Abstract
Abstract An improved hanger assembly is provided for use with bottles containing liquids, particularly glass vessels for holding liquids to be administered parenterally. The hanger includes a frangibly-activated hinge that biases the rotation of a hook or loop into a position to enable safe and expeditious hanging of the bottle. The assembly is a substantially rigid unitary construction made of material having a substantially uniform thickness, i.e., not having any elements protruding outside of the general profile of the bottle to be hung. The assembly maintains this profile until the frangibly-activated hinge is broken to allow rotation of the hook or loop into a position to permit hanging. Further, use of a frangibly-activated hinge permits the use of design and materials for the hanger assembly which reduce the risks of tearing the hanger and improve the bottle orientation when it is hung.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
147 words
A method for hanging an article, said article connected to a hanger assembly having a skirt with an upper rim and a tab substantially rigidly appending inwardly from said skirt in a plane substantially parallel to that which is defined by the rim of said skirt, said tab including (a) a suspension means for suspending the article, (b) a frangibly-activated hinge spaced between the skirt and the suspension means, and (c) means interposed between the hinge and skirt for resilient displacement of the suspension means along an axis generally parallel to that of the skirt whereby shock and stress on the hinge is adsorbed, the method comprising applying sufficient force to the suspension means in a direction generally perpendicular to the plane defined by the rim of the skirt to break a portion of the hinge and thereby allow rotation of the suspension means about the hinge.
