Abstract

Plastic fastener and plastic fastener assembly. The plastic fastener may include a flexible filament having a first end and a second end. A cross-bar may be disposed at the first end of the flexible filament, and a paddle may be disposed at the second end of the flexible filament. The paddle may have an upper portion and a lower portion. The upper portion may extend downwardly from a top surface of the paddle and may have a comparatively lesser thickness, and the lower portion may extend upwardly from a bottom surface of the paddle and may have a comparatively greater thickness. The lower portion may include a projection extending outwardly from a front surface of the paddle. The projection may have a flat front surface or may have a curved front surface. A plurality of the plastic fasteners may be formed as continuously connected fastener stock.

PLASTIC FASTENER AND PLASTIC FASTENER ASSEMBLY

Cross Reference to Related Application(s)

[0001]               The present application claims priority from U.S Provisional Application No. 61/151046 filed April 22, 2015, which is incorporated by herein by reference in their entirety.

Field of the Invention

[0002]               The present invention relates generally to plastic fasteners of the type typically used in the packaging and/or sale of articles of commerce and relates more particularly to a novel such plastic fastener and to a fastener assembly including the same. 

Background of the Invention

[0003]               Plastic fasteners of the type used, for example, to attach merchandise tags to articles of commerce or to secure articles of commerce to packaging are well-known and widely used in the retail industry.  One common such fastener is a unitary plastic member comprising a flexible filament, a cross-bar (also commonly referred to as a “T-bar”) at a first end of the flexible filament, and a paddle or other enlargement at a second end of the flexible filament.  When used, for example, to secure a merchandise tag to an article of commerce, the cross-bar may be inserted through the merchandise tag and then through the article of commerce, with the paddle or other enlargement not being inserted through the merchandise tag or article of commerce and being appropriately sized and shaped to keep the tag from being pulled off the second end of the flexible filament.  In an analogous fashion, when used, for example, to secure an article of commerce to packaging material, the cross-bar may be inserted through the packaging material, with the paddle or other enlargement not being inserted through the packaging material.

[0004]               Plastic fasteners of the type described above are typically mass-produced in either one of two different forms known as fastener stock.  A first type of fastener stock is a clip-type assembly, said assembly comprising a plurality of fasteners, each such fastener comprising a flexible filament having a cross-bar at one end thereof and a paddle or other enlargement at the opposite end thereof.  The fasteners are arranged in a stacked orientation, with the respective cross-bars parallel to one another and the respective paddles parallel to one another, each of the cross-bars being joined to a common, orthogonally-disposed runner bar by a severable connector.  Adjacent paddles also may be interconnected by severable connectors extending between the front face of one paddle and the rear face of its adjacent paddle.

[0005]               The aforementioned fastener assembly is typically made through the process of injection molding.  Several commercial embodiments of the above-described fastener assembly have been sold by the present assignee, Avery Dennison Corporation, as DENNISON® SWIFTACH® fastener clips.

[0006]               A second type of fastener stock is shown in U.S. Patent No. 4,955,475, which issued on September 11, 1990, in the names o...
