Definitions

  • the present invention relates to a mixing device for pharmaceutical, cosmetic and similar products according to Preamble of claim 1.
  • Such a device is from the prior art commonly used and known, for example from DE 42 16 252 C2.
  • This known device comprises an i.w. cylindrical Plastic housing, which one end of a unscrewable Lid can be closed with a central Breakthrough at the same time as a guide for the drive shaft a mixing tool reaching into the container serves. At the other end, the housing is used by one Bottom closed, which, during a later, possible Dosing operation with this device, by manual pushing allows the dosed removal of the mix.
  • a known device is in particular only partially with regard to fully automatic filling suitable and also has only a limited Ease of use on: This is how it is with this known device necessary after completion of the mixing process remove the screw cap from the remaining container, to remove the mixing tool from the container. This is then, with a suitable one, by a user provided, if necessary, opening closure, again locked. Such handling is not only awkward, moreover, the automation of this Operations difficult.
  • a so-called disposable mixing tool namely a mixing element, which after mixing the im Mixture taken in container remains inside the container, and just a drive shaft for the mixing tool through a (correspondingly smaller) opening in the container lid or bottom is removed.
  • the object of the present invention is therefore a generic Mixing device for pharmaceutical, cosmetic or the like.
  • a single-use mixing element such as a single-use mixing disc is possible and in particular solving this Mixing element from the drive shaft unit after completion the mixing process more reliable and simplified can be.
  • the task is achieved by the mixing device with the features of claim 1 solved.
  • the drive shaft unit is advantageous as a multi-part Realized with outer shaft and inner shaft, in mixed operation, preferably both shafts synchronously with each other run and the one of the waves to drive the Mixing element with a suitable, externally provided drive unit connected is.
  • the mixing element hereinafter also referred to as the mixing tool
  • the mixing tool is possible, for example by means of the described Aufund Movement for mixing pharmaceutical products.
  • the present invention may relate to the drive shaft unit - through training with inner and outer shaft - an apparent additional mechanical effort underlie; given the fact that by successively mixing a variety of containers with only one inside the disposable mixing element per mixing station such drive shaft unit is necessary, relativized this apparent disadvantage in view of the achievable operational advantages, in particular the ease of use and Reliability, considerable.
  • the mixing element is also particularly preferred for the mixing element to be disk-shaped train and the coupling of inner shaft and External shaft by means of a projection or recess realized driver clutch on the one hand and by means of an undercut providing axial fixation on the other hand.
  • a mechanical training can be used in particular as a plastic injection molded part Low cost mass production.
  • the rotary drive of the mixing element preferably by one or a plurality of driver projections on the face of the outer shaft, to realize while the inner shaft is then preferred by means of a web-shaped locking element running transversely to the axial direction can fix the mixing element in the axial direction.
  • the inner shaft and outer shaft at least in the operating position fixing the mixing element latching relative to each other in their rotational position fix, with a container external to the External shaft acting locking device has proven particularly useful. This ensures that in mixed operation Turn the inner and outer shaft synchronously and not Inertial effects or the like the locking position of the Influence the mixing disc.
  • Fig. 1. illustrates in the side sectional view how various functional components of the mixing device according to a first, preferred embodiment in the assembled Interact with each other.
  • One with one one-piece molded cover 12 hollow cylindrical vessel part 10 from an injectable Plastic material is on the cover 12 opposite, open end with an internal annular groove 14 provided, in which, after the mixing process and from an internal disposable mixing disk 16 released Stir shaft unit 18 a manual drive unit for dosing movement of a piston 20 (corresponding approximately to the in Fig. 2 of the German utility model 297 21 534 unit shown) can be used.
  • a Removal opening 22 in the lid portion 12 of the cylindrical Vessel part 10 is in the manner shown with a Vessel part 10 overlapping cover 24, of which a central projection 26 for engaging in the removal opening 22 is formed, closable.
  • FIG. 1 for connecting on the drive side to a suitably designed drive unit, not shown connectable, multi-part agitator shaft unit 18 is mounted shown in the sectional view of Fig. 2; the outer shaft 2 shows FIGS. 6 and 7 and the views of FIG 8 and 9 illustrate the coaxially in the outer shaft 28 guided inner shaft 30.
  • a latching unit 36 consisting of an outer jacket the outer shaft 28 surrounded ring 38, one in the ring 38 spring-loaded locking element 40 and a ring 38 via an opening formed on the end of the inner shaft 30 42 guided connecting bolts 44, are outer shaft 28 and inner shaft 30 in a predetermined relative rotational position can be snapped together, in this position the Locking element 40 in a correspondingly in the jacket of the outer shaft 28 formed recess engages.
  • transverse slot 46 delimited above also the maximum rotational stroke of a rotary movement between the two shafts 26, 28.
  • the mixing disk 16 has, as in the bottom view of FIG. 3, a central hub portion 52 formed by a ring portion 56 held on the hub portion 52 four radial and right-angled webs, concentric is surrounded.
  • These undercuts 60 are for cooperation with one provided on the engagement-side end of the inner shaft 30 Locking web 62 formed, in such a way that in a locked state, they are external End sections of the locking web under an undercut 60 grab and so the mixing disc 16 opposite fix the agitator shaft unit 18.
  • the inner shaft is also rotated relative to the outer shaft in the direction of rotation of the entire agitator shaft unit. In the twisted state so described the locking unit 36 then snaps between the shafts, such as mentioned above, a.
  • the agitator shaft unit with the attached drive unit is then ready to mix a next housing / disposable mixing disc combination to make, whereby particularly preferred neither for insertion and connection the stirring shaft unit, still for decoupling and Taking out the same the vessel must be opened. This makes them especially in the pharmaceutical sector necessary requirements for hygiene and freedom from Contamination guaranteed.
  • FIG. 10 An alternative embodiment is discussed below described with the mixing disc of FIG. 10.
  • a locking of the outer shaft relative to the inner shaft in the locking disc does not define the mixing disc by a separate, as in Fig. 2 on the outer jacket of External shaft seated locking unit reached, but by Protrusions or cams 64 that are shown in FIG Way, the elongated formations 54 of the central opening 50 adjacent, on the hub portion 52 of the otherwise as arranged in Fig. 3 mixing disc are.
