Abstract

Abstract Articles are assembled on a pre-cut blank of cardboard or like material which is formed into a tray around the articles, the tray having a substantially rectangular base with diagonal corners and first and second pairs of peripheral wall portions. The blank is scored and provided with cut-outs to form wall corner portions and uniting portions at the ends of corresponding first wall forming portions and also to form strengthening tabs. The tray is erected by first erecting the strengthening tabs and by then erecting the first and second wall forming portions and finally bending the corner portions and uniting portions so that the latter can be secured to the second wall forming portions.

Claim 1
Independent Claim 378 words
A package formed from a plurality of articles and a tray blank of cardboard or like material, said tray blank comprising: a. a substantially rectangular base portion having diagonal corners and defined by first and second pairs of parallel score lines and by a respective diagonal score line at each corner; b. first and second pairs of peripheral wall portions defined bY said first and second pairs of parallel score lines and by the periphery of the blank; c. a uniting portion and a wall corner portion defined at each end of each of said first pair of peripheral wall portions by the end of the peripheral wall portion, the periphery of the blank, and a pair of parallel score lines, the uniting portion being nearer the end of the wall portion and said pair of parallel score lines being spaced apart by a distance substantially equal to the length of the diagonal score line; d. a cut-out and a substantially rectangular strengthening tab at each corner of the blank, said tab at each said corner being defined by said diagonal score line at the corner, the cut-out at the corner and a pair of cuts between said pair of parallel score lines defining said uniting and wall corner portions at the associated corner, said pair of cuts being substantially at right angles to one another, and said cut-out at each corner being defined by said tab at the corner, the end of the peripheral wall portion of the second pair thereof at the corner and said uniting portion at the corner; said articles being disposed in an ordered array on said base portion of said blank and said peripheral wall portions being folded about said first and second pairs of parallel score lines whereby they are erected around said articles; said uniting and wall corner portions at each corner being folded about said pair of parallel score lines defining them such that said wall corner portions form diagonal wall corners; each said uniting portion being secured to an end of one of said second pair of peripheral wall portions; and each said strengthening tab being folded about said diagonal score line defining it so that it is inside and adjacent to the corresponding wall corner forming portion.
