During said long period of time, a) there is at least one time interval during which the TTS adhering to the surface of the skin is intensively exposed to water, and b) the active ingredient is transdermally released. The invention also relates to a method for the continuous transdermal release of at least one pharmaceutical active ingredient over a long period of time.

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.

Abstract: The invention describes a tensioning rail (3) for a membrane (2) of a membrane press. To allow a simpler and more rapid assembly and disassembly of the membrane (2) than in known devices, the tensioning rail includes a support rail (8), in which at least one tensioning strip (13) is mounted detachably, whereby the tensioning strip (13) is designed for securely clamping onto the edge of the membrane (2). In this way it is possible to equip a new replacement membrane (2) with tensioning strips (13) independently and outside of the membrane press, which then only need to be attached to the support rail (8). In this case the support rail does not need to be disassembled, but remains on the membrane press the whole time. A further essential advantage is that the tensioning rail (3) can also be installed into existing membrane presses, for example as a replacement for an existing securing device for the membrane.

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.

Abstract: It is a matter of a container assembly with at least one stackable container (1) which has a first engaging structure (48) on its top side (19) and a second engaging structure (49) on its underside (18). The engaging structures (48, 49) are so matched to one another that, when two containers (1) are stacked together, they engage in one another in such a way that the containers are secured against shifting relative to one another at right-angles to the stacking direction and at the same time the upper container is prevented from lifting at least in certain areas. The first engaging structure (48) consists of engaging recesses (54) and the second engaging structure (49) of engaging projections (55). Feet (57) provided on the underside (18) of the container (1) are designed as elements of the second engaging structure (49) and are able to engage the first engaging structure (48) from the rear, to prevent lifting of the upper container at least in certain areas.
