Definitions

  • This invention relates in general to boxes and in particular to portable boxes defining a space for containing a product.
  • Foodstuffs to be consumed in passenger aircraft are carried onto the aircraft in boxes contained in metal canisters which are stacked in the aircraft and which have front openings from which the boxes can be removed.
  • the box In the case of frozen foods such as ice creams, frozen yoghurts, and other frozen desserts, the box is usually made of foamed plastics material such as polystyrene, and packets of solid carbon dioxide (known as dry ice) are placed inside the box with the product.
  • foamed plastics material such as polystyrene
  • packets of solid carbon dioxide known as dry ice
  • Such boxes are expensive. Although they are re-usable, they are quite easily damaged during use. Furthermore, since they are generally useful for other purposes, they are often not re-used for the intended purpose.
  • the packets of solid carbon dioxide come into contact with the product, adversely affecting its texture, and they can also cause injury to the hands of anyone removing the product from the box.
  • ovens e.g. microwave ovens
  • the handling involved introduces the risk of contaminating the foodstuff or not keeping it at the required temperature.
  • US-A-2 038 218 discloses a box with insulated walls.
  • the box includes a hinged lid on the underside of which there is a receiver for holding dry ice.
  • US-A-2 734 349 (issued 14 February 1956) and US-A-2 807 402 (issued 24 September 1957) disclose portable boxes in which a separate tray or insert for containing ice is placed on top of the product in the box before the box is closed.
  • the box has a body made of folded sheet material of poor conductivity, such as fibreboard or corrugated fibreboard.
  • US-A-2 807 402 the box comprises multiple inter-fitting bodies of folded paperboard, such that there are at least five layers of paperboard between the exterior and the interior, on all sides of the box.
  • EP-A-0 153 975 discloses a portable box in accordance with the precharacterising part of claim 1.
  • the box disclosed has a removable lid incorporating a compartment which accommodates a cold accumulator and which is open at one end.
  • the box is made of moulded plastics material.
  • What is desired is a container which is inexpensive to manufacture and in which a food product which is to be served chilled or frozen or which is to be heated and served hot can be supplied by the producer, temporarily stored, and made easily available to the user of the product.
  • the present invention provides a portable box as set forth in claim 1.
  • the box illustrated has an outer body part 1 constructed from a single blank of sheet material and having front and rear end walls 2,3, side walls 4 which are longer than the end walls, and a base 6 which, by virtue of the overlapping of the sheet material as indicated in Figures 2 and 3, is twice as thick as the end and side walls.
  • a lip 7 of the sheet material extends inwards from the rear end of one side wall 4 and overlaps the inner surface of the rear end wall 3, for a purpose explained below.
  • An inner body part or liner 8 constructed from a single blank of sheet material is a sliding fit in the outer part 1 and has a front end wall 9 and side walls 11, which are all of equal height and lower than the corresponding walls 2,4 of the outer part 1, and has a rear end wall 12 substantially equal in height to the outer rear end wall 3 but with a middle recess 12a in its upper edge.
  • the liner 8 has no base.
  • a lip 13 of the sheet material extends inwards from the rear end of one side wall 11 and overlaps the outer surface of the rear end wall 12, for a purpose explained below.
  • An optional peripheral spacer 14 ( Figures 8 and 9) of low height, constructed from a single strip blank of sheet material, is a sliding fit in the liner 8 and rests on the base 4 of the outer body part 1. The purpose of the spacer 14 is explained below.
  • a lid 16 constructed from a single blank of sheet material has an outer wall 17 and an inner wall 18, between which a compartment 19 is defined, as well as side walls 21 which are a sliding fit between the side walls 4 of the outer body part 1.
  • the lid 16 closes the box it rests on the upper edges of the front end wall 2 and side walls 11 of the liner 8.
  • a compartment lining 22 consisting of a single blank of sheet material, fits in the compartment 19 with its side edges in contact with the side walls 21 and its upper surface in contact with the lower surface of the outer wall 17. Flaps 23 stamped out of the inner wall 18 are bent up and inserted into transversely extending recesses 24 in the lining 22 in order to define sub-compartments 19a. The flaps 23 have extensions 25 for a purpose explained below.
  • the lining 22 has an extension 26 (with an integral hinge 27) which fits between the rear end walls 3 and 12 of the outer and inner body parts 1 and 8 and which is laterally guided by the above-mentioned lips 7 and 13, which also space the end walls 3 and 12 apart.
  • the lining 22 extends through the front end of the lid 16 to form a grippable flap 28.
  • the front end is closed by an openable closure flap 29 which is integral with the inner wall 18 and which has a lip 31 which engages frictionally with the lining 22.
  • a similar flap is provided at the opposite end.
  • the inner wall 18 of the lid 16 has large apertures 32 spaced along the side edges and therefore adjacent the side walls 11 of the liner 8 of the box. One or more narrower apertures 33 are also provided. There are also apertures 34 and 36 adjacent the front and rear ends respectively. Accordingly, the gas-permeability of the inner wall 18 is at a maximum near the liner 8 (owing to the apertures 32,34,36).
  • a container 37 for containing individual packets of food, is constructed from a single blank of sheet material and extends across the interior of the box. There are further containers, arranged side by side.
  • the container 37 has side walls 38 which are spaced from the side walls 11 of the liner 8 in order to provide convection paths.
  • the end walls 38 and side walls 39 have apertures 41 also providing convection paths.
  • the upper end of the container 37 is open. The above-mentioned extensions 25 of the flaps 23 restrict movement of the container 37.
  • the producer loads the food packets (which have been cooled to the required temperature for storage) into the containers 37 and loads the containers into the box.
  • the box is then stored under refrigerated conditions, e.g. at -18°C.
  • the lid 16 is loaded with packets of dry ice (solid carbon dioxide) as a cooling agent.
  • dry ice solid carbon dioxide
  • the flaps 23 flush with the inner wall 18 and with the closure flap 29 open three dry ice packets are loaded into the compartment 19 one by one.
  • the flap 23 in front of it is raised, and so on. Finally the flap 29 is closed and then the lid 16 is lowered to close the box.
  • the dry ice which is at a temperature of below -78.5°C, cools the air in the compartment 19.
  • the cold air falls over the food packets and also falls down between the liner 8 and the containers 37.
  • the dry ice sublimes at - 78.5°C, extracting heat from the interior of the box and producing cold CO 2 gas which falls through the apertures in the inner wall 18 of the lid, over the food packets and below the liner 8 and the containers 37.
  • the inner wall 18 prevents direct contact between the dry ice packets and the food packets, on the one hand, and a person opening the lid, on the other hand.
  • the box is transported to the point of sale or use and is stored there. If the dry ice sublimes completely, the empty packets are removed from the compartment 19 and replaced with new dry ice packets.
  • the food packets are removed from the box one by one, by opening the lid 16 and reaching into the box, as they are required by the consumer. The lid falls back to the closed position under its own weight and the weight of the dry ice.
  • the sheet material from which the above-described box is made is corrugated cardboard and is therefore of poor thermal conductivity.
  • the outer and inner body parts 1,8 have two corrugated layers alternating with three flat layers, the outer surfaces having a water-resistant coating.
  • the container 37 has a single corrugated layer between two flat layers, the outer surfaces having a water-resistant coating.
  • the remaining components have a single corrugated layer between two flat layers. These materials provide adequate thermal insulation.
  • the sheet material of poor thermal conductivity used for constructing the components of the box may be plastics material.
  • Figures 15 and 16 show a modified container 37' which has at the bottom corners feet 42 which space the container 37' from the base 6 of the box, from the liner 8, and from an adjacent container, thereby facilitating convective flow around the contents of the container. This renders the peripheral spacer 14 superfluous.
  • further apertures 41' are provided adjacent the bottom of the container 37' in this embodiment.
  • the box By inverting the box, so that the compartment is at the bottom, the box could be converted for use for heating its contents.
  • suitable heating means would be inserted into the compartment and the heat would rise by convection.
  • the heating means may comprise an electric heater or a hot-body or a packet containing chemicals which react exothermically, for example.
  • packets containing other frozen substances or packets containing chemicals which react endothermically could be used, for example.
  • the box could be used selectively for heating and cooling.
  • a cooked or partially cooked or uncooked foodstuff could be transported and stored in a chilled or frozen condition and then heated or cooked in the box by replacing the cooling means by heating means.
  • the partition can include "cut-outs" defined by lines of weakness (e.g. perforated lines as indicated in Figs. 1 and 11), which cut-outs can be selectively removed to form the required apertures.
  • the compartment may contain a movable sheet having holes which selectively overlap the apertures in the partition in order to adjust their effective area. The movable sheet may be connected with the compartment lining forming the integral hinge for the lid.
