Abstract

A set of nestable and stackable cookware, for example, a set of pots and pans, is maintained in a stable configuration by stops attached to the outer walls of the cookware. Each stacked and nested item of cookware is supported on the rim of the lower item by two stops attached to its outer wall, on opposite sides of the item. Each stop is shaped and configured to contact the rim of the lower item in the stack at a finite number of points. The points of contact lie in the same plane, which uprightly supports the stacked cookware item on the lower cookware item, without the walls or the base of the stacked cookware item touching the lower item.

Description

STACKABLE AND NESTABLE COOKWARE HAVING A STABLE CONFIGURATION

FIELD AND BACKGROUND OF THE INVENTION

The subject technology relates to household or commercial cookware items, for example, pots and pans, which are structured and configured to stack and nest together. It is desirable for a stack of cookware items to be stacked and nested in a stable configuration, so that the stacked and nested items have little or no tendency to rock or shift within the stack when the stack is moved by a user, or when items are added to the stack. Cookware items may include attached handles extending from the items, which may impede the ability of these items to stack and nest in a stable configuration. A simple, rugged and low-cost design is also desirable for cookware items.

SUMMARY OF THE INVENTION

According to an aspect of the subject technology, a set of cookware, for example a set of pots and pans, consists of individual cookware items sized in a series of increasing diameters, or having tapering walls, so they can nest together. At least some of the cookware items are provided with one or more stops attached to the outside of the items, to support the nested items by contacting the lip or rim of the lower items into which they are nested.

Preferably, without limitation, a stop for a stacked cookware item according to the subject technology consists of a horizontal bar attached to the outer surface of the cookware item. A cookware item may have one, two, or more stops attached to its outer surface. To improve the stability of the stacked configuration, according to an aspect of the subject technology, the stop or stops of an item contact the rim or lip of the next lower item in the stack at exactly

2019201905 23 Mar 2020 three or exactly four contact points. Preferably, the three or four contact points are co-planar, i.e. are lying in the same plane, so that the upper cookware item is supported in a stable configuration on the lower cookware item, with little or no tendency to rock. The number of contact points is determined by the configuration of the lower edges of the stops. A stop having a non-linear lower edge may provide for exactly one or exactly two contact points, as described herein. Thus, a cookware item having two stops may have exactly three or exactly four contact points with the rim or lip of next lower item (i.e. the item into which it is nested).

[0004] Accordingly in a first aspect the present invention provides a cookware set of stackable and nestable cookware items comprising:

a first cookware item comprising a first base, a first wall rising from the first base and integral with the first base, a first rim at the top of the first wall and integral with the first wall, a first stop connected to an exterior of the first wall between the first base and the first rim and extending outwardly from the first wall, and a second stop connected to an exterior of the first wall between the first base and the first rim and extending outwardly from the first wall;

a second cookware item comprising a second base, a second wall rising from the second base and integral with the second base, a second rim at the top of the second wall and integral with the second wall;

the first cookware item stacked on and nested within the second cookware item, provided that the first base and first wall are not contacting the second base or second wall;

2019201905 23 Mar 2020 the first stop directly contacting the second rim at exactly two contact points, and the second stop directly contacting the second rim at exactly two contact points, so that the first cookware item is supported directly on the second rim at the contact points in a stacked and nested position in the second cookware item; and wherein the first stop has a lower edge having a non-linear profile which defines the exactly two contact points and the second stop has a lower edge having a non-linear profile which defines the exactly two contact points; and wherein the first stop has a left end and a right end spaced apart from the left end, the exactly two contact points of the first stop disposed and spaced apart on the left end and the right end; and wherein the second stop has a left end and a right end spaced apart from the left end, the exactly two contact points of the second stop disposed and spaced apart on the left end and the right end.

[0046]	According to a non-limiting aspect of the subject technology, the Figures show views of cookware items and of nested stacks of three cookware items. Each

2019201905 19 Mar 2019 cookware item has a base, and a wall rising from the base and integral with the base, which terminates at an integral lip or rim at the top of the item. The items are sized and shaped to stack in a nesting configuration as shown, for example, in Figures 1-8. Each item has an internal diameter, and to enable nesting, the internal diameter of each item is at least slightly smaller than the item beneath it in the stack. Alternatively, to enable nesting, the walls of the items taper outward from the base toward the lip or rim. It will be understood that a stack of nested cookware items according to the subject technology could have as few as two items and more than three items.

[0047] As shown in the non-limiting embodiments of Figures 1-8, according to the subject technology, a nested stack 10 of three cookware items, specifically a top item 11, middle item 12, and bottom item 13 is maintained in a stable configuration by stops 14 attached to the outer surface of top item 11 and stops 15 attached to middle item 12. Stops 14 attached to top item 11 contact the rim 16 of middle item 12. Stops 15 attached to middle item 12 contact the rim 17 of bottom item 13. In this embodiment, items 11, 12 have two attached stops 14, 15, disposed on opposite sides of each item as shown. Preferably, these stop-to-rim contacts are the only points of contact between the nested items 11, 12, 13, i.e., the walls and/or bases of the items are not in contact.

[0048] The stops 14, 15 are attached to the exterior of the walls of the items 11, 12, 13, by welding for example, or are attached by fasteners 18 (only one pair of fasteners is numbered) such as rivets, bolts or screws through small holes formed in the walls for that purpose. Preferably the stops are curved to conform to the

2019201905 19 Mar 2019 curvature, if any, of the walls to which they are attached. Preferably, for attachment to a cookware item with tapering or sloping outer walls, the surface of the stop facing the wall (i.e. the inner surface) is likewise tapered or sloped to conform to the wall. The opposite (i.e. outer) surface of the stop may be tapered, sloped, or square, with respect to the side walls of the stop. The stops have a thickness extending outwardly from the exterior walls. The thickness of a stop may be 5 mm, or approximately 5 mm, or in the range of 3 mm to 10 mm, or in the range of approximately 3 mm to approximately 10 mm. The thickness of a stop should be sufficient to enable it to rest on the rim of the lower item in a stack, and it need not be any thicker. In particular, a stop need not be thick enough, and extend from the exterior wall far enough, to be functional as a handle. The stops are preferably solid and made of a rigid material that is oven-safe, for example, metal, steel, aluminum, titanium, ceramic or oven-safe polymer material. As an alternative to attaching a stop to the wall of a cookware item, the stop may be formed integrally with the wall of the item.

[0049] According to an aspect of the subject technology, preferably, the lower surface of a stop is adapted to contact the rim of the lower item in the stack at a limited number of contact points. For example, in the non-limiting embodiments of Figures 1-8, the lower surface of each stop 14 has two nibs or radii 21 at opposite ends of the stop, to contact the rim 12 of middle item 16 at exactly two contact points with respect to each stop. Thus, top item 11 contacts middle item 12 at exactly four points. Similarly, the lower surfaces of stops 15 are shaped to

2019201905 23 Mar 2020 in a stable configuration with other cookware as described herein, for example those shown in Figures 9-35. As shown in Figures 9-35, a single item of cookware 50 according to the subject technology has one or more stops 51 attached to a wall 52 of the item, the wall rising from base 53 to rim 54. In various embodiments, cookware 50 may have a straight handle 55 or loop handle 56, or both, attached between a stop, or stops, 51 and rim 54.

[0052] Generally, a stop for a stackable and nestable cookware item according to the subject technology may be in the form of a rectangular bar or badge, curved to fit the outer surface of the cookware item, having an inner surface which is entirely in contact with the wall to which it is attached, and having projections or nibs adapted to directly contact the rim of a lower cookware item at a finite number of points, for example, at one, two, three, or more points. For example, as shown in Figure 19, stop 51 has a lower edge having a non-linear profile which defines exactly two nibs, 102, 103. Stop 51 has left end 100 and a right end 101 spaced apart from left end 100. Nibs 102, 103 disposed and spaced apart on the left end 100 and the right end 101 respectively. As seen for example in Figure 3, stop 15 has nibs 20 formed at a right end and left end thereof. Stop 15 directly contacts rim 17 at two points, where nibs 20 directly contact rim 17. Between the points of direct contact, a gap (unnumbered) where there is no contact between stop 15 and rim 17 is defined between stop 15 and rim 17 at the top and bottom of the gap, and nibs 102, 103 at the left end and right end of the gap.

[0053] As shown in the non-limiting embodiments of Figures 38 and 39, exemplary shapes for the projections or nibs of a stop include a triangular or other polygonal shape which contacts the lower rim at a vertex of the polygon; or a part of a circle, oval, curve or other rounded shape having a radius which contacts the lower rim at a tangent point of the projection. Figure 38 shows examples of stops 30 having two projections 31 for

2019201905 23 Mar 2020 contacting the lower item at two contact points, while the exemplary stops 32 of Figure 38 have one projection 33 for contacting the lower item at one contact point. It will be understood that (unless a claim herein specifies otherwise) a stop may be of any shape that does not interfere with the stacking and nesting of the items, and can be stably attached to the cookware items, and contacts the lower rim at a finite number of points. Preferably the area of the stop-to-rim

10A

2019201905 19 Mar 2019 at a tangent point of the projection. Figure 38 shows examples of stops 30 having two projections 31 for contacting the lower item at two contact points, while the exemplary stops 32 of Figure 38 have one projection 33 for contacting the lower item at one contact point. It will be understood that (unless a claim herein specifies otherwise) a stop may be of any shape that does not interfere with the stacking and nesting of the items, and can be stably attached to the cookware items, and contacts the lower rim at a finite number of points. Preferably the area of the stop-to-rim contact points according to the present invention is minimized,

i.e. it is not an extended area along the entire bottom surface of an attachment to the wall of an item. In the case of a stop having two contact points, the distance between the contact points may be 45 mm, or approximately 45 mm, or 46 mm, or approximately 46 mm, or 47 mm, or approximately 47 mm or in the range of 40 mm to 50 mm. It will be understood that it is within the scope of subject technology that a stop may be shaped to contact the lower rim at more than exactly two points, but in an embodiment having multiple stops suitably placed on the cookware item, this is not necessary to achieve the desired stability.

[0054] To result in a stable stack of cookware items according to the subject technology, it is desirable for the following conditions to be achieved: (1) the stops of a nested cookware item contact the lower item’s rim at a finite number of points; (2) the contact points lie in the same plane; (3) the contact points are sufficiently distributed about the perimeter of the rim to support the nested cookware item without a significant tendency to pivot, rock, or shift about the contact points; (4)

2019201905 19 Mar 2019 the nested item and lower item are not contacting at any other points, i.e. the walls, rim, bases, and any attached handles of the items are not contacting.

[0055] Figures 38 and 39 show schematic representations of a cookware item 40 having a wall 41. First stop 42 and second stop 43 are attached to the wall 41, across a diameter of the wall 41. In the example of Figure 38, first and second stops 42, 43 have two projections 44 each, which together define four contact points 45. In the example of Figure 39, first stop 42 has two projections 44 and second stop 43 has one projection 44, which together define three contact points 45. Three points of stop-to-rim contact as in Figure 39 will, by definition, always lie in the same plane. In an embodiment in which four points of contact are utilized as in Figure 38, care must be taken in the selection of stops and their placement on the nested items that the points of stop-to-rim contact will lie substantially in the same plane. Preferably, the plane of the stop-to-rim contacts is parallel to the plane of the item’s base and also to the plane of the item’s rim, so the item is supported on the rim by the stops in a straightly upstanding position, which will minimize the chance of contact between the walls, rim, bases, and any attached handles of the items. In this manner the cookware items are stacked in a stable configuration as disclosed herein without interlocking of handles, stops, rims, or other elements of items in the stack.

[0056] According to the subject technology a handle may be attached to the wall and/or rim of a nested item. The handle may be positioned above a stop. Alternatively, a stop and a handle may be combined into a single part having both functions. However, it should be understood that a stop according to the subject technology need not be functional as a handle, for example, it may be relatively thin and not extend far enough from the wall of the cookware item to be of any practical use as a handle. It need only extend far enough from the wall to enable contact of its downward projection or projections with the rim of the lower item in the stack. In this aspect of the subject technology, the stop has a thickness such that it does not extend beyond the outer diameter of the lower cookware item, measured at the rim of the lower cookware item; or extends beyond it by less than 1 cm; or extends beyond it by less than 0.5 cm; or extends beyond it by less than 0.25 cm; or extends beyond it by less than 0.1 cm.

[0057] According to a further non-limiting embodiment of the subject technology, not shown in the Figures, a cookware item is provided with three stops attached to its outer surface, each of the three stops being configured to contact the rim of the lower item at exactly one point (e.g., having any of the shapes shown in Figure 39, for example). Preferably, the three stops are evenly spaced around sides of the cookware item. A handle or handles may be attached above one or more of the stops.

[0058] It will also be understood that the ornamental appearance of stackable cookware as shown and described is within the scope of the subject technology.

[0059] While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles. It will also be understood that the present invention includes any combination of the features and elements disclosed herein and any combination of

2019201905 19 Mar 2019 equivalent features. The exemplary embodiments shown herein are presented for the purposes of illustration only and are not meant to limit the scope of the invention.
