I am not 100% sure however, I believe this item was used for fries or burgers from a takeway in Butlins. I could be wrong and if I am, please let me know. Based on the logo, I would suggest its from the late 90's of the Butlin's Holiday Worlds era.
This is the item you used to have that lovely pop corn, sweet is the best ;) The blue background is the rear of the other side of the box.
