DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws to promote the progress of science and useful arts (Article 1, Section 8).

(9) An axially collapsible cooking vessel is generally indicated by numeral 10 in the Figures, and provides a flexible body 20, a removable lid 40 a heat conductive base 60, and a heatsink 80.

(10) The flexible body 20, as seen in the Figures, has a general configuration of a truncated cone with an outer circumferentially extending surface 21, an opposing inner circumferentially extending surface 22, an upper peripheral edge 23 defining an upper diameter 24, and a bottom edge 25 defining a bottom diameter 26. The body 20 defines an interior volume 28 surrounded by the inner circumferentially surface 22 between the upper peripheral edge 23 and the bottom edge 25, and further has a height dimension 32 extending between the upper peripheral edge 23 and the bottom edge 24. An internal support ring 29 may be integrally carried within the flexible body 20 proximate the upper peripheral edge 23. An annular ring 30 may be carried adjacent the upper peripheral edge 23 extending about the outer circumferential surface 21. The annular ring 30 provides plural spacedly arrayed protuberances 31 to provide for attachment of the removable lid 40. Further, the annular ring 30 may carry handles (not shown) to facilitate handling of the cooking vessel 10.

(11) In the preferred embodiment, the flexible body 20 is formed of a flexible resiliently deformable polymer, such as, but not limited, to silicone, or thermal plastic urethane (TPU) or thermal plastic rubber (TPR). The flexible body 20 defines at least one and preferably plural circumferentially extending areas 27 having a reduced thickness. The reduced thickness areas 27 extend circumferentially about the flexible body 20 and are spacedly arrayed thereon. The reduced thickness areas 27 allow the flexible body 20 to form a flexible internally nestable wall wherein the flexible body 20 folds axially inwardly and downwardly upon itself about the reduced thickness areas 27 to reduce the height dimension 32 (See FIGS. 2 and 3) of the flexible body 20.

(12) The heat conductive base 60 is formed of metal such as, but not limited to aluminum or another metal alloy having a low heat capacity and low specific heat, and is dish like in configuration having a generally planar top inner surface 61, and an opposing planar bottom outer surface 62. A circumferentially extending lip 64 extends entirely about the circumference of the heat conductive base 60, extending generally upwardly therefrom and has an outer circumferential surface 66. The lip 64 further has an upper peripheral edge 65 that is spaced apart from, and vertically above the planar top inner surface 61.

(13) The upper peripheral edge 65 of the circumferentially extending lip 64 is interconnected with the bottom edge 25 of the flexible body 20 in a fluid tight engagement. In one preferred embodiment, the bottom edge 25 of the flexible body 20 is formed onto the upper peripheral edge 65 of the heat conductive base 60 during the manufacturing process so as to provide a fluid-tight seal therebetween, but other known attachment means are usable as well. The fluid tight interconnection of the heat conductive base 60 with the flexible body 20 provides for the cooking vessel 10 to be able to hold liquids and further defines the interior volume 28. The outer circumferential surface 66 and the planar bottom outer surface 62 define a bottom heat receiving portion of the cooking vessel 10.

(14) The heatsink 80 is interconnected to the bottom 62 and outer circumferential surface 66 of the heat conductive base 60 and comprises an annular shaped radiator 81 and a circumferentially extending shield 100.

(15) The annular shaped radiator 81 has a configuration of an annulus and has an upper edge portion 82, an opposing bottom edge portion 83, an inner circumferentially extending edge portion 84 defining an interior diameter 85, and an outer circumferentially extending edge portion 86 defining an exterior diameter 87. The radiator 81 is formed of heat conductive material, preferably a material having a low heat capacity and a low specific heat, such that when the annular shaped radiator 81 is exposed to a heat source, such as a camp stove 200 having a stove burner 201 emitting a flame 202 (FIGS. 6, 7) the radiator 81 efficiently absorbs the heat energy and passes the heat energy to and through the heat conductive base 60. In one preferred embodiment the annular shaped radiator 81 is formed of aluminum. In additional contemplated embodiments the annular shaped radiator 81 is formed of a metallic alloy.

(16) The radiator 81, in a first embodiment, has a plurality of regularly spaced bends 88 and defines a plurality of regularly spaced channels 89. The plurality of regularly spaced bends 88 and regularly spaced channels 89 increases the surface area that is exposed to the heat source, or flame 202 so as to absorb more heat therefrom and pass that heat energy to the heat conductive base 60. As shown in FIG. 5, the regularly spaced bends 88 are at both the upper edge portion 82 and opposing bottom edge portion 83 of the radiator 81, which increases the heat absorbing surface area that is communicated to the heat conductive base 60. The plurality of regularly spaced channels 89 are generally radially oriented relative to a center (not shown) of the radiator 81.

(17) The upper edge portion 82 annular shaped radiator 81 is in direct frictional contact with the planar bottom outer surface 62 of the heat conductive base 60. In one embodiment of the radiator 81 is structurally interconnected to the heat conductive base 60 and in a second embodiment, the radiator 81 is separate from, but maintained in direct frictional contact with the bottom planar surface 62 of the heat conductive base 60.

(18) The circumferentially extending shield 100, has an L-shaped cross-sectional configuration (FIG. 4) with a vertically extending sidewall 102 and an integral perpendicularly extending bottom 107. The vertically extending sidewall 102 has an upper edge portion 103, an opposing bottom edge portion 104, an outer circumferential surface 105 and an inner circumferential surface 106. The vertically extending sidewall 102 further defines a plurality of regularly spaced heat releasing orifices 111 that communicate between the outer circumferential surface 105 and the inner circumferential 106. The heat releasing orifices 111 further communicate with the plurality of regularly spaced channels 89 of the radiator 81, and as shown in FIG. 7, so as to direct the flame 202 generated by the stove 200 radially outwardly from the outer circumferentially extending surface 21 of the flexible body 20, thereby preventing the flame 202 from lapping upwardly around and about the flexible body 20. Preventing the flame 202 from contacting the flexible body 20 enhances the longevity and durability of the flexible body 20 and has been shown to prevent heat related deterioration of the flexible body 20. Further, the orifices 111 prevent the heat energy from being completely reflected downwardly onto the stove 200 which might cause risks of explosions or fire, or burns when a user attempts to adjust the stove 200.

(19) The perpendicularly extending bottom 107 has an inner upper surface 108 and an opposing outer bottom surface 109. The outer bottom surface 109 further has a radially inner edge portion 113 that defines a bottom orifice 110. Diameter 112 of the bottom orifice 110 is substantially similar in size to the interior diameter 85 of the annular shaped radiator 81. As shown in FIG. 5, the circumferentially extending shield 100 extends frictionally about and around the outer circumferentially extending edge portion 86 of the radiator and also extends radially inwardly immediately adjacent to the bottom edge portion 83 of the radiator 81. The upper edge portion 103 of the vertically extending sidewall 102 is structurally interconnected with the outer circumferential surface 66 of the heat conductive base 60 so that the heatsink 80 is securely interconnected to the heat conductive base 60 and is integral therewith.

(20) The perpendicularly extending bottom 107 provides structural integrity to the annular shaped radiator 81 and protects the plurality of bends 88 and channels 89 from being unintentionally bent, or otherwise deformed during use, such as when the cooking vessel 10 is placed on pot supports 203 of a camp stove 200, or perhaps in-delicately placed on an irregular surface, such as, but not limited to, the top of a stone/rock/stump. The bottom 107 further increases the heat receiving surface area.

(21) The bottom orifice 110 of the heatsink 80, in combination with a top to bottom thickness (not shown) of the annular shaped radiator 81, further provides a recess into which the stove burner 201 may be placed during use. Placement of the stove burner 201 into the recess reduces the amount of wind and undesirable airflow between the flame 202 and the heat conductive base 60 and has the tendency to prevent the stove 200 from going out unintentionally, which is a common occurrence when camp stoves 200 are used in unprotected windy conditions. Further still, placement of a stove burner 201 within the recess has the tendency to prevent the vessel 10 from unintentionally sliding off the stove 201 and pot supports 203.

(22) Testing has shown that the heatsink 80 of the instant invention materially improves performance of the cooking vessel 10 by increasing the efficiency of the cooking vessel 10. This material improvement in performance and efficiency is believed to be a result of increased surface area being exposed to the heat source from 202 and the transfer of that heat energy to, and through, the heat conductive base 60, and thereupon to the food items (not shown) within the interior volume 28. Testing has shown that 0.200 liters (200 grams) of water placed in the instant inventive collapsible cooking vessel with heatsink 10, and the same amount of water placed in four similarly sized/dimensioned cooking vessels (but without a heatsink) and placed on similar camp stoves 200 adjusted to produce similar amounts of heat, resulted in the water within the instant collapsible vessel with heatsink 10 boiling in 2.00 minutes, and the boiling water was evenly distributed across the upper surface 61 heat conductive base 60. The water in the four comparison vessels, on the other hand, took approximately 2.50 minutes to boil, and the boiling only occurred in the center region of the pot bottom.

(23) The removable lid 40, as shown in the Figures, has a top surface 41, a bottom surface 42 and defines a circumferential edge 43 with a diameter 44. In one preferred embodiment, the removable lid 40 defines a plurality of spacedly arrayed drain holes 45 therein. The plurality of drain holes 45 communicate between the top surface 41 and the bottom surface 42 and provide a means for a user to drain liquid from the interior volume 28 without risking loss of the desirable food products (not shown). The removable lid 40, further has a lid latch 46, a handle 49, lid latch protuberances 48 and lid thumb pads 47 which are useful when the vessel 10 is inverted such as to drain fluid through the plurality of drain holes 45 while retaining desirable food products within the interior volume 28. The diameter 44 of the removable lid 40 is such that the circumferential edge 43 of the removable lid 40 engages with the upper peripheral edge 43 of the flexible body 20, and the lid latch protuberances 48 releasably engage with the lid securing protuberances 31 carried by the annular ring 30.

Operation

(24) Having described the structure of our collapsible vessel with heatsink its operation may be understood.

(25) Assuming the collapsible cooking vessel with heatsink 10 is in its collapsed/transport configuration (FIG. 3) a user would detach the removable lid 40 by disengaging the latches 46, and would then exert an axial downward force directly on the generally planar top inner surface 61 of the heat conductive base 60, while holding onto the upper peripheral edge 21 of the flexible body 20. The axial downward pressure will cause the flexible body 20 and the nested portions thereof that have folded inwardly at and about the reduced thickness areas 27 to unfold and extend such that the flexible body 20 returns to an extended/use configuration. (FIG. 2). The instant collapsible vessel with heatsink 10 is thereafter used like any other cooking vessel. When use of the vessel 10 is complete, the above process is repeated in reverse to collapse the vessel 10 into its storage/transport configuration. (FIG. 3).
