High efficiency in preparing food is especially critical in quick-service restaurants during times of peak sales, such as breakfast, lunch and dinner.
[0063] Examples of cooked food products 16 that apparatus 14 may be used to advantageously hold are scrambled eggs, sausage patties, sausage links, grilled chicken breasts, vegetables and the like. Maintaining bath 22 at a temperature In the range of 150 F to 180 F typically results in a suitably warm food item for consumption by the customer. Generally speaking, a temperature above 150 F is desirable to minimize bacterial growth in bath 22 and food products 16 stored in bag 20.
Alternatively, in other applications bath 22 may be cooled in any suitable manner, such as by a suitable heat exchanging device 26, or cooled by ice placed in bath 22 to reduce its temperature.

[0064] Referring now to FIGS. 3-8, food holding apparatus 14 can be seen in greater detail. Rack 18 has a frame 28 that includes a bottom base 30, a top end 32 and side supports, or columns 36. Frame 28 may also have handles 34 for convenient grasping of rack 18 during transport, and positioning and removing rack 18 from within vat 24. Frame 28 also may have bottom braces 38, column braces 40 and top braces 42, 44 to provide rigidity for frame 28. Rack 18 should have sufficient weight so that the contents of bag 20 do not permit rack 18 to float in bath 22.
[0065] Frame 28 may additionally include a top mounting member 48 pivotably mounted to top brace 44. Mounting member 48 includes bag retaining rods 50, 52 each having a loop 54 at ends 58 to mount mounting member 48 to top brace 44. Loops 54 are formed with dimensions suitable to secure rods 50, 52 to top brace 44, while also allowing pivotable movement of rods 50, 52 about brace 44. The opposite ends 60 of rods 50, 52 may be provided with flat tip sections 62 for facilitating mounting bag 20 onto member 48.
Flat tip sections 62 extend to overlie top brace 42 to limit the downward pivoting motion of rods 50, 52. Rods 50, 52 may be yoked together by a yoke brace 64 so as to cause rods 50, 52 to pivot in unison. Secured to each of bottom braces 38 is a bag bottom retaining rod 66 that may have a retaining ball 68 attached to the free end of each rod 66.
[0066] Bag 20 may be formed with a front sidewall 72 and a rear sidewall 74 that are sealed together along seam 78 at the side edges 80 of bag 20. Bag 20 may also include a.
bottom gusset 82 that is formed at the bottom 76 of bag 20. Gusset 82 has gusset tabs 86 and 88 that may be spread apart to form an expanded bottom for bag 20 to thereby increase the capacity of bag 20. When gusset 82 is expanded, it also acts to space apart sidewalls 72, 74 to allow for more convenient access to the Interior 70 of the bottom portion 76 of bag 20. Bag 20 may be formed from any suitable material, such as a liquid impervious flexible plastic material. Thus, bag 20 provides a watertight container with hollow interior 70 defined by the Inner surfaces 73, 75 of sidewalls 72, 74, respectively, and by the inner surface 77 of gusset 82.

Secured to each of bottom braces 38 is a bag bottom retaining rod 66 that may have a retaining ball 68 attached to the free end of each rod 66.
[0066] Bag 20 may be formed with a front sidewall 72 and a rear sidewall 74 that are sealed together along seam 78 at the side edges 80 of bag 20. Bag 20 may also include a.
bottom gusset 82 that is formed at the bottom 76 of bag 20. Gusset 82 has gusset tabs 86 and 88 that may be spread apart to form an expanded bottom for bag 20 to thereby increase the capacity of bag 20.

Thus, bag 20 provides a watertight container with hollow interior 70 defined by the Inner surfaces 73, 75 of sidewalls 72, 74, respectively, and by the inner surface 77 of gusset 82.
[0067] Bag 20 may be provided with two sleeves 90 for mounting the top portion 91 of bag 20 to frame 28 of rack 18. Top retaining sleeves 90 are formed adjacent the top edges 92 of sidewalls 72, 74, such as by an inward or outward fold of each of sidewalls 72, 74.
After folding over top edges 92, each of edges 92 may be secured to the inner surface of its respective sidewall 72 or 74, such as by heat sealing. For purposes explained later in greater detail, sleeves 90 may also include cut out sections, or voids 94 at the top comers 95 of bag 20.

[0068] To mount bag 20 to frame 28, sleeves 90 are slipped over rods 50, 52.
During the mounting of bag 20, rods 50, 52 can be pivoted upward to allow convenient access to tip sections 62 of rods 50, 52. Tip sections 62 facilitate insertion of rods 50, 52 into sleeves 90 in two ways. First, since rods 50, 52 are only braced at brace 64, rods 50, 52 may be manually squeezed together, or spread apart, as necessary to align tip sections 62 within the opening to sleeves 90. Secondly, flat tip sections 62 have a flat and reduced cross section that facilitates the insertion of rods 50, 52 into the relatively flat openings 96 of sleeves 90.

Secondly, flat tip sections 62 have a flat and reduced cross section that facilitates the insertion of rods 50, 52 into the relatively flat openings 96 of sleeves 90.
[0069] It is noted that rods 50, 52 are preferably spaced approximately 2-1/2 inches apart. This spreads apart sleeves 90 to provide an unobstructed opening 100 at the top 98 of bag 20 for the placement and removal of food product 16 within bag 20.
Thus, utensils, such as food tongs 15e and spoon 15d, may readily pass between rods 50, 52 and into interior 70 of bag 20. Cut out sections 94 allow bag side edges 80 to extend beyond and beneath top braces 42, 44 to form an elongated generally rectangular shaped access opening 100 to bag interior 70 that is unobstructed between top braces 42 and 44.

[0070] Bag 20 is also secured to the bottom portion 99 of frame 28 to prevent upward buoyant movement of bottom portion 76 of bag 20 when placed In bath 22. In one embodiment, bottom portion 76 is provided with bottom restraining sleeves 87 and 89.
Sleeves 87 and 89 may be formed between gusset tabs 86, 88 such as by heat sealing gusset tab 86 to gusset tab 88 at sections 102 and 104. When mounting bag 20 to frame 28, each of sleeves 87 and 89 are slipped over one of retaining balls 68 and onto one of bottom retaining rods 66. Cut out sections 106 at bottom comers 108 of gusset tabs 86, 88, allow the bottom of side edge 80 to extend over and beyond base braces 38.
As best illustrated In FIG. 8, this prevents bottom side edges 80 from bunching up at braces 38 to hinder access to bottom portion 76 of bag 20.

As best illustrated In FIG. 8, this prevents bottom side edges 80 from bunching up at braces 38 to hinder access to bottom portion 76 of bag 20.
[0071] Referring now to FIG. 7, there is illustrated a food product 16 contained within flexible bag 20 mounted on rack 18 prior to rack 18 being submerged in fluid bath 22.
Sidewalls 72, 74 are held spaced apart at bag opening 100 by spaced apart rods 50, 52 positioned within top sleeves 90. Sidewalls 72, 74 depend downwardly from rods 50, 52 in a spaced apart position. The sidewalls 72, 74 may also be maintained in a spaced apart position at bottom portion 76 of bag 20 by spreading out gusset 82 tab sections 86, 88.
With sidewalls 72, 74 of bag 20 spaced apart at top portion 91 and bottom portion 76, the middle section 124 of bag 20 is also spaced apart to provide an open bag interior 70 that is advantageous for quick filling of food product 16.

The sidewalls 72, 74 may also be maintained in a spaced apart position at bottom portion 76 of bag 20 by spreading out gusset 82 tab sections 86, 88.
With sidewalls 72, 74 of bag 20 spaced apart at top portion 91 and bottom portion 76, the middle section 124 of bag 20 is also spaced apart to provide an open bag interior 70 that is advantageous for quick filling of food product 16.
[0072] FIG. 5 Illustrates rack 18 inserted in vat 24. It can be seen that bath 22 produces hydrostatic forces that act upon the outer surfaces 128 of a submerged bag 20.
This force collapses sidewalls 72, 74 together along a sealing section 130 above food 16.
Sidewalls 72, 74 may also collapse against individual pieces of food product 16. This increases heat transfer from bath 22 to food product 16 by increasing the surface area of food product 16 that is directly adjacent hot water bath 22, separated only by bag 20. When placed in bath 22, bottom sleeves 87, 89 act to restrain bag bottom portion 76 to limit the upward movement of bag 20 due to the buoyancy.
This force collapses sidewalls 72, 74 together along a sealing section 130 above food 16.
Sidewalls 72, 74 may also collapse against individual pieces of food product 16. This increases heat transfer from bath 22 to food product 16 by increasing the surface area of food product 16 that is directly adjacent hot water bath 22, separated only by bag 20. When placed in bath 22, bottom sleeves 87, 89 act to restrain bag bottom portion 76 to limit the upward movement of bag 20 due to the buoyancy.
[0073] Thus, bag interior 70 containing food 16 is sealed or substantially sealed from the external environment to keep food product 16 from losing excessive moisture to the external atmosphere as it is stored for periodic withdrawal. Moisture In food product 16 is retained. In addition to maintaining the organoleptic properties, food product 16 can also be kept warm (or cooled, if desired) for an extended period of time as it is stored prior to use in preparing food products with the stored food. If desired, the interior surface or surfaces of bag 20 may be textured or dimpled so that complete closure of bag 20 does not occur, but rather a limited airspace Is provided at least in the area where bag 20 is otherwise sealed to the external atmosphere.
[0074] It can also be seen in FIG. 5 that when bag 20 is in the sealed state, a trough-like area 132 appears above sealed section 130. To remove food product 16, a meal preparer can place a utensil, such as tongs 15e, within trough 132. As tongs 15e are moved downward, sidewalls 72, 74 easily separate sealed section 130 to gain access to food product 16 for removal. Thus, food preparation efficiency is increased by providing a supply of food 16 stored on hand at work station 10 for periodic rapid withdrawal as required for use in assembling a meal.
[0075] It may also be advantageous to have a second or main water vat 138 (FIG. 1) positioned at a remote location in a kitchen such as adjacent the food product cooking area. The second vat 138 may be similar to vat 24, except that It may be wider to accept a plurality of food racks 18. For example, four food racks 18 can be filled with a food 16, such as precooked sausage patties, and submerged in main hot water vat 138 to provide a ready supply of food product 16 stored in a plurality of racks. When the supply of food product 16 is depleted at work station 10, rack 18 can then be transported from main vat 138 to a vat 24 at work station 10, or other similar work stations within the restaurant.
[0076] FIGS. 10-13 illustrate another embodiment of the apparatus for storing a food product 16 that includes a modified frame 150 and a bag 152. Bag 152 is similar to bag 20;
however, one difference is that bag 152 provides an alternate means for securing the bottom portion 154 of bag 152 to frame 150. Another difference is that bottom portion 154 provides increased heat transfer between fluid bath 22 and the interior 158 of bag 152, particularly at the bottom portion 154 of bag 152. Bag 152 includes a front sidewall 160 and a rear sidewall 162. Front sidewall 160 has a top end 164 and a bottom end 168, and an inner surface 170 and outer surface 172. Rear sidewall 162 also has a top end 173 and a bottom end 174, and an inner surface 176 and an outer surface 178. Bag 152 has a gusset 180 having a front gusset tab 182 and a rear gusset tab 184. The bottom and 188 of front gusset tab 182 Is joined to the bottom end 168 of front sidewall 160, and the bottom end 190 of rear gusset tab 184 is joined to the bottom end 174 of rear sidewall 16g. Unlike gusset 82 of bag 20, gusset 180 ofbag 152 and gusset tabs 182 and 184 are not joined together to form sleeves 87, 89.
however, one difference is that bag 152 provides an alternate means for securing the bottom portion 154 of bag 152 to frame 150. Another difference is that bottom portion 154 provides increased heat transfer between fluid bath 22 and the interior 158 of bag 152, particularly at the bottom portion 154 of bag 152. Bag 152 includes a front sidewall 160 and a rear sidewall 162. Front sidewall 160 has a top end 164 and a bottom end 168, and an inner surface 170 and outer surface 172. Rear sidewall 162 also has a top end 173 and a bottom end 174, and an inner surface 176 and an outer surface 178. Bag 152 has a gusset 180 having a front gusset tab 182 and a rear gusset tab 184. The bottom and 188 of front gusset tab 182 Is joined to the bottom end 168 of front sidewall 160, and the bottom end 190 of rear gusset tab 184 is joined to the bottom end 174 of rear sidewall 16g. Unlike gusset 82 of bag 20, gusset 180 ofbag 152 and gusset tabs 182 and 184 are not joined together to form sleeves 87, 89.
[0077] As described below, bag 152, like bag 20, may be formed from a single sheet of material. Bag 152 may also be formed by joining together Individual sheets by any suitable means such as heat sealing. Typically, bag 152 is heat sealed along margins 192 to seal and/or reinforce the edges of bag 152, except for open end 194 of bag 152, as shown in FIG. 10.
[0078] Frame 150, like frame 28, has a base 30, columns 36, and top 32 including mounting member 48. Frame 150 also has a bag support 198 attached to cross braces 38.
Bag support 198 may include sides 200 and top 202. Frame 150 also includes a plurality of mounting members, or balls 196 attached to the frame base 30.
Bag support 198 may include sides 200 and top 202. Frame 150 also includes a plurality of mounting members, or balls 196 attached to the frame base 30.
[0079] FIG. 10 best illustrates bag 152 mounted to frame 150. The sleeves 90 of bag 152 are positioned over mounting member 48 to mount the top portion 204 of bag 152.
The juncture 208 of front gusset tab 182 and rear gusset tab 184 is positioned over bag support top 202. Gusset tabs 182 and 184 depend downwardly to be positioned on opposite sides of support top 202. Front and rear gusset tabs 182, 184 include one or more holes 210 adjacent bottom ends 188, 190, respectively. Holes 210 cooperate with balls 196 to restrain bottom portion 154 of bag 152 to thereby prevent upward buoyant movement of bottom portion 154 of bag 152. Preferably, holes 210 are positioned in the lower margin 212, since lower margin 212 of bag 152 in an area of increased strength, due to the heat sealing of sidewalls 160,162 to gusset tabs 182, 184 respectively.
The juncture 208 of front gusset tab 182 and rear gusset tab 184 is positioned over bag support top 202. Gusset tabs 182 and 184 depend downwardly to be positioned on opposite sides of support top 202. Front and rear gusset tabs 182, 184 include one or more holes 210 adjacent bottom ends 188, 190, respectively. Holes 210 cooperate with balls 196 to restrain bottom portion 154 of bag 152 to thereby prevent upward buoyant movement of bottom portion 154 of bag 152. Preferably, holes 210 are positioned in the lower margin 212, since lower margin 212 of bag 152 in an area of increased strength, due to the heat sealing of sidewalls 160,162 to gusset tabs 182, 184 respectively.
[0080] FIGS. 12 and 13 illustrate the increased heat transfer for bottom portion 154 of bag 152. Gusset tabs 182 and 184 are spaced apart along their entire length to provide greater surface area contact with bath 22. Also, gusset tabs 182, 184 form chambers 218, 220, respectively, where food 16 may be located to be nearer to bath 22, as compared to bag 20. The spaced apart gusset tabs 182, 184 of bag 152 increase circulation between gusset tabs 182, 184 to further increase heat transfer to food 16.
[0081] Referring to FIG. 9, it is schematically illustrated how bag 20 or bag 152 may be formed by folding a single sheet of material 110. Sheet 110 is folded to form sidewalls 72, 74, gusset 82 and sleeves 90 of bag 20. The inner surface 112 of sheet 110 is folded inwardly along line 114 to form front sidewall 72, outwardly folded along line 116 to form gusset 82, and inwardly folded along line 118 to form rear sidewall 74. Top sleeves 90 are formed by inward folds along lines 120. Alternatively, sheet 110 may be folded outwardly along lines 120a and 120b to form sleeves 90.
[0082] In a like manner, sheet 110 can be folded to form bag 152. The inner surface 112 of sheet 110 is folded inwardly along line 114 to form front sidewall 160, outwardly folded along line 116 to form gusset 180, and inwardly folded along line 118 to form rear sidewall 162. Top sleeves 90 are formed by inward, or alternatively outward, folds along lines 120a and 120b. Additionally, margins 192 may be heat sealed and provided with holes 210.
Bag 152 may also be provided with voids or cut out sections 222 to complete bag 152.
Bag 152 may also be provided with voids or cut out sections 222 to complete bag 152.
[0083] In another embodiment of the invention, food holding apparatus 14 uses alternate means to secure bag 20 to frame 28, or to secure bag 152 to frame 150. As shown in FIG. 6, a clamp 134 is utilized to clamp bag 20 to frame 28. One or more clamps 134 may be used at frame base 30, side support 36, and/or top 32. By using clamps 134, lower sleeves 87, 89 are not required for bag 20. Bag 20 could also be held down by placing a weight (not shown) in the bottom of bag 20, or attaching a weight to the bottom of bag 20. By using clamps 134 to clamp the top of bag 20 to rods 50, 52, upper bag sleeves 90 could also be eliminated. Likewise, clamps 134 may be utilized in place of holes 210 and/or sleeves 90 of bag 152 to mount bag 152 to frame 150.
[0084] Apparatus 14 of the present invention need not be limited to the use of storing food products at work station 12. Apparatus 14 may be situated at any other desirable location. For example, apparatus 14 may be located at a buffet table and used to maintain the freshness of the food product at a buffet serving table. Apparatus 14 may also be provided with a heating device 26 for a vat 24 positioned at a buffet table, to heat or cool bath 22 and food product 16.
[0085] While the invention has been described with respect to certain preferred embodiments, as will be appreciated by those skilled in the art, it is to be understood that the invention is capable of numerous changes, modifications and rearrangements and such changes, modifications and rearrangements are intended to be covered by the following claims.
