Description

Cool Box This invention relates to a cool box comprising a base and lid,
each made of stiff yet foldable sheet material, e.g. corrugated material. The container is particularly, but not exclusively, suitable for containing food products or drinks. The invention also relates to a blank of stiff yet foldable sheet material, e.g. corrugated material, which is erectable into a base of a cool box.
Conventionally a cool box has a base and a lid each made from heat insulated plastics material, such as polystyrene. In use of such a cool box one or more ice packs are placed in the cool box together with food or drink to be stored at a cool temperature for subsequent use.
Because the walls of the cool box are heat insulated the ice IS pack(s) retain the food and drink at a cool temperature for a relatively long time even if the surrounding ambient temperature is relatively high. Such conventional cool boxes work well in practice. However they are relatively expensive to manufacture. Moreover since conventional cool boxes are rigid and cannot be collapsed into a smaller size, they take up a relatively large amount of space. Thus transportation and/or storage costs at point of sale are high.
It is an aim of the present invention to provide a relatively cheap cool box made from stiff yet foldable sheet material.
It is also an aim of the present invention to provide a cool box which can be erected on site from a flat condition.
According to one aspect of the present invention there is provided a blank made of stiff yet foldable sheet material covered on one side with heat and/or light reflective material, the blank being erectable into a base of a cool box having a bottom and side walls each with the heat and/or light reflective material on the outside.
Conveniently the blank comprises a rectangular main panel divided into four rectangular side wall panels by three spaced apart fold lines arranged between and parallel to opposite ends of the main panel, each side wall panel having spaced apart first and second sides perpendicular to said fold lines, tab means foldably joined to one end of the main panel means for connection to the other end of the main panel when the main panel is folded about said fold lines into a tubular form of rectangular section during erection of the base of the cool box from the blank, a separate first flap foldably connected to the first side of each side wall panel and a separate second flap foldably connected to the second side of each side wall and having an intermediate fold line spaced from and parallel to the second side, the said first and second flaps being formed so that on erection of the base of the cool box the four first flaps are folded inwardly to partially form the bottom and the four second flaps are folded inwardly against the associated side wall panels and then about the intermediary fold lines against, so as to overlie, the first flaps partially forming the bottom of the cool box. Such a blank enables the base of the cool box to be erected having double thickness side and bottom walls thereby enhancing the thermally insulating properties of the container base.
The provision of a heat and/or light reflective coating on the outside of a cool box protects heat sensitive food or drink stored in the cool box. The blank can be stored in a flat condition for subsequent erection on site.
The walls of the cool box provide it with thermal properties similar to rigid cool boxes made from polystyrene or other heat insulating plastics material.
Suitably the heat and/or light reflective material comprises a metallic foil or metallic foil laminated paper or other sheet material. r - 3 -
Typically the stiff yet foldable sheet material comprises corrugated material, e.g. corrugated fibreboard or cardboard. Corrugated material, with its cavities, has good thermally insulating properties and these thermally insulating properties are considerably enhanced in an erected container having walls of more than a single thickness.
According to another aspect of the present invention there is provided a cool box comprising a base erected from a base blank and having a bottom wall and side walls and a lid having a top wall, the base blank comprising a layer of stiff yet foldable sheet material and a covering layer of a heat and/or light reflecting material.
Suitably the said covering layer is on one side only of the base blank. Conveniently each of said side walls is of double thickness material with its inner and outer surfaces formed by said covering layer.
Conveniently there is provided a further blank of stiff yet foldable sheet material and covered on one side with heat and/or light reflective material for a top of the container. Suitably the further blank has a rectangular top panel and, foldable downwardly therefrom, side wall panels foldably connected to the sides of the top wall panel.
Embodiments of the invention will now be described, by way of example only, with particular reference to the accompanying drawings, in which: Figure 1 is a plan of a first blank of stiff yet foldable sheet material which can be erected to form a base of a cool box according to the present invention; Figures 2 to 8 are schematic views not drawn to scale showing various stages in the erection of the blank shown in Figure 1 into a base of a cool box; - 4 - Figure 9 is a plan of a second blank of stiff yet foldable sheet material for a top of a cool box according to the present invention; and Figures lo and 11 are schematic views not drawn to scale showing stages in the erection of the blank shown in Figure 9 into a top of a cool box.
Figures l and 9 show blanks, generally designated by the reference numerals l and 2, respectively, each made of stiff yet foldable sheet material covered on its downwardly facing side with heat and/or light reflective material. The heat and/or light reflective material must not be rigid since it must allow folding of the stiff yet foldable sheet material and typically comprises a metallic foil, e.g. a highly reflective metal foil such as aluminium foil or the like. Blank 1 is intended to be erected into a base 3 (see Figures 7 and 8) of a cool box and blank 2 is intended to form a lid or top 4 (see Figure 11) of the cool box.
A particularly suitable material for the stiff yet foldable sheet material of the blanks 1 and 2 which has good thermally insulating properties is corrugated material, e.g. corrugated fibreboard or corrugated cardboard, having a pair of spaced apart flat parallel outer liner sheets and one or more fluted or corrugated sheets between these outer liner sheets. If more than one, e.g. two, fluted/corrugated sheets are provided they are separated by one or more intermediate flat sheets. In Figures 1 and 9 the stiff yet foldable sheet material is made from corrugated fibreboard comprising spaced apart outer liner sheets sandwiching a single corrugated sheet, the flutes or corrugations of the corrugated sheets extending in the directions of double- headed arrow A. In the blanks 1 and 9 fold lines are represented by full lines. The fold lines are typically crease lines but may, for example, be full or partially perforated lines. - 5 -
The blank 1 comprises a rectangular main panel 10 divided into four rectangular side wall panels 11-14 by three spaced apart fold lines 15-17 parallel to opposite ends 18 and 19 of the main panel 10. A tab 20 is foldably joined to the side wall panel 11 at the end 18. The side wall panels 11-14 each have spaced apart parallel sides lla and lib, 12a and 12b, 13a and 13b and 14a and 14b, respectively. First flaps 21-24 are foldably connected to the side wall panels 11-14 about fold lines [la-14a, respectively. Second flaps 31-34 are foldably connected to the side wall panels 11-14 about fold lines llb-14b, respectively. Each of the second flaps 31-34 has a first fold line 31a-34a closely spaced and parallel to the fold line llb-14b and an intermediate or second fold line 31b-34b also parallel to the fold line llb-14b. The fold lines 31b- 34b separate the second flaps 31 to 34 into portions 131 and 231, 132 and 232, 133 and 233 and 134 and 234, respectively.
Figures 2 to 8 show various stages in the erection of an open-topped rectangular base from the blank 1. Figure 2 shows initial stages of the folding of the side wall panels 11-14 about fold lines 15-17 so as to create a rectangular configuration, the tab 20 being joined, e.g. adhered, to the side wall panel 14 adjacent its end 19. The first flaps 21- 22 are also shown folded inwardly approximately 90 so as to partly overlap one another and to partially form a bottom of the base of the cool box. In order to erect the configuration shown in Figure 2, the various parts of the blank shown in Figure 1 are all folded upwardly out of the plane of the drawing about the fold lines 15-18 and [la-14a.
In Figures 3 to 7 the second flaps 31-34 are folded inwardly so that portions 131-134 lie flat against the side wall panels 11-14, respectively, and provide double-wall thickness. The portions 231-234 are folded the other way (i.e. downwardly in Figure 1) so as to lie flat against the first flaps 21-24 of the bottom of the base. As can be seen in Figures 8 and 9 in the fully erected base, the heat and/or light reflective material is on the inside and the outside of the double-thickness walls even though it is only applied to one side of the blank 1. Similarly with the bottom of the base, the internal and external surfaces are provided by the heat and/or light reflective material. In other words the corrugated fibreboard or cardboard is not visible in the erected base of the cool box.
Although not shown, overlapping portions of the first flaps partially forming the bottom of the base may be joined, e.g. adhered, together. Also, the portions 231-234 may be joined, e.g. adhered, to the underlying portions of the bottom-forming first flaps. A rectangular panel (not shown), also conveniently made of stiff yet foldable sheet material covered on one side with heat and/or light reflective material, may be positioned inside the container as a top layer for the bottom of the cool box, the heat and/or light reflective material facing upwardly.
The blank 2 comprises a rectangular top panel 50 having side panels 51 and 52 foldably joined to the top panel along sides 53 and 54, respectively, and end panels 55 and 56 foldably joined to the top panel along ends 57 and 58, respectively. End flaps 59,60 and 61,62 are foldably joined to opposite ends of the end panels 55 and 56, respectively.
Figures 10 and 11 show stages in the erection of a top 70 from the blank 2. Conveniently the flaps 59-62 are joined, e.g adhered, to portions of the side panels 51 and 52. In the erected top the external surface is provided by the heat and/or light reflective material. A rectangular panel (not shown), also conveniently made of stiff yet foldable sheet material covered on one side with heat and/or light reflective material, may be positioned inside the top against the top panel 50 so as to provide a double thickness top wall. In this case heat and/or light reflective material would form both the inner and outer surface of the double thickness top wall.
The top 70 can be removably fitted over the open top of the base to provide a thermally insulated cool box.
The provision of heat and/or light reflective layers on the blanks improves the thermal insulating properties of the cool box.
Although corrugated fibreboard/cardboard is the presently preferred material for the blank material on which the heat and/or light reflective material is applied, it can be made, for example, of double skinned fluted polypropylene copolymer or of other stiff yet foldable sheet material which may or may not be corrugated or fluted and which may comprise plastics materials, e.g. EVA (ethylene vinyl acetate), EPS (polyform) or PVC. - 8 -
