FIELD OF THE INVENTION
[0001] This invention relates to a partition, formed of a unitary blank of foldable paperboard, for locating and protecting bottles within a box, and to a blank for forming said partition. One or more such partitions may be located in a box to separate and protect of items of the cylindrical bottle type arranged in the box for transportation, where the partition prevents the contact between the items and protects the items from damage.
BACKGROUND OF THE INVENTION
[0002] Separators or partitions are used inside of boxes or containers in order to generate separate cavities to isolate the objects contained in the box from each other, avoiding contact between them, especially when the objects are made of a fragile material such as glass. Glass bottles are particularly vulnerable to breakage when several bottles are packed within a box due to direct contact between them. Therefore it is known to provide separators or partitions adapted to avoid contact between the bottles and to protect the bottles from impacts and scratches that can also damage labels, with the resulting loss of quality of the product.
[0003] Several solutions have been developed related to the use of sheets, cardboard plates or buffering materials arranged among bottles, where the main challenge is always to get an efficient separator capable of avoiding contact among bottles efficiently, but at the same time being cheap to produce and easy to install and providing sufficient impact protection for the individual bottles. Furthermore, known separators or partitions, while relatively effective at separating individual bottles from contact with one another, do little to protect the bottles from external impacts, instead relying entirely on the strength of the outer box within which the separator or partition is inserted.
[0004] An object of the present invention is to provide an improved partition for locating and protecting bottles within a box of low cost, easy to install and which form optimises the separation and protection of the bottles.

[0024] A first closure flap 72 extends from a top edge of the base panel 2 about an eleventh fold line 74 extending parallel to the third fold line 22 and bottom edge of the base panel 2, wherein, when the blank is folded to form the partition, such flap 72 defines a closure adapted to close the upper ends of the bottle receiving cavities defined within the partition.
[0025] A second flap 76 extends from a bottom edge of the first front panel 12 about a twelfth fold line 78, a third flap 80 extending from a bottom edge of the second front panel 14 about a thirteenth fold line 82, the second flap 76 being adapted to lie against the second link panel 28 and the third flap 80 being adapted to lie against the third link panel 32 to define respective parts of a bottom wall of a respective cavity when the blank is folded to form the partition.
[0026] As illustrated in Figures 2 to 7, in order to fold the blank into a partition for locating and protecting bottles within a box, the first and second front panels 12,14 are folded about the respective second fold lines 16,18 to extend perpendicular to the base panel 2 and the second and third flaps 76,80 are folded about the twelve and thirteenth fold lines 78,82 to extend perpendicular to the first and second front panels 12,14, as shown in Figure 2.
[0027] The first, second and third link panels 20,28,32 are folded about respective third, fifth and sixth fold lines 22,30,34, as shown in Figure 3, such that the first, second and third link panels 20,28,32 and the third and fourth side panels 36,40, third front panel 24 and the fourth and fifth link panels 44,46, all lying in a common plane, extend perpendicular to the base panel 3.
[0028] Next the third front panel 24, third side panel 36, and fourth side panel 40 are folded about said fourth, seventh and eighth fold lines 26,38,42 respectively such that the third front panel 24 lies parallel to and spaced from the base panel 2, the third side panel 36 lies parallel to and spaced from the first side panel 4, and the fourth side panel 40 lies parallel to and spaced from said second side panel 6, as shown in Figure 4, with the first and second further panels 48,50 extending outwardly from the third and fourth side panels 36,42.
[0029] Next the first and second side panels 4,6 are folded with respect to the base panel 2 about respective first fold lines 8,10, the fourth and fifth link panels 44,46 at the same time folding with respect to the third front panel 24 and the third and fourth side panels 36,40 about respective fold lines such that the fourth and fifth link panels 44,46 lie against respective third and fourth side panels 36,50 and extend perpendicular to the base panel 2 such that said partition defines three parallel cavities for receiving respective bottles therein.
