Detailed Description of the Preferred Embodiment

[0039] A novel ice pack and ice pack grid system will be described hereinafter. Although the invention is described in terms of specific illustrative embodiments, it is to be understood that the embodiments described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.

[0040] Coolers along with ice packs are typically used in order to transport or to temporary store objects in an environment with temperature lower than the temperature outside of the cooler. The ice packs are typically dropped down the cooler or positioned on either side of the cooler and then multiple objects to be cooled are thrown into the cooler to form a pile. [0041] Such messy arrangement of the objects to be cooled does not lead to equal distribution of temperature in the cooler and the objects that are located closer to the ice packs are usually colder than the ones that are stored in the middle of the pile.

[0042] The ice packs and the ice pack grid system as described herein may help to improve and to provide more uniform distribution of the cold temperature in the cooler.

[0043] The ice pack grid system as described herein may provide a plurality of spaces that are partially surrounded by walls formed by portions of the ice packs. The size of such spaces may be configured to embrace at least partially each individual object to be stored in the cooler. Such configuration may permit the objects to be in almost similar temperature conditions.

[0044] The objects that may need to be cooled may be various items such as, for example, containers and/or objects (including but not limited to, living objects). For example, the objects may be cans (e.g. containing beverages) and/or fruits, vegetables, eggs, etc. Various drugs and medications may also need to be temporary stored and/or transported in a cooler environment.

[0045] Figure 1 shows an example embodiment of an ice pack 100, in accordance with present invention. The ice pack 100 may have a hollow body 110 which may be adapted to receive a freezable substance 150. For example, the freezable substance 150 may be liquid, such as water and/or hydroxyethyl cellulose, carboxymethyl cellulose (also known as CMC), sodium polyacrylate, or vinyl-coated silica gel or any other similar substance preferably approved for use with food. For example, the freezable substance 150 may be superabsorbent polymer, also known as SAP.

[0046] The ice pack 100 has one or more slits 14. Each slit 14 is adapted to receive a portion of another ice pack. Figure 1 shows an example embodiment of the ice pack 100 with four slits 14. It should be understood that the ice pack 100 may have any number of the slits 14. Referring to Figures 1, 2A, and 2B, the body 110 of the ice pack 100 has a width "d", a length "1" and a height "h", and the slits 14 may have slit width "s" and slit depth "k".

[0047] The ice packs 100 are configured to form an ice pack grid system. The ice pack grid system may be formed of the ice packs 100 of identical dimensions or of various dimensions.

[0048] Figure 3 shows an example embodiment of the system 200 with first ice packs 101 and second ice packs 102 having different dimensions. [0049] Referring to Figures 3-6, the system 200 may be adapted to the dimensions of the cooler 300. The ice packs 100, 101, 102 in one system 200 may have not only different lengths, but also different heights and widths. For example, the ice packs 100, 101, 102 of three or more different lengths may be in one system 200. Alternatively, the first and the second ice packs 101, 102 may be identical.

[0050] Referring to Figure 4, the first ice pack 101 has one or more first-pack slits 141 (hereafter "first slits 141"). The second ice pack 102 has one or more second-pack slits 142 (hereafter "second slits 142").

[0051] Each slit 141 may be configured to receive a portion of a second ice pack 102, and to straddle the width of the second ice pack 102, in order to create a grid 200 forming a plurality of spaces (openings) 18, each configured to receive an item, for example, one container 310, as shown at Figures 5-6.

[0052] For example, the first slits 141 may be configured and dimensioned to receive portions 152 (and in particular, width) of the second ice packs 102, while the second slits 142 may be configured and dimensioned to receive portions 151, and in particular ice pack width dl of the ice packs 101. The ice packs 101, 102 may form a center lap joint (attachment) when the first slit 141 of the first ice pack receives the second slit 142 of the second ice pack 102.

[0053] For example, the first and the second slits 141, 142 may be identical to receive the portions of ice packs 102, 101 of similar width, respectively.

[0054] Alternatively, the first ice packs 101 in system 200 may be narrower or wider than the second ice packs 102. The first and the second slits 141, 142 may therefore have different dimensions adapted to the dimensions of the ice packs 102, 101, respectively. The slit width s of the slits 141 of the first ice pack 101 may therefore be adapted to receive the width d2 of the second ice pack 102 and vice versa. For example, the width s of the slit 141 may be wider (e.g. wider by 0.01mm to 50 mm) than the width d2 of the second ice pack 102 in order to receive and accommodate the portion 152 of the ice pack 102 to form the system 200.

[0055] The at least one first ice pack 101 and the at least one second pack 102 may be configured to interlock with each other. For example, the first ice pack 101 and second pack 102 may interlock in a substantially perpendicular configuration, as shown at Figures 3-6.

[0056] Referring back to Figure 1, the slits 14 may be located along the length of the ice pack 100. It should be understood that the slits 14 may be located on any side of the ice pack 100. For example, some of the slits 14 may start from the side 115 of the ice pack 100 and the other may start from the side 116. This may provide another example embodiment ice pack grid system that may have particular interlocking pattern for the ice packs, where some of second ice packs of the system are saddled onto the first ice packs from the top while the first ice packs are saddled onto the other second ice packs.

[0057] The slits 14 may be oriented at an angle alpha ("a" in Figure 1) to the side of the ice pack 100. The angle alpha may be between 10 and 90° to one side 115 of the ice pack 100. Figure 1 shows an example embodiment when the angle alpha is 90°.

[0058] The dimensions of the ice packs 100, 101, 102 such as length, width and/or height, may also be adapted to the size of a cooler 300 the system 200 is used with, so that, when the system 200 is assembled, the system 200 may fit into the cooler 300, as shown at Figures 3-5. For example, the length / of the ice pack 100 may be 2 mm to 20 mm shorter than the length or the width of the cooler 300 to fit comfortably inside the cooler 300 when the ice pack 100 is frozen and when it is defrosted.

[0059] In at least one embodiment, the dimensions of the ice pack 100 may be adapted to the dimensions of the containers 310 to be used with the grid system 200. For example, the distance m between the slits 14 (see Figure 1) may be designed such that the system 200, when assembled, may embrace in each of the formed spaces 18 at least one item such as a container 310, as shown at Figures 4-6. For example, such spaces 18 may be rectangular. Such spaces 18 may be partially closed.

[0060] The ice pack of claim 1, wherein said attachment means comprises at least one first slit extending between the first face and the second face, the first slit being configured to receive at least one portion of a second ice pack.

[0061] Referring now to Figure 7, shown therein is an example embodiment of the ice pack 700 having the cap 170 configured to close the hollow body. For example, the cap 170 may be unscrewable. For example, the cap 170 may be located on a side of the ice pack 700.

[0062] The ice pack 700 may also have one or more recesses 720 on at least one side of the hollow body 710. For example, the recesses 720 may be located on opposite sides (e.g. front and back sides) of the ice pack 700, as shown at Figures 7 and 8. The recesses 720 may thus form a passage 712 of a passage width w. For example, the passage may have a width being of at least 3 times narrower than the width of the body 710.

[0063] The recesses 720 may help to reduce (or prevent) rounding of the ice pack 700 when freezing so that the ice pack 700 may still get into the slits of the other ice pack. Having the recesses 720 may also reduce the amount of material used to make the ice pack 700 and may reduce the cost of the ice pack 700.

[0064] In at least one embodiment, the ice packs 101, 102, 700 as discussed herein may further have at least one cooler attachment (not shown). Such attachment may help to attach the ice packs 101, 102, 700 to the cooler 300, in order to mount the ice pack grid system 200, for example, to the cooler 300.

[0065] In at least one embodiment, the ice packs in the ice pack grid system as discussed herein may further have at least one clipping system for clipping the ice packs to each other. The clipping system may be, for example, one or more buttons and/or clips located on the ice packs and configured to lock the ice packs to each other.

[0066] In at least one embodiment, the ice pack as described herein is generally shaped as a rectangular cuboid, having a first face and a second face which are parallel to each other. In at least one embodiment, each face comprises attachment means adapted to be removably attached to the face of another ice pack generally shaped as a rectangular cuboid, configured to create a grid forming a plurality of open spaces.

[0067] In at least one embodiment, the attachment means may comprise at least one first slit extending between the first face and the second face, the first slit being configured to receive at least one portion of the second ice pack. For example, the attachment means may be center lap joint.

[0068] In at least one embodiment, the attachment means may be configured as a mortise and tenon. When used herein, the term "mortise and tenon" includes attachment means such as "mortise and tenon", "tongue and groove", and "sliding dovetail" attachments (joints). Examples of mortise and tenon attachment means are shown at Figures 9-14.

[0069] Figures 9, 10 and 11 show another example embodiment of the ice pack grid system 900. The system 900 may have a first ice pack 901, a second ice pack 902, and a third ice pack 903, with channels 905 of the first ice pack 901 and protrusions 906 of the second and third ice pack 902, 903. For example, the ice pack 901 may have at least one channel 905, each adapted to receive a protrusion 906 of another ice pack (902, 903). For example, the first ice pack 901 may have the channels 905 on one side (915 or 916 at Figure 11) or both sides 915, 916.

[0070] For example, the channels 905 and protrusions 906 may be configured such that the protrusion 906 may slidingly fit in the channel 905 to mount the second ice pack 902 (as well as the third ice pack 903 and other ice packs) to the first ice pack 901. For example, the protrusion 906 may form one or more grooves 908 (preferably two) configured to receive matching ridges 909 of the channels 905 so that the ice packs may be mounted to each other.

[0071] The first ice pack 901 may also have at least one protrusion 907. For example, the protrusion 907 may be configured to fit into a matching channel (not shown) located on the cooler. The protrusion 907 may also be configured to fit into a matching channel of another ice pack.

[0072] It should be understood that the system 900 may include other ice packs similar to the ice packs 901, 902, 903.

[0073] Figures 12, 13 and 14 show another example embodiment of the ice pack grid system 950. The first ice pack 951 may have openings 955, each configured to receive protrusions 956 of another ice pack (second ice pack 952 and/or third ice pack 953). The first ice pack 951 may also have at least one side protrusion 957. Such side protrusion 957 may be configured to fit into the opening of another ice pack and/or fit into a matching opening of the cooler. The first ice pack 951 may also have a side slit 959 configured to receive a matching protrusion (not shown) of another ice pack and/or the cooler.

[0074] It should be understood that the ice packs may have any number of protrusions that may fit into the matching openings of the other ice packs. For example, the ice pack 952 may have two (or more) protrusions on the same side 910, such protrusions being configured to fit into two (or more) openings that may be located on the first ice pack 951 (instead of one opening 955 as shown at Figure 12). It should be understood that the form of the openings 955 and protrusions 956 may be any form (round, oval, square, etc.) so long as they match each other.

[0075] It should be understood that the system 950 may include other ice packs similar to the ice packs 951, 952, 953.

[0076] While illustrative and presently preferred embodiment of the invention have been described in detail hereinabove, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
