This disclosure relates generally to portable insulated storage containers for storing or shipping objects, such as food and/or beverages.
It is often desirable to bring food or beverages when traveling or when participating in remote leisure activities. Often, the food may be perishable and the ambient temperature may be high (for instance, at a beach location), so it may be desirable to keep the perishable food in a temperature controlled environment to avoid spoiling. Similarly, beverages, such as canned or bottled beverages, may also be consumed, and it is desired to keep such beverages cool until consumption. Storage containers, insulated storage containers, coolers, and/or insulated shipping containers may also be used for a variety of other purposes or activities including hunting, fishing, camping, medical purposes, general storage, grocery delivery, meal kit shipping, other food delivery, and/or other business or personal purposes.
Ice packs, cold packs, and/or cooling packs may be placed in an interior portion of a storage container defined by the side walls and bottom wall to keep the interior portion of the storage container at a desired temperature that is lower than the ambient temperature. In other situations, storage containers of the type described herein may be used to keep one or more items warmer or hotter than the ambient environment. In many cases, the storage container may contain various items that have various temperature needs. It is therefore desirable to be able to configure the storage container to accommodate these varied needs, as well as to be able to easily reconfigure the storage container for subsequent uses which have different temperature or temperature configuration needs.
Storage containers are used for a variety of purposes and in conjunction with a variety of activities. A storage container may be insulated to assist in keeping one or more items cool, cold, frozen, warm, or hot. The storage container may also be used to protect one or more items from damage, bumps, scratching, impact, water, rain, snow, mud, dust, dirt, light, visibility, theft, chemicals, and/or contaminants. While most of the examples discussed herein are discussed with respect to a “cooler,” it should be understood that the techniques and features disclosed herein are applicable to other types of storage containers or temperature control containers. Further, storage containers of the type disclosed herein may be used for storage or transportation purposes and need not necessarily include insulating characteristics. The storage containers disclosed herein may be configured to be carried or transported in a plurality of manners or configurations.
In one example, a portable insulated storage container includes an insulated body, an insulated lid, and a retainer. The insulated body has an internal cavity for storing one or more items. The internal cavity is selectively and reversibly configurable into two or more storage areas. The insulated lid engages the insulated body to close the internal cavity. The insulated lid includes two or more receptacles each configured for receiving a cold pack or other thermal device. Each of the two or more receptacles aligns with a respective one of the two or more storage areas when the insulated lid engages the body. The retainer removably retains the cold pack in one of the receptacles.
Other variations and embodiments are possible, including variations and embodiments which do not necessarily include all of the elements described above and/or variations and embodiments which may include additional elements.
Body 110 and/or lid 120 may be rigid or may contain portions that are flexible, bendable, soft, compliant, stretchable, and/or compressible. In some cases, one or more portions of cooler 100 may be partially or fully collapsible when not in use. Various portions of cooler 100 may be attached using one or more methods including sewing, gluing, adhesive, electro-welding, thermoplastic welding, co-molding, melting, and/or fasteners. Lid 120 may be fully removable from body 110 (as illustrated in
Body 110 and/or lid 120 also include one or more information panels, such as label receiver 160. Label receiver 160 may be a pouch, pocket, slot, or surface for storing or displaying information about the contents of cooler 100 and/or shipping information for cooler 100. Label receiver 160 may include a substantially clear window or a substantially transparent window. The contents information and/or shipping information may be removable, changeable, or replaceable. One or more parts of cooler 100 and/or cooler 100 may be waterproof, water-resistant, abrasion resistant, tear resistant, and/or puncture resistant.
Latches 150 may provide a closure that is waterproof, water-resistant, childproof, child resistant, animal proof, and/or animal resistant. Latches 150 may include one or more components made of plastic, metal, wood, ceramic, rubber, and/or silicone. Further, latches 150 may include a locking mechanism or may include an interface for use with one or more locks or access control devices, such as an electronic lock or a seal which indicates opening or tampering. One or more gaskets or seals may be used between lid 120 and body 110.
Cooler 100 may also include one or more attachment areas or attachment points for removably attaching one or more accessories or other items to cooler 100. Attachment points may include any of a variety of attachment mechanisms, structures, elements, or features including any described in U.S. patent application Ser. No. 15/398,468, filed Jan. 4, 2017, which is hereby incorporated by reference in its entirety.
Beneficially, different types of items with different requirements can be stored in each of the different storage areas. The requirements of the items may vary based on temperature requirements. In one example, one storage area may be used for frozen items, while the second is used for cold beverages, and the third is used for items which must kept cool but may be sensitive to extreme cold, such as sensitive vegetables. A grocery delivery company or meal kit company may place different products, groups of products, or ingredients in different storage areas or compartments that will be configured for different temperatures. The features described herein enable the temperatures of the individual storage areas of cooler 100 to be individually planned and managed. The features also allow cooler 100 to be easily reconfigured for different storage or shipment needs where the temperature needs are different and/or the quantities of goods in any particular temperature category are different. In this way, cooler 100 may be repeatedly reused while being adapted or configured to be better suited for each use.
In some examples, one or more of the storage areas or compartments may be used for items that preferably remain at room, neutral, or outside temperature. In other examples, one or more of the storage areas or compartments may be used for items that must be kept warm or hot relative to other items. In yet other examples, various areas may be used for pharmaceuticals or other medical items that have different temperature requirements. The different storage areas or compartments may also be used for items or groups of items that have varying levels of sensitivity to humidity or liquid.
In some examples, one or more ice packs or hot packs may be permanently, or semi-permanently, attached or integrated into body 110 and/or lid 120. In these examples, the entire body 110 and/or lid 120 may be heated, cooled, or frozen before use. For example, a body 110 may be packed with items and then a pre-frozen lid that includes ice packs may be attached.
In one example, dry ice may be used in receptacle 122 to keep items in storage area 111 frozen, while a cold pack is used in receptacle 124 to keep items in storage area 112 cold, but not frozen. At the same time, a different type of cold pack or a smaller cold pack may be used in receptacle 126 to keep items in storage area 113 cool, but not as cold as those in storage area 112. In another example, different quantities of a same cold pack may be used in each of the receptacles to maintain different temperature targets of each storage area. The number or type of cold packs associated with each storage area may also be selected, at least in part, by the quantity, initial temperature, and/or thermal mass of the items being placed into each storage area.
In some cases, one or more other environmental control items may be included in one or more of the receptacles, such as a desiccant or an odor control device.
In other examples, one or more of the storage areas may have no associated cold packs or other cooling devices. Grocery delivery or meal kit providers may utilize these features to keep different items, or groups of items, closer to their preferred shipping or storage temperatures. For example, some items may not need any cooling or refrigeration and concentrating the cooling packs to the storage areas where cooling is needed may improve performance and/or reduce the size or quantity of cooling packs which are needed. In some cases, one or more of the cooling pack receptacles and/or storage areas may be left empty for a particular shipment.
Beneficially, receptacles 122-126 are located in lid 120 such that cool or cold air from them naturally drops, moves, or migrates down to the items in the respective storage areas below through normal convection processes. In many situations, this provides an improvement over packing items on top of ice or cold packs and also allows the ice or cold packs to be replaced without removing the items. Locating the receptacles in the lid also provides efficiencies and improvements for assembly lines where the receptacles of lid 120 can be populated and readied separately from the packing of items into body 110 before body 110 and lid 120 come together. They can also be separately processed and/or cleaned when cooler 100 is returned to a provider.
Each of receptacles 122-126 may also include or utilize a retainer, such as retainers 123, 125, and 127, for removably retaining one or more ice packs, cold packs, gel packs, instant ice packs, ice, dry ice, hot packs, and/or other thermal items in the associated receptacle. Each retainer may include a number of holes for allowing temperature transfer and air movement. The retainer may be configured as a sheet with holes, a mesh, a screen, a grate, a net, a lattice, or any other structure which will retain items in the receptacles while allowing airflow and/or convection. In some examples, the retainer may be made from a stretchable material, such as silicone, which is stretched and attached over hooks or other attachment features such that the tension keeps it in place until it is intentionally removed. In some cases, the number and/or sizes of the holes in the retainer may be selected in order to control the cooling effect and/or lifetime of the retained cooling pack.
In some examples, each retainer may snap into place or may provide access to the associated receptacle using one or more hinges or hinging elements. Further, a retainer may engage the receptacle using any type of fastener, clip, buckle snap, rotating pin, interference fit, bending, flexing, adhesive, magnetic elements, threaded elements, hook and loop fastener, or other attaching means to temporarily and removably hold the retainer in place.
While the storage areas in
In some examples, one or more of the storage areas may also include a receptacle and/or grate or retainer in or near a bottom portion of the storage area, similar to the receptacles in lid 120, for adding additional cold packs, ice packs, or other thermal elements. For example, one or more of grates 183, 185, and 187 may be used to separate stored items from ice, water, and/or cold packs. Grates 183, 185, and 187 may be optional, adjustable to different height levels, include different sized holes or ports, and/or include no holes or ports.
In some configurations, one or more of body 110 and lid 120 may have a port or aperture that extends through one of the surfaces, such as a wall of body 110. The port may be used for draining liquid and may include a lid or cap. In other configurations, the port may be fitted with a valve for releasing or equalizing gas pressure, purging, or filling with a gas other than air. In some cases, the valve may be a breather valve and may include a filter. In other cases, the valve may be a one way valve.
In
Beneficially, bins 131 and 132 may also provide better isolation between storage areas. In addition, bins 131 and 132 may be separately packed, filled, and/or temporarily stored before being placed into body 110 for shipping or transport. This flexibility allows high volume assembly and fulfilment operations to pack, fill, and handle bins of varying contents and insert them into body 110 at or near the end of assembly operation without having to move or carry body 110 through the entire packing operation and without having to bring the various bins which may make up a shipment together until at or near the end of the assembly operation or process. This may allow individual bins to be packed or stored in different locations until they are used.
Bins 131 and 132 may be used with cooler bodies of various sizes. For example, bin 131 or 132 may be used with a cooler body that holds or accommodates up to 2, 3, 4, 5, 6, 7, 8, 9, 10, or any other number of bins. In some cases, bins of different sizes may also be used. In one example, referring to
Bin 131 and/or bin 132 may or may not have insulated walls and may have varying amounts of insulation relative to each other. Similarly, bin 131 and/or bin 132 may have some walls that are insulated and some that are not such that when insulation is not duplicated. For example a side wall of bin 131 may not have insulation such that when it is placed next to the complementary insulated wall of bin 132 there are not two layers of insulation. Other configurations and combinations are possible.
The use of bins may also provide benefits relative to cleaning and sanitation. If food storage/contact is limited to bins and lid 120, body 110 may be subject to less stringent cleaning, sanitation, and/or material requirements. In some configurations, a separate lid may also be used with each of the bins to provide further isolation and/or to also subject lid 120 to the less stringent cleaning or sanitation requirements.
In addition to the primary internal storage areas or compartments, cooler 100 may also include one or more other storage areas, storage pockets, or storage compartments for carrying other items. Cooler 100 may also include one or more other accessories, such as a rechargeable battery, a solar cell, a light, a liquid storage bladder, a first aid kit, a toolkit, and/or one or more thermometers for indicating a temperature of one or more of the storage areas. In some configurations, one or more of the additional pockets, storage compartments, and/or dry storage areas may be accessible at an interior surface of cooler 100. Other configurations are possible.
Body 110 and lid 120 may also have features which allow multiple instances of cooler 100 to be stacked on top each other in a stable manner. These features may include protrusions, divots, fingers, recesses, pins, pockets, grooves, tracks, holes, and/or rails. Further, body 110 and/or lid 120 may have tapered walls such that multiple instances of either may be stacked on each other in a nested fashion for space efficiency when they are not in use.
In addition, cooler 100 may include one or more powered cooling or heating units for assisting in keeping items cold or warm, respectively, before transport, after delivery, and/or for some portion of the shipping process. In other words, the features disclosed herein may be supplemented by a powered cooling or heating unit when power is available and cooler 100 can be attached to the power source. In further examples, cooler 100 may include one or more contained power sources, such as a battery or solar panel, for temporarily providing power to the cooling or heating unit without tethering it to a power source.
Divider 714A further includes vent 721 which allows air to pass through from one side of divider 714A to the other side of divider 714A. Vent 721 may also be referred to as an aperture, a port, an opening, a baffle, a passage, and/or a window. Divider 714A may be installed in cooler 110 of
Divider 714A also includes a door 723, which may also be called a cover. Door 723 slides on slots 725, which may also be called guides, tracks, or rails. Door 723 may be moved or adjusted on slots 725 to expose or cover varying or chosen amounts of vent 721 to either increase or decrease the effect of vent 721. Slots 725 may contain notches or detents to make it easy to get door 723 into a chosen position and to tend to keep it there despite vibration.
It should be understood that vent 721 and door 723 may have a variety of shapes, sizes, configurations, or quantities that provide similar results. For example,
Any of the components disclosed herein may include or may be coated with an anti-microbial and/or anti-viral substance or ingredient.
