Definitions

  • the invention relates to a chemical container according to the preamble of claim 1.
  • a chemical container should be able to be used in particular for a metering pump in drinking water treatment.
  • the object of the invention is to provide a chemical container of the generic type with which the above disadvantages are avoided and with which, in particular, contamination and contamination of the dosing agent by air supplied is avoided.
  • a first embodiment is described below with reference to FIGS. 1 to 3.
  • a chemical container 1 has a neck 3 enclosing an opening 2 on its upper side.
  • a tight tear-off closure 4 is welded, which is formed from a material impermeable to the contents of the container.
  • the tear-off closure 4 has, in the manner customary for such a tear-off closure, a weakening line 5 which determines the tear-off cross section and a tear ring 6. By pulling the tear ring 6, the opening of the chemical container is released.
  • the neck 3 has an external thread 7, onto which an attachment part designed as a union nut 8 is screwed.
  • the union nut 8 has at its end facing away from the container an annular extension forming an inwardly extending stop 9 and an inwardly adjacent sealing device in the form of a sealing ring 10.
  • annular dirt and bacterial filter 11 is arranged between the annular stop 9 and the outer surface of the tear-off closure 4. It is firmly clamped in its position by means of the screwed union nut.
  • the external thread of the neck 3 and a corresponding internal thread of the union nut 8 are matched to one another in such a way that a threaded gap 12 results.
  • this thread gap is limited by the filter 9. Air flowing through the outside of the threaded gap 12 must therefore pass through the filter 11 and is sterilized by it.
  • the outer lip of the sealing ring 10 extends to the surface of the tear-off closure 4.
  • the filter 11 is thereby covered against contamination from the outside by the sealing ring 10, and the container contents are sealed off by the tear-off closure 4 themselves.
  • the tear-off closure 4 is now opened by pulling on the ring 6.
  • the tear-off closure 4 is then opened in the manner best shown in FIG. 3 and a suction pipe 13 is introduced as a chemical suction lance through the opening 2 into the interior of the container and into the container contents 14 to be sucked into a dosing device.
  • the suction pipe leads in a known manner via a connection 15 indicated to a metering pump.
  • the sealing ring 10 has an inner diameter which is smaller than the outer diameter of the intake pipe 13 to be inserted.
  • the sealing ring is preloaded so that it is with Tension is applied to the outside of the intake pipe and thus closes the opening 2 airtight to the outside.
  • the sealing ring is preferably made of a somewhat elastically yielding material.
  • the only connection between the interior of the chemical container and the external atmosphere is via the threaded gap 12. If dosing means 14 is now drawn in by the metering pump, a negative pressure is created which is compensated for by air flowing in via the threaded gap 12. Since the inflowing air flows through the filter designed as a dirt and bacterial filter, it is cleaned and sterilized, so that there is no contamination of the dosing agent 14 contained in the dosing container.
  • FIGS. 1 to 3 is practically a one-way closure with a one-way filter.
  • Fig. 4 an embodiment is shown in which the closure with the filter is designed to be reusable.
  • the chemical container 1 shown in FIG. 4 in turn has a neck 3 forming an opening 2, which has an external thread 7 on its outside. As long as the container is closed, a cap closure is screwed onto it.
  • the suction lance 16, which can be connected to the metering pump via an indicated connection 15, has an intake pipe 13, on the surface 17 of which a filter holding ring 18 is slidably provided.
  • the filter holding ring 18 is designed in the manner of a cap that can be plugged onto the thread. But it can also be a cap with an internal thread, so that the filter holder ring can be screwed onto the external thread of the neck 3.
  • the filter holder ring On its lower surface opposite the outer surface of the neck 3, the filter holder ring has an annular stop Groove 19, which receives a dirt and bacteria filter 11.
  • the filter 11 By plugging or screwing the filter holder ring 18 onto the external thread surface of the neck 3, the filter 11 is firmly clamped as in the first embodiment, in such a way that the filter in turn has an existing thread or air gap 20 between the external thread and the filter holder ring Closes opening 2.
  • a sealing ring 21 is also provided in the interior of the filter holding ring 18 in the second embodiment, the inside diameter of which is smaller than the outside diameter of the suction pipe 13.
  • the filter holding ring is again made of an elastically yielding material, so that the sealing ring 21 is itself bears on the surface 17 of the suction pipe 13 and forms an airtight connection.
  • An annular abutment 22 is formed on the surface 23 facing away from the container.
  • the suction lance 16 has a section 24, the diameter of which is larger than the diameter of the suction pipe 13.
  • the lower surface 25 of the section 24 facing the container forms a second abutment opposite the abutment 22.
  • a compression spring 26 is provided between these two abutments 22, 25. This compression spring 26 presses the filter holder ring 18 firmly onto the chemical container, so that the filter 11 remains clamped in its position.
  • annular projection 27 projecting beyond the surface 17 is provided on the outer surface 17 of the intake pipe 13. This is at such a distance from the lower surface 25 that it comes to lie in the opening 2 at a distance from the filter holding ring 18 in the manner shown in FIG.
  • the suction lance 16 is off removed from the chemical container 1, then the annular projection 27 engages the filter holding ring 18 and lifts it together with the filter 11 clamped in the annular groove 19 from the clamp seat upwards from the neck 3.
  • This embodiment is therefore a reusable device.
