Abstract
ABSTRACT OF THE DISCLOSURE
A tie strip is formed of a flexible resilient material in strip form, with regularly longitudinally spaced openings formed in the strip and a pair of oppositely directed pawl acting tongues protecting from opposite end edges of each opening toward each other. The strip, in application, is folded at its end about its medial axis and inserted in a selected opening and it is mov-able through the opening in only one direction when inclined to the strip at the engaging opening in such direction and is mov-able in the opposite direction upon reversal of the inclination, the opposite tongues functioning as opposing pawls.

Description
1ai~9479 The present invention relates generally to improvements in fastening devices and it relates generally to an improved tie strip for application to bags or other containers for maintaining the closure thereo~, to bunches of articles or to other uses.
It is a common practice in releasably securing bags in a closed condition to gather the border of the bag proximate its open end into a closed nec~ and applying a tie strip or other fas-tener or tie to the closed neckO This procedure is followed in a wide variety o~ applications such as to paper bags, plastic bags, net bags and the like which are used for fruits, vegetables and other ~oodstuffs, trash, garbage and the like. However, the fastening devices heretofore employed possess numerous drawbacks and disadvantages. They are unreliable, often difficult and in-convenient to apply or remove, relatively expensive~ and of little versatility and adaptability and otherwise leave much to be de-sired.
It is a principal object of the present invention to provide an improved ~astening device.
Another ob~ect of the present invention is to provide an improved tie or binding device.
; Still another ob~ect of the present invention is to provide an improved reusable tie strip having smooth side edges which is highly useful in releasably locking a bag or similar receptacle whlch is closed by gathering the nec~ thereof/ in binding a stack of articles or a container~
A further ob~ect of the present invention is to provide a device of the above nature which is characterized by its relia-bilityJ simpllcity, low cost, ruggedness, attractive appearance, ease and convenience of use and manufacture and great versatility 3 and adaptability.
~)399~9 1 The above and other objects o~ the present invention will become apparent lrom a reading o~ the ~ollowing description taken in conJunction with the accompanying drawing which illus-trates a pre~erred embodiment thereof.
In a sense the present invention contemplates the provi-sions of an improved tie strip comprising an elongated, pliable resilient strip ~lexible abou~ its longitudinal spaced openings formed therein along the medial axis and a flexible resilient tongue registering with each of the openings and pro~ecting longi-~udinally from an end edge o~ the respective opening and being integrally formed with the strip.
In its preferred construction the side borders or edges of the strip are continuous and thicker than its medial portion, Advantageously, the openings are o~ rectangular shape and are regularly, longitudinally spaced and a pair o~ tongues register with each opening and are of generally triangular shape with their bases coinciding with the opening end edges and their apices di-rected toward each other and ~ ightly longitudinally spaced. The strip is advanta~eously formed o~ a thermoplastic organic poly-meric resin.
The improved tie strip is easy and convenient to apply and kighten and to loosen and remove, and in its tightened condi-tion it is highly secure and is not likely to be accidentally ; released. The tie strip is inexpensive, of attractive appearance and of great versatility and adaptability and can be used to decoratively tie packages.

~ e~erring now to the drawings which illustrate a pre-ferred embodiment of the present invention, the re~erence numeral10 generally designates the tie strip stock from which the indivi-dual tie strips 11 are cut to the desired lengths depending on their ultimate applications. The strip stock is produced by any suitable method such as by continuous extrusion and cutting and is advantageously formed of a thermoplastic synthetic organic polymetic resin such as a polyolefin, for example, polyethylene or polypropylene, polyvinyl chloride or the like. Other resilient materials can be used, including metals.
~s shown, the longitudinal side borders or edges 12 of the stock 10 are smooth, continuous and thicker than the medial section of web 13, which constitutes a major portion of the strip~
The strip 11 including the web 13 is resilient and flexible and is resiliently ~oldable about its longitudinal medial axis. The width of the stock or strip as well as the length of the cut strip 11 may be as desired, depending on its end use, for example, it may have a width of 3/8 inch and a length of about 5 inches.
~ edially formed in the web 13 are regularly longitudi-nally spaced openings l~ of r~ugh~ transversely extending butter-fly configuration. More specifically each opening 1l~ may be con-~sidered to be o~ rectangular or square con~iguration with longi-tudinal side edges 16 and transverse end edges 15. Pro~ecting in-wardly from each of the opening end edges 15 is a pawl defining generally triangular tongue 17 o~ equilateral configuration. The tongues 17 are integrally formed with the web 13 and their bases are substantially coe~tensive and coinci.de with the opening end edges~ and their apices 18 are rnunded and medlally located. The :3~039~79 1 apices 18 of the pair of tongues 17 registering with each opening are longitudinally spaced by a necked space 19. The tongues 17 are resillent and are normally coplaner with the web 13.
The stock lG is cut into khe individual tie strips 11 of the desired length along cut lines 20. If desired, tie strips 11 can converge to form a pointed leading edge.
Considering now the operation o~ the improved tie strip 11~ in application, the strip 11 is wrapped around khe article to be tied, for example, the necked portion o~ a closed bag, and the leader 21 is bent downwardly about its longitudinal medial axis and inserted into an opening 13 proxima~e the article being tied to form a closed loop 23. The loop 23 is tightened by pulling the leader 21 and the opposite end 22 in opposing directions. In the above relative orientation, the advance of the leading portion of the strip 11 through a~ opening 14 is permitted, since with the advance of the strip through the opening, the strip is longi-tudinally folded by the contracting opening 14 and the trailing tongues 17 in the successive openings 14 of the advancing portion of the strip 11 se~uentially bend the trailing tongue 17 in the threaded opening 14 to allow the passage o~ the strip 11 khere-: 20 through as best seen in Figure 4.
; ~oweverJ retraction or reverse movement o~ the leader portion through the opening is prevented, since upon such reverse movement, a leading tongue 17 in the leader portion moves into engagement with the top or outer face o~ the trailing tongue 17 in the threaded opening and bends outwardly to overlap the lattertongue and effect an interlocking relationship. If it is des~red to loosen or open the loop 23, the inclination of the pierced -; portion of the strip 11 is reversed and is pulled in the direction of arrow B, as shown in Figure 3~ to open the loop 23, The rela-tionship of the tongues 17 in the reverse movement of the leader portion when the opposite re~ative incl-lnation is effected is ~1~39~79 1 similar to the relationship of khe tongues with the advance move-ment of the leader portion at the initial tightening inclLnation in the direction of arrow A.
While there has been described and illustratçd a pre-ferred embodiment of the present invention, it is apparent that numerous alterations, omissions and additions may be made with-out departing ~rom the spirit thereof.
While the:.preferred embodiment -Lllustrated strip 11 having thicker side edges, the tape can be flat or uniform in thickness, Also, for rough usage~ a reinforcing wire can be added along the side edges in a manner well known to the trade.
Also, the pawl tongues have been illustrated as being generally triangular; they may be semi-circular.
