- the cross-sections shown herein are merely illustrative, and should not be viewed as limiting. Such cross-sections are preferably polygon shaped. Such cross-sections are more preferably equi-angular polygons such as: triangle, square, pentagon, hexagon, heptagon, or octagon. Other shapes which provide brand-identification are suitable.
- a bun is formed having a pair of inner chambers.
- This embodiment is useful for building a three-layer sandwich, such as bun-filling-bun-filling-bun, as is common at some fast food restaurants.
- An example of this embodiment is shown in FIGS. 15 and 16 .
- pan 10 includes a pair of male molds 30 without a divider between them such that a bun 12 is formed having a pair of cavities.
- the dimensions shown in FIG. 16 are merely illustrative, the dimensions of bun 12 (such as the thickness of wall 14 or the relative size of cavity 16 ) may be varied according to the type of bun which is desired. The same can be said for a bun formed having a single cavity.
- pan 10 forms a bun where both the outer surface and the cavity surface of bun 12 has a browned surface.
- Most buns for example a common hamburger bun, have a browned outer surface, but the inner surface is not browned, but is formed by splitting the bread open.
- the present bun 12 includes an inner cavity having a browned surface such that when a filling is placed in the bun the filling contacts a browned surface and the browned surface serves to minimize the bread becoming soggy by resisting absorption of moisture from the filling. In this way, pan 10 bakes a bun 12 which resists becoming soggy.
- the outer surface of bun 12 is browned either by direct contact from heated air when baking (such as is the case at the open top of pan 10 ), or by conductive heat transferred from pan 10 to the bun.
- Base plate 20 includes apertures 28 through which heated air enters the internal cavity of male mold 30 , such that male mold 30 is heated during baking so as to brown the inner cavity 16 of bun 12 . Browning the inner cavity 16 of bun 12 provides the beneficial effect of forming a filling-accepting portion of bun 12 which is resistant to becoming soggy.
- Pan 10 is formed from a material sufficient at least to withstand the heat of baking, to retain shape when baking, and to transfer heat to brown bun 12 when baking. Such materials include, but are not limited to, aluminum, steel and other metals, silicone, tempered glass, ceramic, or composite. Any of such materials may include a non-stick coating. Pan 10 is formed having an open top wherein the open top allow gases to escape from the pan when bun is being baked.
- FIGS. 17-21 An embodiment of the pan 80 is shown in FIGS. 17-21 .
- the dough 78 as seen in FIG. 21 , is formed and baked over a base plate 82 with a male mold portion 84 .
- the pan 80 includes a housing 86 that has an open top 88 and an aperture 90 for receiving the male mold portion 84 .
- the pan 80 further includes a top cap 92 .
- the top cap 92 has a wing plate 94 that extends into the housing 86 .
- the base plate 82 , housing 86 , and top cap 92 enclose the pan 80 to constrain the dough as it is being baked.
- the assembled pan 80 and enclosed volume are shown in the section view FIG. 19 .
- the base plate 82 has the male mold portion 84 that extends from a planar portion 96 .
- the male mold portion 84 and planar portion 96 form a continuous surface, shown in FIGS. 17 and 20 .
- the outer surface of the male mold portion 84 is designed to be in direct contact with dough 78 and baked bread, as the outside shape is designed to form the inside pocket of a bun as it is baked.
- the male mold portion 84 is shown as tapered, also known as draft, which assists the male mold portion 84 to release the dough once it is baked into a bun.
- At the end of the male mold portion 84 is a terminal end surface 98 .
- the terminal end surface 98 is spaced from the planar portion 96 by a first distance.
- the terminal end surface 98 can have different shapes, based on the style of bun and anticipated ingredients for the bun. As previously described, the male mold portion 84 is smallest at the terminal end surface 98 . While the embodiment shown is tapered, it is anticipated that the male mold portion 84 is straight.
- the base plate 82 particularly the planar portion 96 , has optional ejection tabs 110 , 112 . Each ejection tab 110 , 112 extends outwardly from the perimeter edge 114 of the planar portion 96 .
- the ejection tabs 110 , 112 are used by automation equipment to grasp the base plate 82 and remove it from the housing 86 .
- the ejection tabs 110 , 112 are shown as extending outwardly, but other features are anticipated to assist automation equipment.
- the housing 86 has a continuous upstanding wall 100 with a top edge 102 and a bottom wall 104 with the aperture 90 .
- the top edge 102 is shown as a smooth continuous edge.
- the bottom wall 104 is continuously attached where it intersects the upstanding wall 100 .
- the bottom wall 104 has an aperture 90 that is sized to receive the male mold portion 84 .
- the size and shape of the aperture 90 closely match the male mold portion 84 when the base plate 82 is mated with the housing 86 . Matching the sizes closely between the aperture 90 and the male mold portion 84 allow dough to be inserted into the mold without dangers of leakage as the dough is baked.
- the upstanding wall has an inside surface 106 and an outside surface 108 .
- the housing 86 further includes ejection tabs 120 .
- the ejection tabs 120 allow automation equipment to grasp the housing 86 to allow baked bread to be ejected.
- the ejection tabs 120 are shown as extending outwardly from the outer surface of the continuous upstanding wall 100 but other devices or features that allow for ejection are contemplated. Further, it is contemplated that the housing 86 is formed from two or more parts that would separate to allow baked bread to be more easily removed from the pan 80 . A housing 86 with the ability to separate would also allow more complex shapes of bread to be baked without concern of removing baked bread from the pan 80 .
- the housing 86 may have a tapered portion adjacent the top edge 102 to allow positioning error without mechanical interference when the top cap 92 is inserted. The distance between the top edge and the bottom wall is greater than the distance between the terminal end surface 98 and the planar portion 96 . When inserted into the housing 86 , the terminal end surface 98 is below the top edge 102 .
- the top cap 92 has a planar portion 122 and the wing plate 94 , as in FIG. 17 , is attached to and extends from one side of the planar portion 122 .
- the wing plate 94 has an outwardly facing surface 124 , as in FIG. 21 , that is complimentary to the terminal end surface 96 of the male mold portion 84 . As assembled into the complete pan 80 , the terminal end surface 96 is spaced from the outwardly facing surface 124 .
- the complimentary nature of these surfaces allows for flexibility of the shape of the bun while still retaining more uniform wall thickness in a baked bun. This is visible in FIGS. 19, 21 .
- the wing plate 94 is spaced from the planar portion 122 with spacing walls 130 , 132 , see FIG. 19 .
- the spacing walls 130 , 132 are optional and only serve to space the wing plate 94 from the planar portion 122 .
- the wing plate 94 has a middle section 134 , a side section 136 and a second side section 138 .
- the side sections 136 , 138 are obliquely angled with respect to the middle section. These sections form the outwardly facing surface 124 , in FIG. 19 .
- the wing plate 94 further includes a perimeter edge 140 .
- the perimeter edge 140 is sized and shaped to be in close proximity or contact with the inside surface 106 of the continuous perimeter wall 100 when the wing plate 94 is inserted into the housing 86 . It is contemplated that the wing plate 94 is flat, curved, or other shape.
- the top cap 92 and outwardly facing surface 124 may be formed similarly to the base plate and have a continuous surface.
- the stuffing ram 150 has a continuous wall 152 with a leading edge 154 .
- the ram 150 is open to allow air to move through the ram 150 as it is being inserted or withdrawn. As shown in FIG. 21 , the leading edge 154 presses through the dough, driving it downwardly.
- the continuous wall 152 is shaped to temporarily reside between the male mold portion 84 and the continuous upstanding wall 100 .
- the stuffing ram 150 is used to drive dough 78 down into the area of the pan 80 that is nearest the bottom wall 104 . It is contemplated that pressure or vacuum will assist or be used to move the dough to fill the mold.
- the ram 150 includes a gripping feature 156 that is attached to opposing sides of the continuous wall 152 .
- the gripping feature is used to allow automation equipment to insert and remove the ram 150 .
- the ram 150 is used only to insert the dough and is not present for the baking process.
- the gripping feature 156 utilizes different features that would be used by automation equipment, such as tabs, through-holes, or gripping areas.
- the user starts with a clean housing 86 and inserts the base plate 82 into the aperture 90 .
- Dough 78 is then dispensed above the open top 88 , where it drops onto the male mold portion, typically the terminal end surface 96 .
- the dough 78 may fill in the voids near the bottom wall 104 , based on the size of the mold and viscosity of the dough 78 .
- the optional stuffing ram 150 is inserted, driving the dough 78 downwardly. This step is shown in FIG. 21 .
- the ram 150 is removed and the top cap 92 is installed, where the perimeter edge 140 is in close proximity or touching the inside surface 106 of the continuous perimeter wall 100 .
- the assembly of these parts creates a mostly closed cavity where the dough will expand and fill as it bakes. Gaps between adjacent parts allow gases to escape.
- the top cap 92 and base plate 82 are removed from the housing 86 . This allows the baked bread to be ejected from the housing. Once the parts are cleaned, the pan 80 is ready for another baking cycle. As is well known in the art, it is common to apply a non-stick coating or surface on any part that may contact a food product, particularly one that is baked.

The complimentary outer surface forms a more consistent thickness of a baked item. The housing has a bottom surface with an aperture in the bottom to receive the male mold portion. The bottom surface acts to eject the baked item from the pan as the male mold portion is removed from the pan. The top portion can be formed with a continuous surface or have a wing plate that is spaced from a planar portion.
Description
- This application is a divisional of U.S. patent application Ser. No. 15/245,956, filed Aug. 24, 2016, which is a Continuation-in-Part of U.S. application Ser. No. 14/152,074 filed Jan. 10, 2014, which is a divisional of U.S. application Ser. No. 13/553,868, filed Jul. 20, 2012, issued as U.S. Pat. No. 8,870,151 on Oct. 28, 2014, the disclosures of which are hereby incorporated by reference.
- A typical sandwich is formed having a filling disposed between two pieces of bread. A hamburger is one common sandwich, with a ground beef patty, vegetables and condiments disposed between an upper and lower bun. Sometimes the bread is hinged, such as is used with a hotdog or sausage. The common failing of these types of sandwiches is that they can be difficult to eat tidily, especially when on the go—the sandwich filling can leak out of the bread while being eaten. As such an improved bun is needed for containing sandwich filling. The disclosure provided herein describes an improved pan for baking a bun suitable for use in making a variety of sandwiches (including, but not limited to, hotdogs, sausages, hamburgers, sub sandwiches, loose meat sandwiches, among many others).
- The present disclosure describes a pan for preparing an improved bun suitable for making various types of sandwiches. The pan described herein is composed of a base plate, a housing, an ejector plate, and a divider. The pan, when assembled, is shaped to form a pocket bun therein. The pan is designed to be disassembled in a way to allow ready ejection of the pocket bun from the pan.
- The pan may include a single chamber for producing a single bun, or multiple chambers for producing multiple buns from a single pan. One chamber may include a single male mold for producing a bun having a single cavity, or multiple male molds for producing a bun having multiple cavities. The divider separates the chambers and may include openings to allow buns in adjacent chambers to form a baked connector therebetween for holding the buns together during packaging.
- The pan of the present disclosure includes further improvements over previous pans, including providing a pan with means for ejecting deep-draw goods from the pan such as through a pneumatic system or use of ejection pins. In one configuration, the pan of the present disclosure produces a bun having a plurality of cavities, such that food stuffs are independently insertable into each cavity. In an additional configuration, the shape of either the exterior of the bun or the cavity of the bun is formed with a distinctive shape so as to provide unique brand-identifying capabilities. An optional top with a wing plate can help to form a portion of the outside to cause the bun to have a more defined outer shape and a controlled wall thickness.

pan 10 suitable for preparing apocket bun 12. Pocketbun 12 is a molded object one embodiment of which is shown inFIG. 16 , such as a food product or bun, formed having awall 14 which defines a cavity 16 (other embodiments ofbun 12 are shown in side-view inFIGS. 4, 6, 11, 12, and 15 , whereFIG. 16 shows a two-cavity bun, and the remaining figures show single-cavity buns). Anopening 18 is formed throughwall 14 and allows access tocavity 16.Cavity 16 and opening 18 together form an open mouth inpocket bun 12, withcavity 16 suitable for carrying food products, such as a hamburger, a hotdog, cold cuts, or any other food products and related condiments and dressings. The present disclosure is directed topan 10, any references topocket bun 12 should not be seen as limiting the uses ofpan 10. It is understood thatbun 12 formed inpan 10 is suitable for carrying a variety of sandwich fillings, and any reference to a specific type of filling is merely illustrative and does not limit the use of the bun. For example, any reference to hotdogs is only to illustrate the general shape of the bun, not to limit the bun from being used with other types of fillings. - As described herein,
pan 10, and associated parts described in detail below, are referred to as having upper and lower ends. These designations are for ease of reference herein, with the upper end referring generally to the open top ofpan 10, and the lower end referring generally to the base ofpan 10 opposite the open top. It is understood that as used,pan 10 is positionable in any number of orientations, and as such any reference to upper and lower is not seen as limiting. - Pan 10 is formed from a group of nestable parts: a
base plate 20, ahousing 22, anejection plate 24 and adivider 26, as shown assembled inFIG. 1 and in exploded view inFIG. 2 .Base plate 20 is a generally flat plate having an aperture 28 passing therethrough and spaced inwardly from anouter edge 36. Amale mold 30 extends from atop side 32 ofbase plate 20.Male mold 30 circumscribes aperture 28, such thatmale mold 30 defines acavity 34 having an opening defined by aperture 28 (cavity 34 shown inFIG. 4 ).Male mold 30 is preferably tapered such that a cross-section ofmale mold 30 taken parallel to andproximate base plate 20 is larger than a cross-section ofmale mold 30 taken near the upper end.Male mold 30 is tapered to aid in ejectingbun 12 frompan 10. As shown inFIGS. 1-3 ,male mold 30 has a generally rectangular cross-section, though other cross-sections are suitable, see, for example,FIGS. 5-8 (round cross-section),FIG. 9 (octagon cross-section), andFIG. 10 (oval cross-section).Base plate 20 may include a single aperture 28/mold 30 combination, such as for preparing asingle pocket bun 12, or alternatively may include an array of aperture 28/mold 30 combinations (as shown inFIG. 2 ), such as for preparingmultiple pocket buns 12 using asingle pan 10, or for preparing asingle bun 12 having multiple cavities 16 (as shown inFIG. 15 ). -
Housing 22, as shown inFIG. 2 , is formed having anupright wall 38 defining an interior space, with alip 40 extending inwardly from and inscribing the lower end ofupright wall 38. Whenpan 10 is assembled,lip 40 overliesbase plate 20. As shown inFIGS. 3 and 4 ,upright wall 38 is tapered such that the upper end is wider than the lower end, to ease removal ofpocket bun 12 frompan 10. A guide 42 is positioned on the interior face ofupright wall 38, with the guide formed from afirst rail 44 and asecond rail 46.First rail 44 is positioned generally vertically, andsecond rail 46 is offset from, and generally parallel tofirst rail 44. 44, 46 are offset from one another such that aRails gap 48 is formed therebetween. The embodiment ofhousing 22 shown inFIG. 2 includes a pair of guides 42 positioned on facing surfaces ofupright wall 38. In other embodiments, the number and positioning of guides 42 is variable depending on the number and positions of the aperture 28/mold 30 pairs ofbase 20. In additional embodiments, guides 42 are omitted fromhousing 22. It is contemplated thatbase 20 includesnotches 37, such thatbase 20 is alternatively positionable sandwiched betweenhousing 22 andejector plate 24 withnotches 37 locatingbase 20relative housing 22. -
Ejection plate 24 is defined as a generally flat plate having anouter edge 50. Withpan 10 assembled,ejection plate 24 overlieslip 40 ofhousing 22. Anotch 52 forms an indentation inedge 50, withnotch 52 sized to straddle guide 42 whenpan 10 is assembled, thereby notch 52 locatesejection plate 24relative housing 22, as shown inFIG. 3 .Ejection plate 24 includes anaperture 54 formed therethrough,aperture 54 is sized at least as large as the largest cross-section ofmold 30, such thataperture 54 encirclesmold 30 whenpan 10 is assembled. -
Divider 26 is defined as an upright plate overlyingejection plate 24 and subdividing the interior ofhousing 22 into multiple chambers. In the embodiments shown inFIGS. 2 and 8 divider 26 is X-shaped, with four plates joined together at the intersection formed therebetween. Withpan 10 assembled, anouter edge 56 ofdivider 26 is located atgap 48 betweenfirst rail 44 andsecond rail 46 of guide 42, such that guide 42 retainsdivider 26 at a specified position withinhousing 26.Divider 26 includes anoptional gap 58 formed at the bottom edge ofdivider 26.FIGS. 3 and 7 show a top view ofpan 10 as assembled, wheredivider 26 is used to subdivide the pan into four quadrants, with each quadrant forming a chamber suitable for baking apocket bun 12.Gap 58 provides an opening between adjacent chambers to allowadjacent pocket buns 12 to be joined together, such as to aid in keeping groups ofpocket buns 12 together during processing or shipping.Gap 58 may be positioned at any of many suitable positions ondivider 26, such as at the outer corners ofdivider 26 or at the intersection between the plates, or spaced between the corners and intersection as is shown inFIG. 2 . It is contemplated thatgap 58 may be omitted, thereby providing apan 10 which completely segregatesbuns 12 - It is contemplated, such as is shown in
FIGS. 13 and 14 , thatdivider 26 is shaped other than as an X to form buns of different shapes. It is also contemplated thatdivider 26 may be omitted and the resulting buns may be sliced into individual buns in a separate step. It is contemplated thatgap 58 is omitted such thatdivider 26 forms a complete partition between adjoining chambers. -
FIG. 3 is a top view ofpan 10 showingejection plate 24 overlyinglip 40 of housing 22 (lip 40 shown in dotted line).Notch 52 ofejection plate 24 locatingejection plate 24 inhouse 22 44, 46.relative guide rails Male molds 30 are shown extending up throughejection plate 24. It is contemplated thatejection plate 24 may be omitted. -
FIG. 4 shows a side view ofpan 10.Pocket bun 12 is shown inpan 10.FIG. 4 shows how the constituent parts ofpan 10 stack together, withdivider 26overlying ejection plate 24,ejection plate 24 overlyinglip 40 ofhousing 22, andlip 40overlying base 20.Male mold 30 extends upwardly throughejection plate 24 intohousing 22. - Referring now to
FIGS. 5-8 , in oneembodiment pan 10 is shaped to form abun 12 suitable for carrying a hotdog and associated condiments. As will be appreciated by comparingFIG. 1 andFIG. 5 , each embodiment includes the same constituent parts:base 20,housing 22,ejection plate 24 anddivider 26, the main difference being the relative dimensions and shape of the parts. For example,housing 22 ofFIG. 5 is generally taller than that ofFIG. 1 to allow for the forming of a long bun shaped to carry a hotdog. Similarly,male mold 30 ofFIG. 5 has a circular cross-section to accommodate a hotdog. -
FIG. 8 shows an exploded view of the constituent parts of thepan 10 ofFIG. 5 .FIG. 8 showshousing 22 andlip 40, withlip 40 contoured to match the shape ofmale molds 30.Base 20 includesspacers 60 which serve to locatehousing 22 onbase 20.Spacers 60 are raised bosses or strips extending from the surface ofbase 20 which contact the outer wall ofhousing 22 whenpan 10 is assembled.FIG. 1 shows an embodiment ofpan 10 which omitsspacers 60. It is envisioned thatpan 10 ofFIG. 1 could be modified to include aspacer 60 by enlarging the dimensions ofbase 20. Likewise, it is envisioned thatpan 10 ofFIG. 8 could be modified to omitspacer 60. -
FIG. 6 shows a cross-sectional side view of the embodiment ofpan 10 showing how the constituent parts overly one another in assembled form.FIG. 6 is comparable toFIG. 4 . Similarly,FIG. 7 is comparable toFIG. 3 in showing a top view of the respective embodiments ofpan 10. -
FIGS. 9 and 10 show alternative shapes ofmale mold 30.FIG. 9 showsmale mold 30 having an octagon-shaped cross-section.FIG. 10 showsmale mold 30 having an oval-shaped cross-section. As is clear fromFIGS. 9 and 10 ,male mold 30 is formable in any one of many possible cross-sectional shapes, which in turn forms the internal cavity ofpocket bun 12 in the corresponding shape. As such, the shape ofmale mold 30 can be customized to allow for a specific type of food, or to allow for distinctive marketing or branding. The shape ofmale mold 30 may be customized on either the hamburger or hotdog accommodating bun pans. The cross-sections shown herein are merely illustrative, and should not be viewed as limiting. Such cross-sections are preferably polygon shaped. Such cross-sections are more preferably equi-angular polygons such as: triangle, square, pentagon, hexagon, heptagon, or octagon. Other shapes which provide brand-identification are suitable. -
FIG. 11 shows a sectional side view ofpan 10, showing an auto-ejection system having ejection pins 62. Ejection pins 62 pass through apertures inbase 20 such that when actuated, ejection pins 62 apply a force toejection plate 24, to forcebun 12 away frompan 10. Ejection pins 62 may be mechanically, pneumatically, electrically, manually, or otherwise actuated. Alternatively,ejection plate 24 is omitted and ejection pins 62force housing 22 away frombase 20, andhousing 22 urgesbun 12 out ofpan 10. It is contemplated thatbase plate 20 is carried abovelip 40 ofhousing 22, such thatpin 62, when actuated, forcedbase 20 up and away fromhousing 22. Additionally, it is contemplated thatpin 62, when actuated,contacts bun 12 directly, causingbun 12 to come free frompan 10. -
FIG. 12 shows a sectional side view ofpan 10 having anair manifold 64 for providing a pneumatic release system to pan 10, whereby air is used to forcebun 12 free frompan 10.Manifold 64 is in fluid communication with apertures inmale mold 30, such that when activated,air forces bun 12 away frompan 10. It is contemplated thatejector plate 24 may be omitted wheremanifold 64 is used to ejectbun 12 frompan 10. -
FIGS. 13 and 14 show alternative shapes ofdivider 26, such as to form apocket bun 12 having an octagon-shaped outer cross-section (as inFIG. 13 ), or apocket bun 12 having an oval-shaped outer cross-section (as inFIG. 14 ). The shape ofdivider 26 may be selected to yield the outer cross-section desired for a givenpocket bun 12. The outer cross-section and cavity cross-section ofpocket bun 12 may each be independently selected to yield apocket bun 12 having desired characteristics, such as for brand identification or similar distinctive aesthetic enhancement ofbun 12. The cross-sections shown herein are merely illustrative, and should not be viewed as limiting. Such cross-sections are preferably polygon shaped. Such cross-sections are more preferably equi-angular polygons such as: triangle, square, pentagon, hexagon, heptagon, or octagon. Other shapes which provide brand-identification are suitable. - In one embodiment, a bun is formed having a pair of inner chambers. This embodiment is useful for building a three-layer sandwich, such as bun-filling-bun-filling-bun, as is common at some fast food restaurants. An example of this embodiment is shown in
FIGS. 15 and 16 . Here,pan 10 includes a pair ofmale molds 30 without a divider between them such that abun 12 is formed having a pair of cavities. The dimensions shown inFIG. 16 are merely illustrative, the dimensions of bun 12 (such as the thickness ofwall 14 or the relative size of cavity 16) may be varied according to the type of bun which is desired. The same can be said for a bun formed having a single cavity. - One advantage of
bun 12 formed bypan 10 over prior art breads is thatpan 10 forms a bun where both the outer surface and the cavity surface ofbun 12 has a browned surface. Most buns, for example a common hamburger bun, have a browned outer surface, but the inner surface is not browned, but is formed by splitting the bread open. Thepresent bun 12 includes an inner cavity having a browned surface such that when a filling is placed in the bun the filling contacts a browned surface and the browned surface serves to minimize the bread becoming soggy by resisting absorption of moisture from the filling. In this way, pan 10 bakes abun 12 which resists becoming soggy. - The outer surface of
bun 12 is browned either by direct contact from heated air when baking (such as is the case at the open top of pan 10), or by conductive heat transferred frompan 10 to the bun.Base plate 20 includes apertures 28 through which heated air enters the internal cavity ofmale mold 30, such thatmale mold 30 is heated during baking so as to brown theinner cavity 16 ofbun 12. Browning theinner cavity 16 ofbun 12 provides the beneficial effect of forming a filling-accepting portion ofbun 12 which is resistant to becoming soggy. -
Pan 10 is formed from a material sufficient at least to withstand the heat of baking, to retain shape when baking, and to transfer heat tobrown bun 12 when baking. Such materials include, but are not limited to, aluminum, steel and other metals, silicone, tempered glass, ceramic, or composite. Any of such materials may include a non-stick coating.Pan 10 is formed having an open top wherein the open top allow gases to escape from the pan when bun is being baked. - An embodiment of the
pan 80 is shown inFIGS. 17-21 . In this embodiment, thedough 78, as seen inFIG. 21 , is formed and baked over abase plate 82 with amale mold portion 84. As shown inFIG. 17 . thepan 80 includes ahousing 86 that has an open top 88 and anaperture 90 for receiving themale mold portion 84. Thepan 80 further includes atop cap 92. Thetop cap 92 has awing plate 94 that extends into thehousing 86. Thebase plate 82,housing 86, andtop cap 92 enclose thepan 80 to constrain the dough as it is being baked. The assembledpan 80 and enclosed volume are shown in the section viewFIG. 19 . - The
base plate 82 has themale mold portion 84 that extends from aplanar portion 96. Themale mold portion 84 andplanar portion 96 form a continuous surface, shown inFIGS. 17 and 20 . The outer surface of themale mold portion 84 is designed to be in direct contact withdough 78 and baked bread, as the outside shape is designed to form the inside pocket of a bun as it is baked. Themale mold portion 84 is shown as tapered, also known as draft, which assists themale mold portion 84 to release the dough once it is baked into a bun. At the end of themale mold portion 84 is aterminal end surface 98. Theterminal end surface 98 is spaced from theplanar portion 96 by a first distance. Theterminal end surface 98 can have different shapes, based on the style of bun and anticipated ingredients for the bun. As previously described, themale mold portion 84 is smallest at theterminal end surface 98. While the embodiment shown is tapered, it is anticipated that themale mold portion 84 is straight. Thebase plate 82, particularly theplanar portion 96, has 110, 112. Eachoptional ejection tabs 110, 112 extends outwardly from theejection tab perimeter edge 114 of theplanar portion 96. The 110, 112 are used by automation equipment to grasp theejection tabs base plate 82 and remove it from thehousing 86. The 110, 112 are shown as extending outwardly, but other features are anticipated to assist automation equipment.ejection tabs - The
housing 86 has a continuousupstanding wall 100 with atop edge 102 and abottom wall 104 with theaperture 90. Thetop edge 102 is shown as a smooth continuous edge. Thebottom wall 104 is continuously attached where it intersects theupstanding wall 100. As previously described, thebottom wall 104 has anaperture 90 that is sized to receive themale mold portion 84. The size and shape of theaperture 90 closely match themale mold portion 84 when thebase plate 82 is mated with thehousing 86. Matching the sizes closely between theaperture 90 and themale mold portion 84 allow dough to be inserted into the mold without dangers of leakage as the dough is baked. The upstanding wall has aninside surface 106 and an outside surface 108. Thehousing 86 further includesejection tabs 120. Theejection tabs 120 allow automation equipment to grasp thehousing 86 to allow baked bread to be ejected. Theejection tabs 120 are shown as extending outwardly from the outer surface of the continuousupstanding wall 100 but other devices or features that allow for ejection are contemplated. Further, it is contemplated that thehousing 86 is formed from two or more parts that would separate to allow baked bread to be more easily removed from thepan 80. Ahousing 86 with the ability to separate would also allow more complex shapes of bread to be baked without concern of removing baked bread from thepan 80. Thehousing 86 may have a tapered portion adjacent thetop edge 102 to allow positioning error without mechanical interference when thetop cap 92 is inserted. The distance between the top edge and the bottom wall is greater than the distance between theterminal end surface 98 and theplanar portion 96. When inserted into thehousing 86, theterminal end surface 98 is below thetop edge 102. - The
top cap 92 has aplanar portion 122 and thewing plate 94, as inFIG. 17 , is attached to and extends from one side of theplanar portion 122. Thewing plate 94 has an outwardly facingsurface 124, as inFIG. 21 , that is complimentary to theterminal end surface 96 of themale mold portion 84. As assembled into thecomplete pan 80, theterminal end surface 96 is spaced from the outwardly facingsurface 124. The complimentary nature of these surfaces allows for flexibility of the shape of the bun while still retaining more uniform wall thickness in a baked bun. This is visible inFIGS. 19, 21 . Thewing plate 94 is spaced from theplanar portion 122 with spacing 130, 132, seewalls FIG. 19 . The spacing 130, 132 are optional and only serve to space thewalls wing plate 94 from theplanar portion 122. Thewing plate 94 has amiddle section 134, aside section 136 and asecond side section 138. The 136, 138 are obliquely angled with respect to the middle section. These sections form the outwardly facingside sections surface 124, inFIG. 19 . Thewing plate 94 further includes aperimeter edge 140. Theperimeter edge 140 is sized and shaped to be in close proximity or contact with theinside surface 106 of thecontinuous perimeter wall 100 when thewing plate 94 is inserted into thehousing 86. It is contemplated that thewing plate 94 is flat, curved, or other shape. As shown inFIG. 21 , thetop cap 92 and outwardly facingsurface 124 may be formed similarly to the base plate and have a continuous surface. - Because some dough is more viscous than other dough, a stuffing
ram 150, as inFIG. 20 , may be required. The stuffingram 150 has acontinuous wall 152 with aleading edge 154. Theram 150 is open to allow air to move through theram 150 as it is being inserted or withdrawn. As shown inFIG. 21 , theleading edge 154 presses through the dough, driving it downwardly. Thecontinuous wall 152 is shaped to temporarily reside between themale mold portion 84 and the continuousupstanding wall 100. The stuffingram 150 is used to drivedough 78 down into the area of thepan 80 that is nearest thebottom wall 104. It is contemplated that pressure or vacuum will assist or be used to move the dough to fill the mold. Theram 150 includes agripping feature 156 that is attached to opposing sides of thecontinuous wall 152. The gripping feature is used to allow automation equipment to insert and remove theram 150. As described, theram 150 is used only to insert the dough and is not present for the baking process. It is contemplated that thegripping feature 156 utilizes different features that would be used by automation equipment, such as tabs, through-holes, or gripping areas. - To make baked bread with the
pan 80, the user starts with aclean housing 86 and inserts thebase plate 82 into theaperture 90.Dough 78 is then dispensed above the open top 88, where it drops onto the male mold portion, typically theterminal end surface 96. Thedough 78 may fill in the voids near thebottom wall 104, based on the size of the mold and viscosity of thedough 78. At that point, theoptional stuffing ram 150 is inserted, driving thedough 78 downwardly. This step is shown inFIG. 21 . After the dough is placed into thepan 80 and driven sufficiently downward toward thebottom wall 104, theram 150 is removed and thetop cap 92 is installed, where theperimeter edge 140 is in close proximity or touching theinside surface 106 of thecontinuous perimeter wall 100. The assembly of these parts creates a mostly closed cavity where the dough will expand and fill as it bakes. Gaps between adjacent parts allow gases to escape. - To eject the baked bread, the
top cap 92 andbase plate 82 are removed from thehousing 86. This allows the baked bread to be ejected from the housing. Once the parts are cleaned, thepan 80 is ready for another baking cycle. As is well known in the art, it is common to apply a non-stick coating or surface on any part that may contact a food product, particularly one that is baked. - It is understood that while certain aspects of the disclosed subject matter have been shown and described, the disclosed subject matter is not limited thereto and encompasses various other embodiments and aspects. No specific limitation with respect to the specific embodiments disclosed herein is intended or should be inferred. Modifications may be made to the disclosed subject matter as set forth in the following claims.
