Cassette for display unit and blank therefor

Abstract

A cassette obtainable from a blank having a chassis and first and second compression members is provided. The chassis has a series of four first parallel folding lines, a second and a third folding lines individuating a series of a closure flap, a cover panel, a front panel, a bottom panel and a rear panel. The second and third folding lines respectively individuate a left flap of each panel and a right flap of each panel, each of the left and right flaps being separated from adjacent left and right flaps by cuts. A first compression member has a center panel fixed to an internal face of the chassis on the rear panel. A second compression member is fixed to the internal face of the chassis on the cover panel. The cover panel has detachment lines delimiting first and second foldable buffers. The front panel has detachment lines delimiting a winglet.

         4 . The blank of  claim 3 , wherein said left and right quadrilateral flaps of the cover panel, and said left and right side panels of the first compression member have respective handhold holes. 
     
     
         5 . The blank of  claim 1 , wherein said winglet has a substantially rectangular shape and is provided of at least one finger hole adjacent to a side parallel to said one first folding line. 
     
     
         6 . The blank of  claim 1 , wherein said detachment lines delimiting the first and second foldable buffers, include for each buffer a first length along the first folding line, a second length orthogonal to the first length, a third length orthogonal to the second length, a fourth length orthogonal to the third length, a fifth length orthogonal to the fourth length and a sixth length along the second or third folding line, respectively, and wherein said third length is prolonged by a further folding line until the second or third folding line, respectively, and said fourth length is prolonged by an additional folding line until the first folding line. 
     
     
         7 . The blank of  claim 6 , wherein said cover panel has a respective finger hole adjacent to an intersection of the third and fourth lengths of each buffer. 
     
     
         8 . The blank of  claim 1 , wherein said second and third folding lines are substantially perpendicular to said four first parallel folding lines. 
     
     
         9 . A cassette obtainable from a blank comprising:
 a chassis having a series of four first parallel folding lines, a second folding line and a third folding line transversal to said four first parallel folding lines, wherein said first, second and third folding lines individuate a series of a quadrilateral closure flap, a quadrilateral cover panel, a quadrilateral front panel, a quadrilateral bottom panel and a quadrilateral rear panel, wherein said second folding line individuates a respective left quadrilateral flap of each panel, and wherein said third folding line individuates a respective right quadrilateral flap of each panel, each of the left and right quadrilateral flaps being separated from adjacent left and right quadrilateral flaps by cuts which extend along a prolongation of a respective first folding line,   a first compression member comprising at least a center panel fixed to an internal face of the chassis in correspondence of the rear panel, and   a second compression member fixed to the internal face of the chassis in correspondence of the cover panel,   wherein said cover panel has detachment lines delimiting first and second foldable buffers attached to oblique folding lines delimiting respective rear left and rear right corner portions, and wherein said front panel has detachment lines delimiting a winglet attached to one first folding line,   by folding said panels and flaps about the respective folding lines, so as said bottom panel and a third compression member, if present, constitute a bottom wall of the cassette, the cover panel and the second compression member constitute a top wall of the cassette, said front panel constitutes a front wall of the cassette, said rear panel and the center panel of the first compression member constitute a rear wall of the cassette, said left quadrilateral flaps and a left side panel, if present, of the first compression member constitute a left side wall of the cassette, and said right quadrilateral flaps and a right side panel, if present, of the first compression member constitute a right side wall of the cassette.   
     
     
         10 . A display unit comprising a supporting frame having left and right side walls and a rear wall defining a frontally open cavity wherein a plurality of cassettes according to  claim 9  are superposed, and wherein the foldable buffers of at least one cassette are folded at 180° about the respective oblique folding line and distance the cassette from the respective side wall and/or the rear wall of the supporting frame, and wherein the winglet is folded at 270° about the one first folding line and superposed on an adjacent portion of the cover panel. 
     
     
         11 . The blank of  claim 1 , wherein the center panel is glued to the internal face of the chassis in correspondence of the rear panel.
