[0001] The invention relates to a disposable package for cooking or heating foodstuffs,
comprising a heat resistant container divided into at least an upper and a lower compartment
by a steam-permeable partition, at least one upper compartment containing the foodstuffs.
[0002] Such disposable packages for foodstuffs, such as frozen food, in which the food can
be heated or cooked are known from US-A-2.850.391. The package described in said specification
comprises an amount of plain water contained in the lower compartment. After sufficiently
heating the ice it melts and is made to boil, whereafter the generated steam will
heat and cook the food. Usually however a blandly tasting, watery food results, requiring
further processing to render it tasty. It is an object of the invention to provide
a package of the general type as described enabling to prepare tastier foodstuff or
foodstuff-combinations and that in an easy way.
[0003] According to the invention there is provided a disposable package for cooking or
heating foodstuffs, comprising a heat resistant container, made of disposable material,
and divided into at least an upper and a lower compartment by a steam-permeable partition,
at least one upper compartment containing the foodstuffs, of which package according
to the invention the lowermost compartment contains an edible substance comprising
aroma and/or flavouring components.
[0004] Preferably the heat-resistant container is made of aluminum. The steam-permeable
partition may be a perforated partition wall. Preferably the partition is made of
a heat-resistant material, such as PET, any other heat-resistant plastic or perforated
aluminum. If only one partition is used, it is preferably so located within the container
that it is substantially horizontal with respect to the top or bottom of the package
during normal use.
[0005] Foodstuffs suitable for cooking or heating are for example foodstuffs composed of
loose units such as beans, peas, asparagus, brussels sprouts, potatoes as well as
meat pieces such as chicken, veal, beef, fish and pork. Larger pieces of fish, meat
and vegetables can also be cooked or heated. The foodstuffs are preferably frozen,
although foodstuffs which are chilled or stored at ambient temperature can also be
used. Optionally, the foodstuff can be raw or at least partly cooked or baked. Upon
heating the foodstuff may be further cooked to give a fully cooked product suitable
for direct consumption.
[0006] The edible substance, which comprises aroma and/or flavouring components, produces
an aromatised or flavoured steam on heating. This can improve the smell and/or taste
of the foodstuff after cooking or heating. The edible substance can, for example,
be seasoned water, broth and mixtures of fat and water, such as butter and water.
To generate sufficient steam during heating, it is preferred that the edible substance
comprises at least 80% by weight of water.
[0007] Preferably the foodstuff to be cooked or heated and/or the edible substance is frozen
or relatively viscous at storage temperatures to prevent admixture of the edible substance
and the foodstuff when stored in the disposable package according to the invention.
[0008] Optimum cooking or heating is achieved when the weight ratio of the edible substance
to the foodstuff is less than 1: 3 and is preferably about 1: 4.
[0009] To facilitate removal of the foodstuff from the package after cooking or heating
it is preferred that the container is provided with a lid which is easily removed.
Suitable lids are for example, plastic lids or removable foils which are attached
to the container, such as aluminium foil.
[0010] Preferably, the lid of the container is provided with one or more venting holes which,
during use, prevent the generation of excess pressure in the container. These venting
holes can be made by piercing holes in the lid prior to heating the package. The escape
of steam through the venting holes indicates that the cooking or heating process has
commenced.
[0011] Preferably the edible substance is removed after cooking or heating the foodstuff.
The package is therefore, preferably provided with means for opening the lowermost
compartment, such as a removable bottom. Most preferably the steam permeable partition
is removable. In use, this partition is removed after the removal of the cooked or
heated foodstuffs. Thereafter the edible substance can be taken from the lowermost
compartment and, if suitable, used as a sauce to accompany the foodstuff. The removable
partition may be provided with two strips, standing up from the partition, which can
be used as gripping means.
[0012] The package according to the invention can be heated in a variety of ways, such as
in a gas oven, hot-air oven, or microwave oven. Particularly preferred is heating
the package on an open flame, such as on a gas-cooker or on a single-burner gas-cooker
commonly referred to as a camping stove. Due to the fact that the steam generated
has a temperature of about 100°C, the required cooking or heating time is independent
of the heating source from the moment that steam is generated. Due to the high efficiency
of contact between the foodstuffs and the steam, a uniformly heated product may be
obtained. If it is desired to increase the area of contact between the foodstuff to
be cooked or heated and the steam, a partition in the form of zig-zag can be used.
[0013] If more than one foodstuff is to be cooked or heated, further steam-permeable partitions
may be arranged in the container.
[0014] If two foodstuffs are to be cooked or heated separately, two horizontal steam-permeable
partitions are used to form three superimposed compartments within the container.
The lowermost compartment contains the edible substance, and the two upper compartments
contain the respective foodstuffs.
[0015] Alternatively it is possible to use one horizontal steam-permeable partition to separate
the container into upper and lower compartments and a vertical partition, which may
also be steam-permeable. The vertical partition separates the upper compartment into
two juxtaposed compartments.
[0016] The invention is further illustrated in the following figures in which preferred
embodiments of the package according to the invention are shown:
- Figure 1
- is a first embodiment of a package according to the invention.
