (12) to said tape (11, 21); and an elastomeric seal member (15) extending on the other side of said tape (11, 21) in a substantially coextensive relation and having a longitudinal contact edge portion (16) transversely projecting beyond a median plane of symmetry (P) defined by said slide fastener halves (10, 10; 20, 20) in engagement, said plane being perpendicular to a general plane of said seal member (15), said longitudinal contact edge portion (16) being adapted to bear against an opposed longitudinal contact edge portion (16) of the mating fastener half (10, 20); characterized in that said support tape (11, 21) includes a longitudinal ridge (18', 28) substantially defining said longitudinal edge of said tape (11, 21) and projecting from said other side of said tape (11, 21) for supporting said contact edge portion on top and innermost sides of said ridge (18', 28).
Claim 2
Dependent Claim
201 words
A fluid-tight slide fastener comprising a pair of fastener halves (10, 10; 20, 20) each including: a support tape (11, 21); a row of continuous coupling elements (12) extending along an innermost longitudinal edge of said tape (11, 21) on one side of the latter; a connecting means (14) for securing said row of coupling elements (12) to said tape (11, 21); and an elastomeric seal member (15) extending on the other side of said tape (11, 21) in a substantially coextensive relation and having a longitudinal contact edge portion (16) transversely projecting beyond a median plane of symmetry (P) defined by said slide fastener halves (10, 10; 20, 20) in engagement, said plane being perpendicular to a general plane of said seal member (15), said longitudinal contact edge portion (16) being adapted to bear against an opposed longitudinal contact edge portion (16) of the mating fastener half (10, 20); characterized in that said support tape (11, 21) includes a longitudinal ridge (18', 28) substantially defining said longitudinal edge of said tape (11, 21) and projecting from said other side of said tape (11, 21) for supporting said contact edge portion on top and innermost sides of said ridge (18', 28).
Claim 3
Dependent Claim
40 words
A fluid-tight slide fastener according to claim 1, characterized in that said connecting means is made of threads having a portion (14') thereof disposed adjacent to said longitudinal ridge (18', 28) and remotely from said longitudinal contact edge portion (16).
Claim 4
Dependent Claim
42 words
A fluid-tight slide fastener according to claim 1, charaterized in that said tape is made of a knitted fabric(ll) including a plurality of wales (18) on at least said other side thereof, one of said wales providing said longitudinal ridge portion (18').
Claim 5
Dependent Claim
42 words
A fluid-tight slide fastener according to claim 1, charaterized in that said tape is made of a woven fabric (21) including a warp thread thicker than the other threads of said woven fabric, said longitudinal thread providing said longitudinal ridge portion (28).
