Title: Packing cover
IPC: B65D81/02

Abstract: 1. Packing protector for protecting the edge areas of a sheet-like object, said packing protector consisting of an edge protector (1) and of flanges (2, 3) extending from the edge protector to opposite surfaces of the object to be protected, both the edge protector and the flanges being manufactured from cardboard, characterised in that the flanges (2, 3) and the edge protector (1) have been produced from a continuous cardboard sheet by folding it so that edge protector formed by narrow strips (5) forms an accordion or bellows type structure comprising joining areas (4) connecting adjacent strips (5) of the edge protector together so as to press the flanges obliquely toward each other. 2. Packing protector as defined in claim 1, characterised in that the joining areas (4) consist of glue spots. 3. Packing protector as defined in claim 1, characterised in that the joining areas (4) are disposed on the strip (5) surfaces facing toward the flanges. 4. Packing protector as defined in claim 1, characterised in that the joining areas (4) in different strips (5) are disposed along the same line across the width of the edge protector and at a distance from each other in the lengthways direction of the edge protector. 5. Packing protector as defined in claim 1, characterised in that the fold (6, 7) between the strips (5) is provided with incisions (8) to increase the elasticity of the edge protector in its widthways direction. 6. Packing protector as defined in claim 5, characterised in that the incisions (8) are placed along the same line with the joining areas (4). 7. Packing protector as defined in claim 5, characterised in that the incisions (8) are disposed in the inner folds (6) between strips (5). 8. Packing protector as defined in claim 1, characterised in that the packing protector is provided with a crosscut (9) cutting through a substantial portion of the flanges (2, 3) and edge protector (1) while the outer folds (7) between strips (5) and the folds (10) between the outermost strips and the flanges form a joint (11) along the crosscut line to allow the two parts (12, 13) of the packing protector to be bent to an angle relative to each other. 9. Packing protector as defined in claim 8, characterised in that the crosscut (9) is disposed alongside a line of joining areas and corresponding incisions (8) in the inner folds (6) between the strips (5) so that the joining areas and incisions lie on one side of the crosscut while the strips on the other side of the crosscut are connected together by the folds and are free of joining areas. 10. Packing protector as defined in claim 8, characterised in that the flanges (2, 3) are provided with bevelled indentations (14) at the edges of the crosscut (9) to allow the two parts (12, 13) of the packing protector to be bent to an angle of 90 degree C relative to each other. 11. Packing protector as defined in claim 8, characterised in that the flange (2, 3) is provided with a locking incision (15) near the crosscut (9) to allow the flanges to be interlocked when the parts of the packing protector are bent to an angle relative to each other. 12. Packing protector as defined in claim 8, characterised in that the edge of the flange (2, 3) comprises a bridge (16) at the beginning of the crosscut (9), which bridge is only torn when the packing protector is being bent to an angle.
