TRANSPORT- AND STORAGE CONTAINER FOR COOLED GOODS

CONTENANT DE TRANSPORT ET DE STOCKAGE POUR PRODUITS REFRIGERES

English Abstract

ABSTRACT
Transport- and storage container for cooled goods, for example
fresh fish, using ice as cooling medium and comprising a first
container of an impact-resisting and heat insulating material,
and a second self-supporting container shaped so that it can
be received as an insert in the first container. The second
container is of a water-proof material and has in its bottom
distance members for keeping the cooled goods separated from
the water from the melted ice. The distance members consist of
a number of vertical cells forming a lattice work upon which
the cooled goods is intended to rest and which cells
comunicate with each other through overflows.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY
OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A transport- and storage unit for cooled goods,
especially fresh fish, using ice as cooling medium, which is
packed together with the cooled goods and when melted is allowed
to flow down about said goods, and which comprises an outer
container of an impact resisting and heat insulating material, a
self-supporting inner container of a water-proof material shaped
so that it can be received as an insert in the outer container
covering the bottom and inner side walls thereof, the insert
being liftable out of the outer container and usable separately,
a lattice work arranged in the bottom of the water-proof inner
container for spacing the cooled goods from the molten ice, said
lattice work comprising a plurality of closed, upwards open cells
communicating with each other through overflows, and a cover
provided with a downwardly projecting edge to engage into a
recess in the upper edge of the outer container, the inner
container at the top being provided with an outwardly projecting,
circumferential flange arranged to rest on the upper edge of the
outer container and sealiningly connect onto the same by means of
the cover.
2. A unit according to claim 1, in which the heat
insulating material is a foam plastic.

Description

7~3
The present invention relates to a transport- and storage
container for cooled goods, especially fresh fish, using ice as
cooling medium, which is pack~d together with the cooled goods
and when melted is admitted to flow down about said goods.
Fresh fish must be transported over long distances, for example
by air, while retaining a constant low temperature of
approximately +2C. Th~ fish is usually packed in boxes of
insulating material, which are placed inside a cover of kraft
0 liner board. As a cooling medium ice is used, which gradually
melts, whereby the water from the melted ice runs around the fish
and cools the same.
Great demands are put on such packings concerning density,
especially if the fish has to be transported with other types of
goods in connection with air transportatlons, where absolutely no
~eakage is permitted.
An ob~ect of the present invention is to provide a transport-and
storage container of the above mentioned type which meets high
demands on insulation as well as on density. Thus the container
should not emit any water and after it has been sealed it should
not emit any water and after it has been sealed it should be so
tight that no smell from for "example" the fish should be felt.
It should have low weight and good insulation qualities so that
the desired temperature level can be kept at least a couple of
days.
According to the present invention there is provided a transport-
and storage unit for cooled goods, especially fresh fish, using
ice as cooling medium, which is packed together with the cooled
goods and when melted is allowed to flow down about said goods,
and which comprises an outer container of an impact resisting and
heat insulating material, a self-supporting inner container of a
water-proof material shaped so that it can be received as an
insert in the outer container covering the bottom and inner side

~z~
walls thereof, the insert being liftable out of the outer
container and usable separately, a lattice work arranged in the
bottom of the water-proof inner container for spacing the cooled
goods from the molten ice, said lattlce work comprising a
plurality of closed, upwards op~n cells communicating with each
other through overflows, and a cover provided with a downwardly
pro;ecting edge to engage into a recess in the upper edge of the
outer container, the inner container at the top being provided
with an outwardly projecting, circumferential flange arranged to
rest on the upper edge of the outer container and sealingly
connect onto the same by means of the cover.
The invention will now be described in more detail by way of
example only with reference to the accompanying drawings in
which:
Fig. 1 shows a vertical section through the container;
Fig. 2 shows a part of the container from above,
The package consists of two parts matching into each other, one
outer box 1 of a heat insulating material such as hard foamed
plastlc, for example Frlgollt, and an lnner box 2 of a water-
proof material for example in~ectlon-moulded polyethylene. The
inner box 2 is shaped so that it can be recelved as an insert in
the outer box 1. The bottom of the lnner box 2 is shaped so that
the water from the lce whlch cools the flsh ls gathered in a
number of vertlcal cells 3 forming a lattice work in the bottom
of the box 2. The cells 3 communicate with each other through
overflows 4. The lattice works forms a lattlce in which the fish
rests and is kept separate from the melted ice
. . .

~2~3Z~
The inner box 2 has at the top an outwards projecting
edge 5, which rests against the upper edge 6 of the outer box 1.
the outer box 1 is provided with a cover 7, which with a rim 8
engages a recess 9 in the upper edge 6 of the outer box 1 and
provides a tight connection of the inner box 2 against the outer
box 1.
The inner box 2 is slightly tapering towards its bottom
and can easily be released from the outer box 1 and be used
separately, both at sales exposure, handling of frozen goods and
of the fish on board on fishing boats. It is pileable so it
requires little space when empty.
The field of appllcation for the packing is of course
not limited to fish handling, but can with advantage be used for
other cooled goods, such as cooling boxes for leisure boats etc.
