A simple model of hadron which exhibits the quark confinement and the asymptotic freedom is described. The hadron is modelled as a sphere of radius equal to its Compton wavelength in which quarks occur surrounded by space with the uniformly distributed \it negative vacuum energy density characterized by λ. The acceleration stemming from this vacuum energy causes the quark confinement. However, in the center of hadron quarks behave as practically free particles. From the requirement that the Compton wavelength of a hadron should remain constant while the scale factor varies with time we estimate the strength of the vacuum energy density surrounding quarks. It follows that the inward pressure of this vacuum energy is large enough to keep quarks inside the hadron.
