In this article, we take the point of view that the bottomed (0+,1+) mesons Bs0 and Bs1 are the conventional bs meson and calculate the strong coupling constants g_Bs0BK and g_Bs1B*K with the light-cone QCD sum rules. The numerical values of strong coupling constants g_Bs1B*K and g_Bs0BK are very large and support the hadronic dressing mechanism. Just like the scalar mesons f0(980), a0(980), Ds0 and axial-vector meson Ds1, the (0+,1+) bottomed mesons Bs0 and Bs1 may have small bs kernels of the typical bs meson size. The strong couplings to the hadronic channels (or the virtual mesons loops) may result in smaller masses than the conventional bs mesons in the potential quark models and enrich the pure bs states with other components.
