This disclosure relates generally to portable insulated containers for objects, such as shipping containers for food and/or beverages.
It is often desirable to ship food and/or beverages that are required to be maintained within a specified or predetermined temperature range. Exposure, particularly to temperatures outside the predetermined temperature range, may result in the degradation or spoilage of the food and/or beverage being shipped. For example, it may be desirable to maintain bottles of wine within a preferred temperature range during shipping, such as between 35° F. and 70° F. to prevent degradation of the wine. It may also be desirable to provide some degree of protection to food or beverage being shipped, such as protection from impact.
Currently available shipping containers may suffer from one or more disadvantages, such as requiring large volumes of ice or other coolant to maintain the temperature of the shipped food and/or beverage within the predetermined range. Some products may not be typically shipped during certain times of the year, such as summer when the environmental temperature may be too warm, or winter, when the environmental temperature may be too cold. Even during more moderate environmental temperatures, food and/or beverages may not be shipped if the expected delivery time exceeds the capacity of the shipping container to maintain the predetermined temperature range. In addition, the placement of the coolant within current shipping containers may lead to the food and/or beverage in different positions within the shipping containers being exposed to a variety of temperature histories.
It is therefore desirable to be able to ship food and/or beverages in a container providing more even temperature distribution within the cavity or chamber and with a high degree of insulation to better maintain the temperature within the chamber within a predetermined temperature range.
Insulated shipping containers are used for a variety of purposes and in conjunction with a variety of activities. A container may be insulated to assist in keeping one or more items cool, cold, frozen, warm, or hot. The 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 container for keeping the contents cool, it should be understood that the techniques and features disclosed herein are applicable to other types of storage containers or temperature control containers. The containers disclosed herein may be configured to be carried or transported in a plurality of manners or configurations.
In one example, a portable insulated container is used for transporting a plurality of bottles wherein the plurality of the bottles includes bottles having two or more bottle shapes and includes bottles having two more bottle sizes. The portable insulated container includes an outer shell and a temperature control pack. The portable insulated container also includes a first insert portion that fits inside the outer shell and a second insert portion that also fits inside the outer shell and is configured to engage with the first insert portion to form a plurality of insulated cavities. The plurality of insulated cavities include a temperature control pack cavity for receiving the temperature control pack along with three or more separate bottle storage cavities. Each of the three or more bottle storage cavities is configured for receiving a respective one of the plurality of the bottles and each of the three or more bottle storage cavities is configured for receiving at least two of the bottle sizes and at least two of the bottle shapes. Each of the three or more bottle storage cavities may also be equidistant from the temperature control pack cavity.
In another example, a portable insulated shipping container includes an insulated body having an internal cavity configured for storing items, an insulated lid configured to releasably engage the insulated body to close the internal cavity, and an insert positioned within the internal cavity. The insulated cavity is internal cavity at least partially bounded by a bottom and a plurality of walls. The insert includes three or more cavities each configured to receive an item. The three or more cavities are spaced around a central temperature control cavity configured to receive at least a portion of a temperature control pack. A distance between the central temperature control cavity and each cavity of the three or more cavities is the same for each cavity.
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.
In some embodiments, one or more walls 114 each include a lower portion 118 and an upper portion 120. In some embodiments, lower portion 118 may be set back or tapered in a direction towards bottom surface 112, allowing at least a portion of lower portion 118 to nest inside the corresponding upper portion 120 of a second container 100. By nesting a portion of lower portion 118 into a second container 100, the amount of space necessary to store and/or ship empty containers 100 may be reduced.
Body 110 includes one or more latch receivers 122 for releasably receiving a latch 124. Latch 124 illustratively extends through a lid receiver 126 in lid 130 and latch receiver 122 in upper portion 120 of body 110 to releasably attach lid 130 to body 110.

Tray 150 includes an upper surface 154 into which the cavities 152 are formed. Each cavity 152 extends from the upper surface 154 along one or more cavity walls 156 to a bottom 158. In the embodiment illustrated in
Cavities 152 are arranged around a central temperature control cavity 160, which may also be referred to as temperature control pack cavity. Temperature control cavity 160 includes one or more walls 162, each extending from upper surface 152 of tray 150 to a bottom 168.
In the illustrated embodiment, tray 150 includes six cavities 152, namely cavities 152A-152F, and temperature control cavity 160 includes six corresponding walls 162, namely walls 162A-162F (see
Each cavity 152 has a diameter, indicated in
Each cavity 152 is separated from an adjacent cavity 152 by a distance, indicated in
In some embodiments, d2 is about the same size or smaller than d1. In some embodiments, a ratio of d1 to d2 is 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 8:1, 10:1, or greater, or between any two of the foregoing values, such as 1:1 to 10:1 or 4:1 to 10:1.
Each cavity 152 is separated from the closest wall 162 of the central temperature control cavity 160 by a distance, indicated in
In some embodiments, the distance d3 for each cavity 152 is the same for all cavities 152 in tray 150. Without wishing to be held to any particular theory, Examples 1-3 below illustrate that providing a consistent distance d3 between all cavities results in a more consistent temperature for all items positioned within the cavities 152 compared to geometries in which d3 differs among cavities 152. Examples 1-3 below further illustrate that providing a consistent distance d3 between all cavities results in longer period of temperature control compared to geometries in which d3 differs among cavities 152.
In some embodiments, d3 is about the same size or smaller than d1. In some embodiments, a ratio of d1 to d2 is 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 8:1, 10:1, or greater, or between any two of the foregoing values, such as 1:1 to 10:1 or 4:1 to 10:1.
In some embodiments, d3 is about the same size as d2. In some embodiments, d3 is larger than d2. In some embodiments, d3 is smaller than d2. In some embodiments, a ratio of d2 to d3 is 10:1, 8:1, 6:1, 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:8, 1:10, or between any two of the foregoing values, such as 10:1 to 1:10 or 2:1 to 1:2.
In some embodiments, tray 150 includes one or more additional cavities 164 not arranged around central cavity 160. Additional cavities 164 may be used for storing other items for shipping, such as items that require less, little, or no temperature control during shipping as compared to the items shipped in cavities 152. The walls forming additional cavities 164 may be sized to snugly position tray 150 within base 110 of container 100, preventing tray 150 from moving during shipping.
In some embodiments, tray 150 includes one or more fins 166 each extending outward from a cavity 152, such as opposite cavities 152C and 152F. Fins 166 may be sized to snugly position tray 150 within base 110 of container 100, preventing tray 150 from moving during shipping.

As illustrated in
Cover 180 includes an upper central temperature control cavity 188, which may also be referred to as temperature control pack cavity. Upper temperature control cavity 188 illustratively has a shape corresponding to the shape of the central temperature control cavity 160 of tray 150.
In some exemplary embodiments, such as that illustrated in
In some exemplary embodiments, cover 180 includes one or more handles 192 to assist in removing cover 180 from tray 150.
As illustrated in
Referring next to
Temperature control pack 200 includes a lower portion 202 proximate bottom end 204 and an upper portion 206 proximate top end 208. Lower portion 202 of temperature control pack 200 illustratively has a cross-sectional area corresponding to the cross-section of central temperature control cavity 160 of tray 150, allowing at least a part of lower portion 202 of temperature control pack 200 to be received within central temperature control cavity 160. Upper portion 206 of temperature control pack 200 illustratively has a cross-sectional area corresponding to the cross-section of upper central temperature control cavity 188 of cover 180, allowing at least a part of upper portion 206 of temperature control pack 200 to be received within upper central temperature control cavity 188.
Temperature control pack 200 includes one or more walls 210. In some embodiments, temperature control pack 200 includes the same number of walls as central temperature control cavity 160 of tray 150 and upper central temperature control cavity 188 of cover 180. In other embodiments, temperature control pack 200 includes a single wall and has a circular cross-section configured to fit within central temperature control cavity 160 of tray 150 and upper central temperature control cavity 188 of cover 180.
In some embodiments, temperature control pack 200 is releasably affixed to tray 150 or cover 180 with one or more latches, clasps, fasteners, clips, levers, or detents (not shown in
An interior of temperature control pack 200 includes one or more temperature control substances. Exemplary temperature control substances include ice packs, cold packs, water, gel packs, instant ice packs, ice, dry ice, hot packs, and/or other thermal items and mixtures thereof. In some embodiments, the temperature control substance may be based on one or more of the substances thermal characteristics, thermal profiles, thermal mass, non-toxicity, or other suitable characteristics.
In some embodiments, temperature control pack 200 is a refillable container configured to be filled with liquid water that can be frozen to ice. In some embodiments, temperature control pack 200 includes one or more indicia 212, 214 indicating a level to which the temperature control pack 200 should be filled. In one exemplary embodiment, temperature control pack 200 may be filled with water to indicia 212 and frozen to provide a first temperature control mass, or temperature control pack 200 may be filled with water to indicia 214 and frozen to provide a second temperature control mass. The first temperature control mass associated with indicia 212 may be less than the second temperature control mass associated with indicia 214. Advantageously, this may allow a user to provide only the minimum weight in temperature control pack 200 to ship container 200 using a first shipping service, such as a 2 day shipping service, or more ice in temperature control pack for longer temperature control if a slower shipping speed is to be used, such as a 3, 4, or 5 day ground shipping service.
In some exemplary embodiments, it may be desirable to use the temperature control pack 200 to maintain a predetermined temperature range that is cooler than an external temperature. In these embodiments, the temperature control pack may include a cooling temperature control substance, such as ice.
In some exemplary embodiments, it may be desirable to use the temperature control pack 200 to maintain a predetermined temperature range that is warmer than an external temperature. In these embodiments, the temperature control pack may include a warming temperature control substance, such as warm water, hot water, or a heat generating chemical.
In some exemplary embodiments, it may be desirable to use the temperature control pack 200 to maintain a predetermined temperature range against fluctuations in the external temperature. In these embodiments, the temperature control pack may include a temperature control substance with a high phase change energy, such as ice or liquid water. In some embodiments, the thermal mass of temperature control pack 200 helps container 100 absorb thermal shocks, such as temporarily low and/or high environmental temperatures, to maintain the contents of the container 100 within the predetermined temperature range for a longer period of time.
In some embodiments, temperature control pack 200 is removed from tray 150 and/or cover 180 before heating or cooling the temperature control substance. In other embodiments, temperature control pack 200 is affixed to tray 150 and/or cover 180 when the temperature control substance is heated or cooled.
An exemplary method of using the container 100 is provided. The shipping insert 140 is positioned within internal cavity 128 of body 110. In some embodiments, the shipping insert 140 is permanently attached in the internal cavity 128. One or more items to be shipped, such as six bottles of wine, are each placed into a corresponding cavity 152A-152F of tray 150. The temperature control pack 200 is positioned in the central cavity 160. The cover 180 is then placed onto the tray 150, such that an upper portion of the item to be shipped is received within the corresponding upper cavity 182A-182F. The lid 130 is releasably secured to the body 110.
There are many different types, shapes, and sizes of bottles. Even within the field of wine bottles, there are many shapes and sizes. Similar shapes or styles of bottles are often associated with certain varieties of wine. However, even for bottles of a specific capacity that are often associated with a certain variety of wine, there are often still minor variations in the bottle shapes. For this reason, it is challenging to design a universal, or semi-universal, shipping container that contacts a variety of bottles on many or all surfaces to completely eliminate movement of the bottles in the cavity. While eliminating bottle movement in a universal or semi-universal cavity will typically not be possible for all bottles, providing a design which reduces or minimizes the movement of various bottles still provides a significant benefit. If the shipping container is dropped or impacted, the distance the bottle travels within the cavity is proportional to the likelihood that the bottle is damaged and/or the cavity or container is breached by the bottle. Therefore, reducing the amount of potential movement significantly reduces the chance of damage.
In order to accommodate a variety of bottle shapes and sizes, the bottle cavities must be made large enough and/or with a shape that is accommodating of a variety of bottle shape variations. While each cavity may not be able to accommodate all of the bottle shapes and sizes under consideration, each cavity may be able to accommodate a subset of the bottle shapes and sizes under consideration. In order for this to be possible, the cavity will not be able to hold all of the types of bottles snugly and most or all of the bottles will have some degree of potential movement within the cavity. However, including stops or other cavity features that reduce the amount of movement or travel for various bottles improves the performance of the container in shipping and handling since less travel within the cavity reduces the likelihood that the bottle is damaged and/or the cavity, container, or insert is damaged by the bottle.
The bottle storage cavity illustrated in
In one example, portable insulated container 100 is used for transporting a plurality of bottles wherein the plurality of the bottles includes bottles having two or more bottle shapes and includes bottles having two more bottle sizes. Portable insulated container 100 includes an outer shell and a temperature control pack. The portable insulated container also includes a first insert portion that fits inside the outer shell and a second insert portion that also fits inside the outer shell and is configured to engage with the first insert portion to form a plurality of insulated cavities. In
There may be one or more of larger lower cavity 159 in tray 150 along with multiple lower cavities 152, and/or lower cavities of other sizes. If lower cavity 159 was used in every instance of a cavity in a particular shipping container, the bottles in those cavities would have less protection and/or more movement because of the large area. In this way, a single container can accommodate even more bottle shapes or sizes by having a variety of cavity sizes. As illustrated, sixth bottle 2110 contacts or is in close proximity to first stop 1530 thereby reducing the movement of sixth bottle 2110 in the cavity. Sixth bottle 2110 may also contact fourth stop 1540.
In some examples, cover 180 may also contain upper cavities of different sizes. For example, cover 180 may contain one or more upper cavities, which may be paired with any lower cavity, to accommodate a larger bottle, a bottle with a larger neck, a bottle with a larger decorative cork, a bottle with a champagne-type cork, and/or a bottle with a cork cage. Any variety of combinations of upper cavities and lower cavities are possible to form cavities of various sizes and having stops with various sizes and locations.
In other examples, one or more removable inserts may be used to temporarily reduce the size of any of the cavities disclosed herein. A removable insert may be placed in one or both of upper cavity 182 and lower cavity 152 to temporarily better fit a bottle having a smaller size and/or different shape and then later removed to return the cavity to its original size.
The ability of a variety of geometries to maintain a predetermined temperature range was investigated. Referring to
Example 1. Referring first to
Example 2. Referring next to
Example 3. Referring next to
For each example, six bottles of wine were prepared with a thermocouple disposed in the liquid. The starting temperature of all bottles was 55° F. One bottle was placed in each opening and a fully frozen ice pack was placed in the temperature pack opening. The layers of each rig were assembled as illustrated in
As indicated in table 1, the greatest temperature difference between bottles was observed with Example 1, while the smallest temperature difference between bottles was observed with Example 3.
In addition, the hexagonal arrangement of Example 3 provided the longest time for all bottles to stay below 70° F., even though less ice was used in Example 3 (6 pounds) compared to Examples 1 and 2 (7 pounds).
Overall, the hexagonal arrangement of Example 3 in which the wine bottles were received in cavities equally spaced from each other and equally spaced around the central ice cavity provided the highest temperature consistency between the six tested bottles. The hexagonal arrangement also provided the longest time before any bottle reached the predetermined temperature of 70° F., even though Example 3 used 1/7 (˜14%) less ice than Examples 1 or 2.
