  • Publication number: 20210362108
    Abstract: The disclosure relates to a specifically static mixer for mixing two components, with a housing, in which a mixing element is accommodated, and an input part with a first intake and a diametrically opposite second intake, wherein, within the input part, a first channel is formed between the first intake and the mixing chamber and a second channel is formed between the second intake and the mixing chamber. The first channel extends radially inward from the first intake and opens into a central opening in the cover. The second channel has two partial channels as storage chambers not leading into the mixing chamber, and two intake sections located radially within the storage chambers and leading into the mixing chamber. The intake sections branch off the respective storage chambers, extend inward in the opposite direction to the first channel and open into the central opening in the cover.

  • Publication number: 20210154697
    Abstract: The present disclosure relates to an application system comprising a cartridge having at least one container with a respective outlet, and a closure element that can sealingly close the outlet of the at least one container when the cartridge is in the delivery state. When in the storage state, the cartridge sealingly closes the closure element. When the cartridge is in the state of use, the closure element can be removed therefrom and an accessory can be connected to the outlet of the at least one container. According to the invention, the cartridge or the closure element comprises, in the delivery state, a connecting element which cannot be removed without being damaged, and the cartridge or the closure element, in the storage state, is connected via a connecting element that cannot be removed without being damaged, to a closure element or the cartridge.

  • 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.
