[0038] Referring now to FIGS. 1-17, there is shown a system of nesting magnetic tableware 10. The system of nesting magnetic tableware 10 is embodied in FIGS. 1-4 by a tableware set including two pieces of nesting dishware, B.sub.1 and P, and two utensils, F and K. In this embodiment, one piece of dishware is a shallow bowl By and the other piece of dishware is a plate P, while one utensil is a fork F and the other is a knife K. However, it is to be understood that the number of utensils and pieces of dishware depicted in the drawings is limited for purposes of clarity, and that in other embodiments, the number of utensils and pieces of dishware can be greater or fewer than shown in the drawings. It is also to be understood that the type of each utensil or piece of dishware can be different than what is shown in the drawings.

[0039] For example, in FIGS. 5-17 the system of nesting magnetic tableware 10 is alternatively embodied by a tableware set including two pieces of dishware in the form of two identical nesting bowls B.sub.2, B.sub.2. The pieces of dishware B.sub.2, B.sub.2 in the tableware set depicted in FIGS. 5-17 are identical in all respects to the pieces of dishware B.sub.1, P in the tableware set depicted in FIGS. 1-4 except that bowls B.sub.2 are deeper than either of bowl B.sub.1 or plate P. It is to be understood that additional bowls B.sub.1, B.sub.2, plates P, and utensils such as fork F and knife K, or even differently shaped dishware and utensils (e.g., a spoon), can optionally be combined to form a tableware set customized to a given user's needs. Dishware B.sub.1, B.sub.2, P and utensils F, K suitable for use in system for nesting magnetic tableware 10 of the present invention can be formed from any desired polymeric or metallic material or combination of materials, including but not limited to polypropylene, carbon fiber, stainless steel, and aluminum.

[0040] Each piece of dishware in a system of nesting magnetic tableware 10 of the present invention, including but not limited to B.sub.1, B.sub.2, P, is configured to nest at least partially within another piece of dishware when stacked, as best shown in FIGS. 3 and 6. Each piece of dishware in a system of nesting magnetic tableware 10 includes a well 12, a rim 14, and one or more alignment magnets 15 affixed to the rim 14. In the illustrated embodiments, each piece of dishware includes a pair of alignment magnets 15 affixed to the rim 14. The well 12 defines a space in which a volume of liquid can be contained without spilling when the piece of dishware is in an upright position on a level surface. The well 12 has a depth and a width. Bowl By has a well 12 with a depth greater than that of plate P, while bowls B.sub.2 have a well 12 with a depth greater than that of either of bowl B.sub.1 or plate P. The rim 14 of each piece of dishware is generally planar and extends horizontally outward the from the well 12. The pieces of dishware forming a tableware set can have any general shape (i.e., footprint), including but not limited to circular, square, and rectangular. In embodiments where the dishware has a generally circular shape, such as the bowls B.sub.1, B.sub.2, and plate P depicted in the drawings appended hereto, the rim 14 extends radially outward the from the well 12. In some embodiment, all pieces of dishware in the tableware set have rims 14 of similar inner and outer diameters, but the pieces themselves can vary in depth from the rim 14 (i.e., well depth) to form a plate P or different types and sizes of bowls B.sub.1, B.sub.2.

[0041] Referring again to FIGS. 1-17, the rim of each piece of dishware B.sub.1, B.sub.2, P includes a substantially planar upper surface 16 and an opposing substantially planar lower surface 18. Each rim 14 defines a pair of outwardly (i.e., horizontally) protruding tabs 20 at opposing lateral sides of the well 12. As such, each tab 20 of a pair is part of the rim 14 of a given piece of dishware B.sub.1, B.sub.2, P. The pair of tabs 20 serve as handles by which a user can easily carry a given piece of dishware B.sub.1, B.sub.2, P and avoid potential burns caused by hot food in the well 12. However, in other embodiments, the tabs 20 can be omitted and the rims 14 can have a uniform width around the perimeter of the well 12. In some embodiments, each rim 14 has a uniform width at least as wide as the diameter of the alignment magnets 15 affixed thereto.

[0042] Each pair of alignment magnets 15 is affixed to the tabs 20 above the upper surface 18 of the rim 14 of each piece of dishware B.sub.1, B.sub.2, P. Each alignment magnet 15 is spaced around the rim 14 from each other alignment magnet 15. As such, each pair of alignment magnets 15 is affixed to the rim 14 of each piece of dishware B.sub.1, B.sub.2, P at opposing lateral sides of the well 12. A pair of recesses 22 is defined in the lower surfaces 18 of the tabs 20 of each rim 14. Each recess 22 is vertically aligned with each respective alignment magnet 15 on the upper surface 18 of the rim 14 of the same piece of dishware. As such, each recess 22 in a given piece dishware rim 14 corresponds to each alignment magnet 15. In other embodiments, the pair of alignment magnets 15 can be affixed to the rim 14 (e.g., at a tab 20) below the lower surface 18, and the pair of corresponding recesses 22 can be formed in the upper surface 16 of the rim 14. As such, the alignment magnets 15 can be affixed to the rim 14 either above the upper surface 16 or below the lower surface 18, and the corresponding recesses 22 can be formed in the surface of the rim 14 opposing the surface of the rim 14 to which the magnets 15 are affixed.

[0043] Each recess 22 of each piece of dishware B.sub.1, B.sub.2, P is sized and shaped to at least partially receive an alignment magnet 15 of another piece of dishware B.sub.1, B.sub.2, P. Thus, the alignment magnets 15 of a first piece of dishware will fit into the corresponding recesses 22 of a second piece of dishware and engage the alignment magnets 15 of the second piece (see e.g., FIGS. 2-3 and 5-6). Likewise, each alignment magnet 15 of each piece of dishware is sized and shaped to be received in a recess 22 of another piece of dishware B.sub.1, B.sub.2, P or utensil F, K. In this way, the alignment magnets 15 of each piece of dishware are configured to engage the recesses 22 of an adjacent piece of dishware when multiple pieces of dishware are nested in a stack and the alignment magnets 15 of each respective adjacent piece of dishware are placed in proximity to one another, as best shown in FIGS. 2, 4-5, and 13. The alignment magnets 15 of each piece of dishware pull the magnets 15 of one piece into engagement with the recesses 22 of another piece when multiple pieces of dishware are nested and their tabs 20 are placed in proximity to one another. This maintains each piece of nested dishware in a neat and orderly stack. The use of pairs of protruding alignment magnets 15 and corresponding recesses 22 on each piece of dishware B.sub.1, B.sub.2, P provides two points of mating contact between adjacent pieces of dishware in a nested stack. This prevents individual pieces of dishware from spinning or rotating while nested in a stack.

[0044] Each piece of dishware is also configured to mount one or more utensils such as a fork F, a knife K, or a spoon (not shown) on the rim 14 thereof. Each utensil includes a substantially planar handle 26 having an upper surface 16 and a lower surface 18. A magnet 15 is affixed to the handle above the upper surface 16. A recess 22 is formed in the lower surface of the handle 26. The magnet 15 of a piece of dishware can engage the recess 22 of the utensil F, K when the magnet 15 of the utensil F, K is placed in placed in proximity to the tab 20 of the piece of dishware B.sub.1, B.sub.2, P. In this way, the utensils F, K are configured to attach to the alignment magnets 15 about the rims 14 of pieces of dishware B.sub.1, B.sub.2, P to secure handle of a knife K, fork F, or spoon (not shown) to the piece of dishware so that wind or waves will not dislodge the utensils from the rim 14 of the piece of dishware. This also advantageously prevents utensils from being accidentally dropped on the ground and frees a user's hands from needing to separately carry or hold utensils when not in use.

[0045] Each alignment magnet 15 can be affixed to the respective tab 22 of each piece of dishware B.sub.1, B.sub.2, P by a magnet housing 24. Each magnet housing 24 can be made from any suitably durable polymeric material, such as polypropylene or acetyl. Each magnet housing 24 contains one alignment magnet 15. Each magnet housing 24 extends through a hole 21 in the tab 20 of each dishware rim 14 such that the magnet housing 24 extends above the upper surface 16 and below the lower surface 18 of the rim 14. Each magnet housing 24 also defines each recess 22 in the lower surface 18 of each rim 14. As best shown in FIG. 13, the magnet housings 24 affix the alignment magnets 15 to the rim 14 above the upper surface 16 of the tabs 20. Each magnet housing 24 and the magnet 15 contained therein forms a protrusion 25 that extends above the upper surface 16 of the tab 20. The protrusion 25 is receivable in the recess 22 of an overlying nested (i.e., adjacent) piece of dishware B.sub.1, B.sub.2, P or utensil F, K. When the protrusion 25 of a first piece of dishware is received in the recess of a recess 22 of an overlying nested piece of dishware, the alignment magnet 15 contained in the magnet housing 24 of the first piece of dishware engages the alignment magnet 15 contained in the magnet housing 24 of the second piece of dishware to secure the two pieces of dishware together. In other embodiments, each magnet housing 24 can affix an alignment magnet 15 below the lower surface 18 of the rim 14 and define a recess 22 in the upper surface 16 of the rim 14.

[0046] Referring now to FIGS. 7-9 and 13, each magnet housing 24 is formed a female portion 26 and a male portion 28. The female portion 26 defines the recess 22 of each piece of dishware B.sub.1, B.sub.2, P. The male portion 28 defines the protrusion 25 of each piece of dishware B.sub.1, B.sub.2, P. The protrusion 25 is receivable in a recess 22 of another piece of dishware B.sub.1, B.sub.2, P or utensil F, K. The male portion 28 also defines an internal cavity 29 in which an alignment magnet 15 is received. The female portion 26 is secured to the male portion 28 to seal the magnet 15 inside the magnet housing 24. The female portion 26 can be secured to the male portion 28 using methods known in the art, including but not limited to sonic welding, adhesive, friction fits, and the like. The female portion 26 defines a protruding stop 27. The stop 27 is engaged with a notch 31 formed in one side of the hole 21 in each rim 14. Engagement of the stop 27 with the notch 31 prevents the magnet housing 24 from rotating or spinning with the hole 21, and thereby reduces rattling when pieces of dishware B.sub.1, B.sub.2, P are nested in a stack for storage or transport.

[0047] Turning now to FIGS. 10-17, each piece of dishware B.sub.1, B.sub.2, P in a system of nesting magnetic tableware 10 of the present invention can further include one or more bumpers 30. The bumpers 30 are configured to absorb shock, reduce rocking, rattling, and vibration, and dampen sound produced when multiple pieces of nested magnetic dishware B.sub.1, B.sub.2, P are transported or otherwise moved. Each piece of dishware B.sub.1, B.sub.2, P includes a pair of bumpers 30. A pair of bumpers 30, combined with a pair of alignment magnets 15 and corresponding recesses 22 as noted above, can provide four points of contact between the rims 14 of adjacent pieces of nested dishware B.sub.1, B.sub.2, P in a stack, thereby maximizing stability of the stack and minimizing sound produced by each piece of dishware B.sub.1, B.sub.2, P therein during transport.

[0048] Each bumper 30 of each pair is affixed to the rim 14 at opposing lateral sides of the well 12 and is spaced around the rim 14 substantially equidistantly between the pairs of tabs 20 and alignment magnets 15. Each bumper 30 extends through the rim 14 both above the upper surface 16 and below the lower surface 18. Each pair of bumpers 30 on each piece of dishware B.sub.1, B.sub.2, P is configured to engage the pair of bumpers 30 on an adjacent piece of dishware B.sub.1, B.sub.2, P when the pair of magnets 15 of one of the pieces of dishware B.sub.1, B.sub.2, P is engaged with the pair of recesses 22 in the other piece of dishware B.sub.1, B.sub.2, P. Put differently, four pairs of bumpers 30 on two vertically adjacent (i.e., nested) pieces of dishware B.sub.1, B.sub.2, engage each other to stabilize and dampen vibration of the pieces of dishware B.sub.1, B.sub.2, when the magnets 15 of one piece are engaged with the recesses 22 of another piece, as best shown in FIGS. 11-17. In this way, each pair of bumpers 30 on each piece of dishware B.sub.1, B.sub.2, P engages the pair of bumpers 30 of each respective overlying and underlying piece of dishware when multiple pieces of dishware B.sub.1, B.sub.2, P are nested in a stack.

[0049] To ensure that the bumpers 30 do not become dislodged from the rims 14 of the dishware, the rim 14 of each piece of dishware can include two pairs of secondary apertures 31 defined therethrough at opposing lateral sides of the well 12. A portion of each bumper 30 can extend through each secondary aperture 31. In some embodiments, each bumper 30 can include two spaced support posts 32 and two opposing (i.e., upper and lower) extension portions 34. The support posts 32 extend through each pair of secondary apertures 31. The upper and lower extension portions 34 connect the support posts 32 above the upper surface 16 and below the lower surface 18 of the rim 14. Formation of the bumpers 30 around (i.e., through, over, and under) a portion of each rim 14 prevents the bumpers 30 from becoming inadvertently dislodged from the rim 14. Each bumper 30 can be secured to the rim 14 and the secondary aperture 31 by overmolding. Each bumper 30 can be formed from any durable elastic material, including thermoplastic polyurethane, rubber, and the like.
