Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 229 words
A pair of carrying handles of flexible plastics material for a carrier bag, each handle comprising a mounting strip of which a first longitudinal marginal portion is attachable to a respective wall of the bag along the mouth thereof and a second longitudinal marginal portion is of substantially U section and disposed beyond the mouth when said first portion is so attached, a hand grip portion defining a hand hole, and means for interengaging said handles with said first portions in face-to-face contact and with the openings of the U sections confronting one another, wherein at least along parts of the lengths of the mounting strips the respective limbs of the U sections furthest from said first marginal portions extend beyond the contacting faces of said first marginal portions so that one of these limbs overlies the other limb when the handles are interengaged, the said one limb terminates in a hook-like member received in a recess of the U section possessing the other limb when the handles are interengaged, the U section possessing said one limb is provided with a flange parallel to said one limb and spaced therefrom by a distance corresponding to the thickness of said other limb, and wherein the said other limb and the said flange have a length such that they abut the webs of the U sections when the handles are interengaged.
Claim 2
Dependent Claim 229 words
A pair of carrying handles of flexible plastics material for a carrier bag, each handle comprising a mounting strip of which a first longitudinal marginal portion is attachable to a respective wall of the bag along the mouth thereof and a second longitudinal marginal portion is of substantially U section and disposed beyond the mouth when said first portion is so attached, a hand grip portion defining a hand hole, and means for interengaging said handles with said first portions in face-to-face contact and with the openings of the U sections confronting one another, wherein at least along parts of the lengths of the mounting strips the respective limbs of the U sections furthest from said first marginal portions extend beyond the contacting faces of said first marginal portions so that one of these limbs overlies the other limb when the handles are interengaged, the said one limb terminates in a hook-like member received in a recess of the U section possessing the other limb when the handles are interengaged, the U section possessing said one limb is provided with a flange parallel to said one limb and spaced therefrom by a distance corresponding to the thickness of said other limb, and wherein the said other limb and the said flange have a length such that they abut the webs of the U sections when the handles are interengaged.
