## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a Continuation-in-Part of PCT International Application No. PCT/IL2010/000805, which has an international filing date of Oct. 3, 2010, and which claims priority from Israel Patent Application No. 202628, filed Dec. 9, 2009, all of which disclosures are hereby incorporated by reference.


FIELD OF THE INVENTION
The present invention relates to the field of packing and serving pizza pies. More specifically, the present invention relates to a double pizza pack that can be produced from a single sheet by a single punch.
BACKGROUND OF THE INVENTION
Pizza is very popular fast food in the west. The form of provision of pizza plays a major role in its popularity. The facts that pizza pies are baked by experts in an oven designed especially for this purpose, and usually delivered within 30 minutes from its order, have contributed to its popularity.
Delivering pizza pies from a retail shop to a client's house is usually carried out in a pack, which retains the form and warmth of the ordered pizza pie. As such, a pizza pack has to be designed such that its size provides some space between the pizza and the pack, in order to prevent contact between the top of the pizza and the cover of the pack. In addition, the pack must be made of an isolating material. Also, the material the pack should have certain stiffness, in order to keep the space between the pizza and its pack.
Pizza packs are made of flat stiff material, such as cardboard, which comprises scissions or other means that allow folding the cardboard to a pack. Pizza retailers keep the cardboards in their flat form until forming a pack from it, since this way the storage takes less space. The design of pizza packs must provide easy, fast shaping of a pack from its flat cardboard, in order to decrease the time of the process.
A substantial percentage of pizza orders are for a couple of pizza pies. In this case, it is common to deliver each pizza in an individual pack.
One of the objects of any cardboard product is to produce the product from a single sheet, by a single punch, thereby reducing the manufacturing effort.
It is an object of the present invention to provide a pack for delivery of two or more pizza pies.
Other objects and advantages of the invention will become apparent as the description proceeds.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.
FIGS. 1 to 6 schematically illustrate a double pizza pack, according to one embodiment of the invention. The pizza pack is marked in these figures as 1.
The pizza pack illustrated in these figures is characterized by the fact that the entire pack is made from a single sheet, punched by a single punching operation. As this form spares the need of attaching two or more separate sheets each other, as in the other embodiments of the invention, this form is more efficient for the staff that forms the double pizza pack from the sheet.
As illustrated, the single sheet of the double pizza pack 1 comprises a lid 2, a bottom 28 of the lower pizza compartment, and a bottom 26 of the upper pizza compartment, connected each other by straps: Lid 2 is connected to bottom 28 by strap 52, and bottom 28 is connected to bottom 26 by strap 54. The straps are a part of the same sheet that lid 2, bottom 28 and bottom 26 are made of. These straps are a part of the walls of the pizza compartments.
The characteristics that allow manufacturing a double pizza pack from a single sheet is the fact that the height of strap 52 is about twice as much as the height of strap 54. In addition, walls 10 of the lower pizza compartment have the same height as strap 54, and walls 60 of the upper pizza compartment have the same height as strap 52. Thus, the bottom of the upper pizza compartment is disposed in the middle of the height of pizza pack 1.
In another words, in the embodiment illustrated in these figures, pizza pack 1 is made of a single sheet comprising folding lines forming: a base plate 28, for use as the bottom of a lower pizza compartment; a lid plate 2, connected to the base plate 28 by a first strap 52; a division plate 26, connected to the base plate 28 by a second strap 54, for dividing the space between the lid 2 and the bottom 28 into two compartments; wherein the height of the first strap 52 being twice as the height of the second strap 54, thereby allowing forming the pack from a single sheet, by a single punch.
FIG. 1 illustrates pizza pack 1 as a cut from a single sheet. In this form, all the parts of the pizza pack are seen.
In FIG. 2 illustrates a stage in folding the flat sheet into a pizza pack.
Firstly, straps 52 and 54 are folded. Then, the lower compartment is assembled as follows:
Firstly, tabs 72 of bottom 28 are folded. Then, walls 10 are folded along folding line 47, which is disposed in about the half of its height. Each tab 72 is disposed between the corresponding folded walls 10. Wall 10 is fixed using tab 46 and its corresponding slot 48 (better seen in the magnified illustration in FIG. 3). This form provides a massive structure to the lower pizza compartment.
Lid 2 is formed in the same manner. Firstly, tabs 70 of lid 2 are folded. Then, walls 64 are folded along folding line 57, which is disposed in about the half of its height. Each tab 70 is disposed between the corresponding folded walls 64. Wall 64 is fixed using tab 56 and its corresponding slot 58. This form provides a massive structure to the lower pizza compartment.
Then, walls 12 that support bottom 26 of the upper pizza pack are folded, as illustrated in this figure.
At this stage, the double pizza pack is ready for use.
In FIG. 3, a pizza pie 22 is placed into the lower compartment. Then, element 26 is closed as a lid. Element 26 is used also as the bottom of the upper pizza compartment.
In FIG. 4, the lower compartment is closed, and the upper pizza pied 22′ is placed on the bottom of the upper compartment 26.
Tab 50, which is a part of element 26, is folded in 90 degrees. In this situation, it is used as a support for lid 2, to prevent from lid 2 to touch upper pizza pie 22′. After the upper pizza pack 22′ is placed, lid 22 is closed.
FIG. 5 illustrates the closed pizza pack.
Opening the closed pizza pack can be carried out by holding tab 68 with one hand, and pulling lid 2 upside. Tab 68 is a part of element 28, which is the bottom of the closed pizza pack.
In FIG. 6, lid 2 the upper pizza pie slides into the upside-down lid 2, exposing element 26, thereby allowing opening the lower compartment. Furthermore, lid 2 can be separated from the rest of the pizza pack, resulting with two separated open compartments.
FIG. 7 schematically illustrates a pizza pack, according to a further embodiment of the invention.
According to this embodiment of the invention, lid 2 is perforated by perforation 6, in a shape of slices of a pizza pie 8. Each slice 8 may comprise a tab 4. By lifting and pulling tab 4, the corresponding slice is separated from the lid. Each slice 8 can be used as a pizza slice server.
U.S. Pat. No. 6,851,601 discloses a dual pizza pie container system is provided, which includes a solid rectangular enclosure and a pizza support platform within the enclosure. The pizza support platform includes four foldable equilateral flaps which, when folded to generally right angles relative to a central base, define an octahedron having four long edges defining a virtual square and four alternating diagonal edges at corners of the support platform when folded. One of the equilateral flaps is provided with an aperture therein which effects registration with the an aperture of the fourth sidewall of the top cover of the enclosure in which widths of the equilateral sidewalls of the platform define about one-half of the height of the sidewalls of the enclosure. Thereby, upper and lower interior solid horizontal compartments, one above and one below the platform, are defined when the support platform is positioned within the enclosure and the enclosure is closed.
U.S. Pat. No. 6,915,949 discloses a rectangular box for transporting multiple pizza pies in a stacked formation formed by a single cardboard blank having scoring and cut-outs for assembling into a multiple pizza box. The box has a bottom wall, four side walls and a lid hinged to one of the side walls. When assembled the box has a pair of corner shelf supports and a removable shelf for positioning a second pizza pie. The shelf supports also provide a stop for the lid of the box to prevent crushing the contents. Both the rectangular box and a removable shelf can be stored flat when not in use.
