DETAILED DESCRIPTION OF THE INVENTION

[0034] Figure 1 is an exploded perspective view of a preferred embodiment of a container holder 100 showing the cover 102, insert 103 and base 101. In this embodiment, the base 101 and cover 102 are substantially the same in this embodiment, having approximately equal height, length and width, however this is not essential as, for example, the heights of the cover and the base may differ. For example, the height of the cover may be less than the height of the base. Side views of the cover 102, insert 103 and base 101 are shown in Figures 3, 5 and 6. Figure 2 depicts another preferred embodiment of a container holder 200 similar to the container holder 100 of Figure 1, but with a refillable insert 201. A side view of the insert 201 of Figure 2 is shown in Figure 4.

Date Recue/Date Received 2021-08-13

[0035] The depicted container holder 100, 200 is configured to hold 6 cylindrical containers 1200 (see Figure 12), which are typically cans, such as cans of soda, other soft drinks, or beer, which have the same diameter (D) and preferably the same height (H).

[0036] The base and cover have approximately equal length and width so that the cover can be placed on top of the base, thereby, as shown in Figure 11, forming an assembled container holder, or a "container holder assembly", with an outer surface that is a substantially rectangular cuboid, as shown in Figure 12, and interior surfaces defining an interior space that is isolated from the surrounding environment.

[0037] The base 101 and cover 102 both have similarly scalloped inner walls, as can be seen for the base 101 in Figure 1. Each of the 6 base scallops 104 and 6 cover scallops has a semi-circular horizontal cross-section corresponding to a circle with a diameter of approximately D. When the cover 102 is placed on the base 101 with the walls aligned to form a substantially rectangular cuboid, the scallops in the base and cover are aligned with each other.

[0038] The insert 103, 201 has scalloped outer walls. Each insert scallop 105, 203 has a semi-circular horizontal cross-section corresponding to a circle with a diameter of approximately D. The length of the insert is approximately equal to the inner length of the base 101 and cover 102, which are approximately equal, the inner length being the distance between the inner surfaces of the two end walls in the centre of the base 101 and cover 102. The positions of the scallops 105, 203 on the insert 103 are configured to correspond to the base scallops 104 and cover scallops so that when the insert 103, 201 is inserted in the base 101 (as shown in Figure 10) and the cover 102 is placed on top of the base 101 (as shown in Figure 11) with the upper portion of the insert 103, 201 inside the cover 102, the scallops together define 6 cylindrical regions of diameter approximately equal to D and height approximately equal to H, so Date Recue/Date Received 2021-08-13 that 6 containers of diameter D and height H can be held inside the container holder assembly.

[0039] The base 101 may have a lower landing 106 extending up from the inner surface of the base, and the cover 102 may have an upper landing extending down from the inner surface of the top portion of the cover. As shown in Figures 1 and 7, the landings preferably have the same horizontal cross-section as does the insert 103, with scallops corresponding to those of the insert. As can be seen in Figures 7 and 9, the scallops of the lower landing together with those of the inner walls of the base together define 6 cylindrical regions 700 with a height equal to the height of the lower landing above the inner surface 900 of the bottom portion of the base 101. This facilitates placing the containers into the container holder and keeping them in place when the insert is not present, for example while one insert is removed and another is inserted, or when initially placing containers into the base 101. Similarly, the scallops of the upper landing together with those of the inner walls of the cover together define 6 cylindrical regions with a height equal to the vertical distance of the lower surface of the upper landing from the inner surface of the top portion of the cover 102. This facilitates further holding the containers in place when the container holder is assembled, as depicted in Figure 11, with .. containers disposed in the interior space of the assembled container holder. The heights of the upper and lower landing are generally equal, but may be different.

[0040] The height of the insert 103, 201 is less than or equal to H, being less than or equal to approximately H less the sum of the heights of the upper and lower landings, if any.

[0041] Preferably the cover 102 has the same horizontal cross-sections as shown for the base 101 in Figures 8 and 9, although the heights of the cover and base may be different.

[0042] H is approximately equal to the vertical distance between the inner surface of the bottom of the base 101 and the inner surface of the top of the cover 102. The inner surface of the bottom of the base 101 and the top of the Date Recue/Date Received 2021-08-13 cover 102 refers to the surface at the top and bottom of each of the cylindrical regions formed when the container holder is assembled, with the cover on top of the base, ignoring any landings that may be present.

[0043] While it is not preferred, some embodiments may not include an insert and rely on landings on the inner surface of the bottom of the base and the top of the cover to secure the containers inside the container holder. In some embodiments, the lower landing may extend up to the level of the top ends of the walls of the base (e.g. as shown in Figure 12) and the upper landing may extend down to the level of the bottom ends of the walls of the cover.

[0044] Preferred embodiments include an insert filled with, or that is fillable with, a fluid (liquid or gel), such as distilled water or tap water. The insert filled with fluid can be placed in a freezer to reduce the temperature of the fluid to 0 degrees Celsius or less. In the case water is used, it turns into ice when cooled to 0 degrees Celsius or less. Other fluids may or may not freeze. When the insert is removed from the freezer and placed in a container holder base with containers placed in the base and the cover is placed on top of the base, the scalloped sides of the insert are proximate to, and most preferably in contact with, portions of the sides of the cylindrical containers so that heat is efficiently exchanged between the insert and the contents of the containers. Assuming the containers and their contents are warmer than the insert, the temperature of the containers and the liquid they contain are thereby reduced, or the temperature of the containers and the liquid they contain is maintained at a temperature lower than the environment surrounding the container holder.

[0045] The insert may be made from any suitable material, such as polypropylene. It may be clear or translucent. The insert may be pre-filled with a fluid before the insert is sold. In such embodiments, a fluid may be used that has a freezing point below 0 degrees Celsius, such as propylene glycol.
Alternatively an additive, such as propylene glycol, may be added to water to reduce the freezing point of the water. It is preferred that the fluid be non-toxic.

Date Recue/Date Received 2021-08-13

[0046] In some embodiments, the insert 201 is refillable and has an opening with a cap 202 that can be removed to pour out the fluid in the insert 201 and refill the insert 201 with fluid. The cap is then replaced.

[0047] The cover and base are preferably formed from a flexible insulating material, for example a thermoplastic foam such as polyurethane foam, which is selected to help vibrationally isolate containers, and their contents, in the interior space of the container holder assembly. This is particularly useful where the container holder is used in vehicles such as snowmobiles, jet skis, off-road vehicles, and motor boats that are subject to substantial vibration and irregular forces. The insulating material dampens the vibrations of the vehicle to reduce the amount of vibration transmitted to the contents of the containers disposed in the container holder, which is particularly useful when the contents of the containers are carbonated beverages such as soda (also known as soda pop or just pop) or beer. The insulating material also reduces heat exchange between .. the containers (and the liquid in the containers) and the surrounding environment.

[0048] The insert may be a commercially available product such as a Freez PakTM 6 pack coolant made by Lifoam Industries, a Kleager Can Beer Ice Pack for Lunch, or a 6 Can Long Lasting Ice Pack made by Healthy Packers.

[0049] The insert may be alternatively made from an insulating material, such as the same material used to make the cover and base, for example, a thermoplastic foam such as polyurethane foam. Such an insert may be preferable for use in cold conditions, such as below 0 degrees Celsius when snowmobiling, so that the container holder securely holds the containers but helps to prevent the contents of the containers from freezing by limiting heat exchange between the environment and the contents of the containers. A
container holder comprising a cover, base and foam insert may be sold to consumers, who can purchase suitable commercial ice packs as inserts for summer use, for example.

[0050] Figure 15 depicts and embodiment of an embodiment of a base 1500, or a corresponding embodiment of a cover, configured to receive a generally cylindrical insert 1300. The base and cover may be configured similarly, although there may be some differences, such as markings, height, protrusions, landing configuration, etc. The cover may be placed on the base to form a container holder assembly with a substantially rectangular cuboid outer surface as depicted in Figure 11. The cover and base may each have a landing 1501 which is proximate to, or abuts, the cylindrical insert when the insert is disposed in the base 1500, as shown in Figure 16, or the cover.
Alternatively, only the base may have a landing 1501.

[0051] While the generally cylindrical insert may be strictly cylindrical, as shown in Figures 13 and 16, it is referred to herein as "generally cylindrical" to indicate that it may vary relative to a strict cylinder. For example, the diameter of the insert may vary along the longitudinal axis of the insert, although it is preferred that the insert be strictly cylindrical (which may be referred to as a rod). The ends of the insert may also be rounded in some embodiments. The height of the landing and diameter of the cylindrical insert are preferably selected so that when the insert is disposed in the base (or cover), abutting the landing, the top of the insert does not extend higher than the side and end walls of the base (or lower than the side and end walls of the cover). The inner surfaces of the end walls are preferably configured to be spaced apart by about the length of the insert, so when the insert is disposed in the base (or cover) the ends of the insert are frictionally engaged with the end walls, helping to keep the insert in a fixed position. In this way, embodiments may be configured to receive one insert in the base and a second insert in the cover, in which case a user could choose to use either one or two inserts.

[0052] As with the other embodiments of inserts discussed above, the generally cylindrical inserts may be filled with, or be fillable with, a fluid (liquid or gel), and generally function as discussed above.

Date Recue/Date Received 2021-08-13

[0053] The base and insert are configured so that when the cylindrical insert is disposed in the base, then a portion of the insert is proximate to, or abuts, each container disposed in the base. Similarly for the cover in embodiments where an insert may also be inserted in the cover.

[0054] It is preferred that the bottom portion of the base, including any landing, the side walls of the base, and the end walls of the base are integrally formed, and also that the top portion of the cover, including any landing, the side walls of the cover, and the end walls of the cover are integrally formed. The cover and base may each be formed by injection molding.

[0055] While the embodiments of the container holders depicted in the drawings are configured to hold 6 cans, other embodiments may be configured to hold, for example, 2, 4, 8, 10, 12 or more containers. It is preferred that the number of containers be even, but this is not essential.

[0056] While the multiple containers that are disposable (i.e. can be placed or disposed) in a container holder are generally assumed to have the same diameter and height, this is not essential. For example one of more of the containers may have a height less that the height of the other containers.
Such shorter containers may not be held in place as securely as those having a height approximately equal to the height of the interior space, but they can still be accommodated.

[0057] References to terms such as "vertical", "horizontal", "up", "down", "upright" as used herein assume that the container holder is assembled, with the cover on top of the base and the bottom surface of the base is parallel to the ground or floor, as depicted in Figure 11.

[0058] As used herein "approximately" means +1- 5% unless otherwise stated.

[0059] The qualifier "substantially" as used in "substantially rectangular cuboid" means that the horizontal and vertical cross-sections of the substantially rectangular cuboid need not be strictly rectangular, but may have rounded Date Recue/Date Received 2021-08-13 corners, as can be seen in the figures. Where the term "rectangular cuboid" is used herein without this qualifier, the term is to be interpreted to mean a "substantially rectangular cuboid". A substantially rectangular cuboid, as used herein, may also have protrusions 107, 108 from the base 101 and cover 102.

[0060] The qualifier "substantially" as used in "substantially flat" in respect of a surface means that the subject surface need not be strictly flat, but may, for example, have indentations, extensions ("feet") or landings spanning an aggregate of less than 70%, and preferably less than 50%, of the area of the surface. Where the term "flat" is used herein without this qualifier, the term is to be interpreted to mean "substantially flat".

[0061] The term "cylindrical container" as used herein means that the container has a strictly cylindrical portion, but may also have narrowed portions at the top and bottom of the container or elsewhere. For example, the cylindrical containers 1200 depicted in Figure 12 have a narrowed portion at the top of the containers, as do standard commercially used soda and beer cans.

[0062] The abbreviation mm as used herein refers to millimetres (or in the US, "millimeters"). The abbreviation cm as used herein refers to centimetres (or in the US, "centimeters").

[0063] Where, in this document, a list of one or more items is prefaced by the expression "such as" or "including", is followed by the abbreviation "etc.", or is prefaced or followed by the expression "for example", or "e.g.", this is done to expressly convey and emphasize that the list is not exhaustive, irrespective of the length of the list. The absence of such an expression, or another similar expression, is in no way intended to imply that a list is exhaustive. Unless otherwise expressly stated or clearly implied, such lists shall be read to include all comparable or equivalent variations of the listed item(s), and alternatives to the item(s), in the list that a skilled person would understand would be suitable for the purpose that the one or more items are listed. Unless expressly stated or otherwise clearly implied herein, the conjunction "or" as used in the specification and claims shall be interpreted as a non-exclusive "or" so that "X or Y" is true Date Recue/Date Received 2021-08-13 when X is true, when Y is true, and when both X and Y are true, and "X or Y"
is false only when both X and Y are false.

[0064] The words "comprises" and "comprising", when used in this specification and the claims, are used to specify the presence of stated features, elements, integers, steps or components, and do not preclude, nor imply the necessity for, the presence or addition of one or more other features, elements, integers, steps, components or groups thereof.

[0065] It should be understood that the above-described embodiments of the present invention, particularly, any "preferred" embodiments, are only examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many variations and modifications may be made to the above-described embodiment(s) of the invention as will be evident to those skilled in the art.
