It is also envisioned that the various disclosures described herein may be combined in any way so as to allow for various permutations of the combined elements.

[0015] Various magnetic closure mechanisms are described in the following disclosures. These magnetic closure mechanisms may be configured to form a seal that is partially or completely waterproof and / or airtight and / or, when sealed, partially or completely prevents dust and other materials from passing through the magnetic closure mechanism. Without departing from the scope of these disclosures, it is assumed that the magnetic closure mechanisms include gaskets and seals in addition to the described magnetic elements.

[0016] Any container described herein is intended to be partially or completely waterproof, airtight, and / or sealed to substantially or completely prevent dust or other substances from entering and / or leaking out of the container. For example, the containers described herein may have a partially or completely waterproof outer shell / wall and a closing mechanism.

[0017] Figure 1 shows a front view of an exemplary container 100. Container 100 can be configured to keep its contents cold or hot for extended periods. Container 100 may include elements similar to those of the container described in U.S. Patent No. 1,0143282, filed on March 6, 2017, and issued on December 4, 2018. All the contents of that patent are incorporated herein by reference in their entirety for any and all non-limiting purposes. Figure 2 shows a rear view of container 100, and Figures 3-4 show side views of container 100. Container 100 generally comprises an outer shell 102 defining a front portion 130, a rear portion 160, a left side portion 180, a right side portion 190, and a bottom portion 140. In one example, the front portion 130, the rear portion 160, and the side portions 180, 190 can be collectively referred to as the side walls of container 100. The container 100 may also have an opening 110 at the top of the container and a flap portion 140 extending over the opening from one or both sides of the front portion 130 or the rear portion 160. Thus, the flap portion 140 is constructed to extend over the top of the outer shell 102 and beyond the opening 110. The opening 110 is constructed to provide a resealable point for entering the storage compartment 120 of the container 100. The storage compartment is shown in more detail in Figure 5. In one example, the opening 110 may include a front side 112 connected to the front portion 130 and a rear side 114 connected to the rear portion 160. The opening 110 can be resealably sealed by a closing mechanism 200. Here, the container 100 may have an open state that allows access to the storage compartment 120 and a closed state that prevents access to the storage compartment 120. The opening 110 may also include a pull tab 116, which is designed to be grasped by hand to pull the front side 112 and the back side 114 apart from each other in order to release the seal of the opening 110. In some examples, the container 100 may have two pull tabs 116, with the pull tabs 116 positioned on each side of the opening 110.

[0018] As shown in Figures 5, 6A, and 6B, the closing mechanism 200 may comprise a first closing element 300 and a second closing element 310. Optionally, the closing mechanism 200 may also comprise a first curved member 230 and a second curved member 240. The closing mechanism 200 can form a waterproof and / or airtight seal. The closing elements 300, 310 may be resealable closing elements such as magnetic strips. In some examples, the closing mechanism 200 may comprise a first magnetic strip 300, a second magnetic strip 310, a first curved member 230, and a second curved member 240. The first magnetic strip 300 may extend along the inner surface of the front portion 130 on the front side 112 of the opening 110 and be connected to its inner surface, and the second magnetic strip 310 may extend along the inner surface of the rear portion 160 on the rear side 114 of the opening 110 and be connected to its inner surface. The first magnetic strip 300 can be magnetically attracted to the second magnetic strip 310, thereby resealing the opening 110 and keeping the container 100 closed. The first curved member 230 can extend along the inner surface of the first portion 130 and be positioned at a predetermined distance below the first magnetic strip 300. Similarly, the second curved member 240 can extend along the inner surface of the rear portion 160 and be positioned at a predetermined distance below the second magnetic strip 310. In some examples, the first curved member 230 can be substantially aligned with the upper edge 247 of the second curved member 240. The first curved member 230 can be fixed within the front receiving portion 250 of the first portion 130 of the container 100, and the second curved member 240 can be fixed within the rear receiving portion 260 of the rear portion 160 of the container 100. When closed, the first and second magnetic strips 300, 310 can be substantially aligned with each other, and the first and second curved members 230, 240 can be substantially aligned. Alternatively, the curved members 230, 240 can extend along the outer surfaces of the front portion 130 and the rear portion 160, respectively, and connect to their outer surfaces. As an example, the receiving portions 250, 260 can be positioned along the outer surface of the outer shell 102.Once the user moves the container 100 to an open position by separating the first and second magnetic strips 300, 310, the first and second curved members 230, 240 can prevent the container 100 from closing and perform the function of holding (maintaining) the container 100 in an open position. If necessary, the closing mechanism 200 may have only one curved member 230 or 240 located on only one side of the closure (for example, one curved member 230 along the front portion 130 of the container 100, or one curved member 240 along the back portion 160 of the container 100). In some examples, the container 100 may include an auxiliary closure such as a zipper or other mechanical closure. If a zipper is used, the zipper may be a waterproof zipper.

[0019] The first and second curved members 230 and 240 can apply a spring force in the opposite direction to the magnetic force acting between the first magnetic strip 300 and the second magnetic strip 310 to prevent the opening 110 of the container 100 from accidentally closing. These opposing forces also allow the opening 110 to move in a controlled manner from the open state to the closed state. By allowing the closing mechanism 200 to move in a slow controlled manner from the open state to the closed state, it is possible to prevent the closing mechanism 200 from closing too quickly and injuring the user, thereby providing a safe and effective sealing mechanism.

[0020] More specifically, the curved members 230 and 240 can provide a spring force acting in the opposite direction to the magnetic force of the magnetic strips 300 and 310. The curved members 230 and 240 can be formed to have a curved profile with a concave contour facing the opening 110 of the container 100. The first curved member 230 may have a first end 232, a second end 234, and a curved member body 236 extending between the first end 232 and the second end. Similarly, the second curved member 240 may have a first end, a second end, and a curved member body extending between the first end and the second end. In addition, the curved members 230 and 240 can be fixedly attached to the front portion 130 and the rear portion 160 at their respective mounting points 235, which can be located at or near the center of each curved member 230 and 240. Each end 232, 234 can move and slide freely within their respective receiving portions 250, 260, allowing the curved members 230, 240 to deform and bend during the opening and closing processes. When the opening 110 is open, the curved members 230, 240 are in an undeformed or substantially undeformed state (i.e., the curved members 230, 240 have their original curved profile shape or a first curved form). When a user applies force to move the opening 110 toward the closed state, the magnetic force between the magnetic strips 300, 310 begins to attract the front side 112 toward the rear side 114 of the opening 110, while the curved members 230, 240 begin to apply spring forces that pull the front side 112 and the rear side 114 away from each other. These opposing forces cause the opening 110 to close in a slow, controlled manner. The curved members 230, 240 may be similar to those described herein by reference for any and all non-limiting purposes, U.S. Patent Application No. 17 / 673688, filed February 16, 2022.

[0021] Figures 5, 6A, and 6B schematically show cross-sectional side views of the insulated container 100. As shown in Figures 5, 6A, and 6B, magnetic strips 300, 310 can be provided in the opening 110, and curved members 230, 240 can be spaced apart below the respective magnetic strips 300, 310. In the illustrated example, the inner liner 122 forms a chamber, container, or storage compartment 120 for containing and storing contents. The insulated container 100 may comprise the inner liner 122, an insulating layer 124, and an outer shell 102. The insulating layer 124 can be provided between the inner liner 122 and the outer shell 102 and can be formed as a foamed insulating material that helps maintain the internal temperature of the storage compartment 120 for storing contents that are to be kept cold or warm. Furthermore, the first curved member 230 can be positioned between the inner liner 122 and the outer shell 102. As shown in Figures 5, 6A, and 6B, the rear curved member 240 can be positioned between the insulation layer 124 and the outer shell 102. Furthermore, the front and rear receiving portions 250 and 260 can be formed to secure the curved members 230 and 240 on all sides so that they are sealed within the receiving portions 250 and 260, respectively. The curved members 230 and 240 can be slid into the respective receiving portions 250 and 260 before the ends of the receiving portions 250 and 260 are sealed. The receiving portions 250 and 260 can be formed from the same material as the inner liner 122, or a similar material known to those skilled in the art, using welding, bonding, taping, or other processes to connect the receiving portions 250 and 260 to the container 100. As previously mentioned, the central portions of the curved members 230 and 240 can be fixedly attached to the respective front portion 130 and back portion 160 so that the ends of each curved member 230 and 240 can move freely. Alternatively, or as needed, the curved members 230 and 240 may not be fixedly attached at any or more points, and may move or slide freely within their respective receiving portions 250 and 260.Furthermore, the curved members 230 and 240 can be partially or completely housed within their respective receiving portions 250 and 260, and in some examples, they can be fixed and attached at multiple locations, such as near the center and near each end.

[0022] The insulation layer 124 can be provided between the inner liner 122 and the outer shell 102, and may not be attached to either the inner liner 122 or the outer shell 102 so as to float between them. In one example, the inner liner 122 and the outer shell 102 can be connected at the top 108 of the insulated container 100 so that the insulation layer 124 floats freely within a pocket formed by the inner liner 122 and the outer shell 102. The inner layer or inner liner 122 can be formed from a first inner liner sidewall portion 122A and a bottom inner liner portion 122B. The first inner liner sidewall portion 122A and the bottom inner liner portion 122B can be fixed to each other, for example, by welding or other means, to form a storage compartment 120. In some examples, the storage compartment 120 may be a “dry bag” or a container for storing contents. In one example, after the first inner liner sidewall portion 122A and the bottom inner liner portion 122B are fixed and connected to each other, tape such as TPU tape can be placed over the seam to help connect and seal the parts of the storage compartment 120. The tape can also be used to seal the seam formed between the first inner liner sidewall portion 122A and the bottom inner liner portion 122B in order to provide an additional barrier to liquid that prevents liquid from flowing into or out of the storage compartment 120. Thus, the inner liner 122 can maintain liquid contents within the storage compartment 120 of the insulated container 100 or prevent liquid contents from entering the storage compartment 120 of the insulated container 100. However, the inner liner 122 may be formed as a single, integrated one-piece structure that can be fixed within the outer shell 102. The liner material can be made from thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), thermoplastic copolyester elastomer (TPC), or other materials known to those skilled in the art. If necessary, the inner liner may be treated with or composed of a material having antimicrobial or other functional additives.

[0023] In one example, the closure mechanism 200 used to seal the opening 110 is substantially waterproof or water-resistant and can prevent or reduce the ingress and / or leakage of liquid into the insulated container 100. Furthermore, the flap portion 140 may be folded to further seal the opening 110, as shown in Figures 7A-7B. The flap portion 140 can be folded between the magnetic strips 300, 310 and the curved members 230, 240. The flap portion 140 can be further secured in the folded position using magnets, buckles, straps, hook-and-loop fasteners, zippers, and / or other known fastening means.

[0024] Returning to Figures 1 and 2, the insulated container 100 may be equipped with various handles, straps and loops, and webs (e.g., 132, 134, 136) for transporting, holding, or securing the insulated container 100. In this regard, the outer shell 102 may also be equipped with several reinforcing areas or patches, e.g., 107A-107C, designed to help structurally support optional handles and straps (e.g., 132, 134, 136, 162). These reinforcing areas or patches may be provided on the inner or outer surface of the outer shell 102. The handles and straps (e.g., 132, 134, 136, 162) and other attachments may be sewn, glued, welded, or riveted to the main structure of the insulated container 100 using any other attachment method or combination of methods.

[0025] The insulated container 100 may be equipped with a number of carry handles 136 connected to the front portion 130 and the rear portion 160 of the insulated container 100. In one example, a shoulder strap can be attached to the mounting rings 138A and 138B. The insulated container 100 may further be equipped with side handles 132 to facilitate the transport of the insulated container 100. In addition, webbing formed as loops 134 can be sewn to the straps of the handles 136 or attached in other ways. Items (e.g., carabiners, dry bags) can be attached to the insulated container 100 using the loops 134. In one example, the carry handles 136, side handles 132, and loops 134 can be constructed from nylon webbing. Other materials include, in particular, polypropylene, neoprene, polyester, TPU, TPC, TPE, Dyneema®, Kevlar®, cotton fabric, leather, plastic, rubber, or rope.

[0026] In one example, rings 138A to 138D may be D-rings made of polyacetal (POM). Mounting rings 138A to 138D can be made of one or more polymers, metals, ceramics, glass, alloys, or combinations thereof. In certain specific examples, mounting rings 138A to 138D can be made of nylon, polypropylene, neoprene, polyester, "Dyneema," and "Kevlar," cotton fabric, leather, plastic, rubber, or rope, or mixtures thereof. In some examples, mounting rings 138A to 138D may contain a certain amount of recycled material. Mounting rings 138A to 138D may have shapes, sizes, and structures other than the illustrated "D" shape. Examples include circular, square, rectangular, triangular, or rings with multiple mounting points.

[0027] Figure 1 further illustrates the bottom 104 and the bottom support ridge 106. The bottom support ridge 106 can provide structural integrity and support to the insulated container 100 (also referred to as the insulated device 100) when the insulated container 100 is placed on a surface.

[0028] The flap portion 140 may have a front side 142 and a rear side 144. Furthermore, in one embodiment, the flap portion 140 may be configured so that the upper flap portion 146 folds over the bottom flap portion 148. When folded, the upper flap portion 146 may be detachably connected to the bottom flap portion 148 by an auxiliary closing mechanism. In one example, both the upper flap portion 146 and the bottom flap portion 148 may have magnetic elements (e.g., permanent magnets and magnetic materials) embedded in the container 100 along the length L of the opening 110. In one example, a single magnetic strip may be embedded in one or more of the upper flap portion 146 and the bottom flap portion 148 and extend along at least a portion of the length 106. In some examples, the upper flap portion 146 may be higher than the bottom flap portion 148, or in some examples, the upper flap portion 146 may be the same height as the bottom flap portion 148. In addition, or instead, a series of one or more individual magnetic elements may be embedded in one or more of the upper flap portion 146 and the bottom flap portion 148, extending along at least one portion of the length L. In other embodiments, hook-and-loop fasteners or other types of fasteners may be used in combination with or instead of the magnetic fasteners to connect the upper flap portion 146 and the bottom flap portion 148 so that they can be detached from each other.

[0029] In the illustrated example, the flap portion 140 can be folded, in which case the upper flap portion 146 can be held in the folded state by a buckle and strap that spans the top of the container 100 between the back portion 160 and the front portion 130. The strap 164 and the fastener element or buckle 166A can be connected to the carry handle 136 of the front portion 130, and these can be used to hold the upper flap portion 146 in the folded state when detachably connected to the corresponding fastener element or buckle 166B connected to the carry handle 136 of the back portion 160 of the container 100.

[0030] Figures 8A and 8B show an exemplary curved member 230, and since this curved member may have the same shape and size as two other curved members, a curved member 240 can also be shown. Figure 8A shows a top view of the curved member 230, where the curved members 230 and 240 have curved portions that are separated from each other, and thus the curved members 230 and 240 may have outward-facing convex surfaces. Alternatively, or as needed, both curved members 230 and 240 may curve toward each other such that the curved members have outward-facing concave surfaces. Another option is that both curved members 230 and 240 may have curvatures that are oriented in the same direction (for example, the concave surfaces of both curved members 230 and 240 face the front of the container 100, or the concave surfaces of both curved members 230 and 240 face the back of the container 100). The curved member 230 may have a curvature defined by an inner radius R. The curvature may be described as a function of the length L of the opening 110, the strength of the magnets (i.e., the strength of the magnetic strips 300, 310), the horizontal distance between the ends 232, 234, and the desired stiffness of the curved members 230, 240. As shown in Figure 8A, portions of the curved members 230, 240 may have straight portions 233, 235. In some examples, the curvature of the curved members 230, 240 can be expressed as a percentage of the length L of the opening 110, given that the length L is measured when the opening 110 is closed. For example, the curvature of the curved member 230 may be about 30 percent of the length L of the opening 110, or about 38 percent of the length L, or within the range of 25 percent to 45 percent of the length L, or within the range of 15 percent to 60 percent of the length L.

[0031] As described above, the first curved member 230 may have a first end 232, a second end 234, and a curved member body 236 extending between the first end 232 and the second end 234. Similarly, the second curved member 240 may have a first end, a second end, and a curved member body extending between the first end and the second end. Each end 232, 234 of the curved members 230, 240 may have a curved profile as shown in Figure 8B. As shown in the figure, each end 232, 234 may have a lower section 231 with a larger radius than the upper section 233. In some examples, the radius of the lower section 231 may be up to three times larger than the radius of the upper section 233. Alternatively, each end 232, 234 may have a lower section with the same radius as the upper section. By having rounded profiles at each end 232, 234, the curved members 230, 240 can prevent any part of the container 100 (i.e., the outer shell 102, the inner liner 122, the insulation layer 124, or the receiving parts 250, 260) from being damaged when the ends 232, 234 move during the opening and closing process.

[0032] The curved members 230 and 240 can be formed from various materials and to various dimensions in order to produce the desired spring force for the closing mechanism 200. For example, in one example, the curved members 230 and 240 may include a core portion formed from alloy steel. In other examples, the curved members 230 and 240 may be formed from other metallic materials such as aluminum alloys, titanium alloys, or other metallic materials. The curved members 230 and 240 can be formed using an extrusion process and may have a substantially constant cross-sectional shape. The curved members 230 and 240 may have a substantially rectangular cross-sectional shape, but alternative cross-sectional shapes such as square, elliptical, circular, oblong, triangular, or other geometric shapes are possible. In some examples, the curved members 230 and 240 may have a concave or convex cross-sectional shape.

[0033] When a metal material is used for the core portion, the curved members 230, 240 may be provided with a non-metallic outer layer. The non-metallic outer layer may be an elastic or polymeric material, a polyethylene-based material, or a polyvinyl chloride-based material. This covering helps prevent corrosion of the core portion and helps protect the container components from any damage caused by the movement of the curved members 230, 240. The non-metallic outer layer may also help reduce friction of the curved members 230, 240 so that the ends 232, 234 can move freely. The non-metallic outer layer may have a constant or variable thickness. The covering may be applied as a heat-shrinkable tube on the metal core portion, or by injection molding, overmolding, dipping, or powder coating on the core portion, or by other means known to those skilled in the art.

[0034] In alternative examples, the curved members 230, 240 can be formed from non-metallic materials such as high-strength polymers like polycarbonate, fiber-filled glass materials (carbon or polymer, etc.), or composite materials. The non-metallic curved members may have end shapes similar to those described above and may or may not be encased in an elastic material. Alternatively, their thickness may be variable to adjust the stiffness and durability of the curved members.

[0035] Figures 9A-919 show illustrative magnetic strips 300, 310 of the closing mechanism 200. The closing mechanism 200 of the opening 110 can be formed using two magnetic strips 300 and 310. As previously stated, the opening 110 can be resealed using the closing mechanism 200. When the closing mechanism is in the closed state, the magnetic strips 300, 310 are in contact with each other. The magnetic strips 300, 310 may have sufficient magnetic strength to make a seal that is partially or completely waterproof and / or airtight. For example, such a magnetic strength may be about 4500 gauss, or in the range of 3500 to 5500 gauss, in which case the magnetic strength can be tested in the closed opening 110 using a magnetic tester placed directly between the two magnetic strips 300, 310. Alternatively, the magnetic strength may be tested using other means known to those skilled in the art.

[0036] The magnetic strips 300 and 310 shown in Figures 9A to 9B may have a structure similar to or identical to that described. While Figures 9A to 9B show the structure of magnetic strip 300, magnetic strip 310 may have a structure identical to or similar to that described with respect to magnetic strip 300. As shown in the example illustrated in Figure 9A, magnetic strip 300 may have tapered regions 317 at one or both ends. These tapered regions 317 can help ensure proper engagement and / or mounting of the magnetic strips 300 and 310, and can help ensure proper sealing of the closing mechanism 200. The tapered regions 317 may be formed on both magnetic strips 300 and 310, or on only one of the magnetic strips. As shown in Figure 9B, magnetic strip 310 may have a constant thickness and not have tapered regions at both ends. If necessary, both magnetic strips 300 and 310 may have a constant thickness and not have tapered regions. In addition, each magnetic strip 300, 310 may include a third or fourth polymer component.

[0037] Each magnetic strip 300, 310 may include a first member 320, a second member 360, and a plurality of magnetic elements 380. The first member 320 may include a plurality of receiving portions 350 on its front surface 322, and the plurality of receiving portions 350 may be arranged linearly as shown in Figure 19. If necessary, the receiving portions 350 may be arranged in an array having a plurality of matrices. The spacing between the receiving portions 350 may be minimal, or they may even be in contact with each other if the first receiving portions intersect with the second receiving portions. The first member 320 may also include a top surface 324, a bottom surface 326 opposite the top surface 324, a rear surface 328 opposite the front surface, and an upper shelf member 330 extending beyond the top surface 324. The upper shelf member 330 connects to the front surface 322 to form an upper shelf surface 332 that extends between the front surface 322 and the connecting surface 334 of the upper shelf member 330. The upper shelf member 330 may be used as a means for attaching or connecting the magnetic strip 300 to the container 100 using methods known in the art. The connecting surface 334 may be positioned at a predetermined distance from the front surface 322. The first member 320 may further include a lower shelf member 336. The lower shelf member 336 may include an engaging surface 338 positioned at a predetermined distance below the front surface 322. The engaging surface 338 may be positioned below the front surface 322 and at a distance below the connecting surface 334, as shown in Figure 12. A lower shelf surface 340 may be formed between the front surface 322 and the engaging surface 338. The lower shelf surface 340 may include a plurality of recesses 342 extending toward the upper shelf surface 332 (i.e., toward the top surface 324), the apex of each recess 342 may be located between two receiving portions 350.

[0038] Each receiving portion 350 may include a side wall surface 352 and a bottom surface 354. In some examples, each receiving portion 350 may include a slot 356 along the side wall surface 352, the slot 356 extending from the bottom surface 354 to the front surface 322. Multiple magnetic elements 380 are received within multiple receiving portions 350. For example, each magnetic element 380 can be received individually within a corresponding receiving portion 350. In some examples, the top surface 382 of each magnetic element can be positioned below the front surface 322 of the first member 320 at a predetermined distance, such as between 0.05 mm and 0.40 mm, or between 0.025 mm and 0.060 mm. Although the magnetic elements 380 are shown as circular magnetic elements, the magnetic elements may be of any shape, such as rectangular, square, triangular, elliptical, or other geometric shapes known to those skilled in the art. The magnetic elements 380 can be arranged such that adjacent magnetic elements 380 have opposite polarity. For example, as shown in Figure 17, the magnetic elements 380 in the receiving section 350A may be positioned with their north poles facing the front surface 322, the magnetic elements 380 in the receiving section 350B may be positioned with their south poles facing the front surface 322, and the magnetic elements 380 in the receiving section 350C may be positioned with their north poles facing the front surface 322. Alternatively, the magnetic elements 380 may have alternating or repeating polarities. For example, two or more magnetic elements 380 with the same polarity may be followed by two or more magnetic elements 380 with opposite polarities. The magnetic elements 380 can be magnetized before or after being installed in their respective receiving sections 350.

[0039] The second member 360 can be connected to or coupled to the first member 320 to cover the multiple magnetic elements 380 located within the multiple receiving portions 350 of the first member 320. The second member 360 can help secure the magnetic elements 380 to the magnetic strip 300. The slot 356 can cover the magnetic elements 380 and prevent the formation of air bubbles when the second member 360 is connected to the first member 320 using a molding process (e.g., a second shot injection molding process). The slot 356 is provided in a small volume to prevent it from being filled with molten polymer material during the molding process, while providing a small volume from which air can be pushed out. The second member 360 may include a top surface 362 that contacts the upper shelf surface 332 of the first member 320, a front surface 364 that contacts the front surface 322 of the first member 320, and a plurality of projections 366 extending from the front surface 364 of the second member 360. Each projection 366 may extend into a corresponding receiving portion 350 of the first member 320. The projections 366 may help to secure the magnetic element 380 within the receiving portion 350. In some examples, a portion of each projection (or at least one projection) 366 may contact the top surface 382 of the corresponding magnetic element 380 positioned within the corresponding receiving portion 350. The second member 360 may further include an engagement surface 368 that contacts the lower shelf surface 340 of the first member 320. The engagement surface 368 may include a plurality of projections 370 extending into a plurality of recesses 342. Each projection 370 is received into and in contact with the corresponding recess 342 of the first member 320. In addition, each projection 370 can be fitted into each corresponding recess 342 of the lower shelf surface 340 such that the engaging surface 368 of each projection 370 has the same shape as the corresponding recess 342 of the lower shelf surface 340 so that the corresponding surfaces fit together without gap or with minimal gap between them. In addition, the second member 360 may have a rear surface 372 opposite to the front surface 364, where the rear surface 372 may be substantially coplanar with the connecting surface 334 of the upper shelf member 330.

[0040] In some examples, the magnetic strips 300 and 310 can be formed using an injection molding process after the first member 320 has been molded and before the second member 360 has been molded, with the magnetic elements 380 already installed. For example, the first member 320 can be molded, and then each of the magnetic elements 380 can be installed in each corresponding receiving portion 350. The magnetic elements 380 are installed in the receiving portions 350, leaving a small gap between the top surface 382 and the front surface 322 of each magnetic element. Once the magnetic elements 380 are positioned in their corresponding receiving portions 350, the second member 360 can be molded on the first member 320 to cover the magnetic elements 380 and fix it to the magnetic strip 300. As an example, the magnetic strips 300 and 310 can be made of thermoplastic polyurethane (TPU). Each member 320 and 360 can have a thickness sufficient to fix the magnetic elements 380 without significantly reducing the strength of the magnetic elements 380. However, to construct the magnetic strips 300 and 310, it is conceivable to use a combination of polymers, metals or alloys, textiles, or carrier scrims. The first member 320 and the second member 360 may be made from the same material or from different materials. These materials may be hydrophobic and easy to clean. However, to construct the magnetic strips 300 and 310, it is conceivable to use a combination of polymers, metals, or alloys.

[0041] The magnetic strips 300 and 310 may be connected to the front portion 130 and the rear portion 160 using any fixing method, technique, and / or technology. The connecting surface 334 and the rear surface 372 can be coupled or connected to the front portion 130 of the outer shell 102. In some examples, the ends of each magnetic strip 300, 310 can be welded to the container 100. To prevent distortion of the magnetic strips 300, 310 during the connection process, one or more relief holes or openings 319 may be provided near the ends of each magnetic strip 300, 310, as shown in Figures 9A-9B. The relief holes 319 are outside the receiving portion 350 and can help prevent distortion of the magnetic strips 300, 310 during the connection process by providing a position for receiving the fluid material generated by the connection process. The relief holes 319 may be blind holes having a predetermined depth or they may penetrate the magnetic strips 300, 310. The relief holes 319 are located in one tapered region 317 of the magnetic strips 300, 310 and may have a diameter smaller than the diameter of the receiving portion 350. In the illustrated example, two relief holes 319 are shown near each end of the magnetic strips 300, 310, but the number of relief holes 319 may be one, three, or more than three holes near each end. In addition, the relief holes 319 may have any geometric shape, and furthermore, the magnetic element 380 fixed within the receiving portion 350 may be made of any material without departing from the scope of this disclosure.

[0042] The main seal of the insulated container 100 is created by the closing mechanism 200 of the opening 110. Specifically, when the closing mechanism 200 is closed, the rear surface 328 of the first member 320 of the magnetic strip 300 can come into contact with the rear surface 328 of the first member 320 of the magnetic strip 310, thereby creating a seal by the magnetic force of the magnetic strips 300 and 310. Alternatively, a seal can be created by bringing the rear surface 372 of the second member 360 of the magnetic strip 300 into contact with the rear surface 372 of the second member 360 of the magnetic strip 310, thereby creating a seal by the magnetic force of the magnetic strips 300 and 310. In addition, an auxiliary seal can be created by folding the flap portion 140. Together, the main seal and the auxiliary seal can make the insulated container 100 substantially waterproof and / or airtight. In certain specific examples, the insulated container 100 may be configured to hold water (e.g., melted ice) without water leaking from the storage compartment 120 to the external environment through the opening 110, or with minimal water leakage. In certain specific examples, the insulated container 100 may be configured to be placed with its side (e.g., front portion 130 or rear portion 160) facing down, and / or upside down (with the opening 110 facing downward), and the container 100 may be configured to prevent or substantially reduce the seepage of water held in the storage compartment 120 when it is held in one of these positions for an extended period. In a specific example, the insulated container 100 can be configured such that, when the insulated container 100 is held upside down with its opening 110 tilted at 90 degrees (i.e., upside down), 60 degrees, 45 degrees, 30 degrees, or 0 degrees (i.e., the container is held with its front portion 130 or back portion 160 facing downwards) for at least 1 minute, 2 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, 45 minutes, or 1 hour, less than 5%, less than 2%, less than 1%, less than 0.5%, less than 0.1%, less than 0.01% of the water (or water and ice combination) held in the storage compartment 120 leaks through the opening 110.

[0043] Figures 20-22 show alternative magnetic strips 400 configured to replace magnetic strips 300 and / or 310 of a closing mechanism 200 for an exemplary container 100. The magnetic strip 400 may be formed from a first member 420 and a second member 460, along with a plurality of magnetic elements 480. As shown in Figure 20, the magnetic strip 400 may have tapered regions 417 at one or both ends. These tapered regions 417 can help ensure proper engagement and / or mounting of the magnetic strip 400 and thus ensure proper sealing of the closing mechanism 200. The tapered regions 417 may be formed on both sides of the magnetic strip 400 or on only one side of the magnetic strip. In some examples, the magnetic strip 400 may not include the tapered regions 417.

[0044] The first member 420 may comprise a plurality of receiving portions 450, each having a plurality of retaining members 433 that partially cover each magnetic element 480. The first member 420 may include a front surface 422, a top surface 424, a bottom surface 426 opposite the top surface 424, a rear surface 428 opposite the front surface 422, and an upper shelf member 430 extending beyond the top surface 424. The upper shelf member 430 connects to the front surface 422 to form an upper shelf surface 432 that extends between the front surface 422 and the connecting surface 434 of the upper shelf member 430. The plurality of receiving portions 450 and their corresponding magnetic elements 480 may be arranged linearly. If necessary, the receiving portions 450 and magnetic elements 480 may be arranged in a matrix. The connecting surface 434 may be positioned at a predetermined distance from the front surface 422.

[0045] The first member 420 may further include a recessed passage 423 within the front surface 422. In some examples, the passage 423 may include an opening or a number of openings 425. These openings 425 may be blind holes or through holes. As described below, these passages 423 and openings 425 can help to secure the second member 460 to the first member 420.

[0046] Each receiving section 450 may comprise a side wall surface 452, a bottom surface 454, and a plurality of retaining members 433. The retaining members 433 of each receiving section 450 can contact the upper surface of each corresponding magnetic element 480 to secure the magnetic element 480 to the first member 420. Each retaining member 433 may extend outward from the front surface 422 and then extend inward toward the center of each receiving section 450. Each retaining member 433 may partially span the upper surface of each magnetic element, as shown in Figure 21. The retaining members 433 may be substantially triangular or of other geometric shapes. In the example shown in Figure 21, each receiving section 450 may comprise five retaining members 433 arranged as a series of retaining members, each positioned at regular intervals along the outer circumference of the side wall surface 452. However, the number of retaining members may be more or less than five.

[0047] Each magnetic element 480 can be individually housed within its corresponding receiving portion 450. The properties of the magnetic elements 480 in terms of shape and size may be the same as those of the magnetic elements 380 described above. In addition, the polarity of the multiple magnetic elements 480 may be similar to that of the multiple magnetic elements 380 described above.

[0048] The second member 460 may be connected to or coupled to the first member 420 to cover a plurality of magnetic elements 480 located within a plurality of receiving portions 450 of the first member 420. The second member 460 can help secure the magnetic elements 480 to the magnetic strip 400. The second member 460 may have a top surface 462 that contacts the upper shelf surface 432 of the first member 420 and a front surface that contacts the front surface 422. In addition, the second member 460 may include a plurality of projections 466, each projection 466 arranged to contact the magnetic elements 480, and each projection 466 has a shape complementary to each set of retaining members 433 of each receiving portion 450.

In addition, the second member 460 may include one or more projections (not shown) extending into the passage 423 of the first member 420. Each projection may include an extension that further extends into the opening 425. The projections and protrusions 466 help to form an interlocking shape to further secure the second member 460 to the first member 420.

[0049] In some examples, the magnetic strip 400 can be formed using an injection molding process with the magnetic elements 480 mounted on a machine tool, and the first member 420 is molded around a plurality of magnetic elements 480 such that the magnetic elements 480 are fixed to the first member 420 when the first member 420 is formed. The magnetic elements 480 can be fixed in the machine tool using claws or tabs connected to the outer circumference of the magnetic elements 480 so that the first member 420 and the corresponding retaining members 433 are formed integrally. The claws or tabs are then removed, thereby leaving the magnetic elements 480 fixed within the receiving portion 450 of the first member 420. If claws or tabs are not positioned around the magnetic elements 480, the retaining members 433 are formed. Each retaining member 433 can be formed as part of the first member 420 so that the retaining member 433 and the first member 420 are formed as a single unit. Next, the second member 460 can be molded onto the first member 420 to cover the magnetic element 480 and fix it to the magnetic strip 400. The first and second members 420 and 460 may be constructed using any of the materials previously described with respect to the magnetic strips 300 and 310.

[0050] Figures 23–26 show alternative magnetic strips 500 that may be configured to replace magnetic strips 300 and / or 310 of the closing mechanism 200 for the exemplary container 100. The magnetic strip 500 may be formed from a first member 520, a second member 560, and a magnetic element assembly 581 that forms a sleeve molded to cover a plurality of magnetic elements, as shown in Figure 26.

The first member 520 may include a receiving portion having the corresponding shape of the magnetic element assembly 581. For example, the receiving portion may constitute a cistern having a large-diameter region that receives the corresponding large-diameter region 583 of the magnetic element assembly 581 and a small-diameter region that receives the corresponding small-diameter region 585 of the magnetic element assembly 581. The first member 520 may include a front surface containing a receiving portion, a rear surface 528 opposite the front surface, an upper surface 524, a bottom surface 526 opposite the upper surface 524, and an upper shelf member 530 extending beyond the upper surface 524.

[0051] The first member 520 may further include a recessed passage 523 on its front surface. In some examples, the passage 523 may include an opening or a number of openings 525. These openings 525 may be through holes. As described below, these passages 523 and openings 525 can help secure the second member 560 to the first member 520. These passages 523 and openings 525 may be similar to the passages 423 and openings 425 described with respect to the magnetic strip 400.

[0052] The properties of the magnetic elements fixed within the magnetic element assembly 581 in terms of shape and size may be the same as those of the magnetic elements 380 described above.

In addition, the second member 560 may include one or more projections (not shown) that extend into the passage 523 of the first member 520. Each projection may include an extension 565 that extends to the opening 525 and to the rear surface 528 of the first member 520. Each extension 565 may have a cylindrical shape with multiple diameters. For example, the second end of each extension 565 may have a larger diameter at the end closer to the rear surface 528 than at the first end opposite the second end. The upper surface of the second end may be coplanar with the rear surface 528 of the first member 520. Such a larger end at the second end helps to form an interlocking shape for further securing the second member 560 to the first member 520.

[0054] In some examples, the magnetic element assembly 581 can be formed by covering a linear arrangement of magnetic elements with a sleeve. The magnetic element assembly 581 can be attached to a workpiece, where a first member 520 is formed around at least a portion of the magnetic element assembly 581 using an injection molding process. A second member 560 can then be formed on the first member 520 to further cover the magnetic element assembly 581 and secure it to the magnetic strip 500. Each projection and extension 565 can be formed together with the second member 560 as a single unit. In one example, the magnetic element assembly 581 can be held in place within the workpiece using an opening 563 formed within the second member 560. The first and second members 520, 560 may be constructed using any of the materials previously described with respect to the magnetic strips 300, 310.

[0055] Figures 27–30 show alternative magnetic strips 600 that may be configured to replace magnetic strips 300 and / or 310 of a closing mechanism 200 for an exemplary container 100.

[0056] The first member 620 may have a plurality of receiving sections 650 for receiving magnetic elements 680. Each receiving section 650 may have a central peg 651 extending from the bottom surface 654 of each receiving section 650, and a side wall surface 652. Each central peg 651 may be formed as part of the first member 620 such that the central peg 651 and the first member 620 are formed as a single unit. The first member 620 may include a front surface 622, a top surface, a bottom surface 626 opposite the top surface, a rear surface opposite the front surface 622, and an upper shelf member 630 extending beyond the top surface. The upper shelf member 630 connects to the front surface 622 to form an upper shelf surface 632 that extends between the front surface 622 and the connecting surface 634 of the upper shelf member 630. The plurality of receiving sections 650 and their corresponding magnetic elements 680 may be arranged linearly. If necessary, the receiving portion 650 and the magnetic element 680 may be arranged in an array having multiple matrices. The connecting surface 634 may be positioned at a first predetermined distance from the front surface 622.

[0057] The first member 620 may further include a recessed passage 623 within the front surface 622. In some examples, the passage 623 may include an opening or a number of openings 625. These openings 625 may be blind holes or through holes. As described below, these passages 623 and openings 625 can help to secure the second member 660 to the first member 620.

[0058] Each magnetic element 680 can be individually received within a corresponding receiving portion 650. Furthermore, each magnetic element 680 may have a central opening 681 for receiving a central peg 651 located within each receiving portion 650. The central opening 681 of the magnetic element 680 may be similar in size and shape to the cross-sectional profile of the central peg 651. Each central peg 651 may include an undercut 653. The properties of the magnetic element 680 in terms of shape and size may be the same as those of the magnetic element 380 described earlier. In addition, the polarity of the multiple magnetic elements 680 may be similar to that of the multiple magnetic elements 380 described earlier.

[0059] The second member 660 may be connected to or coupled to the first member 620 to cover a plurality of magnetic elements 680 located within a plurality of receiving portions 650 of the first member 620.

The second member 660 may have a top surface that contacts the upper shelf surface 632 of the first member 620 and a front surface that contacts the front surface 622. In addition, the second member 660 may include a plurality of projections 666, each projection 666 arranged to contact the magnetic elements 680, and each projection 666 has a shape complementary to each receiving portion 650 and also includes a pocket to receive the upper end of each central peg 651. Each projection 666 may extend into the corresponding receiving portion 650 as previously described with respect to projection 366. In addition, the second member 660 may include one or more projections (not shown) extending into the passage 623 of the first member 620. Each projection may include an extension that further extends into the opening 625. The projections and protrusions 666 help to form an interlocking shape to further secure the second member 660 to the first member 620.

[0060] In some examples, the magnetic strip 600 can be formed using an injection molding process after the first member 620 has been formed and before the second member 660 has been formed, with the magnetic elements 680 already installed. For example, the first member 620 can be formed, and then the corresponding central pegs 651 can be received into the central openings 681 of each magnetic element 680, thereby installing each magnetic element 680 into its corresponding receiving portion 650. Once the magnetic elements 680 are positioned in their corresponding receiving portions 650, the second member 660 can be formed on the first member 620 to cover the magnetic elements 680 and secure it to the magnetic strip 600. The first and second members 620, 660 may be constructed using any of the materials previously described with respect to the magnetic strips 300, 310.

[0061] Figures 31-32 show alternative magnetic strips 700 that may be configured to replace magnetic strips 300 and / or 310 of a closing mechanism 200 for an exemplary container 100.

Each magnetic element 780 is individually received within a corresponding magnetic cover 790 and can be fixed to the magnetic cover 790 by adhesive, friction fitting, bonding, welding, thermocompression, or other means known to those skilled in the art. The magnetic covers 790 can then be attached to the first member 720 by adhesive, high-frequency welding, or other methods known to those skilled in the art. In some examples, the plurality of magnetic covers 790 may be formed as a single unit having individual pockets for receiving each magnetic element 780. Once the magnetic cover 790 equipped with the magnetic elements 780 is fixed to the first member 720, the second member 760 can be connected or coupled to the first member 720 to cover the magnetic cover 790 and completely fix each magnetic element 780 within each magnetic cover 790. The second member 760 may have a plurality of receiving portions 750 on its front surface 762 to receive each magnetic cover 790.

[0062] In some examples, each magnetic cover 790 may have a slot 719 or more slots 719 passing through the rear surface 792 of the magnetic cover 790. In addition, each magnetic cover 790 may have a stepped front surface such that the front surface has multiple steps 793.
