The locking band extends across the top panel and holds an underlying portion of the top panel in face-contacting relationship with the bottom panel. The tray is configured to transition from a first, substantially flat configuration into a second, erect configuration in which the top panel defines a concave surface configured to hold in place a rounded item. The tray is configured to be transitioned from the first configuration to the second configuration by sliding the top panel relative to the bottom panel. ## Claims ### Claim 1 A tray formed from a blank of sheet material, the tray comprising: a bottom panel forming a bottom wall of the tray; a top panel forming a top wall of the tray; first and second side panels forming first and second side walls of the tray and extending between said top and bottom panels on opposite sides thereof; a locking band connected to said bottom panel at opposite upper and lower edges thereof, said locking band extending across said top panel and holding an underlying portion of said top panel in face-contacting relationship with said bottom panel; wherein said tray is configured to transition from a first configuration in which said tray is substantially flat into a second or erect configuration in which said top panel defines a concave surface configured to hold in place a rounded item; wherein said tray is configured to be transitioned from said first configuration to said second configuration by sliding said top panel relative to said bottom panel. ### Claim 2 (depends on 1) The tray according to claim 1, wherein the locking band overlies a generally central portion of the top panel when the tray is in the second configuration. ### Claim 3 (depends on 1) The tray according to claim 1 wherein said top panel has a first width and said bottom panel has a second width, and wherein said first width is smaller than said second width. ### Claim 4 (depends on 1) The tray according to claim 1, wherein said locking band is formed from overlapping first and second locking arm flaps, wherein said first locking arm flap is hingedly connected to the upper edge of said bottom panel, and wherein said second locking arm flap is hingedly connected to the lower edge of said bottom panel. ### Claim 5 (depends on 1) The tray according to claim 1, wherein at least one finger cutout is formed in said top panel. ### Claim 6 (depends on 5) The tray according to claim 5, wherein said at least one finger cutout comprises a first finger cutout formed along a first side edge of said top panel and a second finger cutout formed along a second opposite side edge of said top panel. ### Claim 7 (depends on 1) The tray according to claim 1, wherein a plurality of strengthening creases are formed in the first and second side panels. ### Claim 8 (depends on 1) The tray according to claim 1, wherein the top panel comprises a top center panel hingedly connected to a first top side panel and a second top side panel. ### Claim 9 (depends on 8) The tray according to claim 8, wherein said locking band comprises first and second locking tabs configured to be received within respective first and second locking apertures formed in the top panel so as to resist collapsing of the tray when the tray is in the second configuration. ### Claim 10 A blank of sheet material for forming a tray, the blank comprising: a plurality of panels hingedly connected in series, the plurality of panels comprising a top panel configured to form a top wall in a set-up tray, a first side panel configured to form a first side wall in the set-up tray, a bottom panel configured to form a bottom wall in the set-up tray, and a second side panel configured to form a second side wall in the set-up tray; a first locking arm flap hingedly connected to the bottom panel along an upper edge thereof and a second locking arm flap hingedly connected to the bottom panel along a lower edge thereof; wherein the first and second locking arm flaps are configured to be secured together to form a locking band in the set-up tray, the locking band extending across said top panel and holding an underlying portion of said top panel in face-contacting relationship with said bottom panel; wherein the set-up tray is configured to transition from a first configuration in which said set-up tray is substantially flat, into a second or erect configuration in which said top wall defines a concave surface configured to hold in place a curved item; wherein said set-up tray is configured to be transitioned from said first configuration to said second configuration by sliding said top panel relative to said bottom panel. ### Claim 11 (depends on 10) The blank according to claim 10, wherein said plurality of panels comprises a glue flap panel configured to be secured in face-contacting relationship to the second side panel in the set-up tray. ### Claim 12 (depends on 10) The blank according to claim 10, wherein the locking band overlies a generally central portion of the top panel when the tray is in the second configuration. ### Claim 13 (depends on 10) The blank according to claim 10, wherein said top panel has a first width and said bottom panel has a second width, and wherein said first width is smaller than said second width. ### Claim 14 (depends on 10) The blank according to claim 10, wherein at least one finger cutout is formed in said top panel. ### Claim 15 (depends on 14) The blank according to claim 14, wherein said at least one finger cutout comprises a first finger cutout formed along a first side edge of said top panel and a second finger cutout formed along a second opposite side edge of said top panel. ### Claim 16 (depends on 10) The blank according to claim 10, wherein a plurality of strengthening creases are formed in the first and second side panels. ### Claim 17 (depends on 10) The blank according to claim 10, wherein the top panel comprises a top center panel hingedly connected to a first top side panel and a second top side panel. ### Claim 18 (depends on 8) The blank according to claim 8, wherein said locking band comprises first and second locking tabs configured to be received within respective first and second locking apertures formed in the top panel so as to resist collapsing of the set-up tray when the set-up tray is in the second configuration.
