A system for storing cylindrical containers includes multiple container guides positioned parallel to each other. The barrier layer has a moisture vapor transfer rate of less than 10\u22122 gm2 per day and consists of a multilayer of at least two thin hydrogenated silicon nitride layers having alternately lower and higher densities. When none of the display unit of the image display apparatuses displays an image signal, the termination is performed using one of the termination unit of the display apparatuses. In one embodiment, the attachment pathway extends distally along a pair of substantially parallel longitudinal attachment struts to create an extended leaflet contact area, then angles circumferentially and distally from the former along distal attachment struts to define the bottom edge of the leaflets.
