Abstract
A bag holder of the type wherein a bag mouth is to be received and supported by a closed-figure frame of variable shape, the frame being made up of two elements, one being adapted to be attached at one side to a support and the other at an opposite side having handle means for the application of traction to the frame to bring it to a bag-opening configuration in which the elements are oppositely bowed so that their middle portions are spaced apart, the two elements lying face to face in a bag-closing configuration and being articulated together at their ends, and is characterized by the elements being biased to a bowed bag-closing configuration in which both are bowed in one direction. The biasing will be such that the element adapted to be attached to a support is concave (relative to the support) in the bag-closing configuration, traction on the handle means to bring the frame to the bag-opening configuration bring the said element through a straight to a convex configuration, the other element being concave (relative to the support) at all times.
