and a second member extending from the second portion, the second member having at least a portion extending substantially orthogonal to the second portion; wherein movement about the living hinge will cause the first member and the second member to engage each other with an interference fit to hold a relative position between the first portion of the planar member and the second portion of the planar member. ### Claim 4 (depends on 2) The refrigeration display case of claim 2, wherein the releasable holding device comprises: a first member extending from the first portion of the planar member, the first member having at least a portion that is substantially orthogonal to the first portion; and a second member extending from the second portion, the second member having at least a portion extending substantially orthogonal to the second portion; wherein movement about the living hinge will cause the first member and the second member to engage each other with one having a ball and one a socket. ### Claim 5 (depends on 1) The refrigeration display case of claim 1, wherein the coil cover further comprises a sealing member formed on the first end of the planar member for interfacing with the at least one fan plenum. ### Claim 6 (depends on 5) The refrigeration display case of claim 5, wherein the sealing member comprises a plurality of flexible barbs extending from a first surface of the planar member proximate the first end of the planar member. ### Claim 7 (depends on 1) The refrigeration display case of claim 1, wherein the attachment member comprises a J-hook formed on the second end. ### Claim 8 (depends on 1) The refrigeration display case of claim 1, wherein the attachment member comprises a screw. ### Claim 9 (depends on 1) The refrigeration display case of claim 1, wherein the planar member comprises a plastic material and further comprises a plurality of stiffening ribs. ### Claim 10 (depends on 1) The refrigeration display case of claim 1, wherein the living hinge extends along 80 to 100 percent of a length from the first end to the second end of the planar member. ### Claim 11 (depends on 1) The refrigeration display case of claim 1, wherein the living hinge extends along 80 to 95 percent of a length from the first end to the second end of the planar member. ### Claim 12 (depends on 1) The refrigeration display case of claim 1, wherein the living hinge is formed from the same material as the planar member. ### Claim 13 (depends on 12) The refrigeration display case of claim 12, wherein the living hinge is formed from the same material as the planar member and has a thickness that is less than half of thickness of the planar member. ### Claim 14 (depends on 1) The refrigeration display case of claim 1, wherein the living hinge is formed from a material that is different from a material from which the planar member is formed. ### Claim 15 (depends on 1) The refrigeration display case of claim 1, wherein the coil cover further comprises a releasable holding device for holding the first portion of the planar member in a position angled to the second portion of the planar member; wherein the coil cover further comprises a sealing member formed on the first end of the planar member for interfacing with the at least one fan plenum; wherein the sealing member comprises a plurality of deformable barbs extending from a first surface of the planar member proximate the first end of the planar member; wherein the attachment member comprises a J-hook formed on the second end; wherein the planar member comprises a plastic material and further comprises a plurality of stiffening ribs; and wherein the living hinge extends along 80 to 100 percent of a length from the first end to the second end of the planar member. ### Claim 16 A refrigeration display case for refrigerating and displaying perishable goods, the refrigeration display case comprising: a plurality of evaporator coils for cooling air; a display case frame forming a display area; a coil cover that covers a portion of the plurality of evaporator coils and coupled to the display case frame; and wherein the coil cover comprises: a planar member having a top side, a bottom side, a front end, a back end, a first side end, and a second side end, a living hinge formed in the planar member extending from the first side end to the second side end and defining a first portion of the planar member and a second portion of the planar member, and wherein the living hinge is configured to allow movement between the first portion of the planar member and the second portion of the planar member, and an attachment member for coupling the coil cover to the display case frame. ### Claim 17 (depends on 16) The refrigeration display case of claim 16, further comprising a sealing member coupled to the top side of the planar member proximate the front end. ### Claim 18 (depends on 16) The refrigeration display case of claim 16, further comprising a releasable holding device having a first releasable holding member formed on the first portion of the planar member and a second releasable holding member formed on the second portion of the planar member, and wherein the first releasably holding member and the second releasable holding member are configured to releasable couple to one another to hold the first portion of the planar member at an angle to the second portion of the planar member. ### Claim 19 (depends on 18) The refrigeration display case of claim 18, wherein the first releasable holding member and second releasable holding member comprise a ball and socket. ### Claim 20 (depends on 16) The refrigeration display case of claim 16, further comprising: a sealing member coupled to the top side of the planar member proximate the front end;
