Description
BLANK FOR A PIZZA BOX
Technical Field
The present invention relates to a blank for a pizza box and a method of assembling a pizza box.
Background
Cardboard boxes have traditionally been used as packaging for freshly cooked pizzas. The box seeks to provide a rigid structure to protect the pizza as it is being delivered from the shop to the customer. The box also seeks to keep the pizza ventilated and/or insulated.
For ease of storage, the pizza boxes are typically supplied to pizza shops in flat blank form to be assembled on site. A busy pizza shop can produce fifty to one hundred pizzas per hour during peak times. As such, it is advantageous to have a pizza box that facilitates quick assembly.
A great number of pizza boxes have been developed over time, each with different structural and thermal qualities. Various methods of assembly have also been developed with a view to easing the burden on the pizza shop. For example, Dominos™ created a pizza box, including:
(a) a planar base section hingedly coupled to a corresponding planar lid section by a rear panel arranged therebetween;
(b) a front wall panel hingedly coupled to a front end of the base section, the front wall panel being arrangable to extend normally to the base section;
(c) first and second side wall panels hingeldy coupled to respective opposed sides of the base section, the side wall panels being arrangable to extend normally to the base section;
(d) first and second front comer rollovers respectively coupled between:
(a) the front wall panel;
(b) one of the side wall panels; and
(c) a stepped in section of the base section; and
(e) reverse lock tabs.
During assembly, the front panel is lifted whilst folding over the front comer rollovers. To enable the front comer rollovers to lock in place, the reverse lock tabs are folded backwards and are locked in place. The lid is then closed as per traditional pizza box.
In practice, the process of folding the reverse lock tabs can be hit and miss as they are relatively small and can take a few seconds to activate the locking mechanism. As such, the assembly time for each pizza box can be significant if the skill of the person doing the assembly is poor.
Further, there is significant memory associated with the front panel crease causing the entire panel to want to spring open. This resilience can put a strain on the small lock tabs which can lead to box failure.
Pizza boxes historically bear the trad mark indicia of the relevant pizza shops. This has traditionally involved printing the indicia onto the surface of the box. Simply printing trade mark indicia onto a pizza box may not be sufficient to adequately make a pizza box stand out from the pack.
It is also advantageous to have a pizza box that bears the indicia of the pizza shop. It may not be optimal to simply print the pizza shops trade marks on the box.
It is generally desirable to overcome or ameliorate one or more of the above described difficulties, or to at least provide a useful alternative.
Summary
In accordance with the invention, there is provided a blank for a cardboard pizza box, including:
(a) a planar base section hingedly coupled to a corresponding planar lid section by a rear panel arranged therebetween;
(b) a front rollover hingedly coupled to a front end of the base section, the front rollover being arrangable to extend normally to the base section;
(c) first and second side wall panels hingeldy coupled to respective opposed sides of the base section, the side wall panels being arrangable to extend normally to the base section;
(d) locking tabs hingedly coupled to respective ends of the first and second side wall panels, the locking tabs being arrangable so that the front rollover folds over the locking tabs when the side wall panels are normal to the base section;
(e) first and second rear comer rollovers, each comprising:
(i) a right angled triangular panel with its hypotenuse hingedly coupled to a stepped in rear comer section of the base section;
(ii) a rear panel tab hingedly coupled between an end of the rear panel and a rear side of the triangular panel; and
(iii) a side panel tab hingedly coupled between an end of one of said side panels and another side of the triangular panel.
Preferably, the blank can be assembled into a pizza box by performing the steps of:
(a) folding the side walls panels so that they are normal to the base section;
(b) folding the locking tabs inwardly so that they are normal to respective side wall panels;
(c) folding the front rollover over the locking tabs so that it is normal to the base section;
(d) folding each of the first and second rear comer rollovers in the following manner:
(i) folding the triangular panel inwardly so that it overlies the base section; and
(ii) folding the side panel tab so that it is normal to the base section and extends diagonally, along the hypotenuse of the triangular panel, from the end of one of said side panels towards the rear panel; and
(iii) folding the rear panel tab so that it is normal to the base section and extends transverse to the side panel tab.
Preferably, the side panel tab is hingedly coupled to the triangular panel in two spaced apart locations, each proximal to a respective vertex of trianglular panel. The triangular panel is hingedly coupled to the stepped in comer of the base section in two spaced apart locations, each proximal to a respective vertex of trianglular panel.
Preferably, a non-normal vertex of the triangular panel proximal to the side panel is rounded. The rounded vertex of the triangular panel is a cut line that assists with assembly of the rear comer rollovers. Another non-normal vertex of the triangular panel is blunt. The blunt vertex is a cut line that assists with assembly of the rear comer rollovers.
Preferably, the blank includes debossed trade mark indicia.
In accordance with the invention, there is also provided a method of assembling a pizza box from the above described blank, including the steps of:
(a) folding the side walls panels so that they are normal to the base section;
(b) folding the locking tabs inwardly so that they are normal to respective side wall panels;
(c) folding the front rollover over the locking tabs so that it is normal to the base section;
(d) folding the rear panel so that is normal to the base section; and
(e) folding each of the first and second rear comer rollovers in the following manner:
(i) folding the triangular panel inwardly so that it overlies the base section; and
(ii) folding the side panel tab so that it is normal to the base section 14 and extends diagonally, along the hypotenuse of the triangular panel, from the end of one of said side panels towards the rear panel; and
(iii) folding the rear panel tab so that it is normal to the base section and extends transverse to the side panel tab.
In accordance with the invention, there is also provided a pizza box formed in accordance with the above described method.
The pizza box is assembled from the blank in an efficient manner, working from the front of the base section of the blank, towards the back of the base section and then finally to the lid section. In doing so, the pizza box is assembled in one smooth action, all in one assembly flow direction. This represents a significant improvement in speed of assembly over the prior art pizza boxes that require the user to change the assembly flow direction one or more times. The features of the blank are, advantageously, easy to fold into their assembled positions.
When assembled, the first and second rear comer rollovers improve the rigidity of the pizza box.

The pizza box 10 shown in Figures 1 to 4 is formed from the blank 12 shown in Figure 5. The blank includes:
(a) a planar base section 14 hingedly coupled to a corresponding planar lid 16 section by a rear panel 18 arranged therebetween;
(b) a front rollover 20 hingedly coupled to a front end of the base section 14, the front rollover 20 being arrangable to extend normally to the base section 14 in the manner shown in Figure 7c and 7d;
(c) first and second side wall panels 22,24 hingeldy coupled to respective opposed sides of the base section 14, the side wall panels 22,24 being arrangable to extend normally to the base section 14;
(d) locking tabs 26,28 hingedly coupled to respective ends of the first and second side wall panels 22,24, the locking tabs 26,28 being arrangable so that the front rollover 20 folds over the locking tabs 26,28 when the side wall panels 22,24 are normal to the base section 14;
(e) first and second rear comer rollovers 30,32, each comprising:
(i) a right angled triangular panel 34 with its hypotenuse 36 hingedly coupled to a stepped in rear comer section of the base section 14;
(ii) a rear panel tab 38 hingedly coupled between an end of the rear panel 18 and a rear side 40 of the triangular panel 34; and
(iii) a side panel tab 42 hingedly coupled between an end of one of said side panels 22,24 and another side 44 of the triangular panel 34.
In the embodiment shown in Figures 5 and 6, the following lines are shown:
(a) solid lines within the boarder of the blank 12 are cut lines;
(b) dash-dot lines are cut-crease lines; and
(c) dashed lines are lines of fold lines.
The blank 12 preferably has the dimensions shown in Figure 6. Alternative embodiments of the invention use other suitable combinations of dimensions that are desirable for pizza boxes.
As particularly shown in Figure 5, the side panel tab 42 of each rear comer rollover 30,32 is hingedly coupled to the triangular panel 34 in two spaced apart locations 46a, 46b, each proximal to respective vertex of trianglular panel 34.
As shown in Figures 2 and 3, the triangular panel 34 of each rear comer rollover 30,32 is hingedly coupled to the stepped in comer of the base section 14 in two spaced apart locations 48a, 48b, each proximal to respective vertex of trianglular panel 34.
As shown in Figure 5, a non-normal vertex 50 of the triangular panel 34 proximal to the side panel 42 is rounded. The rounded vertex 50 of the triangular panel 34 is a cut line. As also shown in Figure 5, another non-normal vertex 52 of the triangular panel 34 is blunt. The blunt vertex 52 is a cut line. Vertex 50 is curved to remove any potential nip points as the angle is more acute than in position where the straight line is suitable.
The front rollover 20 includes outer and inner wall panels 54,56 separated by a bridging section 58. The bridging section 58 separates the outer and inner wall panels 54,56 so that the locking tabs 26,28 can fit therebetween.
The inner wall panel 56 includes spaced apart locking tabs 60 that are shaped to mate with locking slots 62 formed in the base section 14. The locking slots 62 are shaped to at least partially receive the locking tabs 60 when the front rollover is erected to secure the front rollover in a fixed position.
The lid section 16 includes:
(a) side panels 64,66;
(b) front panel 68; and
(c) finger pull 70.
With reference to Figures 7a to 7g, the pizza box 10 is assembled from the blank 12 by performing the steps of:
(a) folding the side walls panels 22,24 so that they are normal to the base section 14 in the manner shown in Figure 7a;
(b) folding the locking tabs 26,28 inwardly so that they are normal to respective side wall panels 22,24 in the manner shown in Figure 7b;
(c) folding the front rollover 20 over the locking tabs 26,28 so that it is normal to the base section 14 in the manner shown in Figures 7c and 7d;
(d) folding the rear panel 18 so that is normal to the base section 14 in the manner shown in Figure 7e; and
(e) folding each of the first and second rear comer rollovers 30,32 in the following manner:
(i) folding the triangular panel 34 inwardly so that it overlies the base section 14; and
(ii) folding the side panel tab 42 so that it is normal to the base section 14 and extends diagonally, along the hypotenuse 36 of the triangular panel 34, from the end of one of said side panels 22,24 towards the rear panel 18; and
(iii) folding the rear panel tab 38 so that it is normal to the base section 14 and extends transverse to the side panel tab 42.
Finally, the side and front panels 64,66,68 of the lid section 16 are folded down in the manner shown in Figure 7f so that the box 10 can close in the manner shown in Figure 7g. The finger pull 70 remains coplanar with the lid section 16 when the front panel 68 is folded down. In doing so, the finger pull 70 acts as a grip point to open the lid 16.
The pizza box 10 is assembled from the blank 12 in an efficient manner, working from the front of the base section 14 of the blank 12, towards the back of the base section 14 and then finally to the lid section 16. In doing so, the pizza box 10 is assembled in one smooth action, all in one assembly flow direction. This represents a significant improvement in speed of assembly over the prior art pizza boxes that require the user to change the assembly flow direction one or more times. The features of the blank 12 are, advantageously, easy to fold into their assembled positions.
When assembled, the first and second rear comer rollovers 30,32 improve the rigidity of the pizza box.
The internal size of the box 10 preferably has the following dimensions 281x281x38. Alternatively, the internal size of the box 10 preferably has the following dimensions 285x285x38. Of course, the box 10 could have any other suitable sizes in the range.
MATERIALS USED
The blank 12 is constructed, for example, in R flute (2.5mm in Caliper) with recycled white liner on the outside, recycled medium liner and a kraft inside liner. Alternatively, the blank 12 is constructed from any other suitable cardboard material.
DEBOSSING
As shown in Figure 8, the blank 12 preferably includes debossed trade mark indicia 100 formed in the lid 16. In the embodiment shown in Figure 8, the following lines are shown:
(a) solid lines within the boarder of the blank 12 are cut lines;
(b) dash-dot lines are cut-crease lines; and
(c) dashed lines are lines of fold lines.
The debossing indicia 100 is created using creasing rule similar to that used to create the folds but at a lower height to create an indent or deboss. This is applied by the cutting form on the rotary diecutter.
The debossed trade mark indicia 100 provides a unique way to brand the pizza box 10.
The blank 500 shown in Figure 9 is used to construct a pizza box (not shown) in a similar manner to the blank 12. The blank 500 includes similar features to that of the blank 12 and like parts are referenced with like numbers. Specifically, the blank 500 include:
