    Description: The invention relates to a transport container having an integrated device for monitoring compliance with a predetermined temperature range inside the container, e.g. during shipment of temperature-sensitive goods (such as medicines, food or other refrigerated goods) in the transport container.
    When storing temperature sensitive goods (such as medicines or foodstuffs), care must be taken that the storage temperature is always within a predetermined temperature range or range, e.g. does not exceed a predetermined maximum temperature and / or does not fall below a predetermined minimum temperature. When transporting or transporting temperature-sensitive refrigerated goods, care must be taken to ensure that the specified temperature range is maintained throughout, with e.g. When shipping medication or food, maintaining a continuous cold chain is required.
    There are different devices for monitoring compliance with a predetermined target temperature range during the transport temperature-sensitive goods known. Thus, e.g. WO 2006/015961 A2 a time-temperature indicator based on a temperature-dependent chemical reaction. As another example, DE 4 139 728 C1 describes an electronic transport monitoring device which may include a temperature sensor.
    The invention provides a transport container is provided with a cost-effective and versatile system for monitoring the temperature prevailing in a transport container, by means of which the temperature status of the transported material can be determined without much additional time and the entire temperature history traversed during the transport is traceable.
    According to one aspect of the invention, a transport container is provided. The transport container has a plurality of boundary walls, wherein one of these boundary walls has a receptacle or is formed with a receptacle. In the receptacle, a monitoring device with a temperature sensor connection terminal, a data logger and a display device is included. The monitoring device is thus integrated in the transport container; wherein the receptacle may in particular be designed such that the monitoring device is removably received or receivable in the same. The transport container is provided in particular as a reusable transport container, wherein the container is provided together with the monitoring device for repeated use.
    The temperature sensor connection terminal is configured to electrically couple a temperature sensor element disposed inside the transport container to the monitoring device to form a releasable connection (e.g., a detachable connector); wherein the sensor element allows detecting the temperature present in the interior of the transport container. The temperature sensor element is a temperature sensor or sensor, i. an electronic component, by means of which a temperature is converted into a varying electrical size with the same. The temperature sensor element may e.g. a thermistor (e.g., a PTIOO sensor element), a semiconductor temperature sensor, or a thermocouple.
    The temperature sensor element is coupled by means of a connecting element to form a detachable connection to the temperature sensor connection terminal of the monitoring device, wherein the connecting element, e.g. may be provided as part of the temperature sensor element or coupled with the same. The connecting element of the temperature sensor element and the temperature sensor connection terminal of the monitoring device are mutually suitably designed such that they can be releasably connected together to form a temperature signal interface. The interface formed by the connection element and the temperature sensor connection terminal enables the transmission of the temperature signals generated by the temperature sensor element from the temperature sensor element to the monitoring device.
    The data logger is connected to the temperature sensor connection terminal (ie is in data or signal connection with the temperature sensor connection terminal), so that in the presence of a connection between the connection element of the temperature sensor and the temperature sensor connection terminal generated by the temperature sensor element temperature signals via the interface can be transferred to the datalogger. The connection element and the temperature sensor connection terminal may be e.g. Complementary parts of a plug connection, wherein preferably arranged on the temperature sensor connecting element is designed as a plug and arranged on the monitoring device temperature sensor connection terminal as a socket. However, it may e.g. Also be provided to form the connecting element as a coupling and the temperature sensor connection terminal as a built-in connector.
    It may e.g. be provided to the temperature sensor element by means of an elongate sensor connection element (i.e., the longitudinal dimension of the sensor connection element is substantially greater than the transverse dimensions) to couple to the monitoring device, wherein such a sensor connection element comprises the temperature sensor element, the connecting element and one or more signal lines. The sensor connection element may e.g. be formed strand-shaped or strip-shaped and is hereinafter also referred to as a sensor strip; wherein the sensor strip has two longitudinal ends. The temperature sensor element may be arranged on one of the two longitudinal ends of the sensor strip, wherein the connecting element is arranged on the other of the two longitudinal ends of the sensor strip.
    Strip is arranged. The sensor strip also includes one or more signal lines extending between the temperature sensing element and the connector, i. electrically conductive connection lines (e.g., metal lines) for signal transmission connecting the temperature sensing element to the connector.
    The sensor strip may e.g. a flexible deformable sensor support element made of an electrically insulating material (e.g., paper or plastic); wherein the temperature sensor element, the connecting element and the signal line (s) can be arranged on the sensor carrier element or embedded in the same.
    In particular, it can be provided that the temperature sensor element and / or the signal lines are embedded in such a sensor carrier element, whereby they are e.g. protected against mechanical damage and moisture. The connecting element arranged on the sensor strip and the temperature sensor connecting terminal arranged on the monitoring device are designed to be detachably connected to one another in such a way that they can be releasably connected together to form a temperature signal interface. By means of the sensor strip, the temperature sensor element can be arranged projecting into the interior of the transport container at a distance from the boundary wall formed with the receptacle. Accordingly, the sensor strip may be e.g. be formed with a length of at least 5 cm, preferably with a length of at least 15 cm.
    The monitoring device is designed in such a way (eg by means of a suitably programmed microprocessor, which may be provided either as part of the data logger or separately to the same) that detected in the presence of a signal connection to the temperature sensor element by means of the same temporally successive present temperature readings and on a data memory of the data logger are stored as temperature data (eg together with the respectively associated acquisition time). The monitoring device may e.g. be designed such that the temperature measured values are recorded and stored in time continuously or at predetermined (for example, constant) measurement intervals.
    The display device may e.g. an LCD display (i.e., a liquid crystal display), an OLED display (i.e., an organic light emitting diode based display), or an e-paper display (i.e., a so-called electronic paper based display). In particular, the display device may be a bistable display device (e.g., a bistable LCD) or an electrophoretic display device; In this case, a power supply is required only for a change of the information displayed by the display. In addition, the display device is preferably a passive (not self-luminous) display, which works by reflection of light incident thereon.
    The recording and the monitoring device are designed such that when recorded in the recording monitoring device, the display device from outside the transport container is optically accessible and the temperature sensor connection port is physically accessible from inside the transport container (so that when arranged inside the container temperature sensor element the same can be connected to the monitoring device).
    The monitoring device is set up or configured in such a way that-with the temperature sensor element coupled-the display device (for example by means of the microprocessor) is actuated based on the temperature measured values detected by means of the coupled temperature sensor element.
    The monitoring device is configured such that by the display device in human-readable form (eg as plain text and / or pictogram) and / or as a machine-readable code (eg as a QR code, from the English for quick-response code) Information regarding the recorded temperature history can be displayed. The use of QR code has the particular advantage of a high data density in conjunction with a high fault tolerance.
    The monitoring device may e.g. be configured such that the display means in human readable form indicates whether or not the temperature inside the transport container has always been within a predetermined target temperature range (i.e., whether all detected temperature values are within the target temperature range or not); to indicate whether a temperature limit violation occurred or not. Thereby, e.g. be checked by a person charged with the transport (for example, a postman) or a recipient of the transport consignment by reading the display with little time, whether the specified temperature conditions for each cargo were respected. In addition, e.g. be provided that the last detected temperature, the detected maximum temperature, the detected minimum temperature, the entire detected temperature profile and / or the receiver name or other receiver data are displayed by the display device.
    Alternatively or additionally, it may be provided that the display device displays the temperature history or the entire recorded temporal temperature profile as a machine-readable code, e.g. as a QR code. Such a machine-readable code may e.g. be read optically by means of a scanner, e.g. at the beginning of the transport or when handing over the transport consignment to a receiver or intermediate receiver, the temperature history present at the time of transfer also being detected electronically by means of the scanner and e.g. can be electronically transmitted to a central data evaluation and further evaluated there and / or stored for verification purposes. The temperature history may e.g. include all recorded temperature values including the time of their acquisition. In addition, e.g. be provided by means of such a QR code, the highest and / or lowest detected temperature, the number of transgressions of a predetermined threshold temperature or threshold temperature (eg maximum temperature), the duration of exceeding a predetermined threshold temperature, the internal system time (eg in time intervals of eg 5 minutes, to be compared with an external system), and / or to encode an identification number identifying the monitoring device or the program.
    The updating of the information displayed by the display device may be e.g. timed, the display being e.g. is regularly updated at regular intervals. However, it may also be provided that the updating of the information displayed by the display device is event-controlled, the display being e.g. is updated only when a predetermined event occurs (e.g., a temperature limit violation).
    Not all data collected and stored by the monitoring device must also be displayed on the display. In particular, it can be provided that all the data recorded internally (such as, for example, the complete temperature measurement series since the activation) are recorded and stored, but the display is updated only at predetermined times and / or events. Furthermore, the monitoring device may comprise further sensors (for example a temperature sensor for detecting the ambient temperature outside the transport container, an acceleration sensor, a position sensor and / or a moisture sensor) and for detecting and storing the data detected by these sensors together with the associated detection times; in addition, the battery status can be logged. In addition, the monitoring device can have a real-time clock for exact time recording.
    It can also be provided that the monitoring device is designed such that the display device has or enable multiple information levels, wherein in the presence of each level different information from the display device are displayed, and wherein the display, for example. can be changed or switched between these levels by means of a switch arranged on the monitoring device. The representation of the information corresponding to a respective level on the display device may e.g. by means of a corresponding activation of the display device by the monitoring device (for example by the microprocessor of the monitoring device). Thus, e.g. be provided that in the presence of a first information level of the display device, the postal data of the recipient and the temperature-relevant information are displayed, and that are displayed in the presence of a second information level of the display device information of the sender to the recipient in encrypted form. This encrypted information may e.g. receiver side (electronic or optical) are read out and based on a receipt confirmation generated and transmitted electronically to the sender.
    When using such a transport container to be monitored temperature-sensitive Good is introduced into the same and transported to coupled to the monitoring device temperature sensor element to a destination; wherein by the monitoring device at the location of the temperature sensor element, that is, in the interior of the transport container, present temperature and the traversed during the transport temperature history can be detected.
    By the temperature sensor connection terminal for releasably connecting a temperature sensor is formed to the monitoring device, the temperature sensor connected to the monitoring device can be easily replaced. In particular, to reliably ensure compliance with a predetermined target temperature range, it may be necessary to detect the temperature in a near-center region of the interior of the container rather than an edge region near a boundary wall of the container, the temperature sensor projecting into the interior space must be designed and thus exposed to increased mechanical stress by interaction with the cargo, whereby a repeated replacement of the temperature sensor may be required. In addition, different temperature-sensitive goods may require compliance with different target temperature ranges - and thus the use of different temperature sensors - require. By allowing an uncomplicated replacement of the temperature sensor element, a versatile and reliable temperature monitoring can thus be made possible.
    In addition mass-effective temperature monitoring systems must be cost-effectively feasible despite high technical requirements, the costs in particular by the cost of the components of the monitoring system and the additional time caused by the monitoring system (read, make decision regarding the presence of a temperature limit violation, etc.) are caused , By the temperature sensor can be easily separated from the monitoring device and the monitoring device (including the container) can be used several times, the cost per transport process for the components of the monitoring system costs can be kept low (in particular because temperature sensors are available relatively inexpensive, whereas the components of Monitoring device on the other hand are much more expensive). By the display information with respect to the passed temperature history can be displayed in human-readable and machine-readable form, upon delivery of the transport container from both the transferor and the receiving without a great deal of time compliance with the required temperature conditions are checked, in addition to the temperature history (eg by means of can be electronically recorded and further processed centrally by transport companies used optical hand scanner). By means of the machine-readable code display, the entire temperature history can also be optically read out during machine operation.
    According to one embodiment, the receptacle is designed such that the monitoring device is arranged in the interior of the transport container on the boundary wall, wherein the boundary wall has a transparent portion.
    Accordingly, the receptacle and the monitoring device are designed such that, when recorded in the recording monitoring device, the monitoring device is arranged on an inner side of the boundary wall, that the display device is arranged on the transparent portion and thus from outside the transport container through the transparent portion the boundary wall is optically accessible. The transparent portion of the boundary wall thus functions as a viewing window for reading out the display device and can e.g. be inserted by injection molding in the boundary wall viewing window. According to this embodiment, the entire monitoring device is located inside the transport container, wherein in particular for connecting the temperature sensor element to the monitoring device formed in the boundary wall passage opening or aperture is not required and thus no penetration of contaminants through such a through hole is possible.
    According to another embodiment, the receptacle is formed such that the monitoring device is arranged outside the transport container on the boundary wall, wherein the boundary wall in the region of the receptacle or the temperature sensor connection terminal has a leading into the interior of the transport container through-opening.
    Accordingly, the receptacle and the monitoring device are designed such that, in the recording device accommodated monitoring device, the monitoring device is arranged on an outer side of the boundary wall, that the temperature sensor connection terminal from a position in the interior of the transport container through the through hole formed in the boundary wall is physically accessible, so that a arranged in the interior of the transport container temperature sensor can be coupled by means of a through the passage opening extending therethrough sensor or attachment member to the temperature sensor connection terminal.
    According to this embodiment, the monitoring device is easily accessible from outside the transport container and can e.g. be separated from the container without opening the same.
    It can be provided in particular to form the receptacle formed on the outside of the transport container receiving trough so that when recorded in the receiving trough monitoring device, the edge portions of the monitoring device (substantially) flush and gap-free connect to the adjoining the receiving trough portions of the boundary wall ie the monitoring device is (substantially) snugly received in the receiving trough. It can e.g. be provided to form the monitoring device with a cuboid shape, wherein the dimensions of the receiving well correspond to the cuboid dimensions of the monitoring device.
    Further, a (at least partially) transparent film may be provided, which is arranged such that it spans and is covered by the receiving trough together with the recorded therein monitoring device. The foil may e.g. may be secured to the boundary wall by means of a self-adhesive adhesive portion provided in its edge regions, and may e.g. be printed with additional information.
    According to one embodiment, the receptacle is formed integrally with the boundary wall, i. the boundary wall and the receptacle are formed as a single component, e.g. as an injection-molded component.
    According to one embodiment, the boundary wall having the receptacle, part of a closure lid of the transport container. Accordingly, the transport container has a closure lid which is provided for opening and closing the transport container, wherein the closure lid has the receptacle for receiving the monitoring device. The transport container may e.g. a lower shell having a bottom wall and side walls and a closure lid for closing the lower shell. By forming the receptacles in the closure cap, e.g. Existing transport container to be used with replacement of the previous cover against a cap with an integrated monitoring device.
    However, it may also be provided that the boundary wall having the receptacle is part of a side wall of the transport container. This can offer the advantage of easier readability of the display device with several stacked transport containers.
    According to one embodiment, the monitoring device is designed such that it is activated by means of coupling the temperature sensor element to the temperature signal interface; that is, by connecting the temperature sensor side connector to the monitor side temperature sensor connecting terminal, the temperature detection, temperature value storage, and temperature related information display are started by the display device. Alternatively or additionally, the monitoring device may be designed such that it is deactivated by disconnecting the temperature sensor element from the temperature signal interface; that is, by disconnecting the temperature sensor element, the temperature detection, temperature value storage and optionally also the display of the temperature-related information is terminated. According to this embodiment, the beginning and end of the temperature detection can be realized in a simple and time-effective manner.
    The temperature sensor element may e.g. be separated from the monitoring device by the detachable connection between the connecting element of the temperature sensor element and the temperature sensor connection terminal of the monitoring device is disconnected or dissolved.
    In the event that the temperature sensor element is coupled by means of the sensor strip described above, but can also be provided that the sensor strip has a predetermined separation point for severing the sensor strip at a predetermined separation position transverse to its longitudinal direction. The predetermined breaking point, which is preferably arranged at a position between the connecting element and the temperature sensor element, may e.g. be designed as a predetermined breaking point or as Sollrissstelle and e.g. be formed by a weakening portion of the sensor strip, which has a lower strength compared to the mutually adjacent portions. The target separation point may e.g. be formed by means of a transverse to the longitudinal direction of the sensor strip perforation or notch. Accordingly, the temperature sensor element may be e.g. be separated from the monitoring device by the sensor strip is severed at the predetermined separation point. Accordingly, the sensor strip is divided from the predetermined separation point into a connector portion having the connector and a sensor element portion having the temperature sensor element. Upon severing the sensor strip at the predetermined break point, the fastener portion initially remains on the monitor and may be removed later (e.g., mechanically). In order to facilitate or simplify a problem-free severing at the predetermined separation point, the signal lines can e.g. as deposited on the sensor support member (e.g., printed or vapor deposited) thin-layered metal conductive lines.
    Different temperature sensor elements can be provided for different temperature specifications or desired temperature ranges to be maintained; wherein the monitoring device may be configured such that when the temperature sensor element is connected to the monitoring device (i.e., when the connection element of the temperature sensor element is connected to the temperature sensor connection terminal), the target temperature range to be monitored for compliance is detected by identifying the temperature sensor element.
    For example, different sensor strips may be provided for different target temperature ranges; whereby e.g. a first sensor strip type to monitor compliance with a freezer temperature range of -5 ° C to + 5 ° C, a second sensor strip type to monitor compliance with a cool temperature range of 5 ° C to 10 ° C, and a third sensor strip Type can be provided to monitor compliance with an ambient temperature range of 15 ° C to 25 ° C.
    Accordingly, each sensor strip may have a temperature range characteristic that characterizes the predetermined temperature range whose compliance is to be monitored by means of the sensor strip (also referred to as desired temperature range); wherein the monitoring device is designed such that when the sensor strip is connected to the monitoring device, the setpoint temperature range is detected on the basis of the temperature range feature and the settings of the monitoring device are adapted according to the setpoint temperature range predetermined by the sensor strip; so that e.g. the display device is driven in accordance with the respective predetermined desired temperature range and, e.g. the display of the information as to whether a temperature limit violation occurred or not, is adapted to the respective target temperature range to be observed.
    Thus, e.g. be provided that for different target temperature ranges to be monitored a different geometric arrangement and / or number of signal lines, wherein the predetermined by means of the sensor strip target temperature range can be detected by the monitoring device by detecting the occupied slots of the temperature sensor connection terminal. Accordingly, the desired temperature range to be monitored can be characterized by means of the spatial arrangement and / or the number of signal lines of the sensor strip, wherein the monitoring device can be configured such that it detects the spatial arrangement and / or the number of signal lines by means of the latter. Temperature range is detected, its compliance is monitored.
    As another example, it can be provided that different temperature sensor elements are used for different desired temperature ranges (eg temperature sensor elements with different resistance characteristics), wherein the predetermined temperature range predetermined by the sensor strip is detected by the monitoring device by detecting the type of the temperature sensor element can be. Accordingly, the target temperature range to be monitored can be characterized by means of the (type of) the temperature sensor element, wherein the monitoring device can be designed in such a way that it detects the setpoint temperature range by means of which the type of the temperature sensor element is to be monitored.
    Accordingly, one and the same monitoring device can be used without reprogramming for monitoring different desired temperature ranges, wherein the specification of the setpoint temperature range to be maintained is effected simply by selecting the temperature sensor element or sensor strip element. For easier identification by a user, the different target temperature ranges corresponding temperature sensor elements or sensor strips may be marked with different colors and / or labels.
    The transport container may further comprise a strain relief or a strain relief device, which is provided for securing the temperature sensor element or a temperature sensor element having Sensoranbindungsele element (for example, a sensor strip described above) against tensile load. The strain relief is designed such that the temperature sensor element or the sensor connection element can be fastened or fixed inside the transport container by means of the strain relief at one or more positions and can thus be secured against tensile load. It can e.g. be provided to attach the temperature sensor element or the sensor connection element by means of a Velcro fastener or a clamp connection (the sensor strip is fixed, for example, between a wall of the transport container and a clamping device held on the wall) to the transport container. Accordingly, the temperature sensor element can protrude into the interior of the transport container without being separated from the monitoring device by a tensile load possibly resulting therefrom.
    The supply of the monitoring device and the temperature sensor element with electrical energy can be done by means of an integrated into the monitoring device energy storage. The energy storage may e.g. an electric battery or an electric accumulator. Alternatively or additionally, the monitoring device may be equipped with solar cells for power supply; wherein the monitoring device can in particular comprise an accumulator and solar cells, wherein the accumulator can be charged by means of the solar cells.
    Furthermore, the monitoring device can have an additional (eg wireless) communication interface, by means of which the monitoring device or a microprocessor of the monitoring device can be programmed or reset to a defined initial state (ie a reset can be performed) and / or the memory of the data logger is read out can be. The communication interface may e.g. be an infrared interface. By means of such a communication interface, e.g. in case of damage or other functional impairment of the display device, a subsequent readout of the data logged by means of the monitoring device takes place.
    The invention will be illustrated below with reference to embodiments with reference to the accompanying figures, wherein the same or similar features are provided with the same reference numerals; Here are shown schematically:
    1 shows a transport container according to an embodiment;
    2 shows the structure of a monitoring device of the transport container according to FIG. 1 with coupled temperature sensor; FIG. and
    Fig. 3 shows a detail of a transport container according to a further embodiment.
    Fig. 1 shows a reusable transport container 1 (also referred to as Dispobox) according to one embodiment in a lateral sectional view, wherein the transport container 1 has a monitoring device 2. To the monitoring device 2, a temperature sensor element 5 is coupled by means of a sensor strip 3.
    Fig. 2 illustrates the monitoring device 2 with the sensor strip 3 coupled thereto in a plan view. According to FIG. 2, the sensor strip 3 has a temperature sensor 5 and a connecting element 7. The temperature sensor 5 is designed as a resistance thermometer. In addition, the sensor strip 3 has two signal lines 9, which are designed as printed metal conductor tracks and electrically connect the temperature sensor 5 to the connecting element 7. The temperature sensor 5 and the signal lines 9 are arranged on a strip-shaped sensor support member 11 made of an electrically insulating material (e.g., paper or plastic). The length of the sensor strip 3 is 20 cm as an example. The sensor strip 3 has a predetermined separation point 13, designed by means of a perforation, for selectively severing the sensor strip 3, by means of which the sensor strip 3 is inserted into a connecting element section 15, which has the connecting element 7, and a sensor element section 17, which has the temperature sensor 5, is divided.
    The monitoring device 2 has a temperature sensor connection terminal 21 (shown in dashed lines in FIG. 1), a data logger 23 and a display device or display 25, which are accommodated in a common housing 27. The arranged on the sensor strip 3 connecting element 7 and arranged on the monitoring device 2 temperature sensor connection terminal 21 are formed such that they can be releasably connected to form a temperature signal interface 29. In the present case, the connecting element 7 is designed as a plug 7 and the temperature sensor connection terminal 21 as a built-in housing 27 socket 21 so that the monitoring device 2 and the sensor strip 3 can be detachably connected to each other by inserting the plug 7 into the socket 21 (in the figures the monitor 2 and the sensor strip 3 are shown in the coupled state).
    The data logger 23 has a microprocessor and a data storage device (not shown) and is in electrical connection by means of electrical connection lines with the temperature signal interface 29, so that the data logger 23 detected by the temperature sensor 5 temperature readings can be stored and processed , The monitoring device 2 is designed (by means of appropriate programming of the microprocessor of the data logger 23) in such a way that the display 25 is controlled by it on the basis of the detected temperature measured values. The monitoring device 2 is designed to be connected to the temperature sensor connection terminal 21 by connecting the connection element 7 to the temperature sensor connection terminal 21. is activated by inserting the plug 7 in the socket 21 -, so at this time the detection and storage of temperature readings by the
    Datalogger 23 is started. The monitoring device 2 is further designed such that it is deactivated by disconnecting the temperature sensor 5 from the monitoring device 2, so that at this time the detection and storage of the temperature measured values by the data logger 23 is terminated. The separation of the temperature sensor 5 from the monitoring device 2 may e.g. by means of releasing the releasable connection formed between the connecting element 7 and the temperature sensor connection terminal 21 or by severing the sensor strip 3 at the predetermined separation point 13.
    The monitoring device 2 is designed such that it is monitored and displayed whether the temperature detected by the temperature sensor 5 during the detection period was within a predetermined target temperature range or not. The respective target temperature range to be adhered to can depend on the goods to be transported and can thus vary.
    The monitoring device 2 is designed such that the target temperature range to be maintained in each case is predetermined or defined by means of the sensor strip 3; wherein different types of sensor strips are provided for different desired temperature ranges. Each sensor strip 3 has a temperature range characteristic which characterizes the desired temperature range to be maintained in each case. The monitoring device 2 is designed in such a way that when the connecting element 7 is connected to the temperature sensor connection terminal 21 it detects the temperature range characteristic and thus the setpoint temperature range to be maintained.
    By way of example, in the monitoring device 2 according to FIG. 2, the target temperature range to be maintained is defined by the spatial arrangement and the number of signal lines 9 of the sensor strip 3; i.e. Different spatial arrangements and / or numbers of signal lines 9 correspond to different desired temperature ranges. As an example, the temperature sensor connection terminal 21 has four connection lines 31, but in the present case only two of these connection lines 31 are occupied or contacted by the signal lines 9 of the sensor strip 3. The monitoring device 2 is designed in such a way that the target temperature range to be maintained is detected by it by detecting the occupied connection lines 31.
    For better recognition of the different types of sensor strips, the sensor strips can also be provided with a color marking and / or lettering, which identifies the respectively predetermined by them temperature range (eg, "Frozen" or "frozen" for a target temperature range from -5 ° C to + 5 ° C, "cold" or "cold" for a target temperature range of 5 ° C to 10 ° C, and "ambient" or "room temperature" for a target temperature range of 15 ° C to 25 ° C).
    The display 25 is an example of a bistable liquid crystal display or an e-paper display. The display 25 is controlled by the monitoring device 2 (eg by means of the microprocessor of the data logger) such that is displayed by the display 25 in a first display section 33 in human-readable form (eg as plain text and / or in the form of icons), whether the means the sensor strip 3 predetermined target temperature range has been met or not. The display is also controlled by the monitoring device 2 in such a way that in a second display section 35 in machine-readable form (for example as machine-readable code, as QR code according to Fig. 1), the entire temperature history recorded up to the respective time is displayed.
    In particular, the display 25 may be a rectangular e-paper display with a 2.7 inch display diagonal and a resolution of e.g. 264 by 176 pixels or as a rectangular e-paper display with a 2.0 inch display diagonal and a resolution of e.g. Be formed 200 times 96 pixels; wherein each data point of the QR code may be formed of a square of four pixels.
    The monitoring device 2 is further equipped with a power supply device with a solar cell 39. Furthermore, the monitoring device 2 has a wireless communication interface 41 in the form of an infrared interface 41 (for example, according to an IRDA standard), by means of which the monitoring device 2 (or the memory and the microprocessor of the data logger 23) can be read out and reprogrammed.
    The transport container 1 has (see FIG. 1) a lower shell 43 and a closure lid 45. The monitoring device 2 is received in a receptacle 47 which is formed on a boundary wall 45 of the transport container 1; wherein, as an example according to FIGS. 1 and 3, the boundary wall 45 is formed by the closure cover 45 provided for closing the transport container 1 (the lower shell 43 is not shown in FIG. 3). FIG. 1 illustrates the transport container 1 together with a temperature-sensitive transport item 48 received therein.
    In the embodiment according to FIG. 1, the receptacle 47 is designed such that the monitoring device 2 is arranged in the interior of the transport container 1 on the boundary wall or the closure lid 45. According to this embodiment, the closure lid 45 has a transparent portion 49 functioning as a viewing window (which may be formed on the lid 45, for example, by injection). The closure lid 45 has an inner side 51 pointing towards the interior of the transport container 1 and an outer side 53 facing the outside environment of the transport container 1.
    The display 25, the solar cell 39 and the communication interface 41 are arranged on the transparent portion 49 facing the front 54 of the monitoring device 2. According to the embodiment of FIG. 1, the monitoring device 2 is thus arranged on the inside 51 of the boundary wall 45, that the display device 25 with closed transport container 1 from the outside 53 ago (ie from outside the transport container 1 ago) through the transparent portion 49th Through it is visible and thus can be read optically.
