Abstract: A safety device for at least one container, in particular a blow-molded plastic container, preferably in ampoule form, has a supply part (5) for accommodating a medium which can be dispensed via a container opening (9). The container opening (9) can be closed by a first safety part (11) which counteracts opening forces with a predefinable resistance. The predefinable resistance can be overcome for the release of the container opening (9) with the aid of a second safety part (15) which interacts with the first safety part (11).

Abstract: A container, in particular a plastic ampule produced using a blow-molding process and filled and closed in the mold has a neck part (12) adjoining a container body (10) and threadly receiving a first cap part (14). A second cap part (16) extends at least partly between the first cap part (14) and the neck part (12) and is provided with an opening device (20). The opening device has at least one opening (22) for opening the container body (10), and can be closed by the first cap part (14). The first cap part (14) carries the second cap part (16) by the screwing-on process of the first cap part in such a way that the opening device (20) causes the container body (10) to be opened. A closure part (closure pin 26) of the first cap part (14) unblocks the opening (22) in the opening device (20) after the first cap part is unscrewed, with the second cap part (16) remaining on the neck part (12).

Abstract: A tank handle or cap is designed for the convenience of the consumer. One aspect of the invention cap allows the end user to determine at a glace and from a distance if the tank is full or empty based on color distinction and/or word imprints on different sides (halves) of the invention cap. The cap is removably securable to the tank in different orientations to effectively expose the telling side of the invention cap. This allows the user the ability not to have to go over to the tank and lift the tank to gauge if the tank is full or not. This will reduce the risk of possible back injury. Other design features include an easy-to-use grip and open and close directional indicators to allow clear and concise understanding and operation of tank valves.
