Abstract: A drip-proof inset includes a bottom and a U-shaped border surrounding the same, which border is composed of two side pieces and one back piece. Initially, the inset is in the shape of a plane sheet (A) that includes a number of scorings. Namely, two first scorings (8), along which two side pieces (3?) can be turned up at an angle to a bottom-forming part (1?) of the sheet, a second scoring (9), along which a back piece (4?) can be turned up at an angle to the bottom sheet part (1?), as well as at least one additional, third scoring (11) that extends halfway between two opposite edges (7) of the sheet in order to, before turning-up of said back and side pieces, enable folding of the sheet in the middle during formation of two folded-up sheet halves having a halved surface area.

Abstract: The invention relates to a sheet (1) intended for protecting purposes, comprising a bottom-forming part and a number of wall-forming edge portions, which each individually are foldable, via a scoring serving as a hinge, between a starting position in the same plane as the bottom part, and a folded-up position at an angle to the bottom part for forming a wall (6, 7). Characteristic of the invention is that in the area of an individual edge of the sheet, a set of several of parallel scorings (10, 12) that are placed close to each other is arranged, and an arbitrary scoring of which may be selected in order to form a hinge between the bottom part and a wall.

Abstract: The invention relates to a drip-proof inset of the type that comprises a bottom and a U-shaped border surrounding the same, which border is composed of two side pieces and one back piece. Initially, said inset is in the shape of a plane sheet (A) that includes a number of scorings, viz. two first scorings (8), along which two side pieces (3′) can be turned up at an angle to a bottom-forming part (1′) of the sheet, a second scoring (9), along which a back piece (4′) can be turned up at an angle to the bottom sheet part (1′), as well as at least one additional, third scoring (11) that extends halfway between two opposite edges (7) of the sheet in order to, before turning-up of said back and side pieces, enable folding of the sheet in the middle during formation of two folded-up sheet halves having a halved surface area.
