<p>A closure mechanism (50) for a tubular member, open-ended container or glove comprises a channel member (51,52) coupled to the portion to be closed and a stretchable cord (54) extending through the channel (52) and outward beyond at least one of the channel openings. The stretchable cord has an unstretched cross-sectional area and a stretched cross-sectional area. By pulling on the portion of the stretchable cord (54) extending out of the opening or openings, the cord takes on the stretched cross-sectional area at least in the region of the opening or openings (58); as a result, the stretchable cord freely slides in the channel. When the stretchable cord is released it returns to the unstretched cross-sectional in the region of the opening or openings (58) and as a result, the cord is locked in the opening or openings and the channel is shortened to a closed length less than the opened length. A release member (59) is utilized to lengthen the channel from its closed length to an opened length and may be operated with only one hand.</p> |
