  • Patent number: 10413384
    Abstract: The invention relates to a container (1) for storing and discharging at least one component with at least one chamber (4, 4a, 4b), which is sealed on a first side by a plug (9), and with one applicator (5) attached on the first side. A flow connection between the at least one chamber (4, 4a, 4b) and the side of the applicator (5) facing away from the at least one chamber (4, 4a, 4b) is opened by a relative rotational movement of the applicator (5) to the container (1) and a subsequent axial relative movement of the plug (9) to the container (1) and the applicator (5), in particular due to pressure of the at least one component on the plug (9). Furthermore, the invention relates to a method for storing and discharging at least one component.
