Pallet collar, a pallet collar system and use thereof

A pallet collar (1) made of a single paperbased sheet with a uniform thickness, said sheet having four consecutive sections (6a-d) each having a substantially rectangular, or rectangular mid part (7a-d) joined to a mid part (7a-d) of an adjacent section (6a-d) by a main folding line (8a-c) by making a right angle to that section (6a-d) so that each section (6a-d) forms a wall of the pallet collar (1),

• each pallet collar wall having an outer wall portion (9) and an inner wall portion (10) extending in parallel therewith and spaced apart therefrom,
• the outer wall portion (9) being formed by said mid part (7a-d),
• the mid part (7a-d) having at each of opposite borders thereof as seen in the direction of the extension of said main folding line (8a-c) a series of four consecutive parts (11a-b, 12a-b, 13a-b, 14a-b) each folded along a folding line (15a-b, 16a-b, 17a-b, 18a-b) perpendicular to said main folding line (8a-c) in the same sense while making a right angle to the preceding part (11a-b, 12a-b, 13a-b, 14a-b) and in the opposite sense with respect to the sense in which the parts (11a-b, 12a-b, 13a-b, 14a-b) of the other series of four consecutive parts (11a-b, 12a-b, 13a-b, 14a-b) are folded, so that following upon each other a first part (11a-b) of each series next to said mid part (7a-d) forms a first spacer between said outer (9) and inner (10) wall portions,
• a second part (12a-b) extends in parallel with the mid part (7a-d) and forms half of the inner wall portion (10), to a position in which it is substantially in contact with the second part (12a-b) of the other series at the center of the respective pallet collar wall,
• a third part (13a-b) extends to an inner side (19) of the mid part (7a-d) to form a second spacer between said outer (9) and inner (10) wall portions, and
• a fourth part (14a-b) extends along the inner side (19) of the mid part (7a-d) and is secured thereto.
