Description

BRIEF DESCRIPTION OF THE DRAWING

[0036] The invention is best understood from the following detailed description when read in connection with the accompanying drawing. Included in the drawing are the following figures:

[0037] FIG. 1 shows a schematic perspective of a tray of a sterile packaging unit;

[0038] FIG. 2 shows the tray of FIG. 1 in cross-section transversely to the axial direction;

[0039] FIG. 3 shows a perspective view of a sterile packaging unit in a first embodiment;

[0040] FIG. 4 shows a perspective view of a sterile packaging unit in a second embodiment with the trays shown in FIGS. 1 and 2.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0041] The expression “dialyzer” as used below is to be understood in such a way as to include other types of filter module, too.

[0042] FIG. 4 shows a sterile packaging unit 1 with four trays 2 which are stacked on top of each other vertically and which are enveloped and held together by a shared sleeve 3. The sleeve 3 envelopes the trays 2 (essentially) fully, thereby forming the secondary packaging, so to speak. One of the trays 2 is shown in FIGS. 1 and 2. It preferably contains five dialyzer primary packagings 4, each consisting of primary packagings respectively containing one sterile-packaged dialyzer as a medical product respectively (not shown in the figures).

[0043] Each tray 2 comprises a base 5. The latter is preferably wave-like in configuration so that its upper side forms inserts 6 for the primary packaged dialyzers. The base 5 is surrounded by side walls 7, 8, 9, 10 which are connected to each other with corner sections 11, 12, 13, 14, thereby forming a frame. FIG. 2 in particular shows that the corner sections 11, 12, 13, 14 are higher than the primary packaged products 4 inserted in the tray 2. This creates a stackable dialyzer crate, so to speak.

[0044] In the embodiment shown in FIG. 3, the upper (uppermost) tray 2 of the tray stack has a lid 15 positioned on it which covers the primary packaged dialyzers and which is likewise additionally enveloped by the sleeve 3. FIGS. 3 and 4 show the sterile packaging unit 1 in a packaged state with the sleeve 3 ready for shipping. FIGS. 1 and 2 show the sterile packaging unit 1 in a state with the sleeve 3 removed, for example for storage on a user's premises and for transport from a storage depot to an application.
