Abstract
Abstract A device for easily, quickly, and securely closing flexible bag structures comprising an elongated strap made of resilient material having at least two longitudinally spaced apart perforations. The strap has an end portion of configuration adapted for insertion into and pulling through a perforation in said strap spaced apart from another perforation intermediate said end portion and the perforation through which the end portion is inserted to form a noose. In use, such as for closing the gathered mouth of a bag, a positive lock is provided upon further pulling of said end portion until the intermediate perforation interlocks with the perforation through which the end portion is inserted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
A device for closure of flexible bag structures which comprises a flexible elongated strap having at least two longitudinally spaced-apart perforations, both end portions of said strap being elongatedly tapered such that either end may be inserted into and pulled through one of said perforations spaced apart from another of said perforations intermediate said end portion being inserted and said perforation through which said end portion is inserted to form a noose, said strap being adapted to securely close the open end of a flexible bag structure by gathering the bag structure opening, surrounding said gathered opening with said strap, passing an end portion of said strap, adapted for insertion into and through a perforation spaced apart from a perforation intermediate said end portion and said perforation through which said end portion is inserted, to form a noose, and pulling said end portion until said intermediate perforation engages with the perforation through which said end portion is inserted to provide a positive lock for said noose.
Claim 2
Independent Claim
166 words
A device for closure of flexible bag structures which comprises a flexible elongated strap having at least two longitudinally spaced-apart perforations, both end portions of said strap being elongatedly tapered such that either end may be inserted into and pulled through one of said perforations spaced apart from another of said perforations intermediate said end portion being inserted and said perforation through which said end portion is inserted to form a noose, said strap being adapted to securely close the open end of a flexible bag structure by gathering the bag structure opening, surrounding said gathered opening with said strap, passing an end portion of said strap, adapted for insertion into and through a perforation spaced apart from a perforation intermediate said end portion and said perforation through which said end portion is inserted, to form a noose, and pulling said end portion until said intermediate perforation engages with the perforation through which said end portion is inserted to provide a positive lock for said noose.
Claim 3
Dependent Claim
37 words
