The coronal blowout jet is a peculiar category among various jet phenomena,of which the sheared base arch, often carrying a small filament, experiences aminiature version of blowout eruption that produces large-scale coronal massejection (CME). In this paper, we report such a coronal blowout jet withhigh-resolution multi-wavelength and multi-angle observations taken from SolarDynamics Observatory, Solar Terrestrial Relations Observatory, and Big BearSolar Observatory. For the first time, we find that a simultaneous bubble-likeand a jet-like CMEs were dynamically related to the blowout jet that showedcool and hot components next to each other. Our observational results indicatethat: (1) the cool component was resulted from the eruption of the filamentcontained within the jet's base arch, and it further caused the bubble-likeCME; (2) the jet-like CME was associated with the hot component, which was theoutward moving heated plasmas generated by the reconnection of the base archand its ambient open field lines. On the other hand, bifurcation of the jet'scool component was also observed, which was resulted from the uncoupling of theerupting filament's two legs that were highly twisted at the very beginning.Based on these results, we propose a model to interpret the coronal blowoutjet, of which the external reconnection not only produces the jet-like CME butalso leads to the rising of the filament. Subsequently, internal reconnectionstarts underneath the rising filament and thereby causes the bubble-like CME.
