The entire contents of the above applications are expressly incorporated herein by reference for any and all non-limiting purposes. Background Technology

[0003] Various types of containers are frequently used to store food or other items. In some cases, maintaining the temperature of the contents stored in the container may be advantageous. Therefore, insulated containers can be used. However, some conventional insulated containers are often not very durable and lack proper means of securing the lid in the closed position. For example, some conventional insulated containers have lids that may be lost or damaged, handles that may protrude from the base of the container, and / or ineffective latches for securing the lid. In these examples, the lid, handle, and / or latch may be prone to breakage, which in some cases may render the insulated container virtually useless. Summary of the Invention

[0004] The present invention is provided to present, in a simplified form, the selection of concepts further described below in the detailed description. The summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to limit the scope of the claimed subject matter.

In some examples, an insulated container can include a base, a lid hingedly attached to the base, and a handle assembly attached to the base. The base can include a sidewall structure, a bottom portion connected to the sidewall structure, an opening formed at an end of the sidewall structure, and at least one latching device configured to secure the lid when the lid is in a closed position. The sidewall structure can have a front sidewall, a back sidewall opposite the front sidewall, and two lateral sidewalls between the front sidewall and the back sidewall. The bottom portion can be connected to a first end of each sidewall of the sidewall structure, the bottom portion configured to support the insulated container on a surface. The opening can be formed at a second end of each sidewall of the sidewall structure opposite the first end of each sidewall of the sidewall structure. The opening can be configured to allow access to an interior space of the insulated container formed by the sidewall structure and the bottom portion. A gasket can be configured to provide a water-tight seal when the lid is in a closed and secured position. The handle assembly can be attached to the back sidewall. The handle assembly can include a telescoping three-stage arm configuration defined by a first stage with the handle assembly in a stowed configuration, a second stage with the handle assembly in a partially extended configuration, and a third stage with the handle assembly in a fully extended configuration. The handle assembly can include an upper arm, a middle arm, and a lower arm. The upper arm can be nested inside and slidable within the middle arm, and the middle arm can be nested inside and slidable within the lower arm, creating the telescoping three-stage arm configuration.

[0006] In other examples, the handle assembly can be attached to the rear side wall with one or more brackets. The one or more brackets can be U-shaped brackets that fit around the exterior of the lower arm against the rear side wall. The handle assembly can also include one or more locking mechanisms for locking the handle assembly in the stowed configuration and the fully extended configuration, the one or more locking mechanisms having an upper locking mechanism and a lower locking mechanism, the upper locking mechanism being between the upper arm and the middle arm, the lower locking mechanism being between the middle arm and the lower arm. The handle assembly can also include a release button located on the handle. The release button can be connected to and actuate the one or more locking mechanisms to lock and release the handle assembly between the stowed configuration and the fully extended configuration. The handle assembly can include an extended arm overlap distance defined as the overlap distance between the nested arms when the upper arm, the middle arm, and the lower arm are in the fully extended configuration. The extended arm overlap distance can be about 70 mm. The handle assembly can include a handle having one or more handle bumpers including a raised portion extending circumferentially around the handle. The insulated container can also include a corner lock bracket including a container bracket attached to the base, a lid bracket attached to the lid, and a lock. The container bracket can include a first lock hole and the lid bracket can include a second lock hole. The first lock hole and the second lock hole can mate together when the lid is in the closed and secured position, thereby allowing the lock to be inserted into the first lock hole and the second lock hole. Further, the at least one latching device can also include a latching upper portion, wherein the latching upper portion is pivotally attached to the lid, and a latching lower portion, wherein the latching lower portion is pivotally attached to the latching upper portion. The latching lower portion can also include an engagement tab configured to engage a retainer.

The stop 113 is configured to engage at least one or more stops 109c or protrusions (not shown) when the handle pivot 109 engages the insert 109b. The construction and geometry of the insert 109b and the handle pivot 109 prevent the carrying strap or handle 107 from rotating below the insulated container 100.

[0056] The base portion 102 also includes a second end portion 110, which defines an opening 112 (in FIG. 5A As shown in the diagram, opening 112 can be used to access the interior space of the insulated container. When the insulated container is in use (e.g., when the insulated container is in a closed configuration), opening 112 can be covered by cover 104. Base portion 102 may also include a plurality of side portions 114 attached to a bottom surface, the plurality of side portions 114 defining spaces for receiving contents within the insulated container 100. The side portions 114 may be arranged such that the side portions 114 extend generally perpendicularly from bottom surface 108.

[0057] In some examples, one or more side pocket handles 190 may be arranged in one or more side portions 114 (or other areas of the base portion 102). The side pocket handles may be integrally formed with the base portion 102 and are typically undercuts or slits formed in the side portions 114 of the base 102. In some examples, such as in FIG. 1A and FIG. 1B As shown, the undercut or cutout forming the side pocket handle may include a recess that extends substantially all or most of the side portion 114. This can provide an easy-to-manufacture base 102 with a one-piece handle 190. In some examples, the side pocket handle 190 may be flush with the outer surface of the base 102 to reduce the risk of breakage.

[0058] As discussed above, the insulated container 100 can be configured to contain, store, carry, or otherwise carry a certain volume of contents or possibly liquids. In some examples, the insulated container 100 can be configured to store contents between twenty-two (22) quarts and twenty-eight (28) quarts. In some examples, the insulated container can be configured to store approximately twenty-four (24) quarts of contents. In other examples, the insulated container can be configured to store at least twenty-two (22) quarts of contents, or the insulated container can be configured to store at least twenty-eight (28) quarts of contents, etc. In yet another example, the insulated container can be configured to store approximately sixteen (16) quarts of contents, twenty-four (24) quarts of contents, thirty-six (36) to thirty-eight (38) quarts of contents, or forty-eight (48) to fifty-eight (58) quarts of contents. In still another example, the insulated container 100 can be configured to store contents between approximately fourteen (14) quarts and approximately forty-five to twenty-eight (45) quarts. Additionally or alternatively, without departing from the scope of the disclosure described herein, the insulated container 100 may be configured to store materials in solid, liquid, or gaseous states or combinations thereof.

[0059] In at least some examples, the insulated container 100 (and various other containers described herein) may be sized to accommodate the volume of the contents described above. For example, the insulated container 100 may be at least seventeen (17) inches high, at least sixteen (16) inches wide, and at least fourteen (14) inches deep. Additionally or alternatively, without departing from the scope of the disclosure described herein, the insulated container 100 may be configured in different sizes (i.e., height, width, and depth).

[0060] As previously discussed, the insulated container 100 includes a cover 104. In some examples, the cover 104 may be press-fitted to the base 102 for a closed construction. Additionally or alternatively, other securing systems or devices may be used to secure the cover 104 to the base. FIG. 1AAs shown, the insulated container 100 may include a latching device 120 and a retainer 140 on the front of the base 102 to secure the lid 104 in a closed position. In some examples, the insulated container 100 includes at least one or more latching slots 141 integrally formed at the top of the base 102. The latching slots 141 may be configured to provide a recess, suitably sized to receive the latch 120 such that, when the lid 104 is in a closed and secured configuration, the latch 120 is flush with the latching slot 141. In other examples, when the lid 104 is in a closed and secured configuration, the latch 120 is flush with both the latching slot 141 and the retainer 140. In other configurations, the insulated container 100 may include a lid 104 and a base 102 forming at least one corner lifting flange 192 to facilitate easy gripping of the lid for opening. In other examples, the insulated container may include multiple corner lifting flanges 192. In some examples, the lifting flanges 192 may be formed by an integrally formed portion of the corners of the cap 104 and an integrally formed portion of the front corner at the top of the base 102. In still other configurations, the insulated container 100 may include a front lifting flange 191, which is integrally formed in the base 102. The front lifting flange 191 may be integrally formed at the top of the base 102. The lifting flanges are configured to provide an easily accessible area to the insulated container to allow an individual to grip the cap 104 for easy opening (i.e., one-handed operation).

[0061] In some examples, the cover 104 may be hinged such that it is removably or permanently attached to the base 102 at hinge 116 and can rotate about the hinge 116. The hinge may be one of various types of hinges, including continuous piano hinges, double hinges, ball joint hinges, movable hinges, etc. Hinge 116 may allow the cover 104 to be opened and rotated away from the base portion 102 to allow (e.g., via opening 112) access to the interior space defined by the base portion 102. That is, the hinge may facilitate the rotation of the cover 104 from a closed configuration of the insulated container (e.g., when the cover is in place covering the interior space formed by the base) to an open configuration (e.g., when the cover does not cover the interior space formed by the base), and vice versa. In some examples, the insulated container 100 is configured with at least one hinge 116. In another example, the insulated container is configured with multiple hinges. In other configurations, hinge 116 includes a first portion and a second portion, the first portion being integrally formed in the cover 104 and the second portion being integrally formed in the base 102. In yet another example, hinge 116 may also include at least one or more pin pockets 194 to secure the cover 104 to the base 102 via at least one hinge pin 195, thereby allowing the cover to rotate from a closed position to an open position. In other examples, multiple hinge pins 195 secure the cover 104 to the base 102.

[0062] In the example described herein, the base 102 and the cover 104 may include an outer surface or housing 117 that surrounds and encloses the insulating portion 118, such as FIG. 1C and FIG. 5A As shown. The housing 117 is typically formed of various materials, such as one or more metals, alloys, polymers, ceramics, or fiber-reinforced materials. In some examples, the housing 117 may be formed of a plastic material, such as polyethylene, which is molded to form both the base 102 and the cover 104 portions. In some examples, the insulating portion 118 is formed of an insulating material exhibiting low thermal conductivity. For example, the insulating portion 118 may be formed (or filled with) a polymer foam, such as polyurethane foam. Additional or other insulating materials may be used without departing from the invention. In some examples, the base 102 and cover 104 portions are formed using a rotational molding process (not shown) as understood by those skilled in the art. However, various other types of molding or other manufacturing processes (e.g., stamping, casting, forging, etc.) may be used to form the insulating container without departing from the invention.

[0063] In other embodiments, such as FIG. 3A-3C As shown, the insulated container 200 includes a reference FIG. 1A and FIG. 1BThe discussion focuses on latching devices 220 similar to those latching devices. That is, the latching device includes a retainer 240 at the base 202 on the front of the container 200 (e.g., similar to the retainer 140 on the container 100, such as...). FIG. 1A As shown, container 100 includes a latching device 120 to secure lid 104 in the closed position. Therefore, when lid 204 is in the fully closed position, the engaging portion of the latch (not shown) is received in and engages with retainer 240 formed on the front of insulated container 200 (as shown). FIG. 3A (As shown). In other configurations, the insulated container 200 may include a lid 204 and a base 202, the lid 204 and the base 202 forming at least one integrally formed corner lifting flange 292 to facilitate easy gripping of the lid for opening. In still other configurations, the insulated container 200 may include a front lifting flange 291, the front lifting flange 291 being integrally formed in the base 202.

[0064] Similar to the examples discussed above, retainers 140 and 240 can be respectively as follows: FIG. 1A and FIG. 3A The latch 220 is molded into the bases 102 and 202. A process similar to that described below can be used to engage / disengage the latch 220 from the retainer 240. In yet another embodiment, the base portion 202 may also include a carrying handle or carrying strap 207 (not shown). The carrying handle or carrying strap 207 may be attached to the pivot 209. In still another embodiment, the insulated container may lack a carrying handle or carrying strap and the pivot. In other embodiments, the insulated container 200 may include a pressure regulating device 210, which is arranged in the rear or back side 214 of the base 202, such as... FIG. 3C As shown. In other examples, the pressure regulating device 210 may be configured in the cover 204.

[0065] In other embodiments, the lid 204 of the heat-insulating container 200 may include a plurality of accessory magnets 205, such as FIG. 4AAs shown. Magnet 205 can be disposed on the top outer surface 203 of the cover 204. In some examples, the magnet may be generally disc-shaped or generally annular. In other examples, the magnet is configured to secure additional attachments to the top of the cover. In still other examples, magnet 205 is secured to the top of the cover via press fit or adhesive. In yet another example, magnet 205 is threaded and screwed into the cover 204. In still other examples, magnet 205 is secured to the top of the cover by fasteners 205a (as shown in Figure 10) such as screws, bolts, rivets, etc. Some examples of attachable and removable attachments may include cover pouches, plastic or wooden boards, cushions, or cover nets. The base portion 202 may include a first end 206 having a bottom surface 208. The bottom surface 208 may be configured to support the insulated container on a surface such as a table, floor, vehicle cargo box, ship deck, etc., and may include multiple legs 212, such as FIG. 4B As shown. The foot 212 can be configured to provide a non-slip or slip-free surface and can be configured to keep the insulation container 200 raised off the ground. In another example, the foot 212 can be configured to reduce friction with the ground or surface, so that the insulation container can be moved more easily while it is on the ground (i.e., the insulation container can be easily slid or pushed across the ground). The foot 212 can be constructed of rubber, foam, plastic, or other suitable materials. In yet another embodiment, the bottom surface 208 may include the logo or name of the company or manufacturer of the insulation container, which is embossed, integrally molded, or pressed into the housing 217, such as... FIG. 4B As shown. In some embodiments, the bottom bag 216 may be integrally formed in the bottom surface 208 of the base portion 202. The bottom bag 216 allows an individual to grip the base portion 202 from the bottom surface 208 to easily empty or pour out the contents of the insulated container (e.g., ice, melted ice, water, etc.).

[0066] FIG. 5A The lid 104 of the insulated container 100 is shown in a generally open position. FIG. 5C As shown, the cover 104 is in a generally closed but not fixed position. That is, the cover 104 is generally perpendicular to the base 102 and is covering the opening. To open the cover 104 and thus access the interior space defined by the base 102 of the insulated container 100, one can proceed along... FIG. 5AThe arrow shown in the image indicates that the cap 104 is lifted upwards. When the cap 104 is configured in the closed and fixed position, the cap seals the opening 112. The cap is configured to travel approximately 115° from the fully closed position to the fully open position. In some examples, the cap is configured to travel at least 90°, 95°, 100°, 105°, 110°, 115°, or 120° from the fully closed position to the fully open position. In other examples, the cap 104 may be configured to travel from approximately 90° to 120° in the fully open position. In some examples, the cap remains upright when configured in the fully upright position. Further examples can be found in [reference needed]. FIG. 1A , FIG. 1B , FIG. 3A-3C and FIG. 5A In order to open the cover 104 (e.g., to allow access to the interior space formed by the base 102), the hinged cover 104 can be rotated away from the base portion 102 and can rest along the rear side 114 of the base portion 102 (e.g., the cover) from the closed configuration (e.g., in FIG. 1A , FIG. 1B , FIG. 3A-3C and FIG. 5C Rotate at least 90° to the position shown in the image to open the structure (e.g., in the position shown in the image). FIG. 5A (as shown in the image). In some examples, the fully open position or configuration may include at least a portion of the top outer surface of the cover 104 contacting the rear (or other) side portion 114 of the base portion 102 of the insulated container 100.

[0067] like FIG. 5A As shown, some example insulated containers may include multiple foam plugs 130 located on the underside of the lid 104. In other examples, the foam plugs 130 may also include attachment clips 132. The attachment clips may be configured to engage with the bottom (i.e., underside) of the lid 104 and secure additional attachments or devices to the bottom (i.e., underside) of the lid 104 for easy storage. For example, a mesh attachment may be attached to multiple clips 132. In some examples, the mesh (not shown) may be constructed of flexible rubber and may prevent certain items from being exposed to water or ice residing in the interior space of the insulated container. Other attachments, such as trays or baskets, may be stored in the bottom of the interior space of the insulated container and / or may be configured to rest on top of the interior space. In some examples, the tray or basket may include a lip (not shown) around the perimeter of the tray, which allows the tray to hang from the edge of the opening 112 while remaining within the interior space of the insulated container. This construction allows the lid 104 to be configured in a closed and fixed position, thereby sealing the interior space while the tray or basket is secured in place inside / within the insulated container 100.

[0068] like FIG. 5A andFIG. 5B As shown, the underside of the cover 104 may include the logo or name of the company or manufacturer of the insulated container, which is embossed, integrally formed, or pressed into the bottom of the cover 104.

[0069] Furthermore, in some examples, the insulated container may include gaskets or other sealing devices. Gaskets may be disposed in the cap or base and may help seal the cap and base when the cap is closed and in a fixed configuration. In other examples, gaskets may be disposed in the cap or base and may provide a watertight seal when the cap is closed and in a fixed configuration. In some examples, gaskets may be disposed in a recess formed in at least one of the base and cap and extending around the periphery of at least one of the base or cap. In other examples, such as FIG. 5B As shown, gasket 150 can be disposed in gasket adapter 152, which is formed in at least one of base 102 or cover 104 and extends around the periphery of at least one of the base or cover. In other examples, gasket 150 may be constructed of rubber, silicone, or other suitable materials. Gaskets can help maintain the temperature of the contents or liquid contained within an insulated container. Various other gasket examples can be used with any of the insulated containers described herein.

[0070] In some examples, the gasket may include strategically placed cutouts that reduce or eliminate the need for vents (e.g., vents to prevent lid locking), as will be discussed more fully below. In some examples, the gasket may be a conventional gasket with a generally circular cross-section. In other examples, the gasket may have a specific cross-section configured to facilitate venting of the insulated container. In some examples, the cross-section is a V-shaped or generally V-shaped portion of the gasket. In still other examples, the gasket may also include at least one vent hole to allow passive venting of air or fluid into or out of the interior space when the insulated container is in a closed and secured configuration to prevent lid locking. In other examples, the gasket may include multiple vent holes. In still other examples, the gasket is configured to provide a watertight seal when the lid is in a closed and secured configuration.

[0071] In some examples, the cover 104 can be configured to be held in place or locked in a closed position using a latching device 120. The latching device 120 can be various types of latches, including latches having a latch portion and a retainer portion on the base 102, as well as various other types of latches.

[0072] FIG. 1A A latching device 120 is shown in a closed and fixed position, while FIG. 5CA latching device 120 is shown in an unsecured position while the cover 104 is in a closed but unsecured configuration. When in the secured position, the latching device 120 is positioned such that the cover 104 abuts against the base 102 of the insulated container 100, thereby closing, securing, and / or sealing the container. To disengage the latching device 120, as... FIG. 6A As shown, the gripping portion or lower latch portion 124 is pulled / flipped away from the base 102 of the container 100. In other words, the upper latch portion 123 is stretched, causing the lower latch engaging tab 125 to disengage from the latch retainer 140. Once the engaging tab 125 disengages from the latch retainer 140, the latch 120 moves away from the container and swings upward in an arc. FIG. 6A-6C As shown, the lower latch 124 can be pivotally attached and secured to the upper latch 123. The upper latch 123 can be pivotally attached and secured to the cover 104 of the insulated container 100.

[0073] Similarly, to close container 100, latching device 120 moves downward in an arc toward container 100. When the upper latch portion 123 and lower latch portion 124 move to latch retainer 140, lower latch portion 124 is rotated such that engaging tab 125 is positioned downward toward base 102, and engaging tab 125 is placed / positioned within retainer recess 142 in the bottom of retainer 140, as... FIG. 5CAs shown. The lower latch 124 is then rotated / pushed downwards until the lower latch 124 and the upper latch 123 are positioned and secured. When in the positioned and secured position, the upper latch 123 is stretched and tensioned, thereby maintaining a constant downward force on the cover 104, securing and sealing the cover 104 in the closed configuration. In some examples, the lower latch may be more rigid than the upper latch. In some examples, the upper latch may be more rigid than the lower latch. In still other examples, the engaging tab may be formed of a rigid material, and the lower latch may be formed of an elastomeric material. The lower latch and the engaging tab may be formed by co-molding or injection molding (e.g., multi-material injection molding). In other examples, the engaging tab of the lower latch is a rigid material, and the remainder of the lower latch is an elastomeric material. In some examples, the lower latch and the engaging tab may be formed of the same material. In another example, the upper and lower latch portions may not be elastic and / or may be semi-rigid. In this example, the washer is also configured to compress, thereby allowing the lower latch portion to be rotated so that the engaging tab can be positioned / positioned within a retainer recess in the bottom of the retainer, thereby securing the cover in the closed configuration. In some examples, the washer may also be configured as an elastic component (i.e., replacing the upper or lower latch portion) to provide the necessary clearance for engaging the lower latch portion engaging tab with the latch retainer. When in the positioned and fixed position, the upper and lower latch portions hold the cover in the position of the compressed washer. Thus, the washer maintains a constant force on the cover, thereby securing and sealing the cover in the closed configuration. Further, when in the positioned position, the upper latch portion 123 and lower latch portion 124 of the latch 120 may be substantially recessed within the latch groove 141, and in some examples, the latch mechanism 120 does not extend or protrude beyond its surface. In other examples, when the cover 104 is secured in the closed position / configuration, the latching device / mechanism 120 is generally rectangular in shape.

[0074] As will be understood by those skilled in the art, the upper latch 123 is made of a material and is sized such that sufficient force remains to maintain the closed position of the container lid 104 when it is in a closed / positioned and fixed position. In other words, a certain amount of tension is maintained on the upper latch 123 in the closed position because the upper latch 123 does not fully return to its unstretched position / state. In some examples, the upper latch 123 may be an elastomeric rubber, and the lower latch 124 may be a rigid plastic or composite material. In other examples, the upper latch 123 may be a rigid plastic or composite material, and the lower latch 124 may be an elastomeric rubber. In still other examples, the upper latch 123 may be constructed of elastomeric rubber and / or rigid plastic or composite material. In yet another example, the lower latch 124 may be constructed of elastomeric rubber and / or rigid plastic or composite material. In some examples, the upper latch 123 and / or the lower latch may be constructed wholly or partially of a semi-rigid material and / or a semi-elastomeric material. In another example, both the upper latch portion 123 and the lower latch portion 124 are made of elastomeric rubber. In yet another example, both the upper latch portion 123 and the lower latch portion 124 are made of rigid plastic or composite material. In the closed position, the engaging tab 125 of the lower latch portion 124 is received within a recessed groove 142 of the latch retainer 140. In some exemplary examples, the engaging tab 125 is sized and shaped to provide maximum contact with the recessed groove 142, thereby ensuring a closure that can be easily maintained.

[0075] Reference FIG. 6A-6C An example latching device 120 that can be used with the insulated container 100 is described. The latching device 120 shown and described is merely one example latch that can be used, and various other types of latches can be used without departing from the invention.

[0076] FIG. 6A-6C These are front, perspective, and rear views of an example latching device 120 for securing a lid in a closed configuration. The latching device 120 includes an upper latch portion 123 and a lower latch portion 124. The lower latch portion also includes an engaging tab 125 configured to engage a recess or groove 142 formed on the bottom of the retainer portion 140. The lower latch portion may also include a finger lift 126 positioned opposite the engaging tab 125. In other examples, the finger lift 126 may extend outward and distally from or from the insulated container lid 104.

[0077] According to one aspect of the invention, the upper latch 123 is made of a flexible, stretchable, elastic, elastomeric, one-piece molded material, which is typically pivotally / hinged to the lid portion 104 of the container 100 and received within a recessed elongated latch groove 145, which is typically integrally molded to the container 100. In some examples, the latch groove may be integrally molded as part of both the lid 104 and the bottom portion 102. The upper latch 123 and the lower latch 124 may be molded from a rubber material into a one-piece construction, as will be understood by those skilled in the art. The upper latch 123 and the lower latch 124 may also be formed from a material, such as a plastic material or another suitable material, which may be formed or molded into a shape and thus retain its formed shape. The upper latch 123 and the lower latch 124 can be made to have sufficient size, thickness and construction material to withstand repeated stress cycles as the latch 120 engages / disengages from the latch retainer 140 over time.

[0078] As in FIG. 6A-6C Further depicted, the upper latch 123 may include a base 300, a first arm 302, and a second arm 304. The first arm 302 and the second arm 304 may be generally perpendicular to the base 300. The first arm 302 may be generally parallel to the second arm 304. The upper latch 123 may be generally shaped like an inverted U. In other examples, the lower latch 124 includes an engaging tab 125. The engaging tab 125 may be configured to pivotally rotate within / between the first arm 302 and the second arm 304 of the upper latch. In another example, as... FIG. 1A The retainer 140 shown can be located between the upper first arm 302 and the upper second arm 304 of the latch, and below the upper base 300 of the latch. FIG. 1A It is further shown that when the insulated container lid is in the closed and fixed configuration, the retainer 140 can be flush with the upper base 300 of the latch, the first arm 302, the second arm 304 and the lower part 124 of the latch.

[0079] FIG. 6B and FIG. 6C The diagram shows that the lower latch portion 124 can be pivotally attached to the upper latch portion 123 and secured to the upper latch portion 123 by a lower latch portion pin 122. The upper latch portion 123 can be pivotally attached to the cover 104 and secured to the cover 104 by an upper latch portion pin 121, as shown. FIG. 5C As shown.

[0080] In some examples, the latch 120 is configured such that the finger lift 126 extends from the lower latch portion 124 at an angle offset from the plane of the latch 120. The angle between the finger lift 126 and the lower latch portion 124 and the upper latch portion 123 can facilitate or make it easier for a user to grasp the finger lift 126. At this angle, the user can easily slide his or her finger between the finger lift 126 and the side of the base portion 102 of the insulated container 100 to disengage the latch 120 from the retainer 140. Furthermore, because the upper latch portion 123 is made of a resilient material, the finger lift 126 is not easily displaced or damaged even if it extends from the body of the container.

[0081] like FIG. 6B As best shown, the finger lifter 126 is typically shaped for easy gripping or access by the user. Other shapes and geometries may be conceived for the finger lifter 126 to suit the operation of the latch 120, without being intended to be limited thereto.

[0082] Similar to the examples discussed above, another feature of the latch mechanism or device 120 is that the latch retainer 140 can be integrally formed within the base portion 102. The latch retainer 140 can be positioned within an elongated retainer groove 141. As previously discussed, the latch retainer may include a recess or slot 142 formed in the bottom of the retainer 140. The recessed recess 142 is typically configured to receive an engaging tab 125 of the lower latch portion 124. In other examples, the latch retainer 140 may be generally square or generally rectangular in shape. Similarly, the elongated retainer groove 141 may be generally rectangular in shape. This combination of features provides a robust and very secure cover latch system.

[0083] FIG. 7A-7B Another example of an insulated container 400 is shown, with the cover removed to better show the interior space 412. In some examples, at least one pressure regulating device 410 may be configured in the rear portion 414 of the base 402. The pressure regulating device 410 may be configured to regulate the internal pressure of the interior space 412 using external atmospheric pressure. The pressure regulating device 410 may be permanently attached or removably inserted into an aperture (not shown) integrally formed in the rear portion 414. In some examples, the pressure regulating device may include an exhaust port 402 positioned on the interior rear portion 414 and within the interior space 412. In some examples, the exhaust port 402 may include a plurality of umbrella-shaped valve exhaust ports 411 configured to allow air to pass through and be released unidirectionally from the interior space 412 via an umbrella-shaped valve 500, such as... FIG. 8A and FIG. 8BAs shown. The pressure regulating valve may also include an exhaust gasket 406, an umbrella-shaped valve gasket 408, and an exhaust rod 404, as shown. FIG. 8B As shown. In some examples, the exhaust rod 404 may include multiple ribs configured to provide a frictional or press-fit in generally cylindrical holes integrally formed in the rear portion 414. In other configurations, the pressure regulating device may be secured in the rear portion 414 by adhesives, RF welding, etc. In another example, an umbrella valve 500 may be configured within and above the rod 404 and the umbrella washer 408. In other examples, the pressure regulating device may also include a duckbill valve 504 within the rod 404.

[0084] like FIG. 8A , FIG. 9A and FIG. 9B As shown, the pressure regulating device 410 may include an umbrella valve 500 and a duckbill valve 504. The duckbill valve 504 and the umbrella valve 500 may be configured to allow passive air flow into and out of the internal space 412 of the insulation container 400 to regulate the internal pressure of the insulation container 400 and to bring the internal pressure of the insulation container 400 equal to atmospheric pressure. In one example, the umbrella valve 500 is an elastomeric valve with a diaphragm-shaped sealing disc 506 that creates a seal above the umbrella valve vent 411. When the pressure within the internal space 412 reaches a predetermined level, a suitable force is applied to lift the convex diaphragm 506 from the umbrella valve vent 411 to allow air to flow in a unidirectional direction (i.e., out of the internal space 412). The diaphragm 506 is also configured to prevent immediate backflow of air in the opposite direction. Thus, for example, when atmospheric pressure decreases (e.g., climbing a hill or driving uphill), the pressure regulating device reduces the pressure within the insulation container. In other examples, the pressure regulating device 410 may also include a duckbill valve 504. The duckbill valve 504 includes a channel 502 configured to allow air to enter the interior space 412 from the outside of the insulation container 400 when the internal pressure of the interior space 412 is less than atmospheric pressure. In another example, the duckbill valve 504 may be a one-piece elastomeric component including the channel 502. The valve 504 may include an elastomeric lip 508 generally shaped like a duckbill, configured to prevent fluid backflow from the interior space 412, and configured to allow air to flow into the interior space 412 when atmospheric pressure is greater than the internal pressure of the insulation container 400 (e.g., coming down a hill or driving downhill).

[0085] FIG. 10A-23 Another example of an insulated container 600 is shown, according to one or more aspects described herein. For FIG. 10A-23 In some embodiments, similar reference numerals under the “6xx” series are used to designate features, rather than as in FIG. 1A / FIG. 1B / FIG. 1C The “1xx” used in the embodiments, such as in FIG. 3A / FIG. 3B / FIG. 3C The “2xx” used in the embodiments, or as in FIG. 7A / FIG. 7B The "4xx" feature is used in the embodiments. The "6xx" feature can be similar to the "1xx", "2xx", or "4xx" feature. Therefore, the above has already referred to... FIG. 1A / FIG. 1B / FIG. 1C , FIG. 3A / FIG. 3B / FIG. 3C and FIG. 7A / FIG. 7B Certain features of the insulated container 600 described in the description of insulated containers 100, 200, or 400 may be described in less detail, or may not be described at all. Additionally, references above... FIG. 1A-9B Any features described in the insulation containers 100, 200 and 400 can be used with the insulation container 600.

[0086] FIG. 10A A front view of the insulated container 600 is depicted. FIG. 10B and FIG. 10D A side view of the insulated container 600 is depicted. FIG. 10C A rear view of the insulated container 600 is depicted. FIG. 10E A front perspective view of the insulated container 600 is shown.

[0087] In one example, the insulated container 600 may include a base portion 602 and a lid 604, in some examples where the lid 604 may be non-destructively and removably coupled to the base portion 602. The base portion 602 may be an insulated structure forming an internal space for containing contents or liquid. In some examples, the base portion 602 may be cubic or substantially cubic in shape. In still other examples, the base portion 602 may be substantially cylindrical or may have a substantially rectangular cross-section. Various other shapes may be used without departing from the invention.

[0088] The base portion 602 may include a first end portion 606 having a bottom surface 608. The bottom surface 608 may be configured to support the insulated container on a surface such as a table, the ground, a vehicle cargo box, a ship deck, etc.

[0089] The base portion 602 also includes a second end portion 610, which defines an opening 612 (in FIG. 11 As shown in the image, opening 612 can be used to access the interior space of the insulated container. FIG. 11A top perspective partial view of the insulated container 600 is shown, with the lid 604 open. When the insulated container 600 is in use (e.g., when the insulated container 600 is in a closed configuration), the opening 612 can be covered by the lid 604. The base portion 602 may also include a plurality of side portions 614 attached to a bottom surface 608, defining spaces for receiving contents within the insulated container 600. The side portions 614 may be arranged such that they extend substantially perpendicularly from the bottom surface 608. The plurality of side portions 614 may include: a front side portion 614A; a rear side portion 614B opposite to the front side portion 614A; and two lateral side portions 614C located between the front side portion 614A and the rear side portion 614B.

[0090] In some examples, one or more side pocket handles 690 may be arranged in one or more side portions 614 (or other areas of the base portion 602). The side pocket handles 690 may be integrally formed with the base portion 602 and may typically be an undercut or slit formed in the side portion 614 of the base 602. In some examples, (such as in...) FIG. 10B and FIG. 10D The undercut or cutout forming the side pocket handle 690 (as shown in the diagram) may include a recess that extends substantially all or most of the length of the side portion 614. This can provide an easy-to-manufacture base 602 with a one-piece handle 690. In some examples, the side pocket handle 690 may be flush with the outer surface of the base 602 to reduce the risk of breakage.

[0091] As discussed above, the insulated container 600 can be configured to contain, store, carry, or otherwise carry a certain volume of contents or possibly liquids. In some examples, the insulated container 600 can be configured to store approximately 60 liters (approximately 63.4 quarts) or 48 liters (approximately 50.7 quarts). In some examples, the insulated container 600 can be configured to store contents between twenty-two (22) quarts and twenty-eight (28) quarts. In some examples, the insulated container 600 can be configured to store approximately twenty-four (24) quarts of contents. In other examples, the insulated container 600 can be configured to store at least twenty-two (22) quarts of contents, or the insulated container can be configured to store at least twenty-eight (28) quarts of contents, etc. In yet another example, the insulated container 600 may be configured to store approximately sixteen (16) quarts of contents, twenty-four (24) quarts of contents, thirty-six (36) to thirty-eight (38) quarts of contents, or forty-eight (48) to fifty-eight (58) quarts of contents. In still another example, the insulated container 600 may be configured to store contents between approximately fourteen (14) quarts and approximately forty-five to twenty-eight (45) quarts. Additionally or alternatively, without departing from the scope of the disclosure described herein, the insulated container 600 may be configured to store materials in a solid, liquid, or gaseous state, or a combination thereof.

[0092] In at least some examples, the insulated container 600 (and various other containers described herein) may be sized to accommodate the volume of the contents described above. For example, the insulated container 600 may be at least seventeen (17) inches high, at least sixteen (16) inches wide, and at least fourteen (14) inches deep. Additionally or alternatively, without departing from the scope of the disclosure described herein, the insulated container 600 may be configured in different sizes (i.e., height, width, and depth).

[0093] As previously discussed, the insulated container 600 includes a cover 604. In some examples, the cover 604 may be press-fitted to the base 602 for a closed construction. Additionally or alternatively, other securing systems or devices may be used to secure the cover 604 to the base. FIG. 10A and FIG. 10E As shown, the insulated container 600 may include a latching device 620 and a retainer on a base 602 at the front of the container to secure the lid 604 in a closed position. In some examples, the lid 604 may be configured to be held fixed or locked in a closed position using the latching device 620. The latching device 620 may be of various types of latches, including latches having a latch portion and a retainer portion on the base 602, and various other types of latches. The insulated container 600 may include as described above and FIG. 1A , FIG. 1B , FIG. 3A ,FIG. 4A , FIG. 5A , FIG. 5C , FIG. 6A , FIG. 6B and FIG. 6C Any latching devices and retainers specifically shown in the diagram.

[0094] In such FIG. 10E In other configurations shown, the insulated container 600 may include a lid 604 and a base 602, the lid 604 and base 602 forming at least one corner lifting flange 692 to facilitate easy gripping of the lid for opening. In other examples, the insulated container 600 may include multiple corner lifting flanges 692. In some examples, the lifting flange 692 may be formed by an integrally formed portion of the corner of the lid 604 and an integrally formed portion of the front corner at the top of the base 602. In still other configurations, the insulated container 600 may include a front lifting flange 691, the front lifting flange 691 being integrally formed in the base 602. The front lifting flange 691 may be integrally formed at the top of the base 602. The lifting flange 691 may be configured to provide an easily accessible area to the insulated container 600 to allow an individual to grip the lid 604 for easy opening (i.e., one-handed operation).

[0095] In some examples, the cover 604 may be hinged such that it is removably or permanently attached to the base 602 at hinge 616 and can rotate about hinge 616. The hinge may be one of various types of hinges, including continuous piano hinges, double hinges, ball joint hinges, movable hinges, etc. Hinge 616 may allow the cover 604 to be opened and rotated away from the base portion 602 to allow (e.g., via opening 612) access to the interior space defined by the base portion 602. That is, hinge 616 may facilitate the rotation of the cover 604 from a closed configuration of the insulated container 600 (e.g., when the cover 604 is in place covering the interior space formed by the base 602) to an open configuration (e.g., when the cover 604 does not cover the interior space formed by the base 602), and vice versa. In some examples, the insulated container 600 is configured with at least one hinge 616. In another example, the insulated container is configured with multiple hinges 616. In other configurations, the hinge 616 includes a first part and a second part, the first part being integrally formed in the cover 604 and the second part being integrally formed in the base 602.

[0096] In the examples described herein, the base 602 and the cover 604 may include an outer surface or housing that surrounds and encloses the insulating portion, such as FIG. 1C and FIG. 5AAs shown and described. The housing is typically formed of various materials, such as one or more metals, alloys, polymers, ceramics, or fiber-reinforced materials. In some examples, the housing may be formed of a plastic material, such as thermoplastic olefin elastomer (TPO), polypropylene with a rubberizing agent, or polyethylene, which is molded to form both the base 602 and the cap 604 portions. Thermoplastic olefin elastomer (TPO) consists of polypropylene, polyethylene, or other polyolefins as hard segments and a rubber component, such as ethylene propylene rubber (EPM) or ethylene propylene diene monomer (EPDM), as soft segments. In some examples, the insulating portion is formed of an insulating material exhibiting low thermal conductivity. For example, the insulating portion may be formed (or filled with) a polymer foam, such as polyurethane foam. Additional or other insulating materials may be used without departing from the invention. In some examples, the base 602 and cap 604 portions are formed using an injection molding process (not shown) as understood by those skilled in the art. However, without departing from the present invention, various other types of molding or other manufacturing processes (e.g., rotational molding, stamping, casting, forging, etc.) can be used to form the insulated container.

[0097] The base portion 602 may include a first end portion 606 having a bottom surface 608. The bottom surface 608 may be configured to support the insulated container 600 on a surface such as a table, floor, vehicle cargo box, ship deck, etc., and may include multiple legs, as described above and in… FIG. 4B As shown in the image. In another example embodiment, the bottom surface 608 of the insulated container 600 may include one or more lateral supports 613, such as... FIG. 19 As shown. Lateral support feet 613 or feet can be configured to provide a non-slip or slip-free surface and can be configured to keep the insulation container 600 elevated off the ground. In another example, lateral support feet 613 or feet can be configured to reduce friction with the ground or surface, allowing the insulation container to be moved more easily while it is on the ground (i.e., the insulation container can be easily slid or pushed across the ground). Lateral support feet 613 can be separate and parallel, creating and providing an air gap between the bottom surface 608 of the insulation container and the ground. Lateral support feet 613 or feet can be constructed of rubber, foam, plastic, or other suitable materials. In another embodiment, lateral support feet 613 can be molded into the base 602 in a mold for the lateral support feet 613 with an alternative surface treatment or texture. In yet another embodiment, the bottom surface 608 can include the logo or name of the company or manufacturer of the insulation container, which is embossed, integrally molded, or pressed into the housing.

[0098] FIG. 11 , FIG. 15 andFIG. 16A The cover 604 of the insulated container 600 is shown in a generally open position. FIG. 10A-10E As shown, the cover 604 is in a generally closed configuration. That is, the cover 604 is generally perpendicular to the base 602 and is covering the opening. In order to open the cover 604 and thus access the internal space defined by the base 602 of the insulated container 600, the cover 604 can be lifted upward. When the cover 604 is configured in the closed and fixed position, the cover 604 seals the opening 612.

[0099] In addition, in some examples, such as FIG. 11 As shown, the insulated container 600 may include a gasket 650 or other sealing device. The gasket 650 may be disposed in the cap 604 or the base 602 and may contribute to sealing the cap 604 and base 602 when the cap 604 is in a closed and fixed configuration. In other examples, the gasket 650 may be disposed in the cap 604 or the base 602 and may provide a waterproof or near-waterproof seal when the cap 604 is in a closed and fixed configuration. In some examples, the gasket 650 may be disposed in a recess formed in at least one of the base 602 and the cap 604 and extending around the periphery of at least one of the base 602 or the cap 604. In other examples, such as FIG. 11 As shown, gasket 650 can be disposed in gasket adapter 652, which is formed in at least one of base 602 or cap 604 and extends around the periphery of at least one of base 602 or cap 604. In other examples, gasket 650 can be constructed of rubber (such as neoprene or EPDM), silicone, or other suitable materials. Gasket 650 can help maintain the temperature of the contents or liquid contained within the insulated container 600. Various other gasket examples can be used with any of the insulated containers described herein.

[0100] In some examples, gasket 650 may include strategically placed cutouts that can reduce or eliminate the need for vents (e.g., vents to prevent cap locking), as will be discussed more fully below. Gasket 650 may include cutouts, or cap 604 or base 602 may include variations in geometry to allow for reduced or eliminated compression in gasket 650. Variations in the geometry of base 602 or cap 604 can reduce compression in gasket 650 and allow venting when the internal pressure of the insulation container 600 reaches a certain level. In some examples, gasket 650 may be a conventional gasket with a generally circular cross-section. In other examples, gasket 650 may have a specific cross-section configured to facilitate venting of the insulation container. In some examples, the cross-section is a V-shaped or generally V-shaped portion of gasket 650. In still other examples, gasket 650 may also include at least one vent hole to allow passive release of air or fluid into or out of the interior space when the insulation container 600 is in a closed and fixed configuration to prevent cap locking. In other examples, gasket 650 may include multiple drainage holes. In still other examples, gasket 650 is configured to provide a waterproof seal when cap 604 is in a closed and secured configuration.

[0101] In other examples, the insulated container 600 may include a handle assembly 660, such as FIG. 12A-18 As specifically shown in the text. FIG. 12A-12C A side view of the insulated container 600 is shown, which shows the handle assembly 660 in various retracted and extended configurations. FIG. 13 A side view of the insulated container 600 in an inclined configuration and the handle assembly 660 in an extended configuration is shown. FIG. 14 A rear perspective view of the insulated container 600 is shown, with the handle assembly 660 in a retracted configuration.

FIG. 17A A side view of the handle assembly 660 in both the retracted and extended positions is shown. FIG. 17B and FIG. 17C Showing from FIG. 17A A close-up side view of the handle component area. Finally, FIG. 18 A close-up perspective view of the handle buffer area of ​​the handle assembly 660 is shown.

[0102] FIG. 12A-18A handle assembly 660 is shown that allows a user to ergonomically manipulate the insulated container 600. The handle assembly 660 can assist the end opposite the wheel 672 to leave the container's resting surface when the insulated container 600 is tilted to a rolling position. FIG. 12A-12C This shows when the handle assembly 660 is in FIG. 12A The collapsed structure shown in the middle is transformed into... FIG. 12C The handle assembly 660 in the extended position. For example... Figures 12A-12C As shown, the handle assembly 660 can be a telescopic handle design with a three-stage handle / arm structure. Figure 12A The handle assembly 660 at the first level is shown, wherein the handle assembly 660 is in a retracted (or folded back or nested) configuration. Figure 12B A handle assembly 660 in the second stage is shown, wherein the handle assembly 660 is in a partially extended configuration. Figure 12C A handle assembly 660 at the third stage is shown, wherein the handle assembly 660 is in a fully extended configuration. The handle assembly 660 may have one or more locking mechanisms 665A, 665B for a retracted configuration, a partially extended configuration, and / or a fully extended configuration.

[0103] Handle assembly 660 can be attached to the side portion 614 of base 602, and particularly the rear portion 614B of base 602. Handle assembly 660 can be arranged on the same rear portion 614B, which includes wheel assembly 670. When handle assembly 660 is in an extended configuration, a user can grip handle 662 to tilt and lift the front portion 614A, which transfers the weight of the insulated container 600 to the wheel 672 and allows the user to pull the insulated container 600. Handle assembly 660 can have an extended configuration that enables the user to pull the container 600. Figure 13 An inclined insulated container 600 is shown, with the handle assembly 660 fully extended. The handle assembly 660 may have a retracted configuration in which the handle assembly 660 may be flush with the top of the insulated container 600. When the handle assembly 660 is in the retracted configuration, the upper surface 663 of the handle 662 may be substantially parallel to the upper surface of the cover 604.

[0104] Handle assembly 660 can be attached to rear portion 614B. Handle assembly 660 may include one or more brackets 666A, 666B, 666C, which attach handle assembly 660 to rear portion 614B. Handle assembly 660 may include one, two, three, or four or more brackets to attach handle assembly 660 to rear portion 614B. One or more brackets may include: a first bracket 666A (or upper bracket) attached to the top portion of handle assembly 660; a second bracket 666B (or middle bracket) attached to the middle portion of handle assembly 660; and a third bracket 666C (or lower bracket) attached to the lower portion of handle assembly 660. Figure 14 and Figure 15 As shown, the first bracket 666A, the second bracket 666B, and the third bracket 666C can all be connected to the lower arm 664C, and in particular, the lower arm 664C and the handle assembly 660 are attached to the rear portion 614B. The brackets 666 can be mounted to mounting points on the rear portion 614B of the base 602 before the insulation (foam) is filled into the base 602.

[0105] Additionally, brackets 666A, 666B, and 666C may be U-shaped brackets, which are fitted around the outside of the lower arm 664C of the handle assembly 660 so that the lower arm 664C and the handle assembly 660 remain abutting against the rear portion 614B of the insulated container 600. Brackets 666A, 666B, and 666C may be various other shapes without departing from embodiments of the invention. Additionally, brackets 666A, 666B, and 666C may be of various widths. Figure 14 and Figure 15 In the exemplary embodiment shown, the first bracket 666A and the third bracket 666C may include a first width. The second bracket 666B may include a second width smaller than the first width. Brackets 666A, 666B, and 666C may include one or more fasteners 667 on each side of the brackets 666A, 666B, and 666C, the one or more fasteners 667 connecting the brackets 666A, 666B, and 666C to the rear portion 614B of the insulation container 600. In the exemplary embodiment, the first bracket 666A and the third bracket 666C may include two fasteners 667 on each side of the brackets 666A, 666C, the two fasteners 667 connecting the brackets 666A, 666C to the rear portion 614B of the insulation container 600. The second bracket 666B may include one fastener 667 on each side of the second bracket 666B, the one fastener 667 connecting the second bracket 666B to the rear portion 614B of the insulation container 600.

[0106] like Figure 16A , Figure 16B , Figure 17A , Figure 17B and Figure 17C As shown, the handle assembly 660 may include a telescopic feature. The handle assembly 660 may include an upper arm 664A, a middle arm 664B, and a lower arm 664C. The upper arm 664A can be nested inside the middle arm 664B and is slidable within the middle arm 664B. Additionally, the middle arm 664B can be nested inside the lower arm 664C and is slidable within the lower arm 664C. This nesting and sliding of the upper arm 664A, middle arm 664B, and lower arm 664C creates the telescopic feature of the handle assembly 660.

[0107] Figure 16A and Figure 16B A handle assembly 660 in an extended configuration is shown, with the cover 604 open. The cover 604 may be a thin cover, allowing it to be fully opened when the handle assembly 660 is in a fully extended configuration. In another embodiment, the cover 604 may include a thin seat, allowing the cover 604 with the seat to be fully opened when the handle assembly 660 is in a fully extended configuration.

[0108] like Figure 16A and Figure 16B As further shown, the cover 604 may include a stepped portion 605 located at the back of the cover 604. The stepped portion 605 can be inserted from the topmost surface of the cover 604 closest to the rear portion 614B. In one embodiment, the stepped portion 605 can be inserted approximately 1 / 2 inch from the topmost surface of the cover 604. In other embodiments, without departing from the invention, the stepped portion 605 can be inserted 1 / 4 inch, 3 / 4 inch, 1 inch, 1-1 / 2 inch, or other sizes from the topmost surface of the cover 604. The stepped portion 605 can help eliminate the risk of pinching between the intermediate arm 664B and the cover 604. The stepped portion 605 can include various shapes and sizes without departing from the invention.

[0109] Figure 17A , Figure 17B and Figure 17C The internal components of the handle assembly 660 are shown in detail. Figure 17ASpecifically, a handle assembly 660 is shown in both a partially extended configuration and a fully extended configuration. The handle assembly 660 may include one or more locking mechanisms, namely an upper locking mechanism 665A and a lower locking mechanism 665B. Locking mechanisms 665A and 665B may be mounted between arms 664A, 664B, and 664C for latching and locking the handle assembly 660 in the retracted configuration and / or the fully extended configuration. Specifically, the upper locking mechanism 665A may be mounted between the upper arm 664A and the intermediate arm 664B. The lower locking mechanism 665B may be mounted between the intermediate arm 664B and the lower arm 664C. A release button 668 may be connected to the locking mechanisms 665A and 665B and act as an actuator for the locking mechanisms 665A and 665B. The locking mechanisms 665A and 665B can be released using the release button 668 on the handle 662. The locking mechanisms 665A and 665B may include various components known and used in the art for telescopic handles, such as actuators, hinges, spring-loaded bearings, bushings, locking pins, locking holes, etc.

[0110] Additionally, such as Figure 17B and Figure 17C As shown, the handle assembly 660 may include extension arm overlap distances D1 and D2. The extension arm overlap distances D1 and D2 can be defined as the overlap between nested arms when arms 664A, 664B, and 664C are in an extended configuration. The extension arm overlap distances D1 and D2 allow for greater contact with the inner portions of the arms and bushings, resulting in a more robust and stable handle assembly 660 in the extended configuration. The handle assembly 660 may include an extended upper arm overlap distance D1, which represents the distance between the bottom of the upper arm 664A and the top of the middle arm 664B when the upper arm 664A and middle arm 664B are in a locked configuration and fully extended. The handle assembly 660 may further include an extended lower arm overlap distance D2, which represents the distance between the bottom of the intermediate arm 664B and the top of the lower arm 664C when the intermediate arm 664B and the lower arm 664C are in a locked configuration and fully extended. The extended arm overlap distances D1 and D2 may be approximately 70 mm. Without departing from the invention, the extended arm overlap distances D1 and D2 may also be other distances.

[0111] like Figure 18 As shown, the handle assembly 660 may include a handle 662. A user can grip the handle 662 to extend the handle assembly 660 into the extension configuration. The user can grip the handle 662 in the extension configuration to tilt and lift the front portion 614A, which transfers the weight of the insulation container 600 onto the wheel 672 and allows the user to pull the insulation container 600.

[0112] Handle 662 may include handle damper 669. Handle damper 669 may be located on each of the handle arms 664 of handle 662. When the insulated container 600 is tipped over / if the insulated container 600 is tipped over, handle damper 669 may be used to prevent wear on the handle grip 663 on handle 662. Handle damper 669 may include a protrusion that extends circumferentially around and / or around the upper handle arm 664A of handle 662 adjacent to the upper handle arm 664A. The protrusion may extend circumferentially around handle 662 and / or handle arm 664 partially or completely.

[0113] The handle assembly 660 can be formed from a polymer material, which can be a filled or unfilled polymer. For example, the polymer material can be PC-ABS, polyethylene, or other similar materials. Furthermore, the handle assembly 660 can be manufactured using polymer processing techniques, such as through various molding and casting techniques or other known techniques. Alternatively or optionally, the handle assembly 660 can be formed from a metallic material, such as aluminum alloy, magnesium alloy, or other metallic materials having a density of less than 3 g / cc. Alternatively, components of the insulated container 600, such as the lid, body, lid support member, and handle assembly, can include a structural foam having a composite polymer material with a low-density foam core and a higher-density polymer outer layer.

[0114] In other examples, the insulated container 600 may include a rear wheel assembly 670, such as Figures 10A-10D and Figures 19-21 As specifically shown in the text. Figure 19 A bottom perspective view of the insulated container 600 is shown, which shows the wheel assembly 670. Figure 20A and Figure 20B A rear cross-sectional view of the wheel assembly 670 and shaft attachment for the insulated container 600 is shown. Figure 21 A rear cross-sectional view of the shaft attachment and anti-rotation mount of the wheel assembly 670 for the insulated container 600 is shown.

[0115] The insulated container 600 may include a wheel assembly 670, which includes a pair of wheels 672 to assist a user in easily moving the insulated container 600. The wheel assembly 670 may include a tire 671 and wheels 672, wherein each wheel 672 can be mounted to a base 602 via an axle 674. The wheel assembly 670 may include a single axle 674 or a dual axle 674, with a single axle 674 for both wheels 672 and a dual axle 674 having an axle for each wheel 672. The tire 671 may be made of polyurethane foam with a hardness of approximately 80 Shore A and a density of 0.75 kg / L. The wheel 672 may be made of a rigid material, such as glass-filled nylon. The tire 671 may be overmolded, stretch-fitted, or grip-fitted over the wheel 672. The wheel 672 may include ribs or other gripping structures on the inner rim of the wheel 672 to aid in gripping the foam tire 671.

[0116] Each wheel assembly 670 and wheel 672 can be mounted to the base 602. More specifically, each wheel 672 can be mounted adjacent to the bottom surface 608 of the insulation container 600 to the rear portion 614B. Each wheel 672 can be secured to a wheel recess 673 on the base portion 602 and to the rear portion 614B. Each wheel 672 can be secured within the recess 673 using at least one spring retaining ring 675 and connected to at least one axle 674. Additionally, the wheel 672 and tire 671 can extend rearward beyond the handle assembly 660, thereby providing additional end protection to the handle assembly 660. Additionally, when the insulation container 600 is laid flat on the ground, the wheel 672 and tire 671 can be above the ground. The tire 671 may also include a flat tread profile for improved performance on sandy / soft terrain. The wheel 672 may also include a single-walled hub for providing a lighter weight. Additionally, the flatter and thinner tread profile of tire 671 can provide a lighter wheel.

[0117] Figure 20A and Figure 20B An exemplary embodiment of the wheel assembly 670 is specifically illustrated, showing a wheel 672 and a shaft 674 for an insulated container 600. The wheel assembly 670 may include one or more ball bearings 677A, an inner spacer 677B, and an outer spacer 677C, the outer spacer 677C setting the distance between the bearings 677A. The inner spacer 677B may be made of aluminum. The outer spacer 677C may be made of rigid polypropylene and may be used to position the wheel 672. The wheel 672, the inner spacer 677B, the outer spacer 677C, and the wheel eyelet 676 may be held along the axis of the shaft 674 by a spring retaining ring 675 along the end of the shaft 674. The spring retaining ring 675 may be radially fitted around the end of the shaft 674 to hold the shaft 674 through the wheel 672 and retain the shaft 674 within the base 602.

[0118] Additionally, wheel assembly 670 may include wheel eyelet 676. Wheel eyelet 676 may be located between wheel recess 673 and outer spacer 677C. Wheel eyelet 676 may also be positioned around shaft 674. Wheel eyelet 676 may provide a seal between wheel recess 673 and inner portion of base 602. Wheel eyelet 676 may be a rubber / non-rigid material (such as EPDM rubber). Wheel eyelet 676 may be used to prevent water or other materials from entering the insulation center of base 602. Wheel eyelet 676 may be a bushing or eyelet to absorb vibrations or forces impacting wheel 672, and to absorb vibrations and cushion shaft 674. By absorbing vibrations, wheel eyelet 676 may allow shaft 674 to rotate when high forces are applied to wheel 672. For example, during a drop test simulating the fall of insulation container 600 and the insulation container 600 being loaded with approximately 75 pounds, wheel assembly 670 will not be damaged due to wheel eyelet 676. The full force from the drop can be concentrated on the axle 674, rather than on the wheel 672. The force from the drop can be absorbed and / or dissipated by the wheel eyelets 676, thereby reducing and preventing high vibrations from reaching the base 602, axle 674, axle support 678, and other critical components. Drop testing may include dropping the insulated container 600 from approximately one meter above the ground under cold, hot, and room temperature conditions. The insulated container 600 may be dropped in multiple orientations, including being dropped on its back with impact force applied to both wheels 672, and being dropped on the corner of a wheel with force applied to a single wheel 672.

[0119] Figure 21 An exemplary embodiment of a shaft bracket 678 for preventing rotation and disengagement of shaft 674 is specifically shown. Shaft bracket 678 may be an anti-rotation mount abutting against base 602. Each shaft 674 may have at least one shaft bracket 678. Additionally, each shaft 674 may have multiple shaft brackets 678, such as two, three, or four shaft brackets 678. One or more shaft brackets 678 may be covered from view by handle assembly 660. Shaft bracket 678 may be attached to shaft 674 with fastener 679. Shaft 674 may include a flat section 674A having fastener attachment point 679A. The flat section 674A of shaft 674 may be compressed and permanently engage with the flat section 678A of shaft bracket 678. Shaft bracket 678 may include additional flat and engaging features 678B that contact and retain shaft bracket 678 against base 602. These flat sections 678A prevent the shaft 674 from rotating about the base 602 by keeping the shaft 674 stationary and in a permanent position in the base 602.

[0120] In other examples, the insulation container 600 may include a drain plug assembly 680, such asFigure 10C , Figure 19 , Figure 22 and Figure 23 As specifically shown in the text. Figure 19 A bottom perspective view of the insulated container 600 is shown, which shows the drain plug assembly 680. Figure 22 A side cross-sectional view of a drain plug assembly 680 for an insulated container 600 is shown. Figure 23 An exploded view of a drain plug assembly 680 for an insulated container 600 is shown.

[0121] like Figure 22 and Figure 23 As shown, the drain plug assembly 680 may include a main tube 682, an outer tube 694, and a washer 686. The drain plug assembly 680 may be positioned and mounted within a through-hole in the wall of the base portion 602. In the illustrated embodiment, the drain plug assembly 680 may be positioned adjacent to the bottom surface 608 of the insulated container 600 on the rear portion 614B. The drain plug assembly 680 may be mounted and positioned within a drain plug insert 609, which provides protection for the drain plug assembly 680. The drain plug assembly 680 may include a ratchet feature, wherein the main tube 682 (or inner tube) is keyed so that the main tube 682 cannot be rotated / opened when it is screwed into the outer tube 694.

[0122] The main pipe 682 may include a drain through-hole portion 685 having one or more ratchet keys 683 at a first end and a main pipe edge 681 at the opposite end. The main pipe 682 may also have an externally threaded connection 684 located between the main pipe edge 681 and the ratchet keys 683. The main pipe 682 may also include a washer 686. The washer 686 provides compression between the main pipe 682 and the inner wall 681 of the base 602. The washer 686 may include a radial feature 686A that helps to position the washer 686 against the main pipe edge 681 and the inner wall 618 of the base 602. The washer 686 may be a separate component, or the washer 686 may be molded into the main pipe 682. The washer 686 may be a softer material, such as silicone, while the main pipe 682 may be a more rigid material. The washer 686 may, for example, have a Shore A hardness of 40.

[0123] The outer tube 694 may also include a sealing ring 694A, which is inherent to the outer tube edge 695 of the outer tube 694. The sealing ring 694A contacts the rear portion 614B and the base outer wall structure 619. The outer tube 694 may include an internally threaded connection 698. The outer tube 694 may also include an outer tube edge 695 and a ratchet tooth 697 on the same end. The ratchet tooth 697 may be located on an inner portion of the outer tube 694. The outer tube 694 may also include a sealing ring 694A, which is inherent to the outer tube edge 695 of the outer tube 694. The sealing ring 694A may contact the rear portion 614B and the base outer wall structure 619. The sealing ring 694A may also provide a seal to prevent foam from escaping during assembly. The sealing ring 694A may be a single ring concentric about the axis of the outer tube 694. The sealing ring 694A may also include multiple rings or be non-circular.

[0124] like Figure 22 As shown, the main pipe 682 and the outer pipe 694 can be joined to form and produce a drain plug assembly 680. The main pipe 682 and the outer pipe 694 can pass through the rear portion 614B, the inner wall structure 618 of the base, and the outer wall structure 619 of the base. The main pipe 682 and the outer pipe 694 can be engaged with each other to produce the drain plug assembly 680 of the insulated container 600. The main pipe 682 can be installed first using a rectangular fitting having a flat portion 682A on the main pipe 682, which engages with a rectangular opening in the rear portion 614B and the inner wall 618 of the base 602. This rectangular fitting 682A prevents the drain plug assembly 680 from rotating relative to the base 602. Then, the outer pipe 694 can be screwed onto the main pipe 682. Next, the external threaded connection 684 of the main pipe 682 can engage with the internal threaded connection 698 on the outer pipe 694. Then, ratchet key 683 and ratchet teeth 697 can engage and ratchet-connect the main tube 682 and the outer tube 694 together. The outer tube 694 may include a flat-head structure 699 to allow a tool to screw the outer tube 694 into the main tube 682. The flat-head structure 699 can be any polygonal shape with one or more flat sides, such as a square, pentagon, hexagon, or other polygonal shape. The flat-head structure 699 may also include curved sides. The flat-head structure 699 can be any shape with one or more flat sides. The outer tube 694 may have a bottom protrusion feature of a specific length that prevents threaded connection between the main tube 682 and the outer tube 694 and abuts against the inner wall / face 618 of the base 602. The bottom protrusion feature sets the distance between the inner wall 618 and the outer wall 619 of the base 602.

[0125] The ratchet feature of the drain plug assembly 680 may consist of ratchet teeth 697 on the outer tube 694 and one or more ratchet keys 683 (or pawls) on the main tube 682, the ratchet keys 683 engaging the ratchet teeth 697. As the outer tube 694 is screwed onto the main tube 682, the ratchet keys 683 of the main tube 682 engage with the ratchet teeth 697 on the outer tube 694. The engagement of the ratchet keys 683 and the ratchet teeth 697 allows the main tube 682 to rotate continuously in only one direction (the closed direction), while preventing movement in the opposite direction (the open direction). The ratchet teeth 697 may be uniform but asymmetrical, each tooth having a moderate slope on one edge and a steeper slope on the other edge. When the ratchet teeth 697 move in an unrestricted (i.e., closed) direction, the ratchet key 683 easily slides upward and over the gently sloping edge of the ratchet teeth 697. As the ratchet key 683 passes the tip of each ratchet tooth 697, the pressure of the connection forces the ratchet key 683 (possibly accompanied by an audible "click") into the recess between the ratchet teeth 697. However, when the ratchet teeth 697 move in the opposite (open) direction, the ratchet key 683 engages against the steeply sloping edge of the first ratchet tooth 697 it encounters, thereby locking the ratchet key 683 against the ratchet tooth 697 and preventing any further movement in that direction.

[0126] When the main pipe 682 is fully screwed into the outer pipe 694, the edge 681 of the main pipe can engage the rear portion 614B, and the gasket 686 can engage the inner wall structure 618 of the base. The gasket 686 prevents liquid from escaping from the insulation container 600 between the drain plug assembly 680 and the cooler base 602. The gasket 686 also prevents foam from escaping during the assembly process.

[0127] Figures 24A-33 Another example of an insulated container 700, according to one or more aspects described herein, is shown. For Figures 24A-33 In some embodiments, similar reference numerals under the “7xx” series are used to designate features, rather than as in [the previous examples]. Figure 1A / Figure 1B / Figure 1C The “1xx” used in the embodiments, such as in Figure 3A / Figure 3B / Figure 3C The “2xx” used in the embodiments, such as in Figure 7A / Figure 7B The “4xx” used in the embodiments, or as in Figures 10A-23 The “6xx” feature is used in the embodiments. The “7xx” feature can be similar to the “1xx”, “2xx”, “4xx”, or “6xx” features. Therefore, the above has already referred to… Figure 1A / Figure 1B / Figure 1C , Figure 3A / Figure 3B / Figure 3C , Figure 7A / Figure 7B and Figures 10A-23 Certain features of the insulated container 700 described in the insulated containers 100, 200, 400, or 600 may be described in less detail, or may not be described at all. Additionally, references above... Figures 1A-23 Any features described in the insulation containers 100, 200, 400 and 600 can be used with the insulation container 700.

[0128] Figure 24A A front view of the insulated container 700 is depicted. Figure 24B and Figure 24D A side view of the insulated container 700 is depicted. Figure 24C A rear view of the insulated container 700 is depicted. Figure 24E A top view of the insulated container 700 is shown. Figure 24F A bottom perspective view of the insulated container 700 is shown. Figure 24G A front perspective view of the insulated container 700 is shown.

[0129] In one example, the insulated container 700 may include a base portion 702 and a lid 704, in some examples where the lid 704 may be non-destructively and removably coupled to the base portion 702. The base portion 702 may be an insulated structure forming an internal space for containing contents or liquid. In some examples, the base portion 702 may be cubic or substantially cubic in shape. In still other examples, the base portion 702 may be substantially cylindrical or may have a substantially rectangular cross-section. Various other shapes may be used without departing from the invention.

[0130] The base portion 702 may include a first end portion 706, the first end portion 706 having a bottom surface 708 (e.g., Figure 24F (as specifically shown in the diagram). The bottom surface 708 can be configured to support the insulated container on a surface such as a table, floor, vehicle cargo box, ship deck, etc.

[0131] The base portion 702 also includes a second end portion 710, the second end portion 710 defining an opening (in Figure 11As shown in the diagram, the opening can be used to access the interior space of the insulated container. When the insulated container 700 is in use (e.g., when the insulated container 700 is in a closed configuration), the opening can be covered by a cover 704. The base portion 702 may also include a plurality of side portions 714 attached to the bottom surface 708, the plurality of side portions 714 defining spaces for receiving contents within the insulated container 700. The side portions 714 may be arranged such that the side portions 714 extend substantially vertically from the bottom surface 708. The plurality of side portions 714 may include: a front side portion 714A; a rear side portion 714B opposite to the front side portion 714A; and two lateral side portions 714C, located between the front side portion 714A and the rear side portion 714B.

[0132] In some examples, one or more side pocket handles 790 may be arranged in one or more side portions 714 (or other areas of the base portion 702). The side pocket handles 790 may be integrally formed with the base portion 702 and are typically undercuts or slits formed in the side portions 714 of the base 702. In some examples, (such as in...) Figure 10B and Figure 10D The undercut or cutout forming the side pocket handle 790 (as shown) may include a recess that extends substantially all or most of the length of the side portion 714. This can provide a base 702 that is easy to manufacture with a one-piece handle 790. In some examples, the side pocket handle 790 may be flush with the outer surface of the base 702 to reduce the risk of breakage.

[0133] As discussed above, the insulated container 700 can be configured to contain, store, carry, or otherwise carry a certain volume of contents or possibly liquids. In some examples, the insulated container 700 can be configured to store approximately 60 liters (approximately 63.4 quarts) or 48 liters (approximately 50.7 quarts). In some examples, the insulated container 700 can be configured to store contents between twenty-two (22) quarts and twenty-eight (28) quarts. In some examples, the insulated container 700 can be configured to store approximately twenty-four (24) quarts of contents. In other examples, the insulated container 700 can be configured to store at least twenty-two (22) quarts of contents, or the insulated container can be configured to store at least twenty-eight (28) quarts of contents, etc. In yet another example, the insulated container 700 may be configured to store approximately sixteen (16) quarts of contents, twenty-four (24) quarts of contents, thirty-six (36) to thirty-eight (38) quarts of contents, or forty-eight (48) to fifty-eight (58) quarts of contents. In still another example, the insulated container 700 may be configured to store contents between approximately fourteen (14) quarts and approximately forty-five to twenty-eight (45) quarts. Additionally or alternatively, without departing from the scope of the disclosure described herein, the insulated container 700 may be configured to store materials in a solid, liquid, or gaseous state, or a combination thereof.

[0134] In at least some examples, the insulated container 700 (and various other containers described herein) may be sized to accommodate the volume of the contents described above. For example, the insulated container 700 may be at least seventeen (17) inches high, at least sixteen (16) inches wide, and at least fourteen (14) inches deep. Additionally or alternatively, without departing from the scope of the disclosure described herein, the insulated container 700 may be configured in different sizes (i.e., height, width, and depth).

[0135] As previously discussed, the insulated container 700 includes a cover 704. In some examples, the cover 704 may be press-fitted to the base 702 for a closed construction. Additionally or alternatively, other securing systems or devices may be used to secure the cover 704 to the base. Figure 24A and Figure 24G As shown, the insulated container 700 may include a latching device 720 and a retainer on a base 702 at the front of the container to secure the lid 704 in a closed position. In some examples, the lid 704 may be configured to be held secured or locked in a closed position using the latching device 720. The latching device 720 may be various types of latches, including latches having a latch portion and a retainer portion on the base 702, and various other types of latches. The insulated container 700 may include the features described above and... Figure 1A , Figure 1B , Figure 3A ,Figure 4A , Figure 5A , Figure 5C , Figure 6A , Figure 6B and Figure 6C Any latching devices and retainers specifically shown in the diagram.

[0136] In such Figure 24G In other configurations shown, the insulated container 700 may include a lid 704 and a base 702, the lid 704 and base 702 forming at least one corner lifting flange 792 to facilitate easy gripping of the lid for opening. In other examples, the insulated container 700 may include multiple corner lifting flanges 792. In some examples, the lifting flange 792 may be formed by an integrally formed portion of the corner of the lid 704 and an integrally formed portion of the front corner at the top of the base 702. In still other configurations, the insulated container 700 may include a front lifting flange 791, the front lifting flange 791 being integrally formed in the base 702. The front lifting flange 791 may be integrally formed at the top of the base 702. The lifting flange 791 may be configured to provide an easily accessible area to the insulated container 700 to allow an individual to grip the lid 704 for easy opening (i.e., one-handed operation).

[0137] In some examples, the cover 704 may be hinged such that it is removably or permanently attached to the base 702 at the hinge and can rotate about the hinge. The hinge may be one of various types of hinges, including continuous piano hinges, double hinges, ball joint hinges, movable hinges, etc. The hinge may allow the cover 704 to be opened and rotated away from the base portion 702 to allow (e.g., via an opening) access to the interior space defined by the base portion 702. That is, the hinge may facilitate the rotation of the cover 704 from a closed configuration of the insulated container 700 (e.g., when the cover 704 is in place covering the interior space formed by the base 702) to an open configuration (e.g., when the cover 704 does not cover the interior space formed by the base 702), and vice versa. In some examples, the insulated container 700 is configured with at least one hinge. In another example, the insulated container is configured with multiple hinges. In other configurations, the hinge comprises a first part and a second part, the first part being integrally formed in the cover 704 and the second part being integrally formed in the base 702.

[0138] In the examples described herein, the base 702 and the cover 704 may include an outer surface or housing that surrounds and encloses the insulating portion, such as Figure 1C and Figure 5AAs shown and described. The housing is typically formed of various materials, such as one or more metals, alloys, polymers, ceramics, or fiber-reinforced materials. In some examples, the housing may be formed of a plastic material, such as thermoplastic olefin elastomer (TPO), polypropylene with a rubberizing agent, or polyethylene, which is molded to form both the base 702 and the cap 704 portions. Thermoplastic olefin elastomer (TPO) consists of polypropylene, polyethylene, or other polyolefins as hard segments and a rubber component, such as ethylene propylene rubber (EPM) or ethylene propylene diene monomer (EPDM), as soft segments. In some examples, the insulating portion is formed of an insulating material exhibiting low thermal conductivity. For example, the insulating portion may be formed (or filled with) a polymer foam, such as polyurethane foam. Additional or other insulating materials may be used without departing from the invention. In some examples, the base 702 and cap 704 portions are formed using an injection molding process (not shown) as understood by those skilled in the art. However, without departing from the present invention, various other types of molding or other manufacturing processes (e.g., rotational molding, stamping, casting, forging, blow molding, etc.) can be used to form the insulated container.

[0139] The base portion 702 may include a first end portion 706 having a bottom surface 708. The bottom surface 708 may be configured to support the insulated container 700 on a surface such as a table, floor, vehicle cargo box, ship deck, etc., and may include multiple legs 713, such as... Figure 24F As shown. Multiple legs 713 may include four individual legs positioned around the periphery of the bottom surface 708. In another example embodiment, the bottom surface 708 of the insulated container 700 may include one or more lateral legs, as described above and in… Figure 19 As shown in the diagram. Multiple feet 713 can be configured to provide a non-slip or slip-free surface and can be configured to keep the insulation container 700 elevated off the ground. In another example, the multiple feet 713 can be configured to reduce friction with the ground or surface, making the insulation container easier to move (i.e., the insulation container can easily slide or be easily pushed across the ground) while it is on the ground. The multiple feet 713 can be separate and parallel, thereby creating and providing an air gap between the bottom surface 708 of the insulation container and the ground. The multiple feet 713 can be constructed of rubber, foam, plastic, or other suitable materials. In another embodiment, the multiple feet 713 can be molded into the base 702 in a mold for the multiple feet 713 with an alternative surface treatment or texture. In yet another embodiment, the bottom surface 708 may include the logo or name of the company or manufacturer of the insulation container, which is embossed, integrally molded, or pressed into the housing.

[0140] In other examples, the insulated container 700 may include a handle assembly 760, such as Figure 25 , Figure 26 and Figures 27A-27C As specifically shown in the text. Figures 12A-12C A side view of the insulated container 700 is shown, which shows the handle assembly 760 in various retracted and extended configurations. Figure 13 A side view of the insulated container 700 in an inclined configuration and the handle assembly 760 in an extended configuration is shown. Figure 25 A bottom rear perspective view of the insulated container 700 is shown, with the handle assembly 760 in a retracted configuration. Figure 26 A top rear perspective view of the insulated container 700 is shown, with the handle assembly 760 in a retracted configuration. Figures 27A-27C A component diagram of the handle assembly 760 is shown. Specifically, Figure 27A A front view of the handle assembly 760 is shown. Figure 27B A rear view of the handle assembly 760 is shown, and Figure 27C A rear perspective view of the handle assembly 760 is shown.

[0141] Figure 25 , Figure 26 and Figures 27A-27C A handle assembly 760 is shown that allows a user to ergonomically manipulate the insulated container 700. The handle assembly 760 assists the end opposite the wheel 772 to leave the container's resting surface when the insulated container 700 is tilted to a rolling position. The handle assembly 760 may be a telescopic handle design with a three-stage handle / arm configuration. In the first stage, the handle assembly 760 may be in a retracted (or retracted or nested) configuration. In the second stage, the handle assembly 760 may be in a partially extended configuration. In the third stage, the handle assembly 760 may be in a fully extended configuration. The handle assembly 760 may have one or more locking mechanisms for the retracted configuration, partially extended configuration, and / or fully extended configuration.

[0142] A handle assembly 760 can be attached to the side portion 714 of the base 702, and particularly to the rear portion 714B of the base 702. The handle assembly 760 can be arranged on the same rear portion 714B, which includes the wheel assembly 770. In the extended configuration, the user can grip the handle 762 to tilt and lift the front portion 714A, transferring the weight of the insulated container 700 to the wheel 772 and allowing the user to pull the insulated container 700. The handle assembly 760 can have an extended configuration that enables the user to pull the container 700. The handle assembly 760 can also have a retracted configuration, in which the handle assembly 760 is flush with the top of the insulated container 700. When the handle assembly 760 is in the retracted configuration, the upper surface 763 of the handle 762 can be substantially parallel to the upper surface of the cover 704. When the handle assembly 760 is in the retracted configuration, the upper surface 763 of the handle 762 can also be aligned with or located below the upper surface of the cover 704.

[0143] Handle assembly 760 can be attached to rear portion 714B. Handle assembly 760 may include one or more brackets 766A, 766B that attach handle assembly 760 to rear portion 714B. Handle assembly 760 may include one, two, three, or four or more brackets to attach handle assembly 760 to rear portion 714B. One or more brackets may include a first bracket 766A (or upper bracket) and a second bracket 766B (or lower bracket), the first bracket 766A being attached to the top portion of handle assembly 760 and the second bracket 766B being attached to the lower portion of handle assembly 760. Figure 25 and Figure 26 As shown, both the first bracket 766A and the second bracket 766B can be connected to the lower arm 764C, and in particular, the lower arm 764C and the handle assembly 760 are attached to the rear portion 714B. The bracket 766 can be mounted to the mounting point on the rear portion 714B of the base 702 before the thermal insulation (foam) is filled into the base 702.

[0144] Additionally, one or more of the brackets 766A and 766B may be U-shaped brackets that are fitted around the outside of the lower arm 764C of the handle assembly 760 so that the lower arm 764C and the handle assembly 760 remain against the rear portion 714B of the insulated container 700. Figure 27A , Figure 27B and Figure 27CAs shown, the second bracket or lower bracket 766B may include a bracket housing for the lower arm 764C of the handle assembly 760, so that the lower arm 764C and the handle assembly 760 are held against the rear portion 714B of the insulated container. Without departing from embodiments of the invention, brackets 766A and 766B may be of various other shapes. Additionally, brackets 766A and 766B may be of various widths and lengths. Brackets 766A and 766B may include one or more fasteners 767 on each side of the brackets 766A and 766B, the one or more fasteners 767 connecting the brackets 766A and 766B to the rear portion 714B of the insulated container 700.

[0145] As above (specifically in) Figure 16A , Figure 16B , Figure 17A , Figure 17B and Figure 17C As described and shown in the diagram, the handle assembly 760 may include a telescopic feature. The handle assembly 760 may include an upper arm, a middle arm, and a lower arm 764C. The upper arm may be nested within the middle arm and is capable of sliding within the middle arm. Additionally, the middle arm may be nested within the lower arm 764C and is capable of sliding within the lower arm 764C. This nesting and sliding of the upper arm, middle arm, and lower arm 764C creates the telescopic feature of the handle assembly 760.

[0146] Figure 27A , Figure 27B and Figure 27C The various component views of the handle assembly 760 are shown in detail. Figure 17A The handle assembly 760 is shown in detail in the front view. The handle assembly 760 may include one or more locking mechanisms, such as an upper locking mechanism and a lower locking mechanism. The locking mechanisms may be mounted between the arms to latch and lock the handle assembly 760 in a retracted configuration and / or a fully extended configuration. Specifically, the upper locking mechanism may be mounted between the upper arm and the intermediate arm. The lower locking mechanism may be mounted between the intermediate arm and the lower arm 764C. A release button 768 may be connected to the locking mechanism and act as an actuator for the locking mechanism. The locking mechanism can be released using the release button 768 on the handle 762. The locking mechanism may include various components known and used in the art for telescopic handles, such as actuators, hinges, spring-loaded bearings, bushings, locking pins, locking holes, etc.

[0147] like Figure 25 , Figure 26 and Figures 27A-27CAs shown, the handle assembly 760 may include a handle 762. A user can grip the handle 762 to extend the handle assembly 760 into the extension configuration. The user can grip the handle 762 in the extension configuration to tilt and lift the front portion 714A, which transfers the weight of the insulation container 700 onto the wheel 772 and allows the user to pull the insulation container 700.

[0148] Handle 762 may include handle buffers (as previously detailed above and in) Figure 18 (As shown in the diagram). A handle damper may be located on each of the pull arms of the handle 762. When the insulated container 700 is tipped over / if the insulated container 700 is tipped over, the handle damper may be used to prevent wear on the handle grip 763 on the handle 762. The handle damper may include a raised portion that extends circumferentially around the handle 762 adjacent to and / or around the upper pull arm. The raised portion may extend circumferentially around the handle 762 and / or the pull arm, either partially or completely.

[0149] The handle assembly 760 can be formed from a polymer material, which can be a filled or unfilled polymer. For example, the polymer material can be PC-ABS, polyethylene, or other similar materials. Furthermore, the handle assembly 760 can be manufactured using polymer processing techniques, such as through various molding and casting techniques or other known techniques. Alternatively or optionally, the handle assembly 760 can be formed from a metallic material, such as aluminum alloy, magnesium alloy, or other metallic materials having a density of less than 3 g / cc. Alternatively, components of the insulated container 700, such as the lid, body, lid support member, and handle assembly, can include a structural foam having a low-density foam core and a higher-density polymer outer layer.

[0150] In other examples, the insulated container 700 may include a rear wheel assembly 770, such as Figure 28 , Figure 29A , Figure 29B , Figure 29C , Figure 30 and Figure 31 As specifically shown in the text. Figure 28 A bottom perspective view of the insulated container 700 is shown, which reveals the wheel assembly 770. Figure 29A and Figure 29B A view of the wheel assembly 770 and anti-rotation mount 778 for the insulated container 700 is shown, with a portion of the handle assembly 760 removed. Figure 29C A rear cross-sectional view of the shaft attachment and anti-rotation mount 778 of the wheel assembly 770 for the thermal insulation container 700 is shown. Figure 30A side perspective view of wheel recesses 773 on the base 702 of the heat-insulating container 700 is shown, wherein each wheel 772 can be fixed to the base 702.

[0151] The insulated container 700 may include a wheel assembly 770, which includes a pair of wheels 772 to assist a user in easily moving the insulated container 700. The wheel assembly 770 may include a tire 771 and wheels 772, wherein each wheel 772 can be mounted to a base 702 via an axle 774. The wheel assembly 770 may include a single axle 774 or a dual axle 774, with a single axle 774 for both wheels 772 and a dual axle 774 having an axle for each wheel 772. The tire 771 may be made of polyurethane foam with a hardness of approximately 80 Shore A and a density of 0.75 kg / L. The wheel 772 may be made of a rigid material, such as glass-filled nylon. The tire 771 may be overmolded, stretch-fitted, or grip-fitted over the wheel 772. The wheel 772 may include ribs or other gripping structures on the inner rim of the wheel 772 to aid in gripping the foam tire 771.

[0152] Each wheel assembly 770 and wheel 772 can be mounted to the base 702. More specifically, each wheel 772 can be mounted adjacent to the bottom surface 708 of the insulation container 700 to the rear portion 714B. Each wheel 772 can be secured to a wheel recess 773 on the base portion 702 and the rear portion 714B. Each wheel 772 can be secured within the recess 773 using at least one spring retaining ring and connected to at least one axle 774. Additionally, the wheel 772 and tire 771 can extend rearward beyond the handle assembly 760, thereby providing additional end protection to the handle assembly 760. Additionally, when the insulation container 700 is laid flat on the ground, the wheel 772 and tire 771 can be above the ground. The tire 771 may also include a flat tread profile for improved performance on sandy / soft terrain. The wheel 772 may also include a single-walled hub for providing a lighter weight. Additionally, the flatter and thinner tread profile of tire 771 can provide a lighter wheel.

[0153] Figure 29A and Figure 29BAn exemplary embodiment of the wheel assembly 770 is specifically illustrated, showing a wheel 772 and a shaft 774 for an insulated container 700. The wheel assembly 770 may include one or more ball bearings and spacers 777B on the shaft 774, the spacers 777B defining the distance between the bearings. The spacers 777B may be made of a rigid polypropylene material and may be used to position the wheel 772. The wheel 772, spacers 777B, and wheel eyelets 776 may be held along the axis of the shaft 774 by spring retaining rings along the ends of the shaft 774. The spring retaining rings may be radially fitted around the ends of the shaft 774 to hold the shaft 774 through the wheel 772 and retain the shaft 774 within the base 702.

[0154] Additionally, the wheel assembly 770 may include wheel buckle 776, as described above. Figure 20A and Figure 20B As detailed and illustrated herein, a wheel eyelet 776 may be located between the wheel recess 773 and the spacer 777B. The wheel eyelet 776 may also be positioned around the shaft 774 and may provide a seal between the wheel recess 773 and the inner portion of the base 702. The wheel eyelet 776 may be a rubber / non-rigid material (such as EPDM rubber). The wheel eyelet 776 may be used to prevent water or other materials from entering the insulation center of the base 702. The wheel eyelet 776 may be a bushing or eyelet to absorb vibrations or forces impacting the wheel 772 and to absorb vibrations and cushion the shaft 774. By absorbing vibrations, the wheel eyelet 776 may allow the shaft 774 to rotate when high forces are applied to the wheel 772. For example, during a drop test simulating the insulated container 700 being dropped and the insulated container 700 being loaded with approximately 75 pounds, the wheel assembly 770 will not be damaged due to the wheel eyelet 776. The full force from the drop can be concentrated on the axle 774, rather than on the wheel 772. The force from the drop can be absorbed and / or dissipated by the wheel eyelets 776, thereby reducing and preventing strong vibrations from reaching the base 702, axle 774, axle support 778, and other critical components. Drop testing may include dropping the insulated container 700 from approximately one meter above the ground under cold, hot, and room temperature conditions. The insulated container 700 may be dropped in multiple orientations, including being dropped on its back with impact force applied to both wheels 772, and being dropped on the corner of a wheel with force applied to a single wheel 772.

[0155] Figure 29A , Figure 29B and Figure 29C Specifically, an exemplary embodiment of a shaft support 778 for preventing the shaft 774 from rotating and dislodging is shown. Figure 29A and Figure 29BA shaft bracket 778 is shown, in which the handle assembly 760 is concealed. The shaft bracket 778 may be an anti-rotation mount abutting against the base 702. Each shaft 774 may have at least one shaft bracket 778. Additionally, each shaft 774 may have multiple shaft brackets 778, such as two, three, or four shaft brackets 778. One or more shaft brackets 778 may be covered from view by the handle assembly 760. The shaft bracket 778 may be attached to the shaft 774 with a fastener 779. The shaft 774 may include a flat section 774A having a fastener attachment point 779A. The flat section 774A of the shaft 774 may be compressed and permanently mates with the flat section 778A of the shaft bracket 778. The shaft bracket 778 may include an additional flat and mating feature 778B that contacts and holds the shaft bracket 778 against the base 702. These flat sections 778A prevent the shaft 774 from rotating about the base 702 by keeping the shaft 774 stationary and in a permanent position in the base 702.

[0156] Figure 30 The wheel recess 773 of the base 702 of the heat-insulating container 700 is shown. (As shown) Figure 30 As shown, the wheel recess 773 may include formed radial ribs 773A extending from the shaft bore / opening 774A. The radial ribs 773A can provide strength within the base 702 for retaining the shaft 774 and the wheel assembly 770. Any number of radial ribs 773 can be used to help provide strength within the base 702 and the insulation container 700.

[0157] In other examples, the insulation container 700 may include a drain plug assembly 780, such as Figure 24C , Figure 25 , Figure 31 , Figure 32 and Figure 33 As specifically shown in the text. Figure 31 A side cross-sectional view of a drain plug assembly 780 for an insulated container 700 is shown. Figure 32 An exploded view of the drain plug assembly 780 for the insulated container 700 is shown. Figure 33 An additional exploded view of a drain plug assembly 780 with a drain plug 787 for use in an insulated container 700 is shown.

[0158] like Figures 31-33As shown, the drain plug assembly 780 may include a main pipe 782, an outer pipe 794, a washer 786, and a drain plug 787. A user can use the drain plug 787 to screw into or out of the drain plug assembly 780 to drain the insulation container 700. The drain plug assembly 780 may be positioned and mounted within a through-hole in the wall of the base portion 702. In the illustrated embodiment, the drain plug assembly 780 may be positioned adjacent to the bottom surface 708 of the insulation container 700 on the rear portion 714B. The drain plug assembly 780 may be mounted and positioned within a drain plug insert 709, which provides protection for the drain plug assembly 780. The drain plug assembly 780 may include a ratchet feature, wherein the main pipe 782 (or inner pipe) is keyed so that the main pipe 782 cannot be rotated / opened when it is screwed into the outer pipe 794.

[0159] The main pipe 782 may include a drain through-hole portion 785 having one or more ratchet keys 783 at a first end and a main pipe edge 781 at the opposite end. The drain through-hole portion 785 may include an internal thread 785A that engages with an external thread 788 on a drain plug 787. The main pipe 782 may also have an externally threaded connection 784 located between the main pipe edge 781 and the ratchet keys 783. The main pipe 782 may also include a washer 786. The washer 786 may provide compression between the main pipe 782 and the inner wall 781 of the base 702. The washer 786 may include a radial feature 786A that helps to position the washer 786 against the main pipe edge 781 and the inner wall 718 of the base 702. The washer 786 may be a separate component, or the washer 786 may be molded into the main pipe 782. The gasket 786 can be a softer material, such as silicone, while the main tube 782 is a rigid material. The gasket 786 can, for example, have a hardness of 40 Shore A. The outer tube 794 can include an internally threaded connection 798. The outer tube 794 can also include an outer tube edge 795 and ratchet teeth 797 on the same end. The ratchet teeth 797 can be located on an inner portion of the outer tube 794. The outer tube 794 can also include a sealing ring 794A, which is disposed against the outer tube edge 795 of the outer tube 794. The sealing ring 794A can be seated between the outer tube edge 795 and the rear portion 714B and the base outer wall structure 719. The sealing ring 794A can also provide a seal to prevent foam from escaping during assembly. The sealing ring 794A can be a single ring concentric about the axis of the outer tube 794. The sealing ring 794A can also be multiple rings or non-circular.

[0160] like Figure 31As shown, the main pipe 782 and the outer pipe 794 can be joined to form and produce a drain plug assembly 780. The main pipe 782 and the outer pipe 794 can pass through the rear portion 714B, the inner wall structure 718 of the base, and the outer wall structure 719 of the base. The main pipe 782 and the outer pipe 794 can be engaged with each other to produce the drain plug assembly 780 of the insulated container 700. The main pipe 782 can be installed first using a rectangular feature having a flat portion 782A on the main pipe 782, which mates with a rectangular opening in the rear portion 714B and the inner wall 718 of the base 702. This rectangular fitting prevents the drain plug assembly 780 from rotating relative to the base 702. Then, the outer pipe 794 can be screwed onto the main pipe 782. Next, the external threaded connection 784 of the main pipe 782 can engage with the internal threaded connection 798 on the outer pipe 794. Then, the ratchet key 783 and ratchet teeth 797 can engage and ratchet-connect the main tube 782 and the outer tube 794 together. The outer tube 794 may include a flat-head structure 799 to allow a tool to screw the outer tube 794 into the main tube 782. The flat-head structure 799 can be any polygonal shape with one or more flat sides, such as a square, pentagon, hexagon, or other polygonal shape. The flat-head structure 799 may also include curved sides. The flat-head structure 799 can be any shape with one or more flat sides. The outer tube 794 may have a bottom protrusion feature of a specific length that prevents threaded connection between the main tube 782 and the outer tube 794 and abuts against the inner wall / face 718 of the base 702. The bottom protrusion feature sets the distance between the inner wall 718 and the outer wall 719 of the base 702.

[0161] The ratchet feature of the drain plug assembly 780 may consist of ratchet teeth 797 on the outer tube 794 and one or more ratchet keys 783 (or pawls) on the main tube 782, the ratchet keys 783 engaging the ratchet teeth 797. As the outer tube 794 is screwed onto the main tube 782, the ratchet keys 783 of the main tube 782 engage with the ratchet teeth 797 on the outer tube 794. The engagement of the ratchet keys 783 and the ratchet teeth 797 allows the main tube 782 to rotate continuously in only one direction (the closed direction), while preventing movement in the opposite direction (the open direction). The ratchet teeth 797 may be uniform but asymmetrical, each tooth having a moderate slope on one edge and a steeper slope on the other edge. When the ratchet teeth 797 move in an unrestricted (i.e., closed) direction, the ratchet key 783 easily slides upward and over the gently sloping edge of the ratchet teeth 797. As the ratchet key 783 passes the tip of each ratchet tooth 797, the pressure of the connection forces the ratchet key 783 (possibly accompanied by an audible "click") into the recess between the ratchet teeth 797. However, when the ratchet teeth 797 move in the opposite (open) direction, the ratchet key 783 engages against the steeply sloping edge of the first ratchet tooth 797 it encounters, thereby locking the ratchet key 783 against the ratchet tooth 797 and preventing any further movement in that direction.

[0162] When the main pipe 782 is fully screwed into the outer pipe 794, the edge 781 of the main pipe can engage the rear portion 714B, and the gasket 786 can engage the inner wall structure 718 of the base. The gasket 786 prevents liquid from escaping from the insulation container 700 between the drain plug assembly 780 and the cooler base 702. The gasket 786 also prevents foam from escaping during the assembly process.

[0163] like Figure 33 As shown, the drain plug 787 may include an external thread 788. When the drain plug 787 is screwed into the drain plug assembly 780 and the main pipe 782, the external thread 788 on the drain plug 787 can engage with the internal thread 785A of the drain through-hole portion 785 of the drain plug assembly 780. Additionally, a drain plug cap 789 and a washer may be included in the top portion of the drain plug 787. The drain plug cap 789 may include features to assist a user in tightening and loosening the drain plug 787 from the drain plug assembly 780. Additionally, the drain plug 787 may include various washers to ensure a watertight seal when the drain plug 787 is screwed onto the main pipe 782 and the drain plug assembly 780.

[0164] Figures 34A-34C and Figures 35A-35E Another example of an insulated container 800 is shown, according to one or more aspects described herein. For Figures 34A-34C and Figures 35A-35EIn some embodiments, similar reference numerals under the "8xx" series are used to designate features, rather than as in [other examples]. Figure 1A / Figure 1B / Figure 1C The “1xx” used in the embodiments, such as in Figure 3A / Figure 3B / Figure 3C The “2xx” used in the embodiments, such as in Figure 7A / Figure 7B The “4xx” used in the embodiments, such as in Figures 10A-23 The “6xx” used in the embodiments, or as in Figures 24A-33 The "7xx" feature is used in the embodiments. The "7xx" feature can be similar to the "1xx", "2xx", "4xx", or "6xx" features. Therefore, the above has already referred to... Figure 1A / Figure 1B / Figure 1C , Figure 3A / Figure 3B / Figure 3C , Figure 7A / Figure 7B and Figures 10A-33 Certain features of the insulated container 700 described in the description of insulated containers 100, 200, 400, 600, or 700 may be described in less detail, or may not be described at all. Additionally, the above references... Figures 1A-33 Any features described in the insulation containers 100, 200, 400, 600 and 700 can be used with the insulation container 800.

[0165] like Figures 34A-34C As shown, the insulated container 800 may include a corner locking bracket 830. The corner locking bracket 830 may be mounted and / or attached to the insulated container 800 to lock the insulated container 800 into a closed / locked configuration. In one embodiment, the corner locking bracket 830 may be a corner bracket kit. In one example, the corner locking bracket 830 may include a container bracket 832, a lid bracket 834, a plurality of fasteners 836, and a lock 838. The container bracket 832 and the lid bracket 834 may include a lock hole 833 and one or more fastener holes 835. Figure 34B As shown, container bracket 832 and lid bracket 834 can be attached to the corner of insulated container 800. Container bracket 832 and lid bracket 834 can be attached to insulated container 800 using one or more fasteners 836 passing through one or more fastener holes 835. Figure 34BAs shown, a container support 832 can be attached to a corner of the base 802 along the top side portion 802B of the base 802, and a cover support 834 can be attached to a corner of the bottom side portion 804B of the cover 804. When the cover 804 is in a closed and secured configuration, the container support 832 and the cover support 834 mate the locking holes 833 from the container support 832 and the cover support 834, thereby allowing a lock 838 to be inserted into the locking holes 833 of both. The corner locking support 830 may include a metal washer formed into the corner locking support to reinforce the locking holes 833. Additionally, one or more screw bosses may be concealed in the base 802 and / or the cover 804. The one or more screw bosses may include recesses for fastener / screw alignment, wherein one or more of the plurality of fasteners 836 may penetrate the surface of the base 802 and / or the cover 804 before the fasteners 836 can engage with the screw bosses.

[0166] like Figures 35A-35E As shown, accessories 840, such as trays or baskets 840, or container separators 844, may be positioned or stored at the bottom of the interior space of the insulated container 800, and / or may be configured to rest on top of the interior space. In some examples, one or more container separators 844 may be located within the interior space of the insulated container 800 to separate the contents within the insulated container 800. In some examples, the tray or basket 840 may include a lip 842 surrounding the periphery of the tray, allowing the tray 840 to hang from the edge of the opening 812 while remaining within the interior space of the insulated container 800. This configuration allows the lid 804 to be configured in a closed and secured position, thereby sealing the interior space while the tray or basket 840 and / or container separators 844 are properly secured inside / within the insulated container 800.

[0167] In other example embodiments, the insulated container may be an injection-molded container. For example, portions or components of the insulated container may be formed in multiple parts using exemplary welding processes, such as a lid being formed in two parts. Exemplary welding processes may use adhesives, ultrasonic welding techniques, or electromagnetic bonding (such as...). This can be used in conjunction with parts or components of the insulated containers disclosed herein. For example, as described in U.S. Patent No. 7,984,738 (the disclosure of which is incorporated herein by reference), the electromagnetic welding element preform can be a structure composed of plastic and magnetic particles. When an energized high-frequency induction coil is placed near the joint, the particles act as acceptors of electromagnetic radiation, and the resulting induced eddy currents sufficiently heat the element to melt the preform and the adjacent plastic, thereby melting the joint. The metal particles remain within the molten plastic component.

[0168] In one example, an airtight seal can be formed between the two parts forming the lid and the two parts forming the lower shell of the insulated container. Exemplary welding processes can provide excellent plastic welding for demanding applications. For example, electromagnetic adhesion (such as...) The welding process uses high-frequency energy coupled to the electromagnetic base material to precisely transfer heat to the bonding line, providing excellent weldability to virtually all thermoplastic materials. An airtight seal can be formed completely around the perimeter of the insulation container where the weld is located, ensuring that moisture and other contaminants cannot degrade the foam and the interior of the insulation container.

[0169] Figures 36A-36C Exemplary electromagnetic adhesions (such as those described herein) are illustrated according to one or more aspects. Welding process 900, an exemplary electromagnetic adhesive welding process 900, can be used with insulated containers. Figure 36A As shown, the first component 910 (which may be referred to as a tongue) can be soldered to the second component 920 (which may also be referred to as a groove) using an electromagnetic base material 930 and a high-frequency energy source 932, such as a radio frequency (RF) coil. The parameters of the electromagnetic bonding are typically standard and can be slightly adjusted to meet the needs of specific designs and / or materials, similar to the process settings on an injection molding machine.

[0170] In one example, the first component 910 may be in the form of a tongue, and the second component 920 may be in the form of a groove to form a joint between the tongue and the groove. The first component 910 may be a cap, and the second component 920 may be a base / body. The cap and the base / body may have the same geometry for both the tongue and the groove. The joint on the cap and the base of the insulated container may have the same tongue and groove. Additional ribs or geometry may be present on the side of the tongue, guiding the tongue within the groove, which helps maintain the component geometry and the electromagnetic base material 930, thereby preventing leakage of the electromagnetic base material 930 at the joint and / or preventing changes in the electromagnetic base material 930 on the surface of the surface treatment material. The electromagnetic base material 930 may be placed within the joint between the first component 910 and the second component 920. The first component 910 and the second component 920 may be placed together and housed within a fixture containing a high-frequency energy source 932, which may conform to the weld line geometry.

[0171] Figure 36BAn RF coil 932 is shown, which emits precise and focused high-frequency energy (RF energy) towards the welding position between the first component 910 and the second component 920 and the electromagnetic base material 930. During the bonding of the first component 910 and the second component 920, the activated RF coil 932 heats and melts the electromagnetic base material 930, thereby melting the adjacent surfaces. The energy is only consumed during the actual heating cycle, which is typically between 1 second and 30 seconds.

[0172] Figure 36C The final weld of the electromagnetic base material 931 formed and welded between the first component 910 and the second component 920 is shown. After joining the first component 910 and the second component 920, the electromagnetic base material 930 may have filled the designed gap of the joint. An exemplary welding process may involve melting the first component 910 and the second component 920 to form a polymer-to-polymer weld. Additionally, although the first component 910 and the second component 920 may be in the form of tongue-shaped and grooved joints, other joints and connections are contemplated, such as dovetails, butt joints, pockets, mortises, half-lap joints, boxes, half-grooves, dovetails, etc.

[0173] The above reference Figures 1A-36C Any feature described in the insulated containers 100, 200, 400, 600, 700, or 800 may be used in conjunction with any of the other insulated containers 100, 200, 400, 600, 700, and 800, even if not specifically described using that insulated container. Therefore, certain features of any of the insulated containers 100, 200, 400, 600, 700, or 800 described above with reference to those insulated containers 100, 200, 400, 600, 700, or 800 may be described in less detail, or may be described without any or all of the other insulated containers 100, 200, 400, 600, 700, and 800.

[0174] Additionally or alternatively, various other venting or pressure regulating arrangements may be used without departing from the invention. For example, a portion of the base may comprise a material that is permeable to air but not to water or other liquids. This mesh material may allow venting without allowing liquids contained within the insulating container to overflow.

[0175] The insulated containers described herein include various features that ensure ease and efficiency in their manufacture, while also providing durability and abrasion resistance. The insulated containers and various integrally molded features, such as side bag handles, pressure regulating mechanisms or devices, latching devices, etc., can be advantageous in enhancing durability and abrasion resistance.

[0176] This disclosure has been made above and with reference to various examples in the accompanying drawings. However, the purpose of this disclosure is to provide examples of various features and concepts related to this disclosure, and not to limit the scope of the invention. Those skilled in the art will recognize that many variations and modifications can be made to the examples described above without departing from the scope of this disclosure.
