No. 7,282,532, which claims the benefit of and priority to U.S. Provisional Application 60/476,325, filed Jun. 6, 2003. Both of the applications are hereby incorporated by reference.
A need therefore exists for an apparatus that could be used in conjunction with a flexible baking container that would permit easy transport of the baking container. A need further exists for an apparatus that could be incorporated into the flexible baking container so that together the device and bakeware are a self-contained unit. Still another need exists for an apparatus that can be readily removed from the baking container periodically for cleaning.
A need therefore exists for flexible bakeware that has improved food release qualities as compared to currently used flexible bakeware. A need further exists for a compound that can be easily and inexpensively manufactured into flexible bakeware. The compound should be non-toxic and should not impart an odor or taste to food products prepared in the bakeware.
BRIEF SUMMARY OF THE INVENTION The problems presented by existing flexible bakeware are solved by the present invention. A flexible bakeware compound is provided that includes a methyl vinyl silicone polymer from about 40 to 70 weight percent, a filler from about 5 to 50 weight percent, a curing agent from about 0.1 to 5 weight percent, and polytetrafluoroethylene from about 0.1 to 15 weight percent. In a preferred embodiment, the polytetrafluoroethylene is present in an amount of about 6 percent. The filler is preferably ground quartz, and the curing agent is preferably chloro platanic acid.
Also provided by the present invention is a flexible bakeware compound having a methyl vinyl silicone polymer of about 61 weight percent, a filler of about 28.5 weight percent, a curing agent of about 0.57 weight percent, and polytetrafluoroethylene of about 6 weight percent. Preferably, the filler is ground quartz, and the curing agent is chloro platanic acid. The flexible bakeware compound may also include high vinyl silicone gum from about 1.1 weight percent, a pigment from about 1.1 weight percent, zinc stearate from about 0.14 weight percent, silicone hydride from about 1.7 weight percent, and ethynl cyclohexanol from about 0.01 weight percent.
A method for baking a food product is also provided by the present invention. The method includes the step of providing a flexible baking container formed from an addition-cured silicone polymer having polytetrafluoroethylene from about 0.1 to 15 weight percent. A food product is deposited in the baking container, and the container is placed in an oven at a baking temperature for a predetermined time until the food product is baked. The food product is then removed from the baking container.
The invention further provides an elastomeric baking container having a basin and shoulder surrounding the basin. A receiving channel is disposed in the shoulder of the baking container and receives a carrier. The placement of the carrier within the receiving channel provides additional rigidity to the shoulder, which makes the baking container easier to carry.
A method of baking a food product is provided by the present invention and includes the steps of providing a flexible baking container having a basin and a shoulder. A receiving channel is disposed in the shoulder, and a carrier is received by the receiving channel. A food product is deposited in the baking container, and the flexible baking container is carried to an oven by gripping the carrier, or some portion of the carrier along with the shoulder of the baking container. The baking container is placed in an oven at a baking temperature for a predetermined amount of time until the food product is baked.
The carrier of the present invention can be provided in many different shapes and sizes. The shape of the carrier will generally match the shape of the receiving channel. For example, the carrier can be made from a rod with a circular cross section. The receiving channel in this case would have a circular cross section. In some instances, a portion of the carrier may extend out of the shoulder of the bakeware as a handle. The presence of handles is not required but may make the bakeware easier to carry.
Another carrier that may be used is one for a plurality of muffin cups (i.e. bakeware, or baking containers). This carrier is preferably a flat, rigid plate with a plurality of apertures. A flexible muffin cup is placed within each aperture so that a receiving channel on a shoulder of the muffin cup receives a portion of the flat carrier. The receiving channel may even have a depression for receiving a lip formed on an edge of the carrier's aperture. When the depression engages the lip of the carrier, the muffin cup is more securely attached to the carrier and less likely to become inadvertently disengaged from the carrier.

A shoulder 277 is formed at an end of the wall 273 opposite floor 275, the shoulder 277 extending completely around the perimeter of the baking container 271. Shoulder 277 includes an outer surface 281, an inner surface 282, an upper surface 283, and a lower surface 285. A receiving channel 291 having a rectangular cross section is disposed in the shoulder 277 with an entry slot 295 positioned between the lower surface 285 of the shoulder 277 and the receiving channel 291. In the preferred embodiment, the entry slot 295 is disposed adjacent the lower surface 285 (as shown in FIG. 26), but it is conceivable that the entry slot 295 could be disposed adjacent the outer surface 281, the inner surface 282, or the upper surface 283.
Referring more specifically to FIG. 23, a carrier 301 according to an alternative embodiment of the present invention is used in conjunction with flexible baking container 271. Carrier 301 is a ring-shaped plate having a central aperture 303 and is made of metal or temperature-resistant plastic. The shape and size of carrier 301 closely approximate those of the receiving channel 291 of baking container 271.
The flexible bakeware (i.e. the muffin cups 41, 51, the rectangular baking containers 111, 171, and the round baking containers 211, 271) composition of the present invention is preferably made from an addition-cured silicone material. The following table illustrates the preferred amounts and potential ranges for the flexible bakeware composition of the present invention:
Ground Quartz (filler)
Black Iron Oxide (pigment)
Zinc Stearate (internal mold
Chloro Platanic Acid (cross-
linking agent)
0.05-5 The flexible bakeware compound preferably contains 0.1 to 15 weight percent of polytetrafluoroethylene (PTFE). Testing of silicone bakeware with these amounts of PTFE has revealed superior release properties compared to silicone bakeware without PTFE. Several different compounds were tested by baking foods in the bakeware and then determining the amount of food residue remaining in the bakeware following the removal of the baked goods. Clearly, less food residue in the bakeware indicates better release properties. Silicone bakeware without PTFE required the use of a non-stick spray or flour to eliminate food residue following baking. Although silicone bakeware having PTFE ranging from 0.1 to 15 weight percent exhibited improved release properties without the use of a non-stick spray or flour, the optimum composition was determined to include six (6) weight percent PTFE.
High vinyl silicone gum is preferably added to the compound in an amount of about 1.1 weight percent; however, the compound could include high vinyl silicone gum in any amount between about 0.5 and 10 weight percent. The vinyl component of high vinyl silicone gum includes pendant vinyl in an amount of 8-20 weight percent of the high vinyl silicone gum, with a preferred amount of 14 weight percent.
Referring to FIG. 27, a method for baking a food product 309 according to the present invention includes, in step 311, providing a flexible baking container formed from an addition-cured silicone polymer having polytetrafluoroethylene in amount of about 0.1 to 15 weight percent. In step 313 a carrier adapted to be received by a receiving channel in the flexible baking container is provided. A user deposits a food product in the baking container at step 315, and the baking container is placed in an oven at a baking temperature for a predetermined time until the food product is baked at step 317. The baked food product is removed from the baking container at step 319.
The primary advantage provided by the carrier is that it allows a user of flexible bakeware to more easily lift and transport the bakeware while baking. By providing rigidity around the perimeter of the flexible bakeware, it is no longer necessary to support the flexible from underneath such as with a cooking sheet or tray. Another advantage is provided by the handle portions of the carrier. The handle portions extend outward from the perimeter of the flexible bakeware and provide a larger gripping surface for a user carrying the bakeware. Still another advantage of the carrier system is that it is easily and inexpensively manufactured. Flexible bakeware can be easily manufactured with a receiving channel in a shoulder that surrounds the perimeter of the bakeware. The carrier can then be made to fit within the receiving channel to provide the needed rigidity to a portion of the bakeware.
