Description

Technical area

[0001] The present invention relates to packaging technology, in particular to the integration of additive manufacturing for the production of packaging elements with optimized shock-absorbing properties. In particular, the present invention relates to a transport protection device, produced, among other things, by 3D printing, with a special lamella structure that effectively protects shock-sensitive goods during transport from mechanical influences such as shocks, vibrations, or pressure. The lamellae are designed to offer optimal energy absorption and flexibility, with the geometry and material selection being individually adaptable through the additive manufacturing process. The invention relates to a transport protection device for protecting transported goods, a flexible insert for this device, and methods for producing the transport protection device and the insert using additive manufacturing.

[0002] The invention further encompasses a transport protection device for pneumatic tube systems, which can be used as an insert in pneumatic tube carriers. Pneumatic tube systems are technical systems that enable the rapid and safe transport of containers containing documents or goods through a network of tubes using positive or negative pressure. State of the art

[0003] In packaging technology, various methods and materials are used to protect products from mechanical stress such as shock, vibration, and pressure during storage and transport. A central goal is to ensure the integrity and functionality of the packaged goods. Classic packaging materials include corrugated cardboard, foams, bubble wrap, and special molded parts tailored to the geometry of the respective product. The selection and design of the packaging takes into account factors such as the weight, sensitivity, and value of the packaged goods, as well as the expected stresses during transport. Shock absorption is an essential element in packaging technology to minimize the effects of sudden mechanical impacts.For this purpose, materials with defined damping properties are used that absorb kinetic energy and convert it into heat or dissipate it through elastic deformation. Typical shock-absorbing materials are expanded polymers such as EPS (expanded polystyrene), EPP (expanded polypropylene), or PUR foams.

[0004] Additive manufacturing, also known as 3D printing, describes generative manufacturing processes in which components are built layer by layer directly from digital models. The most important additive manufacturing processes include selective laser sintering (SLS), fused deposition modeling (FDM), and stereolithography (SLA). These technologies enable the production of complex geometries, individual adaptations, and the integration of functions that are difficult or impossible to achieve using conventional manufacturing methods. In packaging technology, additive manufacturing opens up new possibilities for customized packaging solutions, especially for small series, prototypes, or products with special form and function requirements. These technologies are used in these areas, among others, in the consumer goods industry, the electronics sector, mechanical engineering, medical technology, and logistics.

[0005] The protective packaging currently used for the transport of sensitive and fragile goods, especially in pneumatic tube systems, has significant deficiencies. A key problem is that this packaging does not provide adequate protection against kinetic impacts such as impacts or sudden changes in acceleration. This frequently results in damage to the transported load, especially when different formats and geometries are transported together. This poses a particular problem for medical applications, such as in hospitals, when medical samples or medications are sent via pneumatic tube.

[0006] Another problem concerns the materials used: Conventional packaging solutions are often not sterilizable or difficult to clean. This poses a significant risk, particularly in sensitive areas such as medical logistics, as effective prevention of cross-contamination and hygiene problems cannot be guaranteed. Furthermore, existing packaging solutions are generally not designed for multiple use. They are usually used only once, leading to repeated one-off costs and increased resource consumption. This is not only economically inefficient but also pollutes the environment through increased waste and material usage. A further deficit is the lack of options for precise documentation and monitoring of the transported contents. Without suitable labeling systems, seamless traceability of the cargo is difficult.Finally, existing solutions often do not adequately consider the varying geometries and formats of the loads to be transported. This results in loads not being optimally secured or separated, increasing the risk of damage from collisions within the packaging and resulting in inefficient protection.

[0007] When transporting sensitive goods, there is a need to transport them safely.

[0008] The invention aims to provide a transport protection device that ensures safe, flexible and reusable protection for different container sizes and shapes during transport, for example, but not limited to, in pneumatic tube systems.

[0009] The present invention relates in a first aspect to a transport protection device comprising a casing having a housing and a cover, wherein the cover can be mechanically connected to the housing.

[0010] The casing is arranged, for example, around a first axis, and the inside of the casing has inner lamellae, wherein the inner lamellae extend longitudinally parallel to the first axis. The outside of the casing optionally has outer lamellae. The transport protection device is designed such that the casing can be formed as a cylindrical or tubular element, wherein the first axis preferably corresponds to the longitudinal axis of the casing. Instead of lamellae extending along one direction, a plurality of raised elements arranged one behind the other can also be used. For example, a row of spikes could replace a lamella, these being, for example, thin cones, or cone-like structures, wherein the cone base is arranged on the surface and the cones are arranged in a row that replaces the lamella, i.e.the cones are arranged adjacently and spaced apart on the surface where, in the case of a slat, the slat is arranged. Instead of replacing the slat with points or spikes, the slats can also be segmented, interrupted or offset. The slats can also be grid-shaped or consist of a series of bars. The slats or spikes are a concrete embodiment of a movement-inhibiting and / or shock-absorbing component. Within the scope of the invention, one or more suitable movement-inhibiting and / or shock-absorbing components can be used instead of the slats. These can be arranged regularly or randomly on the outer or inner surface of the transport protection device or of the insert for the transport protection device described below.These motion-restraining and / or shock-absorbing components should be designed to space the respective surface from other objects, surfaces, inserts, or other components. Furthermore, the components should be flexible to absorb kinetic energy through deformation. For example, if the transported load is tightly enclosed or held by the motion-restraining and / or shock-absorbing components, an externally applied acceleration can be converted into deformation of the motion-restraining and / or shock-absorbing components, so that the acceleration is not fully transmitted to the transported load.

[0011] The cylindrical shape is advantageous when the transport protection device is used in pneumatic tube systems as an insert for pneumatic tube carriers. However, the transport protection device is not restricted to this shape. The housing, together with the lid, forms an enclosed space intended to hold containers or other sensitive objects to be transported. The transported goods can be, for example, tubes, jars, cans, bottles, small tubes, syringes or blisters. The mechanical connection between the lid and the housing can be made, for example, by a joint and, if necessary, in combination with a screw, snap or bayonet closure to ensure a secure and removable connection. In particular, the lid can be closed using rubber bands.The inner lamellas on the inside of the shell serve to secure the containers inside and protect them from shocks or vibrations during transport. The longitudinal alignment parallel to the first axis ensures even force distribution along the length of the shell, increasing the stability of the transport protection device. The lamellas can be arranged to ensure a defined distance between the container and the shell wall, thus offering additional protection against mechanical impacts. The lamellas are elastic. This elastic design allows for increased dissipation of introduced kinetic energy. The outer lamellas on the outside of the shell are designed to further increase the structural strength of the container and can also serve as spacers, for example when stacking multiple containers or during transport in larger packaging units.In particular, the outer slats can serve as elastic shock-absorbing elements when the transport protection device is used as an insert in a pneumatic tube carrier. In a pneumatic tube system, the elastic slats can dampen shocks such as acceleration peaks in curves or free fall at the exit or end of a system, as well as impacts at the end of the system. The outer slats can extend so far outwards that the transport protection device sits excessively in the pneumatic tube carrier, relative to its diameter defined by the outer slats, and is thus fixed in place. The outer slats can also help to improve the grip of the container and facilitate handling during manual or mechanical handling. The transport protection device is particularly suitable for the safe transport of sensitive or valuable containers where increased protection against mechanical stress is required.The combination of inner and outer slats optimizes both the stability of the container and the protection of the contents. In a further embodiment, the slats can also be wave-shaped, curved, or serrated to fulfill the same protection and spacing purpose. The transport protection device can preferably be manufactured using an additive process; in particular, the slat structure along one axis allows the transport protection device to be manufactured using 3D printing, preferably using the FDM (fused deposition modeling) process, without a support structure. This saves material, time, and energy. The transport protection device, in particular the casing and the slats, can alternatively be manufactured using conventional methods such as injection molding.It is also possible for the slats at the ends of the upper and lower sections to extend further into the center to prevent the load from escaping during sudden acceleration by increasing energy dissipation. The containers to be transported can have any shape within permissible dimensions.

[0012] In a preferred embodiment, the transport protection device can have a cylindrical or prismatic shell. The shell is designed such that it either has a circular cross-sectional shape and is thus formed as a cylinder, or alternatively has a prismatic shape with a polygonal cross-section, for example rectangular, square, or hexagonal, etc. The shell can be closed off by a base element and a cover element at its longitudinal ends. The cover and base elements can be or include shock-absorbing impact elements. The choice of shell shape can be based on the requirements of the goods to be transported or on logistical specifications. By designing the shell as a cylinder or prism, the transport protection device can be adapted to different areas of application. The inner lamellas can be connected to the impact body, in particular directly.This arrangement stabilizes the slats, preventing them from being “simply pushed to the side” under load.

[0013] A cylindrical shell offers the advantage of even force distribution and is particularly suitable for applications where the container is used as an insert in pneumatic tube carriers or in round receptacles. A prismatic shell, on the other hand, can enable better use of space during stacking or storage and is particularly advantageous when several containers are to be placed next to each other. The shell can also be rectangular. It is also conceivable for the shell to have other geometric designs that represent a combination of cylindrical and prismatic elements or are specifically adapted to the shape of the object to be protected. The selection of the shell shape is preferably dependent on the respective transport requirements and the expected mechanical loads.The inner and outer lamellas can be adapted to the selected casing shape, ensuring optimal protection and high stability in both cylindrical and prismatic designs. The inner lamellas are preferably designed in such a way that they project towards the interior or a central axis of the transport protection device. "Towards the interior" means that the lamellas project from the inside of the casing into the interior. The direction of the inner lamellas can be radial relative to the longitudinal axis or non-radial. The casing can be manufactured from various materials, for example, plastic or composite materials, whereby the choice of material can be adapted to the respective casing shape and the requirements for strength and weight. The material is preferably media-resistant, i.e.It can be cleaned with a cleaning agent and rinsed out or cleaned in another way with a cleaning agent without causing any damage. The connection between the housing and the lid remains mechanically secure and detachable / movable, regardless of the casing shape. In addition, the housing and lid can be firmly connected to one another with an articulated joint for quick and safe loading and unloading. Multi-part designs can also be made, for example with the lid being removable or pivoting. In addition to the usual round, cylindrical shape of the pneumatic tube carrier, the protective packaging can also be designed for other geometries. The pre-tensioned outer lamellas enable an elastic, almost form-fitting connection with the environment and / or the transported goods, so that the transported goods are held securely even with deviating cross-sectional shapes.

[0014] In a further embodiment, the transport protection device can comprise an insert arranged in the interior of the transport protection device. This insert is preferably flexible and has a base area, wherein slats can be arranged on a first side of the base area, and wherein the second side of the base area can at least partially rest against the inner slats of the transport protection device. The slats of the insert are directed inwards so that they point towards the interior of the transport protection device. The flexible insert can, for example, be made of an elastic plastic, e.g. TPU, or another suitable flexible material. The flexibility of the insert makes it possible to securely accommodate and fix different container shapes or sizes in the transport protection device.The slats on the first side of the base of the insert can be designed in such a way that they adapt to the contour of the respective container and thus ensure a form-fitting hold. In particular, if the insert is cylindrical or quasi-cylindrical, the distance between the inner slats can certainly be reduced towards the inside and be less than the distance between the slats on the surface of the base of the insert. As a result, the inner slats of the insert converge towards the inside of the cylindrical or prismatic insert. The second side of the base preferably rests against the inner slats of the shell, which stabilizes the insert in the container and can prevent slipping during transport. The slats can be arranged on the insert in various ways. For example, the slats can be arranged radially, concentrically or parallel to one another.The slats can vary in height, width, or rigidity to allow for optimal adaptation to the transported goods. For example, instead of a continuous slat, as described above, a series of spikes, cones, or bars can be used. The spikes, cones, or bars are preferably aligned with their longitudinal extension perpendicular to the casing surface. It is also conceivable for the insert to be designed to be replaceable or removable, so that the transport protection device can be used flexibly for different applications. By using a flexible insert with slats, the protection of the transported goods can be further increased, as shocks and vibrations are additionally cushioned.Like the inner and outer lamellae of the transport protection device, the elastic lamellae of the insert can absorb and absorb shocks and kinetic energy through deformation. The lamellae of the insert can be designed to keep the transported goods at a distance from the casing walls, thus minimizing the risk of damage from direct collision with the casing. The combination of the inner lamellae of the casing and the lamellae of the flexible insert enables particularly safe and careful storage and transport of sensitive or valuable goods. In one possible embodiment, the protective packaging can securely enclose different container shapes and keep them at a distance using concentrically arranged, planar and parallel lamellae in order to prevent collisions between the containers and the casing of the transport protection device.The concentric arrangement of the slats enables an even distribution of the holding forces and ensures stable fixation of the transported goods inside the container. The design of the slats, which are parallel to the longitudinal axis of the casing, also ensures extensive contact with the container, whose extension direction is preferably also parallel to the slats, further improving protection against mechanical impacts.

[0015] In a further possible embodiment, the inner slats of the transport protection device can be arranged concentrically. The inner slats preferably run towards the center of the container. Such an arrangement of the inner slats can contribute to securing and protecting the transported goods inside particularly evenly. The concentric alignment enables the slats to surround the transported goods on all sides, thus creating a uniform distance all around between the goods and the casing wall. It is also conceivable for the inner slats to be designed such that they extend radially from the casing towards the center. This can achieve particularly effective damping of shocks and vibrations, since the forces occurring are evenly distributed across the concentrically arranged slats.The concentric arrangement can also increase the stability of the entire transport protection device and further reduce the risk of damage to the contents. Alternatively, the slats can be arranged in several concentric levels, so that different layers of slats surround the transported goods. This can be particularly advantageous for sensitive or valuable goods, as it provides additional protection against mechanical impacts. Designing the slats as concentric structures can also improve the adaptability of the container to different package shapes, as the slats can flexibly adapt to the contours of the respective transported goods. The concentrically arranged slats can be manufactured, for example, by injection molding or other suitable manufacturing processes.It is also possible for the slats to vary in height, thickness, or stiffness to achieve optimal protection. Choosing a concentric arrangement and orienting the inner slats toward the center can therefore be used as an advantageous option to further improve the protective and securing properties of the transport protection device.

[0016] In one possible embodiment, the transport protection device can be made of a flexible, sterilizable material such as thermoplastic polyurethane (TPU). The concentrically arranged, flat slats can be designed to securely enclose and separate various goods of different sizes and shapes, preventing collision damage, particularly during transport in pneumatic tube systems. Alternatively, other flexible and sterilizable materials can be used, provided they offer the desired protective and hygienic properties. The design of the slats can be adapted to the specific requirements of the respective application.

[0017] In a further advantageous embodiment, the outer slats can be arranged concentrically. The outer slats can be designed such that they extend outwards from the center of the transport protection device. Such an arrangement of the outer slats makes it possible to absorb and dissipate external forces particularly efficiently, since the slats run radially outwards from the center point and any impacts or pressure loads that occur can thus be evenly distributed over the outer surface. It is conceivable for the concentrically arranged outer slats to have different radii or distances from one another in order to enable graduated damping or targeted adaptation to different external loads. The outer slats can, for example, be arranged in several concentric planes, with each plane assuming a specific damping function.Likewise, the number, thickness, or material of the outer slats can be varied to adapt the protective effect to the specific transport requirements. Alternatively, the outer slats can be designed not only concentrically, but also in combination with other geometric arrangements, such as spiral or segmented. Aligning the outer slats from the center outwards can help the transport protection device respond flexibly to different external influences and ensure optimal shock absorption. The design of the outer slats can also be selected so that they can be adapted to different transported goods or packaging requirements. For example, the slats can be made of an elastic material that deforms under load and then returns to its original position.This enables repeated use of the transport protection device and increases its service life. Overall, a concentric arrangement of the outer slats, directed from the center outward, offers an additional option for further improving the protective effect of the transport protection device and adapting it to the specific transport conditions.

[0018] In a further preferred embodiment, the transport protection device can have a first axis along which the transport protection device is mainly movable, i.e. the direction in which the transport protection device is primarily to be moved during transport. This first axis can in particular be designed as the longitudinal axis of the container. The transport protection device can be designed such that the transport protection device can be transported along this axis, for example as an insert in a pneumatic tube carrier in a pneumatic tube system, on a conveyor belt or in another automated transport device. The orientation of the casing and the arrangement of the inner and outer slats can be adapted to the direction of movement along the first axis in order to ensure optimal guidance and stability during transport.Designing the transport protection device with a defined first axis allows the container to be moved in a specific direction, which is particularly advantageous in automated transport systems. The slats can be arranged so that they run parallel or concentrically to the first axis. It is also possible for the first axis to serve merely as a reference for the construction and design of the transport protection device, without specifying a mandatory direction of movement. The selection and orientation of the first axis can thus be flexibly adapted to the specific requirements of the transport and the objects to be protected.

[0019] In a further preferred embodiment, the transport protection device can be provided with impact absorbers at its longitudinal ends. These impact absorbers can be made, for example, of an elastic or shock-absorbing material and serve to effectively dampen the shocks or impacts that occur during transport on the end faces of the device. By arranging the impact absorbers at the ends of the transport protection device, the protective effect can be further improved, particularly under axial loads. The impact absorbers can serve as the cover and base of the transport protection device.

[0020] It is also possible for the impact absorbers to be equipped with a recessed handle. Such a handle can be integrated into the impact absorbers and allows for comfortable gripping and carrying of the transport protection device. The integration of a handle can facilitate handling during loading and unloading as well as during transport in general. Furthermore, the slats can be firmly connected to the impact absorbers at their ends. Such a connection can help prevent the slats from slipping or becoming loose in the event of an impact, thus ensuring a long-lasting and reliable protective function. The firm connection of the slats to the impact absorbers can be achieved, for example, by gluing, welding, or mechanical connections such as clipping or printing as a common structure.In an alternative embodiment, the slats can overlap along the longitudinal axis of the transport protection device to prevent objects from slipping out. The overlapping slats can be designed to form a continuous protective shell while simultaneously allowing flexible adaptation to different transported goods. Furthermore, it is conceivable for the slats to be connected at each end to cylindrical impact absorbers, which ensure progressive energy dissipation in the event of impacts. The cylindrical shape of the impact absorbers allows the energy generated during impact to be gradually absorbed and dissipated, further reducing the load on the transported goods. The combination of overlapping slats and cylindrical impact absorbers thus offers particularly effective protection against slipping and against mechanical impacts during transport.In general, the impact absorbers can be adapted to the shape of the transport protection device.

[0021] In another possible embodiment, the transport protection device or the insert of the transport protection device can be made of a flexible material. For example, thermoplastic polyurethane (TPU) can be used as the flexible material. The use of a flexible material such as TPU enables the device or insert to react elastically to external forces and return to its original shape after deformation. This can further improve the protective effect against shocks and vibrations. Alternatively, other suitable flexible plastics or elastomers can be used, provided they exhibit the desired mechanical properties, such as elasticity, resilience, and resistance to environmental influences. The selection of the material can be adapted to the specific requirements of the transported goods and the area of ​​application, as well as the manufacturing process.For example, for applications where sterilizability is required, a suitably sterilizable flexible material can be selected. It is also conceivable for the transport protection device to consist of a material combination in which certain areas, such as the slats or the impact absorbers, are made of particularly flexible or shock-absorbing materials, while other areas are made of less flexible but more stable materials. Through the targeted selection and combination of materials, the protective function of the device can be further optimized. The use of a flexible material such as TPU also offers the advantage that the transport protection device can be used multiple times, as it retains its shape after stress and does not break or become permanently deformed.The cleaning and maintenance of the device can also be made easier by the choice of material, especially if smooth, washable surfaces are used.

[0022] In another possible embodiment, the slats of the transport protection device can be wave-shaped, curved, or serrated. For example, it is conceivable for the slats to have a wave-shaped geometry, which allows them to react particularly flexibly when subjected to force and achieve improved damping. Alternatively, the slats could be curved so that they deform elastically under load and thus effectively absorb any shocks or vibrations that occur. It is also possible for the slats to have a serrated structure. A serrated design can enlarge the surface area of ​​the slats, resulting in a larger contact area with the object to be protected or with neighboring slats. This can further improve the protective effect and enable an even more even distribution of forces.The selection of the respective slat geometry can be flexibly adapted to the requirements of the specific transported goods and the expected mechanical loads. For example, a wave-shaped or serrated slat structure may be preferred if particularly high shock absorption or targeted fixation of the transported goods is desired. It is also conceivable to combine different slat shapes within a transport protection device in order to realize different protective functions. In addition, the design of the slats can vary in terms of their shape, size, and arrangement to enable optimal adaptation to different areas of application. The slats can, for example, be of varying thickness or arranged in several levels so that they adapt to the contours of the transported goods and ensure effective cushioning.The choice between wave-shaped, curved or serrated slats can be made depending on the application and the desired level of protection.

[0023] In another possible embodiment, the transport protection device and / or insert can be manufactured using an additive manufacturing process, for example by means of 3D printing. Additive manufacturing offers the possibility of realizing complex geometries and individual structures, such as the inner and outer slats or special damping elements, in a single production step. It is conceivable that by using an additive process, the shape, arrangement, and material thickness of the slats can be specifically adapted to the respective requirements of the transported goods. For example, the wall thickness of the casing or the geometry of the slats can be varied locally in order to specifically reinforce certain areas or make them more flexible.Likewise, 3D printing can be used to directly integrate functional elements such as impact absorbers, handles, or flexible inserts without the need for subsequent assembly. Alternatively, only the insert, for example as a flexible damping element, can be additively manufactured, while the casing of the transport protection device is produced conventionally. It is also possible for only individual components, such as the inner or outer slats, to be produced using an additive process and then connected to other components. The use of additive manufacturing processes, especially 3D printing, enables a high degree of design freedom and the cost-effective production of even small batches or individual one-off pieces. In addition, the protective effect of the transport protection device can be further optimized by selecting suitable printing materials, such as flexible plastics or elastomers.Optionally, the additive manufacturing process can also be used to equip the transport protection device or insert with specific surface structures, markings, or adaptations to meet specific transport requirements. Manufacturing using 3D printing thus offers a wide range of possibilities for customization and functional integration that would be only partially feasible with conventional manufacturing processes.

[0024] In a further possible embodiment, it can be provided that the housing and the cover of the transport protection device have different colors. For example, the housing can be designed in a first color, e.g. red, and the cover in a second, different color, e.g. blue. The choice of colors can be arbitrary and adapted to the respective requirements or preferences. It is also conceivable for both the housing and the cover to be provided in several shades or with patterns in order to enable individual design or better differentiation. The use of different colors for the housing and cover can help to make the transport protection device easier to handle. Optionally, the color scheme can also be used to identify different variants, sizes or intended uses of the transport protection device.For example, different colors can be used to identify different protection classes, transported goods, or destinations. The selection and combination of colors can be flexibly adapted to the respective requirements. In a further embodiment, the color differentiation of the housing and cover can be used to enable clear orientation of the transport protection device during loading and unloading. For example, targeted coloring can indicate which side of the device should be facing up or forward during loading or unloading. This can help prevent incorrect operation and reduce the risk of accidental spillage or damage to the transported goods. The color coding can thus serve as a visual aid to support the correct handling of the transport protection device in daily use.Alternatively, additional markings or symbols can be provided in addition to the color scheme to further facilitate orientation.

[0025] In a further possible embodiment, it can be provided that the casing is arranged around a first axis. This first axis can, for example, be designed as the longitudinal axis of the transport protection device and serves as a reference line for the arrangement of the casing as well as the inner and outer slats. It is conceivable for the casing to be arranged rotationally symmetrically around this axis, thereby enabling an even distribution of the protective and damping elements. Alternatively, the first axis can also merely serve as a structural orientation along which the casing extends. Aligning the casing around such an axis can be particularly advantageous if the transport protection device is intended for applications in which a directed movement occurs, for example in pneumatic tube systems or automated conveyor systems.In such cases, orienting the casing around the first axis can help increase stability during transport and enable targeted damping of forces in the direction of movement. It is also possible for the geometry of the casing and the arrangement of the slats to be selected to support a preferred direction of movement along the first axis. The first axis can serve as an axis of symmetry, so that the shape and function of the transport protection device are oriented around this axis. In this context, the inner and outer slats can be arranged so that they run parallel or concentrically to the first axis, thereby ensuring a uniform protective effect over the entire length of the device. The selection and orientation of the first axis can be flexibly adapted to the respective requirements of the transport and the objects to be protected.For example, the first axis can also serve as a reference for the construction and design of the transport protection device, without requiring a specific direction of movement. By optionally arranging the casing around a first axis, the transport protection device can be adapted to different applications and transport requirements.

[0026] In a further possible embodiment, it can be provided that the outer slats are arranged concentrically around the first axis and extend longitudinally parallel to this first axis. For example, it is conceivable for the outer slats to be designed in the form of annular or segmented structures that concentrically surround the casing of the transport protection device. This concentric arrangement can contribute to enabling an even distribution of external forces over the entire surface of the device. Furthermore, the outer slats can be designed such that they extend in the longitudinal direction, i.e. parallel to the first axis. Such an alignment can be particularly advantageous if the transport protection device is preferably moved along this axis.The slats running parallel to the axis can efficiently absorb external shocks or pressure loads and dissipate them along the longitudinal direction, thereby further improving the protective effect for the transported goods.

[0027] In a further possible embodiment, it can be provided that the inner slats are arranged concentrically around a first axis. For example, it is conceivable for the inner slats to be designed in the form of annular or segmented structures that concentrically surround the interior of the transport protection device. Such a concentric arrangement can contribute to enabling an even distribution of forces inside the device and to supporting the transported goods from all sides. Furthermore, the inner slats can be designed such that they extend in the longitudinal direction, i.e. longitudinally parallel to the first axis. This orientation can be particularly advantageous if the transport protection device is preferably moved along this axis or if the goods to be protected have an elongated shape.The inner plates running parallel to the axle can help to efficiently absorb and dissipate shocks or vibrations that occur in the longitudinal direction.

[0028] In a further possible embodiment, it can be provided that the cover and the housing of the transport protection device are connected to one another in an articulated manner. The articulated connection can be realized, for example, by a hinge, a film hinge or another suitable joint construction. Such a configuration enables the cover to be movable relative to the housing, which facilitates the opening and closing of the transport protection device and supports comfortable handling when loading and unloading the transported goods. Preferably, the hinge axis can run parallel to a first axis of the transport protection device. Such an arrangement of the hinge axis can be particularly advantageous if the transport protection device has an elongated shape and is moved or handled along this axis.The parallel alignment of the joint axis to the first axis can help ensure that the lid can be opened or closed evenly over the entire length of the housing, thus enabling easy and safe insertion or removal of the transported goods. For example, the joint can be designed as a film hinge, whereby the material between the components (housing and lid) is weakened, for example in a parallel alignment to the longitudinal axis. This weakening allows the components to move relative to one another around the axis of the weakening. This design of the joint is particularly advantageous when the transport protection device is manufactured using additive processes such as 3D printing. It is also conceivable for the joint to be designed as a tongue and groove connection. Such a design can ensure a particularly stable yet flexible connection between the lid and housing.The tongue-and-groove design can be selected so that the lid is positively connected to the housing when closed and can be easily opened when needed. Alternatively, other hinged connection solutions can be used, provided they ensure reliable and repeatable function.

[0029] In another possible embodiment, the cover and the housing of the transport protection device can be connected to each other in a pluggable manner. With such a configuration, the cover can be placed on or inserted into the housing using a plug-in mechanism, for example. The plug-in mechanism can be designed to ensure a secure yet detachable connection between the cover and the housing.

[0030] In a further possible embodiment, it can be provided that a second insert is arranged in the interior of the transport protection device. The second insert can optionally be positioned inside the first insert. For example, it is conceivable that the second side of the base area of ​​the second insert rests on the inward-facing ends of the slats of the first insert. Alternatively, the second insert can be arranged behind the first insert in the longitudinal direction of the transport protection device. By arranging a second insert, the protective effect inside the device can be further increased or adapted to different transported goods. The second insert can be designed flexibly and can differ from the first insert in terms of its shape, size or material properties.It is also possible for the second insert to be specifically designed to additionally secure or cushion smaller or more delicate objects within the transport protection device. The arrangement of the second insert can be selected to ensure optimal adaptation to the specific requirements of the transported goods. Combining multiple inserts enables modular adaptation of the interior and can increase the versatility of the transport protection device. Optionally, up to two inserts of different colors can be used within the transport protection device. Color-coding the inserts improves clarity and allows for easy identification of each insert. This can be particularly advantageous when handling and unloading the transport protection device, as it provides visual instructions for safely removing the transported goods.The use of differently colored inserts can also help to safely accommodate a wider range of object sizes and further increase the adaptability of the device. Alternatively, the colored inserts can serve as visual markings for specific transported goods or for special handling instructions. Furthermore, the second insert can also be arranged longitudinally behind the first insert within the transport protection device. It is advantageous if the first insert and the second insert have the same or similar dimensions transverse to the longitudinal axis of the transport protection device.

[0031] In a further possible embodiment, the inner and / or outer slats of the transport protection device can be arranged in pairs in a V shape on the respective side of the casing. With such an arrangement, two adjacent slats together form a V shape, with the opening of the "V" being able to face either inwards or outwards. This V-shaped design of the slats can contribute to specifically influencing the damping properties of the device and enable particularly effective absorption and dissipation of impact or pressure forces. It is also conceivable for the slats arranged in pairs in a V shape to be arranged symmetrically and concentrically on the casing.Such a symmetrical and concentric arrangement can support an even distribution of the protective effect across the entire surface of the transport protection device and improve its adaptability to different load directions. The concentric alignment can be provided for both the inner and outer slats, resulting in a harmonious and functional structure. Alternatively or additionally, the slats arranged in pairs can be connected to one another via a web located on the surface of the casing. The web can in particular be a cylindrical tube or tubular profile incorporated into the casing surface, which is formed by the cover and housing. Such a web can, for example, be designed as a continuous connecting element between the two legs of the V-shape, thus increasing the stability of the slat arrangement.The connection via a web also makes it easier to position the slats on the casing and ensures long-term dimensional stability. The web can also be part of the casing or the casing surface. The web can be arranged either on the inside or outside of the casing, depending on whether the connection is to be made between the inner or outer slats. The design of the slats as pairs of V-shaped structures, their symmetrical and concentric arrangement and the optional connection via a web offer a wide range of options for adapting the mechanical properties and protective effect of the transport protection device to the respective requirements of the goods being transported and the area of ​​application. The choice of the respective design can be made flexibly and depends on the specific requirements for shock absorption, flexibility and stability.As well as the rigidity of the lid for more comfortable use.

[0032] In another possible embodiment, the slats can have a recess in their center. Such recesses can be designed, for example, as round, oval, rectangular, trapezoidal or other shaped openings. The size, shape and arrangement of the recess can be flexibly selected and is preferably based on the respective requirements for the damping properties and flexibility of the slats. By providing a recess in the center or elsewhere in the slats, the elasticity of the slats can be increased, so that they can yield more easily and deform better when force is applied. This can be particularly advantageous if particularly high shock absorption or targeted adaptation to different transported goods is desired.The recess can also help reduce the overall weight of the transport protection device without significantly compromising its protective effect. It is also possible that not all slats are provided with a recess, but only selected slats, for example, in certain areas of the transport protection device.

[0033] In a further possible embodiment, the slats can be tapered at their longitudinal ends. For example, it is conceivable for the slats to gradually narrow or become thinner towards their ends. This tapering can contribute to the slats responding more flexibly to mechanical loads and deforming more easily elastically when force is applied. In particular, the slats can be provided to taper down to the surface of the casing. In such a configuration, the slat ends taper to a nearly pointed or flat point at the casing surface, creating a smooth transition between the slat and the casing. This can reduce the risk of material accumulation or sharp edges and facilitate handling and cleaning of the transport protection device.

[0034] The tapered slat ends can help integrate the slats better into the casing or enable a particularly even force transfer between the slat and the casing. It is also conceivable that the tapered slat ends could increase the service life of the transport protection device by reducing stresses at the transition areas.

[0035] In another possible embodiment, the transport protection device can be designed as an insert for a pneumatic tube carrier. For example, it is conceivable for the device to be dimensioned such that it can be inserted into the interior of a pneumatic tube carrier in order to reliably protect objects transported therein from mechanical influences. It can be particularly advantageous if the outer slats of the transport protection device extend far enough outwards that the device is inserted into the carrier with an oversized fit, i.e. with a slight pre-tension, when inserted into the pneumatic tube carrier. This oversized design allows for secure, elastic fixation of the transport protection device within the pneumatic tube carrier, effectively preventing slipping or rattling during transport.The outer slats can be designed to flexibly adapt to the internal cross-section of the pneumatic tube carrier, ensuring reliable damping and securing for both round and polygonal or other geometries. The elastic design of the slats ensures that the transport protection device retains its shape and function even after repeated insertion and removal. Furthermore, the over-fitting can help ensure that the transport protection device always provides a secure fit, even with varying tolerances of the pneumatic tube carriers. In addition, the transport protection device can be adapted to different sizes and types of pneumatic tube carriers by varying the length, thickness, or material of the outer slats accordingly.

[0036] In a further possible embodiment, the transport protection device can consist of two separate parts. For example, it is conceivable that the device is divided into two sub-areas in the middle of its longitudinal axis, i.e. perpendicular to the longitudinal axis. This division can serve to facilitate production, but also handling, cleaning, or the insertion and removal of transported goods. The two parts of the transport protection device can be designed such that, once joined together, they form a form-fitting and stable unit. Optionally, the connection between the two parts can be realized using a tongue and groove system. With such a design, one part of the device has a groove, while the corresponding other part is provided with a matching tongue.By sliding or plugging the tongue and groove together, a secure yet detachable connection is created, allowing for easy assembly of the device. Alternatively, other connection solutions are also conceivable, such as snap connections, magnetic closures, screw connections, or adhesive bonding, provided they ensure reliable function.

[0037] In a second aspect, the present invention relates to an insert which is particularly intended for use as an insert for a transport protection device according to the first aspect. The insert consists of a flexible material, for example of thermoplastic polyurethane (TPU) or another suitable elastomeric plastic. The flexibility of the material enables the insert to adapt to different shapes and sizes of transported goods and to return to its original shape after deformation. This ensures reliable damping and effective protection of the transported goods against mechanical influences such as shocks or vibrations. The insert has a base area which serves as a basis for the arrangement of further functional elements. Lamellae are arranged on a first side of the base area.As an alternative to slats that extend in one direction, a plurality of raised elements arranged one behind the other can be used. For example, a row of spikes can replace one slat. These can be thin cones or cone-like structures where the base of the cone is on the surface and the cones are arranged in a row that replaces the slat, i.e. the cones are adjacent and spaced apart on the surface where, in the case of a slat, the slat is located. Instead of replacing the slat with spikes or spikes, the slats can also be segmented, interrupted or offset. The slats can also be lattice-shaped or consist of a series of bars.These slats can be designed in various shapes, such as straight, curved, wavy, or serrated, and serve to additionally secure the transported goods and protect them from vibrations. The slats can extend from the base towards the object to be protected, providing elastic support. The elastic design of the slats absorbs and dissipates the energy from shocks or vibrations, significantly reducing the risk of damage to the transported goods. The arrangement, shape, and number of slats can be flexibly adapted to specific requirements. For example, the slats can be arranged parallel to one another on the base. The base of the insert can be designed to fit precisely into the interior of a transport protection device, forming an additional protective layer.For example, the base surface is designed as the shell of a cylinder or a cylinder-like geometry. For example, the base surface can roughly form a cylinder or form a prism-like shell. Optionally, the insert can be designed so that it can be easily removed and reinserted to enable simple cleaning or quick replacement. The use of a flexible material for the insert also offers the advantage that the insert can be used multiple times without diminishing its protective effect. The combination of a flexible base surface and elastic lamellas thus represents a particularly effective solution for protecting sensitive transported goods.

[0038] In a further possible embodiment, it can be provided that the base area of ​​the insert is arranged concentrically around a first axis. With such a design, the base area can, for example, have a rotationally symmetrical shape, with the first axis preferably serving as the central longitudinal axis of the insert. This concentric arrangement makes it possible to align the slats so that they extend from the base area into the interior of the insert. It is conceivable that the slats in this embodiment are arranged radially or concentrically to the first axis and are oriented towards the center of the insert. This makes it possible to achieve uniform support and damping of the transported goods in use from all directions.The concentric arrangement of the base and the slats can be particularly advantageous when the insert is intended for cylindrical or rotationally symmetrical transport goods, as the slats can flexibly adapt to the contour of the object. Alternatively, the base of the insert can be arranged not exactly concentrically, but only in sections or segments around an imaginary axis in order to enable targeted adaptation to special transport goods or special requirements. In particular, a gap can be provided in the outer surface formed by the base of the insert, which gap preferably runs along the longitudinal direction. The orientation of the slats in the interior of the insert can be selected so that they offer optimal fixation and shock absorption for different object shapes.The design of the base area and the slats can be flexibly adapted to the specific application conditions. For example, the slats can be of different lengths, thicknesses, or depths to enable graduated damping or targeted fixation. Likewise, the slats can be arranged closer together or further apart in certain areas of the insert to ensure individual adaptation to the transported goods. Overall, a base area arranged concentrically around a first axis with slats extending into the interior offers a versatile option for further optimizing the protective effect and adaptability of the insert to various transport requirements.

[0039] In another possible embodiment, the insert can be designed to be transparent. This transparency can be achieved by selecting suitable plastics, such as transparent thermoplastic polyurethane or other translucent elastomers. The use of a transparent insert can offer various advantages. For example, the condition or position of the transported goods in the insert can be visually inspected at any time without having to remove or open the insert. This can be particularly advantageous for delicate or valuable items, as it makes it easier to check for damage or contamination. Alternatively, the transparency of the insert can help simplify the identification of the transported goods, for example when multiple inserts with different contents are used in a transport protection device.It is also possible to use the transparency to make markings, labels, or color coding visible on the transported goods, which supports allocation and handling in the logistics process. The option of implementing the insert transparently thus represents an additional option for further increasing the functionality and user-friendliness of the insert without compromising the protective effect or flexibility of the material.

[0040] In a further possible embodiment, it can be provided that the slats on the first side of the base area of ​​the insert are arranged parallel to a first axis. For example, it is conceivable for the slats to run in the longitudinal direction of the insert and thus extend along an imaginary axis, which is preferably designed as the central longitudinal axis of the insert. This parallel arrangement of the slats can contribute to the transported goods being supported evenly and being dampened particularly effectively during axial movements. Alternatively, the orientation of the slats can be selected so that they extend along the first axis, thereby enabling targeted guidance and fixing of the transported goods inside the insert. The slats of the insert can preferably be arranged parallel and in pairs on the base area.The parallel arrangement can be particularly advantageous when transporting elongated or rod-shaped objects, as the slats can flexibly adapt to the contours of the goods being transported and ensure secure storage. It is also possible for the slats to be arranged at different distances from one another or in several parallel rows to enable graduated damping or individual adaptation to different goods being transported. The design and alignment of the slats can be flexibly adapted to the specific requirements of the application. For example, the slats can be arranged closer together or further apart in certain areas to achieve targeted fixation or increased shock absorption.

[0041] In a further possible embodiment, the insert can be designed so that it can be rolled up or unrolled vertically in one direction. This means that the insert can be made, for example, from a flexible material which allows the entire component to be rolled up around an axis which runs perpendicular to the first axis of the insert. This property allows the insert to be stored or transported in a space-saving manner and can be returned to its original shape if necessary. It can be provided that the slats are directed into the interior of the rolled-up insert when the insert is rolled up. This ensures that the slats are protected inside the cylinder or prism when rolled up and are not damaged or come into contact with other objects.This arrangement can be particularly advantageous if the insert is to be used or transported multiple times without the slats becoming worn or deformed. Furthermore, it is conceivable for the rolled-up insert to take on a cylindrical or prism-shaped form. The shape in the rolled-up state can vary depending on the geometry of the base and the flexibility of the material. For example, a cylindrical rolled-up insert can be particularly well inserted into round containers or transport systems, while a prism-shaped design can offer advantages in terms of stackability or adaptation to square transport containers. Furthermore, it can be provided that the outer edges of the base of the insert, which run parallel to the first axis, lie opposite each other in the rolled-up state. This arrangement can help to give the rolled-up insert a particularly compact and stable shape.The opposite outer edges can touch or overlap when rolled up, providing additional fixation or stabilization of the rolled-up insert. The ability to roll up the insert opens up a wide range of possible applications, for example, for modular transport systems, flexible packaging solutions, or space-saving storage. The roll-up insert design can be flexibly adapted to specific requirements, for example by varying the material, slat geometry, or base dimensions.

[0042] In a further possible embodiment, the insert can be designed such that the slats are provided with stops or engagements at their longitudinal ends. For example, it is conceivable that these stops overlap in the projection along the longitudinal axis when the insert is rolled up. Such an overlap can provide additional fixation or stabilization of the insert in the rolled up state, thereby preventing the slats from unintentionally rolling up or shifting. Alternatively, it is possible for the slats to have engagements at their longitudinal ends and for stops to be arranged on the first side of the base of the insert at the level of the engagements, which engage with the engagements of the slats when rolled up. This design can help ensure that the insert remains dimensionally stable when rolled up and does not open accidentally.Furthermore, the insert can be provided with second slats arranged between the first slats, the ends of which serve as stops for the first slats. The second slats can be designed such that they extend less far into the interior of the insert than the first slats, although the ends of the second slats are exempt from this restriction and extend further into the interior, thus forming the stops. It is also possible for the second slats to have different geometries or material properties in order to specifically reinforce certain areas of the insert or to optimize the protective effect.The combination of first and second slats, wherein the second slats serve as a stop for the first slats, can be particularly advantageous if a defined limitation of the deformation of the first slats is desired or if the insert is to be rolled up and unrolled several times without the slats losing their shape.

[0043] In another possible embodiment, the insert can be manufactured using an additive manufacturing process, in particular 3D printing. The use of an additive process offers the possibility of realizing complex geometries and individual structures, such as slats, stops or special damping elements, in a single production step. It is conceivable that the use of 3D printing could allow the slats to be specifically adapted in terms of their shape, arrangement and material thickness to the respective requirements of the transported goods. For example, the wall thickness of the base area or the geometry of the slats can be varied locally in order to specifically reinforce certain areas or make them more flexible. Likewise, 3D printing can be used to directly integrate functional elements such as stops, interventions or special surface structures without the need for subsequent assembly.Alternatively, the additive manufacturing process can be used to produce the insert from different materials or with varying material properties. For example, certain areas of the insert can be made from a particularly flexible material, while other zones exhibit greater rigidity. Through the targeted selection and combination of materials within the additive process, the protective function of the insert can be further optimized. Furthermore, 3D printing enables the cost-effective production of even small batches or individual pieces. The high degree of design freedom offered by the additive process can be used to adapt the insert to specific requirements or the particular geometries of the transported goods.Optionally, the additive manufacturing process can also be used to equip the insert with specific markings, markings or individual adaptations.

[0044] A third aspect of the invention provides a method for producing an insert according to the second aspect, in which the insert is manufactured using an additive manufacturing process. For example, the additive process can be implemented as 3D printing. The insert can be made from a flexible material, such as thermoplastic polyurethane or another suitable plastic. The additive manufacturing process makes it possible to create complex geometries and individual structures, such as slats, stops, or special damping elements, in a single production step. It is conceivable that during 3D printing, the shape, arrangement, and material thickness of the slats can be specifically adapted to the respective requirements of the transported goods. For example, the wall thickness of the base area or the geometry of the slats can be varied locally in order to specifically reinforce certain areas or make them more flexible.Likewise, functional elements such as stops, interventions or special surface structures can be directly integrated using the additive process without the need for subsequent assembly. Alternatively, the additive manufacturing process can be used to produce the insert from different materials or with varying material properties. For example, certain areas of the insert can be made from a particularly flexible material, while other zones have greater rigidity. The protective function of the insert can be further optimized through the targeted selection and combination of materials within the additive process. Variable rigidity can also be achieved in additive manufacturing by varying the in-fill - usually, unless the strength requires it, the walls or surfaces of additively manufactured components are made of a special material.the geometries are not made solid, but merely partially filled. This reduces production time, energy consumption, weight, and material consumption. These cavities and their filling patterns can further influence stiffness and elasticity. The degree of filling (“in-fill”) is usually given as a percentage and varies from 100% (= solid) down to, for example, 15% (= very light with a lot of hollow space). This degree of filling naturally affects both the strength and stiffness of components. In addition, 3D printing enables the economical production of even small batches or individual one-off pieces. The high design freedom of the additive process can be used to adapt the application to special requirements or particular geometries of the transported goods.Optionally, the additive manufacturing process can also be used to equip the insert with specific markings, markings or individual adaptations.

[0045] Preferably, the insert is aligned during the additive manufacturing process so that the first longitudinal axis of the insert serves as the reference direction for the layer structure. This can be particularly advantageous when the lamellae are arranged parallel or concentrically to the first axis, as this allows for particularly precise and material-efficient manufacturing. This allows the insert to be manufactured without a support structure.

[0046] A fourth aspect of the invention relates to a method for producing a transport protection device according to the first aspect, in which the transport protection device is produced using an additive manufacturing process. For example, production can be carried out using a 3D printing process. The additive process makes it possible to realize complex geometries and individual structures, such as inner and outer slats, impact absorbers, or special damping elements, in a single manufacturing step. It is conceivable that the transport protection device is aligned during the additive manufacturing process so that certain axes or functional areas can be manufactured with particular precision. The design of the device can be flexibly adapted to different requirements, for example by varying the wall thickness, the slat geometry, or the material distribution.The additive manufacturing process also offers the possibility of integrating functional elements such as handles, plug-in connections, or articulated joints directly into the transport protection device without the need for subsequent assembly. Likewise, different areas of the device can be manufactured from different materials or with varying material properties, or even with variable wall thicknesses or filler levels, in order to specifically reinforce certain zones or make them more flexible. Alternatively, the transport protection device can be manufactured using conventional manufacturing processes, such as injection molding. The same applies to the application. The selection of the manufacturing process can be flexibly adapted to the respective requirements, the desired quantity, or the specific material properties.

[0047] In another possible embodiment, the transport protection device is positioned during the additive manufacturing process so that the layers of the printing material are built up in the direction of the longitudinal axis. This approach can help ensure that the device can be printed without a support structure. Optionally, the orientation of the printing process can be selected along the longitudinal axis to enable particularly precise formation of longitudinally oriented structures such as inner and outer slats, impact absorbers, or reinforcing ribs. This printing direction can also be advantageous if the device is intended for applications in which directed loading or movement occurs along the longitudinal axis, for example when used in pneumatic tube systems or automated conveyor systems.

[0048] In another possible embodiment, a transport protection device can be manufactured using an additive manufacturing process, in particular by 3D printing, in such a way that the device is manufactured in two separate parts. It can be provided that each of the two parts is constructed along the longitudinal axis, starting from one of the two ends, for example the impact absorbers, of the transport protection device. This procedure makes it possible, for example, to print the two halves of the device independently of one another and then connect them to one another. Separating the device into two printed parts can also facilitate the production of complex geometries without a support structure, particularly if undercuts, internal lamellar structures, or special damping elements are provided.After the printing process, the two parts can be joined together, for example by a positive connection such as a tongue and groove design, by snap connections or by adhesive bonding. By printing the two halves separately, the device can be easily assembled after the printing process, thereby achieving a high degree of flexibility in terms of size and geometry. It is also conceivable that the division of the device along the longitudinal axis could also be used to facilitate cleaning, maintenance or the replacement of individual components. The connection between the two parts can be designed to enable a removable or permanent connection, depending on the requirements of the respective area of ​​application.The design of the manufacturing process with two separately printed parts thus offers a wide range of options for adapting the transport protection device to different technical and functional requirements.

[0049] In the embodiments described above, the lamellae can be replaced by lamella segments in a further embodiment. Furthermore, the lamellae can be replaced by spikes / domes. These can be cylindrical, pyramidal, or conical, for example. In particular, if spikes or other alternatives are used instead of the lamellae, these do not necessarily have to be arranged or lined up along a line that corresponds, for example, to the line on which the lamella is arranged on the surface. In such an embodiment, the spikes can follow a pattern, be arranged helically, chaotically, or in some other way. Likewise, interrupted lamella segments or multiple lamella segments arranged randomly or in a pattern can be used. It goes without saying that the lamellae can also be provided with spikes, lamella segments, or similar.can be combined, or that only the inner, outer, or insert slats are replaced or combined with them. It is also intended that only one type of insert slat is replaced or combined.

[0050] In particular, the outwardly directed fins can be omitted from the base body and the cover or can be replaced by other geometries, as described above, among others but not limited to.

[0051] The invention can be implemented even more generally by using multiple motion-inhibiting or shock-absorbing components in a regular or random arrangement instead of the outer slats, inner slats, or insert slats. The motion-inhibiting or shock-absorbing components are elastic and can convert kinetic or acceleration energy into deformation energy. Furthermore, the motion-inhibiting or shock-absorbing components are designed in such a way that they can, for example, space objects away from the surface on which they are arranged, thus acting as spacers.An object resting against one or more motion-restraining or shock-absorbing components can transfer kinetic or acceleration energy to the motion-restraining or shock-absorbing components when forces due to the object's acceleration act on the motion-restraining or shock-absorbing components, and the corresponding energy is converted into deformation energy. For example, if the transported object is enclosed or held by the motion-restraining and / or shock-absorbing components, an externally acting acceleration can be converted into deformation of the motion-restraining and / or shock-absorbing components, so that the acceleration is not fully transmitted to the transported object.

[0052] Fig. 1 shows a transport protection device 1 according to one aspect of the invention. The transport protection device has a cylindrical casing 2. The open ends of the casing 2 are closed by cylindrical shock or impact absorbers 4. Furthermore, outer lamellae 3 are arranged on the surface of the casing 3 in the longitudinal direction of the cylindrical casing. The outer lamellae 3 are arranged concentrically in pairs on the casing surface 3. Each pair of lamellae 3 is arranged in a V-shape and is connected to the casing 2 via a web 6. The web 6 runs parallel to the longitudinal axis of the casing 2. The outer lamellae 3 extend outwards from the surface of the casing 2. In particular, the outer lamellae of a pair of lamellae arranged on a web 6 extend spread apart, i.e. the distance between the lamellae increases with increasing distance from the casing surface.In this case, the slats do not run radially outwards, but in a V-shape, whereby in an alternative embodiment, the paired arrangement can be dispensed with and / or the slats can run radially or diagonally outwards. The outer slats 3 can have one or more recesses 7 in the middle or at another position in the longitudinal direction. The recess 7 divides the outer slat into two slat parts arranged on the web 6. Each outer slat pair thus has four slat parts. The slats or slat parts 3 are tapered at their ends in the longitudinal direction. In other words, the slats are chamfered at their ends and run towards the casing surface / taper down to the surface of the web 6 via which the slats are connected to the casing 2. The shock or impact absorbers 4 have a recessed handle 8. The transport protection device is made of an elastic material, e.g.Made of thermoplastic polyurethane (TPU). The transport protection device 1 designed in this way allows the conversion of kinetic energy into (elastic) deformation energy in all three spatial axes. This is ensured either by deformation of the outer slats 3 or by deformation of the impact absorbers 4 at both ends of the transport protection device 1. The outer slats 3 provide the transport protection device 1 with additional stability, allowing it to absorb kinetic energy during positive and negative accelerations.

[0053] The load or transported goods are arranged inside the transport protection device 1 and protected from strong acceleration by the slats 3 and the impact absorbers 4. The transport protection device 1 can be used in particular in a pneumatic tube carrier. For example, the transport protection device 1 can be used in a pneumatic tube carrier from Swisslog. The slats 3 are designed such that the diameter of the transport protection device 1 is slightly larger than the inner diameter of the pneumatic tube carrier. The transport protection device 1 is oversized in terms of its diameter compared to the pneumatic tube carrier. As a result, the slats 3 are pre-tensioned when the transport protection device 1 is used in a pneumatic tube carrier.This leads to an elastic mounting of the transport protection device within the pneumatic tube carrier, the outer slats 3 and also the impact damper 4 can continue to absorb kinetic or acceleration energy through elastic deformation and thus protect transported goods in the interior of the transport protection device 1.

[0054] The use of TPU as a material ensures that the transport protection device 1 is reusable and media-resistant, meaning that the transport protection device 1 can be cleaned with cleaning agents without damaging the transport protection device. When used in a pneumatic tube system in a medical facility, the transport protection device 1 can be disinfected, for example, by wiping, in a dishwasher, in an automated process, or in an autoclave. This is ensured in particular by the thermal stability of TPU up to 110°C.

[0055] The connection of the outer slats 3 of the transport protection device 1 pre-tensioned in the pneumatic tube carrier with the impact absorbers 4 ensures improved absorption of acceleration peaks, such as in free fall or in the event of an impact at the end of the journey, since the energy can also be absorbed by the connected element.

[0056] Furthermore, a marking 5 can be applied to the casing surface 3 and / or to one or both of the handles 8. The marking can be, for example, a label, a barcode, a QR code, or an RFID tag. This allows for documentation, control, and / or tracking of the transport route and the transported goods.

[0057] Furthermore, the casing 3 can have a cover 9 (not shown in the figure), which is movably connected to the casing and replaces part of the casing. The structure of the cover corresponds to that of the casing piece that is replaced by the cover. By opening the cover, a user can arrange transported goods inside. The casing 3 without the cover forms a housing shell of the transport protection device 1.

[0058] The transport protection device 1 can be designed in two parts, so that the transport protection device is divided transversely to the longitudinal direction in the cylinder center or at another position of the housing shell 3. The two parts can be mechanically connected, e.g., by means of a tongue and groove.

[0059] The transport protection device 1 can be manufactured using a 3D printing process. The transport protection device 1 is printed, in particular, in the longitudinal direction. In the two-part version, both parts are printed in the longitudinal direction, with printing beginning at the position of the impact absorber 4. This allows the transport protection device 1 to be printed without a support structure, saving material.

[0060] Fig. Figure 2 shows the transport protection device 1 with the cover 9 open. Inner, elastic lamellae 11 are arranged inside the transport protection device. The inner lamellae 11 are arranged on the inside of the housing shell 3, parallel to the longitudinal direction of the shell and the transport protection device 1. The inner lamellae are firmly connected, in particular directly, to the shock and impact absorbers 4. This arrangement stabilizes the lamellae, preventing them from being "simply pushed to the side" under load.

[0061] The inner lamellae 11 are preferably arranged in pairs on the inside of the casing 3. The inner lamellae arranged in pairs extend into the interior of the transport protection device; it is understood that this also applies to the inner lamellae of the cover 9 in the closed state. In the closed state, the housing casing and cover 9 form a casing 3 on which the inner lamellae 11 are arranged. The inner lamellae 11 do not extend radially inwards to the central axis of the transport protection device 1. In embodiments not shown, the lamellae extend radially inwards. The inner lamellae 11 arranged in pairs extend into the interior of the transport protection device 1, wherein the distance between the inner lamellae 11 increases with increasing distance from the inside of the casing in the direction of the longitudinal axis of the transport protection device 1.

[0062] The transported goods can be arranged inside the transport protection device. The inner plates act as additional shock absorbers, absorbing energy through deformation. The absorption mechanism is essentially the same as that of the outer plates 3. A shock or sudden acceleration causes the transported goods to move, which is dampened by the elasticity of the inner plates. The plates, in turn, are firmly connected to the impact absorbers 4, allowing the energy to be optimally distributed within the system. This dampens acceleration peaks from all three spatial directions.

[0063] The cover 9 may correspond to a part of the cylindrical shell 2, in the Fig. 2, the cover 9 is a segment of the cylinder.

[0064] Fig. 3 shows an insert 12 arranged in the interior of the transport protection device 1. The insert 12 can, for example, replace bubble wrap or other additional packaging material. The insert 12 can accommodate different container sizes, for example in terms of length and size, in pockets provided for this purpose. Several inserts 12 can be inserted next to one another or one behind the other in the transport protection device 1. The insert 12 rests with an outer surface at least partially or completely against the inner slats 11 of the transport protection device. As a result, the insert is protected from impacts by the outer slats 3 and the inner slats 11 of the transport protection device, among other things in combination with the impact absorbers 4. The outer slats dampen the forces introduced from the outside, and the inner slats support energy absorption by supporting the insert and the transported goods contained therein in a flexible, energy-damping manner.The insert can also represent an additional damping element and is described further below.

[0065] Fig. 4 a shows a side view of the transport protection device 1. The outer slats 3 are arranged in pairs and in a V-shape on the outer surface of the cylindrical casing 2 of the transport protection device 1 parallel to the longitudinal axis.

[0066] Fig. Figure 4b shows a top view of one end of the cylindrical transport protection device 1. The outer blades 3 extend outward, diverging in pairs in a V-shape. A marking 5 can be applied to a handle 8 connected to the impact absorber 4. The outer blades 3 are connected to the outer shell surface via a web 6. The web 6 can be part of the shell surface. The shell surface is formed by the shell housing and cover.

[0067] Fig. Figure 4c shows a sectional view transverse to the longitudinal axis through the transport protection device. The outer lamellas 3 are arranged on the outer surface of the casing 2, as shown in Fig. 4b. The inner lamellae 11 are arranged on the inner surface of the casing 2. The inner lamellae 11 extend in pairs, diverging in a V-shape, i.e. the distance between the inner lamellae 11 of a lamella pair increases with increasing distance from the inner surface of the casing. The inner lamellae 11 preferably extend more than half the inner radius of the cylindrical casing 2 into the interior. This allows the lamellae to deform more greatly before the deformation is stopped by the casing surface; likewise, a deeper lamella can generally deform more greatly and absorb more deformation energy. The insert, not shown in the figure, can be arranged inside in the area delimited by the inner lamellae.

[0068] Fig. 5a shows a view of a cover 9. The cover 9 has, for example, the shape of a segment of the outer surface of a cylinder. The outer lamellae 3 are arranged in pairs on the outer surface of the cover 9. The outer lamellae 3 correspond to the outer lamellae 3 on the housing of the transport protection device, wherein the housing is the transport protection device without the cover 9. The inner lamellae 11 are arranged in pairs on the inner surface of the cover 9. Inside and outside refers here to the state in which the transport protection device is closed with the cover. The inner lamellae 11 can pass through the interior space formed by extending the circular segment formed by the cover along the longitudinal axis of the cover, i.e. the lamellae 11 extend from the inner surface of the cover 9 to the opposite side of the circular segment or beyond.

[0069] Fig. 5b shows a section through the cover 9 transverse to the longitudinal direction of the cover 9. The slats described above are shown. The inner slats 11 protrude in pairs in a V-shape into the interior. The web 6, on whose surface the outer slats 3 are arranged, is part of the cover and is U-shaped or circularly arced. The circular-arc-shaped web 6 is integrated into the cover 9. The inner slats 11 arranged in pairs are each arranged at one end of the circular web 6 on the inside of the cover. The circular-arc-shaped web 6 and the inner slats 11 form the shape of a U, the legs of which diverge, i.e. the distance between the legs increases with increasing distance from the circular part of the U.

[0070] One long side of the cover 9 further has a groove 13 into which a spring, which is part of the housing of the transport protection device 1, can engage, so that the groove 13 and spring form a movable mechanical connection, whereby the cover can be rotated about the longitudinal axis through the center of a circular spherical head of the spring. Alternatively, a film hinge is located next to the groove. This allows the cover 9 of the housing of the transport protection device 1 to be opened and closed. The cover is firmly connected to the housing by the groove 13 and spring. A film hinge is arranged next to the groove. A film hinge allows mobility by weakening the material. The material of the housing is therefore weakened parallel to the groove, so that the cover, including the groove and spring, can move around the longitudinal axis of the weakened area.

[0071] Fig. 6 shows an insert 12 that can be inserted into the transport protection device. The insert 12 has a base surface 14. When the insert 12 is inserted into the transport protection device, the base surface 14 borders on the inward-facing ends of the inner lamellae 11. As a result, the insert 12 is flexibly supported by the inner lamellae 11. By deformation, the inner lamellae can dampen / protect the insert 12 against impacts. The insert 12 can be larger than the free interior space defined by the inner lamellae 11, so that the insert prestresses the inner lamellae 11 when the insert is inserted into the transport protection device. The base surface 14 is arranged approximately on a cylindrical shell. Base surface 14 has a first outer side that approximately corresponds to the outer side of the cylinder shell. The cylinder shell formed by the base surface 14 has a gap 15 in the longitudinal direction. The gap 15 is delimited by two edges 21 of the base surface.The insert 12 is made of a flexible material such as TPU and therefore has the same advantages as the transport protection device based on TPU. The flexible material of the insert 12 makes the gap 15 flexible. When force is applied to the outside of the base area 14, i.e. to the side of the approximately cylindrical or prima-shaped insert 12 that faces outwards, the gap 15 can become larger or smaller. If the gap 15 becomes smaller, the diameter of the insert 12 decreases. If the gap 15 becomes larger, the diameter of the insert 12 increases. The gap 15 can, for example, be compressed so that the diameter decreases enough for the insert to be inserted into the interior of the transport protection device 1. The insert 12 then relaxes, whereby the diameter of the insert increases and a force-fitting connection to the inner slats 11 of the transport protection device 1 is created.

[0072] The inner side of the base surface 14 of the insert 12, which is arranged cylindrically, has slats 16. These slats are referred to below as insert slats 16.

[0073] Fig. 7 a and b show sectional views of the insert 12. Fig. 7a shows a longitudinal section and Fig.7b shows a section transverse to the longitudinal direction. The base surface 14 of the insert 12 has insert lamellae 16 arranged on its inner side, which run parallel to the longitudinal direction of the insert 12. The insert lamellae 16 extend into the interior of the insert 12 and form pockets 17. The pockets 17 can accommodate transported goods, for example containers or ampoules with sensitive goods, such as samples or medications. The insert lamellae 16 do not extend completely to the central axis of the insert and form a free space 18 in the center of the insert 12. Containers or transported goods can also be arranged in this free space 18. In particular, the containers can be larger than the free space and thus, when arranged therein, at least partially prestress the insert lamellae. Similarly, the containers arranged in the pockets 17 can be larger than the pocket 17 in a relaxed insert.Inserting the oversized container into the pocket 17 deforms the slats and pre-tensions them. This pre-tension holds the container in its position in the pocket.

[0074] The insert slats 16 are again arranged in pairs. There are two types of slat pairs. The first type of insert slat pair 16a is U-shaped overall, with the two slats 16a forming the legs of the U, and the part of the base of the insert that connects the two insert slats 16a being circular and forming the circular part of the U. The slats of the first type 16a extend into the interior of the insert 12 and have an engagement 19 at their upper and lower ends relative to the longitudinal axis of the slat. This engagement allows a stop element of the insert slats 16b of the second type to engage in this engagement 19, so that, in the projection along the longitudinal axis, a slat of the first type 16a and a slat of the second type 16b overlap.The slats 16a, 16b are thus hooked or interlocked with each other and prevent the transported goods from escaping and sliding through the pockets 17 in the longitudinal direction.

[0075] The second insert lamella type 16b has stop elements 20 at its ends, which extend further into the interior of the insert 12 than the remaining part of the lamella 16b. A pair of insert lamellas of the second type 16 can be connected at their ends or stop elements 20 by a web. The further part of the lamella 16b, which connects the two stops in the longitudinal direction, extends less far into the interior than the insert lamella of the first type 16a. The stop element 20 extends far enough into the interior that it can engage the engagement 19 of the first lamella type. Thus, two lamellas of the first and second types 16a, 16b are arranged interlaced, with the stop element 20 of an insert lamella of the second type 16b engaging the engagement 19 of the insert lamella of the first type 16a.

[0076] The insert 12 can preferably be manufactured by 3D printing, with printing taking place in the longitudinal direction of the insert 12. The geometry allows the insert to be printed without a support structure. The insert additionally protects sensitive transported goods arranged in the pockets 17 or the interior 18 against impacts, e.g., due to strong acceleration. The slatted structure ensures that energy can be dissipated through deformation. In this sense, the damping mechanism corresponds to the damping already provided by the slats 3, 11 of the transport protection device 1, with the geometry of the slats additionally securing the transported goods against slipping along the longitudinal axis.

[0077] The transport protection device 1 in combination with the insert 12 is particularly advantageous as an insert in a pneumatic tube carrier used in medical facilities. For example, samples or ampoules containing medication can be arranged in the pockets 17 and the interior 18 of the insert. According to the invention, this transported material is shock-protected in three ways: firstly by the outer lamellae and the impact absorbers, secondly by the inner lamellae 11, and thirdly by the insert 12. The damping is achieved in particular by absorbing energy through deformation of the lamella structure. Through the use of TPU and the special geometry, the transport protection device 1 and the insert 12 can be manufactured by 3D printing without the need for material for support structures.The transport protection device prevents the spread of germs in medical facilities, as unsuitable protective packaging that is difficult or impossible to disinfect, such as bubble wrap, foam, cardboard, etc., can be dispensed with.

[0078] Furthermore, the transport protection device 1 and the insert 12 are media-resistant, i.e. they can be cleaned with approved cleaning agents for medical use. For example, the parts can be sterilized by automatic sterilization, wipe disinfection or in a suitable dishwasher. The shock-absorbing properties protect the transported goods from excessive vibration, which is particularly advantageous when used in pneumatic tube systems. The geometry can be adapted to commercially available pneumatic tube carriers, so neither the outer surface of the transport protection device nor the base surface of the insert needs to be cylindrical. The surfaces can also be rectangular or prism-shaped. The length by which the slats protrude outwards or inwards is adapted according to the geometry. For example, the insert can also be rectangular with several layers and inserted into a rectangular box.The provided marking capability allows the transport of transported goods to be documented and tracked, which is also advantageous in medical facilities with corresponding documentation requirements. The elasticity of the slats also allows for the use of different container sizes. The lid 9 and the housing 2 of the transport protection device 1 can be colored in two different ways. This advantageously allows the position of the transport protection device to be identified, allowing the transported goods to be stored and removed in a safe position.
