Cake box

Abstract

A cake packaging employs special locks that allow bakers and bakery customers to open and close the packaging without risk of damaging the cake inside, but the elements work together so the fully-erected structure hides the less-than-sleek geometry of the locking mechanisms even as these obscuring panels are tucked into one another to secure the panels and give the packaging strength.

1 . A unitary sheet material formable into a box structure, comprising:
 a bottom panel with a right side panel, a left side panel, a front panel and a rear panel, that extend laterally outward from the bottom panel;   a closure flap that extends laterally outwardly from a right and a left side of each of the front panel and the back panel;   an arcuate slot defined laterally across a mid portion of the right side panel and the left side panel;   a securement tab defined at each of a lower end and an upper end of the closure flap, protruding in an upward and a downward direction, respectively, at an end of the closure flap distal to the respective front panel and rear panel; and   a closure notch defined in the right side panel and the left side panel along a top margin of the right side panel and the left side panel, wherein a lower securement tab is configured to be received within the arcuate slot and an upper securement tab is received in the closure notch to join at least one of the front panel or the rear panel to at least one of the right side panel or the left side panel.   
     
     
         2 . The unitary sheet material of  claim 1 , further comprising:
 a top panel extending from the rear panel along an edge opposite the bottom panel.   
     
     
         3 . The unitary sheet material of  claim 2 , further comprising:
 a tuck flap extending outwardly for the lateral sides of the top panel, wherein the tuck flap is configured to be received within the arcuate slot during closure of the top panel.   
     
     
         4 . The unitary sheet material of  claim 3 , further comprising:
 a top latch extending from an edge of the top panel opposite the edge connecting the top panel to the bottom panel.   
     
     
         5 . The unitary sheet material of  claim 4 , further comprising:
 a latch tab protruding from a distal edge of the top latch.   
     
     
         6 . The unitary sheet material of  claim 5 , further comprising:
 a latch notch defined along an upper margin of the front panel, wherein the latch notch is dimensioned to receive the latch tab.   
     
     
         7 . The unitary sheet material of  claim 1 , further comprising:
 a score line defined along a boundary between the bottom panel and one or more of the right side panel, the left side panel, the front panel, the rear panel.   
     
     
         8 . The unitary sheet material of  claim 1 , further comprising:
 a score line defined along a boundary between the side panel and the closure flap.   
     
     
         9 . The unitary sheet material of  claim 4 , further comprising:
 a score line defined along a boundary between the top panel and one or more of the tuck flap and the top latch.   
     
     
         10 . The unitary sheet material of  claim 1 , wherein a spacing between a base of the upper securement tab and a base of the lower securement tab is at least a spacing between the arcuate slot and a top edge of the closure notch.
