  • Patent number: 9308506
    Abstract: A mixing apparatus for mixing at least two components comprises a mixing chamber having a first component and at least one component chamber having a further component. The component chamber is connected to the mixing chamber by a feed line. A negative pressure device generates a negative pressure in the mixing chamber in the starting position. By activating the negative pressure device, the pressure is equalized, whereby the further component is transferred into the mixing chamber. A display apparatus is provided at the component chamber to display a pressure change in the component chamber. The display apparatus is preferably formed by elastic bellows provided at one end of the component chamber, which is disposed opposite of the end of the component chamber following the feed line.

  • Patent number: 8944107
    Abstract: An opening device for opening a closed fluid container comprises a housing having a first chamber (1) for receiving the fluid container (3) and a second chamber (2) having an outlet (13). A part (6) of the fluid container that can be separated is arranged in the second chamber. A rotary drum (8) is rotatably supported in the second chamber. Said drum can be rotated from a starting position into a separating position in which it separates the separable container part from the fluid container. The rotational axis of the rotary drum is disposed at an angle to the connecting axis between the first and second chambers. A system for mixing at least two components uses such an opening device and a mixing container (18) having a connecting piece (19), to which the opening device is removably connected to establish a fluid connection.

  • Patent number: 8936391
    Abstract: The static mixer has a coupling section and a mixer housing in which mixer elements are arranged consecutively in the flow direction so as to be offset relative to one another by an angle, and are designed so as to apply an alternatingly directed rotation to the mixed material during the mixing operation. A mixer element has two transversal walls that are divided into sectors, the first transversal wall comprising sectors that are separated by an inflow separating wall directed to the inlet, and a separating wall directed to the outlet, the transitions between the sectors and the separating wall forming respective breakaway edges, the separating wall being arranged at an angle relative to the inflow separating wall, and the second transversal wall, which is divided into sectors, having an outflow separating wall directed to the outlet. Such a mixer allows a more efficient mixture particularly of very quickly reacting components and is also suitable for small dimensions as used in medicine.

  • Patent number: 8690012
    Abstract: The dispensing assembly comprises a double cartridge having two storage containers with bags placed therein, a mixer that is connectable to the cartridge, and an opening means acting upon the bag. The opening means is arranged on the mixer housing and rotatable with respect to the cartridge and in one exemplary embodiment has a cutting member with two knife-edges that are arranged essentially parallelly to and spaced apart from the longitudinal axis and provided with cutting edges. Thanks to the rotatable knife-edges, such a cutting member allows a clean and predetermined opening of the bags and a dispensing operation with minimum pressure losses and lost volumes.

  • Patent number: 8622244
    Abstract: A dispensing assembly includes a double cartridge having two storage containers with bags placed therein, a mixer that is connectable to the cartridge, and an opening device acting upon the bag. The opening device is arranged on the mixer housing and rotatable with respect to the cartridge and has a cutting member including two knife-edges that acts essentially perpendicular to the longitudinal axis of the bags within the cartridge. Due to the knife-edges being rotatable and arranged laterally with respect to the bags, the cutting member allows a clean and predetermined opening of the bags and a dispensing operation with minimum pressure losses and lost volumes.

  • Patent number: 8590747
    Abstract: A dispensing appliance for a double cartridge comprises a housing for receiving multiple components and a rotatable portion having a thread, the two parts cooperating in such a manner that by rotating the rotatable portion, a multiple plunger acting upon the pistons in the housing is continuously displaceable relative to the housing in the dispensing direction. To this end, the housing is configured to comprise at least two adjacent storage containers, and the thrust force of the rotatable portion is directly transmitted to a multiple plunger. The rotatable portion may have an internal thread and the double plunger a feed flange with a corresponding external thread, in order to actuate the latter in the axial direction upon rotation of the rotatable portion. This arrangement allows dispensing even highly viscous materials with little manual force under high pressure in a precisely metered manner.

  • Patent number: 8517226
    Abstract: The dispensing assembly with a syringe comprising storage container configured to receive a powdery or granular material and a piston that is connected to a hollow ram. In order to supply a liquid to the powdery or granular material, both the hollow ram and the piston have through-going, sealable longitudinal bores. Due to the fact that the liquid is filled in from the inlet side, a complete de-aeration of the mixture can be ensured.

  • Patent number: 8376187
    Abstract: The dispensing assembly includes a cartridge having at least two containers and accessories. The fastening area (6) of the cartridge (1) and the fastening areas (9) of the accessories (4) are configured such that the accessories are attachable to the cartridge by plugging them on without a twisting motion and removable therefrom by twisting them one relative to another. In a further developed embodiment, the parts comprise coding elements which serve as aligning means and for preventing that the accessory is plugged onto the cartridge in the wrong orientation. An assembly of this kind allows an easy attachment and removal of an accessory such as a mixer or a closure cap and can be produced inexpensively.

  • Patent number: 8313232
    Abstract: A dynamic mixer for mixing components in different volumetric amounts comprises a rotor housing which is closed on the inlet side thereof by a cover, the cover defining inlets for the components. The inlet for the first component having the larger volumetric amount leads to an antechamber that communicates with a following mixing chamber by at least one passage. The mixing rotor includes a distributor body located in the antechamber for distributing the first component around the axis of rotation of the mixing rotor. The inlet for the second component having the smaller volumetric amount leads to at least one inlet opening located in the area of the passage to the mixing chamber transversely to the axis of rotation.
