Shipping container for perishable food

For the shipment of perishable food items, especially of fish, it is customary to use baskets or wooden boxes and send the fish in them together with bis. Such containers have the disadvantage that the ice melts relatively quickly and the melt water flows out of the container and other general cargo at risk. Containers made from synthetic foam avoid this shortcoming of the containers mentioned. This For mechanical reasons, very thick-walled tanks have good insulation properties and do not let melt water through step out. Their disadvantage is the low mechanical strength, even with thick-walled designs, so that you do not need to be in the trolley can place enough containers on top of each other »The meltwater also collects in these containers on the bottom, so that the lower fish layers lie in the meltwater, which leads to a reduction in the quality of the fish. The containers can continue can only be used as a disposable pack5 but this is its price too high due to the necessary thick-walled training.

There are also shipping boxes for fish known that from a outer insulating container and an insert box "receiving the fish and ice. The insert box can be relatively light and made of cheap material so that it can be used as a disposable packaging. The insulated container consists of a double-walled sheet metal container with an insulating insert ο Its price is relatively high; even when empty it requires the same space as when it is full, i.e. the freight for the empties are relatively high.

The shipping container avoids the mentioned shortcomings of the known containers according to the invention. This container also consists of an outer box and an insert box. According to the invention this container is designed so that the inner box closed by a lid is made of an insulating material, preferably made of a synthetic foam, and the outer box made of a thin-walled plastic of high strength and that the outer box has such a shape that the same boxes can be nested one inside the other.

In the case of a container according to the invention, the inner box which holds the fish and the ice takes over the thermal insulation. Since the mechanical stresses on this box are low, its wall thickness only needs with regard to the thermal insulation to be dimensioned, i.e. it can be made relatively thin-walled. So its price remains low, it is available as a single-use package usable. The outer box consists of resistance

Capable plastic »Such boxes can be used in the practically required Number to be stacked on top of each other. Transport me back the outer boxes can be nested inside each other, so they only take up little space, and you also have Weight low.

In a shipping container according to the invention, the insert box Channels and openings for draining the meltwater from the insert box? the meltwater should be in the outer box accumulate »According to the invention, in the bottom of the insert box, which is designed with a relatively large height, there are several from the underside the box outgoing recesses are attached to accommodate the melt water. These recesses are through holes with Channels in the floor and in communication with the side walls of the box. One achieves so next to the drainage of the water that it with movements and vibrations of the box during transport does not lead to sloshing movements of the water, and thus avoids that the lower fish layers are in the meltwater »

An embodiment of the invention is described below with reference to the drawing, in which show;

Pig. 1 the outer box of a shipping box according to of the invention in perspective, Pig. 2 a cover for this box, Fig. 5 shows the insert box of the container, also in

perspective view, FIG. 4 a cover belonging to the insert box,

Pig. 5 a plan view of the insert box according to! Pig. 3, FIG. 6 shows a plan view of the bottom of the insert box, FIG. 7 shows a section through a shipping container according to FIG

the invention,

8 shows a part of the section according to Mg «7 with one another stacked lids,

Pig. 9 and 10 two different types of collapsible insert boxes and

iig. 11 is a perspective view of the nested ones outer boxes with lid.

Like Pig. Fig. 1 shows the outer box 1 of the shipping container from a plastic box with conical side walls, so that the same boxes can be nested in one another. The outer one Box is designed at the same time so that the same boxes can be stacked on top of each other when the boxes are against each other be twisted. For this purpose, a stacking surface 3 is formed on the rear wall 2 of the box, which is deeper than the upper edge of the box 4 lies. The projecting front wall 5, which tapers towards the front, has two opposite support points 6, which are shown in FIG the same height as the support surface 3 are. These support points are in the protruding parts of the front wall 5. These Support points in connection with the support 3 enable the same boxes rotated by 180 to be stacked. The upper edge of the box forms a downwardly open TJ (Pig. 7).

A cover 7 is used to cover the box 1 ″ during transport (Mg »2 and 7) · The lid, which is also made of plastic" is smooth on its surface with the exception of four projections8, which are shaped and spaced from one another in such a way that that they are used to lock the bottom of a second box 1 set up on the lid

and a cover 2 has a protruding, circumferential edge 9 / with the same Distance from one another, circumferential web 10, which together, as FIG. 7 shows, encompass the upper box edge 4 of the outer box 1. Longitudinal and transverse ribs 11 and 12 and diagonally extending ribs 13 serve to further stiffen the cover At the rear narrow side of the cover, two lips 14 are formed on the protruding edge part 9. With these lips, the Cover the upper edge 4 of the rear side of the box 2. On the inclined parts of the cover edges 9 are two resilient lips integrally formed, which grip resiliently around the inclined parts of the box edge. Above these lips holes 16 are attached correspond to the holes 17 in the inclined parts of the box edge 4. A wire can be pulled through both holes which can then be secured with a seal.

The lid can also be designed according to Pig. 8 received. The cover, designated here by 18, has an outer downwardly projecting one Edge 19 with an integrally formed lip 20 and an inwardly directed shoulder 21. This training of the Cover allows, as Fig. 8 shows, a fastening.ues cover on the edge of the box and stacking the lids when shipping empty boxes.

The one in Pig. 3 insert box marked 22 "consists of an artificial foam," for example Styrofoam (registered trademark). The box is relatively thick-walled compared to box 1 and is also conical. The box ″ often forms a circumferential shoulder 23 ″ at the edge by weakening the wall thickness. It serves to support the cover made of synthetic foam, designated in FIG. The floor plan of the box is designed so that it can be inserted into the outer box. Channels 25 are formed on the longitudinal sides of the box. They are designed to allow the melt water, which preferably forms first in the uppermost layer, from this layer to the ground The bottom 26 (Jig. 7) has a great height, but several vault-like recesses 27 open to the underside and above these recesses on its upper side channels 28 with inclined side channels 29 , which at their deepest point through holes 30 with the recesses 27 in connection

in
stand. The melt water that collects in the channels 28 and 29 can flow off through the openings 30 to the recesses 27 and collect therein. The recesses 27 are connected to one another ο The base parts 31 are designed with a lower height. The arrangement of individual recesses 27 separated by partition walls ensures that the melt water in the box 1 cannot slosh back and forth when the boxes are being transported, for example when starting or braking.

The one in Pig. 3 boxes shown are conical, so that they can be stacked, but because they are thick-walled,

so you can, through, the stacking of the empty insert boxes during Transport from the manufacturer to the customer does not gain a lot of space. Stacking for return is less of an option, since the insert boxes are intended as one-way packaging and a Disinfect these boxes proportionally after a single use is costly. TJm, however, can be used to gain transport space when shipping the boxes from the manufacturer to the customer 9, i.e. composed of a base 32 and four side walls 33 to 36, with then the side walls must be held together by straps, not shown, unless the gluing Side walls and this is provided with the floor.

The Pig shows another possibility of subdivision. 10. Here the insert boxes are cut according to a diagonal, so that each box half 37 and 38 in corresponding box halves other boxes can be used. Two halves of the box can then be glued to one another or connected by tightening straps will.
