(8) As used in the description herein and throughout the claims that follow, the meaning of a, an, and the includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of in includes in and on unless the context clearly dictates otherwise.

(9) Unless the context dictates the contrary, all ranges set forth herein should be interpreted as being inclusive of their endpoints, and open-ended ranges should be interpreted to include only commercially practical values. Similarly, all lists of values should be considered as inclusive of intermediate values unless the context indicates the contrary.

(10) The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value with a range is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g. such as) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.

(11) Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.

(12) The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

(13) As used herein, and unless the context dictates otherwise, the term coupled to is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms coupled to and coupled with are used synonymously.

(14) As used herein interchangeably, the term bun or roll means a piece of bread that is made by cooking a portion of bread dough.

(15) As shown in FIG. 1, a preferred set of contemplated methods 100 for making a pocketed bread bun includes at least four main steps: Step 110inserting one end of a tube into a portion of bread dough; Step 120supplying air into the portion through the tube to produce an air pocket; Step 130cooking the portion to produce an at least partially cooked bun; Step 140cutting the bun into at least a first piece having a first cavity and a second piece having a second cavity.

(16) Optional step 135 includes removing the tube from the bread dough before step 140. Other optional steps include optional step 101placing the bread dough into an expandable mold; optional step 102using an arm to control expansion of the mold; optional step 103using a processor to operate at least an arm; optional step 104supplying air to a balloon or other expandable device; and optional step 105using a compressor to compress ambient atmospheric air. These optional steps (101-104) can be performed before, during, or after steps 110-130.

(17) In step 110, one end of a tube is placed inside an amount of bread dough. The tube can be inserted into a portion of dough in any suitable manner, by hand or by machine. The dough can be made of any material that is suitable for producing a bun. Contemplated ingredients include flour, water, oil, and optionally one or more other ingredients typically included in bread making, including for example, egg, salt, sugar, butter, milk, buttermilk, cream, honey, yeast, and baking soda. Contemplated flours include wheat, corn, rye, bean, chickpea, buckwheat, cornmeal, potato, potato starch, rice, and any combinations of these. Contemplated flours can also be gluten-free. In preferred embodiments, the portion of bread dough comprises at least 2% oil (by weight) to increase its elasticity to help prevent rupture of dough and air leakage.

(18) In step 120, air is supplied into the portion of bread dough through the tube to produce an air pocket. Preferably, the temperature of the air and the bread dough is at least 30 C., to increase the elasticity of the bread dough. In optional step 105, an air compressor is used to compress ambient atmospheric air for use in the step 120. Alternatively, compressed air can be supplied from a gas cylinder with compressed air (nitrogen, carbon dioxide, or atmospheric air) ready for use. It is contemplated that compressed air is used in a range of pressures from high-pressures up to 750 psi and also at lower pressures of 15 psi. Ideally, air is purified (e.g., filtered) to rid of dust, bacteria, and other debris and pollutants before the air is used to form an air pocket inside the bread dough.

(19) In optional step 101, the bread dough is placed into an expandable mold, preferably prior to the step 120 of supplying air into the portion. In optional step 102, one or more (preferably two, four, or six) arms are used to control the expansion of the mold. Contemplated arms include mechanical rod capable of extending and contracting or springs. In optional step 103, a processor, for example, a computer, is used to operate the arm to control the expansion of the mold.

(20) In optional step 104, air is supplied into a balloon (or other expandable object) that has been placed inside a portion of bread dough. The air inside the balloon or expandable object is still considered an air pocket. In preferred embodiments, the air pocket is substantially spherical. In other embodiments, the air pocket has an eccentricity of at least 2:1. Preferably, the air pocket has a volume of at least 100 cm.sup.2. Alternatively or additionally, the air pocket has a volume at least 40% of a volume of the bun, including the air pocket.

(21) In step 130, the portion of dough is cooked to produce an at least partially cooked bun. The bread dough can be cooked by baking, steaming, frying, or any other suitable cooking methods to produce a bun. In preferred embodiments, the dough is baked in an oven at temperatures of less than 250 C., for 15-20 min. Excessively high temperatures and prolong time are avoided to prevent excessive crusting and bubbling. In preferred embodiments, cooking is performed while having the tube inside the portion of dough. When cooked, buns can assume any shape or form of the mold. Preferred buns have a substantially spherical shape, with a diameter of at least 5 cm, such that the final product would have a cavity large enough to hold fillings of a typical hamburger or sandwich. Contemplated preferred final products have a diameter of at least 5 cm and as long as 20 cm.

(22) In optional step 135, the tube is removed from bun before the step of 140. In step 140, the bun is cut into at least two pieces. In preferred embodiments, the bun is cut significantly off center, such that the cavity in one portion of the bun has a volume at least 50% larger than the volume of the cavity in the mating portion of the bun. More preferably, the cavity in one portion of the bun has a volume at least twice as large as the volume of the cavity in the mating portion of the bun.

(23) As shown in FIG. 2, a preferred set of contemplated methods 200 for making a pocketed bread bun with a balloon includes five main steps: Step 210placing a balloon inside a portion of bread dough; Step 220inflating the balloon, preferably using compressed air; Step 230cooking the portion to produce an at least partially cooked bun; Step 240deflating the balloon and removing the balloon from the bun; Step 250cutting the bun into at least a first piece having a first cavity and a second piece having a second cavity.

(24) FIG. 3 shows an embodiment of a device 300 that can be used to produce a pocketed bread bun. A tube 310 is inserted into a portion of bread dough 320, preferably to the center of the bread dough 320. The device 300 comprises a housing 330 that has an expandable mold 340 and at least one mechanical arm 350 connected to the mold 340. The portion of bread dough 320 is placed inside the mold 340 that is inside the housing 330. Alternatively, one end of the tube 310 is located inside the mold 340 before a portion of dough is placed inside the mold 340, and the tube 310 can be inserted into the portion 320 while the portion 320 is placed inside the mold 340.

(25) As compressed air is supplied through the tube 310 into the portion of bread dough 320, the volume of the bread dough 320 expands, due to the formation of an air pocket 321 inside the bread dough 320. The volume of the mold 330 also expands, but is controlled by at least one arm 350, so that the bread dough 320 inside the mold 330 does not expand unevenly or excessively, which may cause the bread dough 320 to rupture.

(26) Cooking can be performed inside the housing 330 by heating the housing 330 to a desirable cooking temperature. In preferred embodiments, the dough imbedded with the insert is baked in an oven at temperatures under which bread dough 320 can at least partially harden, but less than 250 C. to prevent excessive crusting and bubbling. After cooking, the bread dough 320 is removed from the housing 330 and from the tube 310. Alternatively, cutting can be performed while the bread dough 320 is still inside the housing 330. The bread dough 320 is cut along line 322 into at least two pieces (323 and 325). One piece 323 has a cavity 324, and the other piece 325 also has a cavity 326. Preferably, line 322 is off the center so that the volume of one cavity 324 at least 50% larger than the volume of the other cavity 326.

(27) FIG. 4 shows an embodiment of a device 400 that can be used to produce a pocketed bread bun with the addition of an expandable object 405. Contemplated expandable objects include a balloon, or an expandable ball. The expandable object 405 is connected to one end of a tube 410 and is placed inside a portion of bread dough 420. The portion 420 is then placed inside an expandable mold 440 inside a housing 430. Alternatively, the tube 410 with the expandable object 405 is already inside the housing 430 before the portion of bread dough 420 is placed inside the housing 430.

(28) As compressed air is supplied through the tube 410 into the expandable object 405, the volume of the expandable object 405 expands inside the portion of bread dough 420, causing the volume of the bread dough 420 to expand. The volume of the mold 430 also expands, but is controlled by at least one arm 450, so that the bread dough 420 inside the mold 430 does not expand unevenly or excessively, which may cause the bread dough 420 to rupture. Cooking can be performed inside the housing 430 by heating the housing 430 to a desirable cooking temperature, so that the bread dough 420 can at least partially harden.

(29) After cooking, the expandable object 405 reduces its size so that it can be removed from the bread dough 420. The space used to be occupied by the expandable object 405, i.e., air pocket 421, now becomes a hollow center inside the bread dough 420. The bread dough 420 is then removed from the housing 430 and is cut along line 422 into at least two pieces (423 and 425). One piece 423 has a cavity 424, and the other piece 425 also has a cavity 426. Preferably, line 422 is off the center so that the volume of one cavity 424 at least 50% larger than the volume of the other cavity 426. Alternatively, cutting can be performed while the bread dough 420 is still inside the housing 430.

(30) FIG. 5 is an embodiment of a device 500 that can be used to simultaneously produce multiple pocketed buns. The device 500 has multiple molds (e.g., 530), for example, ten molds shown in this particular embodiment. A tube 510 connects the mold 530 with an air source 501 (e.g., air compressor or gas cylinder) that is preferably and advantageously located in the center, so that the least amount of tube 510 needs to be used. The molds (e.g., 530) are housed inside a chamber 550, which can be stacked on top another similar or identical chamber to utilize space for maximum efficiency.

(31) FIG. 6 is an embodiment of a multi-level device 600 with that can be used to simultaneously produce multiple pocketed buns. Device 600 can comprise multiple chambers 550 in FIG. 5, with one chamber stacked on top another. In this particular embodiment shown, eight chambers (620-690) are stacked one on top of another. Alternatively, device 600 can comprise a shelf having multiple floors to support the chambers. A heat source 610 is strategically positioned at the bottom floor of the device 600, since heat (e.g., hot air or hot steam) travels up naturally. It is contemplated that the device 600 can have a water container to supply water (i.e., moisture) for cooking.

(32) It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
