DETAILED DESCRIPTION OF THE DISCLOSURE

(15) As described hereinafter, according to the present disclosure a transport structure serves for the temporary, non-sterile storage and transport of a plurality of vials (hereinafter also referred to as containers) for the storage of substances for medical, pharmaceutical or cosmetic applications in a regular arrangement, for example in a matrix arrangement with regular distances between the containers along two different spatial directions, preferably along two mutually orthogonal spatial directions. For this purpose, the transport structure has no sterility barrier, in particular no circumferential sterile sealing between the bearing member and the accommodation member and no sterile protective foil or film for sterile sealing of the transport structure. Rather, the vials are stored or transported in the transport structure under non-sterile conditions. If sterile conditions are required for storage or transport of the containers, this is rather accomplished by means of at least one sterile outer packaging bag, which accommodates at least one transport structure, for example by means of a plastic tube, in which a gas-permeable, sterile protective film may be provided in portions, which may, for example, be formed by a braid of plastic fibers, such as polypropylene fibers (PP), or a Tyvek® protective film, to allow sterilization of the inner volume of the outer packaging bag and the outside of the transport structure by a flow of a sterilizing gas flowing into the outer packaging bag.

(16) According to FIG. 1a, the transport structure 1 comprises an accommodation member having a plurality of frustro-conical receptacles in which the vials are accommodated and a substantially plate-shaped bearing member, which are detachably connected to each other by means of latching structures 38, 42 which will be described in more detail below.

(17) According to FIGS. 2a to 3c, the accommodation member 10 is formed by a flat base plate 11 from which a plurality of frustro-conical receptacles 14 protrude, which are formed by circumferential side-walls 15 and which are closed at their upper ends by closed bottoms 16, on the underside of which each four protrusions 19 are provided, so that the upper ends of the vials to be accommodated are accommodated at a distance from the bottoms 16 of the receptacles 14. The inner diameter of the receptacles 14 decreases from their open ends to the bottoms 16; preferably the inner diameter decreases continuously, corresponding to the vials to be accommodated. The outer diameter in the region of the bottoms and cylindrical side-walls is larger than in the relatively short neck portion with the filling opening.

(18) For stiffening the accommodation member 10, the side-walls 15 are connected to each other via stiffening ribs 18, which in turn are connected to the base plate 11 and which are particularly designed integrally with the base plate. For further reinforcement of the side-walls 15, these comprise several ribs extending in the longitudinal direction of the receptacles 14. The receptacles 14 are disposed in a two-dimensional regular arrangement, namely along rows extending in the y-direction, with adjacent rows being offset to each other by half a distance between the receptacles 14. Other arrangements of the receptacles 14 are also possible, for example in a two-dimensional matrix arrangement along rows and columns in the y-direction and x-direction, respectively, at even distances from each other.

(19) The accommodation member 10 is formed in one piece by thermoforming a plastic material, in particular by deep-drawing a thin film or a thin film plate from a plastic material having a material thickness of up to 1.0 mm, preferably having a material thickness of up to 1.25 mm and even more preferably having a material thickness of up to 2.0 mm. PET, PS or PP is preferred as plastic material, wherein also multi-layer films may be used (e.g. PSEVOHPE/PPEVOHPE . . . ). Conveniently, this plastic material is transparent to allow a visual inspection of the vials accommodated in the receptacles.

(20) As can be concluded from FIG. 2b, a raised edge 12 extends essentially perpendicularly from the base plate 11. The lower edge 13 of the accommodation member 10 spans a common plane extending in parallel with the plane of the base plate 11. In the plane of the base plate 11, several island-like protrusions 20 protrude laterally, on each of which latching structures 21, 23 are formed, namely outer latching structures 23 and inner latching structures 21, which are preferably identical. These latching structures 21, 23 are each formed by two laterally rounded portions, which are particularly mushroom-shaped in profile, as shown in FIG. 4, and which are connected to each other via a connecting web 22, 24 of a smaller diameter. As can be seen in FIG. 2a, the latching structures 21, 23 are hollow on their rear side due to the manufacturing of the accommodation member 10.

(21) The side-walls 15 of the receptacles 14 are slightly inclined inwards (cf. FIG. 2b), which takes into account the fact that the vials to be accommodated have a larger outer diameter in the regions of their bottoms and cylindrical side-walls than in the relative short regions of their upper neck portions. The inner diameter of the receptacles 14 in the regions of the bottoms is preferably smaller than the outer diameter of the vials to be accommodated in the regions of their bottoms and cylindrical side-walls, so that the vials can only be accommodated in the receptacles 14 in an orientation specified by the geometry of the receptacles 14, i.e. in an upright orientation, i.e. with their upper neck portions being directed towards the bottoms of the receptacles 14. Due to the inclination of the side-walls of the receptacles 14, several accommodation members 10 can be stacked one on top of the other to save space, which helps to reduce disposal costs. When stacking the accommodation members 10 one on top of the other, the upper sides of the stiffening ribs 18 of a first accommodation member 10 rest on the back of the base plate 11 of a second accommodation member 10 stacked above, so that the inwardly inclined side edges 12 are also pushed into each other.

(22) FIG. 2d shows schematically how vials 60 are accommodated in the receptacles 14 of the accommodation member. The length of the receptacles 14 is larger than or equal to the axial length of the vials 60, so that these can be accommodated essentially completely within the receptacles 14 without protruding from the lower end of the receptacles 14. The ribs 19 on the inner sides of the bottoms 16 serve as spacers so that a small gap remains between the bottoms 16 of the receptacles 14 and the upper rims 63 of the vials 60, so that the inner volumes of the vials 60 can communicate with the inner volumes of the receptacle 14 via the filling openings 65 and this gap. Generally, this enables sterilizing the inner volumes of the vials 60 while these are accommodated in the transport structure, namely by a flow of a sterilizing gas flowing into the inner volumes of the vials 60 via the aforementioned gap.

(23) FIG. 2d shows the intended orientation of the vials 60 during their storage in the transport structure according to the disclosure, namely upright within the receptacles 14, with the upper ends 63 of the vials facing the bottoms 16 of the receptacles. The bottoms 64 of the vials are essentially flush with the lower edge 13 of the accommodation member but may also be arranged completely within the volume formed by the lateral edge 12, which depends on the respective geometry of the associated bearing member, as described below.

(24) According to the plan view of FIG. 3a, the bearing member 30 comprises a substantially flat, rectangular base plate 31 the outer dimensions of which correspond to those of the base plate 11 of the accommodation member 10. As can be seen in FIGS. 3a and 3d, the upper side of the base plate 31, i.e. the side of the bearing member 30 facing the accommodation member, is flat (planar). More specifically, a plurality of supporting surfaces 31a is formed on the upper side of the base plate 31 the widths of which essentially correspond to the widths of the vials and between which relatively narrow grooves 31b are formed. When the bearing member is detachably latched with the accommodation member, the supporting surfaces 31a are arranged relative to the receptacles in such a manner that the bottoms of the vials accommodated in rows in the accommodation member rest exactly in rows on these supporting surfaces 31a.

(25) The supporting surfaces 31a jointly span a plane on which the bottoms of the vials rest when they are accommodated in the transport structure. In any case, the grooves 31b are so narrow that the vials can be pushed in any direction over the plane spanned by the supporting surfaces 31a without major ‘jerking’. The grooves 31b serve to further stiffen the base plate 31, which is particularly advantageous if the bearing member 30 is formed from a thin film or a thin film plate of a plastic material by thermoforming, in particular by deep drawing. The vials are conveniently pushed from the base plate 31 in the longitudinal direction of the supporting surfaces 31a for further processing. In principle, however, they may also be pushed from the base plate 31 in any other direction, especially transversely to the grooves 31b, as shown in FIG. 3d.

(26) Of course, according to other embodiments the upper side of the base plate 31 may also be completely flat, in particular without supporting surfaces 31a and grooves 31b described above.

(27) FIG. 4 shows an example of the positive engagement of latching structures of the bearing member and of the accommodation member with each other in a schematic cross-sectional view. The latching structures 21, 42 are each formed in the form of a mushroom head, if viewed in profile, each having a transition portion 21a and 42a, respectively, which is formed slanted in FIG. 4, but which may also be curved or which may protrude substantially perpendicularly from the respective base plate 20 and 39, respectively, an adjoining narrowed portion 21b and 42b, respectively, and a latching head 21c and 42c, respectively, which has a larger width or is formed like a mushroom head. The latching structures 21, 42 are each formed hollow, the outer dimensions of the latching structure 21 on the protrusion 20 of the accommodation member corresponding to the inner dimensions of the latching structure 42 on one of the side wings of the bearing member, so that the latching structure 42 can be pressed onto the latching structure 21 to effect the positive engagement.

(28) Several transport structures as shown in FIG. 1a can be arranged stacked one above the other, as shown in FIG. 1b. As shown in FIG. 1b, for this purpose a plurality of troughs 32 are formed on the underside of the base plate 31, i.e. on the side of the base plate 31 facing the accommodation member of a transport structure arranged above it, which extend in parallel with one another in the y-direction, each have the same width in the x-direction and the same length in the y-direction and are separated from one another by partitioning webs 33. The respective ends of the troughs 32 are rounded, but do not extend completely to the edges of the base plate 31, as shown in FIG. 3a. Thus, each of the troughs 32 is trough-shaped. The width of the troughs 32 corresponds to the outer diameter of the cylindrical side-walls 15 of the receptacles of the accommodation member, so that the closed upper ends of the receptacles are accommodated in the troughs 32 and guided laterally when two transport structures 1 are arranged stacked one above the other, as shown in FIG. 1b. The circumferential peripheral web and the rounded ends 34 of the troughs 32 on the underside of the base plate 31 prevent the upper transport structure 1 from slipping laterally relative to the lower transport structure 1. The troughs 32 and partitioning webs 33 also prevent the upper transport structure from slipping laterally in a direction perpendicular to the longitudinal direction of the troughs 32 and partitioning webs 33. Here, the troughs 32 and partitioning webs 33 serve to further stiffen the bearing member 30, so that it may also be made of relatively thin plastic plates, in particular by deep-drawing, as described below.

(29) According to an alternative embodiment, an intermediate plate 5 is placed on the respective underside of the base plate of a bearing member, as shown in FIG. 1b, on the upper side of which a plurality of troughs 6 with partitioning webs 7 formed in between are formed like the troughs 32 and partitioning webs 33, respectively, as described above in conjunction with the design of the underside of the base plate 31 of a bearing member. According to this alternative embodiment, the intermediate plate 5 is matched to the underside of the base plate of a bearing member in such a manner that the intermediate plate 5 cannot be displaced relative to the bearing member when placed on the bearing member. Furthermore, the lengths of the rows of receptacles of the accommodation member are matched to the lengths of the troughs 6 on the upper side of an intermediate plate 5 in such a manner that the two transport structures 1b cannot be displaced both in the longitudinal direction of the troughs 6 and transversely to this longitudinal direction.

(30) Thus, a plurality of transport structures 1 can be reliably stacked on top of each other to save space. In the stacked arrangement, for example as shown in FIG. 1b, the vials are arranged upside down in the receptacles of the respective accommodation member, i.e. with their upper ends or neck portions being directed downwards as shown in FIG. 1b. Of course, a plurality of transport structures may also be stacked one above the other in such a manner that the receptacles of the respective accommodation member are directed upwards and that hence the bottoms of the vials rest on the respective upper side of the base plate of a respective bearing member.

(31) On the left-hand and right-hand side of the base plate 31 in FIG. 3a side wings 35 are formed which can be pivoted or folded downward along the folding lines 35a, 35b. More specifically, each of the side wings 35 is essentially C-shaped, wherein a recessed portion 36 is formed in a central portion. At the upper and lower end of the side wings 35, latching structures 38 are formed corresponding to the outer latching structures 23 of the accommodation member (cf. FIG. 2a). A rectangular portion having an additional recessed portion 37 is formed between the base plate 31 and the side wings 35, the width of this rectangular portion corresponding to the height of the lateral edge 12 of the accommodation member 10 (cf. FIG. 2b).

(32) At the upper and lower edge of the base plate 31 in FIG. 3a, side wings 39 are formed which can be pivoted or folded along the folding lines 39a, 39b. More specifically, the side wings 39 are essentially C-shaped, wherein a recessed portion 40 is formed in the central portion. At the left and right end of the side wings 39, latching structures 42 are formed corresponding to the inner latching structures 21 of the accommodation member (cf. FIG. 2a). A rectangular portion having an additional recessed portion 41 is formed between the base plate 31 and the side wings 39, the width of this rectangular portion corresponding to the height of the lateral edge 12 of the accommodation member 10 (cf. FIG. 2b).

(33) According to another preferred embodiment (not shown), the upper side wing 39 shown in FIG. 3a is completely missing, so that the vials can then be pushed from the base plate 31 even more freely, as outlined below.

(34) The bearing member 30 is formed in one piece by thermoforming a plastic material, in particular by deep-drawing a thin film or a thin film plate from a plastic material having a material thickness of up to 1.0 mm, preferably having a material thickness of up to 1.25 mm and even more preferably having a material thickness of up to 2.0 mm. Preferably, PET, PS or PP is used as the plastic material, wherein also multi-layer films may be used (e.g. PSEVOHPE/PPEVOHPE . . . ). Conveniently, this plastic material is transparent to allow a visual inspection of the vials accommodated in the receptacles.

(35) Referring to FIGS. 2a to 3e, for forming the transport structure 1 shown in FIG. 1a, first an accommodation member 10 is arranged with the receptacles 14 facing downwards and the vials 60 are then inserted upside-down into the receptacles 14 until the upper rims 63 of the vials 60 rest on the protrusions 19 on the closed ends 16 of the receptacles 14. Then a bearing member 30 is placed on the accommodation member 10 with the upper side of the base plate 11 facing upwards, so that the bottoms 64 of the vials 60 abut against the supporting surfaces 31a of the base plate 11 of the bearing member 30 or are arranged at a short distance from them. Then the side wings 35, 39 of bearing member 30 are folded twice along the folding lines 35a, 35b and 39a, 39b, respectively, towards the upper side of the base plate 11 of the accommodation member 10 so that the latching structures 42 on the side wings 39 are then pressed onto the inner latching structures 21 of the accommodation member 10, so that the latching structures 38 on the side wings 35 of the bearing member 10 are pressed onto the outer latching structures 23 of the accommodation member 10 and so that the latching structures 21/42 and 23/38, respectively, are latched with each other, whereby bearing member 30 and accommodation member 10 are detachably connected to each other.

(36) As an alternative to the forming of the transport structure 1 shown in FIG. 1a, first a bearing member 30 may be arranged with the upper side of the base plate 11 directed upwards. Then, the vials 60 are placed upright on the supporting surfaces 31a corresponding to the arrangement of the receptacles 14 of the accommodation member 10. Then, the accommodation member 10 with the receptacles facing upwards is lowered onto the bearing member 10 so that the vials 60 are inserted into the receptacles 14 of the accommodation member 10. Then, the side wings 35, 39 of the bearing member are folded twice and the bearing member 30 is latched to the accommodation member 10, as described above.

(37) Or the vials 60 are arranged upright on a work surface (not shown) corresponding to the arrangement of the receptacles 14 of the accommodation member 10. Then the accommodation member 10 with the receptacles facing upwards is lowered onto the bearing member 10 so that the vials 60 are inserted into the receptacles 14 of the accommodation member 10. Then the accommodation member 10 with the vials 60 accommodated therein is pushed onto the upper side of the base plate 11 of the bearing member 10. Then the side wings 35, 39 of the bearing member are folded over and the accommodation member 30 is latched to the bearing member 10, as described above.

(38) Or the vials 60 are inserted upside down into the receptacles 14 of the accommodation member 10 oriented vertically downwards. Then the bearing member 30 with the upper side of the base plate 11 facing downwards is pushed onto the accommodation member 10 with the vials 60 accommodated therein. Then the side wings 35, 39 of the bearing member are folded over and the bearing member 30 is latched to the accommodation member 10, as described above.

(39) FIG. 1a shows the transport structure 1 formed in this manner. Because the vials are accommodated in the receptacles of the accommodation member and the upper rims of the vials are covered by the closed ends of the receptacles, penetration of impurities, in particular resulting from material abrasion, into the vials is reliably prevented. The side-walls of the receptacles also prevent a contact of directly adjacent vials in the transport structure and during handling, so that mechanical damage to the vials, particularly scratches, is reliably prevented.

(40) The accommodation member and bearing member are detachably connected to each other via the latching structures. Even though the side wings of the bearing member are folded down twice for latching and the latching structures are latched together, the side wings preferably do not exert any additional frictional coupling. Rather, the position of the accommodation member relative to the bearing member is preferably solely the result of the positive-fit formed by the latching structures.

(41) A plurality of such transport structures can be stacked on top of each other. Here, intermediate plates are preferably arranged between the transport structures, as shown in FIG. 1b.

(42) In the configuration of FIG. 1a, the transport structure with the vials accommodated therein under non-sterile conditions can be transported. Or, in the configuration of FIG. 1b, a plurality of transport structures with the vials accommodated therein under non-sterile conditions can be transported stacked on top of each other. The transport structure according to the present disclosure preferably is to serve for the transport of vials not yet sterile packaged, for example to a pharmaceutical filling company, where the vials are filled after cleaning and sterilization.

(43) If a transport in the transport structure according to the present disclosure is nevertheless desired under sterile conditions, for example the transport of cleaned and sterilized vials to a pharmaceutical filling company in a ‘ready to use’ (RTU) state, the transport structure with the vials accommodated therein is cleaned and sterilized and placed in at least one sterile outer packaging bag, for example in a plastic tube, which is then sterile sealed. This sterile outer packaging bag(s) is then opened again under suitable sterile processing conditions for further processing, for example at a pharmaceutical filling company.

(44) The procedure for opening the transport structure of FIG. 1a and transferring the vials accommodated therein to a processing station, for example a filling station at a pharmaceutical filling company, is as follows:

(45) First, the transport structure together with the bearing member facing downwards is placed on a work surface. Then the latching of the latching structures 38, 42 of the bearing member 30 with the latching structures 21, 23 of the accommodation member 10 is released from above the transport structure 1, i.e. from the side of the accommodation member, without lifting the accommodation member 10. For a manual handling, the gaps between the side wings 39 and the latching structures 38 or laterally of the side wings 35 are available, as shown in FIG. 1a. In the case of an automatic or semi-automatic handling, grippers or the like engage with these interspaces. Then the side wings 35, 39 are folded back. While the side wings 35 do not need to be folded down completely, at least the side wing 39 must be completely folded down at one of the ends of the supporting surfaces 31a on the upper side of the base plate 31 so that the vials can be pushed from the supporting surfaces 31a and from the base plate 31.

(46) The vials are then pushed from the supporting surfaces 31a and from the base plate 31 by a relative displacement of the accommodation member 10 and the bearing member 30. The relative displacement between accommodation member 10 and bearing member 30 may be guided laterally and may only be possible in one direction, namely in the y-direction, for which purpose, for example, the two side wings 35 may be used in a position folded halfway upwards. For the relative displacement, preferably the bearing member 30 is temporarily fixed, for example on the supporting surface, and only the bearing member 10 is displaced in the y-direction.

(47) In this way, the vials 60 are pushed from the base plate 31 of the bearing member 30 and thus fed to the downstream processing station. According to the present disclosure, no turning of the transport structure 1 is required for feeding.

(48) According to a preferred embodiment, the bearing member comprises only two folding side wings disposed along two opposite sides. This offers additional advantages, especially for processing stations to be loaded manually or semi-automatically with prior separation of the vials, for example by means of an insulator with a rotary carousel. For this purpose, the accommodation member and the bearing member are rectangular if viewed in a plan view, with longer sides, on which, for example, the two side wings may be provided on the bearing member, and with two shorter sides. First, the transport structure is placed on a supporting surface which merges into a conveyor path to the processing station, wherein the width of the conveyor path corresponds to the length of the shorter sides. When being placed on the supporting surface, the longer sides are aligned transversely to the conveyor path. First, the latching structures are released. The transport structure is then rotated by 90 degrees so that the longer sides extend in parallel with the conveyor path. Then the two side wings are folded down. The accommodation member is then moved in the direction of the conveyor path. In this process, the vials accommodated in the accommodation member are pushed from the bearing member onto the conveyor belt via one of the two shorter sides, from where they are then conveyed to the processing station, for example via a conveyor belt or via a rotary carousel of an insulator for separating the vials.
