Abstract
Abstract This invention is a combined closure cap and pour-out fitment of the type used to seal glass or plastic or similar containers and particularly containers containing dispensible products such as salad dressings. The combination contains a pour-out fitment which is applied to the container with the closure and which remains on the container after the sealing closure is removed for limiting the flow of the dressing or other products. The dispensing fitment is a separately molded disc-like structure with a center aperture and is adapted for being snapped into the closure prior to the application of the closure to a container. The fitment and closure combination seal the container without any additional sealing liner.
