A recyclable composite container is provided. The recyclable composite container comprises a cardboard hollow body having an open end defining an opening, the body being formed by a sidewall having inner and outer surfaces, the sidewall being provided with an aperture at a distance from the open end. The recyclable composite container also comprises a framing element removably connectable to the open end having a collar sized and shaped for snugly fitting over said open end; and a resilient arm extending from the collar, the arm extending along the inner surface of the sidewall and having a projection sized and shaped to be removably fitted in the aperture of the sidewall of the hollow body. This construction allows connection of the framing element to the cardboard hollow body by fitting the projection of the resilient arm in the aperture of the hollow body, and disconnection of the framing element from the cardboard hollow body by pressing the projection to disengage the projection from the aperture and by pulling the framing element away from the cardboard hollow body.
