The present technology relates to the field of food storage containers.
There are a great variety of containers for household use that are designed for the storage of foods or liquids. Moreover, many food storage containers are designed to thermally insulate the contents of the container in order to maintain a hot or cold temperature of the contents for a period of time. Containers such as coolers or thermoses can keep their contents either hot or cold, but do not have the ability to maintain the temperature for both hot and cold contents simultaneously.
Similarly, containers such as “bento-box” styled lunch-boxes do not provide thermal insulation among their different compartments. That is, such containers are designed to store food items in the various compartments at substantially the same temperature—either all hot or all cold by utilizing a cold pack or an insulated bag that maintains the same desired temperature in the entire container and its various compartments within. If a user wishes to store both hot and cold food items, separate containers are needed.
Consequently, there is a need for a food storage container having compartments that are thermally insulated from each other. A container having two or more thermally insulated compartments can facilitate storage of hot and cold items within a single container.
Embodiments of the present technology address deficiencies of the art in respect to food storage containers. The present technology permits storage of food items having different temperatures in a single container. The container can provide various compartments that are thermally insulated from each other to facilitate storage of hot items in a compartment that is adjacent to cold items.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the scope of the disclosure.
The features and advantages of the disclosure can be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the disclosure will become more fully apparent from the following description and appended claims, or can be learned by the practice of the principles set forth herein.
For example, sidewalls 102a, 102b and bottom wall 102c can each include or consist of a double-wall vacuum insulated barrier that provides thermal insulation to the interior volume of container 100. Alternatively, sidewalls 102a, 102b and bottom wall 102c can each include a barrier that is infused with a thermally insulating material such as polyurethane foam or a material having similar properties. In another embodiment, sidewalls 102a, 102b and bottom wall 102c can be a single material having sufficient thickness to provide thermal insulation.
The interior volume of container 100 can be divided into one or more interior compartments 106a, 106b, 106c by one or more interior walls 104. Although container 100 is illustrated having three rectangular interior compartments 106a, 106b, 106c, those skilled in the art will recognize that the number of interior compartments and the shape of the interior compartments can be changed in accordance with the technology disclosed herein.
Interior walls 104 can have thermal and/or radiant energy transmission deterrence properties designed to provide thermal insulation between interior compartments 106a, 106b, and 106c. Thermal insulation provided by interior walls 104 can allow each interior compartment 106a, 106b, and 106c to maintain the temperature of items placed within the respective interior compartment, whether that temperature is elevated or reduced in relation to the temperature of an item placed in an adjacent interior compartment. Accordingly, interior compartments 106a, 106b, and 106c can be utilized to simultaneously maintain the temperature of both hot and cold food items within the container 100.
In one embodiment, each of interior walls 104 can be formed with the same construction as sidewalls 102a, 102b and bottom wall 102c. That is, interior walls 104 can include or consist of double-wall vacuum insulated barriers that provide thermal insulation between interior compartments 106a, 106b, and 106c. Alternatively, interior walls 104 can each include or consist of a barrier that is infused with a thermally insulating material such as polyurethane foam or a material having similar properties.
In one embodiment, interior walls 104, sidewalls 102a, 102b, and bottom wall 102c of container 100 are all formed as a single structure having a unitary construction. A unitary arrangement for container 100 can provide a stable configuration for hot and cold items. For example, hot soup can be stored in same container as a cold salad while the items keep their respective temperatures and do not interfere with each other, and without the need to have another container with a separate lid that has to be attached to or incorporated with the primary container.
Container 100 can also include a lid or cover 108. Cover 108 can facilitate opening and closing a top portion of container 100 and provide protection and insulation to each of compartments 106a, 106b, and 106c. In one embodiment, cover 108 can be attached to the base portion of container 100 by way of a hinge or some other mechanical member that facilitates movement between open and closed positions for cover 108. In another embodiment, cover 108 can be a separate structure that is detached from the base portion to open container 100 and is attached for closing container 100. A single lid or cover 108 for container 100 is advantageous because it can be opened or removed in a manner that provides access to all items simultaneously and therefore avoids risk of spills caused by having to remove additional covers and/or detach/re-attach other compartments.
Cover 108 can be secured in a closed position by components such as clips, zippers, latches, clasps, fasteners, tongue/groove, or some other mechanical component(s) providing similar functionality. In some embodiments, cover 108 can include one or more handles to facilitate opening and closing cover 108 and/or to facilitate carrying container 100 when cover 108 is in a closed position. Alternatively, one or more handles can also be placed on the exterior portion of one or more of sidewalls 102a, 102b.
Cover 108 can be constructed to provide thermal insulation in order to maintain the temperature of items placed in the interior volume of container 100. For example, cover 108 can be constructed of a double-wall vacuum insulated barrier that provides thermal insulation to the interior volume of container 100. Alternatively, cover 108 can include or consist of a barrier that is infused with a thermally insulating material such as polyurethane foam or a material having similar properties.
Cover 108 can include one or more channels or grooves 110 configured for engagement with the top peripheral portion of sidewalls 102a, 102b or interior walls 104. In some embodiments, grooves 110 can be configured to include a gasket or seal for mating between cover 108 and sidewalls 102a, 102b as well as interior walls 104. The gasket or seal displaced along grooves 110 can be configured to prevent leakage of fluid among or between internal compartments 106a, 106b, 106c as well as preventing leakage of fluid to the outside of container 100.
Container 100 can be constructed from one or more materials suitable for providing thermal insulation among internal compartments 106a, 106b, and 106c as well as thermal insulation from ambient temperature, as described herein. For example, container 100 can be constructed from metal or a metal alloy such as stainless steel, plastic materials, or a combination thereof.
As illustrated, interior wall 204 includes two vacuum insulated barriers that are adjacent to one another. Alternative embodiments having interior wall 204 with different numbers or types of thermal barriers are also contemplated herein. Similarly, as illustrated in
Container 200 can also have lid or cover 208 that can be configured to open and close container 200. Cover 208 can include one or more channels or grooves 210 that can have a seal or gasket 212 displaced within. Grooves 210 can be designed to align with the top of sidewalls 202a, 202b and also with the top of interior wall 204 such that when cover 208 is in a closed position gasket 212 provides a leak-proof seal to each of interior compartments 206a, 206b. The shape of grooves 210 can be designed to complement the shape of the top of sidewalls 202a, 202b and interior wall 202.
Cover 208 can be securely fastened in the closed position by using clips 214a, 214b. Other mechanical components providing similar functionality can be used in alternative embodiments. Cover 208 can also be designed to have a top surface that complements the bottom of container 200. For example, some embodiments of cover 208 may include one or more protrusions 216a, 216b designed to facilitate stacking of one or more containers 200. That is, the dimensions or area of bottom wall 202c can be designed to fit on top of cover 208 and protrusions 216a, 216b can keep the stacked container from slipping or falling away.
In some embodiments, interior compartments 306a, 306b, and 306c can include one or more protrusions 312 configured to receive one or more removable inserts 314. Removable insert 314 can be used to provide one or more barriers within interior compartments 306a, 306b, and 306c. For example, removable insert 314 can be used to keep two food items that are stored within the same interior compartment from touching or mixing with each other. In some embodiments, removable insert 314 can be positioned to create the area for a standard soda can and keep it from rolling around within the interior compartment 306c.
In some embodiments, protrusions 312 can be configured as recessed channels within each of compartments 306a, 306b, 306c. Removable insert 314 can have a corresponding length that is slightly longer than the width of its respective compartment such that it is secured within the recessed channels. In some embodiments, removable insert 314 can be configured to traverse its respective interior compartment in any direction; e.g. horizontal or vertical position.
Container 400 can also include a gasket 404 and a removable cover 406. Gasket 404 can be installed along the perimeter of cover 406 and along interior channels that coincide with partitions in the interior of base 402. Gasket 404 can be a single gasket having the shape depicted or it can be several gaskets corresponding to the various compartments within base 402. In some embodiments, cover 406 can include a groove that facilitates installation of gasket 404.
The interior volume of container 500 can be divided into one or more interior compartments 506a, 506b, 506c by one or more interior walls 504. Interior walls 504 can have thermal and/or radiant energy transmission deterrence properties designed to provide thermal insulation between interior compartments 506a, 506b, and 506c. Thermal insulation provided by interior walls 504 can allow each interior compartment 506a, 506b, and 506c to maintain the temperature of items placed within the respective interior compartment, whether that temperature is elevated or reduced in relation to the temperature of an item placed in an adjacent interior compartment.
Sidewalls 502a, 502b and interior walls 504 can each include protrusion 508 that extends inwardly to container 500. Protrusion 508 can be used to form a ledge or ridge along the interior perimeter of each of the compartments within container 500 which can engage with or otherwise support a lid or cover (not illustrated).
Lid 600 can also include a gasket 610 that is installed along the perimeter of lid 600 as well as the perimeter of each compartment zone 602, 604, 606. In some embodiments, lid 600 can include one or more grooves that facilitate installation of gasket 610. The grooves can be formed along the outside of each of the compartment zones and extend between the zones along the channels in between the zones, such as the channel between compartment zone 604 and compartment zone 606.
Lid 600 can be formed from any material suitable for providing thermal insulation. For example, lid 600 can be constructed from metal or a metal alloy such as stainless steel, plastic materials, or a combination thereof. Lid 600 may also include portions made of foam, rubber, or some other resilient material to facilitate a secure fit and to easily engage/disengage with a container bottom.
Protrusion 710 can be used to form a ledge or support member that mates with a lid or cover such as, for example, the cover illustrated in
