Definitions

  • This invention relates to a wrap-around article carrier and a production blank therefor in accordance with the preambles of claims 1 and 4 respectively. It concerns carriers which have end panels that are unattached to the bottom panel. More particularly, it relates to a wrap-around article carrier of this type which incorporates an improved locking means for holding the end panels in place.
  • Wrap-around beverage container carriers are available in many different styles and designs, some of which include end panels. End panels offer more area for printed material and also protect the labels on bottles from being scuffed or otherwise damaged during the passage of the bottles through the packaging machine and during subsequent handling. In order to provide these functions at a minimum of expense, end panels have been used which do not fully cover the ends of the carriers and which are not connected at their bottom edges to the bottom panel of the carrier, thus reducing the amount of paperboard required for each carrier blank. End panels of this type are normally foldably connected to tuck panels which themselves are foldably connected to the top and side panels of the carrier. This arrangement requires that the carrier be designed so as to prevent the end panels from unfolding and springing out from their generally vertical position.
  • U.S.-patent No. 3,398,856 issued on August 27, 1968 to Graser, discloses an end panel arrangement comprised of three foldably connected tuck flaps, the central tuck flap having edges which are designed to frictionally engage the necks of beverage bottles to hold the flaps and the end panels in place. While this design works well with beverage bottles having necks for the central tuck flap to engage, it could not be used effectively with bottles having no necks. Bottles of this type have wide openings and are shaped more like a jar, leaving little or no room for engagement with a tuck flap.
  • wrap-around carriers of the type discussed to package beverage containers having no necks and still be able to incorporate locking means for maintaining the end panels of the carriers in place.
  • a portion of the tuck flap means extends between the adjacent article in the carrier and the top panel of the carrier to lock the tuck flap means and the attached end panels in place.
  • Cutouts in the fold lines connecting the end tuck flaps to the center tuck flap produce edges on the center tuck flap which are adapted to overlie portions of adjacent articles between the article top and the top panel.
  • the cutouts also produce edges on the end tuck flaps which in a preferred embodiment, may be adapted to engage the sides of the adjacent articles a short distance below the top of the article to further support the tuck flaps.
  • a carrier blank 10 is comprised of a top panel section 12 foldably connected to side panel sections 14 along score lines 16.
  • the top panel section may be provided with a suitable handle, which for purpose of illustration is shown as a finger hole 18.
  • the side panel sections are also provided with cutouts 20 adjacent the score lines 16 for receiving the tops or bottle caps of containers packaged in the carrier.
  • the blank is shown as being designed to form a carrier for holding four containers, the invention is not limited to use in a four-pack carrier.
  • Both side panel sections are connected by score lines 22 to short sloped side panel sections 24, one of which is connected by score line 26 to an inner bottom panel section 28 and the other of which is connected by score line 30 to an outer bottom panel section 32. Cutouts 34 in the sloped sections 24 allow the heel portions of containers packaged in a carrier formed from the blank to extend therethrough to assist in holding the containers in place.
  • the outer bottom panel section 32 is illustrated as having alternate primary male locking tabs 36, a secondary locking aperture 38 and tertiary locking tabs 40.
  • the inner bottom panel section 28 is illustrated as having alternate primary locking edges 42, a secondary male locking tab 44 and tertiary female locking openings or notches 46.
  • each tuck section is comprised of a generally triangularly shaped center tuck flap 52 connected to the top panel section along the fold line 50 and two generally triangularly shaped end tuck flaps 54 connected to the center tuck flap along fold lines 56.
  • the fold lines 56 are interrupted by cutouts 58 bounded by center tuck flap edges 60 and end tuck flap edges 62.
  • Each of the cutout edges is curved to conform to the shape of the bottles or other containers to be carried in the carrier.
  • End panel sections or flaps 64 are connected to end tuck flaps 54 along fold lines 66 and to the side panel sections 14 along fold lines 68.
  • the fold lines 66 represent the edges of the end tuck flaps 54 and are shown as extending at a slight angle to the score lines 16.
  • the fold lines 68 are extensions of the edges of the side panel sections 14.
  • the blanks 10 are supplied to an automatic packaging machine which wraps the blanks around the beverage containers and secures the bottom panel sections together to form the intermediate form of carrier shown in FIG. 2.
  • the tuck flaps 52 and 54 extend outwardly from the top panel 12 and the end panel sections or flaps 64 extend outwardly at an angle to the tuck flaps and to the side panels 14.
  • the bottles B are securely held in the carrier by a combination of pressures, snugly fitting between the side panels 14 and partially extending through the heel cutouts 34.
  • the caps C of the bottles partially extend through the cap cutouts 20 to further assist in holding the bottles in place.
  • center tuck flap 52 Pressure applied by a packaging machine element (not shown) against the outermost portion of center tuck flap 52 causes the tuck flap 52 to fold inwardly about score line 50, carrying with it the end tuck flaps 54. This also causes the end panel flaps 64 to fold inwardly about the fold lines 68.
  • the fold lines 66 allow relative folding movement between the end panel flaps 64 and the end tuck flaps 54, and the fold lines 56 allow relative folding movement between the center tuck flap 52 and the end tuck flaps 54, such relative movements taking place as a consequence of the movement of the center tuck flap 52.
  • FIGS. 3 and 4A A final intermediate stage in the folding of the flaps is shown in FIGS. 3 and 4A.
  • the edges 60 and 62 of the cutouts separating the center tuck flap 52 and the end tuck flaps 54 swing through an arc carrying them in toward the bottles and up toward the top panel of the carrier.
  • the cutout edges 60 of the center tuck flap 52 engage the sides of the caps C, as best shown in FIG. 4A.
  • the cutout edges 62 of the end tuck flaps 54 have not yet reached the bottles B.
  • FIGS. 4B, 5, 6, 7 and 8 The completed carrier resulting from continued folding movement of the tuck flaps and end panel flaps is shown in FIGS. 4B, 5, 6, 7 and 8.
  • the end panel flaps 64 are substantially vertical and the cutout edges 62 are adjacent the lower portion of the caps C.
  • the cutout edges 62 may be in actual abutting contact with the caps C or may be slightly spaced therefrom. In either case, when the carrier is lifted by the finger hole 18 or other handle means which may be provided on the top panel, the lifting stresses tend to pull the end tuck flaps 54 and the cutout edges 62 in toward the caps C.
  • tear strips can be provided to facilitate removal of the bottles.
  • score lines can be provided in the side panels to cause the side panels to conform more readily to the sloped shape of the bottles between the caps and the barrel portion of the bottles, although the side panels will normally conform to the bottle outline even without such fold lines if properly dimensioned.
  • the length of the end panels may be varied as desired, since the locking means of the invention will function to hold any length of end panel in place at substantially right angles to the top and bottom panels of the carrier.
