A container formed from at least one blank of sheet material includes a tray, a cover configured to close the tray, and a locking device. The tray includes a tray front panel. The cover includes a cover front panel that extends downwardly from a front edge of a cover top panel. The cover front panel is configured to be positioned in an at-least partially overlapping arrangement with the tray front panel when the cover is closed. The locking device includes a locking tab hingedly attached to the cover top panel and struck in part from the cover top panel and in part from the cover front panel. The locking device also includes a locking recess struck from an upper edge of the tray front panel. The locking device is configured such that the locking tab can be pressed down into the locking recess to selectively secure the cover to the tray in a closed and locked configuration.
