  • the tube 52 is pivoted against the direction 66 into the insertion opening 65, it is initially prestressed in its longitudinal direction by the tension ramp 68 until it reaches the bottom 67 parallel to its end face and then strikes the U-crosspiece.
  • the securing member 64 is provided at the free end of a radial arm 69 which projects directly adjacent to the associated end of the part 27 or 30 from the widest sleeve end of the body 3 projecting therefrom and is designed as a spiral spring arm.
  • the arm 39 merges in one piece into the body 3 and the one-piece securing member 64, it being able to deflect resiliently only in the longitudinal direction of the tube 52 or the axis 9 by appropriate profiling.
  • a substantially sealed closure is provided, which can be repeatedly opened and closed again non-destructively, surrounding the associated tube end at least over part of the outer circumference and / or sealingly sealingly with a projection into the interior of the tube or Exhaust opening 8 engages, which can also be designed as an atomizer nozzle.
  • the closure 70 is formed by the securing member 64 or the bottom 67 thereof, so that at the same time when it is transferred to the securing position the outlet opening 8 is closed without additional manipulations.
  • the device 1 can be worn hanging on the positionally secured rod 52 as a handle without the position securing means being able to be released.
  • the securing member 64 also positively prevents movement of the tube 52 parallel to the common axial plane with the axis 9.
  • the designs according to the invention can also be used for a discharge device, the storage contents of which can be completely discharged in a single, rectified lifting movement.
  • the inner circumference of the accumulator expediently forms the running surface for the pump piston, or the accumulator itself forms the pressure chamber or pump cylinder, which can be shifted or stopped step-wise or continuously or continuously continuously on the pump piston relative to the body 3 or 50.
  • the actuating bodies 16, 17 of the actuating drive 12 can also be formed by one or two end toothings and, for the driving or locking engagement in the respective toothing, each by a swivel arm which can be moved resiliently in the axial direction and which is expediently attached to the detection or display element 21 is provided.
  • the discharge device 1 can be placed with the base of the storage device or the like in a self-stable manner on a standing surface, such as a table, and the beak 52 can be directed over or into an adjacent glass or similar vessel such that the escaping medium in this vessel is caught.
  • the vessel jacket can engage between the beak 52 and the outer circumference of the unit 2, 30, 50.
