Description

Thermally insulated shipping container Technical Field The invention relates to a thermally insulating transport container as described in the preamble of the characterizing part of claim 1. Background In the medical field, it is often necessary to transport frozen or deep frozen samples or active ingredients over long distances and for long periods of time without interrupting the cooling chain and without allowing the temperature of the associated refrigerated items to exceed the standard. It is known that highly insulated refrigerated transport containers equipped with cold reservoirs are suitable for solving this task, for example transport containers EP 2 041 502 B1 for cooling refrigerated goods. However, particularly when dispensing vaccines that require deep freezing or freezing (e.g., from-70 ℃ to-80 ℃) it is a tricky problem how to transport a large number of small refrigerated containers (i.e., bottles) to the vaccination site (e.g., doctor's office or mobile vaccination station). At these vaccination points, the vaccine is not required simultaneously, but separately and consecutively at intervals, and is thus removed from the transport container. If the transport container is opened and closed for each removal, during each removal, warmer ambient air enters the cooling space within the transport container, resulting in a rapid decrease in the storage capacity of the regenerator and a greatly shortened maximum cool down time (i.e., the time for the article to reach the maximum allowable temperature). Description of the prior art DE 10 2007 008 351 A1 describes a self-cooling transport container which is provided with a rotatable silo like a revolver inside the cooling chamber, in which a plurality of refrigerated product receptacles are arranged in a ring. In the shipping container, a tubular inlet passage member is secured in a centrifugal fashion over the chilled product receptacle ring. By rotating the bin, one refrigerated product receptacle at a time may be placed under the tubular passage member and the refrigerated product may then be removed from the refrigerated product receptacle through the inlet member. Providing such a rotatable bin in a refrigerator which may be at temperatures from-70 ℃ to-80 ℃ requires a great deal of skill to ensure that it rotates reliably even at such low temperatures. Furthermore, the centrifugal arrangement of the tubular passage elements is disadvantageous from an insulation point of view. In addition, such a permanently installed removal device makes it difficult to clean the transport container with which the device is provided, which is particularly disadvantageous if the transport container is intended for transporting medical and pharmaceutical products. Disclosure of Invention The present invention aims to improve a general heat insulating transport container so that the maximum cool keeping time is not seriously reduced even in the case of transporting a large number of refrigerated article insertion holes in which the individual removal of the refrigerated article insertion holes is performed in a manner spaced apart from each other. This object is achieved by a thermally insulating transport container having the features listed in claim 1. The thermally insulated shipping container has an outer shell surrounding an outer insulating chamber, an inner shell disposed within the outer shell and surrounding an inner refrigerant chamber, and a refrigerated chamber disposed within the inner shell, the refrigerated chamber being connected to a tubular inlet passage member of the tubular inner fitment leading to the refrigerated chamber and closable by a closure insert, and having a plurality of refrigerated product chambers for receiving refrigerated products. In this transport container, provision is made according to the invention for the refrigerated compartment to have a central refrigerated compartment surrounded by a plurality of centrifugal refrigerated compartment, the tubular inlet duct elements being arranged centrally in the outer and inner shells and aligned with the central refrigerated compartment, while the centrifugal refrigerated compartment communicates with the central refrigerated compartment or can communicate with the central refrigerated compartment via respective transfer doors. Advantages and advantages In an embodiment according to the invention, the removal of the refrigerated goods container always takes place through the central refrigerated goods compartment located in the axial centre of the refrigerated compartment and thus through the centre of the inner housing surrounded by the refrigerant compartment. If during the extraction warmer ambient air enters the central refrigerated compartment, a symmetrical thermal load on the refrigerant will result in a regenerator (the refrigerant compartment provides the thermal load described above) and therefore the storage capacity of the regenerator is only slightly affected.
