Problems solved by technology

Because the cord or chain component does not facilitate pushing the barb through the opening, the cord or chain component can make initially installing the tether into the container opening particularly difficult, especially when the opening has an extended length
Rope or chain type connectors also preclude effective bulk packaging due to the ease with which rope or chain connectors can become complex

Embodiment Construction

[0023] Before any individual embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or shown in the drawings. The application is capable of other independent embodiments and of being practiced or carried out in various ways.

[0024] Figure 1-2 5-10 show the tether 20 in a first configuration. Tether 20 includes a connector portion 24 defining an axis 26 and a latch portion 27 including a plurality of barbs 28 . The plurality of barbs 28 (eg, two barbs) are diametrically opposed to each other about the axis 26 in the configuration shown, although other arrangements are optional. The connector part 24 is shape stable, ie it retains its original shape despite being flexible, and is constructed of a non-slack material (eg molded HDPE), as opposed to a slack chain or cord.

Abstract

A closure assembly for closing an opening in a container includes a closure member including an engagement structure configured to engage the opening. A tether includes a connector portion, a first end, and a second end. The first end is coupled to the closure member and the second end is opposite the first end. A plurality of barbs are positioned at the second end of the tether, each of the plurality of barbs has a rigid construction. The plurality of barbs define a maximum splayed dimension to retain the closure member with respect to the opening. A movable joint couples each of the plurality of barbs to the second end. Each of the plurality of barbs is foldable about the respective movable joint so that the plurality of barbs define a dimension substantially smaller than the maximum splayed dimension to allow insertion through the opening.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / 552,802, filed October 28, 2011, the entire contents of which are incorporated herein by reference. Background technique [0003] The present invention relates to tethers for closures such as caps or other closures (eg fuel caps) which close an opening in a container. [0004] A tether is typically attached to a portion of the lid and coupled to a portion of the container to keep the lid connected to the container even when the lid is removed from engagement with the container opening. An internal type tether is attached to the inside of the lid and holds the lid to the container by extending into and engaging the interior of the container. [0005] Known internal types of tethers may include flexible barbs that can be easily assembled into a container opening, but suffer from very limited resistance to being pulled back out of the opening. Some i...
