Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
320 words
A fastener assembly comprising in combination: first and second interlockable resiliently flexible fastener strips each having a continuous sheet form longitudinally extending web portion and each having a resiliently flexible longitudinally extending locking portion; each of said fastener strips having said web and locking portions thereof integrally connected in substantially a common plane, and said web portion providing connecting means; each locking portion having a first two continuous shaped locking profile ribs extending therealong and projecting a first lateral direction; each locking portion having a second two shaped locking profile ribs extending continuously therealong projecting in a second opposite direction; each of said ribs projecting individually from its locking portions each of said first and second two shaped ribs of each locking portion having a continuous locking groove therebetween interlockingly receptive of the locking profile of sid ribs and either of said two ribs of either locking portion being adapted to interlock into either of the grooves of the other locking portion; said grooves being of the same size on both sides of said locking portions and said ribs being of the same size on both of said locking portions so that said fastener strips may be interlocked from either lateral direction; each web portion extending in a respective plane which is substantially parallel to the plane of the other web portion when the ribs and grooves are interlocked; each of said ribs being individually resiliently flexible and being arrow shaped with a central tip and barbs extending laterally at each side of the tip so that in the interlocked relation of the fastener strips two selected ribs of the first strip will be interlocked with two selected ribs of the second strip; and the distance between said barbs at each groove being less than the width of each rib between its barbs so that the ribs can snap into interengagement and the barbs will retain the locking portion interlocked.
Claim 2
Dependent Claim
320 words
A fastener assembly comprising in combination: first and second interlockable resiliently flexible fastener strips each having a continuous sheet form longitudinally extending web portion and each having a resiliently flexible longitudinally extending locking portion; each of said fastener strips having said web and locking portions thereof integrally connected in substantially a common plane, and said web portion providing connecting means; each locking portion having a first two continuous shaped locking profile ribs extending therealong and projecting a first lateral direction; each locking portion having a second two shaped locking profile ribs extending continuously therealong projecting in a second opposite direction; each of said ribs projecting individually from its locking portions each of said first and second two shaped ribs of each locking portion having a continuous locking groove therebetween interlockingly receptive of the locking profile of sid ribs and either of said two ribs of either locking portion being adapted to interlock into either of the grooves of the other locking portion; said grooves being of the same size on both sides of said locking portions and said ribs being of the same size on both of said locking portions so that said fastener strips may be interlocked from either lateral direction; each web portion extending in a respective plane which is substantially parallel to the plane of the other web portion when the ribs and grooves are interlocked; each of said ribs being individually resiliently flexible and being arrow shaped with a central tip and barbs extending laterally at each side of the tip so that in the interlocked relation of the fastener strips two selected ribs of the first strip will be interlocked with two selected ribs of the second strip; and the distance between said barbs at each groove being less than the width of each rib between its barbs so that the ribs can snap into interengagement and the barbs will retain the locking portion interlocked.
Claim 3
Dependent Claim
35 words
A fastener assembly constructed in accordance with claim 1: including plastic film sheets attached to each of the web portions and extending away from the locking portions to form a continuation of the web portions.
Claim 4
Dependent Claim
45 words
A fastener assembly constructed in accordance with claim 1: including a second web portion for each of the fastener strips on the opposite side of the locking portion and extending in substantially a common plane with the first mentioned web portion and the locking portion.
Claim 5
Dependent Claim
34 words
A fastener assembly constructed in accordance with claim 3: wherein said first and second web portions are continuous to form a tube with said locking portions being located in the wall of the tube.
