Abstract:
A carry handle ( 33 ) for carrying a pizza box or cake box or other boxed food product is made of inexpensive disposable paper or cardboard and comprises a pair of strap portions which generally are parallel to each other and in a side-by-side relationship and are joined to each other by a fold line ( 17 ). The strap portions can be twisted about the fold line ( 17 ) into a cross like configuration. A pizza box can then be placed on the cross like configuration. The strap portions are longer than the width of the pizza box and can therefore be lifted up and over the pizza box and connected together to form a reliable carry handle.

CROSS REFERENCE TO RELATED APPLICATION 
     This application takes priority from and claims the benefit of Australian Patent Application No. 2015203850 filed Jul. 9, 2015, the disclosure of which is hereby incorporated by reference. 
     TECHNICAL FIELD 
     The present invention is directed to a carrying handle and especially to an inexpensive single use strap-like handle for carrying boxed food items such as pizzas and cakes. 
     BACKGROUND 
     Any references to methods, apparatus or documents of the prior art are not to be taken as constituting any evidence or admission that they formed, or form part of the common general knowledge. 
     Carrying purchased, take away, boxed food items such as pizzas can present problems. The pizza box is quite large in length and width but quite small in height. The boxes are manufactured as inexpensively as possible to keep the cost of the boxed pizza as low as possible. Thus it is not uncommon for the pizza containing box to sag which can cause the pizza to fall out of the box, or the box be dropped. A hot pizza can cause the bottom of the box to become too hot to hold. Hot fat or cheese can ooze from the box and onto a person&#39;s hands causing burns. 
     The problem is exacerbated when multiple boxes need to be carried from the pizza outlet. The boxes are typically stacked on top of each other and held in a manner that is likely to cause burns to hands, wrists and arms when carried. 
     It is known to manufacture a pizza box having a built in handle on the top of the box. This does not overcome sagging of the bottom of the box. To do so, the box is made of thicker stronger material which adds to the cost of the box and therefore the pizza. The arrangement does not allow for multiple boxes to be stacked on top of each other while still being carried. 
     It is known to provide a paper or similar band to hold bundled items together. An example is the paper strap holding face towels in a bundle as would be found in the bathrooms of some hotels. Such bands are not designed to hold heavier objects and are not designed to enable the objects to be carried by the band. Instead any carrying still requires the towels or other objects to be held as the band does nothing more than to stop the towels from falling off each other. These bands/straps are more commonly known as an “organizing strap” as opposed to a carrying handle. 
     It is known to provide a strap like handle which is attached to opposite edges of a pizza box. This handle provides no support for the box bottom which can easily sag. The box cannot be opened to inspect the pizza once the handle is attached, so the handle needs to be attached after the purchaser has handled the hot pizza box to inspect the contents prior to purchase. US patent 2011/0049922 describes such a handle. 
     Another carry handle comprises handle portions that need to be firmly gripped essentially to hold the handle to the box. This may prove too difficult for children and the elderly. The handle is a flexible cloth like arrangement which is not easy to store in a dispenser as it would more likely tangle with other handles in the dispenser. The carry handle is therefore typically owned by the pizza purchaser and is reusable and washable. U.S. Pat. No. 8,579,344 describes such a carry handle. 
     U.S. Pat. No. 7,841,635 similarly describes an expensive quick release strap assembly for bags and packages. The assembly has metal clips and strong webbing straps and would be totally unsuited as a disposable pizza box carry handle. 
     DE 20308891U describes a large pizza box carrier which has a large square base and extending straps. Such a device is large and unsuited for compact initial storage (for instance on a counter top at the pizza outlet). The carrier has no easy to hold looped handle portion. The size of the carrier unnecessarily adds to the cost of the pizza. A much smaller reliable mass producible and inexpensive carrier would be much more suited. 
     Other types of handles for carrying fragile objects comprise multiple separate bands or straps which must be placed about the object in a particular manner. Clearly, there is a disadvantage in having a carry handle of separate parts as these need to be stored separately and then assembled about the object. If the object is a hot pizza box, the multi-step assembly can expose a person to burns. There would be an advantage to provide a carry handle made of a single piece. U.S. Pat. No. 4,784,265 describes a multi-part carry handle. 
     Another disadvantage with carrying boxed food items such as pizzas, cakes and the like is that the purchase often includes other items such as drinks, garlic bread and the like. Carrying these with the boxed food item can be difficult and can cause items to be dropped. 
     Another disadvantage is that the purchaser of such boxed food items is usually already carrying personal items such as car/house keys, mobile phone etc. These items can be dropped and damaged when attempting to carry boxes of pizzas, drinks, deserts, cakes and the like. 
     The pizza outlet may also be liable if a customer is scalded by hot fat or liquid oozing from the box. 
     Of course, the purchaser can be highly organized and arrive with a bag or carry box to hold the various items, but in practice this does not happen very often. 
     Thus, there seems to be currently no product on the market which allows consumers of pizzas or cakes to carrying the boxes in a safe manner and preferably in one hand to enable the other hand to hold car keys, a mobile phone, a child&#39;s hand and the like. 
     It is an object of the present invention to provide a carry handle that may overcome at least one of the above disadvantages or provide a useful or commercial choice in the marketplace. 
     SUMMARY OF THE INVENTION 
     According to a first aspect of the present invention there is provided a carry handle for a boxed food item, the handle comprising an elongate strap having: 
     a first strap portion; 
     a second strap portion; 
     a first fold line attaching the strap portions together the first fold line being entirely on one of the strap portions and extending from one longitudinal edge of the strap portion and diagonally to a point spaced inwardly from the other longitudinal edge of the strap portion; 
     wherein the strap portions are foldable about the first fold line between a non-use position where the strap portions are generally parallel to each other and a carrying position where the strap portions are angled to each other. 
     A non-limiting embodiment of the carry handle in the non-use position is illustrated in  FIGS. 1 and 5 , and in the carrying position is illustrated in  FIGS. 6 and 7  at least. In the non-limiting embodiment, the first strap portion has reference numerals  10  and  11 , the second strap portion has reference numerals  12  and  13 , and the first fold line has reference numeral  17 . The carry handle can have additional fold and cut lines that will be described below. 
     The carry handle may comprise a disposable or single use strap. 
     The strap may be manufactured from environmentally friendly paper or cardboard. The paper may be treated to provide a degree of strength when wet. The paper may be may be waxed or otherwise coated. The paper may contain fillers. Similarly, the cardboard may be treated, coated or contain fillers. The strap may be made from other materials; however it is preferred that any such material is inexpensive, reliable, “food safe” and is environmentally friendly. Certain degradable plastics may be suited. Some laminated materials may be suitable. A woven or non-woven stiff fabric may be suitable. 
     The strap may be pre-cut from a stencil. 
     The strap can be easily assembled and placed around small, medium or large sized boxes such as pizza or cake to enable the consumer to carry the boxes using one hand. The strap can allow consumers to carry more than one box at a time as well as additional items such as bottles of soft drink with one hand. 
     In addition, use of the strap prevents the consumer from carrying boxes containing hot items in their hands. 
     The length of the first strap portion and a second strap portion may vary depending on the size and shape of the boxed food item to be carried. It is envisaged that the length of the first strap portion and a second strap portion will be between 60-100 cm. It is also preferred that the first portion and the second strap portion are of the same length or approximately the same length. 
     The width of each strap portion may vary depending on the type of material from which the carry handle is made. For instance, a wider strap portion may be able to securely hold a larger weight using cheaper materials. It is envisaged that the strap portion will typically have a width of between 2-5 cm. 
     For ease of manufacture, it is envisaged that each strap portion will be substantially rectangular when viewed in plan. However, there may be circumstances where there is an advantage in providing different shapes. For instance, each strap portion may include some form of edge profile to assist in connecting the edges together to form the carry handle. 
     The, or each, strap portion may be reinforced if desired. For instance, the strap portion may include reinforcing filaments or some form of reinforcing grid or mat type arrangement. It is also envisaged that the, or each, strap portion may include certain areas or zones that are stronger or thicker or reinforced. 
     It is envisaged that the carry handle will be made of the same material. However, there may be circumstances where part of the carry handle (for instance part or all of one or both strap portions) are made of dissimilar materials to provide strength and durability. For instance, part of the strap portion may be made of water resistant material such that the carry handle does not fail should part of the carry handle to become damp (for instance liquid oozing from the food product or condensation from the drink bottle). 
     The strap member may contain advertising material printed or otherwise applied to the strap member. 
     The first strap portion and the second strap portion are connected by the first fold line. However, it is preferred that the portions are further initially attached together by a frangible portion or portions. These may comprise serrations, tear lines, tear off tabs, lines of weakness, or other means to enable the portions to be initially held together by more than the first fold line, but relatively easily separated (bar the fold line) to enable the portions to be twisted and folded to the “use” position. The initial additional temporary attachment can make the carry handle more sturdy and robust when in the initial non-use position, so that multiple such handles can be stacked together with little likelihood of separate handles becoming entangled together. 
     The point is suitably approximately midway across the strap portion. The diagonal angle is suitably an obtuse angle of about 135°. The fold line may be an imaginary line. Alternatively, the fold line may comprise a visible line to facilitate correct folding about the fold line. The fold line may also comprise a small groove or other profile to facilitate folding about the fold line. 
     The fold line is preferably located about midway between the opposed end edges of the strap member. An advantage of this location is that when the handle is in the “use” position (see, for instance  FIG. 7 ), the handle is “balanced” as the strap portions intersect each other at about the midway portion. If the fold line was towards one end edge, the strap portions will intersect away from the midway point which may unbalance the carry handle. However, for small pizza boxes, the precise location of the fold handle may not need to be exact. 
     The strap portions are generally parallel to each other in the initial non-use portion. The portions are also suitably in a side by side relationship as illustrated at least in  FIGS. 1 and 5 . This arrangement allows carry handles to be more easily stacked together in a box or other dispenser prior to use. 
     The strap portions are suitably sufficiently stiff to be more easily stacked together in a box or other dispenser prior to use and easily removed from the box. 
     In the carrying position, the strap portions are suitably folded or moved to a position substantially at right angles to each other, such that, in plan, the straps resemble a cross. 
     The first fold line suitably communicates with a first cut line to facilitate the folding action. The cut line suitably extends from adjacent a longitudinal edge of the strap portion and to the end of the fold line to form a V configuration when viewed in plan. 
     One of the strap portions suitably comprises an interconnection means to enable end regions of the strap member to be interconnected. The interconnection means may comprise open ended cutouts. Each end region of the strap member may have one or more of such cutouts to connect the ends together.  FIG. 5  and  FIG. 7  at least illustrate non-limiting cutouts  21 ,  22 . 
     The other strap portion suitable comprises an opening to enable the first strap portion to pass through the opening. A pair of openings may be provided. The openings may comprise slots which are suitably aligned when ends of the strap are overlapped.  FIG. 5  and  FIG. 7  at least illustrate non-limiting slots  19 ,  20 . 
     One of the strap portions may comprise additional fold lines to facilitate folding of the strap portion about an upper edge of a food box being carried.  FIG. 8  and  FIG. 11  at least illustrate non-limiting examples of such additional fold lines  30 ,  31 .

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     Referring initially to  FIG. 1  and  FIG. 5 , there is illustrated a carry handle  33  for a boxed food item  24 , the handle comprising an elongate strap having: 
     a first strap portion  10 / 11 ; 
     a second strap portion  12 / 13 ; 
     a first fold line  17  attaching the strap portions together; 
     wherein the strap portions are foldable about the first fold line between a non-use position where the strap portions are generally parallel to each other and a carrying position where the strap portions are angled to each other. 
     The carry handle as illustrated in  FIGS. 5-12  more accurately illustrates the commercial product, while the carry handle as illustrated in  FIGS. 1-4  is schematic and is used to better illustrate the folding steps. 
     Referring to  FIG. 1 , the carry handle  33  is made of a disposable relatively stiff paper or cardboard. Specifically, the carry handle  33  comprises an elongate strap like member which has a first strap portion and a second strap portion which are connected together. To better illustrate and understand the folding sequence of the carry handle from the flat non-use position of  FIG. 1  (and  FIG. 5 ) to the use position illustrated at least in  FIG. 7 , the various parts of the strap portions are given different reference numerals. Therefore, and referring at least to  FIG. 1 , the first strap portion is given reference numeral  10  for one half of the first strap portion, reference numeral  11  for the other half of the first strap portion. The other side (face) of the first strap is given reference numerals  10 A and  11 A as illustrated at least in  FIG. 2 , and part  10 A is directly behind  10  and  11 A is behind  11 . Similarly, the second strap portion has a front face with reference numeral  12  on one half of the front face and reference numeral  13  on the other half of the front face, and also has reference numerals  12 A and  13 A on the other face of the strap. 
       FIG. 1  also illustrates the first fold line  17  and a cut line  16 . 
     Strap portions  10 / 11  and  12 / 13  are connected together at least by fold line  17 . However, initially, the portions may also be temporally connected along cut lines  14  and  15 , for instance by frangible portions, so that the initial stiff planar configuration of  FIG. 1  is maintained and the strap portions do not begin to sag relative to each other. 
     The carry handle  33  can be mass produced from inexpensive paper or cardboard and used by the pizza or food outlet. 
     When required, a carry handle  33  can be removed from a box or dispenser. Next, any temporary connections between the strap portions can be broken. This can be done by folding strap portion  10 / 11  onto a L shape relative to strap portion  12 / 13 . 
     Next, a person holds “second” strap portion  12 / 13  and twists “first” strap portion  10 / 11  about fold line  17  by about 90° such that portion  11  rotates above the plane and portion  10  rotates below the plane. Then the “first” strap portion is folded against the second strap portion as illustrated in  FIG. 2 . In this figure the rear face of the first strap portion is uppermost and therefore has reference numerals  10 A and  11 A. 
     Finally, and as illustrated from  FIG. 2  to  FIG. 3 , the first strap portion is folder by 180° about fold line  18  to again have the front face visible  10 / 11 . The first strap portion also is positioned midway along the (lower) second strap member. 
     Although the above describes and illustrates a separate multistep process, in most cases the twisting about fold line  17  and folding about fold line  18  will happen simultaneously in a single smooth sequence. 
       FIG. 4  illustrates the underneath view of  FIG. 3 . 
       FIGS. 5 and 6  illustrate the same process as described above. 
       FIGS. 5 and 6  illustrate further features of the carry handle. Specifically,  FIGS. 5 and 6  illustrate that one of the strap portions (for instance  10 - 11 ) containing slots  19 ,  20  adjacent each longitudinal end of the strap portion, and the other of the strap portions (for instance  12 - 13 ) contain cutouts  21 ,  22 . These slots  19 ,  20  and cutouts  21 ,  22  assist in holding the various strap portions into the final shape of the carry handle and this will be described hereinafter. 
     Referring now to  FIG. 7 , the strap portions as illustrated in  FIG. 6  (being substantially at right angles to each other) can now be further folded to the arrangement illustrated in  FIG. 7 . Specifically, strap portion  10 - 11  is folded upwardly and looped together such that the slots  19 ,  20  overlie each other and the slots are aligned. It is envisaged that some form of press stick adhesive may be provided to assist in holding strap portion in the loop configuration illustrated in  FIG. 7 . The adhesive may be protected by a peel off cover layer. 
     Once the slots  19 ,  20  are aligned, the other strap portion  12 - 13  can also be looped upward with each opposed end being pressed together and pushed through the aligned slots  19 ,  20 . Once this occurs, the pushed through end parts of strap portion  12 - 13  can be connected together by engaging cutout  21  with cutout  22 . 
     The carry handle is now in the use position and can hold a pizza box  24  (see  FIG. 8 ). The person can then grip the “handle” portion  27  of the carry handle in a convenient manner especially because of the inter-engagement of the end of strap portion  12 - 13  via a connection of the cutouts  21 ,  22 . 
     The pizza box  24  is firmly supported on its base by both straps being at right angles to each other. Furthermore, the top of the box can still be opened to inspect the pizza. 
     The strap can be quite easily removed typically by tearing the strap away from the box, or with slightly more patience, by pushing the “handle” portion  27  back through the aligned openings  19 ,  20 . 
     Strap portion  12 ,  13  can be provided with additional fold lines  30 ,  31  (see for instance  FIG. 7 ,  FIG. 8  and  FIG. 11 ). The fold lines can be positioned to approximate the height of a pizza box to enable better gripping of the sides of the pizza box. Fold line  31  is a fold line should two pizza boxes (see  FIG. 11 ) need to be held by the carry handle. 
     Another advantage of the carry handle is illustrated in  FIG. 9  and  FIG. 12 . Drink bottles  25  can be laid on top of pizza box  24  and can be at least partially supported by the carry handle. The strap portions of the carry handle will at least prevent the drink bottles rolling off each side edge of the pizza box. 
     Other additional purchases (such as garlic bread) can also be placed on the pizza box and the entire purchase can be carried with one hand in a safe manner with little or no likelihood of contact with the hot pizza box or inadvertent dropping of the pizza box or drink bottles. 
     This can reduce possible liability against the pizza outlets. 
     The other hand of the person carrying the pizza box/drink bottles etc. is free and can hold car keys, a mobile phone, a child hand and the like. 
     The inexpensive nature of the carry handle will make it acceptable to pizza outlets. 
     Advertising can be printed or otherwise applied to the various parts of the carry handle. 
     The strap is assembled by the vendor based on the pre-cut stencil and folded along the embedded fold lines and placed around the boxes to enable to customer to carry the boxes securely in one hand. The four sides of the strap encase the box and are secured by interlocking the looped handle at the top for ease of transporting boxes with one hand. 
     It is intended that vendors would have the option of placing advertising or printing menus or specials on the strap if desired. 
     USE FOR THE INVENTION 
     The above description and illustrations demonstrate how the invention may be used as a disposable inexpensive carry handle for hot pizza boxes, additional drink containers, and also for other box food items that may be difficult to carry such as large (and possibly fragile) cakes and the like.
