Abstract
A cookware assembly comprises a lid including an underside and a plurality of basting projections. The underside has a center and extending toward a perimeter of the lid. Each of the plurality of basting projections protrudes downwardly from the underside of the lid. Each of the plurality of basting projections includes an interior concave surface, an exterior concave surface, and a drip ridge. The interior concave surface extends downwardly away from the underside to form a bay adjacent to the interior concave surface. The drip ridge is formed along a border between the interior concave surface and the exterior surface and defines a vertex along the drip ridge. During use of the lid, condensate formed on the underside collects along the interior concave surface, which funnels the condensate to the vertex for droplet formation and release from a corresponding one of the plurality of basting projections.

DETAILED DESCRIPTION
(17) The following detailed description of the invention provides example embodiments and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention. Relational terms herein such a first, second, top, bottom, etc. may be used herein solely to distinguish one entity or action from another without necessarily requiring or implying an actual such relationship or order. In addition, as used herein, the term about or substantially apply to all numeric values or descriptive terms, respectively, and generally indicate a range of numbers or characteristics that one of skill n the art would consider equivalent to the recited values or terms, that is, having the same function or results.
(18) The current invention relates to a cookware lid with basting projections and a cookware assembly incorporating the cookware lid. In particular, the cookware lid includes a plurality of projections extending downwardly from an underside of the cookware lid. When the lid is placed on a cookware vessel and cooked with one or more moist articles contained therein, moisture vaporizes and rises to the underside of the cookware lid, where the vapor condenses into moisture. The configuration of the underside and/or the arrangement of the plurality of projections collects the condensate to the plurality of projections, which in turn gathers the collect condensate into droplets for release down to food maintained within the cookware vessel.
(19) In one embodiment, each of the plurality of projections is configured to collect condensate from either side thereof and funnel the condensate into a discrete droplet release point at a vertex of each projection. In one example, the plurality of projections are spaced from one another such that the drops are distributed substantially evenly over an area below the underside of the lid and, therefore, over the food and liquid cooking in that area. In this manner, collected moisture is re-released to the cooking items in a distributed manner, not just at edges thereof, continuously and more evening basting the cooking item below
(20) Turning to the figures,
(21) Additionally referring to the bottom perspective view of
(22) Sidewall 32 extends downwardly from perimeter 40 of primary portion 30 to a sidewall edge 42. During use with vessel 12, sidewall edge 42 interfaces with vessel 12 near a top edge 44 of vessel 12 in a manner configured to maintain heat and moisture within chamber 24 during use of cookware assembly 10. In one example, lid 14 additionally includes one or more handle 46, such as a knob-type handle 46 extending upwardly from center 38 of lid 14 and/or side extending handles (not shown) extending radially outwardly from sidewall 32 of lid 14. Handle 46 may be integrally formed as a single piece with a remainder of lid 14 or formed separated and secured to a remainder of handle 46.
(23) Lid 14 includes a plurality of basting projections 50 or other self-basting features spaced from each other and each extending downwardly from underside 36 of lid 14. In one example, each basting projection 50 is formed as a peaked three-dimensional shape. Each basting projection 50 is configured to receive moisture condensation from liquid 28 and/or food item 26 in chamber 24 of vessel 12, as generally indicated by arrow 54 in
(24) Each basting projection 50 includes a center facing or interior surface 52 and a perimeter-facing or exterior surface 60 opposite interior surface 52. As illustrated with additional reference to the detailed view of
(25) In one example, each basting projection 50 further includes a perimeter-facing or exterior surface 60 opposite interior surface 52. Each exterior surface 60 intersects underside 36 along a top exterior line 64 and extends downwardly therefrom. Top exterior line 64 is curvilinear, for example, bowing toward perimeter with a substantially parabolic shape having a greater degree of curvature than top interior line 62. Exterior surface 60 is generally convex bowing toward perimeter 40. In one example, the convex nature of exterior surface 60 serves to prevent or at least decrease the amount of condensate from moving up exterior surface 60 even when lid 14 is moved or tilted. In one embodiment, top interior line 62 and top exterior line 64 intersect at opposing ends 66 and 68 thereof, which in one example, are each located along a common circumference or circular ring C.sub.A, C.sub.B, C.sub.C, or C.sub.D as shown in the simplified view of
(26) Each of interior surface 52 and exterior surface 60 extend from the corresponding one of top interior line 62 or top exterior line 64 to border or intersect each other along a drip line or ridge 70 also referred to a drip edge. In one embodiment, drip ridge 70 has a parabolic shape extending progressively further away from underside 36 as drip ridge 70 extends away from opposing ends 66 and 68. According to one example, drip ridge 70 defines a peak or vertex 72, which serves as a discrete droplet release point, at the lowermost point of drip ridge, that is at the farthest point of drip ridge 70 away from underside 36. In general, the center cross-sectional shape of each basting projection 50 decreases or tapers in depth as the basting projection 50 extends from underside 36 to f 72. In one example, each basting projection 50 is substantially symmetrical about a mid-line (not shown) that intersects vertex 72 about half way between opposing ends 66 and 68 such that condensate from both sides of vertex 72 are collected and moved toward vertex 72 due to gravitational forces and design of lid 14. In this manner, vertex 72 is substantially centered along drip ridge 70 between opposing ends 66 and 68. In one embodiment, basting projection 50 is solid between interior surface 52 and exterior surface 60 and between underside 36 and vertex 72.
(27) In view of the example basting projection 50 with a cupped shape of bay 74 as described above, each basting projection 50 is configured to collect moisture along interior surface 52 thereof, for instance, within bay 74, and to redirect said moisture back into chamber 24 of vessel 12. More specifically, additionally referring to
(28) In turn, via the continued influence of gravitational forces, moisture in bay 74 slides along interior surface 52 of basting projection 50 to vertex 72. The moisture continues to collect along interior surface 52 and, more specifically, vertex 72, forming a moisture droplet 58 due to surface tension between the moisture molecules. As the moisture continues to collect, a size of moisture droplet 58 grows until moisture droplet 58 has a sufficient weight to overcome any surface tension previously holding moisture droplet 58 to basting projection 50. When the surface tension is counteracted, moisture droplet 58 is released from basting projection at vertex 72, dropping substantially vertically back down to food item 26 and/or liquid 28 maintained in vessel 12 immediately below, as generally indicated by moisture arrows 56 in
(29) In order to collect moisture from underside 36 in a consistent manner and to release moisture droplets 58 back to food item 26 and liquid 28 below in an evenly distributed manner for more even and consistent braising of food item 26 below, in one embodiment, the plurality of basting projections 50 are arranged in a plurality of concentrically positioned circular arrays all having similarly shaped, but differently sized basting projections 50. As illustrated, for example, with reference to
(30) For instance, an innermost circular array of basting projections 50A is formed around a first circular ring C.sub.A concentrically positioned around a center of lid 14 spaced from perimeter 40. Opposing ends 66 and 68 of each basting projection 50A in the innermost circular array is positioned substantially directly on first circular ring C.sub.A. Additionally referring to
(31) The second circular array includes basting projections 50B, which are formed in a similar cupped shaped as basting projections 50A other than differences specifically described herein. Basting projections 50B face center 38 of lid and are circumferentially spaced and formed around a second circular ring C.sub.B, where second circular ring C.sub.B is concentric relative to and larger than first ring C.sub.A. In one embodiment, a diameter of ring C.sub.B is about 150% the size of a diameter of circular ring C.sub.A, while other size increases are also contemplated. For example, second circular ring C.sub.B has a diameter of between about 100 mm and about 106 mm, while first circular ring C.sub.A has a diameter of about 68 mm. In one embodiment, the larger the increase in size between adjacent circular rings C.sub.A, C.sub.B, C.sub.A, and/or C.sub.D, the larger the increase in widths of the corresponding basting projections 50A, 50B, 50C, and/or 50D, as further described below, to accommodate the larger surface area of underside 36 collecting condensate between the adjacent ones of circular rings C.sub.A, C.sub.B, C.sub.A, and/or C.sub.D.
(32) In one embodiment, the height H (
(33) Additionally referring to
(34) In one example, a number of basting projections 50A is less than or the same as a number of basting projections 50B, with each of basting projections 50B being positioned on a radial line between, for example, about half way between, two adjacent basting projections 50A, that is, circumferentially centered between two adjacent basting projections 50A. In this manner, as illustrated with reference to
(35) In a similar manner as described for basting projections 50A and 50B above, additional circular arrays of basting projections 50C and 50D are formed along additional circular rings C.sub.C and C.sub.D on underside 36 of lid 14 with each circular ring C.sub.C and C.sub.D increasing in size as they move from center 38 of lid 14 to perimeter 40 of lid 14. One example of a spacing of circular rings C.sub.A, C.sub.B, C.sub.C, and C.sub.D is illustrated in
(36) In one embodiment, additionally concentric circular arrays of basting projections are formed on increasingly larger and concentric circular rings C.sub.C and C.sub.D, more specifically, including basting projections 50C and 50D, respectively. With each increasingly larger circular ring C.sub.C and C.sub.D, the basting projections 50C and 50D, which are otherwise substantially identical to basting projections 50A and 50B, also increase in width. In this example, a width W.sub.C of individual basting projections 50C is larger than widths W.sub.A and W.sub.B of individual basting projections 50A and 50B, respectively, but is smaller than a width W.sub.D of an individual basting projection 50D to continue to accommodate increased condensate along underside 36 as underside 36 nears perimeter 40 of lid 14. In one example, a number of basting projections 50C is the same as or greater than the number of basting projections 50B or basting projections 50A, and a number of basting projections 50D is the same as or greater than the number of basting projections 50C. In one embodiment, the number of basting projections 50D is greater than the number of basting projections 50C such that part or all of more than one basting projection 50D are positioned between each set of adjacent basting projections 50C.
(37) Depending upon the overall size of lid 14, the number of circular arrays of basting projections 50, the number of basting projections 50 in each array, and the spacing of basting projections 50 in each array will vary as illustrated, for example, when viewing
(38) While any condensate captured outside of circular ring C.sub.D will likely move to chamber 24 of vessel 12 along sidewall 22 thereof, the other condensate captured in one of basting projections 50 will eventually fall from vertices 72 as droplets 100 in a substantially evenly spaced manner as shown in
(39) While cookware assembly 10 as described above provides embodiments of the present invention, other variations are also contemplated. For instance, one embodiment of cookware assembly 110, as illustrated in
(40) Although the invention has been described with respect to particular embodiments, such embodiments are meant for illustrative purposes only and should not be considered to limit the invention. Various alternatives and changes will be apparent to those of ordinary skill in the art upon reading this application, including the shape or number of basting projections, number or spacing of circular arrays, etc. Other modifications within the scope of the invention and its various embodiments will be apparent to those of ordinary skill.
