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. Additionally, an improved closure device in combination with a bag structure is provided comprising a plastic strap having a single aperture at one end adapted to receive the opposite end of the strap when the strap is used for securing an open mouth bag in a closed position. Such a strap is advantageously detachably secured near the open mouth portion of the bag to assure user convenience for ready accessibility of the strap locking device when it is desired to secure the bag in a closed position.
A device for closure of flexible bag structures which comprises a flexible elongated strap having at least two longitudinally spaced-apart perforations, one end of said strap being elongatedly tapered such that said tapered end may be inserted into and pulled through one of said perforations spacedapart from another of said perforations said latter perforation being intermediate said tapered end portion (being inserted) and said perforation through which said end portion is inserted to form a noose, said elongatedly tapered strap end being further characterized by having outwardly projecting shoulders at opposite edges of said strap, approximately at the point where said flexible strap begins to taper, whereby when said noose is formed and said elongatedly tapered end is pulled through said perforation at said end portion of said strap, said intermediate perforation engages with the perforation through which said end portion is inserted to provide for said noose, a lock which is further reinforced by engagement of said shoulders with the engaged perforations.
