Description

The invention relates to a Device for the transport and storage of objects, in particular of very flammable and explosive objects.

Containers and packaging for Protection of objects against external influences are well known and trained to use this packaging and containers the objects / products to be recorded are adapted or designed so that these objects to be picked up are safe can be stored and transported without damage occur on these products.

For thermally sensitive products the appropriate containers primarily formed with porous foam and also cooling elements provided to protect these thermally sensitive products.

So it is known that through use of insulating materials and cold packs a low temperature in the respective container created and about can be observed for a certain period of time. These containers themselves are designed so that the products to be transported against mechanical damage largely protected are.

So is a packaging from the US 5,102,004 A is known in which materials to be cooled, such as food, are packed together with cooling cushions in a film bag which is inserted into an inner box, the walls of which can be pushed together to form a closed jacket. The walls of the closed inner box are made of a foam and have coatings on both sides with an aluminum foil and the inner box can be inserted in a suitable outer packaging.

Packaging for the transport of thermally sensitive products also describes the DE 101 55 149 C 1 , which is used in particular for the transport and storage of blood samples and from a closed outer box, the walls of which consist of coherent polyurethane plates provided with a metallic or metallized surface layer. Furthermore, this packaging consists of an inner box, the walls of which also consist of a metallic or metallized surface layer made of polyurethane plates and several inner boxes can be arranged in the outer box, and free spaces within the outer box can be equipped with cooling cushions.

Another packaging for the transport of thermally sensitive products is the DE 102 06 109 C 1 become known, which consists of several containers that are inserted into each other and individual containers made of foam or are lined with foam sheets. Furthermore, individual wall parts are designed with or as cooling elements.

Obtain these presented solutions focus primarily on the transportation and storage of thermal sensitive products such as pharmaceuticals, vaccines, Laboratory materials, blood, cell samples and similar products.

A multiple application, especially under Pay attention to the storage and transport of other than those mentioned Products are not possible with these packaging / containers.

Transport containers in the form of folding containers, consisting of corrugated cardboard or similar rigid cardboard material, have found their way into packaging and transport in a variety of configurations. The focus of these transport and storage containers is that the folding containers can be used multiple times, however, these storage containers are only to be used once for storage and transport of certain products, since they are largely designed so that they always have the shape and are adapted to the type of product / object to be transported. So describes the DE 294 7 262 C 2 a folding container made of corrugated cardboard, which is formed on the inside with a plurality of receiving spaces, in which electronic components sensitive to electrostatic discharge can be used and transported.

To protect electronic components cardboard materials are used in the manufacture of the folding container, which at least on one side with an aqueous emulsion in it dispersed carbon particles are provided so as to be transported Protect electronic components against electrostatic discharge.

This solution may, to some extent Dimensions one Shield the electronic components, however folding containers designed in this way against external influences, in particular against shocking Loads, very sensitive and protection against fire is largely excluded, justified through the use of corrugated cardboard or similar rigid cardboard materials.

The invention has for its object a Device for transporting and storing easily flammable and explosive objects the one mentioned at the beginning To be trained in such a way that safe storage and transport, also taking into account increased fire protection, is given and with which the disadvantages of the prior art be largely excluded.

According to the invention this task with the Features of claim 1 solved.

Special configurations and advantageous solutions result itself from the subclaims.

The device according to the invention is designed as a fire protection, transport and storage container, in the broadest sense it represents an accumulator lend, in which easily flammable and explosive objects can be stored and safely transported. It is essential to the invention that the device designed as a fire protection, transport and storage container is designed in two parts and consists largely of two mutually joined containers. Such as an outer container and an inner container with smaller dimensions, so that when these two containers are joined, an intermediate space is formed between the outer container and the inner container, in which protective insulation is provided. This protective insulation fully encompasses the inner container and consists of a temperature-resistant foam glass cement, which is introduced into the space between the two containers in liquid form during the manufacture of the Accusave and forms an intimate connection with the two containers during curing.

Both the outer container and the inner container are executed in two parts, so the entire container also open and can be locked. The area of the parting line between the upper and lower part of the container is covered with a specially designed seal, whereby in the event of a fire, the inside of the storage and transport container thermally to the outside is sealed and thus any temperature leak from the inside of the container is prevented and at the same time a spread of fire and of the associated smoke excluded or largely contained is.

The foam glass cement used consists of a mineral binder in the form of a cement, further from foaming agents, water, air and additives, which in the cured Condition in the container the fire protection insulation forms, which fully encompasses the inner container, so one Complete fire protection insulation given is.

The invention also includes that the created Device with flame-arresting pressure relief is formed, whereby the objects and in the container the container are protected against excess pressure even in the event of a fire.

The arrangement of these flame arrestors Pressure relief is preferably in the lid, the upper part of the container of the storage and transport container provided, the arrangement in the side walls is also possible. Here is the exact positioning and arrangement of this pressure relief also depends on the manner in which the objects provided in the container are arranged are.

The flame arresting pressure relief exists according to the invention formed from a prefilter, from a foam glass cement Filter insert, a filter pack, preferably made of steel wool existing, and a filter cover, which with the outer shell of the upper part of the container connected is. By using the filter inserts and the filter pack, which has certain porosities or openings own and also the filter cover with through openings trained, it is guaranteed that in the event of a fire, this is in the interior of the inner container formed gas can escape from the inside to the outside, thus an overpressure is broken down.

In a preferred embodiment of the storage and transport container according to the invention, preferably for safe storage and transportation of lithium polymer Cells, is the storage and transport container with a temperature-resistant Charging cable formed, which protrudes into the interior. Consequently is an option given the lithium polymer cells in the storage and transport container also during the storage or transport so that these batteries immediately after removal from the storage and transport container fed their use can be.

A particular advantage of the presented Invention is that the arrangement of protective insulation in the storage and transport container a temperature jump from the inside of the container outward of at least 20 min. prevented, thus also a temperature protection over this period guaranteed is because this time is the temperature curve of a lithium polymer cell fire corresponds and is sufficient in time to with a fully loaded storage and transport container one To prevent surrounding fire.

Another benefit one after the Invention trained storage and transport container is that the protective insulation has a very low density, which is advantageous to the total weight of such a storage and transport container impact, thus also portable containers are manufactured can.

With the following embodiment the invention is intended to be closer explained become.

Furthermore, the storage and transport container 1 with a charging cable 11 equipped so that, as already stated above, the inside of the storage and transport container 1 provided batteries can also be charged during storage and transport.

The flame arresting pressure relief belonging to the invention 5 is in the upper part of the container 3 provided, this pressure relief 5 also in the side walls of the storage and transport container 1 can be arranged.

The outer container of the storage and transport container 1 is made of plastic, the outer surface of which can be formed with a specific structure and color. It is also conceivable to manufacture the outer container from a bi-material, such as from a thin steel sheet, the outer sides of which are provided with a plastic layer in the manner mentioned. The inner shells of the inner container are preferably made of a galvanized sheet steel, and, depending on the items to be stored and transported, the inner shells can also be made of another material, such as a corrosion-resistant steel, but also of a temperature-resistant plastic.

The representation according to 2 shows the storage and transport container 1 in the open position and gives an insight into its interior.

It is shown that the inner container consists of two inner shells 7 ; 9 which exists in the upper and lower part of the container 3 ; 2 used and with interiors 8th ; 10 are formed in the closed state of the storage and transport container 1 develop its storage and transport space.

Between the inner walls of the lower and upper part of the container 3 ; 2 and the outer walls of the inner shells 7 ; 9 is the protective insulation 6 provided, which is provided both in the lateral spaces and to the bottom parts of these components.

The protective insulation 6 consists of a foam glass cement, which is mixed into the designated and described spaces after it has been mixed in liquid form. This foam glass cement is designed so that after it has hardened, it creates an intimate connection between the inner shell 7 to the upper part of the container 3 and the inner shell 9 to the lower part of the container 2 out forms. Furthermore, the temperature-resistant foam glass cement is designed in such a way that it has a porosity which gives the hardened foam glass cement a low weight and, on the other hand, it is also ensured that it remains inside the storage and transport container for a necessary period of time 1 possible fire or explosion that does not endanger the environment.

This is largely achieved by the fact that in the storage and transport container 1 , preferably in the lid or in the upper part of the container 3 , a flame arresting pressure relief 5 is provided.

Training and arrangement of pressure relief 5 is in the 3 shown.

The pressure relief 5 itself consists of a perforated cover plate 12 , a pre-filter 13 , a filter insert made of foam glass cement 16 , a filter pack formed from preferably steel wool 17 and one with through openings 19 trained filter cover 18 ,
