ABSTRACT:
A closure mechanism for a tubular member, open-ended container or glove. A channel member coupled to the portion to be closed forms a channel of an opened length corresponding to a distance around the portion to be closed. The channel has a cross-sectional area and terminates with one or two closely spaced openings having an opening cross-sectional area. A stretchable cord is present within the channel and extends outward beyond at least one of the openings. The stretchable cord has an unstretched cross-sectional area and a stretched cross-sectional area. The unstretched cross-sectional area is larger than the stretched cross-sectional area and the opening cross-sectional area. By pulling on the portion of the stretchable cord extending out of the opening or openings, the stretchable cord takes on the stretched cross-sectional area at least proximate the opening or openings. As a result, the stretchable cord freely slides in the channel and when the stretchable cord is then released, the stretchable cord returns to the unstretched cross-sectional area proximate the opening or openings. As a result, the stretchable cord is locked in the opening or openings and the channel is shortened to a closed length less than the opened length. This secures the tubular portion surrounded by the closure mechanism in a closed position. A release member is utilized to lengthen the channel from its closed length to an opened length and may be operated with only one hand.
