Description

[0038] Throughout the description, the claims and the drawings, those terms and associated reference signs are used as are listed in the List of Reference Signs below. In the drawings,

[0039] FIG. 1 is a perspective view of a holder according to the invention,

[0040] FIG. 2 is a bottom view of the holder with petri dishes inserted therein and slides moved into their closing position;

[0041] FIG. 2b is a bottom view of the holder with slides moved into their opening position;

[0042] FIG. 3a is a perspective view of the loaded holder and a rack; and

[0043] FIG. 3b is a perspective view of the holder and the loaded rack.

[0044] FIG. 1 is a perspective view of a holder 10 according to the invention for storing and transporting petri dishes as shown in FIG. 2a.

[0045] The carrier 10 has a housing 14 with a central axis M, an upper side 16 and an underside 18 opposite to the upper side 16.

[0046] Formed in the housing 14 are four receptacles 20 for petri dishes which extend between the upper side 16 and the underside 18 parallel to the central axis M. Each receptacle 20 has a wall 22 formed by the housing 14 and having a part-circular cross-section and which is open along its entire longitudinal extension on the side facing away from the central axis M. The receptacles 20 are both open towards the upper side 16 where they each have a loading opening 20a for loading the holder 10 with petri dishes, and towards the underside 18 where they each have an unloading opening 20b for unloading the petri dishes. Of course, it is also possible to unload petri dishes via the loading opening 20a and to load them via the unloading opening 20b.

[0047] Each wall 22 has two grooves 24 each in it which are parallel to the central axis M and open towards the underside 18. The grooves 24 are adapted to permit engagement of rods of a rack described with reference to FIG. 3a and 3b.

[0048] Provided on the exterior of the housing 14 is a label holder 30 which extends parallel to the central axis M and is open toward the top 16. A label can be inserted in this label holder 30 for safely identifying the holder 10.

[0049] On the upper side 16, an extensible carrier handle 26 is provided. This view shows the carrier handle 26 in its retracted state in which it is inserted into a centrally located retraction opening 28 so as to save space. For the convenient transport of the holder 10, the carrier handle 26 can be pulled out of the retraction opening 28.

[0050] Furthermore, eight recesses 32 are provided on the upper side 16 of the housing 14 which are arranged in pairs each between two loading openings 20a for clearly identifying each receptacle 20. For this purpose, the two recesses 32 which directly abut on the same loading opening 20a are marked with the same letter A, B, C or D. Instead of letters, numbers, symbols or colors can also be used.

[0051] Adjacent to each of the four pairs of recesses 32, a recess 34 each is provided radially further outwards on the upper side 16. Matching the recess 34, a projection 36 is provided on the underside 18 of the housing 14. When a plurality of holders 10 are stacked on top of each other, the projections 36 will engage the recesses 34 so as to obtain a positive connection between the projections 36 and the recesses 34. A plurality of holders 10 can thus be stacked on top of each other in a stable manner.

[0052] On the underside 18 of the housing 14, slides 40, 42 are provided for opening and closing the unloading openings 20b. The slides 40, 42 are described in more detail with reference to FIGS. 2a and 2b.

[0053] FIG. 2a is a bottom view of the holder 10 with petri dishes 12 loaded into the receptacles 20 and the closure mechanism 38 in its closing position, in which the petri dishes 12 are covered by the slides 40, 42.

[0054] The slides 40, 42 are arranged in pairs and offset from each other concentrically relative to the central axis M of the housing 14. The slide pairs 40, 42 are coupled via a transmission 44, in particular of the planetary type, and can be connected to a drive. The transmission 44 comprises gears 46, 48 which mesh with the slide pairs 40, 42. The gears 46, 48 are mounted on a basic body and are made to rotate by the drive. Rotation of the drive causes the slide pairs 40, 42 to move from an opening position to a closing position thereof, which latter is limited by stops. As operating means, a device centrally mounted in the basic body can be provided which consists of the centering means and a cantilever and is preferably connected to a drive which is in particular located at a loading and unloading station.

[0055] FIG. 2b is a bottom view of the holder 10 in an unloaded state thereof in which the slide pairs 40, 42 are in their opening position, exposing the unloading openings 20b.

[0056] FIG. 3a is a view of the holder 10 loaded with petri dishes 12, similar to the view of FIG. 2a, before it is introduced into a rack 50.

[0057] In the rack 50, three rods 52a, 52b, 52c are provided for the stable storage of a stack of petri dishes 12, which rods are uniformly spaced from each other with respect to the circumference of the pain dishes 12. When the holder 10 is inserted in the magazine, two rods 52a, 52b each will engage the grooves 24 described with reference to FIG. 1 and made in the wall 22 of the respective receptacle 20. The respective third rod 52c will be located at the position where the associated receptacle 20 is open on its side facing away from the central axis M.

[0058] FIG. 3b is a view of the holder 10 in an unloaded state thereof, similar to the view of FIG. 2b, following its introduction into the rack 50. The petri dishes 12 are now stored between the rods 52a, 52b.

[0059] Owing to the fact that the unloading opening 20b is arranged remote from the loading opening 20a on the underside 18 of the holder 10, a plurality of complete stacks of petri dishes 12 can be inserted simultaneously into a rack 50 and left there, for example following transport from a storage place to an analysis device, after operating a closure mechanism comprising the transmission 44 and the gears 46, 48 and moving the slides 40, 42 into an opening position thereof. The stability of the stack arrangement will not be jeopardized at any time and the petri dishes 12 will remain in the rack 50 after removal of the holder 10.
