FIG. 1 depicts one embodiment of a bottom view of a microwave mat 100. Although the illustrated microwave mat 100 of FIGS. 1-4 is shown and described with certain components and functionality, other embodiments of the microwave mat 100 may include fewer or more components to implement less or more functionality. The illustrated bottom view of the microwave mat 100 includes ridges 102 raised from a surface 104. In the illustrated embodiment, the microwave mat 100 is round. In some embodiments, the microwave mat 100 may vary in shape and size and may be a square, rectangle, oval, or any other shape suitable to rest below a container in a microwave oven and suitable for carrying the container by only contacting the microwave mat 100. Although not shown clearly in FIGS. 1 and 2, some embodiments include a lip portion near the edge of the microwave mat 100. The lip portion may be raised to allow for easier grip of the microwave mat 100. The raised lip allows a person to insert the person's fingers below the mat and grip the mat without contacting the bottom surface of the microwave oven or the surface of a turntable within the microwave oven. In some embodiments, the lip portion is slanted upwards. In some embodiment, the lip portion slants at an angle from a plane of a mat portion of the microwave mat. While the mat portion would lay flat on a flat surface, the lip portion would slant upwards from the flat surface. In some embodiments, the angle could be 15° or less. In some embodiments, the angle could be 90°. In the illustrated embodiment, the ridges 102 are circular. In some embodiments, the ridges 102 track the shape of the outer edge of the microwave mat 100. In some embodiments, the ridges 102 form a distinct shape from the outer edge of the microwave mat 100. In some embodiments, the ridges 102 are spaced evenly along the surface 104 of the microwave mat 100. In some embodiments, the ridges 102 are not spaced evenly along the surface 104. In some embodiments, the ridges 102 are spaced to optimally distribute heat efficiently and reduce the contact area of the microwave mat 100 against the surface of the turntable or microwave oven. In some embodiments, the microwave mat 100 is made from a single material. In some embodiments, the microwave mat 100 is made of a heat resistant material. The microwave mat 100 may be made from silicone or other material resistant to heating in a microwave oven. In this way, the microwave mat 100 may serve to insulate the hands of a person when they remove the contents of a microwave oven. A container of food or other item may be placed on top of the microwave mat 100 and heated by the microwave oven. A person may then grip the microwave mat 100 without contacting the food container or any surface of the microwave oven. In some embodiments, the material of the microwave mat 100 is flexible. The flexibility allows the microwave mat 100 to be used with many different containers of all different shapes and sizes. As the microwave mat 100 is flexible it will serve to track the container when lifted and removed from the microwave oven, whether it is a plate, bowl, cup, mug, or other dish. The ridges 102 also allow for superior grip of the microwave mat 100. The microwave mat 100 may also be made of a material with a high coefficient of friction to reduce the possibility of the heated container slipping out of the microwave mat 100 upon transport. The thickness, depth, and cross sectional shape of the ridges may vary. Although not depicted, the microwave mat 100 may include other components to facilitate the advantages and functions outlined above. In some embodiments, the material will resist heat to at least 450 degrees Fahrenheit. In some embodiments, the material will resist heat to at least 400 degrees Fahrenheit or a range of temperatures. In some embodiments, the material may heat during prolonged exposure to microwave heating or if heated alone but resists heat when placed with another item in the microwave oven. The ridges 102 help dissipate heat faster to allow for a mat that may be gripped comfortably from the microwave oven when removing hot items.
FIG. 2 depicts one embodiment of a top view of the microwave mat 100 of FIG. 1. The illustrated microwave mat 100 includes a flat top surface 106. The flat top surface 106 is the surface that an item or container would rest upon in the microwave. In some embodiments the top surface 106 may include ridges similar to the ridges 102 described in conjunction with FIG. 1. In such an embodiment, the raised ridges on the top surface 106 would contact the item or food container during heating of the item or transport of the item. In some embodiments, the raised ridges on the top surface 106 allow for easier grip of the microwave mat 100 or may assist in heat dissipation and may reduce the contact area between the microwave mat 100 and the food container.
FIG. 3 depicts one embodiment of a cross-sectional side view of a microwave mat 100 similar to FIGS. 1 and 2. The cross-sectional side view shows the cross section at a center line along a circular microwave mat similar to the microwave mat 100 shown in FIGS. 1 and 2. The cross sectional view shows the cross section of the ridges 102 and how the ridges 102 are raised form the surface 104. In the illustrated embodiment, the ridges 102 are rectangular in cross-sectional shape with substantial uniformity in depth and width. The ridges 102 may include various cross-sectional shapes including rounded. The ridges 102 may also be narrower at the base of the cross section or may be wider at the base of the cross section. In some embodiments, the cross section of the ridges 102 may not be uniform along the path the ridges 102 follow along the surface 104. The ridges 102 may include different shapes when viewed from the bottom of the microwave mat 100 and may or may not track or follow the edges of the microwave mat 100. For example, the microwave mat 100 may be a rectangular while the ridges 102 form a circular shape. Or the microwave mat 100 may be an oval and the ridges 102 may be straight lines. The illustrated embodiment includes a lip portion 108 and a mat portion 110. The mat portion 110 tracks or conforms to the surface on which it is set. For example, the mat portion 110 lays flat when the microwave mat 100 is placed on a flat surface. The lip portion 108 is raised from the flat surface when the microwave mat 100 is placed on a flat surface. This allows a person to insert their fingers under the microwave mat 100 without the need to touch the surface on which the microwave mat 100 rests. The surface may be hot. In addition the raised lip portion 108 may reduce the heat buildup in the microwave mat 100 during operation of the microwave oven.
FIG. 4 depicts one embodiment of a cross-sectional side view of a center slice of the microwave mat 100 of FIG. 3. FIG. 4 shows many of the same features as FIG. 3.
