INSULATED CONTAINER
An insulated container and method of assembling the same utilize a side insulating member and top and bottom insulating members that define an insulated interior compartment within a container body. The side insulating member is folded into four portions that respectively contact four sides of the container body, while a bottom insulating member is sized to be inserted into the container body after the side insulating member with four edge portions of the bottom insulating member contacting the four portions of the side insulating member, and the top insulating member is sized to contact top edge surfaces of the four portions of the side insulating member. By doing so, enhanced sealing and structural support within the insulated container may be provided.
Insulated containers are used in the storage and transport of goods for which it is desirable to maintain a controlled environment, e.g., to maintain goods at a temperature that is higher or lower than the ambient temperature of the surrounding environment. Worldwide sensitivity to sustainability has also increased interest in reducing the environmental impact of containers and other packaging. In addition, as with many types of containers and other packaging, it is often desirable to minimize material and manufacturing costs, minimize container weight (which can impact shipping costs), and simplify manufacturing, assembly and loading of insulated containers.
Therefore, a continuing need exists in the art for an insulated container that is capable of maintaining a controlled internal environment, and to do so in a cost effective and environmentally conscious manner.
SUMMARY OF THE INVENTIONThe invention addresses these and other problems associated with the art by providing an insulated container and method of assembling the same that utilizes a side insulating member and top and bottom insulating members that define an insulated interior compartment within a container body. The side insulating member is folded into four portions that respectively contact four sides of the container body, while the bottom insulating member is sized to be inserted into the container body after the side insulating member with four edge portions of the bottom insulating member contacting the four portions of the side insulating member, and the top insulating member is sized to contact top edge surfaces of the four portions of the side insulating member. By doing so, enhanced sealing and structural support within the insulated container may be provided.
Therefore, consistent with one aspect of the invention, an insulated container may include a container body including a bottom and first, second, third, and fourth sides, a side insulating member received in the container body and folded into first, second, third, and fourth side portions that respectively contact the first, second, third, and fourth sides of the container body, each of the first, second, third, and fourth side portions including an inwardly-facing surface that faces away from the respective first, second, third, and fourth side of the container body and a top edge surface that faces away from the bottom of the container body, a bottom insulating member contacting the bottom of the container body, the bottom insulating member including an upwardly-facing surface that faces away from the bottom of the container body and an edge surface that circumscribes the upwardly-facing surface of the bottom insulating member and includes first, second, third, and fourth edge surface portions that respectively contact the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member, and a top insulating member including a downwardly-facing surface that faces the bottom of the container body and that contacts the top edge surface of each of the first, second, third, and fourth side portions of the side insulating member.
In some implementations, the bottom insulating member has a length and a width and the top insulating member has a length and a width, the length of the top insulating member is larger than the length of the bottom insulating member, and the width of the top insulating member is larger than the width of the bottom insulating member. Also, in some implementations, each of the first, second, third, and fourth side portions of the side insulating member further includes an outwardly-facing surface that faces toward the respective first, second, third, and fourth side of the container body, where the top edge surface of each of the first, second, third, and fourth side portions of the side insulating member defines a thickness separating the respective inwardly-facing and outwardly-facing surfaces of the respective first, second, third, and fourth side portion of the side insulating member. Further, in some implementations, a perimeter of the top insulating member is substantially coincident with a perimeter defined by the outwardly-facing surfaces of the first, second, third, and fourth side portions of the side insulating member and a perimeter of the bottom insulating member is substantially coincident with a perimeter defined by the inwardly-facing surfaces of the first, second, third, and fourth side portions of the side insulating member.
In some implementations, each of the first, second, third, and fourth side portions of the side insulating member further includes a bottom edge surface that contacts the bottom of the container body. In addition, in some implementations, the container body further includes a closable top, and the top insulating member further includes an upwardly-facing surface that contacts the closable top of the container body when the closable top is closed.
In some implementations, the bottom insulating member is sized and configured such that the edge surface presses the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member against the respective first, second, third, and fourth sides of the container body. In addition, in some implementations, the bottom insulating member is sized and configured such that the edge surface forms a seal with the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member. Moreover, in some implementations, the bottom insulating member is sized and configured such that the edge surface presses the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member to structurally support the side insulating member against the first, second, third, and fourth sides of the container body.
Consistent with another aspect of the invention, a method of assembling an insulated container may include inserting a side insulating member into a container body including a bottom and first, second, third, and fourth sides, the side insulating member folded into first, second, third, and fourth side portions that respectively contact the first, second, third, and fourth sides of the container body when the side insulating member is inserted into the container body, and each of the first, second, third, and fourth side portions including an inwardly-facing surface that faces away from the respective first, second, third, and fourth side of the container body and a top edge surface that faces away from the bottom of the container body, after inserting the side insulating member into the container body, inserting a bottom insulating member into the container body such that the bottom insulating member contacts the bottom of the container body, the bottom insulating member including a upwardly-facing surface that faces away from the bottom of the container body and an edge surface that circumscribes the upwardly-facing surface of the bottom insulating member and includes first, second, third, and fourth edge surface portions that respectively contact the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member when the bottom insulating member is inserted into the container body, and after inserting the bottom insulating member into the container body, inserting a top insulating member into the container body, the top container body including a downwardly-facing surface that faces the bottom of the container body and that contacts the top edge surface of each of the first, second, third, and fourth side portions of the side insulating member when the top insulating member is inserted into the container body.
In some implementations, the bottom insulating member has a length and a width and the top insulating member has a length and a width, the length of the top insulating member is larger than the length of the bottom insulating member, and the width of the top insulating member is larger than the width of the bottom insulating member. Moreover, in some implementations, each of the first, second, third, and fourth side portions of the side insulating member further includes an outwardly-facing surface that faces toward the respective first, second, third, and fourth side of the container body, where the top edge surface of each of the first, second, third, and fourth side portions of the side insulating member defines a thickness separating the respective inwardly-facing and outwardly-facing surfaces of the respective first, second, third, and fourth side portion of the side insulating member. In some implementations, a perimeter of the top insulating member is substantially coincident with a perimeter defined by the outwardly-facing surfaces of the first, second, third, and fourth side portions of the side insulating member and a perimeter of the bottom insulating member is substantially coincident with a perimeter defined by the inwardly-facing surfaces of the first, second, third, and fourth side portions of the side insulating member.
In addition, in some implementations, each of the first, second, third, and fourth side portions of the side insulating member further includes a bottom edge surface that contacts the bottom of the container body. In some implementations, the container body further includes a closable top, and the top insulating member further includes an upwardly-facing surface that contacts the closable top of the container body when the closable top is closed.
Moreover, in some implementations, the bottom insulating member is sized and configured such that the edge surface presses the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member against the respective first, second, third, and fourth sides of the container body when the bottom insulating member is inserted into the container body. Also, in some implementations, the bottom insulating member is sized and configured such that the edge surface forms a seal with the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member when the bottom insulating member is inserted into the container body. In some implementations, the bottom insulating member is sized and configured such that the edge surface presses the inwardly-facing surfaces of the first, second, third, and fourth portions of the side insulating member when the bottom insulating member is inserted into the container body to structurally support the side insulating member against the first, second, third, and fourth sides of the container body.
In addition, in some implementations, the container body further includes a closable top, and the method further includes closing the closable top after inserting the top insulating member into the container body. Also, in some implementations, the top, bottom, and side insulating members define an insulated interior compartment in the container body, and the method further includes inserting an item and a heat or cold pack into the insulated interior compartment after inserting the bottom insulating member into the container body and before inserting the top insulating member into the container body.
These and other advantages and features, which characterize the invention, are set forth in the claims annexed hereto and forming a further part hereof. However, for a better understanding of the invention, and of the advantages and objectives attained through its use, reference should be made to the Drawings, and to the accompanying descriptive matter, in which there is described example implementations of the invention.
Some implementations consistent with the invention may provide an insulated container in which three insulating members are positioned within a container body, such as a corrugated cardboard box, to contact each of the six interior surfaces of the container body to form an insulated compartment bounded on all sides by insulation to assist in controlling the environment within the insulated interior compartment. As will become more apparent below, a side insulating member is folded into four portions that respectively contact four sides of the container body, while a bottom insulating member is sized to be inserted into the container body after the side insulating member with four edge portions of the bottom insulating member contacting the four portions of the side insulating member, and the top insulating member is sized to contact top edge surfaces of the four portions of the side insulating member. By doing so, enhanced sealing and structural support within the insulated container may be provided.
Turning to the Drawings, wherein like numbers denote like parts throughout the several views,
Insulated container 10 also includes a plurality of insulating members, which in the illustrated implementation include a top insulating member 26, a bottom insulating member 28, and a side insulating member 30. In some implementations, it is desirable to include only three insulating members; however, a greater or fewer number of insulating members capable of insulating the six surfaces of the container body may be used in other implementations.
Top insulating member 26 has a length LT, width WT, and thickness TT, while bottom insulating member 28 has a length LB, width WB, and thickness TB. Side insulating member 30 has a length LS, width WS, and thickness TS, and includes four portions 32, 34, 36, 38 that respectively have lengths of L1, L2, L3, and L4, and that are joined by a plurality of fold lines 40. In the illustrated implementation, side insulating member 30 is formed of a single contiguous piece of insulating material such that portions 32, 34, 36, 38 are formed by folding along fold lines 40, although in other implementations the portions may be separate members joined by flexible joints (e.g., using tape), or may be separate members and may not be joined to one another.
In some implementations, insulating members 26, 28, 30 are formed from the same insulating material, such that the thicknesses TT, TB, and TS of insulating members 26, 28, 30 are substantially the same, although in other implementations, different insulating materials and/or thicknesses may be used for insulating members 26, 28, 30. The length and width dimensions of each insulating member 26, 28, 30 in turn are generally selected based at least in part on the dimensions of container body 12.
In some implementations, for example, a friction fit may be desired in order to resist displacement of the insulating members during loading, unloading, or transport of the insulated container, as well as to minimize gaps between the insulating members that could allow for greater heat transfer between the insulated interior compartment and the exterior environment. As such, and depending upon the compressibility of the insulating members, the length and width may be somewhat less than, substantially greater than, or substantially equal to the matching dimensions of the container body. In other implementations, adhesive may be used to adhere some or all of the insulating members within the container body, such that the dimensions of the insulating members may differ more substantially from those of the container body.
As one illustrative example, where a friction fit is used, for top insulating member 26, the length LT and width WT may be selected based on the length LC and width WC of container body 12. Bottom insulating member 28, however, is sized to be inserted into container body 12 after side insulating member 30, so the length LB and width WB may be selected to be smaller than the LT and width WT of top insulating member 26 by about 2 x the thickness TS of side insulating member 30.
For side insulating member 30, the width WS is generally selected based on the height HC of container body 12, and in some implementations, may be smaller than height HC by a distance of about the thickness TT of top insulating member 26, such that when side insulating member 30 and top insulating member 26 are placed in container body 12, substantially all of the interior space of container body 12 is occupied by the insulating members. In other implementations, however, it may be desirable to select a width WS that is substantially less than the height HC to provide space for an uninsulated compartment within insulated container 10, e.g., if it is desirable to provide a compartment for items that do not need to be (or are desirably not) maintained at the same temperature as items within the insulated interior compartment.
In the illustrated implementation, the overall length LS of side insulating member 30 is selected to be similar to, but slightly less, than the perimeter of top insulating member 26, which may be considered to be substantially equal to 2 x (LT + WT). In particular, it may be desirable in some implementations to subtract the thickness TS of side insulating member 30 from the perimeter such that one side portion, e.g., side portion 38, is sized to account for an end of the opposite end side portion 32 to be in contact with the same side of container body 12. The lengths of the individual side portions 32, 34, 36, 38 are accordingly selected based on the length LC and width WC of container body 12, e.g., with the lengths L1 and L3 of side portions 32 and 36 selected based on the length LC of container body 12 and the lengths L2 and L4 of side portions 34 and 38 selected based on the width WC of container body 12, but with the length L4 of side portion 38 reduced relative to length L2 of side portion 34 by the thickness TS for the reasons discussed above.
Assembly of insulated container 10 is illustrated in
It should be noted that when side insulating member 30 is folded and inserted into container body 12, side portion 32 contacts side 16 of container body 12, side portion 34 contacts side 20 of container body 12, side portion 36 contacts side 14 of container body 12, and side portion 38 contacts side 18 of container body 12. Moreover, by virtue of the aforementioned dimensions of side portions 32 and 38, side edge surface 46 of side portion 32 also contacts side 18 of container body 12, while side edge surface 48 of side portion 38 contacts a portion of inwardly-facing surface 52 defined on side portion 32. Moreover, bottom edge surface 42 contacts bottom 22 of container body 12, while top edge surface 44 faces away from the bottom of the container body.
Next, as illustrated in
Next, prior to shipment, items may be placed into insulated interior compartment 54, and further, an ice pack, heat pack, or other system for controlling the temperature within interior compartment 54 may be placed within the interior compartment. Thereafter, as illustrated in
In addition, it will be appreciated that downwardly-facing surface 68 of bottom insulating member 28 and bottom edge surface 42 of side insulating member 30 cooperatively define a bottom of insulated interior compartment 54 and are both in contact with the bottom 22 of container body 12. Furthermore, it will be appreciated that bottom insulating member 28 may be friction fit within the interior space defined by side insulating member 30 in a manner in which edge surface portions 56, 58, 60, 62 are in contact with, and in some instances, pressing outwardly against, inwardly-facing surface 52 of side insulating member. Such an arrangement may be beneficial in some implementations as it may provide superior leak resistance to an alternate configuration where a bottom insulating member is sized similarly to a top insulating member such that it overlaps the entire bottom of the container body and the bottom edge surface of the side insulating member sits on top of the bottom insulating member. Moreover, as compared to the aforementioned alternate configuration, such an arrangement may provide additional structural support to the insulated container by pressing side portions 32, 34, 36, 38 of side insulating member 30 against sides 14, 16, 18, 20 of container body 12, and restricting movement of the individual side portions 32, 34, 36, 38 within container body 12.
Insulating members 26, 28, 30 may be constructed in a number of different manners consistent with the invention. As illustrated in
In some implementations, multi-material and/or multi-layer constructions may be used.
It will be appreciated that, while certain features may be discussed herein in connection with certain implementations and/or in connection with certain figures, unless expressly stated to the contrary, such features generally may be incorporated into any of the implementations discussed and illustrated herein.
Moreover, features that are disclosed as being combined in some implementations may generally be implemented separately in other implementations, and features that are disclosed as being implemented separately in some implementations may be combined in other implementations, so the fact that a particular feature is discussed in the context of one implementation but not another should not be construed as an admission that those two implementations are mutually exclusive of one another. Various additional modifications may be made to the illustrated implementations consistent with the invention. Therefore, the invention lies in the claims hereinafter appended.
