Definitions

  • the present invention relates to a mixing device for pharmaceutical, cosmetic and the like. Products according to the Preamble of claim 1.
  • Such a device is known in the art commonly used and known, such as from DE 42 16 252 C2.
  • This known device comprises an i.w. cylindrical Plastic housing, which at one end of a unscrewable Cover can be closed with a centric Breakthrough at the same time as a guide for the drive shaft a reaching into the container mixing tool serves. At the other end is the case of an inserted Closed, which, during a later, possible Metering operation with this device, by manual impressions allows the metered removal of the mix.
  • a known device is in particular with regard to a fully automatic filling only conditionally suitable and, moreover, has only a limited Ease of use on: So 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, by a user if necessary, opening to be opened, again locked. Not only is such handling cumbersome, beyond that is the automation of this Processes difficult.
  • One-time mixing tool namely a mixing element, which after mixing by mixing the im Container recorded mixed material remains in the container interior, and only a drive shaft for the mixing tool through a (correspondingly smaller) opening in the container lid or soil is removed.
  • Blending tool also contacted the respective container ends; a holding or Fixiervorsprung for the mixing disk would therefore be highly likely from the rotating Scraped off or made ineffective, so that thereby not only a release of the mixing tool from the drive shaft after completion of the mixing process difficult to is impossible, but also scraped off plastic particles contaminate the mix.
  • Object of the present invention is therefore to provide a generic Mixing device for pharmaceutical, cosmetic or the like.
  • a disposable mixing element such as a disposable mixing disk, is possible and in particular solving this Mixing element of the drive shaft unit after completion the mixing process made more reliable and simplified can be.
  • the drive shaft unit is advantageous as a multipart Unit realized with outer shaft and inner shaft, wherein in mixed operation, preferably both shafts synchronously with each other run and the one of the waves to power the Mixing element with a suitable, externally provided drive unit connected is.
  • the other provides the waves by a caused by the relative rotation Locking the Mischeineinents relative to the drive shaft unit in the axial direction for that, on the one hand during the mixing operation the additional, axial guiding of the mixing element (also referred to as mixing tool hereinafter) is possible, for example in the way described Aufund Abddling for mixing pharmaceutical products.
  • the relative rotation between the shafts for fixing the mixing element in the direction of Provide the drive direction of rotation of the drive shaft unit.
  • the mixing element disc-shaped form and the coupling of the inner shaft and Outer shaft by means of a projection or recess realized driving clutch on the one hand and by means of a caring for the axial fixing undercut on the other hand to realize.
  • a mechanical training can be used in particular as a plastic injection molded part Inexpensive manufacture in mass production.
  • the rotary drive of the mixing element on preferably by one or a plurality of driver projections at the front of the outer shaft, to realize while the inner shaft then by means of a web-shaped, preferably transverse to the axial direction latching element can fix the mixing element in the axial direction.
  • inner shaft and outer shaft at least in the mixing element fixing operating position in their rotational position relative zueianander latching fix, here is an outer left on the Outer shaft acting locking device has proven particularly useful. This will ensure that in mixed operation Internal and external shaft rotate synchronously and not about Inertia effects or the like. the locking position of Influence mixing disk.
  • Fig. 1. illustrates in the side sectional view, as various functional components of the mixing device according to a first preferred embodiment in the mounted State interact with each other.
  • hollow cylindrical vessel part 10 made of a sprayable Plastic material is opposite to the lid 12, open end with an internal annular groove 14th in which, after the mixing process and of an internal disposable mixing disk 16 dissolved Stirring shaft unit 18 is a manual drive unit for dosing moving a piston 20 (corresponding to about the in Fig. 2 of the German utility model 297 21 534 shown unit) 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 the Vessel part 10 overlapping closure lid 24, of which a central projection 26 for engaging in the removal opening 22 is formed, closable.
  • Fig. 1 for driving-side connection with a suitably designed, not shown drive unit connectable, multi-part stirring shaft unit 18 is mounted shown in the sectional view of FIG. 2; the outside wave Fig. 2 show Figs. 6 and 7 and the views of 8 and 9 illustrate the coaxial in the outer shaft 28th guided inner shaft 30.
  • a locking unit 36 consisting of a the outer jacket the outer shaft 28 surrounded ring 38, one in the ring 38th resiliently mounted locking element 40 and a ring 38th via an end formed on the inner shaft 30 breakthrough 42 guided connecting bolt 44, are outer shaft 28th and inner shaft 30 in a predetermined relative rotational position locked to each other, wherein in this position the Locking element 40 in a corresponding in the casing of the outer shaft 28 formed recess engages.
  • transverse slot 46 limited above
  • the mixing disk 16 has, as in the bottom view of FIG. 3, a central hub portion 52, which is of a ring portion 56 held on the hub portion 52 by four radially and perpendicularly extending webs, concentric is surrounded.
  • the central hub portion 52 in enlarged form, is recognizable, points, in addition to itself by the height of the Washer 16 extending aperture 50 of the hub portion
  • a pair of undercuts 60 which in the bottom view of Fig. 3 and Fig. 5 as paragraphs in Plastic material of the mixing disk 16 can be seen.
  • 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 each outer End portions of the locking web under an undercut 60 engage and so the mixing disk 16 opposite the stirring shaft unit 18 fix.
  • the mixing disk (which is advantageous already in a closed container) to the Stirred shaft unit 18 coupled, the mixing of the done in the vessel mix, both by rapid rotational movements of the stirring shaft unit to the common axis, as well as by continuous up and down Movements (i.e., movements along the axial direction) the mixing disk in the housing, leaving a homogeneous and complete mixing of the mix, also over one longer mixing period, can be done.
  • the stirring shaft unit with the ansitzenden drive unit is then ready to mix a next housing / disposable mixing disc combination make, where most preferably neither for insertion and bonding the stirring shaft unit, still for decoupling and Leading out of the same the vessel must be opened. These are especially in the pharmaceutical sector necessary conditions for hygiene and freedom from Ensures contamination.
  • FIG. 10 An alternative embodiment will be related hereafter with the mixing disk of Fig. 10 described.
  • a locking of the outer shaft relative to the inner shaft in the mixing disk setting lock state not by a separate, as shown in FIG Outer wave seated locking unit achieved, but by Projections or cams 64, which in the one shown in Fig. 10 Way, the elongated formations 54 of the central opening 50 adjacent, on the hub portion 52 of the otherwise arranged as shown in Fig. 3 constructed mixing disk are.
