Abstract
Means for holding the bottoms of petaloid shaped bottles in place in a wrap-around carrier. Side panel apertures include flaps connected to the side panel by fold lines which are inwardly curved at their upper portions. The lower portions of each pair of flaps extend toward each other so as to engage one or more support feet of the adjacent bottle and be forced out from the side panel thereby. The curved portion of the fold lines biases the flaps against the support feet, regardless of which portion of the feet engage the flaps, to assist in holding the bottles in place within the carrier. Fold lines extending from the flap edges to the flap fold lines and hook-shaped slits at the upper ends of the flaps allow the side flaps to flex lengthwise.

A wrap-around carrier package containing a plurality of articles having bottom portions which include spaced support feet, comprising:
- opposite side panels foldably connected to top and bottom panels;
- the side panels having bottom portions containing apertures opposite the bottom portions of adjacent articles;
- each aperture being partially covered by opposed side flaps each connected to the side panel along a fold line, each side flap having an outer side edge portion spaced from the outer side edge portion of an opposed flap wherein each aperture is uncovered between the outer side edge portions of it's associated flaps.
- The side flap fold lines of each aperture having upper portions which are curved toward each other and have an upper end portion, the upper end portions of the side flap fold lines of each aperture being spaced from each other;
- each side flap being in contact with a support foot of an adjacent article, at least some of the side flaps being outwardly pivoted thereby;
- the curved portions of the side flap fold lines biasing the side flaps toward the interior of the carrier to assist in holding the articles in place within the carrier;
- and
- flex enhancing fold lines extending from the outer side edge portion of each of the side flaps to the side flap fold lines, said flex enhancing fold lines acting to enhance the ability of the side flaps to flex along the length of said side flaps.
A wrap-around carrier package containing a plurality of beverage bottles having petaloid shaped bottom portions which include spaced support feet, comprising:
- opposite side panels foldably connected to top and bottom panels;
- the side panels having bottom portions containing apertures opposite the bottom portions of adjacent bottles;
- each aperture being partially covered by opposite side flaps each connected to the side panel along a fold line, each side flap having an outer side edge portion spaced from the outer side edge portion of an opposed flap wherein each aperture is uncovered between the outer side edge portions of it's associated flaps;
- the side flap fold lines of each aperture having upper portions which are curved toward each other and having an upper end portion, the upper end portions of the side flap fold lines of each aperture being spaced from each other;
- the distance between the side flaps of each aperture and the distance between the side flap fold lines of each aperture being related to the dimensions of the support feet so that each flap is in contact with and outwardly pivoted by a support foot of an adjacent bottle,
- curved portions of the side flap fold lines biasing the side flaps toward the interior of the carrier to assist in holding the bottles in place within the carrier and
- a slit extending from the upper end portion of the curved portion of each side flap fold line and terminating in the side panel in a hooked end portion,
A generally rectangular blank for forming a wrap-around carrier adapted to package a plurality of articles having bottom portions which include spaced support feet, comprising:
- a first side panel section foldably connected to and positioned between a top panel section and a first bottom panel section, and a second side panel section foldably connected to and positioned between said top panel section and a second bottom panel section;
- portions each of the side panel sections adjacent the bottom panel sections containing apertures for positioning opposite the bottom portions of adjacent articles in a carrier formed from the blank;
- each aperture being partially covered opposed side flaps each connected to the side panel section along a fold line each side flap having an outer side edge portion spaced from the wherein each aperture is uncovered between the outer side edge portions of its associated flaps;
- the side flap fold lines of each aperture having portions on an end of each aperture opposite said bottom panel sections;
- which are curved toward each other, each curved portion having an end portion, the end portions of the side flap fold lines of each aperture being spaced from each other;
- said flaps for contacting with a support foot of an adjacent article carried in a carrier formed from the blank whereby at least some of the side flaps are for pivoting outwardly by the support feet of an article in a carrier formed from the blank;
- the curved portions of the side flap fold lines biasing the side flaps toward the interior of 9 carrier formed from the blank to assist in holding the articles in place within the carrier;
- and
- flex enhancing fold lines extending from the outer side edges of each of the side flaps to the side flap fold lines.
