AI Technical Summary

Benefits of technology

"The present invention is an improved bag closure that can securely enclose a flexible bag or object by using an elastomeric cord with a slidable lock. The slidable lock has biasing means that grip the cord and prevent it from slipping. The closure can be opened and closed repeatedly, and the elastomeric cord can hold its shape even when the lock is in use. The closure can be used for a variety of purposes such as securing bags, grasping objects, and joining other objects. The elastomeric cord is made of flexible films such as plastic or cloth, and can be molded or formed into a U-shape to hold its shape."

Problems solved by technology

The ubiquitous “wired paper twist tie” used for freezer bags, plastic bags, loafs of bread, etc., has a number of limitations, as do other approaches such as clamps, plastic clips, including those with a notch for receiving the flexible material of a bad, and related devices.
Twist ties and other closures may easy to lose, for example, and sometimes require high levels of dexterity to use or force.
Existing closures also may not provide tight seals.
Further, currently known methods tend to be unattractive and in some cases are not useful for many repeat uses.

Embodiment Construction

[0021]FIGS. 1A and 1B show an embodiment of the pull tie 20 of the present invention. A deformable, resilient elastomeric cord 22 is provided substantially in a U-shape defined by a bend 40 from which descends a first leg 30 and a second leg 32 of the elastomeric cord 22. The legs 30, 32 of the elastomeric cord 22 are engaged (and, in some embodiments, held in place) with a slidable lock 24 comprising a body 26 through which the elastomeric cord 22 passes and a depressible plunger 28, here visible as an external button that can be depressed. Not visible from this perspective are at least one internal bore within the depressible plunger 28 that receives the legs 30, 32 of the elastomeric cord 22. Also not shown is bias means such as an internal spring between the lower surface of the slidable lock body 26 and the depressible plunger 28 that urges the depressible plunger 24 upward to grip the elastomeric cord 22 and prevent relative motion of the slidable lock 24 and the elastomeric c...

Abstract

A pull tie is described comprising an elastomeric cord and a slidable stop. The pull tie can be suitable for releasable, multi-use closures for flexible bags and containers.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Patent Appl. Ser. No. 61 / 093,659, “Releasable Pull Tie,” filed Sep. 2, 2008, which is hereby incorporated by reference in its entirety for all purposes.BACKGROUND[0002]1. Field of the Invention[0003]This invention pertains to releasable, multi-use closures for flexible bags and containers. In particular, this invention pertains to releasable pull ties for closing flexible bags.[0004]2. Description of Related Art[0005]Plastic bags used for numerous items of food require reusable closure means to allow the food to repeatedly be opened and closed. The ubiquitous “wired paper twist tie” used for freezer bags, plastic bags, loafs of bread, etc., has a number of limitations, as do other approaches such as clamps, plastic clips, including those with a notch for receiving the flexible material of a bad, and related devices. Twist ties and other closures may easy to lose, for example, and sometimes require ...
