[0032] In the following description of the examples, reference is made to the accompanying drawings, which form a part of this disclosure and in which various examples in which aspects of the disclosure may be practiced are shown by way of illustration. It should be understood that other examples may be utilized and structural and functional modifications may be made without departing from the scope and spirit of the present disclosure. In addition, although the terms "top", "bottom", "front", "side", "rear", etc. may be used in this specification to describe various example features and elements of the examples, these terms are used herein for convenience, for example based on the example orientations shown in the figures or orientations during typical use. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of a structure to fall within the scope of the present disclosure.

[0033] Aspects of the present disclosure relate to a lid assembly 100 and an insulated container 200 . Figures 1 to 11 depicts a lid assembly 100, Figures 12 to 21 Insulated container 200 is depicted. Insulated container 100 may be used as a container or can for liquids, beverages, ice, food, etc. Figures 1 to 11In the example cap assembly 100 of the embodiment, the cap assembly 100 can be configured to be fastened to the container 200 so that the cap assembly 100 is not easily removed from the container 200 during use of the container 200. The example cap assembly 100 can be configured to be removably fastened to the container 200 via a series of grooves 120a, 120b, 120c, and 120d on the cap assembly 100, wherein the grooves 120a, 120b, 120c, and 120d are configured to align with protrusions 220a, 220b, 220c, and 220d located on the container 200. Thus, a user can align the grooves 120a, 120b, 120c, and 120d of the cap assembly 200 with the protrusions 220a, 220b, 220c, and 220d on the container 200 and twist the cap assembly 200 to lock the cap assembly 200 in place on the container 200.

[0034] Turning specifically to the cap assembly 100, in one example, as Figure 1 、 Figure 2 and Figure 7 As shown, the lid assembly 100 can include a lid assembly pour spout 102 having a shape and size corresponding to the container pour spout 202 discussed below. The lid assembly 100 can also include a top surface 104 positioned at a certain angle toward the lid assembly pour spout 102 to facilitate pouring the contents from the insulated container 200, such as Figure 9 The top surface 104 may include a top surface channel 106 for receiving a slider 108, as shown. Figure 1 The top surface channel 106 may also include an opening 110 adjacent to the lid assembly pouring spout 102 for dispensing the contents of the container 200, such as Figure 2 As shown. The channel 106 may also include a pair of vent holes 125 to vent air within the container 200 when liquid is dispensed through the opening 110. In addition, a vent hole 127 may be provided on the top surface 104 of the lid assembly 100 opposite the opening 110. The lid assembly 100 may also include a rim 112 configured to extend above the rim 212 of the container 200 when assembled to the container 200. The slider 108 is configured to move from an open position, in which the user can access the contents of the container, for example by pouring, to a closed position, in which the slider 108 covers the opening to prevent the contents of the container from spilling.

[0035] like Figures 2 to 6As shown, the lid assembly 100 can also include a skirt 114 extending axially from the rim 102. The skirt 114 can include a radially extending channel 128 around a top portion of the skirt 114, and the gasket 130 can be positioned in the radially extending channel 128. Additionally, in this example, the skirt 114 can include a plurality of skirt grooves 120a, 120b, 120c, and 120d that correspond to the plurality of container protrusions 220a, 220b, 220c, and 220d on the insulated container 200. In this example, as discussed herein, the lid assembly 110 is configured to be locked in place on the container when in the locked position by engaging the plurality of skirt grooves 120a, 120b, 120c, and 120d with the container protrusions 220a, 220b, 220c, and 220d. The lid assembly 100 may include a gripping element 126 that a user uses to rotate the lid assembly relative to the insulated container 200 to secure the lid assembly 100 to the insulated container 200 or to remove the lid assembly 100 from the insulated container 200. For example, Figure 2 As shown, the skirt 114 may include a series of optional molded channels or notches 182A, 182B, 182C. These optional channels or notches may be implemented to restrict the flow of resin used to form the cap to provide better molding performance.

[0036] In other examples, it is contemplated that the skirt 114 or other portion of the lid assembly 100 may include a plurality of protrusions, and the container may include a plurality of recesses that correspond to and receive the protrusions on the skirt 114 or other portion of the lid assembly 100. Furthermore, while four recesses and protrusions are used in this example, it is contemplated that more or fewer recesses and protrusions may be used without departing from the present disclosure.

[0037] like Figures 1 to 6 As shown, a plurality of skirt grooves 120a, 120b, 120c, 120d may be positioned below the gasket 130. Furthermore, the plurality of skirt grooves 120a, 120b, 120c, 120d extend in radial and axial directions. Figure 3 As shown, the plurality of skirt grooves may each have a first straight portion 122 extending in both radial and axial directions on the lid assembly skirt 114 and a second straight portion 124 extending only in the radial direction. In one example, when the lid assembly 100 is assembled to the insulated container 200, the first straight portion 122 may be oriented at approximately 45 degrees relative to the port center axis 236, as shown in FIG. Figure 17As shown. In this example, the first straight portion 122 can be longer than the second straight portion 124. Moreover, when assembled, the second straight portion 124 can be substantially parallel to the rim 212 of the insulated container 200. In this example, the first straight portion and the second straight portion can extend a total of approximately 10 degrees to 180 degrees in the radial direction, and in one example, the first straight portion and the second straight portion can extend a total of approximately 10 degrees to 30 degrees in the radial direction. Therefore, in this example, the user can rotate the lid assembly 200 between eight turns and half a turn to lock the lid assembly to the container 100, thereby securing the lid assembly 100 to the container 200. In this example, the plurality of grooves 120a, 120b, 120c and 120d can extend a certain depth in the side wall forming the skirt 114, and the depth corresponds to the depth of the plurality of protrusions 220a, 220b, 220c and 220d in the container. In other examples, the plurality of grooves 120 a , 120 b , 120 c , and 120 d may extend completely through the sidewalls forming the skirt 114 .

[0038] In this example, as shown in the bottom view of the cover assembly 100 Figure 8 As shown, the plurality of skirt grooves 120a, 120b, 120c, 120d are positioned asymmetrically about the cap assembly around the circumference of the cap assembly 100. As such, the plurality of skirt grooves 120a, 120b, 120c, and 120d can be positioned asymmetrically about the cap in a radial direction, meaning that each of the plurality of skirt grooves 120a, 120b, 120c, and 120d can be positioned at a different radial dimension relative to one another or at a different angle relative to one another. Furthermore, in this example, as Figures 1 to 6 As shown, the plurality of skirt grooves 120a, 120b, 120c, 120d can be positioned at the same distance or depth in the axial direction relative to the rim 102. In this example, due to the asymmetric plurality of insulating container protrusions 220a, 220b, 220c, 220d and the asymmetric plurality of skirt grooves 120a, 120b, 120c, and 120d, the lid assembly 100 can be configured to be placed on the container 200 in a single orientation. In addition, due to the corresponding shapes of the lid assembly mouth 102 and the container mouth 202, the lid assembly 100 can be configured to be placed on the container 200 in a single orientation.

[0039] In this example, see FIG. 1 which shows a bottom view of the lid assembly 100. Figure 8 , the lid assembly mouth 102 can define a mouth central axis 136. A first skirt groove 120a among the plurality of skirt grooves can be positioned at a first angle α relative to the lid assembly mouth central axis 136. Additionally, a second groove or protrusion 120b among the plurality of grooves or protrusions of the container can be positioned at a second angle β relative to the lid assembly mouth central axis 136. The first angle α can be greater than the second angle β.

[0040] In this example, a third skirt groove 120c among the plurality of skirt grooves may be positioned at a third angle γ relative to the port center axis 136. Furthermore, a fourth skirt groove 120d among the plurality of skirt grooves may be positioned at a fourth angle δ relative to the port center axis 136. In this example, the fourth angle δ is less than the third angle γ. Furthermore, the fourth angle δ is less than the first angle α. In one specific example, the first angle α may be approximately 44 degrees, the second angle β may be approximately 20 degrees, the third angle γ may be approximately 45 degrees, and the fourth angle δ may be approximately 38 degrees. Thus, the plurality of skirt grooves 120a, 120b, 120c, and 120d may each be positioned at a different angle relative to an adjacent groove among the plurality of skirt grooves 120a, 120b, 120c, and 120d, and each of the first angle α, the second angle β, the third angle γ, and the fourth angle δ may be an acute angle less than 90 degrees.

[0041] Furthermore, the sum of the first angle α and the second angle β may be approximately 64 degrees to form an acute angle between the first skirt groove 120a and the second skirt groove 120b among the plurality of skirt grooves. Furthermore, the sum of the third angle γ and the fourth angle δ may be approximately 83 degrees to form an acute angle between the third skirt groove 120c and the fourth skirt groove 120d among the plurality of skirt grooves.

[0042] In addition, a fifth angle θ may be formed between the second skirt groove 120b and the third skirt groove 120c among the plurality of skirt grooves, and a sixth angle λ may be formed between the fourth container protrusion 120d and the first container protrusion 120a.

[0043] The fifth angle θ may be approximately 115 degrees, and the sixth angle λ may be approximately 98 degrees. Thus, both the fifth angle θ and the sixth angle λ may be obtuse angles greater than 90 degrees. Thus, the fifth angle θ between the second skirt groove 120b of the plurality of skirt grooves and the third skirt groove 120c of the plurality of skirt grooves may be an obtuse angle. Furthermore, the sixth angle λ between the first skirt groove 120a of the plurality of skirt grooves and the fourth skirt groove 120d of the plurality of skirt grooves may be an obtuse angle.

[0044] In an alternative example, it is contemplated that multiple skirt grooves 120a, 120b, 120c, 120d can be replaced by protrusions. In another example, multiple skirt grooves 120a, 120b, 120c, 120d can be a combination of grooves and protrusions. In addition, it is contemplated that multiple skirt grooves 120a, 120b, 120c, and 120d can be positioned symmetrically in the radial direction. In addition, in other examples, it is contemplated that multiple skirt grooves 120a, 120b, 120c, and 120d can be positioned at different distances or depths relative to the rim 112 in the axial direction, and corresponding multiple container protrusions 220a, 220b, 220c, and 220d are correspondingly positioned to align with the multiple skirt protrusions 120a, 120b, 120c, and 120d when the lid assembly 100 is positioned in the locked position. It is also contemplated that the cap assembly may include one or more biasing members or springs for positioning, further securing or locking the cap assembly skirt recesses 120a, 120b, 120c, 120d in place on the container protrusions 220a, 220b, 220c and 220d.

[0045] See also Figure 5 、 Figure 6 , the gasket 130 can be positioned directly below the cover 112 and can have a single blade 131. In other examples, the gasket can be a face seal gasket, a corner seal gasket, or have a C-shaped cross-section. In some examples, the cover assembly installation torque can be 1 ft*lb to 8 ft*lb or between 1 ft*lb and 8 ft*lb, and in one specific example, the cover assembly installation torque can be 2 ft*lb to 3 ft*lb or between 2 ft*lb and 3 ft*lb, and particularly about 2.6 ft*lb. Also in some examples, the cover unloading torque can be between 0.5 ft*lb to 4.5 ft*lb, and in one specific example, the unloading torque can be 0.5 ft*lb to 2.0 ft*lb, and particularly about 1.5 ft*lb.

[0046] In one example, the lid assembly 100 can include a movable slider 108 that can include a tab or handle 109 for a user to grasp to move the slider 108 to an open position or a closed position. In one example, the slider 108 of the lid assembly 100 can be a magnetic slider. In some examples, the slider 108 can be configured to perform one or more of the following operations: (1) slide between a closed position and an open position, in which the slider covers the opening to help prevent the contents of the container from spilling, and an open position in which the slider 108 opens the opening 110 so that the contents of the container can be consumed, (2) lock in place between the closed position and the open position, (3) remain secured to the lid assembly 200 during movement between the closed position and the open position, or (4) be removable from the lid assembly 100 so that the lid assembly 100 and the slider 108 can be cleaned. The slider 108 and cover assembly 100 may be similar to the slider and cover assembly described in US Patent Application No. 14 / 971,779, filed December 16, 2015 (now US Patent No. 10,232,992), which is incorporated herein by reference in its entirety.

[0047] like Figure 9 and Figure 10 As shown, the lid assembly 100 may be provided with two magnets, which may be disc-shaped magnets 170A and 170B. The slider 108 may also be provided with a disc-shaped magnet, not shown. The disc-shaped magnet in the slider 108 may be a first clamping and positioning magnet, and the disc-shaped magnets 170A and 170B may be the second and third clamping and positioning magnets 170A and 170B in the lid assembly 100. In this example, the magnets may hold the slider 108 on the lid assembly 100 and maintain the slider 108 in an open position or a closed position during use. For example, the first clamping and positioning magnet in the slider interacts with the second clamping and positioning magnet 170A to maintain the lid assembly 100 in the open position; and the first clamping and positioning magnet in the slider interacts with the third clamping and positioning magnet 170B to maintain the lid assembly 100 in the closed position.

[0048] Figure 9 、 Figure 10 and Figure 11 A cross-sectional view of the lid assembly 100 is shown without the slider 108. As shown in FIG30 , a magnet shield 172 can be positioned on top of the lid assembly 100. The magnet shield 172 can include a second clamping and positioning magnet 170A and a third clamping and positioning magnet 170B, wherein the second clamping and positioning magnet 170A and the third clamping and positioning magnet 170B can be enclosed within the magnet shield 172. In one example, the magnet shield 170 can be molded into the lid assembly 100 as an integral component.

[0049] Likewise Figure 7As shown, lid assembly 110 may also include a small bump 174 within channel 106. Bump 174 may be located on the rear wall of channel 106. Bump 174 provides a stop for slider 108, causing slider 108 to engage with bump 174 when in the fully open position. This creates a gap between slider 108 and the rear wall of channel 106, which helps prevent any liquid in channel 106 from shifting within channel 106. This, in turn, helps prevent the slider from moving to the open position and causing liquid in channel 106 to splash onto the user, thereby providing a better user experience. Furthermore, slider 108 may have a tapered end, which also creates a gap between slider 108 and the channel, thereby reducing the amount of splashing from any contents in channel 106 of lid assembly 100. This can be particularly helpful near the lid's opening, where, due to the angle of channel 106, liquid tends to travel down the slope of channel 106 and collect near opening 110 of lid assembly 100. In this way, when the user closes the lid assembly 100 with the slider 108 , splashing of the contents near the opening of the lid assembly 100 is reduced.

[0050] It is also contemplated that the slider does not include a magnet and relies on one or more detents, protrusions, channels to maintain the slider in an open or closed position, such as those described in U.S. patent application Ser. No. 14 / 971,779, filed Dec. 16, 2015 (now U.S. Pat. No. 10,232,992), which is incorporated herein by reference in its entirety.

[0051] Now turn to the insulated container 200, as Figures 12 to 21 As shown, the insulated container 200 may include an outer shell 230 having an outer sidewall shell 230A and an outer bottom wall shell 230B. The insulated container 200 may also include an inner shell 232 having an inner sidewall 232A and an inner bottom wall 232B. The outer shell 230 may be connected to the inner shell 232 to form an insulated double-wall structure, wherein a sealed vacuum cavity is provided between the outer shell 230 and the inner shell 232. The insulated container 200 may have a top opening 234 located at the top of the inner sidewall 232A, leading to a storage cavity 240 formed by the inner sidewall 232A and the inner bottom wall 232B. The top opening 234 may also include a container pouring spout 202. Although the example shown has a generally cylindrical shape, the shape of the container 100 may be any shape, such as a rectangular cube, or other desired three-dimensional shape that can hold fluids, beverages, or other food products.

[0052] In this example, as described above, the thermally insulated container 200 may include a plurality of container protrusions 220a, 220b, 220c, 220d, such as Figure 15 、 Figure 17 and Figure 18As shown. And in this example, the number of the plurality of container protrusions 220a, 220b, 220c, 220d can be four. The plurality of container protrusions 220a, 220b, 220c and 220d can be positioned radially around the container. Figure 12 、 Figure 15 and Figure 17 As shown, a plurality of protrusions may be positioned on the inner sidewall 232a of the insulated container 200 .

[0053] In one example, the plurality of insulated container protrusions 220a, 220b, 220c, 220d of the insulated container 200 can be oriented asymmetrically around the circumference of the container 200. Furthermore, in this example, the plurality of insulated container protrusions 220a, 220b, 220c, 220d can be positioned asymmetrically in a radial direction about the lid, meaning that each of the plurality of insulated container protrusions 220a, 220b, 220c, 220d can be positioned at a different radial dimension relative to one another or at a different angle relative to one another. Also in this example, the plurality of insulated container protrusions 220a, 220b, 220c, 220d can be positioned at the same distance or depth relative to the rim 202 of the insulated container in an axial direction.

[0054] In this example, see FIG. 1 which shows a top view of an insulated container. Figure 17 Insulated container mouth 202 can define a mouth central axis 236, and handle 238 can define a handle central axis, which can be the same as mouth central axis 236. A first insulated container protrusion 220a among the plurality of insulated container protrusions can be positioned at a first angle α relative to container mouth central axis 236 and handle central axis 236. Furthermore, a second insulated container protrusion among the plurality of insulated container protrusions can be positioned at a second angle β relative to the axes. The first angle α can be greater than the second angle β.

[0055] In this example, a third protrusion 220c among the plurality of protrusions of the insulated container can be positioned at a third angle γ relative to the mouth center axis 236 and the handle center axis 236. In addition, a fourth container groove 220c among the plurality of container grooves can be positioned at a fourth angle δ relative to the handle axis. In this example, the fourth angle δ is smaller than the third angle γ. In addition, the fourth angle δ is smaller than the first angle. In a specific example, the first angle α can be approximately 44 degrees, the second angle β can be approximately 20 degrees, the third angle γ can be approximately 45 degrees, and the fourth angle δ can be approximately 38 degrees. Therefore, the plurality of container protrusions 220a, 220b, 220c, 220d can be positioned at different angles relative to adjacent protrusions among the plurality of container protrusions 220a, 220b, 220c, 220d, respectively, and each of the first angle α, the second angle β, the third angle γ, and the fourth angle δ can be an acute angle.

[0056] Furthermore, the sum of the first angle α and the second angle β may be approximately 64 degrees to form an acute angle between the first protrusion 220a and the second protrusion 220b among the plurality of protrusions. In addition, the sum of the third angle γ and the fourth angle δ may be approximately 83 degrees to form an acute angle between the third protrusion 220c and the fourth protrusion 220d among the plurality of protrusions.

[0057] In addition, a fifth angle θ may be formed between the second container protrusion 120B and the third container protrusion 120c, and a sixth angle λ may be formed between the fourth container protrusion 120d and the first container protrusion 120a. The fifth angle θ may be approximately 115 degrees, and the sixth angle λ may be approximately 98 degrees. Thus, both the fifth angle θ and the sixth angle λ may be obtuse angles greater than 90 degrees. Accordingly, the fifth angle θ between the second protrusion 220b and the third protrusion 220c of the plurality of protrusions may be an obtuse angle. And the sixth angle λ between the first protrusion 220a and the fourth protrusion 220d may be an obtuse angle. The first angle α, second angle β, third angle γ, fourth angle δ, fifth angle θ, and sixth angle λ relative to the container may correspond to the first angle α, second angle β, third angle γ, fourth angle δ, fifth angle θ, and sixth angle λ discussed above with respect to the lid assembly.

[0058] like Figure 17 The enlarged image (i.e. Figure 18 ), each of the plurality of protrusions 220a, 220b, 220c, 220d extends from the inner wall of the thermally insulated container. Figure 18 The enlarged cross section Figure 19 , the plurality of container protrusions 220a, 220b, 220c, and 220d may each have an elliptical shape. In this example, the plurality of container protrusions each have a width-to-length ratio greater than 1. In a specific example, the height of the protrusions 220a, 220b, 220c, and 220d may be approximately 3 mm, and the width of the protrusions 220a, 220b, 220c, and 220d may be approximately 4 mm.

[0059] In an alternative example similar to lid assembly 200, it is contemplated that the plurality of insulated container protrusions 220a, 220b, 220c, 220d may be replaced with grooves similar to the lid assembly skirt grooves 120a, 120b, 120c, and 120d discussed herein. In another example, the plurality of insulated container protrusions 220a, 220b, 220c, and 220d may also be a combination of grooves and protrusions. Furthermore, it is contemplated that the plurality of insulated container protrusions 220a, 220b, 220c, and 220d may be positioned symmetrically in the radial direction. Furthermore, in other examples, it is contemplated that a plurality of insulated container protrusions 220a, 220b, 220c, 220d can be positioned at different distances or depths relative to the insulated container rim 212 in the axial direction, and that a corresponding plurality of skirt grooves 120a, 120b, 120c, and 120d are correspondingly positioned to align with the insulated container protrusions 220a, 220b, 220c, and 220d when the lid assembly 100 is positioned in the locked position.

[0060] Due to the asymmetric plurality of insulated container protrusions 220a, 220b, 220c, 220d and the asymmetric plurality of skirt grooves 120a, 120b, 120c, 120d, the lid assembly can be configured to be placed on the container in a single orientation. The engagement of the plurality of skirt grooves 120a, 120b, 120c, 120d with the insulated container protrusions 220a, 220b, 220c, 220d can generate a first force, and the engagement of the gasket with the inner wall of the insulated container can generate a second force, wherein the first force and the second force are configured to help retain the lid assembly on the container assembly. Furthermore, the slider 108 can be retained on the lid assembly 100 by the first force, and the lid assembly 100 can be retained on the container 200 by the second force, and the second force can be greater than the first force. When the cap assembly 100 is in the locked position, the plurality of container protrusions 220a, 220b, 220c engage the second straight portions 124 of the plurality of skirt grooves 120a, 120b, 120c, and 120d in the locked position.

[0061] In alternative configurations, it is also contemplated that the lid assembly 100 may be secured to the insulated container assembly 200 using one or more of threads, bayonet connections, hinges, or collars. In another example, a suction button or mechanism that draws air from the container or expands a gasket may be used to form a seal between the lid assembly 100 and the container assembly 200. It is also contemplated that the lid assembly 100 may be retained on the container assembly 200 solely by the friction generated between the gasket 131 and the container assembly 200. In this example, the lid assembly 100 may include an outwardly extending tab extending from the rim to provide a user with leverage to remove the lid assembly from the container.

[0062] like Figure 21As shown, the container assembly 200 may include a foot member 290 to provide a non-slip surface for supporting the container 200. Example foot members are described in U.S. Application No. 17 / 868,471, filed on July 19, 2022, and U.S. Application No. 16 / 146,692, filed on September 18, 2018 (now U.S. Patent No. 10,729,261), each of which is incorporated herein by reference in its entirety. The foot member 290 may be attached to the outer bottom wall 230B. Figure 15 and Figure 16 As shown, the outer bottom wall 230B may include a lower cavity 231. The lower cavity 231 may include an inner cavity wall 231A, an outer cavity wall 231B, and a bottom cavity wall 231C. The lower cavity 231 may be annular, such that the inner cavity wall 231A and the outer cavity wall 231B respectively form a continuous loop separated from each other.

[0063] While the illustrated example includes an annular lower chamber 130, the lower chamber may also have other shapes, such as square, circular, oval, or other geometric shapes. In other examples, the lower chamber 231 may include multiple chambers. Additionally, in examples with multiple lower chambers, each lower chamber may include a separate support member, or a support member partially housed within each lower chamber.

[0064] In one example, if Figure 16A As shown, a foot stand 292 can be located in the annular lower cavity 231. The foot stand 292 can be connected to the bottom cavity wall 231C and can include one or more hook members 292A, 292B located on the foot stand 292 that engage and secure the elastomeric foot member 290. The plurality of hook members 292 form a snap-fit ​​connection with the elastomeric foot member 290. The foot member 290 can be annular and form a non-slip surface to support the container 200. In this example, the foot member 290 can be shaped to be compatible or mating with the foot stand 292. For example, the bottom of the foot member 290 can be a flat surface 294. The other side of the foot member 290 can include two curved ends 290A, 290B and a double ridge 296 located in the middle of the foot and separated by a gap 297. Accordingly, as described above, the foot stand 290 may include a plurality of hook members 292A, 292B or two curved ends that cooperate with the curved ends 290A, 290B of the foot stand 290. In addition, the foot stand 292 may include a central gap 297 located between the two curved ends of the foot stand 292. Figure 16A As shown, the dual ridges 296 of the foot member 290 are configured to mate with the central gap 297 of the foot stand 292. In this example, the foot member 290 can be pressed onto the stand 292 and snap-fit ​​with the container 200, and can be designed not to be removed by the user.

[0065] In addition, a depression, recess, or opening 276 for forming a vacuum can be located on the bottom cavity wall 231C. The opening 276 can be a circular hole and can be positioned on the axis of the handle and the mouth. In the illustrated example, there is only one opening, but multiple openings are also contemplated. As described below, the opening 276 can facilitate venting gas from the cavity formed between the outer shell 230 and the inner shell 232. In addition, the opening 276 can be aligned with a corresponding protrusion (not shown) disposed on the bottom surface of the stand 290.

[0066] As described above, an opening, indentation, or dimple structure 276 is used during the vacuum forming process. However, the opening, indentation, or dimple structure 276 can be included anywhere on the outer shell 230 or the inner shell 232. This dimple structure and its formation process are disclosed and described in U.S. application No. 16 / 146,692 filed on September 18, 2018 (now U.S. Patent No. 10,729,261), U.S. application No. 62 / 237,419 filed on October 5, 2015, U.S. application No. 62 / 255,886 filed on November 16, 2015, and U.S. application No. 15 / 285,268 (now U.S. Patent No. 10,390,659), all of which are incorporated herein by reference in their entirety. In one example, the shape of the indentation or dimple 276 can be similar to a dome. However, other suitable shapes can also be envisioned to accommodate the resin material during the manufacturing process. The example container assembly 200 may be provided with one or more vacuum chambers, such as Figure 15 The inner cavity 233 shown in the figure is formed to reduce heat transfer by conduction, convection and / or radiation. To achieve a vacuum between the outer and inner bodies of the bowl, air can be removed from the container by heating the container in a vacuum and removing the air between the outer shell 230 and the inner shell 232 through openings in the indentations or recesses 276 in the outer shell 230 and / or the inner shell 232.

[0067] The indentation or recess 276 can provide a conduit to the interior cavity during the forming process. Specifically, the container 200 can be oriented upside down within the vacuum forming chamber, and during the vacuum forming process, a pill-shaped amount of resin can be placed into the indentation or recess at the bottom of the container. In some examples, the resin can have a diameter of approximately 3 mm to 5 mm, and the opening in the indentation or recess can be approximately 1 mm in size. Thus, when the container 200 is heated, the resin becomes viscous, preventing it from flowing or dripping through the opening into the interior cavity 233 of the container 200. However, it is breathable, allowing air to escape from the interior cavity 233 or other internal volumes of the container 200. Once the resin cools and solidifies, it covers the opening of the indentation or recess and seals the interior cavity 233 or other internal volumes of the container 200, creating a vacuum within the container 200. Any suitable resin is contemplated for use in forming the vacuum within the container 200. In some examples, the resin material can be synthetic, such as epoxy, or can be plant-based. In this example, after vacuuming, the dimple or indentation 276 can be covered by the foot member 290. However, it is also conceivable that the resin can be polished so that the dimple or indentation is not noticeable or easily noticed by the user. In other examples, the dimple or indentation can be covered by a cap and polished in the same manner so that the cap and the dimple or indentation are not noticeable or easily noticed by the user.

[0068] In addition, various other techniques can also be used to cover or seal the pit, which can include applying resin, powder coating the pit, adhering metal or paper to the opening, or adding rubber or plastic parts to cover the opening, or including rubber or plastic parts at the bottom. In other examples, the pit or dent can be covered or sealed with a disc or end cap (not shown). Welding the disc to the bottom of the container 200 or welding the end cap to the bottom of the shell 230 provides a more permanent structure that can be reused and cleaned without destroying the structural integrity of the container 200. Covering the dent with a disc can obtain a more compact container 200 because the end cap can increase the total height of the container. Because less material is needed, this can help save container manufacturing costs. In addition, the container will be able to store more liquid with a smaller container volume and length. Alternatively, the container 200 can be configured with a pit or dent (not shown) on the inner shell 232 to promote the vacuumization process as described herein.

[0069] Other alternative methods of insulating container 200 are also contemplated. For example, inner cavity 233 can be filled with various insulating materials exhibiting low thermal conductivity, such as foam. Thus, in some examples, inner cavity 233 can be filled with air to form air pockets for insulation, or filled with a bulk material, such as a polymer material or polymer foam. In one specific example, inner cavity 233 can be filled with polystyrene. However, inner cavity 233 can be filled with additional or alternative insulating materials without departing from the scope of this disclosure. In some examples, inner cavity 233 is filled with insulating material by injecting the insulating material into inner cavity 233 through recesses, indentations, or other conduits. In other examples, insulating material is added to inner cavity 233 prior to coupling inner shell 232 to outer shell 230. In other examples, inner cavity 233 can be configured to be partially or fully filled with additional insulating material. For example, inner cavity 233 can be configured to be, or can be, at least partially filled with, an alternative polymer foam, such as polystyrene foam, polyvinyl chloride foam, or polyimide foam, among others.

[0070] To form the insulated container, the outer shell 230 and the inner shell 232 can be formed as two single pieces. The outer shell 230 and the inner shell 232 can have a substantially constant wall thickness. The outer shell 230 and the inner shell 232 can be constructed using one or more sheet metal deep drawing and / or stamping processes, and in one example are constructed using stainless steel sheets. However, it is readily understood that the insulated container 200 can also be constructed using one or more additional or alternative metals and / or alloys, one or more fiber reinforced materials, one or more polymers, or one or more ceramics, or a combination thereof, without departing from the scope of these disclosures. Therefore, the wall thickness (i.e., the thickness of the available sheet metal) of one or both of the outer shell 230 and the inner shell 232 can range from 0.2 mm to 4 mm or between 0.2 mm and 4 mm, or approximately 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, etc.

[0071] In one specific example, the inner shell 232 can be fastened to the outer shell 230 by a welding operation, using a robotic arm and a camera system in combination with fixed electrodes, etc., to ensure that the inner shell 230 is connected along the entire upper edge of the outer shell 230 and the inner shell 232. These coupling processes can integrally combine the outer shell 230 and the inner shell 232, and can include one or more brazing or welding processes (including, among others, shielded metal arc, gas tungsten arc, gas metal arc, flux-cored arc, submerged arc, electroslag, ultrasonic, cold pressing, electromagnetic pulse, laser beam, or friction welding processes). In another example, the outer shell 230 can be integrally joined to the inner shell 232 by one or more adhesives, sheet metal crimping joints, or one or more fastener elements (e.g., one or more screws, rivets, pins, bolts, or staples, etc.).

[0072] Once the shells 230 and 232 are integrally joined, a significant amount of gas / air can be evacuated from the cavity formed between the inner shell 232 and the outer shell 230, thereby forming a sealed vacuum cavity 233 between the two shells 230 and 232. To achieve a vacuum between the walls of the container 200 (e.g., between the outer sidewall 230 and the inner sidewall 232, and between the outer bottom wall 230B and the inner bottom wall 232B), at least a portion of the air between the two shells 230 and 232 can be removed by positioning the container 200 within a larger chamber (not shown) and removing at least a portion of the air from the cavity 233 between the shells 230 and 232 by pulling a vacuum within the larger chamber (not shown) (e.g., reducing the internal pressure of the larger chamber to a level lower than the internal pressure within the vacuum cavity 233). It should be understood that any technique and / or process can be utilized to reduce the pressure within the larger chamber (not depicted), including vacuum pumping, etc. In this way, some of the air within the vacuum chamber 233 can escape through a depression or indentation 276 in the bottom chamber wall 231C of the lower chamber 231 on the outer bottom wall 230B. Similarly, it is also contemplated that a plurality of depressions, indentations, or openings may be provided on the outer bottom wall 230B. In one example, the openings 276 may be circular holes. Alternatively, the openings 276 may be located in the bottom chamber wall 231C and further aligned with holes (not shown) disposed in the foot member, thereby allowing the vacuum to be applied after the foot member 290 is applied to the housing 230.

[0073] In some embodiments, the pressure within the vacuum chamber 233 of the insulated container 200 can be measured to be less than 15 μTorr. In other examples, the vacuum can be measured to be less than 10 μTorr, less than 50 μTorr, less than 100 μTorr, less than 200 μTorr, less than 400 μTorr, less than 500 μTorr, less than 1000 μTorr, less than 10 mTorr, less than 100 mTorr, or less than 1 Torr, among others.

[0074] To seal the vacuum within vacuum chamber 120, during the vacuum forming process, a pill-shaped pellet of resin may be placed in the depression, indentation, or opening 276. In some examples, the vacuum forming chamber may be heated to a temperature at which the resin becomes viscous. In one example, the viscosity of the resin may be such that the resin does not flow or drip into the container through the opening, but is breathable, allowing air to escape the interior volume of vacuum chamber 233. In one embodiment, the vacuum forming process may heat the insulated container 200 to a temperature of approximately 550°C. In other embodiments, the insulated container may be heated to approximately 200°C, 250°C, 300°C, 350°C, 400°C, 450°C, 500°C, or 600°C, etc., during the vacuum forming process. After a period of heating, the insulated container 200 may be passively or actively cooled to room temperature. Thus, once the resin cools and solidifies, it covers the depression, indentation, or opening 276 and seals the interior volume of container 200, thereby forming vacuum chamber 233 between outer shell 230 and inner shell 232.

[0075] Finally, the foot member 290 can be mounted to a foot stand (not shown). The foot member 290 can be fastened to a hook member (not shown) of the foot stand (not shown) by a press fit or a friction fit. The foot member 290 can be formed of an elastomeric material to help increase friction and help prevent the container 200 from sliding when placed on a flat surface.
