• closures are known as so-called sports caps, which must be unscrewed for opening and removal of container contents only partially, so can remain on the neck of the container or the bottle, since such Sportscap has a removal opening, which released with only partial unscrewing and closes again when screwed on again.
• sportscaps enable athletes, especially cyclists, to drink while exercising without having to use both hands and without being in danger of losing the closure.
• these known sportscaps can not be used in sealed containers or bottles by means of a sealing film, since they can not provide access to the container contents.
• the object underlying the invention is seen to provide a closure of the type mentioned, which is designed such that it is also suitable to fulfill the functions of a sportscaps, even with sealed with a sealing film containers or bottles.
• the sealing connection of the cap with the neck of the container can be done in various ways, for. B. by welding or by gluing, etc.

• the closure for removing at least a portion of the container contents is not removed as a whole from the neck and not again laboriously sealingly placed in order to reclosure of the container. Rather, a loosening or partial screwing of the screw cap or second screw cap is sufficient to allow pouring container contents or drinking.
• This is of particular advantage in food or beverage bottles during the Sporting exercise, z. As when cycling, but it is understood that the invention is not limited to containers for drinks or food.
