Abstract: Energy losses from market refrigerated display cases, which are normally open, can be dramatically reduced by use of an access shield according to the present invention. The access shield comprises a plurality of transparent and resilient panels, each panel being adjacent to at least one other and having an overlapping relationship with the adjacent panel. The panels may be mounted in a rigid frame and allow access therethrough by stretching and bending of one or more of the panels along the overlapped line. The plurality of panels may also be fitted to a spring-tensioned roller and stretched across the aperture of the refrigerated display case. In another embodiment, the plurality of panels may each be attached at an opposite end to a holder having a bow tie shaped protrusion which is urged into a receiving indentation in a fixture to temporarily lock the panel in a predetermined position and yet to permit free rotation within a sector to facilitate access. Other embodiments are also disclosed.
