Abstract
Abstract A multi-closure strip of generally flat, rigid, plastic closures which are joined in an elongated strip by sets of transversely spaced webs in which the webs have enlarged central portions terminating in reduced transverse widths at the junctures of the closures with the webs. Preferably, the central portion is symmetrically or equidistantly located lengthwise between the closures and is of a circular configuration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
111 words
In a multi-closure strip wherein the closures each have a side-edge, bag-neck access opening joining a bag-neck confining aperture, said closures being joined together in such strip by webs spaced transverse to the length of the strip, the webs having a thickness in the length direction of the strip to space adjacent closures, and each said web having a transversely enlarged central portion relative to the lengthwise direction of the strip and transversely reduced points of fracture on each end of said central portion at the juncture of the closure and web whereby separation of the closures by breaking the points of fracture will leave a smooth edge at each closure.
Claim 2
Dependent Claim
111 words
In a multi-closure strip wherein the closures each have a side-edge, bag-neck access opening joining a bag-neck confining aperture, said closures being joined together in such strip by webs spaced transverse to the length of the strip, the webs having a thickness in the length direction of the strip to space adjacent closures, and each said web having a transversely enlarged central portion relative to the lengthwise direction of the strip and transversely reduced points of fracture on each end of said central portion at the juncture of the closure and web whereby separation of the closures by breaking the points of fracture will leave a smooth edge at each closure.
Claim 3
Dependent Claim
28 words
The closure strip of claim 1, said enlarged central portion being generally circular about a center equidistantly spaced between points of tangency with adjacent closures in the strip.
Claim 4
Dependent Claim
16 words
The closure of claim 1 wherein said central portion is symmetrically located lengthwise of the strip.
Claim 5
Dependent Claim
96 words
In a multi-closure strip, said closures being joined together in such strip by webs spaced transverse to the length of the strip, the webs having a thickness in the length direction of the strip to space adjacent closures, and each said web having a transversely enlarged central portion relative to the lengthwise direction of the strip and transversely reduced points of fracture on each end of said central portion at the juncture of the closure and web whereby separation of the closures by breaking the points of fracture will leave a smooth edge at each closure.
Claim 6
Dependent Claim
96 words
In a multi-closure strip, said closures being joined together in such strip by webs spaced transverse to the length of the strip, the webs having a thickness in the length direction of the strip to space adjacent closures, and each said web having a transversely enlarged central portion relative to the lengthwise direction of the strip and transversely reduced points of fracture on each end of said central portion at the juncture of the closure and web whereby separation of the closures by breaking the points of fracture will leave a smooth edge at each closure.
