DETAILED DESCRIPTION OF THE INVENTION

(7) Turning to the drawing, FIG. 1 shows a progressive view of a divider before and after perforation severing. The divider is made of a die-cut board 10 (such as a paper board) that is die cut, scored and double-sided coated. The coating is 100% water-based, recyclable and compostable within 90 days in a properly managed landfill. A conventional perfecting press may be used to shape the divider and provide the score lines and coat both sides.

(8) When the die-cut board 10 is folded at the scores to form the divider chambers 15, there arises an alternating set of peak folds 12 and valley folds 14 at the scores.

(9) Each of the divider chambers 15 is bounded by a pair of panels 17 of the die-cut board 10 with one of the valley folds 14 between the pair of panels 17.

(10) There is at least one line of perforations that passes through the entire set of peak and valley folds. Preferably, there may be two lines of sideline perforations 16 and centerline perforations 18 (see FIGS. 1 and 5). The centerline perforations 18 would be spatially separated from and located centrally between the two sideline perforations, all of which lines of perforations 16, 18 being substantially parallel to each other.

(11) After severing the sideline perforations 16 and the centerline perforations 18, there would be left two divider halves 10A, 10B and two tapered strips 10C formed by severing the sideline perforations (only one shown in FIG. 1, but the other is symmetric or a mirror image). The two tapered edges 10C are to be discarded.

(12) The two divider halves 10A, 10B define the divider chambers 15, which are bounded by a pair of panels 11 of the associated divider half 10A, 10B that has a respective one of the valley folds 14 between the pair of panels 11.

(13) As a consequence of providing for such perforations, there arises flexibility as to the divider size. The divider size does not have to take up the full dimension of the box for take out to fulfill the function of retaining tacos separate from each other. If a side order from a menu is offered for take out, for instance, in addition to the tacos, the die-cut board 10 can be separated into halves by severing at the centerline perforation 18 that is provided for that purpose. As a result, two shorter divider halves 10A, 10B are formed that enable the tacos to be served with a side of rice or beans or a salad in the same box for take out. The divider halves 10A, 10B each have severed portions 40 of perforations along one of their edges where they were separated and thus corresponding ones of the severed portions 40 of perforations from each of the divider halves 10A, 10B complement each other.

(14) Turning to FIGS. 2 and 3, the die-cut board 10 (or each of die-cut halves 10A. 10B) has scores (peak folds 12, valley folds 14) that separate the divider chambers 15 from each other and are only at most 40% score depth of the total thickness of the die-cut board 10 so that the folded (accordion style) die-cut board 10 (or each die-cut half 10A, 10B), when folded, has a maximum amount of dead fold resistance, memory (or spring back).

(15) When the die-cut board 10 is placed in a box (such as the tapered box 30 of FIG. 3) for take-out and released from its fully folded condition under manual force, the release causes the die-cut board 10 to spring back (tending to unfold) so as to have the die-cut board 10 fully cover the chamber floor of the box with end edges of the die-cut board 10 coming into contact with and pressing the opposite walls of the box.

(16) Turning to FIG. 2, the two divider halves 10A, 10B are shown within the confines of a non-tapered box 20 that is of a rectangular straight wall style. The two divider halves 10A, 10B are shown flipped over relative to each other. That way, divider half 10A has three divider chambers topside and divider 10B has two divider chambers topside. That is, there is a different number of divider chambers facing topside as between the two halves 10A, 10B. The two divider halves 10A, 10B rest upon a topside of the bottom of the non-tapered box 20.

(17) In practice, only one of the two divider halves 10A, 10B would be placed in any one box to accommodate one order of tacos, but the other would be placed in another box to accommodate another order of tacos. The remaining space in the box (with just one of the two divider halves 10A, 10B in the box) could accommodate other food items from the menu, such as rice or beans or salad.

(18) There may be no need, however, to sever the sideline perforations 16 once the centerline perforations 18 are severed, because either one of the two divider halves 10A, 10B, even with the taper strips attached, will fit within the non-tapered box 20.

(19) That is, the underside of either of the two divider halves may rest upon the top of the bottom of the box.

(20) Turning to FIG. 3, the die-cut board 10 is positioned within a tapered box 30 whose sidewall 32 tapers from top to bottom. The sides of the die-cut board 10 are shaped to taper in a complementary manner to the taper of the box sidewall 32. The sides of the die-cut board 10 taper from the peak folds to neighboring ones of the valley folds and thus from top to bottom. Inserting the die-cut board 10 into the tapered box 30 results in the tapered sides of the die-cut board 10 being accommodated upon or against the tapered sidewall 32 of the tapered box 30 so that the bottom side of the divider clears the tapered sidewall 32 to rest upon the topside of the bottom of the tapered box 30.

(21) However, flipping the die-cut board 10 over would mean it would not fit into the tapered box 30 in that orientation. This is because the underside of the divider 10 after flipping is too large to clear the inward taper of the tapered box 30 and thus could not reach the top of the bottom of the tapered box 30 to rest upon it.

(22) For that reason, severing the sideline perforations 16 and discarding them yields the die-cut board 10 but without the side taper and thus is dimensioned to clear the sidewalls 32 of the tapered box 30 after being flipped over and thus be able to rest upon the topside of the bottom of the tapered box 30. Such perforation severing offers the flexibility to flip the (non-tapering) die-cut board 10 over to give a user the choice as to the number of divider chambers or divider chambers 15, which are V-shaped, that will face topside and thus a corresponding number of tacos that can be placed into the V-shaped chambers for retention. Each divider chamber 15 has a pair of panels 17 that incline from a single valley fold between them to form the V-shape.

(23) If the divider has, for instance, three divider chambers 15 formed on one face to accommodate retaining three tacos and has two divider chambers 15 formed on the opposite face that can accommodate two tacos (albeit slightly larger tacos than is the case for the one face), then severing the centerline perforations 18 to remove the taper enables the divider to be accommodated in the box to rest on the topside of the bottom of the box with either the two divider chamber 15 face or the three divider chamber 15 face being on top.

(24) As an alternative or in addition, the die-cut board 10 could also be severed at the centerline perforations 18. Either of the resultant two divider halves 10A, 10B would fit within the tapered box 30, with or without the tapered side attached.

(25) As a further alternative, if the tapered box 30 could be replaced by a non-tapered box 20 of FIG. 1 of large enough dimension, then the die-cut board 10 would fit the box and may rest on the topside of the bottom of the non-tapered box 20 in either of its orientations, i.e., with the three-divider chamber 15 face topside or with the two-divider chamber 15 face topside.

(26) Turning to FIG. 4, it should be apparent that the die-cut board 10 has three-divider chambers 15 in one side and two-divider chambers 15 in the opposite side. Thus, if the two-divider chambers 15 are topside, in a box, one can flip the die-cut board upside down and the three-divider chambers 15 then are positioned topside instead and vice versa.

(27) While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the scope of the present invention.
