Abstract

A double-walled transport container has at least one pipe (7, 8) which passes through an outer wall (4) of the container to be disposed between the outer wall (4) and an inner wall (3), of the container. The pipe (7, 8) is provided with a number of outlets (9) which extend in a water-tight manner through the said inner wall (3). The end of the said at least one pipe (7, 8) that passes through the outer wall (4) of the container terminates in a socket (11) provided with a connector (12) within a well-shaped recess (10) in the outer wall (4) of the container so that the socket (11) and connector (12) lie within the external limits of the container.

Description

The present Invention relates to an arrangement in a doublewalled container, especially a transport container. The expression double-walled in this connection means double walls and a double bottom.

The kind of containers which are intended in connection with the invention are relatively large containers, e.g. containers having a transport volume of 300 liters. Such containers are much used for transport and freezing of fish in blocks. Being double-walled the containers will obtain high rigidity with low expenditure of material, and will have relatively good thermal insulation.

It is an object of the present invention to propose an improvement of containers of the above mentioned kind, so that the containers may be used for other purposes, and provide advantages in conventional use.

A new application of such containers will be transport of fish for stocking, e.g. fish for the fish breeding industry. To day, fish for stocking, and the like must be transported by special vehicles or special tanks. This is expensive as well as often cumbersome. In connection with the invention it is, among others, an object to be able to use common transport containers for transport of fish for breeding. Such transport containers are inexpensive and may readily be moved across short distances and be transported by the aid of common vehicles across longer distances.

According to the invention this is achieved by an arrangement in double-walled containers which is characterized by the fact that at least one pipe with a number of outlets is provided in the interspace between the inner and outer wall and is extended in a water-tight manner through the Inner container wall, and that the ends of the pipe are extended through the outer container wall in the shape of a socket piece which is provided with a pipe connection.

By the aid of the arrangement according to the Invention 5 thawing of fish frozen in blocks in the container may he sped up by pumping a thawing medium into the container through the pipe. On the other hand, fresh fish, e.g. on hoard of a fishing vessel or during transport may be supplied with a coolant, e.g. supercooled sea water, so that fish may be stored for a longer time in a fresh, non-frozen state.

As regards transport of, e.g. fish for breeding, the transport container is filled with water and during transport oxygen may he supplied to the water in the container through the piping system, and fish for breeding may thus stay for a long time in the container.

The invention is explained in more detail reference to an embodiment of the invention.

Figure 1 shows the container from above. below with Figure 2 Figure 3 is a sectional Figure 1, and shows a section container with a view through through the nozzle . the container of inner wall of the The double-walled container according to the embodiment is a standard transport container with a transport volume of 300 litres. The container has an inner wall 1, an outer wall 2, an inner bottom 3, and an outer bottom 4. In the double bottom 3, 4 through ducts 5 and 6 are provided for Insertion of the fork of a fork truck. Between inner and outer bottom 3, 4 of this embodiment two separate piping systems 7, 8 are provided. Five nozzle niples 9 are connected to pipe 8. Pipe 7 is extended through inner wall 1 and ends with a socket 11 in a well-shaped recess 10. Socket 11 is provided with a connection 12 for joining with an external system for supply of gas or liquid. Pipe system 8 is provided with ten nozzles 9 and, like pipe 7, extendss outwards through inner wall 1 and ends in well 10 in the shape of a socket 11 with a connection 12. Pipe 7 is intended for connection with a source of oxygen which will provide live fish for breeding with necessary oxygen during storage and transport in the container.

Pipe 8 is intended for connection with an external source for supply of a thawing medium, if desired a coolant. By the aid of a thawing medium fish frozen in blocks may be thawed more rapidly, and hy the aid of a coolant, e.g. supercooled sea water, fresh fish will have prolonged keeping quality. The outlets from pipes 7 and 8 have the shape of niples 9 which were passed through the internal bottom 3 and were firmly moulded into the latter during production in order to provide a tight passage.

Mounting of the pipe systems may readily he carried out during casting of the containers. The whole piping system with outlet nozzles is placed inside the mould before filling with the raw material. By the aid of special fastening points pipes and niples are held in place during casting.

In the embodiment according to the drawing two particular pipe systems 7, 8 are shown. The pipe systems may have other designs, and it may also he considered, only to place one pipe system In a container which is designed for a special application.

When the container is used for transport of fish for breeding, the transport may be carried out without harming the fish, since the whole supply system for oxygen sits outside the internal bottom 3. There will thus be no installations inside the container which might harm the fish.

If the container is to be used for a thawing container or a cooling container the whole pipe system will he a firmly integrated part and reversal/emptying may be carried out without any damage to pipes or niples.

Because there is ready access to the pipe ends they may readily be blinded from outside, so that the containers may also be used for other and more conventional purposes.
