The following specification particularly describes the invention and the manner in which it is to be performed

FIELD OF THE INVENTION:
The present disclosure relates to packaging boxes for packaging articles and a method of manufacturing the packaging boxes in minimal steps of folding, more particularly, the present disclosure relates to a tamper evident packaging box having an integrally formed sealing arrangement.
BACKGROUND
Packaging cartons have been in use since decades for packaging various edible and non- edible items like chocolates, sweets, gift items and the like. Most of the packaging cartons which have been in use before and are now in use are sealed for preventing insects, moisture, and the like from entering the carton and deteriorating the contents of the carton. Most of the packaging cartons are made air-tight in order to preserve the contents thereof for a longer duration of time.
Further, most of the packaging cartons are provided with sealing means for protecting the contents of the packaging cartons against adulteration by the handling personnel. More often, the packaging cartons are sealed for preventing of altering of contents thereof. However, such packaging cartons are usually prone to frequent tampering and adulteration thereby of contents thereof and, thereby jeopardizing the safety and quality assurance of produce provided in cartons for the companies and, more importantly for, the consumers.
Most of the sealing means incorporated in the packaging cartons of the prior art fail to provide a permanent and visible indication as to whether the packaging carton and the contents thereof have been tampered with. Further, most of the sealing means incorporated in the packaging cartons may lead to compromise on the aesthetic appearance of the package carton. Further, the

conventional packaging boxes with tamper evident sealing configured thereto are complex and difficult to manufacture. Further, the conventional packaging boxes lack integrally configured sealing arrangement that is easy and simple to assemble once manufactured.
Accordingly, there is need for a packaging carton that addresses the problem faced by the conventional packaging cartons. More specifically, there is a need for a packaging carton configured with a tamper evident sealing means that not only provide a permanent and visible indication as to whether the packaging carton and the contents thereof has been tampered with but also enhances aesthetic appeal of the packaging carton. Furthermore, there is need for a packaging carton with tamper evident sealing configured there-to that is simple in construction and convenient to manufacture.

Figure 1 of the accompanying drawings illustrate a single blank of sheet 100 in an unfolded configuration, folded along the fold lines for configuring a packaging box configured with a tamper evident sealing means in accordance with an embodiment of the present invention. The different panel-portions configuring the single blank of sheet 100 are folded along the fold lines along the direction of arrows illustrated in Figure 1 to Figure 17 for configuring the packaging box as illustrated in Figure 17. Packaging box is preferably made of materials such as sand papers, hard boards, plastics that are foldably assemblable.

The blank of sheet 100 includes panels 2, 4, 6 and 8 and longitudinal fold lines 12 and 14 that coincide with longitudinal edges. The panel 2 includes a wall portion 2a that also defines a front wall of the box, and a bottom flap 2b and a top flap 2c; the panel 4 includes a wall portion 4a that defines a left side wall of the box, and a bottom flap 4b and a top flap 4c; the panel 6 includes a wall portion 6a that defines a rear wall of the box when the box is formed in a closed position; and the panel 8 includes a wall portion 8a that defines a right side wall of the box when the box is formed. The panel 6 has a bottom flap 6b and a top flap 6c and the panel 8 includes a bottom flap 8b and a top flap 8c.
The bottom flap 2b of panel 2 is hinged to front side wall 2a along fold line 12, whereas the top flap 2c of the panel 2 is hinged to the front side wall 2a along the fold line 14. The bottom flap 4b of the panel 4 is hinged to the left side wall 4a along the fold line 12 and the top flap 4c of panel 4 is hinged to the left side wall 4a along the fold line 14. The bottom flap 6b of the panel 6 is hinged to the rear side wall 6a along the fold line 12 and the top flap 6c of the panel 6 is hinged to the rear side wall 6a along the fold line 14. The bottom flap 8b of the panel 8 is hinged to the right side wall 8a along fold line 12, whereas the top flap 8c of the panel 8 is hinged to right side wall 8a along fold line 14.
In other words, the bottom flaps 2b, 4b, 6b and 8b are folded along fold line 12 whereas the top flaps 2c, 4c, 6c and 8c are folded along fold line 14 when the box is formed.
The front wall 2a is hinged by a vertical fold line 13a that coincides with a vertical crease and is perpendicular to fold lines 12 and 14 to the left side wall. The left side wall 4a hinged by a vertical fold line 13b that coincides with a vertical crease and is perpendicular to fold lines 12 and 14 to the rear side wall 6a. The rear wall 6a is hinged by a vertical fold line 13c that coincides with a vertical crease and is perpendicular to fold lines 12 and 14 to the right side wall 8a.
In other words, fold lines 13a, 13b, 13c and 13d separate an define contiguous panels 2, 4, 6, 8.

The panel 8 also has an end tab 8t that is approximately trapezoidal in shape and is foldable along a fold line 13d that coincides with a vertical crease and is perpendicular to fold lines 12. The end tab 8t is hinged to right side wall 8a.
The top flap 2c has a pair of side tabs 500 and 502 that are approximately trapezoidal in shape. The tabs 500 and 502 are hinged by minor fold lines 504 and 506 to the top flap 2c. The top flap 2c has a tab 508 that is semicircular in shape. The semicircular tab 508 is hinged by a minor fold line 510 to the top flap 2c. The height of the top flap 2c is less than the width of the left side wall 4a.
The top flap 6c has a proximal portion 512 and a distal portion 514 that are divided by a fold line 516. The fold line 516 is interrupted by a transversal cut 518 that is semicircular in shape and is located at the centre. The proximal portion 512 preferably has rounded edges. The distal portion 514 has a couple of side tabs 520 and 522 that are approximately trapezoidal in shape. The tabs 520 and 522 are hinged by minor fold lines 524 and 526 to the distal portion 514. The height of the top flap 6c is at approximately equal to the addition the width and height of left side wall 4a.
The bottom flaps 2b and 6b of the panels 2 and 6 respectively are approximately trapezoidal in shape. The bottom flaps 4b and 8b of the panels 4 and 8 respectively are rectangular in shape and have a cut of approximately triangular conformity at the distal end. The bottom flaps 4b and 8b have sub-flaps 528 and 530 that are foldable along slanting fold lines 532, 534 on the bottom flaps 4b and 8b respectively. The panel 4 has a transversal cut 536 approximately centrally located on the border of top flap 4c and left side wall 4a that receives tabs to restrict the lateral movement. The panel 4 has a transversal cut 538 approximately centrally located on the border of bottom flap 4c and left side wall 4a that receives tabs to restrict the lateral movement of flaps 2c and 6c.

The top flap 8c includes an integrally formed vertically extending strip extension 10. The strip extension is a that acts as a "ribbon" or a "latch" or a "seal" when the box is formed out of the blank 100 in a closed position. Therefore, the terms "ribbon", "latch" and "seal" are also used alternately for the strip extension 10. The extension 10 is flanked by a pair of side flaps 540, 542. The side flaps 540 and 542 are folded along minor fold lines 544 and 546 respectively when the box is formed. When the flanking side flaps 540, 542 are folded an opening 545 is defined. The opening 545 receives side tabs from panels 2 and 6.
The strip extension 10 has an integrally formed aesthetic element 548 located between minor fold lines 550, 552. The distance between fold lines 550 and 552 is approximately equal to width of the rear side wall 6a. There is an auxiliary flap 554 at the end of the strip extension 10. The auxiliary flap 554 has a couple of auxiliary tabs 556 and 558 that are divided by minor fold lines 560 and 562 respectively. The auxiliary flap 554 is divided from the rest of the strip extension by a minor fold line 564. There is an anti-tamper tearable section 20 within perforated lines 20a and 20b. The result of subtraction of the height of the auxiliary flap 554 from the height of the strip, that is, the distance between minor fold lines 564 and 550, is approximately the equal to the addition of height and width of the rear wall.
Now, the method of forming box from the blank of sheet 100 that is in an unfolded configuration or an open position in accordance with the preferred embodiment of the present invention is described.
In order that the package box having an integrally configured anti-tamper ribbon 10 be formed in accordance with the present invention, first, as shown in Figure 1, the blank of sheet 100 is provided in a planar manner, that is, in an unfolded configuration.

As shown in Figures 2-5, the bottom flaps 2b, 4b, 6b and 8b are folded as indicated by arrows Al, A2, A3 and A4 respectively. The fold is along the longitudinal fold line 12. The sub-flaps 528 and 530 are pivoted as indicated by arrows Bl and B2 along the slanting fold lines 532 and 534 respectively. The panel 8 is folded along the fold line 13c as indicated by arrow B3. The panel 2 is folded as indicated by arrow B4 perpendicular to the fold lines 12 and 14. The partly folded panel 2, wherein the bottom flap 2c is folded, is pivoted as indicated by arrow B4 perpendicular to the fold lines 12 and 14 and the stage for locking of the bottom portion of the packaging box is set.
As shown in Figure 6-19, the panel 4 is hinged along as indicated by arrow Dl such that panel 4 is now perpendicular to the panels 2 and 6 and parallel to the panel 8. Therefore, as a consequence, the bottom flaps, 2b, 4b, 6b and 8b are folded towards each other and the box is folded up. Next, top flap 4c is pivoted down as indicated by arrow D3 and parallel to the bottom flap 4b. The flanking side flaps 540 and 542 of the panel 8 are folded as indicated by arrows D4, D5 and parallel to the bottom flap 8b. Next, the side tabs 520, 522 of the panel 6 are folded as indicated by arrow D6 and are now approximately perpendicular to proximal portion 514 of the panel 6. The distal portion 512 of the panel 6 is hinged as indicated by arrow D7 and is now approximately perpendicular to the proximal portion 514. Next, the top flap 6c of the panel is pivoted downwards as indicated by arrow D8. Now, the top portion or top face of the box is formed and the distal portion 512 of the panel 6 is inserted inside the box in a closed position. Next, the top flap 2c of the panel 2 is pivoted as indicated by arrow D9 and the side flaps 502, 502 of the top flap 2c are inserted inside the transversal cut 538 and the opening that is created by folding of side flanks respectively. Next, the ribbon 10 is pivoted as indicated by arrow Dl 1 such that the ribbon 10 lies on top of the top surface of the box. The ribbon is then hinged along the fold line 552 as indicated by arrow El. Next, the side tabs 556 and 558 of the auxiliary flap 554 folded as indicated by arrows E2, E3.The tabs 556, 558 are then inserted into the transversal cut 538 as indicated by arrow E4 and then unfolded inside as indicated by arrows E5. The tabs 556 and 558 the provided a locking mechanism against tampering when presented in the planar

manner inside the box. Thus, the packaging box in accordance with the present invention is assembled.
The packaging box now includes a top face 100a, a bottom face 100b (not shown in Figure 17), a left hand side face 100c, a right hand side face lOOd (not shown in Figure 17), a front face lOOe and a rear face 1 OOf. More specifically, the packaging box in this preferred embodiment is a top opening type packaging box, wherein the top face 100a of the packaging box may be opened for accessing the interior of the packaging box and the ribbon 10 may overlie the top face 100a of the packaging box extending from the left hand side face 100c to the right hand side face lOOd of the packaging box (as shown in Figure 17).
The ribbon 10 may extend between any other opposite sides of the packaging box, accordingly the blank of sheet 100 may be modified. The tabs 556 and 558 are adapted to define a lock of the packaging box. In this preferred embodiment, the tabs 556, 558 are foldable along the fold lines 560, 562 such that the tabs 556, 558 in folded conformity are adaptable to be engaged with a transverse cut 538. Once inserted into the cut 538 the tabs 556, 558 unfold and lock inside the cut 538. The tearable section 20 is permanently and visibly torn-off when the box is opened or tampered with. Even the slightest force exerted on the ribbon is enough to break the seal apart.
In alternate embodiment, instead of an auxiliary flap a free end of the ribbon 10 may be sealed or adhered with a sealant or adhesive material in close proximity to the tearable section
Referring to Figure 19, for accessing the contents of the packaging box for the first time, the tearable section 20 may be teared-off along tear-lines 20a and 20b for permanently opening the tamper evident seal and accessing an interior of the packaging box. As the tearable section 20 is separated from the ribbon 10, the free end 10a of the ribbon 10 thus formed is tucked into the cut 30 configured on an top edge of the left side face 100c of the packaging box, as illustrated in

Figure 20 and Figure 21 of the accompanying drawings. All the essential elements of the packaging box 100 such as the ribbon 10, the tearable section 20 configured on the ribbon 10, the tear-lines 20a and 20b configured on the tearable section 20, the slot 30 are all configured by a single blanking action, thereby resulting in considerable time saving during the manufacturing of the packaging box. Packaging box is preferably made of materials such as sand papers, hard boards, plastics that are foldably assemblable.
In an alternate embodiment of the present invention, a unique pattern can be created by the tear-lines 20a and 20b. Any tampering attempt of the packaging box will result in disrupting the unique line pattern irreparably resulting loosing of ribbon 10. In case one attempts to reseal the tear-lines 20a and 20b by an adherent or an adhesive, resealing would result in mismatch of the line pattern.
In yet another embodiment of the present invention, ribbon 10 includes a plurality of tearable sections 20 that are positioned at predefined locations on the ribbon 10 to indicate any tampering activity from any face of the packaging box.
In yet another embodiment of the present invention, a plurality of ribbons 10 are employed. The plurality of ribbons 10 may be used with packaging boxes having more or less than sides or faces. Therefore hexagonal packaging boxes, even packaging boxes having three sides or faces, may be used instead of a rectangular shape.
Figure 22 of the accompanying drawings illustrate a single blank of sheet 200 in an unfolded configuration, folded along the fold lines for configuring a packaging box configured with a tamper evident sealing means in accordance with another preferred embodiment of the present invention.

The blank of sheet 200 includes panels 602, 604, 606 and 608 and longitudinal fold lines 612 and 614 that coincide with longitudinal edges. The panel 602 includes a front face portion 602a and a bottom flap 602b and a top flap 602c of panel 604.

The bottom flap 604b of panel 604 is hinged to top face portion 604a along fold line 612, whereas the top flap 604c of panel 604 is hinged to top face portion 604 along fold line 614. The bottom flap 606b of panel 606 is hinged to rear face portion 606a along fold line 612, whereas the top flap 606c of panel 606 is hinged to rear face portion 606a along fold line 614. The bottom flap 60Sb of panel 608 is hinged to bottom face portion 608a along fold line 612, whereas the top flap 608c of panel 608 is hinged to bottom face portion 608a along fold line 614. In other words, the bottom flaps 602b, 604b, 606b and 608b are folded along fold line 612 whereas the top flaps 602c, 604c, 606c and 608c are folded along fold line 614 when the box is formed.
The width of top and bottom flaps 602c and 602b of the panel 602 is slightly less than the width the of front face portion 602a. The width of top and bottom flaps 606c and 606b of the panel 606 is slightly less than the width the of front face portion 606a. The width of top and bottom flaps 604c and 604b of the panel 604 is approximately equal to the width the of top face portion 604a. The width of top and bottom flaps 604c and 604b of the panel 604 is approximately equal to the width the of top face portion 604a. The difference between widths of top and bottom flaps 602c, 602b, 606c, 602b and face portions 602a and 606a of panels 602 and 604 defines openings that facilitate easy and unhindered hinging of top and bottom flaps 604b, 604c, 608b, 608c of the panels 608 and 610.

The front face portion 602a is hinged by a vertical fold line 613a that coincides with a vertical crease and is perpendicular to fold lines 612 and 614 to the left side wall. The top face portion 604a is hinged by a vertical fold line 613b that coincides with a vertical crease and is perpendicular to fold lines 612 and 614 to the rear face portion 606a. The rear face portion 606a is hinged by a vertical fold line 613c that coincides with a vertical crease and is perpendicular to fold lines 612 and 614 to the bottom face portion 608a. The fold lines 613a, 613b, 613c and 613d are approximately perpendicular to the longitudinal fold lines 612 and 614.
The panel 608 also has an elongated end tab 608t that is approximately trapezoidal in shape and is foldable along a fold line 613d that coincides with a vertical crease and is perpendicular to fold lines 612. The end tab 608t is hinged to bottom face wall portion 608a.
The front face portion 602a is hinged to the top face portion 604a along fold line 613a; the top face portion 604a is hinged to the rear face portion 606 along fold line 613 b; the rear face portion 606a is hinged to the bottom face portion 608b along fold line 613c; and the bottom face portion is hinged to the tab 608 by fold line 613d.
The top flap 604c of the panel 604 has a vertically extending tab 700 that is approximately trapezoidal in shape. The tab 700 is hinged by minor fold 702 to the top flap 604c of the panel 604. The bottom flap 604b of the panel 604 has a vertically extending tab 704 that is approximately trapezoidal in shape. The tab 704 is hinged by minor fold 706 to the bottom flap 604b of the panel 604.
The top flap 608c of the panel 608 includes an integrally formed and vertically extending strip extension 110 that acts as a "ribbon" when the box is achieved out of the blank 200 in a closed position. The extension 610 is flanked by a pair of side flaps 706, 708. The side flaps 706 and 708 are folded along minor fold lines 710 and 712 respectively when the box is formed. The fold

lines 710 and 712 coincide with the fold line 614. The side flap 706 has an approximately centrally located transversal cut 714 along the fold line 710. The cut 714 is configured to receive the tab 700 when the box is in closed potion. The width of the cut 714 is approximately equal to the width of the top flap 602c of the panel 602.
The bottom flap 608b of the panel 608 has two transversal cuts 716 and 718 along the fold line 612. The width of the cut 716 is approximately equal to the width of bottom cut 602b. The cut 718 is configured to receive the tab 704 when the box is in closed position. The width of cut 718 is approximately equal to the width the strip extension 110 and the cut 718 is configured and positioned to receive the strip extension 110.
The strip extension 110 has an integrally formed aesthetic element 720 located between minor fold lines 722, 724. The distance between fold lines 722 and 724 is approximately equal to width of the bottom face portion 608a. There is an auxiliary flap 726 at the end of the strip extension 110. The auxiliary flap 726 has a pair of auxiliary tabs 728 and 730 that are divided by minor fold lines 732 and 734 respectively. The auxiliary flap 722 is divided from the rest of the strip extension by a minor fold line 736. The result of subtraction of the height of the auxiliary flap 722 from the height of the strip extension 110, that is, the distance between minor fold lines 722 and 736, is approximately equal to the result of addition of the height of the bottom face portion 608a and the height of the bottom flap 608b of the panel 608.
Now, the method of forming box from the blank of sheet 200 that is in an unfolded configuration or an open position in accordance with another preferred embodiment of the present invention is described.

In order that the package box having the integrally configured anti-tamper ribbon 110 is assembled in accordance with the present invention, first, as shown in Figure 22, the blank of sheet 200 is provided in a planar manner, that is, in an unfolded configuration.
As shown in Figures 22-41, the panel 602 of the blank 200 is folded along the fold line 613a as indicated by arrow Fl and the panel 604 is pivoted along the fold line 613b.The end tab 608t is folded along the fold line 613d and the panel 602 and the end tab 608t are brought closer together to form a top face and a bottom face of the box being assembled as indicated by arrows F2 and F3. Next, as indicated by arrows F4 and F5, the bottom flaps 602b and 606b are folded along the fold line 612 to be approximately perpendicular to the panels 604 and 608. The bottom flap 604b of panel 604 is pivoted along the fold line 612 as indicated by arrow F6 such that the bottom flap 604b is perpendicular to the panels 602 and 606 that are parallel to each other. Next, the tab 704 of the bottom flap 604b is inserted into the transversal cut 716 to lock the bottom flaps 604b and 608b and restrict the lateral movement. The strip extension latches and seals the length and the height of the contiguous panel.
Similarly, the top flaps 602c and 606b are folded along the fold line 614 to be approximately perpendicular to the panels 604 and 608 as indicated by arrows F8 and F9. The tab 700 of the top flap 604c is inserted into the transversal cut 714 to lock the top flaps 604c and 608c and restrict the lateral movement. The flanking side flaps 706 and 708 are fold along fold lines 710 and 712 to be approximately perpendicular to the adjoining panel 608 and the panel 604. Next, as indicated by arrow F12, the top flap 604c of panel 604 is pivoted along the fold line 614 as indicated by arrow F6 such that the top flap 604c is perpendicular to the panels 602 and 606 that are parallel to each other. Next, the ribbon is hinged along the fold line 722 as indicated by arrow F13. As indicated by arrow G2 the ribbon is folded along the fold line 722, The tabs 728 and 730 of the auxiliary flap 726 are folded along the fold lines 732 and 734 as indicated by arrows G3 and G4 respectively. The auxiliary flap 726 with folded tabs is inserted into the transversal cut

718. Next, the tabs 732, 734 unfold and lock inside the cut 718. The packaging box in accordance with another preferred embodiment of the invention is thus assembled.
The different panel-portions configuring the single blank of sheet 200 are folded along the fold lines along the direction of arrows illustrated in Figure 22 to Figure 36 for configuring the packaging box as illustrated in Figure 37.
The packaging box as illustrated in Figure 37 includes a top face 200a, a bottom face 200b (not shown in Figure 37), a left hand side face 200c, a right hand side face 200d (not shown in Figure 37), a front face 200e and a rear face 200f (not shown in Figure 37). The packaging box as illustrated in Figure 37 configured by folding the single blank of sheet 200 along the fold lines and along the direction of arrows illustrated in Figure 22 to figure 36 includes at-teast one ribbon 110 integrally configured thereto acting as a tamper evident seal. More specifically, the packaging box is a side opening type packaging box, wherein the right side face 200d of the packaging box may be opened for accessing the interior of the packaging box and the ribbon 110 may overlie the right side face 200d of the packaging box extending from the bottom face 200b to the top face 200a of the packaging box (as shown in Figure 37).
The ribbon 110 may extend between any other opposite sides of the packaging box; accordingly the blank of sheet 200 may be modified. The ribbon 110 includes a tearable section 120 configured thereon. Ribbon 110 may include a plurality of tab at one end that is adapted to define a lock of the packaging box. In this preferred embodiment, the plurality of tab are foldable along the fold lines such that the tab in folded conformity adaptable to engage with a pocket on the opposite face of the packaging box. Folded tab unfolds once inserted in to the pocket attaining flat confirmation such that free end of the ribbon 110 is locked in the pocket of the packaging box.

In alternate embodiment, free end of the ribbon 110 may be sealed or adhered with a sealant or adhesive material in close proximity to the tearable section 120 such that any tampering attempt of the packaging box will result in break on tearbale section 20 irreparably resulting loosing of ribbon 110.
Referring to Figure 39 of the accompanying drawing, for accessing the interior of the packaging box for the first time, the tearable section 120 may be teared-off along tear-lines 120a and 120b for permanently opening the tamper evident seal and accessing an interior of the packaging box. As the tearable section 120 is separated from the ribbon 110, the free end 110a of the ribbon 110 thus formed is tucked into the slot 130 configured on an top edge of the left side face 200c of the packaging box, as illustrated in Figure 40 and Figure 41 of the accompanying drawings. All the essential elements of the packaging box 200 such as the ribbon 110, the tearable section 120 configured on the ribbon 110, the tear-lines 120a and 120b configured on the tearable section 120, the slot 130 are all configured by a single blacking action, thereby resulting in considerable time saving during the manufacturing of the packaging box 200.
In an alternate embodiment of the present invention, a unique pattern can be created by the tear-lines 120a and 120b. Any tampering attempt of the packaging box will result in disrupting the unique line pattern irreparably resulting loosing of ribbon 110. In case one attempts to reseal the tear-lines 120a and 120b by an adherent or an adhesive, resealing would result in mismatch of the line pattern. Unique pattern additionally adds as evidence to the tampering.
In yet another embodiment, the number of panels may vary. The number and positioning of tabs also may vary in yet other embodiments. There may be more than one strip extension or ribbon.The number and positioning of transversal cuts and slits may vary in other embodiments.

In yet another embodiment of the present invention, ribbon 110 includes a plurality of tearable sections adaptably positioned at predefined locations on the ribbon 110 to indicate any tampering activity from any faces of the packaging box: Plurality of tearable section would result in flapping of the ribbon 10 such that flapping will indicate attempt of forced entry.
