Description

INSULATED CONTAINER Field of inventionThe invention relates to an insulated container.

Technical Backgroundlt is known to transport various products, such as food and drinks, in so-called ice chests or ice boxes when it is desired that the product is kept ina coo|ed state. This may e.g. be the situation when a family is on a picnic andwould like to keep their picnic food, such as sandwiches, and drinks coo|ed.lce boxes are also used in a number of different commercial applications fortransportation of products in a coo|ed state. lt may e.g. be used whentransporting fish. lce boxes are typically used where it is difficult to securelymaintain a continuous chain of active refrigeration. lce boxes of today are typically formed of an expanded or foamedpolymeric material. Such ice boxes are e.g. disclosed in US 2,552,641 and inUS 3,028,042. The boxes are rigid and are typically used over and over. lt is also common to use rigid boxes formed of expanded polystyrene infood logistics where reuse of boxes is forbidden for hygiene reasons and thepackaging has to be put into landfill waste after one use.

However, the boxes discussed above are all associated with somecommon drawbacks. For instance, when the boxes are transported from thebox manufacturer to the user sites, where they are about to the filled withproducts and used for transportation of coo|ed products, they require basicallythe same transportation volume as they require when they are used fortransportation of coo|ed products. Moreover, at the user site there must alsobe provided significant storage space to accommodate the still unfilled boxes.

Summary of inventionlt is an object of the invention to address the above mentioned drawbacks with the above discussed ice boxes.This object has been achieved by an insulated container to be used fortransporting hot or cold items, the insulated container comprising: an outer box of a paper based box blank folded into a box having abottom panel, side walls extending upwardly from the bottom panel, and anopen top, an insulating sleeve or box with an open top, the sleeve or box beingpositioned inside the outer box and being formed of a paper based sleeveblank folded into a sleeve or box having side walls, a tray being positioned inside the insulating sleeve, the tray beingformed of a paper based tray blank, which is folded into a tray having a bottom panel and side wallsextending upwardly from the bottom panel, which is provided with a plurality of corner panel portions eachinterconnecting two panels forming adjacent side walls, and which has a moisture barrier on a major surface forming aninside surface of the insulated container, and a lid having a bottom surface and a top surface.

Since those components of the insulated container which when in useoccupy a significant volume are made paper based blanks, the transport tothe user site and the storage of the insulated containers at the user site isspace efficient. The components made from paper based blanks may betransported and stored in their flat-laid state and may be may be folded orerected to form the components of the insulated containerjust before theinsulated container is to be used. Moreover, paper-based materials have aglobally organized collection and recycling system and this is yet a furtheradvantage from an environmental perspective. lt may be noted that theinsulating sleeve may be a sleeve having side walls and being open in bothtop and bottom. Alternatively, it may be an insulating box with an open top,i.e. a box having side walls and a bottom, with the side walls extendingupwardly from the bottom.

Preferred embodiments appear in the dependent claims and in thedescription.

The lid is preferably formed of a paper based lid blank being folded intoa box having a bottom panel forming said bottom surface, a top panel forming said top surface, and a plurality of side walls, the side walls interconnecting the bottom panel to the top panel with a distance provided between thebottom panel and the top panel. This is advantageous since also the lid maybe transported and stored in a flat-laid state and may be folded or erected intoa box just before the insulated container is to be used.

The lid has an outer circumferential extension and the outer box has aninner circumferential extension, wherein shapes and dimensions of the outercircumferential extension ofthe lid and the inner circumferential extension ofthe outer box are preferably chosen such that the lid is at least partlyreceivable into the outer box with the bottom surface of the lid facing thebottom panel of the tray. Thereby will the lid be kept securely in positionrelative to the outer box. Moreover, if the lid is provided with a coolingfunctionality, such as being packed with ice inside a box shaped lid or if the lidis formed as or contains an ice pack, or if the lid is packed with an insulatingmaterial, the fact that the lid is at least partly received into the outer box aidsin keeping the cold, such as cold from the lid, inside the insulated container.

The tray has preferably an upwardly facing abutment portionconfigured to be abutted by the bottom surface of the lid. The lid is therebykept at the intended height relative to the tray. Moreover, by having thebottom surface of the lid abutting the tray it is comparably easy to secure thata relatively tight connection is achieved between the tray and the lid such thata closed compartment effectively retaining the cold is formed.

The abutment portion of the tray is positioned at a first height, as seenfrom the bottom panel of the outer box, the first height preferably being belowa height of an upper edge of the side walls of the outer box. Thereby will thebottom surface of the lid be positioned inside the outer box. Thereby will thelid be kept securely in position relative to the outer box. Moreover, if the lid isprovided with a cooling functionality, such as being packed with ice inside abox shaped lid or if the lid is formed as or contains an ice pack, the fact thatthe bottom surface will be positioned inside the outer box aids in keeping thecold from the lid inside the insulated container.

The sleeve blank preferably comprises four major panelsinterconnected and arranged one after the other along a main direction,wherein the major panels are configured to be folded relative to each other and be positioned inside the outer box such that each major panel extendalong an associated side wall of the outer box and with the main directionextending circumferentially along an inside of the outer box. Such a design isspace efficient and is easy to erect into a sleeve.

The sleeve blank is preferably further provided with at least fouradditional panels, wherein each major panel is associated with at least oneadditional panel being positioned, as seen along the major direction,alongside respective major panel, wherein the additional panels areconfigured to be folded relative to each other and relative to the major panelssuch that the sleeve when inserted inside the outer box is at least doublewalled along each side wall ofthe outer box. Such a design makes it possibleto provide an improved insulation capacity in while still being a space efficientand easy to erect into a sleeve.

The insulating sleeve is preferably made of corrugated paper board.This is easy to manufacture and provides good insulating properties relativeto the thickness of the blank.

The moisture barrier on the tray blank is preferably waterproof andleak-tight. The moisture barrier on the tray blank is preferably polymer based.This is easy to manufacture, it provides good moisture barrier and there is agreat variety of known polymers to choose from depending on other demandsapart from the moisture barrier. There is e.g. a known selection of polymergrades that are regarded as food grade. There is e.g. a known selection ofpolymer grades that are regarded as sufficiently tight for transporting biohazardous waste or bio hazardous tissue sample. The exact choice ofpolymer grade is dependent upon how the insulated container is intended tobe used and the different polymer grades suitable for the various uses isknown to a person skilled in the art.

The outer box has a first outer circumference at an upper edge of theside walls and a second outer circumference at the bottom panel, wherein thefirst outer circumference is preferably greater than the second outercircumference. This is a convenient manner of providing internal space forinternal handles within the outer circumference of the outer box while stillsecuring that the sleeve is kept at the intended position by abutting the side walls of the box close to the bottom panel. Moreover, the internal space thusformed also acts as an insulator in that it holds a volume of air standing stillinside this volume.

The outer box blank is preferably provided with top wall panels beingconnected to the side walls and being configured to be folded relative to theside walls and form an upwardly facing, inwardly extending upper rim surfacearound the open top of the outer box. This upper rim surface is in one usescenario used as supporting surface allowing other boxes to be stacked ontop of this box. The inner edges of the rim are preferably used to position thelid in the intended position along the horizontal plane.

The invention may alternatively in short be said to relate to an insulatedcontainer to be used for transporting hot or cold items, the insulated containercomprising: an outer box of a paper based box blank folded into a box havingan open top; an insulating sleeve being positioned inside the outer box andbeing formed of a paper based sleeve blank folded into a sleeve; a tray beingpositioned inside the insulating sleeve and being formed of a paper basedtray blank, which is folded into a tray, which is provided with a plurality ofcorner panel portions each interconnecting two panels forming adjacent sidewalls, and which has a moisture barrier on a major surface forming an insidesurface of the insulated container.

The tray blank 30a, 30b has a moisture barrier37 on a major surface 30a1; 30b1 forming an inside surface 30i of theinsulated container 1. The moisture barrier 37 on the tray blank 30 iswaterproof and leak-tight. The moisture barrier 37 on the tray blank 30a; 30bis polymer based. This is easy to manufacture, it provides good moisturebarrier and there is a great variety of known polymers to choose fromdepending on other demands apart from the moisture barrier. There is e.g. aknown selection of polymer grades that are regarded as food grade. There ise.g. a known selection of polymer grades that are regarded as sufficientlytight for transporting bio hazardous waste or bio hazardous tissue sample.The exact choice of polymer grade is dependent upon how the insulatedcontainer 1 is intended to be used and the different polymer grades suitablefor the various uses is known to a person skilled in the art.

The lid 40 has a bottom surface 45' and a top surface 46'. The lid 40 isformed of a paper based lid blank 40a; 40b. ln figure 11 such a paper basedlid blank 40a according to a first embodiment is disclosed. ln figure 15 such apaper based lid blank 40b according to a second embodiment is disclosed.The lid blank 40a, 40b is intended to be folded or erected into a box 40 havinga bottom panel 45 forming said bottom surface 45', a top panel 46 formingsaid top surface 46', and a plurality of side walls 41-44, the side wallsinterconnecting the bottom panel 45 to the top panel 46 with a distance h40provided between the bottom panel 45 and the top panel 46.

Since the outer box 10, the sleeve 20, the tray 30 and in the preferredembodiment also the lid 40 are made paper based blanks 10a; 10b, 20a; 20b, 30a; 30b, 40a;40b, the transport to the user site and the storage of theinsulated containers 1 at the user site is space efficient. The components 10,20, 30, 40 made from paper based blanks 10a; 10b; 10b, 20a; 20b, 30a; 30b,40a;40b may be transported and stored in their flat-laid state and may be maybe fo|ded or erected to form the components 10, 20, 30, 40 ofthe insulatedcontainer 1 just before the insulated container 1 is to be used.

The |id 40 has an outer circumferentia| extension C40o and the outerbox 10 has an inner circumferentia| extension C10i, wherein shapes anddimensions of the outer circumferentia| extension C40o of the |id 40 and theinner circumferentia| extension C10i of the outer box 10 are chosen such thatthe |id 40 is (as shown in figure 7) at least partly receivable into the outer box10 with the bottom surface 45' of the |id 40 facing the bottom panel 35 of thetray 30. Thereby will the |id 40 be kept securely in position relative to the outerbox 10. Moreover, if the |id 40 is provided with a cooling functionality, such asbeing packed with ice inside a box shaped |id or if the |id is formed as orcontains an ice pack, the fact that the |id is at least partly received into theouter box 10 aids in keeping the cold from the |id 40 inside the insulatedcontainer 1.

As shown in figure 5 and 6, the tray 30 has an upwardly facingabutment portion 36a-d configured to be abutted by the bottom surface 45' ofthe |id 40. The |id 40 is thereby kept at the intended height relative to the tray30. Moreover, by having the bottom surface 45' of the |id 40 abutting the tray36a-d it is comparably easy to secure that a relatively tight connection isachieved between the tray 30 and the |id 40 such that a closed compartmenteffectively retaining the cold is formed.

The abutment portion 36a-d of the tray 30 is positioned at a first heighth36, as seen from the bottom panel 15 of the outer box 10, the first heighth36 being below a height h10 of an upper edge 10ue of the side walls 11-14of the outer box 10 (as shown in figure 6). Thereby will the bottom surface 45'of the |id 40 be positioned inside the outer box 10. Thereby will the |id 40 bekept securely in position relative to the outer box 10. Moreover, if the |id 40 isprovided with a cooling functionality, such as being packed with ice inside abox shaped |id or if the |id is formed as or contains an ice pack, the fact that 11 the bottom surface 45' will be positioned inside the outer box 10 aids inkeeping the cold from the lid 40 inside the insulated container 1.

The outer box 10 has a first outer circumference 10oc1 at an upperedge 10ue of the side walls 11-14 and a second outer circumference 10oc2 atthe bottom panel 15.

When the outer box 10 is formed of the blank 10a, the second outercircumference 10oc2 is basically equal to the first outer circumference 10oc1.This will provide an outer box 10 with straight vertical side walls 11-14, whichmay be useful when it comes to space-efficiency when placing a plurality ofinsulated containers 1 side by side. lt may also be useful to provide a stronginsulated container 1 suitable for being stacked in a stack where a plurality ofinsulated containers 1 are positioned on top of each other.

When the outer box 10 is formed of the blank 10b, the first outercircumference 10oc1 is greater than the second outer circumference 10oc2.This latter is a convenient manner of providing internal space for internalhandles 18a, 18b within the outer circumference 10oc of the outer box 10while still securing that the sleeve 20 is kept at the intended position byabutting the side walls 11-14 of the box 10 close to the bottom panel 15.Moreover, the internal space thus formed also acts as an insulator in that itholds a volume of air standing still inside this volume.

The outer box blank 10a; 10b; 10b is preferably provided with top wallpanels 16a-d being connected to the side walls 11-14 and being configured tobe folded relative to the side walls 11-14 and form an upwardly facing,inwardly extending upper rim surface 16' around the open top 16 of the outerbox 10. This upper rim surface 16' is in one use scenario used as supportingsurface allowing other boxes to be stacked on top of this box. The inneredges 16ie of the rim 16 is preferably used to position the lid 40 in theintended position along the horizontal plane. When the outer box 10 is formedfrom the outer box blank 10a, the inner edges 16ie of the rim 16 are also usedto position the insulating sleeve or box 20 in the intended position along thehorizontal plane, thereby providing space for the handles by the outer box 10being larger in length along the first and third side walls 11, 13 compared tothe length of the insulating sleeve or box 20 along its first and third side walls 12 21, 23. There will thereby on either side 22, 24 of the insulating sleeve or box20 be a space on between the end walls 22, 24 of the insulating sleeve or box20 and the end walls 12, 14 of the outer box 10. lt may be noted that in a specific insulated container 1, may one ormore of the blanks 10a, 20a, 30a, 40a according to the respective firstembodiment disclosed in figures 8-11 be replaced by the corresponding blank10b, 20b, 30b, 40b according to the respective second embodiment disclosedin figures 12-15. lt should also be noted that the blanks 10a; 10b, 20a; 20b,30a; 30b, 40a; 40b are preferred embodiments but that the blanks may bedesigned in any other way as long they may be folded or erected into a box10, a sleeve 20, a tray 30 or a lid 40 having the relevant properties ofrespective component 10, 20, 30, 40.

As shown in figures 5-7, the insulated container 1 is intended to beused according to the following; the tray 30 is positioned inside the sleeve 20as shown in figure 5. The sleeve 20 and tray is positioned in the outer box 10as shown in figure 6. Alternatively, the sleeve 20 is first placed in the outerbox 10 and thereafter is the tray 30 inserted into the sleeve 20. lt may be noted from figure 5, that the sleeve 20 has a height H20being greater than the height H30, h36 of the tray 30. This height difference isaccommodated and hidden behind the downwardly directed panels 17a-d atthe inner edges 16ei of the rim 16 of the outer box 10. ln the embodimentshown in the drawings, the lid 40 is partly received into the outer box 10 andextends partly a distance above the upper edge 10ue of the box 10 (as shownin figure 7). lt is contemplated that there are numerous modifications of theembodiments described herein, which are still within the scope of theinvention as defined by the appended claims.

The outer box blank 10a, 10b, the sleeve blank 20a, 20b, and/or the lidblank 40a, 40b may for instance also be provided with a moisture barrier,preferably a polymer based moisture barrier, on one of both major surfaces.Also such moisture barriers are preferably waterproof and leak-tight. 13 The tray blank 30a, 30b may be provided with a moisture barrier,preferably a polymer based moisture barrier, also on the other major surface.Also this moisture barrier is preferably Waterproof and leak-tight.
