Description

Technical Field

[0001] The present disclosure relates to a molded container made of thermoplastic, in particular a blow-molded container, for accommodating medical and / or pharmaceutical preparations and for vertical stacking during transportation and / or storage. In addition, the present disclosure relates to a corresponding vertical stacking assembly or stacking system consisting of a molded container, in particular a blow-molded container according to the present disclosure. In addition, a corresponding thermoplastic molding method, in particular a blow molding method, is proposed for producing a molded container, in particular a blow-molded container, according to the present disclosure, and the use of a molded container, in particular a blow-molded container and / or a corresponding stacking assembly for accommodating and / or transporting and / or storing medical and / or pharmaceutical preparations and / or for providing preparations in application technology, in particular providing preparations in a dialysis device is proposed. Background Art

[0002] Molded containers, in particular blow-molded containers, made of thermoplastics, such as thin-walled / recyclable polyethylene terephthalate (PET), are currently used primarily in the field of beverage bottles, for example for bottling mineral water, and also as tanks for liquid cleaning / cleaning agents, solutions for daily use, etc., i.e. for use in the household or industrial sector.

[0003] In contrast, conventional plastic containers or tanks for medical and / or pharmaceutical preparations, in particular for dialysate / concentrates, are solid, thick-walled containers, which are mainly produced using (standard) injection molding methods. The problem is that such solid, thick-walled, in particular (standard) injection-molded plastic containers require a large amount of plastic material. This results in disadvantageously high raw material costs, environmental load, energy usage, machine investment and recycling costs.

[0004] Another technical problem with these solid, thick-walled, in particular (standard) injection-molded plastic containers for medical and / or pharmaceutical preparations that have been used so far is that they do not allow (almost) complete removal of the filling content by suction devices of medical devices / apparatuses provided for the proper consumption of the preparation.

[0005] Therefore, in the injection molding process, the container bottom is ideally injection molded as flat as possible. This serves, on the one hand, to avoid further increases in material consumption in the case of thicker wall thicknesses. On the other hand, it serves to reduce the flow path / required (standard) injection molding pressure. In view of valuable preparations, this is a particular disadvantage, especially for medical users.

[0006] Furthermore, the generally flat container bottoms mean that previously solid / injection-molded plastic containers for medical and / or pharmaceutical preparations cannot be stacked when the container neck is erected. This results in disadvantages in terms of the high space requirements during transport, storage and provision, with correspondingly disadvantageous cost consequences.

[0007] Another problem that arises independently in vertical stacking is that such stacking assemblies (similar to tower blocks) are unstable or shaky due to the many degrees of freedom of movement, in particular with respect to rotation about a (vertical) axial axis and / or with respect to tilting about a horizontal contact line between two containers arranged one above the other. However, in view of the high value of medical preparations and the requirements of clinical applications or procedures, the risk of tipping over is significant.

[0008] Utility model CN ​​204618983 discloses the use of a blow-molded PET container for filling hemodialysis fluid. In order to improve the quality during production, it is proposed to provide an inner rib structure protruding into the container and interrupted in sections on the inner side of the PET container as a type of flow interruption component. The flow characteristics of the hemodialysis fluid should be changed as follows, that is, in particular, in production, when filling it, it is avoided that it may be sprayed onto the outer side of the PET container, so as to avoid contamination that impairs its quality. Summary of the invention

[0009] In view of the above-mentioned prior art, the present disclosure aims to provide an improved container, preferably made of thermoplastic, for containing medical and / or pharmaceutical preparations and stacked vertically during transportation and / or storage, which overcomes the disadvantages of the prior art.

[0010] This is achieved according to the first aspect of the disclosure, which is optionally independently claimed, by a molded container, in particular a blow-molded container, having the features of claim 1, and preferably by a vertical stacking assembly or stacking system according to the dependent claims thereto, further preferably by a thermoplastic molding method, in particular a blow molding method, for producing a molded container, in particular a blow-molded container according to the disclosure according to the dependent claims thereto, and further preferably by the use of the molded container, in particular a blow-molded container and / or the associated stacking assembly according to the disclosure for accommodating and / or transporting and / or storing medical and / or pharmaceutical preparations and / or for providing preparations (in terms of application technology), in particular providing preparations in dialysis devices, according to the dependent claims thereto. Preferred or advantageous embodiments of the disclosure are derived from the dependent claims, the following description and the drawings.

[0011] Therefore, the core of the present disclosure is to construct a certain number of axial recesses on the container top and a certain number of axial protrusions on the container bottom, and the axial protrusions are coordinated with each other so that when the containers are stacked on each other, the protrusions enter the recesses until they stop in the recesses, so that a distance or free gap is retained between the container bottom of the upper container and the container top of the lower container.

[0012] More specifically, the core of the present disclosure is that, in particular during the manufacture of the container, during (blow) molding, or subsequently by reheating and deformation, a certain number (preferably a plurality) of circumferentially spaced axial depressions / dimples are constructed in the region of the end wall (container top, shoulder section) forming / having the container outlet, wherein the axial depressions / dimples each respectively constitute a load-bearing surface oriented substantially plane-parallel or oblique to the container bottom and a load-bearing surface extending radially (and at least in sections in the circumferential direction). In addition, in particular during the manufacture of the container, during (blow) molding or subsequently by reheating and deformation, a certain number (preferably a plurality) of circumferentially spaced axial protrusions are already formed in the region of the container bottom, wherein the axial protrusions each constitute a load-bearing surface oriented substantially plane-parallel to the load-bearing surface and extending radially (and at least in sections in the circumferential direction), so that when two containers are stacked, the two containers only contact in the axial direction at the load-bearing surface and the load-bearing surface. That is, the recesses in the top area of ​​the container and the protrusions in the bottom area of ​​the container are coordinated with each other in their shape and size, so that when two containers of the aforementioned structural form are stacked on each other, these containers are only placed axially in the area of ​​the load-bearing surface and load-supporting surface (extending horizontally / perpendicularly to the axial axis of the molded container) formed by the recesses and protrusions, while the axially protruding webs between the recesses on the top side and the axially recessed recesses between the protrusions on the bottom side are basically not subjected to axial loads (i.e., theoretically there is no axial contact).

[0013] In other words, the molded container according to the present disclosure, especially the blow molded container made of thermoplastic (such as PET, etc.) is configured to accommodate medicine and / or pharmaceutical preparations and, for example, to be used for vertical stacking during transportation and / or storage. That is, the molded container according to the present disclosure is constructed or shaped so that two identical molded containers can be stacked vertically. The molded container, especially the blow molded container, has a bottom section (container bottom) at one end of the body section and an axially opposed shoulder section (container top) at the other end of the body section. Here, the shoulder section has an (optional) container neck (outlet) in its axial extension. In particular, the container neck can be closed or closed with an optional closure. In the end side bottom surface of the bottom section, the (central) bottom groove is pulled back into the container interior along the axial direction. Here, for the stackability of the stackable molded container, especially the blow molded container (or when stacked into a vertical stacking assembly according to the next second aspect of the present disclosure), the bottom groove is shaped or is configured to accommodate another container neck that is identical to the container neck and is particularly closed without contact. Here, the (radially) outer bottom surface of the bottom groove is formed as a relief-like bottom contour surface, in particular concavely having at least one axially retracted bottom recessed molding segment (recess) and in particular convexly having a bottom load contact molding segment (protrusion) adjacent to the bottom recessed molding segment and protruding axially above the bottom contour surface, so that at least one bottom recessed molding segment is recessed from the supporting surface (load supporting surface) of the molded container, in particular the blow-molded container.

[0014] That is, in particular, the at least one bottom recessed molded segment is formed so as to be shortened relative to the or all bottom load-contacting molded segments with respect to the axial axis. In other words, the at least one bottom recessed molded segment thus divides the support surface of the bottom surface of the molded container, in particular the blow-molded container, which is now (essentially only) formed by the bottom load-contacting molded segment.

[0015] Therefore, the relief-like bottom contour surface as a whole forms a three-dimensional shaped structure pointing to the interior of the container, which provides the following functional and (application) technical advantages:

[0016] On the one hand, with regard to the removal of a (valuable) medical and / or pharmaceutical (especially liquid) preparation from a particularly upright molded container, particularly a blow molded container, when it is used as intended, the residual quantity which can no longer be removed therefrom is advantageously reduced. In other words, the fillable cavity portion close to the bottom surface (which can eventually be reached by, for example, a suction tube of a dialysis device or the like for removing the preparation) is advantageously reduced in favor of the volume occupied by the bottom groove and by the at least one bottom recessed molded section which is additionally drawn back into the container interior.

[0017] On the other hand, the relief-like bottom contour surface associated with the bottom groove (specific "dome geometry") advantageously ensures or improves vertical stackability. Thus, when stacking molded containers, in particular blow-molded containers, according to the disclosure, a form-locking composite is produced. Excessive sliding of the stacked containers in the pharmaceutical / medical field is thus effectively prevented.

[0018] Furthermore, as will be explained in greater detail below, it can be advantageous if the bottom depression profile section can be provided as a (selectively asymmetrical or symmetrical) recess and can therefore be used to accommodate an optional dimensionally stable profile handle, ie a separately produced solid handle element.

[0019] The thermoplastic may preferably be or include polypropylene (PP), polyethylene (PE, such as PE-HD; PE-LD), polyamide (PA), polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), in particular polyethylene terephthalate (PET); or be or include a mixture / blend of thermoplastics of the above-mentioned types. Optionally, the thermoplastic may be partially or completely composed of recycled and / or recyclable materials. Cumulatively or alternatively, the thermoplastic preferably includes biodegradable materials and / or substances, such as polylactic acid (PLA) or essentially consists of biodegradable materials and / or substances. Optionally, the thermoplastic may contain additives / auxiliaries, etc., for example for achieving functional properties in blow molding (e.g. demoulding additives) and / or product applications (e.g. UV protection, nanosilver), etc. Furthermore, preferably, the thermoplastic may be (almost) free of plasticizers. Optionally, it may be preferred that the thermoplastic or the molded container according to the disclosure, in particular the blow-molded container, produced therefrom is transparent (in this case colorless or colored) or opaque (in this case colorless or colored).

[0020] Preferably, alternatively or cumulatively, the at least one bottom recessed molding segment is shape-matched or configured for the stackability of stackable molded containers, especially blow-molded containers (or when stacked into a vertical stacking assembly according to the following second aspect of the present disclosure) so as to be spaced apart from a further shoulder segment (container top) that is the same as the shoulder segment by a gap size without contact, so that only the bottom load-contact molding segment constructs a load-bearing contact surface on the further shoulder segment (container top).

[0021] Optionally, the gap size (particularly the smallest in the axial extension) can be preferably between approximately 0.05 and 20 millimeters, further preferably between approximately 0.5 and 10 millimeters, in particular between approximately 0.5 and 8 millimeters.

[0022] Accordingly, the load contact surface is discontinuously divided / split on the bottom side into individual protruding (convex) bottom load contact profiled segments.

[0023] Preferably, alternatively or cumulatively, the at least one bottom recessed molding segment can (at least partially) extend radially. Here, at least one bottom recessed molding segment can especially extend from the first bottom groove diameter of the opening side of the bottom groove in the transition portion of the bottom surface and / or extend to the periphery of the bottom surface.

[0024] Preferably, alternatively or cumulatively, the container neck can be arranged, in particular centrally / in the axial axis or in the central longitudinal axis, in a shoulder inner region of the shoulder section radially inwardly about the axial axis.

[0025] Preferably, alternatively or cumulatively, the shoulder section outside the container neck can be convexly shaped in relief with at least one shoulder protruding molded segment (joint) between adjacent shoulder load contact molded segments. This is first used to improve the overall rigidity of the molded container, especially the blow molded body / container, and to further reduce the amount of the preparation that can be removed when it is used as specified. Here, the at least one shoulder protruding molded segment (joint) can be shape-fitted or arranged for the stackability of the stackable molded container, especially the blow molded container (or when stacked into a vertical stacking assembly according to the second aspect of the present disclosure below) so that (when stacked) it is complementary to (or with respect to) another bottom concave molded segment that is identical to the at least one bottom concave molded segment in a non-contacting and spaced manner (the bottom concave molded segment), so that the load contact surface is divided into shoulder load contact molded segments on the shoulder side. This is advantageously used for optimization from a static and strength point of view and for improving / widening the (vertical) stackability, and moreover more than two, ie a plurality of stacking layers, of molded containers, in particular blow-molded containers, can be reliably stacked.

[0026] Preferably, alternatively or cumulatively, the load contact surface (load bearing surface) can be configured flat on the shoulder side in the shoulder load contact molding segment (recess) in the cross-sectional plane of the shoulder segment perpendicular to the axial axis. In other words, the shoulder load contact molding segment is form-fitted or arranged for the stackability of stackable molding containers, especially blow molding containers (or when stacked into a vertical stacking assembly according to the second aspect of the present disclosure below) so as to construct a flat bearing surface (shoulder load contact molding segments are almost combined) or to open up the bearing plane. That is, advantageously, another / same (upper) molding container, especially blow molding container (which is vertically stacked on / present on the (first / lower) molding container, especially blow molding container) remains stable on the (first / lower) molding container similarly to when it is directly placed on the floor plane, that is to say not stacked.

[0027] Preferably, alternatively or cumulatively, the at least one shoulder-protruding molded segment is form-fitted or arranged for the stackability of stackable molded containers, in particular blow-molded containers (or when stacked into a vertical stack assembly according to the second aspect of the present disclosure below) so as to be form-lockedly embedded in at least one other bottom-recessed molded segment that is identical to the at least one bottom-recessed molded segment (when stacked). In particular, at least one shoulder-protruding molded segment can be arranged to lock the stacked molded containers, in particular blow-molded containers, from relative rotation (to each other) around an axial axis. That is, these special three-dimensional shapes or molded structures in the shoulder segments and bottom segments of the molded containers, in particular blow-molded containers, which are at least partially / essentially complementary / engaged with each other / mechanically cooperate in the molded composite, cause a form lock. In this regard, this causes additional stabilization by significantly resisting or even preventing the molded composite from twisting.

[0028] In other words, the shoulder surface of the end side of the shoulder section (in the case of vertical stacking: the first / lower molded container, in particular a blow molded container) on the one hand and the bottom surface of the end side of the bottom section (in the case of vertical stacking: the second / first identical / upper molded container, in particular a blow molded container) on the other hand are formed or arranged to cooperate with each other so as to produce a positive lock with each other in the axial direction, the shoulder surface of the end side forming or constructing a three-dimensional molded structure on the shoulder side (in relief) in the form of at least one shoulder protruding molded segment [optionally or in a preferred embodiment, refer to Figures 1 to 7 : by four cross-shaped shoulder protruding molding segments arranged radially around the container neck] and the shoulder load contact molding segment adjacent to this / these [optionally or in a preferred embodiment: four shoulder protruding molding segments, the shoulder protruding molding segments are respectively arranged or formed on the corner edges of the four shoulder sides of the rectangular molded container, especially the blow-molded container, which is basically / relative to the body section], the bottom surface of the end side is (in relief) formed or constructed with a three-dimensional molding structure, which is in the form of the at least one bottom recessed molding segment [optionally or in a preferred embodiment: four shoulder protruding molding segments, the shoulder protruding molding segments are respectively arranged or formed on the corner edges of the four shoulder sides of the rectangular molded container, especially the blow-molded container, which is basically / relative to the body section], the bottom surface of the end side is (in relief) formed or constructed with a three-dimensional molding structure, which is in the form of the at least one bottom recessed molding segment [optionally or in a preferred embodiment In an embodiment: four bottom recessed molding segments, which are respectively arranged or formed between two of the corner edges of the four bottom sides of a (quasi) rectangular parallelepiped molded container, especially a blow-molded container, so as to stand together (when viewed) in a cross arrangement] and are in the form of a bottom load contact molding segment adjacent to this / these [optionally or in a preferred embodiment: four bottom load contact molding segments, which are respectively arranged or formed on the four bottom sides of a (quasi) rectangular parallelepiped molded container, especially a blow-molded container.

[0029] This form-fitting is advantageously used to remove or lock the freedom of rotation about the axial axis or about the longitudinal center axis of the molded container, in particular the blow-molded container. That is, the entirety of the (three-dimensional) molded surface contour on the shoulder side or the molded structural element on the shoulder side (in the axial direction away from the center of the molded container, in particular the blow-molded container) and the (three-dimensional) molded surface contour on the bottom side or the entirety of the molded structural element on the bottom side (in the axial direction away from the center of another / same molded container, in particular the blow-molded container) [or vice versa] form a key-lock-like or plug-in system-like form-fitting. In this case, the axial spacing fit can be formed or arranged in such a way that the load contact surface does not fall in the area of ​​at least one bottom recessed molded segment or a complementary shoulder protruding molded segment. This has the advantage that the load-bearing / weight (load) load is discharged to the outer shell surface of the body section, that is, to the support structure arranged in a tangential manner in the sense of the wall thickness and not to the inner cavity area [in particular the support columnarly discharges to the optional four corners or corner edges].

[0030] In this context, it should be noted that the second aspect disclosed below in relation to the vertical stacking assembly disclosed above should be explained as a precautionary matter, and that a person skilled in the art understands that the features disclosed in relation to the first aspect of the molded container, in particular the blow molded container, according to the present disclosure and related to form fit can be verified individually or by themselves on the molded container. In this regard, these claimed features can be understood or verified either virtually (e.g. with the aid of a structural design drawing, a CAD-3D model) or actually (e.g. with the aid of a cut of the molded container, in particular the blow molded body / container, along a section plane falling in the body section and the axially swapped insertion of the bottom-side half on / in the shoulder-side half).

[0031] Preferably, alternatively or cumulatively, the bottom section can be shaped as a polyhedron with associated corners in a cross-sectional plane perpendicular to the axial axis. Some or all corners can have bottom load-contacting molded sections, in particular in proportion to a uniform and / or symmetrical load distribution. This is advantageous for a balanced statics / rigidity of the molded container, in particular the blow molded body / container, and also for generally favorable support / handling properties.

[0032] Preferably, alternatively or cumulatively, the bottom section can be rectangularly shaped with four corners in a cross-sectional plane perpendicular to the axial axis. In this case, some of the four corners, in particular all of the corners, have a bottom load-contacting shaped segment. In this case, in particular four optional shoulder-projecting shaped segments can be arranged cross-shaped around the container neck and radially relative to the container neck, in particular opening into the container neck (with a continuously extending contour line) [see reference to the attached Figures 1 to 7The above preferred embodiment]. That is, by the described cross-shaped or "super-cross-shaped" arrangement of the described molding structural elements, two (identical) specially shaped novel contact surfaces of the molding containers, especially blow-molded containers, according to the present disclosure are advantageously obtained. Therefore, in the case of vertical stacking, these molding containers only contact each other at the four outer (particularly stable) corners, namely at the shoulder section (shoulder load contact molding section) of the lower molding container, especially the lower blow-molded container, or at the bottom section (bottom load contact molding section) of the upper molding container, especially the upper blow-molded container.

[0033] Preferably, alternatively or cumulatively, the bottom section and / or the shoulder section (substantially, viewed from a bottom view or a top view) can be shaped mirror-symmetrically, in particular point-symmetrically. Here, the mirror axis can in particular include a diameter line / section.

[0034] Preferably, alternatively or cumulatively (depending on the aspects to be protected independently if necessary), on the load contact surface, at least one of the bottom load contact profiled segments has a bottom profiled structural element, in particular in the form of a radial groove, formed radially on the bottom side, in particular (at least partially), which is concave or contoured to the container interior in the direction of the axial axis; and a shoulder profiled structural element, in particular (at least partially) radially correspondingly formed opposite / complementary to the bottom profiled structural element, i.e. correspondingly contoured convexly, in particular in the form of a radial longitudinal bulge, is formed on the shoulder side. In particular, the radial shaping or radial orientation can form a profile of the bottom profiled structural element and the complementary associated / corresponding shoulder profiled structural element, which extends essentially radially from or to the central axial axis of the molded container. Preferably, alternatively or cumulatively, the bottom profiled structural element and the complementary associated / corresponding shoulder profiled structural element can extend radially from the bottom groove. The above-mentioned form-locking serves to additionally prevent rotation and also to increase the stability of the vertical stack assembly against uneven weight distribution, slipping, tipping or overturning. In particular, at least one, in particular a pair of (at least partially radial) bottom profile elements can respectively match (or form-fit) with at least one, in particular a pair of (at least partially radial) shoulder profile elements, respectively / for each corner side.

[0035] That is, in the sense of improving the stability of the vertical stacking assembly, the (at least partially radial) bottom molding structural element can be said to engage / press / grasp into the matching radial (at least partially radial) shoulder molding structural element (at the bottom) (from above) so as to abut against each other in a form-locking manner. This advantageously causes a (vertical) locking and thus further fixation of the tower-shaped stacking assembly to prevent sliding, twisting, distortion, overturning, etc. of the (blow) molded container. In other words, the above-mentioned aspect further advantageously improves the balance and stability of the (vertical) stacking assembly. Therefore, the operational safety in clinical procedures is significantly improved or the risk of accidents is reduced for medical users. This also reduces the risk of potential storage and / or transportation damage of the molded container according to the present disclosure filled with valuable medical and / or pharmaceutical preparations.

[0036] In addition, with respect to the thermoplastic forming method, in particular the blow molding method, for manufacturing the molded container, in particular the blow molded container according to the present disclosure, additional advantages of the above-mentioned features are obtained. In this regard, due to the (at least partially) radial direction, production technology advantages are also shown, which arise from the molding tool from the perspective of good demouldability. Therefore, the molding tool can have a single molding tool punch in the area of ​​the bottom section or the shoulder section, so as to easily demould or eject the manufactured molded container. Here, the individual molding tool punches can be separated along radial lines corresponding to the extension of the (at least partially radial) bottom molding structural element or the shoulder molding structural element. Exemplarily, the individual molding tool punches can describe a rounded corner segment. In this way, the individual molding tool punches can be moved individually with a radial movement component (that is, superimposed with an axial movement component) for demoulding or ejection, which is advantageously easy and therefore with a high number of cycles. In contrast, tangentially and / or annularly extending profiles with body edges which are not designed to be open, cup-shaped, or dome-shaped like bottom grooves, but are, for example, groove-shaped, present technical problems with regard to adhesion to the forming tool, shrinkage, etc. These can impede production and lead to frequent downtime of the forming machine or a high proportion of rejects.

[0037] Preferably, alternatively (or opposite to the above features) or cumulatively, a bottom molding structural element (e.g., longitudinal ridge) convexly contoured in the direction of the axial axis may be formed on the load contact surface in at least one bottom load contact molding segment on the bottom side; and a shoulder molding structural element (e.g., groove, longitudinal groove) opposite / complementary to the bottom molding structural element, that is, correspondingly concavely contoured, may be formed on the shoulder side. In particular, the shoulder molding structural element may be form-fitted or arranged for the stackability of stackable molded containers, in particular blow molded containers (or when stacked into a vertical stack assembly according to the second aspect of the present disclosure below) so as to be form-fittedly abutted on another bottom molding structural element identical to the bottom molding structural element (or so as to be form-fittingly abutted on the corresponding bottom molding structural element of the other molded container, in particular blow molded container, when stacked). In particular, the radial shaping or radial orientation can form a profile of the bottom profiled structural element and the complementary associated / corresponding shoulder profiled structural element, which extends essentially radially from or toward the central axial axis of the molded container. Preferably, alternatively or cumulatively, the bottom profiled structural element and the complementary associated / corresponding shoulder profiled structural element extend radially from the bottom groove. In contrast, this form-fitting also serves the advantages described above.

[0038] It should be noted that a person skilled in the art will appreciate that it is conceivable to construct a profiled portion of a radial bottom profiled structural element that is convex and concave (at least partially) contoured and a complementary corresponding / corresponding concave and convex (at least partially) contoured radial shoulder profiled structural element. In particular, the profiled portion can be a transition from concave to convex and / or alternating.

[0039] In any case, it is understood by a person skilled in the art that this (if necessary independently claimed) aspect of the (at least partially) radially extending bottom profile structural element and the complementary associated / corresponding shoulder profile structural element does not necessarily have to be associated with the presence of a container neck with an associated / corresponding bottom groove (upper profile container) for vertically accommodating the container neck (lower profile container) in the case of vertical stacking. On the contrary, it is also conceivable to omit the bottom groove for no container neck to be present in the shoulder section, but only for an outlet opening (e.g. a hole) to be inserted into the shoulder section, and / or for the container neck to be sunken or to be flexibly sunk in the shoulder section.

[0040] From this possibly independently claimed aspect, the following subject matter results:

[0041] A molded container, in particular a blow molded container, made of thermoplastic (or a molded container produced by a thermoplastic molding process) for containing medical and / or pharmaceutical preparations, wherein the molded container is shaped and / or form-fitted and / or arranged so that two (substantially) identical molded containers can be stacked vertically for transportation and / or storage, the molded container having: a bottom section at one end of a body section with a bottom surface at the end side of the bottom section; and a shoulder section at the other axially opposite end of the body section. Here, the bottom surface (in particular outside the (optional) bottom groove for stackability (and if necessary to accommodate an optional container neck on the shoulder section)) is formed as a relief-like bottom contour surface, which has at least one axially recessed bottom concave molded section and a bottom load-contacting molded section adjacent to the bottom concave molded section and axially protruding above the bottom concave molded section, so that the at least one bottom concave molded section is recessed from the support surface of the blow molded container. Here, the at least one bottom depression molded segment is form-fitted or arranged for the stackability of the stackable blow-molded containers so as to be spaced apart from a further shoulder segment having the same gap size as the shoulder segment without contact, so that only the bottom load-contacting molded segment forms a load-bearing load-contacting surface on the further shoulder segment, wherein on the load-contacting surface in at least one of the bottom load-contacting molded segments:

[0042] - radial bottom-shaped structural elements correspondingly formed on the bottom side, in particular concavely formed in the form of radial grooves, which are contoured concavely in the direction of the axial axis (Z) or in the container interior or optionally convexly; and

[0043] On the shoulder side, a radial shoulder profile element is correspondingly convexly formed, in particular in the form of a radial longitudinal elevation, which is contoured oppositely or complementary to the base profile element.

[0044] In this case, the radial shoulder profile elements can be formed in particular for the vertical stackability of the stackable blow-molded containers or can be arranged so as to bear in a form-fitting manner against further radial bottom profile elements which are identical to the bottom profile elements.

[0045] Preferably, alternatively or cumulatively, the (optional) bottom groove can be preferably cup-shaped in the bottom groove depth, tapering from a first bottom groove diameter on the opening side to a second bottom groove diameter on the base side of the inner bottom groove base. Here, the bottom groove can have at least one bottom groove shoulder, in particular, on a third (or additional other) bottom groove diameter that shrinks in a step-like manner. This is advantageously used to reinforce the bottom groove. In addition, both the tapering and the (optional) bottom groove shoulder lead to an advantageous further reduction of the residual amount of (valuable) medical and / or pharmaceutical (especially liquid) preparations that can no longer be removed from the molding container, in particular the blow molding container. It is understood by those skilled in the art that the specific three-dimensional contour or molding structure of the bottom groove, as exemplarily described according to the preferred embodiment shown in the drawings, is not the main point of the present disclosure, but equivalent contours or molding structures are also conceivable. For example, the bottom groove can be configured to be rectangular, pyramidal, etc. It can still be seen that there is an interaction with respect to the overall shape stability / mechanical properties / load statics, and possibly a synergistic interaction or optimum range depending on the design / shaping of the bottom groove and the design / shaping of the adjacent, in particular surrounding, relief-like bottom contour surface.

[0046] Preferably, alternatively or cumulatively, a molded container, in particular a blow-molded container, having / defining a radial first wall thickness in a bottom section, a radial second wall thickness in a body section and a radial third wall thickness in a shoulder section can be formed from a thermoplastic plastic / material so that the first, second and / or third wall thickness: (a) is a maximum of about 1.5 mm, further preferably between 0.05 mm and 1.2 mm, in particular between 0.15 mm and 1.0 mm; and / or (b) has a relative dispersion width of at most + / -150%, in particular at most + / -50% around its respective average value; and / or (c) has a relative dispersion width of at most + / -150%, in particular at most + / -50% around its total average value calculated from the first, second and third wall thicknesses.

[0047] Optionally, the molded container, in particular the blow-molded container, can be blow-molded from a preform (optionally with a finished container neck) which has a fourth wall thickness which is thicker than the first, second and / or third wall thickness.

[0048] Preferably, alternatively or cumulatively, the thermoplastic can be suitable for directly accommodating and subsequently storing the medical and / or pharmaceutical preparation on the production side, in particular for (long-term) inertness with respect to the preparation, further preferably, additionally selected or modified in order to achieve specific optimal flow properties in the thermoplastic state in order to construct the above-mentioned features with regard to the wall thickness (distribution) of the molded container, in particular the blow-molded container according to the disclosure. Thus, the material consumption and the mechanical long-term stability / statics required for the product are optimized as mutually opposing influencing variables.

[0049] Preferably, alternatively or cumulatively, the molded container, in particular the blow molded container, can have at least one rib or rib (molding) structure extending at least in sections around the body section, in particular substantially transversely to the axial axis (that is, almost "horizontally"), in particular a plurality of ribs or rib moldings extending at least partially parallel to each other. Here, at least one rib or rib molding / row can be optionally constructed or shaped with a V-shaped course, in particular for at least one (in particular all) corresponding side / cover surfaces of the body section (that is, from a side view of the (blow) molded body / container). In this case, it is further preferred that the apex of the V, in particular arranged in the middle, selectively points to the shoulder section (that is, upwards) or in an inverted (that is, inverted V-shape) to the bottom section. The person skilled in the art understands that variations in shape are conceivable, such as a double V-shape, a combination of a first row of V-shapes above or below a second row of inverted V-shapes, a corrugated shape, etc.

[0050] At least one optionally provided (reinforcement) rib (or a plurality of ribs or rib profiles) is formed between a pair of adjacent depressions / rib grooves / grooves. Here, the ribs or depressions / rib grooves are advantageously used to strengthen / optimize the static load-bearing properties and also to improve the manual handling properties, especially with respect to the filled (blow) molded container. That is, the ribs act as body molding structural elements. Therefore, after the (blow) molded body / container is filled with the formulation, the rib (molding) structure advantageously increases the stability. Therefore, possible deformation / bulging of the (blow) molded body / container is prevented, which ensures or improves its shape stability, especially considering the desired vertical stackability, storage stability under the main conditions such as temperature, mechanical stress caused by transportation, etc. In particular, in the case of an ideal reduction in wall thickness, as long as people want to reduce the use of thermoplastics for the (blow) molded body / container to a large extent, the (optional, i.e., in principle, can be omitted in the case of sufficient wall thickness) ribs are proven to be particularly advantageous. Rib (molded) structures are particularly useful when molded containers, in particular blow-molded containers, are stacked vertically in multiple (ie more than two) layers / have multiple layers, as long as the correspondingly multiplied supporting forces / weight forces generated can be better absorbed and distributed (down to the bottom layer).

[0051] Here, the rib is formed as a convex protrusion or convex arch which is substantially uniform (preferably continuous) and circumferentially relative to the adjacent depressions / rib grooves, in particular (substantially or with respect to the primary extension direction) circumferentially to the axial axis (i.e. horizontally). For example, the rib can have a (particularly corresponding) rib cross section which is designed to be wavy, prismatic, rectangular or circular, rounded, elliptical or in accordance with a free contour. Optionally, some or all of the (particularly otherwise circumferential) ribs and / or depressions / rib grooves can be interrupted by flat areas, for example in order to provide a flat surface which is provided for (sticking) labels and / or for attaching a film strip-shaped handle (according to the optionally independently claimed aspects) and / or for manual or robot gripping. Optionally or selectively, the wall thickness in the region of the ribs and / or depressions / grooves can differ significantly (for example by a relative deviation of more than 10%) from the other (first, second and / or third) wall thickness of the molded container, in particular the blow molded container. The person skilled in the art understands that it may be selectively meaningful to determine the wall thickness(es) in the region of the ribs and / or depressions / rib grooves as a separate dimension or to adjust the wall thickness(es) in the blow molding (manufacturing method). Alternatively, it may be desirable or advantageous to determine the wall thickness(es) in the region of the ribs and / or depressions / rib grooves as a dimension that is substantially uniform with the other (first, second and / or third) wall thicknesses of the molded container, in particular the blow molded container, or to adjust the wall thickness(es) uniformly with the other wall thickness(es) in the (blow) molding (manufacturing) method.

[0052] Preferably, alternatively or cumulatively, the molded container, in particular the blow molded container, can be provided with at least one label (in particular a marking, for example a self-adhesive film label surface or the like) on at least one cover section and / or on a (visible) side, in particular on a body section. In this case, the label can optionally be applied to the ribbed profile, wherein it is further preferred that the adhesive means provided for labeling leave the rib groove free. The label is used in a technically simple manner for (legally required) product marking and user information.

[0053] Preferably, alternatively or cumulatively, the molded container, in particular the blow molded container, is closed with a closure, in particular a screw-on (cap) closure (with an internal thread). This is advantageous for the simple closing of the (blow) molded container filled with the preparation in terms of production technology. Here, the closure (in particular, produced separately, for example by injection molding, available) can be simply changed in terms of production technology and equipped with specific functions. For example, the closure can also optionally include additional elements, such as a flip opening and / or a piercing membrane. This is advantageous for the convenient and / or (as far as possible) aseptic removal of the preparation.

[0054] Preferably, alternatively or cumulatively (depending on the aspects to be protected independently if necessary), a shape-stable molded handle can be arranged on the container neck. In particular, the (shape-stable) can be made of a thermoplastic material (optionally, for example, different or similar / changed with respect to the so-called melt flow index, or identical to the thermoplastic plastic of the molded container, in particular the blow-molded container), in particular injection molded. In particular, the molded handle can be fixedly, in particular non-detachably arranged on the container neck, for example, by shrinking or by means of a cover sleeve device to fasten / fix. In particular, the molded handle can have a proximal molded handle annular section (in terms of the container neck or the molded container, in particular the blow-molded container) so as to be arranged on the container neck (in particular non-detachably) by means of the molded handle annular section. In this case, the molded handle annular section is (optionally) configured with a barb-shaped element on the inside. The barb-shaped element is arranged to fix the molded handle on the container neck in a relatively rotationally fixed manner. This advantageously prevents separation during manual carrying.

[0055] In addition, the molded handle (at its opposite end) has a molded handle holding section distal to the molded handle, which (starting from the molded handle annular section) extends essentially radially from the container neck (away). In particular, the molded handle holding section can be designed in a T-shape or a U-shape. Accordingly, the molded handle can also be referred to as a T-handle or a U-handle. By (optionally) providing a handle element, such as a molded handle (and / or a carrying handle described below, depending on the aspects that may be independently claimed for protection), from a separate carrier material, the flexibility when handling or using the (blow) molded container according to the present disclosure can be further improved. In addition, the production is simplified by prefabricating the separate handle element. In this regard, depending on the specific circumstances (but not limited to this), it is advantageous in terms of production technology (in terms of investment savings and so-called "economy of scale") to obtain the separate handle element as a purchased part from a supplier specializing in handles.

[0056] Here, the at least one bottom recessed molded section can be form-fitted or arranged for the stackability of stackable molded containers, in particular blow molded containers (or when stacked to form a vertical stack assembly according to the second aspect of the present disclosure below) so as to be contact-freely spaced apart by at least one minimum gap dimension from a further shoulder section identical to the shoulder section. Here, the minimum gap dimension can in particular exceed the maximum axial molded handle outer dimension of the distal molded handle holding section. This is advantageous for accommodating the molded handle without adversely affecting or even interfering with other (vertical) stacking properties.

[0057] Preferably, alternatively or cumulatively (depending on the aspects to be protected independently if necessary), the preferably sheet-shaped carrying handle can be applied, in particular glued (for example by a self-adhesive layer, by hot melting) or attached (for example spot welding) to the molded container, in particular the blow-molded container. In this case, the carrying handle can be designed in particular as a film-strip-shaped carrying handle (or a sheet-shaped supporting handle; formed by a flat structure). As an alternative to this, the carrying handle can be designed from a rolled, folded, etc. material. In this case, the carrying handle is applied, in particular fixedly connected / joined / adhesive, so as to form a carrying handle middle section extending arcuately between the carrying handle ends and axially on the other side of the shoulder section. In this case, the carrying handle can be applied with its two opposite carrying handle ends tangentially to two corresponding connection points of two opposite outer covers of the molded container, in particular the blow-molded container, in particular the body section. According to the above-described embodiment of the handle element in the variant of the carrying handle, that is to say in the form of a film, material can be saved in an advantageous manner. Furthermore, in the case of a carrying handle, it is technically advantageous that it can be installed very flexibly in terms of time, ie at any time along the production or logistics value chain.

[0058] In this regard, it should be noted that the above features relating to the carrying handle (cf. the attached drawings relating to the preferred embodiment with the carrying handle) Fig. 9 and 10 ) for the subject matter claimed independently if necessary (in particular also for any container for any content, i.e. not necessarily restricted to blow-molded production and / or alternatively or cumulatively preferred features of materials made of thermoplastic material and / or a specific bottom / shoulder profile). In this regard, this feature is directed to a solution with a technically independent purpose and the advantages achieved independently of the subject matter currently claimed according to claim 1 (specific bottom-side molding structure, in short: bottom recessed molding segment, etc.):

[0059] A container, in particular a molded container, in particular a blow molded container (according to the above-mentioned independent subject) made of thermoplastic, in particular PET, is particularly provided for accommodating medical and / or pharmaceutical preparations and is particularly provided for vertical stacking during transportation and / or storage. The molded container, in particular a blow molded container, has a bottom section at one end of a body section and an axially opposed shoulder section at the other end of the body section. Here (optionally) the shoulder section can have a container neck in its axial extension. In particular, the container neck can be closed or closed with an (optional) closure. In the end side bottom surface of the bottom section, the bottom groove can be (optionally) pulled back axially into the container interior. Here, (optionally), for the stackability of the stackable molded container, in particular the blow molded container (or when stacked into a vertical stacking assembly according to the following second aspect of the present disclosure), the bottom groove can be form-fitted or provided for contactlessly accommodating another container neck that is identical to the container neck and is particularly closed. Here, (subjectively) a sheet-like, in particular film-strip-like, carrying handle (optionally in addition to a dimensionally stable molded handle) is attached, in particular glued or joined, to the (optionally stackable) molded container, in particular blow-molded container, in order to form a central section of the carrying handle extending arcuately between the carrying handle ends and axially on the other side of the shoulder section. Here, the carrying handle is attached with its two opposite carrying handle ends tangentially to two associated connection points of two opposite outer covering surfaces of the (blow-molded) container, in particular the body section. This arrangement advantageously has the effect that the two carrying handle ends (that is to say, for example, respectively opposite sides of the adhesive strip) resist possible unintentional removal by the user and that the carrying handle is held in place overall.

[0060] The sheet-like material or the flat structure of the sheet-like, especially film-strip-like carrying handle can be, in particular, a (especially multi-layered) plastic film and / or paper laminated with a plastic film and / or a fiber-reinforced composite material. In addition, the use of a combination of different (plastic) materials can be preferred. Further preferably, the sheet-like material can be initially arranged in a folded manner so that it is not unfolded until it is used into its final display shape. Further preferably, the sheet-like material or the flat structure can include an elastic material and / or a shape memory material, in particular an elastic material and / or a shape memory material, whereby the handling of the molded container, in particular a blow molded body / container according to the present disclosure is further simplified or improved in this preferred embodiment. In particular, the carrying handle can be attached or fastened to the molded container, in particular a blow molded container, in such a way that the carrying handle rests on the molded container, in particular a blow molded container, in a metastable state and protrudes from the molded container, in particular a blow molded container, in a stable state. Additionally / optionally, the film handle can be constructed using a soft foam-like material (or another such layer); this leads to an increase in the carrying comfort of the user due to the depolarization. Preferred length and width dimensions of the carrying handle, in particular for an exemplary molded container, in particular a blow molded container, with a nominal filling volume of 4.7 liters, can preferably be approximately 160 mm to 380 mm for the carrying handle width and approximately 200 mm to 300 mm for the carrying handle length.

[0061] Preferably, alternatively or cumulatively, the handle center section can be printed or printed, in particular, with special usage information and / or article identification. This is used for (legally required) product marking and user information in a technically simple manner.

[0062] Preferably, alternatively or cumulatively (depending on the aspects to be protected independently if necessary), the carrying handle can be arranged eccentrically relative to the two connection points, respectively. In particular, the carrying handle can be arranged offset in the transverse direction from a perpendicular point falling in the cross-sectional plane of the axial axis.

[0063] Preferably, alternatively or cumulatively (depending on the aspects to be protected independently if necessary), the carrying handle can be tilted at the two connection points, respectively, obliquely to the axial axis. In this case, the tilting angle of the carrying handle, which can be defined in particular between the axial axis (or the vertical line) and the longitudinal extension of the carrying handle, is between 10 and 50 degrees, preferably between 30 and 40 degrees, and further preferably between 25 and 35 degrees [reference Fig.10Note: The angles drawn with the reference numeral "W" with respect to the horizontal line relate to angles complementary to a right angle or 90°, starting from the angle of the carrying handle inclination (carrying handle inclination supplementary angle with the reference numeral "W"); thus, they are in the range of angles between 80 and 40 degrees, preferably between 60 and 50 degrees, and further preferably between 65 and 55 degrees]. In addition to very good operability of the molded containers, in particular blow-molded containers, this also results in the following further advantages: improved stackability (as long as the carrying handles do not come into contact with or interfere with the contact surfaces during vertical stacking); in addition, the possibility of mounting the molded containers, in particular blow-molded containers, for example, by means of a suspension device for a dialysis device; in addition, the discharge / removal of residual amounts of the contained (liquid) agent is further improved, i.e., the non-removable residual amount is minimized, for example, by means of the suction connection pipe / spout of the dialysis device; and in addition, the manual carrying properties are improved (more favorable position of the center of gravity, the hand of the carrier does not come into contact with the container neck / (screw) closure). In particular, the geometry selected in this way in the arrangement of the carrying handle, i.e. with an eccentric arrangement and / or with an inclined carrying handle inclination angle, is a significant improvement over previous solutions (i.e. centrally arranged and linearly / axially extending) (as known in the field of multi-packaging or multiple packaging of beverage bottles, but arranged on an outer film shrink secondary packaging that holds a plurality of beverage bottles together, i.e. not directly on the individual beverage bottles). The load-bearing properties are thus significantly improved. Furthermore, contact between the user's hand and the rest of the molded container, in particular the blow-molded container, is advantageously avoided. This advantageously reduces the risk of injury associated with this. Furthermore, in the case of an oblique inclination, the carrying handle can be designed to be significantly shorter than in the case of a vertical arrangement (carrying handle inclination angle of 90°) in order to prevent contact between the user's fingers when using the closure, which in turn leads to an advantageous material saving in terms of the film strip cut to length for the carrying handle, etc. A person skilled in the art will appreciate that, as an alternative to the preferred / particularly advantageous oblique and slanted arrangement described above, it is either conceivable / implementable in principle, depending on the individual circumstances (e.g. depending on a possibly existing carrying handle labeling machine park), to maintain an axial and central arrangement of the carrying handle so that the middle section of the carrying handle is located directly above the container neck or the closure (corresponding to a carrying handle slant angle of 90°, so-called “inverted arrangement”).

[0064] The above-mentioned inclined angle of the handle in the angle range between 10 and 50 degrees, preferably between 30 and 40 degrees, and more preferably between 25 and 35 degrees [defined respectively between the axial axis (or vertical line) and the longitudinal extension line of the handle], provides a user with an advantageous alternative, namely, two (general) containers / bottles, in particular molded containers according to the present disclosure, in particular blow-molded containers, can be carried simultaneously with one hand. Here, the handle or the middle section of the handle is respectively surrounded by the user's hand. The (vertically / axially extending) lateral outer cover surfaces of the two containers / cans, in particular molded containers according to the present disclosure, in particular blow-molded containers, directly contact each other here (that is, when grasped in pairs) and stabilize the carrying assembly. The mentioned preferred angle range generates a physical force or weight vector component, which presses / compresses the cans, in particular molded containers according to the present disclosure, in particular blow-molded containers, against each other at the mentioned abutting outer cover surfaces. As a result, the molded composite of the two cans is further stabilized in an advantageous manner, for example, to prevent sliding and displacement.

[0065] A second aspect of the present disclosure (independently claimed if necessary) relates to a (particularly vertical) stacking assembly or stacking system, which comprises at least two, preferably at least three, in particular at least four, (particularly vertically or along an axial axis) stacked (identical and / or substantially similar) molded containers, in particular blow-molded containers, according to the present disclosure. In particular, the (combined) stacking assembly can be arranged in a stacked manner in the vertical direction as well as in the horizontal direction. This is particularly used for optimal space utilization in storage and transportation areas. As long as the stacking assembly / stacking system comprises (identical and / or substantially similar) molded containers, in particular blow-molded containers, of the module / assembly type according to the present disclosure, it is explicitly pointed out that the same features and advantages as the first aspect of the present disclosure are produced.

[0066] The outer dimensions of the (blow) molded containers, in particular the body sections, can preferably be designed such that (in particular with regard to vertical repeating components) a plurality of units of blow molded containers produce a form-fitting (stacked) complex (in particular without molded containers, in particular blow molded containers protruding) on ​​a transport pallet (in particular EU transport pallet, standardized sea pallet / container pallet). This has the advantage that no or only minimally reduced free space, for example the volume of a transport container, remains unused. This means that optimal utilization of the available bottom surface of a transport pallet used in accordance with standards is achieved. In particular, the following dimensions of the molded container, in particular the blow-molded container, are particularly preferred, for example when the nominal filling volume is approximately 4.7 to 4.8 liters: a) for EU transport pallets, 148 mm×158×295 mm (molded container width×molded container depth×molded container height); or: a) for standardized sea / container pallets, 140 mm×150×320 mm (molded container width×molded container depth×molded container height); however, the above-mentioned filling volume of approximately 4.8 liters should not be regarded as restrictive; therefore, within the scope of the present disclosure, further increased or reduced filling volumes are also claimed or possible, in particular the filling volume is obtained based on the matching of the usage characteristics of the medical / pharmaceutical preparation.

[0067] In particular, according to current trends, it is also conceivable, for example, to further reduce the filling volume, further preferably to about 3.8 to about 4.2 liters. In this regard, further advantages are obtained, especially against the background of improving the environmental balance, reducing manufacturing costs and / or based on adapting the filling volume to obtain shorter dialysis times and / or lower dialysate flow rates. In order to achieve the above-mentioned optimization goals in terms of the optimal packaging specifications on the transport pallet, for a molded container with an (optionally) reduced filling volume of, for example, about 3.8 to / or about 4.2 liters, the following dimensions (molded container width×molded container depth×molded container height) may be preferred:

[0068] a) a molded container with a fill volume of about 3.8 liters: 148 mm x 158 mm x 243 mm; or

[0069] b) Molded container with a fill volume of approximately 4.2 liters: 148 mm x 158 mm x 261 mm.

[0070] Alternatively or cumulatively, multiple filling volumes are proposed to allow double or multiple use of (e.g. clinically common or commercially common) consumable units of medical / pharmaceutical preparations, in particular dialysis preparations / solutions (e.g. approximately 7.6 to 8.4 or approximately 9.4 to 9.6 or 10.0 liters of content, etc.).

[0071] Alternatively, the molded containers, in particular the blow molded bodies / containers, can be packed in cartons or other secondary outer packaging from the factory. In this regard, the advantages of vertical stackability do not occur during transport itself, but rather during the intended use of the preparation and / or during the preparation, for example in the clinical process / material flow. For example, additional loading space is advantageously created, which saves corresponding storage capacity.

[0072] In particular, the size / dimensions / form fit of molded containers, in particular blow-molded containers, can be optimized and designed in terms of application technology so that the following influencing variables or technical aspects are taken into account cumulatively or alternatively. In particular (but not restrictively), all influencing variables can be combined in a particularly preferred embodiment (see the drawings) and converted in a particularly advantageous manner:

[0073] - a nominal filling volume, corresponding to the typical content of the medicinal / pharmaceutical preparation for its intended use (e.g. a dialysis liquid or a dialysis solid concentrate for performing a dialysis treatment);

[0074] -Vertical stackability for transport, storage, etc.;

[0075] - possibilities for additional stability, in particular when installing / connecting to an apparatus / machine unit which is provided / operable for the intended use of a medical / pharmaceutical preparation (e.g. a dialysis machine);

[0076] - possibilities for connection, in particular to the dimensions / size of a removal / suction device of an apparatus / machine unit (eg a dialysis device);

[0077] - the dimensions / size of the bottom section relative to a designated placement surface of the device / machine unit (eg the base of a dialysis apparatus);

[0078] - A bottom groove ("dome geometry") for minimizing the residual amount of medical / pharmaceutical preparation remaining in the container after completion of the performed treatment (eg dialysis treatment).

[0079] A third aspect of the present disclosure (independently claimed if necessary) relates to a thermoplastic forming method, in particular a blow molding method, for producing a molded container, in particular a blow molded container, according to the present disclosure according to the first aspect, comprising the steps of:

[0080] - thermoplastically constructing or shaping, preferably injection molding, in particular blow molding, a thermoplastic plastic, preferably PET, which is suitable and / or inert with respect to medical and / or pharmaceutical preparations, in a thermoplastic flow state in a separable molding tool, preferably an injection molding tool, in particular a blow molding tool, which is constructed and arranged complementary to the molding container, in particular the blow molding container, wherein in particular (in the case of a blow molding method) a thermoplastic plastic material, preferably PET, can be provided in the form of a preform having the container neck; and

[0081] - Cooling the thermoplastically constructed or shaped molded container, in particular a blow-molded blow-molded container, in order to remove / shape it in its (in particular sufficiently dimensionally stable) solidified state.

[0082] An optional step, which may in particular be at least partially superimposed in time on at least one of the above steps, involves filling the molded container, in particular the blow-molded container, with the medical and / or pharmaceutical preparation. A further optional step involves closing the filled molded container, in particular the blow-molded container, preferably in a molding tool, in particular a blow-molding tool, or in a molding machine, in particular a blow-molding machine, which operates the molding tool, in particular the blow-molding tool.

[0083] Blow molding refers to a method for manufacturing hollow bodies from thermoplastics, especially injection molding, stretching and blow molding methods. Here, blow molding can be carried out based on extrusion blow molding and / or stretch blow molding. In blow molding, a certain amount or volume or mass unit of thermoplastic is basically preset, especially in the form of a preform (optionally prefabricated separately as an intermediate product), and the thermoplastic is made to enter its thermoplastic flow state (by means of heating and / or extrusion kneading). Then it is applied with internal pressure through the blow nozzle of the blow molding machine and is thereby pressed onto the molding contour of the blow molding tool to form the desired molded body shape. Here, it is known to use a blow molding tool punch that can be moved separately to realize a complex molding structure with, for example, an undercut. In addition, the blow molding method can be optionally implemented as a so-called blow filling and sealing method (that is, including filling and sealing in the blow molding tool in the container neck area) and / or implemented as a so-called hot filling method. Patent document US5,411,699, which is hereby expressly incorporated by reference as a component of the present disclosure, discloses a blow molding method for thermoplastic blow molding or for producing blow molded (hollow) bodies, such as PET beverage bottles, which is operated in a blow molding machine, wherein a separately prefabricated (injection molded) approximately test tube-shaped preform with an external thread integrally formed on the opening is inserted into a divisible blow mold and blown (molded) in the hot plastic state into a blow molded (hollow) body. In this case, the container neck preferably retains its original size and shape, that is to say the preform, and is thus not changed during the stretch blow molding process. In addition, a subsequent hot filling step is disclosed.

[0084] Blow molding as a (preferred) thermoplastic process for producing molded containers according to the present disclosure, especially blow molded bodies / containers for medical / pharmaceutical preparations based on thermoplastic plastics / materials (especially but not limited to polyethylene terephthalate / PET) generally offers the advantage of an increased cycle number compared to previous injection molding processes.

[0085] Blow molding has the additional advantage of reduced material consumption due to the significantly reduced wall thickness (no flow resistance in the flow channel that limits the minimum wall thickness in the injection molding process), which leads to a significant reduction in production costs and a lower environmental load. In particular, in the thermoplastic forming or forming according to the present disclosure, in particular blow molding, the average and / or nominal wall thickness can be in the range of up to about 1.5 mm, more preferably between 0.05 mm and 1.2 mm, in particular between 0.15 mm and 1.0 mm.

[0086] In contrast, it is known that conventional wall thicknesses of molded containers in large-scale (standard) injection molding methods range from about 0.5 mm to 0.8 mm to about 3 mm and more. Furthermore, large-scale (standard) injection molding methods are described in the prior art, which, for example, can achieve flow path to wall thickness ratios of up to 60. This means that injection molding methods are more suitable for producing solid (filled) components, such as automobile bumpers or transport pallets, and less suitable for producing hollow (unfilled) components, such as (especially thin-walled) containers.

[0087] However, thinner wall thicknesses, that is to say in the range of less than about 0.5 mm up to about 0.3 mm, can be achieved as required or separately by (possibly technically more complex and therefore more cost-intensive) special injection molding methods. In particular, such special injection molding methods are so-called thin-wall injection molding (especially based on special molding tool coatings and / or special grades of thermoplastics / materials optimized in terms of curing rheology) and / or so-called high-pressure injection molding (for example in the range of injection molding pressures above 1000 bar, especially above 2000 bar or more) to achieve the thinner wall thicknesses mentioned.

[0088] In other words, preferably, the molded container according to the present disclosure is constructed / molded as a blow molded container or is constructed / molded by means of blow molding, but this should not be interpreted as restrictive. In this regard, it is conceivable that the injection molding method (standard injection molding or special injection molding) is selected as required in terms of weighing all viewpoints for product design (e.g. long-term storage stability and / or high transport stability of the molded container as primary packaging and / or application technology) and / or for product reception (e.g. the investment in the machine park that has historically been present at the production site must be kept low, etc.).

[0089] Thermoplastic construction or shaping, preferably injection molding, in particular blow molding, further has the advantage that the molded container, in particular blow molded body / container according to the present disclosure can adopt its specific three-dimensional complex form / shape in a manufacturing-technically efficient manner, such as the currently main specific bottom geometry (in the form of a "dome geometry" facing the interior of the container) and optional lateral rib (molding) structures for reinforcement. The above-mentioned (thermoplastic molding) method for producing the molded container, in particular blow molded body / container for medical / pharmaceutical preparations according to the present disclosure is basically suitable for thermoplastic plastics / materials if the disclosed unique features and suitability can be realized during the corresponding (thermoplastic molding) method.

[0090] In a preferred embodiment of a blow molded body / container or a blow molding method, it is advantageous for thermoplastics, such as polyethylene terephthalate (PET), that the thermoplastic raw material is not extruded in the form of pellets until the blow nozzle, but can be prefabricated in the form of a preform / blank / preform, so that then at the actual manufacturing and filling site, for example, by means of stretch blow molding, the (blow molded) molded body / container according to the present disclosure can be obtained in its final size and shape. For example, a preferred PET preform with a volume of 220 ml can obtain a nominal filling volume of 4.7 liters of a (blow molded) molded container after blow molding / blowing out. This corresponds to a compression of the cargo hold by more than 10 times in order to transport the raw materials to the manufacturing site or to the site of filling with medical / pharmaceutical preparations, especially liquids. This advantageously supports a resource-optimized manufacturing method and an optimized supply chain, with a particularly advantageously reduced carbon footprint. However, molded containers can also be produced in a direct single-stage (thermoplastic) production process. Here, the molded container can be directly converted into its final shape starting from the similar properties of granules or pellets and / or thermoplastics. That is to say, in this case, the intermediate step when making the above-mentioned preform (for example PET preform) can be omitted.

DETAILED DESCRIPTION

[0112] Preferred embodiments of the present disclosure are described in more detail below based on the accompanying drawings.

[0113] First embodiment

[0114] Figures 1 to 5A blow molded body or (blow) molded container 100 is shown as a molded container according to the present disclosure, in particular a blow molded container, according to a first preferred embodiment. The unfilled (blow) molded body / container 100, which can be filled (from above) via an (optionally) open container neck 70, is provided for accommodating a medical and / or pharmaceutical preparation (not shown; denoted by reference numeral 2, cf. Fig. 9 With regard to the filled end product based on the (blow-molded) molded body / container 100). For this purpose, the (blow-molded) molded body / container 100 is made of a thermoplastic, in particular inert, suitable for filling and storing medical and / or pharmaceutical preparations. That is, the (blow-molded) molded body / container is constructed or (three-dimensionally) formed using a thermoplastic production method or molding method. In particular, the (blow-molded) molded body / container 100 can be (blow-molded) in a technical thermoplastic grade / type, in particular a blow molding grade / type (that is, according to the so-called melt flow index that can be used in a thermoplastic molding machine, in particular a blow molding machine), in particular PET.

[0115] Especially refer to Figure 1 and 2c In the side view, the (blow-molded) molded body / container 100 has a bottom section 20, which has an end-side bottom surface 11 at the end of the body section 50. At the other axially opposite end of the body section 50, the (blow-molded) molded body / container 100 has a shoulder section 80, which has an open container neck 70 in its axial extension or opens into the container neck. Figure 1 and Figure 2c The shoulder section 80 of the container (center: upper) widens radially outward from the container neck diameter d-70 to transition to the body section 50 with the (essentially vertically extending) lateral outer cover surface 60. Here, the container neck 70 is arranged centrally in the shoulder inner region 81 of the shoulder section 80 radially inwardly around the (central) axial axis Z. The container neck 70 can be closed by means of an exemplary screw cap with an internal thread (not shown; with reference numeral 90, see Fig. 9 With regard to the final product), the container is closed by providing an external thread 75 on the container neck 70 .

[0116] Furthermore, the (blow) mouldings / containers 100 are designed to be stacked vertically during transport and / or storage. Figure 1 , 2a As can be seen in FIGS. 3 and 4 , firstly in the bottom surface 11 of the end side of the bottom section 20, an (optional) bottom groove 30 in the form of a substantially cup-shaped recess is recessed into the container interior in the direction of the axial axis Z (“dome geometry”). Figure 1As shown in particular in FIG, the bottom groove 30 tapers in a cup-shaped manner in the direction of the container interior over the bottom groove depth t-30, more precisely starting from a first bottom groove diameter d-31 on the opening side to a second bottom groove diameter d-32 (e.g., 60 mm) on the base side of the inner bottom groove base. Along this taper, the bottom groove 30 comprises a bottom groove shoulder 33 with a third bottom groove diameter d-33 that tapers in a step-like manner toward the bottom groove depth t-30 (e.g., 52 mm).

[0117] Bottom groove 30 (“dome geometry”, see in particular Figure 1 ) especially from Figure 3 The geometric "cooperation" shown in FIG. 1 is designed and shaped so as to accommodate other identical (in particular, multiple identical) (blow-molded) molded bodies / containers 100 for vertical stackability. Figure 3 The blow molded body / (blow) molded container 100 (if necessary, using Fig. 9 90) shown in the closed / closable container neck 70.

[0118] At the same time, the bottom groove 30 ("dome geometry") reduces the residual volume remaining near the bottom surface 11 by accumulating, in particular, liquid agent. The (nominal) filling volume of the blow molded body / (blow) molded container 100 is thus optimized or almost completely ensured, since only a small residual amount remains in the (blow) molded body / container 100 during removal, for example, by means of a suction connection / spout (as is the case, for example, in dialysis equipment according to the present disclosure). Figure 2c , the (nominal) filling volume is depicted by means of a (nominal) filling height distance sF (e.g., approximately 41 mm) which defines the desired filling height measured from the uppermost edge of the (blow) molded body / container 100. In this case, the (nominal) filling volume of the (blow) molded body / container 100 can be, for example, approximately 4.7 liters.

[0119] In addition, with the help of Figures 1 to 5 The special molding on the bottom side, for example the shoulder side, and its function in cooperation for vertical stackability are described in more detail. On the one hand, the special molding on the bottom side can be seen, Figure 1 , 2a , 2c, 3 to 5, wherein now particular attention is paid to the bottom surface 11 outside the bottom groove 30 as a relief-like bottom contour surface. On the other hand, in a first approximation, there is a specific shoulder-side molding structure complementary to the other. Figure 1 , 2b, 2c, 3, 5. In principle, it is conceivable to produce special molded structures or form fits (depending on the optionally independently claimed aspects) by any desired, in particular thermoplastic molding methods, such as blow molding, injection molding, etc.

[0120] The two corresponding shaped structures on the bottom side, such as the shoulder side, in a co-operating / three-dimensional form fit provide a significant stability of two identical stackable / stackable (blow-molded) shaped bodies / containers 100, 100. In particular, Figure 3 For this purpose, a special, segmentally axially spaced-apart form fit is provided according to the disclosure, by Figure 2b The longitudinal section of the section plane AA defined in FIG. 1 shows a relevant cutout of a vertical stacking assembly 200 of two identical blow molded bodies / (blow) molded containers 100, 100 (overlapping each other). The form fit prevents / reduces lateral twisting and improves vertical stackability, thereby achieving the effect of anti-rotation / "twist-resistant" stackability:

[0121] The bottom surface 11 outside the bottom groove 30 is formed into a relief-like bottom contour surface. For this purpose, four axially retracted bottom recessed molding segments 22 ("concave") are formed alternately / adjacently with four axially protruding bottom load contact molding segments 24 ("convex"). That is, the bottom contour surface is three-dimensionally contoured in relief by the 4+4 molding segments that alternate their axial "height planes / lines". Here, the four bottom load contact molding segments 24 protrude or extend beyond the bottom recessed molding segments 22 located therebetween (towards the bottom surface 11 / towards the direction of the supporting surface). That is, the four bottom recessed molding segments 22 are therefore not part of it, which firstly involves the supporting surface of the (blow-molded) molded body / container 100. Here, the four bottom recessed molding segments 22 are respectively flatter or shortened in terms of axial values ​​relative to the four bottom load contact molding segments 24.

[0122] Especially refer to Figure 2a and Figure 4 , corresponding or all four bottom concave molding segments 22 extend radially. It can be seen here that (optionally) each bottom concave molding segment 22 extends radially from the first bottom groove diameter d-31 of the opening side of the bottom groove 30 in the transition portion of the bottom surface 11 to the outer periphery of the bottom surface 11 (in the transition portion to the outer cover surface 60).

[0123] As long as the (blow) moulding / container 100 is essentially cuboid, with an essentially rectangular, almost square cross section (see in particular Figure 2a , 2b , 4, 5), the bottom section 20 is formed to have four corners in a cross-sectional plane perpendicular to the axial axis Z. Figure 2a, an exemplary molding container width B may be 148 mm; an exemplary molding container depth may be 158 mm. Figure 2c , an exemplary molded container height h-100 (i.e., the entire height, in general) can be 290 mm; an exemplary molded body height h-99 (without container neck 70) can be approximately 270 mm. In the transition to the associated cover surface 60, the (blow) molded body / container 100 can have vertical side edges that are rounded with the container edge diameter D (e.g. 185 mm). In particular, as with Figure 2a and Figure 4 It can be seen in FIG. 1 that all four bottom-side corners each have four bottom load-contacting profiled segments 24 , which serve for a uniform, essentially symmetrical load distribution.

[0124] As can be seen from the three-dimensional structure, especially with respect to the shoulder side Figure 1 , 2b / c, 3, 5 can be seen that on the outside of the container neck 70, the relief shoulder section 80 forms four protrusions / convex shapes (at Figure 2b It is clearly visible in the top view of the embodiment that the shoulder-protruding molded segments 82 arranged in a cross shape between the corresponding adjacent / intervening shoulder load contact molded segments 84 are arranged. Figure 3 For the (vertical) stackability of the stackable (blow) molded bodies / containers 100, 100, four shoulder-protruding molded segments 82 (at Figure 3 In the middle: each shoulder protruding molding segment in the lower (blow molded) molded body / container 100) is shaped to match or be arranged so that it is respectively connected to (in Figure 3 Center: The corresponding bottom depression molding segments 22 of the upper (blow-molded) molding / container 100 are arranged complementary to each other.

[0125] The load contact surface (in the context of the longitudinal section plane; also cf. Figure 1 and Figure 2c Reference symbol K) in FIG. 8 is divided (exclusively) on the shoulder side into a shoulder load contact profiled segment 84 (flat lying within the cross-sectional plane).

[0126] Therefore, especially Figure 3It can be seen that the corresponding or all four bottom recessed molded segments 22 of the vertically stackable / stacked (blow molded) bodies / containers 100, 100 are shaped to fit or are arranged so as to be spaced apart without contact with the shoulder segment 80 of the same / another (lower) (blow molded) container 100 when stacked into a vertical stacking assembly 200. The contact-free spacing defines the gap dimension S. Therefore, only the bottom load-contacting molded segment 24 of the (upper) (blow molded) container 100 forms a load-bearing load contact surface on the other (lower) shoulder segment 80. Again / complementarily to this, on the shoulder side, the load contact surface is divided into four shoulder load contact molded segments 84. Here, the four shoulder load contact molded segments 84 are flatly constructed in a cross-sectional plane of the shoulder segment 80 perpendicular to the axial axis Z (see in particular). Figure 1 and Figure 5 ).

[0127] That is to say, the vertically stackable / stacked (blow) molded containers 100, 100 (only) contact each other at / via the load contact surface. This interaction by the special molding structure is sufficiently stable against undesired relative movements.

[0128] To this end, the four (lower) shoulder-shaped segments 20 are stacked to form a vertical stack assembly 200 ( Figure 3 and Figure 7 ) are form-fitted or arranged so that when stacked they engage in a form-locking manner in four bottom recessed shaped segments 22 of the same / other (upper) (blow) molded container 100. Thus, in the vertical stacking assembly 200, the shoulder-side shaped structure and the bottom-side shaped structure and thus the two (blow) molded containers 100, 100 are prevented from twisting relative to (to each other) about their own (here coinciding) axial axes Z.

[0129] If, as described above, the bottom section 20 is formed as a rectangle with four corners, wherein the corners have the bottom load-contacting profiled segments 24 corresponding to the corner sides, the profiled contour on the shoulder side complementarily forms a cross-shaped arrangement of the corresponding four shoulder-projecting profiled segments 82. Figure 1 , 2b , 2c, 5, four complementary shoulder protruding molding segments 82 are arranged in a cross shape around the container neck 70 and extend radially from the container neck. Figure 5 As shown in the three-dimensional view of FIG, four complementary shoulder protruding molding segments 82 merge into the container neck 70 with a continuously extending contour line. Figure 5, where four complementary shoulder-projecting profiled segments 82 (this refers to opposite directions) merge broadly into the outer cover surface 60 in the beginning body section 50. According to this profiled contour, each of the four (comparatively set back) shoulder-side corners, each including the shoulder load-contacting profiled segment 84, is surrounded / annularly enclosed by a protruding / stepped shoulder-projecting profiled edge 89 with a substantially rounded course, which creates an impression similar to the shape of a suitcase corner.

[0130] For further protection against rotation and stabilization in the region of the load contact surface of the vertically stacked (blow) molded containers 100, 100, a bottom side (see in particular Figure 2a and Figure 4 ) For each corresponding corner side bottom load-contacting profiled segment 24, a pair of radial grooves 28, 28 are formed as paired arrangement / two convex (or conversely not shown variant: concave) contoured (at least partially radially extending) bottom profiled structural elements entering the container interior. Complementarily thereto, on the shoulder side (see in particular Figure 2b ) For each corresponding angular side shoulder load contact forming segment 84, a pair of radial longitudinal ridges 88, 88 are formed as paired / two convex (or conversely not shown in the variant: concave) contoured (at least partially radially extending) shoulder forming structural elements. That is, correspondingly / for each angular side, a pair of radial grooves 28, 28 as bottom forming structural elements are matched (or form-fitted) with the corresponding pair of radial longitudinal ridges 88, 88 as shoulder forming structural elements. That is, in the sense of improved stability of the vertical stacking assembly, the radial longitudinal ridges 88, 88 (from above) can be said to engage / press / grasp into the matching radial grooves 28, 28 (at the bottom) so as to abut against each other in a form-locking manner. This serves to further protect the tower-shaped stacking assembly 200 ( Figure 7 ) to prevent the (blow) molded containers 100, 100 from sliding, twisting, or tilting.

[0131] In addition, as in Figure 1 , 2c As shown in Figures , 4 and 5, the (blow) molded container 100 optionally has a molded portion with multiple (reinforcing) ribs 55, 55, ... extending parallel to each other, and the ribs have rib grooves 57, 57, ... located therebetween, and the rib grooves basically surround the main body section 50 transversely / perpendicularly to the axial axis Z (that is, a "horizontal" rib structure).

[0132] Second and third embodiments

[0133] Figure 6a and 6bA side view of a (blow) molded body / container according to the disclosure is shown, respectively, according to a second or third preferred embodiment, which side view is optionally modified compared to the first preferred embodiment (with regard to the "horizontal" rib structure), so that otherwise reference is made to the above description: The molded part of a plurality of (e.g. seven) mutually parallel ribs 55, 55, ... surrounding the body section 50 has an (optional) V-shaped course with a central apex. In this case, the apex of the V-shaped molded part ribs 55, 55 can be determined according to Figure 6a Directed toward the shoulder section 80 or selectively according to Figure 6b Points toward the bottom section 20 .

[0134] Stacking assembly (first embodiment)

[0135] In order to avoid repetitions, reference is explicitly made to the above description of the first embodiment of the molded container 100, in particular the blow-molded container, and in particular to the embodiment according to Figure 1 and Figure 3 Implementation plan: First, Figure 7 A side view of an exemplary vertical stack of three identical (blow-molded) molded bodies / containers 100, 100, 100 according to the present disclosure is shown, wherein the corresponding partial cross-sectional views shown in pairs are similar to Figure 3 And refer to Figure 2b The section plane AA is defined in . Figure 8 A side view of an exemplary horizontal stacked assembly 200 ′ of four identical (blow-molded) shaped bodies / containers 100 , 100 , 100 , 100 according to the present disclosure is shown.

[0136] Third and fourth embodiments

[0137] Optionally (see first embodiment) a sheet-like or film-strip-like carrying handle 113 is / can be fixedly arranged on the molded container 100 , in particular a blow-molded container, in particular bonded thereto.

[0138] Here, the carrying handle 113 is formed between two carrying handle ends 118, 118 and a carrying handle middle section 119 extending axially in an arc shape on the other side of the shoulder section 80. Here, the carrying handle 113 is adhered tangentially with its two opposite carrying handle ends 118, 118 to two corresponding connection points P of two opposite outer cover surfaces 60 of the (blow) molded container 100 / body section 50. Here, the carrying handle 113 is respectively arranged eccentrically with respect to the two connection points P. As in particular Fig.10 As shown in FIG. 1 , the carrying handle 113 is arranged offset in the transverse direction from a perpendicular point L in a cross-sectional plane lying on the axial axis Z.

[0139] The handle 113 is tilted at two connection points P to the axial axis Z. The selected handle tilt angle {90°-W} defined between the axial axis Z and the longitudinal extension of the handle 113 is approximately 32 degrees (relative to the vertical).

[0140] As in Fig. 9 As shown in the figure, an exemplary end product based on a (blow-molded) molded body / container 100 according to the present disclosure is filled with a medical and / or pharmaceutical preparation 2, such as a dialysis solution or a solid dialysis concentrate, and is subsequently closed in a leak-proof manner using a screw cap 90 as a closure. In addition, a sheet label 95 is applied to the blow-molded container, which sheet label can be, for example, a film-adhesive label (e.g. with a transparent film edge) that is printed / printable with a product marking (not shown) regarding the content and use of the contained preparation 2, etc.

[0141] Fifth and Sixth Embodiments

[0142] Optionally (see first embodiment) a T-shaped handle 111 is provided / can be provided on the (blow) molded container 100 as a T-shaped, dimensionally stable molded handle, see Fig.11a and 11b , or a U-shaped handle 112 is provided / can be provided as a U-shaped shape-stable molded handle, see Fig.12a and 12b .

[0143] The T-shaped handle 111 or the U-shaped handle 112 is respectively attached to the container neck 70 in a cylindrical section provided therefor as a handle receiving section 78 (see Figure 1 , 2c , 5). The T-handle 111 or the U-handle 112 has a proximal (relative to the container neck 30) molded handle ring section 115 so that it can be attached to the container neck 70 (here in a non-detachable manner) by means of the molded handle ring section. In addition, the T-handle 111 or the U-handle 112 (at its opposite end) has a distal T-shaped or U-shaped molded handle holding section 116, which (starting from the molded handle ring section 115) extends essentially radially from the container neck 70.

[0144] If with the help of Fig.11b , which shows a partial longitudinal section of a stack assembly 200 of two identical (blow) molded bodies / containers according to the present disclosure according to a fifth embodiment, and is illustrated by a T-shaped handle 111, for example ( Fig.11b The bottom recessed molding segments 22 of the upper (blow molding) molded container 100 can be shaped or arranged to fit together with ( Fig.11bThe shoulder section 80 of the other (blow) molded container 100 (in the lower part) is spaced apart without contact from a minimum gap dimension S which exceeds the maximum axial mold handle outer dimension G of the distal mold handle holding section 116.
