  • the fold line 43 may be arranged to disposed in alignment with an upper end of a main body of the articles B being packaged.
  • the fold line 43 may be arranged to be aligned with a joint or transition between main body of the articles B and a shoulder or neck portion of the articles B.
  • the keel tab 40 interrupts an engaging or support edge of the first inner shoulder panel 14 C; the portion of the first inner shoulder panel 14 C which the keel tab 40 removes would otherwise form a part of the support edge defined by the cutline or slit forming the article engaging device 72 A. It has been found that portions of the first inner shoulder panel 14 C disposed on opposing sides of the keel tab 40 provide engaging or support edges which are sufficient to retain the article B within article engaging device 72 A or carrier 90 .
  • FIG. 2 illustrates a carrier 90 , formed from the blank 10 , engaged with a group of articles B.
  • Each of the article-engaging devices 70 A, 72 A, 70 B, 72 B of the blank 10 engages an upper end of an article B of the group of articles B. Portions of the articles B pass through the main panel 14 and engage therewith.

  • the keel tabs 40 are folded out of the main panel 14 and extend inwardly or downwardly. Each keel tab 40 is disposed between a pair of articles B, best shown in FIGS. 3 and 4 . The keel tabs inhibit the pair of articles B from contacting each other directly—at least at an upper end.
  • Adhesive may be applied to the keel tabs 40 (or to corresponding regions of the articles B) such that each article B adjacent to a keel tab 40 may be adhesively secured thereto.
  • An article B may be adhesively secured to both or opposing faces of the keel tabs 40 —that is to say one article may be adhesively secured to one of the opposing faces of a keel tab 40 and another article may be adhesively secured to the other one of the opposing faces of said keel tab 40 . This may improve security of the articles B with in the carrier 90 .
  • a fugitive glue may be employed to secure the keel tabs 40 to the articles B.
  • An example of a specific glue is Swift® melt 7044 manufactured by HB Fuller.
  • a fugitive glue is optional, an advantage of a fugitive glue is its tendency to remain attached to the carrier 90 when the articles B are disengaged from the carrier 90 (this may be more desirable than having the glue remain attached to the articles B).
  • other adhesives maybe employed such as, but not limited to, hot-melt glue.
  • the keel tabs 40 may inhibit or prevent damage to the articles B from impact or contact between the pair of articles B.
  • the keel tab 40 may also suppress noise when the carrier 90 is transported.
  • the keel tab 40 may also improve security of the keel structure formed by the inner shoulder panels 14 C, 14 D.

Any reference to “hinged connection” should not be construed as necessarily referring to a single fold line only; indeed a hinged connection can be formed from two or more fold lines wherein each of the two or more fold lines may be either straight/linear or curved/curvilinear in shape. When linear fold lines form a hinged connection, they may be disposed parallel with each other or be slightly angled with respect to each other.
