Put a pendulum in your box attached to the lid and set it swinging before you drop the box on the conveyor belt: The dynamic (kinetic) friction will then implicitly depend on time: f_k(t) = mu_k N(t) . I am not aware of any dry friction models that are explicitly time dependent; that would be a very strange model of dry friction. I can't even take a wild stab at what could cause that.
