[0103] With reference to the annexed drawings, there is illustrated in FIGS. 1A and 1B a cooler container assembly generally designated 20 comprising a housing container generally designated 22 and a storage container generally designated 24, fitted within the housing container 22 at a fit/snug configuration.

[0104] With Further reference to FIGS. 2A to 2E and 3, the housing container 22 is a box-like structure (bin), comprising a base 30 from which upwardly extend, two side walls 32, a front wall 34 and a back wall 36. The housing container 22 is made of rigid material such as Polypropylene, and in the illustrated example at least side walls 32, front wall 34 and back wall 36 are made of two layered Polypropylene boards, having improved thermal insulation and rigidity. The housing container 22 can be a solid unitary molded item, or it can be configured for assembly/knockdown. The housing container can be made of other material, such as wood, metal or even be a built-in niche made of any material, including concrete, however with access to an opening of the storage container received therein.

[0105] A lid 38 is pivotally secured to the back wall 35 by a hinge system 29 (FIG. 2A), with a stay-open support piston mechanism 40 (FIG. 1B), and a smart lock generally designated 42 is configured at a top front portion of the housing container 22, with a reinforcing steel bar 46 (FIG. 2B) extending at least at a top portion of the front wall 34, and optionally at a front portion of the lid 38, for improving rigidity and tamper-proofing the locking mechanism 42. The smart lock mechanism can be configured with biometric and/or digital features, whereby the lid 38 can be opened only by authorized individuals, under predetermined categories. Likewise, the smart lock mechanism 42 can be configured for remote communication and activation thereof.

[0106] With further attention FIGS. 4A to 4E particular reference is made to the storage container 24 a base wall member 50 and an upwardly extending right side wall 52, a left side wall 54, a front wall 56, and a back wall 58. The walls are made of light weight, high thermal insulating material, such as boards of EPP.

[0107] The storage container 24 is a knock-down structure, wherein it is easily and readily erected or disassembled. However, it is appreciated that the b is a foolproof configuration, wherein it can be assembled only at a particular configuration, in conformity with compartments therein, as will become apparent hereinafter. For making sure that the storage container 24 is properly assembled/erected, the base 50 is configured with several upward extending projections 64 and depressions 66. Respectively, the right side wall 52, left side wall 54, front wall 56 and the back wall 58 are configured, in register with the projections 64 and depressions 66, with downward facing projections 68 and depressions 70, whereby the walls (right side wall 52, left side wall 54, front wall 56 and the back wall 58) can be assembled to the base only at a predesign arrangement, namely the walls cannot be mistakeably replaced with one another. For that purpose, visible indicia can be provided too (apart for the must-match geometry, which by itself is visible too).

[0108] Articulating the walls (right side wall 52, left side wall 54, front wall 56 and the back wall 58) over the base 50 gives rise to a basin defining a thermally insulated interior space 69.

[0109] The storage container 24 is configured with several partition walls, also made of a thermally insulating material, dividing the space 69 into several compartments/chambers, namely a cooling chamber 76, a freezer compartment 78, a chilled compartment 80 and an ambient compartment 82.

[0110] The cooling chamber 76 is defined between a freezer partition wall 86 (extending between the cooling chamber 76 and the freezer compartment 78) and a chill partition wall 88 (extending between the cooling chamber 76 and the chilled compartment 80), and wherein the chilled compartment 80 is partitioned from the ambient compartment 82 by an ambient partition wall 92. The arrangement is such that the compartments 78, 80 and 82 are disposed at fixed locations with respect to one another, with the cooling chamber 76 disposed between the freezer compartment 78 and the chilled compartment 80. However, if desired, the ambient partition wall 92 can be removed, thereby increasing the space of the chilled compartment.

[0111] The chambers/compartments too are configured for foolproof assembly, so as to make sure that the partition walls are properly assembled, in compliance with thermal and airflow considerations, as will be explained herein after in detail. For that purpose, an arrangement is provided such that the walls of the container 20, and the partition walls within the container, can be assembled at a predefined position only.

[0112] As can be seen, best in FIGS. 4C and 4D, the base member 30 is configured with three longitudinal recesses 102, 104 and 106, extending between a back side and a front side of the base member, wherein each of said recesses 102, 104 and 106 has a unique cross section and spans along a different length. Furthermore, the front wall and the back wall 58 are configured with upright extending slots 110, 112 and 114, in alignment with the recesses 102, 104 and 106, wherein each of the slots 110, 112 and 114 has a unique cross section and length.

[0113] In order to assure that each of the freezer partition wall 86, chill partition wall 88 and ambient partition wall 92 is unequivocally assembled at the right location within the basin of the container 20, at a correct orientation, each of said partition walls 86, 88 and 92 is configured at its bottom edge with a projecting ridge (120, 122 and 123, respectively), wherein each of these ridges corresponds with one of the respective recesses 102, 104 and 106 as far as cross section and length. Furthermore, each of the partition walls 86, 88 and 92 is configured at its respective side edges with a laterally projecting rib 129, 132 and 134 (FIG. 4E), wherein each of these ribs corresponds with one of the slots 110, 112 and 114, respectively, as far as cross section and length.

[0114] The combination of the unique configurations of recesses and ridges, and recesses and ribs, respectively, makes sure that the partition walls 86, 88 and 92 can be assembled at the correct location and at the correct orientation, which true positioning has significant meaning as far as air flow and air circulation within the space 70 (i.e. between the compartments 78, 80 and 82) as will be explained herein below.

[0115] The cooling chamber 76 is a space extending between the freezer partition wall 86 and the chill partition wall 88, said walls being spaced apart at a set distance (by their fixed positioning to the front and back wall and the base, as mentioned hereinabove), with a cooling medium support 121 disposed about mid-height of the cooling chamber 76, with two side walls 124 giving rise tighter to a cooling medium receiving space configured for receiving a commercially available dry ice pack, or any other cooling medium such as ice and the like. It is noted that each of the two side walls 124 is configured at a top portion thereof with an opening 128, to be discussed hereinafter, and further wherein said side walls 124 extend inwards from side edges of the partition walls 86 and 88, giving rise to lateral flow paths 130, also to be discussed hereinafter.

[0116] Furthermore, the freezer partition wall 86 is configured at a top portion thereof, with a plurality of refrigerator apertures in the form of thronging longitudinal slots 132. It is apparent the refrigerator apertures 132 extend above the cooling medium support 121 and between the side walls 124. The refrigerator apertures 132 are of uniform cross section and are child-safe, i.e. being sufficiently small to prevent a child for sticking his fingers therethrough. Similarly, the chill partition wall 88 is configured at a top portion thereof, with a plurality of refrigerator apertures, in the form of thronging longitudinal slots 136, however disposed in two rows, above one another, and extending at different heights. The refrigerator apertures 136 too, extend above the cooling medium support 121 and between the side walls 124, and are of uniform cross section and are child-safe, i.e. being sufficiently small to prevent a child for sticking his fingers therethrough. It is appreciated that the total section area of refrigerator apertures 136 is smaller than the total section area of refrigerator apertures 132.

[0117] The freezer partition wall 86 is configured at a bottom portion thereof (below the cooling medium support 121), with a plurality of air circulation apertures 140, wherein said apertures are frustoconical, having a wider base at a face of the freezer partition wall 86 facing the freezer compartment 78, and a narrower base at a face of the freezer partition wall 86 facing the cooling chamber 76.

[0118] The chill partition wall 88 is configured at a bottom portion thereof (cooling medium support 121), with a plurality of air circulation apertures 144, wherein said apertures are frustoconical, and disposed at an opposite orientation of apertures 140 i.e., having a wider base at a face of the chill partition wall 88 facing the chilled compartment 80, and a narrower base at a face of the chill partition wall 88 facing the cooling chamber 76. Furthermore, the apertures 144 are smaller and fewer than apertures 140, wherein a total section area of the apertures 144 is smaller than section area of the apertures 140, to be discussed herein below.

[0119] It is further noted that the apertures 140 and 144 extend over longitudinal depressions 146 and 148, respectively. The arrangement is such that even at the event that an item (i.e. groceries) bear against the wall surface, the respective apertures remain open for air flow therethrough.

[0120] Turning now to ambient partition wall 92, it is configured at a top portion thereof with two thoroughgoing cylindrical apertures 150 (FIG. 8B), said apertures 150 configured for air flow/circulation between the chilled compartment 80 and the ambient compartment 82, to allow some chilled air to flow into the ambient compartment 82 and keep it from heating.

[0121] As noted, for example in FIGS. 4B, 4D, 6B and 8C, the cooling chamber 76 comprises a top cover 170 for covering the cooling chamber space, wherein the top cover 170 is configured with a child-proof arrangement, so as to prevent or reduce the likelihood of a child displacing the top cover between an open position at which the top cover can be opened to facilitate access into cooling chamber space, and a closed position. The child-proof arrangement is a sliding path 172 configured at an inside face of the front wall and the back wall of the storage container, with an arresting block 174 disposed there above.

[0122] At the closed position, the top cover 170 rests over a top edge of the freezer partition wall 86 and the chill partition wall 88. The arrangement is such that removing of the top cover 170 can be facilitated upon first sliding it towards the chilled compartment 80 (rightwards), so as to disengage from arresting block 174, and only thereafter can the top cover 170 be removed upwards.

[0123] Two removable covers 180 and 182 are provided, also made of high thermal insulating material, such as boards of EPP. The covers are each configured with a downward facing chamfered rim 184 and 186 respectively, wherein cover 180 is configured for bearing over top edges of the back wall 58, left side wall 54 and front wall 56, covering the freezer compartment 78, cooling chamber 76 (with the top cover 170 in place) and the chilled compartment 80, wherein the chamfered rim 184 bears against corresponding chamfered seats at the top portion of the respective walls. The cover 182 is configured for bearing over top edges of the back wall 58, right side wall 52 and front wall 56, covering only the ambient compartment 82, wherein the chamfered rim 186 bears against corresponding chamfered seats at the top portion of the respective walls.

[0124] Turning now to FIGS. 9.1 to 9.14 there is illustrated an assembly sequence of a cooler container assembly 20. First, the 38 of housing container 22 is opened (kept at this position by the stay-open support piston mechanism 40) and a base member/wall 50 of storage container 24 is placed into the housing container 22 and placed over the base 30 (FIG. 9.1). It is appreciated that placing the base member 50 in fact determines positioning of all other elements of the storage container 24, owing to the must-match design as discussed herein above.

[0125] Then, left side wall 54 is placed flush against the left side wall 32 of the housing container 22 and articulated to the base 50 such that projections 68 and depressions 70 at the bottom edge of the left side wall 54 engage the projections 64 and depressions 66, at the foolproof manner (FIG. 9.2). Similarly, are assembled the right side wall 52 (FIG. 9.3), the back wall 58 (FIG. 9.4) and the front wall 56 (FIG. 9.5), giving rise to the thermally insulated interior space 69.

[0126] Then, ambient partition wall 92 is slidably introduced into the space 69, all the way done, with laterally projecting ribs 132 snugly received within vertical slots 114 at the front wall 56 and the back wall 58, until and the downward projecting ridge 123 is well received within corresponding respective recess 106 at the base 50 (FIG. 9.6), thereby giving rise to the ambient compartment 82.

[0127] Similarly, freezer partition wall 86 is placed into the uniquely dedicated slot system within space 69, giving rise to the ambient compartment 78 (FIG. 9.7), and the chill partition wall 88 is placed into its respective uniquely dedicated location, giving rise to the chilled compartment 80 and to the cooling chamber 76 (FIG. 9.8). It is appreciated, as mentioned herein before, that the partition walls 92, 86 and 88 can be positioned only at their respective allocated location and only at the correct position thereof.

[0128] Then, the two side walls 124 of the cooling chamber 76 and the cooling medium support 121 are attached to one another to form a sub-assembly 125 (FIG. 9.9) which sub-assembly 125 is then fixed within the cooling chamber 76 (FIG. 9.10). Top cover 170 of the cooling chamber 76 can then be introduced into the sliding path 172 (FIG. 9.11) and is then slidingly displaced along sliding path 172 into its locked position under arresting block 174 (FIG. 9.12). Finally, the two removable covers 180 and 182 are positioned over the respective chambers (FIG. 9.13), obtaining the assembled cooler container assembly 20, ready for use.

[0129] It is appreciated that the cooler container assembly 20, and in particular storage container 24, is knocked down, i.e. disassembled at a reverse sequence of operations.

[0130] It is seen in the drawings that the walls and removable covers are configured with visible indicia, which in the present example reads ‘Frozen’, ‘Cold’ and ‘Ambient’, said indicia aiding in assembly as well as in use of the cooler container assembly 20.

[0131] Turning now to FIGS. 10A and 10B, an air flow scheme is presented, showing a cooling medium 200 (e.g. a dry ice pack) received within the cooling chamber 76 and placed over the cooling medium support 121 between the two side walls 124, wherein cold air flow emitted from the cooling medium 200 is represented by sold arrows 201, and circulated (warmer) air is represented by dashed arrows 203. It is noted that cooled air emitted from the cooling medium 200 flows from the cooling chamber 76 through apertures 132 into freezer compartment 78 and through apertures 136 into chilled compartment 80, wherein the warmer air circulated from the chambers 78 and 80 into the space below cooling medium support 121, then up along lateral flow paths 130 into the cooling chamber, where the air is chilled again by the cooling medium 200, and so on.

[0132] FIG. 11 is an example of a cooler container assembly 20 according to the disclosure, wherein rather than a smart lock there is configured a simple locking arrangement wherein each of the front wall 34′ and the lid 38′ is configured with a locking eye 212 and 214, respectively, lockable by a pad lock (not shown).

[0133] FIGS. 12A to 12E illustrate another example of storage container according to the present disclosure. In the illustrated example storage container 224 comprises walls (side walls 226, back wall 228 and front wall 230) configured at their bottom edge with a (male) dovetail configuration 233 for articulation with a respectively mating (female) dove tail arrangement 235 configured at the base member 238, wherein it is seen that according to this example too there is a foolproof arrangement, whereby the dovetail coupling arrangements differ in size and (optionally in shape too) such that the walls can be secured to the base only at a predefined position.

[0134] The basin space 240 of the storage container 224 is configured with an ambient partition wall 244 giving rise to an ambient compartment 246, a chill partition wall 250 and a freezer partition wall 254 defining between them a cooling chamber 260, and chilled chamber 162 between the chill partition wall 250 and the ambient partition wall 244, and a freezer compartment 266 between side wall 226 and freezer partition wall 254.

[0135] The ambient partition wall 244 is configured at a top portion thereof with several throughgoing air circulation apertures 270, which unlike the previous example have a tapering cross section, with a wider section at the ambient chamber facing side, thereby encouraging cool air flow from the cooling chamber 260 into the ambient compartment 246.

[0136] Yet a difference resides in the cooling chamber 260 lacking a cooling medium support, such that the entire cooling chamber 260 can accommodate a cooling medium.
