TECHNICAL FIELD

This disclosure relates to a pizza delivery system, including a frozen pizza crust and a bakeable tray and methods of making and using.

BACKGROUND

Delivered pizza is pre-cut into individual serving pieces, and is delivered in a disposable box. Thus, with delivered pizza, no tools are required to cut the pizza, and no dishes are needed for holding the pizza. The box may be disposed of, and there are no additional serving trays that must be washed and put away. With typical frozen pizzas, the pizza must be transferred to a tray, either for cooking or for serving. In addition, the frozen pizza, after cooking, must then be cut using a pizza cutter or other cutting instruments. The tray and the cutter must then be washed.

The inventors have recognized that it would be desirable to have a frozen pizza that had the convenience of delivery pizza.

FIG. 5 is a perspective view of a portion of the frozen pizza of FIG. 1, outside of the tray.

DETAILED DESCRIPTION

In FIG. 1, a pizza and tray combination is illustrated at reference numeral 10. The combination includes a bakeable tray 12 (see also FIGS. 2-4) that is designed to hold and provide a cooking instrument for a frozen pizza 14. In FIG. 5, it can be seen that the frozen pizza 14 includes a crust 16 and toppings 18. The toppings 18 can be any one of or several of the following: sauces, cheese, meats, vegetables, fruits, spices, condiments, fats such as butter or oil, and other miscellaneous toppings that may be desirable for consumption. The pizza 14 is frozen such that it, along with the tray 12, may be directly moved from a freezer into an oven for cooking.

Preferably, the tray 12 is constructed of a material that allows it to be easily disposable. One such material is paperboard. Other useable materials include crystalline polyethylene terephthalate (CPET), aluminum such as aluminum foil, corrugate, or others. A bakeable single-use disposable tray allows the tray 12 to be heated in an oven, provide a cooking instrument for the pizza 14, and then be disposed of after the pizza is removed from the tray 12. One example usable material is a pressed paperboard tray constructed of solid bleached sulfate of about 268-329 lbs/3000 sq. ft. For example, a paperboard tray of a solid bleached sulfate construction and being able to sustain about 295-305 lbs/3000 sq. ft. is usable.

The tray 12 includes a holding surface 20. The flat holding surface has a substantially flat cooking side 22 and an opposite oven-engaging side 24. By the term “substantially flat”, it is meant to distinguish bowl-shaped or curved shaped cooking sides, but does allow for small changes (unflat) shapes in the surfaces for embossments or embossments or general material irregularities. The cooking side 22 functions to interact with the crust 16 of the pizza 14 and provide a cooking surface for the pizza 14. In implementation, one usable material for the cooking side 22 is polybutylene terephthalate (PBT) polyester. The cooking side 22 is preferably flat without curves, arcs, or bends, but as mentioned above, does allow for embossments, small minor unflat surface changes, and general material irregularities. It has been found that a flat (including substantially flat) cooking side 22 results in desirable properties for the baked crust 16. The oven-engaging side 24 is also preferably substantially flat in some embodiments.

In the embodiment shown in FIGS. 2-4, the tray 12 further includes a side panel 26. The side panel 26 extends vertically from the holding surface 20 to form a perimeter side panel or border 27. The tray 12 may have a variety of shapes. The tray 12 can be rectangular, square, irregular, round, etc. In the particular embodiment illustrated in FIGS. 1-4, the tray 12 is round or circular. The tray will be a size that is a size small enough to fit within a normal, consumer-size oven. For example, usable sizes include an overall length of 4-20 inches. If round, this length would be a diameter of 4-20 inches. A useful perimeter side panel 26 will extend 0.25-1.0 inch from the holding surface 20. In preferred implementations, the side panel 26 will have a taper such that it will be angled away from the cooking surface 22 at about 13-23 degrees off of a vertical line, for example, about 17-19 degrees off of a vertical line. A useful overall dimension, such as a diameter, of the tray 12 would be 5-18 inches, with a perimeter side panel 26 extending 0.25-0.75 inch. The tray 12 can also have a flange 30 extending from the side panel 26. The flange 30 can have a length of 0.12-0.25 inch, for example, 0.18-0.19 inch. When there is a side panel 26, such as in the example shown in the drawings, the tray 12 will have a depth measured from the top of the side panel 26 (corresponding to the flange 30) to the top of the cooking side 22 of about 0.4-0.6 inch, for example, about 0.5 inch.

Turning again to FIG. 1 and FIG. 5, the pizza 14 includes, in the embodiment shown, a cut arrangement 40 extending through a thickness of the crust 16. The cut arrangement 40 includes a cut line 42 having uncut portions 44 of the crust 16 along the cut line 42. The cut arrangement 40 can be in a variety of implementations. For example, the cut arrangement 40 can cut the pizza 14 into various geometric patterns or shapes. The cut arrangement 40 can be at least one cut line, including a single cut line 42 or can include, as shown in the embodiment of FIG. 1, a plurality of cut lines 46. Each of the cut lines 46 extends through the thickness of the crust 16 from a top 48 of the pizza 14 all the way through to a bottom 50 of the pizza 14. In the embodiment shown in FIG. 1, the cut lines 46 divide the pizza 14 into individual serving pieces 52.

Still in reference to FIG. 1, the cut lines 46 include uncut portions 44 along the cut lines 46 such that no individual serving piece 52 is disconnected from a remaining portion of the pizza 14. The cut arrangement 40 is in place, such that, in the embodiment of FIG. 1, the entire frozen pizza 14 can be moved around, transferred, and placed in the tray 12 in a single piece without the individual pieces 52 becoming separated from the remaining portion of the frozen pizza 14. This is convenient for manufacturing purposes, for example.

Preferably, the cut lines 46 are formed by a water-jet process, so that the cut lines 46 are water-jet formed cut lines. One usable water-jet formed cut line will be made by using a water-jet that uses a 0.009 inch orifice. It should be understood that while using a water-jet cutter to result in water-jet formed cut lines is one usable method, other methods can be used to achieve cut lines, including ultrasonics to result in ultrasonic formed cut lines, or knives or blades to result in blade formed cut lines

In the embodiment of FIG. 1, the frozen pizza 14 is circular, and the cut lines 46 form individual serving pieces 52 cut into at least six sectors 56 of the pizza 14. In the particular embodiment shown, the pizza 14 is cut into eight sectors 56. In one embodiment, the pizza 14 includes a single cut line 46, cutting the pizza 14 into two sectors 56. As such, the cut line 46 divides the pizza 14 into at least two sectors 56, and it should be understood that the cut line 46 can divide the pizza 14 into more than eight sectors 56, such as up to 30 sectors.

Between adjacent ones of the sectors 56 are the uncut portions 44. While sectors 56 are illustrated, and as mentioned above, it should be understood that the pieces 52 can be cut into a variety of patterns including rectangular, square, irregular, triangle, etc. Each of the uncut portions 44 has a length that is sufficiently long to hold the individual pieces 52 together with a remaining portion of the pizza, but small enough to allow for it to be easily separated without the use of tools, from a remaining portion of the pizza after baking by the consumer. For example, it is convenient if each of the uncut portions has a length no greater than 1 inch. It is convenient if each of the uncut portions has a length of ⅛thth inch.

In the embodiment shown, there is a single uncut portion 44 between each adjacent sector 56. In other implementations, there can be more uncut portions 44 between adjacent individual pieces 52. For example, a perforated cut line could be used in which a plurality of cut portions alternately trade off with uncut portions in series.

Certain dough formulations have been found usable with the tray 12 to result in a crust that good performance with the tray 12. For example, a dough formulation having the following has been found useful, with percentages given being percentage of weight: flour, spring hard 55-65%; water, 25-30%; salt, granulated 1-3%; sugar, granulated, 1-3%; yeast, cream, 3-8%; shortening, palm flakes, 1-4%; dough conditioner, 1-2%. Further ingredients can include bread crumbs and garlic butter oil. For pizzas having an 11 inch crust, the weight of the dough plus the bread crumbs and garlic butter oil will be about 11-12 ounces. For a pizza having a crust of about 13 inches, the weight of the dough plus the bread crumbs and garlic butter oil will be about 16-17 ounces.

One useful dough formulation includes the following, with percentage given being percent of weight: flour, spring hard 59-60%; water, 28-29%; salt, granulated 1-2%; sugar, granulated, 1-2%; yeast, cream, 5-6%; shortening, palm flakes, 2-3%; dough conditioner, 1-2%. For an 11 inch diameter crust, about 0.4-0.6 oz. bread crumbs, and 0.15-0.25 oz. garlic butter oil. For a 13 inch diameter crust, about 0.65-0.75 oz. bread crumbs and about 0.3 oz. garlic butter oil.

A method of making a combination frozen pizza and bakeable tray is provided. The method includes providing an uncooked and unfrozen pizza. The pizza would include a crust with toppings. Next, a cutter (such as a water jet, or ultrasonics, or a blade) slices the pizza to form cut lines 46 into individual pieces 52 and leave uncut portions 44 along the cut line 46 such that no individual serving piece 52 is disconnected from a remaining portion of the pizza. Next, the sliced pizza is placed onto the bakeable tray 12, such that the bottom 50 is oriented against the flat cooking surface 22 on the bakeable tray 12 to form a sliced pizza and tray arrangement. The step of placing the sliced pizza onto the tray is convenient since the uncut portions 44 hold the entire pizza together, so that no individual pieces are separated from a remaining portion of the pizza. Next, the sliced pizza and tray arrangement is frozen. The frozen sliced pizza and tray arrangement can be packaged into packaging materials for sales to a consumer before or after freezing.

The step of slicing includes, if the pizza is circular, slicing the pizza into at least two sectors and leaving uncut portions 44 along the cut lines 46, with each uncut portion having a length no greater than one inch. The method of slicing can also include slicing the pizza into a variety of other shaped individual pieces or into a variety of other shapes.

A method of making a pizza includes putting the frozen pizza and tray combination 10 into an oven. Next, the frozen pizza and tray combination 10 is baked for a suitable amount of time to result in a cooked pizza on the tray. For example, the frozen pizza can be baked at an oven of 350-500 degrees for 10-20 minutes. Next, the tray holding the cooked pizza is removed from the oven. Next, the cooked pizza is divided into individual serving pieces by manually, and without the use of a cutter, breaking the uncut portions 44 of the crust 16. After the pizza has been consumed or otherwise disposed of or stored for later consumption, the tray 12 is disposed of, such as in the garbage or recycled. The tray 12 is made of a material that can be incinerated as well. The tray 12 is not reused.

The step of dividing the pizza includes pulling by hand an individual serving piece 52 away from a remaining portion of the pizza 14 and breaking at least one uncut portion 44. The uncut portion 44 will have a length of not greater than one inch. It should be understood that the use of a cutter is not needed. If, for some reason, the consumer would like to use a pizza cutter, it is certainly possible for the consumer to use a cutting device on the uncut portions 44.

Experimental Results

The crust 16 has been formulated and selected to perform with the paperboard baking tray 12 to result in surprisingly good properties. Just any pizza crust will not give high quality, desirable properties.

Research was conducted among past 6 month super-premium frozen pizza users. Respondents also must have been past 6 month purchasers of delivery pizza in the “Delivered Pizza” cells. Specific respondent qualifications included:

    • Age 21-54
    • Primary/Shared Grocery Shopper
    • HH Income of $50,000 or more
    • Past 6-month purchaser of super-premium frozen pizza (for example, Freschetta, DiGiorno, CPK, Wolfgang Puck)
    • In the “Delivered Pizza” cells, past 6-month purchasers of delivery pizza (for example, Pizza Hut)
    • Open to Pepperoni variety
    • No food allergies
