Abstract

Abstract A U-shaped clip intended to be deformed to enclose and close the mouth of a flexible tube or bag, comprising a pair of limbs of substantially constant cross-section and a web joined to the limbs, respectively at a pair of transition points, the cross-sections of the web and transition points differing from and having a higher section modulus than the cross-section of the limbs. Advantageously the limbs are round in cross-section and the web at the middle is rectangular with rounded corners, the web changing in cross-section gradually from the middle to the transition points. Indentations may be provided on the outside of the limbs near their ends to facilitate buckling of the limbs toward one another when the clip is worked upon by a closing tool. The clips are assembled one behind the other with their limbs forming two parallel lines, constituting a magazine for supply to the closing tool.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 78 words
A U-shaped wire clip intended to be permanently deformed to enclose and close the mouth of a flexible tube or bag, comprising a pair of limbs of substantially constant cross-section and a web joined to the limbs at a pair of transition points, the cross-sections of the web and transition points differing from and having a higher section modulus than the cross-section of the limbs, the cross-sectional areas of the web, transition points and limbs being substantially constant.
Claim 2
Dependent Claim 78 words
A U-shaped wire clip intended to be permanently deformed to enclose and close the mouth of a flexible tube or bag, comprising a pair of limbs of substantially constant cross-section and a web joined to the limbs at a pair of transition points, the cross-sections of the web and transition points differing from and having a higher section modulus than the cross-section of the limbs, the cross-sectional areas of the web, transition points and limbs being substantially constant.
Claim 3
Dependent Claim 29 words
A clip according to claim 1, wherein the cross-section of the limbs is approximately circular and that of the web and transition points is approximately rectangular with rounded corners.
Claim 4
Dependent Claim 26 words
A clip according to claim 1, wherein the cross-section of the limbs is approximately circular and that of the web and transition points is approximately rhombic.
Claim 5
Dependent Claim 27 words
A clip according to claim 1, wherein the cross-section of the limbs is approximately circular and that of the web and transition points is approximately dumbbell shaped.
Claim 6
Dependent Claim 42 words
A clip according to claim 1, wherein the cross-section of the limbs is approximately circular and the cross-section of the web is most out-of-round midway between limbs, the cross-section of the web changing gradually from the midway position to the transition points.
Claim 7
Dependent Claim 46 words
A clip according to claim 1, wherein the limbs are provided with indentations toward their ends which indentations are on the outsides of the limbs facing away from one another, thereby facilitating buckling of the limbs toward one another when worked upon by a closing tool.
Claim 8
Dependent Claim 57 words
A clip according to claim 6, wherein the cross-section of the limbs is approximately circular, and the cross-section of the web midway between the limbs is approximately rectangular with rounded corners, the cross-section of the web is most out-of-round midway between limbs, the cross-section of the web changing gradually from the midway position to the transition points.
Claim 9
Dependent Claim 20 words
An assembly of clips according to claim 1 arranged one behind the other with their limbs forming two parallel lines.
