Definitions

  • the present invention relates to the packaging of pre-cooked foods intended to be reheated in a microwave oven.
  • the present invention provides a food product comprising first and second nested containers, the first container being a closed container formed of a non-metallic (e.g. plastics) material capable of withstanding retorting conditions, the said first container being in the form of a dish and containing a food which has been subjected to cooking by retorting in the container; the second container being a closed container formed of a non-metallic (e.g. plastics) material capable of withstanding temperatures generated in a microwave oven, the said second container containing a precooked dehydrated foodstuff.
  • a non-metallic e.g. plastics
  • the first and second containers are in the form of a pair of nested bowls.
  • the innermost of the two nested bowls may rest inside the outermost bowl such that the floor of the inner bowl is spaced above the floor of the outer bowl to define a chamber therebetween in which is located the pre-cooked dehydrated foodstuff.
  • the outer bowl may be provided with recesses or projections which engage complementary surfaces on the inner bowl.
  • the outer bowl may be provided with a rim having recesses therein which engage complementary projections on the rim of the inner container, the inner bowl suitably being supported such that the upper surface of its rim is substantially flush with the upper surface of the rim of the outer bowl.
  • the pre-cooked dehydrated foodstuff typically is selected from instant rice, instant pasta, instant potato, instant pulses and instant fruit and vegetables.
  • instant as used herein means that the foodstuff has been pre-cooked and then dehydrated such that when added to cold water and exposed to microwave heating, it rapidly rehydrates to afford a fully hydrated cooked product.
  • the dehydrated foodstuff is fully rehydrated in less than about 8 minutes, for example less than 6 minutes. Most preferably it is fully rehydrated within about 4.5 minutes.
  • a suitable grade of instant pasta may be obtained from, for example, Soubry of Roeselare, Belgium, and a suitable grade of instant rice may be obtained from, for example, Riviana of Houston, Texas.
  • Herbs and spices may also be included in the foodstuff contained within the outer bowl, for example in dehydrated form where appropriate.
  • the inner container must be capable of withstanding both retorting and microwave heating conditions and must be configured so as to allow efficient heating of the food contained therein in the microwave oven.
  • the inner container should have good barrier properties to both air and water vapour. It may be made from, for example, a single or multilayer food grade plastics material. Where such plastics material is gas-, or moisture-permeable, a barrier membrane is provided which may, for example, be sandwiched between inner and outer layers of the plastics material.
  • the barrier membrane can be formed from plastics such as polyvinylidene chloride or ethylene vinyl alcohol polymer.
  • the inner container will be sealed at its open end, prior to the food therein being retorted, by means of a lid which can be formed, for example, from a metal/plastics laminate material or a plastics material, either of which must have moisture- and gas-barrier properties.
  • a lid which can be formed, for example, from a metal/plastics laminate material or a plastics material, either of which must have moisture- and gas-barrier properties.
  • the lid is sealed to the container by means of the "TOR" closing process described in GB 2067157.
  • the container may be filled such that a small headspace volume is left and may then be introduced into a vacuum chamber along with a lid web, a vacuum being applied both above and below a lid web.
  • a profiled heated sealing head is then urged against the lid web and towards a rim or flange on the container thereby to seal the lid web against the rim or flange.
  • Compressed air is then blown against the surface of the lid and the excess webbing trimmed from the periphery of the rim.
  • the integrity of the resulting seal between the inner container and its lid is important for maintaining the commercial sterility of the food contained within.
  • the gas- and moisture-barrier properties of the inner container and its lid are important for maintaining the quality of the food contained within.
  • the inner container can contain a wide variety of wet retorted foodstuffs and since the provision of such retorted foodstuffs is known, details of their precise nature and identity will not be provided here. However, it has been found that the quality of the texture of substantially carbohydrate-based foods such as rice and pasta is impaired by subjecting such foods to cooking by the retorting process, and then storing prior to reheating in a microwave oven. It is thus preferred that the inner container does not contain such substantially carbohydrate-based foods.
  • the viscosity of the wet retorted foodstuff in is the range 100 - 10,000 centipoise (preferably greater than 1750 centipoise, e.g. up to 5000 centipoise) at 20°C as measured by a Brookfield viscometer (RVT) fitted with a spindle number 4 at a speed of 20 r.p.m.
  • RVT Brookfield viscometer
  • the food contained within the first or inner container has a water content equivalent to less than one hundred percent of the water absorption capacity of the dehydrated food in the second or outer container.
  • the outermost bowl can be constructed from the same material as the inner bowl but need not be, since it is not required to withstand such rigorous temperature conditions as the inner bowl. Typically it is formed from a food grade plastics material such as polyethylene, polypropylene or polystyrene.
  • the polypropylene can be a "filled" polypropylene, ie. it can contain certain fillers such as talc, mica and pigments.
  • the outer bowl does not need to be sealed by a closure which has gas-and moisture-barrier properties and hence the manner in which the open end of the bowl is closed is not especially critical.
  • the bowl is closed by means of a peelable plastics lid.
  • the amount of dehydrated food in the outer bowl and the size of the outer bowl are chosen such that the dehydrated food therein, when fully hydrated, will fill at least half of the volume of the container.
  • the ratio of the internal volume of the outer bowl to the internal volume of the inner bowl is in the range 2:1 to 4:1, for example 2:1 to 2.5:1.
  • volume ratio typically is approximately 2.2:1 whereas if the food is a less compact substance such as pasta, the volume ratio is usually somewhat larger, for example approximately 2.4:1.
  • Typical internal volumes for the inner bowl are in the range 100cm3 to 500cm3 for example 200cm3 to 300cm3, eg. approximately 250cm3, whereas typical volumes for the outer bowl are in the range 400cm3 to 2000cm3, for example 500cm3 to 700cm3, eg. approximately 550cm3 to 600cm3.
  • the thickness of the walls of the containers will be generally of the order of 0.3mm to 1.2mm, and may be reinforced at certain points by means of wall portions having a greater thickness.
  • the outer bowl may have a wall thickness of approximately 0.5mm and the inner bowl may have a wall thickness of approximately 0.75mm.
  • the walls and floor of the inner container serve to divide the interior of the outer container into two chambers, a first chamber which is bounded by the outer surface of the inner container and the inner surface of the outer container and a second chamber which is bounded by the inner surface of the inner container.
  • the ratio of the volume of the first chamber to the second chamber suitably is in the range from 2:1 to 1:2, for example 1:1.5 to 1.5:1, preferably 1.5:1 to 1:1.
  • the nested containers may be provided with conduit means to permit liquid to be poured into the chamber defined by the respective floors of the inner and outer bowls without first removing the inner bowl.
  • conduit means to permit liquid to be poured into the chamber defined by the respective floors of the inner and outer bowls without first removing the inner bowl.
  • the conduit means may comprise an opening defined by a portion of the rim of the outer bowl and/or a portion of the rim of the inner bowl.
  • the rim and the adjacent portion of the side wall of the inner bowl may be recessed inwardly such that, together with the rim and adjacent side wall of the outer bowl, there is formed a channel leading to the interior of the lower food chamber.
  • Figure 1 is a plan view of one embodiment showing the inner container resting inside the outer container
  • Figure 2 is a sectional side view showing the inner container resting inside the outer container
  • Figure 3 is a plan view of a container system according to a second embodiment of the invention.
  • the outer container is a thin-walled bowl 1 formed from filled polypropylene by a thermo-forming moulding process in conventional fashion.
  • the bowl is circular in plan and is provided with a rim 2.
  • the rim 2 has two widened portions 3 and 4 which are diametrically opposed and function as handles.
  • the inner edge of the widened portion of the rim has recesses 5 and 6 for engaging complementary widened rim portions 10 and 11 on the inner bowl 9.
  • the undersides of the widened portions 3 and 4 are provided for strengthing purposes with arcuate ribs which appear from above as arcuate grooves 7 and 8.
  • the inner container is also provided with a peripheral rim 12, two widened portions 10 and 11 of which function both as handles and as a means of supporting the inner bowl in the outer bowl.
  • the widened portions 10 and 11 are configured such that they rest in, and are a close fit with, the recesses 5 and 6 in the rim of the outer container.
  • the shallower inner bowl is thus supported in the outer bowl such that its floor is spaced above the floor of the outer bowl to define a chamber therebetween in which a pre-cooked dehydrated substance such as rice or pasta is located.
  • the inner bowl has a laminar structure consisting of inner 12 and outer 13 layers of polypropylene sandwiched between which is a barrier layer 14 formed of ethylene vinyl alcohol polymer.
  • the inner bowl contains a retorted food (not shown) and is sealed at its upper end by means of a peelable barrier membrane 15 (not shown).
  • the outer bowl is provided with a peelable plastics lid 16 (not shown).
  • the food to be retorted is placed into the inner bowl 9 which is then hermetically sealed with the foil membrane 15.
  • the seal is created in known fashion by a combination of heat and pressure applied by a profiled sealing head.
  • the seal is made sufficiently strong to withstand the manufacturing conditions to which it is subsequently exposed, and to ensure that its integrity is maintained throughout any subsequent storage period, but is made such that it is "peelable", ie. it is made sufficiently weak that the consumer can peel the lid away from the container.
  • the container is subjected to retorting ie. the application of heat in the form of steam or hot water, under pressure, in known fashion. The retorting process serves both to cook and to sterilise the food.
  • a foodstuff such as rice, pasta, potato etc. is cooked and is then dehydrated in accordance with known procedures.
  • An appropriate amount of the resulting cooked dehydrated food is then placed into the outer bowl 1 and the sealed inner bowl 9 containing the cooked sterilised food is placed into the outer bowl 1 so that the widened rim portions 10 and 11 of the inner bowl engage and are supported in the recesses 5 and 6 of the outer bowl.
  • a peelable plastics lid 16 is then fitted to the outer bowl to complete the process.
  • both bowls are then subjected to heating in a microwave oven.
  • both bowls may advantageously be removed from the microwave oven before the contents of the outer bowl have fully hydrated (eg.
  • the consumer is presented with a meal which has an authentic layered appearance, ie. the carbohydrate and meat /vegetable sauce components of the meal are in discrete layers.
  • Figure 3 illustrates a set of nested containers generally similar to the containers illustrated in Figures 1 and 2 except that certain modifications have been made to the inner container.
  • the outer container is a thin-walled bowl 17 formed from filled polypropylene.
  • the bowl 17 is generally circular or elliptical in plan and is provided with a rim 18 which has two diametrically opposed widened portions 19 and 20.
  • the inner edge of the widened portions of the rim have recesses 21 and 22 for engaging complementary widened rim portions 23 and 24 on the inner bowl 25.
  • recess 21 and complementary rim portion 23 are shown as being narrower than recess 22 and rim portion 24 respectively, although this need not necessarily be the case.
  • the inner container 25 is provided with a peripheral rim 26, two widened portions 23 and 24 of which function both as handles and as a means of supporting the inner bowl 25 in the outer bowl 17.
  • the shallower inner bowl 25 is thus supported in outer bowl 17 such that its floor is spaced above the floor of the outer bowl 17 to define a chamber therebetween for the purposes described above.
  • the bowls are sealed with protective foil membranes and/or plastic lids (not shown) in a manner similar to that described above in respect of Figures 1 and 2.
  • the inner bowl 25 has a similar laminar structure to, and is constructed of the same materials as, the inner bowl 9 illustrated in Figures 1 and 2. However, it differs from inner bowl 9 with regard to its shape, in that its side wall and rim have a recessed portion 27 which gives the inner bowl a kidney shape in plan. Thanks to the recessed portion 27, there is provided a gap bounded by inner bowl rim portion 28 and outer bowl rim portion 18a which constitutes an opening 29 into the chamber between the floors of the two bowls. The provision of the opening 29 is particularly advantageous as will now be described.
  • the consumer using the food product illustrated in Figures 1 and 2 must separate outer and inner bowls in order to add water to the dehydrated matter in the outer bowl.
  • the opening 29 in the product illustrated in Figure 3 the requisite amount of water can be added to the contents of the outer bowl without separating the two bowls.
  • the food product can subsequently be subjected to microwave heating without the two bowls being separated.
  • a benefit which follows from this is that a "steaming chamber" is created between inner and outer bowls which has the effect of rehydrating the dehydrated foodstuff much more quickly.
  • a further benefit is that the contents of the inner bowl are heated both by the microwave radiation and by heat transfer from boiling water in the outer bowl beneath it. This means that the contents of the inner bowl are heated more uniformly, and a problem often encountered in microwave cooking, ie the formation of cold spots, is thereby avoided.
  • a still further benefit of the nested bowl arrangement of Figure 3 is that the opening 29 provides a means for straining excess water without losing rehydrated foodstuff from the outer bowl.
