Abstract
Abstract In a U-shaped clip made from strip material and intended to close bags and flexible tubes, said clip comprising a web connecting two limbs having outwardly angled end lugs, the improvement which comprises forming the surface of the clip which is to engage a bag so as to provide elevated and depressed zones to grasp the bag more securely. The elevated and depressed portions can be established by forming longitudinal beads on the inside of the clip along the web and limbs or by forming longitudinal grooves on such inside.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
In a U-shaped clip made from substantially flat strip material and intended to close bags and flexible tubes, said clip comprising a web connecting two limbs having outwardly angled end lugs, the improvement which comprises providing on the surface of the clip which is to engage a bag a pair of spaced parallel beads extending longitudinally along the outer edges of the web and limbs, the material forming said beads being displaced inwardly from the outer longitudinal edges of the strip, and also providing in the surface of the clip which is to engage a bag a plurality of longitudinal parallel grooves in each limb and in the web, the grooves being discontinuous in that they are absent at the joinders between the limbs and web, the clip face opposite the grooved face being substantially flat, whereby such beads and grooves serve to grasp the bag more securely.
Claim 2
Dependent Claim
148 words
In a U-shaped clip made from substantially flat strip material and intended to close bags and flexible tubes, said clip comprising a web connecting two limbs having outwardly angled end lugs, the improvement which comprises providing on the surface of the clip which is to engage a bag a pair of spaced parallel beads extending longitudinally along the outer edges of the web and limbs, the material forming said beads being displaced inwardly from the outer longitudinal edges of the strip, and also providing in the surface of the clip which is to engage a bag a plurality of longitudinal parallel grooves in each limb and in the web, the grooves being discontinuous in that they are absent at the joinders between the limbs and web, the clip face opposite the grooved face being substantially flat, whereby such beads and grooves serve to grasp the bag more securely.
Claim 3
Dependent Claim
19 words
A clip according to claim 1, wherein the beads extend beyond the joinder between the limbs and connecting lugs.
Claim 4
Dependent Claim
14 words
A clip according to claim 1, wherein each connecting lug is dome-like in configuration.
Claim 5
Dependent Claim
16 words
A strip of clips according to claim 1, successively joined to one another at their lugs.
Claim 6
Dependent Claim
76 words
A clip according to claim 1, wherein the beads extend beyond the joinder between the limbs and connecting lugs and each connecting lug is dome-like in configuration, the clip being successively joined to like clips at their lugs to form an elongated strip from about 3 to 10 mm wide, each clip being of a length to form an enclosure of about 10 to 25 mm measured in the plane of the top of the strip.
Claim 7
Dependent Claim
86 words
In a U-shaped clip made from substantially flat strip material and intended to close bags and flexible tubes, said clip comprising a web connecting two limbs having outwardly angled end lugs, the improvement which comprises forming the surface of the clip which is to engage a bag so as to provide longitudinal parallel grooves in each limb and in the web with no grooves at the joinders between the limbs and web, the surface of the clip which is opposite the grooved face being substantially flat.
