Definitions
- Insulated food containers are generally disclosed herein including an insulated food jar with a campfire or stove-heatable inner container.
- insulated food containers cannot be used to heat food or beverages over a flame or other heat source, such as a campfire or on a stove. Portions of the insulated container would melt or otherwise be damaged by the campfire or stove.
- a food or beverage is heated first in a separate pot or other container and then the food or beverage is poured from the pot into the insulated container for storage or transportation. If the food in the insulated container is to be heated, it is generally necessary to remove the food from the insulated container and place it in a container that is safe for heating.
- Some insulated containers permit heating of the food in a microwave oven, but even these insulated containers cannot themselves be used to heat the food or beverage that is stored therein over open flames from a campfire or a stove.
- the user who is camping may choose to eat the heated food, or drink the heated beverage, directly out of the cookware, but in doing so there is little protection from burning oneself on the hot cookware, other than by careful handling of the cookware and careful manipulation of the often flimsy handle attached to the camp cookware.
- an insulated food jar assembly including an insulated outer container, a heatable inner container that is used to heat food or beverages and which slidably engages with an interior of the insulated outer container, and a lid that sealingly mates with the heatable inner container.

- the lid 16 of the insulated food jar assembly 10 is generally in the shape of an inverted cup.
- the lid 16 has a closed top 64 and one or more closed sidewalls 66 extending downward from the outer edge of the closed top 64 .
- the lid 16 has the shape of a circular, cylindrical upside down cup.
- a continuous backup gasket 68 is attached to and extends downward form the lower free edge of the sidewalls 66 .
- the lid 16 further includes a stopper 70 extending downward from the bottom surface of the closed top 64 in the same direction as the downward extending sidewalls 66 .
- the stopper 70 is centered about the axial center of the lid 16 and has a closed bottom end.
- the stopper 70 further includes one or more threads 72 disposed in an outer circumferential surface that is configured to mate with complimentary threads disposed in the neck 48 of the heatable inner container 14 .
- the stopper may include bayonet fastening structures that mate with complimentary bayonet structures disposed on the neck of the heatable inner container, as opposed to threaded structures, without departing from the scope of the present disclosure.
- the lid 16 further includes the stopper gasket 54 disposed about the lower free end of the stopper 70 .
- the stopper gasket 54 is seated inside a groove disposed in the outer circumferential surface of the stopper 70 at the bottom free end of the stopper 70 .
- the stopper 70 is configured to mate inside of the neck 48 of the heatable inner container 14 , with the stopper gasket 54 being configured to sealingly mate against the rigid sealing surface 50 in transition zone of the heatable inner container 14 , so as to form a liquid tight seal there between in order to prevent any fluids from leaking out of the interior space of the inner heatable container 14 .
- the stopper gasket may be seated in a groove located in the bottom surface of the stopper, with the stopper gasket mating against a complimentary sealing surface located in the heatable inner container, without departing from the scope of the present disclosure.
- the stopper gasket may be located at the base (or top) of the stopper 70 and seated in a groove disposed in the bottom surface of the lid's closed top, so that when the lid and inner container are mated, the mouth of the heatable inner container presses against the stopper gasket to form the liquid tight seal.
- Still further arrangements of the lid's stopper gasket are contemplated which form a liquid tight seal with complementary features in the heatable inner container, without departing from the scope of the present disclosure.
- the lid 16 and stopper 70 are preferably made of a heat resistant plastic that will not melt in high heat.
- the lid 16 and stopper 70 may be made from stainless steel, other metals, or other polymers that can withstand high heat, without departing from the scope of the present disclosure.
- the stopper 70 is a hollow cup that has a block of rigid insulation 72 inserted into its open top end. The open end of the stopper 70 is then permanently and sealingly attached to the bottom surface of the lid's closed top 64 , so that the insulation 72 is permanently encapsulated there between, with the closed bottom end of the stopper 70 protruding downward from lid's bottom surface 64 , as previously disclosed. In this manner, the block of insulation 72 inside the stopper 70 provides thermal insulation, which will help prevent excess heat from the consumable contents located inside the inner container 14 from escaping through the lid 16 , and additional structural rigidity to the stopper 70 .
- the insulated food jar assembly 10 is show in its unassembled state.
- food or liquid beverages are placed inside the heatable inner container 14 through the mouth 46 of the inner container 14 .
- the inner container 14 which in one embodiment is made of stainless steel, is then placed over (or the bottom surface of the inner container is placed on) a heat source such as a camp fire, camping stove or grill grate, kitchen stove, or other similar heat source.
- the food or beverage located inside the inner container 14 is thus heated, primarily by conduction of heat through the bottom 42 and/or sidewalls 44 of the inner container 14 .
- the consumable contents in the heatable inner container 14 are heated to the desired temperature, which could be anywhere from room temperature to boiling, or any other desired temperature.
- the user grasps the handles 62 of the inner container 14 and removes the inner container 14 from the heat source.
- the inner container 14 is then slid, bottom first, into the insulated outer container 12 so that the inner container 14 is nested inside the outer container 12 .
- the insulated outer container 14 and the heatable inner container 12 are sized such that there is a relatively close fit between the two, with little space between the respective sidewalls of the mated inner and outer containers.
- the downward-extending portion 60 of the inner container's collar 56 also slides over the top 22 of the outer container's sidewalls and around the friction ring 40 disposed therein.
- the top 22 of the outer container 12 slides into the space that exists between the exterior surface of the inner container's sidewall 44 and the downward extending portion 60 of the inner container's collar 56 .
- the friction ring 40 disposed at the top of the outer container 12 engages with an interior surface of the downward extending portion 60 of the collar 56 to provide a friction fit there between.
- the friction ring 40 includes one or more flexible fins that extend from a main portion of the friction ring 40 and make contact with the interior surface of the downward extending portion 60 of the inner container's collar 56 .
- the fins deflect as they come in contact with the interior surface of the collar 56 and create a friction fit there between.
- the friction ring 40 may be configured differently but still provide for a friction fit between at least a portion of the inner and outer containers so that they will remain nested until an exterior force is applied to pull them apart.
- the friction that is created between the inner and outer containers by the friction ring 40 engaging with the collar 56 on the inner container 14 is sufficient to prevent the inner and outer containers 14 and 12 from sliding apart without the user having to intentionally pull the inner and outer containers apart.
- the stainless steel inner container 14 can be used to heat up food or other consumable materials on a stove or over campfire, and can then be inserted into the insulated outer container 12 for heat retention and safe carrying of the inner container 14 by the user.
- the outer container 12 that holds the heated inner container 14 full of food or other consumable materials provides an insulated barrier to both retain the heat within the inner container 14 and food, thus keeping its contents hot, while at the same time permitting a user to carry the inner container 14 without worrying about getting burned.
- the user may sealingly close the inner container 14 by attaching the lid 16 to the mouth 46 of the inner container 14 .
- the lid 16 of the preferred embodiment is screwed onto the top open end of the inner container 14 by inserting the stopper 70 of the lid 16 into the mouth 46 of the inner container 14 and turning the lid 16 to mate the threads 72 disposed in or on the exterior side surfaces of the lid's stopper with the threads formed in the neck 48 of the inner container 14 .
- the lid and/or stopper may include bayonet style features that mate with complimentary features located on the inner container, or other such similar mating features that are capable of sealingly closing the inner container with the lid.
- the stopper gasket 54 that is disposed in the end of the stopper 70 is seated against the rigid sealing surface 52 in the transition zone 50 of the inner container 14 to form a liquid tight seal there between. In this manner the food and/or beverages contained within the inner container 14 are prevented from leaking out of the inner container 14 .
- the stopper 70 includes a block of insulation 72 encased within the stopper 70 , the act of sealingly mating the lid 16 to the inner container 14 further provides additional heat retention for the food and/or beverage contained therein.
- the backup gasket 68 that extends downward from the free end of the sidewalls 60 of the lid 16 is pressed against an exterior surface of the collar 58 extending from the inner container 14 and forms a liquid tight seal there between.
- the backup gasket 68 provides an additional seal that will prevent the hot food or beverages from leaking past the lid and potentially burning the user, for example when transporting the insulated food jar assembly 10 .
- the insulated food jar 10 may be used to store and transport chilled foods or beverages which are to be consumed in a chilled state or which are to be heated prior to consumption.
- the present food jar assembly 10 has particular utility when used to store or transport foods or beverages that are chilled during storage and transport and then, prior to consumption, the food or beverage is heated while still in the inner container 14 , such as by heating the inner container on a stove or campfire. It is therefore unnecessary to transfer the food or beverage from an insulated transport container to a different container for heating.
- the insulated food jar assembly 10 includes grip features that are decorative as well as useful when opening the food jar 10 .
- the base 32 of the outer container 12 has grip contours that aid the user in obtaining a slip-free grip on the outer container during removal of the lid 16 from the jar assembly 10 and/or during removal of the inner container 14 from the outer container 12 .
- the lid 16 has a grip contour 76 that likewise provides a decorative feature that also assists the user in a slip-free grip of the lid 16 during removal of the lid 16 from the inner container 14 .

Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/708,417 filed Oct. 1, 2012, which is incorporated herein by reference, and also claims the benefit of U.S. Provisional Patent Application Ser. No. 61/724,652 filed Nov. 9, 2012, which is incorporated herein by reference.
- Insulated food containers are generally disclosed herein including an insulated food jar with a campfire or stove-heatable inner container.
- Traditionally, insulated food containers cannot be used to heat food or beverages over a flame or other heat source, such as a campfire or on a stove. Portions of the insulated container would melt or otherwise be damaged by the campfire or stove. Typically, a food or beverage is heated first in a separate pot or other container and then the food or beverage is poured from the pot into the insulated container for storage or transportation. If the food in the insulated container is to be heated, it is generally necessary to remove the food from the insulated container and place it in a container that is safe for heating. Some insulated containers permit heating of the food in a microwave oven, but even these insulated containers cannot themselves be used to heat the food or beverage that is stored therein over open flames from a campfire or a stove.
- The user who is camping may choose to eat the heated food, or drink the heated beverage, directly out of the cookware, but in doing so there is little protection from burning oneself on the hot cookware, other than by careful handling of the cookware and careful manipulation of the often flimsy handle attached to the camp cookware.
- Accordingly, there is a need for a food or beverage jar that can be used to heat food or beverages contained therein by a variety of heating sources, and thereafter is insulated for heat retention and the safe transportation of the hot food or beverage contained therein, without the worry of burning oneself on the heated container.
- Disclosed herein is an insulated food jar assembly including an insulated outer container, a heatable inner container that is used to heat food or beverages and which slidably engages with an interior of the insulated outer container, and a lid that sealingly mates with the heatable inner container. The insulated outer container helps to retain the heat within the heatable inner container and also permits a user to safely carry the heatable inner container without the risk of being burned by the hot surfaces of the heated inner container.
- In one embodiment, the lid includes a stopper that engages a mouth and neck of the heatable inner container. The stopper includes a stopper gasket that forms a liquid tight seal with an inner surface of the heatable inner container. The stopper is itself insulated so as to help prevent heat from escaping the heatable inner container through the lid. The insulated container can also be used to insulate cold items from a warmer environment.
- In another embodiment, the heatable inner container includes a collar extending away from the heatable inner container as well as one or more handles connected to the collar for carrying the heatable inner container when the insulated outer container is not being used, such as when the inner container is being placed on the heat source or removed from the heat source. Attaching the handles to the collar and spacing them apart from the sidewalls of the heatable inner container, which sidewalls are heated up by the heat source, allows the handles to remain at a cooler temperature than the hot sidewalls and hot bottom of the heatable inner container.
- In another embodiment, the insulated outer container includes a friction ring that engages with an inner surface of the inner container's collar when the inner container is slid inside the outer container, so as to provide a friction fit between the inner and outer containers. In this manner, the inner and outer containers generally cannot slide apart without the user slidably pulling the heatable inner container out from within the interior of the insulated outer container.

Therecessed groove 38 is located near the upper open end of the insulatedcontainer 10 and is a continuous groove that extends around the full exterior circumference of theouter container 12. A friction ring orgasket 40 is seated in therecessed groove 38. In one embodiment, thisfriction ring 40 is a rubber ring having one or more fins projecting radially outward. Thefriction ring 40 is configured to provide a friction fit between the heatableinner container 14 and the outer insulatedcontainer 12 so that, as will be explained in further detail below, when the heatableinner container 14 is nested within the outer insulatedcontainer 12, the fins of thefriction ring 40 rub against a portion of the heatableinner container 14 and prevent the twocontainers friction ring 40 may maintain its location on the outer container by spring force resulting from thering 40 being stretched while seated in the recessedgroove 38 and an interference fit with various surfaces of the groove. However, the disclosure of the above embodiment should not be read to limit the shape or configuration of the friction ring to a rubber ring with fins seated in a recessed groove. Rather, additional configurations of recessed grooves and friction rings can be used to achieve the same purpose without departing from the scope of the present disclosure. Accordingly, alternate friction ring configurations other than those disclosed herein may be used without departing from the scope of the present disclosure. Furthermore, in alternate embodiments the friction ring may be permanently bonded to the outer container within the recessed groove, or bonded to the outer surface of the outer container without the need for a recessed groove, depending on the configuration, size, and shape of the friction ring and the desired amount of friction between the outer and inner containers. The friction ring may be made of rubber, silicone rubber, or any other polymer that will achieve the purpose and functionality of providing a friction fit between the inner and outer containers. - Referring to
FIGS. 1 and 4 , the heatableinner container 14 has a closedbottom end 42 and closed sidewalls 44 that extend upward therefrom to form a cup and define amouth 46 of theheatable container 14. In a preferred embodiment, thesidewalls 44 of theheatable container 14 also define aneck 48 disposed adjacent to themouth 46 of theinner container 14. In one embodiment, theneck 48 includes one or more threads formed therein that are used to mate with one or more complimentary threads located on thelid 16 of the insulatedfood jar assembly 10 for sealing thelid 16 to the heatableinner container 14. In this manner, the heatableinner container 14 generally takes the shape of a jar. However, the disclosure of threaded structures should not be read to limit the structures that are used to sealingly mate thelid 16 to themouth 46 of the heatableinner container 14 of the insulatedfood jar assembly 10. In alternate embodiments, the neck may include bayonet mounting features that mate with complimentary bayonet mounting structures located on the lid of the food jar assembly, or otherwise use additional mating structures and methods, without departing from the scope of the disclosure herein. - Furthermore, in one embodiment, the heatable
inner container 14 includes atransition zone 50 disposed between the main portion of thesidewall 44 and theneck 48. Thistransition zone 50 is the portion of thesidewall 44 that reduces the diameter of thesidewall 44 from the main food or beverage carrying portion of theinner container 14 to theneck portion 48 of the heatableinner container 14. In one embodiment, thetransition zone 50 includes arigid sealing surface 52 against which a matedstopper gasket 54 disposed in thelid 16 forms a liquid tight seal to seal theinner container 14 closed when thelid 16 is attached to the heatableinner container 14. - In a preferred embodiment the heatable
inner container 14 further includes acollar 56 connected to thesidewall 44 and extending outward therefrom. In one embodiment, thecollar 56 is connected to thesidewall 44 adjacent to the threads, or other locking feature, disposed in theneck 48 of the heatableinner container 14. In one embodiment, thecollar 56 extends radially outward at 58, away from thesidewall 44 of the heatableinner container 14, and then turns downwards at a predetermined angle, for example 90-degrees, and extends at 60 in the direction of the bottom 42 of the heatableinner container 14. In one embodiment, one ormore handles 62 are attached to thecollar 56. In the illustrated embodiment, a pair of thehandles 62 is provided, one on each side of thecontainer 14. By providinghandles 62 on thecollar 56, thehandles 62 are separated from thesidewall 44 of the heatableinner container 14 and are thus insulated to some extent from thesidewalls 44 when theinner container 14 is heated. During use, thehandles 62 will thus remain cooler than thesidewalls 44 of the heatedinner container 44. - In a preferred embodiment, the
inner container 14 is made from stainless steel. However, in alternate embodiments, the container may be made from alternate materials, such as aluminum, copper, or other such materials that permit the heatableinner container 14, as well as the consumable contents that will be stored therein, to be heated over an open flame, such as from a campfire or gas stove, or to be placed on the heating elements of an electric stove or hot plate or on some other heating means without departing from the scope of the present disclosure. Theinner container 14 may be formed by draw forming processes and/or other manufacturing methods, including welding of various components, such as thecollar 56 and/or handle 62, to the main inner container body. - It will also be appreciated that alternate configurations of the heatable inner container are contemplated without departing from the scope of the disclosure herein. For example, while the depiction of the heatable
inner container 14 shown inFIGS. 1 , 2, 4, and 5 shows thecollar 56 being located between thetransition zone 50 and theneck 48 of theinner container 14, it should be appreciated that in alternate embodiments, the collar may be located at alternate locations without departing from the scope of the present disclosure. For example, in an alternate embodiment, the collar may be located about the mouth of the container, extending radially outward therefrom. In this manner, with the collar located at the top of the inner container, the entire inner container, including the collar and handle, may be draw formed from a single sheet of stainless steel without the need to attach separate components thereto by other processes or subsequent steps. - Referring to
FIGS. 1 , 2, 4, and 5, thelid 16 of the insulatedfood jar assembly 10 is generally in the shape of an inverted cup. Thelid 16 has a closed top 64 and one or moreclosed sidewalls 66 extending downward from the outer edge of theclosed top 64. In a preferred embodiment, thelid 16 has the shape of a circular, cylindrical upside down cup. Acontinuous backup gasket 68 is attached to and extends downward form the lower free edge of thesidewalls 66. Thelid 16 further includes astopper 70 extending downward from the bottom surface of the closed top 64 in the same direction as the downward extendingsidewalls 66. Thestopper 70 is centered about the axial center of thelid 16 and has a closed bottom end. Thestopper 70 further includes one ormore threads 72 disposed in an outer circumferential surface that is configured to mate with complimentary threads disposed in theneck 48 of the heatableinner container 14. However, as will be appreciated, in alternate embodiments the stopper may include bayonet fastening structures that mate with complimentary bayonet structures disposed on the neck of the heatable inner container, as opposed to threaded structures, without departing from the scope of the present disclosure. - The
lid 16 further includes thestopper gasket 54 disposed about the lower free end of thestopper 70. In one embodiment, thestopper gasket 54 is seated inside a groove disposed in the outer circumferential surface of thestopper 70 at the bottom free end of thestopper 70. Thestopper 70 is configured to mate inside of theneck 48 of the heatableinner container 14, with thestopper gasket 54 being configured to sealingly mate against therigid sealing surface 50 in transition zone of the heatableinner container 14, so as to form a liquid tight seal there between in order to prevent any fluids from leaking out of the interior space of the innerheatable container 14. It should be appreciated that in alternate embodiments the stopper gasket may be seated in a groove located in the bottom surface of the stopper, with the stopper gasket mating against a complimentary sealing surface located in the heatable inner container, without departing from the scope of the present disclosure. In still alternate embodiments, the stopper gasket may be located at the base (or top) of thestopper 70 and seated in a groove disposed in the bottom surface of the lid's closed top, so that when the lid and inner container are mated, the mouth of the heatable inner container presses against the stopper gasket to form the liquid tight seal. Still further arrangements of the lid's stopper gasket are contemplated which form a liquid tight seal with complementary features in the heatable inner container, without departing from the scope of the present disclosure. - The
lid 16 andstopper 70 are preferably made of a heat resistant plastic that will not melt in high heat. Alternatively, thelid 16 andstopper 70 may be made from stainless steel, other metals, or other polymers that can withstand high heat, without departing from the scope of the present disclosure. In one alternate embodiment, thestopper 70 is a hollow cup that has a block ofrigid insulation 72 inserted into its open top end. The open end of thestopper 70 is then permanently and sealingly attached to the bottom surface of the lid's closed top 64, so that theinsulation 72 is permanently encapsulated there between, with the closed bottom end of thestopper 70 protruding downward from lid'sbottom surface 64, as previously disclosed. In this manner, the block ofinsulation 72 inside thestopper 70 provides thermal insulation, which will help prevent excess heat from the consumable contents located inside theinner container 14 from escaping through thelid 16, and additional structural rigidity to thestopper 70. - Referring to
FIG. 1 , the insulatedfood jar assembly 10 is show in its unassembled state. To use the assembly, food or liquid beverages are placed inside the heatableinner container 14 through themouth 46 of theinner container 14. Theinner container 14, which in one embodiment is made of stainless steel, is then placed over (or the bottom surface of the inner container is placed on) a heat source such as a camp fire, camping stove or grill grate, kitchen stove, or other similar heat source. The food or beverage located inside theinner container 14 is thus heated, primarily by conduction of heat through the bottom 42 and/orsidewalls 44 of theinner container 14. The consumable contents in the heatableinner container 14 are heated to the desired temperature, which could be anywhere from room temperature to boiling, or any other desired temperature. When the consumable contents have reached the desired temperature, the user grasps thehandles 62 of theinner container 14 and removes theinner container 14 from the heat source. Referring generally toFIGS. 2-5 , theinner container 14 is then slid, bottom first, into the insulatedouter container 12 so that theinner container 14 is nested inside theouter container 12. The insulatedouter container 14 and the heatableinner container 12 are sized such that there is a relatively close fit between the two, with little space between the respective sidewalls of the mated inner and outer containers. - Referring to
FIG. 4 , when the heatableinner container 14 is slid inside the insulatedouter container 12, the downward-extendingportion 60 of the inner container'scollar 56 also slides over the top 22 of the outer container's sidewalls and around thefriction ring 40 disposed therein. Thus, the top 22 of theouter container 12 slides into the space that exists between the exterior surface of the inner container'ssidewall 44 and the downward extendingportion 60 of the inner container'scollar 56. Thefriction ring 40 disposed at the top of theouter container 12 engages with an interior surface of the downward extendingportion 60 of thecollar 56 to provide a friction fit there between. In one embodiment, thefriction ring 40 includes one or more flexible fins that extend from a main portion of thefriction ring 40 and make contact with the interior surface of the downward extendingportion 60 of the inner container'scollar 56. The fins deflect as they come in contact with the interior surface of thecollar 56 and create a friction fit there between. In alternate embodiments, thefriction ring 40 may be configured differently but still provide for a friction fit between at least a portion of the inner and outer containers so that they will remain nested until an exterior force is applied to pull them apart. The friction that is created between the inner and outer containers by thefriction ring 40 engaging with thecollar 56 on theinner container 14 is sufficient to prevent the inner andouter containers inner container 14 can be used to heat up food or other consumable materials on a stove or over campfire, and can then be inserted into the insulatedouter container 12 for heat retention and safe carrying of theinner container 14 by the user. Theouter container 12 that holds the heatedinner container 14 full of food or other consumable materials provides an insulated barrier to both retain the heat within theinner container 14 and food, thus keeping its contents hot, while at the same time permitting a user to carry theinner container 14 without worrying about getting burned. - If the user does not intend to immediately consume the food or beverage contained inside the
inner container 14 that is nested within the insulatedouter container 14, the user may sealingly close theinner container 14 by attaching thelid 16 to themouth 46 of theinner container 14. Thelid 16 of the preferred embodiment is screwed onto the top open end of theinner container 14 by inserting thestopper 70 of thelid 16 into themouth 46 of theinner container 14 and turning thelid 16 to mate thethreads 72 disposed in or on the exterior side surfaces of the lid's stopper with the threads formed in theneck 48 of theinner container 14. In an alternate embodiment as previously disclosed, the lid and/or stopper may include bayonet style features that mate with complimentary features located on the inner container, or other such similar mating features that are capable of sealingly closing the inner container with the lid. - In the preferred embodiment, when the
lid 16 is mated to theinner container 14 to sealingly close theinner container 14, thestopper gasket 54 that is disposed in the end of thestopper 70 is seated against therigid sealing surface 52 in thetransition zone 50 of theinner container 14 to form a liquid tight seal there between. In this manner the food and/or beverages contained within theinner container 14 are prevented from leaking out of theinner container 14. In addition, because thestopper 70 includes a block ofinsulation 72 encased within thestopper 70, the act of sealingly mating thelid 16 to theinner container 14 further provides additional heat retention for the food and/or beverage contained therein. - In addition, when the
lid 16 is mated to theinner container 14, thebackup gasket 68 that extends downward from the free end of thesidewalls 60 of thelid 16 is pressed against an exterior surface of thecollar 58 extending from theinner container 14 and forms a liquid tight seal there between. In this manner, should thestopper gasket 54 ever be damaged or wear out over time through excessive or improper use permitting the hot food or beverage to leak into thelid 16, thebackup gasket 68 provides an additional seal that will prevent the hot food or beverages from leaking past the lid and potentially burning the user, for example when transporting the insulatedfood jar assembly 10. - Of course, the insulated
food jar 10 may be used to store and transport chilled foods or beverages which are to be consumed in a chilled state or which are to be heated prior to consumption. The presentfood jar assembly 10 has particular utility when used to store or transport foods or beverages that are chilled during storage and transport and then, prior to consumption, the food or beverage is heated while still in theinner container 14, such as by heating the inner container on a stove or campfire. It is therefore unnecessary to transfer the food or beverage from an insulated transport container to a different container for heating. - The insulated
food jar assembly 10 includes grip features that are decorative as well as useful when opening thefood jar 10. For example, thebase 32 of theouter container 12 has grip contours that aid the user in obtaining a slip-free grip on the outer container during removal of thelid 16 from thejar assembly 10 and/or during removal of theinner container 14 from theouter container 12. Thelid 16 has agrip contour 76 that likewise provides a decorative feature that also assists the user in a slip-free grip of thelid 16 during removal of thelid 16 from theinner container 14.
