Abstract: The agitator for hermetic mixing of active agent with carrier- and auxiliary materials, comprises a hermetic, detachable anchoring mechanism (15) for reversible opening and closing and for the hermetic transfer of a fluid particulate material containing a first and a second component of a mechanically-coupled, non-positive or forced closure (11, 13), a partially flexible first bag (3) and second bag (5), a support element for holding containers, a clamping and actuating mechanism (17), a clamping and actuating frame (21) to modify a relative position of the containers, and a drive unit. The agitator for hermetic mixing of active agent with carrier- and auxiliary materials, comprises a hermetic, detachable anchoring mechanism (15) for reversible opening and closing and for the hermetic transfer of a fluid particulate material containing a first and a second component of a mechanically-coupled, non-positive or forced closure (11, 13), a partially flexible first bag (3) and second bag (5), a first- and second support element for holding a first and second container, a first and/or second clamping and actuating mechanism (17) for the first and the optionally second component and vice versa, a clamping and actuating frame (21) to modify a relative position of the first and second containers, and a drive unit for the adjustment of the rotation of the clamping and actuating frame for the first and the second containers. The closure is secured to one another hermetically. Openings of the bags are hermetically connected to the first and second component. The first and the second components are reversibly opened and closed again in the secured state for forming a common passage between them under the application of an equidirectional force. The bags are flexible for reversibly opening and closing of the component. The support elements are directly or indirectly connected with the clamping and actuating frame at a distance to one another. The clamping and actuating mechanisms are built as a single component. A second opening of the first bag has a third component of the closure and/or a second opening of the second bag has a fourth component of the closure. Each of the components has a slot, which are hermetically sealed by means of a sealing element and opened for filling and/or emptying of the respective container by the application of pressure in a controlled or regulated manner. The components of the closure comprise a first and second closure block containing an elastic lateral body with an inner surface, an outer surface, an upper surface and/or edge, and/or bottom surface and/or edge, a first mounting element at the first end of the lateral body with a radial, peripheral edge or peripheral edge section and/or with a first inner space for mounting a hinged joint and/or in the form of a first hinge element, and a second mounting element at the second end of the lateral body, a first and second hinged bar arranged along with the formation of a rotary swivel adjacently-placed mounting elements, and a first and second hinged joint. Cylindrical sections of the inner surfaces of the lateral bodies are placed mutually sealing one another. The mounting elements are placed adjacent to one another. Each components of the closure comprises an elastic protruding bar and/or a recessing groove at the inner surface of the lateral body of the closure blocks, and a rigid supporting frames and hinged joints. The foldable frames comprises of x number of supporting frames and x number of hinged joints, where x = 2n and n is a natural number >= 2. Each of the components includes a flexible block, whose inner side is provided with a continuous closure spring, which facilitates a reversible and hermetic closure with a groove. The first and the second blocks and/or the first and second closure elements are more or less of the same length, are connected with the formation of a closed volume. The upper surface of the first block has a continuous, third closure element and the upper surface of the second block has a continuous, fourth closure element. The closure further comprises of a fifth and/or sixth closure element at an outer surface of the first and/or second block. The components of the closure comprise a first- and second flexion and/or stretchable elastic element, which is placed or lies at the outer side of the lateral body of the first block or is connected with the lateral body of the first closure block. The first flexion and/or stretchable elastic element have oppositely-lying first and second ends. The components of the elastic flexion element comprise of a strut, a bar and a block. The hinged bar is arranged along with the formation of a rotary swivel adjacently-placed mounting elements of the closure blocks. The clamping and actuating mechanism comprise of a first and second mounting and/or locking mechanism for a flush mounting and/or locking of the first and second hinged element and/or the hinged bar, and an adjustment mechanism, which moves the first mounting and/or locking mechanism and the second mounting and/or the locking mechanism. The clamping and actuating mechanisms are operated manually, pneumatically, hydraulically or in a motorized manner while opening or closing the detachable anchoring mechanism. The first and the second support elements are connected with a rotary holding mechanism for the first and second containers. The first bag and/or the second bag taper towards the components of the closure. The first support element is at a distance from the second component of the non-positive or forced closure that is longer than its distance from the first component of the non-positive or forced closure and vice versa. The inner surface of the lateral body of the first and the second closure blocks is placed partially sealing one another and is reversibly opened under the effect of force, while forming a passage between them. An independent claim is included for a procedure for hermetic mixing of active agent with carrier- and auxiliary materials in the agitator.
