Description
Background of the Invention
1. Field of the Invention
The present invention generally relates to cookware and, more particularly, is concerned with an overflow pan assembly with a splashguard cap and cap positioning means.
2. Description of the Prior Art
Pans with lids or covers are typically employed on stoves to cook food and boil water for any number of uses. Liquid contained in pans frequently overflows due to inattention as the temperature of the liquid rises and as vapor pressure increases under the lids on the pans. Various pans with lids have been developed over the years toward resolving this and other problems. Representative examples of prior art pans with lids are disclosed in U.S. Pat. No. 504,243 to Philippot, U.S. Pat. No. 1,461,366 to Mulford et al., U.S. Pat. No. 1,676,146 to Krafft, U.S. Pat. No. 1,810,860 to Tremblay, U.S. Pat. No. 2,127,988 to Tarrant, U.S. Pat. No. 2,385,594 to Witte, Jr., U.S. Pat. No. 5,033,453 to Loyd et al., U.S. Pat. No. 5,193,524 to Loyd et al., Danish Pat. No. 26,919 to Holm and German Pat. No. 696,673 to Boecker. While these prior art pans with lids appear to be satisfactory in use for the specific purposes for which they were designed, none of them seem to provide a comprehensive and effective solution to prevent liquid overflow.
Consequently, a need still exists for an assembly which provides an optimum solution to the aforementioned problem in the prior art without introducing any new problems in place thereof.
Summary of the Invention
The present invention provides an overflow pan assembly designed to satisfy the aforementioned need. The overflow pan assembly of the present invention provides a pan with a cap forming an upper catch chamber outside the cap which receives and directs overflow liquid from the exterior of the cap back into the lower cooking chamber of the pan through an equalizing gap formed between the cap and pan when the cap is placed in an elevated opened position relative to the pan. The overflow pan assembly thus solves the aforementioned problem of the prior art by preventing liquid from overflowing the pan when unattended by the user. The overflow pan assembly also includes cap positioning means which at least partially elevates the cap relative to the pan and thereby form at least a portion of the equalizing gap between the cap and pan.
Accordingly, the present invention is directed to an overflow pan assembly which comprises: (a) a pan including (i) a bottom wall having a periphery, (ii) a lower side wall having an annular shape, an upper end of a first diameter, and a lower end connected to and extending upwardly from the periphery of the bottom wall such that the lower side wall and bottom wall of the pan form a lower cooking chamber, (iii) an upper side wall having an annular shape, an upper end and a lower end of a second diameter greater than the first diameter of the upper end of the lower side wall, and (iv) a ledge having an annular shape extending between and interconnecting the upper end of the lower side wall and the lower end of the upper side wall, the upper side wall and ledge of the pan forming an upper reservoir chamber of the pan above the lower cooking chamber thereof; (b) a cap including (i) a top wall having a periphery, and (ii) a side wall having an annular shape, an upper end connected to and extending downwardly from the periphery of the top wall such that the side wall and top wall of the cap form an inner splash chamber within the cap and above the lower cooking chamber and intersecting with the upper reservoir chamber of the pan, the side wall of the cap also having a lower end of a third diameter greater than the first diameter of the upper end of the lower side wall of the pan and less than the second diameter of the lower end of the upper side wall of the pan, the side wall of the cap and the upper side wall and ledge of the pan forming an outer catch chamber outside the cap and within the upper reservoir chamber of the pan; and (c) cap positioning means defined on at least one of the ledge of the pan and the lower end of the side wall of the cap for disposing at least a portion of the cap spaced above the ledge of the pan so as to thereby form a passage between the ledge of the pan and lower end of the side wall of the cap whereby fluid is allowed to pass through the passage between the lower cooking chamber and outer catch chamber.
More particularly, several different embodiments of the cap positioning means are disclosed. In a first embodiment, the cap positioning means includes at least one protuberance formed on and protruding upwardly from the ledge of the pan so as to hold at least a portion of the lower end of the side wall of the cap in a spaced relationship above the ledge of the pan and thereby provide the passage therebetween. In a second embodiment, the cap positioning means includes at least one undulation formed on the lower end of the side wall of the cap so as to provide at least a portion of the lower end of the side wall of the cap in a spaced relationship above the ledge of the pan and thereby provide the passage therebetween. In a third embodiment, the cap positioning means includes at least one protuberance formed on and protruding upwardly from the ledge of the pan and at least one recess formed on the lower end of the side wall of the cap and complementary in shape to and mateable with and unmateable from the at least one protuberance such that when the at least one recess and at least one protuberance are unmated and circumferentially displaced from one another the at least one protuberance holds at least a portion of the lower end of the side wall of the cap in a spaced relationship above the ledge of the pan and thereby provides the passage therebetween whereas when the at least one recess and at least one protuberance are aligned and mated with one another the lower end of the side wall of the cap rests on the ledge of the pan and substantially closes the passage therebetween.
These and other features and advantages of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings wherein there is shown and described an illustrative embodiment of the invention.

Detailed Description of the Invention
Referring to the drawings and particularly to FIG. 1, there is illustrated an overflow pan assembly, generally designated 10, of the present invention. The overflow pan assembly 10 basically includes a pan 12, a cap 14 and a positioning means 16. The cap 14 may be placed on and removed from the pan 12. The positioning means 16 is adapted to dispose the cap 14 at either one of an opened position, seen in solid line form at A in FIG. 2, and a closed position, seen in dashed line form at B in FIG. 2, relative to the pan 12.
Referring now to FIGS. 1 to 3, the pan 12 of the assembly 10 has a bottom wall 18, a lower side wall 20, an upper side wall 22, and a ledge 24. The bottom wall 18 of the pan 12 has a substantially flat circular configuration. The lower side wall 20 of the pan 12 has a substantially annular shape and a continuous upper end 20A and a continuous lower end 20B. The lower side wall 20 diverges slightly from the lower end 20B, adjacent to the bottom wall 18, to the upper end 20A, adjacent to the ledge 24. The diameter at the upper end 20A of the lower side wall 20 is slightly greater than the diameter at the lower end 20B thereof. Preferably, the upper and lower ends 20A, 20B are rounded with the curvature of the upper end 20A being in a direction opposite to the direction of the curvature of the lower end 20B. The lower side wall 20 at its lower end 20B is connected to the periphery of the bottom wall 18 and extends upwardly therefrom such that the bottom wall 18 and lower side wall 20 together form a lower cooking chamber 26 of the pan 12.
The upper side wall 22 of the pan 12 has a substantially annular shape and a continuous upper end 22A and a continuous lower end 22B. The upper side wall 22 diverges slightly from the lower end 22B, adjacent to the ledge 24, to the upper end 22A. The upper side wall 22 also has a diameter at the upper end 22A which is slightly greater than the diameter at the lower end 22B of the upper side wall 22. The lower end 22B of the upper side wall 22 is rounded and merges into the outer diameter of the ledge 24 while the upper end 22A provides a top rim of the pan 12. The lower end 22B of the upper side wall 22 has a curvature opposite to that of the upper end 20A of the lower side wall 20. The lower and upper side walls 20, 22 of the pan 12 are disposed in vertically offset but approximately parallel relation to one another. The lower side wall 20 has a height greater than that of the upper side wall 22.
The ledge 24 of the pan 12 extends between and merges into and thus interconnects the upper end 20A of the lower side wall 20 and the lower end 22B of the upper side wall 22. The ledge 24 has a generally continuous annular shape and is inclined outwardly rising slightly from the upper end 20A of the lower side wall 20 to the lower end 22B of the upper side wall 22. The upper side wall 22 and ledge 24 of the pan 12 together form an upper reservoir chamber 28 of the pan 12 above the lower cooking chamber 26 thereof. The upper reservoir chamber 28 has a capacity approximately equal to the capacity of the lower cooking chamber 26 which serves to control any overflow when the cap 14 is removed from the pan 12 and the cooking contents are being stirred.
The cap 14 of the assembly 10 has a top wall 30 and a side wall 32. The top wall 30 has a substantially circular configuration and can be relatively flat or dome-shaped as desired. The side wall 32 has a substantially annular shape and a continuous upper end 32A and a continuous lower end 32B. The side wall 32 at its upper end 32A is connected to the periphery of the top wall 30 and extends downwardly therefrom such that the top wall 30 and side wall 32 together form an inner splash chamber 34 within the cap 14 and above the lower cooking chamber 26 of the pan 12 and also intersecting with the upper reservoir chamber 28 of the pan 12. The side wall 32 diverges slightly from the upper end 32A, adjacent to the top wall 30, to the lower end 32B. The diameter at the lower end 32B of the side wall 32 is slightly greater than the diameter at the upper end 32A thereof. The diameter at the upper end 32A of the side wall 32 of the cap 14 is approximately the same as the diameter of the upper end 20A of the lower side wall 20 of the pan 12. The upper end 32A of the side wall 32 is rounded where it merges from the top wall 30 of the cap 14. The lower end 32B of the side wall 32 provides a bottom rim on the cap 14. The diameter of the lower end 32B of the side wall 32 of the cap 14 is greater than the diameter of the top end 20A of the lower side wall 20 of the pan 12 but is less than the diameter of the lower end 22B of the upper side wall 22 of the pan 12 whereby the bottom rim of the cap 14 can be disposed generally centrally about and above the ledge 24 of the pan 12. The height of the side wall 32 of the cap 14 preferably is similar to the height of the pan 12.
When placed on the pan 12 as seen in FIG. 2, the cap 14 is disposed partially within the upper reservoir chamber 28 of the pan 12. As mentioned above, the top wall 30 and side wall 32 of the cap 14 form the inner splash chamber 34 inside the cap 14 above the lower cooking chamber 26 of the pan 12. The side wall 32 of the cap 14 and the upper side wall 22 and ledge 24 of the pan 12 together form an outer catch chamber 36 outside the cap 14 and within the upper reservoir chamber 28 of the pan 12.
Referring now to FIGS. 1 to 4, the positioning means 16 facilitates placement of the cap 14 at either one of the opened position and closed position as represented by the lower end 32B of the cap 14 being disposed either at position A or position B shown in FIG. 2. When the cap 14 is in the opened position, the lower end 32B of the side wall 32 of the cap 14 is elevated above and prevented from contacting the ledge 24 of the pan 12 and thereby provides an equalizing gap 38 between the lower end 32B of the side wall 32 of the cap 14 and the ledge 24 of the pan 12 such that liquid may pass through the gap 38 into and from the inner splash chamber 34 of the cap 14 and into and from the outer catch chamber 36 of the cap 14 and the pan 12. In view that the lower end 32B of the side wall 32 of the cap 14 is elevated above the ledge 24 but still submerged in liquid on both sides, a liquid seal is provided through the gap 38 which prevents froth and boiling activity in the inner splash chamber 34 from affecting liquid in the outer catch chamber 36. Thus, the lower cooking chamber 26 is covered and all activity due to boiling surfaces remains within the inner splash chamber 34. When the cap 14 is in the closed position, the lower end 32B of the side wall 32 of the cap 14 rests on the ledge 24 of the pan 12 and thereby closes the gap 38 between the lower end 32B of the side wall 32 of the cap 14 and the ledge 24 of the pan 12 such that liquid is prevented from passing through the gap 38.
More particularly, the positioning means 16 preferably is in the form of a pair of first handles 40 mounted to the pan 12 and a pair of second handles 42 mounted to the cap 14. The first handles 40 are mounted to the upper side wall 22 of the pan 12 substantially opposite from one another and adjacent to and extending outwardly from the upper end 22A of the upper side wall 22. Each first handle 40 extends farther outwardly from the upper side wall 22 than above the upper side wall 22 and, as an example, has a substantially J-shaped configuration in cross-section and an outer portion 40A and an inner portion 40B. The outer portion 40A of each first handle 40 extends outwardly from the upper side wall 22 while the inner portion 40B thereof extends along the upper side wall 22. Each first handle 40 has a substantially uniform width along the outer and inner portions 40A, 40B thereof and a substantially rectangular configuration when viewed from above. Each first handle 40 is mounted to the upper side wall 22 of the pan 12 by any suitable means, such as by screw fasteners (not shown).
The second handles 42 are mounted to the side wall 32 of the cap 14 substantially opposite from one another and between and spaced from the upper and lower ends 32A, 32B of the side wall 32 and extend outwardly from the side wall 32. Each second handle 42, as an example, has a substantially J-shaped configuration in cross-section and an outer portion 42A and an inner portion 42B. The outer portion 42A of each second handle 42 extends outwardly from the side wall 32 while the inner portion 42B of each second handle 42 extends along the side wall 32. The outer portion 42A of each second handle 42 has a length substantially greater than the length of the inner portion 42B thereof and of the length of the outer portion 40B of each first handle 40 such that the second handles 42 are easy to grasp by the user. Each second handle 42 has a substantially uniform width along the outer and inner portions 42A, 42B thereof. The width of each second handle 42 of the cap 14 also is greater than the width of each first handle 40 of the pan 12, as shown in FIGS. 3 and 4. Each second handle 42 has a substantially rectangular configuration when viewed from above. Each second handle 42 is mounted to the side wall 32 of the cap 14 by any suitable means, such as by screw fasteners (not shown).
Each second handle 42 of the cap 14 is pairable with and restable upon one of the first handles 40 of the pan 12 such that the resting of the second handles 42 upon the first handles 40 retains the cap 14 in the open position hanging by its pair of second handles 42 over the pan 12 with its splash chamber 34 rising above all possible liquid levels. The second handles 42 of the cap 14 are separable from the first handles 40 of the pan 12 to place the cap 14 in the closed position. In the closed position, the cap 14 sits with its lower end 32B resting on the ledge 24 of the pan 12. In this position, the cap 14 acts as a lid that can either be closed or vented as described below. The substantially J-shaped cross-sectional configuration of each second handle 42 allows for centering of the cap 14 relative to the ledge 24 of the pan 12. This centering of the cap 14 relative to the ledge 24 of the pan 12 is accomplished when the outer portions 42A of the second handles 42 are resting flush on the outer portions 40A of the first handles 40. The J-shaped configuration of each second handle 42 causes both sides of the cap 14 to rise when the outer portions 42A of the second handles 42 are not resting flush on the outer portions 40A of the first handles 40.
The first and second handles 40, 42 also can have complementary first and second detent means 44, 46 formed thereon which are interfittable or mateable with one another when the second handles 42 are resting on the first handles 40 for easier achievement and retention of the centering of the cap 14 over the pan 12 relative to the annular ledge 24 of the pan 12. The first and second detent means 44, 46 preferably take the form of complementary paired recesses 44 and protrusions 46 formed on the first and second handles 40, 42 so as to face toward and align and interfit with each other when the second handles 42 are resting on the first handles 40. Each protrusion 46 has a center portion 46A which fits into one of the recesses 44 and a pair of opposite end portions 46B which extend in transverse relationship to the center portion 46A and fit along opposite sides of the respective second handle 42 adjacent to the opposite ends of the respective recess 44. The center and opposite end portions 46A, 46B, which along their respective lengths lie in orthogonal relationship to one another, prevent horizontal movement of the cap 14 in any direction relative to the pan 12 and hold the cap 14 in an exactly dead centered alignment over the pan 12.
The second handles 42 have top surfaces 42C with portions thereof adjacent to where the second handles 42 are mounted to the exterior of the side wall 32 of the cap 14 having depressions 48 so as to direct liquid traveling down an exterior surface 14A of the cap 14 into the outer catch chamber 36 instead of allowing the liquid to travel outwardly along the exterior surfaces 42C of the second handles 42. Also, optionally, each second handle 42 can have a bead 50 formed on the top surface 42C along an edge of the depression 48 opposite from the side wall 32 of the cap 14 which serves as a further barrier to liquid traveling outwardly from the cap 14 on the top surface 42C of the second handle 42.
The cap 14 of the assembly 10 also has one or more and, preferably, four vent holes 52 defined in the top wall 30 of the cap 14. The vent holes 52 are spaced apart an equal distance from one another. By way of example, each vent hole 52 can have a substantially triangular configuration, as shown, or may have any other suitable configuration. The assembly 10 further comprises a vent closure member 54. The vent closure member 54 has a generally circular configuration and is rotatably mounted at the center thereof to the center of the top wall 30 of the cap 14 and is disposed below the top wall 30 of the cap 14 within the inner splash chamber 34 of the cap 14. The vent closure member 54 defines one or more and, preferably, four vent apertures 56. The vent apertures 56 are spaced apart an equal distance from one another and can have any desired shape. By way of example, each vent aperture 56 has a substantially triangular configuration. The vent apertures 56 of the vent closure member 54 have sizes and spacing substantially the same as the vent holes 52 of the cap 14. The cap 14 also has a central hole 58 defined in the top wall 30 of the cap 14 and a fastener assembly 60 releasably mounting the vent closure member 54 to the top wall 30 of the cap 14. Further still, the vent closure member 54 has a lever 62 mounted thereon and extending through the top wall 30 of the cap 14 for allowing a user to grasp the lever 62 to rotate the vent closure member 54. The lever 62 is a finger-tip type.
The vent closure member 54 is rotatable such that the vent holes 52 of the cap 14 may be closed and open to varying degrees by the vent apertures 56 of the vent closure member 54 being moved away from and toward alignment with the vent holes 52 of the cap 14. The overlapping of the vent holes 52 and vent apertures 56 allows for passage of steam therethrough from the inner splash chamber 34 of the cap 14 to the exterior surface 14A of the cap 14 and the external environment. The outer catch chamber 36 is always open to the external environment. The combination of open vent holes 52 of the cap 14 and the open outer catch chamber 36 enables the assembly 10 to relieve steam pressure and reduce the amount of fluid overflow. The inner splash chamber 34 of the cap 14 extends to a height above the lower cooking chamber 26 of the pan 12 sufficient to provide adequate room for foam or froth control. Froth from liquid boiling in the lower cooking chamber 26 of the pan 12 that elevates sufficiently within the inner splash chamber 34 may pass through the aligned vent holes and apertures 52, 56 of the cap 14 and vent closure member 54 and condense on an exterior surface 14A of the cap 14 and run as liquid back down and into the outer catch chamber 36 and reenter the lower cooking chamber 26 via the equalizing gap 38 therebetween. This condensation enables the assembly 10 to held maintain liquid in the lower cooking chamber 26 of the pan 12 and to reduce the instances of overflow of the pan 12 and of boiling the pan dry. Furthermore, when cooking foods that require it, the extra capacity of the outer catch chamber 36 provides the opportunity for a user to add extra water without removing the cap 14 by simply pouring the water into the outer catch chamber 36. The outer catch chamber 36 will funnel the water into the lower cooking chamber 26 via the equalizing gap 38. The pan 12 also has a spout 64 defined on the top edge 22A of the upper side wall 22 of the pan 12. The spout 64 is a pitcher-type. The spout 64 is located halfway between the first handles 40 of the pan 12.
To recapitulate, when the cap 14 is in the opened hanging position, it divides the upper reservoir chamber 28 of the pan 12 into the inner splash chamber 34 and outer catch chamber 36 united by a liquid seal at the gap 38 through which liquid is free to flow and seek its own level. Also, steam can be vented as it is generated, eliminating steam pressure problems within the splash chamber 34. The outer catch chamber 36 remains unaffected by the activity taking place within the splash chamber 34. All expelled froth and liquid are caught in the catch chamber 36 and returned to the cooking chamber 26 as the liquid seeks its own level by passing through the equalizing gap 38. Another advantage is that liquid can be added to the cooking chamber 26 without removing the cap 14 simply by pouring it into the outer catch chamber 36. This eliminates the need to remove a dripping cap 14 in order to replenish liquid to the cooking chamber 26. The second handles 42 of the cap 14 are slightly longer than the first handles 40 of the pan 12 to make lifting or adjustment easier. As the cap 14 is removed from the pan 12, the upper reservoir chamber 28 is formed. This chamber 28 has approximately the same volume capacity as the lower cooking chamber 26, but has approximately two and one-quarter times greater surface area. When cooking volatile foods that need to be stirred constantly, these capabilities become invaluable. As frothy contents of the cooking chamber 26 expand, the space to contain and control them, plus the greater exposure to atmospheric cooling to quiet them, is provided in the upper reservoir chamber 28. Further, to drain excess liquid after cooking, the user's hands are placed to either side of the rising steam and the weight of the assembly 10 is evenly distributed by the handles 40, 42. Liquid drains freely through the gap 38 while the cap 14 is held firmly in place with both hands as all food is retained in the cooking chamber 26. Liquid is consolidated into a stream by the pitcher spout 64 eliminating drips during the draining process.
Referring now to FIGS. 5 to 8, there are illustrated three different embodiments of a cap positioning means, generally designated 66 in FIG. 5, 68 in FIG. 6 and 70 in FIGS. 7 and 8. Any one of the cap positioning means 66, 68, 70 can be provided in the assembly 10 along with the above-described positioning means 16 or can be provided in the assembly 10 alone as an alternative to the positioning means 16.
In the first embodiment shown in FIG. 5, the cap positioning means 66 is at least one and preferably a plurality of protuberances 72 formed on and protruding upwardly from the ledge 24 of the pan 12 so as to hold at least a portion of the lower end 32B of the side wall 32 of the cap 14 in a spaced relationship above the ledge 24 of the pan 12 and thereby provide a passage 74 therebetween. The purpose of including the first embodiment of the cap positioning means 66 in the assembly 10 either alone or in conjunction with the above-described positioning means 16 is to ensure that the cap 14 will never completely rest on the ledge 24 of the pan 12 thus the equalizing gap 38 will never be entirely closed in view that the passage 74 provided by the protuberances 72 is always present between the cap 14 and pan 12. While only one protuberance 72 will serve this purpose, the provision at least two spaced apart protuberances 72 is preferred in order to reduce or eliminate the ability of the cap 14 to rock relative to the pan 12.
In the second embodiment shown in FIG. 6, the cap positioning means 68 is at least one and preferably a plurality of recesses or undulations 76 formed on the lower end 32B of the side wall 32 of the cap 14 so as to provide at least a portion of the lower end 32B of the side wall 32 of the cap 14 in a spaced relationship above the ledge 24 of the pan 12 and thereby provide a passage 78 therebetween. The purpose of including the second embodiment in the assembly 10 is the same as that mentioned above for the first embodiment.
In the third embodiment shown in FIGS. 7 and 8, the cap positioning means 70 includes at least one and preferably a plurality of protuberances 80 formed on and protruding upwardly from the ledge 24 of the pan 12 and at least one and preferably a like plurality of recesses or undulations 82 formed on the lower end 32B of the side wall 32 of the cap 14 and being complementary in shape to and mateable with and unmateable from the protuberances 80 such that when the recesses or undulations 82 and protuberances 80 are unmated and displaced from one another, as seen in FIG. 7, the protuberances hold at least a portion of the lower end 32B of the side wall 32 of the cap 14 in a spaced relationship above the ledge 24 of the pan 12 and thereby provides the equalizing gap 38 therebetween. On the other hand, when the recesses or undulations 82 and protuberances 80 are aligned and mated with one another, as seen in FIG. 8, the lower end 32B of the side wall 32 of the cap 14 entirely rests on the ledge 24 of the pan 12 and substantially closes the equalizing gap 38 therebetween. The purpose of including the third embodiment of the cap positioning means 66 in the assembly 10 either alone or in conjunction with the above-described positioning means 16 is to provide the option of either allowing the cap 14 to completely rest on the ledge 24 of the pan 12 thus close the equalizing gap 38 or providing the cap 14 partially open relative to the pan 12 so that the equalizing gap 38 is not entirely closed. While only one protuberance 80 and one undulation 82 will serve this purpose, the provision at least two of each is preferred in order to reduce or eliminate the ability of the cap 14 to rock relative to the pan 12.
It is thought that the present invention and its advantages will be understood from the foregoing description and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely preferred or exemplary embodiment thereof.
Claims
We claim:
1. An overflow pan assembly, comprising: (a) a pan including (i) a bottom wall having a periphery, (ii) a lower side wall having a substantially annular shape, an upper end of a first diameter, and a lower end connected to and extending upwardly from said periphery of said bottom wall such that said bottom wall and lower side wall of said pan form a lower cooking chamber of said pan, (iii) an upper side wall having a substantially annular shape, an upper end and a lower end of a second diameter greater than said first diameter of said upper end of said lower side wall, and (iv) a ledge having a substantially annular shape extending between and interconnecting said upper end of said lower side wall and said lower end of said upper side wall, said upper side wall and ledge of said pan forming an upper reservoir chamber of said pan above said lower cooking chamber thereof; (b) a cap including (i) a top wall having a periphery, and (ii) a side wall having a substantially annular shape, an upper end connected to and extending downwardly from said periphery of said top wall such that said side wall and top wall of said cap form an inner splash chamber within said cap and above said lower cooking chamber of said pan and intersecting with said upper reservoir chamber of said pan, said side wall of said cap also having a lower end of a third diameter greater than said first diameter of said upper end of said lower side wall of said pan and less than said second diameter of said lower end of said upper side wall of said pan, said side wall of said cap and said upper side wall and ledge of said pan forming an outer catch chamber outside said cap and within said upper reservoir chamber of said pan; and (c) cap positioning means defined on at least one of said ledge of said pan and said lower end of said side wall of said cap for disposing at least a portion of said cap spaced above said ledge of said pan so as to thereby form a passage between said ledge of said pan and lower end of said side wall of said cap whereby fluid is allowed to pass through said passage between said lower cooking chamber and outer catch chamber.
2. The assembly of claim 1 wherein said cap positioning means includes at least one protuberance formed on and protruding upwardly from said ledge of said pan so as to hold at least a portion of said lower end of said side wall of said cap in a spaced relationship above said ledge of said pan and thereby provide said passage therebetween.
3. The assembly of claim 2 wherein said cap positioning means includes a plurality of said protuberances.
4. The assembly of claim 1 wherein said cap positioning means includes at least one undulation formed on said lower end of said side wall of said cap so as to provide at least a portion of said lower end of said side wall of said cap in a spaced relationship above said ledge of said pan and thereby provide said passage therebetween.
5. The assembly of claim 1 wherein said cap positioning means includes a plurality of said undulations.
6. The assembly of claim 1 wherein said cap positioning means includes at least one protuberance formed on and protruding upwardly from said ledge of said pan and at least one recess formed on said lower end of said side wall of said cap and complementary in shape to and mateable with and unmateable from said at least one protuberance such that when said at least one recess and at least one protuberance are unmated and displaced from one another said at least one protuberance holds at least a portion of said lower end of said side wall of said cap in a spaced relationship above said ledge of said pan and thereby provides said passage therebetween whereas when said at least one recess and at least one protuberance are aligned and mated with one another said lower end of said side wall of said cap rests on said ledge of said pan and substantially closes said passage therebetween.
7. The assembly of claim 6 wherein said cap positioning means includes like pluralities of said protuberances and said recesses.
