The invention relates to a device for removing a fluid from at least one container (), from a vial for example, said container being closed by a closure () that can be punctured. The device comprises a base body () with a container receiving portion () and a hollow needle-like puncturing organ () in order to puncture the closure () of the container () in a removal position of the container (). The aim of the invention is to enable mounting the container on the device without unintentionally puncturing the closure. This is achieved in that detent structures () are provided which retain the container () on the device in a removal position and in a mounting position which is different from said removal position. Such a device can be used in particular to fill an applicator () with one or more fluid reservoirs from one or more vitals.

An opening device for opening a closed fluid container comprises a housing having a first chamber () for receiving the fluid container () and a second chamber () having an outlet (). A part () of the fluid container that can be separated is arranged in the second chamber. A rotary drum () 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 () having a connecting piece (), to which the opening device is removably connected to establish a fluid connection.

A discharge apparatus for discharging a product having compressed gas support comprises a container () having a discharge opening () and a pressure element (), which is mounted displaceably in the container (). A counterpressure element () is provided on the container () and is used to advance the pressure element () into the container in order to absorb a developing counterpressure when pressure is applied onto the pressure element (). A compressed gas device () dispenses compressed gas in the region of the discharge opening (), and comprises a valve () and a valve actuating device () to control the compressed gas dispensing. The actuating device () is provided on the counterpressure element () to ensure that when discharging the product from the container, at the same time the compressed gas device can be actuated by applying pressure onto the pressure element, whereby compressed gas exits the discharge opening at the same time as the fluid product.

Proposed is a dispenser for discharging at least one flowable component from a cartridge. The dispenser comprises a cartridge holder () and an advancing element () that is slidable therein. A cartridge () can be axially inserted into the cartridge holder against a direction of advancing (V). In order to axially fix the cartridge, a rotating element () has been provided on the cartridge holder. In a first orientation the cartridge can be slid into the cartridge holder against the direction of advancing, while in the second orientation the rotating element axially fixes the inserted cartridge. Furthermore, in a third orientation the rotating element can be rotatable on the rotary axis in order to open at least one outlet opening of the cartridge.

A spraying device having a spray head for spraying at least one component comprises at least one substance component duct (), the component outlet (') of which leads out of a spray head tip (). An annular duct () for a pressurized gas surrounds the at least one component duct () at least partially in the longitudinal direction and leads out of the spray head () at the spray head tip (). A pressurized gas supply duct () is provided for introducing pressurized gas at the annular duct (). The annular duct () has a plurality of ribs (&#x2032;), which divide the annular duct () at least in the region of the spray head tip () into pressurized gas outlet ducts (&#x2032;) that are separated from each other.
