Definitions

  • the present invention relates generally to cartons or cartons, and specifically, to a panel interlocking arrangement for ensuring a rigid connection between panels secured together in an overlapping arrangement.
  • Wrap-around cartons and hand-pack top loaded cartons are known, and have been long used as efficient, attractive, and convenient secondary packaging for holding, storing, and carrying multiple articles.
  • such cartons and cartons are useful for grouping and carrying multiple beverage containers while exposing the beverage containers for visibility and economy of material use.
  • Wrap-around cartons and top-loaded cartons are typically top gripping, that is, they can be lifted from above using a handle component.
  • the carton or carton will frequently include interlocking assemblies that mechanically lock overlapping panels together, as the lower wall of the carton typically must bear the weight of the contents without reinforcement. Accordingly, the panels of the carton must be securely and reliably locked together to prevent separation of the overlapping panels of the bottom wall, or undesirable shifting of the container group as the carton or carton is being carried.
  • arrangement provides a very rigid connection between the two panels, in that it restrains the two panels from moving away from each other along a notional plane defined between the overlapped panels, it restrains the panels from moving toward each other along the notional plane, it restrains the panels from moving laterally with respect to one another, and it restrains the panels from moving away from each other in a direction that is normal to the notional plane defined between the panels.
  • the invention in one aspect provides a panel interlocking
  • the female locking tab is struck from the first panel and is foldably connected at its proximal end edge to the first panel such that a first opening is defined in the first panel when the female locking tab is folded out of a plane of the first panel.
  • the female locking tab includes a neck section and a head section hingedly connected to the neck section by a fold line.
  • the neck section extends between the fold line and the proximal end edge of the female locking tab whereas the head section extends between the fold line and a distal end edge of the female locking tab.
  • the male locking tab is struck from the second panel and is foldably connected at its proximal end edge to the second panel such that a second opening is defined in the second panel when the male locking tab is folded out of a plane of the second panel.
  • the proximal end edge of the male locking tab is disposed substantially parallel to a free edge of the second panel with the second opening interposed therebetween.
  • the first and second panels are arranged such that the first and second openings are in substantial alignment and such that part of the second panel along its free edge is disposed between the first opening and the neck section of the female locking tab.
  • the male locking tab is folded out of the plane of the second panel and received in the first opening of the first panel to take a folded position.
  • the female locking tab is folded along the fold line such that the head section of the female locking tab is received in the first and second openings and is disposed at a retaining position where the head section is in a mutually bracing engagement with the male locking tab to retain the male and female locking tabs in the folded and retaining positions respectively.
  • the distal end edges of the male and female locking tabs may be disposed over one side of the first panel.
  • the free edge of the second panel may be disposed in abutment on the female locking tab such that the free edge of the second panel is in substantial alignment with the proximal end edge of the female locking tab.
  • the part of the second panel along the free edge of the second panel may include a portion between the second opening and the free edge of the second panel.
  • the first opening of the first panel may have an inner end to which the proximal end edge of the female locking tab is foldably connected, and the male locking tab in the folded position may be in engagement with an outer end of the first opening opposite to the inner end of the first opening.
  • the second opening of the second panel may have an inner end to which the proximal end edge of the male locking tab is foldably connected, and the head section of the female locking tab in the retaining position may be in engagement with an outer end of the second opening opposite to the inner end of the second opening.
  • the head section of the female locking tab in the retaining position may brace against the male locking tab.
  • the male locking tab may lean against the distal end edge of the head section of the female locking tab.
  • the male locking tab in the folded position may brace against the head section of the female locking tab.
  • the head section of the female locking tab may lean against the distal end edge of the male locking tab.
  • At least one of the male and female locking tabs may include a shoulder section that is substantially wider than the remainder of the at least one of the male and female locking tab.
  • one of the male and female locking tabs may include an extension tab projecting from the distal end edge of the one of the male and female locking tabs, and the other of the male and female locking tabs may be provided with complementary cutout for receiving the extension tab.
  • the invention in a second aspect provides a blank for forming a panel interlocking arrangement.
  • the blank comprises a pair of first and second panels that are to be disposed in an overlapping relationship when the arrangement is formed; and a pair of male and female locking tabs for cooperation with one another to secure the first and second panels together in the overlapping relationship.
  • the female locking tab is struck from the first panel and is foldably connected at its proximal end edge to the first panel such that a first opening for receiving both the male and female locking tabs is defined in the first panel when the female locking tab is folded out of a plane of the first panel.

  • the carton 20 (FIG. 3) includes a composite handle panel H, which is formed from a number of other panels defined in the blank 10. Specifically, the blank 10 includes a center panel 122 with finger-hold apertures A, a handle reinforcing panel 124 with complementary finger-hold apertures A, and a divider panel 126 that may also include one or more finger-hold apertures A.

Abstract

L'invention porte sur un agencement d'emboîtement de panneaux qui permet de fixer entre eux un premier panneau (146) et un second panneau (148) dans une relation de chevauchement. L'agencement comprend une patte de verrouillage femelle (F) formée dans le premier panneau et une patte de verrouillage mâle (M) formée dans le second panneau. La patte de verrouillage femelle peut être déplacée de façon à définir une première ouverture (O) dans le premier panneau pour recevoir tout à la fois les pattes de verrouillage mâle et femelle. La patte de verrouillage femelle comprend une section de col (220) par laquelle la patte de verrouillage femelle est reliée au premier panneau, et une section de tête (222, 224) reliée de façon pliable à la section de col par une ligne de pliage (228). La patte de verrouillage mâle peut être déplacée de façon à définir une seconde ouverture dans le second panneau pour recevoir la patte de verrouillage femelle.
