Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to cooking oven liners. More particularly, the present invention relates to disposable cooking oven liners which enhance the cooking of food. 
     2. Description of the Prior Art 
     Numerous innovations for a disposable oven liner have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present invention as hereinafter contrasted. 
     In U.S. Pat. No. 5,423,309, titled, Oven Attachment for a Camping Lantern, invented by Rockford M. Miller, Sr and Timoth S. Mannen, an oven attachment is provided for a camping lantern, in which the oven attachment is configured to be attached to the lantern so as to form an integral component of the lantern. In particular, the oven attachment provides an enclosure in which foods and beverage containers can be placed and uniformly heated with the heat generated by a conventional camping lantern. The versatility of the oven attachment is enhanced by the ability to regulate the temperature of the enclosure with a damper assembly. Yet the oven attachment is constructed such that its use and structure does not interfere with the safe operation of the lantern as intended by the manufacturer, nor does the oven attachment significantly diminish the lighting capability of the lantern. 
     The patented invention differs from the present invention because the patented invention is an oven attachment specifically adapted to function in cooperation with a camping lantern. The heat from the lantern provides the cooking heat. The present invention is inserted into existing ovens functioning to improve the cooking characteristics and browning of food products. 
     In U.S. Pat. No. 4,667,075, titled Microwave Oven for Vehicles, invented by Takashi Sakurai, a microwave oven for a camping or other vehicle includes a heating room in which an object is heating by applying microwaves thereto, a microwave guide to propagate the microwaves into the heating room, a magnetron to produce the microwave for the microwave guide, and a voltage supply device to supply the magnetron with an appropriate voltage. The voltage supply device includes a transformer to boost the three-phase AC voltage from an alternator mounted on the vehicle, and a rectifying circuit to rectify the three-phase AC voltage boosted by the transformer. The magnetron receives the voltage rectified. The heater terminal and other main terminal of the magnetron are connected to terminals of the battery mounted on the vehicle. 
     The patented invention differs from the present invention because the patented invention is a microwave oven for a camping or other vehicle. The patented invention is not similar to present invention. 
     In U.S. Pat. No. 4,535,753, titled Radiant Heat Collector, invented by Leo Zayauskas, a radiant heat collector is disclosed in the form of a reflector oven. The oven collects heat from a heat source adjacent to the oven. The reflective surfaces are detachably secured to end plates, which plates are of a generally rectangular configuration. Tie rods may be used to retain the grill assembly, or tabs on either the grill or on the reflective surfaces, or on both, and may be used for this purpose with or without tie rods. The assembled reflector is of a generally elliptical section shape (rather than parabolic) to enhance the thorough heating of the material placed on the grill to be heated. The elliptical section encompasses one end of an ellipse about one focus line and a source of heat may be conveniently located at the other focus line. The major axis of the ellipse dips downward from the section to the heat source and the rack or grill is positioned under the section focus line essentially to one side of the major axis. The source of heat for the grill is generally an external source, such as a fire, positioned in front of and fairly close to the oven at the elliptical external focus line. The oven is readily assembled or disassembled to form a compact package and may be used indoors with a fireplace, for example, or outdoors when camping or picnicking. 
     The patented invention differs from the present invention because the patented invention is an oven which collects heat from a heat source adjacent to the oven such as an open fire. The patented invention has reflective focused surfaces for the purpose of reflecting heat toward the food product to be cooked. The patented invention is not designed to function on top of a stove burner. The present invention is a device which is placed inside an oven to improve the cooking properties and contain splatter from food products. The interior surface of the cube is heat reflective material. Venturi holes are critically placed to circulate air flow to improve the cooking characteristics and browning of food products. 
     The above patented inventions differ from the present invention because they fail to describe or claim at least one combination of the following features depicted in the present invention including an oven insert, having a cube like shape with a top opening cover, which is placed in an oven. The prior art inventions further, lack an interior surface of heat reflective material. Critically placed venturi holes function to circulate air flow and to improve the cooking characteristics of the oven. 
     Numerous innovations for disposable oven liner have been provided in the prior art that are adapted to be used. Even though these innovations may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the present invention as heretofore described. 
     SUMMARY OF THE INVENTION 
     The present invention is a disposable device which is placed inside an oven to improve the cooking properties and contain splatter from food products. The interior surface of the cube is heat reflective material. Venturi holes are critically placed to circulate air flow and to improve the cooking characteristics and browning of food products. 
     The types of problems encountered in the prior art are that cooking foods splatter the inside of an oven. Further, the location of the heating elements inside of an oven are cause uneven cooking. 
     In the prior art, unsuccessful attempts to solve this problem were attempted namely: devices using a remote heat source such as a campfire, lantern, and microwaves. Each attempted solution locates the device away from the heat source and does not adapt to an oven. Other attempts at a disposable splatter shielding were limited to the bottom portion of the oven. However, the problem was solved by the present invention because the present invention is inserted into an oven and encompasses the food products keeping splatters from reaching the oven walls. Further, the present invention enhances the cooking of food products by providing a more uniform distribution of heat throughout the food interior and surface. 
     The present invention solved a long felt need for a total interior splatter shield that collects splatters on the side, back, front, and top as well as the bottom. 
     Accordingly, it is an object of the present invention to provide a disposable splatter shield which protects the six interior sides of an oven. 
     More particularly, it is an object of the present invention to provide a disposable splatter shield which is stored in a compact folded condition, is deployed inside an oven and has apertures which enhance convection providing a more uniform heat distribution surrounding the food product. 
     In keeping with these objects, and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a disposable heat reflective material which is folded from a flat state by the user to fit the interior of an oven. 
     In accordance with another feature of the present invention, a front is secured to each side by tabs. 
     Another feature of the present invention is that a front aperture is baffled by a reflective flap which extends interiorly downward from the top of the front. 
     Yet another feature of the present invention is that a front aperture provides an inlet for heated air from the heating elements. 
     Still another feature of the present invention is that a top cover extend forward from the rear providing a top splatter shield and reflects heat downwardly. 
     Yet still another feature of the present invention is that vent apertures are provided between the top cover and the sides permitting air to exhaust. The escaping air draws replacement air through lower apertures thus circulating air carrying heat throughout the interior of the present invention. This promotes more even heat distribution, resulting in even cooking and browning. 
     Still yet another feature of the present invention is that the aperture openings are adjustable. 
     Another feature of the present invention is that the patented invention is made in various sizes. 
     Yet another feature of the present invention is that is manufactured from flat material 
     Still another feature of the present invention is that the present invention folds to a small size for transportation and storage. 
     Yet still another feature of the present invention is that when folded into a deployed shape, tabs located on the fold upwardly forming a drip pan. 
     Still yet another feature of the present invention is that juices from the food product splattered on the sides and top of the interior, of the present invention, collect, then drip onto the food product resulting in a self basting process occurring. 
     The novel features which are considered characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawings.
