Abstract: The mixing device for mixing a liquid with a dry material, particularly a bleaching agent, includes a mixing container (1) for the liquid having a top edge and a screw thread on which a threaded cap (5) can engage to close the mixing container and a receiving insert (7) located between the top edge of the mixing container (1) and the threaded cap (5). The receiving insert (7) includes an insert top member (8) and an insert bottom member (9). The insert bottom member (8) is provided with tablet receptacles (12) for tablets of the dry material and throughgoing openings (14) connecting each tablet receptacle (12) with the interior of the mixing container (1). The insert top member (9) is provided with comminuting pins (16) projecting into the tablet receptacles (12) of the insert bottom member (9) so that tablets in the tablet receptacles can be smashed and the broken pieces delivered to the interior of the mixing container when the threaded cap is screwed sufficiently tightly to the mixing container.

Abstract: An arrangement for mixing two components has a vessel, a cover element placed on the vessel and having an upper region provided with a recess having an edge, at least one cutting mandrel provided on the edge of the recess, and a releasable depot vessel inserted in the recess of the cover element and having a foil at a side of the vessel. The depot vessel has a lower inner diameter which is greater than a double distance between a central axis of the depot vessel and the cutting mandrel.

Abstract: An arrangement for mixing two components comprises a container having a first engaging formation, a closing element having a second engaging formations cooperating with the first engaging formation when the closing element is screwed onto the container, and a removable receptacle releasably connectable with the closure element and having a foil which faces an interior of the container when the closure element is screwed onto the container, and is removable in an assembled condition so as to release a content of the receptacle into the interior of the container.
