This invention relates to making poultry, meat, and fish in a commercial (restaurant or cafe) or home environment. Using the press lock cooker of the present invention, anyone can make fresh, delicious poultry, meat, and fish with just the right tools. Although primarily aimed at commercial use, the press lock cooker for making poultry, meat, and fish of the present invention can also be successfully used at home for making fresh fried poultry, meat, and fish to order.
Poultry, meat, and fish are popular restaurant and home-cooked dishes with adults and children alike. Currently, there is a number of ways to make fried poultry, meat, and fish as fully disclosed in the brief description of the prior art, but none are so easy and simple to use as the inexpensive press lock cooker of the present invention.
In addition to being inexpensive, the press lock cooker can vary regulate the thickness of the poultry, meat, and fish that are being cooked by simply varying the height of the adjustable press. Furthermore, the user can regulate how fast the food cooks by adjusting the pressure applied to the food. Poultry, for example chicken, may be cooked crispy with the press lock cooker. Thus, the consumers—both chefs at restaurants and moms making dinner at home—have the control over the thickness of the final dish and how fast it cooks.
The current state of the art involves frying poultry, including chicken, meat, including steaks, burgers and chops, and fish using either two-sided grills with a pair of pivotally-connected cooking plates or griddles, using a heavy, weighted press with a plate that presses the food down while it is being cooked, or using a handheld press, applying pressure to the food manually exerting force through the handle. This is done to ensure the better contact of the food with the frying pan, and to prevent the sides from curling from the heat. The improved contact between the food and the pan ensures better heat distribution through the food and helps the user regulate how fast, and how thoroughly, the food cooks.
However, neither of these methods provides a great degree of adjustability because the weight of the food press remains constant (usually as a heavy or weighted plate), and the two-sided grills have a preset thickness of the food contemplated to be produced. Furthermore, the heavy presses weigh many pounds, and are simply not as practical to produce (require more materials), store or transport because they are heavy. The manual presses have the disadvantage in that they require constant or frequent application of pressure to achieve the desired effect.
What is needed is an easy-to-use, lightweight cooker for making poultry, meat, and fish of any shape and size the users want. A great variation of foods of varying shapes, sizes, and thickness can be cooked using the press lock cooker of the present invention.
This invention meets the current need for such a cooker. A novel press lock cooker for making poultry, meat, and fish is provided. The preferred embodiment of the press lock cooker of the present invention is a frying pan with a plurality of substantially vertical channels in the walls of the frying pan, each channel having a plurality of slots or horizontal channels extending substantially horizontally in the walls of the frying pan from each channel, and a substantially flat-bottomed cover with a handle and a plurality of cooperating protrusions reciprocal in number to the number of channels, where the protrusions of the cover are capable of interlocking with the slots in walls of the frying pan to lock in and cook poultry, meat, and fish of different shapes and sizes in the restaurant or home environment. Food such as poultry (chicken for example) may also be cooked to be crispy under pressure using the press lock cooker.
Yet another embodiment of the press lock cooker of the present invention is a frying pan with a plurality of short protrusions extending inward towards the center of the frying pan from at or below the upper edge of the frying pan, and a substantially flat-bottomed cover with a handle and a reciprocal plurality of cooperating protrusions capable of interlocking with the protrusions on the frying pan to cook poultry, meat, and fish of different shapes and sizes in the restaurant or home environment.
The cover of the press lock cooker may be comprised of two parts: an upper part with a handle and a reciprocal plurality of cooperating protrusions capable of interlocking with the protrusions of the press lock cooker, and a substantially flat-bottomed lower part connected to the upper part by an adjustable screw or different means that allow the user to regulate the height of the lower part over the meat (and the distance between the bottom of the frying pan and the substantially flat-bottomed lower part).
The upper part of the cover is preferably removably attachable to the lower part of the cover for the ease of removing the bottom part and easy cleaning. The preferred method of attachment of the upper part to the lower part is by using a screw permanently mounted on the upper side of the lower part, preferably terminating in a handle, for example a knob, above the upper part. However, other methods of attachment may be used, such as latches and other means known in the art.
These features, aspects and advantages of the novel press lock cooker and a kit for making poultry, meat, and fish will become further understood with reference to the following description and accompanying drawings where
As illustrated in
Each channel 30 has at least one, but preferably at least two substantially horizontal channels 35 extending substantially horizontally in the wall 12 of the frying pan 10 from each channel 30. Having more slots allows for greater adjustability of the height of the cover 20 over the bottom 16. The wall 12 of the frying pan 10 is preferably at least two inches high and includes several substantially horizontal channels 35 extending from channels 30 in the wall 12. The channel 30 and the lowest substantially horizontal channel 35 may terminate an inch or half-an-inch above the bottom 16 of the frying pan 10, which has to be determined during the design and manufacture of the specific embodiment of the press lock cooker. The wall 12 of the frying pan 10 should be of sufficient thickness to allow for the channels 30 and substantially horizontal channels 35. The channels 30 and substantially horizontal channels 35 preferably have the same depth in the wall 12 of the frying pan 10.
The cover 20 is a substantially flat-bottomed cover with a handle 22 and a plurality of cooperating protrusions 40 reciprocal in number to the number of channels 30. In the embodiment illustrated in
Both the frying pan 10 and the cover 20 may be manufactured from the commercially used materials: cast iron, stainless steel, ceramic and other suitable materials and combinations thereof known in the art. For example the cover 20 may be made from glass, with a steel rim including the protrusions 40 pursuant to the disclosure of the present invention.
The cover 20 is sized to be slightly less in diameter than the diameter of the frying pan 10 when measured from the inner surface of the wall 12. The protrusions 40 are sized to be of such length that the combined diameter of the frying pan 10, when measured from the inner surface of the wall 12, and the length of two approximately opposite protrusions 40 are greater than the diameter of the frying pan 10 when measured from the inner surface of the wall 12, but slightly less than the combined diameter of the frying pan 10 measured from the inner surface of the wall 12 and the depth of the reciprocating channels 30.
The protrusions 40 are positioned on the cover 20 in a reciprocal fashion to the channels 30, and preferably spaced equidistantly from one another, just as the channels 30 should be. The protrusions 40 are sized so that they are able to pass through the channels 30 when the cover 20 is inserted into the frying pan 10, but the protrusions 40 are engaged by the substantially horizontal channels 35 when the cover 20 is twisted or rotated in the direction of the substantially horizontal channels 35. It should be noted that the figures illustrate an embodiment that utilizes a right-hand twist or rotating motion to lock the cover 20 in place because the substantially horizontal channels 35 are on the right side of each channel 30 from which the substantially horizontal channels 35 extend, but the substantially horizontal channels 35 may also be on the left side of each channel 30 and then the twist or rotating motion of the cover 20 to lock it will be left-handed.
When in use, the user positions the food to be cooked on the bottom 16 of the frying pan 10, takes the cover 20 by the handle 22, aligns the protrusions 40 on the cover 20 with the channels 30 in the wall 12 of the frying pan 10, and inserts the cover 20 into the frying pan 10, keeping the cover 20 substantially parallel to the bottom 16 so that the cooperating protrusions 40 pass unimpeded through the channels 30 until the cover 20 comes in contact with the food on the bottom 16 of the frying pan 10. When the cover 20 is on top of the food that is to be cooked, the user presses the cover 20 to press the food to the thickness that is desired, and, while applying constant pressure to the cover 20, aligns the protrusions 40 with the substantially horizontal channels 35 that will yield the desired height of the cover 20 over the bottom 16, which equates to the desired thickness of the food to be pressed, and twists or rotates the cover 20 clockwise so that the protrusions 40 are substantially within the substantially horizontal channels 35. The user then releases the handle 22 of the cover 20, which should remain securely in place propped up and held by the springing action of the pressed food but also held in place by the substantially horizontal channels 35 that engaged the protrusions 40.
The food is then cooked at the intensity desired, and the thickness of the food, i.e., poultry, meat, and fish, may be more or less depending on the level of compression by the cover 20 selected by the user, and it determines how well and how fast the food cooks.
Although the press lock cooker of the present invention will work with only two substantially vertical channels 30 in the wall 12 of the frying pan 10, which channels 30 should be substantially diametrically opposite in such configuration, it is preferable to have three or more substantially vertical channels 30 in the wall 12 of the frying pan 10 for secure, non-wobbling retention of the cover 20. When there are three or more substantially vertical channels 30 in the wall 12 of the frying pan 10, the substantially vertical channels 30 are preferably equidistantly positioned from one another in the wall 12 of the frying pan 10. There may be many variations of the present invention, employing three to eight vertical channels 30 in the wall 12 of the frying pan 10.
An enlarged view of one substantially vertical channel 30 and its corresponding substantially horizontal channels 35 are illustrated in
The protrusions 40 are substantially planar, being substantially in the same plane as the cover 20. The protrusions 40 are thus also substantially parallel to the bottom 16 of the frying pan 10. The protrusions 40 look like outward gear teeth, and they may be substantially square as illustrated in
Although the preferred embodiment of the present invention utilizes and round frying pan 10 and a round cover 20, the frying pan 10 and, correspondingly, the cover 20 may be square or rectangular. The difference in use would be in the locking motion of the cover 20: the user would not be twisting or rotating the cover 20, but rather sliding the cover 20 so that the protrusions 40 are engaged by the substantially horizontal channels 35 of the walls.
If necessary, the user can unlock the cover 20 and press it further down and lock the cover 20 at horizontal channels 35 that are lower than the horizontal channels 35 in which the cover 20 was previously locked. This may be desirable when the food loses some of its mass or moisture and becomes thinner as the result of cooking.
Another embodiment of the novel press lock cooker of the present invention is illustrated in
In this alternative embodiment, the cover 20 has a number of outward protrusions 60 reciprocal to the number of the inward protrusions 50. As illustrated in
To use the press lock cooker, the user places the food to be cooked on the bottom 16 of the frying pan 10. Unless the height of the cover 20 is adjustable, the top part of the food should typically be above the inward protrusions 50 in the frying pan 10. While holding the cover 20 by the handle 22, the user then inserts the cover 20 into the frying pan 10, and presses the food into the frying pan 10, thus compressing the food while allowing the cover 20 and the outward protrusions 40 of the cover 20 to pass between the inward protrusions 30 of the frying pan. When the outward protrusions 60 of the cover 20 are below the inward protrusions 50 of the frying pan 10, the user twists the cover 20 and positions the outward protrusions 60 of the cover 20 below the inward protrusions 50, thus locking the cover 20 in place. The combination of the food's resistance to the cover 20 and the friction between the outward protrusions 60 and the inward protrusions 50 will keep the cover 20 securely in place when the food is being cooked.
Although this embodiment of the press lock cooker will work with only two inward protrusions 50, which protrusions 50 should be substantially diametrically opposite in such configuration, it is preferable to have three or more protrusions 50 for secure, non-wobbling retention of the cover 20. When there are three or more inward protrusions 50, the inward protrusions 50 are preferably equidistantly positioned from one another along the wall 12 of the frying pan 10. There may be many variations of the present invention, employing three to eight inward protrusions 50.
As illustrated in
This embodiment of the cover 20 has a further advantage of enabling the user to adjust the height of the bottom part 28 after the cooking process has started if it is necessary to adjust the height because the adjustment may be made from the cover 20 closed position by simply rotating the handle or knob 23 to adjust the screw 21, thereby lowering or raising the bottom part 28 of the cover 20 and thus exerting more or less pressure on the food that is being cooked.
As further illustrated in
Instead of the groove or channel 62 and ridge 52 locking, other retaining configurations may be used: semi-spherical protrusion and cooperating semi-spherical depression in the cooperating inward protrusions 50 and outward protrusions 60, or any other number of cooperating protrusions and receptacles to further aid in retaining the cover 20 in the pan 10 and prevent it from slipping.
