Description

BACKGROUND

This disclosure relates generally to containers formed from blanks of sheet material, and, more specifically, to a blank of sheet material for forming a container, and methods and apparatus for forming the container.

Corrugated board containers are often used to hold granular products (e.g., sugar, flour, or cat litter) or other articles. If the container has a crack or small opening, then some of the product might escape the container by sifting. In order to prevent this, a manufacturer might use additional packaging, such as adding a plastic bag or another kind of insert. The addition of such bags or inserts makes such containers more costly to manufacture and require more attention in making them. For example, such containers may require a more sophisticated type of machine to manufacture them.

Panels 22, 24, 26, 28, 30, 32, 34, 36, 38 are coupled together by a plurality of generally parallel fold lines 42, 44, 46, 48, 50, 52, 54, 56, respectively. In one embodiment, fold lines 42, 44, 46, 48, 50, 52, 54, 56 are preformed. In the example embodiment, each of panels 22, 24, 26, 28, 30, 32, 34, 36, and 38 is substantially rectangular. In other embodiments, any of panels 22, 24, 26, 28, 30, 32, 34, 36, and/or 38 may have any size, shape and/or configuration that enables blank 10 and container 700 to function as described herein.

As shown in FIG. 1, second end panel 38 extends from second minor panel 36 along fold line 56; second minor panel 36 extends from third intermediate panel 34 along fold line 54; third intermediate panel 34 extends from second major panel 32 along fold line 52; second major panel 32 extends from second intermediate panel 30 along fold line 50; second intermediate panel 30 extends from first minor panel 28 along fold line 48; first minor panel 28 extends from first intermediate panel 26 along fold line 46; first intermediate panel 26 extends from first major panel 24 along fold line 44; and first major panel 24 extends from first end panel 22 along fold line 42.

First end panel 22 has a width W₁. Second end panel 38 has a width W₂. Similarly, first intermediate panel 26 has a width W₃; second intermediate panel 30 has a width W₄; and third intermediate panel 34 has a width W₅. In the embodiment shown in FIG. 1, widths W₁, W₂, W₃, W₄, and W₅ are substantially equal. In alternative embodiments, any of widths W₁, W₂, W₃, W₄, and W₅ may be other than substantially equal to any other of widths W₁, W₂, W₃, W₄, and/or W₅ without departing from the scope of the present disclosure. Additionally, each minor panel 28, 36 has a respective width W₆, W₇. In the example embodiment, widths W₆ and W₇ are substantially equal.

Access tab 550 includes a first side edge 554 and an opposing second side edge 556. Access tab 550 further includes a third side edge 558 opposite the fold line along top edge 88. First side edge 554 defines a first side portion 555 of second minor panel 36 along fold line 54, second side edge 556 defines a second side portion 557 of second minor panel 36 along fold line 56, and third side edge 558 defines an intermediate edge 559 of second minor panel 36 substantially perpendicular to first and second side portions 555, 557. Each of first side edge 554, second side edge 556, and third side edge 558 is generally formed as a line of weakness. As used herein, the term “line of weakness” refers to any preformed line, such as but not limited to score lines, perforation lines, or lines of separation, along which the blank material is configured to have a relatively decreased resistance to folding or tearing.

Access tab 550 further includes a punch-out tab 552. A perimeter of punch-out tab 552 is defined by a fold line 560, a first side edge 562, an opposing second side edge 564, and a third side edge 566 opposite fold line 560. Third side edge 566 defines a portion of third side edge 558 of access tab 550. Each of first side edge 562, second side edge 564, and third side edge 566 is generally formed as a line of weakness.

A consumer may open container 700 (e.g., access a cavity 710 defined therein) by applying a pushing force to the exterior surface 14 punch-out tab 552. Punch-out tab 552 decouples from access tab 550 along side edges 562, 564, 566 and rotates about fold line 560 into cavity 710 through an opening (not shown) defined by the perimeter of punch-out tab 552. The consumer is then able to contact interior surface 12 of access tab 550. The consumer applies a pulling force to access tab 550, such that access tab 550 decouples from second minor panel 36 along side edges 554, 556, and 558. Access tab 550 rotates about the fold line at top edge 88. First side portion 555 of second minor panel 36, second side portion 557 of second minor panel 36, intermediate edge 559 of second minor panel 36, and top edge 88 define an access opening 804 (shown in FIG. 8) to cavity 710 of container 700. Accordingly, in such an embodiment, second minor top flap 504 may be removed from container 700 when the consumer opens container 700 as described above. In other words, after the consumer decouples access tab 550 from container 700, the consumer may fully withdraw or remove second minor top flap 504 from container 700. Additionally or alternatively, an access tab similar to access tab 500 may extend from first minor top flap 502 into first minor panel 28 and function substantially identically as described with respect to access tab 550

In some embodiments, adhesive is applied to blank 10 in one or more adhesive regions 680, as shown in FIG. 1, such that container 700 may be formed from blank 10. Adhesive may be applied in adhesive regions 680 in strips, beads, dots, sheets, or in any other suitable manner. Additionally, adhesive need not be applied to an entirety of any adhesive region 680 but may be applied to only a portion of one or more adhesive regions 680. Alternatively, adhesive may applied to a greater portion of blank 10 than as indicated by adhesive regions 680. Moreover, adhesive and/or adhesive regions may be otherwise arranged or applied than as shown in FIG. 1.

As will be described below in more detail with further reference to FIGS. 3-7, blank 10 is intended to form container 700 as shown in FIG. 7 by wrapping, coupling, and/or securing panels 22, 24, 26, 28, 30, 32, 34, 36, 38, minor tabs 302, 304, 306, 308, 402, 404, 406, 408, 502, 504, 602, 604, bottom major flaps 102, 202, and top major flaps 152, 252. In one embodiment, the panels and flaps are wrapped, coupled, and/or secured in order to reduce gaps in a container. Furthermore, it is apparent that those skilled in the art and from the teachings provided herein that blanks may have any suitable shape, size, and/or configuration that enables container 700 to perform as described herein.

In the example embodiment, when container 700 is formed from blank 10, the panels of blank 10 are rotated toward interior surface 12 such that end panels 22, 38 at least partially overlap each other. End panels 22, 38 are coupled or secured to each other using a suitable coupling or securing mechanism, such as an adhesive material. It is apparent to those skilled in the art and guided by the teachings herein provided that any suitable coupling or securing mechanism may be used to couple or secure end panels 22, 38. In one embodiment, as shown in FIGS. 3-8, end panel 38 overlaps end panel 22. In an alternative embodiment, end panel 22 overlaps end panel 38.

Panels 24, 26, 28, 30, 32, 34, 36 and overlapping coupled or secured end panels 22, 38 of blank 10 define side walls 724, 726, 728, 730, 732, 734, 736, and 722, respectively. In the illustrated embodiment, side walls 722, 724, 726, 728, 730, 732, 734, 736 are obliquely angled relative to adjacent side walls. In one embodiment, side walls 722, 724, 726, 728, 730, 732, 734, 736 are angled at about 135° with respect to adjacent side walls. However, it is apparent to those skilled in the art and guided by the teachings provided herein that other angles may be used for other embodiments of the present disclosure.

A cavity 710 (or void 710) is defined as the space circumscribed by side walls 724, 726, 728, 730, 732, 734, 736, 722. Cavity 710 has a top and a bottom. First bottom major flap 102 is rotated inwardly, that is, towards cavity 710, such that first bottom major flap 102 is substantially perpendicular to panel 36 and at least partially covers the bottom of cavity 710. First top major flap 152 is rotated inwardly such that first top major flap 152 is substantially perpendicular to panel 36 and at least partially covers the top of cavity 710.

As shown in FIG. 3, to construct a bottom 750 of container 700, after end panels 22, 38 are secured to form cavity 710, as described above-bottom corner flaps 402, 404, 406, 408 are rotated inwardly about respective fold lines into a substantially perpendicular relationship with side walls 722, 724, 726, 728, 730, 732, 734, 736. In addition, bottom minor flaps 602, 604 are rotated inwardly about respective fold lines into a substantially perpendicular relationship with side walls 722, 724, 726, 728, 730, 732, 734, 736. Accordingly, bottom corner flaps 402, 404, 406, 408 are substantially coplanar with bottom minor flaps 602, 604 in a plane 800 that is substantially perpendicular to side walls 722, 724, 726, 728, 730, 732, 734, 736. Bottom corner flaps 402, 404, 406, 408 and bottom minor flaps 602, 604 define a substantially flat inner layer 752 of bottom 750 of container 700. Inner layer 752 at least partially covers cavity 710.

More particularly, inner layer 752 includes a first region 751, defined by bottom corner flaps 402 and 404 and first bottom minor flap 602. The complementary shapes of bottom corner flaps 402, 404 and first bottom minor flap 602 prevents gaps or openings in first region 751, preventing the loss of product from container 700 along first region 751. At least a portion of second arcuate convex portion 422 of free edge 403 of first bottom corner flap 402 engages with at least a portion of first arcuate concave portion 612 of free edge 603 of first bottom minor panel 602 in a non-overlapping, gapless, and/or edge-to-edge relationship. In the example embodiment, the entire second arcuate convex portion 422 of free edge 403 of first bottom corner flap 402 engages with the entire first arcuate concave portion 612 of free edge 603 of first bottom minor panel 602 in a non-overlapping, gapless, and/or edge-to-edge relationship.

Similarly, at least a portion of second arcuate convex portion 424 of free edge 405 of second bottom corner panel 404 engages with at least a portion of second arcuate concave portion 622 of free edge 603 of first bottom minor panel 602 in a non-overlapping, gapless, and/or edge-to-edge relationship. In the example embodiment, the entire second arcuate convex portion 424 of free edge 405 of second bottom corner panel 404 engages with the entire second arcuate concave portion 622 of free edge 603 of first bottom minor panel 602 in a non-overlapping, gapless, and/or edge-to-edge relationship. Accordingly, first region 751 of inner layer 752 is has a planar and substantially continuous area extending from a first corner 770 defined between side wall 732 and side wall 730 and a second corner 772 defined between side wall 724 and side wall 726, to the bottom edges of side walls 730, 728, and 726.

Inner layer 752 further includes a second region 753, defined by bottom corner flaps 406 and 408 and second bottom minor flap 604. The complementary shapes of bottom corner flaps 406 and 408 and second bottom minor flap 604 prevents gaps or openings in second region 753, preventing the loss of product from container 700 along second region 753.

At least a portion of second arcuate convex portion 426 of free edge 407 of third bottom corner flap 406 engages with at least a portion of first arcuate concave portion 614 of free edge 605 of second bottom minor panel 604 in a non-overlapping, gapless, and/or edge-to-edge relationship. In the example embodiment, the entire second arcuate convex portion 426 of free edge 407 of third bottom corner flap 406 engages with the entire first arcuate concave portion 614 of free edge 605 of second bottom minor panel 604 in a non-overlapping, gapless, and/or edge-to-edge relationship.

Similarly, at least a portion of second arcuate convex portion 428 of free edge 409 of third bottom corner flap 408 engages with at least a portion of second arcuate concave portion 624 of free edge 605 of second bottom minor panel 604 in a non-overlapping, gapless, and/or edge-to-edge relationship. In the example embodiment, the entire second arcuate convex portion 428 of free edge 409 of third bottom corner flap 408 engages with the entire second arcuate concave portion 624 of free edge 605 of second bottom minor panel 604 in a non-overlapping, gapless, and/or edge-to-edge relationship. Accordingly, second region 752 of inner layer 752 is has a planar and substantially continuous area extending from a first corner 774 defined between side wall 732 and side wall 734 and a second corner 776 defined between side wall 724 and side wall 722, to the bottom edges of side walls 722, 736, and 734.

First bottom major flap 102 is rotated toward interior surface 12 of first major panel 24 (side wall 724) into a face-to-face relationship with inner layer 752, such that first bottom major flap 102 defines an intermediate layer 754 of bottom 750 of container 700. Intermediate layer 754 at least partially covers inner layer 752 and cavity 710. In the example embodiment, first bottom major flap 102, defining intermediate layer 754, covers cut lines or seams in first region 751 of inner layer 752, between first bottom corner flap 402 and first bottom minor panel 602, and between second bottom corner flap 404 and first bottom minor panel 602, to enhance the sift-resistance of container 700. Similarly, first bottom major flap 102, defining intermediate layer 754, covers cut lines or seams in second region 753 of inner layer 752, between third bottom corner flap 406 and second bottom minor panel 604, and between fourth bottom corner flap 408 and second bottom minor panel 604, to enhance the sift-resistance of container 700. In one embodiment, first bottom major flap 102 is coupled or secured to inner layer 752 by an adhesive material. In alternative embodiments, any suitable coupling material and/or mechanism may be used to couple or secure first bottom major flap 102 to inner layer 752. In the example embodiment, because length L₂ of first major panel 24 (side wall 724) is longer than length L₁ (described above), first bottom major flap 102 couples snugly against inner layer 752 without deformation of either first bottom major flap 102 or inner layer 752. Accordingly, intermediate layer 754 maintains inner layer 752 in a planar orientation, such that no gaps are formed in the corners between side wall 724, inner layer 752, and intermediate layer 754, further preventing the loss of product from container 700.

Second bottom major flap 202 is rotated toward interior surface 12 of second major panel 32 (side wall 732) into a face-to-face relationship with intermediate layer 754, such that second bottom major flap 202 defines an outer layer 756 of bottom 750 of container 700. Outer layer 756 at least partially covers intermediate layer 754. In one embodiment, second bottom major flap 202 is coupled or secured to intermediate layer 754 by an adhesive material. In alternative embodiments, any suitable coupling material and/or mechanism may be used to couple or secure second bottom major flap 202 to intermediate layer 754. In the example embodiment, because length L₃ of second major panel 32 (side wall 732) is longer than length L₂ (described above), second bottom major flap 202 couples snugly against intermediate layer 754 without deformation of either second bottom major flap 202, intermediate layer 754, or inner layer 752. Accordingly, outer layer 756 maintains intermediate layer 754 in a planar orientation, such that no gaps are formed in the corners between side wall 732, intermediate layer 754, and outer layer 756 further preventing the loss of product from container 700.

With reference to FIG. 5, to construct a top 760 of container 700, top corner flaps 302, 304, 306, 308 are rotated inwardly about respective fold lines into a substantially perpendicular relationship with side walls 722, 724, 726, 728, 730, 732, 734, 736. In addition, top minor flaps 502, 504 are rotated inwardly about respective fold lines into a substantially perpendicular relationship with side walls 722, 724, 726, 728, 730, 732, 734, 736. Accordingly, top corner flaps 302, 304, 306, 308 are substantially coplanar with top minor flaps 502, 504 in a plane 802 that is substantially perpendicular to side walls 722, 724, 726, 728, 730, 732, 734, 736. Top corner flaps 302, 304, 306, 308 and top minor flaps 502, 504 define a substantially flat inner layer 762 of top 760 of container 700. Inner layer 762 at least partially covers cavity 710.

At least a portion of second arcuate convex portion 322 of free edge 303 of first top corner flap 302 engages with at least a portion of first arcuate concave portion 512 of free edge 503 of first top minor panel 502 in a non-overlapping, gapless, and/or face-to-face relationship. In the example embodiment, the entire second arcuate convex portion 322 of free edge 303 of first top corner flap 302 engages with the entire first arcuate concave portion 512 of free edge 503 of first top minor panel 502 in a non-overlapping, gapless, and/or face-to-face relationship.

Similarly, at least a portion of second arcuate convex portion 324 of free edge 305 of second top corner panel 304 engages with at least a portion of second arcuate concave portion 522 of free edge 503 of first top minor panel 502 in a non-overlapping, gapless, and/or face-to-face relationship. In the example embodiment, the entire second arcuate convex portion 324 of free edge 305 of second top corner panel 304 engages with the entire second arcuate concave portion 522 of free edge 503 of first top minor panel 502 in a non-overlapping, gapless, and/or face-to-face relationship.

In the example embodiment, the entire second arcuate convex portion 326 of free edge 307 of third top corner flap 306 engages with the entire first arcuate concave portion 514 of free edge 505 of second top minor panel 504 in a non-overlapping, gapless, and/or face-to-face relationship.

Similarly, at least a portion of second arcuate convex portion 328 of free edge 309 of third top corner flap 308 engages with at least a portion of second arcuate concave portion 524 of free edge 505 of second top minor panel 604 in a non-overlapping, gapless, and/or face-to-face relationship. In the example embodiment, the entire second arcuate convex portion 328 of free edge 309 of third top corner flap 308 engages with the entire second arcuate concave portion 524 of free edge 505 of second top minor panel 604 in a non-overlapping, gapless, and/or face-to-face relationship.

First top major flap 152 is rotated toward interior surface 12 of first major panel 24 (side wall 724) into a face-to-face relationship with inner layer 762, such that first top major flap 152 defines an intermediate layer 764 of top 760 of container 700. Intermediate layer 764 at least partially covers inner layer 762 and cavity 710. In one embodiment, first top major flap 152 is coupled or secured to inner layer 762 by an adhesive material. In alternative embodiments, any suitable coupling material and/or mechanism may be used to couple or secure first top major flap 152 to inner layer 762. Second top major flap 252 is rotated toward interior surface 12 of second major panel 32 (side wall 732) into a face-to-face relationship with intermediate layer 764, such that second top major flap 252 defines an outer layer 766 of top 760. Outer layer 766 at least partially covers intermediate layer 764. In one embodiment, second top major flap 252 is coupled or secured to intermediate layer 764 by an adhesive material. In alternative embodiments, any suitable coupling material and/or mechanism may be used to couple or secure second top major flap 252 to intermediate layer 764.
