The present invention belongs to the field of devices for preparation, formation and cooking of articles of food, and more particularly relates to a novel device for cooking grilled, dome shaped hamburger patties.
While preparing grilled hamburger meat patties, it is important that the meat is cooked uniformly, not undercooked or overburnt and also remains juicy within. The problem usually faced while cooking them is that the patties are cooked well on the outside but not cooked uniformly in the inside, especially the central portion of the patty. Another effect of the uneven cooking is that the hamburger patties shrink in the inner central portion. When the melted fat or grease from within the hamburger patty runs outside onto the charcoal, it causes a high flame that often results in blackening of the exterior surface of the hamburger patty. Also the grease accumulated on the external surface of hamburger patty makes it rather unappetizing and unhealthy to eat. There is also the issue of “charcoaling” of the hamburger patty which is caused by grilling with high flames.
Below are given some of the known prior art.
U.S. Pat. No. 5,596,922 entitled “Apparatus for cooking a food product” describes an apparatus for cooking a food product, for example a hamburger, comprising a mould assembly for cooking the hamburger. The mould assembly is formed from first and second moulds formed on upper and lower bodies. When the moulds are moved apart spaces between the side wall portions allow the hamburger to be easily removed. The apparatus aims for easy removal of the hamburger from the mould.
Patent CA2272151 entitled “PATISAFE” elaborates that hamburger patties that are prepared through mass-production must be well cooked but not burned and should also remain juicy. To ensure that the hamburger meat is well cooked, the amount of heat should be adjusted to the thickness of the patties. Another way to cook the patties properly is to adjust the thickness of the patties to the amount of heat available. The disclosed invention is based on matching the thickness of the meat patties to the amount of heat available from cooking facilities.
U.S. Pat. No. 8,701,552 entitled “Forming device for articles of food” describes methods and devices configured for forming exterior portions and interior portions of a food article so as to form a cavity for placement of similar or different articles of food therein.
U.S. Pat. No. 7,640,929 entitled “Barbecue grill cooking chamber with grease control structures” discloses a barbecue grill assembly comprising a cooking chamber with a cover and a firebox.
U.S. Pat. No. 5,112,634 entitled “Method and apparatus for making ground meat patties” discloses a household hamburger maker having a hollow, circular outer collar and a hand-held center plug. Ground meat is placed into the hollow area of the outer collar, and the center plug is inserted into the same hollow area and pressed down against the ground meat. While the center plug is being pressed down, it is also twisted alternately clockwise and counterclockwise, which produces a smooth top surface on the ground meat as it is shaped into a hamburger patty. While still being twisted, the center plug is pulled back up and away from the hamburger patty, leaving behind a correctly-shaped patty that has a smooth top surface.
Despite various improvements and progress in the field, some of the major obstacles that still exist are presented herein below. The existing devices are unable to overcome the limitations of providing a dome shaped hamburger patty cooked on a grill, which is uniformly cooked, does not exhibit “charcoaling” of the exterior surface, does not have fat or grease run off and accumulate outside the patty and is also juicy on the inside. Besides the existing apparatus are not simple to use or manufacture. Accordingly, improvements are needed in the existing devices that negate the above shortcomings.
It is observed that the purpose and methodology of all the above inventions that are part of prior art do not envisage the unique embodiment of an apparatus for preparation of dome shaped hamburger patty cooked by grilling, as described in the present application.
The scope of the invention is to be determined by the terminology of the following description, claims, drawings and the legal equivalents thereof.
The present invention may be summarized, at least in part, with reference to its objects.
It is therefore a primary objective of the present invention to provide a a novel device for cooking grilled, dome shaped hamburger patties.
Another objective of the present invention is to provide a device capable of preparing grilled, dome shaped hamburger patties that are uniformly cooked, do not have grease or fat accumulated on the outside and are juicy within.
Another objective of the present invention is to provide a device such that the hamburger patties do not have a burnt, “charcoaled” appearance caused by high flames. Yet another objective is to provide a device that can be used to prepare hamburger patties that exhibit minimum shrinkage.
The invention described herein thus comprises a novel device for preparation of dome-shaped, grilled hamburger patty. The device comprising:
The above summary is intended to illustrate exemplary embodiments of the invention, which will be best understood in conjunction with the detailed description to follow, and are not intended to limit the scope of the invention. Additional objects and embodiments of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention. Thus these and other objects of the present invention will be more readily apparent when considered in reference to the following description and when taken in conjunction with the accompanying drawings.
As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of an invention that may be embodied in various and alternative forms. Therefore, specific functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for the claims and/or as a representative basis for teaching one skilled in the art to variously employ the present invention.
The following description is presented to enable any person skilled in the art to make and use the invention, and is provided in the context of particular applications of the invention and their requirements.
The invention described herein thus comprises a novel, device for making dome shaped, grilled hamburger patties. Said device is capable of preparing hamburger patties that are uniformly cooked, exhibit good appearance and do not have excess fat on the surface. The device comprises:
a bottom dome member configured substantially in the shape of a hemispherical dome with a flat plate running around a circumferential peripheral edge, said bottom dome member characterized by a plurality of openings,
a top dome member configured substantially in the shape of a hemispherical dome, said top dome member characterized with a central opening on a vertex region of the top dome member,
a top flat plate member non-removably affixed vertically above the top dome member, said top flat plate characterized by a plurality of radially arranged openings and a central opening,
wherein said bottom dome member and said top dome member are conjoined with a pair of height adjustable locking members and a corresponding rod, and an opening locking member and a corresponding rod, said pair of the height adjustable locking members and the opening locking member non-removably attached to and provided on diametrically opposite locations on the flat plate running around the circumferential peripheral edge of the bottom dome member,
and,
said bottom dome member and said top dome member adapted to receive a hamburger patty between them.
The bottom dome member and top dome member are shaped such that the hamburger patty conforms substantially to the curvature of the bottom and top dome members and is molded accordingly.
An opening locking member 15 and its corresponding rod 16 are non-removably attached to one point on the flat plate portion of the bottom dome member 14. Pair of height adjustable locking members 17 and a corresponding rod 18 are non-removably attached on the flat plate portion of the bottom dome member 14, at a diametrically opposing region to where opening locking member 15 and its corresponding rod 16 are provided. 17 and 18 function as a hinged mechanism, when 16 is raised upwards to open the top dome member 13 for placing the hamburger patty. The top dome member 13 is positioned vertically above the bottom dome member 14 and conjoined by opening locking member 15 at one point and height adjustable locking members 17 on the diametrically opposite side. The position of the locking members can be adjusted according to the desired thickness of the hamburger patty. Excessive heat causes the metal body of the device to expand and makes it difficult to use any other mechanism for opening and adjusting the height of the device members and also be simple enough for a user (cook) to use.
The present mechanism of height adjustable locking members 17, the corresponding rod 18, opening locking member 15 and the corresponding rod 16 is the most preferred embodiment to adjust to adjust to the spacing between the top dome member 13 and bottom dome member 14 as per desired thickness of hamburger patty such that the user (cook) can release and lock with ease.
The top dome member 13 is provided with a central opening or slot 20 on its top vertex region. This is to drain out excess fat or grease generated from the patty while grilling. Also the slot 20 helps in controlling the metal expansion i.e. warping because of excessive heat on the top dome member 13 and thereby keeps it in shape. The slot 20 thus controls the heat transfer and prevents warping of the top dome member 13.
In alternate embodiments, the slot 20 may be provided in the form of a plurality of symmetric geometric openings.
The top flat plate member 11 is non removably connected, by means such as welding, to the top dome member 13 and is provided for support and stability to the whole device. A user can flip the device upside down for uniform cooking and the device remains stable. The plurality of radially arranged openings of the top flat plate member 11 lead to uniform heat distribution.
In a preferred embodiment of the invention, the opening on the vertex region of the top dome member is provided in the shape of an X. In a preferred embodiment, the material of all the components is stainless steel.
Experiments were carried out to test the efficiency of the present invention and are tabulated as below. The following experimental trials were carried out using a device according to the present invention with the following specifications. As seen from the results, the overall shrinkage in diameter of the hamburger patty is in the range of 5% to 23%.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
