Definitions

  • the present invention provides an insulating material for use in the insulation and/or heating of contents, which are placed therein. More specifically, there is provided an insulating material which contains grain enclosed within an outer covering which can be used in the storage and transportation of food and in particular, take away food.
  • heated food is transported in various types of containers, such as cardboard boxes, tinfoil receptacles with cardboard lids, stainless steel containers or plastic containers, both in the fast-food service industry and food catering industry.
  • containers such as cardboard boxes, tinfoil receptacles with cardboard lids, stainless steel containers or plastic containers, both in the fast-food service industry and food catering industry.
  • These particular containers have a limited ability to insulate the heated food and maintain the food's temperature above 63°C, the temperature at which most bacteria have significantly reduced replication rates.
  • Other insulating devices used in the food industry include cardboard boxes, such as those used to hold take away pizza, or other food types which are not going to be consumed at the premises where they were cooked, and which are to be consumed immediately, and preferably without further re-heating.
  • Such boxes and containers can be inserted into a bag designed to provide further insulation to the pizza or foodstuff, in order to maintain the heat of the food.
  • One prior art bag is made of an outer plastic coat, which surrounds an internal insulating foam.
  • Such insulating products have the disadvantage that they can not maintain temperatures above 63°C for any significant amount of time. Furthermore, this type of insulation is expensive to produce and is not suitable for other types of food for example large scale catering meals.
  • the present invention provides an environmentally friendly and cost effective material for use in the insulation of food. Maintaining the temperature of the food not only makes the food more appealing to the consumer, but also prevents potentially toxic bacteria from replicating in the food and thus avoids food poisoning by bacteria like Salmonella, E. Coli and Campylobacter . According to one aspect of the present invention, there is provided an insulating material comprising a grain material, in an outer covering.
  • the insulating material may be formed into a bag or any other appropriate form to facilitate the insulation of food or a container holding food.
  • the word food as used herein includes drinks.
  • the bag can be of any suitable size, shape or configuration.
  • the bag is adapted to form a sealed envelope around the food or container which holds the pre-cooked hot food.
  • the insulating bag at least substantially prevents heat dissipation from the food such that the food is maintained at a temperature high enough to prevent .bacterial growth and replication.
  • the bag may be reusable or disposable, preferably the former.
  • the bag is also preferably quilted, to maintain even coverage of the grain material.
  • the grain is wheat.
  • the grain is a mixture of wheat and another grain type or types.
  • the outer covering material is paper, cotton, or other cloth, Teflon or ' any material suitable for insulation.
  • the insulating bag is heated prior to insertion of food or a food container therein.
  • the insulating material is heated in a microwave oven.
  • the temperature at which the pre-cooked hot food is held at when inside the insulating material is higher than 63°C for as long as possible.
  • a second aspect of the present invention provides a process for insulating heated food including the steps of:
  • the insulating material is as hereinbefore described.
  • the food is located in a container prior to location within the insulating material.
  • the insulating material can be further provided with a temperature reading device, such that the user can readily obtain a temperature reading for the inside of the insulating material .
  • the present invention is useable not only to keep existing food warm/hot, but also to cook or defrost food.
  • the grain can be heated to a certain temperature, for example by an oven or similar, and then used in its own right to transfer the heat in the grain to food enveloped by the insulating material. This provides controlled heat release, without the associated risks of unattended ovens, or over-cooking.
  • the present invention is also extended to other uses involving slow heat release, such as storage heating, in which pre-heating of the grain is released in a location over a following period.
  • the present invention is further extended to any use of the material where heat retention or heat insulation is required.
  • Figure 1 is a plan view of a first insulating bag suitable for insulating hot food
  • Figure 2 is a cross section along AA of Figure 1;
  • Figure 3 is a cross-section of Fig 1 with a hot box therein;
  • Figure 4 is a perspective view of a second insulating bag.
  • Figure 1 shows a pizza box insulating bag 2, having a main body 4 and flap 6.
  • the outer covering material 8 in this case is Teflon.
  • a fastening means 10, in this case Velcro (RTM) is provided on the upper surface of the main body 4 of the insulating bag.
  • a corresponding piece of Velcro is provided along the top rim of the flap 6.
  • RTM Velcro
  • An opening 14 in the bag 2 is of suitable width to allow a pizza box or other suitable food container to be inserted and removed from the insulating bag 2.
  • the bag 2 has seams 15 to form quilted pockets.
  • Figure 2 is a cross-section of the insulating bag 2.
  • the packed wheat grains 12 are surrounded by an outer layer, in this case Teflon 8.
  • Teflon 8 provides further insulating properties as well as toughness and flexibility.
  • the bag 2 is formed such that it has an inside pocket 16 or compartment into which a food container can be inserted.
  • FIG 3 shows the bag 2 in use, insulating a container holding food 22.
  • the bag 2 is in the closed position, with the flap 6 forming a tight seal 20 around the container 22.
  • the bag 2 Prior to having the food container 22 placed inside it, the bag 2 has been heated. This heating heats the grain 12.
  • the grains 12 retain and slowly re-emit this heat. This initial heating of the grains 12 not only results in improved insulation of the food container 22 due to a reduction in the dissipation of heat, but the grains also provide heat which additionally serves to maintain the temperature of the food.
  • the insulating bag 2 is placed into a microwave oven and heated for at least 30 seconds at full power.
  • Wheat has been found to be the best grain to be used for this purpose, possibly due to the high oil: ater content of the seed.
  • 300g of wheat in a bag can be heated in a microwave oven (at 600W power) for 90 seconds.
  • the hot bag Once filled with 200g of hot food cooked to 90°C, the hot bag will keep the food temperature above 63°C for at least 30 minutes.
  • 1.2kg of wheat in the bag can hold 50Og of hot food at a temperature above 63°C for over 60 minutes.
  • the heat produced during heating is maintained for longer period of time because of the higher water to carbohydrate content in the wheat seed itself.
  • the flap 6 is opened and food containing box 22 containing a hot food is placed inside the pocket 16 of the insulating bag 2.
  • the flap 6 is then closed over the pocket entrance so that the Velcro strips 10 come into contact with one another and form a seal .
  • Figure 4 shows a second bag 30 having a quilted design.
  • the current invention provides a cheap low cost environmentally friendly and reliable insulating bag for use in the food catering industries that can maintain food above the critical 63°C temperature for up to one hour or more.

Abstract

L'invention concerne une matière isolante comprenant une matière à grains (12) dans un élément de recouvrement extérieur. De manière générale, la matière forme un sac scellable pouvant contenir des aliments, généralement des aliments cuits. La matière à grains est de préférence du blé. Le sac peut être chauffé au four micro-ondes. L'invention concerne une matière sans danger pour l'environnement et efficace en termes de coût conçu pour isoler les aliments. Le maintient de la température des aliments non seulement rend les aliments plus appétissants pour les consommateurs, mais aussi il empêche des bactéries potentiellement toxiques de se reproduire dans les aliments, évitant ainsi une intoxication alimentaire provoquée par des bactéries.
