Abstract: The spray assembly of a dispensing device is arranged together with a mixing assembly inside a mixing and spray head, the mixing assembly being arranged before the swirl chamber of the spray assembly, and the mixing and spray head, which forms a unit, being removably attached to a multicomponent dispensing appliance. The result is a more homogeneous spray action, on one hand, and an easy replacement of the head, on the other hand.

Abstract: A mixing and discharging device (1) has a syringe-like container (10), in which a plunger can be moved. A press-out spindle (30) having an external thread (31) interacts with a counterpart (40) by means of a thread engagement. The counterpart comprises one or more thread segments, which can be deflected outward in order to release the thread engagement. A securing element (5) can be slid onto the counterpart (40) in a distal direction in order to prevent a release of the thread engagement. A mixing rod (61) extends through the plunger (20). An operating element (70) is connected to the proximal end of the mixing rod by means of a releasable form closure or force closure. A locking element (80) can be moved between a locking position and a release position. In the locking position, the locking clement prevents a release of the form closure or force closure. Insulating ribs (13) minimise the input of heat into the interior of the container due to touching.

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.

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.

Abstract: A device for opening an ampoule (3) comprises a hollow cylindrical housing (11) having an interior for accommodating the ampoule (3) and a rotary element (12) having a proximal section (121), to which a break-off section (124) extending in a distal direction is connected to. The break-off section (124) is flexible in a radial direction and is pivotably connected to the proximal section (121) in the radial direction. The rotary element (12) is rotatable relative to the housing (11) about the longitudinal axis. The housing (11) has a first guiding structure (119) for pressing the break-off section (124) inward during a rotation of the rotary element so that the break-off section (124) exerts a radial shear force on an ampoule head (33) of an ampoule (3) to break the ampoule head (33) off of the ampoule body (31).

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.
