A plastic dispensing fitment and a plastic screw-on cap are connected in nested relation by an ultrasonic weld. When the cap is initially screwed onto the neck of a jar, the fitment is forced over the neck with a snap fit. When the cap is first unscrewed, the weld breaks to separate the cap from the fitment and enable removal of the cap from the jar while leaving the fitment attached to the jar.
