  • Box 150 with the contained goods may then be transported or stored.
  • box 150 with the contained goods may be conveniently placed on a storage or display shelf.
  • Box 150 may be opened by tearing off tear strips 138 and 148, thus separating a portion of each of top panel 130, side panel 140, and side flaps 136, 137, 146, 147 from the remainder of box 150 along the tear lines provided by tear strips 138 and 148.
  • box 150 may be opened by tearing off tear strips 138 and 148 within a limited space, such as on a storage or display shelf. As tear strips 138 and 148 are located on the top or in the front of box 150, it is not necessary to remove any portion of box 150 at the back of box 150, which may be inconvenient to do when box 150 is placed on a shelf.
  • box 150 forms a display box 160 with partially opened top and front, as shown in FIG. 1G . Therefore, the goods placed in box 150 become accessible and visible in box 160. It is not necessary to remove the goods from box 150 or 160 to place them on the shelf, to view them, or to access them. A user can conveniently remove the goods from the partially open box 160, either from the open front side or the open top.
  • relatively large items may be stored in box 150 on a shelf and may be conveniently displayed and removed from display box 160.
  • back panel 120 and top panel portion 139 and other remaining portions of side flaps can conveniently provide structural support for confining the goods on display.
  • back panel 120 can prevent the goods from falling off the shelf from the back side.
  • tear strips 138 need to be properly positioned in blank 100.
  • tear strip 138 should be positioned away from end edge 131 by a distance that is substantially equal or greater than the width of side flaps 128 and 127, as depicted.
  • tear strip 138 may be distanced from edge 131 such that in box 150 the tear line provided by tear strip 138 is aligned with the free edge of each of side flaps 126 and 127.
  • tear strip 138 may be moved closer to edge 131, and the width of side flaps 126 and 127 may be correspondingly reduced.
  • the tear strips are positioned so that when the tear strips are torn off, the desired portions of top panel 130, front side panel 140, and selected side flaps are each at least partially removed.
  • tear lines provided by tear strips 138 and 148 in blank 100 are substantially straight lines. Blanks with straight tear lines may be easier to design and produce. Further, the openings formed by removal of the removable portions along the tear lines may be conveniently adjusted when the tear lines are straight and are substantially parallel to the edges of top panel 130.
  • each side flap 136, 137, 146, 147 is also conveniently removed when tear strips 138 and 148 are torn off.
  • two openings may be formed in the sides of box 150 by the gaps between side flaps 116, 126, 136, 146, 117, 127, 137, 147 .
  • These openings may be conveniently utilized to handle the box, and to provide a viewing window for viewing the content in box 150 without opening it. Further, less material is needed as compared to a box with fully covered sides.
  • the design of blank 100 allows the openings to be formed during assembly, without having to form openings in blank 100 during fabrication of the blank.
  • the size and position of the openings may be conveniently adjusted by adjusting the sizes of one or more of side flaps 116, 126, 136, 146, 117, 127, 137, 147.
  • side flaps 116, 126, 136, 146, 117, 127, 137, 147 may also be sized so that they cover the entire side of the box formed by these side flaps and no opening is left.
  • blank 100 as a whole is substantially rectangular. As such, it is easier to produce and waste of material is limited during production, as compared to production of blanks that have irregular shapes and varying widths along their lengths.
  • blank 100 or other blanks described herein may be formed using various different types of known methods and systems for forming such blanks, appropriately adapted to form the features disclosed herein.
  • the making of a blank 100 from a corrugated fibreboard material can start with making with first forming a sheet of corrugated material using a corrugator machine, such as one provided by BHS Corrugated Maschinen- und Anlagenbau GmbHTM.
  • the corrugator machine may produce a length of corrugated material of a given width that can be used immediately or stored in a roll until it is ready to be utilized.
  • the next step may involve utilizing a roll or sheet of such corrugated material that may have an approximate width that may be the same as the width of the desired blank that may be used to form the case.
  • the roll or sheet can be also cut transversely such as to create sections of cardboard that are generally rectangular in shape.
  • the corrugated material may then be fed through what is known as a flexo-folder gluer machine. In passing through such a machine, the corrugated sheet may pass through a printer, which prints words or pictures on one or both sides of the sheet.
  • the material may be creased both across and along the sheet material such that when the blank is folded/erected it may easily bend along the crease (fold) lines to form the desired shape.
  • the creased sheet may then be "slotted" with a slotting device which cuts thin transversely oriented "slots" in the board in intervals along a desired direction. These slots create the panels that may be folded.
  • the sheet material may go through a rotary die cutter to remove excess corrugated material along one end of the board and crush down a portion along a fold line, to create a thin "hinge".
  • the purpose of the hinge is to later allow the board to be doubled back on itself (i.e. glue one end of the board to the other to create a tube) and glued.
  • tear strips 138 and 148 may be formed in the blank such as by applying a device to create perforations in the blank.
  • a steel die may be pre-applied to a part of the blank to form the perforations.
  • the result up to this point can be a flat blank. Thereafter a flexo-folder gluer may apply glue to the hinge portion of the blank. The panels of the blank are then folded over by a folding mechanism such that one end of the blank is now glued to the other in a flattened tube-shaped orientation to create a flat tubular shaped blank such as is shown in FIG. 1C .
  • tubular shaped blank After the tubular shaped blank has been created, it may be grouped with other blanks and shipped to another location where the boxes are to be erected and packed.
  • the box can be erected from its knock-down configuration, either by hand or using a "case erector" machine.
  • case erectors include case packers made by iPak Machinery Ltd.TM
  • the second step may be the placing of the products into the formed case, either by hand or using a "case packer" machine.
  • case packers include case packers made by iPak Machinery Ltd.TM of Canada.
  • the box can then be sealed with the product inside.
  • FIG. 1C It may also be possible to utilize blanks that have not been formed into tubular forms such as in FIG. 1C in a first step, but rather using flat blanks and a wrap around machine.
  • An example of a commercial wrap around machine is available from CERMAXTM of France.
  • the wrap around machine utilizing a flat blank, may place one or more products on one panel such as panel 110 and then cause the remaining panels to be folded around and glued in the sequence identified in FIGS. 1A to 1F .
  • blank 100 may be modified without losing all of its benefits.
  • a tear line may be provided in another suitable form.
  • a tear line may refer to any line or elongated portion in the blank that is configured or adapted to facilitate the removal of a portion of the blank. Tear lines may be provided in the form of tear-away or tear-out strips, pull strips, tear- or pull-away tabs, perforation lines such as punch-out perforation lines, score lines, thinned or weakened strips or sections, or the like.

  • Box 250 has a bottom formed from bottom panel 210, a top formed from top panel 230, closed sides formed from side panels 220, 240, and partially open sides respectively formed from side flaps 216, 226, 236, and 246, or 217, 227, 237, and 247.
  • tear strips 238, 239 may be distanced from edges 231, 233 so that tear strips 238, 239 are aligned or clear of the free edges of side flaps 226, 227 and 246, 247, respectively. Such alignment or clearance allows convenient removal of tear strips 238, 239 with the removable portions of top panel 230 and side flaps 236, 237.
  • Display box 260 has a closed bottom (formed from panel 210), two closed sides (formed from panels 220 and 240), an open top, and two partially open sides (formed mainly by flaps 216 and 217).
  • the four vertical edges of box 260 are reinforced with the folded flaps 226, 227, 246, 247.
  • the reinforced edges may have a substantially triangular prim shape as depicted in FIGS. 2B, 2C, 2D, and 2F .
  • the triangular support edges may be vertically oriented during use to provide improved support, such as when boxes are stacked one on top of another. When the removable top portion is removed, the remaining reinforced edges may also provide improved support for the remaining side panels 220, 240.
  • tear-strip(s) may be provided on blank 200, such as on panel 240 parallel to edge 241, or on flaps 216 and 217, so that front panel 240 may be conveniently removed, either partially or completely, during use.
  • the reinforced edges may be formed of double-folded flaps, as shown in FIGS. 3A , 3B, 3C, 3D, 3E, and 3F .
  • Blank 300 shown in FIG. 3A is similar to blank 200, except that flaps 326, 327, 346, 347 each has only one fold line 328 or 348. Blank 300 may be folded to form a box 350, and then transformed to display box 360, in a similar manner as for forming box 250 and display box 260 from blank 200, as illustrated in FIGS. 3B, 3C, 3D, 3E, and 3F . A difference is that flaps 326, 327, 346, 347 only need to be folded once to form double layer.
  • edges reinforced by folded flaps 226, 227, 246, 247 may be stronger.
  • edges reinforced by folded flaps 326, 327, 346, 347 may provide sufficient strength in some applications, and blank 300 and box 350 may be easier to form as compared to blank 200 and box 250.
  • FIG. 4A shows another blank 400 .
  • Blank 400 is similar to blank 100, but with the differences discussed below.
  • blank 400 includes serially attached bottom panel 410, side panel 420, top panel 430, and side panel 440.

  • End flap 415 is also attached to two side flaps 418, 419.
  • Two side flaps 426, 427 are attached to side panel 420.
  • Two side flaps 436, 437 are attached to top panel 430.
  • An end flap 445 and two side flaps 446, 447 are attached to side panel 440. Tear lines are provided by way of tear strip 438 on panel 430 and tear strip 448 on panel 440.
  • Blank 400 may be folded as shown in FIGS. 4B, 4C, 4D, and 4E , to form box 450.
  • a fold line is provided on each of side flaps 418, 419, 426, 427, 446, 447 so that each of these side flaps may be folded to form a double layer to provide a reinforced edge in box 450, as illustrated.
  • Portions of the top and front of box 450 may be removed by tearing off tear strips 438 and 448, to form a display box 460 as shown in FIG. 4F .
  • the length of side flaps 418 and 419 are approximately equal to the width of side flaps 416 and 417; and tear strip 448 is aligned with the edges of side flaps 416, 417, 418 and 419 in box 450.
  • tear strip 448 is aligned with the edges of side flaps 416, 417, 418 and 419 in box 450.
  • a blank such as blank 400, may be fully assembled on a case erector, following the procedure shown in FIGS. 4B to 4E .
  • blank 400 may be partially pre-assembled such as shown in FIGS. 4B , 4G and 4H , before being assembled on a case erector such as shown in FIGS. 4I , 4D, and 4E , in that order.
  • a case erector such as shown in FIGS. 4I , 4D, and 4E
  • panels 430 and 440 may be folded together along the edge between panels 420 and 430, towards panels 410 and 420, as shown in FIG. 4G .
  • the partially assembled blank is flattened as depicted in FIG. 4H and is thus convenient to store and transport before being completely assembled.
  • End flap 445 may be glued to end flap 415 during preassembly or at a later time.
  • FIGS. 5A , 5B, 5C, 5D, and 5E show a blank 500 for forming a box 550 and display box 560, which are similar to blank 400, box 450 and display box 460, except that the corner edges are reinforced with triangular prism shaped supports that are formed by side flaps 518, 519, 526, 527, 546, 547, folded along two fold lines, similar to the corner supports in box 250 formed from blank 200.
  • a shipping and display container may be formed from a single blank according to exemplary embodiments of the present invention disclosed herein.
  • manufacture and assembly process may be simplified as compared to boxes or containers that are formed from multiple pieces of blanks.
